Manual

Easy-to-remove retractor

Technical Field

The utility model relates to safety belt equipment, in particular to a retractor which is convenient for disassembly and assembly.

Background technique

The retractor is mainly used for winding and retracting the seat belt. The main structure of the retractor includes a mounting frame, a coil spring, a tape winding shaft, etc. The traditional retractor mounting frame is often an integral structure. When the retractor needs to be disassembled, it can be replaced safely When the belt is used, it is often necessary to disassemble the coil spring first, then disassemble the belt winding shaft, and finally disassemble the installation belt, which makes the overall disassembly, assembly and replacement very troublesome, time-consuming and labor-intensive.

SUMMARY OF THE INVENTION

In view of the deficiencies of the background technology, the technical problem to be solved by the present invention is to provide a retractor structure with simple structure and reasonable design, which can conveniently realize the disassembly and assembly of the retractor and the replacement of the installation belt.

For this reason, the utility model adopts the following scheme to realize:

A retractor that is easy to disassemble and assemble includes an installation frame, a tape winding shaft and a coil spring, and is characterized in that: the installation frame includes a first installation part and a second installation part, and the coil spring is arranged at one of the first installation parts. One end of the tape winding shaft is rotatably arranged on the first mounting part and connected with the coil spring, and the second mounting part is provided with an arc for the other end of the tape winding shaft to be rotatably mounted. The first mounting part and the second mounting part are hinged together, a first connecting part is extended on one side of the first mounting part, and a second connecting part is extended on one side of the second mounting part A connecting part, the first connecting part and the second connecting part are detachably connected together.

It also includes a connecting bolt, the first connecting part is provided with a first threaded hole, the second connecting part is provided with a connecting hole matched with the first threaded hole, and the connecting bolt passes through the connection and screwed with the first threaded hole.

It also includes a connecting bolt, a slot is opened on one side of the first connecting part, an inserting part that can be inserted into the slot is arranged on the second connecting part, and the first connecting part is in the slot. The upper and lower sides are provided with second threaded holes, the insertion part is provided with through holes matched with the second threaded holes, and the connecting bolts pass through the through holes and are screwed on the two second threaded holes on the hole.

By adopting the above technical scheme, the utility model has the advantages of simple structure and reasonable design, which can realize large-scale production; because the mounting frame is designed as the first mounting part and the second mounting part that are hingedly connected, when the retractor needs to be replaced, it is safe to When belting, the first and second installation parts can be opened, so that the side of the winding shaft away from the coil spring is exposed, and then the whole belt can be taken out from this side, and the entire retractor does not need to be disassembled and assembled, which effectively improves the safety. The replacement efficiency of the belt is more convenient to operate.

Description of drawings

The utility model has the following accompanying drawings:

FIG. 2 is a cross-sectional view of the slot and the insertion part of the present invention when they are matched.

Detailed ways

As shown in the figure, the retractor for easy disassembly and assembly disclosed by the present utility model includes an installation frame, a tape winding shaft 3 and a coil spring 1, the installation frame includes a first installation part 2 and a second installation part 5, and the coil spring 1 is provided with On one side of the first mounting portion 2, one end of the tape winding shaft 3 is rotatably arranged on the first mounting portion 2 and is connected with the coil spring 1, and the second mounting portion 5 is provided with the other end of the tape winding shaft for rotation. The arc-shaped hole 10 for installation, the first installation part 2 and the second installation part 5 are hinged together by the connecting arm 4, the first installation part 2 is provided with a first connection part 8 extending from one side, and the second installation part 5 A second connecting portion 6 is extended on one side, and the first connecting portion 8 and the second connecting portion 6 are detachably connected together. Specifically, it also includes connecting bolts, the first connecting portion 8 is provided with a first threaded hole 9 , the second connecting portion 6 is provided with a connecting hole 7 that matches the first threaded hole 9 , and the connecting bolt passes through the connecting hole 7 It is screwed with the first threaded hole 9, and the first and second installation parts can be separated by removing the connecting bolt. In addition to the above connection structure, a slot 11 is opened on one side of the first connection part 8 , an insertion part 12 which can be inserted into the slot 11 is provided on the second connection part 6 , and the first connection part 8 is located on the side of the slot 11 . The upper and lower sides are provided with second threaded holes 13 , the insertion portion 12 is provided with through holes 14 matched with the second threaded holes 13 , and the connecting bolts pass through the through holes 14 and are screwed on the two second threaded holes 13 .

The retractor of the present invention, which is easy to disassemble and assemble, has a simple structure and a reasonable design. Since the first installation part 2 and the second installation part 5 are hingedly connected to the installation frame, when the retractor needs to replace the seat belt , the first and second installation parts can be opened, so that the side of the winding shaft 3 away from the coil spring 1 is exposed, and then the whole belt can be taken out from this side, and the entire retractor does not need to be disassembled and assembled, which effectively improves the safety. The replacement efficiency of the belt is more convenient to operate.
