[0025] like Figure 1 and Figure 2 As shown, a casement door and window lifting structure described in the utility model includes a roller seat 1, and at least one elastic buckle portion 11 is respectively arranged on the front and rear ends of the bottom of the roller seat 1, and the buckle bodies of the elastic buckle portions 11 on the front and rear ends of the roller seat 1 are made to face opposite directions.

[0026] In the casement door and window lifting structure, at least one elastic buckle part 11 is provided on the front and rear ends of the bottom of the roller seat 1, and the buckle bodies of the elastic buckle parts 11 on the front and rear ends of the roller seat 1 face opposite directions. This can not only utilize the elasticity of the elastic buckle part 11 to quickly achieve buckle installation and positioning, but also facilitate stable and reliable installation and positioning effects. Such a casement door and window lifting structure is very simple and convenient to install and position, and does not require a hole puncher, screwdriver or wrench, etc. It can greatly improve the convenience and efficiency of installation and positioning, and ordinary users can also quickly achieve installation, which can solve a lot of troubles for ordinary users.

[0027] like Figure 2 , Figure 4 and Figure 6 As shown, in the actual manufacturing process, the number of elastic buckle parts 11 on the front and rear ends of the roller seat 1 is equal, and there is an elastic buckle part 11 corresponding to the elastic buckle part 11 on the front end of the roller seat 1. This can have a more stable and reliable buckle effect, which can help further improve the stability and reliability of the installation and positioning of the casement door and window lifting structure.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, the casement door and window lifting structure further includes a roller 2 and a positioning cover 3. The roller 2 is provided with convex shaft portions 21 at both ends, and the two convex shaft portions 21 are embedded in the roller seat 1. The positioning cover 3 is mounted on the roller seat 1, and the positioning cover 3 simultaneously restricts the two convex shaft portions 21 on the roller seat 1. In this way, the roller 2 can be installed conveniently and stably, which not only facilitates assembly, but also ensures that the casement door and window lifting structure has high reliability.

[0029] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, a clearance groove 12 is provided on the top of the roller seat 1, and positioning notches 121 are respectively provided on two opposite notch edges of the clearance groove 12, and two convex shaft portions 21 are respectively embedded in the two positioning notches 121, and the positioning cover 3 is simultaneously installed on the upper notches of the two positioning notches 121. In this way, the roller 2 can be more accurately and stably limited on the roller seat 1, thereby helping to further improve the accuracy and stability of the installation and positioning of the roller 2, and further helping to further improve the reliability and applicability of the casement door and window lifting structure.

[0030] In the actual manufacturing process, in order to meet the rolling requirements of the roller 2, the following structures can be adopted: the first one, the roller 2 can be rolled on the middle part of a shaft body, and the two ends of the shaft body respectively constitute two convex shaft parts 21; the second one, the roller 2 is fixedly mounted on the middle part of a shaft body, and the two ends of the shaft body respectively constitute two convex shaft parts 21, and the two convex shaft parts 21 can be rolled and embedded in the positioning notch 121; the third one, the two convex shaft parts 21 are integrally formed on the end faces of the two ends of the roller 2, and the two convex shaft parts 21 can be rolled and embedded in the positioning notch 121. In this way, the rolling requirements of the roller 2 can be met, and thus the actual manufacturing and use requirements can be met.

[0031] like Figure 1 and Figure 3 As shown, a vertically penetrating clearance hole 31 is provided in the middle of the positioning cover 3, and the two ends of the positioning cover 3 are respectively covered on the upper notches of the two positioning notches 121, and the top of the roller 2 protrudes out of the clearance hole 31. This not only helps the positioning cover 3 to have a simple structure, but also helps the positioning cover 3 to play a more stable and reliable positioning role for the roller 2, thereby further improving the stability and reliability of the installation and positioning of the roller 2.

[0032] like Figure 3 and Figure 4 As shown, the roller 2 is an axial roller, which not only helps to improve the structural strength of the roller 2, but also increases the contact area, thereby greatly reducing the probability of damage during use, and further helps to extend the service life.

[0033] like Figure 1 , Figure 7 and Figure 8 As shown, in order to avoid making the roller seat 1 too thick or reduce the influence of the positioning notch 121 on the structural strength of the roller seat 1, a semicircular positioning notch 121 can be opened on the roller seat 1, and an arc-shaped buckle cover portion 32 covering the top of the convex shaft portion 21 can be made on the positioning cover 3.

[0034] like Figure 1 , Figure 3 and Figure 5 As shown, a hidden groove 13 is provided on the top surface of the roller seat 1, the giving way groove 12 is located at the middle of the groove bottom of the hidden groove 13, the two positioning notches 121 are both located at the groove bottom of the hidden groove 13, and the positioning cover 3 is embedded in the hidden groove 13. The use of the hidden groove 13 can not only enhance the stability and reliability of the installation and positioning of the positioning cover 3, but also make the casement door and window lifting structure have a very compact structure, which can be used in a smaller space, thereby helping to further improve the reliability and applicability of the casement door and window lifting structure.

[0035] like Figures 2 to 8 As shown, the clearance groove 12 penetrates the bottom surface of the roller seat 1, and the two ends of the bottom surface of the positioning cover 3 are respectively provided with plug-in hooks 33 with buckle bodies facing opposite directions, and the two plug-in hooks 33 are buckled on the lower end of the clearance groove 12. This can not only meet the requirements of stable installation of the positioning cover 3, but also facilitate the removal of the positioning cover 3, so that the roller 2 can be easily disassembled for maintenance, which helps to further improve the convenience of maintenance.

[0036] like Figure 2 and Figure 6 As shown, two opposite notch edges at the lower end of the said giving way groove 12 are respectively provided with hooking grooves 122 for two hooking hooks 33 to hook. This not only facilitates the hooking of the hooking hooks 33, but also facilitates the inspection of whether the hooking hooks 33 are hooked. When the positioning cover 3 is disassembled, it is convenient to act on the hooking hooks 33 from the outside, so that the hooking hooks 33 can be easily separated from the hooking grooves 122, which helps to further improve the convenience of disassembly and maintenance.

[0037] Since the roller 2 needs to roll in contact and directly bear pressure, the roller 2 wears and deforms faster than other components. The above-mentioned assembly structure can meet the purpose of replacing the roller 2 alone. There is no need to replace the entire casement door and window lifting structure when the roller 2 is worn or deformed, which can help reduce maintenance costs.

[0038] like Figure 5 As shown, a guiding slope 14 is provided on the top edge of the roller seat 1. The guiding slope 14 can guide the door and window sash or the contact block arranged on the door and window sash to avoid the situation of hindering the closing of the door and window sash, which helps to further improve the applicability of the casement door and window lifting structure.

[0039] In actual use, the bottom of the door and window sash can directly act on the guide slope 14 and the roller 2, or a contact block can be set at the bottom of the door and window sash to indirectly contact the guide slope 14 and the roller 2 through the contact block, thus meeting the actual use needs.

[0040] like Figure 6 As shown, at least one reinforcement column 15 is provided on the middle part of the bottom surface of the roller seat 1. During installation, the reinforcement column 15 can support and position the roller seat 1, thereby enhancing the bearing capacity of the roller seat 1, thereby helping to further improve the reliability and applicability of the casement door and window lifting structure.

[0041] like Figure 6 As shown, the reinforcing column 15 is a hollow reinforcing column 15, and part of the reinforcing column 15 is located directly below the convex shaft portion 21. The reinforcing column 15 has elastic buckle portions 11 at the front and rear, and the upper end of the elastic buckle portion 11 is connected to the reinforcing column 15. The front and rear of the lower end of the reinforcing column 15 are respectively recessed to form a clearance notch 151 for the lower end of the corresponding elastic buckle portion 11 to swing in and out. This can not only control the use of raw materials, but also make the casement door and window lifting structure have a more stable and reliable structure, thereby helping to further improve the reliability and applicability of the casement door and window lifting structure.

[0042] like Figure 6 As shown, there are two reinforcing columns 15, which are respectively located on both sides of the notch of the clearance groove 12, and the parts of the two reinforcing columns 15 are respectively located directly below the two convex shaft parts 21. This can play a more stable and reliable reinforcing role, thereby further improving the reliability of the casement door and window lifting structure.

[0043] like Figure 5 and Figure 6 As shown, the casement door and window lifting structure further includes a positioning piece 4, one end of which is connected to the roller seat 1 and / or the reinforcing column 15, and at least one through hole 41 is formed on the positioning piece 4. When used on heavy casement doors and windows, the positioning piece 4 can be fixed to the door and window frame by screws passing through the through hole 41, which can further improve the stability and reliability of the installation and positioning of the casement door and window lifting structure, so that the casement door and window lifting structure can withstand greater impact, and can be used very well on heavy casement doors and windows.

[0044] like Figure 5 As shown, the top surface of the positioning piece 4 is an anti-skid surface with anti-skid grooves and / or anti-skid protrusions, which can reduce the probability of the screw loosening, thereby ensuring that the screw locking is very stable and reliable.

[0045] like Figure 5 and Figure 6 As shown, the through hole 41 is a waist-shaped hole, which can facilitate the adjustment of the locking position of the screw, thereby facilitating a good locking effect.

[0046] like Figure 6As shown, at least one buckling portion 42 is provided on each side of the positioning piece 4. The buckling portion 42 can play a role of buckling and positioning, thereby facilitating the stability of the installation and positioning of the positioning piece 4, thereby further helping to further improve the reliability and applicability of the casement door and window lifting structure.

[0047] like Fig. 9 As shown, in actual application, a door and window frame 10 with a transversely extending T-shaped slot 101 on the top surface is used; during installation, the elastic buckle parts 11 on the front and rear ends of the roller seat 1 are inserted into the T-shaped slot 101, and the front and rear elastic buckle parts 11 are respectively buckled on the front and rear slot walls of the T-shaped slot 101; the positioning piece 4 is placed in the T-shaped slot 101, and the buckling parts 42 on the side edges of the positioning piece 4 are respectively buckled on the front and rear slot walls of the T-shaped slot 101; the positioning piece 4 is fixed to the door and window frame 10 after passing through the through hole 41 with a screw (not shown in the figure), so that the installation positioning and use requirements of the casement door and window lifting structure can be met.
