Description

Technical Field

[0001] The present invention relates to the technical field of assembly auxiliary equipment, and in particular to an air filter buckle assembly tool. Background Art

[0002] To facilitate the installation of the filter element within the housing, common air filters on the market all utilize a structure consisting of an upper and lower housing. These two housings can be connected using screws around the circumference, or hinged on one side with a metal arc-shaped elastic clip around the circumference for fastening.

[0003] When assembling snap-on air filters, due to the high airtightness requirements and tightness of the snap-on fastener, the snap-on fastener requires a high snap-on force and a small deformation, making it difficult to fasten. This requires manual effort on the curved portion of the snap-on fastener to straighten it before snapping it into place on the air filter, resulting in low assembly efficiency. Furthermore, because the snap-on fastener is rigid and thin, the worker must exert a significant amount of force to close it, resulting in high labor intensity and significant wear and tear on the worker's hands. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art, and particularly innovatively proposes an air filter clip assembly tool to improve assembly efficiency and save manpower.

[0005] In order to achieve the above-mentioned objectives of the present invention, the present invention provides an air filter buckle assembly tool, including a base plate, a contoured seat for placing the air filter and matching the bottom of the air filter, a buckle mechanism corresponding to the buckle at the buckle joint of the upper and lower shells of the air filter, the buckle mechanism includes a column, the top of the column is rotatably connected to a lever structure for prying up the buckle through a pin, the prying end of the lever structure is arranged close to the contoured seat, and the end is rotatably connected to a pressure roller extending laterally left and right, the pressure roller can rotate and extend between the contoured seat on this side and the corresponding air filter bayonet, and is used to push the buckle to be buckled at the buckle joint of the upper and lower shells.

[0006] In the above scheme: the lever structure includes a door-shaped prying piece, the two legs of the prying piece are rotatably connected to the column through a rotating shaft, and the column is located between the two legs of the prying piece, and the pressure roller is rotatably connected to the open ends of the two legs of the prying piece through the rotating shaft.

[0007] In the above solution: a ring groove matching the buckle is provided in the middle of the pressure roller, which is convenient for limiting the position of the buckle, improving the stability when prying, and preventing left and right deviation.

[0008] In the above solution, a connecting rod is connected between the prying pieces on the same side, and simultaneously drives the snapping mechanism on the same side to snap the upper and lower shells.

[0009] In the above scheme: the contoured seat includes a front half seat and a rear half seat arranged at an interval of front and rear, and the front half seat and the rear half seat are provided with a groove matching the lower shell of the air filter on the side opposite to each other, so that the middle part of the lower shell is suspended, and the top of the front half seat is also recessed with a notch for the mounting ears and air outlet on the front side of the lower shell to rest on.

[0010] In the above solution, a recessed groove is provided on the top of the contoured seat portion located just below the buckle, so that the pressure roller can rotate to just below the buckle.

[0011] In the above solution, only the rear half seat is located below the air filter buckle, and the height of the rear half seat is lower than that of the front half seat.

[0012] In the above solution: the bottom plate is provided with handles located on the left and right sides of the contoured seat, and the bottom side of the bottom plate is provided with foot pads.

[0013] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects: the provided contoured seat can effectively fix the air filter, and the provided lever structure can quickly and effectively pry up the buckle, saving manpower. The buckle is pushed close to the air filter by the pressure roller, and the middle of the curved buckle is slightly flattened by the pressure roller, so that the top of the buckle naturally moves above the corresponding position of the air filter, thereby locking it. Manual straightening of the buckle is no longer required, thereby improving work efficiency and reducing work intensity and difficulty. The pressure roller is configured to rotate, which can form rolling friction with the buckle, improving its protection and making prying smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0019] like Figures 1 to 4The figure shows an air filter snap-on assembly tool, comprising a base plate 1 with a shaped seat 2 that matches the bottom of the air filter. The base plate 1 is provided with handles on either side of the shaped seat 2 to facilitate movement of the assembly tool. The base plate 1 is provided with foot pads 1b on the underside, each with a silicone anti-slip layer on its bottom. The shaped seat 2 comprises a front half seat 2a and a rear half seat 2b, spaced apart from each other. The opposing sides of the front half seat 2a and the rear half seat 2b are each provided with a groove that matches the lower housing of the air filter. The front half seat 2a and the rear half seat 2b only secure the front and rear sides of the lower housing, leaving the middle portion of the lower housing suspended in the air. The top of the front half seat 2a also has a recessed slot for the mounting ears and air outlet on the front side of the lower housing to rest on.

[0020] A snapping mechanism is provided on the base plate 1, corresponding to the snaps a at the joints between the upper and lower housings of the air filter. In this embodiment, only two snapping mechanisms are provided on the left and right sides of the rear half of the seat 2b. These mechanisms include a column 3, the top of which is provided with a lever structure 4 for prying up the snaps a. Specifically, the lever structure 4 comprises a door-shaped prying member, the middle portion of which is pivotally connected to the column 3 via a rotating shaft. The column 3 is located between the prying member's legs, and the ends of the prying member's legs extend to the front of the column 3 and are pivotally connected to a laterally arranged pressure roller 5. Preferably, the lever structure 4 is a force-saving lever structure, meaning that the front half of the prying member's hinge is shorter than the rear half of the hinge. By pressing the rear side of the prying member downward, the pressure roller 5 is pried upward, thereby pressing the snaps a against the air filter and locking the top of the snaps a into place. A connecting rod 6 connects the two prying members, simultaneously driving the locking mechanism on the rear side of the rear half 2b to push the buckle a to lock the upper and lower shells. This rational arrangement is convenient and quick, allowing buckle a to be fastened in one go, thereby improving assembly efficiency. To prevent the buckle a from shifting left or right during the prying process, the pressure roller 5 is preferably provided with a ring groove 5a in the middle that matches the buckle a, thus limiting its position and improving stability during prying.

[0021] The top portion of the contoured seat 2, located directly below the buckle a, is provided with a recessed clearance groove, allowing the pressure roller 5 to rotate below the buckle a. The buckle a of the air filter corresponding to this embodiment is located at the rear side of the air filter. Therefore, for a more aesthetically pleasing appearance, the height of the entire rear half seat 2b is set lower than that of the front half seat 2a, without a separate recessed clearance groove.

[0022] The prying end of the lever structure 4 is provided with a counterweight block which makes it be at a low position under normal conditions, so that the pressure roller 5 is at the lowest position under normal conditions, making it easy to pry up the buckle a.

[0023] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
