Technical Field

[0001] The invention belongs to the field of door and window transmission box installation structures, and in particular relates to a door and window transmission box and a door and window having the door and window transmission box. Background Art

[0002] The transmission box is one of the important hardware accessories for opening and closing doors and windows. Conventional transmission boxes generally need to be fixed on the profiles of doors and windows by fixing methods. The commonly used fixing methods of existing transmission boxes are fixing with self-tapping screws and clamping with nut blocks. With the self-tapping screw method, it is necessary to use an electric screwdriver to drive the screws into the wall of the door and window profile for fixing. This fixing method will leave a fixing hole in the profile wall. If there is a mistake during installation and the fixing hole needs to be disassembled, the fixing hole is easy to expand when it is fixed again after disassembly, which will weaken the fixing strength. The installed transmission box is easy to loosen, and the reliability is poor. Summary of the invention

[0003] The object of the present invention is to overcome at least one of the above-mentioned deficiencies of the prior art, and to provide a door and window transmission box and a door and window having the door and window transmission box.

In this embodiment, the quick-installation structure 200 is provided at both ends of the transmission box body 100, and the transmission box body 100 (including the quick-installation structure 200) can be obliquely inserted into the installation cavity 910 (such as Figure 2 As shown), at this time, the slider member 210 is close to the transmission box body 100, so that the transmission box body 100 (including the quick-install structure 200) is easy to insert into the installation cavity 910. In a specific application, one end of the transmission box body 100 can be inserted into one end of the installation cavity 910 first, and then the one end of the transmission box body 100 is placed downward in the installation cavity 910, that is, the slider member 210 is relatively far away from the inner top wall of the installation cavity 910. After the transmission box body 100 is placed in the installation cavity 910, the screw rod 220 can be rotated to make the slider member 210 upward (close to the inner top wall of the installation cavity 910) under the action of the screw rod 220, so that the slider member 210 can be pressed against the inner top wall 901 of the installation cavity 910 (as shown in FIG. Figure 5 and Figure 6As shown), the bottom of the transmission box body 100 is pressed against the bottom of the installation cavity 910 of the profile 900, so that the transmission box body 100 is reliably fixed, and there will be no looseness even if it is disassembled and assembled many times, and the installation reliability of the transmission box body 100 is good.

[0025] In specific applications, the quick-install structure 200 may be provided at only one end of the transmission box body 100 , and a hook structure, an abutment structure, etc. may be provided at the other end, which also falls within the protection scope of the present invention.

[0026] Specifically, the end of the transmission box body 100 is provided with an axial hole 102, and the bottom of the screw rod 220 is movably inserted into the axial hole 102.

[0030] Specifically, a limiting sleeve or a limiting hole is provided below the limiting baffle 170, and the top of the screw rod 220 extends into the limiting sleeve or the limiting hole. The screw rod 220 can rotate in situ and can reliably lift and lower the slider member 210.

[0031] Specifically, a tool action hole is provided at the top of the screw rod 220, and the through hole 171 is larger than the tool action hole and smaller than the diameter of the limiting sleeve 172 or the limiting hole. The tool action hole can be a hexagonal hole, a slot, a cross slot, etc.

[0032] Specifically, the slider member 210 is in a rectangular plate or block shape, etc. The slider member 210 can be rectangular, its width can be smaller than the width of the opening of the installation cavity 910, and its length can be greater than the width of the opening of the installation cavity 910. After the slider member 210 is placed in the opening of the installation cavity 910, at least two sides of the slider member 210 are in contact with the transmission box body 100 or related structural parts. When the screw 220 is rotated, the slider member 210 can slide up and down but cannot rotate. In specific applications, the slider member 210 is a metal part or a hard plastic part.

[0033] Specifically, the upper surface of the slider member 210 is provided with anti-skid convex patterns or a rubber layer to improve reliability.

[0034] Specifically, the transmission box body 100 includes an upper box 130 and a lower box 140 that are matched, and a driving gear 150 and a transmission member 160 are disposed in the upper box 130 and the lower box 140.
