Description

Technical Field

[0001] This utility model relates to the field of switch cabinet accessories technology, and in particular to a combined switch cabinet header structure. Background Technology

[0002] The header of a switchgear is a panel-like device installed on the top front of the switchgear to display the switchgear model and cabinet number. It is generally made of cold-rolled steel sheet or aluminum profile.

[0003] Most existing eyebrow-shaped switches are one-piece structures. When the eyebrow-shaped switch is damaged or needs to be replaced, the entire switch must be replaced, which is relatively expensive. In addition, the mounting hole positions of the eyebrow-shaped switch cannot be adjusted, resulting in poor versatility. This often leads to a mismatch between the mounting hole positions of the eyebrow-shaped switch and the mounting hole positions of the switch cabinet during maintenance, requiring on-site drilling and affecting work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a combined switch cabinet header device to solve the problems of high replacement and maintenance costs, inability to adjust the mounting hole position, and poor versatility of integrated header structures.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A modular switchgear header structure includes header plates arranged opposite each other, with a lettering plate clamped between the header plates. Baffles adapted to the lettering plates are clamped at the left and right ends of the two header plates. An mounting plate is provided on the inner sidewall of the header plates, with a gap between the mounting plate and the rear end of the header plates. An installation groove is provided on the mounting plate, and an elastic fastener is slidably mounted on the installation groove. The elastic fastener includes a main horizontal plate and a mounting component adapted to the installation groove. An installation hole is provided on the main horizontal plate, and a protrusion adapted to the size of the mounting component is provided at the lower end of the mounting plate. A mounting opening adapted to the mounting component is provided on the protrusion, and the mounting opening communicates with the installation groove.

[0007] Furthermore, the mounting component includes an arc-shaped connecting plate, a secondary horizontal plate, and a limiting protrusion arranged sequentially. The arc-shaped connecting plate is connected to the end of the main horizontal plate. The main horizontal plate and the mounting component are integrally formed. The size of the secondary horizontal plate is adapted to the size of the bottom beam of the mounting groove formed by the mounting plate. The distance from the limiting protrusion to the main horizontal plate is less than the distance from the secondary horizontal plate to the main horizontal plate.

[0008] Furthermore, the front end of the eyebrow plate is provided with a folded edge, and the inner side wall of the eyebrow plate is also provided with a front limiting plate. The front limiting plate and the folded edge form a slot, which is compatible with the lettering plate.

[0009] Furthermore, both ends of the eyebrow plate are equipped with mounting plates. The front end of the mounting plate is connected to the front limit plate, and the rear end of the mounting plate is connected to the mounting plate. The mounting plate has a locking hole for fixing the baffle.

[0010] Furthermore, the baffle is provided with a card block that fits the card hole, and the end of the card block passes through the card hole and is provided with an anti-detachment head. The baffle, card block and anti-detachment head are integrally formed.

[0011] This utility model has the following advantages:

[0012] 1. The modular structure allows for individual component replacement during maintenance, eliminating the need for complete replacement and reducing maintenance costs.

[0013] 2. The elastic fastener and the mounting plate are designed with a sliding fit, which allows the position of the elastic fastener on the mounting plate to be adjusted, effectively solving the problem of mismatch in the mounting hole position. After installation and fixing, the connection between the header and the switch cabinet is more stable and reliable. Attached Figure Description

[0027] refer to Figure 1-6 As shown, one embodiment of this utility model is as follows:

[0028] A modular switchgear header structure includes header plates 1 arranged opposite each other, with a lettering plate 2 clamped between the header plates 1. Baffles 3, adapted to the lettering plates 2, are clamped at the left and right ends of the two header plates 1. An mounting plate 4 is provided on the inner side wall of each header plate 1, with a gap between the mounting plate 4 and the rear end of each header plate 1. An mounting groove 5 is provided on the mounting plate 4, and an elastic fastener is slidably mounted on the mounting groove 5. The elastic fastener includes a main horizontal plate 6 and a mounting component adapted to the mounting groove 5. An installation hole 7 is provided on the main horizontal plate 6. A protrusion 8, adapted to the size of the mounting component, is provided at the lower end of the mounting plate 4. A mounting opening 9, adapted to the mounting component, is provided on the protrusion 8, and the mounting opening 9 communicates with the mounting groove 5.

[0029] In use, select the corresponding number of elastic fasteners according to the number of mounting holes on the switch cabinet and hang them on the eyebrow plate 1. Then install the baffle 3 at one end to achieve pre-assembly of the device, so as to facilitate the connection and fixation of the elastic fasteners to the switch cabinet through threaded connection. Then, insert the engraved plate 2 with the switch cabinet information printed on it between the two eyebrow plates 1. Finally, install the baffle 3 at the other end to achieve the installation and fixation of the eyebrow.

[0030] The design employs a modular structure, allowing for individual component replacement during maintenance, eliminating the need for complete system replacement and reducing maintenance costs. However, since the replacement eyebrow section is often not an original part, mismatches in mounting hole positions can occur. Because this application utilizes a modular design, this embodiment further incorporates a sliding fit between the elastic fastener and the mounting plate 4, enabling adjustable positioning of the elastic fastener on the mounting plate and effectively resolving the mounting hole mismatch issue. A gap exists between the rear end of the mounting plate 4 and the eyebrow section clamping plate 1. After connection and fixation, the main horizontal plate 6 forms an arc-shaped structure, with the mounting component secured between the mounting plate 4 and the switch cabinet to prevent detachment, effectively ensuring a stable and reliable connection between the eyebrow section and the switch cabinet.

[0031] Specifically, the mounting component includes an arc-shaped connecting plate 10, a secondary horizontal plate 11, and a limiting protrusion 12 arranged sequentially. The arc-shaped connecting plate 10 is connected to the end of the main horizontal plate 6. The main horizontal plate 6 is integrally formed with the mounting component. The size of the secondary horizontal plate 11 is adapted to the size of the bottom beam 41 of the mounting slide 5 formed by the mounting plate 4. The distance from the limiting protrusion 12 to the main horizontal plate 6 is less than the distance from the secondary horizontal plate 11 to the main horizontal plate 6.

[0032] Since the mounting components need to be mounted on the mounting groove, the width needs to be larger than the mounting opening 9 of the mounting groove. If the bottom beam 41 of the mounting plate is broken, although the mounting components can be mounted, it will reduce the structural strength. Therefore, in this embodiment, the camera-outward protrusion 8 and the mounting opening 9 are provided, which can both meet the assembly of the mounting components and ensure the structural strength of the mounting plate.

[0033] After the arc-shaped connecting plate 10, the secondary horizontal plate 11, and the limiting protrusion 12 pass through the mounting port 9, the secondary horizontal plate 11, the limiting protrusion 12, and the main horizontal plate 6 are located on both sides of the mounting plate, thereby realizing the mounting of the elastic fastener. The position of the elastic fastener on the mounting plate 4 can be adjusted according to the position of the mounting hole, which is highly practical.

[0034] In practice, the width of the gap between the mounting plate 4 and the rear end of the eyebrow clamping plate 1 is consistent with the thickness of the secondary horizontal plate. After threaded connection, the secondary horizontal plate 11 can be securely clamped between the switch cabinet and the bottom beam 41, effectively preventing it from falling off and ensuring good installation stability.

[0035] It is understood that the arc-shaped connection 10 referred to in this embodiment can also be replaced with a connection plate of other structures, as long as it can pass over the mounting groove 5.

[0036] To facilitate the limiting protrusion 12 passing over the protrusion 8 from the mounting port 9, a transfer groove 81 is provided on the protrusion 8.

[0037] Furthermore, the front end of the eyebrow plate 1 is provided with a folded edge 13, and the inner side wall of the eyebrow plate 1 is also provided with a front limiting plate 14. The front limiting plate 14 and the folded edge 13 form a slot, which is adapted to the lettering plate 2. The slot designed by the folded edge 3 and the front limiting plate 14 is used to hold the lettering plate. The structure is simple and facilitates the assembly of the lettering plate 2.

[0038] In practice, the lower end of the front limiting plate 14 and the lower end of the bottom beam 41 of the mounting plate 4 are on the same horizontal plane.

[0039] In this embodiment, the eyebrow clip plate 1 is provided with clip plates 15 at both the left and right ends. The front end of the clip plate 15 is connected to the front limiting plate 14, and the rear end of the clip plate 15 is connected to the mounting plate 4. The clip plate 15 is provided with clip holes 16 for fixing the baffle 3.

[0040] The baffle 3 is provided with a locking block 17 adapted to the locking hole 16. The end of the locking block 17 passes through the locking hole 16 and is provided with an anti-detachment head 18. The baffle 3, the locking block 17, and the anti-detachment head 18 are integrally formed.

[0041] Specifically, the baffle 3, the locking block 17, and the anti-detachment head 18 are made of rubber / plastic materials for braking. In this embodiment, all other components are made of metal. The anti-detachment head 18 has a hemispherical or spherical structure to facilitate passing through the locking hole 16. The number and position of the locking holes 16 can be set according to the actual situation. For example, in this embodiment, the number of locking blocks 16 is set to two.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
