Description

Technical Field

[0001] This utility model belongs to the field of piston compressor technology, specifically relating to a novel protector card and piston compressor. Background Technology

[0002] In current piston compressors, the protector, as a core safety component, plays a crucial role in the normal operation and long-term stability of the equipment. Its main function is to promptly cut off the power supply when the compressor experiences overload, overheating, or abnormal current, thereby preventing motor burnout or system damage and ensuring the overall safety and reliability of the equipment. The protector clip, as a key structural component for securing the protector, is responsible for accurately, firmly, and reliably installing and fixing the protector to the designated position on the compressor housing.

[0003] Traditional installation methods rely on manual operation: the protector clip is manually pressed into the groove on the housing's protective frame, utilizing its elastic deformation to create a fixing effect. Then, the protector chassis is brought into contact with the compressor housing, aligned with the mounting guide holes on the protector clip, and a certain amount of force is applied to position the protector, ultimately securing it in place. Although this method was widely used for a period, its reliance on manual operation also brought about several problems.

[0004] First, manual installation is not only labor-intensive and inefficient, but also prone to inconsistent installation quality due to inconsistent operation. Second, the protector clip structure is relatively simple, often made of stamped metal sheets. Prolonged use under conditions of vibration and temperature changes can lead to fatigue deformation, resulting in a decrease in clamping force. If the protector clip is not securely installed or becomes loose, the protector may deviate from its intended position or even fall off completely, thus losing its protective function for the compressor and posing a serious safety hazard.

[0005] Therefore, there is an urgent need for a new type of protector card and piston compressor to solve the above problems. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing a novel protector card and piston compressor. The protector card is fixedly connected to the housing in an integrated manner, requiring no installation, and the protector can be securely contained within the protector card.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A new type of protector card includes, The circular base has an outer perimeter that is not a complete circle; a portion of it is missing, forming a notch. The area of ​​the notch is less than half the area of ​​the complete circle on which the base is located. Several claws made of elastic material are connected to the arc-shaped outer periphery of the base. The inner side of the claws is provided with guide grooves, and the shape of the guide grooves is adapted to the boss at the end of the protector. When the boss is embedded in the guide groove, the claw undergoes elastic deformation due to the elasticity of its own material and provides clamping force, thereby allowing the protector to be installed on the base.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the number of the claws is 2-3, and they are evenly distributed along the arc-shaped outer periphery of the base.

[0010] Furthermore, the guide groove is an arc-shaped groove, the curvature of which matches the outer contour of the boss.

[0011] Furthermore, the notch is one of an inwardly recessed arc-shaped notch, a polygonal groove, or a planar cut.

[0012] Furthermore, the base has a recess on the side facing the claw, and the recess is located at the center of the base.

[0013] Furthermore, the recess forms a protrusion on the other side of the base.

[0014] This utility model also provides a piston compressor, including the novel protector card described above.

[0015] Furthermore, the novel protector card is fixedly connected to the housing of the piston compressor by welding.

[0016] The beneficial effects of this utility model are: 1. In this embodiment, the base design has a coverage area greater than a semicircle, allowing for a wider enclosure of the protector and enhancing its radial constraint and installation stability. The guide groove adopts an arc-shaped design, with its curvature matching the outer contour of the boss, making the overall structure fit the shape of the protector more closely, further improving installation reliability and overall structural stability. Its notch area is smaller than a semicircle, providing ample lateral installation space while ensuring the overall structural strength and stability of the base.

[0017] 2. In this embodiment, the protector card is integrated with the housing, which not only simplifies the installation steps and saves certain labor costs, but also avoids the risk of the protector card falling off. Attached Figure Description

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0023] Example A new type of protector card, such as Figure 1 As shown, including, The circular base 1 has an outer perimeter that is not a complete circle; a portion of it is missing to form a notch 13. The area of ​​the notch 13 is less than half the area of ​​the complete circle on which the base 1 is located. Several claws 2 made of elastic material are connected to the arc-shaped outer periphery of the base 1. The inner side of the claws 2 is provided with guide grooves 21, and the shape of the guide grooves 21 is adapted to the boss 51 at the end of the protector 5. When the boss 51 is embedded in the guide groove 21, the claw 2 undergoes elastic deformation due to the elasticity of its own material and provides clamping force, thereby allowing the protector 5 to be installed on the base 1.

[0024] Specifically, there are 2-3 claws 2, which are evenly distributed along the outer periphery of the arc of the base 1.

[0025] Specifically, the guide groove 21 is an arc-shaped groove, and its curvature matches the outer contour of the boss 51.

[0026] Specifically, the notch 13 is one of an inwardly recessed arc-shaped notch, a polygonal groove, or a planar cut.

[0027] In this embodiment, the base 1 has a main body portion, the main outer contour of which is formed by an arc edge. The arc of the arc edge is less than 360 degrees, and its two ends terminate at a notch 13. The notch 13 is formed by a continuous flat surface, which connects the two ends of the arc edge, so that the overall shape of the base 1 presents a unique configuration of a circular main body larger than a semicircle combined with a planar notch 13. The area of ​​the notch 13 is smaller than that of a semicircle, providing sufficient lateral installation space while ensuring the overall structural strength and stability of the base 1.

[0028] It should be noted that, as Figure 4 As shown, the protector 5 is cylindrical, with an annular protrusion 51 at one end. The base 1 is larger than the semi-circular main body, which can cover the protector 5 over a larger area, thus providing a stable installation for the protector 5. The guide groove 21 is an arc-shaped groove, and its curvature matches the outer contour of the protrusion 51 to ensure a closer fit with the shape of the protector 5 and further ensure installation stability.

[0029] The base 1 is mounted on the piston compressor housing 4. There are three claws 2, which clamp the protector 5 at multiple angles, which is equivalent to multiple fixed directions. This prevents the protector 5 from shaking in multiple directions and helps the protector 5 to stably receive the temperature of the piston compressor housing 4.

[0030] In a preferred embodiment, the base 1 has a recess 11 on the side facing the claw 2, and the recess 11 is located at the center of the base 1.

[0031] The recess 11 forms a protrusion 12 on the other side of the base 1.

[0032] In this embodiment, the pit 11 serves as a welding point, providing a welding position for the welding head during welding.

[0033] This embodiment also provides a piston compressor, such as Figure 2-3 As shown, it includes the novel protector card 3 described above.

[0034] The novel protector card 3 is fixedly connected to the housing of the piston compressor by welding, wherein the recess 11 serves as a welding point.

[0035] In this embodiment, the integration of the protector card 3 with the housing not only simplifies the installation process and saves some labor costs, but also avoids the risk of the protector card 3 falling off.

[0036] In summary, in this embodiment, the protector clip 3 and the housing are integrally fixedly connected structures. The protector clip 3 is welded to the housing through bottom solder points, allowing the protector 5 to better receive the temperature of the housing. The structural design of the base 1 can provide a good space for the protector 5 to be placed and fitted. There is a guide groove 21 between the three claws 2 and the base 1. Because the protector 5 has a protrusion 51 at the bottom, when the protector 5 is pushed into the protector clip 3 by force, the guide groove 21 can fix the protector 5 well. When the protector 5 is pushed into the base 1 along the bottom guide groove 21 and fixed, the claws 2 are elastic and will be pushed inward and slightly flipped outward, leaving space for the protector 5 to fall completely into the base 1. Then the claws 2 will firmly lock the outer wall of the protector 5, achieving the effect of accurate positioning, easy installation, and stable non-detachment.
