Description

Technical Field

[0001] This utility model relates to the field of seat belt technology, specifically to a fixing bracket for fixing a three-point seat belt. Background Technology

[0002] Three-point seat belts are the most common safety device in cars. They consist of a shoulder strap that crosses the chest and a leg strap that secures the waist. They are connected by a single buckle to form a triangular fixing structure. When a vehicle collides or brakes suddenly, the inertial reel of the seat belt senses an acceleration exceeding a threshold and triggers the locking mechanism to instantly fix the webbing and prevent the occupant from lurching forward. The seat belt is mainly secured by the reel and the buckle. The driver manually pulls the buckle on the outside of the seat belt and crosses the seat belt across the chest and waist, then inserts the buckle into the lock to lock it in place.

[0003] CN210502597U discloses a car seatbelt fixing bracket, including a connecting block and a base. A seatbelt lock seat is placed on the top of the base. Support rods are fixedly connected to both sides of the top of the base. A threaded rod is threaded through the axis of each support rod. A handwheel is fixedly connected to one end of the threaded rod, and a clamping plate is fixedly connected to the end of the threaded rod away from the handwheel. The clamping plate contacts the seatbelt lock seat. A through groove is formed in the inner cavity of the connecting block, and a seatbelt is movably connected to the front of the connecting block through the through groove. A connecting rod is fixedly connected to the bottom of the connecting block. This utility model, through the coordinated use of the base, seatbelt lock seat, support rod, threaded rod, handwheel, and clamping plate, has the advantage of fixing the seatbelt lock seat, solving the problem that existing seatbelt interfaces are often loose, making it difficult for the seatbelt lock head to engage with the seatbelt lock seat, thus wasting unnecessary time.

[0004] While the existing technology CN210502597U has many advantages in use, it still has the following problems: its protection of the latch is not perfect. When the driver eats or rests inside the vehicle, food residue may fall into the latch, causing it to jam and affecting the smoothness of the latch inserting into the latch. Utility Model Content

[0005] To address the problems in the prior art, this utility model provides a fixing bracket for securing a three-point safety belt.

[0006] The technical solution adopted by this utility model to solve its technical problem is a fixing bracket for fixing a three-point safety belt, including a fixing rod, a cover plate and a bearing seat. A buckle is installed on one side of the upper outer wall of the fixing rod. Bearing seats are provided on both sides of the outer wall of the buckle. A sleeve is interference-fitted inside the bearing seat. A movable groove is opened inside the sleeve. A cover plate is provided on one side of the upper outer wall of the buckle. A rotating shaft is rotatably installed on both sides of the outer wall of the cover plate. A support member is installed on the outer wall of one end of the rotating shaft. A movable rod is provided on the lower outer wall of the support member.

[0007] By adopting the above technical solution, the cover plate can rotate circumferentially through the bearing seat and the rotating shaft, and the rotation range of the cover plate is controlled by the movable rod and the sleeve. The cover plate can block the latch, prevent foreign objects or food residue from falling into the latch, ensure the cleanliness of the latch, and ensure the smooth insertion of the buckle into the latch.

[0008] Specifically, the fixing rod adopts a curved shape design, and a fixing hole is opened on one side of the outer wall of the fixing rod.

[0009] By adopting the above technical solution, the curved fixing rod can fit the interior structure of the vehicle, avoiding taking up too much space, and is directly connected to the fixed position of the vehicle body through the fixing hole by the external fixing screw, ensuring the stability of the bracket and the buckle in use.

[0010] Specifically, the outer wall of the bearing housing is equipped with a circular array of connectors, and the bearing housing is connected to the outer wall of the latch by screws through the connectors.

[0011] By adopting the above technical solution, the connector ensures the connection strength between the bearing housing and the latch, ensures the stability of the bearing housing in the working position outside the latch, and facilitates the disassembly and maintenance of the bearing housing.

[0012] Specifically, the size of the cover plate is adapted to the size of the upper end face of the latch, and a sealing gasket is adhered and fixed to the lower outer wall of the cover plate, and the sealing gasket is in contact with the upper end face of the cover plate.

[0013] By adopting the above technical solution, the cover plate and sealing gasket effectively prevent dust or liquid from entering the lock, avoiding the lock from being unable to lock or unlock properly due to foreign objects getting stuck, extending the service life of the lock, and ensuring the smooth insertion of subsequent clips into the lock.

[0014] Specifically, the size of the movable rod is smaller than the inner wall size of the movable groove. The movable rod is located inside the movable groove, and a spring is provided on the outer wall of the movable rod. The spring is located inside the movable groove, and the movable rod is elastically connected to the inner wall of the movable groove through the spring.

[0015] By adopting the above technical solution, the spring force pushes the movable rod to ensure the stability of the movable rod's position inside the sleeve. By pulling the movable rod, the position of the cover plate on the upper end face of the latch can be kept relatively stable, ensuring the continuous coverage of the latch by the cover plate.

[0016] Specifically, the support member has bolts inside, and the bolts are threaded through the support member and connected to the inside of the movable rod.

[0017] By adopting the above technical solution, the bolts ensure the connection strength between the support and the movable rod, and ensure that the movement of the movable rod can drive the cover plate to move synchronously.

[0018] Specifically, limit blocks are installed on both sides of the upper outer wall of the latch, and the cover plate is in contact with the outer wall of the limit blocks.

[0019] By adopting the above technical solution, the limiting block restricts the range of motion of the cover plate, ensuring its accurate positioning in the closed state and preventing the lock from failing due to cover plate displacement. When the lock needs to be used, the driver manually moves the cover plate, which rotates through the connecting rod, sleeve, bearing seat and rotating shaft, causing the cover plate to rotate and move to the outside of the lock. The spring force pulls the cover plate to contact and rub against the outer wall of the lock, ensuring the stability of the cover plate's position. Afterwards, the driver manually pulls the cover plate back to its original position, and the limiting block restricts the position of the cover plate, keeping the cover plate stable on the upper surface of the lock.

[0020] The beneficial effects of this utility model are:

[0021] (1) The fixing bracket for fixing a three-point safety belt described in this utility model can cover the buckle, prevent foreign objects or food residue from falling into the buckle, ensure the cleanliness of the buckle, and ensure the smooth insertion of the buckle into the buckle.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a fixing bracket for fixing a three-point safety belt, comprising a fixing rod 1, a cover plate 2, and a bearing seat 3. A buckle 11 is installed on one side of the upper outer wall of the fixing rod 1, and bearing seats 3 are provided on both sides of the outer wall of the buckle 11. A sleeve 32 is interference-fitted inside the bearing seat 3, and a movable groove 33 is opened inside the sleeve 32. A cover plate 2 is provided on one side of the upper outer wall of the buckle 11, and a rotating shaft 21 is rotatably installed on both sides of the outer wall of the cover plate 2. A support member 22 is installed on the outer wall of one end of the rotating shaft 21, and a movable rod 23 is provided on the lower outer wall of the support member 22.

[0030] During use, the cover plate 2 can rotate circumferentially through the bearing seat 3 and the rotating shaft 21, and the rotation range of the cover plate 2 is controlled by the movable rod 23 and the sleeve 32. The cover plate 2 covers the latch 11 to prevent foreign objects or food residue from falling into the latch 11, ensuring the cleanliness of the inside of the latch 11 and ensuring the smooth insertion of the buckle into the latch 11.

[0031] To fix the usage location, for example, such as Figure 1 As shown, the fixing rod 1 adopts a curved shape design, and a fixing hole is opened on one side of the outer wall of the fixing rod 1.

[0032] When in use, the curved fixing rod 1 can fit the interior structure of the vehicle to avoid taking up too much space, and it is directly connected to the fixed position of the vehicle body through the fixing hole by the external fixing screw, ensuring the stability of the bracket and the buckle 11 in use.

[0033] To fix the usage location, for example, such as Figure 4 As shown, the outer wall of the bearing housing 3 is equipped with a circular array of connectors 31, and the bearing housing 3 is connected to the outer wall of the latch 11 by screws through the connectors 31.

[0034] During use, the connector 31 ensures the connection strength between the bearing housing 3 and the latch 11, ensures the stability of the bearing housing 3 in the working position outside the latch 11, and facilitates the disassembly and maintenance of the bearing housing 3.

[0035] For the purpose of shielding and protection, for example, such as Figure 2 As shown, the size of the cover plate 2 is adapted to the size of the upper end face of the latch 11. A sealing gasket is adhered and fixed to the lower outer wall of the cover plate 2, and the sealing gasket is in contact with the upper end face of the cover plate 2.

[0036] During use, the cover plate 2, together with the sealing gasket, effectively prevents dust or liquid from entering the lock 11, avoiding the lock 11 from being unable to lock or unlock properly due to foreign objects getting stuck, extending the service life of the lock 11, and ensuring the smooth insertion of subsequent clips into the lock 11.

[0037] To maintain the usage location, for example, such as Figure 4 As shown, the size of the movable rod 23 is smaller than the inner wall size of the movable groove 33. The movable rod 23 is located inside the movable groove 33. A spring 25 is provided on the outer wall of the movable rod 23. The spring 25 is located inside the movable groove 33. The movable rod 23 is elastically connected to the inner wall of the movable groove 33 through the spring 25.

[0038] During use, the spring 25 pushes the movable rod 23 to ensure the stability of the movable rod 23 inside the sleeve 32. By pulling the movable rod 23, the position of the cover plate 2 on the upper surface of the latch 11 can be kept relatively stable, ensuring the continuous blocking of the latch 11 by the cover plate 2.

[0039] For fixed connections, for example, such as Figure 3 As shown, a bolt 24 is provided inside the support member 22, and the bolt 24 passes through the support member 22 and is threadedly connected to the inside of the movable rod 23.

[0040] During use, bolt 24 ensures the connection strength between support 22 and movable rod 23, and ensures that the movement of movable rod 23 can drive cover plate 2 to move synchronously.

[0041] To restrict the location of use, for example, such as Figure 1 As shown, limit blocks 12 are installed on both sides of the upper outer wall of the latch 11, and the cover plate 2 is in contact with the outer wall of the limit block 12.

[0042] During use, the limiting block 12 restricts the range of motion of the cover plate 2 to ensure its accurate positioning in the closed state and prevent the latch 11 from failing due to the displacement of the cover plate 2. When the latch 11 needs to be used, the driver manually moves the cover plate 2. The cover plate 2 rotates through the connecting rod, sleeve 32, bearing seat 3 and rotating shaft 21, causing the cover plate 2 to rotate and move to the outside of the latch 11. The spring 25 pulls the cover plate 2 to contact and rub against the outer wall of the latch 11 to ensure the stability of the position of the cover plate 2. After that, the driver manually pulls the cover plate 2 to reset it. The limiting block 12 restricts the position of the cover plate 2 to keep the cover plate 2 in a stable position on the upper surface of the latch 11.

[0043] In use, the curved fixing rod 1 is fitted to the interior structure of the vehicle, and the external fixing screw passes through the fixing hole on one side of the outer wall of the fixing rod 1 to connect to the fixed position of the vehicle body.

[0044] The driver manually moves the cover plate 2, which rotates through the pivot 21, the movable rod 23, the sleeve 32 and the bearing seat 3. During this process, due to the elastic connection between the spring 25 and the inner wall of the movable groove 33, the spring 25 pulls the cover plate 2 to contact and rub against the outer wall of the buckle 11, ensuring that the cover plate 2 is stable when it rotates and moves to the outside of the buckle 11, and that the seat belt buckle can be inserted into the buckle 11 for fixation.

[0045] After using the latch 11, the driver manually pulls the cover plate 2 to reset it. When the cover plate 2 returns to the position of the upper end of the latch 11, the limit block 12 restricts the position of the cover plate 2 again.
