Description

Technical Field

[0001] The invention relates to the technical field of lighting, and in particular to a driving power supply installation structure of a triple-proof lamp. Background Art

[0002] Tri-proof lamps are waterproof, dustproof and anti-corrosion lamps, usually used in railways, electric power, metallurgy, petroleum and petrochemical and various factories, stations and large facilities, venues and other places that require high-brightness projection lighting. There are usually two possibilities for tri-proof lamp failures. One is the failure of the driving power supply, and the other is the failure of the light bar. In the current existing structure, the driving power supply is inconvenient to disassemble and even difficult to disassemble and replace. As a result, in many cases, the tri-proof lamp that cannot be used normally due to the failure of the driving power supply can only be replaced as a whole, which makes the use cost higher. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a power supply installation structure for a three-proof lamp, which can conveniently disassemble, assemble and replace the driving power supply, thereby effectively reducing the use cost.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: A driving power supply installation structure for a three-proof lamp comprises a lamp base shell and a driving power supply, wherein the left side portion of the driving power supply extends to the left and is provided with a left connecting plate, and the right side portion of the driving power supply extends to the right and is provided with a right connecting plate, a positioning mounting seat is provided at the installation position of the lamp base shell corresponding to the left connecting plate, and a positioning shelf is provided at the position of the lamp base shell corresponding to the right connecting plate, the positioning mounting seat has a positioning slot with a right side opening, the left connecting plate is inserted into the positioning slot, a positioning buckle is provided on the positioning shelf seat, and the positioning buckle is detachably installed in the lamp base shell, and the right connecting plate is placed on the positioning shelf seat and fixed by the positioning buckle.

[0005] The positioning mounting seat includes a front limiting wall, a rear limiting wall, a support bottom plate and a lower limiting plate spaced below the support bottom plate. The front limiting wall and the rear limiting wall are vertically spaced and spaced from front to back. The tops of the front limiting wall and the rear limiting wall are connected through the support bottom plate. The left side of the lower limiting plate is connected to the support bottom plate through a connecting wall. The positioning slot is formed between the front limiting wall, the rear limiting wall, the support bottom plate, the connecting wall and the lower limiting plate. The above structure forms a stable limiting installation for the left connecting plate of the driving power supply.

[0006] The support bottom plate protrudes downward to form a left support convex part, and a left support spring sheet is arranged on the left support convex part. The left support convex part has a left hollow cavity that passes through from top to bottom at the position corresponding to the arrangement of the left support spring sheet. One end of the left support spring sheet is a fixed end that is fixedly installed in the left hollow cavity, and the other end of the left support spring sheet is a free end. When not under force, the position of the free end is lower than the position of the fixed end. After installation, the upper end face of the left connecting plate abuts against the left support spring sheet, and the lower end face of the left connecting plate abuts against the lower limit plate under the action of the left support spring sheet. The left support convex part provides corresponding space for the arrangement and activity of the left support spring sheet.

[0007] A left supporting part is provided on the left supporting protrusion protruding downward, and the right end of the left supporting protrusion is vertically bent downward to form a supporting wall. After installation, the left supporting part and the supporting wall are in contact with the corresponding position of the upper end surface of the left connecting plate. The left supporting part, the left supporting spring sheet and the supporting wall are arranged in sequence from left to right, and the part of the left connecting plate that is not in contact with the left supporting spring sheet is supported by the left supporting part and the supporting wall, so that the overall installation is more stable and the driving power supply is prevented from shaking.

[0008] The positioning mounting seat is detachably connected to the bottom shell of the lamp. A positioning column with an internal threaded hole is arranged at a corresponding position of the bottom shell of the lamp, and a mounting hole is arranged at a corresponding position of the support base plate. The matching mounting screws are passed through the mounting holes and screwed into the positioning column to realize the detachable connection and installation of the two, wherein the left supporting protrusion provides a corresponding setting space for the setting of the positioning column.

[0009] The positioning shelf seat includes a front limit plate, a rear limit plate and a bottom support plate. The front limit plate and the rear limit plate are arranged vertically and spaced from front to back. The tops of the front limit plate and the rear limit plate are connected through the bottom support plate. A shelf groove that passes through the front limit wall plate, the rear limit plate and the bottom support plate is formed. The right connecting plate is placed in the shelf groove. The above structure realizes the stable shelf installation of the right connecting plate of the driving power supply, and cooperates with the positioning buckle to realize its stable fixed installation.

[0010] The bottom support plate has a right support protrusion protruding downward, a right support spring is arranged on the right support protrusion, and a right hollow cavity is provided on the right support protrusion corresponding to the position where the right support spring is arranged, one end of the right support spring is a fixed end fixedly installed in the right hollow cavity, and the other end of the right support spring is a free end. When not under force, the position of the free end is lower than the position of the fixed end. After installation, the upper end surface of the right connecting plate abuts against the right supporting spring, and cooperates with the positioning buckle to press and fix the right connecting plate. The right support protrusion provides corresponding space for the arrangement and activity of the right supporting spring.

[0011] The bottom support plate is provided with a right support portion which is protruding downward. After installation, the right support portion abuts against the corresponding position of the upper end surface of the right connecting plate. The right support portion and the right support spring are arranged from left to right in sequence, and cooperate with the positioning buckle to achieve a more stable overall installation and prevent the driving power supply from shaking.

[0012] The positioning shelf is detachably connected to the bottom shell of the lamp. A positioning column with an internal threaded hole is arranged at a corresponding position of the bottom shell of the lamp, and a mounting hole is arranged at a corresponding position of the bottom support plate. The matching mounting screws are passed through the mounting holes and screwed into the positioning column to realize the detachable connection and installation of the two, wherein the right supporting protrusion provides a corresponding setting space for the setting of the positioning column.

[0013] The positioning buckle includes a pressing part and a mounting part. The bottom shell of the lamp is correspondingly provided with a mounting column with an internal threaded hole. The mounting part is correspondingly provided with a mounting hole. The mounting part is detachably connected and installed on the bottom shell of the lamp by means of a matching mounting screw passing through the mounting hole and screwed into the mounting column. The pressing part extends into the positioning shelf. By tightening the mounting screw, the pressing part presses and fixes the right connecting plate. The positioning buckle has a simple structure. The pressing and fixing or releasing of the right connecting plate is achieved by the tightness of the mounting screw. The structure is simple, the operation is convenient, and the cost is low.

[0014] The mounting hole is a waist-shaped hole. Firstly, it is convenient to adjust the left and right positions of the pressing part, so as to play a stable pressing installation role; secondly, when the driving power supply is not installed, the positioning buckle can be loosely installed on the bottom shell of the lamp through the mounting screw. Before installation, the rod of the mounting screw is set at the right end of the waist-shaped hole, so that the pressing part avoids the positioning shelf, so as to facilitate the installation of the driving power supply. After the right connecting plate of the driving power supply is installed, the whole is moved to the left, so that the pressing part is located below the right connecting plate, and the mounting screw is tightened. The mounting part is pressed by the head of the mounting screw, so as to drive the pressing part to be pressed on the lower end surface of the right connecting plate to fix the end of the driving power supply.

[0015] The pressing part is upwardly protruded with a pressing protrusion, and after installation, the pressing protrusion is pressed on the lower end surface of the right connecting plate. On the basis of achieving stable pressing installation, the contact area with the right connecting plate is small, reducing the pressing damage to the right connecting plate.

[0016] The top end surface of the pressing protrusion is an arc-shaped surface, which further reduces the pressing damage to the right connecting plate.

[0017] The right end of the mounting portion is vertically bent downward to form a vertical bending wall, and the end of the vertical bending wall is horizontally bent to form a horizontal bending wall. A limiting cavity is formed between the horizontal bending wall, the vertical bending wall and the mounting portion. The head of the mounting screw is located in the limiting cavity and is limited by the horizontal bending wall. A through operating hole is provided on the horizontal bending wall at the position of the cross groove of the head of the mounting screw. The bending wall is bent after the mounting screw is installed on the mounting portion, so that the mounting screw and the positioning buckle form an integral part, which prevents the mounting screw from falling off the positioning buckle and facilitates the disassembly and installation of the driving power supply.

[0018] Compared with the prior art, the advantages of the present invention are that a left connecting plate and a right connecting plate are respectively arranged on the left and right sides of the driving power supply, wherein the left connecting plate is positioned and installed by a positioning mounting seat, and the right connecting plate is pressed and fixed by a positioning shelf and a positioning buckle. The structure is simple and the disassembly and assembly are convenient. When the driving power supply of the lamp needs to be replaced due to a failure of the driving power supply of the lamp, it is only necessary to release the pressing effect of the positioning buckle on the right connecting plate, pull the entire driving power supply to the right, and make the left connecting plate detachable from the positioning slot, so as to realize the disassembly of the driving power supply, thereby realizing the disassembly and replacement of the driving power supply more conveniently, and effectively reducing the use cost of the whole lamp.
