Description

The special-purpose drawer type of hurdle retractable door

Technical field

The utility model relates to a kind of vehicle door, is specifically related to the special-purpose drawer type of a kind of hurdle retractable door.

Background technology

Hurdle has good development abroad, and bulletproof glass for example has been installed, armor plate, shoot proof tyre.The other retainer ring that fetters, handcuffss etc. are installed of seat in hurdle, with the freedom of movement of restriction prisoner in car, and system such as GPS is installed the operating condition of hurdle can be got in touch with command centre at any time, and the interior situation of car is sent back to command centre etc. by video recording.

Because Domestic Automotive Industry is started late, most of at home hurdles are to be formed by some common passenger car transformations, and in order to ensure hurdle safety, great majority adopt and on common riding vehicle window iron bar are installed, and run away to prevent that the prisoner from jumping out from vehicle window.Because the particularity of hurdle, to anti-kidnap and anti-riot Capability Requirement very high, especially at the weapon of current crime one's share of expenses for a joint undertaking with equip under all more advanced situation, all the more so.The crime one's share of expenses for a joint undertaking will be seized prisoner the car by force outside car, and first what expect is to open car door, and the people is emitted.And existing hurdle car door is the same with the car door of common car, and its switch generally is directly installed on the car door, and the driver can easily open by hydraulic system or machine driven system, thereby and the crime one's share of expenses for a joint undertaking is also destroyed the prisoner who emits the inside from the outside with switch easily.So when running into the misfortune car, existing hurdle door is easy to open it by destroying door switch, thereby can not play the effect that prevents to rob car well.

Summary of the invention

At existing hurdle car door above shortcomings, the purpose of this utility model provides a kind of higher hurdle drawer type retractable door of anti-robbing automobile safety that aims at the hurdle design.

The technical solution of the utility model is achieved in that the special-purpose drawer type of hurdle retractable door, comprise a body, actuating unit and telescoping mechanism, actuating unit is connected with telescoping mechanism one end, the door body vertically is installed in the telescoping mechanism other end, door body upper and lower side be installed on the compartment between the lower guideway by slide mechanism and telescoping mechanism do can slide along guide rail under the sheet.

Further improve and be: described telescoping mechanism mainly is made up of screw mandrel, walking nut and some pull bars, the screw mandrel two ends are located in the screw rodb base, the screwed hole of walking nut is passed at its middle part, per two pull bars middle part intersection hinge is joined together to form one group, every group of another group pull bar head and the tail hinge connection that pull bar is adjacent, wherein the hinge of one group of pull bar is to realize by the connecting pin on the walking nut.

Further improve and be: described door body is intersected vertically by side fascia and framed side wallboard and constitutes, and side fascia is provided with cross one another reinforcement steel bar, and one supplies personnel's stair up and down to be connected with a door body hinge.

The utility model door body structure and on-off mode are very similar with drawer, so name drawer type retractable door.After adopting the retractable door of this programme, when needs pass in and outs, retractable door was stretched out under the actuating unit effect, and after personnel finished up and down, retractable door was withdrawn again, and framed side wallboard is withdrawn in the compartment fully, and its side fascia is concordant with the compartment, saw a position that is difficult to find from the outside.The retaining mechanism of this drawer type retractable door directly adopts the self-lock ability of screw mandrel to lock car door, and lock or switch and so on need be installed on door.According to people's general form of thinking, open Men Yaoxian and open lock, when the offender robs hurdle, can be because of can not find the position of door lock, and have no way of doing it.And screw mandrel is to be fully retracted in the car, can't destroy from the outside.Therefore, adopt this drawer type retractable door, can effectively reduce the prisoner in transport process, the probability of being seized by force by its partner.

The specific embodiment

Referring to Fig. 1, Fig. 2, as can be seen, the special-purpose drawer type of hurdle of the present utility model retractable door comprises a body, actuating unit and telescoping mechanism from the figure.Telescoping mechanism is made up of a screw mandrel 5, a walking nut 4 (the walking nut structure is seen Fig. 3), six pull bars 6, two fixed supporting seats 1, two screw mandrel bearings 3 and four hinge seats 2.The pull bar structure is seen Fig. 4, and its two ends and centre are equipped with connecting hole 15, and per two pull bars middle part intersection hinge is joined together to form one group, and present embodiment six pull bars form three groups of such pull bar groups.Another group pull bar that every group of pull bar is adjacent connects by connecting hole 15 hinges at two ends from beginning to end, wherein the hinge of one group of pull bar is to realize by the connecting pin on the walking nut 4 16, and promptly the connecting hole 15 in the middle of this group pull bar is sleeved on the connecting pin 16.Four terminations of the big pull bar group of three such pull bar group formation are connected with hinge seat 2 hinges respectively.Wherein one group of hinge seat 2 is fixedly mounted on two fixed supporting seats 1.The screwed hole of walking nut 4 is passed at screw mandrel 5 middle parts, and two ends are located in the screw rodb base 3.Described actuating unit is a vehicle mounted electric machine 13, and the output shaft of motor 13 is connected with screw mandrel 5 by belt pulley 14.Two fixed supporting seats 1 are near motor 13 1 sides.

Described door body is intersected vertically by side fascia 8 and framed side wallboard 9 and constitutes, and side fascia 8 is provided with cross one another reinforcement steel bar 17 (see figure 5)s, and one supplies personnel's stair 10 up and down to be connected with a door body hinge.The side fascia 8 and framed side wallboard 9 lower ends of door body are installed on the base 18, and basic 18 installed inside of door have a balance weight iron 12, and balance weight iron 12 is fixed together with another group hinge seat 2 again.Have one group of lower sheave 11 at door base 18, lower sheave 11 the door body in the effect subiculum of telescoping mechanism and is slided along floor compartment.Be provided with one group of top sheave 7 in door body upper end, top sheave 7 can slide along the guide rail that carriage top hangs down.

The side fascia of this body is used for shutoff compartment door opening, and it cooperates tightly with door opening.After the pass was shutoff behind the door, side fascia was concordant with the compartment, saw the position that is difficult to find door from the outside.When side fascia release expose door opening after, from the side fascia left and right sides all can about, the purpose of framed side wallboard is blocked a side exactly, only allows about opposite side the randomness of choice direction when having reduced up and down, safety and reliability.After door is opened, stair are put down riding on the ground, the people is by stair hurdle up and down.Fig. 6, Fig. 7 have reflected that drawer type retractable door is stretched out, the situation when withdrawing.

The special-purpose drawer type of this hurdle retractable door designs on the right side of hurdle, and its course of work is such: drive belt pulley by motor output shaft, and then drive the screw mandrel rotation by belt pulley, screw mandrel rotates drive walking nut and moves ahead, and it is flexible to drive pull bar again.Because Men Tiyu pull bar group connects, Gu Men cognition moves forward and backward (become rolling friction by sliding friction under pulley action, alleviated the resistance of motion) along guide rail.Accumulator jar on the power utilization automobile of motor, shared with car electrics.
