Description

Technical Field

[0001] The utility model relates to the field of mechanical accessories, and more specifically, to a spray head structure for lubricating oil. Background Art

[0002] Lubricating oil is grease and oil paste, which is mainly used for lubrication and protection of friction pairs. Its application range includes heavy load, low speed, swinging motion, open air, intermittent work and harsh environment. Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering.

[0003] For example, the differential rotary spray head disclosed in the authorization announcement number CN 107537703 B includes a V-shaped rotating arm, a nozzle, a dust cap, a sealing cover, a gasket, a limiting nut, a bearing shell, a bushing, an oil seal, a first sealing rubber ring, a second sealing rubber ring and a third sealing rubber ring. The limiting nut is threadedly connected to the arm body below the V-shaped rotating arm, and a gasket, a sealing cover and a dust cap are sequentially mounted on the arm body of the V-shaped rotating arm above the limiting nut from bottom to top. The inner wall of the sealing cover is provided with a second sealing rubber ring, and the outer wall is provided with a third sealing rubber ring. The inner wall of the dust cap is provided with a first sealing rubber ring.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0019] like Figures 1 to 3 As shown, the nozzle structure for lubricating oil comprises a shell 1 having a liquid supply chamber, an oil inlet 2 is opened on one side of the shell 1, and an oil outlet 3 is opened on the other side, and both the oil inlet 2 and the oil outlet 3 are connected to the liquid supply chamber.

[0020] A guide plate 15 is installed at the oil inlet 2, an external thread is installed on the outer wall of the guide plate 15, and an internal thread spirally connected to the external thread is installed on the inner wall of the oil inlet 2.

[0021] When the guide plate 15 is installed with the oil inlet 2, the guide plate 15 extends into the oil inlet 2, and the guide plate 15 is rotated so that the internal thread and the external thread are spirally fixed. When the guide plate 15 and the oil inlet 2 are disassembled, force is applied to rotate the guide plate 15, and the internal thread and the external thread are spirally separated, so that the guide plate 15 is rotated out of the oil inlet 2.

[0022] A plurality of first through holes 4 are provided on the housing 1, and the first through holes 4 are not connected to the liquid supply chamber, so that the lubricating oil will not overflow. A regulating tube 5 connected to the oil outlet 3 is installed at the oil outlet 3, and a transmission chamber is provided in the regulating tube 5. The regulating tube 5 passes through the oil outlet 3 and is placed in the liquid supply chamber. A plurality of second through holes 6 connected to the first through holes 4 are provided on the regulating tube 5, and the second through holes 6 are not connected to the transmission chamber. The first through holes 4 and the second through holes 6 are both provided in two rows.

[0023] The first through hole 4 and the second through hole 6 are connected by a locking member 10, and the locking member 10 includes a connecting rod 11, a fixing plate 12 and a fixing plate 2 13. The connecting rod 11, the fixing plate 12 and the fixing plate 2 13 each have two, and the fixing plate 12 and the fixing plate 2 13 are each provided with a blind hole 14 for the connecting rod 11 to extend into.

[0024] A first thread is installed on the inner wall of the blind hole 14, and second threads are installed on both ends of the connecting rod 11. The first thread is spirally connected to the second thread. One end of the connecting rod 11 is spirally fixed to the fixing plate 12, and the other end passes through the first through hole 4 and the second through hole 6, and is spirally fixed to the fixing plate 2 13.

[0025] A branch pipe 7 is installed at one end of the regulating pipe 5. The branch pipe 7 has a flow chamber, which is connected to the transmission chamber. An upper liquid outlet 8 is opened at one end of the branch pipe 7, and a lower liquid outlet 9 is opened at the other end. The upper liquid outlet 8 and the lower liquid outlet 9 are both connected to the flow chamber. Because the upper liquid outlet 8 and the lower liquid outlet 9 are installed, the lubricating oil can flow out through two paths.

[0026] Working principle: the lubricating oil enters from the oil inlet 2, flows through the liquid supply chamber, the oil outlet 3 and the transmission chamber in turn, and finally flows out from the upper liquid outlet 8 and the lower liquid outlet 9 respectively. Since a plurality of first through holes 4 are provided on the shell 1 and a plurality of second through holes 6 are provided on the regulating tube 5, appropriate first through holes 4 and second through holes 6 can be selected according to the distance between the contacted object and the upper liquid outlet 8 or the distance between the contacted object and the lower liquid outlet 9, and the two connecting rods 11 are passed through the first through holes 4 and the second through holes 6 in turn, the fixing plate 12 is fixed to one end of the connecting rod 11, and the fixing plate 2 13 is fixed to the other end of the connecting rod 11, and then the distance between the regulating tube 5 and the shell 1 can be adjusted by the fastener, and the lubricating oil can be sprayed to different positions.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
