Description

Technical Field

[0001] This utility model relates to the field of hook technology, specifically a tableside hook that can rotate freely. Background Technology

[0002] In crowded classroom environments, students' desks are usually limited in space, resulting in a lack of effective places to put their bags, water bottles, umbrellas, and other items. These items are often left lying around on the floor or tabletops, which not only takes up desk space and affects the cleanliness of the environment, but also easily causes passage obstruction.

[0003] In this situation, installing tableside hooks on the edge of the desk has become a common solution, as it can effectively utilize the side space of the desk and facilitate the hanging and fixing of items.

[0004] like Figure 4 It is a commonly used tableside hook with an adjustment mechanism (thread) integrated into the hook's hanging rod. By rotating the hook, it can be fixed to the side of the table.

[0005] However, in practical applications, we have found that although the above-mentioned hook has a simple structure, it also has obvious defects:

[0006] Because the hooks mentioned above are fixed by threads on the hanging rod, it is difficult to ensure that the hooks always face outwards when used to fix tabletops of different thicknesses. Furthermore, the hooks cannot be freely adjusted to ensure optimal fixing. This means that when not in use, the hooks are not easy to tuck inwards, and with many students moving around in the classroom, unused hooks always facing outwards can easily snag clothes, cause injuries to legs, or scratch hands.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] Please see Figures 1-4 A tableside hook that can rotate freely, its main body being a U-shaped plate 1, such as Figure 2 As shown, the U-shaped board 1 consists of two horizontal boards arranged one above the other and a vertical board for connecting the two horizontal boards, and is used to fit onto the side of the table.

[0032] like Figure 2 As shown, a lifting block 3 is installed between the two horizontal plates, which can move up and down. By setting the adjustable lifting block 3, it can adapt to table edges of different thicknesses, clamping them firmly without damaging the tabletop.

[0033] In this embodiment, elastic pads 4 are also fixedly installed on the top of the lifting block 3 and the bottom of the upper horizontal plate to prevent slipping and protect the tabletop.

[0034] In addition, side blocks 2 are fixedly connected to both ends of the lower horizontal plate. The two side blocks 2 and the vertical plate of the U-shaped plate 1 form a moving space for the lifting block 3 to move. This can limit the rotation of the lifting block 3, ensure accurate guidance during the lifting adjustment process, and prevent skewing and jamming.

[0035] In this embodiment, a screw groove is provided at the bottom of the lifting block 3, and a threaded rod 5 is screwed into the screw groove. The threaded rod 5 passes through and is rotatably installed on the lower horizontal plate of the U-shaped plate 1, and a knob 6 is fixedly connected to the bottom end. Thus, by turning the knob 6, the lifting block 3 can be driven to move up and down through the threaded rod 5.

[0036] In this utility model, the hanging rod 7 with a hook 8 at the bottom is movably inserted into the horizontal plate below the U-shaped plate 1, such as... Figure 2 As shown, a polygonal prism 9 is fixedly connected to the top of the hanging rod 7, and a groove 10 corresponding to the polygonal prism 9 is opened on the lower horizontal plate of the U-shaped plate 1. Specifically, the polygonal prism 9 is a hexagonal prism, and the groove 10 is a hexagonal prism groove.

[0037] By setting a polygonal prism 9 at the top of the hanging rod 7 and cooperating with the corresponding recess 10 on the horizontal plate below, the hook 8 can be accurately positioned and freely switched in multiple directions. This not only makes it easy to hang outwards when in use, but also allows it to be rotated inwards for storage when not in use, effectively reducing safety hazards such as bumps and snagging.

[0038] In this embodiment, the adjustment of the lifting block 3 and the rotation of the hook 8 are independent of each other and do not affect each other, thus avoiding the problem of "inability to adjust orientation" in the prior art.

[0039] Example 2:

[0040] Please see Figure 3 Based on Embodiment 1, in this embodiment, the hanging rod 7 and hooks 8 are provided in two sets, and each hook 8 has a contact surface 11 at its end, with a locking hole 12 on the contact surface 11. When the two sets of hooks 8 rotate to form a locking hole, the hooks can be locked together. Figure 3 When in the state shown, the lock can be passed through the keyhole 12 and locked, thus enabling the items hung on the hook 8 to have a certain anti-theft function, which is especially suitable for public scenes such as campuses.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
