Description

Technical Field

[0001] The utility model relates to the technical field of door and window fixing pieces, in particular to an extendable door and window fixing piece. Background Art

[0002] During the installation process of doors and windows, the frames of the doors and windows, that is, the aluminum alloy profiles, need to be connected to the profiles with fixing plates, and then the fixing plates are installed against the wall, and finally screws are used to pass through the profiles and connect them to the wall. In this way, dual fixed installation of fixing plate connection and screw connection can be achieved.

[0003] According to a one-way fixing plate for door and window installation with publication number CN209817738U, the fixing plate comprises a fixing plate, the fixing plate is composed of a first fixing plate arranged in the center and two second fixing plates arranged symmetrically with respect to the first fixing plate, the first fixing plate is provided with a first mounting hole, and the two second fixing plates are provided with a second mounting hole. A plurality of gasket strips are bonded to the two second fixing plates by epoxy resin adhesive. The plurality of gasket strips are arranged at intervals on the second fixing plate.

[0004] With respect to the above-mentioned related schemes, the first fixing plate can fit perfectly with the U-shaped door and window groove on the outer edge of the aluminum alloy door and window frame. Then, the first fixing plate and the aluminum alloy door and window frame are installed together by passing bolts through the first mounting hole, and then the second fixing plates on both sides are installed on the wall through the second mounting hole with expansion bolts. In this way, the fixing plate can fit tightly and fix with the aluminum alloy door and window frame, which invisibly strengthens the connection strength between the aluminum alloy door and window frame and the wall, improves the compressive resistance of the aluminum alloy door and window frame when facing a large impact force, and is not easy to deform and damage. However, due to its fixed size, it can only be applied to aluminum alloy door and window frames of a single size, thereby limiting the scope of application of the door and window fixing plate. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an extensible door and window fixing plate to solve the technical problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an expandable door and window fixing plate, comprising a fixing plate body, wherein the fixing plate body is composed of a left support plate, a right support plate and a fixing hole, wherein the left support plate is slidably connected to one side of the right support plate, a support groove is provided at one end of the left support plate, and a support block is welded to the end of the right support plate close to the support groove.

[0007] Preferably, fixing holes are provided inside one side of the left supporting plate and the right supporting plate.

[0008] Preferably, two groups of fixing holes are symmetrically arranged about the center axis of the left support plate and the right support plate.

[0009] Preferably, the left support plate and the right support plate form a sliding structure through support grooves and support blocks.

[0010] Preferably, the support groove and the support block are both configured as rectangular structures.

[0011] Preferably, a positioning groove is formed at one end of the support block, and a screw extending into the positioning groove is threadedly connected to one end of the left support plate.

[0012] Preferably, the support block and the support slot form a snap-fit ​​structure via screws and positioning slots.

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] 1. The existing door and window fixing piece has a fixed size, so that it can only be applied to aluminum alloy door and window frames of a single size, thereby limiting the scope of application of the door and window fixing piece. The utility model is provided with a left support plate, a right support plate, a support block, a support groove, a positioning groove and screws. Since the left support plate and the right support plate are slidably connected through the support block and the support groove, the distance between the left support plate and the right support plate can be adjusted by pulling the left support plate, so that the door and window fixing piece has an extension function, so that it can be applied to aluminum alloy door and window frames of various sizes, thereby expanding its scope of application;

[0015] 2. The height of the existing door and window fixing plates is generally fixed, which makes the contact area between the door and window fixing plates and the aluminum alloy door and window frames and the wall small, resulting in poor strength of the door and window fixing plates. The utility model doubles the height of the door and window fixing plates and doubles the number of fixing holes, so that the contact area between the door and window fixing plates and the aluminum alloy door and window frames and the wall can be increased, thereby improving the strength of the door and window fixing plates and extending their service life.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0023] The following describes an embodiment of the utility model based on its overall structure.

[0024] An extendable door and window fixing sheet, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a fixing plate body 1, and the fixing plate body 1 is composed of a left support plate 101, a right support plate 102 and a fixing hole 103. The left support plate 101 is slidably connected to one side of the right support plate 102. A support groove 2 is opened at one end of the left support plate 101, and a support block 3 is welded to one end of the right support plate 102 close to the support groove 2. The left support plate 101 and the right support plate 102 form a sliding structure through the support groove 2 and the support block 3. The support groove 2 and the support block 3 are both set to a rectangular structure. The distance between the left support plate 101 and the right support plate 102 can be adjusted by pulling the left support plate 101, so that the fixing plate body 1 has an extension function, so that it can be suitable for aluminum alloy door and window frames of various sizes, thereby expanding its scope of application.

[0025] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 It can be seen that fixing holes 103 are provided inside one side of the left supporting plate 101 and the right supporting plate 102, and the fixing plate body 1 is connected to the wall through bolts and the fixing holes 103, thereby realizing the installation of the aluminum alloy door and window frame.

[0026] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 It can be seen that a positioning groove 5 is provided at one end of the support block 3, and one end of the left support plate 101 is threadedly connected with a screw 4 extending into the positioning groove 5. The support block 3 and the support groove 2 form a locking structure through the screw 4 and the positioning groove 5. By turning the knob screw 4, one end of the screw 4 is screwed into the positioning groove 5, thereby realizing the positioning of the left support plate 101 and the right support plate 102 after adjustment.

[0027] See also Figure 1, Figure 3 , Figure 4 and Figure 5 It can be seen that two groups of fixing holes 103 are symmetrically arranged about the central axis of the left support plate 101 and the right support plate 102. By doubling the height of the fixing plate main body 1 and doubling the number of fixing holes 103, the contact area between the fixing plate main body 1 and the aluminum alloy door and window frame and the wall can be increased, thereby improving the strength of the fixing plate main body 1 and extending its service life.
