Description
Technical field
The utility model relates to a kind of locking mechanism adjusting the worm shaft of arm, is applied in the adjustment arm of automobile brake parts, is specifically related to a kind of worm shaft angle self-locking structure.
Background technique
At present, known hand regulation arm is formed by housing, worm gear, worm screw, worm shaft and other assembling fittings.The relative position that worm pin marble hole and pellet are cheated in worm shaft assembly process is difficult to ensure, causes rollback phenomenon to exist.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of worm shaft angle self-locking structure is provided, telescopic pin is utilized to be pinned on the limit of hexagonal, worm shaft cannot be rotated, during adjustment worm shaft, telescopic pin contracts inward and just can regulate, easy for installation, make simple, eliminate the rollback phenomenon existed in using.
For getting to above-mentioned purpose, the technical solution of the utility model is: worm shaft angle self-locking structure, comprise adjustment arm, worm shaft, telescopic pin, Compress Spring, column cap screw, worm gear, worm screw, described adjustment arm establishes axis hole, described axis hole runs through the interior Fang Xin that centre is established, upper end is parallel establishes pin-and-hole, vertical threaded bore is established in the upper end of described pin-and-hole, described worm gear loads in adjustment arm, Fang Xin and worm gear in worm screw loads, seal ring is inserted in the installation shelves that worm shaft is established, and be close to spindle nose inner plane, be pressed into equipment, described Compress Spring puts into pin-and-hole, described telescopic pin is put into, the flange outer end face of described telescopic pin afterbody props up Compress Spring, column cap screw is screwed in the axis hole of described adjustment arm, the head of described column cap screw screws in the space in intermediate groove.
Further setting, the installation shelves that described worm shaft is set and inner bore of worm are as fixing close-fit.
Further setting, the spindle nose of described worm shaft circumferentially establishes hexagonal.
The beneficial effects of the utility model are: utilize telescopic pin to be pinned on the limit of hexagonal, and worm shaft cannot be rotated, easy for installation, make simple, eliminate in using due to rollback phenomenon that the rotation of worm shaft produces; Column cap screw head screws in the space of the intermediate groove that telescopic pin is established, and eliminates the obscission of telescopic pin; Be provided with the Compress Spring withstood outward bottom telescopic pin, the normality being beneficial to telescopic pin remains on the hexagon of worm shaft peripheral hardware, blocks the rotation of worm shaft; While when regulating worm shaft instrument entangles hexagon, also make telescopic pin contract inward, twisting hexagonal rotates worm shaft and adjustable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the schematic diagram of telescopic pin in Fig. 1.
In figure: adjustment arm 1, pin-and-hole 11, screw 12, seal ring 13, interior side's core 14, axis hole 15, worm shaft 2, spindle nose 21, hexagonal 211, installation shelves 22, telescopic pin 3, intermediate groove 31, flange 32, Compress Spring 4, column cap screw 5, worm gear 6, worm screw 7.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in FIG. 1 to 3, worm shaft angle self-locking structure, comprise adjustment arm 1, worm shaft 2, telescopic pin 3, Compress Spring 4, column cap screw 5, worm gear 6, worm screw 7, described adjustment arm 1 establishes axis hole 15, described axis hole 15 runs through interior side's core 14 that centre is established, upper end is parallel establishes pin-and-hole 11, vertical threaded bore 12 is established in the upper end of described pin-and-hole 11, described worm gear 6 loads in adjustment arm 1, worm screw 7 loads interior side's core 14 and coordinates with worm gear 6, seal ring 13 is inserted in the installation shelves 22 that worm shaft 2 is established, and be close to spindle nose 21 inner plane, be pressed into equipment, described Compress Spring 4 puts into pin-and-hole 11, described telescopic pin 3 is put into, flange 32 exterior edge face of described telescopic pin 3 afterbody props up Compress Spring 4, column cap screw 5 is screwed in the axis hole 15 of described adjustment arm 1, the head of described column cap screw 5 screws in the space in intermediate groove 31.The utility model utilizes telescopic pin 3 to be pinned on the limit of hexagonal 211, worm shaft 2 cannot be rotated, easy for installation, make simple, eliminate in using due to rollback phenomenon that the rotation of worm shaft 2 produces, column cap screw 5 head screws in the space of the intermediate groove 31 that telescopic pin 3 is established, eliminate the obscission of telescopic pin 3, the Compress Spring 4 withstood outward is provided with bottom telescopic pin 3, the work normality being beneficial to telescopic pin 3 is the limit of the hexagonal 21 remaining on worm shaft 2 peripheral hardware, block the rotation of worm shaft 2, while during adjustment worm shaft 2, instrument entangles hexagonal 211 limit, also telescopic pin 3 is made to contract inward, twisting hexagonal 211 rotary worm axle 2 i.e. adjustable.
