[0030] The directional words that appear in the following description are all directions shown in the figures, and do not limit the specific structure of the fixing bracket of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0031] The following embodiments of the present application only illustrate the fixing bracket using a cartridge filter as an example, but the application of the fixing bracket of the embodiments of the present application is not limited to the following embodiments, and can also be installed on filters in other fields to protect them.

[0032] In order to better understand the present application, the fixing bracket of the embodiment of the present application is described in detail below with reference to Figures 1 to 4.

[0033] Please refer to Figures 1 and 2. According to an embodiment of the present application, a fixing bracket 100 is proposed for fixing a filter 200. The fixing bracket 100 includes a first fixing member 10, a second fixing member 20 and a connecting member 30. The first fixing member 10 includes a first accommodating portion 11, and the first accommodating portion 11 matches the structure of the first end of the filter 200, and the first end can be inserted into the first accommodating portion 11; the second fixing member 20 includes a second accommodating portion 21, and the filter 200 includes a second end arranged opposite to the first end in its own length direction, and the second accommodating portion 21 matches the structure of the second end, and at least a portion of the second end can be arranged in the second accommodating portion 21; the connecting member 30 is connected between the first fixing member 10 and the second fixing member 20, one end of the connecting member 30 is connected to the first fixing member 10 and the other end is connected to the second fixing member 20.

[0034] When the filter 200 needs regular maintenance and filter element replacement, in order to facilitate the work of the staff, the fixed bracket 100 provided in this embodiment can be used to form a stable support for the filter 200, which is conducive to reducing the difficulty of disassembly and assembly of the filter 200.

[0035] Optionally, the first fixing member 10 and the second fixing member 20 can adopt a block structure, specifically a plastic material. The first accommodating portion 11 can be formed on the first fixing member 10 by a plastic process, and the second accommodating portion 21 can also be formed on the second fixing member 20. The first accommodating portion 11 is for fixing the first end of the filter 200 and the second accommodating portion 21 is for fixing the second end. Therefore, the specific structure of the first accommodating portion 11 and the second accommodating portion 21 depends on the structural form of the two ends of the filter 200. Different forms of filters 200 correspond to first accommodating portions 11 and second accommodating portions 21 with different structures. The present application does not specifically limit the specific structural form of the accommodating portion, and it is sufficient to form an accommodating and fixing portion for the corresponding two ends of the filter 200.

[0036] Optionally, the connecting member 30 can adopt a connecting rod structure, and the first fixing member 10 and the second fixing member 20 at both ends are connected by the rod-shaped structure, so that the fixing bracket 100 forms a stable structural whole. After the filter 200 is stably installed on the fixing bracket 100, under the connecting action of the connecting member 30, the first fixing member 10 and the second fixing member 20 can remain relatively stationary, thereby achieving stable support for both ends of the filter 200.

[0037] Before disassembling and assembling the filter 200, the fixing bracket 100 can be placed vertically first, and the filter 200 can be installed on the fixing bracket 100 first, that is, the two ends of the filter 200 are respectively inserted into the first accommodating portion 11 and the second accommodating portion 21 to form a structural match. Placing the fixing bracket 100 vertically is conducive to completing the assembly of the filter 200.

[0038] After the filter 200 is stably installed on the fixing bracket 100, the fixing bracket 100 and the filter 200 are placed horizontally. At this time, the staff can use a wrench to twist the threads on the filter 200 shell to complete the disassembly of the filter 200. Since the two ends of the filter 200 form a stable support on the fixing bracket 100, it is convenient for the staff to disassemble and assemble the filter 200, thereby improving the overall disassembly and assembly efficiency.

[0039] The embodiment of the present application provides a fixing bracket 100, which uses a first fixing member 10 and a second fixing member 20 to fix the two ends of the filter 200 respectively, specifically using the first accommodating portion 11 of the first fixing member 10 to fix the first end of the filter 200, and using the second accommodating portion 21 of the second fixing member 20 to fix the second end of the filter 200, thereby ensuring the stability of the filter 200 on the two fixing members, and then connecting the connecting member 30 between the two fixing members to keep the two fixing members relatively stationary, so that the filter 200 is installed as a whole on the fixing bracket 100, and the fixing bracket 100 can form a stable support for the filter 200, which is convenient for the staff to complete the disassembly and assembly of the filter 200 shell, thereby reducing the difficulty of work, improving the efficiency of disassembly and assembly of the filter 200, and also improving the reliability of disassembly and assembly of the filter 200, and preventing the risk of leakage caused by insufficient threaded connection.

[0040] As an optional embodiment, please refer to Figure 2, the first accommodating portion 11 includes a first tube groove 12, the opening of the first tube groove 12 faces the second fixing member 20, the first tube groove 12 extends along the first direction, and the first end of the filter 200 includes a first tube segment extending along the first direction, and the first tube segment can be set in the first tube groove 12.

[0041] In this embodiment, the main consideration is that a first pipe section is provided at the first end of the filter 200. Optionally, the first pipe section extends along a first direction, and the first pipe section can accommodate the flow of liquid. Therefore, in the process of fixing the first end of the filter 200, it is necessary to provide a first pipe groove 12 extending along the first direction at a corresponding position of the first accommodating portion 11, so as to match the first pipe section of the filter 200 and accommodate the first pipe section.

[0042] Optionally, the first tube groove 12 can be a semicircular arc groove structure, and the opening of the tube groove faces the second fixing member 20. The present application does not specifically limit the specific shape and size of the first tube groove 12, which depends on the shape and size of the first tube segment in different filters 200, and ultimately ensures that the first tube segment can be accommodated.

[0043] The embodiment of the present application provides a fixing bracket 100, which can accommodate the first tube segment of the filter 200 by setting a first tube groove 12 in the first accommodating portion 11, and can adapt to the end fixation of the filter 200 with the first tube segment, facilitate the accommodation and fixation of the infusion tube, have a better fixing effect, and provide reliable protection for the subsequent disassembly and assembly of the filter 200.

[0044] As an optional embodiment, please refer to Figure 2, the first accommodating portion 11 includes a second tube groove 13, the second tube groove 13 extends along the second direction and intersects with the first tube groove 12, and the first end of the filter 200 includes a second tube segment extending along the second direction, and the second tube segment can be set in the second tube groove 13.

[0045] Considering that the filter 200 will be connected to multiple infusion pipes in the circulation system, the first end of the filter 200 will also have a second pipe section intersecting with the first pipe section. When the first end of the filter 200 is fixed using the first accommodating portion 11, a second pipe groove 13 can be correspondingly set in the first accommodating portion 11 to accommodate the second pipe section.

[0046] The second pipe section extends along the second direction and intersects with the first pipe section. Optionally, the two are vertically connected. In the process of inserting the first end of the filter 200 into the first accommodating portion 11, it is necessary to install the first pipe section corresponding to the first pipe groove 12, and the second pipe section corresponding to the second pipe groove 13, so that the first end of the filter 200 is stably inserted into the first accommodating portion 11.

[0047] An embodiment of the present application provides a fixing bracket 100, which achieves the accommodation and fixation of the second tube segment of the filter 200 by arranging a second tube groove 13 intersecting with the first tube groove 12 in the first accommodating portion 11, so that the second tube groove 13 extends along the second direction. The first accommodating portion 11 can adapt to the end structure of the filter 200 with multiple tube segments, thereby improving the adaptability of the fixing bracket 100 to the filter 200 and ensuring stable support for the end of the filter 200.

[0048] As an optional embodiment, please refer to Figure 1, the first accommodating portion 11 includes a square groove 14 located at the intersection of the first tube groove 12 and the second tube groove 13, and the opening of the square groove 14 faces the second fixing member 20. The first end of the filter 200 includes a square portion located at the intersection of the first tube segment and the second tube segment, and the square portion can be set in the square groove 14.

[0049] In this embodiment, the first end of the filter 200 has a square portion at the intersection of the first pipe section and the second pipe section. Considering that when the first end is inserted into the first accommodating portion 11, it is necessary to structurally match and accommodate the square portion at the first end, a square groove 14 is provided in the first accommodating portion 11 in this embodiment to match the square portion.

[0050] Optionally, the specific shape and size of the square groove 14 need to be determined according to the shape and size of the square portion of the filter 200 to ensure that the square portion can be smoothly accommodated in the square groove 14. When the first end of the filter 200 is inserted into the first accommodating portion 11, it is necessary to plug the various structures at the above-mentioned first end into the corresponding slots in the first accommodating portion 11 to achieve structural matching and fix the end of the filter 200.

[0051] An embodiment of the present application provides a fixing bracket 100, which realizes the fixation of the multi-structure end portions of the filter 200 by setting a square groove 14 in the first accommodating portion 11 to correspond to the square portion of the filter 200, thereby improving the adaptability of the fixing bracket 100 to filters 200 with different structures and having a better fixing effect.

[0052] As an optional embodiment, please refer to Figure 2, the fixing bracket 100 includes a locking member 40, and the first fixing member 10 is provided with a locking hole connected to the first accommodating portion 11. The locking member 40 can be inserted into the locking hole and abut against the filter 200 in the first accommodating portion 11 to fix the filter 200 on the first fixing member 10.

[0053] After the first end of the filter 200 is inserted into the first accommodating portion 11 , considering the stability of the filter 200 , the first end of the filter 200 needs to be further reinforced and connected to the first fixing member 10 . Therefore, in this embodiment, the filter 200 is locked by utilizing a locking member 40 .

[0054] Specifically, a locking hole is provided on the first fixing member 10, and the locking hole needs to be connected to the first accommodating portion 11, so that when the locking member 40 is inserted into the locking hole, the locking member 40 can pass through the locking hole and abut against the filter 200 in the first accommodating portion 11, thereby further reinforcing the filter 200.

[0055] Optionally, the locking piece 40 can be a hand screw, and the corresponding locking hole can be a threaded hole. After completing the insertion of the filter 200, the staff screws the locking piece 40 into the locking hole until it abuts against the internal filter 200, thereby fixing the end of the filter 200.

[0056] The present application does not impose any special restrictions on the size and distribution position of the locking holes on the first fixing member 10. Multiple locking holes can be set at different positions of the first fixing member 10, so that the locking members 40 can be inserted at different positions to lock the filter 200 at multiple angles, thereby achieving a better fixing effect.

[0057] The embodiment of the present application provides a fixing bracket 100, which further fixes the filter 200 by setting a locking hole on the first fixing member 10 and inserting the locking member 40 into the locking hole, thereby further ensuring the stability of the filter 200 installed on the fixing bracket 100, providing reliable protection for subsequent disassembly and assembly operations of the staff, and ensuring the stability of the disassembly and assembly process of the filter 200.

[0058] As an optional embodiment, the locking hole includes a first through hole 1, which extends in the first direction. The locking piece 40 can be inserted into the first through hole 1 and abut against the filter 200 in the first direction to fix the filter 200 in the first direction.

[0060] Optionally, first through holes 1 can be respectively provided on two opposite side surfaces of the first fixing member 10 along the first direction, and the two through holes each penetrate the first fixing member 10 and communicate with the first accommodating portion 11 inside. After the filter 200 is completed, the locking members 40 are respectively inserted into the corresponding first through holes 1, and the locking members 40 on the two side surfaces are screwed in toward each other and abut against the filter 200 together, thereby realizing bidirectional locking of the filter 200 and further preventing the filter 200 from moving unbalanced in the first direction.

[0061] An embodiment of the present application provides a fixing bracket 100, which locks the filter 200 in the first direction by providing a first through hole 1 extending along the first direction on the first fixing member 10, and inserting a locking member 40 into the first through hole 1, thereby further improving the stability of the filter 200 in the first direction and facilitating subsequent disassembly and assembly of the filter 200.
