Description

Technical Field

[0001] This invention relates to the field of doors and windows, and in particular to a detachable door and window pulley connection mechanism. Background Technology

[0002] Traditional doors and windows typically have roller modules welded or bolted to the door or window frame, and then the door or window sash is placed into the track. In traditional structures, the tracks are open, allowing dust and debris to easily fall into them, affecting the sliding of the window sash. Furthermore, open tracks are aesthetically unappealing. Therefore, to address these issues, concealed track doors and windows have become widely used. By incorporating roller mounting hardware, the width of the track is significantly reduced, improving both aesthetics and practicality.

[0003] However, in existing concealed sliding window systems, the connection between the window sash and the pulley mounting components is often inconvenient to install due to the difficulty of installing the locking components. Instead, it typically uses a method of interlocking with protrusions and grooves. For example, in the patent application CN 218816007 U, titled "An Easy-to-Install and Easy-to-Maintain Double-Row Concealed Wheel Lower Rail Structure," a left and right protrusion is respectively set on the left and right ends of the top of the I-beam frame, and a left and right fitting groove is respectively opened on the left and right profiles. The window sash is connected to the I-beam frame by fitting the left and right fitting grooves onto the left and right protrusions, respectively. This connection method has poor stability; under significant external force, the window sash is prone to detaching from the I-beam frame, causing a safety accident. Therefore, existing concealed sliding window systems suffer from technical problems related to poor stability and reliability in the connection between the window sash and the pulley module. Summary of the Invention

[0004] The purpose of this invention is to provide a detachable door and window pulley connection mechanism to solve the technical problem of poor connection stability between the window sash and the pulley module in existing concealed sliding rail windows.

[0005] A detachable door and window pulley connection mechanism includes a first connector and a second connector arranged symmetrically.

[0006] Both the first connector and the second connector have an arc-shaped groove with internal thread on their opposite surfaces, and the expansion gap between the first connector and the second connector is adjusted by connecting the connecting screw to the internal thread on the arc-shaped groove.

[0007] The first connector and the second connector are provided with a first lug protruding outward at the upper end of their opposing surfaces for engaging the lower end slot of the window sash, and the first connector and the second connector are provided with a second lug protruding outward at the lower end of their opposing surfaces for engaging the pulley mounting component.

[0008] Optionally, the pulley mounting component includes an upper connecting block and a lower connecting block;

[0009] The upper connecting block and the lower connecting block are connected by a connecting post, and the lower end of the lower connecting block is connected to the pulley module by a screw.

[0010] Optionally, the upper connecting block has a trapezoidal cross-section, and the lower end face of the window sash has a trapezoidal groove. When the pulley mounting component is connected to the window sash, the upper end of the upper connecting block fits against the end face of the trapezoidal groove.

[0011] Optionally, the lower end slot of the window sash is a first T-shaped slot formed on the upper surface of the trapezoidal groove.

[0012] Optionally, the upper end face of the upper connecting block is provided with an inverted T-shaped groove that mates with the two second lugs.

[0013] Optionally, brush mounting grooves are provided on the lower end faces of the window sashes on both sides of the trapezoidal groove, and protective brushes are installed in the brush mounting grooves.

[0014] Optionally, the front end of the connecting screw is provided with a guide bevel, and the rear end of the connecting screw is provided with an internal hexagonal hole.

[0015] Because of the adoption of the above technical solution, the present invention has the following advantages:

[0016] 1. This application connects the window sash and the pulley mounting component by setting a first connector and a second connector, and by using connecting screws to open the first connector and the second connector, so that the first lug and the second lug of the first connector and the second connector respectively engage with the first T-slot and the inverted T-slot of the window sash and the pulley mounting component, thereby improving the stability of the connection between the window sash and the pulley mounting component.

[0017] 2. This application provides a trapezoidal groove on the lower end face of the window sash and sets the upper cross section of the pulley mounting component to a trapezoidal shape. This facilitates the installation of the window sash and the pulley mounting component and increases the contact area between the window sash and the pulley mounting component. When the window sash is heavy, this greatly improves the stability and service life of the support.

[0018] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Example:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The detachable door and window pulley connection mechanism shown includes a first connector 1 and a second connector 2 arranged symmetrically.

[0029] An arc-shaped groove 3 with internal threads is provided on the opposite surfaces of the first connector 1 and the second connector 2, and the expansion gap between the first connector 1 and the second connector 2 is adjusted by connecting the connecting screw 4 to the internal threads on the arc-shaped groove 3.

[0030] First lugs 6 are provided on the upper ends of the opposite surfaces of the first connector 1 and the second connector 2, respectively, for engaging the lower end slot of the window sash 5. Second lugs 8 are provided on the lower ends of the opposite surfaces of the first connector 1 and the second connector 2, respectively, for engaging the pulley mounting component 7.

[0031] In this embodiment, the lengths of the first connector 1, the second connector 2, and the pulley mounting component 7 are all the same as or slightly less than the length of the window sash 5, and the lengths of the two arc-shaped grooves 3 are greater than the lengths of the connecting screws 4.

[0032] In this embodiment, when machining the arc-shaped groove 3 and the internal thread, the first connector 1 and the second connector 2 are clamped relative to each other so that the distance between their symmetrical planes is M. Then, the arc-shaped groove 3 is drilled simultaneously on the first connector 1 and the second connector 2 using a drill bit. Finally, the internal thread is machined simultaneously on the arc-shaped groove 3 on both sides using a thread machining tool.

[0033] like Figure 1 and Figure 3 As shown, the pulley mounting component 7 includes an upper connecting block 701 and a lower connecting block 702;

[0034] The upper connecting block 701 and the lower connecting block 702 are connected by a connecting post 703, and the lower end of the lower connecting block 702 is connected to the pulley module 9 by a screw.

[0035] In this embodiment, during window sash 5 installation, the lower connecting block 702 and pulley module 9 are concealed within a sliding groove, and the connecting post 703 passes through the upper opening of the concealed sliding groove. By setting the pulley mounting component 7 into an I-shaped structure, the width of the upper opening of the concealed sliding groove is reduced, improving aesthetics and reducing the possibility of dust and foreign objects falling into the sliding groove.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the upper end cross section of the upper connecting block 701 is trapezoidal, and a trapezoidal groove 10 is provided on the lower end surface of the window sash 5. When the pulley mounting part 7 is connected to the window sash 5, the upper end of the upper connecting block 701 is in contact with the end face of the trapezoidal groove 10.

[0037] In this embodiment, by opening a trapezoidal groove 10 on the lower end face of the window sash 5 and setting the upper end cross section of the pulley mounting component 7 as a trapezoid, it is not only convenient to install the window sash 5 and the pulley mounting component 7, but also increases the contact surface between the window sash 5 and the pulley mounting component 7. When the window sash 5 is heavy, it greatly improves the stability and service life of the support.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the lower end slot of the window sash 5 is a first T-shaped groove 11 opened on the upper end surface of the trapezoidal groove 10, and the upper end surface of the upper connecting block 701 is provided with an inverted T-shaped groove 12 that cooperates with the two second lugs 8.

[0039] In this embodiment, a first T-shaped groove 11 is provided to engage with a first lug 6, and an inverted T-shaped groove 12 is provided to engage with a second lug 8.

[0040] like Figure 1 and Figure 4 As shown, brush mounting grooves 13 are provided on the lower end faces of the window sashes 5 on both sides of the trapezoidal groove 10, and protective brushes 14 are installed in the brush mounting grooves 13.

[0041] In this embodiment, by setting a sealed protective brush 14, the protective brush 14 contacts the upper surface of the window frame during installation, which improves the sealing performance and reduces dust falling into the concealed groove. The length of the protective brush 14 is the same as the length of the window sash 5.

[0042] like Figure 5 As shown, the front end of the connecting screw 4 is provided with a guide bevel 401, and the rear end of the connecting screw 4 is provided with an internal hexagonal hole 402.

[0043] In this embodiment, by setting the guide angle 401, the connecting screw 4 can easily open the first connecting piece 1 and the second connecting piece 2 on both sides. By setting the internal hexagonal hole 402, the connecting screw 4 will not protrude from the outer dimension of the window sash, thus improving the aesthetics and the sealing performance of the window sash.

[0044] In this embodiment, the specific installation steps are as follows:

[0045] S1: First, remove the upper cover plate of the window frame slide (not shown in the figure), install several pulley modules 9 at intervals at the bottom of the lower connecting block 702, then put the pulley mounting piece 7 and several pulley modules 9 into the window frame slide, and cover the upper cover plate of the window frame slide.

[0046] S2: Place the window sash 5 onto the upper connecting block 7. At this time, the trapezoidal groove 10 fits against the upper end face of the upper connecting block 7. Insert the first connecting piece 1 and the second connecting piece 2, which are symmetrically assembled, from the side.

[0047] S3: Screw the connecting screw 4 into the inner arc-shaped groove 3. The connecting screw 4 opens the first connector 1 and the second connector 2, so that the first lug 6 on the first connector 1 and the second connector 2 abuts against the side of the first T-shaped groove 11, and the second lug on the first connector 1 and the second connector 2 abuts against the side of the inverted T-shaped groove 12, thereby improving the stability and reliability of the connection.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
