[0002] There are two common structural forms for the cabinet door lock of a double-leaf door cabinet: the first one is to use a single-side door lock, that is, a connecting rod lock is installed on the right door, and in order to realize effective locking, a limiting side plate is welded on the left door; when locking, the left door is closed first, and then the right door is closed, the right door is pressed on the limiting side plate of the left door, and then the right door is locked with the cabinet by the connecting rod lock on the right door. The second one is to install a flat lock on the right door, and spring pins are installed on the upper and lower ends of the left door, when locking, the left door is closed first, and then the left door and the cabinet are fixed by the spring pins, and then the right door is closed, and the right door is locked with the left door by the flat lock on the right door.

[0003] The first cabinet door lock has a simple structure, but since the limiting side plate is welded on the left door, the processing is relatively complex and the appearance is poor; after the right door is opened, the left door loses the constraint and is easy to swing, which may cause harm to the external staff. The second cabinet door lock can ensure the separate control of the left and right doors, but the opening and closing operations are relatively complex, and the use is not convenient. SUMMARY

[0004] The purpose of the present application is to provide a cabinet door limiting locking mechanism, which can not only realize the separate control of the left and right cabinet doors and avoid the swinging of the cabinet door losing the constraint, but also has a simple structure and is convenient to operate, and during the closing of the cabinet door provided with the flat lock, the mechanism can lock the other cabinet door, thereby solving the above technical problems.

[0005] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows: a cabinet door limiting locking mechanism, comprising a box body and a mounting structure, the box body is connected with the mounting structure, and the mounting structure is used for connecting with the cabinet door; a locking assembly and a limiting assembly are arranged in the box body;

[0008] The beneficial effects are that the lock tongue in the locking component is linked with the lock pin, when the mechanism is installed on the left cabinet door, the right cabinet door can be pressed to retract the lock tongue, the lock pin is pushed out to be clamped on the cabinet body through the connecting rod to lock the left cabinet door; at the same time, the limiting pin of the limiting component is clamped into the limiting slot on the side of the lock tongue to prevent the lock tongue from being ejected, so that the left cabinet door is always in the locked state regardless of whether the right cabinet door is closed or opened, and the left cabinet door will not swing freely to avoid hurting people; when the left cabinet door needs to be opened, the limiting of the lock tongue by the limiting pin can be released through the control member, the lock tongue is ejected by the second spring, the lock pin is retracted through the connecting rod to release the locking of the left cabinet door. Therefore, after adopting the mechanism, when the planar lock is used on the right cabinet door, it is not necessary to weld the limiting side plate on the left cabinet door, nor is it necessary to install the ordinary spring pin which is not aesthetic on the left cabinet door, and the opening and closing state of the left cabinet door can be flexibly controlled.

[0009] Further, the control member is a moving plate and a pressing marble on the outer end of the moving plate, the moving plate is slidingly installed in the notch slot of the limiting pin, and the side of the moving plate in contact with the root of the notch slot is provided with an inclined surface, and the pressing marble is exposed from the marble hole to the box body.

[0010] The beneficial effects are that the pressing action can be converted into the movement of the limiting pin through the inclined surface of the moving plate to retract the limiting pin and release the limiting of the lock tongue.

[0011] Further, the thickness of the moving plate is adapted to the width of the notch slot, and the width of the moving plate is greater than the diameter of the marble hole.

[0012] The beneficial effects are that the thickness of the moving plate is adapted to the width of the notch slot to make the movement of the moving plate more stable, and the width of the moving plate being greater than the diameter of the marble hole can avoid the failure of the limiting effect caused by the moving plate being separated from the box body.

[0013] As an alternative to the moving plate and the pressing marble, the control member is a lever, one end of the lever is connected with the limiting pin, and the other end is exposed from the sliding slot on the side of the box body.

[0017] The tail end of the lock tongue is provided with a positioning column, and the second spring is installed on the positioning column.

[0018] The beneficial effect is that the positioning column can constrain the end of the spring, ensuring the stability of the spring extension and retraction.

[0019] The lock tongue is installed in a lock tongue sliding groove, the lock pin is installed in a lock pin sliding groove, the lock pin sliding groove is provided with two and symmetrically distributed on both sides of the lock tongue sliding groove; the limiting component installation slot is provided with two and symmetrically distributed on both sides of the lock tongue sliding groove.

[0020] The beneficial effect is that the symmetrical arrangement of the lock pin sliding groove can meet the locking requirements of the box body installed on the upper end and the lower end of the cabinet door, so that after the box body is installed, the lock pin located at the top of the cabinet door can slide upward to play a locking role, and the lock pin located at the bottom of the cabinet door can slide downward to play a locking role; the symmetrical arrangement of the limiting component installation slot facilitates the installation of the limiting component on the side convenient for manual operation according to the different installation positions of the box body.

[0021] The box body comprises a lower box body and a box cover, the locking assembly and the limiting component are arranged in the lower box body, and the box cover is fixed on the lower box body.

[0022] The beneficial effect is that the box body and the corresponding components can be quickly assembled.

[0046] As a variation, positioning guide posts can be set on the lid, and positioning holes or positioning grooves can be set on the lower box body, which can also serve the purpose of positioning and assembly.

[0047] The mounting structure 5 comprises a mounting plate provided with connecting buckles 501 and mounting buckles 502, the connecting buckles 501 are provided with two columnar mushroom head structures, a through hole 2107 matched with the connecting buckles 501 is arranged on the lower box body 21, the connecting buckles 501 are strongly matched with the through hole 2107 to realize the connection of the box body 2 and the mounting plate; the mounting buckles 502 are provided with two, which are respectively arranged at two edges of the mounting plate in different directions, a clamping groove matched with the mounting buckles 502 is arranged on the cabinet door to realize the quick mounting of the whole mechanism on the cabinet door.

[0048] With reference to the drawings Figure 2 As shown, the mounting groove in the lower box body 21 comprises a lock tongue sliding groove 2101 and a spring groove 2103 arranged at the middle part of the lower box body 21, the lock tongue sliding groove 2101 and the spring groove 2103 are in the same straight line, the lock tongue sliding groove 2101 is open at the side of the lower box body 21, two symmetrical lock pin sliding grooves 2102 and two symmetrical limiting component mounting grooves 2104 are arranged at the two sides of the lock tongue sliding groove 2101 and the spring groove 2103. The lock tongue sliding groove 2101, the spring groove 2103 and the lock pin sliding groove 2102 at one side thereof are used for mounting the locking assembly 4; the limiting component mounting groove 2104 at one side thereof is used for mounting the limiting component 3. The selection of the lock pin sliding groove 2102 and the limiting component mounting groove 2104 needs to be determined according to the mounting position of the box body 2 on the cabinet door.

[0049] As Figure 4As shown, the locking assembly 4 includes a latch 41, a connecting rod 42, a locking pin 43, and a second spring 44. A positioning post 4103 is provided at the tail end of the latch 41, and the end of the second spring 44 is fitted onto the positioning post 4103 to ensure the stability of the second spring 44 during extension and retraction. The latch 41 and the second spring 44 are respectively installed in the latch slide groove 2101 and the spring groove 2103. One end of the second spring 44 abuts against the tail end of the latch 41, and the other end abuts against the inner wall of the spring groove 2103. When the latch 41 is not subjected to external force, the second spring 44 pushes the front end of the latch 41 out of the latch slide groove 2101.
