Detailed Description
In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1-5, a bicycle seat post locking member comprises a stand pipe 1 on a frame, a seat pipe 2 inserted in the stand pipe 1, and a screw rod 3 axially and rotatably arranged in the stand pipe 1, wherein the screw rod 3 is symmetrically and threadedly connected with positioning seats 4 driven to keep relative movement;
the two positioning bases 4 are closed to fold the clamping arc plates 5 to hold the base pipe 2.
Specifically, the clamping arc plate 5 in the above embodiment is provided with corresponding tenon-and-mortise mating pieces, and the two positioning seats 4 are closed, which means that the tenon-and-mortise mating pieces inevitably have wedge-shaped structures, and the wedge-shaped structures belong to the common technical knowledge of the skilled person, and are not expanded in detail.
Among the above-mentioned technical scheme, thereby utilize two positioning seats 4 of screw rod 3 drive to draw close the extrusion and make two centre gripping arc boards 5 staple bolts fix on riser 1, the fixed of seat pipe 2 and riser 1 is located the body and is gone on inside, avoids external erosion. And the clamping arc plate 5 and the seat tube 2 are also designed with corresponding concave-convex embedded designs, so that the fixing effect after installation is greatly improved.
Further, as can be seen from fig. 3 and 2, the positioning seat 4 in the above embodiment is specifically a truncated cone-shaped structure, and the cross section thereof is a polygonal structure, and the lower bottom of the positioning seat 4 is a hollow structure, and the inner wall of the hollow structure inside is consistent with the shape. And the clamping structure is arranged on the clamping arc plate 5, and the outer wall of the clamping arc plate is tangent to the inner wall of the hollow structure. In particular, the so-called snap-fit structure, i.e. the abutment block 53, the combination of the abutment blocks 53 on the two closed clamping arc plates 5 is consistent with the hollow structure. And the so-called polygonal structure may be a quadrangle, a hexagon, a heptagon, etc.
In the above embodiment, the elastic member 51, i.e. the spring or the elastic sheet, is disposed between the two clamping arc plates 5, and the outer wall of the clamping structure is abutted against the inner wall of the hollow structure by the driving of the elastic member 51. Therefore, when the screw rod 3 is driven to rotate, the two positioning seats 4 are drawn close to the center, so that the butt-joint block 53 is extruded, and the two clamping arc plates 5 are closed and hooped on the seat tube 2.
Further, as shown in fig. 2, a bore hole is formed in the side wall of the seat tube 2, and an inner hexagonal nut 6 is disposed at an end of the screw rod 3 located in the bore hole. The internal hexagonal nut 6 can be driven by an external hexagonal wrench to prevent other people from maliciously damaging.
In the above embodiment, as can be seen from fig. 2, slots 11 are symmetrically formed on the seat pipe 2, and when the seat pipe 2 is inserted into the vertical pipe 1, the screw rods 3 are located in the slots 11. Thereby avoiding the screw 3 so that the seat tube 2 can slide.
As can be seen from fig. 4 and 5, in the above embodiment, the outer wall of the seat tube 2 is symmetrically provided with the butt-joint grooves 21 distributed in a linear array, the outer wall of the adjacent side of the two clamping arc plates 5 is provided with the protrusions 52 distributed in a linear array, and the protrusions 52 are clamped in the butt-joint grooves 21 so that the two clamping arc plates 5 that are closed together fix the seat tube 2. And the clamping arc plate 5 and the seat tube 2 are also designed with corresponding concave-convex embedded designs, so that the fixing effect after installation is greatly improved.
Furthermore, the two sides of the butt-joint groove 21 are respectively provided with an inclined slope 22, and the inclined slopes 22 are used for guiding the protrusion 51 to slide into the butt-joint groove 21. In brief, when the clamping arc plates 5 are closed, the protrusions 52 correspond to the butt-joint grooves 21 or the inclined slopes 22, and when the screw 3 is driven to rotate, the two positioning seats 4 are drawn close to the center to extrude the butt-joint blocks 53, so that the two clamping arc plates 5 are closed and hooped on the seat pipe 2, and the protrusions 52 are not directly embedded into the butt-joint grooves 21, and are not slid into the butt-joint grooves 21 along the inclined slopes 22 to be fixed.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the utility model.
