Technical Field

[0001] The utility model relates to the field of anti-loosening sealing bolts, and more specifically, to an anti-loosening sealing bolt with good tightness. Background Art

[0002] A bolt is a mechanical part, a cylindrical threaded fastener used with a nut, and is a type of fastener composed of two parts: a head and a threaded cylinder of the screw rod. It needs to cooperate with a nut to be used for fastening and connecting two parts with through holes. Currently, the general measures for preventing the loosening of bolts are through self-locking nuts and filling thread glue in the threaded holes, so that the bolts are more firmly fixed when installed. There is also a type of bolt that adds ratchet-like teeth at the contact area between the head of the nut and the surface of the part to fix the bolt, and this type is non-removable.

[0003] Although the above-mentioned addition of self-locking nuts and thread glue can achieve a certain anti-loosening effect, the anti-loosening effect is weak, and it is more laborious to disassemble the bolts later. When disassembling the non-removable bolts, in order to ensure the integrity of the bolt installation surface, the bolts can only be cut off by a cutting machine. If brute force is used to remove the non-removable bolts, the installation surface will be scratched, bringing a lot of inconvenience to the staff. Summary of the Utility Model

[0004] In view of the problems in the related art, the present utility model proposes an anti-loosening sealing bolt with good tightness to overcome the above-mentioned technical problems existing in the prior related art.

[0005] For this purpose, the specific technical solution adopted by the present utility model is as follows:

[0006] An anti-loosening sealing bolt with good tightness includes a sealing bolt body. An anti-loosening installation component is arranged inside the sealing bolt body, and a sealing installation component is arranged on one side of the anti-loosening installation component.

[0007] In order to achieve the function of anti-loosening installation, the anti-loosening installation component includes an anti-loosening installation groove opened inside the sealing bolt body. A threaded installation column is threadedly connected inside the anti-loosening installation groove. One end of the threaded installation column is slidably fitted with a sliding circular plate. A tension spring is connected between the sliding circular plate and the sealing bolt body. A sliding plate is circumferentially connected to one side of the sliding circular plate. The outer periphery of the sliding plate is slidably fitted with a sliding groove. An anti-loosening reinforcement plate is connected to one side of the sliding plate. The outer periphery of the anti-loosening reinforcement plate is slidably fitted with a reinforcement sliding groove.

[0008] Furthermore, the sliding groove and the reinforcement sliding groove are respectively opened inside the sealing bolt body.

[0009] Furthermore, a cross groove is opened at one end of the threaded installation column.

[0010] Furthermore, in order to improve the sealing installation effect, the sealing installation assembly includes a mounting sleeve, the mounting sleeve is sleeved on the periphery of the sealing bolt body, and a rubber sealing ring is matched on the periphery of the mounting sleeve.

[0011] The beneficial effects of the utility model are:

[0012] The utility model makes improvements on the prior art. In actual use, the sealing bolt body is reinforced again through the anti-loosening installation component after the sealing bolt is installed, thereby solving the problem that the prior art adding self-locking nuts and thread glue can achieve a certain anti-loosening effect, but the anti-loosening effect is weak, and it is more laborious to disassemble the bolt in the later stage. It also avoids the situation that the non-removable bolts can only be cut off by a cutting machine in order to ensure the integrity of the bolt installation surface during subsequent disassembly. If brute force is used to remove the non-removable bolts, the installation surface will be scratched, causing many inconveniences to the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] According to an embodiment of the present invention, a loosening-proof sealing bolt with good tightness is provided, including a sealing bolt body 1. An anti-loosening installation component 2 is arranged inside the sealing bolt body 1, and a sealing installation component 3 is arranged on one side of the anti-loosening installation component 2.

[0022] As Figures 1 - 4 shown, for the loosening-proof sealing bolt with good tightness according to the embodiment of the present invention, the anti-loosening installation component 2 includes an anti-loosening installation groove 201 opened inside the sealing bolt body 1. A threaded installation post 202 is threadedly connected inside the anti-loosening installation groove 201. One end of the threaded installation post 202 is slidably fitted with a sliding circular plate 203. A tensile spring 204 is connected between the sliding circular plate 203 and the sealing bolt body 1. A sliding plate 205 is circumferentially connected to one side of the sliding circular plate 203. The outer periphery of the sliding plate 205 is slidably fitted with a sliding groove 206. One side of the sliding plate 205 is connected with an anti-loosening reinforcement plate 207. The outer periphery of the anti-loosening reinforcement plate 207 is slidably fitted with a reinforcement sliding groove 208. The sliding groove 206 and the reinforcement sliding groove 208 are respectively opened inside the sealing bolt body 1. A cross slot 4 is opened at one end of the threaded installation post 202.

[0023] Through the above technical solution, after the sealing bolt body 1 is installed, a cross screwdriver is used to drive the sealing bolt body 1 to rotate through the cross slot 4. The anti-loosening installation slot 201 is threadedly connected to the sealing bolt body 1. When the sealing bolt body 1 rotates, it can rotate and move in the anti-loosening installation slot 201. Then, when the sealing bolt body 1 rotates and moves, it can drive the sliding circular plate 203 to move. When the sliding circular plate 203 moves, it can drive the sliding plate 205 to move in the sliding slot 206 and the reinforcement sliding slot 208. When the sliding plate 205 moves, it can drive the anti-loosening reinforcement plate 207 to move in the reinforcement sliding slot 208. Then, the anti-loosening reinforcement plate 207 can be pushed out, so as to achieve the effect of preventing the sealing bolt from loosening and being tight.

[0024] As Figures 1 - 4 shown, for the anti-loosening sealing bolt with good tightness according to the embodiment of the present invention, the sealing installation assembly 3 includes an installation sleeve 301. The installation sleeve 301 is sleeved on the periphery of the sealing bolt body 1, and a rubber sealing ring 302 is fitted on the periphery of the installation sleeve 301.

[0025] Through the above technical solution, by setting the installation sleeve 301, the effect of facilitating the installation of the rubber sealing ring 302 is achieved, and the rubber sealing ring 302 can improve the sealing effect of the sealing bolt body 1.

[0026] As Figure 4 shown, the installation sleeve 301 is sleeved on the sealing bolt body 1. The rubber sealing ring 302 is sleeved between the upper and lower flange plates of the installation sleeve 301. When assembling, the sleeve protrusion 5 is processed after the installation sleeve 301 is sleeved on the sealing bolt body 1. The protrusion 5 will be stuck on the sealing bolt body 1, so that the installation sleeve 301 will not slide out of the sealing bolt body 1. The sealing bolt body 1 is used to connect the plastic part 12 and the metal part 11. The depth of the light hole on the metal part 11 has been calculated in advance. When the pressure applied by the sealing bolt body 1 to the rubber sealing ring 302 reaches the requirement, the lower flange plate of the installation sleeve 301 just reaches the bottom of the light hole of the metal part 11. When the sealing bolt body 1 is further tightened, the pressure applied by the sealing bolt body 1 is transmitted to the lower metal part 11 through the sleeve, and will not further compress the rubber sealing ring 302, and will not apply a greater force to the metal part 11 either. Thus, three purposes are achieved: protecting the upper metal part 11 from being damaged, the rubber sealing ring 302 also reaches the required pressing force, and the tightening force of the sealing bolt body 1 also reaches the required value.

[0027] To facilitate the understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0028] In summary, by means of the above technical solution of the present utility model, after the sealing bolt body 1 is installed, a cross screwdriver is used to drive the sealing bolt body 1 to rotate through the cross slot 4. The anti-loosening installation slot 201 is threadedly connected to the sealing bolt body 1. When the sealing bolt body 1 rotates, it can rotate and move in the anti-loosening installation slot 201. Then, when the sealing bolt body 1 rotates and moves, it can drive the sliding circular plate 203 to move. When the sliding circular plate 203 moves, it can drive the sliding plate 205 to move in the sliding slot 206 and the reinforcement sliding slot 208. When the sliding plate 205 moves, it can drive the anti-loosening reinforcement plate 207 to move in the reinforcement sliding slot 208. Then, the anti-loosening reinforcement plate 207 can be pushed out, so as to achieve the effect of preventing the sealing bolt from loosening and being tightened.

[0029] By providing the installation sleeve 301, the effect of facilitating the installation of the rubber sealing ring 302 is achieved, and the rubber sealing ring 302 can improve the sealing effect of the sealing bolt body 1.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
