Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically to a distribution box door structure with self-adjusting closing direction function. Background Technology

[0002] As a core device in power distribution, the distribution box plays a crucial role in modern life. Like a "transfer station" in the power system, it rationally distributes electrical energy from the upstream power source to various power branches. From residential communities to commercial buildings, from factory workshops to transportation hubs, distribution boxes are ubiquitous. They not only centrally control the on / off state of circuits but also possess overload and short-circuit protection functions, ensuring the safe and stable operation of electrical equipment. With the development of smart grid technology, today's distribution boxes are also upgrading towards intelligence and miniaturization, further improving the efficiency and reliability of power management.

[0003] Currently, common distribution box doors typically only open in one direction, such as from left to right or from bottom to top, limiting their usability. When the distribution box is installed in a confined space or is obstructed by obstacles, a single opening direction can prevent the door from opening properly, affecting maintenance and repair. Furthermore, the single-direction opening method is difficult to adapt to diverse operational needs in different installation environments. Therefore, we propose a distribution box door structure with a self-adjusting closing direction function. Utility Model Content

[0004] The purpose of this invention is to provide a distribution box door structure with self-adjusting closing direction function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A distribution box door structure with self-adjusting closing direction function includes a distribution box body, a door at the front end of the distribution box body, and a four-way opening mechanism installed on the inner wall of the door. The four-way opening mechanism includes a pair of longitudinal opening components respectively located at the inner wall edges of the top and bottom sides of the door, a pair of transverse opening components respectively located at the inner wall edges of the left and right sides of the door, and four locking knobs rotatably connected to the outside of the door. The longitudinal opening components are used to control the longitudinal opening and closing of the door, and the transverse opening components are used to control the transverse opening and closing of the door.

[0007] The distribution box has sockets at the two outer corners of the inner walls of all four sides.

[0008] The longitudinal door opening assembly includes a lever plate that is slidably connected to the door, two connecting rods that are symmetrically hinged to the bottom of the lever plate, a movable pin that is hinged to the end of the connecting rod, and a guide sleeve that is sleeved on the outside of the movable pin and slidably connected to the movable pin. The guide sleeve is fixedly connected to the door. When the movable pin extends outward from the guide sleeve, it can be inserted into the corresponding insertion hole. The top of the lever plate is provided with a lever, and the end of the lever penetrates the door.

[0009] The structure of the horizontal door opening assembly is the same as that of the vertical door opening assembly;

[0010] The positions of the locking knobs correspond to the positions of the longitudinal door opening components and the transverse door opening components, respectively. The bottom of the locking knob is provided with a hanging plate with a hanging groove. When the locking knob is rotated to hook the hanging plate onto the corresponding lever, the longitudinal door opening component or transverse door opening component corresponding to the lever is locked by the hanging plate.

[0011] Preferably, the longitudinal opening assembly is adapted to the lateral length of the cabinet door, and the lateral opening assembly is adapted to the longitudinal height of the cabinet door.

[0012] In this setup, the longitudinal and lateral door opening components are adapted to the lateral length and longitudinal height of the door respectively, ensuring that each component can fully cover the edge of the door, providing stable and effective support for opening and closing in different directions, and ensuring smooth hinge operation.

[0013] Preferably, the inner wall of the door is provided with four limiting blocks corresponding to the positions of the four-way opening mechanism and the longitudinal opening assembly, respectively. The lever plate is provided with a waist-shaped groove, through which the limiting blocks pass. The cross-section of the limiting block is T-shaped, and the protruding T-shaped edge of the limiting block restricts the lever plate between the outer edge of the limiting block and the inner wall of the door.

[0014] In this configuration, the T-shaped limit block works in conjunction with the waist-shaped groove to precisely limit the movement trajectory of the lever, preventing it from shifting or detaching during sliding, thus ensuring the stability and reliability of the door opening assembly.

[0015] Preferably, the door has four movable slots for the movement of four levers. By moving the levers in the corresponding movable slots, the levers can drive the levers on the corresponding longitudinal door opening components or transverse door opening components to move.

[0016] In this setting, the movable groove provides a clear movement path for the lever, making the toggle operation more precise, and at the same time, it allows users to drive the lever to the dial to flexibly switch the opening and closing direction of the cabinet door.

[0017] Preferably, the bottom end of the lever is provided with a base plate, and the beginning ends of the two connecting rods are respectively hinged to the beginning and end ends of the base plate;

[0018] In this configuration, the base plate provides a stable hinge point for the connecting rod, enhancing the integrity of the transmission structure of the lever plate, connecting rod, and movable pin, ensuring smooth power transmission and preventing component loosening.

[0019] Preferably, a stop plate is provided on the outer surface of the movable pin head end, and a spring is sleeved on the outer side of the movable pin between the stop plate and the guide sleeve, and the spring is in a pre-tightened state;

[0020] In this configuration, the preload spring keeps the movable pin tightly connected after it is inserted into the socket, enhancing the stability of the door hinge. It also provides elastic force for the movable pin to return to its original position, facilitating adjustment of the opening and closing direction.

[0021] Preferably, the movable pins on the horizontal door opening assembly and the movable pins on the adjacent vertical door opening assembly are provided with clearance grooves at their intersections, and the two movable pins intersect through the clearance grooves.

[0022] In this design, the clearance groove effectively eliminates interference problems when the moving pins move in different directions, ensuring that each component of the four-way opening mechanism works independently and improving the overall structure's coordination and reliability.

[0023] Preferably, when the lever is turned so that the lever pushes two movable pins along the guide sleeve into the corresponding sockets via two connecting rods, the box door is hinged to the distribution box body via the two movable pins, so that the box door can be opened around the two movable pins;

[0024] In this setup, the door and the distribution box are quickly hinged together by the linkage of the lever, connecting rod and movable pin, and the rotation axis of the door opening and closing is clearly defined, so that the door can be opened smoothly in the selected direction.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This distribution box door structure, featuring a self-adjusting closing direction function, utilizes a four-way opening mechanism. The longitudinal and transverse opening components are positioned on the inner wall of the door. During operation, simply moving a lever on one side drives the corresponding movable pin to precisely insert into the socket of the distribution box, allowing the door to rotate and open / close around the movable pin. By switching between different directions of the longitudinal and transverse opening components, the door can be flexibly opened in four directions: left / right and up / down. This effectively adapts to various complex installation environments and diverse operational needs, enhancing the flexibility and convenience of using the distribution box.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1-9The distribution box door structure with self-adjusting closing direction function includes a distribution box body 100. The front end of the distribution box body 100 is provided with a door 110. A four-way opening mechanism 200 is installed on the inner wall of the door 110. The four-way opening mechanism 200 includes a pair of longitudinal opening components 210 respectively disposed on the inner wall edges of the top and bottom sides of the door 110, a pair of transverse opening components 220 respectively disposed on the inner wall edges of the left and right sides of the door 110, and four locking knobs 230 rotatably connected to the outside of the door 110. The longitudinal opening components 210 are used to control the longitudinal opening and closing of the door 110, and the transverse opening components 220 are used to control the transverse opening and closing of the door 110. By integrating the four-way opening mechanism 200 into the inner wall of the door 110, the layout of the longitudinal opening components 210 and the transverse opening components 220 provides a basis for opening and closing control in multiple directions for the door. The locking knobs 230 are used to fix the selected opening and closing direction.

[0041] like Figure 1 , Figures 3-6 As shown, in this utility model, the longitudinal door opening assembly 210 includes a lever 211 slidably connected to the door 110, two connecting rods 212 symmetrically hinged to the bottom end of the lever 211, a movable pin 213 hinged to the end of the connecting rod 212, and a guide sleeve 214 sleeved on the outside of the movable pin 213 and slidably connected to the movable pin 213. The guide sleeve 214 is fixedly connected to the door 110. The structure of the transverse door opening assembly 220 is the same as that of the longitudinal door opening assembly 210, except that the longitudinal door opening assembly 210 is adapted to the transverse length of the door 110, and the transverse door opening assembly 220 is adapted to the longitudinal height of the door 110. The bottom end of the lever 211 is provided with a base plate 2111, and the beginning ends of the two connecting rods 212 are respectively hinged to the beginning and end ends of the base plate 2111. The transmission structure consisting of the lever 211, connecting rod 212, movable pin 213 and guide sleeve 214 enables the movable pin 213 to move along the guide sleeve 214 via the connecting rod 212 when the lever 211 is turned. The different lengths of the longitudinal door opening assembly 210 and the transverse door opening assembly 220 ensure that the assembly fits the dimensions of the cabinet door and provides stable support for opening and closing operations in different directions.

[0042] like Figure 2 and Figure 3 As shown, specifically, the two outer corners of the inner wall of the distribution box 100 are provided with socket holes 120. When the movable pin 213 extends outward from the guide sleeve 214, it can be inserted into the corresponding socket hole 120. The cooperation between the socket hole 120 and the movable pin 213 enables the box door 110 to rotate and open and close around the point after the movable pin is inserted into the socket hole, thus completing the hinge action.

[0043] like Figure 4As shown, furthermore, the inner wall of the door 110 is provided with four limiting blocks 111, which correspond to the positions of the four-way opening mechanism 200 and the longitudinal opening assembly 210, respectively. The lever 211 has a waist-shaped groove 2112, through which the limiting blocks 111 pass. The cross-section of the limiting block 111 is T-shaped, and the protruding T-shaped edge of the limiting block 111 restricts the lever 211 between its outer edge and the inner wall of the door 110. The design of the limiting blocks 111 and the waist-shaped groove 2112 limits the range of motion of the lever 211, ensuring that the lever 211 will not deviate from the predetermined track during sliding, thus ensuring the stability of the longitudinal opening assembly 210.

[0044] like Figures 3-6 As shown, the top of the lever 211 is equipped with a lever 2113, the end of which passes through the door 110. The door 110 has four movable slots 112 for the four levers 2113. By moving the levers 2113 into their respective slots 112, the levers 2113 can drive the levers 2111 on the corresponding longitudinal door opening assembly 210 or transverse door opening assembly 220. The levers 2113 and the movable slots 112 provide convenient operating components for the user. By moving the levers 2113, the levers 2111 can be driven, thereby controlling the movement of the door opening assembly and adjusting the opening and closing direction of the door.

[0045] like Figures 5-7 As shown, it is worth noting that a stop plate 2131 is provided on the outer surface of the first end of the movable pin 213. A spring 2132 is sleeved on the outside of the movable pin 213 between the stop plate 2131 and the guide sleeve 214. The spring 2132 is in a pre-tightened state. The pre-tightened design of the spring 2132 allows the spring 2132 to provide a restoring elastic force when the hinge needs to be released, so that the movable pin 213 can be withdrawn from the insertion hole 120 under the action of the spring 2132. This prevents the movable pins 213 on other longitudinal door opening components 210 and transverse door opening components 220 from being accidentally inserted into the insertion hole 120, which would cause the door 110 to be blocked from opening.

[0046] like Figure 9 As shown, it is worth noting that the movable pins 213 on the horizontal opening assembly 220 and the adjacent vertical opening assembly 210 both have clearance grooves 2133 at their intersections. These two movable pins 213 intersect through the clearance grooves 2133. The design of the clearance grooves 2133 effectively avoids interference between the movable pins 213 of the horizontal opening assembly 220 and the vertical opening assembly 210 during movement, ensuring that each component of the four-way opening mechanism 200 can operate independently and normally.

[0047] It should be added that when the lever 211 is turned, causing it to push two movable pins 213 along the guide sleeve 214 into the corresponding sockets 120 via the two connecting rods 212, the box door 110 is hinged to the distribution box 100 via the two movable pins 213, allowing the box door 110 to open around the two movable pins 213. Through the linkage of the lever 211, connecting rods 212, and movable pins 213, the hinge of the box door 110 to the distribution box 100 is achieved, determining the opening and closing axis of the box door, thereby realizing opening in the corresponding direction.

[0048] like Figure 3 and Figure 8 As shown, the positions of the locking knob 230 correspond to the positions of the longitudinal door opening assembly 210 and the transverse door opening assembly 220, respectively. The bottom end of the locking knob 230 is provided with a hanging plate 231 with a hanging groove. When the locking knob 230 is rotated to hook the hanging plate 231 onto the corresponding lever 2113, the longitudinal door opening assembly 210 or the transverse door opening assembly 220 corresponding to that lever 2113 is locked by the hanging plate 231. The cooperation between the locking knob 230 and the hanging plate 231, after selecting the door opening direction, secures the door opening assembly by hooking the lever 2113, preventing accidental movement and ensuring the stability of the door's open / closed state.

[0049] In this embodiment, the distribution box door structure with self-adjusting closing direction function is used as follows: First, the opening and closing direction of the box door is determined according to the installation environment and operational requirements; then, the corresponding lever 2113 is moved, causing the lever 2113 to drive the lever plate 211 through the connecting rod 212 to push the movable pin 213 into the socket 120 of the distribution box body 100, thus completing the hinge of the box door; finally, the locking knob 230 is rotated, causing the hanging plate 231 to engage with the lever 2113, locking the selected door opening component, so that the movable pin 213 is always inserted into the socket 120. At this time, the box door 110 can rotate to open and close around the movable pin 213 inserted into the distribution box body 100.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
