Description

Technical Field

[0001] The utility model relates to the field of locks, in particular to a door and window lock handle structure. Background Art

[0002] In daily life, in order to make it easier to lock and unlock doors and windows, additional handle structures are installed on door and window locks. Existing door and window lock handle structures generally consist of a handle base body and a limiting component within the handle base body. Common handle base bodies are long, sleeve-shaped. In order to better and more stably install the limiting component within the handle base, a corresponding mounting block is machined within the handle base. When the mounting block is installed within the handle base, its edge needs to fit against the inner side wall of the sleeve-shaped handle base. This ensures that the mounting block used to install the limiting component will not rotate relative to the handle base during the user's rotation, thereby ensuring the stability of the entire structure. However, in door and window lock handle structures of different patterns and specifications, mounting blocks of corresponding patterns and specifications need to be machined. The mounting blocks have a relatively complex appearance and high processing costs. In particular, the mounting blocks within some large-sized handle bases require a large amount of material to prepare. The mounting blocks within handle bases of different specifications are also not universal, and their adaptability is limited.

[0003] Therefore, the existing door and window lock handle structure has the problems of complex mounting block shape, high production cost and small application range. Utility Model Content

[0004] The purpose of the utility model is to provide a door and window lock handle structure. The utility model can not only simplify the appearance of the mounting block, but also has the advantages of low production cost and wide application range of the mounting block.

[0005] The technical solution of the utility model: a door and window lock handle structure, including a handle seat with an edge bent inwardly to form a shell shape, and a cavity is formed on the inner side of the handle seat; a drive shaft through hole is provided in the cavity, and raised limit shafts are connected to the upper and lower sides corresponding to the drive shaft through hole in the cavity, and the two limit shafts and the drive shaft through hole are located on the same straight line; a mounting block for installing a limit component is provided in the cavity, and a through hole of the same specification as the drive shaft through hole is provided in the middle of the mounting block, and slide grooves are provided on the upper and lower sides corresponding to the through hole of the mounting block, the two slide grooves and the through hole are located on the same straight line, and the width of the two slide grooves is the same as the diameter of the limit shaft; a drive shaft passing through the through hole is connected to the drive shaft through the through hole, and a handle is sleeved on one end of the drive shaft corresponding to the outer side of the handle seat, and the other end of the drive shaft is connected to a drive rod for driving the lock to open and close.

[0006] In the aforementioned door and window lock handle structure, a mounting groove is provided on the mounting block, and spring leaves are provided on both sides of the mounting groove corresponding to the drive shaft, and the upper and lower ends of each spring leaf are limited and clamped on the mounting groove; a rectangular block is provided on the driving shaft at a position corresponding to the position between the two spring leaves, and the length and width of the rectangular block are both greater than the distance between the two spring leaves.

[0007] In the aforementioned door and window lock handle structure, the four corners of the rectangular block are all provided with rounded corners.

[0008] In the aforementioned door and window lock handle structure, a chuck is provided on the drive shaft at the end surface corresponding to the inner side of the handle seat. The chuck is arranged close to the rectangular block, and the two sides of the chuck block the middle part of the two spring leaves to limit the position.

[0009] In the aforementioned door and window lock handle structure, a square mounting hole and a circular mounting hole that are mutually connected and distributed inside and outside are provided at the axis center of the drive shaft. The square mounting hole is arranged in cooperation with the drive rod, and a screw fixedly connected to the handle is provided in the circular mounting hole.

[0010] In the aforementioned door and window lock handle structure, the portion of the drive shaft for sleeve-mounting the handle is in the shape of a regular quadrangular prism.

[0011] In the aforementioned door and window lock handle structure, a limiting ring is sleeved on the driving shaft, and there is an interference fit between the limiting ring and the driving shaft. The limiting ring is tightly arranged on the outer surface of the handle seat.

[0012] In the aforementioned door and window lock handle structure, screw mounting holes are provided at both the upper and lower ends of the handle base.

[0013] Compared with the prior art, the utility model provides two linearly distributed limit shafts and a drive shaft through hole in the cavity on the inner side of the handle seat, and provides two linearly distributed slide grooves and a through hole on the mounting block for installing the limit component; it is only necessary to slide the two slide grooves on the mounting block onto the two limit shafts respectively, and slide the mounting block relatively so that the through hole is aligned with the drive shaft through hole to install the drive shaft for connecting the handle and the drive rod, and stable installation can be achieved without making the edge of the mounting block close to the inner wall of the cavity, and the mounting block cannot rotate relative to the handle seat. It is only necessary to prepare a mounting block of uniform specifications to be applicable to handle seats of various patterns and specifications, which simplifies the appearance of the mounting block, reduces its production cost, and improves its scope of application.

[0014] In addition, the mounting block in the utility model is provided with a mounting groove for installing a limiting component, wherein the limiting component is a spring sheet distributed on both sides of the drive shaft and a rectangular block located on the drive shaft. Since the length and width of the rectangular block are both greater than the distance between the two spring sheets, the two spring sheets can better clamp the rectangular block and limit it, so that when the handle is rotated to open or close the lock, the handle can be automatically limited and remain stable; the four corners of the rectangular block are all provided with chamfered corners, and the drive shaft rotates smoothly.

[0015] The chuck on the inner end face of the drive shaft is tightly attached to the rectangular block, and the two sides of the chuck block the middle of the two spring leaves, which can ensure that the spring leaves on both sides can always be restricted to the two sides of the rectangular block, reducing the mechanical failure rate.

[0016] The circular mounting hole at the center of the drive shaft can be used to set screws to stably fix the handle on the drive shaft, and the connection part between the drive shaft and the handle is in the shape of a regular square prism, so that the rotation of the handle can better drive the rotation of the drive shaft; the square mounting hole at the center of the drive shaft can cooperate with the regular square prism-shaped drive rod, so that after the drive shaft rotates, it can also stably drive the rotation of the drive rod, thereby more stably controlling the opening and closing of the lock.

[0017] The limiting ring of the interference sleeve on the drive shaft is tightly attached to the outer surface of the handle seat, so that the mounting block and the drive shaft can be stably connected to the handle seat, the internal parts are not easily deviated, and the stability is high.

[0018] Therefore, the utility model can not only simplify the appearance of the mounting block, but also has the advantages of low production cost of the mounting block, wide application range of the mounting block, good smoothness of use, low failure rate and high structural stability.
