Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the adjustable height of the one kind proposed
Protective fence.
To achieve the goals above, the utility model adopt the technical scheme that provide it is a kind of height-adjustable anti-
Guardrail, including pedestal, the top two sides of the pedestal are symmetrically arranged with main force rod, and the top of the pedestal is located at two masters
Multiple secondary bars have been placed equidistant between power bar in the horizontal direction, have been fixedly connected with gear at the top of the secondary bar and the main force rod
Plate, and lower baffle plate is arranged at bottom margin outside the secondary bar and the main force rod；The top two sides of the overhead gage
It is provided with adjusting height button, and is fixedly connected at the top of the adjusting height button and the main force rod of two sides.
The utility model further limits technical solution, height-adjustable protective fence above-mentioned, the secondary bar and institute
Stating main force rod is to be socketed to form by three section loop bars, and the height of every section loop bar is 55-65cm.
Height-adjustable protective fence above-mentioned, the secondary bar and two main force rods are a kind of stretching structure, and
Two spacing twice between bar is respectively less than 15cm.Pass through bolt spiral at the lower baffle plate and the both sides of the edge of overhead gage to connect
There is L shape connection sheet.
Preferably, the section of multiple secondary bars and two main force rods is rectangular, the rectangular-shaped right angle
Place is equipped with round-corner transition；And the length of multiple secondary bars, width are respectively less than the length of two main force rods, width；The lower block
The outer surface of plate is provided with warning strip.
Compared with prior art, the utility model has the beneficial effects that firstly, by by two main force rods and multiple secondary bars
It stretches layer by layer, so that the height of the protective fence is adjustable to 60 centimetres, 120 centimetres and 180 centimetres, consequently facilitating
In the case that varying environment and use, the practicability of the protective fence is advanced optimized, secondly, by by overhead gage and lower baffle plate
The L shape connection sheet of two sides is combined with the connection of one or more groups of protective fences, so that the protective range of the protective fence expands, to meet
The protective fence uses in the biggish situation of protective range, and regulative mode is simple, convenient, and more preferably, also, this is anti-for protection effect
Generally a kind of stretching structure of guardrail, it is structurally reasonable, at low cost, structure is simple, height can be adjusted in a certain range to expand
Its use scope takes up space smaller when packing up, and has the effect of easy to carry, storage and dismounting.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the present embodiment provides a kind of height-adjustable protective fence, including pedestal 1, the tops of pedestal 1
Two sides are symmetrically arranged with main force rod 6, and the top of pedestal 1 has been placed equidistant with seven between two main force rods 6 in the horizontal direction
The top of secondary bar 3, seven bars 3 and two main force rods 6 is fixedly connected with overhead gage 5, and outside secondary bar 3 and two main force rods 6
Lower baffle plate 2 is arranged at bottom margin.By the way that two main force rods 6 and time bar 3 are stretched layer by layer, so that the height of the protective fence
To can tune to be 60 centimetres, 120 centimetres and 180 centimetres to degree, consequently facilitating in the case that varying environment and make
With the practicability of the protective fence being advanced optimized, by by the L shape connection sheet 7 of 2 two sides of overhead gage 5 and lower baffle plate and one group
Or the connection combination of multiple groups protective fence so that the protective range of the protective fence expands, thus meet the protective fence protective range compared with
It is used in the case where big；
The top two sides of overhead gage 5, which are provided with, adjusts height button 4, and two adjusting height buttons 4 and the Liang Ge main force
The top of bar 6 is fixedly connected, and secondary bar 3 and two main force rods 6 are to be socketed to form by three loop bars, and the height of each loop bar is
60 centimetres, secondary bar 3 and two main force rods 6 are a kind of stretching structure, so that the height of the protective fence is convenient for freely adjusting, and
Two spacing twice between bar 3 is respectively less than 15 centimetres, by the spacing between adjacent secondary bar 3 less than 15 centimetres, so that should
The protection effect of protective fence, which more preferably, at lower baffle plate 2 and the both sides of the edge of overhead gage 5 passes through bolt spiral and is connected with L shape, to be connected
Piece 7, L shape connection sheet 7 and another one or more groups of protective fences when protective range is larger, through 5 two sides of lower baffle plate 2 and overhead gage
Connection, to use meeting in larger protective range, the section of secondary bar 3 and two main force rods 6 is rounded rectangular-shaped and secondary
The length of bar 3, width are respectively less than the length of two main force rods 6, width, so that the stability of the protective fence is promoted, lower block
The front surface of plate 2 is provided with warning strip, so that the protective fence has the function of prompting and warning.
Working principle: the height-adjustable protective fence when in use, by the way that two main force rods 6 are stretched fully up
Out, secondary bar page 3 stretches finish therewith, so that the whole height of the protective fence is one meter eight, to be used as elevator fence gate, will prevent
Effect promoting is protected, height button 4 is adjusted by pressing, two main force rods 6 is packed up into a loop bar downwards, so that the protective fence
Whole height is one meter two, so that it is suitable for facing the protection of side hole, by the way that two main force rods 6 and time bar 3 are packed up still further below,
So that the whole height of the protective fence be 60 centimetres, convenient for being protected in some a lower height of sections, protective range compared with
When big, combined by the L shape connection sheet 7 of 2 two sides of overhead gage 5 and lower baffle plate with by another group of protective fence connection, so that anti-
It protects range to expand, protection effect is promoted, meanwhile, which can freely adjust the height of protective fence, not sympathized with meeting
Use under condition, and when protective fence is packed up shared small volume, carry convenient for user.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
