The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a telescopic link of quick adjustment length, includes female pole to and the sub-pole of suit in female pole, be provided with the annular bead that a plurality of equidistance were arranged in the female pole, sub-pole top evenly is provided with is no less than two stationary blades, the stationary blade top is provided with the arc chimb that corresponds annular bead, sub-pole lateral surface with the laminating of annular bead.
Preferably, the female rod and the male rod are two sleeved round tubes, and the cross section of the annular convex rib is semicircular.
Preferably, four fixing pieces are evenly arranged at the top of the sub-rod, and U-shaped grooves corresponding to the fixing pieces are formed in the top of the sub-rod.
Preferably, the stationary blade cross-section is the P font, and is concrete, the stationary blade top surface is plane portion, the plane portion both sides are provided with chamfer portion, arc chimb bottom surface be with the cambered surface of annular bead adaptation, arc chimb side is the convex arc face of connecting chamfer portion and arc chimb bottom surface respectively.
Preferably, the bottom of the sub-rod is provided with a sealing plate.
This application theory of operation as follows, through the relative position who adjusts female pole and son pole, the length to the telescopic link is adjusted, equidistance annular bead on the female pole inside wall is used for fixing the position of son pole in female pole, the length that makes the telescopic link be applicable to user's use custom and user demand, be provided with the stationary blade that corresponds annular bead on the son pole, through mutually supporting of arc chimb on the stationary blade and annular bead, realize good fixity ability, the arc chimb still is provided with the plane portion and the chamfer portion that correspond semicircular annular bead, the length adjustment that makes the telescopic link is more swift and convenient.
The utility model has the advantages that: the utility model adjusts the length of the telescopic rod by adjusting the relative position of the main rod and the sub rod, so that the length of the telescopic rod is suitable for the use habit and the use requirement of a user; through mutually supporting of arc chimb on the stationary blade and annular bead, realize good fixity ability, the arc chimb still is provided with the plane portion and the chamfer portion that correspond semicircular annular bead, makes the length adjustment of telescopic link more swift convenient.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is one of the schematic cross-sectional structural diagrams of the present invention;
fig. 2 is a second schematic cross-sectional view of the present invention;
fig. 3 is an enlarged view of fig. 2 at the circled position.
Detailed Description
Referring to fig. 1 to 3, a telescopic link of quick adjustment length, including female pole 1 to and the sub-pole 2 of suit in female pole 1, be provided with the annular bead 11 that a plurality of equidistance were arranged in female pole 1, 2 tops of sub-pole evenly are provided with and are no less than two stationary blades 21, stationary blade 21 top is provided with the arc chimb 3 that corresponds annular bead 11, 2 lateral surfaces of sub-pole with the laminating of annular bead 11, through mutually supporting of arc chimb 3 at stationary blade 21 top and annular bead 11, the relative position of fixed female pole 1 and sub-pole 2 to adjust the length of telescopic link.
Preferably, the female rod 1 and the sub-rod 2 are two sleeved round tubes, the cross section of the annular convex edge 11 is semicircular, and the length of the telescopic rod is adjusted more labor-saving.
Preferably, 2 tops of sub-pole are evenly provided with four stationary blades 21, 2 tops of sub-pole are provided with U type groove 22 between the corresponding stationary blade 21, make stationary blade 21 bottom be connected with 2 arcs of sub-pole, in the use, need the sub-pole 2 of pull to reach the purpose of adjusting length, and U type groove 22 can strengthen stationary blade 21 and sub-pole 2's connection performance, avoids stationary blade 21 fracture in the use.
Preferably, the cross-section of stationary blade 21 is the P font, the top surface of stationary blade 21 is plane portion 23, plane portion 23 both sides are provided with chamfer portion 24, 3 bottom surfaces of arc chimb be with the cambered surface of 11 adaptations of annular bead, in the assembling process, but 3 buckles of arc chimb are on annular bead 11, and easy operation realizes good fixity ability, 3 sides of arc chimb are the cambered surface of connecting chamfer portion 24 and 3 bottom surfaces of arc chimb respectively, make the length adjustment of telescopic link more swift and convenient.
