[0002] Door and window locking mechanisms generally include a handle, a transmission mechanism, a connecting rod, and a handle fixing structure. During installation, the transmission mechanism and connecting rod must be connected, the handle aligned and connected to the transmission mechanism, and then secured using screws or other handle fixing structures. Finally, the handle and transmission mechanism are fixedly installed on the door and window profile. Existing thin transmission mechanisms can be directly assembled using the C-grooves on the profile, eliminating the need for re-grooving the profile, making them increasingly popular with manufacturers. However, during installation, because the transmission mechanism lacks a groove on the profile for positioning, multiple components such as the transmission mechanism, handle, and connecting rod need to be positioned simultaneously during the installation of the locking mechanism. Therefore, a single person usually cannot complete the work independently and other personnel must assist. This situation increases labor costs and adds considerable practical difficulties to the overall installation work. Utility Model Content

Detailed Implementation

[0031] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] See Figures 1-14 This embodiment discloses a conveniently installed transmission device 1, including a housing 8, a transmission component, a locking component 11, a fixing component, and a pre-positioning component 13 with elastic deformation capability. The pre-positioning component 13 can be made of silicone, plastic with a certain elastic deformation capability, or other materials, and can be used with reference to existing technology. In this embodiment, the transmission component, locking component 11, and pre-positioning component 13 are disposed in the inner cavity of the housing 8. In this embodiment, the transmission device 1 can be conveniently and quickly pre-fixed with the profile slot through the pre-positioning component 13, providing convenience for subsequent assembly. Furthermore, in this embodiment, the fixing component and the transmission device 1 are combined into a whole, so that the fixing component and the transmission device 1 are pre-fixed and positioned together, and then connected and fixed to the handle 2 through the fixing component. The conveniently installed transmission device of this embodiment is particularly suitable for thin transmission device structures, combined with, for example, Figure 1 The profile shown is used.

[0034] The prepositioning member 13 is provided with a locking part 1301 protruding to one side of the housing 8. The locking part 1301 is larger than the profile groove. The housing 8 is provided with a first clearance hole 803 for the locking part 1301 to extend out. During installation, the prepositioning member 13 deforms to cause the locking part 1301 to cross the profile groove and embed into the profile groove, thereby forming a locking position between the locking part 1301 and the profile groove.

[0035] Furthermore, the outer wall of the housing 8 is provided with a limiting block 806, which is protruding and located on the side opposite to the locking part 1301. In this embodiment, the limiting block 806 and the housing 8 can be integrally formed to form a fixed structure, while the locking part 1301 on the pre-positioning member 13 in this embodiment has a protruding structure with a certain elastic deformation capability. The two are arranged opposite each other, and after being embedded in the profile groove, the limiting block 806 and the locking part 1301 are respectively locked and locked to both sides of the profile groove, forming a stable and reliable pre-fixing effect.

[0036] Furthermore, in this embodiment, the first clearance hole 803 is provided on the side wall of the housing 8, and the locking part 1301 is located on the side of the prepositioning member 13; the bottom surface of the locking part 1301 in this embodiment is inclined to facilitate sliding over the profile groove. In addition to the cooperation between the locking part 1301 and the limiting block 806, locking parts 1301 can also be provided on both sides of the prepositioning member 13, and correspondingly, first clearance holes 803 can be provided on both sides of the housing 8, so that the structure that locks with both sides of the profile groove has elastic deformation capability.

[0037] In this embodiment, the prepositioning member 13 is provided with a retaining strip 1302. One end of the retaining strip 1302 is connected to the main body of the prepositioning member 13, and the other end of the retaining strip 1302 extends along the width direction of the housing 8. The retaining strip 1302 elastically abuts against the inner cavity of the housing 8. By setting the retaining strip 1302, the prepositioning member 13 can be stably set in the inner cavity of the housing 8, and the elasticity of the retaining strip 1302 abuts against the inner cavity of the housing 8.

[0038] Furthermore, in this embodiment, the prepositioning member 13 is provided with an adapter position 1303, which is located on the outside of the abutment strip 1302. A positioning plate 902 can be provided in the inner cavity of the housing 8 and correspondingly embedded in the adapter position 1303. On the one hand, it can form a positioning and assembly fit with the prepositioning member 13, and on the other hand, it can allow the abutment strip 1302 to elastically abut against the positioning plate 902, forming an effective elastic compression abutment effect. The positioning plate 902 can be a fixed part integral with the housing 8, or it can be a structure of other accessories inside the housing 8; for example, in this embodiment, the top clamping member 9 of the fixing component is provided with two positioning plates 902 embedded in the inner cavity of the housing 8, and the positioning plates 902 on the top clamping member 9 cooperate with the abutment strip 1302.

[0039] The prepositioning component 13 is also provided with a hollow cavity 1304, and the locking part 1301 is provided on one side of the hollow cavity 1304. By providing the hollow cavity 1304, the prepositioning component 13 can be better deformed when subjected to pressure.

[0040] In this embodiment, a first through hole 4 is provided on the side of the housing 8 corresponding to the locking part 1301. The first through hole 4 is located above the locking part 1301 and corresponds to the side wall of the pre-positioning member 13. During disassembly, a tool can be used to push open the pre-positioning member 13 through the first through hole 4, causing it to deform so that it is no longer locked to the profile groove, which facilitates the disassembly of the transmission device 1.

[0041] Along the length of the housing 8, a prepositioning member 13 is provided at one end of the inner cavity of the housing 8, and a locking assembly 11 is provided at the other end of the inner cavity of the housing 8; the locking assembly 11 includes two retractable locking members 1101, and when the two locking members 1101 move relative to each other and extend out of the side of the housing 8, they form a locking position with the profile groove.

[0042] The locking assembly 11 in this embodiment also includes an adjusting member 1102. The adjusting member 1102 is provided with an external thread, which is threadedly connected to one or two locking members 1101. When the adjusting member 1102 is rotated, it drives the two locking members 1101 to move away from or closer to each other, so as to extend or retract the housing 8. The housing 8 is provided with second clearance holes 804 on both sides for the extension of the two locking members 1101. The housing 8 is provided with a second through hole 5 on one side corresponding to the adjusting member 1102. The tool can be inserted into the inner cavity of the housing 8 through the second through hole 5 to fit the adjusting member 1102 and realize the screwing control of the adjusting member 1102.

[0043] In this embodiment, an insert portion 11021 is provided at one end of the adjusting member 1102. The adjusting member 1102 is threadedly connected to one of the locking members 1101, and the other locking member 1101 is provided with a slot 11011, in which the insert portion 11021 is located. Thus, when the adjusting member 1102 is turned, the adjusting member 1102 and the locking member 1101 move relative to each other through the threaded engagement. When the adjusting member 1102 moves, it simultaneously drives the other locking member 1101 to move, thereby achieving the synchronous approach or distance of the two locking members 1101.

[0044] As another embodiment, the external thread on the adjusting member 1102 can be configured to include two sections of threads in opposite directions, and then threaded holes that cooperate with it can be provided on each of the two locking members 1101, thereby realizing the synchronous movement of the two locking members 1101; or, some designs that can cause the two locking members 1101 to move synchronously can be provided between the two locking members 1101, as detailed in the prior art.

[0045] In this embodiment, the connection and fixation are achieved through a fixing component and the handle 2. The fixing component is located on one side of the housing 8, and the housing 8 has through holes 6 penetrating both sides of the housing 8. The fixing component corresponds to the through holes 6. In this embodiment, one side of the housing 8 has a cavity 805. In the unfixed state, the fixing component is located in the cavity 805 and forms an integral part with the transmission 1, which facilitates the initial pre-positioning and fixing. After the transmission 1 is pre-fixed to the profile, the alignment of the fixing component with the holes in the profile and the handle 2 can also be achieved simultaneously.

[0046] Specifically, the fixing component in this embodiment includes a clamping member 9 and a connecting member 10. The connecting member 10 includes a threaded section 1001 and a head 1002. The clamping member 9 has a through hole 901 for the threaded section 1001 to pass through, and the head 1002 is larger than the through hole 901. The threaded section 1001 on the connecting member 10 passes through the through hole 901 and the profile and is threadedly connected to the connection part of the handle 2. In this embodiment, two connecting members 10 are selected, and the clamping member 9 has two through holes 901 to cooperate with them. The two connecting members 10 are connected and fixed to the handle 2, which helps to improve the stability between the handle 2, the transmission device 1, and the profile. Of course, the number of connecting members 10 can also be three or other, which can be adjusted according to actual needs. The number of clamping members 9 can also be adapted to the number of connecting members 10, that is, one connecting member 10 is used with one clamping member 9. In this embodiment, a clamping member 9 is selected. In addition to a through hole 901 that mates with the connector 10, the clamping member 9 is also provided with an adapter hole for the square shaft of the handle 2 to pass through, so that the square shaft can mate with the transmission component in the transmission device 1 after passing through.

[0047] Furthermore, in this embodiment, an enlarged hole 14 is provided at one end of the through hole 6 near the cavity 805. The enlarged hole 14 is larger than the through hole 6, and a limiting step 15 is formed between the through hole 6 and the enlarged hole 14. In the unassembled state, the head 1002 of the connector 10 is located in the enlarged hole 14. This allows the head 1002 of the connector 10 to fit the housing 8 more closely, preventing the connector 10 from falling out through the through hole 6 in the unassembled state, while not affecting the subsequent screwing operation of the connector 10 by tools.

[0048] The handle 2 in this embodiment is similar to that in the prior art. A threaded hole can be provided in the base of the handle 2. The threaded section 1001 of the connector 10 passes through the through hole 901 of the clamping member 9 and engages with the threaded hole. During assembly, the tool passes through the through hole 6 on the other side of the housing 8 of the transmission 1, passes through the transmission 1, and is adapted to the head 1002 of the connector 10. Then, the connector 10 is screwed on, so that the threaded section 1001 on the connector 10 engages with the threaded hole of the handle 2, pushing the clamping member 9 to move closer to the side wall of the profile until the clamping member 9 is pressed against the side wall of the profile, thus completing the fixing of the handle 2 and the alignment and engagement of the handle 2 with the transmission 1.

[0049] In a preferred embodiment of this utility model, the transmission assembly includes a first transmission member 12 and a second transmission member 7. The first transmission member 12 is rotatably disposed in the inner cavity of the housing 8 and is used to connect with the square shaft of the handle 2. The second transmission member 7 is in transmission cooperation with the first transmission member 12. The second transmission member 7 can move relative to the housing 8. The second transmission member 7 is connected to the transmission rod 3 of the locking mechanism.

[0050] Furthermore, the transmission method, engagement method, layout method, and specific structure of the transmission components in this embodiment can all refer to the prior art. For example, the first transmission component 12 in this embodiment can be a gear structure, and the second transmission component 7 can be a transmission bar. The transmission bar is provided with a gear tooth structure that engages with the gear. When the square shaft of the handle 2 drives the gear to rotate, it can drive the transmission bar to move, thereby realizing the control of the locking mechanism.

[0051] The housing 8 in this embodiment includes a first housing cover 801 and a second housing cover 802, which are detachably connected. The second transmission member 7 is disposed between the first housing cover 801 and the second housing cover 802 and located at the top of the inner cavity. The first housing cover 801 and the second housing cover 802 limit and guide the second transmission member 7, so that the second transmission member 7 can move better under the drive of the first transmission member 12.

[0052] Preferably, the second transmission member 7 is provided with a positioning member for cooperating with the transmission rod 3 of the locking mechanism, and the positioning member protrudes towards one side of the profile groove. Specifically, in this embodiment, positioning pins 701 are provided at both ends of the second transmission member 7, and two transmission rods 3 are provided on the profile, respectively located on both sides of the transmission device 1, and the transmission rods 3 are provided with positioning holes adapted to the positioning pins 701. Through the cooperation of the positioning member and the positioning pins 701, the second transmission member 7 drives the transmission rods 3 to move. In addition, when assembling the transmission device 1, the positioning holes are first used as a reference, and the positioning pins 701 are inserted into the corresponding positioning holes to conveniently and quickly find the installation position of the transmission device 1 on the profile. Then, the pre-positioning of the transmission device 1 is completed by the deformation of the pre-positioning member 13 and the cooperation with the profile groove. Finally, the handle 2 is fixed by the fixing component.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
