Description
Technical field
The utility model relates to a kind of testing machine safety protective door.
Background technology
Testing machine is a kind of checkout equipment of test concrete test block and reinforcing bar tensile strength, and in test process, measured piece will bear very big impact force and pulling force, causes fragment to splash, so there is bigger danger in test process.And the opening and closing operations of the protective door of traditional experiment machine is a hand, inconvenient operation, and have certain potential safety hazard.
Summary of the invention
In order to overcome conventional test machine protective door inconvenient operation in the prior art, use not too safe problem, the utility model provides a kind of testing machine safety protective door, this testing machine safety protective door simple and compact for structure, easy to operate, safe and reliable.
The technical scheme that its technical problem that solves the utility model adopts is: comprise the last valve in doorframe and the doorframe, following valve, link to each other with foot rest by assembly pulley and drag-line with following valve at last valve, connect back-moving spring on the foot rest.
Assembly pulley comprise the tenesmus assembly pulley, on draw assembly pulley, switching pulley and bus pulley, the tenesmus assembly pulley connects valve down by drag-line, on draw assembly pulley connect to go up valve by drag-line, the drag-line of tenesmus assembly pulley directly joins with the drag-line that passes the bus pulley, on draw the drag-line of assembly pulley to join by switching pulley and the drag-line that passes the bus pulley.
The tenesmus assembly pulley comprises two tenesmus pulleys of both sides, doorframe upper end, the drag-line that passes the tenesmus pulley connects the two ends of valve down, on draw assembly pulley to comprise to draw pulley and a branch rope pulley on two, pass drag-line behind the branch rope pulley and be divided into two stocks and do not pass and draw pulley to connect the two ends of going up valve on two.
The utility model is by above-mentioned specific design, only needs foot pedals can realize the switching of testing machine safety protective door, and operation is very easy, and protective door close tightly, have simple and compact for structure, safe and reliable advantage.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the utility model comprises the last valve 2 in doorframe 1 and the doorframe 1, following valve 3, links to each other with foot rest 5 by assembly pulley and drag-line with following valve 3 at last valve 2, connects back-moving spring 8 on the foot rest 5.Assembly pulley comprise the tenesmus assembly pulley, on draw assembly pulley, switching pulley 6 and bus pulley 7, the tenesmus assembly pulley connects valve 3 down by drag-line 4A, on draw assembly pulley to pass through valve 2 in the drag-line 4B connection, the drag-line 4A of tenesmus assembly pulley directly joins with the drag-line 4C that passes bus pulley 7, on draw the drag-line 4B of assembly pulley to join with the drag-line 4C that passes bus pulley 7 by switching pulley 6.The tenesmus assembly pulley comprises two tenesmus pulleys 9 of both sides, doorframe upper end, the drag-line 4A that passes tenesmus pulley 9 connects the two ends of valve 3 down, on draw assembly pulley to comprise to draw pulley 10 and a branch rope pulley 11 on two, pass drag-line 4B behind the branch rope pulley 11 and be divided into two stocks and do not pass and draw pulley 10 to connect the two ends of going up valve 2 on two.When stepping on foot rest 5 down in working order, back-moving spring 8 is stretched, drag-line 4C drives drag-line 4A and drag-line 4B, drag-line 4A loses following pining down of valve 3, downward sliding opening under the action of gravity of following valve 3, simultaneously, drag-line 4B draws high valve 2, last valve 2 is sliding opening upwards, and dodge gate is in opening, when unclamping foot rest 5, back-moving spring 8 drive foot rests 5 reset and lift, drag-line 4C drives drag-line 4A and drag-line 4B, and drag-line 4A draws high down valve 3, and following valve 3 is sliding closing upwards, simultaneously, drag-line 4B loses the pining down of last valve 2, last valve 2 sliding closing downwards under action of gravity, and dodge gate is in closed condition.Above-described embodiment only is that the preferred implementation to the utility model testing machine safety protective door is described; be not that design and scope to utility model limits; under the prerequisite that does not break away from the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model all should fall into the protection domain of the utility model testing machine safety protective door.
