Description

Technical Field

[0001] This utility model relates to the field of door and window components, specifically to a door and window transmission device. Background Technology

[0002] A door and window actuator is a device that achieves multi-point locking of doors and windows by rotating a handle. During installation, a through hole is drilled in the actuator's housing, and bolts are used to secure the actuator to the frame. However, a common problem with this installation method is that the actuator is prone to tilting after installation. To solve this problem, a support is often installed on the actuator's housing, which rests against the inner wall of the door / window frame. A set screw is then connected to the support through the inner wall of the frame to prevent tilting. However, when the distance between the housing and the inner wall of the frame is relatively large, the support can easily be pulled off the housing due to force during the tightening of the set screw, causing inconvenience during installation. Utility Model Content

[0003] Based on this, and in response to the above problems, this utility model provides a door and window actuator.

[0004] The objective of this utility model can be achieved through the following technical solutions:

The housing is mounted on the fixed plate, and the transmission component assembly is located between the fixed plate and the housing and is slidably connected to the housing. Horizontal sliding grooves are provided on both side walls of the housing. Support members that can selectively extend or retract into the sliding grooves are provided in the sliding grooves. A first threaded hole is provided on the bottom wall of the sliding groove, and a screw is provided in the first threaded hole. When the support member extends out of the sliding groove outlet end, the screw is turned so that the screw end extends into the sliding groove and abuts against the rear end of the support member.

[0006] Using the above technical solution, the support component can selectively extend or retract into the slide groove according to actual needs, allowing the actuator to adapt to different sizes and types of door and window profiles. When the distance between the outer shell and the inner wall of the door and window profile is relatively large, the support block can be pushed into the slide groove, and the support component can be fixed in the slide groove by tightening the screws. When it is necessary to push the support component out of the slide groove, first loosen the screws to push the support block out of the slide groove, and then tighten the screws so that the screw tip extends into the slide groove and abuts against the rear end of the support component to prevent the support component from retracting into the slide groove.

[0007] In a specific embodiment of this utility model: the slide groove is further provided with a stop structure to limit the support member from being pushed out of the slide groove outlet end.

[0008] In a specific embodiment of this utility model: the stop structure includes two first stop steps that are diagonally distributed at both ends of a diagonal line on the bottom wall of the slide groove, the bottom surface of the support member is provided with a second stop step that cooperates with the first stop steps, and the bottom surface of the support member is also provided with a groove that avoids the first stop steps and allows the support member to slide forward and backward.

[0009] In a specific embodiment of this utility model: the support member is provided with a through hole in the horizontal direction. The through hole is a threaded hole, which is used to fix the outer shell to the door and window profile by bolts.

[0010] In a specific embodiment of this utility model: a friction element is provided between the bottom wall of the groove and the support member.

[0011] In a specific embodiment of this utility model: the outer shell is composed of two shells that fit together, a rotatable transmission gear is installed inside the outer shell, and the transmission component group includes a first sliding block and a second sliding block that are slidably disposed inside the outer shell. The first sliding block meshes with the transmission gear, and the second sliding block is linked to the transmission gear through gear linkage.

[0012] In a specific embodiment of this utility model: both the first sliding block and the second sliding block include a horizontal part and a vertical part connected to the horizontal part, and the bottom of the vertical part is provided with teeth.

[0013] In a specific embodiment of this utility model: an installation plate is provided between the top of the outer shell and the transmission component assembly. The top of the outer shell has notches on both sides, and the two ends of the installation plate extend from the corresponding notches. The two sides of the installation plate are respectively provided with transverse grooves through which the vertical parts of the two sliding blocks can pass. The two ends of the installation plate are respectively provided with first through holes. A clamping component is connected in the first through hole, which can be inserted from the opening of the C groove of the door and window profile and can be screwed and fastened to the inside of the groove of the door and window profile.

[0014] In a specific embodiment of this utility model: the clamping member is divided into an insertion part inserted into the first through hole and a rotating part connected to the insertion part. A tool hole is provided on the upper end face of the insertion part, and a second through hole is provided on the fixing plate corresponding to the tool hole.

[0015] In summary, in this invention, the support member can selectively extend or retract into the slide groove according to actual needs, allowing the actuator to adapt to different sizes and types of door and window profiles. When the distance between the outer shell and the inner wall of the door and window profile is relatively large, the support block can be pushed into the slide groove, and the support member can be fixed in the slide groove by tightening the screws. When it is necessary to push the support member out of the slide groove, first loosen the screws to push the support block out of the slide groove, and then tighten the screws so that the end of the screw extends into the slide groove and abuts against the rear end of the support member.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 , Figure 2 and Figure 11As shown, this utility model is a door and window transmission device, which is installed on the door and window profile 9 and includes a fixing plate 10, a housing 11 and a transmission component assembly 12.

[0031] Combination Figure 5 and Figure 6 As shown, the outer casing 11 is fixedly connected to the bottom surface of the fixing plate 10. The outer casing 11 consists of two overlapping housings 111. A rotatable transmission gear 13 is installed inside the outer casing 11. A transmission assembly 12 is located between the fixing plate 10 and the outer casing 11, and includes a first sliding block 121 and a second sliding block 122 slidably disposed within the outer casing. The first sliding block 121 meshes with the transmission gear 13, and the second sliding block 122 is linked to the transmission gear 13 via a gear 123. The transmission gear 13 has a square shaft hole 131.

[0032] Combination Figure 7 and Figure 8 As shown, in this embodiment, both the first sliding block 121 and the second sliding block 122 include a horizontal portion 124 and a vertical portion 125 connected to the horizontal portion 124. The bottom of each vertical portion 125 has teeth 126.

[0033] like Figure 5 , Figure 9 , Figure 10 and Figure 11 As shown, in this embodiment, a mounting plate 14 is provided between the top of the outer casing 11 and the transmission assembly 12. The top of the outer casing 11 has notches 112 on both sides, and the two ends of the mounting plate 14 extend from the corresponding notches 112. The two sides of the mounting plate 14 are respectively provided with transverse grooves 141 through which the vertical portions of the two sliding blocks can pass. First through holes 142 are provided at both ends of the mounting plate 14. A clamping member 15 is connected within the first through hole 142, which can be inserted through the opening of the C-groove 901 of the door / window profile 9 and can be screwed and fastened to the inside of the C-groove 901 of the door / window profile 9. The clamping member 15 is divided into an insertion part 151 inserted into the first through hole and a rotating part 152 connected to the insertion part 151. A tool hole 153 is provided on the upper end face of the insertion part 151, and a second through hole 154 is provided on the fixing plate 10 corresponding to the tool hole. The mounting plate 14 and the fixing plate 11 are fixed together by bolts, such as... Figure 7 and Figure 8 The horizontal portions of the two sliding blocks are provided with transverse clearance grooves 127. Thus, when the transmission is working, the square shaft is inserted into the square shaft hole 131, and the square shaft is rotated to drive the transmission gear 13, thereby driving the first sliding block 121 and the second sliding block 122 to move.

[0034] like Figure 1 As shown, two horizontal grooves 20 are provided on the two side walls of the outer casing 11. Each groove 20 is provided with a support member 21 that can be selectively extended or retracted.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, a first threaded hole 221 is provided on the bottom wall of the slide 20. A second threaded hole 222 corresponding to the first threaded hole 221 is provided on the support member 21. Screws 23 are provided in the two threaded holes. In this way, when the support member is located in the slide 20, it can be fixed in the slide 20 by tightening the screws. When it is necessary to extend the support member 21 out of the slide 20 outlet end, first loosen the screws to push the support member out, and then tighten the screws so that the end of the screw extends into the slide 20 and abuts against the rear end of the support member to prevent the support member from retracting into the slide 20.

[0036] The slide 20 is also provided with a stop structure to limit the support from being pushed out of the slide outlet.

[0037] like Figure 3 and Figure 4 As shown, in this embodiment, the stop structure includes two first stop steps 25 diagonally distributed at both ends of a diagonal line on the bottom wall of the slide groove 20. A second stop step 26 is provided on the bottom surface of the support member 21 to cooperate with the first stop steps 25. A groove 27 is provided on the bottom surface of the support member 21 to avoid the first stop steps 25 and allow the support member 21 to slide forward and backward.

[0038] like Figure 4 As shown, in this embodiment, a through hole 28 is horizontally provided inside the support member 21. The through hole 28 is used to fix the outer shell 11 to the door and window profile 9 with bolts. The through hole 28 is a threaded hole.

[0039] In this embodiment, a friction element 29 is provided between the bottom wall of the slide 20 and the support member. The friction element increases friction to prevent the support member from falling off. The friction element is made of plastic.

[0040] The above describes the door and window transmission device of this utility model. During use, the option to extend the support member out of the slide groove is selected based on the actual application. When the distance between the outer casing and the inner wall of the door / window profile is relatively large, the support member is located within the slide groove and fixed in the groove by tightening screws to prevent it from sliding out. Subsequently, the outer casing of the transmission device is installed inside the inner cavity of the door / window profile, and the clamping member 15 is inserted into the C-groove 901. Finally, the tool is inserted into the tool hole, and rotating the tool drives the clamping member 15 to rotate, creating an interlocking structure between the rotating part of the clamping member and the C-groove 901. Figure 12 As shown, finally, bolts are used to pass the end of the bolt through the hole 902 on the wall of the door and window profile and tighten it in the through hole 28 of the support, thereby fixing the actuator to the door and window profile.

[0041] When the distance between the outer casing and the inner wall of the window / door profile requires the support to be pushed out, first unscrew screw 23 to push the support out of the groove, so that the front end of the support abuts against the inner wall of the cavity of the window / door profile 9. To push the support out, a bolt can be used to first thread it into the through hole 28 of the support 21, pull the support out, and then separate the bolt from the support 21, facilitating subsequent installation. Next, tighten screw 23 so that the screw end extends into the groove and blocks the rear end of the support. Then, install the outer casing of the actuator inside the cavity of the window / door profile, and insert clamping member 15 into groove C 901. Insert a tool into the tool hole and rotate the tool to rotate clamping member 15, so that the rotating part of the clamping member and groove C 901 form an interlocking structure. Finally, use a bolt to pass the bolt end through the hole 902 on the window / door profile wall and tighten it into the through hole 28 of the support, fixing the actuator to the window / door profile.
