Abstract
The utility model discloses a tong device is prevented at qianmen of shielded cell, including being used for opening / close the actuating cylinder that drives who closes the shielded cell qianmen, still include control assembly and the panel that is located the shielded cell front end, the left and right sides that the panel is located the qianmen all is equipped with the safety cover, vertically in the safety cover install safe grating, between the two group security gratings through the transmission infrared ray at the regional protection light curtain that forms in the place ahead at qianmen, when protection light curtain is in the pass and closes the in -process and sheltered from at the qianmen, safe grating sends the shading signal to control assembly, control assembly control is driven actuating cylinder and is stopped to close and close the qianmen. Originally, prevent that the tong device sets up a pair of safe grating through the left and right sides at the shielded cell qianmen, be in to close when the qianmen and close the in -process, if in operating personnel's hand or other objects stretch into the shielded cell, drive actuating cylinder and can stop to close and close the qianmen, guarantee the safety of operating personnel when the maloperation, reduce the damage risk of shielded cell.
Description
Technical field
The utility model relates to shielded box technical field, particularly relates to a kind of Qianmen finger pinch device of shielded box.
Background technology
Shielded box is the shell utilizing conduction or permeability magnetic material to make, plate, the shield of the various shapes such as cover, electromagnetic capability is limited within the scope of certain space be used for suppressing radiation interference, and process to realize providing glitch-free test environment to tested wireless telecommunications system to conduction and radiation, because shielded box requires higher to shield effectiveness, the switch motion adopting cylinder automatically to drive Qianmen so general, when operating personnel Qianmen close in process stretch out one's hand into shielded box or in shielded box operation process maloperation start door close button time, be easy to cause operating personnel injured or damage shielded box Qianmen.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of Qianmen finger pinch device of shielded box, its handling safety, effectively can reduce the risk of personnel's maloperation.
The utility model solves the technical scheme that its technical problem adopts:
A kind of Qianmen finger pinch device of shielded box, comprise the driving cylinder for opening/closing shielded box Qianmen, also comprise Control Component and the panel being positioned at shielded box front end, the left and right sides that described panel is positioned at Qianmen is equipped with protective cover, vertically safe grating is installed in described protective cover, protection light curtain is formed by launching the front region of infrared rays at Qianmen between described two groups of safe gratings, to be in when being blocked in the process of closing at Qianmen when protecting light curtain, described safe grating sends shielding signals to Control Component, described Control Component controls to drive cylinder to stop closing Qianmen.
As the improvement of technique scheme, described driving cylinder adopts Rodless cylinder.
The beneficial effects of the utility model have:
This finger pinch device is by arranging a pair safe grating in the left and right sides at shielded box Qianmen, when Qianmen is in the process of closing, if the hand of operating personnel or other objects stretch in shielded box, drive cylinder can stop closing Qianmen, ensure the safety of operating personnel when maloperation, reduce the damage risk of shielded box.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail, wherein:
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
See Fig. 1; the Qianmen finger pinch device of a kind of shielded box of the present utility model; comprise the driving cylinder 2 for opening/closing shielded box Qianmen 1; cylinder 2 is driven to adopt Rodless cylinder; save installing space, also comprise Control Component and the panel 3 being positioned at shielded box front end, the left and right sides that panel 3 is positioned at Qianmen 1 is equipped with protective cover 4; in protective cover 4, safe grating 5 being vertically installed, between two groups of safe gratings 5, forming protection light curtain by launching the front region of infrared rays at Qianmen 1.
When Qianmen is in the process of closing; if the hand of operating personnel or other objects stretch in shielded box; when protection light curtain is blocked; safe grating 5 sends shielding signals to Control Component; Control Component controls to drive cylinder 2 to stop closing Qianmen 1; ensure the safety of operating personnel when maloperation, reduce the damage risk of shielded box.
The above, just better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, all should belong to protection domain of the present utility model.
