Technical Field
[0001] This utility model relates to the field of handle technology, specifically to a child safety insurance handle. Background Technology
[0002] Handles are devices installed on door and window sashes, serving both to open and secure them after closing. They are mostly made of materials such as aluminum alloy, copper, stainless steel, plexiglass, and plastic. They come in various forms and sizes. In addition to meeting the requirements of comfortable handling and reasonable force distribution, they also have a decorative effect; therefore, the materials and shapes are selected from ready-made products or custom-designed according to the architectural design requirements.
[0003] A known authorized patent application with application number CN202222291745.0 discloses a background technology that addresses the problem that "doors and windows can be unlocked by rotating the handle, which can easily lead to children accidentally rotating the handle and causing the doors and windows to open, posing a risk of children falling out of the doors and windows and threatening their personal safety." The proposed solution is to include a base and a handle on one side of the base. A lock sleeve runs through the base and connects to the handle, allowing the handle and lock sleeve to rotate relative to the base. A safety lock assembly is installed on the inner side of one end of the base, which can unlock or lock the handle by engaging with the lock sleeve.
[0004] However, the following problems were found in the implementation of the relevant technology: although the provided technology achieves the effect of unlocking or locking the handle, its structure is relatively complex and its safety structure is poorly concealed. Children can easily discover or accidentally touch the button to unlock the handle, which reduces the effectiveness of the handle and the safety of doors and windows. Utility Model Content
[0005] This utility model proposes a child safety safety handle, which solves the problem that the existing technology has a complex structure and poor concealment, making it easy for children to notice or accidentally touch the button to unlock the handle, thus reducing the effectiveness of the handle and the safety of doors and windows.
[0006] The technical solution of this utility model is as follows: A child safety handle, comprising: a base, wherein an installation groove is provided on one side of the base;
[0007] A connector is provided in the mounting groove and penetrates the base, and the connector is limited by a snap-fit mechanism provided in the mounting groove;
[0008] A handle attached to one end of the connector;
[0009] A rotating shell is rotatably connected to the surface of the connector and located on one side of the base, the rotating shell and the base having the same shape and size;
[0010] An elastic locking mechanism is provided in the base for locking and unlocking the connector, and the surface of the connector is provided with a plurality of pin holes that cooperate with the elastic locking mechanism.
[0011] And a triggering mechanism located within the rotating housing for moving the elastic locking mechanism to extend into or out of the pin hole groove.
[0012] Preferably, the elastic locking mechanism includes an inner groove formed in the base, a locking pin that slides through and is slidably connected in the inner groove, a limiting ring fixedly connected to the surface of the locking pin, and a spring sleeved on the surface of the locking pin and connected at both ends to the limiting ring and the inner groove respectively.
[0013] The locking pin and the pin hole groove are inserted together, and one end of the locking pin is conical.
[0014] Preferably, the triggering mechanism includes a gasket fixedly installed on the inner wall of the rotating housing, and a locking hole formed on the gasket and engaged with the locking pin.
[0015] Preferably, the locking mechanism includes a mounting base disposed inside the mounting groove of the base, a limiting component disposed inside the mounting base, and a plurality of arc-shaped grooves formed on the surface of the connector and cooperating with the limiting component. The connector is located inside the mounting base, and the mounting base has a through hole corresponding to the locking pin.
[0016] The limiting component includes a second spring symmetrically fixedly installed between the inner walls of the slots on both sides of the mounting base, and a ball fixedly connected to one end of the second spring, wherein the ball engages with the arc-shaped slot.
[0017] The working principle and beneficial effects of this utility model are as follows:
[0018] After the handle is turned to close the door or window, the rotating shell and the washer are rotated 180 degrees, causing the washer to press the locking pin and separate it from the locking hole. This, combined with the limiting ring pressing the spring, locks the connecting piece by inserting the locking pin and the pin hole groove, preventing the handle from turning. To unlock, the rotating shell is rotated again to align the locking pin and the locking hole. The spring then causes the locking pin to separate from the pin hole groove and insert into the locking hole. This achieves the locking or unlocking of the handle. The overall structure is relatively simple, and the rotating shell can be integrated with the base after rotation for concealment, making it difficult to notice or accidentally touch, thus preventing children from accidentally disengaging it. This effectively improves the usability of the handle and the safety of the doors and windows. Attached Figure Description

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0030] Example
[0031] Please see Figure 1 - Figure 8 The present invention provides a child safety safety handle, comprising: a base 1, wherein a mounting groove is provided on one side of the base 1;
[0032] A connector 2 is provided in the mounting groove and passes through the base 1. The connector 2 is limited by a snap-fit mechanism provided in the mounting groove.
[0033] Handle 3 is connected to one end of connector 2;
[0034] Rotary shell 4 is rotatably connected to the surface of connector 2 and located on one side of base 1. Rotary shell 4 and base 1 have the same shape and size.
[0035] An elastic locking mechanism is provided in the base 1 for locking and unlocking the connector 2. The surface of the connector 2 is provided with a plurality of pin hole grooves 5 that cooperate with the elastic locking mechanism.
[0036] And a triggering mechanism located inside the rotating housing 4 for moving the elastic locking mechanism to extend into or out of the pin hole groove 5.
[0037] The elastic locking mechanism includes an inner groove 6 formed in the base 1, a locking pin 7 that slides through the inner groove 6, a limiting ring 8 fixedly connected to the surface of the locking pin 7, and a spring 9 sleeved on the surface of the locking pin 7 and connected at both ends to the limiting ring 8 and the inner groove 6 respectively.
[0038] The locking pin 7 and the pin hole groove 5 are inserted into each other, and one end of the locking pin 7 is conical.
[0039] The triggering mechanism includes a gasket 10 fixedly installed on the inner wall of the rotating housing 4, and a locking hole 11 opened on the gasket 10 and engaged with the locking pin 7.
[0040] The technical solution provided in this embodiment is as follows: In use, the handle 3 is rotated, and the connecting piece 2 is rotated synchronously through the handle 3, thereby facilitating the opening or closing of doors and windows. After the doors and windows are closed, the rotating shell 4 is rotated 180 degrees, which in turn rotates the gasket 10 180 degrees. Since the conical end of the locking pin 7 is engaged with the locking hole 11, the gasket 10 can press the locking pin 7 to move in the inner groove 6 under the action of the conical surface during the rotation of the gasket 10. At the same time, the locking pin 7 and the locking hole 11 are separated. When the locking pin 7 moves, it synchronously drives the limiting ring 8 to move and presses the spring 9. At the same time, the locking pin 7 passes through the snap-fit mechanism and the corresponding part on the connecting piece 2. When the pin hole groove 5 is inserted, the connector 2 can be fixed and locked, preventing the handle 3 from rotating. To unlock, the rotating shell 4 is rotated 180 degrees again, aligning the locking pin 7 with the locking hole 11. The spring 9 then drives the locking pin 7 to reset and separate from the pin hole groove 5, inserting it into the locking hole 11, allowing the handle 3 to rotate. Thus, the handle 3 can be locked or unlocked. The overall structure is relatively simple. Since the rotating shell 4 and the base 1 have the same shape and size, the rotating shell 4 can be integrated with the base 1 after rotation, making it difficult to notice or accidentally touch, thus preventing children from accidentally unlocking it. This effectively improves the usability of the handle 3 and the safety of doors and windows.
[0041] Furthermore, the locking mechanism includes a mounting base 12 located inside the mounting groove of the base 1, a limiting component located inside the mounting base 12, and a plurality of arc-shaped grooves 15 formed on the surface of the connector 2 and cooperating with the limiting component. The connector 2 is located inside the mounting base 12, and the mounting base 12 has a through hole 16 corresponding to the locking pin 7. The through hole 16 facilitates the locking pin 7 to pass through the mounting base 12 to lock the connector 2.
[0042] The limiting component includes a second spring 13 symmetrically fixedly installed between the inner walls of the slots on both sides of the mounting base 12, and a ball 14 fixedly connected to one end of the second spring 13. The ball 14 and the arc-shaped groove 15 are engaged.
[0043] Specifically, during the process of opening or closing the door or window by rotating the handle 3, the handle 3 can synchronously drive the connecting piece 2 to rotate. At this time, the rotating connecting piece 2 cooperates with the arc groove 15 to squeeze the ball 14 and compress the spring 13, so that the ball 14 separates from the corresponding arc groove 15. After rotating to a certain angle and stopping, under the elastic force of the spring 13, the ball 14 can be driven to reset. At the same time, accompanied by a slight clicking sound, the ball 14 can be engaged with the corresponding arc groove 15, so as to achieve the function of limiting the connecting piece 2 and ensuring the rotational stability of the connecting piece 2.
[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
