Description

Technical Field

[0001] The invention belongs to the technical field of power transmission and distribution, and in particular relates to a distribution box which is easy to open and close. Background Art

[0002] A distribution box is a device used to distribute electrical energy, control and protect circuits in power systems. It is usually installed inside buildings or outdoors. It can convert high-voltage or medium-voltage electrical energy into low-voltage electrical energy and distribute it to various electrical equipment. It is currently widely used in residences, shopping malls, factories, and public settings.

[0003] The distribution box includes a box body, a box door, and a lock structure. The lock structure usually includes a lock core and a lock plate arranged on the inner and outer sides of the box door. The lock plate can be rotated using a key that matches the lock core. After rotation, the lock plate engages with the inner side of the box body to lock the box door, or disengages from the box door to unlock the box door.

[0004] The above lock structure is relatively simple as a whole, and is therefore currently adopted by most distribution boxes. However, in actual use, the following defects exist: (1) When the box door is opened, if the lock plate is accidentally turned to the locked state and the operator directly closes the box door, the lock plate will be directly damaged; (2) Each time the box door is locked and unlocked, a key must be used, which is not convenient for use in scenarios where the box door needs to be opened and closed frequently, such as during regular maintenance and inspection. Summary of the invention

[0005] The existing distribution box, when the door is closed, when the lock plate is in a locked state, will directly cause damage to it, and the unlocking and locking of the door require the help of a key, which is not convenient for the door to be opened and closed quickly, and reduces the efficiency of the box maintenance and inspection. In order to solve the above problems, the following invention is proposed:

[0006] The lock plate is engaged with the locking cam and is adapted to engage with the locking cam when the door is opened and the locking cam is engaged with the locking cam.

[0007] Furthermore, a square hole for the core column to movably pass through is provided on the lock plate, a connecting hole is provided on the lock plate, and an axial hole is provided on the mounting seat. A connecting shaft is threadedly connected to the axial hole, and an end of the connecting shaft is movably inserted into the connecting hole to rotatably connect the lock plate and the mounting seat.

[0008] Furthermore, a cover plate and a fixing member are provided at the opening of the mounting groove, the first baffle plate is located between the cover plate and the fixing member, and the fixing member is threadedly connected to the core column to fix both the first baffle plate and the cover plate on the mounting seat.

[0009] Furthermore, a second baffle is provided between the fixing member and the cover plate to block the other side of the lock plate to prevent the lock head from moving toward the outside of the box door. A guide slope and a guide channel located inside the box body are provided on the side plate. The guide channel is connected to the guide slope. When the first baffle is not installed, the box door is pulled outward until the lock head contacts the guide slope, and then one end of the lock plate moves inward and finally passes over the side plate to open the box door.

[0010] Furthermore, an outer sleeve plate is provided around the cover plate and is attached to the outer side of the mounting seat; the first baffle plate and the second baffle plate both include a connecting arm and a baffle head, the connecting arm is provided between the fixing member and the cover plate, and the baffle head is in contact with the lock plate to prevent the end of the lock plate from moving.

[0011] Furthermore, a spring groove for inserting one end of the spring is provided in the installation groove; and the installation seat and the cover plate are both sleeved on the core column.

[0012] Furthermore, a mounting plate is also provided in the box body, and the mounting plate is fixedly connected to the back plate through a plurality of threaded members. The position of the mounting plate can be adjusted by screwing the threaded members in and out, which is relatively convenient.

[0013] The present invention proposes a distribution box that is easy to open and close, and its beneficial effect is that by adjusting whether the first baffle or the second baffle is installed, the door of the distribution box can be closed or opened in one direction without the help of a key, and during the closing process, the lock plate will not be damaged, so that the operator can quickly close or open the door during maintenance, which is more convenient.

[0026] like Figure 1-Figure 3 As shown, it is a distribution box that is easy to open and close proposed by the present invention, including a box body 1 and a box door 11, the box body 1 includes a back plate 13 and side plates 12 arranged on both sides of the back plate 13, the back plate 13 is connected to a mounting plate 17 through a plurality of screw members 18, and the position of the mounting plate 17 can be changed by adjusting the screw members 18, the box door 11 is movably mounted on one of the side plates 12, and a locking portion 16 is provided on the other side plate 12, and a lock seat 2 is also fixedly installed on the box door 11, the lock seat 2 is provided with a lock hole, and a lock core 21 is provided in the lock hole, and the end of the lock core 21 is drivingly connected to a lock plate 23, and a lock head 26 is provided on one side of the lock plate 23, by fitting a lock core 21 When the key is inserted into the keyhole, the lock cylinder 21 can be rotated, and the lock cylinder 21 rotates to drive the lock plate 23 to rotate together. When the door 11 is in the closed state, the lock plate 23 rotates, and the lock head 26 rotates into the inner side of the locking portion 16 or rotates out from the inner side of the locking portion 16 to lock or unlock the side plate 12, thereby achieving the purpose of locking and unlocking the door 11. For the convenience of subsequent explanation, the rotation state when the lock plate 23 is engaged with the locking portion 16 is called the locked state, and the rotation state when it is not engaged with the locking portion 16 is called the unlocked state. It should be noted that even when the door 11 is opened, the lock plate 23 can still be rotated to the locked state.

[0027] Implementation Case 1

[0028] The lock core 21 is also provided with a stem 22 extending toward the inner side of the door 11, and a through hole is provided at the end of the stem 22. A matching hole 36 matching the stem 22 is provided on the cover 4, and a hole matching the stem 22 is also provided on the mounting seat 3, so that the mounting seat 3 and the cover 4 are both sleeved on the stem 22. One side of the cover 4 blocks the opening of the mounting groove 31, and the other side is provided with a fixing member 42 threadedly connected to the through hole at the end of the stem 22. After the lock core 21 rotates, it drives the mounting base 3, the cover plate 4, and the fixing member 42 to rotate together; a mounting groove 31 is provided in the mounting base 3, and the lock plate 23 is elastically connected to the mounting groove 31 by a spring 32, and is rotatably connected to the arm plate on the mounting base 3, and a first baffle 5 is provided between the fixing member 42 and the cover plate 4, and the first baffle 5 includes a connecting arm 51 and a baffle head 52, wherein the connecting arm 51 is in contact with the fixing member 42 and the cover plate 4, and the baffle head 52 abuts against the side of the lock plate 23 close to the lock head 26.

[0029] After the fixing member 42 is fully tightened, the first baffle plate 5 and the cover plate 4 are both fixed on the mounting base 3. Since the stopper 52 of the first baffle plate 5 now abuts against the side of the lock plate 23 close to the lock head 26, the lock head 26 on the lock plate 23 can only move toward the outside of the box door 11, but cannot move toward the inside of the box door 11. When closing the door 11, depending on the rotation of the lock plate 23 on the door 11, there are two possibilities: (1) when the lock plate 23 is in the unlocked state, during the process of opening and closing the door 11, the lock plate 23 will not touch the side plate 12 of the box body 1, and the door 11 can be opened and closed normally; (2) when the lock plate 23 is mistakenly rotated to the locked state, during the process of closing the door 11, the lock head 26 of the lock plate 23 will touch the side plate 12 of the box body 1, and the lock plate 23 will elastically rotate toward the outside of the door 11. When the door 11 is completely closed, the lock plate 23 will break away from the contact with the side plate 12, enter and engage with the locking part 16 on the inner side of the side plate 12 to complete the locking of the door 11. The whole process will not cause damage to the lock plate 23. In this embodiment, after the door 11 is opened, the operator can directly rotate the lock plate 23 to the locked state and then remove the key, which will not affect the subsequent closing of the door 11 and reduces the possibility of losing the key.

[0030] When the box door 11 is pulled outward, the lock head 26 will conflict with the locking part 16, and the lock plate 23 is blocked by the first baffle 5 and cannot move toward the inside of the box door 11 to prevent the box door 11 from being directly pulled open. When the box door 11 really needs to be opened, it is still necessary to use the key to rotate the lock core 21. After the lock core 21 rotates, it drives the lock plate 23 to rotate, thereby releasing the engagement between the lock head 26 and the locking part 16.

[0031] Furthermore, a square hole 24 is provided on the lock plate 23 for the core column 22 to movably pass through, a connecting hole 25 is provided on the lock plate 23, and an axial hole 35 is provided on the mounting seat 3. A connecting shaft 33 is threadedly connected to the axial hole 35, and an end of the connecting shaft 33 is movably inserted into the connecting hole 25 to rotatably connect the lock plate 23 and the mounting seat 3. When the lock plate 23 rotates around the connecting shaft 33, the square hole 24 moves relative to the core column 22; in addition, a spring groove 34 is provided in the mounting groove 31 for inserting one end of a spring 32, and the spring 32 is sleeved on the outside of the core column 22; an outer sleeve plate 41 is provided on the periphery of the cover plate 4 to fit the outside of the mounting seat 3 to improve the stability of the connection between the cover plate 4 and the mounting seat 3.

[0032] Implementation Case 2

[0033] The distribution box proposed in Implementation Case 1 cannot be opened without a key after the box door 11 is closed. In actual use, in certain emergency scenarios, it may be necessary to quickly open the box door 11 without a key, such as when a power transmission and distribution system fails.

[0034] To solve the above problems, based on implementation case 1, in this embodiment, the first baffle 5 arranged between the fixing member 42 and the cover plate 4 is replaced with a second baffle 6, and the second baffle 6 also includes a connecting arm 51 and a stop head 52, and the connecting arm 51 is fitted and fixed between the fixing member 42 and the cover plate 4, and the stop head 52 is abutted against the other side of the lock plate 23 to prevent the lock plate 23 from moving toward the outside of the box door 11, and a guide slope 14 and a guide channel 15 are provided on the inner side of the locking portion 16 of the side plate 12, and the guide channel 15 is connected to the guide slope 14, and when the box door 11 is pulled outward, the lock head 26 conflicts with the guide slope 14, and the lock plate 23 is driven by the lock head 26 to elastically rotate toward the box body 1, and then the lock head 26 enters the guide channel 15 until it is separated from the side plate 12, thereby realizing the opening of the box door 11.

[0035] It should be particularly noted that the fixing member 42 may be loosened, and then the first baffle 5 may be rotated to serve as the second baffle 6. In this embodiment, the first baffle 5 and the second baffle 6 are distinguished for related description in subsequent embodiments.

[0036] Implementation Case 3

[0037] In some situations where the door 11 needs to be opened and closed frequently, such as when the box body 1 is regularly maintained and inspected, based on implementation case 2, the first baffle plate 5 and the second baffle plate 6 may not be installed, or after the fixing member 42 is loosened, the first baffle plate 5 and the second baffle plate 6 may be rotated to a position where the baffle head 52 no longer blocks the lock plate 23. At this time, the rotation of the lock plate 23 and the lock head 26 toward the inside and outside of the door 11 is not affected. After the lock plate 23 is rotated to the locked state, the operator can open or close the door 11 at will without the help of a key.

[0038] At this time, the box door 11 is not locked after being closed, and anyone can open the box door 11 at will. This embodiment is only suitable for temporary fixation of the box door 11, mainly to prevent the electronic equipment in the box body 1 from being exposed to the outside world for a long time and being damaged. When the distribution box is used normally, the technical solution in implementation case 1 needs to be adopted.

[0039] Based on the above implementation case, the first baffle 5 and the second baffle 6 can also be set at the same time, and the baffle heads 52 on the two baffles respectively abut against the two sides of the lock plate 23 to prevent the lock plate 23 from elastically rotating toward the inside and outside of the box door 11. At this time, the opening and closing of the box door 11 must be carried out with the help of a key, that is, this application is no different from a general distribution box.

[0040] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
