[0040] Embodiment 1:

[0041] Please refer to Figures 1-3 The present application provides a door and window transmission shell, which comprises a shell 1, a bottom plate 2, a rotating piece 3, and a transmission assembly 4. The shell 1 is arranged on the bottom plate 2. One end of the rotating piece 3 is rotationally connected with the shell 1, and the other end of the rotating piece 3 is transmissionally connected with the transmission assembly 4. The transmission assembly 4 is slidingly connected with the bottom plate 2. The door and window transmission shell further comprises an elastic assembly 5. One end of the elastic assembly 5 is connected with the bottom plate 2, and the other end of the elastic assembly 5 is rotationally connected with the rotating piece 3. When the rotating piece 3 is rotated to the position, the rotating piece 3 is subjected to a positioning force generated by the elastic assembly 5.

[0042] The embodiment sets the elastic assembly 5 in the transmission shell, and tightly matches the rotating member 3 and the shell 1 through the elastic assembly 5, so that the handle does not shake after being rotated to a certain angle, the stability is strong, the rotation angle of the handle is positioned, the size of the transmission shell is adjusted to adapt to the extremely narrow frame profile, the aesthetic demand of people is met, the internal space of the transmission shell is larger, the machining difficulty of the parts is reduced, the reliability of the product is better, and the stability is stronger; and the positioning structure in the handle does not need to be considered, so that the handle can be designed more beautiful.

[0043] The working principle is as follows: when the handle and the rotating member 3 are connected through the square shaft transmission, the handle is in the initial state, and the rotating member 3 is in the shell positioning position on one side of the shell 1; when the handle is rotated, the rotation of the handle drives the rotating member 3 to rotate through the square shaft, the rotating member 3 is compressed when rotating, the elastic assembly 5 is compressed at the same time, and the resistance is generated on the rotating member 3 and transmitted to the handle; when the rotating member 3 is rotated to be in a straight line with the elastic assembly 5, the handle is continuously rotated, the elastic assembly 5 pushes the rotating member 3 to the shell positioning position on the other side of the shell 1, and tightly abuts the rotating member 3 and the shell positioning position on the other side, so as to realize the angle positioning effect of the handle.

[0044] The elastic assembly 5 will be described in detail as follows:

[0045] Please refer to Figure 4 The elastic assembly 5 includes an elastic member 6 and a guide column 7, the elastic member 6 is sleeved on the guide column 7, one end of the guide column 7 is connected with the bottom plate 2, and the other end of the guide column 7 is rotationally connected with the rotating member 3; wherein the elastic member 6 is generally selected from a spring, the elastic assembly 5 can also use a spring leaf, and a torsion spring can also be used; compared with the design of the spring leaf and the torsion spring, the design of the elastic member 6 and the guide column 7 makes the torque in the rotating process be mostly borne by the guide column 7, and the elastic member 6 only bears a small part of the torque, so that the service life of the elastic member 6 is long, and the spring leaf and the torsion spring will be deformed under the long-term action of the torque, thereby reducing the service life.

[0046] Please refer to Figure 5The guide column 7 comprises a connecting piece 8 and a supporting piece 9, the connecting piece 8 is provided with a through hole 10, one end of the supporting piece 9 is movably embedded in the through hole 10, the other end of the supporting piece 9 is connected with the bottom plate 2, the elastic piece 6 is sleeved on the supporting piece 9, one end of the supporting piece 9 is provided with a limiting portion 11, and the other end of the elastic piece 6 abuts against the limiting portion 11, the other end of the elastic piece 6 abuts against the connecting piece 8, and the connecting piece 8 is rotationally connected with the rotating piece 3. The design of the through hole 10 on the connecting piece 8 in the embodiment mainly aims to solve the problem that the sum of the length of the rotating piece 3 and the guide column 7 is constantly changed. Specifically, when the rotating piece 3 rotates from the shell positioning position on the right side of the shell 1 to the shell positioning position on the left side of the shell 1, the sum of the length of the rotating piece 3 and the guide column 7 changes from large to small and then to large. When the rotating piece 3 is in line with the guide column 7, the sum of the length of the rotating piece 3 and the guide column 7 is the smallest, and the distance between the rotating piece 3 and the shell 1 is fixed. If the sum of the length of the rotating piece 3 and the guide column 7 is unchangeable, the rotating piece 3 cannot rotate relative to the guide column 7. Therefore, the through hole 10 is arranged on the connecting piece 8, and one end of the supporting piece 9 is movably embedded in the through hole 10. In the rotating process of the rotating piece 3, the supporting piece 9 can change the sum of the length of the rotating piece 3 and the supporting piece 9 by moving in the through hole 10.

[0047] Further, the other end of the rotating piece 3 is drivingly connected with the transmission assembly 4 through the connecting piece 8, that is, the rotating piece 3 is connected with the transmission assembly 4 and the supporting piece 9 only through the connecting piece 8, so that the structure is exquisite and simple, and the manufacturing cost is reduced.

[0048] Please refer to Figure 6 The transmission assembly 4 is provided with a protrusion 12, the protrusion 12 is provided with a sliding groove 13 in the height direction, and the other end of the rotating piece 3 is movably arranged in the sliding groove 13. More specifically, the other end of the rotating piece is movably arranged in the sliding groove 13 through the connecting piece 8. The sum of the length of the rotating piece 3 and the guide column 7 is constantly changed between the transmission assembly 4 and the rotating piece 3. The sliding groove 13 is arranged in the embodiment, so that the transmission connection between the transmission assembly 4 and the rotating piece 3 is realized, and the above problem is solved.

[0049] Please refer to Figure 6 and Figure 7 In order to realize the rotational connection between the rotating piece 3 and the shell 1, the shell 1 of the embodiment is provided with a mounting hole 14, and one end of the rotating piece 3 extends out of a mounting block 15, and the mounting block 15 is rotationally arranged in the mounting hole 14.

[0050] More specifically, one end of the rotating piece 3 close to the shell 1 extends out of a mounting block 15 on each side, and the mounting block 15 is provided in the form of a circular truncated cone. The shell 1 is correspondingly provided with two circular mounting holes 14. The rotational connection between the rotating piece 3 and the shell 1 is realized by mounting the mounting block 15 in the form of a circular truncated cone in the circular mounting hole 14.

[0051] In order to realize more angle braking of the handle, the embodiment further comprises a positioning member (not shown in the figure), which is arranged on the shell 1, and the outer surface of one end of the rotating member 3 is circumferentially provided with a plurality of positioning portions 16. When the positioning member is clamped into the positioning portion 16, the positioning member and the rotating member 3 realize relative braking. Different angles of braking can be realized by clamping the positioning member into different positioning portions 16. Usually, 0 degrees, 90 degrees, and 180 degrees are provided.

[0052] Specifically, the positioning portion 16 is provided in a groove shape. The positioning member can adopt the design of the elastic member 6 and the guide column 7 of the embodiment, or the design of a spring and a needle roller, or the design of a spring and a ball.

[0053] Please refer to Figure 2 In the embodiment, the bottom plate 2 is provided with a placing groove 17, one end of the elastic assembly 5 is arranged in the placing groove 17, and the one end of the elastic assembly 5 abuts against the inner wall of the placing groove 17, that is, the placing groove 17 plays a limiting role on the one end of the elastic assembly 5. The one end of the elastic assembly 5 and the shell 1 can also be rotationally connected through hinging or other ways.

[0054] Embodiment 2:

[0055] Please refer to Figure 8 The embodiment comprises a shell 1, a bottom plate 2, a rotating member 3, and a transmission assembly 4. The shell 1 is arranged on the bottom plate 2. One end of the rotating member 3 is rotationally connected with the shell 1. The other end of the rotating member 3 is transmissionally connected with the transmission assembly 4. The transmission assembly 4 is slidingly connected with the bottom plate 2. The embodiment further comprises an elastic assembly 5. One end of the elastic assembly 5 is rotationally connected with the shell 1. The other end of the elastic assembly 5 is connected with the transmission assembly 4, so that when the rotating member 3 is rotated to a position, the rotating member 3 is subjected to a positioning force generated by the elastic assembly 5.

[0056] The working principle of the elastic assembly 5 of the embodiment is as follows. When the handle is transmissionally connected with the rotating member 3 through the square shaft, the handle is in an initial state, and the rotating member 3 is positioned at one side of the shell 1. When the handle is rotated, the handle rotation drives the rotating member 3 to rotate through the square shaft. The rotating member 3 drives the transmission assembly 4 to move when rotating. The transmission assembly 4 gradually compresses the elastic assembly 5 in the moving process. The elastic assembly 5 is compressed while generating resistance to the transmission assembly 4 and transmitting the resistance to the rotating member 3. Then the resistance is transmitted to the handle through the rotating member 3. When the elastic assembly 5 is compressed to the maximum extent, the handle is continuously rotated. The elastic assembly 5 drives the rotating member 3 to the other side of the shell 1 and tightly abuts against the other side of the shell 1, thereby realizing the effect of angle positioning of the handle.

[0057] The elastic assembly 5 comprises an elastic piece 6 and a guide column 7, the elastic piece 6 is sleeved on the guide column 7, one end of the guide column 7 is rotationally connected with the shell 1, and the other end of the guide column 7 is abutted with the transmission assembly 4.

[0058] Further, the guide column 7 comprises a connecting piece 8 and a supporting piece 9, the connecting piece 8 is provided with a through hole 10, one end of the supporting piece 9 is movably embedded in the through hole 10, the other end of the supporting piece 9 is connected with the transmission assembly 4, the elastic piece 6 is sleeved on the supporting piece 9, one end of the supporting piece 9 is provided with a limiting part 11, and one end of the elastic piece 6 is abutted with the limiting part 11, the other end of the elastic piece 6 is abutted with the connecting piece 8, and the connecting piece 8 is rotationally connected with the shell.

[0060] Since the connection between the transmission assembly 4 and the supporting piece 9 is the connection of a rod and a groove, in the rotation process, the supporting piece 9 and the containing groove 19 are constantly rubbed, thereby causing corresponding damage to the supporting piece 9 and the containing groove 19, in order to reduce such damage, please refer to Figure 10 In the embodiment, the elastic assembly 5 further comprises a mounting seat 20, the guide column 7 is rotationally connected with the mounting seat 20, the mounting seat 20 is arranged on the transmission assembly 4, the thickness of the containing groove 19 is increased by arranging the mounting seat 20, thereby reducing the damage to the containing groove 19, further, the mounting seat 20 can be made of wear-resistant material to reduce the damage of the supporting piece 9 thereto, it should be noted that the design of the mounting seat 20 can also be applied to the bottom plate 2.

[0061] In order to reduce the damage to the supporting piece 9 and the containing groove 19, the end abutted with the containing groove 19 can also be arranged in an arc shape, so that the rotation of the supporting piece 9 is more smooth, and the abutment between the supporting piece 9 and the containing groove 19 can be converted into point-face contact, thereby reducing the wear between the supporting piece 9 and the containing groove 19.
