Description

Technical Field

[0001] This utility model relates to the field of horizontal cylinder technology, specifically a horizontal cylinder with a positioning and docking structure. Background Technology

[0002] A horizontal tank is a type of tank that lies on the ground. It is generally composed of a straight section and two sets of end caps. By adding a filter assembly inside the horizontal tank, the liquid passing through the tank can be filtered, thereby purifying the liquid.

[0003] When filtering liquids, the liquid can be poured into a horizontal tank and purified by passing through multiple sets of filter components. When installing existing horizontal tanks, the two end caps and the straight section in the middle need to be joined together by hand lay-up. This method is inefficient, adds an extra joint, and also causes the tank body to be not straight enough. Utility Model Content

[0004] The purpose of this invention is to provide a horizontal cylinder with a positioning and docking structure to solve the problem mentioned in the background art that existing horizontal cylinders are not convenient to assemble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a horizontal cylinder with a positioning and docking structure, comprising: a straight passage and a positioning mechanism, wherein one end of the straight passage is fixedly connected to a sealing head a, and the other end of the straight passage is provided with a sealing head b.

[0006] A positioning mechanism is provided at one end of the straight passage near the end cap b. The positioning mechanism includes a fixing block a fixedly connected to one side of the end cap b. A positioning block is fixedly connected to one side of the fixing block a. The fixing block b is connected through the outside of the positioning block. A limiting mechanism is provided on one side of the positioning mechanism. The limiting mechanism includes a connecting block fixedly connected to one side of the straight passage. A threaded rod is movably connected inside the connecting block through a bearing. One end of the threaded rod is threadedly connected to a pressing block.

[0007] Preferably, a sealing sleeve is fixedly connected to one side of the end cap a, and the outer side of the sealing sleeve is connected to the straight passage through a rubber ring. One side of the fixing block a is wedge-shaped.

[0008] Preferably, one end of the positioning block is conical, and multiple sets of protrusions are fixedly connected to the outer side of the positioning block, the protrusions being made of rubber.

[0009] Preferably, the fixing block b has a groove inside that matches the protrusion, and one side of the fixing block b is fixed to the straight passage.

[0010] Preferably, a spring is fixedly connected to one side of the fixed block b, one end of the spring is connected to a connecting plate, and both sides of the connecting plate are movably connected to the straight through via a rotating shaft.

[0011] Preferably, a wedge block a is fixedly connected to one end of the connecting plate, a wedge block b is fixedly connected to the end of the connecting plate away from the wedge block a, and a limit rod is slidably connected inside the extrusion block.

[0012] Preferably, one end of the limiting rod is fixed to the connecting block, and the number of positioning mechanisms and limiting mechanisms in the straight passage is not less than three, and the positioning mechanisms and limiting mechanisms are distributed at equal angles about the central axis of the straight passage.

[0013] Compared with existing technologies, the advantages of this horizontal cylinder with a positioning and docking structure are as follows: When the horizontal cylinder with a positioning and docking structure is closed, the straight passage and the end cap b are positioned by the positioning mechanism. Then, multiple sets of threaded rods can be rotated to drive the extrusion block through threaded transmission, thereby driving the extrusion block to move. When the extrusion block moves, it slides on the outside of the limiting rod, thereby limiting the position. When the inclined surface of one side of the extrusion block contacts the inclined surface of the wedge block b, the wedge block b, the connecting plate, and the wedge block a will all rotate. The wedge block a will then squeeze the fixed block a, causing the fixed block a to drive the end cap b on one side to fit tightly against the straight passage, thus completing the limiting and sealing of the straight passage and the end cap b. In this way, the horizontal cylinder can be easily positioned, docked, and sealed. Attached Figure Description

[0021] A positioning mechanism 5 is provided at one end of the straight passage 1 near the end cap b3. The positioning mechanism 5 includes a fixing block a501 fixedly connected to one side of the end cap b3. A positioning block 503 is fixedly connected to one side of the fixing block a501. A fixing block b502 is connected through the outside of the positioning block 503. A limiting mechanism 6 is provided on one side of the positioning mechanism 5. The limiting mechanism 6 includes a connecting block 601 fixedly connected to one side of the straight passage 1. A threaded rod 602 is movably connected inside the connecting block 601 through a bearing. A pressing block 603 is threadedly connected to one end of the threaded rod 602.

[0022] A sealing sleeve 4 is fixedly connected to one side of the end cap a2. The outer side of the sealing sleeve 4 is connected to the straight passage 1 via a rubber ring. One side of the fixing block a501 is wedge-shaped. One end of the positioning block 503 is conical. Multiple sets of protrusions 504, made of rubber, are fixedly connected to the outer side of the positioning block 503. The fixing block b502 has a groove 505 inside that matches the protrusion 504. One side of the fixing block b502 is fixed to the straight passage 1. The fixing block b502 has a positioning hole inside that matches the positioning block 503. The positioning block 503 and the fixing block b502 form a sliding structure. A spring 607 is fixedly connected to one side of the fixing block b502. One end of the spring 607 is connected to a connecting plate 605. The two sides of the connecting plate 605 are connected by a rotating... The shaft is movably connected to the straight passage 1; one end of the connecting plate 605 is fixedly connected to a wedge block a606, and the other end of the connecting plate 605 away from the wedge block a606 is fixedly connected to a wedge block b608; the inside of the extrusion block 603 is slidably connected to a limit rod 604; one end of the limit rod 604 is fixed to the connecting block 601; the number of positioning mechanisms 5 and limit mechanisms 6 in the straight passage 1 is not less than three sets, and the positioning mechanisms 5 and limit mechanisms 6 are distributed at equal angles about the central axis of the straight passage 1; the connecting plate 605 forms a rotating structure with the straight passage 1 through a rotating shaft; the extrusion block 603 and the threaded rod 602 form a threaded transmission structure; the inside of the extrusion block 603 is provided with a through groove that matches the limit rod 604; the limit rod 604 and the extrusion block 603 form a sliding structure.

[0023] In practical implementation, when the horizontal cylinder with positioning and docking structure is closed, the straight passage 1 is welded and fixed to the end cap a2 at one end. Then, the positioning block 503 on one side of the end cap b3 is docked with the fixing block b502 at one end of the straight passage 1. The conical positioning block 503 can more easily enter the positioning hole inside the fixing block b502, thus making it easier to complete the positioning and docking of the straight passage 1 and the end cap b3. When the protrusion 504 on the outside of the positioning block 503 contacts the groove 505 inside the fixing block b502, they will engage, completing the pre-fixation of the straight passage 1 and the end cap b3. Then, multiple sets of threaded rods 602 can be rotated and extruded. The pressure block 603 is driven by a threaded drive, which drives the extrusion block 603 to move. When the extrusion block 603 moves, it slides on the outside of the limiting rod 604 to limit the movement. When the inclined surface of one side of the extrusion block 603 contacts the inclined surface of the wedge block b608, the wedge block b608, the connecting plate 605 and the wedge block a606 will all rotate. The wedge block a606 will then press the fixing block a501, causing the fixing block a501 to drive the end cap b3 on one side to fit tightly against the straight passage 1, thus completing the limiting and sealing of the straight passage 1 and the end cap b3. In this way, the horizontal cylinder can be easily positioned and connected and sealed.

[0024] In summary: When using a horizontal cylinder with a positioning and docking structure, the straight tube 1 and the end cap a2 are first welded and fixed. Then, the straight tube 1 and the end cap b3 are fixed by the limiting mechanism 6 to complete the assembly of the horizontal cylinder.
