DETAILED DESCRIPTION

[0024] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application. Moreover, the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0025] Figure 1 The overall structural schematic diagram of the transmission device 100 according to an embodiment of the present application is shown, Figure 2 The exploded structural schematic diagram of the transmission device 100 is shown. Referring to Figure 1 and Figure 2 It is shown that the transmission device 100 mainly comprises a transmission main body 10 and a first clamping assembly 20 and a second clamping assembly 30 respectively arranged at two ends of the transmission main body 10 in the extension direction of the transmission main body 10, the transmission main body 10 is used to convert the rotation of a door and window handle into linear motion in the extension direction of the transmission main body 10, and the first clamping assembly 20 and the second clamping assembly 30 are used to mount the transmission main body 10 in the slot 201 of the door and window profile 200 (see Figure 5 and Figure 6 ).

[0026] Referring in particular to Figure 2As shown, the transmission main body 10 comprises a first housing 11 and a second housing 12 combined together and a transmission assembly 13 arranged in the space enclosed by the first housing 11 and the second housing 12. The transmission assembly 13 converts the rotation of the door and window handle around the axially extending shaft into the linear motion of the transmission main body 10 in the left-right direction, so as to control the opening and locking of the door and window lock. The specific implementation of the transmission assembly 13 can adopt various suitable technical means, which is not the focus of the present application, and will not be described in detail here. Referring to Figure 2 As shown, the first housing 11 and the second housing 12 enclose a first sliding groove 14 extending upward and downward at one end and a second sliding groove 15 extending upward and downward at the other end, the first clamping assembly 20 is provided with a first sliding block 21 sliding in the first sliding groove 14, and the second clamping assembly 30 is provided with a second sliding block 31 sliding in the second sliding groove 15, so that the transmission main body 10 can slide upward and downward relative to the first clamping assembly 20 and the second clamping assembly 30 through the cooperation of the first sliding groove 14 and the first sliding block 21 and the second sliding groove 15 and the second sliding block 31. Referring to Figure 2 In combination Figure 5 As shown, the bottom inner side of the first sliding block 21 is provided with a first spring support seat 22, and a first positioning column 23 protruding upward is preferably arranged on the first spring support seat 22, the top of the first sliding groove 14 opposite to the first spring support seat 22 forms a first spring mounting cavity 16, and the first clamping assembly 20 is further provided with a first spring 24 extending upward and downward, the lower end of the first spring 24 is sleeved on the first positioning column 23 and abuts against the first spring support seat 22, and the upper end of the first spring 24 is accommodated in the first spring mounting cavity 16 and abuts against the top of the first spring mounting cavity 16. Similarly, referring to Figure 2 In combination Figure 6As shown, the bottom of the second slider 31 of the second clamping assembly 30 is provided with a second spring support seat 32 on the opposite inner side, and a second positioning column 33 protruding upward is preferably arranged on the second spring support seat 32. The top of the second sliding groove 15 is opposite to the second spring support seat 32 to form a second spring mounting cavity 17. The second clamping assembly 30 is further provided with a second spring 34 extending upward and downward. The lower end of the second spring 34 is sleeved on the second positioning column 33 and abuts against the second spring support seat 32. The upper end of the second spring 34 is accommodated in the second spring mounting cavity 17 and abuts against the top of the second spring mounting cavity 17. In this way, when the transmission body 10 is pressed to make the transmission body 10 slide downward relative to the first clamping assembly 20 and the second clamping assembly 30 through the cooperation of the first sliding groove 14 and the first slider 21 and the second sliding groove 15 and the second slider 31, the first spring 24 and the second spring 34 are compressed. After the pressing of the transmission body 10 is released, the transmission body 10 can slide upward relative to the first clamping assembly 20 and the second clamping assembly 30 to reset under the elastic force of the first spring 24 and the second spring 34. After the transmission device 100 is installed in the slot 201 of the profile 200 through the first clamping assembly 20 and the second clamping assembly 30, the transmission body 10 can be slid into the slot 201 relative to the first clamping assembly 20 and the second clamping assembly 30 by pressing the transmission body 10, so as to align the transmission assembly in the transmission body 10 with the handle installation position on different door and window profiles to facilitate the installation of the handle.

[0027] Referring again to Figure 3 In combination Figure 5 As shown, the first clamping assembly 20 further includes a fixed block 25, a driving slider 26, a clamping slider 27, a reset spring 28 and an adjusting screw 29. The fixed block 25 is fixedly connected to the outer side of the first slider 21 and extends out of the transmission body 10. The fixed block 25 and the first slider 21 further form an avoiding groove 253 extending upward from the bottom to slide and insert the end plate 18 outside the first sliding groove 14 of the transmission body 10. The lower part of the fixed block 25 forms a sliding cavity 252, and the upper outer end of the fixed block 25 forms a fixed outer edge 251. The clamping slider 27 is arranged in the sliding cavity 252 of the lower part of the fixed block 25 in a left-right slidable manner through the sliding adjusting structure composed of the adjusting screw 29, the driving slider 26 and the reset spring 28. The outer end of the clamping slider 27 forms a first clamping inclined surface 271 opposite to the fixed outer edge 251, which are used to clamp one side of the slot 201 of the profile 200. For details, see Figure 3 In combination Figure 5As shown, the clamping slider 27 is slidingly arranged in the sliding cavity 252, and the fixed block 25 is further provided with a limiting guide column 255 extending downward into the sliding cavity 252 and penetrating the clamping slider 27 to cooperate with the guide sliding slot 273 formed therein, thereby guiding the clamping slider 27 to slide leftward and rightward in the sliding cavity 252. The clamping slider 27 is further formed with a receiving groove 274 at the inner side of the lower end of the guide sliding slot 273, and the inner end of the leftward and rightward extending reset spring 28 is abutted in the receiving groove 274 and the outer end is abutted with the limiting guide column 255, thereby realizing the reset of the clamping slider 27 after sliding outward relative to the fixed block 25. The driving slider 26 is slidingly arranged at the inner side of the clamping slider 27 in the sliding cavity 252, and the outer side of the driving slider 26 is formed with the first driving inclined surface 262 which is in abutment with the second driving inclined surface 272 formed at the inner side of the clamping slider 27. The adjusting screw 29 extends into the sliding cavity 252 from the upper side of the fixed block 25 through the through hole 254 on the fixed block 25 and is in threaded connection with the adjusting screw hole 261 correspondingly arranged on the driving slider 26. The bottom plate 256 is further fixedly arranged at the bottom of the sliding cavity 252 of the fixed block 25, thereby closing the bottom of the sliding cavity 252 and preventing the driving slider 26 and the clamping slider 27 from being detached from the bottom of the sliding cavity 252. Thus, referring to Figure 5 As shown, when the adjusting screw 29 is rotated to move the driving slider 26 upward in the sliding cavity 252 along the axial direction of the adjusting screw 29, the driving slider 26 acts on the second driving inclined surface 272 of the clamping slider 27 through the first driving inclined surface 262, thereby pushing the clamping slider 27 to slide outward along the sliding cavity 252, and the first clamping inclined surface 271 at the outer end of the clamping slider 27 extends out of the sliding cavity 252 and cooperates with the fixed outer edge 251 to clamp the corresponding side of the slot 201 of the profile 200. When the adjusting screw 29 is reversely rotated to move the driving slider 26 downward, the clamping slider 27 can slide inward to reset under the elastic force of the reset spring 28, and the first clamping inclined surface 271 is withdrawn into the sliding cavity 252 and no longer clamps the slot 201. In order to avoid the interference between the adjusting screw 29 and the clamping slider 27 during the upward and downward movement of the driving slider 26, the clamping slider 27 is further formed with the avoiding gap 275 (see Figure 3 ) extending upward and downward at the end opposite to the driving slider 26 for the adjusting screw 29 to pass through.

[0028] Further referring to Figure 4 In combination with Figure 6 As shown, the second clamping assembly 30 is further provided with the fixed sheet 35 and the clamping sheet 36 which are fixedly connected to the outer side of the second slider 31 and extend out of the transmission main body 10. The outer end of the clamping sheet 36 is formed with the second clamping inclined surface 361 for cooperating with the fixed sheet 35 to clamp the corresponding other side of the slot 201 of the profile 200.

[0029] When the transmission device 100 according to the above embodiment of the present application is installed in the slot 201 of the door and window profile 200, referring toFigure 6 As shown, first, the transmission main body 10 is placed into the slot 201, and the second clamping inclined surface 361 of the fixed piece 35 and the clamping piece 36 of the second clamping assembly 30 is matched to clamp the corresponding side of the slot 201. Then, as shown, Figure 5 As shown, the fixed outer edge 251 of the fixed block 25 of the first clamping assembly 20 is placed on the upper part of the other side of the slot 201, and then the adjusting screw 29 is rotated to make the clamping sliding block 27 slide outward to extend the first clamping inclined surface 271, which is matched with the fixed outer edge 251 to clamp the other side of the slot 201, so that the transmission 100 is installed on the slot 201 through the first clamping assembly 20 and the second clamping assembly 30. The adjusting screw 29 is reversely rotated to make the clamping sliding block 27 slide inward to reset under the elastic force of the reset spring 28, and the first clamping inclined surface 271 is retracted into the sliding cavity 252, so that the transmission 100 can be disassembled. The first clamping assembly 20 and the second clamping assembly 30 designed in this way not only make the transmission 100 convenient and fast to disassemble and assemble, but also can adjust the distance of the first clamping inclined surface 271 of the clamping sliding block 27 of the first clamping assembly 20 extending out of the sliding cavity 252 to clamp the slot according to the slots of profiles with different lengths and different thicknesses, so as to improve the product compatibility of the transmission 100. According to different embodiments of the present application, the second clamping assembly 30 can also adopt the same clamping length adjustable structure as the first clamping assembly 20, so that the transmission can be applied to a larger range of profile slot sizes.

[0030] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
