Description

Curtain rod

Technical Field

The utility model relates to a curtain support piece technical field, concretely relates to curtain rod.

Background

The curtain rod is a cross rod used for hanging the curtain, the whole curtain rod is cylindrical, the materials mainly comprise metal and wood, the noise can be reduced by installing the curtain, direct sunlight is avoided, and privacy is protected.

The traditional curtain rod is specially customized before installation, firstly, measurement is carried out according to the size of a window, then the length of the curtain rod is matched, and the curtain rod is generally a whole. When a longer curtain rod needs to be used, the transportation of the curtain rod is very inconvenient due to the limited sizes of the elevator and the corridor, and different rooms need to be matched with the curtain rods with different lengths, so that the use is troublesome, and the use experience of a user is reduced.

SUMMERY OF THE UTILITY MODEL

In view of the above analysis, the present invention provides a curtain rod to solve the deficiencies of the prior art.

The utility model discloses mainly realize through following technical scheme:

the utility model provides a pair of curtain rod, including the connecting rod, be responsible for and the telescopic link, be responsible for and locate the both ends of connecting rod relatively, the outer end of being responsible for is located relatively to the telescopic link, the both ends of connecting rod have connecting portion respectively, the connecting rod epirelief is equipped with the first spacing portion that is located between two connecting portions, the inner pot head of being responsible for leans on with first spacing portion counterbalance on locating connecting portion to with the connecting portion tight fit, the outer end movable sleeve of being responsible for is located on the telescopic link, the inner of telescopic link is fixed with conical screw, movable mounting has the inflation cover on the conical screw, the inflation cover activity is located in the main pipe.

Through setting up curtain pole components of a whole that can function independently, the connecting rod cup joints with the person in charge, conveniently assemble, through set up inflation cover and conical screw between being responsible for and the telescopic link, pull out the main suitable length outside of tubes with the telescopic link during use, through rotatory telescopic link, because inflation cover outer wall and the inner wall looks mutual friction of being responsible for, make the inflation cover along conical screw syntropy rotatory and to the direction that its diameter becomes big removal, conical screw extrusion inflation cover inner wall simultaneously, inflation cover outer wall and the inner wall tight fit of being responsible for, realize fixing between them, be convenient for adjust the length of telescopic link, easy dismounting, can match the needs of different window widths, do not need to customize very much, it is more convenient to use.

Furthermore, a plurality of limiting protrusions are arranged on the connecting portion at intervals, and the limiting protrusions are in interference fit with the inner end of the main pipe. In order to increase and be responsible for the friction of inner wall, carry out the outrigger to being responsible for, both interference fit avoid taking place the pine to take off.

Preferably, the edge of the connecting part is provided with a guide inclined plane. When being responsible for and installing with the connecting rod, the direction inclined plane plays the effect of direction, is convenient for install. Wherein, the guide inclined plane is connected with the limiting bulge.

Furthermore, the outer end of the main pipe is sleeved with a transition ring which is a conical surface, and the transition ring is movably sleeved on the telescopic rod. When the link on the (window) curtain slides on the (window) curtain pole, the effect of direction is played to the transition ring, and the conical surface design makes the back and forth slip of link more in the same direction as smooth, and when the telescopic link was rotatory to and was responsible for the activity, the transition ring played spacing effect to the expansion sleeve, avoided its outer end from being responsible for to be unscrewed. During assembly, the expansion sleeve is sleeved on the conical screw, the outer end of the telescopic rod is sleeved from the inner end of the main pipe, the outer end of the telescopic rod extends out of the transition ring, then the length of the telescopic rod is adjusted to be proper, and the telescopic rod and the main pipe are fixed in a rotating mode.

Further, still include with telescopic link demountable assembly's bracket, be equipped with the constant head tank on the bracket, the telescopic link cooperation is located in the constant head tank. The curtain rod is conveniently and stably fixed on the wall surface through the bracket.

Furthermore, the outer end of the telescopic rod is detachably provided with a decorative head. The decoration head can be replaced according to the requirement to adapt to the requirements of different users, and the decoration effect is attractive.

Furthermore, an elastic gasket is arranged between the positioning groove and the telescopic rod. Because telescopic link and bracket are the metal material, when the joint, both are fixed firm inadequately, through setting up the elastic gasket, can make the tighter of telescopic link and bracket assembly card, be difficult to take place relative displacement, wherein the elastic gasket is the plastics material.

Furthermore, the decoration head is sleeved on the outer end of the telescopic rod.

Furthermore, a connecting piece is fixed at the outer end of the telescopic rod, an external thread is arranged on the connecting piece, and an internal thread matched and connected with the external thread is arranged in the decorative head. Make the simple to operate and firm of telescopic link and finial, be difficult to drop. Wherein, the connecting piece is made of plastic materials.

Furthermore, the outer wall of the expansion sleeve is provided with a gap which runs through the inner wall and two ends along the length direction of the outer wall so as to form two opposite and movable adjusting ends. Through making it form two free ends that can open or close together, for the deformation of inflation cover provides the space, avoid the excessive extrusion deformation of breach connection root of inflation cover, improve the life of inflation cover.

Furthermore, the inner end of the telescopic rod is sleeved on the fixed end of the conical screw rod and is riveted and fixed with the conical screw rod. The installation is convenient, and the looseness is not easy to happen.

Furthermore, a second limiting part is convexly arranged at the free end of the conical screw, and an opening which is movably matched with the second limiting part is arranged on the expansion sleeve.

The expansion sleeve compressed by the main pipe is limited on the conical screw through the second limiting part, so that the phenomenon that the expansion sleeve and the conical screw are separated in the main pipe is avoided from being excessively rotated reversely.

Compared with the prior art the utility model discloses technical scheme's beneficial effect does:

the utility model provides a curtain rod conveniently assembles and transports, can adjust the length of telescopic link, easy dismounting, and the user can match the needs of different window widths and freely adjust, does not need to customize very much, and it is more convenient to use, promotes user's use and experiences.
