Description
Technical field
The utility model relates to safeguard technical field, specifically a kind of anti-one-sided open-type protective hurdle.
Background technology
Protective guard, as one of conventional safeguard, is widely used in road, bridge, house and mobile device, on train, automobile, steamer.The access place of protective guard is generally provided with the door rotatably opened, the general people of keeper of guardrail can open from side, but in more dangerous place, as the train of movement, automobile etc., the guardrail that can open from side easily easily occurs because the maloperation of people causes guardrail to be opened, have an accident, therefore guardrail pins by the conventional lock of people, when needed guardrail is opened, but this mode not only needs to increase lockset, increase equipment cost, and the frequent locking of lockset is opened and is lost time, reduce operating efficiency, if and key prepares not in time, delay opening in time of guardrail, easily lifesaving is affected in critical situation, in addition, for the guardrail access that magnitude setting is more, lockset key is easily chaotic, be unfavorable for management, easily affect opening in time of guardrail access equally.
Summary of the invention
Easily occur maloperation, the problem that the protective guard locked often can not be opened in time to solve common protective guard, the utility model provides a kind of anti-one-sided open-type protective hurdle.
The utility model solves its technical problem and realizes by the following technical solutions:
A kind of anti-one-sided open-type protective hurdle, comprise breast board and column, described breast board forward upper is provided with keeper cover, keeper is provided with in described keeper cover, the left part of described keeper is provided with taper surface, keeper is provided with cannelure, cavity is provided with in described column, column rear end face bottom is provided with bottom side hole, column is provided with the jack coordinated with keeper relative to the side of keeper, described cavity inside upper part is provided with slideway, the limited block that can slide in slideway is provided with in described slideway, the width of described limited block is less than the width of cannelure, so that limited block snaps in cannelure, the upper end of limited block is connected with extension spring, the lower end of limited block is connected with drag-line, the lower end of described drag-line is connected with pedal, and drag-line is connected to the front end of pedal, described pedal is positioned at bottom side hole, the rear end of pedal is hinged on the base plate of column, during use, pushes pedals, rotating around pin joint of the base plate of pedal itself and column, pedal front end pulls drag-line to move down, thus make limited block slide downward in slideway.
The upper end of described limited block is provided with the cambered surface groove coordinated with cannelure, and the radius of curvature of described cambered surface groove is identical with the radius of curvature of cannelure.
The extension spring that described limited block connects has two, and lays respectively at the both sides of cambered surface groove, and extension spring is used for limited block is resetted, and the structure that two extension springs are carried out straining from limited block both sides respectively can to balanced action the movement of limited block.
The bottom surface of described cambered surface groove is concordant with the bottom surface of cannelure, when keeper is entered the cambered surface groove of upper limit position block through jack, due to the bottom surface of cambered surface groove and the bottom surface of cannelure concordant, and the diameter of keeper is greater than the diameter of cannelure, keeper will press limited block downwards, under the effect of extension spring, limited block is keeper upwardly, when limited block is stuck in cannelure, keeper can not be extracted, the left end of described keeper is arc surface, to make keeper be pushed away by limited block downwards, the keeper end of plane is prevented to be pressed on limited block, and the component promoted by limited block can not be produced downwards.
The beneficial effects of the utility model are: the utility model adopts the two-sided mode opened, list can not open keeper from side, effectively prevent the generation of maloperation, only have when protective guard outside has personnel to coordinate protective guard internal staff to push down on the pedal, protective guard internal staff is stretchy keeper, protective guard is opened, eliminate the use of lockset, protect protective guard internal staff, especially easily there is the safety of the children of maloperation, under inside and outside personnel's compounding practice, open conveniently, when avoiding employing lockset, due to the problem that finding key causes protective guard not open in time.

Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figures 1 to 8, a kind of anti-one-sided open-type protective hurdle, comprise breast board 1 and column 4, described breast board 1 forward upper is provided with keeper cover 2, keeper 3 is provided with in described keeper cover 2, the left part of described keeper 3 is provided with taper surface 302, keeper 3 is provided with cannelure 301, cavity 4a is provided with in described column 4, column 4 rear end face bottom is provided with bottom side hole 4b, column 4 is provided with the jack 4d coordinated with keeper 3 relative to the side of keeper 3, described cavity 4a inside upper part is provided with slideway 4c, the limited block 7 that can slide in slideway 4c is provided with in described slideway 4c, the width of described limited block 7 is less than the width of cannelure 301, the upper end of limited block 7 is connected with extension spring 6, the lower end of limited block 7 is connected with drag-line 5, the lower end of described drag-line 5 is connected with pedal 8, and drag-line 5 is connected to the front end of pedal 8, described pedal 8 is positioned at bottom side hole 4b, the rear end of pedal 8 is hinged on the base plate of column 4, during use, pushes pedals 8, pedal 8 rotates around pin joint, pedal 8 front end pulls drag-line 5 to move down, thus make limited block 7 slide downward in slideway 4c.
The upper end of described limited block 7 is provided with the cambered surface groove 7a coordinated with cannelure 301, and the radius of curvature of described cambered surface groove 7a is identical with the radius of curvature of cannelure 301.
The extension spring 6 that described limited block 7 connects has two, and lays respectively at the both sides of cambered surface groove 7a, and extension spring 6 resets for making limited block 7, and the structure that two extension springs 6 are carried out straining from limited block 7 both sides respectively can to balanced action the movement of limited block 7.
The bottom surface of described cambered surface groove 7a is concordant with the bottom surface of cannelure 301, during use, when keeper 3 is entered the cambered surface groove 7a of upper limit position block 7 through jack 4d, because the bottom surface of cambered surface groove 7a is concordant with the bottom surface of cannelure 301, and the diameter of keeper 3 is greater than the diameter of cannelure 301, keeper 3 will press downwards limited block 7, under the effect of extension spring 6, limited block 7 is keeper 3 upwardly, when limited block 7 is stuck in cannelure 301, keeper 3 can not be extracted, the left end of described keeper 3 is arc surface, to make keeper 3 be pushed away by limited block 7 downwards, prevent keeper 3 end of plane from killing on limited block 7, when needing the access of opening protective guard, protective guard external staff pushes pedals 8, pedal 8 is utilized to be pulled down by drag-line 5, limited block 7 is pulled downwards, deviate from cannelure 301, thus protective guard internal staff can pull open keeper 3, open protective guard, simple to operate, protection is reliable, after pedal 8 is released, extension spring 6 pulls on limited block 7 and moves reset, to carry out locking next time.
