Description

Technical Field

[0001] The utility model relates to the technical field of fish tanks, in particular to an L-shaped negative pressure fish tank. Background Art

[0002] A negative pressure fish tank is a fish tank that achieves top vacuum and maintains low pressure through a unique design, solving the height limitation problem of traditional fish tanks. It uses the negative pressure principle to raise the water level, making it easy to operate and ensuring the survival of fish.

[0003] The existing L-shaped negative pressure fish tank is usually composed of an upright fish tank and an inverted fish tank. A large L-shaped negative pressure fish tank can increase the height of the inverted fish tank so that the fish inside can swim in the "high altitude", which has good ornamental value. However, due to its irregular shape, the large L-shaped negative pressure fish tank has many limitations such as inconvenient transportation and large storage space. Therefore, in view of the above problems, we propose a new type of L-shaped negative pressure fish tank. Utility Model Content

[0004] The utility model aims to solve the problems of large L-shaped negative pressure fish tanks in the prior art, such as irregular shapes, inconvenient transportation, large storage space and other limitations, and proposes an L-shaped negative pressure fish tank.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an L-shaped negative pressure fish tank, including a bottom cylinder, a connecting edge is arranged at the top of the bottom cylinder near the left side, a first sealing ring is arranged at the top of the bottom cylinder, a baffle is arranged at the top of the first sealing ring, and one-way meshing teeth are arranged on the inner surface walls around the baffle, a vertical cylinder is inserted between the inner surface walls of the connecting edge, and rubber meshing teeth are arranged on the outer surface of the vertical cylinder near the bottom, and the rubber meshing teeth and the one-way meshing teeth are in one-way meshing connection.

[0006] Preferably, a raised edge is provided at a position near the right side of the top of the bottom cylinder, and a left surface of the raised edge is connected to a right surface of the connecting edge.

[0007] Preferably, a support ring is fixed between the inner surface walls of the connecting edges and close to the bottom, and a second sealing ring is provided on the top of the support ring.

[0008] Preferably, a third sealing ring is provided at the bottom of the vertical cylinder, and the third sealing ring fits tightly with the bottom of the second sealing ring.

[0009] Preferably, positioning posts are provided at the top of the connecting edge near the four corners, and the outer surface of the positioning posts slides through the outer surface of the first sealing ring and extends upward.

[0010] Preferably, mounting holes are provided through the top of the enclosure near the four corners, and the outer surface of the positioning column and the inner surface wall of the mounting hole are slidably fitted.

[0011] Preferably, a nut is threadedly connected to the outer surface of the positioning column near the top, and the bottom of the nut is in conflict with the bottom of the enclosure.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, two fish tanks with regular appearance can be obtained after the vertical cylinder and the bottom cylinder are separated. When installing and using, it is only necessary to insert the vertical cylinder into the inner side of the connecting edge at the top of the bottom cylinder. At this time, the supporting ring plays a role of supporting the vertical cylinder, and the rubber meshing teeth on the surface of the vertical cylinder will be deformed after being squeezed by the one-way meshing teeth on the inner wall of the enclosure. After the vertical cylinder is fully inserted, the shape of the rubber meshing teeth will be restored and one-way meshing connection will be formed with the one-way meshing teeth, thereby completing the connection between the vertical cylinder and the bottom cylinder and forming a large L-shaped negative pressure fish tank. During the entire installation process, it is only necessary to insert the vertical cylinder into the connecting edge and press downward. The split design allows the large L-shaped fish tank to be transported or stored after being split, and can be quickly spliced ​​and installed when in use, thereby greatly improving practicality.

[0014] 2. In the utility model, the fixing of the enclosure can be released by rotating the four nuts to remove them from the top of the positioning column. At this time, the one-way meshing teeth and the rubber meshing teeth will lose the one-way meshing relationship. Then, the enclosure is pulled upward, and the one-way meshing teeth on the inner wall of the enclosure squeeze the rubber meshing teeth and deform them, so that the enclosure moves to the top of the rubber meshing teeth until it is detached from the surface of the vertical cylinder. Then, the vertical cylinder is pulled out upward to separate the bottom cylinder and the vertical cylinder. The overall disassembly and assembly are convenient, which reduces the difficulty of transferring large L-shaped negative pressure fish tanks. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides an L-shaped negative pressure fish tank, including a bottom cylinder 1, a connecting edge 2 is arranged at the top of the bottom cylinder 1 near the left side, a first sealing ring 3 is arranged at the top of the bottom cylinder 1, a baffle 31 is arranged on the top of the first sealing ring 3, and one-way meshing teeth 33 are arranged on the inner surface walls around the baffle 31, a vertical cylinder 5 is inserted between the inner surface walls of the connecting edge 2, a rubber meshing tooth 51 is arranged on the outer surface of the vertical cylinder 5 near the bottom, and the rubber meshing tooth 51 and the one-way meshing tooth 33 are connected in one-way meshing, a heightened edge 11 is arranged at the top of the bottom cylinder 1 near the right side, and the left surface of the heightened edge 11 is connected to the right surface of the connecting edge 2, a supporting ring 4 is fixed between the inner surface walls of the connecting edge 2 near the bottom, a second sealing ring 41 is arranged on the top of the supporting ring 4, and a third sealing ring 52 is arranged at the bottom of the vertical cylinder 5, and the third sealing ring 52 and the bottom of the second sealing ring 41 are tightly fitted.

[0024] The effect achieved by the entire embodiment 1 is that when the device is installed and used, by placing the bottom cylinder 1 in a suitable position, and then inserting the vertical cylinder 5 into the connecting edge 2 with the opening facing downward, the support ring 4 in the connecting edge 2 can provide good support for the vertical cylinder 5, and the second sealing ring 41 and the third sealing ring 52 at the top of the connecting edge 2 and the bottom of the vertical cylinder 5 can ensure the sealing between the vertical cylinder 5 and the bottom cylinder 1. At the same time, during the process of inserting the vertical cylinder 5 into the interior of the connecting edge 2, the rubber meshing teeth 51 on its surface will be squeezed and deformed by the one-way meshing teeth 33 on the inner wall of the aluminum alloy enclosure 31. When the vertical cylinder 5 is fully inserted, the rubber meshing teeth 51 will restore the deformation and mesh with the one-way meshing teeth 33 in one direction, thereby completing the vertical cylinder 5. The cylinder 5 and the bottom cylinder 1 are connected to form an L-shaped negative pressure fish tank. At this time, it is only necessary to fill water into the bottom cylinder 1 and extract the air in the vertical cylinder 5 to form a vacuum state. At the same time, under the action of the rubber meshing teeth 51, the sealing between the surface of the vertical cylinder 5 and the enclosure 31 is good. During the entire installation process, it is only necessary to insert the vertical cylinder 5 into the connecting edge 2 and press downward. The split design allows large L-shaped fish tanks to be transported or stored after being split, and can be quickly spliced ​​and installed when used, and the practicality is greatly improved. The heightened edge 11 is mainly used to increase the maximum height of the liquid level in the bottom cylinder 1, and the first sealing ring 3 is provided to mainly improve the sealing between the enclosure 31 and the connecting edge 2.

[0025] Embodiment 2, as Figure 1-Figure 5 As shown, positioning columns 21 are provided at the top of the connecting edge 2 near the four corners, and the outer surface of the positioning column 21 slides through the outer surface of the first sealing ring 3 and extends upward. Mounting holes 32 are penetrated at the top of the enclosure 31 near the four corners. The outer surface of the positioning column 21 and the inner surface wall of the mounting hole 32 are slidably fitted, and a nut 22 is threadedly connected to the outer surface of the positioning column 21 near the top, and the bottom of the nut 22 conflicts with the bottom of the enclosure 31.

[0026] The effect achieved by the entire embodiment 2 is that, when the device needs to be transported and moved, it is only necessary to rotate the four nuts 22 to remove them from the top of the positioning column 21 to release the fixation of the enclosure 31. At this time, the one-way meshing teeth 33 and the rubber meshing teeth 51 will lose the one-way meshing relationship, and then the enclosure 31 is pulled upward, and the one-way meshing teeth 33 on the inner wall of the enclosure 31 will squeeze the rubber meshing teeth 51 and deform them so that the enclosure 31 moves to the top of the rubber meshing teeth 51 until it is detached from the surface of the vertical cylinder 5, and then the vertical cylinder 5 is pulled upward to separate the bottom cylinder 1 and the vertical cylinder 5. The overall disassembly and assembly is convenient, which reduces the difficulty of transferring large L-shaped negative pressure fish tanks.

[0027] Working principle: When installing and using the device, the bottom cylinder 1 is placed in a suitable position, and then the vertical cylinder 5 is inserted into the connecting edge 2 with the opening facing downward. The supporting ring 4 in the connecting edge 2 can provide good supporting force for the vertical cylinder 5, and the second sealing ring 41 and the third sealing ring 52 at the top of the connecting edge 2 and the bottom of the vertical cylinder 5 can ensure the sealing between the vertical cylinder 5 and the bottom cylinder 1 after they are tightly fitted. At the same time, during the process of inserting the vertical cylinder 5 into the interior of the connecting edge 2, the rubber meshing teeth 51 on its surface will be squeezed and deformed by the one-way meshing teeth 33 on the inner wall of the aluminum alloy enclosure 31. When the vertical cylinder 5 is fully inserted, the rubber meshing teeth 51 will restore the deformation and mesh with the one-way meshing teeth 33 in one way, thereby completing the connection between the vertical cylinder 5 and the bottom cylinder 1 and forming an L-shaped negative pressure fish tank. At this time, it is only necessary to fill the bottom cylinder 1 with water and extract the air in the vertical cylinder 5 to form a vacuum state. At the same time, under the action of the rubber meshing teeth 51, The sealing between the surface of the vertical cylinder 5 and the enclosure 31 is good. During the entire installation process, it is only necessary to insert the vertical cylinder 5 into the connecting edge 2 and press it downward. The split design allows large L-shaped fish tanks to be transported or stored after being split, and can be quickly assembled and installed when in use, which greatly improves practicality. In addition, when it is necessary to transport and move the device, it is only necessary to rotate the four nuts 22 to remove it from the top of the positioning column 21 to release the fixation of the enclosure 31. At this time, the one-way meshing teeth 33 and the rubber meshing teeth 51 will lose the one-way meshing relationship, and then the enclosure 31 will be pulled upward. The one-way meshing teeth 33 on the inner wall of the enclosure 31 will squeeze the rubber meshing teeth 51 and deform to move the enclosure 31 to the top of the rubber meshing teeth 51 until it is detached from the surface of the vertical cylinder 5, and then the vertical cylinder 5 can be pulled out upward to separate the bottom cylinder 1 and the vertical cylinder 5. The overall disassembly and assembly are convenient, which reduces the difficulty of transferring large L-shaped negative pressure fish tanks.
