[0032] Indicative diagram of distribution cabinet door lock structure, for reference. Figures 2 to 7 According to any preferred embodiment of the present utility model, a power distribution cabinet door lock structure, such as... Figure 2 As shown, the door 10 is mounted on the cabinet 20 and the cabinet 20 is rotatably mounted on the door body 10. The top and bottom of the cabinet 20 have several first insertion holes 201. The door lock structure of the power distribution cabinet includes two insertion rods 30 facing opposite directions, a triggering component 40 and two guide blocks 50.
[0033] Specifically, in any embodiment of this utility model, such as Figure 3 and Figure 4As shown, two insertion rods 30 are movably arranged on the door body 10; in addition, the triggering assembly 40 comprises a linkage 401 and a holding member 402, the linkage 401 is movably arranged on the door body 10 and connected with the holding member 402, the linkage 401 is simultaneously connected with two insertion rods 30, when the linkage 401 acts, two insertion rods 30 move towards each other and are separated from the first insertion hole 201 or two insertion rods 30 move away from each other and are inserted into the first insertion hole 201; two guide blocks 50 are arranged on one side of the door body 10 where the insertion rods 30 are arranged, and are located at the top and bottom of the door body 10, the guide blocks 50 correspond to the insertion rods 30 one by one, each guide block 50 has a guide hole 501, and each insertion rod 30 passes through the guide hole 501 on the corresponding guide block 50 and extends into or out of the first insertion hole 201.
[0034] It should be noted that, in the normal state, two insertion rods 30 are inserted into the corresponding first insertion hole 201, and the guide hole 501 provides a guiding effect for the insertion rod 30, when the electrician needs to open the door body 10 for maintenance, the linkage 401 is actuated to realize that two insertion rods 30 are simultaneously separated from the corresponding first insertion hole 201, at this time, the door body 10 and the cabinet 20 are no longer limited by the insertion rod 30, and can be opened. The present application realizes that the limiting structure between the door body 10 and the cabinet 20 is upgraded from one insertion rod 30 in the prior art to two insertion rods 30, which improves the difficulty of forcibly opening the door body 10 by external force, and when one insertion rod 30 is separated from the first insertion hole 201 due to failure, since the other insertion rod 30 is still normally arranged in the first insertion hole 201, the door body 10 is still in a closed state, it can be seen that, compared with the prior art, the present application has the advantages of providing double limiting and higher safety.
[0035] Specifically, in order to realize the movement of two insertion rods 30 when the linkage 401 acts, in the first embodiment of the present application, as shown in Figure 3 and Figure 4As shown in the figure, one side of the linkage 401 is fixedly connected with the handle 402, and the fixed connection mode is preferably welding. The handle 402 is rotatably installed on the door body 10. The other side of the linkage 401 is rotatably connected with the one end of the two insertion rods 30 facing each other. When the handle 402 rotates, the linkage 401 rotates with it, and drives the two insertion rods 30 to move towards or away from each other. In addition, in the first embodiment, the center axes of the two guide holes 501 are both obliquely arranged, that is, the two guide holes 501 are both inclined holes, and the included angle between the center axes of the two guide holes 501 is obtuse. The diameter of the guide hole 501 is larger than the rod diameter of the insertion rod 30, and when the insertion rod 30 is vertically arranged, the hole of the guide hole 501 does not interfere with the movement of the insertion rod 30.
[0036] It should be noted that in the first embodiment, when the two insertion rods 30 are collinear, the two insertion rods 30 are inserted into the corresponding first insertion hole 201. When the electrical personnel wants to open the door body 10, the electrical personnel only needs to rotate the end of the handle 402 away from the linkage 401. Since the linkage 401 is fixedly connected with the handle 402, the linkage 401 rotates along the anticlockwise direction in the figure by a predetermined angle, and drives the two insertion rods 30 to move upward by a predetermined distance in an inclined direction and out of the corresponding first insertion hole 201, thereby realizing the opening of the door body 10. When the handle 402 is rotated in the opposite direction, the linkage 401 drives the two insertion rods 30 to reinsert into the first insertion hole 201. Figure 3 It should be noted that in the first embodiment, since the insertion rod 30 is in an inclined state during movement, the diameter of the first insertion hole 201 is larger than the rod diameter of the insertion rod 30, and when the insertion rod 30 slightly inclines and abuts along the hole of the first insertion hole 201, that is, the insertion rod 30 is in the range of 89°-91°, the insertion rod 30 is also inserted into the first insertion hole 201.
[0037] Further, in the first embodiment, in order to avoid that the electrical personnel rotates the handle 402 by too much angle, as shown in the figures, Figure 3 and Figure 4 As shown in the figure, the linkage 401 also has an extension end 4011, and the linkage 401 is in the shape of a "T". The door body 10 has a protruding part 101. When the handle 402 is rotated by a predetermined angle, the extension end 4011 abuts against or separates from the protruding part 101.
[0038] It should be noted that when the extension end 4011 abuts against the protruding part 101, the handle 402 is rotated to the maximum angle, at which time the two insertion rods 30 are both out of the first insertion hole 201, and at this time the door body 10 can be opened.
[0039] Further, to avoid non-professionals rotating the holding piece 402 by themselves, as shown in the drawings, one end of the holding piece 402 away from the linkage 401 is rotatably installed with a swing ring 4021, the swing ring 4021 has a second insertion hole 40211, one side of the door body 10 away from the insertion rod 30 has a lock ring 102, when the swing ring 4021 rotates by a predetermined angle, the swing ring 4021 penetrates through the lock ring 102. Figure 5
[0040] It should be noted that when the swing ring 4021 penetrates through the lock ring 102, an electrician passes a lock through the second insertion hole 40211 and the ring hole of the lock ring 102, at this time, the swing ring 4021 cannot be separated from the lock ring 102, and the holding piece 402 cannot be rotated, thereby avoiding non-professionals opening the door body 10 for various purposes.
[0041] Figure 6 And Figure 7 As shown in the drawings, a second embodiment of the utility model is shown, in the second embodiment, the holding piece 402 is fixedly installed on the door body 10, the holding piece 402 has a sliding cavity 4021, the linkage 401 is slidingly arranged in the sliding cavity 4021, the touch assembly 40 further includes a pressing piece 403, the pressing piece 403 is liftingly arranged on the holding piece 402, one end of the linkage 401 away from the holding piece 402 has a first inclined surface 4012, the pressing piece 403 has a second inclined surface 4031, the first inclined surface 4012 is attached to the second inclined surface 4031, one end of the linkage 401 away from the pressing piece 403 is connected with two insertion rods 30 at the same time, when the pressing piece 403 makes lifting movement, the linkage 401 makes forward and backward movement and drives two insertion rods 30 to make opposite or opposite movement.
[0042] It should be noted that in the second embodiment, when the electrician needs to open the door body 10, only needs to press the pressing piece 403, the linkage 401 slides along the sliding cavity 4021 in the direction away from the insertion rod 30, and drives two insertion rods 30 connected with the linkage 401 to make opposite movement and out of the corresponding first insertion hole 201.
[0043] Further, in the second embodiment, to realize the connection of the linkage 401 and two insertion rods 30, as shown in the drawings, the touch assembly 40 further includes two rope bodies 404, the rope body 404 corresponds to the insertion rod 30 one by one, both ends of each rope body 404 are respectively bound with the linkage 401 and the corresponding insertion rod 30. Figure 7 Further, in the second embodiment, to realize the connection of the linkage 401 and two insertion rods 30, as shown in the drawings, the touch assembly 40 further includes two rope bodies 404, the rope body 404 corresponds to the insertion rod 30 one by one, both ends of each rope body 404 are respectively bound with the linkage 401 and the corresponding insertion rod 30.
[0044] It should be noted that the material of the rope 404 is preferably a non-elastic or weakly elastic nylon rope.
[0045] Furthermore, in the second embodiment, to ensure that when the electrician releases the pressing member 403, the linkage member 401 resets, the two insert rods 30 move in opposite directions, as follows: Figure 6 As shown, the actuation component 40 also includes two springs 405, each corresponding to one of the insertion rods 30. The two ends of each spring 405 are fixedly connected to the insertion rod 30 and the guide block 50, respectively. The fixed connection method includes, but is not limited to, welding.
[0046] It should be noted that when the two insertion rods 30 move toward each other, both springs 405 are in a stretched state. When the electrician releases the pressing member 403, the two insertion rods 30 are reset under the elastic force of the springs 405, and the linkage member 401 is reset through the rope 404. It should also be added that in the second embodiment, the diameter of the guide hole 501 is equal to the diameter of the insertion rod 30.
[0047] Furthermore, in the second embodiment, to prevent untrained personnel from opening the door 10, such as... Figure 7 As shown, the actuating component 40 further includes a sealing member 406 and an abutting rod 407. The sealing member 406 closes the end of the sliding cavity 4021 away from the insertion rod 30 and is fixedly connected to the gripping member 402 by welding. One end of the sealing member 406 has a first locking hole 4061, and the abutting rod 407 has a second locking hole 4071. When the first locking hole 4061 and the second locking hole 4071 are aligned, the abutting rod 407 abuts against the end of the linkage member 401 away from the insertion rod 30.
[0048] It should be noted that, under normal circumstances, the first lock hole 4061 and the second lock hole 4071 are directly opposite each other and are locked by a lock through the first lock hole 4061 and the second lock hole 4071. Since the sealing member 406 is welded to the grip member 402, it is difficult to pull the abutment rod 407. At this time, since the abutment rod 407 abuts against the linkage member 401, the pressing member 403 cannot be pressed, thus preventing non-professionals from opening the door 10. When electrical personnel need to open the door 10, they first open the lock and pull out the abutment rod 407, and then press the pressing member 403 to open the door 10.
[0049] In summary, the power distribution cabinet door lock structure described in the embodiments of this application is explained, which provides advantages such as dual limiting and higher security for the power distribution cabinet door lock structure.
[0050] It is worth mentioning that, in the embodiment of the application, the power distribution cabinet door lock structure is simple in structure, does not involve complex manufacturing process and expensive materials, and has high economy. At the same time, for the manufacturer, the power distribution cabinet door lock structure provided by the application is easy to produce and low in cost, which is more conducive to controlling the production cost, and is further conducive to product promotion and use.
