A rivet with a locking device

Abstract

This utility model discloses a rivet with a locking device, relating to the field of rivets. It includes a rivet disc, a rivet sleeve fixedly connected to the bottom of the rivet disc, and a rivet rod slidably connected inside the rivet disc. A rivet head is fixedly connected to the bottom end of the rivet rod, and a placement groove is formed inside the rivet rod. A locking component is disposed inside the placement groove. By setting up the locking component, when the rivet sleeve deforms and flattens, the locking block moves to the slot. At this time, the spring, which is in a compressed state, deforms, thereby driving the locking block to move to the slot, locking the rivet rod and the rivet disc, improving the stability of the rivet connection. Furthermore, when it is necessary to disassemble the rivet, the locking block can be restored to its original shape from the slot using a tool, so that the rivet rod and the rivet disc are no longer locked. At this point, only the deformed rivet sleeve needs to be destroyed to disassemble the rivet, bringing convenience to rivet disassembly.

Description

Technical Field

[0001] This utility model relates to the field of rivets, and in particular to a rivet with a locking device. Background Technology

[0002] Rivets include open-type blind rivets, closed-type rivets, and ring groove rivets. Due to their simplicity and practicality, rivets are usually used to fix some plates or small parts. When using blind rivets, the riveting machine first removes the rivet from the rivet, and at the same time, the rivet head end will squeeze the rivet shell to form a flat plate with a diameter larger than the hole diameter, thus realizing the riveting of one end to the other.

[0003] The patent, entitled "Anti-Pull Rivet Head Loosening Rivet" (patent application number: CN220890705U), comprises a rivet shank with a rivet head mounted on its top. A rivet sleeve is movably fitted onto the outer side of the rivet shank. A cam is mounted on the end of the rivet sleeve away from the rivet head. A locking mechanism, including a locking block, is provided inside the rivet shank to lock the rivet shank in place. An adapter mechanism, including a slot formed on the inner wall of the cam, is provided inside the cam to fix the locking block. The engagement of the locking block and the slot securely locks the rivet shank and rivet head onto the cam after installation, increasing the rivet's strength. Simultaneously, the rivet's structure is relatively simple, preventing a significant reduction in its inherent strength.

[0004] In the above case, during use, after the locking block is inserted into the slot, the rivet rod and the cam form an integral structure, increasing the difficulty of subsequent rivet disassembly. Furthermore, when assembling the rivet rod and the cam, workers are prone to inserting the rivet rod backwards, causing the locking block of the rivet rod to enter the slot under the action of the spring, making it impossible to pull the rivet rod out again for reassembly. This increases the scrap rate of the product and brings inconvenience to the use of the rivet.

[0005] Therefore, it is necessary to propose a rivet with a locking device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a rivet with a locking device to solve the problems mentioned in the background art, which are that when the locking block is inserted into the slot, the rivet rod and the cam form an integral structure, increasing the difficulty of subsequent disassembly of the rivet. Furthermore, when assembling the rivet rod and the cam, workers may easily insert the rivet rod backwards, causing the locking block of the rivet rod to be pushed into the slot by the spring, making it impossible to pull the rivet rod out again for reassembly, increasing the scrap rate of the product and causing inconvenience in the use of the rivet.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rivet with a locking device, comprising a rivet disc, characterized in that: a rivet sleeve is fixedly connected to the bottom of the rivet disc, and a rivet rod is slidably connected inside the rivet disc, a rivet head is fixedly connected to the bottom end of the rivet rod, and the rivet rod slides along the inside of the rivet sleeve;

[0008] The rivet rod has a placement groove inside, the rivet disc has a locking groove inside, the placement groove is provided with a locking component, and the locking groove is connected to the placement groove;

[0009] The locking assembly includes a fixing block, a limiting rod, a locking block, and a spring. The fixing block is fixedly connected to the limiting rod, the outer end of the limiting rod is movably connected to the locking block, and the spring is sleeved on the limiting rod to abut against the locking block.

[0010] Preferably, the outside of the fixing block is fixedly connected to the inside of the placement groove, and the outside of the card block is slidably connected to the inside of the placement groove.

[0011] Preferably, the inside of the spring is slidably connected to the outside of the limiting rod.

[0012] Preferably, the slot extends through and to the outside of the rivet disc.

[0013] Preferably, the card slot and the card block are compatible.

[0014] Preferably, both the card block and the fixing block have arc surfaces on their sides.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting a locking component, when using the rivet, first insert one end of the rivet head into the mounting hole, then install the rivet shank on the rivet gun. Use the rivet gun to pull the rivet head, causing the rivet sleeve to deform, thereby fixing the object. When the rivet sleeve deforms and flattens, the locking block moves to the slot. At this time, the spring, which is under compression, will deform, thereby driving the locking block to move to the slot, locking the rivet shank and the rivet disc, improving the stability of the rivet connection. When it is necessary to disassemble the rivet, the locking block can be restored to its original shape from the slot with a tool, so that the rivet shank and the rivet disc are no longer locked. At this time, only the deformed rivet sleeve needs to be destroyed to disassemble the rivet, which brings convenience to the disassembly of the rivet.

[0017] 2. When assembling rivets, if a worker mistakenly inserts the rivet shank backwards, causing the locking block to enter the slot under the spring force, the worker can use a long rod to reset the locking block back into the slot. This facilitates the separation of the rivet shank from the rivet disc, avoiding the problem of rivet failure due to incorrect assembly and thus improving the practicality of the rivets.

[0024] 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.

[0025] This utility model provides, for example Figure 1 - Figure 4The rivet with locking device shown includes a rivet disc 1, a rivet sleeve 4 fixedly connected to the bottom of the rivet disc 1, and a rivet rod 2 slidably connected inside the rivet disc 1. A rivet head 3 is fixedly connected to the bottom end of the rivet rod 2. The outside of the rivet rod 2 is slidably connected to the inside of the rivet sleeve 4. A placement groove 5 is provided inside the rivet rod 2, and a locking assembly is provided inside the placement groove 5. The locking assembly includes a fixing block 6, a limiting rod 7, a locking block 8, and a spring 10. The side of the fixing block 6 is fixedly connected to one end of the limiting rod 7. Next, the outside of the limiting rod 7 is slidably connected to the inside of the locking block 8. A spring 10 is fixedly connected to the side of the fixing block 6. One end of the spring 10 is fixedly connected to the side of the locking block 8. The outside of the fixing block 6 is fixedly connected to the inside of the placement groove 5. The outside of the locking block 8 is slidably connected to the inside of the placement groove 5. The inside of the spring 10 is slidably connected to the outside of the limiting rod 7. A slot 11 is opened inside the rivet disc 1. The slot 11 passes through and extends to the outside of the rivet disc 1. The slot 11 is compatible with the locking block 8. When using the rivet, first insert one end of the rivet head 3 into the mounting hole, then install the rivet shank 2 on the rivet gun. Use the rivet gun to pull the rivet head 3, causing the rivet sleeve 4 to deform, thus fixing the object. When the rivet sleeve 4 deforms and flattens, the locking block 8 moves to the slot 11. At this time, the compressed spring 10 deforms, causing the locking block 8 to move to the slot 11, locking the rivet shank 2 and the rivet disc 1, improving the stability of the rivet connection. When it is necessary to disassemble the rivet, a tool can be used to restore the locking block 8 to its original shape from the slot 11, so that the rivet shank 2 and the rivet disc 1 are no longer locked. Then, only the deformed rivet sleeve 4 needs to be destroyed to disassemble the rivet, making rivet disassembly convenient. Furthermore, because the inside of the locking block 8 is slidably connected to the outside of the limiting rod 7, the stability of the locking block 8's movement is improved.

[0026] In addition, both the locking block 8 and the fixing block 6 have arc surfaces 9 on their sides. When assembling the rivets, if the worker accidentally inserts the rivet rod 2 backwards, causing the locking block 8 to enter the slot 11 under the force of the spring 10, the worker can use a long rod to reset the locking block 8 from the slot 11 back into the placement slot 5, making it easier to separate the rivet rod 2 from the rivet disc 1. This avoids the problem of scrapping the rivets due to incorrect assembly, thereby improving the practicality of the rivets. The arc surfaces 9 on the sides of both the locking block 8 and the fixing block 6 facilitate the sliding of the rivet rod 2 inside the rivet sleeve 4.

[0027] Working principle: When using the rivet, first insert one end of the rivet head 3 into the mounting hole, then install the rivet shank 2 on the rivet gun. The rivet gun pulls the rivet head 3, causing the rivet sleeve 4 to deform, thus fixing the object. When the rivet sleeve 4 deforms and flattens, the locking block 8 moves to the slot 11. At this time, the compressed spring 10 deforms, causing the locking block 8 to move to the slot 11, locking the rivet shank 2 and the rivet disc 1, improving the stability of the rivet connection. Furthermore, when it is necessary to disassemble the rivet, the locking block 8 can be restored to its original shape from the slot 11 using tools. This design removes the locking mechanism between the rivet rod 2 and the rivet disc 1. The rivet can then be disassembled simply by breaking the deformed rivet sleeve 4, facilitating rivet removal. If a worker mistakenly inserts the rivet rod 2 backwards, causing the locking block 8 to enter the slot 11 under the force of the spring 10, the worker can use a long rod to return the locking block 8 to its original position in the placement slot 5 from the slot 11. This facilitates the separation of the rivet rod 2 from the rivet disc 1, preventing the rivet from being scrapped due to incorrect assembly and thus improving its practicality. Both the locking block 8 and the fixing block 6 have arc surfaces 9 on their sides, which facilitate the sliding of the rivet rod 2 inside the rivet sleeve 4.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the principles of the present utility model should be included within the protection scope of the present utility model.
