[0020] Figure 2 It is a structural diagram of the door frame structure in the present invention.

[0021] Figure 3 It is a structural schematic diagram of the door frame in the present utility model. DETAILED DESCRIPTION Example

[0022] like Figure 1 As shown, the utility model describes a closing strip used on a door frame, comprising an integrally formed wide strip 1, a narrow strip 2, and a connecting strip 3, wherein the two ends of the wide strip 1 in the width direction respectively constitute a fixing piece 11 and a clamping piece 12, the narrow strip 2 and the clamping piece 12 are arranged side by side, and the side of the clamping piece 12 away from the fixing piece 11 is connected to one side of the connecting strip 3, and the narrow strip 2 is also connected to the other side of the connecting strip 3, and an embedding groove 4 is formed between the clamping piece 12 and the narrow strip 2.

[0023] The closing strip adopts an integrally formed wide strip 1, narrow strip 2 and connecting strip 3, which can make the closing strip have a very simple and reliable structure, thereby ensuring that the closing strip has a very high reliability.

[0024] By forming a fixing piece 11 and a clamping piece 12 at each end of the wide strip 1 in the width direction, arranging the narrow strip 2 and the clamping piece 12 side by side, and making the side of the clamping piece 12 away from the fixing piece 11 connect to one side of the connecting strip 3, and making the narrow strip 2 connect to the other side of the connecting strip 3, and forming an inserting groove 4 between the clamping piece 12 and the narrow strip 2, this not only ensures a very simple overall structure of the closing strip, but also provides an independent fixing piece 11 that is not interfered with by the narrow strip 2, thereby facilitating installation and fixation. This closing strip can help reduce user costs and improve installation and positioning efficiency.

[0025] Furthermore, the embedding groove 4 thus constructed can be beneficial for providing extremely stable and reliable positioning for the door cover, thereby being beneficial for improving the stability and reliability of the door cover assembly.

[0026] At the same time, this kind of closing strip can be easily installed through an embedded positioning method during installation. Such a closing strip can help to achieve a very stable and reliable closing positioning effect, and it can have very high reliability and applicability.

[0027] like Figure 1 As shown, the fixing piece 11 is provided with a countersunk groove 111 on the surface thereof near the embedding groove 4. When the fixing piece 11 is fixed to the wall hole with a screw, the countersunk groove 111 can be used to hide the nut end of the screw, thereby preventing the screw from occupying the installation space of the door frame. This not only prevents the screw from affecting the installation and positioning stability of the door frame, but also eliminates the need for a relief groove on the door frame, thereby preventing the structural strength of the door frame from being weakened, thereby further improving the reliability and applicability of the closing strip.

[0028] like Figure 1 As shown, the wide strip 1 is a hollow strip, which can make the wide strip 1 have high structural strength and stability, thereby being conducive to improving the stability and reliability of installation and positioning.

[0029] like Figure 1 As shown, both the fixing piece 11 and the clamping piece 12 are hollow pieces, and the countersunk groove 111 is formed by the outer wall of the fixing piece 11 being recessed inward. This not only provides high structural strength at the screw locking point, but also allows the fixing piece 11 to have a certain elastic contraction effect when the screw is locked, which can play a certain elastic tightening role on the screw, thereby helping to improve the reliability of installation and positioning.

[0030] like Figure 1 As shown, the countersunk groove 111 is a strip-shaped countersunk groove extending along the length of the fixing plate 11; a first positioning groove 112 extending along its length is provided in the middle of the bottom of the countersunk groove 111. This not only facilitates the molding and manufacturing of the countersunk groove 111 and the first positioning groove 112, but also provides accurate identification positions for the opening of multiple screw holes through the first positioning groove 112, thereby facilitating subsequent accurate and stable installation and positioning.

[0031] like Figure 1 As shown, the connecting strip 3 has a second positioning groove 31 extending along its length in the middle portion of its surface facing the mounting groove 4. When the closing strip is to be fixed to the door frame with screws, the second positioning groove 31 provides an accurate mark for the opening of the relevant screw holes, thereby facilitating accurate and stable assembly of the connecting strip 3 to the door frame.

[0032] like Figure 1 As shown, a groove 32 extending along its length is formed in the middle portion of the surface of the connecting strip 3 facing the embedding groove 4, and the second positioning groove 31 is located at the bottom of the groove 32. The groove 32 provides a certain storage space for the nut end of the screw, thereby preventing the screws securing the connecting strip 3 from occupying too much space in the embedding groove 4, thereby ensuring sufficient embedding space for the door frame, which helps to improve the stability and reliability of subsequent assembly.

[0033] like Figure 1 As shown, the narrow strip 2 has a ridge 21 on its surface facing the mounting groove 4. The ridge 21 is located on the side of the narrow strip 2 facing away from the connecting strip 3. A guide slope 211 is formed on the side of the ridge 2 facing away from the connecting strip 3, sloping into the mounting groove 4. The surface of the ridge 21 facing the wide strip 1 is a contact flat surface 212. The ridge 21 enhances the structural strength of the narrow strip 2, thereby improving the reliability of the closing strip. Positioning the ridge 21 on the side of the narrow strip 2 facing away from the connecting strip 3 allows the ridge 21 to better perform its reinforcing function. The guide slope 211 serves as a guide when inserting the door frame, thereby facilitating installation. It also provides storage space for putty or decorative paint when applied to the outer wall of the door frame, ensuring that the end of the putty or decorative paint is more stably attached to the closing strip, thereby improving the closing quality. The abutment plane 212 not only provides a contact surface for the door frame but also ensures that the convex strip 21 has high reliability, thereby improving reliability and applicability. Example

[0034] like Figure 1 and Figure 2 As shown, a door frame structure described in the present invention includes the closing strip 10 and the door frame plate 20 described in the first embodiment, and the end of the door frame plate 20 is embedded in the embedding groove 4.

[0035] The overall structure of the door frame structure is very simple, which not only reduces the manufacturing and use costs, but also facilitates installation and positioning, thereby improving the installation and positioning efficiency.

[0036] like Figure 2 As shown, a putty layer 100 and / or a paint layer is provided on the outer wall of the door frame 20, so that a good closing effect can be achieved, thereby being beneficial to improving the decoration quality.

[0037] like Figure 2 and Figure 3 As shown, the door frame structure also includes a door frame 30. A positioning notch 302 is provided on the side of the wall-facing surface 301 of the door frame 30 for fitting the closing strip 10. The closing strip 10 is fitted into the positioning notch 302. This improves the accuracy and stability of the assembly of the closing strip 10 and the door frame 30, and creates a very good closing effect between the door frame 20 and the door frame 30, thereby improving the quality of the door frame structure.

[0038] like Figure 2 and Figure 3As shown, the positioning notch 302 is provided with a wavy surface 303 or a toothed surface on the mouth wall facing the connecting strip 3, so that when the connecting strip 3 is locked on the door frame 30 by screws (not shown in the figure), the positioning strength can be enhanced, thereby helping to further improve the reliability of the door frame structure.

[0039] The above embodiments are preferred embodiments of the present invention. All structures similar to those of the present invention and equivalent changes made thereto should fall within the scope of protection of the present invention.
