Abstract
The utility model discloses a connection structure of an automobile adjustor output screw rod and an adjustor support embedded part, which belongs to an automobile adjustor and comprises a screw rod, a nut, an adjustor support and an adjustor support embedded part. The connection structure is characterized in that a flanging hole with the height about 2mm is arranged on the adjustor support embedded part; the screw rod is installed on the adjustor support embedded part; straight grains arranged at the bottom portion of the screw rod are extruded inside the flanging hole of the adjustor support embedded part; the screw rod and the adjustor support embedded part are molded into an adjustor support by an injection molding machine; and the nut is installed on the screw rod. The connection structure has the advantages that the screw rod can directly contact with the embedded part due to the fact that the adjustor support embedded part is made into the flanging hole so that contacting area of the straight grains of the screw rod and the embedded part is enlarged, and the problems that the screw rod is in virtual connection with the embedded part and the screw rod is non-conducted are resolved. The modified screw rod is higher than a plastic surface, and the nut can be directly rigidly connected with the screw rod, thereby resolving the problem that the nut is loose due to long-time vibration in using process, and increasing connection reliability.
Description
Technical field
The utility model relates to a kind of automotive regulator, particularly a kind of automotive regulator output screw and regulator bracket inserts syndeton
Background technology
At present, existing adjuster screw rod is because plastics have the characteristic of expanding with heat and contract with cold, and summer, because plastics are softer, screw rod voltage regulator support was no problem when assembling.Winter, plastics were very crisp when assembling, and screw rod is compressed into support and is easy to cause the support cracking, causes regulator bracket to be scrapped.Because inserts is to be injection-moulded in the regulator bracket, inserts is different with the amount of contraction of plastics, the inserts diameter was less than the diameter of plastic stent when temperature was low, and the thickness of inserts has only 0.6mm, screw rod is when press-fiting regulator bracket, can not reliable and effectively be connected with inserts, cause screw rod and inserts virtual connection, screw rod is non-conductive.Because nut directly is locked on the regulator bracket, plastics have contraction, in use are subjected to long vibrations, cause nut loosening, and it is unreliable to connect.
Summary of the invention
The purpose of this utility model is to stop the scrappage of regulator bracket when assembling, increases the reliability that screw rod is connected with inserts, guarantees the screw rod output current, prevents the nut loosening phenomenon.
The purpose of this utility model is achieved in that a kind of automotive regulator output screw and regulator bracket inserts syndeton, form by screw rod, nut, regulator bracket, regulator bracket inserts, it is characterized in that: on the regulator bracket inserts, be provided with height flange hole, the 2mm left and right sides, on the regulator bracket inserts, screw rod is housed, the bottom of screw rod is provided with straight burr, screw rod bottom straight burr is squeezed in the flange hole of regulator bracket inserts, and screw rod and regulator bracket inserts are injection molded into regulator bracket with injection molding machine.Nut is housed on screw rod.
Beneficial effect: owing to adopt such scheme, having solved regulator bracket ftractures when press-fiting screw rod easily, cause regulator bracket to scrap, and inserts is made the flange hole, make screw rod directly contact with inserts, increased the contact area of screw rod straight burr and inserts, solved screw rod and inserts virtual connection, the nonconducting problem of screw rod.Moreover the screw rod after improving is higher than frosting, and nut directly is rigidly connected with screw rod, can not cause in use to be subjected to long vibrations, causes nut loosening, has improved the reliability of connection.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1. screw rod 2. nuts 3. regulator brackets 4. regulator bracket inserts.
Embodiment
In figure, the utility model comprises screw rod, nut, regulator bracket, regulator bracket inserts composition, on regulator bracket inserts 4, be provided with height flange hole, the 2mm left and right sides, screw rod 1 is housed on regulator bracket inserts 4, the bottom of screw rod is provided with straight burr, screw rod 1 bottom straight burr is squeezed in the flange hole of regulator bracket inserts 4, and screw rod 1 and regulator bracket inserts 4 usefulness injection molding machines are injection molded into regulator bracket 3, and nut check is housed on screw rod.
