The specific embodiment
Below with reference to accompanying drawing and combine embodiment to specify the utility model.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
As shown in Figure 1, according to first embodiment of the utility model, screw connection structure comprises and is used for the connecting hole 10 that cooperates with external thread structure that the external thread structure here can be to have securing members such as externally threaded bolt, screw, double-screw bolt.Connecting hole 10 is a unthreaded hole; The internal perisporium of connecting hole 10 is provided with the holding tank 20 that in axial direction extends; Increased the space of connecting hole 10 through holding tank 20 is set, the smear metal material that produces when making the internal perisporium friction of thread and connecting hole 10 of external thread structure can have enough spaces to walk material, and fricative shear heat is discharged smoothly; Thereby reduce the suffered extrusion stress in threaded portion of shear heat and external thread structure, prevent connecting hole 10 crackings.This holding tank 20 is the rectangular recess that extends along connecting hole 10 axial directions, and has three.Circumferential direction evenly is provided with three rectangular recess at interval in the internal perisporium upper edge of connecting hole 10, and three rectangular recess length in axial direction is all identical with connecting hole 10 length in axial direction.
Because the existence of holding tank 20, when processing connecting hole 10, can the aperture suitably be done little, thereby increase the thread and the mesh degree of connecting hole 10 inwalls of external screw thread member, the generation of minimizing stripped thread phenomenon.
In conjunction with referring to Fig. 2, according to second embodiment of the utility model, itself and first example structure are basic identical, and difference is that holding tank 20 comprises four rectangular recess.Circumferential direction evenly is provided with four rectangular recess at interval in the internal perisporium upper edge of connecting hole 10, and four rectangular recess length in axial direction is all identical with connecting hole 10 length in axial direction.Four bigger situation in aperture that rectangular recess is applicable to connecting hole 10, it is compared three rectangular recess and can provide and more walk material space.
Here the quantity of rectangular recess is not limited to three or four, should be provided with according to actual needs.
In conjunction with referring to Fig. 3; The 3rd embodiment according to the utility model; Itself and first example structure are basic identical, and difference is the V-shaped groove of holding tank 20 for extending along connecting hole 10 axial directions, and the two opposite side walls of V-shaped groove be the planar structure along the axial direction extension of connecting hole 10.Three V-shaped grooves that evenly are provided with at interval along the circumferential direction of connecting hole 10 internal perisporiums make the radial section of connecting hole 10 become triangle.The smear metal material that produces when screwing in external thread structure can be pressed in leg-of-mutton three angles, promptly is squeezed in three V-shaped grooves, thereby reduces shear heat greatly, effectively prevents cracking.Simultaneously because the existence of holding tank 20, when processing connecting hole 10, can the aperture suitably be done little, thereby increase the thread and the mesh degree of connecting hole 10 inwalls of external screw thread member, the generation of minimizing stripped thread phenomenon.
In conjunction with referring to Fig. 4, according to the 4th embodiment of the utility model, itself and the 3rd example structure are basic identical, and difference is the globoidal structure that the two opposite side walls of V-shaped groove is extended for the axial direction along connecting hole 10.Three V-shaped grooves that evenly are provided with at interval along the circumferential direction of connecting hole 10 internal perisporiums make the radial section of connecting hole 10 become prismatic.
Here the quantity of V-shaped groove is not limited to three, should be provided with according to actual needs.
In conjunction with referring to Fig. 5; The 5th embodiment according to the utility model; Be processed with four installing and locating steps on the motor cabinet 60 of air-conditioner; Then on four installing and locating steps respectively correspondence be processed with screw connection structure, this screw connection structure comprises four connecting hole 10a, 10b, 10c and 10d, and the internal perisporium of connecting hole 10a, 10b, 10c and 10d is provided with aforementioned any holding tank 20 as required.Four installing and locating step corresponding sections with motor cabinet 60 on baffle liner 50 are processed with four screw via hole 40a, 40b, 40c and 40d, and the position of four connecting hole 10a, 10b, 10c and 10d is corresponding one by one with the position of four screw via hole 40a, 40b, 40c and 40d respectively.
When assembling motor cabinet 60 and baffle liner 50; Earlier four installing and locating steps on the motor cabinet 60 are inserted four screw via hole 40a, 40b, 40c and 40d on the baffle liner 50 respectively; Screw among four connecting hole 10a, 10b, 10c and the 10d and screw four screw 30a, 30b, 30c and 30d are corresponding respectively then, thereby motor cabinet 60 is fixedly connected with baffle liner 50.
Aforesaid screw connection structure can also be applied to air-conditioner other have in two adjacent members of annexation, and at least one member in two adjacent members should possess aforesaid screw connection structure.
In conjunction with referring to Fig. 6～10; The 6th embodiment according to the utility model; The baffle liner 50 of air-conditioner is provided with a plurality of screw connection structures; And connecting hole 10 places of each screw connection structure are provided with different holding tank 20 as required, when preventing that baffle liner 50 is connected with other members, and connecting hole 10 cracking or external thread structure stripped threads.
From above description, can find out; The utility model the above embodiments have realized following technique effect: through holding tank is set in connecting hole; For between external screw thread member and the connecting hole inwall because fricative smear metal material provides the space of material; And shear heat can be discharged smoothly, thereby reduced the possibility of connecting hole cracking.Simultaneously because the existence of holding tank, so when the processing connecting hole, can the aperture suitably be done little, thereby increase the thread and the mesh degree of connecting hole inwall of external screw thread member, the generation of minimizing stripped thread phenomenon.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
