Description

Quick release structure

This creation belongs to the technical field of quick release for telescopic pipe fittings, specifically refers to a quick release structure that can confirm the locking and restrict the direction of quick release movement, so that it can not rotate up and down at will when operating the quick release, and The lock can only be operated at a limited position to reduce the problem of component damage, effectively extend its service life, and improve the convenience of operation.

In order to adjust the height of the seat cushion of the bicycle to suit the height of the rider, a bicycle is usually inserted with a cushion tube on the seat cushion vertical tube, and a quick release group is provided at the port of the seat cushion vertical tube for selective beam Tighten and relax the seat cushion tube for adjustment at any time according to demand. This structure can also be applied to the similar outer tube and inner tube telescopic fittings, so that the outer tube and inner tube can be selectively adjusted relative length or height; As shown in the first and second figures, the general quick-release assembly (20) is provided on the outer wall with a longitudinal slot (11) on the outer tube (10) [such as a seat cushion vertical tube] port for selective tightening of an inner The tube (15) [such as a seat cushion tube], the quick-release assembly (20) has a cradle (21) fixed to the outer edge of the port of the outer tube (10) and an eccentric wrench pivotally arranged on the cradle (21) It is composed of a piece (25), wherein both ends of the opening of the beam base (21) have opposite shaft blocks (22), and the two shaft blocks (22) have opposite mounting holes (23) on different outer sides, and Each of the mounting holes (23) has an engaging portion (230) inside, and the two ends of the opening of the eccentric wrench (25) respectively have shaft blocks (26) corresponding to the shaft blocks (22) of the beam seat (21), And the eccentric wrench (25) shaft block (26) points Do not have a relative mounting hole (27), and the mounting hole (27) has an engaging portion (270) inside for the use of a pivot rod (24) through the beam seat (21) and the eccentric wrench (25) the pressing pieces (28) between the shaft blocks (22, 26) on both sides, and each pressing piece (28) has two opposite turntables (281, 286), and each turntable (281, 286) 286) The different surfaces respectively have the clamping parts (282, 287) embedded in the shaft blocks (22, 26) of the beam base (21) and the eccentric wrench (25), and the turntables (281, 286) are opposite to the surfaces With oblique pushing edges (283, 288) respectively, the oblique pushing edges (283, 288) of the pressing member (28) relative to the turntables (281, 286) can be selectively pushed to the highest point or overlapped at the lowest point, When the eccentric wrench (25) is rotated, the shaft blocks (22) on both sides of the bundle base (21) can be selectively approached, so that the bundle base (21) can compress the outer tube (10) to compress the inner tube (15), allowing The outer tube (10) can selectively tighten or release the inner tube (15), and then adjust the relative position between the two according to requirements.

However, there is a big problem in the use of the aforementioned quick release structure, that is, when the eccentric wrench (25) is pressed tightly, there is no proper limiting effect, causing the eccentric wrench (25) to have an unknown lock The phenomenon of tight and random rotation affects the convenience of operation, and may also cause an excessively tight situation, which affects the smoothness of subsequent release. Furthermore, excessive friction damage may affect the future tightening effect, resulting in operation and use. The inconvenience and troubles of the above, and how to solve the aforementioned problems are currently expected by the industry and users.

The reason is that the creator is in-depth discussion of the problems faced by the aforementioned quick-release group when using it, and through years of research and development and manufacturing experience in related industries, actively seeking solutions, after continuous research and trial work, finally A quick release structure has been successfully developed, which can overcome the inconvenience caused by the inconvenience of operation due to the inability of limit confirmation.

Therefore, the purpose of this creation is to provide a quick release structure, so that the limit can be obtained when selectively tightened, and the lock can only be confirmed by operating at a limited position to achieve the lock.

In addition, another purpose of this creation is to provide a quick-release structure, which can effectively restrict it from turning up and down at will, reducing the problem of component damage, effectively extending its service life, and improving the convenience of operation.

According to this, the main purpose of this creation is to achieve the aforementioned objectives and effects through the following technical means: the quick-release assembly has a beam seat locked on the top of an outer tube and an eccentric wrench pivotally arranged on the beam seat It is composed of a retractable inner tube inserted into the outer tube; and the opposite ends of the opening of the bundle base are respectively provided with opposite shaft blocks for using a pivot rod to penetrate the shaft blocks provided on both sides of the bundle base ; And the eccentric wrench is U-shaped frame, and the two ends of the opening of the eccentric wrench have shaft blocks corresponding to the outer side of the shaft block of the beam seat, and the beam seat and the eccentric wrench on both sides of the shaft block A rotating pressing member is respectively arranged between the opposite surfaces, and each rotating pressing member has two opposite turntables, and each turntable can be respectively positioned by the chock shaft block or rotated by the eccentric wrench shaft block, and each turntable is opposite to the surface Each has an oblique pushing edge, and the eccentric wrench is provided with a corresponding limit protrusion on the opposite inner side of the adjacent shaft block, so that the eccentric wrench is pulled downward when the limit protrusion is pressed against the bottom edge of the beam seat When the position is limited, the oblique pushing edges of the turntables of the rotating pressing members overlap at the highest point.

Thus, through the display of the aforementioned technical means, the pipe quick release structure of the present invention can utilize the positioning effect of the limit projection of the eccentric wrench of the quick release group, and can obtain a signal when selectively tightened, knowing that it is in a limited position The operation lock has been reached, and the lock can be confirmed, effectively restricting it from turning freely up and down, reducing the problem of component damage, effectively extending its service life, and increasing The convenience of operation improves its practicability, thereby effectively enhancing its added value and enhancing its economic benefits.

In order to enable your review committee to further understand the composition, characteristics and other purposes of this creation, the following is a preferred embodiment of this creation, and the detailed description in conjunction with the drawings is as follows, while allowing those familiar with the technical field to follow this specification Specific implementation.
