Description

Technical Field

[0001] The utility model relates to the technical field of door and window handles, and in particular to a handle structure that is locked up and down. Background Art

[0002] Doors and windows are the most common structures in buildings, usually serving as entrances and exits to rooms and ventilation and lighting openings. With the development of modern architecture and the increasing needs of users, the structure of doors and windows has been continuously improved. Among them, handles, as essential components of doors and windows, are installed on door and window panels to realize the opening and closing of door and window panels.

[0003] This type of door and window handle can unlock the door and window by rotating the handle part, and it is easy for children to accidentally rotate the handle part and cause the door and window to open, thereby posing a risk of children falling out of the door and window, thereby threatening the personal safety of children. There are certain safety hazards, and children often open the doors and windows of the home without permission and climb out of the windows, causing safety accidents. Therefore, it is necessary to improve the safety performance of the door and window handles.

[0004] A Chinese patent with application number 202222291745.0 discloses a child handle, in which the safety lock assembly unlocks or locks the handle by limiting the position with the lock sleeve, and the safety lock assembly adopts a ratchet assembly to cooperate with a button, so that when the button is pressed, the pawl pushes the ratchet to rotate the dial wheel, and the limiting ball slides along the arc groove to the arc top groove, so that the ball abuts against the lock groove of the lock sleeve through the arc top groove, thereby locking the handle, which can effectively reduce the risk of children accidentally turning the handle and causing doors and windows to open.

[0005] Although the above patent solves the problem of preventing door and window handles from being opened by children, the safety lock assembly of the handle has a complex structure. Due to the size of the handle itself, the complex structure is smaller in size, which increases the difficulty of producing and installing parts. At the same time, the complex structure has a higher failure rate, and the stability and service life of the handle are reduced. Utility Model Content

[0006] The utility model aims to provide a handle structure that can be locked up and down, so as to solve the technical problems that the existing handle structure is complicated and the stability and service life of the handle are reduced.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A handle structure for locking up and down, comprising an outer base, one side of the outer base is connected to an outer cover plate, and the other side of the outer base is connected to an inner cover plate; a lock core component is slidably installed on the inner side of the outer base, a driving core for driving the lock core component to slide up and down is rotatably installed in the outer base, one end of the driving core extends out of the outer cover plate and is fixedly connected to a handle; two groups of symmetrically distributed driving bead grooves are provided on the driving core, and the lock core component comprises a lock core slide frame slidably arranged in the outer base, a steel ball groove is provided on the inner side of the lock core slide frame, and a limiting steel ball is connected between the steel ball groove and the driving bead groove.

[0009] As a further solution of the utility model: the handle structure has a locked state and an unlocked state.

[0011] As a further solution of the utility model: the outer base includes a base body, and lock core sliding grooves matching with the lock core member are arranged on both sides of the base body.

[0012] As a further solution of the utility model: the outer base is provided with a mounting column for mounting the inner cover plate on one side of the lock core groove, the outer base is provided with a limiting column for limiting the sliding position of the lock core member, and the limiting column is provided with two groups of limiting grooves along the sliding direction of the lock core member.

[0013] As a further solution of the utility model: the lock core slide is provided with an avoidance groove for avoiding the drive core, one end of the lock core slide is provided with an upper locking head matching with the lock core slide groove, and the other end of the lock core slide is provided with a lower guide head matching with the lock core slide groove.

[0014] As a further solution of the utility model: two groups of limit rods are arranged on the inner side of the lock core slide, and limit clamping blocks matching with the limit grooves are fixedly arranged on the limit rods.

[0015] Beneficial effects of the utility model:

[0016] The product is locked by forming a stuck state through the limiting steel ball, the steel ball groove on the lock core and the driving ball groove on the driving core. It belongs to a brand-new structure, a simple three-point physical structure, strong stability and extremely low cost.

[0017] The locking mechanism is composed of a stuck state formed by a limiting steel ball, a steel ball groove provided on the lock core, and a driving ball groove provided on the driving core. This can effectively prevent children from operating the handle to open doors and windows, thereby improving the safety performance of doors and windows. The locking mechanism has a simple structure and fewer matching parts, which reduces the complexity of the original structure. On the one hand, a simple structure has fewer failures, thereby increasing the service life of the handle. On the other hand, the simple structure is easy to process and assemble, saving the production cost of the handle.

[0018] The cooperation of the limit block and the limit groove plays a role in limiting the opening and closing position of the upper locking head, ensuring that the handle structure can remain stable in both the locked and unlocked states. The limit mechanism composed of the limit rod, the limit block and the limit groove has a simple structure, and the processing and assembly of the product are extremely convenient, effectively avoiding the complex structure of existing market products.
