Description

TECHNICAL FIELD

[0001] The utility model relates to door and window components field, concretely relates to a positioning type push-pull handle. BACKGROUND

[0002] The existing handle includes a shell provided with a shaft hole and a rotating shaft provided in the shaft hole. One end of the rotating shaft is connected with a knob, and the other end is connected with a lock tongue mechanism. In this way, the lock tongue mechanism is driven to move by rotating the knob, so that the door and window are opened or closed. However, the current handle has the following disadvantages: due to process limitations, the existing parts have large gaps, and the rotating shaft is easy to move, which not only makes the operation feel loose when rotating the knob, affecting the use experience. Moreover, when multiple windows are installed on one wall, the large gap between the parts may cause the knob to loosen, so the knob is easy to shift position under the influence of external force or vibration, so that the knobs of each window no longer point in the same direction, thereby affecting the overall aesthetics.

[0021] The technical solutions in the embodiments of the present application will be apparently and completely described in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without any creative labor fall within the protection scope of the present application.

[0022] Please refer to Figure 1 and Figure 5 , the present application is a positioning type push-pull handle, which comprises a shell 10 and a knob 11. The shell 10 has a cavity 101 inside. A hole 102 is opened on the end face of the shell 10 and communicates with the cavity 101. A connecting part 12 is connected to the knob 11 and extends into the cavity 101 from the hole 102. In the present embodiment, the connecting part 12 is in cylindrical structure.

[0023] In combination with Figure 2 and Figure 3 , the present application further comprises a stop structure 20 for preventing the knob 11 from rotating. The stop structure comprises two spring sheets 21 and a positioning block 22. Two insertion slots 26 are respectively arranged on the upper and lower sides of the hole 102 in the cavity 101. The two ends of the two spring sheets 21 are respectively inserted into the corresponding insertion slots 26. In addition, a recess 25 is arranged in the cavity, and a pressing plate 24 is fixed in the recess 25 and presses one end of the two spring sheets 21. The two ends of the pressing plate 24 are fixed in the cavity by screws. The positioning block 22 is connected to the front side of the connecting part 12 and rotates with the knob 11. The positioning block 22 has four clamping surfaces 221. The two spring sheets 21 are symmetrically arranged on the two sides of the positioning block 22, and the middle parts thereof clamp the clamping surfaces 221 of the positioning block 22.

[0024] As shown in Figure 3 and Figure 5 , in the present embodiment, the positioning block 22 is in square structure, and the clamping surface of the positioning block 22 is a plane. By using the structure, the plane contact can provide stable clamping effect, and the plane processing is relatively easy and has low manufacturing cost.

[0025] In the embodiment, the two adjacent clamped surfaces 221 are connected by the arc surface 222. With the structure, when the positioning block rotates, the friction and wear between the positioning block and the spring sheet can be reduced, and the rotation of the positioning block between the two spring sheets is smooth. Thus, when the knob 11 rotates, the positioning block 22 rotates, the distance between the point where the positioning block contacts the spring sheet and the rotation center becomes longer, and the resistance becomes larger. When the arc surface is reached, the resistance is the largest. When the resistance is overcome, the distance between the point where the positioning block contacts the spring sheet and the rotation center starts to become smaller, and the spring sheet pushes the clamped surface of the positioning block to accelerate the promotion of the positioning block to be vertical or horizontal, thereby causing the knob 11 to produce a jerk when rotating.

[0026] The first rotating shaft hole 223 is arranged in the positioning block 22. The first rotating shaft hole 223 is rectangular in cross section. The second rotating shaft hole 224 is arranged in the connecting part 12 and communicates with the first rotating shaft hole 223. The first rotating shaft hole 223 and the second rotating shaft hole 224 are coaxially arranged. The rotating shaft 14 is arranged in the first rotating shaft hole 223 and the second rotating shaft hole 224. The shape of the rotating shaft 14 is matched with the first rotating shaft hole 223. The front side end of the rotating shaft 14 extends out of the first rotating shaft hole.

[0027] As shown in Figure 5 the embodiment, the knob 11, the connecting part 12 and the positioning block 22 are integrally formed. The structure is convenient for assembly.

[0028] As shown in Figure 1 the handle 13 is connected to the shell 10. Three through holes 17 are arranged on the shell. During assembly, the shell is fixed on the door and window by using bolts passing through the through holes 17.

[0029] As shown in Figure 4 the first gasket 15 is arranged in the cavity, and the second gasket 16 is arranged outside the cavity. The snap spring 122 is arranged on the front side of the first gasket 15. With the above structure, the tightness and stability of the connection can be enhanced.

[0030] In summary, in the utility model, the two spring sheets are symmetrically arranged on both sides of the positioning block, and clamp the clamped surface of the positioning block, so that the knob can be kept stable when it is not actively rotated, and will not rotate due to external force or vibration. Secondly, when multiple sashes are installed, all the knobs can be rotated to point in the same direction, improving the overall appearance, and the operation of the knob is more comfortable.

[0031] The above has carried out the detailed description to one embodiment of the utility model, but the content described is only the preferred embodiment of the utility model, cannot be considered for limiting the implementation scope of the utility model. All equal changes and improvements etc. that are made in the utility model application scope should still belong to the patent coverage scope of the utility model.
