Description

Technical Field

[0001] The utility model relates to the field of air-conditioning compressors, in particular to a modular hollow long shaft of an air-conditioning compressor. Background Art

[0002] The air conditioner compressor plays the role of compressing and driving the refrigerant in the air conditioner refrigerant circuit. The air conditioner compressor is generally installed in the outdoor unit. The air conditioner compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. The heat is dissipated into the air through the heat sink, and the refrigerant also changes from gas to liquid, and the pressure increases. The hollow long shaft is generally used to transmit the refrigerant.

[0003] The traditional hollow long shaft is slender. Due to its integrated structure and long length, it has the following problems: ① It requires relatively large processing equipment to be processed, which invisibly increases the processing difficulty and cost; ② Due to its limited hardness, it increases the difficulty of transportation and is prone to deformation during transportation; ③ When the air-conditioning compressor works on a moving object (vehicle) and encounters sudden acceleration and deceleration, the refrigerant in the hollow long shaft will impact the subsequent devices, thereby affecting the service life of the air-conditioning compressor. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a modular hollow long shaft for an air-conditioning compressor with improved strength and reduced processing difficulty.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a front mounting seat, a filling module and a rear mounting seat, the number of the filling modules is plural and they are arranged in sequence between the front mounting seat and the rear mounting seat, the front mounting seat, the filling module and the rear mounting seat are respectively coaxially provided with interconnected channels, the front of the front mounting seat and the rear of the rear mounting seat are respectively provided with flanges, the rear of the front mounting seat and the rear of each filling module are respectively provided with core tubes, the front of the rear mounting seat and the front of each filling module are respectively provided with sleeves, the outer diameter of the core tube is smaller than the front mounting seat and the filling module and a limiting step is formed at the connection, the inner diameter of the sleeve is consistent with the outer diameter of the core tube, the sleeve is sleeved on the relative core tube and a sealing ring is compressed between the end face and the limiting step, at least two clamping blocks are equidistantly provided along the circumferential direction on the outer periphery of the core tube, and the inner periphery of the sleeve and each clamping block are provided with matching clamping grooves corresponding to the clamping grooves.

[0006] By adopting the above technical solution, the hollow long shaft with an integrated structure is modularized into a front mounting seat and a rear mounting seat docked with the device, and a filling module filling the space between the front mounting seat and the rear mounting seat, thereby effectively shortening the length of the parts to be processed, that is, reducing the processing difficulty and processing cost, while increasing the strength to reduce the difficulty of transportation; when assembly is required, it is only necessary to insert the core tube into the relative sleeve until the card block and the card groove are engaged, and the sealing ring is pressed against the limit step and the end face of the sleeve during the assembly process to automatically achieve reliable sealing, making assembly more convenient. In addition, the length of the hollow long shaft can be adjusted by adjusting the number of filling modules per unit length, and a single assembly line can meet the length requirements of air-conditioning compressors of different specifications.

[0007] The utility model is further configured as follows: the clamping block is in a spherical shape.

[0008] By adopting the above technical solution, the spherical surface of the clamping block can guide the sleeve to expand when entering the sleeve until it reaches the corresponding clamping groove, making the assembly smoother.

[0009] The utility model is further configured as follows: the sleeve is provided with a guide groove extending from the clamping groove to the sleeve end surface, the guide groove cross section is an inverted V-shape, and the guide groove thickness is less than the clamping groove thickness.

[0010] By adopting the above technical solution, since the position of the card slot is in the blind spot, the guide groove can guide the card block from the end face of the sleeve to the corresponding card slot, making the assembly more accurate. At the same time, the guide groove can reduce the deformation of the sleeve when the card block enters the sleeve, that is, reduce the assembly resistance, making the assembly more labor-saving.

[0011] The utility model is further configured as follows: the filling module is provided with a reinforcement partition in the middle of the channel, and a water hole is provided in the middle of the reinforcement partition.

[0012] By adopting the above technical solution, on the one hand, the strength of the easily deformed part (middle part) of the partition is strengthened to reduce the possibility of deformation. On the other hand, the partition is strengthened to provide water holes. When encountering sudden acceleration and deceleration, part of the refrigerant will be blocked from the impact on subsequent devices, thereby ensuring the service life.

[0013] The utility model is further configured as follows: the channel is located on both sides of the reinforced partition plate and is surrounded by arc-shaped concave ramps that connect the water hole with the inner wall of the channel.

[0014] By adopting the above technical solution, when encountering rapid acceleration and deceleration, the refrigerant moving along the concave ramp will form a vortex that blocks the subsequent refrigerant from continuing to move, thereby further reducing the impact on subsequent devices and further extending the service life.

[0021] like Figure 1 — Figure 4As shown, the utility model discloses a modular hollow long shaft of an air-conditioning compressor, comprising a front mounting seat 1, a filling module 2 and a rear mounting seat 3. The number of the filling modules 2 is plural and they are sequentially arranged between the front mounting seat 1 and the rear mounting seat 3. The front mounting seat 1, the filling module 2 and the rear mounting seat 3 are respectively coaxially provided with a connected channel 4. A flange 5 is respectively provided in front of the front mounting seat 1 and behind the rear mounting seat 3. A core tube 6 is respectively provided in the rear of the front mounting seat 1 and behind each filling module 2. A sleeve 7 is respectively provided in front of the rear mounting seat 3 and in front of each filling module 2. The outer diameter of the core tube 6 is smaller than that of the front mounting seat 1 and the filling module 2 and a limiting step 8 is formed at the connection. The inner diameter of the sleeve 7 is consistent with the outer diameter of the core tube 6. The sleeve 7 is sleeved on the relative core tube 6 and a sealing ring 9 is compressed and provided between the end face and the limiting step 8. The outer periphery of the core tube 6 is equidistantly provided with a sealing ring 9 along the circumferential direction. At least two clamping blocks 61 are arranged, and the inner circumference of the sleeve 7 is provided with clamping grooves 71 corresponding to the clamping blocks 61, so that the hollow long shaft of the integral structure is modularized into a front mounting seat 1 and a rear mounting seat 3 docked with the device, and a filling module 2 filling the space between the front mounting seat 1 and the rear mounting seat 3, which effectively shortens the length of the parts required for processing, that is, reduces the processing difficulty and processing cost, and at the same time improves the strength to reduce the difficulty of transportation; when assembly is required, it is only necessary to insert the core tube 6 into the relative sleeve 7 until the clamping block 61 is clamped with the clamping groove 71, and the sealing ring 9 is pressed against the limiting step 8 and the end face of the sleeve 7 during the assembly process, automatically achieving reliable sealing, making the assembly more convenient, in addition, by adjusting the number of filling modules 2 per unit length, the length of the hollow long shaft can be adjusted, and a single assembly line can meet the length requirements of air-conditioning compressors of different specifications.

[0022] The clamping block 61 is spherical in shape. When the clamping block 61 enters the sleeve 7 , the spherical surface of the clamping block 61 can guide the sleeve 7 to expand until it reaches the corresponding clamping groove 71 , so that the assembly is smoother.

[0023] The sleeve 7 is provided with a guide groove 72 extending from the clamping groove 71 to the end face of the sleeve 7. The cross section of the guide groove 72 is an inverted V-shape. The thickness of the guide groove 72 is less than the thickness of the clamping groove 71. Since the position of the clamping groove 71 is in a blind spot, the guide groove 72 can guide the clamping block 61 from the end face of the sleeve 7 to the corresponding clamping groove 71, so that the assembly is more accurate. At the same time, the guide groove 72 can reduce the deformation of the sleeve 7 when the clamping block 61 enters the sleeve 7, that is, reduce the assembly resistance, so that the assembly is more labor-saving.

[0024] The filling module 2 is provided with a reinforced partition 21 in the middle of the channel 4, and a water hole 22 is provided in the middle of the reinforced partition 21. On the one hand, the reinforced partition 21 enhances the strength of the easily deformed part (the middle part) of the filling module 2 and reduces the possibility of deformation. On the other hand, the reinforced partition 21 is provided with a water hole 22. When encountering sudden acceleration and deceleration, it will block part of the refrigerant from impacting subsequent devices, thereby ensuring the service life.

[0025] The channel 4 is located on both sides of the reinforced partition 21 and is surrounded by an arc-shaped concave ramp 23 that connects the water hole 22 with the inner wall of the channel 4. When encountering sudden acceleration and deceleration, the refrigerant moving along the concave ramp 23 will form a vortex that blocks the subsequent refrigerant from continuing to move, thereby further reducing the impact on subsequent devices and further extending the service life.
