Example one

As shown in fig. 1 to 9, the telescopic rod comprises a fixed rod 1, a movable rod 2, a locking base 3, a pressing base 4 and a locking snap ring 5, wherein the fixed rod 1 is hollow and has at least one open end, and the locking base 3 is arranged at one open end of the fixed rod 1; under the locking state, at least part movable rod 2 runs through locking base member 3 and movably inserts and establish in dead lever 1, and 5 covers of locking snap ring are established on movable rod 2, and at least part card of locking snap ring 5 establishes between locking base member 3 and movable rod 2, compresses tightly 4 detachably of base member and fixes on locking base member 3.

The fixed rod 1 is a tubular structure which is hollow inside and is provided with an opening at least at one end, the movable rod 2 is also a tubular structure, and the outer diameter of the movable rod 2 is smaller than the inner diameter of the fixed rod 1; when only one end of the fixed rod 1 is opened, the locking base body 3 is arranged at the end of the fixed rod 1 with the opening, the locking base body 3 is hollow and has a structure with two opened ends, and the outer diameter of the movable rod 2 is also smaller than the inner diameter of the locking base body 3; at least one part of the movable rod 2 penetrates through the locking base body 3 and is inserted into the fixed rod 1 and can move along the axial direction of the fixed rod; compress tightly base member 4 and locking snap ring 5 and all overlap and establish on dead lever 1, locking snap ring 5 only partly card is established between locking base member 3 and movable rod 2, compresses tightly base member 4 and still overlaps simultaneously on the partial position of locking snap ring 5 and locking base member 3, and compresses tightly base member 4 and can dismantle fixedly with locking base member 3. The specific operation of adjusting the total length of the telescopic rod is as follows: the pressing base body 4 is detached from the locking base body 3 (at the moment, the pressing base body 4 is sleeved on the movable rod 2 in particular); then, moving the locking clamp ring 5 to the direction far away from the locking base body 3, so that the locking clamp ring 5 is not clamped between the locking base body 3 and the movable rod 2, and the movable rod 2 can slide along the axis direction; the part of the movable rod 2 embedded in the fixed rod 1 is increased or decreased to shorten or increase the total length of the telescopic rod; after the length of the telescopic rod is adjusted, the locking clamping ring 5 is clamped between the movable rod 2 and the locking base body 3 again, and then the compression base body 4 is fixed on the locking base body 3.

The existing telescopic rod generally comprises a fixed rod, a movable rod, a nut and a screw, wherein an external thread is arranged on the fixed rod, a threaded hole is formed in the side wall of the nut, the movable rod is inserted into the fixed rod, the nut is sleeved at the joint of the fixed rod and the movable rod and is in threaded connection with the external thread on the fixed rod, the screw penetrates through the nut and is screwed, and one end of the screw abuts against the movable rod to relatively fix the movable rod and the fixed rod; when the length needs to be adjusted, the screw and the screw cap need to be unscrewed firstly, and then the screw cap and the screw cap are screwed in sequence after the adjustment is completed. The telescopic link of this kind of structure, the screw is not hard up easily in the use, causes the length of telescopic link to change easily, influences the use of telescopic link. According to the technical scheme, the locking clamping ring 5 is embedded between the movable rod 2 and the locking base body 3, the movable rod 2 and the locking base body 3 are fixed through the locking clamping ring 5, the movable rod 2 is prevented from sliding relative to the fixed rod 1, and the telescopic rod is guaranteed not to change easily in use; in addition, during locking, it is fixed to compress tightly base member 4 and locking base member 3, overlaps simultaneously on locking snap ring 5, avoids locking snap ring 5 to drop, further guarantees that the telescopic link length can not change easily when using.

Further, as shown in fig. 3, 8 and 9, the locking snap ring 5 includes a collar 51 and a catching flap 52 provided on the collar 51, and the catching flap 52 is caught between the locking base 3 and the movable rod 2 in the locked state. The lantern ring 51 is of an annular structure, the diameter of the inner ring of the lantern ring 51 is larger than the outer diameter of the movable rod 2, and the width between the inner ring and the outer ring of the lantern ring 51 is larger than the distance between the locking base body 3 and the outer wall of the movable rod 2; a clamping flap 52 is arranged on the lantern ring 51 close to the inner ring of the lantern ring, and the thickness of the clamping flap 52 is equal to or slightly larger than the distance between the outer wall of the movable rod 2 and the inner wall of the locking base body 3; in the locked state, the lantern ring 51 is sleeved on the movable rod 2, and the clamping flap 52 is embedded in the gap between the locking base body 3 and the movable rod 2.

The hanging plate 7 is of a structure similar to a Chinese character 'ao', a first transverse folding portion 71, a first vertical portion 72, a second transverse folding portion 73, a second vertical portion 74 and a third transverse folding portion 75 are sequentially connected, the first vertical portion 72 is perpendicular to the first transverse folding portion 71, the upper end of the first transverse folding portion is connected with one end of the first transverse folding portion 71, the second transverse folding portion 73 is perpendicular to the first vertical portion 72, one end of the second transverse folding portion is connected with the lower end of the first vertical portion 72, the second vertical portion 74 is perpendicular to the second transverse folding portion 73, the lower end of the second transverse folding portion 73 is connected with the other end of the second transverse folding portion 73, the third transverse folding portion 75 is perpendicular to the second vertical portion 74, and one end of the third transverse folding portion 75 is connected with the upper end of the second vertical portion 74; therefore, the first transverse fold portion 71, the second transverse fold portion 73, and the third transverse fold portion 75 are parallel to each other, and the first vertical portion 72 and the second vertical portion 74 are parallel to each other. The first transverse folding portion 71 and the third transverse folding portion 75 are fixed on the installation surface by fixing members such as screws, the second transverse folding portion 73 is connected and fixed with one end of the movable rod 2 or one end of the fixed rod 1, specifically, a through hole is formed in the second transverse folding portion 73, and one end of the movable rod 2 or one end of the fixed rod 1 is inserted into the through hole. The structure of the hanging plate 7 is arranged, so that the lamp can be stably fixed on the installation surface, the opening at the end part of the movable rod 2 or the fixed rod 1 can be kept, and wiring is convenient.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
