DETAILED DESCRIPTION

[0020] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0021] The accompanying drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0022] See also Figure 1-5 A forklift quick-install bucket structure includes a cargo fork 1 and a fork sleeve 2, a bucket body 3 rotatably connected to the outside of the fork sleeve 2, a support 4 arranged on the top of the fork sleeve 2, a cylinder 5 sleeved between the bucket body 3 and the support 4, and a first cross bar 6 and a second cross bar 7 arranged on the outside of the fork sleeve 2. A fixing sleeve 8 located on one side of the second cross bar 7 is arranged on the outside of the fork sleeve 2, and a locking mechanism 9 is sleeved inside the fixing sleeve 8.

[0023] Among them, four limiting columns 10 are arranged on the top of the second cross bar 7 , and the four limiting columns 10 are symmetrically distributed in groups of two on the top of the second cross bar 7 , and the outer diameter of the oil pipe of the oil cylinder 5 is greater than the distance between the two limiting columns 10 .

[0024] Among them, an observation port 11 located above the fixed sleeve 8 is opened at the top of the fork sleeve 2, through which the condition of the limit rod 91 inserted into the fork 1 can be observed, so as to confirm from the outside whether the limit rod 91 is completely inserted into the fork 1 and the fork sleeve 2.

[0025] The locking mechanism 9 includes a limit rod 91 movably sleeved inside the fork 1, the fork sleeve 2 and the fixed sleeve 8, a first spring 92 sleeved inside the fixed sleeve 8, and a first limit sleeve 93 threadedly sleeved on the outside of one end of the fixed sleeve 8. The limit rod 91 can be pushed to move inside the fixed sleeve 8 by the elastic force of the first spring 92, so that after the fork 1 is inserted into the fork sleeve 2, the limit rod 91 can be automatically inserted into the fork 1 by the elastic force of the first spring 92. The limit rod 91 is located at one end of the fixed sleeve 8. The inner sleeve is fixedly provided with a push rod 94 sleeved inside the fixed sleeve 8. The push rod 94 facilitates the pushing of the limit rod 91. When the friction between the limit rod 91 and the fork 1 is greater than the elastic force of the first spring 92, the limit rod 91 can be manually inserted into the fork 1 by the push rod 94. The push rod 94 is movably sleeved with a pull rod 95 inside, and the outer sleeve of one end of the pull rod 95 extending from the outside of the push rod 94 is clamped with a buckle 96, and the outer sleeve of the pull rod 95 is sleeved with a second spring 97 located between the push rod 94 and the buckle 96, and the outer sleeve of one end of the pull rod 95 extending from the outside of the buckle 96 is movably sleeved with a second limiting sleeve 98 arranged on the outer side of the fork sleeve 2. The push rod 94 can be limited by the cooperation of the pull rod 95 and the second limiting sleeve 98, so that the push rod 94 will not rotate, ensuring that the limiting rod 91 will not detach from the inside of the fork 1. At the same time, the elastic force of the second spring 97 will prevent the pull rod 95 from automatically detaching from the inside of the second limiting sleeve 98, and the pull rod 95 can be pulled to move it out of the inside of the second limiting sleeve 98, so that the push rod 94 can rotate 90 degrees to facilitate pushing the limiting rod 91.

[0026] Among them, a limiting groove 12 is provided inside the fixed sleeve 8, which is adapted to the push rod 94 and has a semicircular groove notch on the inner side. The limiting groove 12 can limit and guide the push rod 94 while allowing the limiting rod 91 to be separated from the inside of the fork 1. The push rod 94 is rotated 90 degrees so that it can be stuck in the inner side of the limiting groove 12 under the elastic force of the first spring 92, so as to facilitate the disassembly of the fork sleeve 2.

[0027] Among them, a circular hole 13 is set in the middle of the first limiting sleeve 93, and the fixing sleeve 8 can be discharged through the circular hole 13. Even if the external dust enters the interior of the fixing sleeve 8 through the limiting groove 12, the dust can be discharged to the outside of the fixing sleeve 8 through the circular hole 13 during the movement of the limiting rod 91, thereby preventing the dust from blocking the movement of the limiting rod 91.

[0028] When installing the bucket, Figure 3As shown in the figure, after the fork 1 is inserted into the fork sleeve 2, the push rod 94 is moved out from the semicircular notch of the limiting groove 12, and the push rod 94 is rotated 90 degrees to release the limit of the limit rod 91 by the push rod 94. At this time, the limit rod 91 is driven to move under the elastic force of the first spring 92, and the fork 1 is continuously pushed into the fork sleeve 2. In this process, the limit rod 91 is inserted into the fork 1 by the elastic force of the first spring 92, and whether the limit rod 91 is completely inserted into the fork sleeve 2 is observed through the observation port 11. If the interior of the fork 1 is not fully inserted, the limit rod 91 can be fully inserted into the interior of the fork 1 by manually pushing the push rod 94. After the limit rod 91 is fully inserted into the interior of the fork 1, pull the pull rod 95 by hand and rotate the push rod 94 90 degrees in the opposite direction, then release the pull rod 95. At this time, the pull rod 95 is inserted into the interior of the second limit sleeve 98 under the elastic force of the second spring 97 to complete the installation of the bucket.
