Description

Technical Field

[0001] The utility model belongs to the technical field of filters and relates to a hookless filter screen support structure for an air conditioner filter. Background Art

[0002] A filter generally refers to a drying filter, and the main function of the drying filter is to filter impurities. Generally speaking, the specifications of the dryer need to be determined according to the refrigeration systems of refrigerators and air conditioners. In the air conditioner refrigeration system, the drying filter is a key auxiliary component, located on the high-pressure liquid pipe between the condenser and the expansion valve. It can absorb the moisture in the refrigerant, filter impurities, prevent ice blockage and dirt blockage, and ensure that the freon does not deteriorate. Its structure includes a desiccant and a filter screen. When situations such as the outer shell getting cold, condensing water, frosting, color change of the sight glass, a large number of bubbles, or replacement of the main components occur, it is necessary to replace it in time. After replacement, it is necessary to detect leaks to avoid refrigerant leakage or air and moisture entering the system.

[0003] When the existing air conditioner filter is in use, the connecting pipes at both ends are connected to the corresponding pipelines of the air conditioner system through a welding treatment method. At this time, most filters are directly suspended and exposed to the outside without other corresponding fixing treatments. During daily use, it is easy to be bumped by external objects and displaced, resulting in cracking and leakage at the welding point. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above problems and provide a hookless filter screen support structure for an air conditioner filter.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hookless filter screen support structure for an air conditioner filter includes a support and a filter. Through holes penetrating the outer wall are provided at both ends of the support, and semi-circular holes are provided at the edges of the support. Connecting pipes are installed at both ends of the filter. An arc-shaped groove is provided on one outer wall of the filter, and a rectangular hole is provided on the right side of the arc-shaped groove. A limiting block is installed on the inner wall of the support, and a support block is installed on the right side of the limiting block. At the same time, a side hole is provided on the inner wall of the support. A side plate is installed on the outer wall of the support. A matching fixing hoop is provided on the semi-circular hole. At the same time, an inner groove is provided on the inner wall of the support. A torsion wheel is installed on the outside of the support. A connecting groove is provided in the inner groove, and a threaded hole is provided below the connecting groove. A fixing block is installed in the inner groove in a matching manner. A rectangular block is installed at the bottom of the fixing block. The top of the fixing block is set as an inclined surface. At the same time, a slot penetrating the outer wall is provided on the back of the fixing block, and a spring is installed in the slot.

[0007] In the above-mentioned air conditioner filter hookless filter screen support structure, the overall outer contour of the support is a semi-cylinder, and at the same time, a semi-cylindrical inner cavity is provided in the support, and the filter is located in this inner cavity.

[0008] In the above-mentioned air conditioner filter hookless filter screen support structure, the round holes and semi-circular holes are symmetrically arranged respectively, the connecting pipe is inserted in the semi-circular holes, and the rectangular holes are symmetrically arranged on both sides of the filter.

[0009] In the above-mentioned air conditioner filter hookless filter screen support structure, the arc-shaped grooves and the limit blocks are symmetrically arranged, and at the same time, the positions of the arc-shaped grooves and the limit blocks correspond to each other. The shape of the limit block is arc-shaped, and the limit block is inserted in the arc-shaped groove.

[0010] In the above-mentioned air conditioner filter hookless filter screen support structure, the outer contour of the support block is arc-shaped, and at the same time, the height of the support block is lower than that of the limit block, and the side hole is located near the bottom of the support.

[0011] In the above-mentioned air conditioner filter hookless filter screen support structure, the side plates are symmetrically arranged, and at the same time, threaded holes are provided on the side plates, and the fixing hoop and the support are connected by bolts.

[0012] In the above-mentioned air conditioner filter hookless filter screen support structure, both the inner groove and the fixing block are arc-shaped, and at the same time, the size of the fixing block is smaller than that of the inner groove. A threaded rod is meshingly installed in the threaded hole, and the threaded rod is connected to the torsion wheel here.

[0013] In the above-mentioned air conditioner filter hookless filter screen support structure, the bottom of the fixing block is rotationally installed in the inner groove through a through pin shaft, and at the same time, one end of the threaded rod abuts against the rectangular block.

[0014] In the above-mentioned air conditioner filter hookless filter screen support structure, the inclined surface slopes downward towards the inside of the support. At the same time, the size at the inclined surface is smaller than that of the rectangular hole, and one end of the inclined surface is an arc surface.

[0015] In the above-mentioned air conditioner filter hookless filter screen support structure, the positions of the slot and the connection slot correspond to each other. The other end of the spring is connected to the inner wall of the connection slot, and at the same time, there is a distance between the bottom of the fixing block and the inner groove.

[0016] Compared with the existing technology, the advantages of the present utility model are as follows:

[0017] When the utility model is in use, rotate the torsion wheel to rotate the threaded rod in the threaded hole outwards, so that the distance between the threaded rod and the rectangular block becomes larger. Then align the arc-shaped groove with the limit block and press it downwards. The outer wall of the filter presses against the inclined surface of the fixed block to make it rotate outwards. At the same time, the spring deforms and compresses to generate elastic force. The end of the inclined surface moves along the outer wall of the filter to the rectangular hole. Under the action of the elastic force, the fixed block rotates inwards and then inserts into the rectangular hole. Then rotate the torsion wheel to make the threaded rod press against the rectangular block. Then fix the bracket at the corresponding position through the side plate. The portable disassembly and assembly filter effectively avoids displacement caused by being knocked by foreign objects and prevents cracking and leakage at the welding place.

[0026] The following further describes the utility model with reference to the drawings.

[0027] As Figures 1-6As shown in the figure, an air-conditioning filter hookless filter screen support structure includes a support 1 and a filter 2. Both ends of the support 1 are provided with round holes 11 penetrating the outer wall. At the same time, semi-circular holes 12 are provided at the edges of the support 1. Connecting pipes 21 are installed at both ends of the filter 2. An arc-shaped groove 22 is provided on one outer wall of the filter 2. A rectangular hole 23 is provided on the right side of the filter 2 in the arc-shaped groove 22. A limiting block 3 is installed on the inner wall of the support 1. A support block 31 is installed on the right side of the limiting block 3. At the same time, a side hole 32 is provided on the inner wall of the support 1. A side plate 33 is installed on the outer wall of the support 1. A matching fixing hoop 4 is provided on the semi-circular hole 12. At the same time, an inner groove 5 is provided on the inner wall of the support 1. A torsion wheel 51 is installed on the outside of the support 1. A connecting groove 52 is provided in the inner groove 5. A threaded hole 53 is provided below the connecting groove 52. A fixing block 6 is installed in the inner groove 5 in a matching manner. A rectangular block 61 is installed at the bottom of the fixing block 6. The top of the fixing block 6 is set as an inclined surface 62. At the same time, a slot 63 penetrating the outer wall is provided on the back of the fixing block 6. A spring 64 is installed in the slot 63.

[0028] In this embodiment, the filter in this case refers to a dryer filter. The dryer filter is not a running component of refrigeration, but an important auxiliary component indispensable in the refrigeration system. The dryer filter is generally installed on the high-pressure liquid pipe from the condenser to the expansion valve to prevent ice blockage and dirt blockage of the system, and is applicable to Freon refrigeration systems with low water solubility. The function of the dryer filter is actually the combination of a dryer and a filter, which can absorb the moisture in the refrigerant.

[0029] Combined with Figure 1 、 Figure 2 As shown in the figure, the overall outer contour of the support 1 is a semi-cylinder. At the same time, a semi-cylindrical inner cavity is provided in the support 1. The filter 2 is located in this inner cavity.

[0030] Furthermore, the inner cavity of the support 1 is larger than the filter 2. The filter 2 needs to be installed in the support 1. At the same time, the support 1 is installed in the corresponding place through the side plate 33 on the outer wall.

[0031] Combined with Figure 1 、 Figure 2 As shown in the figure, the round holes 11 and the semi-circular holes 12 are symmetrically arranged respectively. The connecting pipes 21 are inserted into the semi-circular holes 12. The rectangular holes 23 are symmetrically arranged on both sides of the filter 2.

[0032] Furthermore, during installation, the connecting pipes 21 are located in the semi-circular holes 12. The size of the connecting pipes 21 just fits the semi-circular holes 12. The internal size of the semi-circular holes 12 accounts for half of the connecting pipes 21. Therefore, half of the connecting pipes 21 are located outside the semi-circular holes 12.

[0033] Combined with Figure 1 、Figure 2 As shown, the arc-shaped groove 22 and the limit block 3 are symmetrically arranged, and at the same time, the positions of the arc-shaped groove 22 and the limit block 3 correspond to each other. The shape of the limit block 3 is arc-shaped, and the limit block 3 is inserted into the arc-shaped groove 22.

[0034] Furthermore, when the filter 2 is installed in the bracket 1, the arc-shaped groove 22 will be seated on the limit block 3. The limit block 3 not only plays a role in guiding and limiting the installation of the filter 2, but also fixes the position of the filter 2 to prevent it from shaking.

[0035] Combined with Figure 1 、 Figure 2 As shown, the outer contour of the support block 31 is arc-shaped, and at the same time, the height of the support block 31 is lower than that of the limit block 3. The side hole 32 is located near the bottom of the bracket 1.

[0036] Furthermore, since the arc-shaped groove 22 will be seated on the limit block 3, the height of the support block 31 is lower than that of the limit block 3. The height difference between the support block 31 and the limit block 3 is exactly the same as the depth of the arc-shaped groove 22. Thus, the support block 31 is in contact with the outer wall of the filter 2.

[0037] Combined with Figure 1 、 Figure 2 As shown, the side plates 33 are symmetrically arranged, and at the same time, threaded holes 53 are provided on the side plates 33. The fixing hoop 4 and the bracket 1 are connected by bolts.

[0038] Furthermore, the position of the bracket 1 is fixed by the side plates 33. The fixing hoop 4 cooperates with the semi-circular hole 12 to fix the position of the connecting pipe 21 to prevent it from shaking. The round holes 11 at both ends and the side holes 32 play a role in draining water to prevent water accumulation in the bracket 1.

[0039] Combined with Figure 1 、 Figure 2 As shown, both the inner groove 5 and the fixing block 6 are arc-shaped, and at the same time, the size of the fixing block 6 is smaller than that of the inner groove 5. A threaded rod is meshingly installed in the threaded hole 53, and here the threaded rod is connected to the torsion wheel 51. The bottom of the fixing block 6 is rotatably installed in the inner groove 5 through a through pin, and one end of the threaded rod abuts against the rectangular block 61. The inclined surface 62 slopes downward towards the inside of the bracket 1, and at the same time, the size of the inclined surface 62 is smaller than that of the rectangular hole 23, and one end of the inclined surface 62 is provided with an arc surface. The positions of the slot 63 and the connecting groove 52 correspond to each other. The other end of the spring 64 is connected to the inner wall of the connecting groove 52, and at the same time, there is a gap between the bottom of the fixing block 6 and the inner groove 5.

[0040] Furthermore, the inclined surface 62 of the fixing block 6 is hook-shaped. During installation, it is necessary to rotate the torsion wheel 51 first to move the threaded rod in the threaded hole 53 outward so that the distance between the threaded rod and the rectangular block 61 becomes larger. Therefore, the fixing block 6 can rotate outward based on the pin axis at the bottom. By using the threaded rod to support the rectangular block 61, the fixing block 6 cannot rotate based on the pin axis, thereby fixing its shape and allowing the inclined surface 62 to be inserted into the rectangular hole 23 to fix the filter 2.

[0041] The working principle of the utility model is:

[0042] First, fix the bracket 1 in the corresponding position through the engaging bolts in the side plate 33, then remove the fixing hoop 4, and then rotate the twist wheel 51 counterclockwise to move the threaded rod in the threaded hole 53 outward, so that the distance between the threaded rod and the rectangular block 61 becomes larger, and now the fixing block 6 has space to rotate based on the pin shaft.

[0043] Adjust the arc groove 22 of the filter 2 to a position in the same direction as the limit block 3, and then press the filter 2 toward the inside of the bracket 1. At this time, the filter 2 is against the outer wall of the fixing block 6, and then the fixing block 6 rotates outward based on the pin shaft at the bottom, and the internal spring 64 is deformed and compressed to generate elastic force, and then the end face at the inclined surface 62 moves along the outer wall of the filter 2 to the rectangular hole 23. Then, under the action of the elastic force of the spring 64, the fixing block 6 rotates inward and then the inclined surface 62 is inserted into the rectangular hole 23, and then the twist wheel 51 is rotated to make the threaded rod against the rectangular block 61. At this time, one side of the fixing block 6 and the filter 2 are meshed with each other, so the fixing block 6 cannot rotate based on the pin shaft at the bottom, the arc groove 22 is located on the limit block 3, the support block 31 and the filter 2 are fitted, the connecting pipe 21 falls into the semicircular hole 12, and the fixing hoop 4 is installed at the semicircular hole 12, and the fixing hoop 4 cooperates with the semicircular hole 12 to fix the connecting pipe 21.

[0044] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the spirit of the present invention.

[0045] Although this article uses more terms such as 1, bracket; 11, round hole; 12, semicircular hole; 2, filter; 21, connecting pipe; 22, arc groove; 23, rectangular hole; 3, limit block; 31, support block; 32, side hole; 33, side plate; 4, fixing hoop; 5, inner groove; 51, twist wheel; 52, connecting groove; 53, threaded hole; 6, fixing block; 61, rectangular block; 62, inclined plane; 63, slot; 64, spring, etc., it does not exclude the possibility of using other terms.
