Description
Technical Field
[0001] This utility model relates to the field of snap-fit connectors, and more particularly to a snap-fit self-locking connector. Background Technology
[0002] A snap-lock connector is a device that achieves quick connection and secure locking through a mechanical structure. Its core lies in the shape matching of the elastic snap and the socket slot. When inserted, the snap deforms to complete the automatic positioning. After being in place, it returns to its original shape and embeds into the slot to form a mechanical lock. It is widely used in electronic equipment, industrial machinery, automotive parts, and communication and medical fields.
[0003] Because the connecting wire is easily pulled during use, the limiting teeth will rub against the limiting groove under the action of tension, causing wear on the limiting teeth. Since the limiting teeth are fixed to the overall structure, tools are needed to replace the limiting teeth, or the limiting teeth and the overall structure can be replaced together, which is time-consuming, laborious and easy to waste materials. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a snap-locking connector.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a snap-lock connector, comprising a fixing block and a connecting block, wherein fixing tubes are fixedly connected to both ends of the fixing block near the snap-lock body, the snap-lock body is fixedly connected to one end of the fixing block near the connecting block, a connecting wire is fixedly connected to one end of the connecting block away from the fixing block, a fixing structure is provided on one side of the connecting block near the fixing tubes, a slot is fixedly connected to one end of the connecting block near the snap-lock body, and the slot engages with the snap-lock body, a disassembly structure is provided on both sides of the fixing structure, a dustproof structure is provided on both sides of the fixing tubes, and sliding grooves are provided on both sides of the connecting grooves at both ends of the connecting block.
[0006] Furthermore, transverse grooves are provided on both sides of the inner wall of the fixed tube, and fixed grooves are provided at equal intervals at both ends of the inner wall of the fixed tube.
[0007] Furthermore, the disassembly structure includes a slider, which is slidably connected in the connecting grooves on both sides of the connecting block, and both ends of the slider are provided with placement grooves arranged at equal intervals.
[0008] Furthermore, a second spring is fixedly connected inside the placement groove, and a limit block is fixedly connected to one end of the second spring near the slide groove, and the limit block is slidably connected to the slide groove.
[0009] Furthermore, the fixing structure includes a connecting rod, which is rotatably connected to the middle of the slider and slidably connected to the fixing tube. A holding block is fixedly connected to the end of the connecting rod away from the fixing tube. Fixing teeth are fixedly connected to the outer wall of the connecting rod at equal intervals, and the fixing teeth are slidably connected to the transverse groove and engaged with the fixing groove.
[0010] Furthermore, the dustproof structure includes fixed rods, which are equidistantly arranged and rotatably connected to the inside of the fixed tube near the connecting rod. A connecting shaft is fixedly connected to the side of the fixed rods on both sides that are close to each other.
[0011] Furthermore, a dustproof block is fixedly connected to one end of the connecting shaft that is close to the other end, and a first spring is fixedly connected to the other end of the connecting shaft that is away from the dustproof block, and the first spring is fixedly connected to the fixing tube.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, by setting a sliding groove and a disassembly structure, when the fixed tooth needs to be replaced, the holding block is grasped and pulled. Under the pull of the holding block, the connecting rod drives the slider to slide in the connecting groove on the connecting block. The second spring fixed in the placement groove drives the limiting block to slide in the sliding groove as the slider slides, so that the connecting rod and the fixed tooth can be removed from the connecting block, and the connection and fixation of the connecting rod and the fixed tooth can be released. This makes it easier to replace the connecting rod and the fixed tooth separately, which is more time-saving, labor-saving and cost-saving.
[0014] 2. In this utility model, by setting a dustproof structure, when the fixing teeth on the connecting rod move in the transverse groove, the dustproof blocks on both sides of the fixed tube are squeezed as the connecting rod and fixing teeth move. With the connecting shaft as the axis, the connecting shaft and the fixing rod are driven to rotate on the fixed tube. The first spring fixed at one end of the connecting shaft deforms under the rotation of the connecting shaft, so that the dustproof block is in contact with the inner wall of the fixed tube. When the fixing teeth have finished moving, they lose the squeezing of the dustproof block. The first spring rebounds as the dustproof block loses the squeezing, driving the connecting shaft and the fixing rod to rotate on the fixed tube. The dustproof block moves to the initial position as it rotates, blocking the gap between the fixed tube and the connecting rod, preventing dust from entering the fixed tube and causing unstable connection between the fixed tube and the connecting rod, thus improving the stability of the connection.

Detailed Implementation
[0022] Please see Figure 1-5 This utility model provides a technical solution: a snap-lock connector, including a fixing block 1 and a connecting block 2. The fixing block 1 has a fixing tube 11 fixedly connected to both ends of the side near the snap-lock body 12. The fixing block 1 has a snap-lock body 12 fixedly connected to one end of the fixing block 1 near the connecting block 2. The connecting block 2 has a connecting wire 21 fixedly connected to one end away from the fixing block 1. The side of the connecting block 2 near the fixing tube 11 is provided with a fixing structure. The end of the connecting block 2 near the snap-lock body 12 is fixedly connected with a slot 23, and the slot 23 engages with the snap-lock body 12. The fixing structure has a disassembly structure on both sides. The fixing tube 11 has a dustproof structure on both sides. The connecting slots at both ends of the connecting block 2 have sliding grooves 3.
[0023] Please see Figure 3 and Figure 4 The inner wall of the fixed tube 11 has horizontal grooves 111 on both sides, and fixed grooves 112 are equidistantly arranged at both ends of the inner wall of the fixed tube 11. The dustproof structure includes fixed rods 42, which are equidistantly arranged and rotatably connected to the inside of the fixed tube 11 near the connecting rod 222. The two fixed rods 42 are fixedly connected to the side of each other, and a dustproof block 4 is fixedly connected to the end of the connecting shaft 41 that is close to each other. A first spring 43 is fixedly connected to the end of the connecting shaft 41 that is away from the dustproof block 4, and the first spring 43 is fixedly connected to the fixed tube 11.
[0024] In this embodiment, when the fixing teeth 223 on the connecting rod 222 move within the transverse groove 111, the dustproof blocks 4 on both sides of the fixed tube 11 are squeezed as the connecting rod 222 and the fixing teeth 223 move. With the connecting shaft 41 as the axis, the connecting shaft 41 and the fixing rod 42 rotate on the fixed tube 11. The first spring 43 fixed at one end of the connecting shaft 41 deforms under the rotation of the connecting shaft 41, so that the dustproof block 4 fits against the inner wall of the fixed tube 11. When the fixing teeth 223 finish moving, they lose the squeezing of the dustproof block 4. The first spring 43 rebounds as the dustproof block 4 loses the squeezing, driving the connecting shaft 41 and the fixing rod 42 to rotate on the fixed tube 11. The dustproof block 4 moves to the initial position as it rotates, blocking the gap between the fixed tube 11 and the connecting rod 222, preventing dust from entering the fixed tube 11 and causing instability in the connection between the fixed tube 11 and the connecting rod 222, thus improving the stability of the connection.
[0025] Please see Figure 1 , Figure 2 as well as Figure 5 The disassembly structure includes a slider 5, which is slidably connected in the connecting grooves on both sides of the connecting block 2. Both ends of the slider 5 are provided with placement grooves 51 arranged at equal intervals. A second spring 52 is fixedly connected inside the placement groove 51. A limit block 53 is fixedly connected to one end of the second spring 52 near the slide groove 3, and the limit block 53 is slidably connected to the slide groove 3.
[0026] In this embodiment, when the fixing tooth 223 needs to be replaced, the gripping block 221 is held and pulled. Under the pull of the gripping block 221, the connecting rod 222 drives the slider 5 to slide in the connecting groove on the connecting block 2. The second spring 52 fixed in the placement groove 51 drives the limiting block 53 to slide in the sliding groove 3 as the slider 5 slides, so that the fixing tooth 223 can be removed from the connecting block 2, and the connection and fixation of the fixing tooth 223 can be released. This makes it easier to replace the fixing tooth 223 individually, which is more time-saving, labor-saving and cost-saving.
[0027] Please see Figure 1 , Figure 2 as well as Figure 5 The fixed structure includes a connecting rod 222, which is rotatably connected to the middle of the slider 5 and slidably connected to the fixed tube 11. A holding block 221 is fixedly connected to the end of the connecting rod 222 away from the fixed tube 11. Fixed teeth 223 are equidistantly arranged and fixedly connected to the outer wall of the connecting rod 222, and the fixed teeth 223 are slidably connected to the transverse groove 111 and engaged with the fixed groove 112.
[0028] In this embodiment, when the gripping block 221 is rotated, the connecting rod 222 rotates 90 degrees with the rotation of the gripping block 221, causing the slot 23 to fit into the transverse groove 111 inside the fixing tube 11. When the fixing tooth 223 moves to the designated position, the gripping block 221 is rotated 90 degrees again, so that the fixing tooth 223 is engaged in the fixing groove 112, limiting and fixing the fixing tooth 223, and ensuring the stability of the connection between the slot 23 and the buckle body 12.
[0029] Working principle: First, the slot 23 is engaged with the buckle body 12. Holding the gripping block 221 and rotating it causes the connecting rod 222 to rotate 90 degrees, engaging the slot 23 with the horizontal groove 111 inside the fixing tube 11. When the fixing tooth 223 moves to the designated position, holding the gripping block 221 is rotated 90 degrees again, causing the fixing tooth 223 to engage in the fixing groove 112, limiting and fixing the fixing tooth 223, ensuring the stability of the connection between the slot 23 and the buckle body 12. The dustproof blocks 4 on both sides of the fixing tube 11 are squeezed by the movement of the connecting rod 222 and the fixing tooth 223, with the connecting shaft 41 as the axis, driving the connecting rod 222 to rotate 90 degrees. The connecting shaft 41 and the fixing rod 42 rotate on the fixing tube 11. The first spring 43, which is fixed to one end of the connecting shaft 41, deforms under the rotation of the connecting shaft 41, so that the dust block 4 fits against the inner wall of the fixing tube 11. When the fixing tooth 223 moves and loses its pressure on the dust block 4, the first spring 43 rebounds as the dust block 4 loses its pressure, driving the connecting shaft 41 and the fixing rod 42 to rotate on the fixing tube 11. The dust block 4 moves to the initial position as it rotates, blocking the gap between the fixing tube 11 and the connecting rod 222, preventing dust from entering the fixing tube 11 and causing unstable connection between the fixing tube 11 and the connecting rod 222.
[0030] Next, when it is necessary to replace the fixed tooth 223, hold the grip block 221 and pull it. The connecting rod 222 will drive the slider 5 to slide in the connecting groove on the connecting block 2 under the pull of the grip block 221. The second spring 52 fixed in the placement groove 51 will drive the limiting block 53 to slide in the sliding groove 3 as the slider 5 slides, so that the fixed tooth 223 can be removed from the connecting block 2, and the connection and fixation of the fixed tooth 223 can be released, making it convenient to replace the fixed tooth 223 individually.
