Description
Technical field
The utility model relates to that a kind of cooperation is fixing use structure, is specifically related to a kind of reservoir clip and cooperates the structure of fixing with support.
Background technology
General existing rotator type idle call compressor, reservoir top cooperates with the reservoir support by the clip of camber, clip and the little hook of support one end interlock, and the other end is that tapping screw screws clip and support are fitted, and the stretcher strain by clip is to being locked.As depicted in figs. 1 and 2, clip with the operation principle that the reservoir support is fixed reservoir is: the little crotch of clip left end is interlocked with the reservoir support is connected earlier, the bolt hole of tapping screw by the clip right-hand member is screwed on the reservoir support in (tapping screw) bottom outlet again.Because in tapping screw screw-in process, the right-hand member plane and the reservoir support right-hand member plane of clip can be fitted tightly, this moment, clip was influenced by the pulling force that axially screws pressure and vertical axial of tapping screw, clip produces distortion, reservoir is locked securely, while reservoir bottom guarantees that like this realization of reservoir and compressor housing is completely fixed owing to fix by air-breathing copper pipe of reservoir and compressor housing welding.
But in actual production, in transportation and the use, often occur because clip is excessive to the shearing force of the vertical axial of tapping screw, perhaps tapping screw quality control reason, hydrogen embrittlement problem (that is: constantly micro-crack appears in infiltration to screw matrix stress concentration place because of the hydrogen atom in pickling and the galvanizing process in the electrogalvanizing) very easily appears, cause the fracture of tapping screw root to influence the compressor operating reliability problems at last, majority is to adopt the reduction clip that the shearing force of the vertical axial of tapping screw or the production and supply quality of reinforcement tapping screw are controlled solution in this case.But can bring the fixing danger that tightly and does not easily cause the reservoir copper pipe in compressor operating, to vibrate fracture of reservoir owing to adopt reduction screw shearing force, and tapping screw is because be the outside screw specialized factory that purchases, and because tapping screw adopts galvanizing technique, the controlling of production process that adds tapping screw in stressed bigger situation was not at that time, will occur that the hydrogen embrittlement problem causes the fracture of screw and the reliability that influences compressor liquid storage device has increased compressor controllable quality difficulty so undoubtedly.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of stressed hydrogen embrittlement that prevents that improves tapping screw for the defective that overcomes above-mentioned prior art existence, and the reservoir clip that improves reliability of products cooperates fixing structure with support.
The purpose of this utility model can be achieved through the following technical solutions: a kind of reservoir clip cooperates fixing structure with support, this structure comprises the reservoir support, tapping screw, earthing screw, clip, reservoir, described reservoir support is provided with tapping screw hole and earthing screw hole, described clip one end is provided with little hook and the reservoir support interlocks, the other end is provided with the tapping screw hole, described tapping screw passes the tapping screw hole on clip and the reservoir support, clip is fitted with the reservoir support fixedlys connected, it is characterized in that, be provided with a through hole between tapping screw hole and the earthing screw hole on the described reservoir support, the end that described clip is provided with the tapping screw hole is provided with baby hem, this baby hem passes the through hole on the reservoir support, interlocks with this through-hole side.
The center, position, hole, tapping screw hole on the described clip and the dead in line of tapping screw.
The little hook of one end of described clip for interlocking with the reservoir support, the other end for the reservoir support on the baby hem that is complementary of through hole.
Compared with prior art, the utility model is by increasing a bit of bending edges on clip, on the reservoir support, increase a through hole, can improve the tapping screw stressing conditions effectively, owing to directly affact the tightening force of the clip baby hem by new change structure on the support, tapping screw only need bear axial force and the moment of torsion that locking causes, the shearing force of no longer bearing the easiest generation hydrogen embrittlement fracture.Reach the stressed hydrogen embrittlement that prevents that improves tapping screw, improve the compressor reliability of products.The basic no change of manufacturing cost and material cost does not need to increase other annex again, not only improves the stressed hydrogen embrittlement that prevents of tapping screw, and installs very simply, reliably, has stronger practical value.Be applicable in compressor, air-conditioner, refrigerator and the Teat pump boiler.

Embodiment
Shown in Fig. 3～4, a kind of reservoir clip of compressor cooperates fixing structure with support, this structure comprises reservoir support 1, tapping screw 2, earthing screw 3, clip 4, reservoir 5, described reservoir support 1 is provided with tapping screw hole 6 and earthing screw hole 7, described clip 4 one ends are provided with little hook 8 and interlock with reservoir support 1, the other end is provided with tapping screw hole 9, described tapping screw 2 passes the tapping screw hole 9 on clip 4 and the reservoir support 1,6, clip 4 is fitted with reservoir support 1 fixedlys connected, be provided with a through hole 10 on the described reservoir support 1 between tapping screw hole 6 and the earthing screw hole 7, the end that described clip 4 is provided with tapping screw hole 9 is provided with baby hem 11, this baby hem 11 passes the through hole 10 on the reservoir support 1, interlocks with these through hole 10 sides.
By through hole 10 of (as shown in Figure 3, between tapping screw bottom outlet and ground connection screw) processing on reservoir support 1, simultaneously at the clip 4 tapping screw holes 9 other baby hems 11 that increase.When tapping screw 2 constantly screws in, the new baby hem 11 of clip 4 enters in the through hole 10 that the reservoir support newly leaves gradually and begins to interlock with the hole side and contacts, when tapping screw 2 is screwed into root and reaches prescribed torque, be positioned at the center, position, screwing through hole 9 hole on the clip 4 and the dead in line of tapping screw 2.After this moment, clip 4 interlocked with support 1 by new baby hem 11, the tension that clip 4 locking reservoirs 5 produce just is delivered on the support 1 by new baby hem 11, can not produce any shearing force to tapping screw, thereby improve the stress of tapping screw, reduce even stopped the possibility of tapping screw generation hydrogen embrittlement fracture.
Above-mentioned reservoir clip cooperates fixing structure also to be applicable in air-conditioner, refrigerator and the Teat pump boiler with support.
