Abstract
Provided is a connecting and locking device of steel pipes in different diameters at the supporting legs of a support, and the supporting legs of the support are composed of the steel pipes in different diameters, the height of the supporting legs can be adjusted by adjusting the length of the steel pipes, normally, the connecting and locking device of the steel pipes in different diameters is used. A steel jacket is arranged in the steel pipe with big diameter for restrict the radial displacement of the steel pipe in small diameter, the top of the steel pipe with big diameter is provided with two square grooves, two protruding parts are arranged on a locking piece to insert in the square grooves of the steel pipe with big diameter, the locking piece is locked through the cooperation of a semicircular head and square neck bolt and a locking handle, so the protruding parts of the locking piece cooperate with the steel jacket to lock the steel pipe with small diameter to realize the connection of the steel pipes in different diameters, a plastic cover is arranged at the upper part for beauty and sealing, one only needs to screw up the locking handle to adjust the support to a proper height. The connecting and locking device provided is simple in assembling, convenient in adjustment, and flexible in detachment, in addition, the connecting and locking device provided solves the problems that the welding is non-detachable, the two steel pipes are easy to tilt while connecting with a fastening screw, and the coaxiality is bad.
Description
Technical field:
The supporting leg place different-diameter steel pipe that the utility model relates to various supports connects locking device.
Background technique:
Support is a common equipment in the productive life; because of the different of working environment, place and to produce the difference etc. of product size all multifactor; support is in the process of using; need adjust the height of support supporting leg according to the needs of actual conditions; supporting leg generally is made up of the steel pipe of different-diameter; the connection length of regulating steel pipe can be adjusted the height of supporting leg, and the supporting leg different-diameter steel pipe that can use support usually connects locking device.
Summary of the invention:
The utility model has adopted the supporting leg different-diameter steel pipe that is applicable to various supports to connect locking.
The utility model technological scheme that is adopted of dealing with problems is: added a cover in support supporting leg different-diameter steel pipe joint and connected locking device, promptly in the large diameter steel pipe at the supporting leg place of support, steel bushing is housed, radial displacement in order to the restriction minor-diameter steel-tube, the large diameter steel pipe top has two square grooves, lock sheet has been cooked two outstanding parts, just be embedded in the square groove of large diameter steel pipe, utilize half-round head square neck bolt and set lever to cooperate, the locking lock sheet, make lock sheet projection cooperate steel bushing, the locking minor-diameter steel-tube has been realized the connection of different-diameter steel pipe, for the top at locking device attractive in appearance, vinyl cover is housed, not only play effect attractive in appearance, also play good seal action, when needing to adjust the height of support, unclamp set lever, adjust to suitable height, screw set lever and get final product, wherein lock sheet, steel bushing is a stamping part.
The beneficial effects of the utility model are not only can realize the connection of different-diameter steel pipe when the making of support, and assembling to be simple, easy to adjust, flexibly detachable, it is non-dismountable to have solved welding, reach when using Cock screw to connect, two steel pipes are easy to generate crooked, the problem of coaxality difference.
Description of drawings:
Below in conjunction with accompanying drawing and example the utility model is further specified.
