Description

Technical Field

[0001] The utility model belongs to the technical field of emergency lighting power supply equipment, and more specifically, particularly relates to a protective device for emergency lighting centralized power supply. Background Art

[0002] Emergency lighting centralized power supply is a device that provides power support for emergency lighting fixtures in emergency situations. Emergency lighting centralized power supply usually consists of battery pack, charging module, inverter module, monitoring module, display, operation panel, shell and heat dissipation system. The shell usually protects the internal components and prevents dust, water and fire. The heat dissipation system is used to dissipate the heat generated by the internal components of the power supply when they are working, ensuring that the power supply operates within the normal operating temperature range and preventing damage to the equipment due to overheating.

[0003] For example, the A-type emergency lighting centralized power box with application number CN202310557163.9 relates to the technical field of power boxes, including a box body, a mounting assembly is provided on the box body, a top box is installed on the upper end of the box body through the mounting assembly, a plurality of grilles are equidistantly provided on the sides of the top box, a dustproof net is installed between the inner walls of the top box, a rotating shaft is rotatably installed between the inner walls on both sides of the top box, baffles are fixedly installed on the two sides of the rotating shaft, a positioning assembly is provided on the rotating shaft, and the rotating shaft is connected to the side of the top box through the positioning assembly. The present invention slides the sleeve backward to disengage the card block from the inside of the card slot. At this time, the rotating shaft can be rotated, which will flip the baffle so that the two baffles are set above the dustproof net. The staff loosens the sleeve, and the card block can be set in the card slot through the elasticity of the spring, so that the rotating shaft can be fixed, and the two baffles can be fixed, and the device can be set to a sealed state. Most of the current cabinet doors adopt a door panel opening and closing structure such as the solution. This structure requires a deeper shell to accommodate electronic components, so as to ensure the basic function of protecting the electronic components.

[0004] Based on the search of the above patents and combined with the equipment in the prior art, it is found that the shell of the prior art is not convenient for maintenance personnel to observe and repair various components inside.

[0005] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a protective device for emergency lighting centralized power supply is provided, in order to achieve a more practical purpose. Utility Model Content

[0012] Furthermore, a magnet is fixedly connected to the side of the cover shell, and an iron block corresponding to the magnet is fixedly connected to the base plate.

[0013] Furthermore, the cover shell is fixedly connected with a handle.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model facilitates opening the two cover shells by sliding two symmetrically distributed cover shells, wherein the cover shells are provided with a slope track for pressing down the carrier plate, so that when the cover shells are closed, the carrier plate is pressed down to be in a contracted state, and the overall structure is compact.

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 4 As shown:

[0026] The utility model provides a protective device for emergency lighting centralized power supply, comprising:

[0027] A base plate 1 and two sets of parallel guide rails 42 mounted on the base plate 1, a slider 41 is slidably connected to the guide rails 42, each set of guide rails 42 is correspondingly provided with a cover shell 2, the two cover shells 2 are arranged oppositely, the cover shell 2 is provided with an opening 20, and the two openings 20 are arranged oppositely;

[0028] The telescopic member 5 has an electronic component group 6 mounted thereon. When the two housings 2 are closed, the telescopic member 5 can be retracted.

[0029] In this embodiment, two symmetrically distributed cover shells 2 are slidably arranged to facilitate opening of the two cover shells 2, wherein the cover shells 2 are provided with a slope track 21 for pressing down the carrier plate 51, so that when the cover shells 2 are closed, the carrier plate 51 is pressed down to be in a retracted state, and the overall structure is compact. When the electronic component group 6 needs to be repaired, the two cover shells 2 are opened, and the carrier plate 51 pops up under the elastic force of the spring 53, so that the carrier plate 51 and the electronic component group 6 arranged thereon extend outward, thereby facilitating maintenance personnel to observe and repair the internal electronic component group 6.

[0030] In actual implementation, it is necessary to connect the two covers 2 by providing a snap lock.

[0031] The telescopic member 5 includes a carrier plate 51 arranged parallel to the base plate 1, at least three guide rods 52 fixedly connected to the base plate 1, and a spring 53 sleeved on the guide rod 52. The carrier plate 51 is provided with a sliding hole corresponding to the guide rod 52, the guide rod 52 is slidably connected to the sliding hole, a limit block 521 is provided at the end of the guide rod 52, and the spring 53 is provided between the carrier plate 51 and the base plate 1. At least four groups of side rollers 54 are provided on the carrier plate 51, and the side rollers 54 are symmetrically distributed on the upper and lower sides of the carrier plate 51. The housing 2 is provided with a ramp track 21 corresponding to the side rollers 54. When the ramp track 21 moves inward, it squeezes the side rollers 54, so that the side rollers 54, under the action of the inclined ramp track 21, the carrier plate 51 approaches the base plate 1 along the axial direction of the guide rod 52, so that the carrier plate 51 is squeezed to a position such as Figure 1 Status shown.

[0032] The side of the cover 2 is fixedly connected with a magnet 23, and the base plate 1 is fixedly connected with an iron block 3 corresponding to the magnet 23. The setting of the iron block 3 limits the movement of the cover 2, and the matching setting of the magnet 23 and the iron block 3 temporarily fixes the cover 2, which is convenient for maintenance personnel to operate. The cover 2 will not move around, and will not interfere with the maintenance operation of the maintenance personnel.

[0033] The cover shell 2 is fixedly connected with a handle 22. The setting of the handle 22 is convenient for the operator to apply a pulling force to the cover shell 2, so as to open and close the cover shell 2.

[0034] The specific usage and function of this embodiment are as follows:

[0035] When the utility model is in use, when maintenance is needed, Figure 1 In the state shown, the operator opens the buckle lock, holds the two handles 22, and pulls the two cover shells 2 outward, so that the magnets 23 on the cover shells 2 are attracted to the iron block 3. At the same time, the side rollers 54 move outward with the outer side of the cover shell 2, so that the carrier plate 51 extends outward under the elastic force of the spring 53 and pushes the electronic component group 6 to the outermost position, thereby facilitating observation and maintenance by maintenance personnel.

[0036] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
