Abstract
The utility model discloses an elastic ejection head structure. An extensible ejection head is inserted into a fixed sleeve body, the inner-end portion of the fixed sleeve body is provided with an inward-turnup blocking edge, the outer peripheral face of the extensible ejection head is provided with a shaft ring in ejecting match with the blocking edge in a protruding mode, and a locking nut is screwed at the rear end of the fixed sleeve body through threads. The rear end of the locking nut is provided with a turnup edge in ejecting match with the rear end face of the fixed sleeve body, a reset spring sleeves the extensible ejection head, the front end of the reset spring ejects the shaft ring, and the rear end of the reset spring ejects the turnup edge. The fixed sleeve body can be fixed on one of two parts assembled in a mutual-sliding mode, the other part is provided with an upper limiting hole, and the extensible ejection head in the fixed sleeve body extends into the limiting hole so as to achieve limiting of the two parts. The extensible ejection head is long and can extend into the limiting hole, the positioning effect is good, and the reset spring provides non-retracting force for the extensible ejection head, so that the elastic ejection head structure is reliable in positioning.
Description
Technical field
The utility model relates to a kind of elastic top header structure, belongs to a kind of mechanical localization mechanism, can realize two location between parts.
Background technique
Location between two parts is generally divided into stationary positioned structure and activity orientation structure, stationary positioned structure is mainly bolt, and activity orientation structure mainly contains pin, the occasion that needs relative sliding at some two parts, also need the location of position structure to be removed, the structure of conveniently having located contact location is common in the prior art is a kind of on parts, be provided with a blind hole, in blind hole, be provided with upper spring, the oral area anticreep of blind hole arranges a steel ball, steel ball withstands on spring, the positioning hole snapping in for steel ball is set on another one parts, steel ball enters positioning hole just can realize the location of two parts, on two parts, add make both relative slidings power exactly can so that steel ball from positioning hole, deviate from, realize the releasing of two location between parts.The reliability of this position structure is not high, just may lose efficacy, and two parts that are slidably matched is held to such power very much once two parts are stressed.
Model utility content
The purpose of this utility model is to provide a kind of elastic top header structure, to solve prior art because the reliable not high problem of position structure.
In order to realize above object, the utility model adopts following technological scheme: a kind of elastic top header structure, comprise fixedly body, fixedly body interpolation is provided with flexible top, fixedly body is stretched out at the two ends of flexible top, the gear edge that fixedly inner end of body turns in having, on the outer circumferential face of flexible top, convex with and the axle collar of described gear along top press fit, fixedly the rear end screw thread of body is installed with locking nut, the rear end of locking nut has and the turning edge of the ear end face top press fit of fixing body, on flexible top, be arranged with Returnning spring, the front end top of Returnning spring is pressed on the axle collar, on top, rear end is pressed in and turns edge.
On the outer circumferential face of fixing body, in the place ahead of locking nut, convex with fixedly bulge loop.
Fixedly body of the present utility model can be fixed on in two parts of mutual slidable fit, on another parts, offer upper limit hole, flexible top in fixed cover is stretched in spacing hole, realize the spacing of two parts, flexible top is longer, can go deep in spacing hole, good positioning effect, on the axle collar that is necessarily pressed in flexible top of Returnning spring, the other end top is pressed in and on fixed cover, is fixed on the turning edge of locking nut, for flexible top provides the power that remains on the state not bouncing back, make location of the present utility model reliable, when needs are removed location, can apply pulling force in the rear end of flexible top, make its overcome Returnning spring in retract, realize the releasing of location.And could realize only so the releasing of location, functional reliability is high.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
An embodiment for elastic top header structure, in Fig. 1, it is fixedly inserted with flexible top 1 in body 2, and the fixedly two ends of body 2 are stretched out respectively at the two ends of flexible top 1.At gear that fixedly front end of body 2 turns in having along 7, on the outer circumferential face of flexible top 1, convex with the axle collar 6, the axle collar 6 and gear are along 7 top press fits, fixedly the rear end screw thread of body 2 is installed with locking nut 4, in the rear end of locking nut 4, have and turn edge, this turns edge and the fixedly ear end face top press fit of body 2.On flexible top 1, be arranged with Returnning spring 5, the front end top of Returnning spring 5 is pressed on the axle collar 6, on top, the rear end of Returnning spring 5 is pressed in and turns edge.
On the outer circumferential face of fixing body 2, be provided with fixedly bulge loop 3, fixedly between bulge loop 3 and the front-end face of locking nut 4, there is spacing.
Elastic top header structure in the present embodiment is used on the rope brake of elevator.
Claims (2)
1. an elastic top header structure, it is characterized in that: comprise fixedly body, fixedly body interpolation is provided with flexible top, fixedly body is stretched out at the two ends of flexible top, the gear edge that fixedly inner end of body turns in having, on the outer circumferential face of flexible top, convex with and the axle collar of described gear along top press fit, fixedly the rear end screw thread of body is installed with locking nut, the rear end of locking nut has and the turning edge of the ear end face top press fit of fixing body, on flexible top, be arranged with Returnning spring, the front end top of Returnning spring is pressed on top, axle collar Shang， rear end is pressed in and turns edge.
