Fastening device for sport equipment

Abstract

The invention discloses a fastening device for sport equipment. The fastening device for the sport equipment comprises a rotary disc, the rotary disc is rotatably arranged on a support, a swing rod isarranged at the top of the rotary disc, a drive gear is arranged on the edge position of the bottom of the rotary disc, the drive gear is engaged with a bevel gear on the support, and an outer clamping plate and an inner clamping plate are arranged on lower part of the support. According to the fastening device for the sport equipment, a locking mechanism on the outer clamping plate is firstly released, a plate part is preliminarily clamped and taken by using the elastic force of a spring, then an optimal clamping force is obtained by slowly squeezing the spring, the situation that the platepart falls due to the insufficient clamping force or the surface of the plate part is sunken due to the fact that the clamping force is too strong is avoided, the processes of fastening and dismounting of the fastening device are both convenient, fast and easy to operate, the fastening device is basically suitable for clamping work between any two plate-shaped structures, the condition that the clamping device is not matched with the plate part is avoided, and the plate part is protected and buffered to some extent.

Description

technical field [0001] The invention relates to an auxiliary device for sports equipment, in particular to a fastening device for sports equipment. Background technique [0002] In sports competitions or teaching, it is often necessary to clamp score boards or rule cards, promotional boards and other similar plate-shaped components on the background board. Generally, traditional spring clips are used for clamping. This method often has different sizes. In case of matching, for example, insufficient clamping force causes the working board to fall, and when the clamping force of the spring clip is too large, it is easy to cause a small area of ​​depression on the surface of the background board, and the depression will further cause cracks on the entire background board, affecting its use or even In order to prevent this from happening, some users often choose to drill through holes between the background board and the working board with an electric drill, and then connect the...

[0002] In sports competitions or teaching, it is often necessary to clamp score boards or rule cards, promotional boards and other similar plate-shaped components on the background board. Generally, traditional spring clips are used for clamping. This method often has different sizes. In case of matching, for example, insufficient clamping force causes the working board to fall, and when the clamping force of the spring clip is too large, it is easy to cause a small area of ​​depression on the surface of the background board, and the depression will further cause cracks on the entire background board, affecting its use or even In order to prevent this from happening, some users often choose to drill through holes between the background board and the working board with an electric drill, and then connect them with iron wires. This method affects the appearance on the one hand, and the process is cumbersome and inconvenient to replace ;

[0003] Patent No. CN201810423747 discloses a teaching and demonstration device for space design. The device places the items to be displayed between two splints, releases the two push rods, and restores the original shape by compressing the spring, so that the two splints hold the items. Tight, in order to display items, when the exhibit needs to be raised and rotated, turn the rocker, the transmission shaft drives the second bevel gear and the first bevel gear to rotate in turn, and the lock nut drives the transmission screw to spiral up, this device is conducive to improving Demonstrate the stability of the item, avoiding the reduction of the demonstration effect due to unstable fixation; but the device has the following disadvantages: first, it still cannot solve the problem of clamping force adjustment, and the fastening effect is completely related to the elastic coefficient of the spring; secondly, the device The device is not suitable for clamping structures such as scoreboards, and is not suitable for installation on boards due to its volume and structure
