SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a safe fork handle of opening can prevent effectively that children from opening door and window under the condition of not protecting.
In order to achieve the above object, the utility model adopts the following technical scheme:
a safety opening shifting fork type handle comprises a handle, a handle seat, a boss shaft and a limiting seat, wherein the limiting seat is fixed on the inner side of the handle seat, at least one clamping groove is formed in the limiting seat, the handle is rotatably arranged on the outer side of the handle seat, the boss shaft penetrates through a center hole of the handle seat and is fixedly connected with the inner side of the handle, at least one clamping boss is arranged at one end, away from the handle, of the boss shaft, a compression spring is arranged between the inner side of the handle and the handle seat, one end of the compression spring presses towards the handle, and the other end of the compression spring presses towards the end face of a shaft hole in the outer side of the handle seat; when the safety opening shifting fork type handle is fixed on a door and window, the compression spring applies a force vertical to the handle seat to push the handle outwards, the boss connected with the handle moves towards the outer side, the clamping boss on the boss shaft is pressed into the clamping groove on the limiting seat, and the handle cannot rotate at the moment, so that the door and window cannot be opened through direct rotation; only an inward force is applied to the handle to overcome the elasticity of the compression spring, the clamping boss on the boss shaft is pushed out of the clamping groove on the limiting seat, and at the moment, the handle can rotate to open the door and window.
One end of the compression spring is pressed against the inner side of the handle, and the other end of the compression spring is pressed against the end surface of the shaft hole in the handle seat.
The screens boss sets up the boss is epaxial, and the shape is the cuboid, and the fillet has been done to the screens boss and has been handled.
The clamping groove is arranged on the limiting seat, and the position of the clamping groove corresponds to that of the clamping boss.
The utility model has the advantages that: the handle is rotatably arranged at the outer side of the handle seat, the boss shaft passes through the central hole of the handle seat and is fixedly connected with the inner side of the handle, a compression spring is arranged between the inner side of the handle and the handle seat and provides outward thrust for the handle, the clamping boss on the boss shaft is pressed into the clamping groove on the limiting seat, the handle cannot rotate, and the handle cannot be rotated to open a door or window; only when pressure is applied to the handle seat at the handle to overcome the elasticity of the compression spring, the clamping boss on the boss shaft is separated from the clamping groove on the limiting seat, and then the door and the window can be opened by rotating the handle; the door and window can be effectively prevented from being opened by children under the condition of no protection, and a good protection effect is achieved.

Detailed Description
The invention is further explained below with reference to the drawings:
the safety opening shifting fork type handle as shown in fig. 1 to 4 comprises a handle 1, a compression spring 2, a handle seat 5, a boss shaft 7 and a limiting seat 6, wherein the limiting seat 6 is fixed on the handle seat 5, and the boss shaft 7 passes through the handle seat 5, an upper cover plate 4, a shaft sleeve 3 and the compression spring 2 and is fixedly connected with the inner side of the handle 1; the upper cover plate 4 is fixed on the outer side of the handle seat 5, the shaft sleeve 3 is sleeved on the outer end shaft surface of the handle seat 5, and the handle 1 is fixedly connected with the outer end surface of the shaft sleeve 3.
One end of the compression spring 2 presses towards the inner side of the handle 1, and the other end of the compression spring presses towards the end surface of the shaft hole of the handle seat 5; under the conventional state, compression spring 2 will handle 1 drives outwards the screens boss 10 on the boss axle 7 is absorbed in the screens recess 11 on the spacing seat 6 for can't rotate handle 1, children can't rotate handle 1 this moment and directly open door and window.
When right handle 1 is inside to exert pressure will screens boss 10 on the boss axle 7 breaks away from screens recess 11 on the spacing seat 6, handle 1 rotates, drives boss axle 7 and rotates, and boss axle 7 drives gear shaft 8 and rotates, and the gear drives the rack motion of shift fork 9 on the gear shaft 8, opens door and window.
The clamping groove 11 is arranged on the limiting seat, and the position of the clamping groove corresponds to that of the clamping boss 10.
The handle is rotatably arranged at the outer side of the handle seat, the boss shaft passes through the central hole of the handle seat and is fixedly connected with the inner side of the handle, a compression spring is arranged between the inner side of the handle and the handle seat and provides outward thrust for the handle, the clamping boss on the boss shaft is pressed into the clamping groove on the limiting seat, the handle cannot rotate, and the handle cannot be rotated to open a door or window; only when pressure is applied to the handle seat at the handle to overcome the elasticity of the compression spring, the clamping boss on the boss shaft is separated from the clamping groove on the limiting seat, and then the door and the window can be opened by rotating the handle; the door and window can be effectively prevented from being opened by children under the condition of no protection, and a good protection effect is achieved.
