Description

Technical Field

[0001] This utility model relates to the field of disassembly tools, and in particular to a disassembly wrench. Background Technology

[0002] An external driver power supply is a power supply design where the power supply device is installed outside the lamp body. It is mainly used in ceiling lights, courtyard lights, high-mast lights, industrial and mining lights, street lights, and other lighting fixtures. Its advantages include convenient installation, easy maintenance and power supply replacement, effectively extending the lifespan of the lighting fixtures and reducing operation and maintenance costs.

[0003] In existing technologies, removing an external driver from the lamp body mainly relies on general-purpose tools such as wrenches and Phillips screwdrivers. However, these general-purpose tools are difficult to fit tightly against the outer surface of the driver, resulting in frequent slippage during disassembly and easy damage to the outer surface of the driver during force application, which leads to problems such as poor compatibility. Utility Model Content

[0004] The purpose of this utility model is to provide a disassembly wrench that, by setting the annular structure of the wrench head to fit tightly against the outer surface of the driving power supply, and by setting the serrated structure to engage and limit the movement with the groove on the outer surface of the driving power supply, prevents slippage during disassembly and facilitates disassembly.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] A disassembly wrench for disassembling the driving power supply of a lamp includes a wrench head and a handle at one end of the wrench head; the wrench head is configured as a ring structure, and the inner sidewall of the wrench head is provided with at least one serrated structure.

[0007] Preferably, the serrated structure includes a plurality of teeth spaced apart; a tooth groove is formed between two adjacent teeth, and the tooth groove is opened through the top and bottom of the inner sidewall of the wrench head.

[0008] Preferably, the cross-section of the tooth is trapezoidal and gradually decreases in size from top to bottom.

[0009] Preferably, the handle has grooves at the top and bottom of the middle, so that the outer periphery of the handle forms reinforcing ribs.

[0010] Preferably, the handle has a hanging hole extending through the top and bottom; the top and bottom of the hanging hole are provided with guide slopes in a circumferential direction.

[0011] Preferably, the wrench head and the handle are integrally formed and both are made of PC material.

[0012] By adopting the above solution, the beneficial effects of this utility model are:

[0013] This utility model provides a disassembly wrench. By setting the annular structure of the wrench head to fit tightly against the outer surface of the drive power supply, and by setting a serrated structure to engage and limit the movement with a groove on the outer surface of the drive power supply, slippage is prevented during disassembly, facilitating disassembly. In a preferred embodiment, the teeth of the serrated structure are set into a trapezoidal shape, making it easy to quickly and easily slip the wrench head onto the outer surface of the drive power supply. Simultaneously, by creating grooves in the handle to form reinforcing ribs, the structural strength of the handle during disassembly is increased. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0026] Reference Figures 1 to 4 As shown, this utility model provides a disassembly wrench for disassembling the driving power supply of a lamp, including a wrench head 1 and a handle 2 disposed at one end of the wrench head 1. The wrench head 1 and the handle 2 are integrally formed and both are made of PC material. The wrench head 1 is configured with a ring structure, and the inner sidewall of the wrench head 1 is provided with at least one serrated structure 3.

[0027] The serrated structure 3 includes a plurality of spaced teeth 31; a groove is formed between two adjacent teeth 31, and the groove extends through the top and bottom of the inner wall of the wrench head 1. The cross-section of each tooth 31 is trapezoidal and gradually tapers from top to bottom. In one specific embodiment, two serrated structures 3 are provided on the inner wall of the annular structure of the wrench head 1, which engage and limit the heat dissipation slots on the outer surface of the drive power supply. The trapezoidal structure of the teeth 31 makes it easier for the wrench head 1 to fit onto the outer surface of the drive power supply. The greater the downward insertion depth of the wrench head 1, the tighter the fit between the wrench head 1 and the outer surface of the drive power supply.

[0028] The handle 2 has grooves 4 at its top and bottom, forming reinforcing ribs 5 on its outer periphery. Creating grooves 4 on the handle 2 not only forms reinforcing ribs 5 on its outer periphery but also saves on material costs in manufacturing the handle.

[0029] The handle 2 has hanging holes 6 extending through its upper and lower ends, facilitating storage and management. Furthermore, the hanging holes 6 are located on the handle 2 corresponding to the groove 4. The top and bottom of the hanging holes 6 are provided with circumferential guide slopes 61, allowing for quick and easy hanging of the wrench.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the utility model and are not intended to limit the implementation of this utility model. For those skilled in the art, various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
