[0036] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0037] On the one hand, such as Figure 1 and Figure 2 As shown, a snap-on lifting block in one embodiment of the present invention includes:

[0038] The base 1 has a snap-fit ​​mounting structure at the bottom, which includes a first snap-fit ​​flange 11 adapted to the snap-fit ​​groove of the window frame, a limiting flange 12 adapted to the snap-fit ​​groove surface of the window frame, and a mounting groove 13.

[0039] The elastic clip 2 is provided with a mounting part 21 disposed in the mounting groove 13 and a second snap-fit ​​end 22 adapted to the window frame snap-fit ​​groove;

[0040] The rolling contact unit 3 is disposed on the top of the base 1.

[0041] The aforementioned snap-on lifting block is fixed to the window frame by snapping the first snap-on flange 11 onto one side of the window frame snap-on groove, and then snapping the second snap-on end 22 of the elastic snap-on member 2 into the other side of the window frame snap-on groove until the limiting flange 12 touches the top of the window frame snap-on groove; at the same time, the rolling contact unit 3 and the bottom of the window sash roll against each other to achieve a lifting effect. The structure is simple and the assembly operation is time-saving and labor-saving.

[0042] Specifically, the snap-on lifting block has the following advantages:

[0043] Easy Installation: The snap-on quick-install design of doors and windows simplifies the installation process. Installation is achieved quickly via snap-on mechanisms, eliminating the need for complex on-site processing and adjustments, significantly saving installation time and labor costs. For example, some quick-install hinges use a snap-on design, requiring no screws or tools for rapid installation and disassembly. This also applies to snap-on quick-install lifting blocks for doors and windows, improving work efficiency.

[0044] Easy maintenance: Due to its relatively simple structure, the quick-release lifting block for doors and windows is easier to maintain. Regular inspections, cleaning, and lubrication can be performed more efficiently.

[0045] Durability: Made with high-quality materials and manufacturing processes, the door and window snap-on lifting blocks are highly durable and can withstand long-term use and harsh environmental conditions.

[0046] Flexibility: If there is an error in the positioning of the quick-release lifting block during the installation process, it can be directly pried off and re-clamped into the groove. The stainless steel elastic clips have sufficient elasticity, making disassembly and installation convenient.

[0047] Higher installation efficiency: As mentioned earlier, the installation process of the door and window snap-on quick-installation lifting block is simpler and faster, without the need for complicated on-site processing and debugging, which greatly improves installation efficiency.

[0048] Enhanced safety: Equipped with safety protection devices, it can more effectively prevent accidents and protect the safety of people and property.

[0049] Lower maintenance costs: Due to its relatively simple structure and high durability, the maintenance cost of the quick-installation lifting block for doors and windows is also relatively low.

[0050] Wider range of applications: Door and window snap-on quick-installation lifting blocks may support more operating methods and configuration options, making them adaptable to more different usage scenarios and needs.

[0051] In conclusion, compared with traditional screw-on lifting blocks, snap-on quick-installation lifting blocks for doors and windows offer significant advantages in terms of ease of installation, safety, ease of maintenance, durability, and flexibility. These advantages have led to the increasingly widespread application of snap-on quick-installation lifting blocks in modern construction and industrial fields.

[0052] In one embodiment, the rolling contact unit 3 includes a roller 31 rotatably connected to the base 1. Specifically, the roller contact surface of the roller 31 is at least 4 mm higher than the top of the base 1.

[0053] In one embodiment, the base 1 is provided with a mounting groove 14, and the roller component 31 is mounted in the mounting groove 14; the rolling contact unit 3 further includes a plastic retaining block 32 for confining the roller component 31 within the mounting groove 14. Thus, by confining the roller component 31 within the mounting groove 14 by the plastic retaining block 32, the roller component 31 can roll freely on the base 1.

[0054] In one embodiment, the roller component 31 is a brass pulley, comprising a wheel body and mounting shafts at both ends of the wheel body; the mounting groove 14 has a semi-circular groove adapted to the mounting shaft, and the plastic locking block 32 includes a limiting groove adapted to the mounting shaft and a locking flange for engaging with the base 1. Thus, after the mounting shaft is positioned by the limiting groove of the plastic locking block 32, it is engaged with the base 1 by the locking flange, thereby achieving the rolling installation of the roller component 31.

[0055] In one embodiment, the first engaging flange 11 has an arc-shaped tip. This arc-shaped tip facilitates the engagement of the first engaging flange 11 into the limiting groove.

[0056] In one embodiment, the mounting groove 13 has an L-shaped cross-section, including a vertical groove and a horizontal groove; the mounting part 21 includes an inverted L-shaped hook 211 disposed in the vertical groove and a spring-loaded arc 212 that presses against the wall of the horizontal groove. Thus, by the inverted L-shaped hook 211 engaging in the vertical groove and the spring-loaded arc 212 pressing against the wall of the horizontal groove, the elastic clip 2 is pressed onto the base 1.

[0057] In one embodiment, the elastic clip 2 is formed by bending a stainless steel strip. Specifically, the stainless steel strip is an elastic stainless steel strip. Thus, using a stainless steel strip to process the elastic clip 2 simplifies the manufacturing process and reduces processing costs.

[0058] In one embodiment, the base 1 is machined from an aluminum alloy block.

[0059] On the other hand, such as Figure 3 As shown, a door and window in one embodiment of the present utility model is characterized by including a window frame 4, a window sash 5, and a snap-on lifting block 6. The window frame 4 is provided with a snap-on groove 41 adapted to the snap-on installation structure; the bottom of the window sash 5 is provided with a top block 51 adapted to the snap-on lifting block 6.

[0060] In one embodiment, the inlet of the snap-fit ​​groove 41 is provided with an installation ramp. Thus, by providing the installation ramp, it is easier for the first snap-fit ​​flange 11 to snap into the snap-fit ​​groove 41.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
