Description

Technical Field

[0001] The utility model relates to the technical field of airtightness detection, in particular to a fixing device for detecting the airtightness of doors and windows. Background Art

[0002] The airtightness detection of doors and windows refers to a standardized operation for testing the airtight performance of door and window products. By detecting the airtightness of door and window products, their sealing performance can be evaluated to ensure that the products meet relevant quality standards and requirements. Moreover, qualified door and window products can effectively improve the energy consumption efficiency of buildings, reduce energy waste, and enhance indoor comfort. Therefore, the airtightness detection standard for doors and windows is of great significance for improving the building energy conservation level and ensuring the quality of residents' lives.

[0003] Currently, when detecting the airtightness of doors and windows on-site, first, the film needs to be fixed on the surrounding walls of the doors and windows with tape, then a hole is opened, the detection tube and the air supply tube are inserted, and then the film is fixed to the detection tube and the air supply tube with tape.

[0004] There are many existing fixing devices that can fix the film to the surrounding walls of the doors and windows without using tape. For example, an assembled airtightness detection device for houses with the publication number of CN220794559U and a sealing device for detecting the airtightness of doors and windows with the publication number of CN220304739U in the prior art are both like this. However, a large amount of tape is still needed for the connection between the detection tube, the air supply tube and the film, which will cause waste and pollution. When the film is fixed to the wall by the traditional tape method, after the air supply tube, the detection tube and the film are connected, a downward dragging force will be generated due to gravity. Therefore, the probability of the film falling off will also increase. For this reason, improvements are proposed. Summary of the Utility Model

[0005] The utility model aims to solve the defects existing in the prior art and provides a fixing device for detecting the airtightness of doors and windows.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a fixing device for detecting the airtightness of doors and windows, including a film, and pressing covers and pressing rings are respectively abutted against both sides of the outer surface of the film;

[0007] A circular nut is rotatably connected to the inner surface of the pressing cover, a long rod is fixedly installed at the top of the pressing cover, a knob is arranged through one side of the outer surface of the long rod, and a screw telescopic part is jointly installed between the knob and the long rod;

[0008] A fixing cover is fixedly connected to one side of the outer surface of the pressing ring, and a detection tube connector and an air supply tube connector are fixedly penetrated through one side of the outer surface of the fixing cover;

[0009] On the other side of the outer surface of the pressure ring, a hollow screw is fixedly connected, and the hollow screw penetrates through the film, and a circular nut is threadedly sleeved on the outer surface of the hollow screw.

[0010] Furthermore, the screw telescopic member includes a first screw and a second screw, and the first screw and the second screw are respectively fixedly installed on the outer walls on both sides of the knob. The outer surfaces of the first screw and the second screw are both threadedly sleeved with movable rods, and the movable rods penetrate through the long rod and are slidably connected thereto. The cross-section of the movable rod is in a direction. When it slides with the long rod, the long rod has a limiting effect on the movable rod, which can prevent the movable rod from rotating when the first screw and the second screw rotate, thereby ensuring the stability of the movement of the movable rod.

[0011] Furthermore, the thread directions on the outer surfaces of the first screw and the second screw are opposite. Two support blocks are rotatably sleeved on the outer surfaces of the first screw and the second screw, and the support blocks are fixedly connected to the long rod. The support blocks have a supporting effect on the first screw and the second screw, which is beneficial to the installation of the first screw and the second screw.

[0012] Furthermore, the test tube connecting member includes a thin connecting tube, and the thin connecting tube is fixedly penetrated with the fixed cover. A first hose clamp is sleeved on the outer surface of the thin connecting tube. The setting of the first hose clamp is beneficial to quickly fixedly connect the test tube and the thin connecting tube.

[0013] Furthermore, the air supply pipe connecting member includes a thick connecting tube, and the thick connecting tube is fixedly penetrated with the fixed cover. A second hose clamp is sleeved on the outer surface of the thick connecting tube. The setting of the second hose clamp is beneficial to quickly fixedly connect the air supply pipe and the thick connecting tube.

[0014] Furthermore, annular rubber gaskets are fixedly installed on the adjacent sides of the outer surfaces of the pressure cover and the pressure ring to ensure the extrusion sealing effect of the pressure cover and the pressure ring on the film.

[0015] Furthermore, anti-slip patterns are provided on the outer surfaces of the circular nut and the knob to increase the friction on the outer surfaces of the circular nut and the knob and prevent slipping during use.

[0016] The beneficial effects of the present utility model:

[0017] When the present utility model is in use, for this kind of door and window airtightness detection fixing device, through the arranged pressure cover, pressure ring, circular nut, long rod, knob, screw telescopic member, test tube connecting member, air supply pipe connecting member and hollow screw, the film can be hermetically connected to the test tube and the air supply pipe without using tape connection, avoiding waste and pollution. At the same time, it also has a supporting effect. After being fixed, it can prevent a downward dragging force from being generated on the film, improving the fixing effect of the film.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0025] As Figures 1 to 3 shown, it relates to a fixing device for detecting the airtightness of doors and windows, including a film 1. On both sides of the outer surface of the film 1, a pressing cover 7 and a pressing ring 12 are respectively abutted. On the adjacent side of the outer surfaces of the pressing cover 7 and the pressing ring 12, annular rubber pads are fixedly installed. After the pressing cover 7 and the pressing ring 12 are assembled, the annular rubber pads can ensure the sealing performance of their abutment with the film 1.

[0026] The inner surface of the pressing cover 7 is rotatably connected with a circular nut 6. The top of the pressing cover 7 is fixedly installed with a long rod 3. One side of the outer surface of the long rod 3 is provided with a knob 4 penetrating through it. A screw telescopic member is jointly installed between the knob 4 and the long rod 3. The screw telescopic member includes a first screw rod 14 and a second screw rod 16, and the first screw rod 14 and the second screw rod 16 are respectively fixedly installed on the outer walls on both sides of the knob 4. The outer surfaces of both the first screw rod 14 and the second screw rod 16 are threadedly sleeved with movable rods 2, and the movable rods 2 penetrate through the long rod 3 and are slidably connected therewith. The thread directions on the outer surfaces of the first screw rod 14 and the second screw rod 16 are opposite. When the first screw rod 14 and the second screw rod 16 are simultaneously driven to rotate by the knob 4, the two movable rods 2 can be driven to move away from each other. The outer surfaces of the first screw rod 14 and the second screw rod 16 are rotatably sleeved with two support blocks 15, and the support blocks 15 are fixedly connected with the long rod 3. Bearings are not provided at the rotational connection positions of the first screw rod 14, the second screw rod 16 and the adjacent support blocks 15. Instead, annular grooves are formed on the outer surfaces of the first screw rod 14 and the second screw rod 16. The two inner walls on both sides of the annular grooves are abutted against the outer walls on both sides of the support blocks 15, so that the effect of limiting rotation can be achieved through the annular grooves.

[0027] One side of the outer surface of the pressing ring 12 is fixedly connected with a fixed cover 10. One side of the outer surface of the fixed cover 10 is fixedly penetrated with a detection tube connecting piece and an air supply tube connecting piece. The detection tube connecting piece includes a thin connecting tube 9, and the thin connecting tube 9 is fixedly penetrated with the fixed cover 10. A first hose clamp 8 is sleeved on the outer surface of the thin connecting tube 9. When connecting the detection tube, loosen the first hose clamp 8, sleeved the detection tube on the outer surface of the thin connecting tube 9, and then tighten the first hose clamp 8. The air supply tube connecting piece includes a thick connecting tube 11, and the thick connecting tube 11 is fixedly penetrated with the fixed cover 10.

The circular nut 6 is threadedly sleeved on the outer surface of the hollow screw 5. The cooperation between the circular nut 6 and the hollow screw 5 is conducive to driving the pressing ring 12 to approach the pressing cover 7.

[0029] Anti-slip patterns are provided on the outer surfaces of both the circular nut 6 and the knob 4 to increase the friction force on the outer surfaces of the circular nut 6 and the knob 4 and avoid slipping during use.

[0030] Working principle: First, make a hole in the film 1, pass the hollow screw 5 through this hole, then put the circular nut 6 on the surface of the hollow screw 5 and rotate it so that the pressing cover 7 approaches the pressing ring 12 until it is in close contact with the film 1. Then rotate the knob 4, and the knob 4 drives the first screw 14 and the second screw 16 to rotate at the same time. The first screw 14 and the second screw 16 respectively drive the movable rods 2 connected to them to move, so that the two movable rods 2 move away from each other until the movable rods 2 are in contact with the inner wall of the door or window. Then perform the fixing operation on the film 1. After completion, then install the detection pipe and the air supply pipe. When connecting the detection pipe, loosen the first hose clamp 8, put the detection pipe on the outer surface of the thin connecting pipe 9, and then tighten the first hose clamp 8. When connecting the air supply pipe, loosen the second hose clamp 13, put the air supply pipe on the outer surface of the thick connecting pipe 11, and then tighten the second hose clamp 13.
