Description

Technical Field

[0001] The utility model relates to a connecting rod lock body, in particular to a connecting rod lock body, a cabinet door and an outdoor cabinet, belonging to the technical field of door locks. Background Art

[0002] Existing outdoor cabinet doors usually adopt a door lock solution with a hinge on one side and a connecting rod lock on the other side. The corresponding existing connecting rod lock locking point is usually only set on one side of the cabinet. With the development of outdoor cabinets, there are more and more double-door designs, the equipment to be installed is becoming more and more complicated, and the internal space is becoming more and more compact. Conventional connecting rod lock devices are difficult to meet the requirements of small space occupation, strong sealing and reliable installation at the same time. When the outdoor cabinet is designed with double doors, the conventional design is to install a connecting rod lock on each door, and each door is opened and closed separately. Each connecting rod lock takes up a large part of the space, so sometimes the width of the cabinet cannot meet the requirements of installing two locks at the same time.

[0003] The usual solution to the above problem is to install a linkage lock on one of the doors, and use sheet metal design on the other door so that the door with the lock installed can press the door without the lock installed when locked, so that both doors are locked. However, this solution has several defects. First, since the door without the lock is locked by pressing the other door, the waterproof sealing performance of this locking solution is greatly reduced compared to the linkage lock solution, and there is a certain risk of water leakage; second, since the two doors are locked by only one lock, and due to the special structure of the push rod lock, when the overall flatness of the door frame of the outdoor cabinet does not meet the requirements, the switch resistance of the door lock of the single door will be relatively large, and the lock on the lock rod and the lock seat are difficult to match together due to resistance. Utility Model Content

[0004] In order to solve the shortcomings of the above-mentioned technology, the utility model provides a connecting rod lock body, a cabinet door, and an outdoor cabinet. When the outdoor cabinet is designed as a double-door and the cabinet width space cannot meet the needs of installing a set of connecting rod locks on each door, a vertically arranged combined connecting rod lock body is designed and installed on the two doors respectively, and a reasonable door lock scheme is designed to achieve the closing and locking of the cabinet door.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a connecting rod lock body, including two sets of lock bodies symmetrically arranged up and down and used for double-door cabinets, each set of lock bodies includes a lock core, a lock rod, and a lock core matching part, the upper part and the lower part of the lock rod are respectively vertically provided with a lock core, and the lock core is matched and inserted in the lock core matching part and movably connected thereto;

[0006] One end of the lock rod is connected to the rotating shaft, and the rotating shaft is connected to the driving part. The lock rod is driven by the rotating shaft to make a linear motion. When the lock rod moves up and down, it drives the lock core to slide in or out of the lock core matching part.

[0007] Preferably, the lock core matching portion includes a base plate, and a locking plate and a positioning plate spaced apart on the base plate, and a channel for the locking rod to pass through is formed between the locking plate and the positioning plate.

[0008] Preferably, the locking plate and the positioning plate are symmetrically provided with downwardly opening slideways, and the lock cores are matched and inserted into the slideways.

[0009] Preferably, a plurality of positioning blocks are sleeved at intervals on the locking rod.

[0010] Preferably, the driving part includes a gear and a matching plate, wherein one side of the matching plate close to the gear has a rack meshing with the gear, and the center of the other side protrudes upward to form an insertion groove matching the rotating shaft.

[0011] Preferably, a limiting plate is matchedly sleeved outside the insertion slot, and a sliding groove is formed on the limiting plate for the insertion slot to slide.

[0012] A cabinet door is a double-opening door, comprising a first door leaf and another door leaf which is an inverted version of the first door leaf, and connecting rod lock bodies are installed on both door leaves.

[0013] Preferably, both door leaves are rotatably connected to the door frame, and when the cabinet door is in a closed state, the connecting rod lock bodies on the two door leaves are on the same vertical axis.

[0014] An outdoor cabinet comprises a cabinet body and a cabinet door, wherein the cabinet body and the cabinet door are connected via a hinge.

[0015] The utility model realizes that two sets of locks can be installed vertically by designing a special door sheet metal structure and door lock scheme, and provide a pressing force to each other to achieve a stable locking state. The simulation results show that this door lock scheme can effectively reduce the space occupied by the double door linkage lock, and at the same time has better anti-theft and sealing effects.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 3 , Figure 4 A connecting rod lock body shown in the figure comprises two sets of lock bodies which are symmetrically arranged up and down and are used for double-door cabinets, each set of lock bodies comprises a lock core 1, a lock rod 2, and a lock core matching portion 3, the upper and lower parts of the lock rod 2 are respectively vertically provided with a lock core 1, and the lock core 1 is matched and inserted into the lock core matching portion 3 and movably connected thereto;

[0026] Each set of lock bodies drives the lock core thereon to move through the lock rod, so that the lock core slides into or out of the lock core matching part, thereby realizing locking or opening of the door leaf.

[0027] In one embodiment, one end of the locking rod 2 is connected to the rotating shaft 41, and the rotating shaft 41 is connected to the driving part 4 for transmission. The locking rod 2 is driven by the rotating shaft 41 to make linear motion. When the locking rod moves up and down, it drives the lock core to slide in or out of the lock core matching part.

[0028] When the connecting rod lock body is in use, the lock core matching part needs to be installed on the door frame stop, and the locking rod is movably connected to the door leaf. The driving part installed on the door drives the rotating shaft to rotate. Since the rotating shaft and the locking rod are connected in transmission, the locking rod is driven to slide up and down by rotating the driving part, thereby achieving the locking effect of the lock core.

[0029] In one embodiment, Figure 5 As shown, the lock core matching part 3 includes a bottom plate 31, and a locking plate 32 and a positioning plate 33 arranged at intervals on the bottom plate 31, and a passage for the lock rod to pass through is formed between the locking plate 32 and the positioning plate 33. Preferably, a slideway 34 with an opening downward is symmetrically provided on the locking plate 32 and the positioning plate 33, and the lock core 1 is matched and inserted into the slideway 34.

[0030] When the locking rod is inserted into the channel formed by the locking plate and the positioning plate, the lock core on the locking rod is just inserted into the slide, and the door leaf is in a locked state; when the lock needs to be unlocked, the driving part needs to be rotated, and the driving part drives the locking rod to slide downward or upward through the rotating shaft, so that the lock core slides out of the slide (that is, disengages from the lock core matching part), thereby unlocking the door leaf.

[0031] Further, in order to ensure the linear sliding of the locking rod, a plurality of positioning blocks 6 are spaced apart on the locking rod 2. The positioning blocks are arranged at equal intervals and are located on the same vertical line to ensure the linear sliding of the locking rod.

[0032] In one embodiment, the driving part 4 includes a gear and a matching plate. The matching plate has a rack meshing with the gear on one side near the gear, and the center of the other side is upwardly protruded to form an insertion groove matching with the rotating shaft. By rotating the door handle connected to the gear, the door handle drives the gear to rotate, and the gear rotation drives the rack meshing with it to move up and down. The rack moves while driving the insertion groove, which is an integral structure with it, to move up and down, and further drives the rotating shaft to move up and down, thereby driving the lock rod to move up and down, and realizing the locking or unlocking of the lock cylinder.

[0033] Note: The specific structure of the driving part is existing technology and will not be described here. The driving parts on the market that can convert rotational motion into linear motion are within the protection scope of this design.

[0034] Furthermore, a limiting plate 42 is matched and sleeved outside the insertion slot, and a sliding groove for the insertion slot to slide is formed on the limiting plate 42. The sliding groove is provided on the limiting plate to limit the moving range of the insertion slot, thereby limiting the up and down movement of the locking rod, so that the locking rod can lock or unlock the door leaf.

[0035] like Figure 6 As shown, the door leaf is in a closed state. At this time, the lock core on the connecting rod lock body is stuck in the slideway of the lock core matching part, and the upper half of the left door leaf cannot rotate. At the same time, the flange of the upper half of the left door leaf is pressed on the fold extending from the upper half of the right door leaf, and the upper half of the right door leaf is also unable to rotate. Similarly, the lower halves of the two doors are in the same state, forming an interlocking.

[0036] Turn the handles of both doors at the same time, the lock rod of the upper part of the left door leaf moves down, the lock rod of the right door leaf moves up, and the lock core slides out of the lock core matching part. At this time, the upper part of the left door leaf can move, and at the same time, the upper part of the right door leaf can also move without being pressed by the upper part of the left door leaf. Similarly, the lower part of the two doors can also move, so both doors are unlocked as a whole.

[0037] A cabinet door, the cabinet door is a double door, such as Figure 1 As shown, it includes a first door leaf 5 and another door leaf (such as Figure 2As shown in the figure), connecting rod lock bodies are installed on both door leaves.

[0038] Furthermore, both door leaves are rotatably connected to the door frame, and when the cabinet door is in a closed state, the connecting rod lock bodies on the two door leaves are on the same vertical axis.

[0039] There are two situations for the driving part. The first situation is that the lock core is inserted into the lock core matching part, and the second situation is that the lock core is separated from the lock core matching part. When the driving parts on both door leaves are in the first situation, the two door leaves are in a closed state, and the lock cores of each door leaf are inserted into their respective lock core matching parts to form four locking points, so that the upper half of the first door leaf and the lower half of the other door leaf are in a locked state. Figure 6 The hem portion of the first door leaf is shown to press against the flange portion of the other door leaf, forming a pressing force, so that the upper half of the other door leaf is also in a locked state. Similarly, the lower half of the first door leaf is also locked according to this principle, thus achieving double interlocking, improving the locking effect, and strengthening the sealing of the outdoor cabinet door leaf.

[0040] When the rotating shafts on the two door leaves are rotated, the driving parts on the two doors change from the first state to the second state. When the rotating shafts rotate, the rotating shafts drive the locking rod to move, so that the lock core changes from a state of being inserted by the lock core matching part to a state of being disengaged from the lock core matching part. At this time, the two doors can be opened.

[0041] When only one of the two doors, such as the driving part on the first door leaf, changes from the state of the first situation to the state of the second situation, at this time, since the rotating shaft of the other door does not rotate, the lock core and the lock core matching part are still in an interlocked state, and at the same time, the hem part of the lower half of the other door is still pressed against the flange part of the first door leaf, and the pressing force provided makes it impossible for the first door leaf to rotate and open. Similarly, the other door cannot be rotated and opened due to the pressing of the first door leaf. Therefore, the door lock scheme has a high anti-theft effect, and the connecting rod lock body has the advantages of simple structure and easy use.

[0042] An outdoor cabinet comprises a cabinet body and a cabinet door, wherein the cabinet body and the cabinet door are connected via a hinge.

[0043] The purpose of the utility model is to provide a connecting rod lock body, which can achieve the interlocking effect of two doors by installing the connecting rod lock body on each door, thereby improving the waterproof sealing performance. At the same time, the locking rod can lock the door leaf through the sliding of the lock core, which has a high anti-theft effect.

[0044] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
