Description

Technical Field

[0001] The utility model relates to the field of compressor installation, in particular to a compressor fastening bolt fixing structure. Background Art

[0002] The compressor fastening bolt refers to the connection structure between the compressor and the air-conditioning shell. At present, the common installation and fixing method of the compressor fastening bolt is to weld it to the bottom plate of the air-conditioning outdoor unit. However, due to the production process, it is difficult to ensure the verticality of the screw and the bottom plate. After welding, the bolt will have different degrees of deflection, resulting in the screw of the fastening bolt being completely interfered with the internal hole of the rubber vibration damping block after the subsequent installation of the rubber vibration damping block and the compressor mounting foot. During the operation of the compressor, the high-speed rotation of the internal rotor will cause the compressor to vibrate. The vibration is transmitted to the rubber vibration damping block along the connection structure between the compressor and the air-conditioning shell. The long-term operation of the unit causes the internal hole wall of the rubber vibration damping block to be worn for a certain period of time, which will produce sharp abnormal noise. The user complaint rate is high. How to solve the problem of non-vertical installation of the compressor fastening bolt on the bottom plate of the air-conditioning outdoor unit is worth pondering.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1 , Figure 2 The compressor fastening bolt fixing structure shown in the figure comprises a fastening nut 1, a rubber vibration damping block 2, a compressor mounting foot 3, an outdoor unit mounting base plate 4 and a step bolt 5, wherein the step bolt 5 comprises a screw rod and a bolt head, the outdoor unit mounting base plate 4 is provided with a through hole penetrating the upper and lower surfaces, the screw rod of the step bolt 5 passes through the through hole from below the through hole, the screw rod passing through the through hole is sleeved with a rubber vibration damping block 2, the lower end of the rubber vibration damping block 2 contacts the upper surface of the outdoor unit mounting base plate 4, the outer peripheral surface of the rubber vibration damping block 2 is sleeved with a compressor mounting foot 3, the top of the step bolt 5 is threadedly connected with a fastening nut 1, the fastening nut 1 contacts the upper end of the rubber vibration damping block 2, and further comprises a contact plate 6, the contact plate 6 comprises a clip and a base plate, the clip is provided on the upper surface of the base plate, a slot is provided on the lower surface of the outdoor unit mounting base plate 4, the clip is detachably matched with the slot, and the upper surface of the base plate contacts the end of the bolt head away from the screw rod.

[0030] The present invention discloses the method for fixing the step bolt 5 and the outdoor unit mounting base plate 4, and the method for fixing the step bolt 5 and the outdoor unit mounting base plate 4 is as follows:

[0031] like Figure 3As shown, the card slot of the outdoor unit mounting base plate 4 is a through hole penetrating the upper and lower surfaces, and a hook is provided at the end of the clip of the contact plate 6 away from the base plate. The hook of the contact plate 6 passes through the through hole from below and engages with the upper surface of the outdoor unit mounting base plate 4. A fixing hole is provided at the lower end of the rubber vibration damping block 2, and the fixing hole completely wraps the exposed portion of the hook on the upper surface of the outdoor unit mounting base plate 4.

[0032] The card slot of the outdoor unit mounting base plate 4 can be selected as a through hole penetrating the upper and lower surfaces, and cooperate with the hook of the contact plate 6 to make the outdoor unit mounting base plate 4 and the contact plate 6 firmly engaged. Since the force point is on the upper surface of the outdoor unit mounting base plate 4, the risk of the contact plate 6 falling off is smaller.

[0033] Preferably, the bottom plate is a square flat plate, the abutment plate 6 has at least four clips, the clips are arranged on the upper surface of the bottom plate near both ends of the long side, and the number of fixing holes of the rubber vibration damping block 2 is consistent with the number of clips.

[0034] Less than four clips can also be set in this solution, but the connection strength between the contact plate 6 and the outdoor unit mounting base plate 4 is relatively weak. At least four clips are set and are set close to the corners of the base plate to ensure the connection strength between the contact plate 6 and the outdoor unit mounting base plate 4. Therefore, at least four clips should be set in this case based on comprehensive considerations.

[0035] like Figure 6 As shown, the rubber damping block 2 includes an upper damping block 21 and a lower damping block 22, the upper damping block 21 includes a first bolt hole, and the lower damping block 22 includes a second bolt hole, the first bolt hole and the second bolt hole are both adapted to and coaxial with the screw rod of the step bolt 5, a limiting groove 211 is provided at the lower part of the upper damping block 21, and a limiting ring 221 is provided at the upper end of the lower damping block 22 on the circumference of the second bolt hole, the limiting groove 211 and the limiting ring 221 are detachably matched, a guide tube 212 is provided at the lower part of the upper damping block 21, the guide tube 212 is provided on the inner circumference of the limiting groove 211, and is inserted into the second bolt hole from the end away from the limiting groove 211, the upper half of the second bolt hole is provided with a sloped inner wall whose inner diameter gradually decreases from top to bottom, the outer wall of the guide tube 212 is in contact with the sloped inner wall, and the end of the guide tube 212 away from the limiting groove 211 abuts against the screw rod of the step bolt 5.

[0036] In the present solution, in order to achieve the function of guiding the step bolt 5 by using the guide tube, it is only necessary to design the upper part of the second bolt hole so that the inner diameter gradually decreases from top to bottom, and the end of the guide tube 212 away from the limiting groove 211 can be abutted against the screw rod of the step bolt 5. In the present solution, the second bolt hole may not be provided with a sloped inner wall, but considering the loss of the guide tube material due to long-term use, and the vibration generated during the operation of the unit may cause the gap between the guide tube and the step bolt 5 to increase, and the friction force may increase and cause position deviation, it is preferred to provide a sloped inner wall, and the outer wall of the guide tube 212 is in contact with the sloped inner wall, so as to eliminate the gap while protecting the material and better achieve the guiding function.

[0037] Preferably, a limiting hole is provided in the middle of the limiting ring 221, the limiting hole is coaxial with the second bolt hole, the inner diameter of the limiting hole is larger than the outer diameter of the guide tube 212, and the lower port of the limiting hole is connected to the upper port of the sloped inner wall.
