[0031] Please refer to Figure 1 and Figure 2 , the present utility model provides a door lock catch 100, which is applied to a storage box 1000. The storage box 1000 includes a box body 200 and a box door 300. One side of the box body 200 is provided with an opening. A card slot 220 is provided at a position on the side wall of the box body 200 close to the opening. The box door 300 covers the opening. An installation opening 310 penetrates through the box door 300. The door lock catch 100 includes a first elastic arm 10 and a second elastic arm 20. Wherein, one end of the first elastic arm 10 is integrally formed and connected to one end of the second elastic arm 20. One end of the first elastic arm 10 is spaced from the other end of the second elastic arm 20. A first fixing portion 13 is provided at the other end of the first elastic arm 10. A second fixing portion 23 and a clamping portion 24 are provided at the other end of the second elastic arm 20. The first fixing portion 13 and the second fixing portion 23 are respectively used for clamping the opposite side edges of the installation opening 310. The clamping portion 24 is used for clamping the card slot 220.
[0032] With the above solution of the present utility model, during assembly, one of the first fixing portion 13 and the second fixing portion 23 can be snapped onto the periphery of the mounting opening 310 first, and then the first elastic arm 10 or the second elastic arm 20 is pressed, so that the first fixing portion 13 and the second fixing portion 23 approach each other, thereby facilitating the alignment and snapping of the other of the first fixing portion 13 and the second fixing portion 23 with the periphery of the mounting opening 310. In this way, the installation and fixation are completely achieved by utilizing the elasticity of the door lock catch 100 itself. The door lock catch 100 adopts an integral structure to reduce the number of parts and assembly steps and lower the assembly cost.
[0033] The engaging portion 24 of the door lock catch 100 installed on the door 300 is snapped into the engaging groove 220 of the box body 200. When it is necessary to open the door 300, the first elastic arm 10 or the second elastic arm 20 is also pressed in the same way, so that the engaging portion 24 withdraws from the engaging groove 220, thereby opening the door 300.
[0034] The first elastic arm 10 and the second elastic arm 20 can be connected to form a U shape, or can be set as a V shape, which is not limited herein.
[0035] The above-mentioned first fixing portion 13 can be arranged at any position at the end of the first elastic arm 10. It can be on the side of the first elastic arm 10 close to the second elastic arm 20, or on the opposite sides of the first elastic arm 10. There are also various specific implementation manners for the first fixing portion 13 to be snapped onto the mounting opening 310. In some embodiments of the present utility model, two hooks are arranged on the opposite sides of the first fixing portion 13, and the two hooks are respectively snapped onto the opposite sides of the periphery of the mounting opening 310 away from the second elastic arm 20. In some other embodiments of the present utility model, the first fixing portion 13 is arranged on the side of the first elastic arm 10 away from the second elastic arm 20, and a snap-in opening 131 is recessed in the first fixing portion 13 for snapping onto the periphery of the mounting opening 310. In this way, during installation, the engaging groove 220 can be directly inserted into the periphery of the mounting opening 310, and the fixation is achieved by using the elastic tension between the first elastic arm 10 and the second elastic arm 20, which is convenient and fast.
[0036] In order to facilitate the snapping of the first fixing portion 13, in some embodiments of the present utility model, at least one side of the first fixing portion 13 in the extending direction of the first elastic arm 10 is provided with a guiding inclined surface 132, and the guiding inclined surface 132 inclines towards the direction close to the snap-in opening 131 in the protruding direction of the first fixing portion 13. In this way, during installation, the guiding inclined surface 132 can be abutted against the edge of the mounting opening 310, and then the door lock catch 100 can be directly pushed, so that the second fixing portion 23 and the edge of the mounting opening 310 move relative to each other along the inclined direction of the guiding inclined surface 132 until they are snapped together.
[0037] The above-mentioned guiding inclined surface 132 can be arranged on one side of the first fixing part 13 in the direction where the first elastic arm 10 is close to the second elastic arm 20, so that the door lock catch 100 can be pressed and installed outward from the inner side of the door 300; preferably, the guiding inclined surface 132 is arranged on the first fixing part 13 in the direction where the first elastic arm 10 is far from the second elastic arm 20, so that the door lock catch 100 can be pressed and installed inward from the outer side of the door 300, and the support of the box body 200 for the door 300 is utilized for installation, which is more convenient.
[0038] Further, in some embodiments of the present invention, the first elastic arm 10 includes a first main arm 11 and a first sub-arm 12. One end of the first main arm 11 is connected to the second elastic arm 20. One end of the first sub-arm 12 is connected to the end of the first main arm 11 far from the second elastic arm 20. The other end of the first sub-arm 12 is spaced from the first main arm 11 and is provided with a first fixing part 13. Similarly, the first sub-arm 12 and the first main arm 11 can be connected into a U shape or can be set as a V shape. Through the above solution, when one of the first main arm 11 and the first sub-arm 12 generates elastic fatigue, the other can make up for the elastic supporting force, thereby ensuring the clamping stability between the first fixing part 13 and the edge of the installation opening 310.
[0039] In some embodiments of the present invention, the second elastic arm 20 includes a second main arm 21 and a second sub-arm 22, and the second main arm 21 is formed with a second fixing part 23; in some embodiments of the present invention, the second sub-arm 22 is formed with a second fixing part 23; in some embodiments of the present invention, the second main arm 21 and the second sub-arm 22 are combined to form a second fixing part 23. The second fixing part 23 can also be clamped with the edge of the installation opening 310 through two hooks, or can be set as a limiting groove to be clamped with the edge of the installation opening 310. The specific implementation manner of the second fixing part 23 can be set according to the actual situation.
[0040] In some embodiments of the present invention, the second fixing part 23 is a limiting groove. One end of the second main arm 21 is connected to the first elastic arm 10. One end of the second sub-arm 22 is connected to the end of the second main arm 21 far from the first elastic arm 10 and encloses to form a limiting groove. A clamping part 24 is formed at the end of the second sub-arm 22 far from the second main arm 21. The limiting effect is better.
[0041] Further, in some embodiments of the present utility model, the second main arm 21 includes a pressing section 211 and an outer limiting section 212, and the pressing section 211 is connected between the outer limiting section 212 and the second elastic arm 20; the second sub-arm 22 includes a lower limiting section 221 and an inner limiting section 222, one end of the lower limiting section 221 is connected to one end of the outer limiting section 212 close to the pressing section 211, the inner limiting section 222 is connected to the end of the lower limiting section 221 away from the outer limiting section 212, and an limiting groove is formed by enclosing the lower limiting section 221 and the outer limiting section 212; the clamping portion 24 is a tongue, and the tongue is connected to the end of the inner limiting section 222 away from the lower limiting section 221, and the tongue is located on the side of the inner limiting section 222 facing away from the limiting groove and protrudes along the direction away from the first elastic arm 10. When the door lock catch 100 is installed into the installation opening 310, elastic limiting is respectively carried out through the outer limiting section 212, the lower limiting section 221 and the inner limiting section 222. When unlocking, the pressing section 211 is subjected to a pressing force, driving each limiting section and the tongue to move downward together until the tongue disengages from the clamping groove 220.
[0042] Further, in some embodiments of the present utility model, the pressing section 211 is arranged in an arc shape. In this way, it fits the human finger pulp and reduces the pressing pain.
[0043] Further, the surface of the pressing section 211 facing away from the first elastic arm 10 is provided with anti-slip patterns to increase the convenience of use.
[0044] In some embodiments of the present utility model, the inner limiting section 222 and the lower limiting section 221 are arranged at an acute angle, so that the end of the inner limiting section 222 abuts against the box door 300, and an avoidance space 26 is formed between the surface of the inner limiting section 222 and the box door 300. In this way, when pressing the pressing section 211, the pressing section 211 pulls the inner limiting section 222 through the lower limiting section 221, so that the inner limiting section 222 has a tendency to move outwards. Due to the existence of the avoidance space 26, it is avoided that the inner limiting section 222 is limited by the edge of the installation opening 310 and cannot move, increasing the convenience of unlocking.
[0045] In some embodiments of the present utility model, the second sub-arm 22 further includes a rib plate 25, and the rib plate 25 is connected between the surface of the inner limiting section 222 away from the outer limiting section 212 and the clamping portion 24.
