The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 3, in some embodiments, a positioning element is made of an elastic material, and includes a body, where a plurality of protruding structures 3 are disposed on the body in a lattice distribution; the bulge structure 3 bulges from the inner side to the outer side of the body so as to form a cavity on the inner side of the body and a bulge on the outer side; the inner side of the body is provided with a bulge for connection. Specifically, the whole setting element that is used for pressing from both sides and arranges in between the major possession pole and the minor possession pole that the telescopic link cup jointed each other, the internal face of setting element has can with the binding face 1 of the outer wall 2 laminating of minor possession pole mutually, be provided with on the internal face of setting element to be used for with the arch 4 of minor possession pole buckle connection. The position of the protrusions 4 is staggered with respect to the ridge structure 3.

The positioning member of some embodiments is integrally formed of a plastic material. The protrusion structure 3 is formed by protruding the wall of the positioning member to the outside, i.e. a concave area (cavity) is correspondingly formed on the back of the protrusion structure 3, so that the protrusion structure 3 has better deformation capability. The plurality of ridge structures 3 distributed in a lattice form enclose a rectangle (as shown in fig. 3) or a diamond (as shown in fig. 4). In the present embodiment, the specific number and shape of the ridge structures 3 are not limited.

In order to maximize the contact area of the ridge structure 3 with the inner wall of the large segment. Referring to fig. 5, the top surface 31 of the bump structure 3 is a cylindrical surface, and the shape of the top surface matches with the shape of the inner wall surface of the large-pitch rod, so that a larger contact area can be provided, which is beneficial to increase the friction force. In some embodiments, the top surface 31 of the bump structure 3 is a spherical surface, which has a smaller contact area with the inner wall surface of the large rod than a cylindrical surface, so that the friction is smaller and the telescopic rod is pulled more smoothly. Of course, in some embodiments, in order to consider both the positioning effect with large friction and the smooth effect when the telescopic rod is pulled, in the plurality of bump structures, the top surface of one portion of the bump structures is a spherical surface, the top surface of the other portion of the bump structures is a cylindrical surface, and the bump structures with the spherical top surfaces and the bump structures with the cylindrical top surfaces are preferably arranged in a staggered manner.

The bottom of the inner wall surface of the positioning piece is provided with a flange 5 for abutting against the end surface of the bottom end of the small-section rod so as to prevent the positioning piece from separating from the small-section rod.

Some embodiments also provide a telescopic rod, the telescopic rod comprises a plurality of sections of rod joints which are sequentially sleeved from outside to inside, the larger diameter of two adjacent rods is a large rod, the smaller diameter is a small rod, the positioning piece is clamped between the large rod and the small rod, the bottom end of the small rod is provided with a fixing hole, and the bulge 4 of the positioning piece is clamped in the fixing hole; the binding surface 1 of the positioning piece is bound with the outer wall surface 2 of the small-section rod, and the plurality of bulge structures 3 are propped against the inner wall surface of the large-section rod.

Specifically, two positioning pieces are clamped between the large section rod and the small section rod, and the two positioning pieces are symmetrically arranged on the outer wall surface 2 of the small section rod. It is easy to understand that only one positioning member with a notch and a cylindrical structure can be arranged.

Because the whole locating piece is made by elastic material, and the hump structure 3 is bulged outwards from the inboard of body to make the hump structure 3 form independent elastic supporting point, a plurality of independent elastic supporting points can be formed to a plurality of hump structures 3, and a plurality of elastic supporting points can provide stable lasting elastic supporting power, even single supporting point damage (for example, fatigue, production defect etc.) can not produce big influence to whole. The existence of a plurality of bump structures 3 makes the setting element clamp arrange in the telescopic link and cup joint between the major segment pole and the minor segment pole between, can be for a long time stable support between major segment pole and minor segment pole, realizes the permanent positioning function of stabilizing, and the support ability is difficult for the decay.

Simultaneously, because a plurality of uplift structures 3 are the dot matrix distribution, so realized the multiple spot contact between setting element and the big festival pole, not only make the setting element even with the distribution of atress between the big festival pole, avoid the telescopic link to rock, moreover, suitable increase the frictional force between setting element and the big festival pole, strengthened the steadiness when the telescopic link is fixed in a certain position.

It is thus clear that the setting element of this embodiment can make the telescopic link realize firm locate function to setting element simple structure, material cost is low, only needs can realize the installation of setting element with the setting element joint on the little section pole, and the installation is convenient.

Referring to fig. 6, a second positioning member is further provided in some embodiments, which is different from the above embodiments in that the plurality of raised structures of the outer wall surface 2 of the positioning member of the present embodiment form a ring shape.

It can be seen from the combination of these embodiments that no matter what shape the lattice ridge structures 3 enclose, as long as a plurality of ridge structures 3 are dispersed on the outer wall surface 2, sufficient friction force between the positioning member and the large rod can be ensured, and the stress is uniform, thereby achieving the effect of enhancing the stability of the telescopic rod.

Referring to fig. 7, a third positioning member is provided in some embodiments, which is different from the above embodiments in that the top surfaces 31 of the plurality of raised structures 3 of the outer wall surface 2 of the positioning member are flat.

When the inner wall surface of the large-section rod is a plane, two side edges of the top surface of the raised structure 3 are in contact with the inner wall surface of the large-section rod, and the middle area of the top surface 31 of the raised structure 3 is not in contact with the inner wall surface of the large-section rod. The quantity of the bump structures 3 is enough to ensure that under the premise of ensuring the friction force, the contact area between the single bump structure 3 and the inner wall surface of the large section rod is reduced, so that a larger deformation space can be provided for the single bump structure 3, the telescopic rod can be stretched smoothly when the telescopic rod is stretched, and meanwhile, the stability of the telescopic rod after stretching is ensured.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
