Abstract
Description
Technical Field
[0001] This utility model relates to the field of T-nut technology, and in particular to a T-nut that is easy to connect. Background Technology
[0002] T-nuts are fasteners specifically designed for T-slots. T-nuts use their T-shaped structure to work with T-slots and are mainly used to fix parts in the T-slots of mechanical structures. They are easy to install and provide positioning and locking.
[0003] The existing T-nut technology has the following drawbacks in practical use:
[0004] In the use of existing T-nuts, when the bolt connected to the T-nut enters the T-thread, the bolt may be tilted. When the bolt enters the T-thread at an angle, it may get stuck after rotating the bolt a few turns to engage the T-nut threads, preventing the bolt threads from moving further down. This means that the bolt must be inserted vertically into the T-nut before the external threads are engaged, making the connection very inconvenient. Utility Model Content
[0005] In the existing technology, when using a T-nut, the bolt may tilt when it enters the T-thread. After rotating the bolt a few turns into the T-thread, it may jam, preventing further threading. This results in the bolt needing to be inserted vertically into the T-nut before the external threads are fully inserted, making the connection very inconvenient. This invention provides a T-nut that facilitates easy connection.
[0006] The technical solution adopted by this utility model is as follows: a T-shaped nut that is easy to connect, including a T-shaped nut body, a threaded groove on the inner wall of the T-shaped nut body, and an anti-deviation component inside the T-shaped nut body. The anti-deviation component includes a guide block, a sector block, and a limiting groove. A rotating block is fixedly provided at the top of the sector block, and a rotating rod is provided at the bottom of the guide block. The rotating rod is rotatably connected to the rotating block. A torsion spring connected to the guide block is provided on the outer wall of the rotating block. A limiting block is fixedly provided on the outer wall of one side of the sector block, and a limiting block is fixedly provided on the outer wall of one side of the guide block. The limiting groove is opened on the inner wall of the T-shaped nut body, and both limiting blocks are slidably connected inside the limiting groove. A spring connected to limiting block one is provided on the inner wall at the bottom of the limiting groove.
[0007] Furthermore, the T-nut body is provided with a self-locking assembly inside, and the self-locking assembly includes a movable cavity, a push rod, a support rod, a moving block, and a guide rod, with the movable cavity being opened inside the T-nut body.
[0008] Furthermore, the support rod is fixedly mounted on the inner wall of the movable cavity, and the push rod is rotatably sleeved on the outside of the support rod.
[0009] Furthermore, the top of the push rod is provided with a ball, and the bottom of the push rod extends to the outside of the movable cavity.
[0010] Furthermore, the guide rod is fixedly mounted on the inner wall of the movable cavity, and the moving block is slidably sleeved on the outside of the guide rod.
[0011] Furthermore, a second spring is provided on the outer wall of the movable block, and the other end of the second spring away from the movable block is fixed to the inner wall of the movable cavity.
[0012] Furthermore, an insert block is provided on the outer wall of one side of the movable block, and the spring is sleeved on the outside of the insert block.
[0013] The beneficial effects of this utility model are:
[0014] 1. This utility model, through the anti-deviation component, can guide the nut connected to the T-nut body, allowing the bolt connected to the T-nut body to enter the T-nut in a perpendicular state and engage with the T-nut thread. This avoids the situation where the bolt connected to the T-nut body enters the T-nut in a tilted state and gets stuck in the T-nut thread, making it more convenient to connect the T-nut body to the external bolt thread.
[0015] 2. Secondly, this utility model uses a self-locking component. When the lower thread of the outer nut descends to the lowest end of the T-nut, it will push the bottom end of the push rod, causing the top end of the push rod to push the moving block and the insert block, so that the insert block is inserted into the outer thread. This can lock the outer nut and prevent the T-nut body from coming loose after being vibrated for a long time when it is used on vibrating equipment. Attached Figure Description

[0024] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described below.
[0025] To address the problems existing in the background art, this application proposes the following technical solution: a T-nut that facilitates connection.
[0026] The specific technical solution includes a T-shaped nut body 1, with a threaded groove 2 on the inner wall of the T-shaped nut body 1. An anti-deviation component 3 is installed inside the T-shaped nut body 1. The anti-deviation component 3 includes a guide block 301, a sector block 302, and a limiting groove 307. A rotating block 303 is fixedly installed on the top of the sector block 302. A rotating rod 304 is installed at the bottom of the guide block 301, and the rotating rod 304 is rotatably connected to the rotating block 303. A torsion spring 305 connected to the guide block 301 is installed on the outer wall of the rotating block 303. The outer side of the sector block 302... A limiting block 306 is fixedly installed on the wall, and a limiting block 309 is fixedly installed on the outer wall of one side of the guide block 301. A limiting groove 307 is opened on the inner wall of the T-nut body 1, and both the limiting block 306 and the limiting block 309 are slidably connected inside the limiting groove 307. A spring 308 connected to the limiting block 306 is provided on the inner wall at the bottom of the limiting groove 307. The anti-deviation component 3 can guide the external bolt threaded to the T-nut body 1, and can make the external bolt descend vertically into the T-nut body 1.
[0027] In specific implementations, such as Figure 1 and Figure 5 As shown, the T-nut body 1 is provided with a self-locking component 4 inside, and the self-locking component 4 includes a movable cavity 401, a push rod 402, a support rod 403, a moving block 404 and a guide rod 406. The movable cavity 401 is opened inside the T-nut body 1, and the self-locking component 4 is used to lock the T-nut body 1 with the external bolt.
[0028] Furthermore, the support rod 403 is fixedly installed on the inner wall of the movable cavity 401, and the push rod 402 is rotatably sleeved on the outside of the support rod 403, so that the support rod 403 can support the push rod 402.
[0029] Furthermore, a ball 408 is provided at the top of the push rod 402, and the bottom end of the push rod 402 extends to the outside of the movable cavity 401. When the push rod 402 rotates, it will drive the ball 408 to rotate.
[0030] Furthermore, the guide rod 406 is fixedly mounted on the inner wall of the movable cavity 401, and the moving block 404 is slidably sleeved on the outside of the guide rod 406. The guide rod 406 can guide and support the moving block 404.
[0031] Furthermore, a second spring 407 is provided on the outer wall of the movable block 404, and the other end of the second spring 407 away from the movable block 404 is fixed on the inner wall of the movable cavity 401. The elastic force of the second spring 407 can push the movable block 404 to move back.
[0032] Furthermore, an insert block 405 is provided on the outer wall of one side of the movable block 404, and a spring 407 is sleeved on the outside of the insert block 405. When the movable block 404 moves, it will drive the insert block 405 to move.
[0033] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:
[0034] In use, the external bolt connected to the T-nut body 1 is moved downwards. The external bolt will push against the sector block 302 as it moves downwards. The sector block 302 will slide downwards within the limiting groove 307. The guide block 301 is initially tilted due to the torsional force of the torsion spring. When the guide block 301 is blocked by the top of the T-nut body 1, it will rotate, making the guide block 301 vertical. As the sector block 302 moves downwards, the guide block 301 will be vertically drawn into the interior of the T-nut body 1. The second limiting block 309 will slide within the limiting groove 307. The two guide blocks 301 will surround the external bolt, ensuring that the external bolt is vertical and can enter the T-nut body 1 vertically, preventing the external bolt from entering the T-nut body 1 in a non-vertical state. After the nut body 1 and the T-nut body 1 are threaded together for a few turns, the nut gets stuck. Then the external bolt is threaded, and the external bolt continues to push the sector block 302 downward. The sector block 302 drives the guide block 301 downward. The guide block 301 can always guide the external bolt. When the external bolt is threaded to the bottom of the T-nut body 1, the external bolt will push the push rod 402. The push rod 402 will drive the ball 408 to rotate and push the moving block 404. The moving block 404 will drive the insert block 405 to move, so that the insert block 405 is inserted into the external bolt. This can lock the external bolt and the T-nut body 1, and prevent the T-nut body 1 and the external bolt from coming loose due to vibration after long-term use on vibrating equipment.
