The high sealing door generally locks the cabinet door through a connecting rod, and the connecting rod lock needs to be installed with a guide piece, a positioning piece and the like locking fittings on the door plate, and a plurality of assembly steps are required to realize the locking action of the cabinet lock body. For example, the patent document CN 21392318197.2 discloses a container energy storage cabinet door, which is granted on October 15, 2021, and the utility model name is "a container energy storage cabinet door". The container energy storage cabinet door includes a door frame, the door frame includes side beams and cross beams connected in sequence through corner pieces, a side beam is rotatably connected with an outer door, the outer door is rotatably connected with an inner door, the outer door is detachably installed with a lock rod, the lock rod is provided with lock heads at both ends, the cross beam is fixed with a clamping block, the clamping block is provided with a notch, and the lock head can be fixed with the clamping block after penetrating the notch and rotating. However, the above-mentioned lock rod (connecting rod) is generally fixed through the plug-in mode of the top and bottom rods, which causes the jamming, the failure of the clamping point and the difficulty in pulling out or inserting, and the tension type locking and unlocking are less used. SUMMARY
[0003] In order to overcome the above-mentioned defects, the utility model aims to provide a container energy storage cabinet door tension type lock point device to solve the technical problems of the poor structure design of the lock point of the existing similar products, the jamming, the failure of the clamping point and the difficulty in pulling out or inserting. The purpose is realized through the following technical scheme.
[0004] A tensioning locking device for a container energy storage cabinet door, the main body of which is a tensioning locking assembly; its key structural design features include a locking rack on one side meshing with a locking gear inside the locking housing, one end of the locking rack hinged to one end of a first or third link of a connecting rod assembly, the connecting rod assembly being X-shaped, the first and third links on the upper and lower sides of the connecting rod assembly being connected and linked to the second link via a second connector of the connecting rod assembly, and the lock body being connected and linked to the second links on both sides via the first connector of the connecting rod assembly; the center hole of the locking gear is connected to the pin of a first bevel gear inside the locking cover, the first bevel gear meshing with a second bevel gear extending into the locking cover, and the locking cover being fixedly mounted at the locking point at the meshing point. At the end of the housing, the locking point housing is fixedly installed on the cabinet door or fixed plate. The pin shaft of the second bevel gear inside the locking point housing is connected to one end of the pressure rod inside the locking point housing through the rod sleeve. The pins extending from both sides of the pressure rod inside the locking point housing extend sequentially from the spiral sliding hole of the rod sleeve and the L-shaped sliding hole of the outer sleeve, respectively, and are installed inside the locking point housing. The other end of the pressure rod extends out of the locking point housing and is provided with a locking head. One end of the locking head is fixedly installed on the pressure rod, and the other end of the locking head protrudes outward in an arc shape. When the locking head is opened by the lock body and the connecting rod assembly, it retracts and presses against the fixed plate on the inside of the cabinet door. When the locking head is closed by the lock body and the connecting rod assembly, it extends and presses against the door frame of the cabinet body behind the fixed plate. The fixed plate is integrated with the cabinet door. One side of the cabinet door is opened or closed by a hinge set between the corresponding side door frame at the cabinet body. The above is a specific structural embodiment of a tension-type locking point assembly. The pressure rod and the rod sleeve are connected to each other, and the extension and rotation of the pressure rod and the locking point head are realized through the pins on both sides of the pressure rod and the corresponding spiral sliding holes and L-shaped sliding holes. The cam-type structure with an outward arc protrusion at the locking point head transitions the unlocking and locking process, improves the stability of the unlocking and locking process, and prevents jamming and difficulty in pulling out and inserting. The lock body moves up and down through the lock body rack, which drives the first connecting piece to move up and down and drives the corresponding connecting rod to move up and down in linkage. The corresponding connecting rod locking point head unlocks or locks the inner side of the cabinet door frame.
[0005] The cabinet door frame is equipped with a guide with an opening on one side. The locking heads of the tension-type locking assembly extend into or detach from the guide by extending and retracting the pressure rod. This further ensures a stable lock between the locking heads and the cabinet door frame when locked.
[0006] The locking rack and locking gear are placed in the groove corresponding to the locking housing below the second bevel gear. The second bevel gear meshes with the first bevel gear at a 90-degree angle and is disposed within the locking cover on one side of the locking housing. The above describes the specific structural arrangement of the main components within the tension-type locking assembly, thereby reducing space occupation and overall volume.
[0007] The length of the first link in the linkage assembly is greater than the length of the third link, and the length of the third link is greater than the length of the second link. Therefore, the corresponding lock body is located slightly below the center of the cabinet door, making lock operation relatively convenient.
[0008] The tension-type locking point assembly has four locking points symmetrically arranged vertically on the two side slots of the fixing plate on the inside of the cabinet door. Alternatively, the locking point connecting rod assembly on one side, along with the corresponding first connecting rod, second connecting rod, second connecting piece, and third connecting rod on that side, can be omitted. In other words, the locking point positions of the tension-type locking point assembly can be adjusted arbitrarily. Eliminating the two locking points on one side, with the omission of the corresponding components on the hinge side, is the optimal solution.
[0009] This utility model has a reasonable structural design, is convenient to produce, install and use, has good stability, good linkage effect, strong versatility and wide application range; it is suitable for use as a tensioning locking device for container energy storage cabinet doors and similar multi-locking cabinet doors, as well as for structural improvements of similar products.
