It should be understood that the specific embodiments described herein are used only to illustrate the utility model and not to limit its scope.

[0021] As in the Fig. 1 and Fig. As shown in Figure 2, the utility model provides a clamping locking structure. The clamping locking structure comprises: a locking element 1 and a detent element 2. Specifically, the locking element 1 is provided with a groove 11. The groove 11 comprises: a slot opening 111 and a cavity 112.

[0022] In a specific embodiment, the locking element 1 is made of metal material. Preferably, the locking element 1 can be made of iron or aluminum profile, produced by processes such as tube bending or press bending and welding, and the groove 11 is formed by profile drawing.

[0023] The locking element 2 comprises: an insert strip 21 and a flexible clamping element 22 connected to the insert strip 21.

[0024] In one embodiment, as in the Fig. 1 and Fig. Figure 2 shows the insert strip 21 as having a long strip structure with a rounded rectangular cross-section. It should be noted that the cross-sectional shape of the insert strip 21 is not restricted by the utility model and users can define it as required.

[0025] In one specific embodiment, the insert strip 21 is made of a plastic material. Under external force, it can deform to a certain degree, allowing the insert strip 21 to be smoothly inserted into the slot opening 111 without being damaged. Simultaneously, the insert strip 21 is connected to the flexible clamping element 22. The use of plastic material ensures that when the flexible clamping element 22 is pulled, causing the insert strip 21 to rotate, the flexible clamping element 22 is not damaged, thus guaranteeing the safety and aesthetics of the clamping locking structure.

[0026] In one embodiment, the flexible tensioning element 22 comprises flexible fabric, such as Teslin, mesh fabric, plastic sheeting, etc. The flexible tensioning element 22 can also be replaced by steel wire, rope, or other materials with a certain degree of softness, with one end wrapped around the insert strip 21.

[0027] In this embodiment, the clamping locking structure is used to connect the locking element 1 and the detent element 2. The specific method comprises: inserting the insertion surface 212 into the slot opening 111 to allow the insert strip 21 to detent into the cavity 112, and pulling on the flexible clamping element 22, which causes the insert strip 21 to rotate within the cavity 112, thereby causing the locking surface 211 to bear against and be positioned on the inside of the slot opening 111, thus connecting the detent element 2 to the locking element 1.

[0028] In a preferred embodiment, the slot opening 111 is provided with a projection 113 that is oriented towards the interior of the cavity 112. After the insert strip 21 has been clicked into the cavity 112, the projection 113 can further restrict the ejection of the insert strip 21 and thus ensure the stability of the clamping locking structure.

[0029] Furthermore, the cavity 112 has a smooth arc shape, which ensures that the insert strip 21 rotates smoothly and without obstruction within the cavity 112, enabling a quick connection and locking of the locking element 1 and the latching element 2.

[0030] As in Fig. As shown in Figure 3, the utility model provides a door / window frame. The door / window frame comprises: a main frame 3 and a door / window trim 4. The main frame 3 and the associated door / window trim 4 are shown in Fig. 4 shown.

As shown in Fig. As shown in Figure 5, the locking element 1 is provided with a groove 11, and the groove 11 comprises a slot opening 111 and a cavity 112. In one embodiment, the slot opening 111 of the groove 11 is provided with a projection 113 which is oriented towards the interior of the cavity 112.

[0031] The door / window trim 4 comprises: the latching element 2 from the tension locking structure provided in the above embodiments. The latching element 2 is adapted to the locking element 1 of the main frame 3 in order to connect with the locking element 1 and thus form the tension locking structure, thereby connecting the main frame 3 and the door / window trim 4.

[0032] As in Fig. As shown in Figure 5, the locking element 2 comprises an insert strip 21 that fits into the slot opening 111 and a flexible clamping element 22 that is connected to the insert strip 21. Specifically, the insert strip 21 comprises a locking surface 211 that is larger than the slot opening 111 and an insertion surface 212 that is adapted to the slot opening 111; the flexible clamping element 22 is connected to the door / window trim 4. In a preferred embodiment, the flexible clamping element 22 is formed integrally with the door / window trim 4.

[0033] In this embodiment, the method for connecting the main frame 3 and the door / window panel 4 via the locking element 1 and the latching element 2 comprises: inserting the insertion surface 212 into the slot opening 111 to allow the insert strip 21 to latch into the cavity 112, and pulling on the door / window panel 4 via the flexible clamping element 22, which causes the insert strip 21 to rotate within the cavity 112, thereby positioning the locking surface 211 against the inside of the slot opening 111 and within it, thus connecting the door / window panel 4 to the main frame 3. In one embodiment, the projection 113 provided at the slot opening 111 further restricts the ejection of the insert strip 21 after it has latched into the cavity 112.

[0034] In one embodiment, the main frame 3 is provided with several locking elements 1, and the door / window trim 4 is provided with several latching elements 2 adapted to each locking element 1; preferably, the main frame 3 has a rectangular structure with a locking element 1 provided on each of its four sides; correspondingly, the door / window trim 4 also has a matching rectangular structure with latching elements 2 provided on its four sides, adapted to each locking element 1; thus, the connection of the main frame 3 and the door / window trim 4 by several of these tension locking structures can further secure the main frame 3 and the door / window trim 4, ensure the stability and security of the door / window frame, and also prevent damage to the door / window trim 4, thus ensuring the aesthetics of the door / window frame.

[0035] In one embodiment, the locking element 1 is made of iron profile or aluminum profile, produced by processes such as tube bending or press bending and welding to meet the product shape requirements, and the groove 11 is formed by profile drawing or bending processes.

[0036] In one embodiment, the insert strip 21 is made of a plastic material, including but not limited to: rubber, plastic or some composite materials.

[0037] In one embodiment, the door / window trim 4 and the flexible tensioning element 22 consist of flexible fabric, including but not limited to: Teslin, mesh fabric, plastic tarpaulin, etc.

[0038] In one embodiment as in Fig. As shown in Figure 7, it further comprises an elastomer 5, which is arranged within the cavity 112 and abuts the rear side of the locking element 2. The elastomer 5 prevents the locking element 2 from springing back, thus making its use more reliable. The elastomer 5 includes, but is not limited to: springs, elastic sheets, etc.

[0039] The utility model uses the tension locking structure to attach the door / window trim 4 to the main frame 3 without causing damage. This non-destructive fastening method places lower strength requirements on the door / window trim 4, allowing it to utilize a wider variety of flexible materials. It should be noted that the utility model does not restrict the materials and manufacturing processes of any structure; users can specify these as needed. Furthermore, the utility model does not limit the tension locking structure to connecting the main frame 3 and the door / window trim 4 within door / window frames. Users can still apply the tension locking structure to other connection and fastening scenarios between any frame structure and flexible fabric, as required.

[0040] To better illustrate and describe a door / window frame that uses multiple tension locking structures, the utility model provides a specific embodiment.

[0041] Design 1: A door / window frame suitable for tents.

[0042] As in Fig. Figure 6 shows a structural schematic diagram of a tent in one embodiment of the utility model. The tent comprises several door / window frames. Each door / window frame comprises a main frame and a door / window trim.

[0043] The main frame is a rectangular frame made of iron or aluminum profile. The main frame includes four locking elements, one on each of the four sides. Each locking element has a groove formed by profile drawing.

[0044] The door / window trim is a rectangular structure made of flexible fabric. It comprises four locking elements. This means that the four edge sections of the door / window trim act as four flexible tensioning elements, with plastic insert strips wrapped around the edges.

[0045] The method for joining the main frame and the door / window trim involves: sequentially inserting the four insert strips into the corresponding grooves of the main frame, and pulling on the edges of the door / window trim (i.e., the flexible tensioning elements), which causes each insert strip to rotate within the cavity of its corresponding groove and snap into place. Once the main frame and door / window trim are joined, the trim is in a taut state, allowing any patterns or designs on the trim to be fully displayed.

[0046] In summary, the utility model provides a tension locking structure. This is achieved by arranging a groove with a slot opening and a cavity on a locking element and by arranging an insert strip wrapped with a flexible tensioning element on a latching element; by inserting the insert strip into the slot opening to allow it to snap into the cavity, and by pulling on the flexible tensioning element, which causes the insert strip to rotate within the cavity, thereby bearing against and positioning the insert strip against the slot opening, thus connecting the latching element to the locking element without damaging the surface of the latching element, and by supporting latching elements made of various materials; the utility model provides a door and window frame.By arranging several locking elements on a main frame and several latching elements adapted to each locking element on a door / window panel, the main frame and the door / window panel are connected by several of these tension locking structures without damaging the door / window panel; the utility model provides a tension locking structure and a door and window frame that solves the technical problem that existing fastening methods for door / window panels easily damage them and place high demands on the panel's strength.

[0047] Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utility.

[0048] The above embodiments merely illustrate the principles and effects of the utility model and are not intended to limit it. Any person with expertise in this field may modify or alter the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or alterations made by persons with general technical knowledge, without departing from the spirit and technical concepts disclosed by the utility model, remain subject to the claims of the utility model.
