Technical Field

[0001] The utility model relates to the field of food equipment, and more specifically, to a spraying piece used for a transmission chain plate on food equipment. Background Art

[0002] In food equipment, it is usually necessary to lubricate specific parts of the equipment, such as transmission chain plates in the food industry, which require the use of lubricating oil. When using lubricating oil, it can be sprayed onto the transmission chain plates to be lubricated, mainly for lubrication, cooling, rust prevention, cleaning and other purposes.

[0003] For example, the lubricating oil filling nozzle disclosed in authorization announcement No. CN207500779U has a technical solution whose key points include an oil inlet, a nozzle body connected to the oil inlet, an oil delivery hose connected to the end of the nozzle body away from the oil inlet, and a filling needle inserted into the oil delivery hose at the end away from the nozzle body. The oil inlet, the nozzle body and the interior of the oil delivery hose are all connected, and the nozzle body extends toward the direction of the oil delivery hose with a protective tube covering the outside of the oil delivery hose.

[0004] In the above, the nozzle tube body and the oil delivery hose are integrated. With such an integrated structure, the lubricating oil can only be sprayed on components at fixed positions. When the distance of the sprayed object is far, since the nozzle tube body is fixed, the nozzle tube body cannot be adjusted to shorten the distance between the needle and the sprayed object. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a spraying member for use on a transmission chain plate of a food equipment, which can shorten the distance between a flow hole and a sprayed object by increasing the length of an inner tube.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A spraying member used for a transmission chain plate on food equipment comprises an oil delivery pipe body and a nozzle pipe, the oil delivery pipe body and the nozzle pipe are connected, a telescopic rod connected to the oil delivery pipe body is provided on the oil delivery pipe body, one end of the oil delivery pipe body is fixedly connected to the nozzle pipe, and the other end is spirally connected to the telescopic rod, the telescopic rod comprises an inner tube and an outer tube, the inner tube and the outer tube are movably sleeved together, the outer tube is internally connected, the inner tube can be pulled out or retracted in the outer tube, an annular groove is provided in the outer tube, an annular convex ring adapted to the annular groove is provided on the outer wall of the inner tube, an extrusion block is provided in the outer tube, and a clamping groove is provided on the outer wall of the inner tube so that the extrusion block can be placed in the clamping groove and connected to the clamping groove.

[0008] The utility model is further configured as follows: a plurality of oil outlet holes connected with the nozzle tube are opened on the nozzle tube, and the oil outlet holes surround the outer wall of the nozzle tube.

[0009] The utility model is further configured as follows: a placement plate is provided on the oil outlet hole, the placement plate is placed in the oil outlet hole and fixedly connected to the placement plate, and each placement plate is provided with flow holes with different diameters.

[0010] The utility model is further configured as follows: a sealing plate is provided on the circulation hole, the sealing plate and the circulation hole are detachably connected, and a connecting head extending into the circulation hole is provided on the sealing plate.

[0011] The utility model is further configured as follows: the inner tube is provided with a through cavity, the inner wall of the through cavity is provided with an internal thread, and the outer wall of the oil delivery pipe body is provided with an external thread spirally connected with the internal thread.

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

[0013] The lubricating oil passes through the outer tube, the inner tube, the oil delivery pipe body and the nozzle tube in sequence, and finally flows out from the oil outlet. When the distance to the sprayed object is relatively close, the inner tube extends into the outer tube. At this time, the distance is the length of the outer tube plus the oil delivery pipe body. When the distance to the sprayed object is relatively far, the oil delivery pipe body is held and force is applied outward to pull the inner tube out of the outer tube. Then, the distance between the flow hole and the sprayed object can be shortened by increasing the length of the inner tube. Since five oil outlet holes are installed and the placement plates in the five oil outlet holes are provided with flow holes of different diameters, lubricating oil of different areas can be sprayed on the sprayed object.

[0019] like Figure 1 to Figure 2 As shown, the spraying member used for the transmission chain plate on the food equipment includes an oil delivery pipe body 1 and a nozzle pipe 2. The oil delivery pipe body 1 and the nozzle pipe 2 are connected. The oil delivery pipe body 1 is provided with a telescopic rod 3 connected to the oil delivery pipe body 1. One end of the oil delivery pipe body 1 is integrally formed with the nozzle pipe 2, and the other end is spirally connected to the telescopic rod 3.

[0020] The telescopic rod 3 includes an inner tube 4 and an outer tube 5, which are movably connected. The outer tube 5 is connected internally, and the inner tube 4 can be pulled out or retracted in the outer tube 5. The inner tube 4 is provided with a through cavity 14, and an internal thread is installed on the inner wall of the through cavity 14. An external thread spirally connected to the internal thread is installed on the outer wall of the oil delivery pipe body 1.

[0021] When the telescopic rod 3 and the oil delivery pipe body 1 are disassembled, the oil delivery pipe body 1 is rotated, and the internal thread and the external thread are spirally separated, so that the oil delivery pipe body 1 is rotated out from the inner tube 4. When the telescopic rod 3 and the oil delivery pipe body 1 are installed, one end of the oil delivery pipe body 1 is inserted into the through cavity 14, and the oil delivery pipe body 1 is rotated. The external thread and the internal thread are spirally fixed, so that the telescopic rod 3 and the oil delivery pipe body 1 are installed and fixed.

[0022] An annular groove 6 is provided in the outer tube 5, an annular convex ring 7 is installed on the outer wall of the inner tube 4, an extrusion block 8 is installed in the outer tube 5, and a clamping groove 9 is provided on the outer wall of the inner tube 4, so that the annular convex ring 7 is placed in the annular groove 6 and connected to the annular groove 6, and the extrusion block 8 is placed in the clamping groove 9 and connected to the clamping groove 9.

[0023] When the inner tube 4 is pulled out from the outer tube 5, the annular convex ring 7 is engaged with the annular groove 6, and the extrusion block 8 is engaged with the clamping groove 9. When the inner tube 4 is placed in the outer tube 5, the inner tube 4 is first extended into the outer tube 5 so that the annular convex ring 7 is engaged and fixed with the annular groove 6, and the extrusion block 8 is engaged and fixed in the clamping groove 9.

[0024] The nozzle tube 2 is provided with five oil outlet holes 10 connected with the nozzle tube 2. The oil outlet holes 10 surround the outer wall of the nozzle tube 2.

[0025] A cover plate 13 is installed on the circulation hole 12. The cover plate 13 and the circulation hole 12 are detachably connected. A connector is installed on the cover plate 13. If the lubricating oil needs to flow out from only one circulation hole 12, the connector on the cover plate 13 can be inserted into the circulation hole 12 to bury the other four circulation holes 12. The circulation holes 12 from which the lubricating oil flows out can be selected according to the situation.

[0026] Working principle: the lubricating oil passes through the outer tube 5, the inner tube 4, the oil delivery pipe body 1 and the nozzle tube 2 in sequence, and finally flows out from the oil outlet 10. When the distance to the sprayed object is relatively close, the inner tube 4 is placed in the outer tube 5.
