Description

Technical Field

[0001] This utility model relates to the field of filter installation technology, specifically a filter base installation structure. Background Art

[0002] Filters are an indispensable device in pipelines transporting media. They are usually installed at the inlet end of pressure reducing valves, pressure relief valves, level control valves, and other equipment. A filter consists of a cylinder, a stainless steel filter screen, a sewage discharge section, a transmission device, and an electrical control section. After the water to be treated passes through the filter screen cylinder, impurities are blocked. When cleaning is required, simply remove the detachable filter screen cylinder, clean it, and reinstall it. Therefore, it is extremely convenient to use and maintain.

[0003] Currently, existing filters are usually installed on the same base as other devices, which facilitates the connection of filters to other devices;

[0004] Filters inevitably encounter various problems after a period of use, requiring disassembly and repair. However, existing filters are generally fixed to the base with bolts, which is inconvenient for maintenance personnel and affects maintenance efficiency. Utility Model Content

[0005] In view of the technical problems in the prior art, the present invention provides a filter base mounting structure to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A filter base mounting structure includes a base plate. A support block is provided at the center of the upper side of the base plate corresponding to the bottom of the filter. An annular block is provided around the support block. The inner diameter of the annular block is adapted to the outer periphery of the bottom of the filter. The lower side of the annular block is inserted into the upper side of the base plate. An annular groove is provided on the upper side of the base plate corresponding to the annular block for the annular block to slide up and down. Limiting structures are provided on the left and right sides of the base plate corresponding to the sliding parts of the annular block. Multiple snap-fit ​​structures are arranged in an annular array on the upper side of the annular block corresponding to the bottom of the filter. When the annular block moves downward to the bottom of the annular groove, it can be limited by the limiting structures, and the snap-fit ​​structures can be snapped into the outer periphery of the bottom of the filter.

[0008] Preferably, the limiting structure includes a horizontally arranged limiting rod, one end of which passes through the bottom plate and extends into the annular groove. The limiting rod is slidably connected to the bottom plate. An annular limiting block is provided on the lower periphery of the end of the annular block located in the annular groove. When the annular block slides down to the bottom of the annular groove, the limiting rod can abut against the upper side of the annular limiting block.

[0009] Preferably, the base plate has a movable cavity corresponding to the limiting rod. The end of the limiting rod located in the movable cavity facing the annular block is provided with a limiting slider that is slidably connected to the movable cavity. A first spring is provided in the movable cavity on the side of the limiting slider facing away from the annular block. The first spring is inserted into the limiting rod. A handle is provided at the end of the limiting rod located outside the base plate.

[0010] Preferably, the end of the limiting rod located in the annular groove has an inclined surface that slopes inward from top to bottom.

[0011] Preferably, the bottom of the annular groove corresponds to the annular block, and the annular array is provided with multiple second springs.

[0012] Preferably, the snap-fit ​​structure includes an inverted L-shaped snap-fit ​​block, and a clearance groove is provided on the upper outer periphery of the annular block corresponding to the snap-fit ​​block. The lower end of the snap-fit ​​block is hinged to the inner wall of the clearance groove.

[0013] Preferably, a torsion spring is provided at the hinge point between the snap-fit ​​block and the relief groove, and a steel wire is fixedly connected between the edge of the upper side plate of the base plate and the outer wall of the snap-fit ​​block. When the annular block moves downward to the bottom of the annular groove, the steel wire is in a relaxed state. When the annular block moves upward, the steel wire will gradually become taut and pull the snap-fit ​​block.

[0014] Preferably, an anti-slip pad is provided on the upper side of the snap-fit ​​block at the outer periphery of the bottom of the filter.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model provides a filter base mounting structure. When installing the filter, first align the bottom of the filter with the support block inside the annular block, then press down on the upper side of the annular block. At this time, the annular limiting block located in the annular groove moves downward until it abuts against the inclined surface of the limiting rod. During the continuous downward movement, by abutting against the inclined surface, the limiting rod can be pushed outward until the annular limiting block reaches the bottom of the annular groove. At this point, under the action of the first spring, the limiting rod is pushed, thus placing the limiting rod on the upper side of the annular limiting block, thereby limiting its position. Simultaneously, as the annular block descends, the steel wire gradually loses its pull on the locking block. At this time, the locking block is rotated inward to a vertical position by the action of the torsion spring until the annular block descends to the bottom of the annular groove. At this point, the locking block abuts against the outer periphery of the bottom of the filter, fixing it in place. The installation process only requires pressing the annular block downward, making installation convenient and quick.

[0017] During maintenance and disassembly, simply pull the limit rods on both sides of the base plate outwards. Under the action of the second spring, the annular block will be pushed out. As the annular block moves upward, the steel wire continuously pulls the locking block, thereby pulling it out of the bottom of the filter, releasing the limit, and disassembling in one step. This is highly efficient and greatly reduces the burden on the staff. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See also Figure 1-4The embodiments proposed in this application include: a filter base mounting structure, including a base plate 1, a support block 3 corresponding to the bottom of the filter 2 at the middle of the upper side of the base plate 1, an annular block 4 corresponding to the periphery of the support block 3, the inner diameter of the annular block 4 being adapted to the bottom periphery of the filter 2, the lower side of the annular block 4 being inserted into the upper side of the base plate 1, an annular groove 11 for the annular block 4 to slide up and down being opened on the upper side of the base plate 1 corresponding to the annular block 4, a plurality of second springs 12 being arranged in an annular array at the bottom of the annular groove 11 corresponding to the annular block 4, a limiting structure 5 being provided on the left and right sides of the base plate 1 corresponding to the sliding part of the annular block 4, and a plurality of snap-fit ​​structures 6 being arranged in an annular array on the upper side of the annular block 4 corresponding to the bottom of the filter 2, when the annular block 4 moves downward to the bottom of the annular groove 11, it can be limited by the limiting structure 5, and the snap-fit ​​structure 6 can be snapped into the bottom periphery of the filter 2;

[0025] The filter 2 placed on the support block 3 is fixed by the limiting structure 5 and the snap-fit ​​structure 6 when the annular block 4 moves down, making installation convenient and quick. With the setting of the limiting structure 5 and the second spring 12, the filter 2 can be disassembled in one step, which is highly efficient and greatly reduces the burden on the staff.

[0026] In another embodiment, please refer to Figure 1-4 The limiting structure 5 includes a limiting rod 51 arranged laterally. One end of the limiting rod 51 facing the side wall of the bottom plate 1 passes through the bottom plate 1 and extends into the annular groove 11. The limiting rod 51 is slidably connected to the bottom plate 1. An annular block 41 is provided on the lower periphery of one end of the annular block 4 located in the annular groove 11. When the annular block 4 slides down to the bottom of the annular groove 11, the limiting rod 51 can abut against the upper side of the annular limiting block 41.

[0027] In this embodiment, a movable cavity 52 is provided inside the base plate 1 corresponding to the limiting rod 51. The part of the limiting rod 51 located inside the movable cavity 52 facing the annular block 4 is provided with a limiting slider 53 that is slidably connected to the movable cavity 52. ​​A first spring 54 is provided inside the movable cavity 52 on the side of the limiting slider 53 facing away from the annular block 4. The first spring 54 is inserted into the limiting rod 51. A handle 55 is provided at the end of the limiting rod 51 located outside the base plate 1. A slope 56 that slopes inward from top to bottom is provided at the end of the limiting rod 51 located in the annular groove 11.

[0028] When installing the filter 2, first align the bottom of the filter 2 with the support block 3 inside the annular block 4, and then press down on the upper side of the annular block 4. At this time, the annular limiting block 41 located in the annular groove 11 moves downward to abut against the inclined surface 56 of the limiting rod 51. During the continuous downward movement, the limiting rod 51 can be pushed outward by abutting against the inclined surface 56 until the annular limiting block 41 reaches the bottom of the annular groove 11. At this time, the limiting rod 51 is pushed under the action of the first spring 54, so that the limiting rod 51 is located on the upper side of the annular limiting block 41, thereby limiting it. Conversely, when disassembling, by pulling out the limiting rods 51 on both sides of the base plate 1, the annular block 4 is pushed out under the action of the second spring 12, releasing the limitation on the annular limiting block 41, which is convenient and quick.

[0029] In another embodiment, please refer to Figure 1-4 The snap-fit ​​structure 6 includes an inverted L-shaped snap-fit ​​block 61. A relief groove 62 is provided on the outer side of the upper side of the annular block 4 corresponding to the snap-fit ​​block. The lower end of the snap-fit ​​block 61 is hinged to the inner wall of the relief groove 62. A torsion spring 63 is provided at the hinge between the snap-fit ​​block 61 and the relief groove 62. An anti-slip pad 65 is provided on the upper side of the snap-fit ​​block 61 corresponding to the outer side of the bottom of the filter 2. A steel wire 64 is fixedly connected between the edge of the upper side plate of the base plate 1 and the outer wall of the snap-fit ​​block 61. When the annular block 4 moves downward to the bottom of the annular groove 11, the steel wire 64 is in a relaxed state. When the annular block 4 moves upward, the steel wire 64 will gradually become taut and pull the snap-fit ​​block 61.

[0030] During installation, as the ring block 4 is pressed down, the snap-fit ​​block 61 descends simultaneously with the ring block 4. At this time, the steel wire 64 will gradually lose its pull on the snap-fit ​​block 61. Then, the snap-fit ​​block 61 is rotated inward to vertical by the action of the torsion spring 63 until the ring block 4 descends to the bottom of the annular groove 11. At this time, the snap-fit ​​block 61 is just abutting against the bottom outer periphery of the filter 2 to fix it. At the same time, the anti-slip pad 65 is used to increase the friction during snap-fit.

[0031] During maintenance and disassembly, the annular block 4 moves upward after being released from the limit structure 5. As the annular block 4 moves upward, the steel wire 64 continuously pulls the snap-fit ​​block 61 and rotates it outward along the hinge, thereby pulling it out of the bottom of the filter 2, releasing the limit, and disassembling in one step. This is highly efficient and greatly reduces the burden on the staff.
