Description

Technical Field

[0001] The utility model relates to the technical field of bicycles, in particular to a pipe clamp for off-road bicycles. Background Art

[0002] Off-road bicycles, usually referred to as BMX bicycles, are a type of bicycle sport that emerged in the United States in the mid-to-late 1970s. The full name of BMX is BICYCLE MOTOCROSS, which means bicycle off-road. The body of this type of bicycle is generally made of alloy and can withstand the impact of falling from a height of several meters. There are many special features in the design of BMX bicycles, such as the handlebars can rotate 360 ​​degrees, and there are "bazookas" on the front and rear wheels for foot use. BMX bicycles are used in various occasions and forms, including mud racing competitions, mud jumping competitions, street competitions, half-pipe competitions, and flat-land fancy competitions.

[0003] The seat tube and the center tube of the frame of an off-road bicycle are connected by a seat tube clamp, so the seat tube clamp is a key component of the overall connection of the bicycle seat tube. The existing seat tube clamp is usually a clamp body, a screw rod is inserted at one end of the clamp body, and the clamp body is locked by a nut ring at one end to achieve the purpose of pre-fixation, and then the handle at the other end of the screw rod is rotated to squeeze the clamp body from the connection to achieve the purpose of tightening. After this fixation, the handle is subjected to a reaction force, and it is very difficult to rotate and open, and it is inconvenient to disassemble. Therefore, the utility model proposes an off-road bicycle pipe clamp to solve the problems existing in the prior art. Utility Model Content

[0004] In view of the above problems, the utility model proposes an off-road bicycle pipe clamp. The off-road bicycle pipe clamp only needs to rotate a two-way screw rod to drive the nut tubes at both ends to move relative to each other, so that the two sets of jacking arms rotate relative to each other, thereby pushing out the notch and lifting the top pad. The top pad can lift the handle, making it convenient to apply force and easier to open the handle.

[0005] To achieve the purpose of the utility model, the utility model is implemented by the following technical scheme: an off-road bicycle pipe clamp, comprising a clamp sleeve and a clamp seat, both ends of the clamp sleeve are provided with clamp seats, and screw rods are movably inserted into the inner sides of two groups of the clamp seats, one end of the screw rod is threadedly installed with a nut sleeve, and the other end of the screw rod is rotatably provided with a handle;

[0006] A mounting block is provided on the rear side of the jacket, and an inner cavity is provided at one end of the mounting block, a two-way screw rod is rotatably provided inside the inner cavity, and the upper end of the two-way screw rod extends out of the mounting block, nut tubes are threadedly installed on both ends of the two-way screw rod, one side of two groups of the nut tubes are hinged with jacking arms, one side of the mounting block is provided with a slot connected to the inner cavity, and one side of the two groups of the jacking arms are hinged with a top pad and extend out of the slot.

[0007] A further improvement is that a mounting groove is provided at one end of the handle, and a rotating shaft is rotatably provided inside the mounting groove, and one end of the screw rod is connected to the rotating shaft.

[0008] A further improvement is that a gasket is provided at the outer end of the clamp seat at one end, and the gasket is used to support the rotating end of the handle.

[0009] A further improvement is that a rubber ring is provided on the inner side of the jacket, and a plurality of groups of rubber rings are provided at equal distances.

[0010] A further improvement is that the jacket and the clamp seat are integrally formed, the handle is arc-shaped, and the inner curvature of the handle fits the outer curvature of the jacket.

[0011] A further improvement is that a knob is provided on the top of the screw rod, and the knob is integrally formed with the screw rod.

[0012] A further improvement is that a first hinge seat is provided on one side of the nut tube, a second hinge seat is provided on one side of the top pad, and both sides of the jacking arm are respectively hinged to the first hinge seat and the second hinge seat.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model fixes the seat tube of the bicycle through a clamping sleeve, and the clamping seat is clamped by rotating the nut sleeve and pulling the screw rod. The handle is rotated to fit one side of the clamping sleeve to achieve the purpose of tightening. When disassembling, it is only necessary to rotate the two-way screw rod to drive the nut tubes at both ends to move relatively, so that the two sets of jacking arms rotate relatively, thereby ejecting the notch and lifting the top pad. The top pad can lift the handle, making it convenient to apply force and easier to open the handle.

[0015] 2. The utility model arranges multiple groups of rubber rings on the inner side of the clamp to increase the friction force on the inner side, so that the clamp can clamp and fix the seat tube of the bicycle more firmly and is not easy to loosen and rotate. BRIEF DESCRIPTION OF THE DRAWINGS
