Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical assembly auxiliary tools, specifically relating to an installation guide rail for an oil-free air compressor cup. Background Technology

[0002] The installation of the piston cup in an oil-free air compressor is a critical step in the maintenance process, directly affecting the sealing performance and service life of the equipment. Currently, the industry generally adopts manual installation, but because the piston cup is made of soft material and the installation accuracy requirement is high, maintenance personnel need to have rich experience to ensure that the piston cup is correctly fitted into the cylinder. Otherwise, it is easy to cause the piston cup to deform, wrinkle or even become unusable, which will affect the air compressor's air pumping efficiency and overall lifespan.

[0003] The current method of manually installing the piston cup has significant drawbacks, including excessive reliance on the repairman's experience, the piston cup's tendency to deform or wrinkle during installation, and even the inability to smoothly fit it into the cylinder. These problems not only increase the difficulty and cost of maintenance but also lead to a decline in the performance of the oil-free air compressor after repair, manifested as slow air pumping speed, poor sealing, and shortened service life. Utility Model Content

[0004] The purpose of this utility model is to provide an installation guide rail for the piston cup of an oil-free air compressor, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An installation guide rail for an oil-free air compressor cup includes an outer guide rail, an inner guide rail for positioning the cup fixedly installed on its inner side, and a handle for easy operation fixedly connected to the outer side of the outer guide rail.

[0007] As a preferred embodiment of this utility model, the outer side of the guide rail is provided with a support boss for supporting the cylinder, and the outer side of the guide rail is also fixedly installed with angular positioning points for positioning and limiting the rotation of the pressure plate groove by 90 degrees and 45 degrees.

[0008] As a preferred embodiment of this utility model, the bottom outer side of the guide rail is provided with a limiting boss to prevent overpressure, and the bottommost part of the guide rail is provided with an angled tapered guide platform to prevent it from not being smoothly fitted onto the connecting rod.

[0009] As a preferred embodiment of this utility model, the outer side of the guide rail and the outer side of the inner side of the guide rail are provided with tear-off grooves for easy disassembly.

[0010] As a preferred embodiment of this utility model, the outer side of the guide rail and the inner side of the guide rail are integrally formed by injection molding or machining.

[0011] Compared with the prior art, the beneficial effects of this utility model are: through the structural design of the guide rail with pre-installed leather cup, the problems of leather cup deformation, wrinkling and installation failure caused by manual installation are solved. Users only need to fix the guide rail with pre-installed leather cup on the connecting rod and press down the cylinder to automatically complete the installation of the leather cup. The guide rail can be easily removed through the tear groove, which significantly reduces the dependence on the experience of maintenance personnel and ensures that the leather cup is undamaged and leak-free after installation, thereby restoring the air pumping efficiency of the oil-free air compressor and extending its service life.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example

[0022] Reference Figures 1-4 This is an embodiment of the present utility model, which provides an installation guide rail for an oil-free air compressor cup, including an outer guide rail 1, an inner guide rail 2 for positioning the cup fixedly installed on its inner side, and a handle 3 for easy operation fixedly connected to the outer side of the outer guide rail 1.

[0023] By setting the outer side 1 of the guide rail, the inner side 2 of the guide rail, and the handle 3, the pre-positioning and convenient operation of the leather cup are realized, avoiding the deformation and wrinkling of the leather cup caused by uneven force during manual installation, ensuring that the leather cup can be accurately fitted into the cylinder, thereby improving the sealing performance and service life of the oil-free air compressor.

[0024] Specifically, the outer side of the guide rail 1 is provided with a support boss 4 for supporting the cylinder, and the outer side of the guide rail 1 is also fixedly installed with angular positioning points 5 for positioning and limiting the rotation of the pressure plate groove by 90 degrees and 45 degrees.

[0025] The setting of the support boss 4 and the angle positioning point 5 ensures that the cylinder remains stable during installation, preventing the diaphragm from being installed improperly due to offset or rotation, further ensuring that the diaphragm is free from deformation and wrinkles, and improving installation efficiency and the operating performance of the air compressor.

[0026] Furthermore, the bottom outer side of the guide rail 1 is provided with a limiting boss 6 to prevent overpressure, and the bottom of the guide rail 1 is provided with an angled taper guide 7 to prevent it from not being smoothly fitted onto the connecting rod.

[0027] The angled taper guide 7 provides a stable guiding function, enabling the cylinder to press down smoothly and ensuring that the piston cup is accurately installed, thereby improving the air compressor's pumping efficiency and durability.

[0028] Preferably, the outer side 1 of the guide rail and the outer side of the inner side 2 of the guide rail are provided with tear-off grooves 8 for easy disassembly.

[0029] Among them, the tear-off groove 8 design allows the guide rail to be easily separated after installation, avoiding residual parts from interfering with operation and significantly improving maintenance efficiency and equipment reliability.

[0030] Furthermore, the outer side 1 and the inner side 2 of the guide rail are integrally formed by injection molding or machining.

[0031] The one-piece molding structure enhances the overall strength and precision of the guide rail, avoids the errors of separate assembly, ensures the stability during the installation of the rubber cup, and thus extends the maintenance cycle and service life of the oil-free air compressor.

[0032] When in use, the leather cup is first pre-installed into the mounting guide rail consisting of the outer side 1 and the inner side 2 of the guide rail before leaving the factory; when the user is repairing, the guide rail with the pre-installed leather cup is directly installed on the connecting rod, and then the cylinder is sleeved on the support boss 4 of the guide rail.

[0033] When the cylinder is pressed down, the guide rail guides the cup to slide precisely into the cylinder cavity through the inclined tapered guide platform 7. At this point, the cup is installed in the cylinder. After installation, the guide rail is broken along the tear groove 8 and removed by applying force through the handle 3. This process achieves a non-destructive and precise installation of the cup. This process completely avoids the deformation problem caused by manual installation and ensures that the repaired air compressor has excellent sealing performance, efficient air pumping performance and long service life.

[0034] In summary, through the cooperative structure of the outer side 1 and the inner side 2 of the guide rail, combined with the synergistic effect of the support boss 4, the angle positioning point 5, the limiting boss 6, the oblique tapered guide platform 7, and the tearing groove 8, the precise pre-positioning and stable installation of the piston cup are achieved. This structural design effectively avoids problems such as piston cup deformation and wrinkles caused by manual installation, ensuring a perfect fit between the piston cup and the cylinder. It significantly improves the sealing performance, air pumping efficiency, and overall service life of the oil-free air compressor, while reducing maintenance difficulty and improving the reliability and consistency of installation.
