Abstract
Description
Technical Field
[0001] This application relates to the field of furniture technology, and more particularly to an anti-pinch door frame with a handle mechanism. Background Technology
[0002] In modern home life, door frames are an important part of home facilities, and their safety is of paramount importance. Currently, when traditional door frames are closed, the gap between the door frame and the door can easily cause users' hands to be pinched, especially when there are children or elderly people with mobility difficulties in the home, this safety hazard is even more prominent.
[0003] Existing anti-pinch door frames mostly use cushioning materials such as rubber strips to reduce the risk of pinching injuries. However, when the door frame is closed, the gap between the frames will continuously decrease and the thickness of the rubber strips is limited, so the user's hand may still be pinched. At the same time, existing door handles are usually located near the edge of the door frame and the gap is small. When the user is closing the door, their hand is likely to be close to the gap area when they are gripping the handle, which increases the probability of being pinched.
[0004] Based on the above reasons, this utility model proposes an anti-pinch home door frame with a handle mechanism, which has multiple anti-pinch functional advantages and can meet the growing demand for home safety. Utility Model Content
[0005] In view of the above problems, this application provides an anti-pinch home door frame with a handle mechanism to solve the problem of easy hand pinching in existing home door frames.
[0006] This application provides an anti-pinch door frame with a handle mechanism, including a door frame body. The door frame body is rectangular and has a groove on its inner side wall. A plurality of threaded holes are opened on one of the vertical sides of the door frame body and a movable plate is fitted thereon. A plurality of countersunk holes are opened on the side wall of the movable plate. A connecting bolt is inserted into the countersunk hole. The connecting bolt is threadedly connected to the threaded hole and a spring is fitted on the outer side wall. A handle plate is fixedly connected to the center of the front side wall of the movable plate.
[0007] In some embodiments, the handle plate has an L-shaped cross-section, and the horizontal edge of the handle plate is oriented towards the center of the door frame body.
[0008] In some embodiments, the movable plate has a concave cross-section, and the internal width of the movable plate is the same as the thickness of the door frame body.
[0009] In some embodiments, the movable plate is fixedly connected to the sidewalls on both sides of the countersunk hole with leather pads.
[0010] In some embodiments, a baffle is inserted into the countersunk hole, and the baffle is circular.
[0011] With the above solution, when closing the two door frame bodies, if the operator's hand is located between the two door frame bodies, the movable plate can move as the door frame bodies close together. The movable plate compresses and deforms the spring, reducing the direct impact on the hand, thus providing the user with reaction time to pull their hand out and reducing pinching injuries. The effect is good. By installing the handle plate in the center of the movable plate with the opening facing the center of the door frame body, when closing the two door frame bodies using the handle plate, on the one hand, the two hands can be placed on both sides to avoid pinching injuries to the hand. On the other hand, the large gap between the two handle plates further reduces the possibility of pinching injuries to the hand and improves the anti-pinch effect.
[0012] The above description is merely an overview of the technical solutions of the embodiments of this application. In order to better understand the technical means of the embodiments of this application and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of this application more obvious and understandable, specific implementation methods of this application are described below.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] The terms "comprising" and "having," and any variations thereof, in the specification, claims, and drawings of this application are intended to cover without excluding other meanings. The words "a" or "an" do not exclude the presence of multiples. Unless otherwise stated, "multiple" means two or more (including two), and similarly, "multiple sets" means two or more (including two sets).
[0023] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application. For example, in the description of this application, terms such as "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0024] Furthermore, descriptions of directions used to explain the operation and construction of the components in this embodiment, such as height, are not absolute but relative. Although these directions are appropriate when the components are in the positions shown in the figure, they should be interpreted differently when these positions change to correspond to the changes.
[0025] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, "connection" or "linkage" in mechanical structures can refer to a physical connection, such as a fixed connection, a detachable connection, or an integral connection.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0026] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0027] like Figure 1-5 As shown, this application embodiment provides an anti-pinch home door frame with a handle mechanism, including a door frame body 1. The door frame body 1 is rectangular and has a groove 2 on its inner side wall. A plurality of threaded holes 3 are opened on one of the vertical sides of the door frame body 1 and a movable plate 4 is fitted on it. A plurality of countersunk holes 5 are opened on the side wall of the movable plate 4. A connecting bolt 6 is inserted into the countersunk hole 5. The connecting bolt 6 is threadedly connected to the threaded hole 3 and a spring 7 is fitted on the outer side wall.
[0028] In the technical solution of this embodiment, during use, the connecting bolt 6 can be rotated according to the relative position of the two door frame bodies 1 to change the position of the movable plate 4 on the door frame body 1, thereby ensuring the installation effect between the door frame bodies 1. When the two door frame bodies 1 are closed, if the operator's hand is between the two door frame bodies 1, the movable plate 4 can move as the door frame bodies 1 are closed. The movable plate 4 compresses and deforms the spring 7, reducing the direct impact on the hand, thereby providing reaction time for the user to pull out their hand and reducing pinching injury, resulting in good performance.
[0029] Furthermore, the movable plate 4 has a concave cross-section, and the internal width of the movable plate 4 is the same as the thickness of the door frame body 1, which can make the movable plate 4 fit tightly with the door frame body 1, reducing the possibility of the movable plate 4 pinching the user.
[0030] Furthermore, leather pads 9 are fixedly connected to the side walls of the movable plate 4 on both sides of the countersunk hole 5. The leather pads 9 not only effectively improve the anti-pinch effect, but also improve the sealing of the two door frames after they are closed, making them easier to use.
[0031] Furthermore, a baffle 10 is inserted into the countersunk hole 5. The baffle 10 is circular and can close the countersunk hole 5, reducing misoperation of the connecting bolt 6 and improving the overall aesthetics.
[0032] A handle plate 8 is fixedly connected to the center of the front side wall of the movable plate 4. The handle plate 8 has an L-shaped cross section, and the horizontal side of the handle plate 8 is set towards the center of the door frame body 1.
[0033] In the technical solution of this embodiment, by installing the handle plate 8 at the center of the movable plate 4 with the opening facing the center of the door frame body 1, when the two door frame bodies 1 are closed by the handle plate 8, on the one hand, the two hands can be placed on the sides respectively to avoid pinching the hands, and on the other hand, the large gap between the two handle plates 8 further reduces the possibility of pinching the hands and improves the anti-pinch effect.
[0034] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this application and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.
[0035] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
