Description

Technical Field

[0001] The utility model relates to the technical field of grease nozzles, and particularly relates to an annular linear grease nozzle. Background Art

[0002] Grease is used for the friction parts of machinery to play a lubricating and sealing role, and is also used on the metal surface to play a role in filling voids and rust prevention. It is mainly prepared from mineral oil (or synthetic lubricating oil) and thickening agent. At normal temperature and in a static state, it is like a solid, can maintain its own shape without flowing, and can adhere to the metal without slipping. At high temperature or when subjected to external force exceeding a certain limit, it is like a liquid and can flow. This special fluidity of grease determines that it can be used for lubrication in parts where lubricating oil is not suitable. A grease nozzle is a device for coating grease on the target position of a workpiece. They are usually composed of components such as a nozzle body, a nozzle core, and a sealing ring, and have the characteristics of simple structure, convenient use, and corrosion resistance.

[0003] However, when most of the existing annular linear grease nozzles are not in use, it is necessary for the staff to manually close the flow valve. When the staff makes a mistake and forgets to close it, it is easy to cause grease leakage and waste. Summary of the Utility Model

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0019] As Figure 1-2 shown, a kind of annular linear grease nozzle includes a nozzle body 1 and a grease delivery pipe 2;

[0020] A movable groove 3 is provided at the center of the bottom end of the nozzle body 1. A grease outlet groove 4 communicating with the nozzle body 1 is provided near the edge of the bottom end of the nozzle body 1. The shape of the grease outlet groove 4 is annular and is located outside the nozzle body 1. A filter plate 5 is disposed around and in contact with the inner part of the nozzle body 1. A guide rod 6 is slidably disposed inside the filter plate 5. A baffle 7 is provided at the top end of the guide rod 6, and a sealing plate 8 is provided at the bottom end of the guide rod 6. The cross-section of the area enclosed by the filter plate 5 and the sealing plate 8 is an isosceles trapezoid. An insurance rod 9 is provided at the bottom of the sealing plate 8. The insurance rod 9 passes through the top of the movable groove 3, and the bottom end of the insurance rod 9 protrudes from the bottom end of the nozzle body 1. A return spring 10 is sleeved outside the guide rod 6. When the device is in use, the staff needs to press down the nozzle body 1 so that the insurance rod 9 contacts the surface of the workpiece to be coated, thereby squeezing the insurance rod 9 to move upward. The top end of the insurance rod 9 pushes the sealing plate 8 to move upward together, and the return spring 10 is squeezed and deformed and compressed. Since the cross-section of the area enclosed by the filter plate 5 and the sealing plate 8 is an isosceles trapezoid, after the sealing plate 8 moves upward, there will be a large gap between the outer edge of the sealing plate 8 and the inner wall of the nozzle body 1, so that the nozzle body 1 is communicated with the grease outlet groove 4, realizing the discharge of the lubricating grease. When the device is not in use, the extrusion force on the insurance rod 9 disappears. Under the elastic action of the return spring 10, the sealing plate 8 is reset to block the grease outlet groove 4, thus realizing the automatic closing of the device. The filter plate 5 can filter the lubricating grease to prevent the lumps in the lubricating grease from blocking the grease outlet groove 4 and ensuring the smooth discharge of the lubricating grease. The guide rod 6 limits the movement of the sealing plate 8 and ensures the stability of the sealing plate 8 during movement.

[0021] In this embodiment, specifically, an annular groove is provided on the contact surface between the movable groove 3 and the insurance rod 9, and an O-ring for sealing the insurance rod 9 is provided inside the annular groove. The annular groove provided provides an installation position for the O-ring and ensures the stability of the O-ring during use. The O-ring forms a good radial seal for the insurance rod 9, thereby ensuring the sealing performance of the insurance rod 9 during the up and down movement and preventing the lubricating grease from leaking from the contact surface between the movable groove 3 and the insurance rod 9.

[0022] In this embodiment, specifically, a sealing rubber sleeve 11 is coated on the outer edge of the sealing plate 8, and the outer side of the sealing rubber sleeve 11 is in contact with the inner wall of the nozzle body 1. By providing the sealing rubber sleeve 11, the outer edge of the sealing plate 8 can be squeezed against the inner wall of the nozzle body 1, thereby further improving the blocking effect of the sealing plate 8 and ensuring the sealing performance of the device when it is not in use.

[0023] In this embodiment, specifically, a flow valve 12 is provided on the outer side of the nozzle body 1. The flow valve 12 is located above the filter plate 5. When the device is in use, the operator can rotate the flow valve 12 in different directions to control the fat output of the device, so as to meet different requirements in actual use.

[0024] The above has described in detail an embodiment of the present invention. However, the above content is only a preferred embodiment of the present invention and should not be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
