[0003] At present, the prior art, authorization announcement number CN19508685U discloses a quick connector, which can prevent the No. 2 bucket shaft from detaching from the fixed jaws by arranging an anti-detachment mechanism at the opening of the fixed jaws when in use, thereby preventing the configuration accessories from falling off when the hydraulic cylinder or the supporting connecting rod fails and cannot support the hook-shaped pressure block, causing the movable jaws to be stuck on the No. 1 bucket shaft, effectively avoiding safety accidents and hidden dangers that may be caused by the falling off of the configuration accessories.

[0004] Although the above technical solution can prevent the anti-slip mechanism on the bucket shaft from falling off, the contact between the hydraulic lock and the bucket shaft is limited to one point when the hydraulic lock is extended, which will cause the hydraulic lock to be under too much pressure and unable to be unlocked after bending, or directly break and cause the bucket shaft to fall off.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] like Figure 1 as well as Figure 2 As shown, it is a schematic diagram of a connector structure of a preferred embodiment of the utility model. The connector of this embodiment includes a connector body 100, one side of the connector body 100 is fixedly connected with a fixed jaw 102, a hydraulic cylinder 103 is installed inside the connector body 100, the base of the hydraulic cylinder 103 is fixedly connected with a second rotating shaft body 105, the second rotating shaft body 105 is rotatably connected to the connector body 100, the telescopic end of the second rotating shaft body 105 is fixedly connected with a first rotating shaft body 104, the first rotating shaft body 104 is rotatably connected to the connector body 100, the outer wall of the first rotating shaft body 104 is rotatably connected with a movable jaw 101, and the first rotating shaft body 104 is rotatably connected to the connector body 100 at the same time. In this embodiment, the movable jaw 101 is opened and closed by telescoping the hydraulic cylinder 103 to cooperate with the adaptive rotation of the second rotating shaft body 105 and the first rotating shaft body 104, so that the bucket shaft can be stuck inside the movable jaw 101.

[0030] like Figure 3 as well as Figure 6 As shown, it is in this embodiment Figure 2 The enlarged structural diagram at A in the middle and the schematic diagram of the limit block structure, the connector body 100 is provided with a moving groove 107 at the bottom of the opening of the fixed tiger mouth 102, the inner wall of the moving groove 107 close to the outside is provided with an insertion groove 106 connected to the outside, the moving groove 107 is provided with inner grooves 108 on both sides of the insertion groove 106, the inner sides of the moving groove 107 are plugged with limit blocks 109, the outer wall of the limit block 109 is fixedly connected with a protruding block 111, and the protruding block 111 is stuck in the inside of the limit blocks 109 on both sides. In this embodiment, When in use, the bucket shaft is clamped inside the fixed jaws 102, and the limit blocks 109 on both sides are inserted into the insertion grooves 106 in turn and moved left and right respectively. The bottom of the limit block 109 contacts the outer wall of the bucket shaft, and the bucket shaft moves outward due to gravity to clamp the limit block 109, thereby achieving the purpose of fixing the bucket shaft. By setting the limit blocks 109 on both sides, the contact area with the bucket shaft can be increased, thereby increasing the fixing force of the bucket shaft, and the force of the bucket shaft can be distributed to the connector body 100 and the limit block 109, making the fixation more secure.

[0031] like Figure 4 as well as Figure 5As shown, it is a schematic diagram of the second threaded hole structure and a schematic diagram of the limit block and the fixing bolt limit structure in this embodiment. A second threaded hole 115 is provided at the inner top of the movable groove 107. The internal thread of the second threaded hole 115 is connected with a fixing bolt 114. The threaded end of the fixing bolt 114 is located between the limit blocks 109 on both sides. In this embodiment, the fixing bolt 114 is inserted between the limit blocks 109 on both sides to prevent the limit blocks 109 on both sides from moving toward the middle and falling off from the inside of the insertion groove 106 during use, so that the fixing effect of the bucket shaft can be better.

[0032] It is worth noting that the above-mentioned fixing bolt 114 and the second threaded hole 115 are the limiting components in this embodiment, and the limiting components include but are not limited to the fixing bolt 114 and the second threaded hole 115. As long as it is a component that can limit the limiting blocks 109 on both sides so that they cannot move to the middle, it can be applied to this embodiment.

[0033] like Figure 6 As shown, in order to make the contact area between the limit block 109 and the bucket shaft larger, in this embodiment, the limit blocks 109 on both sides are provided with a fitting arc surface 110 close to the outer wall of the bucket shaft. The fitting arc surface 110 fits with the outer wall of the bucket shaft when fixing the bucket shaft, thereby further increasing the fixing effect of the bucket shaft.

[0034] like Figure 7 As shown, it is a schematic diagram of the connection structure of the limit blocks on both sides in this embodiment. A sliding plate 112 is provided at the bottom of the limit blocks 109 on both sides. The sliding plate 112 is detachably connected to the bottom of the limit blocks 109 on both sides by screws. A first threaded hole 113 is provided at the upper end of the sliding plate 112. The fixing bolt 114 is threadedly connected to the first threaded hole 113 at the same time during installation. In this embodiment, the sliding plate 112 is fixed by the fixing bolt 114 so that it supports the limit blocks 109 on both sides. The sliding plate 112 is fixed to the bottom of the limit blocks 109 by screws and threadedly connected to the bottom of the limit blocks 109, which can prevent the limit blocks 109 on both sides from moving toward the middle, and the fixing bolt 114 can still prevent the limit blocks 109 on both sides from moving toward the middle.

[0035] To summarize, the specific use of this embodiment is as follows: during installation, first insert the bucket shaft into the fixed jaws 102, then insert the limit blocks 109 on both sides into the insertion groove 106 in turn and move them left and right respectively, and fit the outer wall of the bucket shaft with the fitting arc surface 110 to increase the contact area with the bucket shaft, then rotate the fixing bolt 114 from the top of the inner groove 108 and insert it between the limit blocks 109 on both sides, so that the gap between the limit blocks 109 on both sides can be filled and the limit blocks 109 on both sides can be moved to the middle, and then the sliding plate 112 is connected to the bottom of the limit blocks 109 on both sides by screws, thereby completing the fixation of the bucket shaft.
