Description

Technical Field

[0001] The present invention relates to a door lock for a container energy storage cabinet, and is a multi-point locking mechanism for a container energy storage cabinet. Background Art

[0002] The existing container energy storage cabinet door is one of the high-sealing doors. High-sealing doors are mainly used in fields such as van cars, containers, and freight railways, and are transported through carriages with a hanging or integrated overall closed independent structure. Therefore, the transportation conditions, sanitation conditions, and the safety and integrity of goods, etc. have been significantly improved. Such high-sealing doors generally lock the cabinet door through a connecting rod. Among them, the connecting rod lock of the connecting rod needs to install locking accessories such as a guide member and a positioning member on the door panel, and multiple assembly steps are required to realize the locking action of the cabinet lock body. For example, the application number disclosed in the Chinese patent document is 20202318197.2, the authorization announcement date is October 15, 2021, and the utility model name is "An Energy Storage Container Cabinet Door"; however, the existing conventional container energy storage cabinet locks generally have problems: 1. Exposed on the outside, they are prone to rust and corrosion; 2. Occupy the outside space, which is not conducive to sea transportation. Summary of the Invention

[0003] To overcome the above deficiencies, the purpose of the present invention is to provide a multi-point locking mechanism for a container energy storage cabinet to the art, so as to solve the technical problems that components such as connecting rods of existing similar products are prone to rust and corrosion when exposed, and the outside space occupied is relatively large, which is relatively unfavorable for sea transportation. Its purpose is achieved through the following technical solutions.

[0004] A multi-point locking mechanism for a container energy storage cabinet, the mechanism comprising a cabinet body, a cabinet door, a lock body and a lock point link assembly. The lock point link assembly includes a link assembly and a lock point assembly. One side edge of the cabinet door is opened or closed through a hinge provided between the corresponding side door frame at the cabinet body. The lock point link group is placed in the sandwich layer between the cabinet door and a fixing plate at the rear of the cabinet door. The fixing plate is integrated with the cabinet door. The link assembly of the lock point link assembly is arranged in an X shape. The first connecting piece of the link assembly serves as a driving piece, and one end of the first connecting piece is hinged to one end of the lock body rack protruding from the lock body. When the handle of the lock body is reciprocally pulled after being unlocked through the lock core and drives the corresponding gear to rotate, the lock body rack drives the first connecting piece to move up and down, and drives the link assembly of the lock point link assembly to move up and down in linkage. The link assembly drives one end of the lock head piece of the lock point assembly of the lock point link assembly to unlock or lock the inner side of the door frame of the cabinet body. The lock head rod of the lock point assembly is limited and fixed to move up and down on the cabinet door or the fixing plate through a guiding piece or a positioning piece. The structural design key point is that the lock point assemblies of the lock point link assembly are respectively arranged in four side slots at the fixing plate on the inner side of the cabinet door in a four-lock-point setting with two on the upper and lower sides being symmetric. The other ends of the upper two side lock point assemblies are respectively hinged to one end of the first link symmetrically arranged on both sides of the link assembly through a linkage piece. The first links are respectively symmetrically arranged on both sides above the lock body. The other ends of the first links are respectively hinged to one side of the second link at the middle swing holes of the second connecting pieces on both sides below the lock body. The ends of the second link on one side of the second link are respectively hinged to one end of the second link. The other ends of the second links are respectively hinged to both sides of the other end of the first connecting piece below the lock body. The second links are symmetrically arranged in a triangle on both sides below the first connecting piece. The swing holes of the second connecting pieces are respectively fixedly arranged to swing on the cabinet door or the fixing plate. The other ends of the second connecting pieces are respectively hinged to one end of the third links on both sides below the lock body. The other ends of the third links are respectively hinged to the linkage pieces at the other ends of the lower two side lock point assemblies. The first links and the second links on both sides are respectively obliquely braced outwards. Thus, the main components such as the links of the mechanism are arranged in the sandwich layer between the cabinet door and the fixing plate, and only the end position of the lock head piece at the lock point assembly of the lock point link assembly protrudes from the notch at the side slot of the fixing plate.

[0005] The length of the first link 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. Thus, the position of the lock body of the mechanism is located at a position slightly lower than the middle of the cabinet door, and the operation of the lock body is relatively convenient.

[0006] The lock body is a surface-mounted handle lock. One end of the surface-mounted handle of the surface-mounted handle lock is connected to the surface-mounted ratchet sleeve through the surface-mounted handle seat. The surface-mounted handle, the surface-mounted handle seat, and the surface-mounted ratchet sleeve are integrated. The ratchet ring on the inner wall of the surface-mounted ratchet sleeve meshes with the outer diameter teeth of the surface-mounted ratchet. When the surface-mounted handle is reciprocally toggled, it drives the rotation of the reciprocating surface-mounted ratchet sleeve, and the surface-mounted ratchet sleeve drives the rotation of the surface-mounted ratchet inside and outside the surface-mounted lock case; one end of the surface-mounted square shaft at the center of the surface-mounted ratchet extends out of the surface-mounted housing seat at the bottom of the surface-mounted lock case and drives the rotation of the surface-mounted driving gear inside and outside the surface-mounted bottom plate below the surface-mounted lock case. The surface-mounted driving gear drives the synchronous rotation of the surface-mounted driven gear meshing inside the surface-mounted bottom plate. The surface-mounted driven gear drives the up and down movement of the surface-mounted rack that meshes with each other on one side inside the surface-mounted bottom plate, and one end of the surface-mounted rack extends out of the surface-mounted bottom plate; on one side of the surface-mounted ratchet inside and outside the surface-mounted lock case, there are symmetrically arranged surface-mounted stop blocks that are respectively abutted against the outer diameter teeth of the surface-mounted ratchet through surface-mounted springs. Between the surface-mounted stop blocks, there is a surface-mounted cam block that is driven to rotate by the surface-mounted toggle button to unlock the two side surface-mounted stop blocks. The surface-mounted ratchet sleeve is connected to the other end of the surface-mounted square shaft through a surface-mounted fastening screw. The surface-mounted toggle button is located inside the surface-mounted ratchet sleeve within the inner diameter of the toggle button hole of the surface-mounted handle seat. One end of the surface-mounted toggle button is connected to the surface-mounted cam block below through the surface-mounted lock shaft that penetrates the surface-mounted ratchet sleeve. The surface-mounted ratchet on the surface-mounted square shaft is limited within the surface-mounted square shaft hole of the surface-mounted housing seat; the link assembly arranged in an X shape can be replaced by the upper and lower rods on both sides, and the upper and lower rods on both sides are respectively connected to the surface-mounted racks on both sides of the driven gear up and down. The surface-mounted rack of the above surface-mounted handle lock is connected to the driving member of the X-shaped link at the container energy storage cabinet door. When the surface-mounted rack moves up and down, it drives the unlocking or locking of the lock point of the X-shaped link through the driving member moving up and down; or it is convenient for the use of the surface-mounted handle lock in similar products such as the upper and lower rod door locks.

[0007] One end of the surface-mounted handle seat is fixedly connected to the surface-mounted handle. The surface-mounted hinge ears protruding from the bottom of the other end of the surface-mounted handle seat are buckled and hinged with the surface-mounted column heads protruding from both outer diameter sides of the surface-mounted ratchet sleeve through the sleeve holes of the surface-mounted housing seat. There is a surface-mounted lock sleeve on the outer diameter of the externally threaded sleeve protruding from the bottom of the sleeve hole of the surface-mounted housing seat. The surface-mounted housing seat is fixedly arranged in the mounting hole of the door panel through the surface-mounted lock sleeve. At the same time, the surface-mounted square shaft is inserted into the square hole of the surface-mounted driving gear inside the surface-mounted bottom plate at the rear of the door panel. The surface-mounted driving gear, the surface-mounted driven gear, and the surface-mounted rack are installed inside the surface-mounted bottom plate through the surface-mounted bottom cover. The above is the specific connection method of the surface-mounted handle seat with the surface-mounted handle and the surface-mounted ratchet sleeve, and the specific installation method of the surface-mounted driving gear, the surface-mounted driven gear, and the surface-mounted rack installed inside the surface-mounted bottom plate.

[0008] The surface-mounted lock case is provided with a surface-mounted lock core. The rotating shaft at the bottom of the surface-mounted lock core is connected to one end of the surface-mounted lock bolt inside the surface-mounted lock case. The other end of the surface-mounted lock bolt abuts against and locks or disengages and unlocks the outer diameter of the surface-mounted ratchet sleeve inside and outside the surface-mounted lock case. The above structure facilitates the unlocking and locking of the surface-mounted handle, that is, the locking and opening of the surface-mounted handle are realized through the limitation of the surface-mounted ratchet sleeve.

[0009] The outer handle base is arranged in the notch at one side opening of the outer lock case. The above structure facilitates the overall assembly and the operation of the outer handle.

[0010] The lock body is a recessed panel lock. One end of the recessed handle of the recessed panel lock is connected to the recessed ratchet sleeve through the recessed handle base. The recessed handle, the recessed handle base and the recessed ratchet sleeve are integrated and arranged in the handle groove on one side of the recessed panel. The notch of the handle groove of the recessed panel is provided with an outward-turned skirt. The ratchet tooth ring on the inner wall of the recessed ratchet sleeve meshes with the outer diameter tooth opening of the recessed ratchet. When the recessed handle is reciprocally pulled, it drives the reciprocating recessed ratchet sleeve to rotate, and the recessed ratchet sleeve drives the recessed ratchet in the handle groove of the recessed panel to rotate; One end of the recessed square shaft at the center of the recessed ratchet extends out of the bottom of the recessed panel and drives the recessed gear in the bottom case below the recessed panel to rotate.

The bottom case is fixedly arranged at the bottom of the recessed panel; On both sides of the recessed ratchet in the recessed panel, there are symmetrically arranged recessed stop blocks that are respectively abutted against the outer diameter tooth opening of the recessed ratchet through the recessed springs. Between the recessed stop blocks, there is a recessed cam block that is driven to rotate by the recessed toggle button to unlock the two side recessed stop blocks. The recessed toggle button is located in the recessed ratchet sleeve inside the toggle button hole diameter of the recessed handle base. One end of the recessed toggle button is connected to the lower recessed cam block through the recessed lock shaft penetrating the recessed ratchet sleeve. The other end of the recessed square shaft is connected to the recessed ratchet sleeve through the recessed first screw. The recessed ratchet is limited in the recessed square shaft hole of the recessed panel and is provided with a recessed gasket. The recessed panel is fixedly arranged in the mounting hole of the door panel; The connecting rod assembly arranged in an X shape can be replaced by the upper and lower door tie rods on both sides. The upper and lower door tie rods on both sides are respectively connected to the upper and lower recessed racks on both sides of the recessed gear. The recessed rack of the above recessed panel lock is connected to the driving member of the X-shaped connecting rod at the container energy storage cabinet door. When the recessed rack moves up and down, it drives the lock point of the X-shaped connecting rod to unlock or lock through the driving member moving up and down; Or it facilitates the use of the recessed panel lock in similar products such as the upper and lower door tie rod door locks.

[0011] One end of the recessed handle base is fixedly connected to the recessed handle. The hinge ears protruding from both sides of the bottom of the other end of the recessed handle base are buckled and hinged with the recessed pin shafts penetrating through both sides of the outer diameter of the recessed ratchet sleeve. The recessed pin shaft is located above the recessed first screw in the recessed ratchet sleeve. The above is the specific connection method of the recessed handle base with the recessed handle and the recessed ratchet sleeve.
