[0003] Currently, in existing technologies, when installing filter elements, qualified filter elements are fitted onto fixing screws, and each filter element is then installed in sequence with the filter element cap, gasket, and nut. Because there are gaps between filter elements, if any part, such as a gasket or nut, falls into the filter separator during installation, the entire filter element needs to be removed, cleaned, and reinstalled. Therefore, a safety plate for installing filter elements in a filter separator is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a safety plate for installing filter elements in a filter separator, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a safety plate for installing filter elements in a filter separator, comprising a filter separator body, a screw fixedly connected to the bottom of the filter separator body, a filter element body sleeved on the outer wall of the screw, a safety plate body movably fitted to the top of the filter element body, and a movable component at the bottom of the safety plate body for easy insertion into the filter separator, the movable component comprising:

[0006] A circular groove is formed at the bottom of the safety plate body. A straight groove is formed on the outer wall of the circular groove, and the straight groove is evenly distributed along the circumference of the circular groove.

[0007] A disc is rotatably connected to the inner wall of a circular groove. The diameter of the circular groove is slightly larger than the diameter of the disc, and a gap is reserved between them to ensure that the disc can rotate flexibly in the circular groove. A curved groove is formed on the outer wall of the disc.

[0008] A connecting rod is slidably connected to the inner wall of a straight groove. One end of the connecting rod is fixedly connected to a locking block, and the end of the connecting rod away from the locking block is fixedly connected to an arc-shaped plate.

[0009] Preferably, the card block is slidably connected to the inner wall of the curved groove, the width of the curved groove matches the width of the card block, and a gap is reserved between the two to ensure that the card block slides in the curved groove.

[0010] Preferably, the bottom of the safety plate body is provided with a straight groove II, and a moving block is slidably connected to the inner wall of the straight groove II. The bottom of the moving block is fixedly connected to the arc plate, and the straight groove II and the moving block assist the movement of the arc plate.

[0011] Preferably, a column is fixedly connected to the top of the disc, the column extends movably through the safety plate body and upwards, and a limit block is fixedly connected to the outer wall of the extended end of the column to prevent the column from coming out of the safety plate body.

[0015] This utility model provides a safety plate for installing filter elements in a filter separator. It has the following beneficial effects:

[0016] (1) Before installation, the safety plate used for installing the filter element of the filter separator can be rotated to make the arc plate retract to the bottom of the safety plate body. At this time, the overall diameter of the safety plate is smaller than the top diameter of the filter separator body, and it can be easily put into the filter separator along the screw. After placement, rotate the knob in the opposite direction, and the arc plate moves outward and fits tightly against the inner wall of the filter separator body to prevent any parts such as gaskets and nuts from falling into the filter separator during the installation process.

[0017] (2) When the filter element of the safety plate used for filter separator installation needs to be replaced, first remove the nut and washer. By turning the knob, the disc drives the locking block, connecting rod and arc plate to move. The arc plate retracts inward to the bottom of the safety plate body. The operation process does not require complicated tools. The safety plate can be quickly taken out by simply rotating the knob, which solves the problem that the safety plate diameter is too large and must be placed vertically. Attached Figure Description

[0029] 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.

[0030] Please see Figures 1-7This utility model proposes a safety plate for installing filter elements in a filter separator, including a filter separator body 1, a screw 2 fixedly connected to the bottom of the filter separator body 1, and multiple screws 2 arranged in a circular array around the center of the filter separator. A filter element body 3 is sleeved on the outer wall of the screw 2, and a safety plate body 4 is movably attached to the top of the filter element body 3. A movable component 5 is provided at the bottom of the safety plate body 4 to facilitate the insertion of the safety plate body 4 into the filter separator.

[0031] In an embodiment of this utility model, to facilitate the placement of the safety plate into the filter separator, the moving component 5 specifically includes a circular groove 51, a disc 53, and a connecting rod 55. The circular groove 51 is located at the bottom of the safety plate body 4. A straight groove 52 is formed on the outer wall of the circular groove 51, evenly distributed along the circumference of the circular groove 51. The disc 53 is rotatably connected to the inner wall of the circular groove 51. The diameter of the circular groove 51 is slightly larger than the diameter of the disc 53, with a gap between them to ensure that the disc 53 can rotate flexibly within the circular groove 51. A curved groove 54 is formed on the outer wall of the disc 53. The connecting rod 55 is slidably connected to the inner wall of the straight groove 52. One end of the rod 55 is fixedly connected to a locking block 56, which is slidably connected to the inner wall of the curved groove 54. The width of the curved groove 54 matches the width of the locking block 56, with a gap reserved between them to ensure that the locking block 56 slides in the curved groove 54. The end of the connecting rod 55 away from the locking block 56 is fixedly connected to an arc plate 57. The top of the disc 53 is fixedly connected to a column 8, which moves through the safety plate body 4 and extends upward. The outer wall of the extended end of the column 8 is fixedly connected to a limiting block 9 to prevent the column 8 from coming out of the safety plate body 4. The top of the column 8 and the limiting block 9 is fixedly connected to a knob 10. The outer surface of the knob 10 is provided with anti-slip texture to facilitate the operator to apply force to rotate it.

[0032] Furthermore, a straight groove 6 is provided at the bottom of the safety plate body 4, and a movable block 7 is slidably connected to the inner wall of the straight groove 6. The bottom of the movable block 7 is fixedly connected to the arc plate 57, and the straight groove 6 and the movable block 7 assist the movement of the arc plate 57.

[0033] Furthermore, the top of the safety plate body 4 is provided with a mounting hole 11, which matches the screw 2. The screw 2 moves through the mounting hole 11, and the safety plate body 4 prevents any part such as gaskets and nuts from falling into the filter separator.

[0034] In use, the operator places the filter element body 3 over the screw 2 and rotates the knob 10 to retract the arc plate 57 to the bottom plate of the safety plate body 4. At this time, the diameter of the retracted safety plate body 4 is smaller than the diameter of the top of the filter separator body 1, and the safety plate body 4 can be easily inserted into the filter separator body 1 through the top mounting hole 11 along the screw 2, positioned above the filter element body 3. The operator rotates the knob 10, which drives the column 8 to rotate, thereby causing the disc 53 to rotate in the circular groove 51. As the disc 53 rotates, the locking block 56 slides along the inner wall of the curved groove 54. Due to the connection between the locking block 56 and the connecting rod 55... The connecting rod 55 slides synchronously within the straight groove 52, pushing the arc plate 57 outward along the straight groove 52. At the same time, the moving block 7 at the top of the arc plate 57 slides within the straight groove 6, providing guidance for the movement, until the arc plate 57 is tightly attached to the inner wall of the filter separator body 1. At this point, the movement of the arc plate 57 is complete. Although there is a gap between the two arc plates 57, the gap is not large enough for any part such as a gasket or nut to fall into the filter separator body 1. At this point, the gasket is fitted onto the outer wall of the screw 2, and the nut is rotated above the gasket through the screw 2 to complete the fixation, effectively preventing small parts from falling during the installation process.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
