Description

Technical Field

[0001] This utility model relates to the technical field of hand-cranked window openers, specifically to a crank guide sleeve for a hand-cranked window opener. Background Technology

[0002] Many buildings and factories have numerous windows, some of which are difficult to open, requiring window openers. Existing hand-cranked window openers consist of a housing installed at the window, a right-angle steer, and a mechanism and chain box installed inside the housing. Installation involves first fixing the housing to the window, then connecting the right-angle steer to the hexagonal shaft of the mechanism inside the housing via a connecting rod, and finally fixing the right-angle steer. Due to the large size of the windows, the relative positions of the housing and the right-angle steer are relatively far, the connecting rod and the hexagonal shaft are connected by a socket joint, and the hexagonal shaft of the mechanism is not directly visible inside the window opener housing, making it difficult to connect the right-angle steer and the mechanism, and difficult to accurately insert the hexagonal shaft in a short time, resulting in assembly difficulties. Therefore, this invention provides a hand-cranked window opener crank guide sleeve that facilitates the connection between the right-angle steer connecting rod and the hexagonal shaft of the mechanism. Utility Model Content

[0003] The purpose of this invention is to provide a crank guide sleeve for a hand-cranked window opener.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] A hand-cranked window opener crank guide sleeve includes: an insert, a connecting part, and a sleeve part;

[0006] The embedding part is fixedly embedded in the chain box of the hand-cranked window opener; the connecting part is used to connect the embedding part and the sleeve part.

[0007] The sleeve portion has a hollow cylindrical structure and is fitted outside the hexagonal shaft of the mechanism. The distance between the hexagonal shaft of the mechanism and the sleeve portion is less than the cross-sectional dimension of the right-angle steering gear connecting rod. One end of the sleeve portion extends to the end of the hand-cranked window opener housing.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme, the cross-section of the embedded part is an inverted trapezoid, which is embedded from top to bottom into the chain box of the hand-cranked window opener.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme, the connecting part is L-shaped, one end of the horizontal side of the L-shape is connected to the embedding part, the vertical side of the L-shape extends downward from the horizontal side, and the bottom is connected to a slanted side; the slanted side is fixedly connected to the sleeve part; the horizontal side and the vertical side cooperate with the embedding part to clamp the chain box of the hand-cranked window opener.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme, an extension plate is provided at the bottom of the vertical side; the extension plate extends toward the embedded part to the chain box of the hand-cranked window opener.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme, the sleeve portion opens towards the embedded portion, making its cross-section C-shaped; the upper end of the sleeve portion opening is connected to the inclined side.

[0012] Based on the above solution and as a preferred embodiment of the above solution, the embedding part, the connecting part, and the sleeve part are integrally formed.

[0013] Based on the above solution and as a preferred embodiment of the above solution, the embedding part, the connecting part, and the sleeve part are all made of nylon.

[0014] The beneficial effects of this utility model are as follows: The guide sleeve provided by this utility model is fixed to the chain box inside the shell of the hand-cranked window opener by embedding, which is convenient to connect and simple to assemble, without increasing the overall assembly difficulty. The structure of this utility model is simple and can be perfectly integrated into the shell of the hand-cranked window opener without affecting the use of the hand-cranked window opener. The sleeve part is fitted outside the hexagonal shaft of the model. When connecting the connecting rod of the right-angle steering gear and the hexagonal shaft, the connecting rod first enters into the sleeve part. Due to the restriction of the sleeve part, the connecting rod can be easily fitted onto the hexagonal shaft, which can improve the assembly efficiency of the hand-cranked window opener. At the same time, since the end of the sleeve part extends to the end of the shell of the hand-cranked window opener, the operator can see the sleeve part with the naked eye, which makes it convenient to insert the connecting rod into the sleeve part, making the connection more convenient.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown,

[0023] A hand-cranked window opener crank guide sleeve includes: an embedded part 1, a connecting part 2, and a sleeve part 3.

[0024] The embedding part 1 is embedded in the chain box 11 of the hand-cranked window opener to fix the entire guide sleeve. Specifically, the embedding part 1 has an inverted trapezoidal cross section and is embedded from top to bottom in the chain guide rail of the chain box 11 of the hand-cranked window opener.

[0025] The connecting part 2 is used to connect the embedded part 1 and the sleeve part 3. Preferably, the connecting part 2 is L-shaped, with one end of the horizontal side of the L-shape connected to the embedded part 1, and the vertical side of the L-shape extending downward from the horizontal side, with a sloping side connected to the bottom. The sloping side is fixedly connected to the sleeve part 3. The horizontal side and the vertical side cooperate with the embedded part 1 to clamp the chain guide rail of the hand-cranked window opener chain box 11, realizing the connection between the guide sleeve and the chain box. The sloping side extends downward from the bottom of the vertical side.

[0026] like Figure 2 As shown, in another embodiment, an extension plate 4 is provided at the bottom of the vertical side. The extension plate 4 extends toward the embedded part 1 to the chain box 11 of the hand-cranked window opener to improve the connection stability between the guide sleeve and the chain box and prevent the guide sleeve from moving upward. During connection, the guide sleeve slides in from the side of the chain box.

[0027] like Figure 3 and Figure 4 As shown, the sleeve portion 3 has a hollow cylindrical structure and is fitted onto the outside of the hexagonal shaft 2 of the movement. The distance between the hexagonal shaft 12 of the movement and the sleeve portion 3 is smaller than the cross-sectional dimension of the right-angle steering gear connecting rod, so as to prevent the connecting rod from getting stuck between the hexagonal shaft 12 and the sleeve portion 3 when it enters the sleeve portion 3. The hexagonal shaft 12 is located at the center of the sleeve portion 3.

[0028] One end of the sleeve portion 3 extends to the end of the hand-cranked window opener housing 14. In this way, the operator can directly see the sleeve portion 3 through the opening of the hand-cranked window opener housing, so as to align the connecting rod of the right-angle deflector with the sleeve portion 3 and improve the insertion efficiency. If the sleeve portion 3 cannot be seen, there may be deviation when inserting the connecting rod, which will affect the work efficiency.

[0029] Furthermore, the sleeve portion 3 has an opening facing the embedded portion 1, giving it a C-shaped cross-section, and the upper end of the opening of the sleeve portion 3 is connected to the inclined side. The opening in the sleeve portion 3 saves raw materials and reduces manufacturing costs.

[0030] Preferably, the embedding part 1, the connecting part 2, and the sleeve part 3 are integrally formed. The embedding part 1, the connecting part 2, and the sleeve part 3 are all made of nylon and are extruded by a mold.

[0031] like Figure 5 As shown, the hand-cranked window opener includes a housing 14, a chain box 11, a mechanism 13, and a right-angle deflector 15. When the window opener is working, the right-angle deflector 15 transmits the hand-cranking power to the mechanism 13, which then moves the chain inside the chain box 11 to open or close the window. When installing the window opener, the housing 14 is first fixed to the window, and then the right-angle deflector 15 is connected. Because the right-angle deflector 15 is far from the housing 14, it is difficult to align the connecting rod 16 with the hexagonal shaft 12 located inside the housing 14 during connection, resulting in low assembly efficiency. Therefore, this invention provides a guide sleeve to facilitate connection.

[0032] When assembling the hand-cranked window opener, after fixing the guide sleeve to the chain box 11 of the hand-cranked window opener, cover it with the window opener housing 14. Then fix the housing 14 together with the internal structure to the window. Next, assemble the right-angle deflector 15 so that the connecting rod 16 of the right-angle deflector 15 is aligned with the connecting hexagonal shaft 12. With the cooperation of the guide sleeve, the insertion connection between the connecting rod 16 and the hexagonal shaft 16 is quickly completed.

[0033] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
