The capacity and characteristics of the compressor determine the capacity and characteristics of the refrigeration system. In a sense, the design and matching of the refrigeration system is to reflect the capacity of the compressor. Therefore, the refrigeration industry in all countries of the world has invested a lot of energy in the research of refrigeration compressors, and new research directions and research results continue to emerge.

[0003] There is a patent application for a quick cable installation device: CN202010671292.7, which includes: "By operating the rotating wheel to rotate the linkage rod, the positive and negative threaded rods can be driven to rotate, which is conducive to the two movable seats installed on the positive and negative threaded rods to move closer or farther synchronously, and then the cable is clamped and fixed by the upper clamp and the lower clamp, and the upper connecting rod is slidably connected with the upper movable port, and the lower connecting rod is slidably connected with the lower movable port, which can avoid the twisting of the movable seat and improve the stability of the movement of the movable seat." Since this scheme is to clamp the cable to be installed by turning the rotating knob in actual use, the two clamps are used to clamp the cable to be installed by the tightening effect of the threaded connection, and the fixed area is relatively fixed.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-12 The present invention provides a technical solution: an installation structure of a motor power supply cable. The solution solves the problem that in actual use of the existing cable, the rubber skin of the cable will expand and contract due to different degrees of cold and hot weather. When the weather is hot, the skin of the cable may adhere to the inner wall of the clamping plate, which will cause the outer skin of the cable to be damaged over time, thereby affecting the transmission effect of the cable. The solution makes corresponding improvements to the above problems, including a steel frame 1, a connecting block 2 is provided on one side of the steel frame 1, and one end of the connecting block 2 is fixedly connected to the steel frame 1 The connecting block 2 includes a turning portion 21. The connecting block 2 itself is in an "L" shape. A sliding frame 3 is provided outside the turning portion 21. The sliding frame 3 is slidably connected to the turning portion 21. Cables 4 are provided on both sides of the sliding frame 3. A clamping plate 1 5 is provided outside the cable 4 to clamp its surface. A clamping plate 2 6 is provided on one side of the clamping plate 1 5 to clamp the cable 4. An anti-adhesion component 7 is provided outside the cable 4 to push the inner walls of the clamping plate 1 5 and the clamping plate 2 6 away from the outer wall of the cable 4. The sliding frame 3 is provided inside with an insertion rod 1 inserted into the sliding frame 3 and the turning portion 21. 1, a plurality of slots 12 for inserting the plug rod 11 are provided inside the transition part 21, a rod cap 9 is provided at the end of the plug rod 11, one side of the rod cap 9 is fixedly connected to the plug rod 11, a spring 10 is provided on one side of the rod cap 9, the spring 10 is located outside the plug rod 11, the two ends of the spring 10 are respectively fixedly connected to the rod cap 9 and the sliding frame 3, the end of the plug rod 11 is shaped as an arc surface, and the arc surface part of the end of the plug rod 11 contacts the surface of the transition part 21 during the sliding of the plug rod 11, and the arc surface end of the plug rod 11 is more conducive to the plug rod 11 entering the interior of the slot 12; in the process of working During the maintenance process, the rod cap 9 can be used to drive the plug rod 11 to be pulled out of the sliding frame 3 until the end of the plug rod 11 is separated from the connecting block 2. At this time, the sliding frame 3 is moved again to align the end of the plug rod 11 with another slot 12. The elastic force of the spring 10 will cause the plug rod 11 to be inserted into the inside of the slot 12. The position of the sliding frame 3 in this state has changed compared to before, so the position where the cable 4 is clamped will also be displaced, avoiding the surface adsorption of the cable 4 caused by clamping the same position of the outer wall of the cable 4 for a long time.

[0033] The anti-adhesion component 7 in this scheme includes a plurality of slide bars 71 penetrating the clamping plate 26, and a stop pad 76 is provided at one end of each slide bar 71. One side of the stop pad 76 is fixedly connected to the end of the slide bar 71. The top angle of the stop pad 76 is a beveled surface, and the inner wall of the stop pad 76 is an arc surface and fits the outer wall of the cable 4. The outer wall of the cable 4 is supported by the plurality of stop pads 76, which can enhance the ventilation effect of the surface of the cable 4 and reduce the influence of temperature on the outer wall of the cable 4. A gasket 74 is provided at the bottom, and the gasket 74 is fixedly connected to the slide bar 71. A spring 73 is provided on one side of the gasket 74. The two ends of the spring 73 are respectively fixedly connected to the gasket 74 and the fixing plate 72. A fixing plate 72 is also provided on the outside of the slide bar 71. The slide bar 71 can slide freely inside the fixing plate 72 and the clamping plate 6. An expansion body 75 is also provided on the outside of the slide bar 71. The expansion body 75 is fixedly connected to the slide bar 71, and the side of the expansion body 75 contacts the inner wall of the clamping plate 6.

[0034] The anti-adhesion component 7 inside the clamping plate 1 5 and the clamping plate 2 6 has the same effect. Taking the clamping plate 2 6 as an example, when the outdoor temperature is high, the multiple retaining pads 76 inside the clamping plate 2 6 can support the outer wall of the cable 4, so that the cable 4 will not directly contact the inner wall of the clamping plate 2 6, and increase the contact area between the surface of the cable 4 and the external flowing air, so that the ventilation effect is better and the influence of high temperature on the surface of the cable 4 is reduced. In addition, if the temperature continues to rise, the expansion body 75 located on the inner wall of the clamping plate 2 6 will expand before the skin of the cable 4 The continuously expanding expansion body 75 will resist the clamping plate 2 6 and push it away from the surface of the cable 4, and the other end of the expansion body 75 can also resist the resistance pad 76 to increase the stabilizing effect of the resistance pad 76 on the clamping of the cable 4; using the anti-adhesion component 7, the clamping plate 1 5 and the clamping plate 2 6 can be automatically kept away from the surface of the cable 4 in a high temperature environment, reducing the contact area between the surface of the cable 4 and the inner wall of the clamping plate, reducing the possibility of damage to the cable 4 due to surface adsorption, which is beneficial to ensure that the cable 4 has an efficient transmission effect.

[0035] Furthermore, the clamping plate 1 5 and the clamping plate 2 6 are both located above the sliding frame 3, and a limiting assembly 8 for limiting the sliding of the clamping plate 1 5 and the clamping plate 2 6 is provided inside the sliding frame 3, and the limiting assembly 8 includes a curved rod 85, and the curved rod 85 is shaped like an "L", and one end of the curved rod 85 is fixedly connected to the clamping plate 2 6, and one side of the curved rod 85 is provided with a fixed shaft 82 inserted into the sliding frame 3, and one end of the fixed shaft 82 is fixedly connected to the curved rod 85, and the interior of the sliding frame 3 is provided with a sliding groove 81 for the fixed shaft 82 to slide, and the outside of the fixed shaft 82 is provided with a rotating plate 83, and the rotating plate 83 is rotatably connected to the fixed shaft 82, and one side of the sliding frame 3 is provided with a fixed column 84, and one end of the fixed column 84 is fixedly connected to the sliding frame 3, and the rotating plate 83 includes The protrusion 831 has an end portion shaped as an arc surface, and a semicircular groove 841 which matches the protrusion 831 is provided inside the fixing column 84. The arc surface of the protrusion 831 matches the semicircular groove 841, which can further improve the stability of the clamping effect of the clamping plate 1 5 and the clamping plate 2 6 on the cable 4. The fixing shaft 82 can be slid inside the slide groove 81, so that the clamping plate 1 5 and the clamping plate 2 6 at one end of the curved rod 85 can be brought close to each other. When the rotating plate 83 is rotated until the protrusion 831 at one end is located inside the semicircular groove 841 of the fixing column 84, the retaining pad 76 inside the clamping plate 1 5 and the clamping plate 2 6 will be in the best clamping state, and the surface of the cable 4 can be clamped and fixed in multiple directions, thereby improving the stability of the clamping.

[0036] In addition, the fixing plate 72 in the present embodiment includes a groove 721, an inclined block 16 is provided inside the groove 721, one side of the inclined block 16 is fixedly connected to the fixing plate 72, a top rod 17 is provided on one side of the inclined block 16, one end of the top rod 17 is in contact with the inclined surface of the inclined block 16, a fixing rod 18 is provided at one end of the top rod 17 and is fixedly connected thereto, one end of the fixing rod 18 is fixedly connected to the turning portion 21, a notch 19 is provided inside the clamping plate 26 for the sliding rod 71 to slide, and the bottom of the gasket 74 is in contact with the notch 19. The tops are in contact with each other, a limit block 13 is provided on the outer wall of the clamping plate 2 6, and the side of the limit block 13 abuts against the arc surface of the gasket 74, and the limit block 13 includes a limit bar 131 located on its bottom surface, and the inside of the clamping plate 2 6 is provided with a limit groove 14 and a limit groove 2 15 for inserting the limit bar 131, and the limit bar 131 slides freely inside the limit groove 14 and the limit groove 2 15, and after the limit bar 131 is inserted into the limit groove 2 15, the side of the limit block 13 and the arc surface of the gasket 74 contact each other;

[0037] When the limit strip 131 is inserted into the limit groove 14, the side of the gasket 74 located outside the slide bar 71 resists against the limit block 13, thereby preventing the slide bar 71 from sliding inside the slot 19. When the maintenance personnel perform maintenance work, they can first pull the limit block 13 outward, and then move the slide frame 3 by pulling out the insertion rod 11. In this process, the top rod 17 will resist against the inclined surface of the inclined block 16, and then under the action of the inclined surface, the inclined block 16, the fixing plate 72 and the slide bar 71 are driven to the other end of the slot 19. When the slide bar 71 abuts against the other end of the slot 19, the staff can insert the limit strip 131 of the limit block 13 into the interior of the limit slot 15, so that the limit block 13 and the other side of the gasket 74 can be abutted, thereby once again ensuring the stability of the slide bar 71 inside the slot 19; at the same time, the abutment pad 76 at the end of the slide bar 71 in this state has changed the clamping position compared with before, thereby avoiding long-term clamping of a local area on the surface of the cable 4, and also solving the problem of clamping in the unidirectional area, which is beneficial to the daily maintenance of the cable 4.
