Description
Technical field
The present invention relates to a kind of instrument, particularly relate to a kind of ladder.
Background technology
Ladder is one of instrument that often can use in people's daily life; existing ladder does not carry tool box; first people will carry instrument carefully in use; if it is just cumbersome to can not find instrument for the moment, use inconvenience, in addition; when people stand in the top of ladder; if do not have other objects to allow operating personnel hold up as handrail, operating personnel easily drop down from ladder, use dangerous.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of ladder of new structure, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of ladder easy to use, safe.
Ladder of the present invention, comprise two connectors, the bottom surface of described connector offers storage tank, the first support bar and the second support bar is provided with in described storage tank, the top of described first support bar and the top of the second support bar are hinged on connector respectively, and be provided with the first terraced bar between the first support bar in left side and the first support bar on right side, on the first support bar on the left of one end of described first terraced bar is fixedly installed on and is positioned at, on the first support bar on the right side of the other end of the first terraced bar is fixedly installed on and is positioned at, the second terraced bar is provided with between the second support bar in left side and the second support bar on right side, on the second support bar on the left of one end of described second terraced bar is fixedly installed on and is positioned at, on the second support bar on the right side of the other end of the second terraced bar is fixedly installed on and is positioned at, the end face of described connector is provided with expansion link, the bottom of described expansion link is fixedly installed on the end face of connector, also casing is provided with between two connectors, on connector on the left of the side of described casing is fixedly installed on and is positioned at, on connector on the right side of the opposite side of casing is fixedly installed on and is positioned at, the top of described casing is provided with top cover.
By such scheme, the present invention at least has the following advantages: ladder of the present invention comprises connector, the number of connector is two, connector is hinged with the first support bar and the second support bar, be provided with the first terraced bar between first support bar, be provided with the second terraced bar between the second support bar, the end face of connector is provided with telescopic rod, be provided with casing between two connectors, the top of casing is provided with top cover.During concrete use, due to the setting of casing, instrument conventional at ordinary times can be placed in casing by operating personnel, and covers with top cover, thus makes operating personnel just can find the instrument of needs without the need to finding tool box when using ladder from tool box, very easy to use, in addition, the setting of telescopic rod, make operating personnel can be hand steered when standing on top cover the expansion link of the left and right sides, thus operating personnel are not easily dropped down from ladder, use very safe.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of manual, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of ladder of the present invention;
Fig. 2 is the left view of Fig. 1.
In figure, 1: connector; 2: storage tank; 3: the first support bars; 4: the second support bars; 5: the first terraced bars; 6: expansion link; 7: casing; 8: top cover.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
See Fig. 1 and Fig. 2, a kind of ladder of a preferred embodiment of the present invention, comprise two connectors 1, the bottom surface of connector offers storage tank 2, the first support bar 3 and the second support bar 4 is provided with in storage tank, the top of the first support bar and the top of the second support bar are hinged on connector respectively, and be provided with the first terraced bar 5 between the first support bar in left side and the first support bar on right side, on the first support bar on the left of one end of first terraced bar is fixedly installed on and is positioned at, on the first support bar on the right side of the other end of the first terraced bar is fixedly installed on and is positioned at, the second terraced bar (not shown) is provided with between the second support bar in left side and the second support bar on right side, on the second support bar on the left of one end of second terraced bar is fixedly installed on and is positioned at, on the second support bar on the right side of the other end of the second terraced bar is fixedly installed on and is positioned at, the end face of connector is provided with expansion link 6, the bottom of expansion link is fixedly installed on the end face of connector, casing 7 is also provided with between two connectors, on connector on the left of the side of casing is fixedly installed on and is positioned at, on connector on the right side of the opposite side of casing is fixedly installed on and is positioned at, the top of casing is provided with top cover 8.
During concrete use, due to the setting of casing, instrument conventional at ordinary times can be placed in casing by operating personnel, and covers with top cover, thus makes operating personnel just can find the instrument of needs without the need to finding tool box when using ladder from tool box, very easy to use, in addition, the setting of telescopic rod, make operating personnel can be hand steered when standing on top cover the expansion link of the left and right sides, thus operating personnel are not easily dropped down from ladder, use very safe.
The above is only the preferred embodiment of the present invention; be not limited to the present invention; should be understood that; for those skilled in the art; under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
