Abstract
The utility model relates to the technical field of a fastening component, in particular to an elastic pin special for a compressor on refrigerating equipment. The technical scheme is that the elastic pin comprises a hollow cylindrical elastic pin body, wherein a through groove is formed in the elastic pin body along the axial direction; and a shrinking opening is respectively formed in each of the two axial end parts of the elastic pin body in the way of shrinking an opening. Compared with the prior art, the elastic pin has the advantages of simple and convenient assembly, and stable and reliable utilization performance after assembly.
Description
Technical field
The utility model relates to technical field of fastening, is specifically related to compressor dedicated elas-tic pin on a kind of chiller plant.
Background technique
Compressor is vitals on the chiller plant, and the resilient key that uses on the existing compressor is the cylindrical body of hollow without a head, and is axially grooved, possesses good elasticity and anti-shearing force, and its external diameter is more slightly bigger than the assembling aperture; There is the assembly manipulation difficulty in the resilient key of said structure, and scrapping easily appears damaging in assembling by force.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide easily compressor dedicated elas-tic pin on the chiller plant of a kind of orientation assemble.
For achieving the above object, the utility model provides following technological scheme: compressor dedicated elas-tic pin on a kind of chiller plant, include the cylindrical resilient key body of hollow, offer vertically groove on the described resilient key body, it is characterized in that: described resilient key body shaft is processed to form reducing to two end part through closing in.
By adopting technique scheme, make things convenient for the resilient key location to insert in the pilot hole, thereby make things convenient for its assembling, assembly process Elastic pin is not fragile, thereby guarantees that resilient key is reliable after assembling.
The utility model further is set to: the reducing on the described resilient key body is for conical.
Reducing on the described resilient key body is that axial length is the conical reducing of 1.4 ~ 1.8mm.
The hollow circular cylinder that the high carbon steel that described resilient key body employing thickness is 0.25 ~ 0.35mm is made.
By adopting technique scheme, reducing is adopted conical, orientation assemble is more convenient, and is in the assembly process, less to the damage of reducing simultaneously, guarantee the reliability of resilient key, the setting of reducing length meets the assembling demand of compressor, the oversize effect that then weakens resilient key itself, too short then assembling inconvenience, the resilient key made of this material draws through test and has traditional twice shear strength simultaneously, is about 1890N.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is Figure 1A part partial enlarged drawing
Embodiment
Referring to accompanying drawing 1 and Fig. 2, compressor dedicated elas-tic pin on the disclosed a kind of chiller plant of the utility model includes the cylindrical resilient key body 1 of hollow, and described resilient key body 1 is the hollow circular cylinder that the high carbon steel of 0.25 ~ 0.35mm is made for adopting thickness; Offer vertically groove 2 on the described resilient key body 1, described resilient key body 1 axial two end part are processed to form reducing 3 through closing in.Reducing 3 on the described resilient key body 1 is conical; Reducing 3 on the described resilient key body 1 is the conical reducing of 1.4 ~ 1.8mm for axial length.Lower reducing 3 is set like this to be adopted conical, orientation assemble is more convenient, simultaneously in the assembly process, damage to reducing 3 is less, guarantees the reliability of resilient key, and reducing 3 length settings meet the assembling demand of compressor, the oversize effect that then weakens resilient key itself, too short then assembling inconvenience, the resilient key made of this material draws through test and has traditional twice shear strength simultaneously, is about 1890N.
