Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a press-fit inward snap fastener structure. Background Technology

[0002] Locking is a common technical means in existing technology, which locks the structure of equipment.

[0003] Application No. 2019107233927 discloses a reverse sliding press-lock mechanism, a battery converter, a battery, and an electric vehicle. The mechanism consists of a lifting mechanism composed of a drive rack, a driven rack, and a reversing gear. Pressing the pressure plate causes the drive rack to move downward, which in turn causes the reversing gear to rotate. The rotation of the reversing gear causes the driven rack to drive the latch, which then inserts into the latch slot. This allows the device to quickly engage, greatly improving the ease of operation.

[0004] However, in the existing technology, the drive rack and driven rack are set on both sides of the reversing gear, which makes the snap-fit ​​structure occupy a large space; and the drive rack is moved by pressing the pressure plate, but the pressure plate lacks a limiting mechanism, which can easily cause accidental contact during the use of the equipment, causing the pressure plate to press down and the snap-fit ​​hook to be released, thus affecting the use of the equipment. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a press-to-retract buckle structure to solve the problem that the buckle is easily accidentally activated and thus unlocked.

[0006] To achieve the above objectives, this utility model provides a press-to-retract buckle structure, including a mounting box with a cover. The mounting box has symmetrical sliding openings on both sides. A button rod is longitudinally slidable inside the mounting box, with both ends of the button rod passing through the sliding openings on both sides. An inward-slidable rod is laterally slidable inside the mounting box, located below the button rod. One end of the inward-slidable rod is fixedly connected to an insert block. One end of the mounting box has a telescopic opening through which the insert block extends. A transmission mechanism is provided between the button rod and the inward-slidable rod, allowing the button rod to drive the inward-slidable rod and thus the locking block to extend and retract. A locking mechanism is provided at one end of the button rod to lock the button rod.

[0007] A further improvement is that the transmission mechanism includes a gear mounted inside the mounting box via a rotating shaft, a first rack mounted on one side of the button lever, and a second rack mounted on one side of the retractable rod, both of which mesh with the gear.

[0008] A further improvement is that a return spring is connected between the other end of the retractable rod and the inner wall of the mounting box.

[0009] A further improvement is that the locking mechanism includes a locking block, and mounting grooves are provided on both sides of the end of the button rod. The locking block is slidably installed in the mounting groove, and a pressing spring is provided between the locking block and the inside of the mounting groove.

[0010] A further improvement is that a guide groove is provided on the inner wall of the mounting groove, and a guide block is connected to the end of the locking block, with the guide block and the guide groove being adapted to each other.

[0011] A further improvement is that a limiting block is fixedly connected to the upper side of one end of the insert block inside the mounting box, and the extension of the insert block is limited by the limiting block.

[0012] The beneficial effects of this utility model are as follows: by distributing the button rod and the retractable rod alternately in the horizontal and vertical directions, and setting the gear at the corner where the button rod and the retractable rod intersect, a 90-degree retractable rod retractable component is formed, which effectively reduces the volume of the latch, realizes the retractable latch in a small space, and facilitates timely maintenance and replacement.

[0013] A locking mechanism is provided, in which locking blocks are installed on both sides of the button lever through mounting slots. The locking blocks extend from the mounting slots and abut against the side wall of the mounting box. The abutting between the locking blocks and the mounting box prevents the button lever from being pressed in the direction of the sliding opening, thereby locking the button lever, reducing the occurrence of accidental pressing to unlock, and improving the stability of use.

[0022] like Figure 1 , Figure 2 As shown, this utility model provides a press-to-retract buckle structure, including a mounting box 1, a box cover 2 on the mounting box 1, and the mounting box 1 and the box strap locked by bolts; the mounting box 1 has symmetrical sliding openings 3 on both sides, and a button rod 4 is longitudinally slidably arranged inside the mounting box 1, with both ends of the button rod 4 passing through the sliding openings 3 on both sides. By pressing the button rod 4, the button rod 4 slides between the sliding openings 3 on both sides; an inward retracting rod 5 is laterally slidably arranged inside the mounting box 1, located below the button rod 4, with a plug 6 fixedly connected to one end of the inward retracting rod 5, and a telescopic opening 7 opened at one end of the mounting box 1, through which the plug 6 extends out, and a return spring 11 is connected between the other end of the inward retracting rod 5 and the inner wall of the mounting box 1.

[0023] As shown in the figure, a transmission mechanism is provided between the button lever 4 and the retractable lever 5. The button lever 4 drives the retractable lever 5 through the transmission mechanism to extend and retract the locking block 12. The transmission mechanism includes a gear 8 that is rotatably mounted inside the mounting box 1 via a rotating shaft. A first rack 9 is mounted on one side of the button lever 4, and a second rack 10 is mounted on one side of the retractable lever 5. Both the first rack 9 and the second rack 10 mesh with the gear 8. By pressing the button lever 4, the first rack 9 drives the gear 8 to rotate. The rotation of the gear 8 causes the second rack 10 to move the retractable lever 5. The movement of the retractable lever 5 causes the insert 6 to retract from the telescopic opening 7 into the mounting box 1, thereby unlocking the latch. When the insert 6 needs to be locked, the button lever 4 is released. The return spring 11 pushes the retractable lever 5 in the opposite direction, causing the insert 6 to extend outward from the telescopic opening 7 to lock. The movement of the retractable lever 5 causes the second rack 10 to drive the gear 8 to rotate. The rotation of the gear 8 causes the first rack 9 to move and reset the button lever 4.

[0024] The upper side of one end of the insert 6 located inside the mounting box 1 is fixedly connected to a limiting block 17. As the inner retraction rod 5 drives the insert 6 to extend from the telescopic port 7, the limiting block 17 fits against the inner wall of the mounting box 1. The limiting block 17 limits the distance that the insert 6 extends outward from the telescopic port 7.

[0025] like Figure 3 As shown, a locking mechanism is provided at one end of the button lever 4 to lock the button lever 4. The locking mechanism includes a locking block 12. Mounting grooves 13 are provided on both sides of the end of the button lever 4. The locking block 12 is slidably installed in the mounting grooves 13, extending out of the mounting grooves 13, and its end is attached to the outer wall of the mounting box 1. The contact between the locking block 12 and the mounting box 1 prevents the button lever 4 from being pressed and slid, thus reducing the occurrence of accidental pressing of the button lever 4 and unlocking the insert 6. A guide groove 15 is provided on the inner wall of the mounting groove 13. A guide block 16 is connected to the end of the locking block 12. The guide block 16 is adapted to the guide groove 15. Through the cooperation of the guide block 16 and the guide groove 15, the locking block 12 is guided and slids within the mounting groove 13, ensuring stable sliding within the mounting groove 13. A pressing spring 14 is provided between the locking block 12 and the mounting groove 13. After the button lever 4 is released and reset, the sliding port 3 releases the limit on the locking block 12, and the pressing spring 14 pushes the locking block 12 out of the mounting groove 13 to lock the button lever 4.

[0026] A stop is provided at the other end of the button lever 4. The stop limits the movement of the button lever 4 to prevent the button lever 4 from sliding excessively and disengaging from the sliding port 3.

[0027] When in use, to unlock, press the locking blocks 12 on both sides to retract them into the mounting groove 13, releasing the restriction on the button lever 4. The button lever 4 then slides within the sliding opening 3. The inner wall of the sliding opening 3 restricts the locking blocks 12, preventing them from extending out of the mounting groove 13. The button lever 4 moves the first rack 9, driving the gear 8 to rotate. The second rack 10, along with the gear 8, moves the retracting rod 5. The movement of the retracting rod 5 causes the insert 6 to retract into the mounting box 1, and the return spring 11 to contract. To lock, release the locking mechanism. When the button lever 4 is pushed, the reset spring 11 pushes the retracting rod 5 in the opposite direction, causing the insert 6 to extend outward. The second rack 10 drives the gear 8 to rotate in the opposite direction. The first rack 9, along with the gear 8, drives the button lever 4 to move and reset. After the button lever 4 moves and resets, the locking block 12 moves out of the sliding port 3 along with the button lever 4. The sliding port 3 releases the restriction on the locking block 12. The locking block 12 extends out of the mounting groove 13 and fits against the outer wall of the mounting box 1 through the action of the pressing spring 14. The locking block 12 limits the button lever 4, preventing the button lever 4 from being pressed and reducing the occurrence of accidental pressing.
