DETAILED DESCRIPTION

[0021] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] Example:

[0023] The accompanying drawings show a specific embodiment of a filter device for preventing a barrel cover from tipping over according to the present invention. Figure 1 、 Figure 2 、 Figure 3 The invention mainly comprises a barrel body 1 and a barrel cover 2. The barrel body 1 is provided with a fixed support 3, which is arranged vertically. The lower end of the fixed support 3 extends to the lower part of the barrel body 1, and the upper end of the fixed support 3 extends to the upper part of the barrel cover 2. The fixed support 3 is fixedly connected to the barrel body 1 by two sets of connecting support plates 4 arranged vertically. Each set of connecting support plates 4 includes two support plates, and the two support plates of the same set are symmetrically arranged on both sides of the fixed support 3.

[0024] The upper portion of the fixed support 3 is connected to the barrel cover 2 on both sides via hinge plates 5. One end of each hinge plate 5 is rotatably mounted on the upper portion of the fixed support 3 via hinge shafts 6, and the other end of each hinge plate 5 is fixedly connected to the barrel cover 2. The upper portion of the fixed support 3 has a cavity 3a defined therein, and the inner ends of the two hinge shafts 6 are disposed within the side walls of the cavity 3a.

[0025] A telescopic rod positioning assembly 7 is provided on the upper portion of the fixed support 3, and the telescopic rod positioning assembly 7 is fixedly mounted on the fixed support 3 via a mounting plate 8. The telescopic rod positioning assembly 7 is located outside the hinge plate 5 and includes an outer sleeve 701 arranged obliquely and a telescopic positioning rod 702 which is telescopically arranged inside the outer sleeve 701. Figure 2 As shown, the outer sleeve 701 is provided with a sliding groove 701a extending vertically therethrough, a tension spring 703 is provided in the sliding groove 701a, the lower end of the tension spring 703 is connected to the bottom of the sliding groove 701a, the telescopic positioning rod 702 comprises an upper end 7021, an intermediate connecting rod 7022, and a lower end 7023 connected in sequence, the upper end 7021 and the intermediate connecting rod 7022 being slidably arranged in the sliding groove 701a, the tension spring 703 being sleeved on the outside of the intermediate connecting rod 7022, the upper end of the tension spring 703 being abutted against the lower end of the upper end 7021, and the lower end 7023 being arranged on the outside of the outer sleeve 701. Pulling the lower end 7023 can drive the upper end 7021 to retract into the outer sleeve 701. After releasing the lower end 7023, the upper end 7021 is ejected and reset due to the action of the tension spring 703.

[0026] The telescopic positioning rod 702 of the telescopic rod positioning assembly 7 is in contact with the hinge plate 5 and can be telescoped as the hinge plate 5 rotates, thereby achieving positioning and locking of the hinge plate 5 and the barrel cover 2.

[0027] A support limit block 9 is provided at the top of the fixed support 3, and the two ends of the support limit block 9 extend to the outside of the two sides of the fixed support 3 respectively. The hinge plate 5 can be rotated and overlapped on the support limit block 9. The support limit block 9 is used to support and position the hinge plate 5, thereby supporting the barrel cover 2.

[0028] A movable counterweight 10 is slidably installed in the barrel cover 2. Figure 3 The lid 2 has a downwardly sloping chamber 2a, within which a movable counterweight 10 is movably mounted. A buffer spring 13 is provided at the bottom of the chamber 2a, one end of which is fixedly connected to the bottom of the chamber 2a. When the lid 2 is normally closed, the movable counterweight 10 falls to the bottom of the chamber 2a under its own weight, with the buffer spring 13 acting as a buffer.

[0029] A linkage bent rod 11 is also rotatably mounted on the upper portion of the fixed support 3. The linkage bent rod 11 is partially located within the cavity 3a. A hinged support 14 is provided on the exterior of the upper portion of the fixed support 3, and the linkage bent rod 11 is rotatably mounted on the hinged support 14. The upper portion of the fixed support 3 is provided with a side movable hole 3b and an upper movable hole 3c that communicate with the cavity 3a and are used to mount the linkage bent rod 11. The outer end of the linkage bent rod 11 is located outside the cavity 3a and abuts against the upper portion of the fixed support 3. The inner end of the linkage bent rod 11 is located inside the cavity 3a and can be extended from the upper movable hole 3c to the exterior of the fixed support 3 by rotation.

[0030] A connecting block 12 is provided between the two hinged plates 5. The connecting block 12 has a fitting recess 12a that mates with the linkage curved rod 11. When the lid 2 is opened, the movable counterweight 10 is driven to extend from the oblique cavity 2a and, through the movable counterweight 10, press down on one end of the linkage curved rod 11, causing the other end of the linkage curved rod 11 to tilt and reversely press against the connecting block 12, thereby further positioning the lid 2.

[0031] When the filter device of the present invention is used, it is combined with Figure 4 、 Figure 5 When the lid 2 is initially opened, the hinged plate 5 rotates with the lid 2. Under the action of the hinged plate 5, the telescopic positioning rod 702 is pressed downward. At the same time, the movable counterweight 10 in the lid 2 will gradually move downward and extend to the outside of the lid 2, thereby lowering the center of gravity. Figure 6 、 Figure 7As the bucket cover 2 continues to rotate, the hinged plate 5 continues to rotate until it is offset from the telescopic positioning rod 702, and then the telescopic positioning rod 702 releases pressure and springs up, which plays a positioning and supporting role for the hinged plate 5, so that the hinged plate 5 and the bucket cover 2 will not fall forward. At the same time, the hinged plate 5 rotates and overlaps the support limit block 9, which prevents the hinged plate 5 and the bucket cover 2 from falling backward, thereby achieving effective positioning and fixation of the bucket cover 2; the rotation of the bucket cover 2 will also drive the movable counterweight block 10 to rotate, and the movable counterweight block 10 contacts the linkage bent rod 11, pressing down one end of the linkage bent rod 11, so that the other end of the linkage bent rod 11 is tilted between the two hinged plates 5, and reversely presses against the fitting recess 12a of the connecting block 12, thereby further positioning and fixing the hinged plate 5 and the bucket cover 2, ensuring the stability of the bucket cover 2 after opening, and preventing it from falling.

[0032] When closing the lid, you only need to pull down the telescopic positioning rod 702 to release the lock of the hinged plate 5, and then turn the barrel lid 2 downward to close the lid. The operation is simple and labor-saving. The telescopic positioning rod 702 can be reset under the action of the tension spring 703 to prepare for the next opening of the lid. During the closing process, the rotation of the hinged plate 5 will drive the connection block 12 to rotate. The connection block 12 applies reverse force to the linkage curved rod 11, helping the linkage curved rod 11 to retract into the cavity 3a. The movable counterweight block 10 is separated from the linkage curved rod 11 and falls back to the bottom of the inclined cavity 2a under its own weight under the action of the inclined cavity 2a. The buffer spring 13 is used to reduce the force. Finally, the linkage curved rod 11 returns to its original position under the action of its own gravity. Figure 3 status, preparing for the next opening.

Their purpose is to enable those skilled in the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any modifications made within the spirit of the main technical solution of the present invention are intended to be encompassed within the scope of protection of the present invention.
