Problems solved by technology
[0003] The purpose of the present invention is to provide a traction-type anti-hijacking device for cars, which solves the problem that the existing transmission mechanism is affected by the limited space occupied by the overall structure, the motor can only be placed behind the seat, and the reset operation is inconvenient and other problems, its structural design is more compact and reasonable. In addition to still having the advantages of light, flexible and stable lifting, it also reduces parts, saves raw materials, and significantly reduces the occupied space of the seat bottom. The reset operation is quick and convenient. Further improve the safety and reliability of use

Embodiment Construction
[0025] according to Figure 1-13 The specific structure of the present invention will be described in detail. The traction-type anti-hijacking device for cars is improved on the basis of the applicant's "Tow-type anti-hijacking device for cars" (application publication number is CN103303243A). It includes the upper and lower beam assemblies 1 and 2 assembled at the bottom of the seat in the car, and the transmission mechanism assembly 3 which adopts two sets of transmission mechanisms symmetrically arranged. Wherein the upper beam assembly 1 includes an upper beam 15 and a fixing seat 16 which is arranged on the upper beam 15 and can hinge the upper and lower support rods 10 and the like. Upper beam 15 is fixed on the bottom of the seat cushion of seat, and upper beam 15 below is provided with the positioning pin 4 that can restore original position, so that upper beam 15 can return to the position before moving smoothly after lifting. The lower beam assembly 2 includes a lo...

Disclosed is a traction type anti-hijack device for a saloon car. The problems that an existing transmission mechanism is large in finite space occupied by the overall structure, and the resetting operation is inconvenient are solved. The traction type anti-hijack device comprises an upper beam assembly, a lower beam assembly and a transmission mechanism assembly with two sets of transmission mechanisms arranged symmetrically, and the upper beam assembly and the lower beam assembly are assembled at the bottoms of seats in the car. The traction type anti-hijack device is characterized in that the positions of motors, fixedly arranged on a movable base plate, in existing transmission mechanisms are reset, driven wheels in an original traction component are eliminated, sliding blocks with connecting lugs parallel to the axis of a central hole are assembled in a sleeve, and the upper end faces and the lower end faces of the connecting lugs axially moving along sleeve pipe guide sliding grooves cannot exceed the upper end faces and the lower end faces of the sleeve pipe guide sliding grooves. Due to the fact that the device is more compact and reasonable in structural design, the device achieves the advantages of the existing transmission mechanisms of being convenient to hoist, flexible and smooth, parts are reduced, raw materials are saved, the occupied space of the bottoms of the seats is obviously reduced, the resetting operation is fast and convenient, and use safe reliability is further improved.
Description
technical field [0001] The invention relates to a safety protection device for a car, in particular to a traction-type anti-hijacking device for a car which is specially used to prevent a taxi driver from being attacked by people in the car. Background technique [0002] Existing safety anti-hijacking devices for cars used to protect taxi drivers from being attacked by people in the car generally adopt components such as isolation guardrails installed in the car to separate the driver from the people in the car to protect the driver. . Some also use sound and light alarm devices to call for help. The applicant has successively designed the "anti-hijacking device for cars" whose application publication number is CN102862542A, and the "traction-type anti-hijacking device for cars" whose application publication number is CN103129503A. Among them, due to the complex structure of the transmission mechanism assembly of the "anti-hijacking device for cars", the transmission effic...
