[0002] In the field of mechanical processing and assembly technology, the most common locking method is the combination of bolts and nuts. This method requires manual use of a wrench to repeatedly rotate the bolts. Under working conditions where parts need to be frequently locked and released, it cannot achieve the purpose of fast operation. In addition, the bolts cannot generally be installed on the parts in advance. After the parts are disassembled, the bolts need to be stored separately, which can easily lead to loss. Secondly, the dead point principle can be used to design a locking mechanism, which can be designed and installed on the parts, but the dead point locking mechanism is generally large in size and is not convenient to use in some smaller installation planes and operating spaces.

[0019] Beneficial Effects

[0020] 1. A quick locking mechanism of the utility model has a cylindrical appearance, a small diameter and a small height. A small diameter mounting hole is designed on its outer flange, which can be installed on the plate to be locked in advance through a first connecting member. When locking, by pressing and rotating the handle, the eccentric clamping claw is rotated to press and fit with the mounting plate, and the elastic member provides elastic restoring force, so that the eccentric clamping claw has a tendency to retract relative to the mounting seat, and presses the mounting plate to fit with the plate to be locked to perform the locking operation. When loosening, press and reverse the handle again to rotate the eccentric clamping claw to stagger with the plate to be locked, and it can be released quickly. The mechanism has economy, safety, good operability, reliability and safety, environmental protection standards and requirements. Compared with the bolt and nut connection combination in the prior art, the locking mechanism has the above three advantages: first, the structure is simple and reliable, the operation is convenient and fast, the locking and releasing operations can be completed quickly, and the working efficiency of the locking mechanism is improved; second, the problem of possible loss of the locking tool is avoided; third, the size is small, the weight is light, and it is convenient to install and use in a small operating space.

[0021] 2. Due to the invisibility of the mounting base, the operator cannot intuitively judge the degree and trend of the rotation of the eccentric jaw. Therefore, the present application sets up a slider and a slide groove. On the one hand, it is not easy to slip during the pressing and rotating handle. On the other hand, it is convenient for personnel to perceive the adjustment position of the eccentric jaw, which increases convenience.

[0040] In actual operation, the first connecting member 13 can be used to install the eccentric clamping jaw 22 on the plate A to be locked in advance. When locking, the eccentric clamping jaw 22 is rotated to press and fit with the mounting plate B by pressing and rotating the handle 20.

The eccentric pin passes through the first locking hole A1 and the second locking hole B1, and is engaged with the bottom side of the second locking hole B1.

[0044] The locking clamp arm 21 includes a connecting block 210, a connecting arm 211 and a locking member 212. The connecting block 210 is annular and coaxially arranged in the cylinder cavity of the upper section 111 of the installation cylinder.

[0045] One end of the connecting arm 211 penetrates the installation tube 11 from bottom to top, and is plugged into the connecting block 210, and the other end of the connecting arm 211 is connected to the eccentric clamping claw 22;

[0046] The locking clamp arm 21 and the eccentric clamp claw 22 are made of 45# steel, and the mounting tube 11 is made of aluminum alloy. Therefore, although the locking clamp arm 21 and the eccentric clamp claw 22 have a certain strength, the overall weight of the device is relatively light.

[0047] The handle 20 passes through the first through hole 120 from top to bottom and is threadedly connected to the connecting arm 211;

[0048] The locking member 212 passes through the connecting block 210 and the connecting arm 211 in sequence in the radial direction, and cooperates with the handle 20 to limit the rotation or loosening of each other, and the locking member 212 and the installation tube 11 do not interfere with each other;

[0049] The locking piece 212 is a hexagon socket cone end set screw, and a second through hole is radially opened in the upper section 111 of the mounting tube. The connecting block 210 and the connecting arm 211 are radially opened with second threaded holes that are connected to each other. The second through hole is matched with the second threaded hole, and the hexagon socket cone end set screw passes through the second through hole and engages with the second threaded hole until one end of the hexagon socket cone end set screw is in conflict with the handle 20 and the other end is embedded in the connecting block 210, ensuring that the hexagon socket cone end set screw and the mounting tube 11 do not conflict with each other.

[0052] refer to Figure 3 , Figure 3 A schematic cross-sectional view of the connection between the connecting block and the mounting tube in an embodiment of the utility model is shown; it can be clearly seen from the schematic view that a slide groove 2101 is provided in the circumferential direction of the outer ring wall of the connecting block 210, and a slider 1110 is correspondingly protruded in the cylinder cavity of the upper section 111 of the mounting tube, and the slider 1110 and the slide groove 2101 form a sliding guide cooperation along the circumference of the connecting block 210.

[0053] Due to the invisibility of the mounting base 1, the operator cannot intuitively judge the degree and trend of rotation of the eccentric jaw 22. Therefore, the present application provides a slider 1110 and a slide groove 2101. On the one hand, it is not easy to slip during the process of pressing the rotating handle 20. On the other hand, it is convenient for personnel to perceive the adjustment position of the eccentric jaw 22, thereby increasing convenience.
