Description

Technical Field

[0001] This utility model belongs to the field of magnetic pump technology, and in particular relates to a quick-release magnetic pump head. Background Technology

[0002] A magnetic pump is a device that transmits torque without contact through a magnetic drive, thereby replacing dynamic seals with static seals to achieve a completely leak-free operation. It mainly consists of a pump head, a magnetic drive unit, and other components.

[0003] Chinese utility model patent CN221973788U discloses a quick-release magnetic pump head. By rotating a locking screw, the compression block presses against the locking post, causing the locking post to engage with the locking groove. This allows for quick disassembly of the pump head side cover, facilitating opening, inspection, and maintenance of the pump head without the need to tighten multiple bolts. Furthermore, by using a locking plate with a locking mechanism, along with a bottom plate and connecting plate through which a long screw passes, the stability of the pump head after installation on the mounting plate is improved, preventing loosening during prolonged use and ensuring stable operation of the quick-release magnetic pump head.

[0004] Based on research and practical experience in the production and assembly of magnetic pumps, some defects and shortcomings were found in the aforementioned comparative documents: the use of a snap-fit ​​method for pump head installation resulted in poor connection tightness, making fluid leakage prone to occur at the connection points, and the installation sealing was poor. Therefore, there is an urgent need to improve the existing quick-release magnetic pump head and provide a quick-release magnetic pump head with better sealing performance. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a quick-release magnetic pump head that is reasonably designed, simple in structure, easy to operate, tightly installed, and has better sealing performance, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-release magnetic pump head includes a magnetic pump body and a pump head mechanism. The bottom of the magnetic pump body is symmetrically fixed with a fixed support. A first fixed plate is fixedly sleeved on the outer side of one end of the magnetic pump body. Multiple positioning grooves are annularly formed inside the outer edge of the first fixed plate. The left end of the magnetic pump body is provided with the pump head mechanism. The right end of the pump head mechanism is fixed with a second fixed plate. Multiple sets of positioning and locking components are annularly installed on the outer right side of the second fixed plate. The multiple sets of positioning and locking components are arranged one-to-one with the multiple positioning grooves. A sealing gasket is embedded in the outer edge of the first fixed plate near the second fixed plate.

[0008] In a preferred embodiment, the first fixing plate and the second fixing plate have the same diameter and length, and the two are connected by multiple sets of positioning and locking components to form a disassembly structure.

[0009] In a preferred embodiment, the positioning groove includes an arc-shaped segment, a first circular hole portion, and a second circular hole portion. The first circular hole portion and the second circular hole portion are located at the two ends of the arc-shaped segment, and the arc-shaped segment, the first circular hole portion, and the second circular hole portion are interconnected.

[0010] In a preferred embodiment, the center of the arc segment coincides with the center of the first fixing plate, the diameter of the first circular hole and the second circular hole are equal and greater than the width of the arc segment, the thickness of the arc segment and the first circular hole are equal to the thickness of the first fixing plate, and the thickness of the second circular hole is only half the thickness of the first fixing plate.

[0011] In a preferred embodiment, the sealing gasket is located between the first fixing plate and the second fixing plate, and the sealing gasket is made of rubber.

[0012] In a preferred embodiment, the positioning and locking assembly includes a fixed screw, an anti-detachment disc, a movable sleeve, and an anti-slip ring. The fixed screw is fixedly installed on the outer wall of the second fixed plate near the first fixed plate. An anti-detachment disc is fixedly connected to the end of the fixed screw away from the second fixed plate. A movable sleeve is threaded on the outer side of the threaded section of the fixed screw. An anti-slip ring is adhesively fitted on the outer side of the movable sleeve near the anti-detachment disc. The anti-slip ring is made of rubber.

[0013] In a preferred embodiment, the diameter of the fixing screw is equal to the width of the arc segment, and the diameter of the movable sleeve is equal to the diameter of the first circular hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the solution of this utility model:

[0016] Align and insert the three sets of positioning and locking components with the first circular holes of the three positioning slots respectively. After the movable sleeve passes through the first circular hole, rotate the pump head mechanism clockwise. At this time, the fixing screw can enter the arc section and the movable sleeve can move to the second circular hole. Since the second circular hole is not a through design and the diameter of the movable sleeve is larger than the width of the arc section, it is convenient to perform preliminary positioning of the positioning and locking components and the pump head mechanism. The installation is convenient and the operation is simple.

[0017] Once the movable sleeve moves to the position of the second circular hole, it can be manually rotated to move away from the anti-detachment disc and insert into the second circular hole. The movable sleeve is controlled to engage with the first fixed plate through the second circular hole, thus completing the positioning and installation of the pump head mechanism. As the movable sleeve rotates, it continuously pulls the first and second fixed plates closer together, which can strongly compress the sealing gasket between them, effectively enhancing the sealing performance at the connection and preventing fluid leakage.

[0025] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0026] like Figure 1-4As shown, the quick-release magnetic pump head of this utility model includes a magnetic pump body 1 and a pump head mechanism 5. The bottom of the magnetic pump body 1 is symmetrically fixed with a fixed support 2. A first fixed plate 3 is fixedly sleeved on the outer side of one end of the magnetic pump body 1. Multiple positioning grooves 4 are opened in a ring shape inside the outer edge of the first fixed plate 3. The left end of the magnetic pump body 1 is provided with the pump head mechanism 5. The right end of the pump head mechanism 5 is fixed with a second fixed plate 6. Multiple sets of positioning locking components 8 are installed in a ring shape on the outer right side of the second fixed plate 6. The multiple sets of positioning locking components 8 are arranged in a one-to-one correspondence with the multiple positioning grooves 4. A sealing gasket 7 is embedded in the outer edge of the first fixed plate 3 near the second fixed plate 6.

[0027] Based on the above structure, the diameter and length of the first fixing plate 3 and the second fixing plate 6 are equal, and the two are connected by multiple sets of positioning and locking components 8 to form a disassembly structure.

[0028] In this embodiment, the arrangement of multiple sets of positioning and locking components 8 facilitates the connection between the first fixing plate 3 and the second fixing plate 6, and facilitates the installation of the pump head mechanism 5.

[0029] Based on the above structure, the positioning groove 4 includes an arc-shaped segment 41, a first circular hole 42, and a second circular hole 43. The first circular hole 42 and the second circular hole 43 are located at the two ends of the arc-shaped segment 41, and the arc-shaped segment 41, the first circular hole 42, and the second circular hole 43 are interconnected.

[0030] Based on the above structure, the center of the arc segment 41 coincides with the center of the first fixing plate 3. The diameters of the first circular hole 42 and the second circular hole 43 are equal and greater than the width of the arc segment 41. The thicknesses of the arc segment 41 and the first circular hole 42 are equal to the thickness of the first fixing plate 3, and the thickness of the second circular hole 43 is only half the thickness of the first fixing plate 3.

[0031] In this embodiment, the positioning grooves 4, which correspond one-to-one with the multiple sets of positioning and locking components 8, facilitate the insertion and positioning of the positioning and locking components 8 and the first fixing plate 3, thereby facilitating the quick installation and disassembly of the pump head mechanism 5.

[0032] Based on the above structure, the sealing gasket 7 is located between the first fixing plate 3 and the second fixing plate 6, and the sealing gasket 7 is made of rubber.

[0033] In this embodiment, the sealing gasket 7 facilitates the sealing of the connection between the first fixing plate 3 and the second fixing plate 6, preventing fluid leakage.

[0034] Based on the above structure, the positioning and locking assembly 8 includes a fixing screw 81, an anti-detachment disc 82, a movable sleeve 83, and an anti-slip ring 84. The fixing screw 81 is fixedly installed on the outer wall of the second fixing plate 6 near the first fixing plate 3. The anti-detachment disc 82 is fixedly connected to the end of the fixing screw 81 away from the second fixing plate 6. The movable sleeve 83 is threaded on the outer side of the threaded section of the fixing screw 81. The anti-slip ring 84 is adhesively fitted on the outer side of the movable sleeve 83 near the anti-detachment disc 82. The anti-slip ring 84 is made of rubber.

[0035] Based on the above structure, the diameter of the fixed screw 81 is equal to the width of the arc segment 41, and the diameter of the movable sleeve 83 is equal to the diameter of the first circular hole 42.

[0036] In this embodiment, the movable sleeve 83 is inserted into the first fixed plate 3 through the second circular hole 43, which can complete the positioning and installation of the pump head mechanism 5. As the movable sleeve 83 rotates, it can continuously pull the first fixed plate 3 and the second fixed plate 6 closer to each other, which can strongly compress the sealing gasket 7 between the two, effectively enhancing the sealing performance at the connection between the two.

[0037] The working principle of this utility model is as follows:

[0038] In use, first manually rotate the movable sleeve 83 to move it along the fixed screw 81 and make it fit with the anti-detachment disc 82. Then, align the three sets of positioning and locking components 8 with the first round hole 42 of the three positioning slots 4 and insert them. After the movable sleeve 83 passes through the first round hole 42, rotate the pump head mechanism 5 clockwise so that the fixed screw 81 enters the arc section 41 and the movable sleeve 83 moves to the second round hole 43. Then manually rotate the movable sleeve 83 in the opposite direction so that it moves away from the anti-detachment disc 82. One end of the movable sleeve 83 can be inserted into the second round hole 43. The movable sleeve 83 is engaged with the first fixed plate 3 through the second round hole 43, which completes the positioning and installation of the pump head mechanism 5.

[0039] Moreover, when one end of the movable sleeve 83 is inserted into the second round hole 43, the movable sleeve 83 can continue to rotate, which can continuously pull the first fixed plate 3 and the second fixed plate 6 closer to each other, thereby strongly squeezing the sealing gasket 7 between them, which can effectively enhance the sealing performance at the connection between the first fixed plate 3 and the second fixed plate 6 and prevent fluid leakage.

[0040] Compared with the reference document, this device is not only quicker and easier to assemble and disassemble, but also easier to operate. It can effectively enhance the connection strength and sealing between the pump head and the pump body, and can better meet market demands, making it more practical.

[0041] It should be noted that a rubber anti-slip ring 84 is also attached to the outer side of one end of the movable sleeve 83, which increases the friction between the hand and the movable sleeve 83 and facilitates rotation and adjustment. In addition, the fixing screw 81 is a trapezoidal screw with a self-locking function. These are all common existing products, so they will not be described in detail.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
