[0002] The air tightness of doors and windows refers to the ability of external doors and windows to prevent air infiltration when they are normally closed. It is one of the important criteria for judging whether the doors and windows are tightly sealed and whether there is air leakage.

[0003] The utility model application number: CN202223078014.4 (publication number: CN218994651U) discloses a door and window air tightness detection device, comprising a support base, a loading frame, a detection cover, and a detection medium. The support base is provided with a detection slot; the loading frame is arranged around the detection slot, and the port of the loading frame away from the ground can be covered with a door and window; the detection cover is arranged above the detection slot away from the ground, the detection cover is used to cover the top of the door and window away from the ground, and the detection cover is provided with an inflation device to inflate the detection cover;

[0004] The above patent places the doors and windows that need to be inspected on the top of the loading frame, and the inspection cover presses the top of the doors and windows and encloses the doors and windows to form an inflatable cavity. However, due to the lack of positioning function, the doors and windows may be offset and placed incorrectly, resulting in uneven force and errors during inspection. Utility Model Content

[0005] In view of this, the utility model provides a window air tightness detection device, which is used to solve the technical problem that doors and windows may be offset due to the lack of positioning function, resulting in misplacement and uneven force, which may cause errors in detection.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a window air tightness detection device, comprising four support columns, wherein a top plate is fixedly mounted on the top of each support column, a support base is fixedly mounted on each support column, a detection frame for placing a window is slidably connected to the support base, and the detection frame has a detection cavity;

[0008] A telescopic cylinder is fixedly mounted on the top plate, the movable end of the telescopic cylinder extends downward and an adjustment plate is fixedly mounted on the end thereof, and a detection cover for pressing the window is fixedly mounted on the adjustment plate;

[0009] The detection frame is connected to two push plates A for horizontal sliding and two push plates B for vertical sliding.

[0010] On the basis of the above technical solution, the window air tightness detection device of the present invention can also be improved as follows:

[0011] Furthermore, a double-headed cylinder A is fixedly mounted on the bottom wall of the support base, the movable end of the double-headed cylinder A is arranged horizontally and a bending rod A is fixedly mounted on the end thereof, two sliding grooves A are arranged horizontally through the support base, and the bending rod A is slidably connected in the sliding grooves A on the same side;

[0012] A push plate A is fixedly mounted on the ends of the bending rods A on both sides that are close to each other.

[0013] Furthermore, a double-headed cylinder B is fixedly mounted on the bottom wall of the support base, the movable end of the double-headed cylinder B is longitudinally arranged and a bent plate B is fixedly mounted on the end thereof, two sliding grooves B are longitudinally opened on the support base, and the bent rod A is slidably connected in the sliding grooves B on the same side;

[0014] A push plate B is fixedly installed on the ends of the bending plates B on both sides that are close to each other.

[0015] Furthermore, two slide rails are fixedly mounted on the support seat, and sliders are slidably connected to the detection frame. The sliders are symmetrically fixedly mounted on the bottom wall of the detection frame.

[0016] Furthermore, a positioning groove is provided in the middle of the bottom wall of the detection frame, and a rising cylinder is fixedly installed on the top wall of the support seat. The movable end of the rising cylinder extends upward and a positioning block is fixedly installed on the end to be plugged into the positioning groove. The positioning block is located at the center of the detection cover.

[0017] Furthermore, a positioning plate located on the support seat is fixedly mounted on the rear end of the slide rail.

[0018] Compared with the prior art, the beneficial effects of the window air tightness detection device provided by the present invention are:

[0019] By setting a sliding connection detection frame, it is convenient to move the window to be detected to a specified position for detection.

[0020] By setting the positioning blocks and positioning slots, it is easy to position the detection frame, avoiding the deviation of the window during detection, or the inconsistent positions of the same batch of windows, which affects the detection effect.

[0021] By setting the push plate A and the bending plate B, the two push plates A move simultaneously under the action of the double-headed cylinder A, so that the window is centered in the horizontal position, and the two bending plates B move simultaneously under the action of the double-headed cylinder B, so that the window is centered in the vertical position; when the same batch of windows are individually tested, they can be located in the same position each time, with uniform force and improved detection accuracy.

[0022] By setting the sliding connection between the push plate A and the bending plate B, the fit between the detection cover and the window body is prevented from being affected during detection. BRIEF DESCRIPTION OF THE DRAWINGS
