Description

Technical Field

[0001] This invention relates to the field of refrigeration compressor technology, and in particular to a refrigeration compressor with protective functions. Background Technology

[0002] The refrigeration compressor is the core and heart of the refrigeration system. The compressor's capacity and characteristics determine the refrigeration system's capacity and characteristics. There are many types of compressors; based on their working principles, refrigeration compressors can be divided into constant displacement compressors and variable displacement compressors. For example, Chinese patent CN217539014U, published on October 4, 2022, discloses "A Refrigeration Compressor for Easy Heat Dissipation," which uses a cooling fan on the mounting base to improve heat dissipation and a shock-absorbing component between the fixed arm of the telescopic seat of the housing and the mounting base to reduce vibration.

[0003] However, the following problems exist in use: (1) For different models of refrigeration compressors, the connection position between the refrigeration compressor body and the mounting base is different, and the existing mounting base cannot meet the installation and use of different models of refrigeration compressors; (2) When the cooling fan is combined on the mounting base, the insufficient space at the bottom of the cooling fan will affect the air intake of the cooling fan, thereby affecting the heat dissipation effect. Summary of the Invention

[0004] The purpose of this invention is to provide a refrigeration compressor with protective functions. The mounting base can be adapted to different models of refrigeration compressor bodies for installation and can improve the heat dissipation effect of the cooling fan.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a refrigeration compressor with protective function, comprising a refrigeration compressor body, a mounting base, four shock-absorbing components, and a cooling fan; connecting seats with connecting holes are respectively provided on both sides of the bottom of the refrigeration compressor body; the mounting base includes four rectangularly distributed adjusting plates, two first telescopic members respectively disposed between two adjusting plates arranged along the length direction of the refrigeration compressor body, and two second telescopic members respectively disposed between two adjusting plates arranged along the width direction of the refrigeration compressor body; the four shock-absorbing components are respectively disposed on the four adjusting plates and are rectangularly distributed, each shock-absorbing component including a fixed base, a telescopic base telescopically disposed on the fixed base, and a fan disposed on the fixed base. The system includes a limiting component between the base and the telescopic base, restricting the telescopic base's extension and retraction stroke; shock-absorbing springs with their upper and lower ends respectively positioned between the telescopic base and the fixed base; a connecting shaft passing through a connecting hole at the top of the telescopic base; and a locking nut positioned at the upper end of the connecting shaft and pressed against the connecting base. Mounting brackets with mounting frames having a central section higher than the adjusting plate are slidably mounted on the two first telescopic components. A cooling fan is mounted on the upper surface of the mounting frame, and an exhaust channel extending towards the two second telescopic components is provided on the lower surface of the mounting frame. The cooling fan draws hot air from the main body of the refrigeration compressor into the exhaust channel for discharge. A guide component controlling the direction of hot air discharge is provided in the middle of the exhaust channel. A fixing mechanism is provided between the exhaust channel and the two second telescopic components.

[0006] A further configuration of the present invention is as follows: the first telescopic component includes a first telescopic tube disposed on the side of one of the adjusting plates, a first telescopic column disposed on the side of the other adjusting plate and telescopically disposed within the first telescopic tube, and a first knob bolt threadedly connected to the first telescopic tube and used to abut against the first telescopic column; the mounting bracket is provided with a first movable sleeve slidably disposed on the side of the first telescopic tube and a second movable sleeve slidably disposed on the first telescopic column on both sides; the second telescopic component includes a second telescopic tube disposed on one of the adjusting plates, a second telescopic column disposed on the side of the other adjusting plate and telescopically disposed within the second telescopic tube, and a second knob bolt threadedly connected to the second telescopic tube and used to abut against the second telescopic column.

[0007] A further feature of the present invention is that: telescopic grooves extending vertically are provided on both sides of the fixed base, the limiting member is a limiting shaft threaded onto the telescopic base after passing through the telescopic groove, and an internal hexagonal hole is provided at the end of the limiting member away from the telescopic base.

[0008] A further feature of the present invention is that: the side of the adjustment plate is provided with a connecting leg that extends downward to realize installation to the required installation position; the bottom of the adjustment plate is suspended from the required installation position; the bottom of the adjustment plate is provided with a support component for supporting the plate at the required installation position; the support component includes a threaded shaft at the bottom of the adjustment plate, a threaded sleeve threadedly connected to the threaded shaft and used for supporting the plate at the required installation position, and a rubber sleeve covering the lower end of the threaded sleeve.

[0009] A further configuration of the present invention is as follows: the top of the exhaust channel is higher than the upper surface of the adjusting plate, the bottom of the exhaust channel is lower than the lower surface of the adjusting plate, and an embedding groove is formed at the middle of both ends of the exhaust channel for embedding the second telescopic member without affecting the movement of the adjusting plate. A toothed groove is provided on the upper surface of the exhaust channel located in the embedding groove. The fixing mechanism includes a connecting piece disposed on the side of the second telescopic tube and located above the second knob bolt, a toothed block telescopically disposed on the connecting piece and used to engage with the toothed groove, and a linkage component disposed between the toothed block and the second knob bolt. When the second knob bolt is pressed against the second telescopic column, the linkage component drives the toothed block to move and engage with the toothed groove. When the second knob bolt is loosened, the linkage component drives the toothed block to move and disengage from the toothed groove.

[0010] A further configuration of the present invention is as follows: the linkage component includes a first wedge block disposed on the lower surface of the tooth block, a second wedge block sleeved on the second knob bolt and respectively cooperating with the two first wedge blocks, and limiting plates are provided on both sides of the connecting piece to restrict the rotation of the second wedge block. When the second knob bolt moves toward the direction close to the second telescopic column, the second wedge block drives the first wedge block to move so that the tooth block meshes on the tooth groove.

[0011] A further configuration of the present invention is as follows: the air guide assembly includes two side plates, an arc-shaped plate disposed between the two side plates, a rotating shaft disposed on the side plates and rotatably connected to the middle of both sides of the exhaust channel, and a locking knob threadedly connected to the side of the rotating shaft that extends out of the exhaust channel and abuts against the outside of the exhaust channel. When the air guide assembly rotates, the upper end of the arc-shaped plate may be located below one side of the mounting frame and abut against the top of the exhaust channel, and the lower end of the arc-shaped plate may be located below the other side of the mounting frame and abut against the bottom of the exhaust channel.

[0012] A further feature of the present invention is that air guide plates are respectively provided on both sides of the mounting frame near the first telescopic member, and the upper end of the air guide plates extends to the middle of both sides of the refrigeration compressor body.

[0013] In summary, the beneficial effects of this invention are:

[0014] 1. The mounting base includes four adjusting plates, two first telescopic components, and two second telescopic components. By adjusting the length of the first and second telescopic components, the position of the four adjusting plates can be adjusted, so that the four shock-absorbing components can correspond to the connection holes of the connecting seats of the refrigeration compressor body of different models. The shock-absorbing components can provide good shock absorption. At the same time, mounting brackets are set on the two first telescopic components, and the upper surface of the mounting frame of the mounting bracket is equipped with a cooling fan, which can draw away the heat around the refrigeration compressor body and discharge it through the exhaust channel. The air guide component in the exhaust channel can be selected to discharge hot air from the end with better heat dissipation effect according to the actual installation situation.

[0015] 2. The connecting feet allow the adjustable plate to be installed at a higher position relative to the desired installation location, thereby increasing the distance between the mounting frame and the desired installation location. This allows for a larger exhaust duct, improving the exhaust effect of hot air. At the same time, the support components allow the rubber sleeve to be elastically pressed against the desired installation location by rotating the threaded sleeve, thus improving the stability of the mounting base after installation.

[0016] 3. The connecting feet allow the adjusting plate to be installed at a higher position relative to the required installation location. This creates recessed grooves at the midpoint of both ends of the exhaust duct for the second telescopic component to be inserted without affecting the movement of the adjusting plate. The upper surface of the exhaust duct within these recessed grooves has toothed grooves. The fixing mechanism includes a connecting piece located on the side of the second telescopic tube and above the second knob bolt, a toothed block telescopically mounted on the connecting piece and used to engage with the toothed grooves, and a linkage component positioned between the toothed block and the second knob bolt. Thus, when the second knob bolt is tightened against the second telescopic column, the linkage component drives the toothed block to move and engage with the toothed grooves. When the second knob bolt is loosened, the linkage component drives the toothed block to move and disengage from the toothed grooves. Ultimately, when the second knob bolt of the second telescopic component is fixed, the exhaust duct can be simultaneously fixed and limited.

[0017] 4. The linkage component includes a first wedge block disposed on the lower surface of the tooth block, a second wedge block sleeved on the second knob bolt and respectively mating with the two first wedge blocks, and limiting plates on both sides of the connecting plate to restrict the rotation of the second wedge block. When the second knob bolt moves toward the direction close to the second telescopic column, the second wedge block drives the first wedge block to move so that the tooth block meshes on the tooth groove.

[0018] 5. The air guide assembly includes two side plates, an arc-shaped plate disposed between the two side plates, a rotating shaft disposed on the side plates and rotatably connected to the middle of both sides of the exhaust channel, and a locking knob threadedly connected to the side of the rotating shaft that extends out of the exhaust channel and abuts against the outside of the exhaust channel. When the air guide assembly rotates, the upper end of the arc-shaped plate can be positioned below one side of the mounting frame and abut against the top of the exhaust channel, and the lower end of the arc-shaped plate can be positioned below the other side of the mounting frame and abut against the bottom of the exhaust channel, so as to adjust the direction of hot air discharge.

[0019] 6. Air guide plates are installed on both sides of the mounting frame near the first telescopic component. The upper part of the air guide plates extends to the middle of both sides of the refrigeration compressor body, thereby improving the heat extraction effect of the cooling fan on the periphery of the refrigeration compressor body.

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1: A refrigeration compressor with protective functions, such as Figure 1 As shown, it includes a refrigeration compressor body 1, a mounting base 2, four shock-absorbing components 3, and a cooling fan 4. Connecting seats 11 with connecting holes are respectively provided on both sides of the bottom of the refrigeration compressor body 1.

[0031] like Figure 2 and Figure 3 As shown, the mounting base 2 includes four rectangularly distributed adjustment plates 21, two first telescopic members 22 respectively disposed between two adjustment plates 21 arranged along the length direction of the refrigeration compressor body 1, and two second telescopic members 23 respectively disposed between two adjustment plates 21 arranged along the width direction of the refrigeration compressor body 1. The first telescopic member 22 includes a first telescopic tube 221 disposed on the side of one of the adjustment plates 21, a first telescopic column 222 disposed on the side of the other adjustment plate 21 and telescopically disposed within the first telescopic tube 221, and a first knob bolt 223 threadedly connected to the first telescopic tube 221 and used to abut against the first telescopic column 222. The second telescopic member 23 includes a second telescopic tube 231 disposed on the side of one of the adjustment plates 21, a second telescopic column 232 disposed on the side of the other adjustment plate 21 and telescopically disposed within the second telescopic tube 231, and a second knob bolt 233 threadedly connected to the second telescopic tube 231 and used to abut against the second telescopic column 232.

[0032] like Figure 1 andFigure 2 As shown, the side of the adjustment plate 21 is provided with a connecting foot 24 that extends downward to achieve installation at the required installation position. The bottom of the adjustment plate 21 is suspended from the required installation position. The bottom of the adjustment plate 21 is provided with a support component 25 for supporting the installation at the required installation position. The support component 25 includes a threaded shaft 251 provided at the bottom of the adjustment plate 21, a threaded sleeve 252 threadedly connected to the threaded shaft 251 and used for supporting the installation at the required installation position, and a rubber sleeve 253 covering the lower end of the threaded sleeve 252.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, four shock-absorbing components 3 are respectively mounted on four adjusting plates 21 and are arranged in a rectangular pattern. Each shock-absorbing component 3 includes a fixed base 31, a telescopic base 32 telescopically mounted on the fixed base 31, a limiting member 33 positioned between the fixed base 31 and the telescopic base 32 and limiting the telescopic travel of the telescopic base 32, a shock-absorbing spring 34 with its upper and lower ends respectively positioned between the telescopic base 32 and the fixed base 31, a connecting shaft 35 positioned at the top of the telescopic base 32 and passing through a connecting hole, and a locking nut 36 positioned at the upper end of the connecting shaft 35 and abutting against the connecting base 11. The fixed base 31 has telescopic grooves 311 extending vertically on both sides. The limiting member 33 is a limiting shaft that passes through the telescopic grooves 311 and is threaded onto the telescopic base 32. The end of the limiting member 33 furthest from the telescopic base 32 has an internal hexagonal hole 331.

[0034] like Figure 2 and Figure 3 As shown, a mounting bracket 5 with a mounting frame 51 in the middle that is higher than the adjustment plate 21 is slidably mounted on the two first telescopic members 22. A cooling fan 4 is mounted on the upper surface of the mounting frame 51. An exhaust channel 6 extending at both ends toward the two second telescopic members 23 is provided on the lower surface of the mounting frame 51. The cooling fan 4 draws hot air from the main body 1 of the refrigeration compressor into the exhaust channel 6 and discharges it. A guide component 7 for controlling the direction of hot air discharge is provided in the middle of the exhaust channel 6. A fixing mechanism 8 is provided between the exhaust channel 6 and the two second telescopic members 23.

[0035] like Figure 3 , Figure 6 and Figure 7As shown, the mounting bracket 5 has a first movable sleeve 52 slidably mounted on the first telescopic tube 221 and a second movable sleeve 53 slidably mounted on the first telescopic column 222 on both sides. The top of the exhaust duct 6 is higher than the upper surface of the adjusting plate 21, and the bottom of the exhaust duct 6 is lower than the lower surface of the adjusting plate 21. The middle of both ends of the exhaust duct 6 has an embedding groove 61 for the second telescopic member 23 to be embedded in without affecting the movement of the adjusting plate 21. The upper surface of the exhaust duct 6 located in the embedding groove 61 is provided with a toothed groove 62. The fixing mechanism 8 includes a connecting piece 81 disposed on the side of the second telescopic tube 231 and above the second knob bolt 233, a toothed block 82 telescopically disposed on the connecting piece 81 and used to engage with the toothed groove 62, and a linkage component 83 disposed between the toothed block 82 and the second knob bolt 233. When the second knob bolt 233 is pressed against the second telescopic column 232, the linkage component 83 drives the toothed block 82 to move and engage with the toothed groove 62. When the second knob bolt 233 is loosened, the linkage component 83 drives the toothed block 82 to move and disengage from the toothed groove 62.

[0036] like Figure 6 As shown, the linkage component 83 includes a first wedge block 831 disposed on the lower surface of the tooth block 82, and a second wedge block 832 sleeved on the second knob bolt 233 and respectively cooperating with the two first wedge blocks 831. Limiting plates 811 are provided on both sides of the connecting piece 81 to restrict the rotation of the second wedge block 832. When the second knob bolt 233 moves toward the direction close to the second telescopic column 232, the second wedge block 832 drives the first wedge block 831 to move so that the tooth block 82 meshes on the tooth groove 62.

[0037] like Figure 3 and Figure 5 As shown, the air guide assembly 7 includes two side plates 71, an arc-shaped plate 72 disposed between the two side plates 71, a rotating shaft 73 disposed on the side plates 71 and rotatably connected to the middle of both sides of the exhaust channel 6, and a locking knob 74 threadedly connected to the rotating shaft 73 on one side of the exhaust channel 6 and pressed against the outside of the exhaust channel 6. When the air guide assembly 7 rotates, the upper end of the arc-shaped plate 72 can be located below one side of the mounting frame 51 and abut against the top of the exhaust channel 6, and the lower end of the arc-shaped plate 72 can be located below the other side of the mounting frame 51 and abut against the bottom of the exhaust channel 6.

[0038] Implementation effect: The mounting base 2 includes four adjusting plates 21, two first telescopic components 22, and two second telescopic components 23. By adjusting the length of the first telescopic components 22 and the second telescopic components 23, the position of the four adjusting plates 21 can be adjusted, so that the four shock-absorbing components 3 can correspond to the connection holes of the connecting seat 11 of the refrigeration compressor body 1 of different models of refrigeration compressors; and the setting of the shock-absorbing components 3 can play a good shock-absorbing effect; at the same time, the mounting brackets 5 are set on the two first telescopic components 22, and the upper surface of the mounting frame 51 of the mounting brackets 5 is equipped with a cooling fan 4, so that the heat around the refrigeration compressor body 1 can be extracted and discharged through the exhaust channel 6. The air guide component 7 in the exhaust channel 6 can be selected to discharge hot air from the end with better heat dissipation effect according to the actual installation situation.

[0039] The connection foot 24 allows the adjustment plate 21 to be raised relative to the required installation position after installation, thereby increasing the distance from the installation frame 51 to the required installation position. This allows the exhaust duct 6 to be set to a relatively larger size, thereby improving the exhaust effect of hot air. At the same time, the support component 25 allows the rubber sleeve 253 to be elastically pressed against the required installation position by rotating the threaded sleeve 252, thereby improving the stability of the installation base 2 after installation.

[0040] Because the connecting support 24 allows the adjusting plate 21 to be installed at a higher position relative to the required installation position, an embedding groove 61 is formed at the middle of both ends of the exhaust channel 6 for the second telescopic member 23 to be embedded without affecting the movement of the adjusting plate 21. The upper surface of the exhaust channel 6 located in the embedding groove 61 is provided with a toothed groove 62. The fixing mechanism 8 includes a connecting piece 81 located on the side of the second telescopic tube 231 and above the second knob bolt 233, a toothed block 82 telescopically disposed on the connecting piece 81 and used to engage with the toothed groove 62, and a linkage component 83 disposed between the toothed block 82 and the second knob bolt 233. Thus, when the second knob bolt 233 is pressed against the second telescopic column 232, the linkage component 83 drives the toothed block 82 to move and engage with the toothed groove 62. When the second knob bolt 233 is loosened, the linkage component 83 drives the toothed block 82 to move and disengage from the toothed groove 62. Finally, when the second knob bolt 233 of the second telescopic member 23 is fixed, the exhaust channel 6 can be fixed and limited at the same time. The linkage assembly 83 includes a first wedge block 831 disposed on the lower surface of the toothed block 82, and a second wedge block 832 sleeved on the second knob bolt 233 and respectively cooperating with the two first wedge blocks 831. Limiting plates 811 are provided on both sides of the connecting piece 81 to restrict the rotation of the second wedge block 832. When the second knob bolt 233 moves toward the direction close to the second telescopic column 232, the second wedge block 832 drives the first wedge block 831 to move so that the toothed block 82 meshes on the tooth groove 62.

[0041] The air guide assembly 7 includes two side plates 71, an arc-shaped plate 72 disposed between the two side plates 71, a rotating shaft 73 disposed on the side plates 71 and rotatably connected to the middle of both sides of the exhaust channel 6, and a locking knob 74 threadedly connected to the rotating shaft 73 on one side of the exhaust channel 6 and pressed against the outside of the exhaust channel 6. When the air guide assembly 7 rotates, the upper end of the arc-shaped plate 72 can be located below one side of the mounting frame 51 and abut against the top of the exhaust channel 6, and the lower end of the arc-shaped plate 72 can be located below the other side of the mounting frame 51 and abut against the bottom of the exhaust channel 6, so as to adjust the direction of hot air discharge.

[0042] Example 2: A refrigeration compressor with protective functions, in conjunction with Figure 8 As shown, the difference from Embodiment 1 is that: air guide plates 9 are respectively provided on both sides of the mounting frame 51 near the first telescopic member 22, and the upper end of the air guide plate 9 extends to the middle of both sides of the refrigeration compressor body 1.

[0043] Implementation effect: Air guide plates 9 are respectively provided on both sides of the mounting frame 51 near the first telescopic component 22. The upper end of the air guide plate 9 extends to the middle of both sides of the refrigeration compressor body 1, so that the air flow formed during the operation of the cooling fan 4 is closer to the refrigeration compressor body 1, thereby improving the heat removal effect of the cooling fan 4 on the periphery of the refrigeration compressor body 1.

[0044] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
