Telescopic pipe quick release structure

The creative department belongs to a rapid tightening technology of a telescopic pipe fitting, and specifically refers to a quick-release structure of a telescopic pipe fitting which can increase the pressing stroke, thereby increasing the tightening force and improving the tightening reliability of the telescopic pipe fitting.

Pressing, the telescopic pipe is composed of an outer pipe and an inner pipe which can be slidably and selectively fixed in the outer pipe, and is mainly used for a place where the length or height needs to be adjusted at any time according to requirements, such as a bicycle frame vertical. The tube and the seat tube inserted in the interior, and in order to allow the seat tube to selectively fix the height, a quick-release structure for selectively generating a tightening action is usually arranged at the top of the vertical tube of the frame, and the seat tube is tightened according to requirements. For the purpose of quickly adjusting the height of the seat tube; The general quick release structure is composed of a C-shaped collar and an eccentric wrench. The eccentric wrench is disposed at the two ends of the C-shaped collar, and the design of the two ends of the opening can be changed by the lever to change the C shape. The inner diameter of the bundle ring allows the outer tube (frame standpipe) to selectively tighten or release the inner tube (seat tube), thereby adjusting the relative position between the two.

However, there is a big problem in the use of the quick-release structure, that is, the eccentric puller mainly uses the radius of the axial center and the top support edge to change its yoke when rotating, but when the eccentric radius is large, When the compression stroke is long, the tightening force can be increased, but it requires a large force to be pulled. The eccentric lever causes a problem of inconvenience in operation, and excessive force exerts damage to the parts. On the other hand, when the eccentric radius is small, although the operation is less labor-saving, the actuation compression stroke is shorter, and there is a problem of insufficient tightening, and it is easy to change the position during use of the telescopic pipe, such as the seat tube. The rider loses weight or vibration and shrinks into the standpipe, causing inconvenience and danger of use; In other words, the quick-release structure of the existing telescopic pipe fittings cannot simultaneously have the advantages of large tightening force and easy operation, resulting in inconvenience and trouble in operation and use, and how to solve the aforementioned problems is currently expected by the industry and users. .

In view of this, the creator is in-depth discussion on the problems faced by the above-mentioned quick-release structure, and actively seeks solutions through years of experience in R&D and manufacturing of related industries. After continuous efforts in research and trials, it has finally succeeded. Developed a quick-release structure for telescopic pipe fittings, which can overcome the inconvenience and trouble caused by the inability to combine the tightening force and the labor saving.

Therefore, the purpose of the present invention is to provide a quick release structure of the telescopic tube member, so that the actuation stroke can be increased under the same operating distance, and the tightening force can be effectively improved, thereby improving the reliability.

Moreover, another object of the present invention is to provide a quick release structure for a telescopic pipe member, which has the advantages of labor saving and easy operation, and can avoid damage of the component due to excessive force, thereby improving its practicability.

Accordingly, the present invention mainly achieves the foregoing objectives and effects through the following technical means: it is applied between an outer tube and an inner tube inserted in the outer tube, the quick release structure including at least one C shape a bundle ring, a U-shaped wrench frame and two pairs of fixed fixed blocks and brake blocks; The C-shaped collar is disposed at the top end of the outer tube, and the C-shaped collar has an opposite mounting portion respectively protruded from the two ends of the opening, and the U-shaped frame has two opposite side arms extending corresponding to the outer edge of the outer tube. And the free ends of the two sides of the arms respectively have a pair of mounting portions on the outside of the two mounting portions of the C-shaped collar; further, the fixed tooth blocks are respectively disposed on the mounting portion of the C-shaped collar and the U-shaped frame One side surface, and each of the fixed tooth blocks is formed with at least two equal-angled oblique teeth on one side surface of the U-shaped frame, each of the inclined teeth has a high point and a low point, respectively, and the foregoing braking The tooth block is disposed on the side of the mounting portion of the U-shaped frame relative to the C-shaped collar, and each of the braking blocks is formed with at least two equal angles on the side surface of the fixed tooth block, and the corresponding fixed block is obliquely pushed. The oblique teeth of the teeth, wherein each of the oblique teeth has a high point and a low point respectively, and the shaft assembly is pivoted to the U-shaped frame mounting portion, the brake tooth block, the fixed tooth block and the C-shaped collar Installation department.

Thereby, through the foregoing technical means, the quick-release structure on the outer tube of the telescopic pipe fitting of the present invention can change the pitch of the brake tooth block on the U-shaped frame by using the upper and lower pulling of the U-shaped frame. The point corresponds to the high point or the low point of the oblique tooth of the fixed tooth block on the C-shaped collar, and the purpose of tightening or releasing the inner tube is achieved, and since one action can be pressed by both sides, the action stroke is lengthened, which is effective The increased tightening force can improve the reliability of the fixing between the outer tube and the inner tube, and has the advantages of labor saving and easy operation, and can reduce the problem of component damage, effectively prolong the service life of the quick-release structure, and greatly improve the reliability. In order to effectively enhance its added value and enhance its economic efficiency.
