Description

Technical Field

[0001] The utility model relates to the technical field of unlocking tools, in particular to a peephole unlocking tool for anti-theft doors. Background Art

[0002] The peephole unlocking tool for security doors is one of many unlocking tools. The specific unlocking method is: first extend the unlocking tool into the room through the peephole on the security door, and the part of the unlocking tool extending into the room touches the inner handle of the door lock, and then rotate the part of the unlocking tool extending out of the room to drive the part of the unlocking tool extending into the room to rotate the inner handle of the door lock, so as to open the security door without damaging the door lock. However, the above unlocking tool cannot be positioned quickly and accurately, and needs to be reciprocated to align the inner handle of the door lock many times, resulting in a long positioning time and too complicated operation steps, which greatly prolongs the unlocking time.

[0003] In order to solve the above technical problems, manufacturers have developed a variety of easy-to-operate anti-theft door cat's eye unlocking tools, such as the Chinese invention patent with patent number CN106437305B, entitled "A Type of Adjustable Anti-slip Anti-theft Door Cat's Eye Unlocking Tool". In this patent, the inner and outer buckles are set to more firmly grasp the inner handle of the door lock to prevent slipping and shorten the positioning time; however, the above anti-theft door cat's eye unlocking tool has a complex structure and cumbersome operation, and cannot quickly open the anti-theft door.

[0004] Therefore, how to design an anti-theft door peephole unlocking tool that is simple in structure, low in cost, easy to operate and can quickly open the door lock is a problem that technicians in this field urgently need to solve. Utility Model Content

[0005] The utility model provides a peephole unlocking tool for anti-theft doors, which solves the technical problems of the existing peephole unlocking tools for anti-theft doors, such as complex structure, cumbersome operation and long unlocking time.

[0006] The utility model solves the above technical problems with the following technical solutions: a peephole unlocking tool for anti-theft doors, comprising: an operating cylinder, a slide rod, a pressure rod for pressing and rotating the inner handle of the door lock, a spring and a bendable driving rod.

[0007] The operating cylinder includes a first cylinder body and a second cylinder body that are integrally formed and vertically arranged, and both the first cylinder body and the second cylinder body can be inserted into the cat's eye of the anti-theft door, and a long hole arranged along its axial direction is provided on the cylinder wall of the second cylinder body; the sliding rod slides in the second cylinder body; the pressure rod can movably penetrate into or out of the long hole and one end of the pressure rod is hinged to the end of the sliding rod away from the first cylinder body; one end of the spring is hinged to the rod wall of the sliding rod and the other end of the spring is hinged to the rod wall of the pressure rod; the pressure rod is arranged at an angle to the sliding rod in the natural state of the spring; the driving rod slides in the first cylinder body and the second cylinder body and the end thereof extending into the second cylinder body is fixed to the end of the sliding rod close to the first cylinder body, and the end thereof away from the second cylinder body extends out of the first cylinder body, so as to drive the sliding rod and the pressure rod to reciprocate along the axial direction of the second cylinder body while the driving rod slides.

[0008] The beneficial effects of the utility model are as follows: first, the pressure rod is rotated forcefully into the long hole and in a straight line with the sliding rod; then the second cylinder, the sliding rod, the pressure rod and the spring are extended into the room through the cat's eye. Since one end of the spring is hinged on the rod wall of the sliding rod and the other end is hinged on the rod wall of the pressure rod, at this time, the pressure rod will be arranged at an angle with the sliding rod as the spring returns to its initial state; finally, the driving rod is pushed and pulled to drive the sliding rod and the pressure rod to move back and forth along the axis of the second cylinder, so that the pressure rod can directly press and rotate the inner handle of the door lock, reduce positioning, and quickly open the anti-theft door; the above-mentioned anti-theft door cat's eye unlocking tool has a simple structure, low manufacturing cost, convenient operation, can quickly open the anti-theft door, and shortens the unlocking time.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the elongated hole passes through the free end of the second cylinder.

[0011] Furthermore, the pressure rod is arranged parallel to the first cylinder in the natural state of the spring.

[0012] A further beneficial effect of adopting the above method is that by arranging the pressure rod in parallel with the first cylinder, positioning can be reduced and the pressure can be directly pressed on the inner handle of the door lock, thereby improving the unlocking efficiency and shortening the unlocking time.

[0013] Furthermore, it also includes a first operating handle, which is axially provided with through holes penetrating through both ends thereof and is sleeved on the free end of the first cylinder.

[0014] Furthermore, it also includes a second operating handle, one end of which is fixed to one end of the driving rod extending out of the first cylinder, and the second operating handle can touch the first operating handle.

[0015] A further beneficial effect of the above is that the first operating handle and the second operating handle are installed, and the second operating handle is used to touch the first operating handle, so that the convenience of using the anti-theft door cat's eye unlocking tool can be improved.

[0016] Furthermore, it also includes a guide strip plate, which slides in the long hole along the length direction of the long hole and is fixed on the side wall of the sliding rod.

[0017] A further beneficial effect of the above method is that the guide strip is used to slide along the length direction of the long hole, and the guide strip is fixed on the slide bar to guide the moving direction of the slide bar.

[0018] Furthermore, the driving rod includes an integrally formed driving hard rod and a driving soft rod, the driving hard rod slides in the first cylinder and its free end slides out of the free end of the first cylinder; the driving soft rod slides in the first cylinder and the second cylinder and its extending end extending into the second cylinder is fixed at one end of the sliding rod close to the first cylinder.

[0019] Furthermore, the driving soft rod is a soft rope made of metal material.

[0020] Furthermore, the first cylinder, the second cylinder, the sliding rod, the pressure rod and the spring are all made of metal materials.

[0021] Furthermore, the driving rod is made of soft metal material. BRIEF DESCRIPTION OF THE DRAWINGS
