The utility model discloses it is rational in infrastructure, prevented to lead to the vehicle to take place to damage and fall at the lift in -process because of mechanical parking equipment's chain breaks down, ensured that the safe of vehicle goes up and down.
Description
Technical field
The utility model relates to Mechanical parking system field, specifically a kind of chain locking device.
Background technology
In prior art, Mechanical parking system needs chain by realizing elevating function, chain in daily work of long duration there will be loosening, or fracture, time in daily lifting vehicle car process, if chain ruptures suddenly and loosens all can form security threat, gently then damage car parts, heavy then may staff be accidentally injured, thus be badly in need of proposing a kind of detect chain safe condition, can when chain-loose damages the safing equipment of timely power-off.
Utility model content
The purpose of this utility model is to provide a kind of chain locking device, prevents the chain because of parking apparatus from breaking down and causing vehicle be damaged in lifting process and fall.
The technical solution of the utility model is as follows:
A kind of chain locking device, include chain, briquetting, on, lower shaft, support, baffle plate and micro-switch, it is characterized in that: the front side of described briquetting is pressed against the side of described chain, on described, the front end of lower shaft is fixedly connected on the rear side of described briquetting respectively, described baffle plate be fixedly mounted on described on, the rear end of lower shaft, described support installing is on described, on lower shaft, can along on described, lower shaft moves forward and backward, and between described briquetting and baffle plate, described is upper, lower shaft is respectively installed with Compress Spring between described briquetting and support, described micro-switch is installed on the bracket, and be positioned at the below of described baffle plate, micro-switch is connected in the current supply circuit of Mechanical parking system.
Described chain locking device, is characterized in that: described briquetting adopts nylon briquetting.
Described chain locking device, is characterized in that: described baffle plate is respectively equipped with the upper and lower through hole passed for described upper and lower axle correspondence, the rear end of described upper and lower axle is respectively equipped with outside thread, and is screwed with hold-down nut in the side, front and back of described baffle plate respectively.
Described chain locking device, is characterized in that: the contact part of described micro-switch is positioned at the front of described baffle plate.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, and when normally working, Compress Spring is compressed, and baffle plate and micro-switch are in released state, and the current supply circuit of Mechanical parking system is in closure state; During when chain is in fracture and is lax, baffle plate will be touched and extrude the contact part of micro-switch, thus make the current supply circuit of Mechanical parking system be in off-state, now Mechanical parking system is out of service, prevent the chain because of Mechanical parking system break down and cause vehicle be damaged in lifting process and fall, ensure the safety lifting of vehicle.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
See Fig. 1, a kind of chain locking device, include chain 8, briquetting 1, on, lower shaft 4, support 3, baffle plate 5 and micro-switch 7, the front side of briquetting 1 is pressed against the side of chain 8, on, the front end of lower shaft 4 is fixedly connected on the rear side of briquetting 1 respectively, baffle plate 5 is fixedly mounted on, the rear end of lower shaft 4, support 3 is arranged on, on lower shaft 4, can along upper, lower shaft 4 moves forward and backward, and between briquetting 1 and baffle plate 5, on, lower shaft 4 is respectively installed with Compress Spring 2 between briquetting 1 and support 3, micro-switch 7 is arranged on support 3, and be positioned at the below of baffle plate 5, micro-switch 7 is connected in the current supply circuit of Mechanical parking system.
In the utility model, briquetting 1 adopts nylon briquetting.
Baffle plate 5 is respectively equipped with keep supplying, upper and lower through hole that lower shaft 4 correspondence is passed, the rear end of upper and lower axle 4 is respectively equipped with outside thread, and is screwed with hold-down nut 6 in the side, front and back of baffle plate 5 respectively.
The contact part of micro-switch 7 is positioned at the front of baffle plate 5.
Below in conjunction with accompanying drawing, the utility model is further described:
When Mechanical parking system normally works, briquetting 1 is pressed against the side of chain 8, and Compress Spring 2 is compressed, and baffle plate 5 and micro-switch 7 are in released state, and the current supply circuit of Mechanical parking system is in closure state.During when chain 8 is in fracture and is lax, Compress Spring 2 pressure release is stretched, under the effect of Compress Spring 2, support 3 drives micro-switch 7 to move backward along upper and lower axle 4, baffle plate 5 will be touched and extrude the contact part of micro-switch 7, thus make the current supply circuit of Mechanical parking system be in off-state, now Mechanical parking system is out of service, prevents the chain 8 because of Mechanical parking system break down and cause vehicle be damaged in lifting process and fall.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement; or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount the scope that the utility model defines, protection domain of the present utility model all should be belonged to.
