[0002] At present, most lithium battery energy storage cabinets use a pull-rod type top and bottom lock (i.e., a three-point top, middle and bottom lock) to lock the door and the cabinet. The contact force between the door and the cabinet is adjusted by a plastic roller on the top of the pull rod, but the contact surface between the roller and the cabinet is a right-angle transition. This creates a disadvantage, that is, the matching accuracy requirements between the cabinet door and the cabinet are relatively high. If there is a slight deviation, the roller cannot reach the specified position, and the cabinet door and the cabinet cannot be closed; or the roller cannot reach the specified position due to the limitation of the cabinet, resulting in the inability to close the cabinet door and the cabinet.

[0003] In addition, the energy storage cabinet itself is welded, and the deformation is relatively large.

[0025] Embodiment

[0026] Please refer to Figures 1 - 6 as shown.

[0027] The present utility model provides a door lock device based on a storage cabinet body 1, such as Figure 1 , Figure 2As shown in the figure, the main problem to be solved is that in the prior art, when the door lock device is locked, the limiting structure is not easily affected by the cabinet body 1 and is not easily locked. As a result, in the assembly of many cabinet bodies 1, the door lock is not tight or cannot be latched, and the operation is complex. To solve the above problems, the technical solution of the present invention includes a pull rod 7 provided on the inner side wall of the cabinet door 2. The provided pull rod 7 is made of high-quality steel plate by laser cutting and has relatively high strength. A control component for controlling the vertical movement of the pull rod 7 is provided on the outer side of the cabinet door 2, and a guiding member for guiding the vertical movement of the pull rod 7 is provided on the inner side of the cabinet door 2. A limiting portion 5 is provided at the top of the cabinet body 1, and a lock body adapted to the limiting portion 5 is provided at the free end of the pull rod 7. Through the above structure, the pull rod 7 can be pushed to make the lock body move up and down along with the cabinet door 2 and be inserted into the limiting space formed by the limiting portion 5 and the top of the cabinet body 1. An inclined surface for guiding the cooperation between the lock body and the limiting portion 5 is provided on the side wall of the limiting portion 5 facing away from the cabinet door 2. The provided inclined surface facilitates the lock body to enter the limiting space formed by the limiting portion 5 and the top of the cabinet body 1, and avoids problems such as jamming or inability to enter when the lock body enters this limiting space and contacts the limiting portion 5. The included angle between the reverse extension line of the inclined surface and the axis of the pull rod 7 is an acute angle after they intersect, which can enable the lock body to smoothly transition into the limiting space formed by the limiting portion 5 and the top of the cabinet body 1 under the push of the pull rod 7, and improve the smoothness when the cabinet door 2 is locked.

[0028] Preferably, the pull rod 7 is composed of two sections of sleeves 14, and one of the sleeves 14 is sleeved inside the other sleeve 14. A plurality of round holes are provided on the outer wall of one of the sleeves 14, and countersunk screws threadedly connected therewith are provided in the round holes. The countersunk screws penetrate through the other sleeve 14, so that the length of the pull rod 7 can be adjusted, and the application range of this structure can be increased.

[0029] In some technical solutions of the present invention, the guiding member includes a plurality of guiding sleeves 8. The guiding sleeves 8 are fixed on the inner wall of the cabinet door 2, and the pull rod 7 is sleeved inside the guiding sleeves 8. The material of the guiding sleeves 8 is processed from ABS plastic, which can reduce the friction when the pull rod 7 moves, and at the same time prevent the pull rod 7 from undergoing lateral deformation due to its slenderness, ensuring that the lock rod has relatively high rigidity. Providing at least 3 guiding sleeves 8 can ensure the movement accuracy and rigidity of the pull rod 7 and meet the design requirements when the door lock moves up and down.

[0030] In some technical solutions of the present utility model, the control assembly includes a handle. An installation opening is provided on the cabinet door 2, and the handle is rotatably arranged in the installation opening. The handle and the pull rod 7 are arranged on both sides of the cabinet door 2 in a staggered manner. An adjusting arm 13 is rotatably provided in the middle of the pull rod 7, and the free end of the adjusting arm 13 is connected to the handle. The rotating handle is rotatably arranged in the installation opening through a bearing. Since the handle and the pull rod 7 are arranged in a staggered manner, when the handle is rotated, the handle will drive the adjusting arm 13 to make a circular motion on the cabinet door 2, and at the same time, a thrust will be applied to the pull rod 7 hinged to the adjusting arm 13, forcing the pull rod 7 to move in a straight line along the vertical direction attached to the cabinet door 2 under the guidance of the guiding member, realizing the operation of closing or opening the door. The handle moves upward to open the door, and the handle moves downward to close the door.

[0031] In some technical solutions of the present utility model, the lock body includes an L-shaped lock rod head 4, and the lock rod head 4 is installed on the free end of the pull rod 7. The lock rod head 4 is threadedly connected to the pull rod 7. A locking wheel 6 is rotatably provided on the free end of the lock rod head 4, which is convenient for reducing the friction between the lock rod head 4 and the inclined surface provided on the limiting portion 5 when the lock rod head 4 contacts the inclined surface, so that the lock body can smoothly transition into the limiting space formed by the limiting portion 5 and the top of the cabinet body 1 under the push of the pull rod 7, improving the smoothness when the cabinet door 2 is locked.

[0032] Preferably, the provided L-shaped lock rod head 4 also has a certain elasticity, and its vertical end for installing the locking wheel 6 can tilt relative to the horizontal section connected to the pull rod 7 at a certain angle.

[0033] In some technical solutions of the present utility model, a locking component for locking the locking wheel 6 is provided at the top of the cabinet body 1.

[0034] In some technical solutions of the present utility model, the locking component includes a mounting seat 9 provided on the side wall of the limiting portion 5 facing away from the cabinet door 2. An installation channel is provided in the mounting seat 9, and a push rod 11 is slidably arranged in the installation channel. One end of the push rod 11 protrudes from the installation channel. A limiting spring 12 connected to the installation channel is sleeved on the push rod 11. A plurality of locking openings are provided on the outer circumferential wall of the locking wheel 6, and a part of the push rod 11 is embedded in the locking openings. The provided locking component can lock the locking wheel 6 in the limiting space formed by the limiting portion 5 and the top of the cabinet body 1, improving the closing ability of the cabinet door 2 and the cabinet body 1. When the locking wheel 6 is gradually pushed by the pull rod 7 and placed in the limiting space formed by the limiting portion 5 and the top of the cabinet body 1, the locking wheel 6 will gradually squeeze the arc-shaped push rod 11 arranged in the arc-shaped installation channel, and the other end of the arc-shaped push rod 11 will gradually withdraw from the installation channel and then be embedded in the locking opening to lock the locking wheel 6. The provided limiting spring 12 enables the end of the push rod 11 extending out of the installation channel to gradually retract into the installation channel after the push rod 11 is not squeezed by the locking wheel 6 in the installation channel.

[0035] In some technical solutions of the present utility model, an installation groove is radially formed along the pull rod 7 at the free end of the lock rod head 4, and a locking wheel 6 is rotatably arranged in the installation groove. In this way, the locking wheel 6 has a retraction space on the lock rod head 4, so that in the early stage when the locking wheel 6 contacts the inclined surface provided on the limiting portion 5, it can smoothly transition into the limiting space formed by the limiting portion 5 and the top of the cabinet body 1.

[0036] Preferably, a pressure spring 10 abutting against the locking wheel 6 is arranged in the installation groove, so that the locking wheel 6 cannot move randomly in the installation groove, thereby improving the closing ability of the cabinet door 2 and the cabinet body 1 of this structure.

[0037] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
