Description

Compressor controller casing assembly structure
Technical field
This utility model is related to housing encapsulation technology field, more particularly to a kind of compressor controller casing assembly structure.
Background technology
The casing assembly of scroll compression machine controller generally includes housing and lid, and sealing gasket is housed between housing and lid Piece, so that favorable sealing property between housing and lid, plays a part of waterproof and dustproof and prevent gas from penetrating into.Shell Four angles of body are provided with through hole, and four angles of lid are provided with screwed hole corresponding with through hole, and bolt passes through through hole and screw thread Hole connects, and as tightening for bolt, gasket seal are compressed, realizes being tightly connected for housing and lid.Yet with sealing gasket The decrement of piece is relevant with the tightness of bolt, and it is tighter that bolt is twisted, and the decrement of gasket seal is bigger(Gasket seal Thickness is less), bolt twist tension, the outer weekly assembly crimp of gasket seal and bloat, affect very much attractive in appearance, bolt twist too Loose then sealing property is not enough;It is difficult to ensure that the elasticity of four bolts is consistent in actual rundown process, so on the one hand cause The different parts decrement of gasket seal is inconsistent, on the other hand causes the overall high of different compressor controller casing assemblies Degree has differences.Also there is a kind of method control the elasticity of bolt now, i.e., bolt is twisted using torque spanner, control each Moment of torsion when bolt is tightened, thus has a strong impact on the efficiency of assembling of lid and housing.
Utility model content
This utility model is in order to difficult when overcoming that housing is connected with lid in compressor controller casing assembly in prior art Effectively to control the deficiency of the deformation quantity of gasket seal, there is provided a kind of deformation quantity that can accurately control gasket seal, lid Body assembles convenient compressor controller casing assembly structure with housing.
To achieve these goals, this utility model is adopted the following technical scheme that:
A kind of compressor controller casing assembly structure, including housing and lid, are provided between described housing and lid Gasket seal, four angles of the lid are provided with through hole, and four angles of the opening of the housing are provided with through hole one by one Corresponding screwed hole, four angles of described gasket seal are provided with and avoid hole correspondingly with through hole, and each is avoided in hole Rigid limit set is equipped with, the height of the rigid limit set is provided with bolt in described through hole less than the thickness of gasket seal, Described bolt is connected through rigid limit set with screwed hole.Rigid limit is covered for limiting the deformation quantity of gasket seal, with Bolt is tightened, and gasket seal is constantly compressed, when the two ends end contact respectively with lid, housing of rigid limit set During support, bolt cannot continue to be screwed into, and now then represent that bolt is screwed into place;The height that the thickness of gasket seal is covered with rigid limit Difference is the decrement of gasket seal, according to the corresponding rigid limit set of the different replacings of thickness of gasket seal;Lid and housing During practical set, it is only necessary to bolt is screwed to bottom by box spanner(Till cannot being rotated further), it is just that lid is close with housing Envelope connection, gasket seal decrement are suitable, not only will not deformation excessively but also can guarantee that good seal.
Preferably, some deformation escape groove are equipped with the two sides of the gasket seal, the gasket seal it is interior Portion is provided with support frame.On the one hand deformation escape groove causes that gasket seal deformation resistance is little, and bolt is screwed into more laborsaving, the opposing party Face is prevented from bulging when gasket seal is squeezed.
Preferably, described bolt includes bolt head and stud, the bolt head is stretched out with the connection end of stud Support pad is formed, the end face of the support pad is provided with seal washer.Seal washer plays sealing function, is prevented from the external world Moisture, air enters through hole, in screwed hole, prevents bolt and the junction of screwed hole from getting rusty.
Preferably, the opening of the screwed hole is provided with taper chamfering, the lower end of the rigid limit set is provided with and cone The cone boss that shape chamfering coordinates.When rigid limit set loads in avoidance hole, cone boss is snapped at taper chamfering automatically, so as to So that rigid limit set is alignd with the automatic axis of screwed hole.
Preferably, the upper end of the rigid limit set is provided with cannelure, elastic pretension pad in described cannelure, is provided with Piece.When bolt is tightened, elastic tightening cushion is tensioned rigid limit set and lid end face, so as to prevent bolt because of vibration Unclamp.
Therefore, this utility model has the advantages that:(1)The deformation quantity of gasket seal can accurately be controlled, neither Meeting deformation excessively can guarantee that good seal again;(2)After lid is connected with housing, housing bottom surface is highly consistent with lid top surface.
Description of the drawings
Fig. 1 is a kind of structural representation of the present utility model.
Top views of the Fig. 2 for Fig. 1.
Fig. 3 is close-up schematic view at A in Fig. 1.
In figure:Housing 1, lid 2, gasket seal 3, through hole 4, screwed hole 5, avoid hole 6, rigid limit set 7, bolt 8, close Seal washer 9, elastic tightening cushion 10, deformation escape groove 30, support frame 31, taper chamfering 50, cone boss 70, support pad 80。
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is further described:
A kind of compressor controller casing assembly structure as shown in Figure 1, Figure 2 and Figure 3, including housing 1 and lid 2, shell Gasket seal 3 is provided between body and lid, four angles of lid are provided with through hole 4, and four angles of the opening of housing are provided with With the one-to-one screwed hole 5 of through hole, four angles of gasket seal are provided with and avoid hole 6 correspondingly with through hole, and each is kept away Allow Bolt is connected through rigid limit set with screwed hole;Some deformation escape groove 30, sealing gasket are equipped with the two sides of gasket seal 3 The inside of piece 3 is provided with support frame 31.
Bolt 8 includes bolt head and stud, and bolt head stretches out to form support pad 80 with the connection end of stud, supports The end face of pad is provided with seal washer 9;The opening of screwed hole 5 is provided with taper chamfering 50, the lower end of rigid limit set 7 be provided with The cone boss 70 that taper chamfering coordinates;The upper end of stop collar is provided with cannelure, and elastic tightening cushion 10, bullet are provided with cannelure Property tightening cushion can be spring shim or taper pad.
Rigid limit is covered for limiting the deformation quantity of gasket seal, and with tightening for bolt, gasket seal is constantly pressed Contracting, when the two ends of rigid limit set are supported with the end contact of lid, housing respectively, bolt cannot continue to be screwed into, now Then represent that bolt is screwed into place, bolt tighten after by elastic tightening cushion pretension, prevent from loosening because of vibration, lid and housing Between connect more stable.
