Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to a static-dissipating cabinet door transmission sheet metal structure for electrical control cabinets. Background Technology

[0002] An electrical control cabinet is a device that assembles switching equipment, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment.

[0003] Currently, most control cabinets are connected to the cabinet body via ordinary hinges. Although both the cabinet door and the cabinet body are made of metal, the surface is coated with an insulating varnish layer, and there may be oil or oxidation at the hinge connection. This results in less than ideal electrical conductivity between the cabinet door and the cabinet body. Consequently, static electricity from the operator cannot be effectively conducted to the grounded cabinet body through the cabinet door. Discharge is very likely to occur the moment the cabinet door is opened, causing irreversible breakdown damage to sensitive electronic components inside the cabinet, leading to equipment failure and economic losses. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A static-dissipating cabinet door transmission sheet metal structure for an electrical control cabinet includes a cabinet door body, with a cabinet body hinged to the outer side of the cabinet door body, and also includes a first conductive element and a second conductive element, both of which are disposed between the cabinet door body and the cabinet body; wherein, the first conductive element includes an abutment rod and a conductive sheet, the conductive sheet is installed to the outer side of the cabinet body, the abutment rod is installed to the inner wall of the cabinet door body, and the conductive sheet is located on the movement path of the abutment rod.

[0007] As a preferred embodiment of the electrostatic conductive cabinet door transmission sheet metal structure for electrical control cabinets described in this utility model, the second conductive component includes a horizontal bar and a vertical bar, one end of the horizontal bar is installed to the outside of the vertical bar, and the vertical bar is located inside the cabinet and its top end is connected to the cabinet.

[0008] As a preferred embodiment of the electrostatic conductive cabinet door transmission sheet metal structure for electrical control cabinets described in this utility model, wherein: a folding rod installed to the outside of the cabinet is rotatably connected to the conductive sheet, a torsion spring is sleeved on the outside of the folding rod, and one end of the torsion spring is installed to the outside of the conductive sheet.

[0009] As a preferred embodiment of the electrostatic conductive cabinet door transmission sheet metal structure for electrical control cabinets described in this utility model, the contact rod is N-shaped, and the conductive sheet has a chamfer on the side near the contact rod.

[0010] As a preferred embodiment of the electrostatic conductive cabinet door transmission sheet metal structure for electrical control cabinets described in this utility model, a handle is provided on the outer side of the cabinet door body, and an actuating ring that slidably engages with the end of the crossbar is slidably sleeved on the handle.

[0011] As a preferred embodiment of the electrostatic conductive cabinet door transmission sheet metal structure for electrical control cabinets described in this utility model, wherein: the bottom end of the vertical rod is slidably connected to a sliding rod, and the top end of the sliding rod is fitted with a spring located inside the vertical rod.

[0012] As a preferred embodiment of the electrostatic conductive cabinet door transmission sheet metal structure for electrical control cabinets described in this utility model, wherein: a groove is provided on one side of the cabinet body, an insertion hole communicating with the groove is provided inside the cabinet body, and the top end of the vertical rod extends into the insertion hole.

[0013] As a preferred embodiment of the electrostatic conductive cabinet door transmission sheet metal structure for electrical control cabinets described in this utility model, wherein: the bottom end of the sliding rod is embedded with a ball bearing, and the outer side of the ball bearing contacts the groove.

[0015] As a preferred embodiment of the electrostatic conductive cabinet door transmission sheet metal structure for electrical control cabinets described in this utility model, the actuating ring, crossbar, and vertical bar are all made of conductive metal materials.

[0016] The beneficial effects of this utility model are as follows: by setting a vertical bar to limit the opening, the cabinet door can only be opened when the user presses the toggle ring, causing the horizontal bar to drive the vertical bar to descend and separate from the socket. During this process, the static electricity of the human body is introduced into the cabinet body along the toggle ring, horizontal bar and vertical bar, and then discharged by the grounding wire, thus preventing the discharge phenomenon after the door is opened.

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1:

[0029] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a static-dissipating cabinet door transmission sheet metal structure for electrical control cabinets, including a cabinet door body 100, and a cabinet body is hinged to the outside of the cabinet door body 100.

[0030] The cabinet door body 100 is connected to the cabinet body by a hinge, and the user can perform static discharge treatment when opening the cabinet door body 100.

[0031] It also includes a first conductive element 200 and a second conductive element 300, both of which are disposed between the cabinet door body 100 and the cabinet body; wherein, the first conductive element 200 includes an abutment rod 210 and a conductive sheet 220, the conductive sheet 220 is installed on the outside of the cabinet body, the abutment rod 210 is installed on the inner wall of the cabinet door body 100, and the conductive sheet 220 is located on the movement path of the abutment rod 210.

[0032] When the user opens the cabinet door body 100, the second conductive component 300 is used to discharge static electricity.

[0033] Subsequently, during the opening of the cabinet door body 100, when the opening angle is small, the abutment rod 210 will come into contact with the conductive sheet 220. At this time, the static electricity on the user's body is transferred to the cabinet body along the cabinet door body 100, the abutment rod 210, and the conductive sheet 220, and then discharged along the grounding wire.

[0034] It should be noted that the conductive sheet 220 is made of phosphor bronze or beryllium copper, which has good conductivity and a certain degree of elasticity. It can directly contact the contact rod 210 to discharge static electricity, and then reset by its own deformation ability.

[0035] A grounding wire for static electricity discharge is installed at the bottom of the cabinet. This technology is a mature existing technology and will not be described in detail here.

[0036] Example 2:

[0037] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the second conductive component 300 includes a horizontal bar 310 and a vertical bar 320. One end of the horizontal bar 310 is installed to the outside of the vertical bar 320, and the vertical bar 320 is located inside the cabinet and its top end is connected to the cabinet.

[0039] Before the user opens the cabinet door, the vertical rod 320 is connected to the cabinet body. The user needs to move the horizontal rod 310 to lower the vertical rod 320 before the main body of the cabinet door 100 can be opened. During this process, the static electricity of the user's body will be transferred to the cabinet body through the horizontal rod 310 and the vertical rod 320, and then discharged.

[0040] Specifically, a folding rod 221 is rotatably connected to the conductive sheet 220 and installed on the outside of the cabinet. A torsion spring 222 is sleeved on the outside of the folding rod 221, and one end of the torsion spring 222 is installed on the outside of the conductive sheet 220.

[0041] The conductive sheet 220 is supported by a folding rod 221. During the discharge process, the conductive sheet 220 will rotate after the contact rod 210 and the conductive sheet 220 come into contact. After the two separate, the conductive sheet 220 can be driven to reset by the torsion spring 222.

[0042] This discharge method can reduce the contact force between the conductive sheet 220 and the contact rod 210, and extend the service life of the conductive sheet 220.

[0043] Specifically, the contact rod 210 is N-shaped, and the conductive sheet 220 has a chamfer on the side near the contact rod 210.

[0044] This reduces wear when the two come into contact, extending service life without affecting electrostatic transfer.

[0045] Example 3:

[0046] Reference Figures 1-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, a handle is provided on the outside of the cabinet door body 100, and an actuating ring 110 that is connected to the end of the crossbar 310 is slidably sleeved on the handle.

[0048] With the toggle ring 110, when the user holds the handle, they can press the toggle ring 110 with their fingers, so that the vertical rod 320 moves accordingly, quickly completing the opening operation of the cabinet door body 100, which is more efficient.

[0049] Specifically, a sliding rod 321 is slidably connected to the bottom end of the vertical rod 320, and a spring 322 inside the vertical rod 320 is installed at the top end of the sliding rod 321; a groove is provided on one side of the cabinet, and an insertion hole communicating with the groove is provided inside the cabinet, with the top end of the vertical rod 320 extending into the insertion hole.

[0050] A spring 322 is used in conjunction with a sliding rod 321 to push the vertical rod 320 upward, thereby improving the stability of the connection between the vertical rod 320 and the insertion hole inside the cabinet and reducing the occurrence of accidental opening of the cabinet door body 100.

[0051] Specifically, a ball bearing is embedded at the bottom of the sliding rod 321, and the outer side of the ball bearing contacts the groove.

[0052] By utilizing the ball bearing mechanism, when the vertical rod 320 separates from the groove, the ball bearing is used to reduce wear between the sliding rod 321 and the cabinet body, thus extending its service life.

[0053] Specifically, the top of the vertical rod 320 is provided with a bevel.

[0054] By utilizing the inclined surface, when the cabinet door body 100 is closed, the inclined surface will abut against the groove opening on the cabinet body, and then drive the vertical rod 320 to descend under pressure, quickly completing the closing operation of the cabinet door body 100. After closing, the spring 322 will push the vertical rod 320 to connect with the socket.

[0055] Specifically, the toggle ring 110, the horizontal bar 310, and the vertical bar 320 are all made of conductive metal materials.

[0056] The toggle ring 110, the horizontal bar 310, and the vertical bar 320 can be made of copper and have good electrical conductivity.

[0057] During use, the user holds the handle and then presses the toggle ring 110 downwards. At this time, static electricity is transferred to the cabinet body through the horizontal bar 310 and the vertical bar 320, completing the first static discharge. Then, the user pulls the cabinet door body 100. During the opening of the cabinet door body 100, the contact rod 210 contacts the conductive plate 220, transferring static electricity to the cabinet body through the contact rod 210 and the conductive plate 220, performing the second static discharge. This provides a pre-discharge protection function before the operator may touch the internal components. The entire device completes static discharge through a dual discharge method during the opening of the cabinet door body 100, reducing the discharge phenomenon after the door is opened, reducing irreversible breakdown damage to sensitive electronic components inside the cabinet, reducing equipment failure rate, and reducing economic losses.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
