Description

Inner casement leaf lock shift fork handle

technical field

The utility model relates to the technical field of door and window components, in particular to a fork-type handle structure with a lock.

Background technique

Doors and windows are a common wing structure on buildings, usually used as room access passages and ventilation and lighting openings of buildings. With the development of modern building technology and the improvement of user requirements, people continue to improve the structure of doors and windows. The handle is an essential and important component on doors and windows. The handles used in modern buildings usually include a handle seat installed on the window sash and a rotatable handle installed on the handle seat. Due to the restrictions involved in the structure, the hand seat has a huge structure, which affects the appearance. For this reason, those skilled in the art have carried out many improvements to the handle structure of doors and windows. For example, the Chinese patent announcement number is CN201339344Y, and the name is a handle, which includes a handle and a handle seat. The handle includes a handle seat and a handle extending from the handle seat. The shape of the handle seat matches the handle seat. The outer diameter of the handle base is slightly larger than the handle base and enough to be provided with a longitudinally extending accommodating hole on the handle base to accommodate the handle base, and the action member of the handle is arranged between the handle base and the handle base. The specification of this patent also discloses that the side wall of the accommodating hole is provided with a locking hole extending transversely through the hole wall. That is to say, the handle of this structure has only one fixed locking point when the sash is closed and locked, which brings a lot of inconvenience to the user. For this reason, on 2010.08.14, those skilled in the art proposed a new type of handle structure for casement bottom-hung windows, and its authorized announcement number is 201763052U. Compared with the traditional technology, there are certain advantages for locking in the direction. But, through several years of production, processing and popularization, there are still many shortcomings in the handle of this structure, as the following shortcomings are particularly prominent: 1. The structure is complicated, because each locking point relies on springs and steel balls to directly press against the handle. The groove is positioned. In order to balance the force, it is necessary to symmetrically set the combined structure of the spring and the steel ball on both sides of the handle. However, the small-diameter steel ball is embedded in the groove under the pressure of the spring. Without being bounced off, the workers need to be highly concentrated, the labor intensity of the workers is high, and the production efficiency is low; 2. Because the doors and windows need to be opened and closed frequently, the springs are prone to failure after a certain period of time, and it is difficult to replace parts at this time. It is the replacement of the whole handle, which causes a waste of resources and increases the cost of the user.

Contents of the invention

When the lock core is installed, the clamping retaining ring can be clamped on the card. Bits without shifting up and down. The side of the lock cylinder is provided with a positioning projection, and the inner wall of the lock hole where the handle is installed with the lock cylinder is correspondingly provided with a positioning groove that matches the concave and convex of the positioning projection. When the lock cylinder is installed, the matching between the positioning projection and the positioning groove The lock core can be prevented from rotating relative to the lock hole.

A transmission gear 3 is installed in the handle seat 2, and a shift fork 4 is arranged on the handle seat 2. The handle 1 drives the shift fork 4 through the connection of the transmission gear 3. The bottom of the handle seat 2 is provided with a gasket 5, and the gasket 5 is provided with Slotted hole 6 for allowing the shift fork to pass through. The transmission gear 3 is sheathed with an annular elastic member 7, which is generally made of plastic with a certain degree of elasticity; a sheath 8 that is press-fitted with it is arranged above the annular elastic member, and the sheath 8 is fixed on the handle 1 Between the handle base 2 and along the circumferential direction of the annular elastic member 7, several contacts 7-1 are provided which are concave-convexly matched with the handle base. Each pair of adjacent two contacts in the annular elastic member 7 are correspondingly formed with the same angle between the centers of the circles. In this embodiment, the locking points arranged on the handle base are evenly distributed in a circle, and the number is 4, and the number of corresponding contacts is also 4. After the 4 contacts are evenly distributed in a circle, it is also That is to say, the angle between the center of the circle corresponding to every two contacts is 90 degrees, and the handle can be locked by the lock cylinder every 90 degrees of rotation. The annular elastic member 7 has a wave-shaped structure, and is provided with a lower contact in contact with the transmission gear. The lower contact is located at the trough of the wave-shaped structure, and there is an upper contact in contact with the sheath at the peak. The upper contact is provided with an upward protruding bump 1 7-11, and the lower contact is provided with a downward protruding bump 2 7-12.

The transmission gear 3 includes a lower transmission tooth 3-1 and an upper positioning base 3-2 corresponding to the annular elastic member. The annular elastic member is sleeved on the positioning base. Moving gear 4-1. The handle 1 includes a handle part 1-1 and a shaft part 1-2 fixedly connected with the handle part. The handle base 2 is provided with a cavity 10 for accommodating the sheath 8 and the transmission gear 3 respectively, and the shaft parts are successively Through the cavity for accommodating the sheath and the transmission gear, there is a fixing screw 9 in the middle of the transmission gear to fasten it on the shaft part 1-2 of the handle.

When using this kind of side-opening bottom-hung window, first make the lock cylinder in the open state, after turning the handle, the handle drives the transmission gear to rotate, and the transmission gear drives the shift fork to move, and the shift fork moves the linkage mechanism on the sash to Make the sash open flat or hang down.

The biggest improvement of the utility model is that the traditional steel ball and spring combination structure is replaced by a simple and easy-to-process annular elastic part, which is easy to install, can greatly improve production efficiency, and reduce labor intensity of workers.

The above is only the preferred embodiment of the utility model, it should be pointed out that, for those of ordinary skill in the art, without departing from the inventive concept of the utility model, some deformations and improvements can also be made. Belong to the protection scope of the utility model.
