Abstract

A column height adjusting mechanism of a show shelf comprises an outer pipe and an inner pipe, which is inserted into the cavity of the outer pipe. The inner pipe is provided with a plurality of locating holes, which are arranged along the height direction. A positioner, which is provided with a pin and is at the locking work position, is sleeved on the inner pipe. The pin is inserted into the locating hole. When the positioner is under unlocking work position, the pin is departed from the locating hole, and the inner pipe is slidingly connected with the outer pipe. The positioner only needs being put on the end of the beveled outer pipe without any fixing, and the column height adjusting is simple and the usage is convenient.

Description

The column height adjustment mechanism of showing stand

Technical field

The utility model relates to the column height adjustment mechanism of the showing stand in a kind of supermarket.

Background technology

In the prior art, the column of showing stand is inserted in by interior pipe to be slidingly connected mutually in the inner chamber of outer tube and forms, and has a plurality of locating holes on the interior pipe, be provided with between interior pipe and the outer tube latch be used to lock in the relative position of pipe and outer tube.No matter be that interior pipe is heightened or turned down, all need to go out latch that this structure operation inconvenience is inserted in the corresponding hole in relative slip between pipe and the outer tube at last in making by latch with hand-lifting.

Summary of the invention

The purpose of this utility model is to provide a kind of column height adjustment mechanism of easy to operate showing stand.

The technical solution of the utility model is: a kind of column height adjustment mechanism of showing stand, comprise outer tube, be inserted in the interior pipe in the inner chamber of described outer tube, a plurality of locating holes of arranging along short transverse are arranged on the pipe in described, be with locator on the pipe in described, locator is provided with latch, be at locator under the operating position of locking, described latch is inserted in the locating hole; Be at locator under the operating position of release, described latch breaks away from described locating hole, and described interior pipe is slidingly connected with outer tube.

The specific embodiment

A kind of column height adjustment mechanism of showing stand, comprise outer tube 1, be inserted in the interior pipe 3 in the inner chamber of described outer tube 1, a plurality of locating holes of arranging along short transverse 4 are arranged on the pipe 3 in described, be with locator 2 on the pipe 3 in described, locator 2 is provided with latch 6, be at locator 2 under the operating position of locking, described latch 6 is inserted in the locating hole 4; Be at locator 2 under the operating position of release, described latch 6 breaks away from described locating hole 4, and described interior pipe 3 is slidingly connected with outer tube 1.

Described locator 2 is arranged at the upper surface of outer tube 1.The upper surface of described locator 2 is inclined-plane 7, and the plane at these 7 places, inclined-plane and the angle of horizontal plane are acute angle.Described locator 2 comprises positioner frame 5 and latch 6, and latch 6 is fixed on the described positioner frame 5, and latch 6 extends in frame.

During pipe 3 (when column is heightened), latch 6 can be separated with locating hole 4 automatically in drawing on directly, and interior pipe 3 can slide relatively with outer tube 1, and finally latch 6 is inserted in one of them locating hole 4, and then the adjusting of the height of column puts in place.When column will be turned down, as long as a bit of moving on the interior pipe 3, skid off locating hole 4 to latch 6 after, live locator 2 with hand rest, again with interior pipe 3 toward being displaced downwardly to needed position, again usefulness locator 2 fixedly positioning hole corresponding 4 get final product.2 needs of locator are placed on the outer tube upper end of being cut into the inclined-plane, and any fixing needn't be arranged, and the height of column is regulated also simple, easy to use.
