Detailed Implementation

[0036] The present invention will be further described in detail below with reference to embodiments:

[0037] Example 1

[0038] like Figure 1 and Figure 2 As shown, this utility model provides a vacuum filtration device that is easy to assemble and disassemble quickly, comprising:

[0039] The system comprises a collection bottle 1, a filter base 2, a filter cup 3, a vacuum pump, and a filter medium. The filter base 2 is placed above the collection bottle 1, the filter cup 3 is located above the filter base 2, and the vacuum pump is located to one side of the collection bottle 1. The system is characterized by: a first clamping plate 5 fixedly connected to the outer side of the filter cup 3; a second clamping plate 6 fixedly connected to the outer side of the filter base 2; a sealing assembly between the first clamping plate 5 and the second clamping plate 6 for sealing the filter cup 3 and the filter base 2; and several first clamping blocks 7 evenly and fixedly connected along the circumferential direction on the second clamping plate 6. Block 7 is hollow. A first through groove 8 is provided on the first clamping block 7. A fixing groove 9, a first reaction groove 33, a second reaction groove 34 and a third reaction groove 35 are evenly arranged along the circumference on the first clamping plate 5. The first reaction groove 33, the second reaction groove 34 and the third reaction groove 35 are interconnected. A buckling component and a control component are respectively connected inside the first clamping plate 5. The buckling component is used to cooperate with the first clamping block 7 to connect the filter cup 3 and the filter base 2. The control component is used to quickly control the buckling component so that the filter cup 3 and the filter base 2 can be quickly fixed and detached.

[0040] In this embodiment, the vacuum filtration device consists of a collection bottle 1, a filter base 2, a filter cup 3, a vacuum pump, and a filter medium. Since the vacuum filtration device is a mature technology in the prior art (where the filter base 2 and the collection bottle 1 are connected by threads), it will not be described in detail here. When the vacuum filtration device needs to be disassembled, the working state of the locking component can be quickly controlled by the control component, so that the locking component is in the closed state. At this time, the first locking block 7 disengages from the fixing groove 9 on the first clamping plate 5, and the first clamping plate 5 and the second clamping plate 6 separate. Then, the filter cup 3, which is fixedly connected to the first clamping plate 5, and the filter base 2, which is fixedly connected to the second clamping plate 6, can be disengaged. Through the cooperation between the control component and the locking component, the filter cup 3 and the filter base 2 can be quickly disengaged. Simultaneously, a sealing component ensures the internal sealing. By having the first locking block 7 cooperate with the fixing groove 9 to slide, the first clamping plate 5 and the second clamping plate 6 can be quickly positioned, thereby enabling rapid disassembly and assembly of the vacuum filtration device and improving its working efficiency.

[0041] like Figure 3 As shown, in this embodiment, preferably, the sealing assembly includes a first rubber ring 10 and a second rubber ring 11. The first rubber ring 10 is fixedly connected to the filter cup 3, and the second rubber ring 11 is fixedly connected to the filter base 2. The cross-section of the first rubber ring 10 is triangular, and the first rubber ring 10 and the second rubber ring 11 are used together.

[0042] When the filter cup 3 is placed above the filter base 2 when assembly is required, the first rubber ring 10 on the filter cup 3 will be pressed against the second rubber ring 11 on the filter base 2, so that the filter cup 3 and the filter base 2 will not leak when connected.

[0043] As shown in Figure 5 and Figure 7 Preferably, the buckle part comprises a shell 12 located inside the first reaction tank 33 and fixedly connected with the first clamping plate 5, a moving block 13 slidably connected in the shell 12, a chuck 14 fixedly connected to one side of the moving block 13, a pressure spring 15 fixedly connected to the side of the moving block 13 away from the chuck 14, the other end of the pressure spring 15 fixedly connected with the shell 12, a limiting block 16 fixedly connected above the moving block 13, the limiting block 16 slidably connected with the shell 12, the limiting block 16 slidably connected with the first clamping plate 5 through the third reaction tank 35, a second clamping block 17 arranged in the fixed groove 9, the second clamping block 17 used in cooperation with the first clamping block 7, a second through groove 18 opened on the second clamping block 17, the chuck 14 used in cooperation with the first clamping block 7 and the second clamping block 17 through the first through groove 8 and the second through groove 18.

[0044] When the vacuum filtration device needs to be assembled, first adjust the angle of the filter base 2 and the filter cup 3 so that the first clamping block 7 is located below the fixed groove 9, then attach the first clamping plate 5 and the second clamping plate 6, at this time the first clamping block 7 will enter the fixed groove 9 and slide with the second clamping block 17, and the first through groove 8 and the second through groove 18 will coincide, then adjust the movement of the limiting block 16 through the control part, drive the moving block 13 to move through the limiting block 16, the moving block 13 moving will drive the chuck 14 to enter the first through groove 8 and the second through groove 18, so that the first clamping block 7 and the second clamping block 17 are clamped by the chuck 14, thereby fixing the first clamping plate 5 and the second clamping plate 6, at this time the filter base 2 and the filter cup 3 are in a fixed state; when disassembling, adjust the limiting block 16 so that the pressure spring 15 is in a compressed state, at this time the chuck 14 is separated from the first clamping block 7 and the second clamping block 17, thereby separating the first clamping plate 5 and the second clamping plate 6.

[0045] As shown in Figure 4 and Figure 8As shown, preferably, the control component comprises a fixing block 19, a first stop block 20 and a second stop block 21, the fixing block 19, the first stop block 20 and the second stop block 21 are located in the second reaction tank 34, the fixing block 19 is in sliding connection with the first clamping plate 5, a recess is formed in the fixing block 19, a protrusion 22 is in sliding connection in the recess, an inclined surface 23 is arranged on the protrusion 22, a resilient spring 24 is fixedly connected to one side of the protrusion 22 away from the inclined surface 23, the other end of the resilient spring 24 is fixedly connected to the fixing block 19, one end of the fixing block 19 is fixedly connected with a connecting rod 25, the other end of the connecting rod 25 away from the fixing block 19 is fixedly connected with a button, the end of the fixing block 19 away from the connecting rod 25 is fixedly connected with a return spring 26, the other end of the return spring 26 is fixedly connected to the first clamping plate 5, one side of the fixing block 19 is fixedly connected with a pressing block 27, the pressing block 27 is located in the third reaction tank 35 and is in sliding connection with the first clamping plate 5, and the pressing block 27 is in abutment with the limiting block 16.

[0046] The first stop block 20 is fixedly connected to the first clamping plate 5, the second stop block 21 is in sliding connection with the first clamping plate 5, one side of the second stop block 21 is fixedly connected with a sliding block 28, one side of the sliding block 28 is fixedly connected with a telescopic spring 29, the other end of the telescopic spring 29 is fixedly connected to the first clamping block, and the first stop block 20 and the second stop block 21 are both arranged in a triangular shape.

[0047] When the vacuum filter device needs to be disassembled, the button is pressed, which drives the connecting rod 25 to move, and the connecting rod 25 transmits power to the fixed block 19 to push the fixed block 19 to move. At this time, the fixed block 19 moves to extrude the return spring 26. The inclined surface 23 provided on the protrusion 22 slidingly located in the fixed block 19 contacts the first stop block 20, and the first stop block 20 extrudes the inclined surface 23 of the protrusion 22, so that the protrusion 22 slides to the inside of the fixed block 19. At this time, the elastic spring 24 is in a compressed state, and the return spring 26 is also in a compressed state. After passing through the first stop block 20, the protrusion 22 resets under the action of the elastic spring 24. At this time, the protrusion 22 is clamped with the first stop block 20 under the action of the return spring 26 and the elastic spring 24. Thus, the pressure spring 15 is in a compressed state, and the clamping head 14 is separated from the first clamping block 7 and the second clamping block 17. When the vacuum filter device needs to be assembled and disassembled, the first clamping block 7 is slid into the fixed slot 9 to make the first through slot 8 and the second through slot 18 coincide, and then the button is continuously pressed to drive the connecting rod 25 to make the protrusion 22 move to the second stop block 21. At this time, the protrusion 22 is extruded when passing through the second stop block 21, so that the elastic spring 24 is in a compressed state, and the return spring 26 is still in a compressed state. At this time, the protrusion 22 is retracted into the fixed block 19 and passes through the second stop block 21. When the protrusion 22 passes through the second stop block 21 and resets, the button is then released. At this time, the return spring 26 drives the fixed block 19 to move, and the protrusion 22 drives the second stop block 21 to move. At this time, the telescopic spring 29 is in a compressed state. When the second stop block 21 contacts the first stop block 20, the protrusion 22 is extruded by the pressure and the elastic spring 24 is compressed by the protrusion 22. The protrusion 22 retracts into the fixed block 19 along the inclined surface 23 of the second stop block 21 and passes through the second stop block 21 and the first stop block 20. When the protrusion 22 passes through the first stop block 20 and the second stop block 21, the protrusion 22 resets. The second stop block 21 also resets under the action of the telescopic spring 29. At this time, the limiting block 16 in contact with the pressure block 27 first extrudes the pressure spring 15, and then resets under the action of the pressure spring 15, so that the clamping head 14 enters the first clamping block 7 and the second clamping block 17 through the first through slot 8 and the second through slot 18, thereby clamping the first clamping plate 5 and the second clamping plate 6, achieving the purpose of quick assembly and disassembly, and improving the working efficiency of the vacuum filter device.

[0048] As Figure 2 shown, preferably, the first clamping block 7 is slidingly connected with a guide block 30. One side of the guide block 30 is fixedly connected with a tension spring 31, and the other end of the tension spring 24 is fixedly connected with the first clamping block 7.

[0049] By setting the tension spring 31 and the guide block 30 in the interior of the first clamping block 7, automatic disengagement can be realized when the first clamping plate 5 and the second clamping plate 6 are separated, because when the first clamping block 7 slides with the second clamping block 17, the second clamping block 17 will press the guide block 30 and thus press the tension spring 31, and when disengagement is needed, the first clamping block 7 and the second clamping block 17 are no longer clamped, and the tension spring 31 will reset, thus providing the first clamping plate 5 with a spring force through the second clamping block 17, so that the first clamping plate 5 and the second clamping plate 6 can be separated more quickly.

[0050] As shown in Figure 8 , preferably, the connecting rod 25 is provided with a scale line.

[0051] By setting the scale line on the connecting rod 25, the working state of the clamping component can be quickly adjusted according to the scale, thereby improving the working efficiency of the vacuum filtration device.

[0052] As shown in Figure 8 , preferably, the connecting rod 25 is provided with a plurality of lightening grooves 32.

[0053] By setting the lightening grooves 32, the weight of the connecting rod 25 can be effectively reduced, so that the connecting rod 25 is lightweight, and thus the worker can quickly press the button to adjust the clamping component, thereby improving the working efficiency of the vacuum filtration device.

[0054] The working principle of the vacuum filtration device convenient for quick disassembly will be described below.

[0055] As shown in Figure 1 - Figure 8When the vacuum filtration device needs to be disassembled, the working state of the buckle member can be quickly controlled by the control member, so that the buckle member is in a closed state, at this time the first clamping block 7 is separated from the fixed groove 9 opened on the first clamping plate 5, the first clamping plate 5 and the second clamping plate 6 are separated, then the filter cup 3 fixedly connected with the first clamping plate 5 and the filter base 2 fixedly connected with the second clamping plate 6 can be separated, the filter cup 3 and the filter base 2 can be quickly separated through the cooperation between the control member and the buckle member, and the sealing member can ensure the sealing of the inside. The first clamping plate 5 and the second clamping plate 6 can be quickly positioned by the cooperation between the first clamping block 7 and the fixed groove 9, so that the vacuum filtration device can be quickly disassembled. When assembling, place the filter cup 3 above the filter base 2, at this time the first rubber ring 10 on the filter cup 3 cooperates with the second rubber ring 11 on the filter base 2, the first rubber ring 10 is extruded with the second rubber ring 11, so that the filter cup 3 and the filter base 2 will not leak when connected. When the vacuum filtration device needs to be assembled, first adjust the angle of the filter base 2 and the filter cup 3, so that the first clamping block 7 is located below the fixed groove 9, then the first clamping plate 5 and the second clamping plate 6 are attached, at this time the first clamping block 7 will enter the fixed groove 9 and slide with the second clamping block 17, and the first through slot 8 and the second through slot 18 are coincided, then the control member adjusts the movement of the limiting block 16, the movement block 13 is driven to move by the limiting block 16, the movement of the movement block 13 drives the clamp head 14 to enter the first through slot 8 and the second through slot 18, so that the first clamping block 7 and the second clamping block 17 are clamped by the clamp head 14, so that the first clamping plate 5 and the second clamping plate 6 are fixed, at this time the filter base 2 and the filter cup 3 are in a fixed state; when disassembling, adjust the limiting block 16 so that the pressure spring 15 is in a compressed state, at this time the clamp head 14 is separated from the first clamping block 7 and the second clamping block 17, so as to separate the first clamping plate 5 and the second clamping plate 6.When the vacuum filter device needs to be disassembled, the button is pressed, which drives the connecting rod 25 to move, and the connecting rod 25 transmits power to the fixed block 19 to push the fixed block 19 to move. At this time, the fixed block 19 moves to extrude the return spring 26. The inclined surface 23 provided on the protrusion 22 sliding in the fixed block 19 contacts the first stop block 20, and the first stop block 20 extrudes the inclined surface 23 of the protrusion 22, so that the protrusion 22 slides to the inside of the fixed block 19. At this time, the elastic spring 24 is in a compressed state, and the return spring 26 is also in a compressed state. After passing the first stop block 20, the protrusion 22 resets under the action of the elastic spring 24. At this time, the protrusion 22 is clamped with the first stop block 20 under the action of the return spring 26 and the elastic spring 24, so that the limiting block 16 is driven to move by the pressing block 27. At this time, the pressure spring 15 is in a compressed state, and the clamping head 14 is separated from the first clamping block 7 and the second clamping block 17. When the vacuum filter device needs to be assembled and disassembled, the first clamping block 7 is slid into the fixed slot 9 to make the first through slot 8 and the second through slot 18 coincide, and then the button is continuously pressed to drive the connecting rod 25 to make the protrusion 22 move to the second stop block 21. At this time, the protrusion 22 is extruded when passing the second stop block 21, so that the elastic spring 24 is in a compressed state, and the return spring 26 is still in a compressed state. At this time, the protrusion 22 is retracted into the fixed block 19 and passes the second stop block 21. When the protrusion 22 passes the second stop block 21 and resets, the button is then released. At this time, the return spring 26 drives the fixed block 19 to move, and the protrusion 22 drives the second stop block 21 to move. At this time, the telescopic spring 29 is in a compressed state. When the second stop block 21 contacts the first stop block 20, the protrusion 22 is extruded by the pressure and extrudes the elastic spring 24. The elastic spring 24 is compressed by the protrusion 22, and the protrusion 22 retracts into the fixed block 19 along the inclined surface 23 of the second stop block 21 and passes the second stop block 21 and the first stop block 20. When the protrusion 22 passes the first stop block 20 and the second stop block 21, the protrusion 22 resets. The second stop block 21 also resets under the action of the telescopic spring 29. At this time, the limiting block 16 in contact with the pressing block 27 first extrudes the pressure spring 15, and then resets under the action of the pressure spring 15, so that the clamping head 14 enters the first clamping block 7 and the second clamping block 17 through the first through slot 8 and the second through slot 18, thereby clamping the first clamping plate 5 and the second clamping plate 6. By providing the first clamping block 7 with a tension spring 31 and a guide block 30, the first clamping plate 5 and the second clamping plate 6 can be automatically separated when they are separated. Because when the first clamping block 7 and the second clamping block 17 slide, the second clamping block 17 extrudes the guide block 30 to extrude the tension spring 31. When it needs to be separated, the first clamping block 7 and the second clamping block 17 are no longer clamped. At this time, the tension spring 31 resets, thereby providing the first clamping plate 5 with a elastic force through the second clamping block 17, so that the first clamping plate 5 and the second clamping plate 6 can be separated more quickly.The scale line arranged on the connecting rod 25 can quickly adjust the working state of the buckle part according to the scale, thereby improving the working efficiency of the vacuum filtration device. The weight reduction groove 32 can effectively reduce the weight of the connecting rod 25, so that the connecting rod 25 is lightened, thereby enabling the worker to quickly press the button to adjust the buckle part, thereby improving the working efficiency of the vacuum filtration device.

[0056] The above is a detailed description of the general utility model, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, without departing from the spirit of the utility model, the modifications or improvements are within the scope of the utility model.
