Technical Field

[0001] The utility model relates to the technical field of cargo forks, in particular to a cargo fork and a forklift using the cargo fork. Background Art

[0002] A forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. The International Organization for Standardization I SO / TC110 calls it an industrial vehicle. It is often used for the transportation of large objects in storage, usually powered by a fuel engine or battery. The fork of a forklift is the most commonly used picking device for a forklift and is also one of the most important tools of a forklift. The fork is generally composed of two sections, the horizontal section is the working part for forking and placing goods, and the vertical section is the supporting part. The forklift can stack and transfer goods through the fork. The material and size of the fork will vary according to different needs and uses.

[0003] Common forks can refer to the utility model patent document with authorization announcement number CN215479510U, which discloses a fork hook for improving the strength of the fork, which includes two fork bodies, an upper hook and a lower hook. The fork body includes a vertical part and a horizontal part, and a reinforcing rib plate is installed between the bending parts of the vertical part and the horizontal part through an installation structure.

[0004] When the fork is in use, the two fork bodies are used to fork the goods and move them to a position at a specified height. However, when a lot of goods are placed on the fork body, there is often a problem: due to the heavy weight of the goods, the fork body is not easy to be pulled out from under the goods, and it is easy to drive the goods to move outward for a distance, resulting in misplacement. After the fork body is pulled out, the staff is required to straighten the moved goods into place. Utility Model Content

[0005] The utility model provides a cargo fork to solve the technical problem in the prior art that the cargo fork is easy to cause the cargo to move when the cargo is pulled out, resulting in the cargo not being placed in place; the utility model also aims to provide a forklift using the cargo fork.

[0006] In order to solve the above problems, the fork provided by the utility model adopts the following technical solutions:

[0007] A fork comprises a vertically extending support frame and at least two transversely extending fork bodies, wherein the fork bodies are arranged in parallel in the width direction of the support frame, and further comprises:

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0036] It should be noted that the main idea of ​​the present invention is that, by adding a sliding sleeve 4, when the fork body 3 places the goods in place, the fork body 3 moves outwards, and under the action of the gravity of the goods, the fork body 3 does not directly drive the goods to move outwards, but the fork body 3 and the sliding sleeve 4 move relative to each other, so that the goods are relatively displaced with the fork body 3 without moving, and the space occupied by the goods on the fork body 3 becomes smaller. At this time, pulling the fork body 3 outwards again can more conveniently pull out the fork body 3, while reducing the distance the goods move outwards, thereby improving the phenomenon of the goods not being placed in place in the prior art, and solving the technical problem that the fork is easy to cause the goods to be displaced when pulling out the goods, resulting in the goods not being placed in place.

[0037] After introducing the basic principle of the utility model, various non-limiting embodiments of the utility model are specifically introduced below. Any number of elements in the drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0038] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0039] Embodiment 1 of the fork provided by the utility model:

[0040] like Figures 1 to 6 As shown, the fork 1 includes a vertically extending support frame 2 and three transversely extending fork bodies 3. The three fork bodies 3 are arranged in parallel in the width direction of the support frame 2. On this basis, it also includes an additional sliding sleeve 4. The number of the sliding sleeve 4 is the same as the fork body 3. Each fork body 3 is slidably sleeved with a sliding sleeve 4, and each sliding sleeve 4 is connected to the support frame 2 through a telescopic member 5. The function of the sliding sleeve 4 is to move synchronously with the cargo for a distance when the fork body 3 is pulled out of the cargo, so as to shorten the distance that the cargo is taken out by the fork body 3.

[0041] The sliding sleeve 4 is described in detail below. The sliding sleeve 4 is composed of two sections, including an inner tube 6 and an outer tube 7. The outer tube 7 is slidably mounted on the inner tube 6, and the inner tube 6 has an anti-dropout portion on the outside to prevent the outer tube 7 from falling out. The inner tube 6 is connected to the support frame 2 through a telescopic member 5.

[0042] The two-section sliding sleeve 4 further extends the distance of relative displacement between the sliding sleeve 4 and the fork body 3, thereby further reducing the space occupied by the goods on the fork body 3 after sliding, and reducing the distance the goods move outward when the fork body 3 is withdrawn. Specifically, the anti-slip portion is a protrusion welded on the outer periphery of the inner tube 6.

[0043] About the material of the sliding sleeve 4. The sliding sleeve 4 is a metal tube. This is because metal tubes are widely available and easy to process, collect and use.

[0044] In this embodiment, the telescopic member 5 is a chain, and both the sliding sleeve 4 and the support frame 2 have a pull nose 8, and the two ends of the chain are respectively mounted on the sliding sleeve 4 and the pull nose 8 of the support frame 2.

[0045] In this embodiment, the length of the telescopic member 5 meets the requirement of pulling the sliding sleeve 4 to the root of the fork body 3. That is, in the initial position, the sliding sleeve 4 can be pulled to the position of the root of the fork body 3.

[0046] In order to facilitate the use of the fork 1, the utility model is also used in conjunction with a cargo carrying plate 9, which has the function of initially carrying the cargo. The cargo carrying plate 9 is provided with three slots 10 arranged at intervals to adapt to the three fork bodies 3 of the fork 1. When the fork 1 is used, the three fork bodies 3 can be directly inserted into the slots 10 to lift the cargo on the cargo carrying plate 9 for transportation. Figure 6 , wherein the direction indicated by the arrow is the direction in which the fork body 3 is inserted.

[0047] The working principle of the cargo fork provided by the utility model is as follows: in the initial state, the cargo is stacked on the cargo carrying plate 9, and when the cargo fork 1 is working, the three cargo fork bodies 3 extend into the three slots 10 of the cargo carrying plate 9 to lift the cargo away. When the cargo fork is in place, the cargo fork body 3 moves outwards. Under the action of the gravity of the cargo, the cargo fork body 3 does not directly drive the cargo to move outwards, but the cargo fork body 3 and the sliding sleeve 4 move relative to each other, so that the cargo is relatively displaced with the cargo fork body 3 without moving, and the space occupied by the cargo on the cargo fork body 3 becomes smaller. At this time, the cargo fork body 3 is pulled outwards again, so that the cargo fork body 3 can be pulled out more conveniently, and at the same time, the distance that the cargo moves outwards is reduced, thereby improving the phenomenon that the cargo is not properly placed in the prior art.

[0048] Embodiment 2 of the fork provided by the utility model:

[0049] The main difference between it and Example 1 is:

[0050] In Example 1, the fork includes a vertically extending support frame and three transversely extending fork bodies.
