Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cabinets, and more specifically, to a cabinet door lock structure. In addition, the utility model also relates to a cabinet door including the above cabinet door lock structure. Background Art
[0002] Energy storage cabinets are generally placed outdoors, and their protection level needs to reach IP55. The cabinet doors are mostly sealed by the compression of rubber strips, and the compression of the rubber strips is achieved by the rollers of the cabinet door lock rod entering the lock catch of the cabinet body.
[0003] In the prior art, considering the aesthetic requirements, the cabinet door lock piece is not arranged on the outer edge of the cabinet door, but the cabinet door lock piece is moved inward, so that there is a certain horizontal distance between the cabinet door lock piece and the lock rod, and a connecting rod needs to be set to realize the linkage between the two. However, the connecting rod has a lever effect, which not only easily amplifies the movement gap of the internal parts of the door lock, but also makes the lock rod affected by torque. Moreover, both the connecting rod and the lock rod are slender rods and are prone to bending deformation. After the lock rod is deformed, it cannot push the lock rod to the full position, so that the roller cannot fully enter the lock catch, resulting in the cabinet door not being tightly closed and leaking water.
[0004] In summary, how to ensure the locking effect of the cabinet door when the door lock is offset inward is an urgent problem to be solved by those skilled in the art at present. Content of the Utility Model
[0005] In view of this, the purpose of the utility model is to provide a cabinet door lock structure, which uses fluid pressure for transmission, avoids the problems of torsion and bending deformation of the lock rod caused by mechanical transmission, and improves the locking effect and service life of the cabinet door lock structure.

[0018] A cabinet door includes the cabinet door lock structure described in any one of the above.
[0019] The cabinet door lock structure provided by the present utility model utilizes the movement of the cabinet door lock piece to drive the shortening or elongation of the piston rod of the first actuating element, so that the pressure in the first actuating element increases or decreases. Under the drive of the pressure gradient, the fluid medium flows between the first actuating element and the second actuating element, thereby making the pressure in the second actuating element increase or decrease, and finally driving the lock rod to lock or unlock.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0029] The core of the present utility model is to provide a cabinet door lock structure, which uses fluid pressure for transmission, avoiding the problems of torsion and bending deformation of the lock rod caused by mechanical transmission, and improving the locking effect and service life of the cabinet door lock structure.
[0030] In addition, the present utility model also provides a cabinet door including the above cabinet door lock structure.
[0031] The cabinet door lock structure provided by the present utility model includes a cabinet door lock piece 1, a lock rod 6, a first actuator 3 and a second actuator 5 arranged vertically. The first actuator 3 is connected to the second actuator 5 through a pipeline 4, so that the fluid medium flows between the first actuator 3 and the second actuator 5 under the drive of pressure;
[0032] The piston rod of the first actuator 3 is connected to the cabinet door lock piece 1 through a driving plate, and the connection end of the piston rod of the second actuator 5 is connected to the lock rod 6. When the cabinet door lock piece 1 drives the piston rod of the first actuator 3 to compress the fluid medium, the fluid medium flows from the first actuator 3 to the second actuator 5, causing the piston rod of the second actuator 5 to extend and drive the lock rod 6 to lock.
[0033] Please refer to Figure 1 , the cabinet door lock piece 1 is arranged inside the cabinet door 10, the lock rod 6 is arranged on the outer edge of the cabinet door 10, and the roller at the free end of the lock rod 6 can cooperate with the lock catch 7 of the cabinet body 20 to lock; in order to facilitate the layout of the pipeline 4, generally, the first actuator 3 and the second actuator 5 are arranged between the cabinet door lock piece 1 and the lock rod 6, and the first actuator 3 is relatively close to the cabinet door lock piece 1, and the second actuator 5 is relatively close to the lock rod 6.
[0034] The first actuator 3 is connected to the second actuator 5 through the pipeline 4, that is to say, the medium outlet of the first actuator 3 is connected to the medium inlet of the second actuator 5, and the medium inlet of the first actuator 3 is connected to the medium outlet of the second actuator 5.
[0035] The number of pipelines 4 is determined according to the number of medium inlets and outlets of the first and second actuators in actual production. For example, when both the first actuator 3 and the second actuator 4 are provided with one medium inlet and one medium outlet, there are two pipelines 4 between the first actuator 3 and the corresponding second actuator 4 connected, as Figure 1 shown.
[0036] The distribution of the pipeline 4 is related to the structures and installation positions of the first and second actuators. Among them, the specific structures of the first and second actuators determine the positions of the medium inlets and outlets on the actuators, and the installation positions of the first and second actuators determine the positions of the medium inlets and outlets relative to the cabinet door 10, thereby determining the specific positions of both ends of the pipeline 4.
[0037] The specific type, model, size, etc. of the pipeline 4 need to be determined with reference to the prior art according to factors such as the type of fluid medium in actual production and the sizes of the first and second actuators, and will not be elaborated here.
[0038] To avoid leakage of the medium at the pipeline connection, it is preferably set that both ends of the pipeline 4 are threadedly connected to the first actuator 3 and the second actuator 5 respectively. Connecting the pipeline 4 and the actuators on both sides by means of threaded connection, the connection structure is simple, convenient for assembly, and the connection structure is stable and reliable, and it is not easy to leak.
[0039] To facilitate the processing and manufacture of the pipeline 4, it is preferably set that the structures and sizes of the connection ends at both ends of the pipeline 4 are the same, that is, the models and sizes of the first actuator 3 are the same as those of the second actuator 5, so that the structures and sizes of the medium inlets and outlets of both the first actuator 3 and the second actuator 5 are the same.
[0040] Preferably, to facilitate the layout of the pipeline 4, the first actuator 3 can be set parallel to the second actuator 5, and the installation height of the first actuator 3 is the same as that of the second actuator 5. At this time, the pipeline 4 is horizontally arranged, which can not only shorten the length of the pipeline 4, but also facilitate the assembly of the pipeline 4.
[0041] The piston rod of the first actuator 3 is connected to the cabinet lock piece 1 through a driving plate. The cabinet lock piece 1 can drive the piston rod of the first actuator 3 to move through the driving plate, and change the pressure in the first actuator 3 through the movement of the piston rod, drive the fluid medium to move under the action of the pressure gradient, and then change the pressure in the second actuator 5 to adjust the position of the piston rod of the second actuator 5.
[0042] The connection end of the piston rod of the second actuator 5 is connected to the lock rod 6. When the piston rod of the second actuator 5 extends, the piston rod pushes the lock rod 6 to move towards the lock catch 7, and pushes the roller of the lock rod 6 into the lock catch 7 until the lock rod 6 is locked with the lock catch 7; conversely, when the piston rod of the second actuator 5 shortens, the piston rod pushes the lock rod 6 to move away from the lock catch 7, driving the roller of the lock rod 6 to disengage from the lock catch 7, and unlocking the lock rod 6 from the lock catch 7.
[0043] Since the connection end of the second actuator 5 is directly connected to the lock rod 6, and the second actuator 5 is arranged vertically, the lock rod 6 is only subjected to the pulling force or pushing force in the vertical direction and will not be affected by torque, effectively avoiding the bending deformation of the lock rod 6.
[0044] Both the first actuator 3 and the second actuator 5 do work through a fluid medium, and both can be set as a pneumatic cylinder or a hydraulic cylinder; the specific types and models of the first actuator 3 and the second actuator 5 are not limited, as long as the types of the fluid medium in the first actuator 3 and the second actuator 5 are the same.
[0045] Considering that hydraulic cylinders are more prone to leakage problems than pneumatic cylinders, when both the first actuator 3 and the second actuator 5 are set as hydraulic cylinders, it is preferred to be provided with a leakage sensor on the pipeline 4 for detecting whether the hydraulic cylinder leaks. The specific type, model, etc. of the leakage sensor are determined according to the actual production needs and will not be elaborated here.
[0046] In this embodiment, the movement of the lock rod 6 is driven by using fluid pressure. Compared with the existing mechanical transmission, the influence of torque on the lock rod 6 is avoided, the lock rod 6 can be effectively prevented from deflecting and deforming, the service life of the lock rod 6 and the cabinet door lock structure is prolonged, and the stability and locking effect of the cabinet door lock structure are ensured.
[0047] Preferably, in order to make the force on the lock rod 6 more stable, it can be set that a connecting plate 6a is provided at the connecting end of the lock rod 6. The connecting plate 6a is arranged perpendicular to the lock rod body of the lock rod 6, and the center of the connecting plate 6a is located on the axis of the piston rod of the second actuator 5.
[0048] On the basis of the above embodiment, in order to facilitate the fixation of the first actuator 3 and the second actuator 5, it can be set that both the first actuator 3 and the second actuator 5 are arranged on the mounting seat 8. The mounting seat 8 is of an L-shaped structure. One end of the mounting seat 8 is connected to the inner side surface of the cabinet door 10, and the other end of the mounting seat 8 is connected to the first actuator 3 or the second actuator 5.
[0049] Considering that the horizontal distance L from the cabinet door lock piece 1 to the lock rod 6 is not large, usually L ≤ 10 cm. Therefore, the sizes of both the first actuator 3 and the second actuator 5 are relatively small and the mass is relatively light. The mounting seat 8 can be connected to the cabinet door 10 either by an adhesive method or by common fasteners such as fastening screws 9 and connecting pins.
[0050] It should be noted that when the mounting seat 8 is bolt-connected or pin-connected to the cabinet door 10, in order to prevent the fastener from abutting against the surface of the first actuator 3 or the surface of the second actuator 5 and affecting the appearance and outer wall strength of either the first actuator 3 or the second actuator 5, there is usually a gap between the fastener and the surface of the first actuator 3 or the surface of the second actuator 5.
[0051] The connection between the mounting seat 8 and the first actuating element 3 or the second actuating element 5 is usually set as a bolt connection or a pin connection. Not only is the connection structure simple, facilitating assembly and maintenance, but also the connection strength is high, which can ensure the mounting stability of the first actuating element 3 or the second actuating element 5.
[0052] For example, please refer to Figure 1 , fastening screws 9 are provided at the four corners of the first actuating element 3 and the four corners of the second actuating element 5. Both the first actuating element 3 and the second actuating element 5 are connected to the mounting seat 8 through the fastening screws 9. The fastening screws 9 are provided at the four corners of the actuating element, which not only avoids interference between the fastening screws 9 and the piston rod but also enhances the connection stability and reliability of the actuating element.
[0053] In this embodiment, the mounting seat 8 is used to fix the first actuating element 3 and the second actuating element 5 to the inner surface of the cabinet door 10, which has stronger mounting stability compared with structures such as clamps.
[0054] Considering that there are usually two cabinet door lock pieces 1 in actual production, the corresponding lock rods 6 are also two, and the moving directions of the two cabinet door lock pieces 1 are opposite, and the moving directions of the two lock rods 6 are also opposite.
[0055] In a specific embodiment, the cabinet door lock piece 1 includes an upper lock piece 11 and a lower lock piece 12. The upper lock piece 11 is connected to the first actuating element A 31 through an upper driving plate 21, and the piston rod of the first actuating element A 31 is arranged upward. The lower lock piece 12 is connected to the first actuating element B 32 through a lower driving plate 22, and the piston rod of the first actuating element B 32 is arranged downward.
[0056] The upper driving plate 21 and the lower driving plate 22 can be collectively referred to as the driving plate. It should be noted that in order to avoid interference between the two driving plates during movement, it is preferably set that the upper driving plate 21 is connected to the outer side surface of the upper lock piece 11 relatively far from the lock rod 6, and the lower driving plate 22 is connected to the inner side surface of the lower lock piece 12 relatively close to the lock rod 6.
[0057] The structure, shape and size of the upper driving plate 21 are determined according to the size of the first actuating element A 31 and the relative position relationship between the first actuating element A 31 and the upper lock piece 11 in actual production; the structure, shape and size of the lower driving plate 22 are determined according to the size of the first actuating element B 32 and the relative position relationship between the first actuating element B 32 and the lower lock piece 12 in actual production.
[0058] Preferably, it can be set that both the first actuating element A 31 and the first actuating element B 32 are vertically arranged, and the upper driving plate 21 and the lower driving plate 22 are set as L-shaped driving plates, which have a simple structure and are convenient for manufacturing and assembly.
[0059] When the size of the L-shaped drive plate is relatively large, a reinforcing plate can also be provided between the horizontal plate and the vertical plate of the L-shaped drive plate to increase the structural strength of the L-shaped drive plate.
[0060] When locking the cabinet door 10, the door lock handle drives the upper locking piece 11 to move downward and the lower locking piece 12 to move upward, driving the piston rod of the first actuator A 31 to move downward and the piston rod of the first actuator B 32 to move upward, so that the pressure inside the two first actuators 3 increases, and the fluid medium flows from the first actuator 3 to the second actuator 5, causing the pressure inside the second actuator 5 to increase, thereby pushing the piston rod of the second actuator 5 to move outward, that is, the piston rod of the second actuator A 51 moves upward and the piston rod of the second actuator B 52 moves downward, and further driving the upper locking rod 61 to move upward and the lower locking rod 62 to move downward, pushing the rollers of the two locking rods 6 into the corresponding locking sockets 7, realizing the firm locking of the cabinet door 10.
[0061] When opening the cabinet door 10, the door lock handle drives the upper locking piece 11 to move upward and the lower locking piece 12 to move upward, driving the piston rod of the first actuator A 31 to move upward and the piston rod of the first actuator B 32 to move downward, so that the pressure inside the two first actuators 3 decreases, and the fluid medium flows from the second actuator 5 to the first actuator 3, causing the pressure inside the second actuator 5 to decrease, thereby pushing the piston rod of the second actuator 5 to move inward, that is, the piston rod of the second actuator A 51 moves downward and the piston rod of the second actuator B 52 moves upward, and further driving the upper locking rod 61 to move downward and the lower locking rod 62 to move upward, driving the rollers of the two locking rods 6 to leave the locking socket 7 of the cabinet body 20, realizing the opening of the cabinet door 10.
[0062] In addition to the above cabinet door lock structure, the present utility model also provides a cabinet door 10 including the cabinet door lock structure disclosed in the above embodiments. For the structures of other parts of the cabinet door 10, reference can be made to the prior art and will not be elaborated herein.
[0063] It should be noted that the first and second in the first actuator 3 and the second actuator 5, the first actuator A 31 and the second actuator A 51, and the first actuator B 32 and the second actuator B 52 mentioned in this application document are only used to distinguish different positions and do not contain any limitation on the sequence.
[0064] In this specification, each embodiment is described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same and similar parts among the embodiments, reference can be made to each other.
[0065] The above has introduced in detail the cabinet door and the cabinet door lock structure provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
