Description

Technical Field

[0001] The utility model relates to the technical field of safety belt fixing, in particular to a hexagonal stud for a car seat safety belt. Background Art

[0002] A car seat is a seat used when riding in a vehicle. It provides drivers and passengers with an easy-to-operate, comfortable, and safe driving and riding position. However, a car seat must also be equipped with a seat belt. The main function of a seat belt is to reduce the possibility of death or serious injury in a traffic collision by reducing the force of a secondary impact with an internal impact hazard. It also ensures the maximum effectiveness of the airbag by correctly positioning the occupants and preventing them from being ejected from the vehicle or the vehicle rolling over in a collision.

[0003] During installation, existing car seat belts typically use hexagonal studs to secure the belt's connecting plate to the vehicle's proper location, and then the belt is threaded through the connecting plate to complete the installation. However, securing the connecting plate with the hexagonal studs, especially when the seat belt is frequently pulled and shaken, can affect both the connecting plate and the hexagonal studs. Over time, this can cause the hexagonal studs to loosen, compromising the device's securement. Utility Model Content

[0004] The main purpose of the utility model is to provide a hexagonal stud for a car seat safety belt, which can effectively solve the problem of poor stability of the hexagonal stud.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A car seat belt hexagonal stud includes a hexagonal nut, a limiting device is installed on the outer surface of the hexagonal nut, auxiliary fixing plates are fixedly installed on the lower left and right ends of the limiting device, two fixing screws are installed on the upper ends of the two auxiliary fixing plates, and a mounting device is installed on the lower end of the hexagonal nut.

[0007] Preferably, the hexagonal nut has a rotation groove at its upper end, a washer is fixedly mounted at its lower end, and a threaded column is mounted on both the hexagonal nut and the washer. The surfaces of the hexagonal nut, washer, and threaded column are all plated with zinc-nickel alloy to improve the corrosion resistance of the device.

[0008] Preferably, the limiting device includes a limiting seat, a limiting slot is defined at the lower end of the limiting seat, and a nut retaining slot is defined at the upper end of the limiting seat, wherein the limiting seat is mounted on the outer surface of the hexagonal nut via the nut retaining slot. The connecting plate is limited and clamped by the limiting slot on the limiting seat, and the hexagonal nut is clamped by the nut retaining slot. The limiting seat is then fixed in place by fixing screws on the auxiliary fixing plate, thereby auxiliary fixing the connecting plate and preventing the connecting plate from being pulled and loosened when the safety belt is pulled.

[0009] Preferably, the mounting device includes a connecting plate having a mounting hole at the rear end of the connecting plate's upper end and a seat belt receptacle at the front end of the connecting plate. The connecting plate is inserted through the mounting hole and mounted on the outer surface of the threaded post. The threaded post is screwed into the screw hole through the screw groove on the hexagonal nut, thereby securing the connecting plate in a suitable position on the vehicle. The seat belt can then be passed through the seat belt receptacle through the connecting plate to install the seat belt.

[0010] Preferably, the limiting groove is in a dovetail shape.

[0011] Preferably, the mounting hole is consistent in size with the threaded column and their positions correspond to each other, and the size of the gasket is larger than the mounting hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When installing the car seat belt, first insert the threaded column at the lower end of the hexagonal nut into the mounting hole on the connecting plate on the mounting device, then align the threaded column with the mounting screw hole, and then screw the threaded column into the screw hole through the rotating groove on the hexagonal nut, thereby fixing the connecting plate in a suitable position on the vehicle. Then, pass the seat belt through the seat belt socket through the connecting plate to install the seat belt. The surfaces of the hexagonal nut, gasket and threaded column are all zinc-nickel alloy-plated to improve the corrosion resistance of the device.

[0014] 2. After the threaded column is installed, align the hexagonal nut with the limiting seat on the limiting device. At this time, the limiting groove on the limiting seat limits and clamps the connecting plate, and the nut slot clamps the hexagonal nut. Then fix the limiting seat with the fixing screws on the auxiliary fixing plate, so as to assist in fixing the connecting plate and prevent the connecting plate from being driven by the safety belt when pulled, causing it to loosen.

[0023] like Figure 1-4 As shown, a hexagonal stud for a car seat belt includes a hexagonal nut 1. A limiting device 2 is installed on the outer surface of the hexagonal nut 1. Auxiliary fixing plates 4 are fixedly installed on the lower left and right ends of the limiting device 2. Two fixing screws 5 are installed on the upper ends of the two auxiliary fixing plates 4. A mounting device 3 is installed on the lower end of the hexagonal nut 1.

[0024] The upper end of the hexagonal nut 1 is provided with a rotation groove 10, the lower end of the hexagonal nut 1 is fixedly mounted with a washer 11, and the lower ends of the hexagonal nut 1 and the washer 11 are jointly mounted with a threaded column 12. The surfaces of the hexagonal nut 1, washer 11 and threaded column 12 are all plated with zinc-nickel alloy to improve the corrosion resistance of the device.

[0025] The limiting device 2 includes a limiting seat 20 with a limiting slot 21 defined at its lower end and a nut retaining slot 22 defined at its upper end. The limiting seat 20 is mounted on the outer surface of the hexagonal nut 1 via the nut retaining slot 22; the limiting slot 21 is dovetail-shaped. The limiting slot 21 on the limiting seat 20 secures the connecting plate 30, while the nut retaining slot 22 secures the hexagonal nut 1. The limiting seat 20 is then secured using the fixing screws 5 on the auxiliary fixing plate 4, thereby assisting in securing the connecting plate 30 and the hexagonal nut 1. This prevents the connecting plate 30 and the hexagonal nut 1 from loosening due to the seat belt being pulled.

[0026] The mounting device 3 includes a connecting plate 30 with a mounting hole 31 at the rear end and a seatbelt insertion opening 32 at the front end. The connecting plate 30 is inserted through the mounting hole 31 and mounted on the outer surface of the threaded post 12. The mounting hole 31 is the same size as the threaded post 12 and is positioned vertically correspondingly. The washer 11 is larger than the mounting hole 31. The threaded post 12 is screwed into the screw hole through the screw groove 10 on the hexagonal nut 1, thereby securing the connecting plate 30 in the desired position on the vehicle. The seatbelt can then be installed by passing the seatbelt through the seatbelt insertion opening 32 through the connecting plate 30.

[0027] It should be noted that the present invention is a hexagonal stud for a car seat safety belt. First, insert the threaded column 12 at the lower end of the hexagonal nut 1 into the mounting hole 31 on the connecting plate 30 on the mounting device 3, then align the threaded column 12 with the mounting screw hole, then screw the threaded column 12 into the screw hole through the rotating groove 10 on the hexagonal nut 1, thereby fixing the connecting plate 30 in a suitable position on the vehicle, and then pass the seat belt through the seat belt socket 32 through the connecting plate 30 to install the seat belt, and the hexagonal nut 1 and the gasket are fixed to the seat belt. The surfaces of 11 and the threaded column 12 are both plated with zinc-nickel alloy to improve the corrosion resistance of the device. Then, the hexagonal nut 1 is aligned with the limiting seat 20 on the limiting device 2. At this time, the limiting groove 21 on the limiting seat 20 limits and clamps the connecting plate 30, and the nut clamping groove 22 clamps the hexagonal nut 1. Then, the limiting seat 20 is fixed by the fixing screw 5 on the auxiliary fixing plate 4, so that the connecting plate 30 and the hexagonal nut 1 can be auxiliary fixed to prevent the safety belt from driving the connecting plate 30 and the hexagonal nut 1 when being pulled, causing them to loosen.
