Detailed Description

Referring to fig. 1 to 13, an embodiment of the present invention relates to a door lock structure for use between a box 1 and a double door 2. The double door 2 comprises a first door 21 and a second door 22 which are distributed in sequence, and the first door 21 and the second door 22 are respectively and rotatably arranged on the opening of the box body 1. The first door 21 is provided with a first lock catch 211, and the second door 22 is provided with a second lock catch 221.

Referring to fig. 4 to 7, the door lock structure includes a door lock main body 31, a first main body buckle 311 disposed on the door lock main body 31, and a second main body buckle 312 disposed on the door lock main body 31. The door lock body 31 is adapted to be slidably disposed between a locking position and an unlocking position on the box body 1, that is, the first body lock 311 is adapted to be locked in cooperation with the first lock catch 211 on the first door 21 at the locking position; the second body lock 312 is disposed on the door lock body 31 and adapted to be locked with the second lock catch 221 on the second door 22 at a locking position; and in the unlocking position, the first main body lock 311 and the second main body lock 312 are separated from the first lock 211 and the second lock 221, respectively.

Referring to fig. 7 and 9, the first body buckle 311 has a first arc surface 3111 or the first lock buckle 211 has a first arc surface 2111, and the first body buckle 311 and the first lock buckle 211 are guided by the first arc surface 3111/2111 such that the first lock buckle 211 is clamped on the first body buckle 311; the second circular arc surface 3121 is provided on the second main body buckle 312 or the second lock catch 221 is provided with a second circular arc surface 2211, and the second lock catch 221 is clamped on the second main body buckle 312 by the guide of the second circular arc surface 3121/2211 between the second main body buckle 312 and the second lock catch 221.

The door lock structure further includes a driving mechanism for driving the door lock main body 31 to reciprocate between the locked position and the unlocked position.

Referring to fig. 4 to 9, the driving mechanism includes a transmission assembly 3, and the transmission assembly 3 is driven by a driving force to reciprocate so as to drive the door lock main body 31 to reciprocate in a linkage manner. The transmission assembly 3 includes at least a first rack 331 and a gear 32. The first rack 331 is fixedly connected to the door lock main body 31 and extends along the moving direction of the door lock main body 31; the gear 32 is rotatably disposed on the case 1, the number of the gears 32 is at least one, and the gears are engaged with the first rack 331, and the gears 32 are driven by a driving force to drive the first rack 331 to reciprocate.

Referring to fig. 8 and 9, the number of the gears 32 is not only at least one, but also the number of the gears 32 is limited to an odd number, and it is only necessary that the driving force is applied to the gears 32 to drive the first rack 331 to reciprocate.

With continued reference to fig. 8 and 9, in a first preferred embodiment of the present invention, the number of the gears 32 is three, including a first gear 321, a second gear 322, and a transition gear 323. In this case, the transmission assembly 3 further includes a second rack 332 slidably disposed on the box 1, and a sliding direction of the second rack 332 is perpendicular to a sliding direction of the first rack 331.

The first gear 321 comprises a first toothed surface 3210 engaged with the first toothed rack 331 (conversely, the first toothed rack 331 has a third toothed surface 3310 engaged with the first toothed surface 3210), the second gear 322 comprises a second toothed surface 3220 engaged with the second toothed rack 332 (conversely, the second toothed rack 332 has a fourth toothed surface 3320 engaged with the second toothed surface 3220), so that the first gear 321 is engaged with the first toothed rack 331 and the second gear 322 is engaged with the second toothed rack 332. The first gear 321 and the second gear 322 are not directly matched, and the meshing transmission between the first gear 321 and the second gear 322 is realized through a transition gear 323 between the first gear 321 and the second gear 322. Since the extending and sliding directions of the first and

second racks

331 and 332 are vertical, the transmission assembly 3 achieves the steering of the driving force from the horizontal direction to the vertical direction.

In a second embodiment of the present invention, which is not shown in the drawings, only one first gear 321 and one first rack 331 may be provided instead of the second rack 332, the second gear 322, and the transition gear 323 described in the first embodiment, and as long as the driving force can drive the first gear 321 to rotate on the other side, the rotation of the first gear 321 can further drive the door lock main body 31 to reciprocate by the meshing relationship between the first gear 321 and the first rack 331.

In the second embodiment, the driving force is located at the left side of the first gear 321, the driving force downwards makes the first gear 321 rotate anticlockwise, and the first gear 321 drives the door lock main body 31 to move upwards to open the double door 2.

Of course, in another embodiment not shown, the number of the transition gears 323 may be a plurality and an odd number, for example: the number of the transition gears 323 is three, but in the other embodiments, the number of the transition gears 323 is increased, only intermediate transmission steps are added, substantially the same transmission effect is achieved, and the technical effect of simple structure is not achieved, so that the other embodiments of the plurality of transition gears 323 are not the preferred embodiment of the present invention.

Referring to fig. 1, 12 and 13, the driving mechanism further includes a button member 4 telescopically disposed on an outer wall of the first door 21 or the second door 22. The button member 4 is connected to the second rack gear 332, and by pressing the button member 4 to push the second rack gear 332 to move in the lateral direction, the door lock main body 31 is driven to move in the vertical direction toward the unlock position. That is, the push button 4 is the position where the driving force is applied in the present invention, and the user presses the push button 4 to provide the driving force necessary for the rotation of the gear 32. Of course, the button member 4 is an embodiment adapted to three gears 32; in other embodiments, for example: in the case of one and only one gear 32, the button member 4 can be replaced by a slide member that slides up and down, and slides down to turn the gear 32 and thus move the door lock body 31 vertically toward the unlocking position.

Referring to fig. 8 and 9, the door lock structure of the present invention further includes a door lock box 35 fixed on the box body 1 and having a receiving cavity; the drive mechanism further includes a reset element 34 and a door pop-up device 36. The door lock main body 31, the transmission assembly 3, the reset element 34 and the door springing device 36 are all accommodated in the accommodating cavity of the door lock box 35. The door lock case 35 functions to provide a space for movement of the door lock body 31, the driving assembly 3, the reset element 34 and the door pop-up device 36, thereby ensuring that the door lock body 31, the driving assembly 3, the reset element 34 and the door pop-up device 36 move within a specific trajectory without deviating from the trajectory.

Referring to fig. 8 and 9, the reset element 34 is disposed between the door lock main body 31 and the box body 1, and applies a reset force to the door lock main body 31, and the door lock main body 31 is driven by the reset force and tends to be kept in the locked position. In the present invention, the reset element 34 is located above the door lock body 31, thereby providing an elastic reset force against the door lock body 31 downward.

Referring to fig. 4, 8 and 9, one end of the door pop-up device 36 abuts against the inner wall of the door lock box 35, and the other end abuts against the inner side of the first door 21 or the second door 22, so as to apply a biasing force to the first door 21 or the second door 22, and drive the first door 21 and the second door 22 to pop-up from the opening of the box body 1 in an unlocked state. In the present invention, the door lock body 31 is vertically installed on the door lock case 35, and the door pop-up device 36 is horizontally installed at the bottom of the door lock case 35.

Referring to fig. 4 and 9, the door pop-up device 36 includes a housing 361 and an elastic member 362 embedded in the housing 361, and an outer end of the housing 361 tends to abut against the first door 21 or the second door 22 under the urging force of the elastic member 362. The return element 34 also comprises a housing 341 and a coil spring 342 housed by the housing 341, the top of the housing 341 being urged against the inner top wall of the door-lock case 35 by the biasing force of the coil spring 342. The outer case 341 and the case 361 are not necessary, and the restoring effect can be realized only by the coil spring 342 and the door opening effect can be realized only by the elastic element 362.

Referring to fig. 8 and 9, the receiving chamber has a first receiving chamber 351 for limiting the sliding of the door lock main body 31, the returning member 34 and the first rack 331. The upper side of the first accommodating cavity 351 has an upper partition wall 3511, and the lower side of the first accommodating cavity 351 has a middle partition wall 3512, so that when the reset element 34 is vertically mounted and abutted on the upper side of the door lock main body 31 and the first rack 331 is vertically mounted and abutted on the lower side of the door lock main body 31, the top of the reset element 34 can be separated from or abutted against the upper partition wall 3511, and the bottom of the first rack 331 can be abutted against or separated from the middle partition wall 3512, that is: in the locked position, the door lock body 31 is in the low position and abuts against the middle partition 3512 via the first rack 331, but the reset element 34 is separated from the upper partition 3511, and in the unlocked position, the door lock body 31 is in the high position and abuts against the upper partition 3511 via the reset element 34, but the bottom of the first rack 331 is separated from the middle partition 3512. Particular emphasis is given to: since the first gear 321 is located at the left side, when the first rack 331 is installed in the door lock case 35, the third toothed surface 3310 needs to be installed to face the first gear 321 to enable the engagement between the first rack 331 and the first gear 321.

Referring to fig. 8 and 9, the accommodating chamber further includes a lower partition 3513 spaced below the middle partition 3512. When the second rack gear 332 is mounted in the door lock case 35 in a state where the fourth tooth pattern surface 3320 faces upward and faces the second gear 322 in the lateral direction, the side of the second rack gear 332 facing away from the fourth tooth pattern surface 3320 abuts against the lower blocking wall 3513. The second rack 332 can slide laterally above the lower retaining wall 3513.

It should be noted that: the middle partition plate 3512 is not necessary in the present invention, and if the length of the first rack 331 is lengthened to the low position, the first rack 331 directly abuts against the lower partition wall 3513, and the effect that the first rack 331 moves to drive the door lock main body 31 to move upward to the high position to abut against the reset element 34 can also be achieved, at this time, only the lengths of the first rack 331 and the second rack 332 need to be set, so that the vertically extending first rack 331 and the horizontally extending second rack 332 do not interfere with each other.

With continued reference to fig. 8 and 9, the door lock box 35 has a first slot 3514 and a second slot 3515 located on the same side and below the first slot 3514 on the left side wall forming the first accommodating cavity 351, so that the first body buckle 311 and the second body buckle 312 both extend toward the front of the double door 2. In the embodiment, the first body lock 311 extends forward out of the door lock body 31 to be able to engage with the first lock catch 211 of the first door 21, and the second body lock 312 extends forward but does not extend out of the door lock body 31, but the second lock catch 221 of the second door 22 protrudes into the inner space of the door lock body 31 to engage with the door lock body 31. Of course, whether the first body lock 311 and the second body lock 312 extend out of the door lock body 31 is not limited as long as they can be engaged with the corresponding first lock 211 and second lock 221. The second slot 3515 penetrates downward to a position where the second rack gear 332 is located, so the second slot 3515 can also enable the button member 4 to pass through the second door 22 in the double door 2 to abut against the second rack gear 332.

Referring to fig. 8 and 9, further, a second accommodating chamber 352 for limiting the sliding of the door pop-up device 36 is disposed below the lower partition 3513. The second accommodating cavity 352 is opened toward the front of the double door 2, such that the front end of the door pop-up device 36 abuts against the second door 22, and thus, in the locked position, the second door 22 abuts against the door pop-up device 36 and compresses the elastic element 362 in the door pop-up device 36 to the right; in the process of unlocking the first body latch 311 and the first latch 211 and unlocking the second body latch 312 and the second latch 221, the elastic force of the elastic element 362 in the door opening device 36 is released to open the second door 22, so as to drive the first door 21 to open in a linkage manner.

With continued reference to fig. 8 and 9, further, the door lock box 35 further has a plurality of third receiving cavities 353 for positioning the gear 32, i.e., the first gear 321, the second gear 322 and the transition gear 323. The third accommodating cavity 353 is formed by surrounding a plurality of arc-shaped blocking walls according to the shapes of the first gear 321, the second gear 322 and the transition gear 323; a convex column for positioning and installing the gear 32 is arranged in each third accommodating cavity 353 in a protruding manner, and is used for correspondingly installing the first gear 321, the second gear 322 and the transition gear 323 respectively.

The three gears 32 are provided to achieve the transformation of the meshing transmission direction between the first gear 321 and the second gear 322 through the transition gear 323, that is, the horizontal force exerted by the button 4 on the second rack 332 is transformed into the vertical force exerted on the first rack 331, and then the connection is established between the button 4 and the door lock main body 31, that is, in the unlocking process, the user can operate the button 4 to drive the door lock main body 31 to move upwards to open the double door 2.

Referring to fig. 4 to 10, the present invention includes a linkage mechanism 6 for linking the first door 21, the second door 22 and the side wall of the cabinet 1, so as to force the first door 21 and the second door 22 to rotate synchronously.
