Description

Technical Field

[0001] This utility model relates to the field of cleaning component technology, specifically to a hydraulic press cleaning component. Background Technology

[0002] During the daily use of hydraulic presses, their surfaces and internal components are prone to accumulating dust, oil, and other impurities, requiring regular cleaning to ensure normal operation and extend their lifespan. Traditional cleaning methods may employ a single, fixed-direction water spray device, limiting the cleaning range and flexibility, and failing to meet the cleaning needs of different parts of the hydraulic press. For example, a single-direction water spray may not effectively cover and clean narrow gaps and corners of the hydraulic press; while cleaning large surfaces may require constant adjustments to the cleaning equipment's position, resulting in cumbersome and inefficient operation. Therefore, a hydraulic press cleaning component that can flexibly switch water spray directions to improve cleaning efficiency and effectiveness is needed. Utility Model Content

[0003] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a hydraulic press cleaning component that alters the spraying state.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a hydraulic press cleaning component, comprising:

[0005] The support rod has a liquid passage hole inside, which is connected to the external liquid supply device of the cleaning component;

[0006] A nozzle, which is slidably mounted on the end of the support rod along the axial direction of the support rod;

[0007] The nozzle has a liquid storage chamber inside that communicates with the liquid passage, a first water outlet at the end of the nozzle, and a second water outlet on the annular surface of the nozzle. The nozzle has at least two positions on the support rod. When it is in the first position, the nozzle can spray liquid from the first water outlet. When it is in the second position, the nozzle sprays liquid from the second water outlet.

[0008] Preferably, a guide column is fixed to the end of the support rod, and a sealing column is fixed to the guide column through a connecting rod. When the sealing column presses against the first water outlet, the liquid passage hole communicates with the second water outlet. When the side of the sealing column coincides with the second water outlet, the liquid passage hole communicates with the first water outlet.

[0009] Preferably, the diameter of the connecting rod is smaller than the diameter of the guide column and the sealing column, and an annular groove is provided between the guide column and the inner wall of the nozzle. When the sealing column presses against the first water outlet, the annular groove coincides with the first water outlet.

[0010] Preferably, the guide column has a first water injection hole in its inner circumferential direction, and the first water injection hole extends to the annular groove.

[0011] Preferably, the sealing column has a plurality of second water injection holes in its internal circumferential direction. When the sealing column is far away from the first water outlet, liquid can be discharged through the first water injection hole, the annular groove and the second water injection hole and from the first water outlet.

[0012] Preferably, there are multiple first and second water injection holes, which are evenly arranged inside the guide column and the sealing column, respectively.

[0013] Preferably, the sealing column is made of rubber with sealing function.

[0014] Preferably, an elastic body is provided on the outer side of the end of the support rod, one end of the elastic body is connected to the support rod, and the other end is pressed against the inside of the nozzle.

[0015] Preferably, the end of the support rod away from the nozzle is provided with a handle, the nozzle is connected to a pull rod, the support rod is provided with a clearance groove, and the pull rod extends through the clearance groove to the handle.

[0016] Preferably, a limiting plate is provided between the support rod and the nozzle.

[0017] The beneficial effects of this utility model are as follows:

[0018] The nozzle of this hydraulic press cleaning assembly can slide on the support rod and has at least two positions, allowing the liquid to be sprayed from either the first outlet at the end of the nozzle or the second outlet on the annular surface, depending on the cleaning needs. This enables the cleaning assembly to target different parts of the hydraulic press, such as narrow crevices and large surfaces, greatly increasing the flexibility and applicability of the cleaning process.

[0019] By incorporating components such as guide columns, connecting rods, annular grooves, a first water injection hole, and a second water injection hole, the flow path of the liquid within the nozzle is optimized. Multiple evenly spaced water injection holes ensure uniform liquid distribution within the nozzle, resulting in a more even liquid spray from the outlet and thus improving cleaning performance. The use of rubber sealing columns effectively prevents leakage between different outlets, guaranteeing the sealing performance of the cleaning components under various spray conditions.

[0027] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0028] Example 1

[0029] like Figures 1-6 As shown in the figure, in this embodiment, a hydraulic cleaning assembly is provided, including a support rod 1 and a nozzle 2.

[0030] The support rod 1 has a liquid passage hole 101 inside, which is connected to the external liquid supply device of the cleaning component.

[0031] The nozzle 2 is slidably mounted on the end of the support rod 1 along the axial direction. An external liquid supply device delivers cleaning liquid to the liquid storage chamber of the nozzle 2 through the liquid passage 101. The nozzle 2 can slide axially at the end of the support rod 1. By changing the position of the nozzle 2 on the support rod 1, the liquid can be sprayed out from different outlets (first outlet 201 or second outlet 202).

[0032] The nozzle 2 has a liquid storage chamber inside that communicates with the liquid passage 101. The nozzle 2 has a first water outlet 201 at its end and a second water outlet 202 on its annular surface. The nozzle 2 has at least two positions on the support rod 1. When it is in the first position, the nozzle 2 can spray liquid from the first water outlet 201. When it is in the second position, the nozzle 2 sprays liquid from the second water outlet 202. It can select to spray liquid from the end or the annular surface of the nozzle 2 according to the cleaning needs, which increases the flexibility and applicability of cleaning.

[0033] Example 2

[0034] like Figures 1-6 As shown, based on Embodiment 1, this embodiment provides a liquid flow method, as detailed below:

[0035] A guide column 4 is fixed to the end of the support rod 1. A sealing column 5 is fixed to the guide column 4 through the connecting rod 6. When the sealing column 5 presses against the first water outlet 201, the liquid passage 101 is connected to the second water outlet 202. When the side of the sealing column 5 coincides with the second water outlet 202, the liquid passage 101 is connected to the first water outlet 201. When the nozzle 2 slides to the point where the sealing column 5 presses against the first water outlet 201, the channel for liquid to flow out of the first water outlet 201 is blocked. The liquid can only flow to the second water outlet 202 and be sprayed out through the guide column 4 and related structures. When the side of the sealing column 5 coincides with the second water outlet 202, the second water outlet 202 is blocked, and the liquid flows from the liquid passage 101 to the first water outlet 201 and is sprayed out. By changing the position of the sealing column 5, the function of the nozzle 2 spraying liquid from different water outlets in the first and second positions is realized, further clarifying the specific structure and working method of switching the water spray direction.

[0036] The diameter of the connecting rod 6 is smaller than the diameters of the guide column 4 and the sealing column 5. An annular groove 7 is provided between the guide column 4 and the inner wall of the nozzle 2. When the sealing column 5 presses against the first water outlet 201, the annular groove 7 coincides with the first water outlet 201. Because the diameter of the connecting rod 6 is smaller than that of the guide column 4 and the sealing column 5, an annular groove 7 is formed. When the sealing column 5 presses against the first water outlet 201, the annular groove 7 coincides with the first water outlet 201, providing a specific channel and space for the flow of liquid. The setting of the annular groove 7 optimizes the flow path of liquid inside the nozzle 2, ensuring smooth flow of liquid under different spray conditions, and helping to improve the working efficiency of the cleaning components.

[0037] The guide column 4 has a first water injection hole 401 circumferentially arranged inside, extending to the annular groove 7. Liquid can flow from the liquid passage hole 101 into the annular groove 7 through the first water injection hole 401. The first water injection hole 401 provides a channel for liquid to flow from the liquid passage hole 101 to the annular groove 7, ensuring normal liquid transport inside the nozzle 2. It is one of the key structures for realizing the liquid spraying out from the first outlet 201. There are multiple first water injection holes 401 and second water injection holes 501, which are evenly arranged inside the guide column 4 and the sealing column 5, respectively, improving the uniformity of liquid distribution inside the nozzle 2, thereby making the liquid sprayed from the outlet more uniform and improving the cleaning effect.

[0038] The sealing column 5 has multiple second water injection holes 501 arranged in the inner circumference. When the sealing column 5 is far away from the first water outlet 201, the liquid can pass through the first water injection hole 401, the annular groove 7 and the second water injection hole 501 and be discharged from the first water outlet 201. The specific flow path of the liquid sprayed from the first water outlet 201 when the nozzle 2 is in the first position improves the liquid delivery and water spraying working principle of the cleaning component.

[0039] Example 3

[0040] like Figures 1-6 As shown, based on Embodiment 1 and Embodiment 2, this embodiment provides a sealing device, as detailed below:

[0041] The sealing column 5 is made of rubber with sealing function. When the rubber is pressed against the first water outlet 201, it can effectively block the liquid from flowing out of the first water outlet 201 and ensure that the liquid flows to the second water outlet 202. This ensures the sealing performance of the cleaning component under different water spray conditions, prevents liquid leakage, and improves the reliability and working efficiency of the cleaning component.

[0042] An elastic body is provided on the outer side of the end of the support rod 1. One end of the elastic body is connected to the support rod 1, and the other end presses against the inside of the nozzle 2. When the nozzle 2 slides, the elastic body undergoes elastic deformation, providing a counterforce that helps the nozzle 2 to reset and stabilize. The elastic body provides the nozzle 2 with a certain buffering and resetting function during sliding, ensuring the stability of the nozzle 2's position and facilitating the operator's adjustment of the nozzle 2's position.

[0043] A handle is provided at the end of the support rod 1 furthest from the nozzle 2. A pull rod 3 is connected to the nozzle 2. A clearance groove is provided on the support rod 1, and the pull rod 3 extends through the clearance groove to the handle. By pulling the handle, the operator moves the pull rod 3 within the clearance groove, thereby causing the nozzle 2 to slide on the support rod 1 and changing the position of the nozzle 2. This provides the operator with a convenient way to control the position of the nozzle 2, making the switching of water spray direction easier and improving the usability of the cleaning components.

[0044] A limiting plate is provided between the support rod 1 and the nozzle 2. The limiting plate restricts the sliding range of the nozzle 2 when it slides on the support rod 1, preventing it from detaching from the support rod 1. This ensures the structural integrity and stability of the cleaning assembly, avoids cleaning interruptions or equipment damage caused by the nozzle 2 detaching, and improves the reliability of the cleaning assembly.

[0045] Working principle:

[0046] An external liquid supply device delivers cleaning liquid to the liquid passage 101 inside the support rod 1. The liquid passage 101 is connected to the liquid storage chamber inside the nozzle 2, thereby introducing liquid into the nozzle 2.

[0047] When the nozzle 2 slides to the point where the sealing column 5 presses against the first outlet 201, the sealing column 5 blocks the flow of liquid from the first outlet 201. At this time, the liquid enters the guide column 4 through the liquid passage 101, and then flows to the second outlet 202 and is sprayed out through the relevant structure.

[0048] When the side of the sealing column 5 coincides with the second outlet 202, the second outlet 202 is blocked. The liquid flows from the liquid passage 101 through the first water injection hole 401 inside the guide column 4, the annular groove 7 between the guide column 4 and the inner wall of the nozzle 2, and the second water injection hole 501 inside the sealing column 5, and finally exits from the first outlet 201.

[0049] The operator pulls the handle, causing the pull rod 3 connected to the nozzle 2 to move within the clearance groove of the support rod 1. This allows the nozzle 2 to slide axially on the support rod 1, changing its position and thus switching the water spray direction. During the sliding process of the nozzle 2, the elastic body on the outer side of the end of the support rod 1 undergoes elastic deformation, providing a counterforce that helps the nozzle 2 to reset and stabilize. Simultaneously, the limiting plate between the support rod 1 and the nozzle 2 restricts the sliding range of the nozzle 2, preventing it from detaching from the support rod 1.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
