The utility model discloses the locking positioning is firm, and is safe practical.

Description

Flexible thick stick

Technical field

The utility model relates to field of exercise, particularly relates to a kind of flexible thick stick.

Background technology

Flexible thick stick is as health and fitness facilities, be used to grasp after support is jumped up for body builder between two facades thus carry out the action of chin-up class, existing flexible thick stick all carries out the location after stretching by means of only the spiral shell fixing structure that screws of stage casing thick bar and both sides thin bar, and jump up very swift and violent to its dynamics grasped instantaneously due to body builder, this only by screwing the risk that releasing just easily appears in the solid location structure of spiral shell, there is very large potential safety hazard.

Utility model content

In view of this, technical problem to be solved in the utility model is: provide a kind of flexible after locking positioning firmly firm, safe and practical flexible thick stick.

In order to achieve the above object, the utility model adopts following technical scheme to realize:

A kind of flexible thick stick, comprise scalable with the expansion link of support between two facades, described expansion link comprises stage casing thick bar and is connected in thick bar two ends, described stage casing sleeve and can screws the both sides thin bar be fixed in the thick bar of described stage casing, wherein, described expansion link is at least provided with locking device in one end in self, described locking device comprises the locking bed of sleeve on described thick bar termination and is set in the locking head in described thin bar, described thick bar is slitted and is provided with bayonet socket on the termination being inserted with described locking bed, described locking bed is convexly equipped with the dop snapping in described bayonet socket on the end face of the described bayonet socket of correspondence, socket is arranged with on the end face of described bayonet socket dorsad, described locking head is convexly equipped with the plug be connected in order to plug-in card in described socket on the end face towards described locking bed, described thin bar is arranged with rail groove vertically on the shaft outer wall being coated with described locking head, described locking head is convexly equipped with and snaps in described rail groove to limit the limited block that described locking head can only slide along described rail groove on the inwall of the described thin bar of socket, the described socket be located on described locking bed be spaced multiple to screw in described thin bar and to be fixed in described thick bar to diverse location time insert for described plug.

As preferably, described expansion link is equipped with described locking device in self two ends.

As preferably, outside described thick bar, be arranged with soft sheath.

As preferably, described thin bar is screw the structure be screwed in described thick bar.

As shown from the above technical solution, the beneficial effects of the utility model are:

Compared to existing technology, in the utility model, flexible rear locking positioning is firmly firm, safe and practical.
