The bolt is connected to the self-locking nut and the shaped washer. The shaped washer is connected to one end near the bolt head, and the self-locking nut is connected to the other end. Both connecting rods are provided with retaining grooves for limiting movement. This utility model, by setting up the shaped washer, the self-locking nut, and the retaining grooves, limits the movement of the shaped washer and the self-locking nut through the retaining grooves, thereby limiting both ends of the bolt and preventing the bolt from loosening.

[0004] Based on the search of the aforementioned patents and in conjunction with existing anti-loosening devices, it was found that although the aforementioned anti-loosening devices can limit the bolts by using irregularly shaped washers, the washers need to be moved to make them fit tightly against the bolts each time. With prolonged use, the washers are prone to detaching from the bolts, which reduces the limiting effect on the bolts and makes the bolts prone to loosening, thus reducing their practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a connection anti-loosening device for a tire blowout emergency safety device, in order to solve the problem mentioned in the background art that, although the existing anti-loosening devices can limit the bolts through the irregularly shaped shims, the shims need to be moved to make them fit tightly against the bolts each time. After long-term use, the shims are prone to detach from the bolts, the limiting effect on the bolts will be reduced, and the bolts will be prone to loosening, thus reducing their practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tire blowout emergency safety device connection anti-loosening device, comprising an emergency support plate and an anti-loosening component. The anti-loosening component includes a notch on one side of the emergency support plate, a screw rod disposed in the notch, a connecting plate fixedly connected to one end of the screw rod, a connecting port on one side of the emergency support plate, a threaded hole on one side of the connecting port, a cavity on the inner wall of the connecting plate, a bidirectional lead screw connected to the inner wall of the cavity, a drive plate connected to both sides of the bidirectional lead screw, an anti-loosening rod fixedly connected to one side of the drive plate, a plurality of anti-loosening holes arranged circumferentially on the inner wall of the notch, an auxiliary component for improving the anti-loosening effect, and a drive component for rotating the bidirectional lead screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting up an emergency support plate and anti-loosening components, the emergency support plate can be connected and fixed to the car wheel hub by screwing the screw into the threaded hole. Rotating the drive shaft can drive the active bevel gear to rotate, which in turn controls the rotation of the driven bevel gear and the double-acting screw. This allows the two drive plates to drive the anti-loosening rod to insert into the anti-loosening hole, which can lock the connecting plate and the screw, preventing the screw from rotating and thus preventing loosening. This ensures the connection stability of the emergency support plate and prevents it from detaching from the wheel hub, thereby greatly improving the practicality of the device.

[0014] 2. With the addition of auxiliary components, the limiting plate can be inserted into the connection port. The protrusion, under the pressure of the connection port, can drive the slide rod to compress the spring and deform it. When the limiting plate is in contact with the inner wall of the connection port, the spring returns to its original position and pushes the protrusion into the slot, which can perform secondary limiting and fixing of the screw, thereby further improving the anti-loosening effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5This utility model provides a technical solution: a tire blowout emergency safety device connection anti-loosening device, including an emergency support plate 1 and an anti-loosening component. The anti-loosening component includes a notch 21 on one side of the emergency support plate 1, a screw 22 disposed in the notch 21, a connecting plate 23 fixedly connected to one end of the screw 22, a connecting port 24 on one side of the emergency support plate 1, a threaded hole 25 on one side of the connecting port 24, a cavity 26 on the inner wall of the connecting plate 23, a bidirectional lead screw 27 connected to the inner wall of the cavity 26, a drive plate 28 connected to both sides of the bidirectional lead screw 27, an anti-loosening rod 29 fixedly connected to one side of the drive plate 28, and a connection plate 25 on one side of the emergency support plate 1. The recess 21 has multiple anti-loosening holes 30 arranged in a circular pattern on its inner wall, auxiliary components for improving the anti-loosening effect, and a drive component for rotating the bidirectional lead screw 27. The bidirectional lead screw 27 is screwed to the drive plate 28, the anti-loosening rod 29 is inserted into the anti-loosening holes 30, and the bidirectional lead screw 27 is rotatably connected to the inner wall of the cavity 26. The screw 22 is screwed to the threaded hole 25, and the screw 22 can be inserted into the threaded hole 25. By rotating the connecting plate 23, the screw 22 can be driven to screw into the threaded hole 25, which can fix the emergency support plate 1 to the hub. The rotation of the bidirectional lead screw 27 can cause the two drive plates 28 to move in opposite directions, thereby controlling the anti-loosening rod 29 to engage. The anti-loosening hole 30 can hold the connecting plate 23, thereby preventing the screw 22 from rotating and improving the anti-loosening performance. The driving component includes a driven bevel gear 41 fixedly connected to the outside of the double-acting screw 27, a driving bevel gear 42 connected to the driven bevel gear 41, and a drive shaft 43 fixedly connected to the driving bevel gear 42. The drive shaft 43 is rotatably connected to the connecting plate 23. The driving bevel gear 42 meshes with the driven bevel gear 41. The rotation of the drive shaft 43 can drive the driving bevel gear 42 to rotate, which in turn drives the driven bevel gear 41 to rotate, thus facilitating the rotation of the double-acting screw 27 and facilitating the control of the anti-loosening rod 29. The drive shaft 43 is fixedly connected to a rotating plate 61 at one end, and a handle 62 is fixedly connected to one side of the rotating plate 61. The handle 62 can be used to drive the rotating plate 61 to rotate, which in turn can drive the drive shaft 43 to rotate, and thus indirectly control the movement of the anti-loosening rod 29, which facilitates the fixing or releasing of the screw 22. Guide grooves 71 are respectively opened on both sides of the cavity 26, and guide blocks 72 are slidably connected in the guide grooves 71. The guide blocks 72 are fixedly connected to the drive plate 28, and the drive plate 28 can drive the guide blocks 72 to move synchronously. The guide blocks 72 can guide the drive plate 28 to prevent the drive plate 28 from rotating synchronously with the bidirectional lead screw 27.

[0023] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5The auxiliary components include a limiting plate 31 fixedly connected to the outside of the screw 22, grooves 32 respectively opened on both sides of the limiting plate 31, a sliding rod 33 disposed in the groove 32, a spring 34 fixedly connected to one end of the sliding rod 33, a protrusion 35 fixedly connected to the other end of the sliding rod 33, and a plurality of slots 36 arranged circumferentially on the inner wall of the connection port 24. The sliding rod 33 is slidably connected to the groove 32. The connection port 24 can squeeze the protrusion 35 to make it slide the sliding rod 33 in the groove 32, and then squeeze the spring 34 to deform it. The limiting plate 31 can be inserted into the connection port. Inside the groove 24, the protrusion 35 contacts the inner wall of the connection port 24. At this time, the protrusion 35 contacts the slot 36. The spring 34 can push the protrusion 35 into the slot 36, which can improve the limiting performance of the screw 22 and further improve the anti-loosening performance. The groove 32 has anti-rotation grooves 51 on both sides. Anti-rotation blocks 52 are slidably connected in the anti-rotation grooves 51. The anti-rotation blocks 52 are fixedly connected to the slide rod 33. The slide rod 33 can drive the anti-rotation blocks 52 to slide in the anti-rotation grooves 51. The anti-rotation blocks 52 can prevent the slide rod 33 from rotating, thereby preventing the spring 34 from rotating and being damaged.

[0024] Working principle: During operation, the emergency support plate 1 is wrapped around the wheel hub once, and then the screw 22 is inserted into the threaded hole 25. By rotating the connecting plate 23, the screw 22 rotates, causing it to screw into the threaded hole 25. At the same time, the limiting plate 31 is inserted into the connecting port 24. The connecting port 24 can squeeze the protrusion 35, causing it to move the slide rod 33. The movement of the slide rod 33 can squeeze the spring 34, causing it to deform. When the connecting plate 23 can no longer rotate, the limiting plate 31 is in contact with the inner wall of the connecting port 24. The spring 34 then resets, causing the protrusion 35 to reset, so that the protrusion 35 is locked into the slot 36, which can limit the screw 22. Then, the handle 62 can be driven to rotate the rotating plate 61. Rotation of 61 drives the drive shaft 43 to rotate, which in turn drives the active bevel gear 42 to rotate. The active bevel gear 42 then drives the driven bevel gear 41 to rotate, which in turn drives the double-acting screw 27 to rotate. The double-acting screw 27 then drives the two drive plates 28 to move to both sides. The drive plates 28 then drive the anti-loosening rod 29 to move. The anti-loosening rod 29 can then be inserted into the anti-loosening hole 30, thereby locking the connecting plate 23 and preventing it from rotating. This, in turn, prevents the screw 22 from rotating, greatly improving the anti-loosening effect. The above is the working process of the entire device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
