Description

Technical Field

[0001] This invention relates to the field of elevator cabinet door technology, and in particular to an elevator control cabinet door structure that is easy to fix. Background Technology

[0002] As a key component in elevator operation, the control cabinet contains crucial parts such as the main control board and relays, thus frequently requiring testing, experimentation, and maintenance. Currently, control cabinet doors come in two types: 1. Doors with a rotating mechanism on the side, allowing direct opening but without a fixing device; 2. Doors with a hoist hole, secured by screws on one side of the control cabinet body, requiring the door to be removed and placed in an open area before opening.

[0003] However, the above two types of cabinet door structures have the following technical defects:

[0004] 1. The cabinet door has a rotating device on the side, which cannot be fixed. This may cause the control cabinet door to close unexpectedly, affecting the testing or maintenance process.

[0005] 2. The cabinet door has a hoist hole and is fixed with screws. Each time, the cabinet door needs to be removed and then hung back on the control cabinet after the operation, which is a cumbersome process. Summary of the Invention

[0006] The purpose of this invention is to provide an elevator control cabinet door structure that is easy to fix, in order to solve the above-mentioned technical problems.

[0007] The technical solution adopted in this invention is as follows:

[0008] An elevator control cabinet door structure that is easy to fix includes a control cabinet and a door located at the top of the control cabinet. It also includes a rotating disk and a positioning part for cooperating with the rotating disk. The rotating disk is located on both sides of one end of the door and is rotatably connected to the side wall of the control cabinet. The positioning part is movably provided on the side wall of the control cabinet. The positioning part cooperates with the rotating disk to automatically fix the door at a specified angle.

[0009] Preferably, the rotating disk has an opening on one side, with one side wall of the opening being a thin wall and the other side wall of the opening being a thick wall.

[0010] As a further preferred embodiment, the rotating disk is also provided with a first sliding groove and a second sliding groove, the first sliding groove and the second sliding groove being connected, and the first sliding groove and the second sliding groove being connected to the opening respectively.

[0011] As a further preferred embodiment, the length of the first groove along the radial direction of the rotating disk is greater than the length of the second groove along the radial direction of the rotating disk.

[0012] As a further preferred embodiment, the connection position between the first slide and the second slide is provided with a pointed end.

[0013] Preferably, the positioning part is a positioning block, and the positioning block has V-shaped grooves on both sides, which can engage with the tip and the end of the thick wall.

[0014] Preferably, the rotating disk is fixedly connected to the cabinet door, and the middle part of the rotating disk is rotatably connected to the side wall of the control cabinet through a first connector.

[0015] Preferably, the positioning part is connected to the side wall of the control cabinet via a second connector.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] In this invention, the cooperation between the rotating disk and the positioning part prevents the cabinet door from being unable to be fixed during testing or maintenance work, thus avoiding any impact on the testing or maintenance work. In addition, the cabinet door structure of this control cabinet can fix the cabinet door simply by opening and closing it, without the need for any other operations, making the fixing more efficient and simple.

Figure 1 ; Figure 8 This is a schematic diagram illustrating the cooperation between the rotating disc and the positioning part during the cabinet door fixing and unloading process in this invention. Figure 2 Please see. Figures 1 to 8 The diagram illustrates a preferred embodiment of an elevator control cabinet door structure designed for easy fixation. The structure includes a control cabinet 1 and a door 2 located at the top of the control cabinet 1. It also includes a rotating disk 3 and a positioning part 4 that cooperates with the rotating disk 3. The rotating disk 3 is located on both sides of one end of the door 2 and is rotatably connected to the side wall of the control cabinet 1. The positioning part 4 is movably mounted on the side wall of the control cabinet 1. The positioning part 4 cooperates with the rotating disk 3 to automatically fix the door 2 at a specified angle. In this embodiment, see [reference needed]. Figure 2 As shown, the positioning part 4 can enter the rotating disk 3 and engage with it, so that the cabinet door 2 can be fixed at a specified angle during rotation, such as when the cabinet door 2 is fully open (100°) and when the cabinet door 2 is open 90°. When the cabinet door 2 is rotated to these two specified angles (100° and 90°), it can be automatically fixed without the action of external force, without the need for additional fixing devices to fix the cabinet door 2, and without the need for other operations, thus enabling the cabinet door 2 to be quickly fixed.

[0031] Furthermore, as a preferred embodiment, an opening 5 is provided on one side of the rotating disk 3, with one side wall of the opening 5 being a thin wall 10 and the other side wall of the opening 5 being a thick wall 11. See also Figure 2 As shown, the rotating disk 3 is also provided with a first sliding groove 6 and a second sliding groove 7. The first sliding groove 6 and the second sliding groove 7 are connected, and both the first sliding groove 6 and the second sliding groove 7 are connected to the opening 5. The first sliding groove 6 is located near the thick wall 11, and the second sliding groove 7 is located near the thin wall 10. The positioning part 4 can move within the first sliding groove 6 and the second sliding groove 7. When the cabinet door 2 is rotated, the cabinet door 2 will drive the rotating disk 3 to rotate. At this time, the side walls of the first sliding groove 6 and the second sliding groove 7 on the rotating disk 3 will contact the positioning part 4, and can drive the positioning part 4 to rotate at a certain angle, for cooperation with the end of the thick wall 11, the inner wall of the second sliding groove 7, and the tip 8. For details, please refer to [reference needed]. Figure 2 , Figure 4 and Figure 6 As shown.

[0032] Furthermore, as a preferred embodiment, the length of the first slide groove 6 along the radial direction of the rotating disk 3 is greater than the length of the second slide groove 7 along the radial direction of the rotating disk 3. See also... Figure 7 and Figure 8 As shown, the width of the first slide groove 6 is greater than the width of the second slide groove 7, and the width of the first slide groove 6 is wider, so as to cooperate with the positioning part 4, so that the positioning part 4 can rotate inside the first slide groove 6, which facilitates the separation of the V-shaped groove 9 on the positioning part 4 from the tip part 8 or the end of the thick wall 11, and realizes the unlocking action after fixing.

[0033] Furthermore, as a preferred embodiment, a pointed portion 8 is provided at the connection position between the first slide groove 6 and the second slide groove 7. The position and shape of the pointed portion 8 can be found in [reference needed]. Figure 2 As shown.

[0034] Furthermore, as a preferred embodiment, the positioning part 4 is a positioning block, and V-shaped grooves 9 are provided on both sides of the positioning block. The V-shaped grooves 9 can engage with the ends of the pointed part 8 and the thick wall 11. In this embodiment, the pointed part 8 and the ends of the thick wall 11 can enter into the V-shaped grooves 9, thereby limiting the angle of the rotating disk 3 and fixing the position of the cabinet door 2. Specifically, when the cabinet door 2 is opened to 90°, see... Figure 6 As shown, when the pointed part 8 is inserted into one of the V-shaped slots 9, the cabinet door 2 is open at 90°. At this time, the V-shaped slot 9 and the pointed part 8 cooperate to fix the angle of the cabinet door 2. When the cabinet door 2 is opened further, see... Figure 4 As shown, the pointed end 8 of the thick wall 11 enters the V-shaped groove 9 to fix the rotating disk 3, thereby fixing the position of the cabinet door 2.

[0035] Furthermore, as a preferred embodiment, the rotating disk 3 is fixedly connected to the cabinet door 2, and the middle part of the rotating disk 3 is rotatably connected to the side wall of the control cabinet 1 through the first connector.

[0036] Furthermore, as a preferred embodiment, the positioning part 4 is connected to the side wall of the control cabinet 1 via a second connector. In this embodiment, both the first and second connectors are screws, and the tightness of the positioning part 4 can be controlled by rotating the screws, allowing the positioning part 4 to rotate freely. Both the center of the rotating disk 3 and the center of the positioning part 4 have mounting holes for installing screws.

[0037] In this embodiment, see Figure 2 As shown, when the cabinet door 2 is fully closed, the positioning part 4 is completely located within the second slide groove 7 and abuts against the inner wall of the second slide groove 7. At this time, both the rotating disk 3 and the positioning part 4 are in their initial states. See also Figure 1 As shown, when cabinet door 2 needs to be opened, it can be rotated counterclockwise to fully open to 100°. During this process, positioning part 4 and rotating disk 3 rotate counterclockwise simultaneously until the end of thick wall 11 is inserted into V-shaped groove 9, preventing cabinet door 2 from being over-opened. When cabinet door 2 is slightly closed, and the angle between cabinet door 2 and the upper surface of control cabinet 1 is 90°, the tip 8 on rotating disk 3 will insert into one of the V-shaped grooves 9, thus fixing the angle of cabinet door 2.

[0038] In this embodiment, when the cabinet door 2 is rotated to 90° and 100°, a slight sound is produced when the pointed end 8 or the thick-walled end 11 is inserted into the V-shaped groove 9, serving as a notification. When opening the cabinet door 2, it is necessary to first fully open the cabinet door 2, and then rotate the cabinet door 2 to 90° as needed.

[0039] When cabinet door 2 is in the 90° position, if it is necessary to close cabinet door 2, cabinet door 2 can be rotated slightly counterclockwise so that cabinet door 2 is in the position greater than 90° but less than 100°, about 95°. At this time, the tip 8 will drive the positioning part 4 to rotate and disengage from the V-shaped groove 9, releasing the fixation on the rotating disk 3. The end of the thick wall 11 will press against the side wall of the positioning part 4, and then be rotated counterclockwise so that the end of the thick wall 11 drives the positioning part 4 to rotate counterclockwise, preparing to completely release the fixation on the rotating disk 3.

[0040] Then continue to rotate cabinet door 2 clockwise, so that the rotating disk 3 and the positioning part 4 are in the correct position. Figure 8 As shown, the positioning part 4 is in the initial state. Then, by rotating the cabinet door 2 clockwise, the positioning part 4 can enter the second slide groove 7, thereby closing the cabinet door 2.

[0041] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
