[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a grease gun nozzle, including a connector 1, one end of which is threadedly connected to a grease injection pipe 11 for conveying grease, and the end of the grease injection pipe 11 away from the connector 1 is threadedly connected to a grease injection nozzle 12 for injecting grease into machinery. A control component 2 for controlling the amount of grease dispensed is provided inside the grease injection nozzle 12. In practical use, the control component 2 allows the operator to adjust the amount of grease dispensed at any time during the grease injection process without replacing the grease injection nozzle or taking other complex measures. For example, if it is found that a certain part needs more grease during the grease injection process, the amount of grease dispensed can be increased simply by operating the control component 2. Conversely, if a certain part has a lower lubrication requirement, the amount of grease dispensed can be quickly reduced, greatly improving the convenience of the grease injection operation.

[0021] As one implementation method in this embodiment, such as Figure 2As shown, the control assembly 2 comprises a threaded hole 21 formed on the side wall of the oil filler neck 12, a drive rod 22 is inserted into the threaded hole 21, one end of the drive rod 22 is located outside the oil filler neck 12 and the end is fixedly connected with a knob 23, the other end of the drive rod 22 is located inside the oil filler neck 12 and is rotatably connected with the inner side wall of the oil filler neck 12, a valve plate 24 is fixedly sleeved on the outer wall of the drive rod 22 inside the oil filler neck 12, and the opposite sides of the valve plate 24 are provided with a clamping assembly 3 for assisting in fixing the valve plate 24. In specific use process, the knob 23 is rotated to drive the drive rod 22 to rotate, and the drive rod 22 rotates to drive the valve plate 24 to rotate, and the valve plate 24 rotates to change its posture inside the oil filler neck 12, thereby controlling the opening degree of the grease passage inside the oil filler neck 12, realizing the control of the grease export amount, when the valve plate 24 is rotated to be perpendicular to the grease flow direction, the passage is completely closed, and the grease stops exporting, when the valve plate 24 is rotated to be parallel to the grease flow direction, the passage is opened to the maximum, and the grease export amount is also the maximum. This operation mode is simple and intuitive, even if the operator without professional skills can quickly get started, and the clamping assembly 3 is mainly used for assisting in fixing the valve plate 24, preventing unnecessary shaking or displacement of the valve plate 24 under the impact of the grease flow when stopping the export of the grease.

[0022] As an embodiment in the present embodiment, as shown in Figure 4 As shown, the clamping assembly 3 comprises a mounting cavity 31 symmetrically formed on the side wall of the valve plate 24 and a clamping hole 32 symmetrically formed on the inner side wall of the oil filler neck 12, a moving plate 33 is arranged in the mounting cavity 31, a clamping rod 34 matched with the clamping hole 32 is fixedly connected to the side wall of the moving plate 33 close to the opening of the mounting cavity 31, a return spring 35 is fixedly connected to the side wall of the moving plate 33 away from the clamping rod 34, and the other end of the return spring 35 is fixed to the inner side wall of the mounting cavity 31. In specific use process, when the operator rotates the knob 23 to drive the drive rod 22 and the valve plate 24 to rotate, the clamping rod 34 on the valve plate 24 moves to the corresponding position of the clamping hole 32 on the inner side wall of the oil filler neck 12, the rebound force of the return spring 35 pushes the moving plate 33 to move to the opening of the mounting cavity 31, thereby driving the clamping rod 34 to extend out of the mounting cavity 31 and be clamped into the clamping hole 32, so as to ensure that the valve plate 24 will not be displaced due to the flow impact of the grease or slight external force interference, thereby ensuring the stability of the grease delivery.

[0023] As an embodiment in the present embodiment, as shown in Figure 4 As shown, limit sliding grooves 41 are formed on the inner walls of the opposite sides of the mounting cavity 31, limit sliding blocks 42 are slidably connected in the two limit sliding grooves 41, and the end portions of the two limit sliding blocks 42 are fixed to the outer side wall of the moving plate 33. In specific use process, the moving plate 33 can stably linearly slide in the mounting cavity 31 through the cooperation of the limit sliding blocks 42 and the limit sliding grooves 41.

[0024] As an embodiment in the present embodiment, as shown in Figure 2 The filter screen 13 is arranged in the inside of the connecting head 1 for filtering the impurities in the butter, and the filter screen 13 can effectively intercept the impurities in the butter, such as metal scraps, dust and the like, to prevent the impurities from entering the inside of the equipment and to avoid the problems of equipment abrasion and blockage caused by the impurities.

[0025] As an embodiment in the present embodiment, as shown in Figure 1 and Figure 3 The valve plate 24 is in a circular structure, and the outer wall of the valve plate 24 is attached to the inner wall of the oil injection nozzle 12. In the specific use process, when the valve plate 24 is in the position of closing the butter flow, the valve plate 24 is tightly attached to the inner wall of the oil injection nozzle 12, which can effectively prevent the butter from leaking from the contact gap between the valve plate 24 and the oil injection nozzle 12.

[0026] Working principle: in use, the rotating knob 23 drives the driving rod 22 to rotate, and the driving rod 22 drives the valve plate 24 to rotate when it rotates. The rotation of the valve plate 24 can change its posture in the oil injection nozzle 12, thereby controlling the opening degree of the butter passage in the oil injection nozzle 12 and realizing the control of the butter export amount. When the valve plate 24 is rotated to be perpendicular to the butter flow direction, the passage is completely closed, and the butter export is stopped. When the valve plate 24 is rotated to be parallel to the butter flow direction, the passage is opened to the maximum, and the butter export amount is also the maximum.

[0027] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them.
