Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety belts, in particular to a safety belt retractor with an emergency locking effect. Background Art
[0002] The purpose of a car seat belt is to restrain the occupants in a collision and to prevent the occupants from having a secondary collision with the steering wheel and dashboard, or from rushing out of the car and causing death or injury. The car seat belt can also be called a seat belt, which is a type of occupant restraint device. Current seat belts all have an emergency locking function, but the overall structural design is relatively complex.
[0003] For example, an emergency locking seat belt with application number 202320965400.0 is provided with a spiral spring, a sleeve block, a strip spring, a connecting block, teeth and an inner toothed disc. When emergency braking is performed, the driver or passenger leans forward and pulls the first webbing, which drives the reel to rotate rapidly. The reel drives the inner toothed disc to rotate rapidly, so the connecting block and the teeth move outward due to the centrifugal force, and are stuck in the inner toothed disc, which brakes the reel and thus brakes the first webbing. An elastic band is provided between the first webbing and the second webbing to play a buffering role, which can prevent the driver and passengers from being strangled during emergency braking. The overall structural design is relatively simple. However, it is difficult for the device to clean the surface of the retracted seat belt. The surface of the seat belt is easily sticky with hair and debris. After long-term stickiness, it is easy to affect the performance of the retractor.
[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a seat belt retractor with an emergency locking effect is proposed. Utility Model Content
[0005] The purpose of the utility model is to provide a seat belt retractor with an emergency locking effect to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a seat belt retractor with emergency locking effect, comprising a retractor body and a mounting seat installed on the upper surface of the retractor body, the upper surface of the mounting seat is fixedly connected with a socket, a cleaning rod is arranged inside the socket, and two sets of locking mechanisms are arranged inside the socket.
[0007] Preferably, the locking mechanism comprises a locking strip arranged inside the holder, the lower surface of the locking strip is fixedly connected to a limiting strip, the inner surface of the holder is provided with a limiting groove, and a fitting mechanism is arranged from the inside of the locking strip to the outside.
[0008] Preferably, the fitting mechanism includes a spring groove opened inside the clamping strip, the interior of the spring groove is fixedly connected to a fitting spring, the interior of the spring groove extends to the outside and is slidably connected to a fitting frame, and the upper surface of the fitting frame is fixedly connected to the lower surface of the cleaning rod.
[0009] Preferably, a laminating roller is rotatably connected to the inner surface of the laminating frame, and an anti-slip block is fixedly connected to one end of the laminating frame.
[0010] Preferably, the upper surface of the clamping seat extends to the inner surface and is slidably connected to a locking rod, and the upper surface of the clamping strip is provided with a clamping hole.
[0011] Preferably, the outer circumferential surface of the locking rod is fixedly connected with a sliding block, and the upper surface of the sliding block is provided with a locking spring.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The utility model is provided with a retractor body, an additional seat, a clamping seat, a brush rod, a clamping mechanism, a clamping strip, a limit strip, a limit groove, a fitting mechanism, a spring groove, a fitting spring, a fitting frame, a fitting roller, and an anti-slipping block. When the retractor body reels the seat belt, the brush rod can clean the debris and dust on the surface of the seat belt. During the cleaning process, the fitting springs in the two sets of fitting mechanisms can make the fitting roller fit the surface of the seat belt to prevent the brush rod from excessively fitting and cleaning, resulting in damage to the surface of the seat belt or the brush rod. The fitting mechanism can achieve a better fitting purpose. The anti-slipping block can prevent the fitting frame from sliding out of the interior of the clamping seat. In addition, the clamping strip inside the clamping seat can be slid out to maintain or replace the brush rod. During the sliding process, the limit strip can slide inside the limit groove to provide a limiting function.
[0014] 2. The utility model provides a locking rod, a card hole, a slider, and a locking spring. When maintaining or replacing the card strip, the locking rod can be pulled upward to make the slider compress the locking spring and allow the locking rod to be separated from the inside of the card hole. After replacement, the locking rod can be inserted into the inside of the card hole in the same way to achieve a better locking function. This design makes it easy to disassemble or fix the card strip. BRIEF DESCRIPTION OF THE DRAWINGS
