Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically to a bolt that effectively prevents it from falling off. Background Technology

[0002] A bolt is a mechanical part consisting of a head and a shank (a cylinder with external threads). It is a cylindrical threaded fastener fitted with a nut. Bolts and nuts are used to fasten two parts with through holes.

[0003] Patent document CN213270669U discloses a bolt for preventing nuts from falling off. It specifies that the bolt includes a bolt base, a metal washer at the upper end of the bolt base, an anti-displacement mechanism on the outer surface of the upper end of the metal washer, a bolt shank at the middle of the upper end of the bolt base, and an anti-fall-off mechanism on the outer wall of the bolt shank. This bolt for preventing nuts from falling off, equipped with both an anti-fall-off mechanism and an anti-displacement mechanism, can prevent the nut from falling off the bolt during use and also prevent liquid from entering the internal thread groove of the nut from the bolt shank, thus preventing corrosion of the internal thread groove. This is beneficial for user convenience. The anti-displacement mechanism can buffer the external force on the bolt during installation, and the wear-resistant and anti-slip pad can improve the bolt's tightness, preventing displacement under external force, thus improving the bolt's usability and bringing better application prospects.

[0004] However, one of the main considerations in the aforementioned published documents is to improve the stability of the nut and prevent the bolt from falling off by using adhesive pads and anti-slip pads. However, adhesive pads are prone to failure after long-term use, and anti-slip pads only play a role in preventing slippage and lack elastic positioning components for the nut, which can still cause the nut to loosen and the bolt to fall off.

[0005] In view of this, it is necessary to develop a bolt that can effectively prevent the nut from falling off, thereby positioning the nut so that it will not loosen or fall off even after long-term use. Utility Model Content

[0006] The purpose of this invention is to provide a bolt that effectively prevents it from falling off, thereby solving the technical problem mentioned in the background art, which is that the lack of an elastic positioning component for the nut causes the nut to loosen and the bolt to fall off.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bolt that effectively prevents detachment, comprising: a bolt body, wherein a mounting hole is provided at the top of the bolt body, an elastic mounting component is installed inside the mounting hole, a positioning component is installed at the top of the elastic mounting component, the positioning component includes a fixing plate and a positioning plate, the fixing plate is installed on the top of the elastic mounting component, and the positioning plates are symmetrically installed on the bottom sides of the fixing plate.

[0008] Preferably, a fixing screw is installed through the top of the fixing plate.

[0009] Preferably, the elastic mounting assembly includes a connecting spring, a connecting shaft, and a mounting head. The connecting spring is mounted inside the mounting hole, the connecting shaft is mounted on the top of the connecting spring and is located inside the mounting hole, and the mounting head is mounted on the top of the connecting shaft and is located on the top of the bolt body.

[0010] Preferably, the top of the mounting head has a mounting groove, and the mounting groove is connected to the fixing plate.

[0011] Preferably, a threaded hole is provided on the bottom inner wall of the mounting groove, and the threaded hole is threadedly connected to the fixing screw.

[0012] Preferably, a nut is installed on the outer thread of the bolt body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the fixing plate in the positioning component is installed on the top of the elastic mounting by fixing screws, so that the positioning plate is installed above the nut through the elastic mounting component. When the fixing plate is installed on the top of the elastic mounting component, the bottom of the mounting head is clamped by a tool and the mounting head is pulled upward, thereby lifting the connecting axis upward. The connecting spring in the elastic mounting component is stretched, which generates a downward pulling force, thereby driving the positioning plate to move downward and apply pressure to the nut on the outside of the bolt body, so that the nut is stably positioned on the outside of the bolt body and prevents the nut from loosening and causing the bolt body to fall off.

[0023] Please see Figure 1 and Figure 3 A type of bolt that effectively prevents it from falling off;

[0024] Includes: bolt body 1 and positioning assembly. The bolt body 1 has a mounting hole 3 at its top end. An elastic mounting assembly is installed inside the mounting hole 3. A positioning assembly is installed at the top end of the elastic mounting assembly. The positioning assembly includes a fixing plate 9 and a positioning plate 11. The fixing plate 9 is installed on the top of the elastic mounting assembly. The positioning plate 11 is symmetrically installed on the bottom sides of the fixing plate 9. A fixing screw 10 is installed through the top of the fixing plate 9.

[0025] The bolt body 1 is a fastener that works in conjunction with the nut 2. The bolt body 1 provides a position for the mounting hole 3, which is used to install the elastic mounting component. The top of the elastic mounting component provides a position for the positioning component. The fixing plate 9 in the positioning component is installed on top of the elastic mounting component by fixing screws 10, so that the positioning plate 11 is installed above the nut 2 through the elastic mounting component. When the fixing plate 9 is installed on top of the elastic mounting component, the elastic mounting component is first pulled upward with a tool. When pulled, the connecting spring 4 in the elastic mounting component is stretched, which generates a downward pulling force, thereby driving the positioning plate 11 to move downward and apply pressure to the nut 2 on the outside of the bolt body 1, so that the nut 2 is stably positioned on the outside of the bolt body 1, preventing the nut 2 from loosening and causing the bolt body 1 to fall off.

[0026] Please see Figure 1 , Figure 2 and Figure 4 A type of bolt that effectively prevents it from falling off;

[0027] The device includes a flexible mounting assembly, which comprises a connecting spring 4, a connecting shaft 5, and a mounting head 6. The connecting spring 4 is installed inside the mounting hole 3, the connecting shaft 5 is installed on the top of the connecting spring 4 and is located inside the mounting hole 3, the mounting head 6 is installed on the top of the connecting shaft 5 and is located on the top of the bolt body 1, the top of the mounting head 6 has a mounting groove 7 and is connected to the fixing plate 9, the bottom inner wall of the mounting groove 7 has a threaded hole 8 and is threadedly connected to the fixing screw 10, and a nut 2 is threadedly installed on the outer side of the bolt body 1.

[0028] When the worker pulls the elastic mounting component, the bottom of the mounting head 6 is held by a tool and the mounting head 6 is pulled upward, thereby lifting the connecting shaft 5 upward. The stretched connecting spring 4 provides pressure on the nut 2, so that the nut 2 will not loosen or rotate outward. The mounting head 6 provides a position for the installation of the mounting groove 7. The interior of the mounting groove 7 provides space for fixing the fixing plate 9. The threaded hole 8 provides space for fixing the fixing screw 10. The bottom end of the fixing screw 10 passes through the bottom of the fixing plate 9 through the thread and enters the threaded hole 8 to fix the fixing plate 9.

[0029] The working principle is as follows: First, the nut 2 is rotated to the outside of the bolt body 1. The operator pulls the connecting shaft 5 outward through the mounting head 6. At this time, the connecting spring 4 connected to the connecting shaft 5 is stretched. Then, the fixing plate 9 is fixed inside the mounting groove 7 by the fixing screw 10, so that the positioning plate 11 is located above the nut 2. Then, the mounting head 6 is released and the connecting spring 4 is moved downward, so that the positioning plate 11 applies a downward pulling force to the nut 2, so that the nut 2 is stably located on the outside of the bolt body 1.
