The technical scheme for solving the technical problems is as follows: the utility model provides a domestic door anti-pinch device, includes door, door handle, pressure spring, rack connecting rod, gear, silica gel locating lever and connecting rod installation baffle, the door handle is installed on the door, it has the mounting groove to open on the door, and the rack connecting rod is placed in the mounting groove, and connecting rod installation baffle is fixed in the mounting groove outside, and the gear is installed on the door handle, and one section that the rack connecting rod is close to the door handle is provided with the tooth, and the tooth meshing on the wheel and the rack connecting rod, pressure spring are located between rack connecting rod top and the mounting groove top, and the silica gel locating lever passes through the screw thread and installs in rack connecting rod bottom, and when no external force was used, under pressure spring.
The connecting rod installation baffles are arranged in two numbers, and the two connecting rod installation baffles are installed on the outer side of the installation groove below the door handle at intervals.
The hand clamping prevention device is integrated with the door, and the gear is driven to rotate by rotating when the door is opened through the handle, so that the silica gel positioning rod is lifted, and the door can move freely. When the hand leaves the door handle, door handle automatic re-setting, silica gel locating lever contact ground, the door is fixed, reaches the purpose of preventing pressing from both sides the hand, can effectively prevent to close because of the inertia of door or external factors and press from both sides the condition emergence in hand. The invention has the following specific beneficial effects:
1. the invention does not need to change the internal structures of the existing door lock and the existing door handle, only needs to control the lifting and descending of the anti-pinch device by means of the rotation action of the door handle, does not damage the structure of the lock body, and is convenient to install.
2. The invention realizes the function of preventing hands from being clamped by using the friction force between the silica gel positioning rod positioned at the bottom of the door and the ground, and is simple and practical.
3. When the hand clamping prevention function is not needed, the silica gel positioning rod is lifted in an upward rotating mode to be separated from the ground, the hand clamping prevention positioning function can be removed, and the operation is very convenient.
The technical features of the hand-clipping prevention device for a home door of the present invention will be further described with reference to the accompanying drawings and embodiments.

In the figure: 1-door handle, 101-square bolt, 2-door lock panel, 3-door, 4-door frame, 5-pressure spring, 6-rack connecting rod, 61-tooth, 7-gear, 8-silica gel positioning rod, 9-connecting rod installation baffle and 10-ground.
Detailed Description
Example 1: the utility model provides a domestic door anti-pinch device, as shown in fig. 1-5, includes door 3, door handle 1, compression spring 5, rack connecting rod 6, gear 7, silica gel locating lever 8 and connecting rod installation baffle 9, and the door handle is installed on the door, it has the mounting groove of bar to open on the door 3, and rack connecting rod 6 places in the mounting groove, and connecting rod installation baffle 9 is fixed in the mounting groove outside, and connecting rod installation baffle 9 is spacing to rack connecting rod 6, and it has the tetragonal trough to open in the middle of the gear 7, and the tetragonal trough just can embolia the tetragonal bolt. The gear is installed on the square bolt 101 of door handle, and rack link is close to one section of door handle and inlays and be provided with a plurality of teeth 61, and gear 7 meshes with the tooth on the rack link 6, and pressure spring 5 is located between rack link 6 top and the mounting groove top, and pressure spring 5 upper end and mounting groove top contact promptly, and pressure spring 5 lower extreme and rack link 6 contact. Silica gel locating lever 8 passes through the screw thread and installs in 6 bottoms of rack connecting rod, and silica gel locating lever 8 is inside to be opened promptly has the internal thread, is connected with the external screw thread cooperation of 6 bottoms of rack connecting rod. When no external force is acted, the silica gel positioning rod compresses the ground under the pressure of the pressure spring.
In this embodiment, there are two connecting rod installing baffles 9, and the two connecting rod installing baffles are installed at the outer side of the installing groove below the door handle at intervals. As an alternative, the number of the connecting rod mounting baffles can be increased or decreased according to actual conditions.
The action process is as follows:
as shown in fig. 1 to 5, the door is closed, the door handle 1 is in a horizontal rest position, and the rack link 6 is pressed downward by the pressure spring 5. At this time, the silica gel positioning rod 8 in threaded connection with the bottom of the rack connecting rod 6 is in contact with the ground.
When opening the door, the rotating door handle 1 is pressed downwards, and the square bolt connected with the inside of the door handle 1 rotates along the axis at the same time to drive the lock tongue to pull back. The gear 7 is driven to rotate while the square bolt rotates along the axis, so that the rack connecting rod 6 is driven to move upwards, the silica gel positioning rod at the bottom of the rack connecting rod 6 is separated from the ground, and the door opening action is realized, as shown in fig. 6-8. The door handle 1 is in a pressing state in the door opening process, and when the door handle is placed at a proper position, the hand is released, and the door handle returns. At this moment, the gear 7 only has the pressure of the pressure spring 5 under the action of no external force, and continues to move downwards under the action of the pressure, the rack connecting rod 6 moves downwards, and the silica gel positioning rod 8 connected with the bottom of the rack connecting rod 6 is in contact with the ground. Under the effect of silica gel locating lever 8 and ground friction power, the door is motionless, also is difficult to promote to prevent the sudden closure of door and produce the tong.
When the hand-clamping prevention function is not needed to be realized, the door handle 1 is pressed down firstly, and the gear 7 drives the rack connecting rod 6 to move upwards. At this moment, the circular silica gel positioning rod 8 rotates along the center of the rack connecting rod 6, so that the circular silica gel positioning rod 8 moves upwards and is lifted. When the door handle return, silica gel locating lever and ground have separated, and the door will not play and prevent tong effect.
