Description

Technical Field

[0001] The utility model relates to the technical field of frequency converter cabinets, in particular to a door anti - sagging structure. Background Art

[0002] A frequency converter is a power control device that applies frequency conversion technology and microelectronics technology to control an AC motor by changing the working power frequency of the motor. Frequency converters are generally used in cabinets, and the cabinet door is supported by hinges on only one side, which will cause the side of the cabinet door far from the hinge to sag to varying degrees, especially when the cabinet door is wider or the devices installed on the cabinet door are heavier.

[0003] When the sag is relatively small, although it does not affect the normal closing of the door, multiple cabinet doors on the same side often appear uneven, and the sag amounts of each cabinet door are inconsistent, seriously affecting the overall appearance of the cabinet. When the sag amount is relatively large, it may cause the door not to close or not to close tightly, posing a potential safety hazard for electricity use.

[0004] Currently, most frequency converter cabinets either do not take measures to prevent the cabinet door from sagging or use a single - side anti - sagging structure for correction. However, there are errors in both processing and assembly, and the single - side anti - sagging often fails to prevent the cabinet door from sagging. Summary of the Utility Model

[0005] (1) Technical Problem

[0006] The purpose of the utility model is to provide a door anti - sagging structure to solve the problem that in the prior art, no anti - sagging structure is used to correct the cabinet door or the single - side anti - sagging structure fails to correct the cabinet door during closing.

[0007] (2) Technical Solution

[0008] To achieve the above purpose, the utility model provides the following technical solution:

[0009] A door anti - sagging structure includes a cabinet door and a cabinet body. The cabinet body includes a rotating side and a closing side. The cabinet door is rotatably installed on the rotating side of the cabinet body. The cabinet door and the cabinet body are provided with a first guiding structure at the top of the closing side and a second guiding structure at the bottom of the closing side. When the cabinet door is closed, both the first guiding structure and the second guiding structure are used to guide the part of the cabinet door on the closing side to move upward.

[0010] Preferably, the first guiding structure includes a first wedge block fixed on the cabinet body and a second wedge block fixed on the cabinet door. The first wedge block is provided with a first wedge surface inclined towards the cabinet door side, and the second wedge block is provided with a second wedge surface cooperating with the first wedge surface.

[0011] Preferably, the included angles between the first wedge surface, the second wedge surface and the horizontal plane are 30° to 45°.

[0012] Preferably, the materials of the first wedge block and the second wedge block are both polytetrafluoroethylene.

[0013] Preferably, the second guiding structure includes a mounting bracket fixed on the cabinet door and a caster rotatably arranged on the mounting bracket; a plastic sheet is fixed on the cabinet body; when the cabinet door is closed, the upper surface of the plastic sheet is used to support the caster.

[0015] Preferably, the material of the plastic sheet is polytetrafluoroethylene.

[0016] Preferably, a door lock structure for locking the cabinet door is provided on the cabinet door at the closing side.

[0017] (III) Beneficial effects

[0018] By providing a first guiding structure at the top of the cabinet door on the closing side of the cabinet body and a second guiding structure at the bottom, during the closing process of the cabinet door, an upward movement trend is formed for the cabinet door through the first guiding structure, and the bottom is further moved upward by using the second guiding structure, so that the cabinet door can move in a combined force when moving upward at the closing side, effectively ensuring that the two corner positions of the cabinet door are corrected to be flush with the cabinet body; effectively avoiding the situation that the cabinet door is skewed due to unilateral correction in the prior art;

[0019] After correction, when the cabinet door is closed, the periphery of the cabinet door is flush with the cabinet body, and at the same time, the risk of rotation damping caused by deformation of the cabinet door can also be avoided. Description of the drawings

[0020] Figure 1 is a schematic structural diagram of the installation of the cabinet door and the cabinet body in the embodiment of the present invention;

[0021] Figure 2 is Figure 1 a partial enlarged structural diagram at A in

[0022] Figure 3 is Figure 1 a partial enlarged structural diagram at B in

[0023] In Figures 1 to 3 the corresponding relationship between the component names or lines and the drawing reference numerals is as follows:

[0024] Cabinet door 1, cabinet body 2, first guiding structure 3, first wedge block 31, first wedge surface 32, second wedge block 33, second wedge surface 34, second guiding structure 4, mounting bracket 41, casters 42, plastic sheet 43, guiding inclined surface 44. Detailed implementation mode

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] See Figures 1 - 3 As shown, in the embodiment of the present invention, a structure for preventing the cabinet door 1 from sagging is proposed, which includes a cabinet door 1 and a cabinet body 2. The cabinet body 2 includes a rotating side and a closing side. The cabinet door 1 is rotatably installed on the rotating side of the cabinet body 2. Specifically, a first guiding structure 3 is provided at the top of the closing side on the cabinet door 1 and the cabinet body 2, and a second guiding structure 4 is provided at the bottom of the closing side; when the cabinet door 1 is closed, both the first guiding structure 3 and the second guiding structure 4 are used to guide the part of the cabinet door 1 on the closing side to move upward.

[0027] After the cabinet door 1 is deformed, the parts that are not tightly closed are mainly located on the closing side. Generally, the cabinet body 2 will sag downward on the closing side, which affects the locking operation when closing on the one hand, and on the other hand, the cabinet door 1 looks uneven from the outside.

[0028] Therefore, when closing the door, the top of the cabinet door 1 is corrected to move upward through the first guiding structure 3, and at the same time, the bottom of the cabinet door 1 is corrected to move upward through the second guiding structure 4, so that the cabinet door 1 has a resultant force on the closing side and moves upward for correction at the same time, which can ensure that the corner of the cabinet door 1 remains flush with the cabinet body 2, and there is no sagging situation for the entire cabinet door 1 on the outside, and it has a good protective effect on the rotating connection structure on the rotating side, avoiding the damping situation caused by deformation.

[0029] Specifically, the first guiding structure 3 includes a first wedge block 31 fixed on the cabinet body 2 and a second wedge block 33 fixed on the cabinet door 1. The first wedge block 31 is provided with a first wedge surface 32 inclined toward the cabinet door 1. The second wedge block 33 is provided with a second wedge surface 34 that cooperates with the first wedge surface 32. During the closing process of the cabinet door 1, the second wedge surface 34 plays a guiding role, so that the upper part of the cabinet door 1 moves upward under the guiding action of the first wedge surface 32, and when the first wedge surface 32 and the second wedge surface 34 are completely attached, the complete top of the cabinet door 1 is corrected.

[0030] Among them, the included angles between the first wedge surface 32, the second wedge surface 34 and the horizontal plane are 30° to 45°. The included angle of the inclined surface should not be too large or too small. Just keeping the cabinet door 1 flush with the cabinet body 2 after correction can avoid deformation of the cabinet door 1 caused by excessive correction.

[0031] In order to reduce the small friction when the first wedge surface 32 and the second wedge surface 34 slide and cooperate with each other, the materials of the first wedge block 31 and the second wedge block 33 are both polytetrafluoroethylene.

[0032] Specifically, the second guiding structure 4 includes a mounting bracket 41 fixed on the cabinet door 1 and a caster 42 rotatably arranged on the mounting bracket 41; a plastic sheet 43 is fixed on the cabinet body 2. When the cabinet door 1 is closed, the upper surface of the plastic sheet 43 is used to support the caster 42; when the cabinet door 1 is closed, the caster 42 is supported by the plastic sheet 43 to correct the bottom of the cabinet door 1. At the same time, since the caster 42 rolls during closing, it can promote the rapid corrective sliding of the first guiding structure 3.

[0033] In order to make the caster 42 have a small resistance during the process of moving onto the plastic sheet 43, a guiding inclined surface 44 for guiding the movement of the caster 42 is provided on the plastic sheet 43, and the guiding inclined surface 44 is used for guiding when the cabinet door 1 starts to close.

[0034] Similarly, in order to reduce the friction, the material of the plastic sheet 43 is polytetrafluoroethylene.

[0035] Specifically, a door lock structure for locking the cabinet door 1 is provided on the cabinet door 1 at the closing side. The door lock structure can also be arranged on the cabinet door 1 to achieve stable locking after the cabinet door 1 is corrected.
