Description

Technical Field

[0001] The invention relates to the technical field of compressors, and in particular to a compressor positioning bolt structure and a compressor. Background Art

[0002] In order to achieve the purpose of reducing the vibration of the compressor, the compressor foot pad is usually designed. The compressor foot pad is made of a material with low rigidity to alleviate the vibration energy of the compressor, and the compressor positioning bolt is designed to position the foot pad to prevent the foot pad from falling out of the compressor base under the impact of external force. The existing compressor positioning bolts are fixed to the chassis by spot welding. The main function is to prevent the compressor foot pad from falling out of the base during transportation and falling, resulting in the failure of the vibration reduction foot pad of the whole machine. After the whole machine is installed at the user's home, during the actual operation, the positioning bolt basically does not play any role, but is the main path for the vibration energy of the compressor to be transmitted to the chassis. During the operation of the compressor, the foot pad will be pushed against the positioning bolt under the action of lateral force, and the vibration energy of the compressor will be transmitted to the chassis through the positioning bolt, resulting in the failure of the vibration reduction effect of the foot pad.

[0003] In order to solve the problem of compressor vibration energy being transmitted to the chassis through the positioning bolts in the prior art, the positioning bolts and the inner holes of the foot pads are usually designed to be clearance fits, leaving room for lateral movement of the foot pads. The larger the clearance between the bolts and the inner holes of the foot pads, the more conducive it is to reducing the transmission of vibration energy, but the worse the effect on transportation and falling. The two are in a contradictory relationship. Summary of the invention

[0004] One of the purposes of the present invention is to avoid the deficiencies in the prior art and provide a compressor positioning bolt structure, which can solve the problem that the foot pad is pressed against the positioning bolt under the action of lateral force during the operation of the compressor, causing the foot pad to fail in vibration reduction, and can also solve the hidden danger of the foot pad falling off the base during transportation or falling.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A compressor positioning bolt structure is provided, including a positioning bolt, a swing structure is provided at the bottom end of the positioning bolt, a through hole is vertically opened in the swing structure, a matching hole matching the through hole is vertically opened at the bottom end of the positioning bolt, and a pull pin assembly is vertically inserted into the through hole and the matching hole from bottom to top. During the production and transportation of the product, the positioning bolt can be used to fix the compressor foot pad and the base foot, and because the pull pin assembly is inserted into the swing structure and the positioning bolt, the positioning bolt cannot rotate around the swing structure. After the product arrives at the user's home, the pull pin assembly in the positioning bolt is removed, and the positioning bolt can rotate around the swing structure. This can not only solve the problem that the foot pad is pushed against the positioning bolt under the action of lateral force during the operation of the compressor, causing the foot pad to fail in vibration reduction, but also solve the hidden danger of the foot pad falling out of the base foot during transportation and falling.

[0007] Furthermore, the swing structure includes a circular convex bulge fixed to the bottom end of the positioning bolt, and a circular groove assembly rotatably matched with the circular convex bulge. When the pull pin assembly is removed, the circular convex bulge can rotate in the circular groove assembly, and the circular convex bulge can rotate with the positioning bolt during the rotation process.

[0008] Furthermore, the rotation angle of the circular convex bump in the circular groove assembly is not more than 11° with the vertical direction. According to the test, the rotation angle of the circular convex bump in the circular groove assembly is not more than 11° with the vertical direction. After the pull pin assembly is pulled out from the positioning bolt, the rocker bar on the upper part of the positioning bolt can rotate around the axis of the positioning bolt, and the vibration-damping foot pad will hit the positioning bolt under the action of the lateral force. At this time, the positioning bolt will swing under the action of the vibration-damping foot pad (i.e., give way to the foot pad), so that the vibration energy can be best eliminated from being transmitted to the chassis through the positioning bolt.

[0009] Furthermore, the circular groove assembly includes a base and a circular groove component fixed to the base. The base is used to fix and support the circular groove component, and the circular groove component is used to position the bolt to rotate with the circular convex bump.

[0010] Furthermore, the through hole sequentially penetrates the base, the circular groove component and the circular convex bulge in a straight state. The through hole sequentially penetrates the base, the circular groove component and the circular convex bulge in a straight state, and the pull pin assembly can be inserted when the base, the circular groove component, the circular convex bulge and the positioning bolt are in a straight state, thereby ensuring the overall straightness and facilitating overall installation.

[0011] Further, the circular groove component includes a slide plate symmetrically arranged to form a circular groove, a groove is arranged at the bottom of the slide plate, a slide groove is arranged on the base to install the slide plate, and a protrusion matching the groove is arranged in the slide groove. The circular groove component includes a slide plate symmetrically arranged to form a circular groove, and a slide groove is arranged on the base. When the circular protrusion is inserted into the circular groove, the slide plate is moved to increase the distance between the two slide plates, so that the circular protrusion is easily inserted into the circular groove. At the same time, after the circular protrusion is inserted into the circular groove, the slide plate is slid again to close the two slide plates, and the protrusion in the slide groove is inserted into the groove at the bottom of the slide plate for fixing.

[0012] Furthermore, the pull pin assembly includes a pull rod and a pull ring fixed to the bottom end of the pull rod, and the shape of the pull rod is not cylindrical. The pull rod is inserted into the through hole and the matching hole, so that the positioning bolt cannot rotate around the swing structure. When needed, the pull rod is pulled out through the pull ring, so that the positioning bolt can rotate around the swing structure. The pull rod is not cylindrical, which can prevent the swing rod on the upper part of the positioning bolt from rotating relative to the slide and the base when the nut is assembled.

[0013] Furthermore, a rubber pin is fixed to the top of the pull rod, and the rubber pin is located outside the matching hole. The rubber pin is used to restrict the pull rod within the through hole and the matching hole to prevent the pull rod from falling out.

[0014] Furthermore, a through hole is provided on one side of the top end of the pull rod, and the rubber pin is inserted into the through hole, and the size of the rubber pin is larger than the size of the through hole. A through hole is provided on one side of the top end of the pull rod for fixing the rubber pin, and the size of the rubber pin is larger than the size of the through hole, so that the rubber pin is not easy to fall out of the through hole, and the pull rod is restricted in the through hole and the matching hole to prevent the pull rod from falling out. When the pull rod is pulled out through the pull ring, a shear force is generated between the pull rod and the positioning bolt, and the rubber pin is sheared under the action of the shear force, so that the pull rod can be pulled out.

[0015] Beneficial effects of the present invention: A compressor positioning bolt structure of the present invention includes a positioning bolt, a swing structure is provided at the bottom end of the positioning bolt, a through hole is vertically opened at the bottom end of the positioning bolt, a matching hole matching the through hole is vertically opened at the bottom end of the positioning bolt, and a pull pin assembly is vertically inserted into the through hole and the matching hole from bottom to top. During the production and transportation of the product, the positioning bolt can be used to fix the compressor foot pad and the base foot, and because the pull pin assembly is inserted into the swing structure and the positioning bolt, the positioning bolt cannot rotate around the swing structure. After the product arrives at the user's home, the pull pin assembly in the positioning bolt is removed, and the positioning bolt can rotate around the swing structure. This can not only solve the problem that the foot pad is pushed against the positioning bolt under the action of lateral force during the operation of the compressor, causing the foot pad to fail in vibration reduction, but also solve the hidden danger of the foot pad falling out of the base foot during transportation and falling.

[0016] The second purpose of the present invention is to avoid the shortcomings of the prior art and provide a compressor, which uses the above-mentioned compressor positioning bolt structure. During the production and transportation of the product, the positioning bolt can be used to fix the compressor foot pad and the base foot, and since the pull pin assembly is inserted into the swing structure and the positioning bolt, the positioning bolt cannot rotate around the swing structure. After the product arrives at the user's home, the pull pin assembly in the positioning bolt is removed, and the positioning bolt can rotate around the swing structure. This can not only solve the problem that the foot pad is pressed against the positioning bolt under the action of lateral force during the operation of the compressor, causing the foot pad to fail in vibration reduction, but also solve the hidden danger of the foot pad falling off from the base foot during transportation and falling.

[0025] Positioning bolt 1, swing structure 2, through hole 3, matching hole 4, pull pin assembly 5, foot pad 6, base foot 7, circular convex bump 8, circular groove assembly 9, chassis 10, base 11, slide 12, slide groove 13, protrusion 14, pull rod 15, pull ring 16, rubber pin 17. DETAILED DESCRIPTION

[0026] The present invention is further described in conjunction with the following examples.

[0027] Example 1

[0028] A compressor positioning bolt structure of this embodiment, such as Figure 1-6 As shown, it includes a positioning bolt 1, a rocking structure 2 is provided at the bottom end of the positioning bolt 1, a through hole 3 is vertically opened at the bottom end of the positioning bolt 1, a matching hole 4 matching the through hole 3 is vertically opened, and a pull pin assembly 5 is vertically inserted into the through hole 3 and the matching hole 4 from bottom to top. During the production and transportation of the product, the positioning bolt 1 can be used to fix the compressor foot pad 6 and the base foot 7, and because the pull pin assembly 5 is inserted into the rocking structure 2 and the positioning bolt 1, the positioning bolt 1 cannot rotate around the rocking structure 2. After the product arrives at the user's home, the pull pin assembly 5 in the positioning bolt 1 is removed, and the positioning bolt 1 can rotate around the rocking structure 2. This can not only solve the problem that the foot pad 6 is pushed onto the positioning bolt 1 under the action of the lateral force during the operation of the compressor, causing the foot pad 6 to fail to reduce vibration, but also solve the hidden danger of the foot pad 6 falling off from the base foot 7 during transportation and falling.

[0029] The swing structure 2 includes a circular convex bulge 8 fixed to the bottom end of the positioning bolt 1, and a circular groove assembly 9 rotatably matched with the circular convex bulge 8. When the pull pin assembly 5 is removed, the circular convex bulge 8 can rotate in the circular groove assembly 9, and the circular convex bulge 8 can rotate with the positioning bolt 1 during the rotation process.

[0030] The rotation angle of the circular convex bump 8 in the circular groove assembly 9 is 11° with the vertical direction, which can be less than 11°. According to the test, the rotation angle of the circular convex bump 8 in the circular groove assembly 9 is 11° with the vertical direction. After the pull pin assembly 5 is pulled out from the positioning bolt 1, the rocker arm on the upper part of the positioning bolt 1 can rotate around the axis of the positioning bolt 1, and the vibration-damping foot pad 6 will be pushed against the positioning bolt 1 under the action of the lateral force. At this time, the positioning bolt 1 will swing under the action of the vibration-damping foot pad 6 (i.e., give way to the foot pad), so that the vibration energy can be best eliminated from being transmitted to the chassis 10 through the positioning bolt 1.

[0031] The circular groove assembly 9 includes a base 11 and a circular groove component fixed to the base 11. The base 11 is used to fix and support the circular groove component, and the circular groove component is used to position the bolt 1 to rotate along with the circular convex bump 8.

[0032] The through hole 3 sequentially penetrates the base 11 in a straight state, the circular groove component and the circular convex bulge 8. The through hole 4 sequentially penetrates the base 11 in a straight state, the circular groove component and the circular convex bulge 8, and can insert the pull pin assembly 5 when the base 11, the circular groove component, the circular convex bulge 8 and the positioning bolt 1 are in a straight state, ensuring the overall straightness and facilitating the overall installation.

[0033] The circular groove component includes a slide 12 symmetrically arranged to form a circular groove, a groove is arranged at the bottom of the slide 12, and a slide groove 13 is arranged on the base 11 to install the slide 12, and a protrusion 14 matching the groove is arranged in the slide groove 13. The circular groove component includes a slide 12 symmetrically arranged to form a circular groove, and the base 11 is provided with a slide groove 13. When the circular convex hull 8 is installed in the circular groove, the slide 12 is moved to increase the distance between the two slides 12, so that the circular convex hull 8 is easily installed in the circular groove. At the same time, after the circular convex hull 8 is installed in the circular groove, the slide 12 is slid again to close the two slides 12, and the protrusion 14 in the slide groove 13 is inserted into the groove at the bottom of the slide 12 to be fixed.

[0034] The pull pin assembly 5 includes a pull rod 15 and a pull ring 16 fixed to the bottom end of the pull rod 15. The pull rod 15 is not cylindrical. The pull rod 16 is inserted into the through hole 3 and the matching hole 4, so that the positioning bolt 1 cannot rotate around the swing structure 2. When needed, the pull rod 15 is pulled out through the pull ring 16, so that the positioning bolt 1 can rotate around the swing structure 2. The pull rod 15 is not cylindrical, which can prevent the swing rod on the upper part of the positioning bolt 1 from rotating relative to the slide 12 and the base 11 when the nut is assembled.

[0035] A rubber pin 17 is fixed to the top of the pull rod 15, and the rubber pin 17 is located outside the matching hole 4. The rubber pin 17 is used to restrict the pull rod 15 within the through hole 3 and the matching hole 4 to prevent the pull rod 15 from falling out.

[0036] A through hole is provided at one side of the top end of the pull rod 15, and the rubber pin 17 is inserted into the through hole. The size of the rubber pin 17 is larger than the size of the through hole. A through hole is provided at one side of the top end of the pull rod 15 for fixing the rubber pin 17. At the same time, the size of the rubber pin 17 is larger than the size of the through hole. The rubber pin 17 is not easy to fall out of the through hole, and the pull rod 15 is restricted in the through hole 3 and the matching hole 4 to prevent the pull rod 15 from falling out. When the pull rod 15 is pulled out through the pull ring 16, a shear force is generated between the pull rod 15 and the positioning bolt 1, and the rubber pin 17 is sheared under the action of the shear force, so that the pull rod 15 can be pulled out.

[0037] After the compressor positioning bolt structure is integrally assembled with the compressor foot 7, the vibration-damping pad 6 and the chassis 10, the pull rod 15 in this state is located inside the positioning bolt 1 and is used to fix the positioning bolt 1. This state is used in the transportation process of the whole machine after it leaves the factory to prevent the vibration-damping pad 6 from falling out of the compressor foot 7 due to bumps or accidental falls of the whole machine during transportation. After the whole machine is installed at the user's home, the installer can pull out the pull rod 15 from the bottom of the chassis 10 through the pull ring 16. In order to prevent the pull rod 15 from accidentally falling out of the positioning bolt 1 during transportation, a rubber pin 17 is designed on the upper part of the pull rod 15. After installation at the user's home, the pull rod 15 needs to be pulled out. The installer pulls the pull ring hard, and a shear force is generated between the pull rod 15 and the positioning bolt 1. The rubber pin 17 is sheared off under the action of the shear force, so that the pull rod 15 can be pulled out, achieving Figure 5 The status shown is Figure 6 State transitions are shown.

[0038] Example 2

[0039] The present embodiment provides a compressor, which uses the compressor positioning bolt structure described in Example 1. During the production and transportation of the product, the positioning bolt 1 can be used to fix the compressor foot pad 6 and the base foot 7, and since the pull pin assembly 5 is inserted into the swing structure 2 and the positioning bolt 1, the positioning bolt 1 cannot rotate around the swing structure 2. After the product arrives at the user's home, the pull pin assembly 5 in the positioning bolt 1 is removed, and the positioning bolt 1 can rotate around the swing structure 2. This can solve the problem that the foot pad 6 is pushed against the positioning bolt 1 under the action of lateral force during the operation of the compressor, causing the vibration reduction failure of the foot pad 6, and can also solve the hidden danger of the foot pad 6 falling off from the base foot 7 during transportation and falling.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
