In order to overcome the defects of the prior art, the utility model provides a sleeve fixing structure with compact structure, convenient installation and stability.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a firm sleeve pipe fixed knot constructs, includes the sleeve pipe, sheathed tube one side is provided with the casing, and the opposite side is provided with down the casing, go up casing and casing fixed connection down form with the chamber that holds that the sleeve pipe matches, sheathed tube one end nestification is in hold the intracavity, shells inner wall both sides all are provided with the arch down, the sleeve pipe be provided with the recess of protruding adaptation, the sleeve pipe is equipped with the through-hole, go up the casing be provided with the last fixing base that the through-hole corresponds, it is provided with the through-hole to go up the fixing base, down the casing be provided with the lower fixing base that the through-hole corresponds, the fixing base is.
Preferably, a sliding groove is arranged in the sleeve.
The upper shell and the lower shell are fixedly connected through a plurality of locking screws.
Preferably, the sleeve is an aluminum profile.
Preferably, the upper housing is further provided with an upper stopper, and the lower housing is further provided with a lower stopper.
The utility model has the advantages that: the utility model has the advantages of compact structure and reasonable design, it is fixed through the removal installation of the three-dimensional direction of restriction cover, utilize the casing to hoop with screw locking in order to reach the steadiness between the reinforcing accessory down, make the sleeve pipe more resistance.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
