Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a novel anti-loosening bolt. Background Technique

[0002] A bolt is a fastener. In some cases, bolts are needed to connect and fix two components together. However, due to vibration, simply using bolts will cause the bolts to loosen, resulting in the inability to firmly connect the two components together. Currently, generally, an adhesive is first injected into the threaded hole of the component, and then the bolt is screwed in. Therefore, it is necessary to carry the adhesive during connection, which is not very convenient. Thus, we propose a novel anti-loosening bolt to solve the above problems. Content of the Utility Model

[0003] (I) Technical Problems to be Solved

[0004] Aiming at the deficiencies of the prior art, the utility model provides a novel anti-loosening bolt, which solves the problems raised in the above background technique.

[0005] (II) Technical Solutions

[0006] The utility model specifically adopts the following technical solutions to achieve the above purposes:

[0007] A novel anti-loosening bolt, including a bolt head and a rod body. The bolt head is fixed at the top of the rod body. The surface of the rod body is provided with threads. A cylindrical cavity is opened inside the rod body. A fixing block is fixed inside the cylindrical cavity. A packaging film is arranged inside the cylindrical cavity. The packaging film is filled with adhesive glue. The packaging film is arranged below the fixing block. Through holes are opened on the surface of the rod body, and the through holes are all communicated with the cylindrical cavity. A piercing component for piercing the packaging film is arranged on the bolt head.

[0008] Further, the piercing component includes a spring. A groove is opened at the top of the bolt head. The spring is fixed inside the groove. The top end of the spring is fixed with a pressing block. The pressing block is slidably installed inside the groove. A piercing rod is fixed at the bottom of the pressing block. The piercing rod is arranged inside the spring. The piercing rod slidably penetrates through the bottom of the bolt head and extends into the cylindrical cavity.

[0009] Further, an avoidance hole for avoiding the piercing rod is opened in the middle of the fixing block.

[0010] Further, a through hole for the piercing rod to pass through is opened at the bottom of the bolt head.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, the utility model provides a novel anti-loosening bolt, which has the following beneficial effects:

[0013] In the utility model, by arranging a cylindrical cavity in the rod body and setting structures such as a fixing block, a packaging film, an adhesive glue, a through hole and a puncturing component, it is not necessary for the user to inject an adhesive into the threaded hole of the component first. The user can directly screw it in, and then puncture the packaging film through the puncturing component. The adhesive glue will flow out from the through hole of the rod body, so that the bonding and fixing effect can be achieved. It is not necessary for the user to carry the adhesive, so it is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment

[0020] As Figure 1 , Figure 2 and Figure 3As shown in the figure, a new type of anti-loosening bolt proposed by an embodiment of the present utility model includes a bolt head 1 and a rod body 2. The bolt head 1 is fixed at the top of the rod body 2. The surface of the rod body 2 is provided with threads. A cylindrical cavity 3 is opened inside the rod body 2. A fixing block 4 is fixed inside the cylindrical cavity 3. A packaging film 5 is arranged inside the cylindrical cavity 3. An adhesive glue 6 is filled inside the packaging film 5. The packaging film 5 is arranged below the fixing block 4. Through holes 7 are opened on the surface of the rod body 2. The through holes 7 are all communicated with the cylindrical cavity 3. A puncturing component 8 for puncturing the packaging film 5 is arranged on the bolt head 1. The puncturing component 8 includes a spring 801. A groove 9 is opened at the top of the bolt head 1. The spring 801 is fixed inside the groove 9. The top end of the spring 801 is fixed with a pressing block 802. The pressing block 802 is slidably installed inside the groove 9. The bottom of the pressing block 802 is fixed with a puncturing rod 803. The puncturing rod 803 is arranged inside the spring 801. The puncturing rod 803 slidably penetrates through the bottom of the bolt head 1 and extends into the cylindrical cavity 3.

[0021] When it is necessary to connect two components together, first align the two components, then screw in the rod body 2, and then puncture the packaging film 5 through the puncturing component 8. The specific operation process is as follows: press down the pressing block 802. At this time, the spring 801 will be compressed. The pressing block 802 can drive the puncturing rod 803 to move downward. The puncturing rod 803 can puncture the packaging film 5. The adhesive glue 6 inside the packaging film 5 will flow out from the through holes 7 of the rod body 2, so that the connection between the rod body 2 and the component can be made more firm. It is not necessary for the user to carry an adhesive, so it is more convenient.

[0022] As Figure 3 shown, in some embodiments, an avoidance hole 10 for avoiding the puncturing rod 803 is opened in the middle of the fixing block 4. A through hole 11 for the puncturing rod 803 to pass through is opened at the bottom of the bolt head 1, so that the puncturing rod 803 can smoothly pass through the bottom of the bolt head 1 and the fixing block 4, and thus can smoothly puncture the packaging film 5.

[0023] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
