The utility model discloses convenient operation has improved work efficiency, has solved among the prior art with bolt fastening spring and fixing device operation difficulty, wastes time and energy and the problem that work efficiency is low.

In order to ensure that the card member 3 can be clamped in the first opening 21 without falling off, in one embodiment, one end of the card member 3 away from the compressor 10 is set as a head end, and the other end opposite to the head end is a tail end, where the width direction of the projection 22 refers to the same or parallel direction with the contact direction of the projection 22 and the suspension part 2, specifically, as shown in fig. 2, the minimum width of the projection 22 can be represented as b ₁ The maximum width of the projection 22 is denoted by b ₂ In order to ensure that the clamping piece 3 can be clamped in the first opening 21 without falling off when the compressor 10 is suspended, the width of the head end of the clamping piece 3 is larger than that of the tail end thereof, and meanwhile, the width of the head end of the clamping piece 3 is larger than the minimum width b of the bulge 22 ₁ Is smaller than the maximum width b of the projection 22 ₂ In order to ensure easy insertion, the width of the rearmost end of the free end of the projecting portion 22 is smaller than the maximum width of the head end of the card member 3.

In order to enable the clip 3 to be placed in the first opening 21 and suspend the compressor 10, as shown in fig. 3A and 3B, the thickness d of the clip 3 is smaller than the minimum distance h from the extreme end of the suspended end of the boss 22 to the inner side wall of the first opening 21 corresponding to the extreme end, where the extreme end of the suspended end of the boss 22 refers to the end on the boss 22 corresponding to the contact side of the suspended portion 2 and the boss 22.

In order to facilitate suspension and fixation of the compressor 10, in one embodiment, at least a portion of the extension direction of the suspended end of the protrusion 22 is an inner side wall of the first opening 21 facing the compressor 10. For example, as shown in fig. 4 to 6, the dotted line in the drawings indicates a connection line of the position of the first opening 21 relative to the compressor 10, and is only for convenience of indicating the positional relationship, and is not a true line, when the compressor 10 is in a suspended state, the suspended end of the protrusion 22 in the front view of the suspension portion 2 is disposed downward or obliquely downward toward the first opening 21, and the elastic component 1 pulls the compressor 10 obliquely downward (as shown in fig. 4 and 6), or when the suspended end of the protrusion 22 is disposed upward or obliquely upward toward the first opening 21, and the elastic component 1 pulls the compressor 10 obliquely upward (as shown in fig. 6), the directional component of the extending direction of the suspended end of the protrusion 22 is toward the inner side wall of the first opening 21 on the side close to the compressor 10 where it is located. In this case, the arrangement of the protruding portion 22 includes many possibilities, and, as shown in fig. 5A, the free end of the protruding portion 22 is located in the plane of the first opening 21; alternatively, as shown in fig. 5B, the free end of the protruding portion 22 is not in the plane of the first opening 21, and is located on the side of the suspending portion 2 away from the compressor 10 where the first opening 21 is located.

The structure of the clamping piece 3 can be various, and can be a hollow ring structure or a solid structure. When the clip 3 is a hollow ring structure, in an embodiment, as shown in fig. 13, when the compressor 10 is in a suspended state, the clip 3 can be sleeved on the boss 22, and since it is clamped on the first opening 21, the clip 3 is disposed across the suspended end of the boss 22; in another embodiment (not shown in the figures), when the clip 3 is a solid structure, if the clip 3 is a solid sheet structure and a hook is disposed on a side of the clip 3 close to the first opening 21 for preventing the compressor 10 from being suspended, the clip 3 is separated from the first opening 21, and the compressor 10 cannot be fixed, because the clip 3 and the protrusion 22 are both solid structures, the clip 3 can be fixed with the first opening 21 or the protrusion 22 through the hook disposed thereon, so that when the compressor 10 is in a suspended state, at least a part of the extension direction of the plane where the clip 3 is located intersects with the extension direction of the plane where the suspended end of the protrusion 22 is located.

In order to better realize the suspension of the compressor, the clip 3 may be configured in a ring structure, so as to be sleeved on the boss 22, so that the fixation is firmer. Of course, the ring structure may be a square ring structure, or may be a ring structure having another shape such as a triangle, a circle, or an ellipse. The annular structure of the clip 3 facilitates the restriction of the protrusion 22 and the first opening 21 on the clip 3, and facilitates the fixing and suspending of the compressor 10. In some embodiments, the inner diameter of the clip 3 is slightly larger than the width of the protrusion 22, so that the suspension of the compressor 10 can be realized when the clip 3 is sleeved on the protrusion 22, and when the elastic component 1 is pulled to the compressor 10 obliquely upwards or obliquely downwards, the clip 3 cannot be separated from the first opening 21, so that at least part of the gap of the protrusion 22 is sleeved in the annular structure of the clip 3, and only when the annular structure of the clip 3 is approximately perpendicular to the suspension part 2, the clip 3 can be taken out from the first opening 21, so that the installation is convenient, the clip cannot be separated due to the vibration of the compressor 10, and the fixing effect is good; or, in some embodiments, the inner diameter of the clip 3 is greater than the width of the protrusion 22, and when the clip 3 is matched with the first opening 21 to achieve suspension of the compressor 10, the clip 3 surrounds the suspended end of the protrusion 22 and needs to abut against the side wall of the first opening 21 and the suspended end of the protrusion 22 to achieve suspension of the compressor 10, that is, the clip 3 at least partially surrounds the periphery of the non-end portion of the suspended end of the protrusion 22 and abuts against the outer edge of the first opening 21 and the suspended end at the same time, and similarly, when the elastic component 1 obliquely pulls the compressor 10 to suspend the compressor, the clip 3 is clamped in the first opening 21 and cannot be separated due to vibration of the compressor 10, and only when the annular structure of the clip 3 is approximately perpendicular to the suspension portion 2, the clip 3 can be taken out from the first opening 21, which is convenient for installation and is firmly fixed.

Further, in order to facilitate the matching of the clamping piece 3 and the elastic component 1, in one embodiment, the clamping piece 3 can be a circular or oval buckle, because the vibration of the compressor 10 is multidirectional and multi-angle, and different forces are applied, so that the positions of the elastic component 1 and the clamping piece 3 cannot be accurately set, the clamping piece 3 is set to be a circular or oval buckle, when the clamping piece is set around the suspended end of the bulge 22, the clamping piece 3 can vibrate along with the compressor 10, under the condition that the elastic component 1 randomly shakes, the rotation of a certain amplitude is realized, and the movement of the clamping piece is enabled to be more free.

In order to extend the service life of the elastic member 1, and save costs, facilitate mass production, and facilitate assembly by workers, the elastic member 1 may be a tension spring, and the elastic modulus thereof may be 40 g/mm. The extension spring has large elasticity, can be produced in batches and is convenient to assemble, and the selection of the extension spring is more suitable.

In order to prolong the service life of the elastic component 1, in one embodiment, at least part of the plane of the annular structure of the clip 3 is parallel to the length direction of the elastic component 1, for example, as shown in fig. 7, when the force direction of the contact point of the clip 3 and the elastic component 1 is parallel to the elastic direction of the elastic component 1, the utilization rate of the force can be maximized, and the force is best applied, which is beneficial to prolonging the service life of the elastic component 1. In a specific embodiment, the elastic component 1 and the clamping piece 3 can be integrally formed, can be produced in batches, is convenient for workers to assemble, has relatively low cost, and can improve the working efficiency.

In order to suspend and fix the compressor 10, in one embodiment, as shown in fig. 8 to 10, the dotted lines in the drawing indicate the positional connection of the first opening 21 with respect to the compressor 10, and are for convenience of indicating the positional relationship, and are not true lines, when the compressor 10 is in a suspended state and the suspension part 2 is in a front view, the suspended end where the protrusion 22 exists is disposed upward or obliquely upward toward the first opening 21, and the elastic member 1 pulls the compressor 10 obliquely downward (fig. 8, 10), alternatively, in the case where the free end of the projection 22 is disposed downward or obliquely downward toward the first opening 21, and the elastic member 1 is pulled obliquely upward toward the compressor 10 (fig. 10), at least part of the extension direction of the suspended end of the protruding portion 22 is the inner side wall of the first opening 21 away from the side close to the compressor 10. There are also many cases where the protruding portion 22 is provided, as shown in fig. 9A, the free end of the protruding portion 22 is located in the plane of the first opening 21; alternatively, as shown in fig. 9B, the free end of the boss 22 is located on the side of the suspension portion 2 of the first opening 21 away from the compressor 10.

Further, fastener 3 can set up to annular structure, through putting the annular structure card of fastener 3 in first opening 21, when realizing compressor 10 suspension, through the restriction of the bellying 22 of cover on fastener 3, avoid fastener 3 to deviate from in first opening 21, only when the annular structure of fastener 3 is close perpendicular with linkage 2, just can take out fastener 3 from first opening 21 in, when compressor 10 is suspended, elastic component 1 need incline upwards or incline and hold compressor 10 downwards, make fastener 3 and linkage 2 be in the tilt state, no matter how compressor 10 shakes, can't make fastener 3 break away from in first opening 21, and is more convenient to operate, and is fixed also more firm. In some embodiments, the inside diameter of the clip member 3 is slightly larger than the width of the protrusion 22, when the clip member 3 is sleeved on the protrusion 22, the clip member 3 can be clamped on the protrusion 22, the protrusion 22 limits the clip member 3 from coming out of the first opening 21, so that the protrusion 22 is at least partially sleeved in the annular structure of the clip member 3, and the annular structure can be a square ring, a triangular ring, a circular ring, an oval ring, or the like. In another embodiment, the inner diameter of the clip 3 is slightly larger, and the clip needs to be sleeved on the protrusion 22 and simultaneously clips the inner side wall of the first opening 21 and the suspended end of the protrusion 22, so that the suspension of the compressor 10 can be realized in a matching manner, that is, when the clip 3 is matched with the first opening 21 to realize the suspension of the compressor 10, the clip 3 at least partially surrounds the periphery of the non-end part of the suspended end of the protrusion 22 and simultaneously abuts against the outer edge of the first opening 21 and the suspended end, at this time, the annular structure of the clip 3 needs to be sleeved on the protrusion 22 and simultaneously contacts with the side wall of the first opening 21 and the suspended end of the protrusion 22.

In order to prolong the service life of the suspension part 2, in one embodiment, the suspension part 2 may be made of a metal material, and the metal material has good stability and long service life. Further, the protruding portion 22 can be integrally formed with the suspension portion 2 (as shown in fig. 6 and 10), so that the manufacturing is convenient, the assembly of the compressor assembly is convenient, and the working efficiency is improved.

In order to reduce the transmission of vibration and noise of the compressor assembly, sound insulation assemblies are further disposed around and at the bottom of the compressor 10 to reduce noise and shock. The acoustic assembly may comprise the suspension 2, i.e. the suspension 2 may be part of the acoustic assembly; alternatively, the suspension portion 2 and the soundproof assembly may be integrally formed in view of reduction in volume.

In order to facilitate the arrangement of the first opening 21 and the protruding portion 22 on the hanging portion 2 and facilitate the production of the mold and the assembly of the worker, the forming modes of the first opening 21 and the protruding portion 22 are formed by a numerical control punch press, laser cutting, die stamping, plasma or flame cutting, wire cutting, drilling or milling and the like, so that the production of the mold and the assembly of the worker are facilitated.

In a specific application scenario, the compressor 10 is fixed through the elastic component 1, the clamping piece 3 and the suspension part 2, so that the suspension arrangement of the compressor 10 is realized, and the vibration and noise problems of the compressor 10 are reduced. In the present embodiment, as shown in fig. 11, the number of the elastic assemblies 1 may be 6, and the elastic assemblies may be respectively disposed at the left and right sides of the compressor 10, and each side of the elastic assemblies may be 3; the number of the hanging parts 2 may be 2, which are respectively located at the left and right sides of the compressor 10 for fixing, and three first openings 21 are relatively arranged on each hanging part 2, and a protruding part 22 extending towards the inside of the first opening 21 is arranged on each first opening 21. The first end of the elastic component 1 is connected with the compressor 10, the second end of the elastic component is fixed with the clamping piece 3, the other end of the clamping piece 3 is clamped in the first opening 21, and therefore when the compressor 10 is in a suspended state, the clamping piece 3 is limited by the protruding portion 22 to be separated from the first opening 21. In order to facilitate the insertion of the card member 3 into the first opening 21, the thickness d of the card member 3 may be set smaller than the minimum distance h from the endmost end of the free end of the projection 22 to the inner side wall of the first opening 21 corresponding to the endmost end. Here, elastic component 1 may be an extension spring, clamping piece 3 may be a circular buckle, and as long as circular buckle is sleeved on boss 22, elastic component 1 obliquely holds compressor 10, compressor 10 can be suspended and does not fall off, and circular buckle only when being close to and perpendicular to hanging portion 2, clamping piece 3 can be taken out from first opening 21, so that installation is convenient, and the clamping piece 3 cannot fall off due to vibration of compressor 10. As shown in fig. 12 and 13, the free end of the protruding portion 22 is located in the plane of the first opening 21, and the directional component of the extending direction of the free end of the protruding portion 22 is the inner side wall toward the side of the first opening 21 close to the compressor 10. Because fastener 3 is circular latch, so when compressor 10 is in unsettled state, fastener 3 sets up with the free end of bellying 22 alternately, and circular latch can encircle the free end and carry out certain amplitude's rotation, when making elastic component 1 along with compressor 10 vibrations, moves more freely. In order to maximize the utilization of the force, at least a part of the ring-shaped structure of the clip member 3 is parallel to the length direction of the elastic member 1, and the arrangement is favorable for prolonging the service life of the elastic member 1.

Further, here, elastic component 1 and fastener 3 integrated into one piece, make things convenient for the batch production and the equipment of elastic component 1 and fastener 3, improve work efficiency.
