Description
Technical field
The utility model belongs to Household body-building technical field, is specifically related to horizontal bar on a kind of door with self-locking device.
Background technology
On door, horizontal bar is as a kind of Household fitness equipment, and because its occupied ground is less, convenient exercise operates and be widely used.On the door of prior art, horizontal bar is mainly made up of left and right rotating extensible arm and middle screw mandrel, left and right rotating extensible arm is rotatably provided in middle screw mandrel by rotating, extend extruding doorframe by middle screw mandrel rotating in use, make the frictional force that the end of left and right rotating extensible arm and doorframe produce.In order to reduce the gap that the working of plastics on the two ends of intermediate bar are overlapped of the gap between intermediate bar and left and right rotating extensible arm reduces between the two.In actual use, by when on door, horizontal bar is fixed on doorframe, left and right lid can be subject to the uniform force on doorframe, make horizontal bar on door can firmly on doorframe, but when people horizontal bar operates on door, meeting produces a downward gravity on intermediate bar, and the gravity that intermediate bar is subject to can to left and right rotating extensible arm transmission, owing to there being gap that intermediate bar can be made to drop between intermediate bar and left and right rotating extensible arm, bending.And between intermediate bar and left and right rotating extensible arm, only have the top just to have contact face little.When people horizontal bar moves on door for a long time, make gravity on intermediate bar distribute uneven intermediate bar bending and produce certain use safety, easily potential safety hazard is produced to the people that horizontal bar on door moves, be difficult to meet the need of market.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides that a kind of structure is simple, stability in use and horizontal bar on the strong door with self-locking device of usage safety performance.
The technical scheme realizing the utility model object is: horizontal bar on a kind of door with self-locking device, comprise intermediate bar, anticlockwise expansion link and right rotation expansion link, described intermediate bar is that hollow is arranged, described anticlockwise expansion link and right rotation expansion link are separately positioned on a left side for intermediate bar, right two ends, screw mandrel is had at described intermediate bar internal fixtion, described anticlockwise expansion link and right rotation expansion link are rotatably connected at the two ends of screw mandrel respectively, left self-locking device is provided with in the junction of described anticlockwise expansion link and described intermediate bar, right self-locking device is provided with in the junction of described right rotation expansion link and described intermediate bar, internal thread is equipped with at the two ends inwall of described intermediate bar, external screw thread is equipped with at the outer wall of described left self-locking device and right self-locking device, described left self-locking device and right self-locking device screw regulating type are connected on the two ends of intermediate bar.
Described left self-locking device and right self-locking device are by connecting portion, self-locking fastening part and baffle ring portion composition, described external screw thread is arranged on connecting portion, the outer wall of described self-locking fastening part is for be obliquely installed and inclination small end is arranged near baffle ring portion near the connecting portion large end that tilts, described self-locking fastening part and baffle ring portion are provided with vertical slot, the two ends of described intermediate bar are set to rake, and the large end of described rake is arranged on the end of intermediate bar.
The end face of left and right rotating extensible arm is equipped with friction pad.
The utility model has positive effect: structure of the present utility model is simple, left and right self-locking device is provided with at left and right rotating extensible arm and intermediate bar junction, in use, first left and right rotating extensible arm is rotated and stretch out intermediate bar, make it to produce pressure between doorframe, then fixed tightening lock-bit between left and right rotating extensible arm and intermediate bar by left and right self-locking device, effectively can prevent in use left and right rotating extensible arm self-resetting type retraction, improve stability in use and safety in utilization, applicability is good, practical.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein:
