Description

Technical Field

[0001] The utility model relates to the technical field of simple doors and windows, in particular to a simple door and window hand pinching prevention device. Background Art

[0002] When using doors and windows, if they are frequently opened and closed, public safety needs to be considered, especially for children. If you are not careful when opening and closing them, it is easy to pinch the children's hands and cause safety accidents. Utility Model Content

[0003] The utility model aims to provide a simple door and window anti-pinch device to solve the door and window pinching problem mentioned in the background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A simple door and window anti-pinch device comprises an arc clamp, a clamping head is arranged at the end of the arc clamp, screw rods are symmetrically arranged on the inner side of the arc clamp, and internal threaded pipes are installed on the threaded sleeves on the two screw rods.

[0006] As a further description of the above technical solution:

[0007] The screw is arranged parallel to the opening of the arc clamp.

[0008] As a further description of the above technical solution:

[0009] The screw rod is arranged at the axis position of the circle where the arc clamp is located.

[0010] As a further description of the above technical solution:

[0011] There is a gap between the screws.

[0012] As a further description of the above technical solution:

[0013] The internal threaded tube is symmetrically provided with internal threads which are threadably connected to the screw rod.

[0014] As a further description of the above technical solution:

[0015] The outer side of the internal threaded tube is in the shape of a regular polygon.

[0016] Compared with the prior art, the utility model provides a simple door and window anti-pinch hand device, which has the following beneficial effects:

[0017] 1. In the utility model, by installing the device on the side of the simple door and window, a gap can be created when closing, so that it is safer for children to use;

[0018] 2. In the utility model, the clamp is tightened and loosened by rotating the internal threaded tube, without using glue, easy to install, and no traces left when disassembled. Moreover, the arc clamp body is arc-shaped without sharp corners, so it is very safe to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 2 The utility model provides a simple door and window anti-pinch device, including an arc clamp 1, a clamp head 2 is provided at the end of the arc clamp 1, screw rods 3 are symmetrically arranged on the inner side of the arc clamp 1, and internal threaded tubes 4 are installed on the threaded sleeves of the two screw rods 3.

[0026] Specifically, Figure 1 As shown, the screw rod 3 is arranged parallel to the opening of the arc clamp 1, and the screw rod 3 is arranged at the axial position of the circle where the arc clamp 1 is located. This position shortens the opening of the arc clamp 1 and is convenient.

[0027] Specifically, Figure 2 As shown, there is a gap between the screw rods 3 to reserve moving space for pulling.

[0028] Specifically, the internal threaded tube 4 is symmetrically provided with internal threads threadedly connected to the screw rod 3 , and the external side of the internal threaded tube 4 is a regular polygon, which can rotate without slipping and can synchronously adjust the screw rod 3 to move closer or farther away.

[0029] Working principle:

[0030] The arc clamp 1 is clamped on the side of the door and window, and the clamp head 2 is clamped on the two side surfaces of the door and window. Then the internal threaded tube 4 is rotated, and the two screws 3 are pulled inward. The two clamp heads 2 are tightened and pressed on the door and window. When the door and window are closed, the arc clamp 1 can play a role of limiting, leaving a gap when the door and window are closed, which is particularly suitable for use in public places.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
