Description

Technical Field

[0001] This utility model relates to the field of screen technology, and more specifically to an installation frame and screen. Background Technology

[0002] Most existing screen windows have a fixed four-sided frame structure, consisting of four corner brackets and frame profiles combined into one piece, with the corner brackets and frame profiles secured by screws.

[0003] However, traditional framed window screens, when purchased from stores or online, require additional installation tools such as screws to be fixed to windows. The process is cumbersome and inconvenient, and once fixed, the position is locked, resulting in poor product flexibility and convenience. Therefore, a new type of mounting frame is needed to solve these problems. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A mounting frame includes a frame body with a spring hook. The spring hook includes a torsion spring body with a first torsion arm and a second torsion arm. The first torsion arm is inserted into or fixed to the frame body. The second torsion arm is located outside the frame body and has a bend for abutting against the edge of a window.

[0006] The present invention is further configured such that: the hanging frame body has an opening for installing a mesh screen, and the hanging frame body is provided with spring hooks on both the upper and lower sides of the opening; the bent part of the spring hook located above the opening extends upward from the second torsion arm, and the bent part of the spring hook located below the opening extends downward from the second torsion arm.

[0007] The present invention is further configured such that: the hanging frame body is provided with spring hooks on both the left and right sides of the opening, the second torsion arm of the spring hook extends horizontally toward the middle of the opening, and the bent part is provided at the end of the second torsion arm away from the torsion spring body.

[0008] The present invention is further configured such that when the second torsion arm rotates away from the hanging frame body, the second torsion arm has a tendency to rotate towards the hanging frame body.

[0009] The present invention is further configured such that: the hanging frame body is a rectangular square frame, the hanging frame body includes four prongs located at the four corners, and the two ends of the prongs are respectively connected to the frame profile.

[0010] The present invention is further configured such that: the pin is right-angled, and the two ends of the pin are respectively inserted into the frame profile and fixed by friction.

[0011] The present invention is further configured such that: the torsion spring body is disposed at the part where the pin passes through the frame profile, and the torsion spring body is covered by the pin and the frame profile to achieve horizontal positioning; a positioning groove is formed on the pin along the horizontal direction; the first torsion arm passes through the positioning groove to achieve vertical positioning; and there is a notch between the pin and the frame profile for the second torsion arm to pass through.

[0012] In addition, this utility model also proposes a screen window, including the above-mentioned mounting frame, wherein the opening of the mounting frame body is covered with a screen.

[0013] Compared with the prior art, the present invention has at least the following advantages:

[0014] 1. When installing a screen window, the second torsion arm of the spring hook can be bent outwards, allowing the bent part to abut against the edge of the window through the elastic force of the torsion spring. That is, the frame body and the bent part clamp the edge of the window in the middle, thus installing the screen window. Because it is snapped together by the elastic force of the torsion spring, it can be adapted to be installed on windows of different thicknesses. No additional tools are required during installation, which solves the problem of the cumbersome and complicated installation steps of existing screen window frames and improves the flexibility and convenience of the product.

[0015] 2. Spring hooks are installed at both the top and bottom of the frame body. When the bent parts engage with the window edge, the upper and lower limits of the frame body are achieved, and the frame body can also move left and right. By extending the second torsion arm towards the middle of the frame body, users can more easily pry the second torsion arm open outwards during screen installation.

[0016] 3. The frame body is composed of inserts and frame profiles. The two ends of the inserts can be inserted into the frame profiles by applying external force to fix them. This allows the frame body to be packaged separately during transportation, which solves the problem that traditional integrated frame screens increase transportation costs due to their large packaging volume. Also, integrated frame screens are prone to twisting and deformation during transportation due to their large area, resulting in defects and inability to be installed or used.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] A type of mounting frame, such as Figures 1 to 4 As shown, the device includes a frame body 1, on which a spring hook 2 is provided. The spring hook 2 includes a torsion spring body 201, which has a first torsion arm 202 and a second torsion arm 203. The torsion spring body 201 is vertically arranged. The first torsion arm 202 and the second torsion arm 203 are located at the top and bottom of the torsion spring body 201, respectively. The first torsion arm 202 is inserted into the frame body 1 or fixed to the frame body 1. The second torsion arm 203 is located on the outside of the frame body 1. The second torsion arm 203 is provided with a bending part 204, which is used to abut against the edge of the window 7.

[0028] The first torsion arm 202 is connected to the frame body 1. When the second torsion arm 203 rotates away from the frame body 1, it has a restoring force under the action of the torsion spring, meaning it tends to rotate towards the frame body 1. Therefore, when installing the frame body 1, the second torsion arm 203 is bent outwards, causing the bent part 204 to abut against the edge of the window 7 through the spring force. In other words, the frame body 1 and the bent part 204 clamp the edge of the window 7 in the middle, thus achieving the installation of the screen without the need for screws.

[0029] The frame body 1 has an opening 3 in the middle for installing the screen 6. In this embodiment, the frame body 1 is provided with spring hooks 2 on both the upper and lower sides of the opening 3. The bent portion 204 of the spring hook 2 located above the opening 3 extends upward from the second torsion arm 203, and can be set vertically upward or inclined upward. The bent portion 204 of the spring hook 2 located below the opening 3 extends downward from the second torsion arm 203, and can be set vertically downward or inclined downward. By engaging with the edge of the window 7 through the bent portions 204 of the two spring hooks 2, the upper and lower limits of the frame body 1 are achieved. In this embodiment, the bent portion 204 of the upper spring hook 2 is inclined upward, and the bent portion 204 of the lower spring hook 2 is inclined downward, which increases the contact length with the edge of the window 7 at the same vertical height, making installation easier.

[0030] In other embodiments, at least a spring hook 2 needs to be provided at the bottom. Although the upper and lower limits cannot be achieved in this case, the installation can still be completed.

[0031] In this embodiment, spring hooks 2 are provided on both the left and right sides of the opening 3 of the hanging frame body 1, making the installation of the hanging frame body 1 more stable. Furthermore, the second torsion arm 203 of the spring hook 2 extends horizontally towards the center of the opening 3, with a bent portion 204 located at the end of the second torsion arm 203 away from the torsion spring body 201. By increasing the lever arm of the second torsion arm 203, the user can more easily pry the second torsion arm 203 open during installation.

[0032] In this embodiment, the frame body 1 is rectangular, with an opening 3 in the center for installing the mesh 6. The frame body 1 includes four prongs 101 located at the four corners, with frame profiles 102 connected to both ends of each prong 101. The prongs 101 and the frame profiles 102 together form a square. The frame profiles 102 have snap-fit ​​grooves 8 along their length, and the mesh is fixed in place by pressing a strip into the snap-fit ​​grooves 8.

[0033] The pins 101 are right-angled, with both ends inserted into the frame profiles 102 and fixed by friction. The portion of the pins 101 inserted into the frame profiles 102 has an interference fit with the frame profiles 102, and can be engaged by applying external force. When assembling the hanging frame body 1, the frame profiles 102 between the two upper pins 101 can be installed first, then the frame profiles 102 between the two lower pins 101 can be installed, and finally, they can be inserted into the two vertical frame profiles 102 to complete the overall installation.

[0034] The torsion spring body 201 is specifically located at the part where the pin 101 passes through the frame profile 102. The torsion spring body 201 is first placed on the pin 101 and then the pin 101 is inserted into the frame profile 102. The pin 101 and the frame profile 102 cover the torsion spring body 201 to achieve horizontal limitation. The first torsion arm 202 and the second torsion arm 203 respectively abut against each other to prevent the torsion spring body 201 from moving horizontally.

[0035] A limiting groove 4 is formed on the upper edge of the pin 101 in the horizontal direction. The first torsion arm 202 passes into the limiting groove 4 to limit the torsion spring body 201 in the vertical direction. There is a notch 5 between the pin 101 and the frame profile 102 for the second torsion arm 203 to pass through. After the pin 101 and the frame profile 102 are installed, the first torsion arm 202 is located inside the hanging frame body 1, and the second torsion arm 203 is located outside the hanging frame body 1.

[0036] The installation process of this utility model is as follows:

[0037] like Figure 5 As shown, the second torsion arm 203 of the spring hook 2 above (or below) the frame body 1 is pried outward, and the frame body 1 is inserted at an angle upward (or downward) so that the bent part 204 of the spring hook 2 abuts against the edge of the window 7. Then, the frame body 1 is rotated toward the window 7, and the second torsion arm 203 of the lower spring hook 2 is pried outward. At this time, in order to prevent the bent part 204 from being stuck by the window 7, the second torsion arm 203 can be slightly raised and deformed. After the bent part 204 abuts against the edge of the window 7, the screen window is installed. The screen window is limited vertically, but can move horizontally.

[0038] This embodiment also provides a screen window, such as Figure 6 As shown, the mounting frame described above is included, and the opening 3 of the frame body 1 is covered with a mesh 6.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
