[0039] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0040] Combination Figure 1 and Figure 2The utility model provides a wind bracing structure 10, including: a sliding tube 11 and a sliding rod 12, a cavity 111 is axially arranged inside the sliding tube 11, one end of the sliding tube 11 has an opening 112 connected to the cavity 111, the wind bracing structure 10 also includes a head 13, the head 13 includes: a head body 131, the head body 131 is arranged in the opening 112, the head body 131 has a through hole 1311 passing through, one end of the sliding rod 12 passes through the through hole 1311 and is inserted into the cavity 111 and can slide axially in the cavity 111; at least one collision block 132, the collision block 132 is arranged on the side wall of the head body 131; wherein the collision block 132 is connected to the sliding tube 11 to fix the head body 131 to the opening 112, and the head body 131 is made of plastic material, and the collision block 132 is made of metal material. In this embodiment, the end cap 13 is set to be a split type, wherein the end cap body 131 is made of plastic material, which has good shock absorption performance and can reduce the noise generated during the sliding process of the slide rod 12 in the slide tube 11, thereby improving the user experience; the collision block 132 is made of metal material, which has good stability and durability and can maintain its performance unchanged during long-term use. Therefore, the end cap 13 composed of the end cap body 131 and the collision block 132 is set at the opening 112 of the slide tube 11, which can not only ensure the stability of the installation with the slide tube 11, but also ensure that the noise generated when the slide rod 12 slides, making up for the defects of the one-piece end cap in the prior art that the strength is low when the plastic material is used and the slide rod 12 slides noisy when the metal material is used.

[0041] Further, such as Figure 3 As shown, at least one notch 1321 is provided on the collision block 132, and at least one protrusion 113 is provided on the inner wall of the sliding tube 11, and the protrusion 113 is engaged in the notch 1321 to limit the axial movement of the collision block 132 relative to the sliding tube 11. Specifically, the notch 1321 on the collision block 132 is engaged with the protrusion 113 on the inner wall of the sliding tube 11, so that the collision block 132 and the sliding tube 11 are relatively fixed, and the connection between the collision block 132 and the head body 131 makes the head body 131 and the sliding tube 11 relatively fixed, so that the head 13 and the sliding tube 11 are fixed. It can be understood that the head 13 in this embodiment is connected to the sliding tube 11 through the collision block 132, and the collision block 132 made of metal is engaged with the sliding tube 11, which ensures the stability of the connection structure between the head 13 and the sliding tube 11.

[0042] Further, the notch 1321 includes a first notch 13211 and / or a second notch 13212; wherein the first notch 13211 includes a first blocking portion 132111 away from the opening 112 and a first inclined portion 132112 close to the opening 112, the protrusion 113 includes a second blocking portion 1131 away from the opening 112 and a second inclined portion 1132 close to the opening 112, the second blocking portion 1131 blocks the first blocking portion 132111 from sliding out of the opening 112 in the axial direction, and the first inclined portion 132112 and the second inclined portion 1132 are arranged in coordination. The first blocking portion 132111 and the first inclined portion 132112 may be directly connected, or a connecting portion 132113 may be arranged between the first blocking portion 132111 and the first inclined portion 132112, and the connecting portion 132113 is connected between the bottom of the first blocking portion 132111 and the bottom of the first inclined portion 132112. The first blocking portion 132111 and the first inclined portion 132112 are both disposed on the surface of the collision block 132 and are disposed toward the inner side of the collision block 132 , that is, the two together constitute a groove structure formed on the surface of the collision block 132 .

[0043] Optional, combined Figures 3 to 6 When assembling the collision block 132 to the slide tube 11, only the first notch 13211 and the protrusion 113 can be used for clamping and fixing, or only the second notch 13212 and the protrusion 113 can be used, or both the first notch 13211 and the second notch 13212 and the corresponding protrusion 113 can be used for clamping and fixing to fix the head 13 to the opening 112 of the slide tube 11. The first notch 13211 is provided at the side edge (for example, the upper edge and / or the lower edge) of the collision block 132, and the second notch 13212 is a limiting hole provided in the middle of the collision block 132. Preferably, the collision block 132 is provided with both the first notch 13211 and the second notch 13212, and the first notch 13211 and the second notch 13212 make the connection between the collision block 132 and the inner wall of the slide tube 11 more stable.

[0044] Specifically, the matching arrangement of the first inclined portion 132112 and the second inclined portion 1132 reduces the resistance during installation. When the protrusion 113 is engaged in the first notch 13211, the second blocking portion 1131 can effectively block the first blocking portion 132111 from sliding out of the opening 112 in the axial direction, thereby ensuring the stable position of the collision block 132 in the slide tube 11. The second notch 13212 is a limiting hole provided on the collision block 132, which blocks the second blocking portion 1131 to limit the collision block 132 from sliding out of the opening 112 in the axial direction. The second notch 13212 is used to limit the movement of the collision block 132 in the axial direction. The second blocking portion 1131 of the protrusion 113 also plays a blocking role to prevent the collision block 132 from sliding out of the opening 112 in the axial direction.

[0045] It should be explained that the first blocking portion 132111 can be a vertically arranged straight edge, and the second blocking portion 1131 can be a vertically arranged straight edge. When the first blocking portion 132111 slides out relative to the second blocking portion 1131, it will be blocked by the second blocking portion 1131, thereby preventing the collision block 132 from sliding out of the opening 112 in the axial direction. The first inclined portion 132112 can be an inclined wall surface, the bottom of which is close to the bottom of the first blocking portion 132111 (if the connecting portion 132113 is not provided, the bottom of the inclined wall surface is directly connected to the bottom of the first blocking portion 132111; if the connecting portion 132113 is provided, the bottom of the inclined wall surface is connected to the connecting portion 132113), and the inclined wall surface is inclined from the bottom to the top in a direction away from the first blocking portion 132111. The second inclined portion 1132 is an inclined wall surface adapted to the first inclined portion 132112, and its structure is similar to that of the first inclined portion 132112, so it is not repeated.

[0046] Furthermore, a plurality of notches 1321 are provided, and a plurality of protrusions 113 are provided correspondingly, the notches 1321 are provided in different directions of the collision block 132, and the protrusions 113 are distributed on the inner wall of the slide tube 11 in different directions. In this embodiment, through the matching design of multiple notches 1321 and multiple protrusions 113, the collision block 132 and the slide tube 11 can achieve more stable connection and limit in multiple directions.

[0047] Further, such as Figure 7 and Figure 8 As shown, the arrangement of the collision block 132 prevents the head 13 from sliding out of the opening 112 in the axial direction. Furthermore, in order to prevent the head 13 from sliding into the slide tube 11 in the axial direction, one end of the head body 131 in this embodiment extends into the opening 112, and the other end is provided with a blocking portion 1312, which is located outside the opening 112. The size of the blocking portion 1312 in at least one direction is larger than the size of the opening 112 in the corresponding direction, and is used to limit the head body 131 from sliding into the opening 112. At the same time, the blocking portion 1312 preferably closes the gap between the slide rod 12 and the slide tube 11, effectively preventing external dust, debris, etc. from entering the interior of the slide tube 11.

[0048] Specifically, Fig. 9 As shown, a mounting groove 1313 is provided on the side between the two ends of the end cap body 131, and the collision block 132 is located in the mounting groove 1313 to limit the axial movement of the collision block 132 relative to the end cap body 131. Therefore, when the end cap body 131 is to move into the slide tube 11 along the axial direction, the collision block 132 will abut against the groove wall of the mounting groove 1313 to limit the movement of the end cap body 131, thereby ensuring that the end cap 13 as a whole is relatively fixed to the slide tube 11.

[0049] Furthermore, in order to improve the stability and installation accuracy of the head 13, a positioning portion 13131 is provided at one end of the installation groove 1313 close to the opening 112, and a positioning groove 1322 is provided at one end of the collision block 132 close to the opening 112. The positioning portion 13131 is located in the positioning groove 1322. The design of the positioning groove 1322 and the positioning portion 13131 ensures the correct position of the collision block 132 during the installation process and increases the contact area between the head body 131 and the collision block 132.

[0050] Further, the two opposite sides between the two ends of the end cap body 131 are provided with mounting grooves 1313, and two collision blocks 132 are provided, which are respectively located in the two mounting grooves 1313. Specifically, the two opposite sides between the two ends of the end cap body 131 close to the opening 112 and away from the opening 112 are provided with mounting grooves 1313, and the two collision blocks 132 are respectively installed in the two mounting grooves 1313. In another embodiment, the end cap body 131 is a symmetrical structure, and the two sides thereof are respectively provided with mounting grooves 1313.

[0051] Optional, such as Fig.10 As shown, the wind bracing structure 10 of this embodiment further includes a fixing member 14, a friction member 15 and a force-bearing component 16, which are sequentially arranged at one end of the slide bar 12, and the force-bearing component 16 can collide with one end of the head body 131 as the slide bar 12 slides. In this embodiment, the force-bearing component 16 is used to buffer the pressure applied by the friction member 15 to one end of the head body 131, and the friction member 15 is used to provide resistance to the sliding of the slide bar 12.

[0052] like Fig.11 and Fig.12 As shown, the utility model also provides a door and window 20, including a sash profile 21 and a frame profile 22, and also includes the above wind bracing structure 10, the other end of the sliding tube 11 is connected to the sash profile 21, and the other end of the sliding rod 12 is fixed to the frame profile 22.

[0053] In a specific embodiment, the following are specific steps for installing the wind bracing structure 10 to the door and window 20. First, the fixing head 30 and the fixing block 40 are put into the slide tube 11. The slide tube 11 is provided with a fixing hole 50. The base 60 and the plastic gasket 70 are placed on the slide tube 11 in sequence, aligned with the fixing hole 50 of the slide tube 11, and then the first positioning shaft 80 is inserted for riveting and fixing. Then, a positioning protrusion is set from the side of the slide tube 11, and a groove matching the positioning protrusion is set on the fixing block 40 to fix the fixing block 40. Then, the base 60 is placed in the fan groove of the fan profile 21 and slid to a suitable position for fixing. The fixing method can be screw fixing, so that the other end of the slide tube 11 is fixed to the fan profile 21.

[0054] A first through hole is set at the other end of the sliding rod 12, and the second positioning shaft 90 can be inserted into the first through hole. At the same time, a second through hole cooperating with the second positioning shaft 90 is set on the fixing plate 100, and a third through hole cooperating with the second positioning shaft 90 is set on the upper fixing block 110. The second positioning shaft 90 is connected to the first through hole, the second through hole and the third through hole in sequence. The axial hole of the fixing plate 100 and the axial hole of the upper fixing block 110 are matched to the other end of the sliding rod 12 and fixed by riveting with a connecting piece 120. The connecting piece 120 can be a screw, and finally locked on the frame profile 22.

[0055] It should be explained that one side of the fan profile 21 is rotatably connected to the frame profile 22, and the other side is slidably connected to the slide tube 11; one end of the slide tube 11 is slidably connected to the slide rod 12, and the other end is slidably connected to the fan profile 21; one end of the slide rod 12 is slidably connected to the slide tube 11, and the other end is rotatably connected to the frame profile 22. When the fan profile 21 and the frame profile 22 rotate relative to each other, the slide rod 12 will slide axially in the cavity 111 of the slide tube 11. Specifically, when the angle between the fan profile 21 and the frame profile 22 becomes larger, the slide rod 12 slides toward the opening 112 of the slide tube 11, close to the other end of the slide tube 11; when the angle between the fan profile 21 and the frame profile 22 becomes smaller, the slide rod 12 slides toward the opening 112 of the slide tube 11, close to the other end of the slide rod 12.
