Description

Technical Field

[0001] This application relates to the technical field of grease guns, and more particularly to a grease gun LED. Background Technology

[0002] Grease guns, as core tools for lubrication and maintenance of mechanical equipment, are widely used in the automotive, construction machinery, and rail transportation industries. They precisely inject grease into friction pairs such as bearings and gears using high-pressure injection, directly affecting equipment operating efficiency and service life. However, in actual operating scenarios, limited lighting conditions are common (such as inside equipment cavities, underground inspection wells, and nighttime outdoor operations), making it difficult for operators to clearly identify the location and status of the grease injection points.

[0003] Currently, most commercially available grease guns do not have integrated lighting, requiring external auxiliary light sources during operation. Some improvements use fixed LED light strips directly embedded in the gun body, which alleviates the lighting requirement to some extent, but has significant drawbacks:

[0004] Insufficient angle adaptability: The fixed light source is limited by the gun body structure and cannot be dynamically adjusted with the oiling angle. When the grease gun needs to be tilted or inserted sideways into a narrow space, the light is easily blocked by the gun head or surrounding components, forming a blind spot.

[0005] The aforementioned problems directly lead to a decrease in the accuracy of grease filling operations, resulting in potential hazards such as grease waste and lack of lubrication in critical areas. Therefore, there is an urgent need to develop a dedicated lighting system for grease guns that can dynamically adjust the illumination angle, coordinate with the grease filling path for positioning, and has high environmental adaptability, in order to improve the visibility and operational safety of grease filling under complex working conditions. Utility Model Content

[0006] To address the aforementioned technical problems, this application provides a grease gun LED that has the advantage of being able to adjust the illumination angle to meet usage requirements.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A grease gun LED includes a gun body, wherein the gun body is provided with an illumination component;

[0009] The lighting assembly includes a lamp tube containing an LED lamp core and a light-transmitting groove. The gun body has a rotating groove for the lamp tube to rotate, and a fixing member for fixing the lamp tube is provided between the lamp tube and the gun body.

[0010] The above technical solution allows users to operate the lamp tube to rotate in the rotating slot and adjust the angle of the light transmission slot to meet the illumination requirements. The lamp tube is also fixed by fasteners to prevent it from rotating under its own weight and affecting the illumination angle, thus ensuring the lighting effect.

[0011] As a preferred embodiment of this application, the fixing member includes an annular positioning protrusion disposed on one side of the rotating groove, and the lamp tube is provided with a snap-fit ​​protrusion that cooperates with the annular positioning protrusion on the side near the annular positioning protrusion. The lamp tube is provided with an elastic member for pressing the snap-fit ​​protrusion onto the annular positioning protrusion at the end away from the annular positioning protrusion.

[0012] To achieve the above technical solution, when the user rotates the lamp tube, the locking protrusion is restricted by the annular positioning protrusion, which gradually compresses the elastic element to disengage from the annular positioning protrusion, thus completing the rotation. However, after rotating to a suitable angle, the user releases the locking protrusion, and the lamp tube is pressed against the annular positioning protrusion under the action of the elastic element, thus causing the locking protrusion to engage in the annular positioning protrusion, thereby completing the fixation of the lamp tube.

[0013] As a preferred embodiment of this application, the elastic element includes a spring, a positioning sleeve for placing the spring is provided at the end of the lamp tube, a positioning post is provided on the gun body, one end of the spring is sleeved on the positioning post, and the other end is provided in the positioning sleeve, and the two ends of the spring abut against the gun body and the lamp tube respectively.

[0014] The above technical solution enables the lamp to be fixed under the action of the spring. At the same time, the spring is fixed between the positioning post and the positioning sleeve to prevent the spring from bending after repeated elastic deformation over a long period of time, which would prevent it from failing to meet the clamping requirements.

[0015] As a preferred embodiment of this application, a lampshade is provided on the light-transmitting groove.

[0016] The above technical solution is implemented to protect the LED chip.

[0017] As a preferred embodiment of this application, a heat sink is attached to the back of the LED chip.

[0018] The above technical solution is achieved by increasing the heat dissipation surface area through heat-spreading fins, thereby improving the heat dissipation effect.

[0019] As a preferred embodiment of this application, a lever is provided on the side of the light-transmitting groove.

[0020] The above technical solution is implemented to facilitate the rotation of the lamp tube, enabling it to overcome the spring force.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The user can operate the lamp tube to rotate in the rotating slot to adjust the angle of the light transmission slot to meet the illumination requirements, and fix the lamp tube with fasteners to prevent it from rotating under its own weight and affecting the illumination angle, so as to ensure the lighting effect.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses an LED for a grease gun. (See also...) Figure 1-2 The grease gun LED includes a gun body 1, and an illumination component 2 is provided on the top of the tailstock of the gun body 1.

[0032] Combination Figure 3-5 The lighting component 2 includes a lamp tube 21, within which an LED chip 22 is installed. A light-transmitting groove 23 is provided on the lamp tube 21, allowing light generated by the LED chip 22 to be emitted through the light-transmitting groove 23, thus providing illumination. The gun body 1 has a rotating groove for the lamp tube 21 to rotate. A fixing member 3 is provided between the lamp tube 21 and the gun body 1 to fix the lamp tube 21. This allows the user to operate the lamp tube 21 to rotate within the rotating groove and adjust the angle of the light-transmitting groove 23 to meet illumination requirements. The fixing member 3 secures the lamp tube 21 to prevent it from rotating under its own weight and affecting the illumination angle, thus ensuring the lighting effect.

[0033] The fixing component 3 includes an annular positioning protrusion 31 disposed on one side of the rotating groove. The lamp tube 21 is provided with a snap-fit ​​protrusion 32 that cooperates with the annular positioning protrusion 31 on the side near the annular positioning protrusion 31. The end of the lamp tube 21 away from the annular positioning protrusion 31 is provided with an elastic element for pressing the snap-fit ​​protrusion 32 onto the annular positioning protrusion 31. When the user rotates the lamp tube 21, the snap-fit ​​protrusion 32 is restricted by the annular positioning protrusion 31, thereby gradually compressing the elastic element to disengage from the annular positioning protrusion 31 and complete the rotation. However, after rotating to a suitable angle, the user releases the snap-fit ​​protrusion 32, and the lamp tube 21 is pressed against the annular positioning protrusion 31 under the action of the elastic element, thereby causing the snap-fit ​​protrusion 32 to engage in the annular positioning protrusion 31, thus completing the fixing of the lamp tube 21.

[0034] The elastic element includes a spring 33, with its two ends abutting against the gun body 1 and the lamp tube 21 respectively, thereby causing the lamp tube 21 to be rotated under the action of the spring 33. A positioning sleeve 34 is provided at the end of the lamp tube 21 for placing the spring 33. A positioning post 35 is provided on the gun body 1. One end of the spring 33 is sleeved on the positioning post 35, and the other end is placed in the positioning sleeve 34, thereby fixing the spring 33 between the positioning post 35 and the positioning sleeve 34 to prevent the spring 33 from bending after repeated elastic deformation over a long period of time, which would prevent it from failing to meet the clamping requirements. In order to facilitate the rotation of the lamp tube 21 and enable it to overcome the elastic force of the spring 33, a lever 26 is provided on the side of the light-transmitting groove 23.

[0035] A lampshade 24 is provided on the light-transmitting groove 23 to protect the LED chip 22. In order to prevent the LED chip 22 from overheating and burning out after prolonged use, a heat sink 25 is attached to the back of the LED chip 22, thereby increasing the heat dissipation surface and improving the heat dissipation effect.

[0036] The implementation principle of the grease gun LED in this application embodiment is as follows: the user can operate the lamp tube 21 to rotate in the rotating groove to adjust the angle of the light transmission groove 23 to meet the illumination requirements, and fix the lamp tube 21 with the fixing member 3 to prevent it from rotating under its own weight and affecting the illumination angle, so as to ensure the lighting effect. When the user rotates the lamp tube 21, the locking protrusion 32 is restricted by the annular positioning protrusion 31, which causes it to gradually compress the elastic member to disengage from the annular positioning protrusion 31, thereby completing the rotation. However, after rotating to the appropriate angle, the user releases the locking protrusion 32, and the lamp tube 21 is pressed against the annular positioning protrusion 31 under the action of the elastic member, so that the locking protrusion 32 is locked in the annular positioning protrusion 31, thereby completing the fixation of the lamp tube 21.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
