Abstract
The utility model belongs to the technical field of an accessory of oil equipment vehicle and specifically relates to a folding handrail that and folding ladder cooperation application. Include: go up fixing device, handrail, the fixed clamp of shock attenuation and fixing device down, the handrail both ends through last fixing device and fixing device down through interior heavy screw fixation on the bulkhead and can use it to be the axle and rotate, the fixed clamp setting of shock attenuation on the bulkhead and when the handrail rotatory extremely with the bulkhead when parallel the shock attenuation fix the clamp can the chucking handrail. The utility model discloses an useful part be: through above -mentioned structural design, the handrail can conveniently be opened when needs use and be fixed, can conveniently fold again in the time of need not using, can not lead to the fact after folding the automobile body super wide and because the handrail can be fixed with the bulkhead through the fixed clamp of shock attenuation, the problem of having avoided folding back bar collided with by vibrations and bulkhead, and whole practicality is just with low costs by force, is suitable for very much and uses widely.
Description
Technical field
The utility model relates to a kind of accessory field of petroleum equipment vehicle, especially a kind ofly coordinates the stow-away arm rest used with attic ladder.
Background technology
The superimposed trailer of oil equipment is often used in the work progress in petroleum engineering field, car is generally provided with operation cabin, because position, cabin is higher, staff needs climbing attic ladder turnover cabin, at present, domestic attic ladder does not arrange stow-away arm rest substantially, potential great risk in staff's work; And the fixed block thickness of external stow-away arm rest is comparatively large, after installation, easily cause car body ultra-wide, and launch at handrail, very inconvenient in folding process, and when folding rear vehicle is run handrail easily and bulkhead collide.
Utility model content
For above-mentioned deficiency, the utility model provides the special superimposed trailer of a kind of Large Copacity roller of continuous oil pipe.
The utility model is achieved through the following technical solutions:
A kind of new type foldable handrail, comprise: upper anchor fitting, handrail, damping fixing hoop and lower anchor fitting, handrail two ends to be fixed on bulkhead by upper anchor fitting and lower anchor fitting and can with it for axle rotate, and damping fixing hoop to be arranged on bulkhead and can to clamp handrail when handrail rotates to damping fixing hoop time parallel with bulkhead.
Preferably, the upper anchor fitting had for the utility model comprises: have the upper fixed block of fixed orifice, rotating shaft a, spring a, and rotating shaft a is successively through handrail, spring a and upper fixed block.
Preferably, the lower anchor fitting had for the utility model comprises: have the lower fixed block of fixed orifice, rotating shaft b, spring b, locating dowel pin, spacing hole is provided with bottom lower fixed block, rotating shaft b is successively through handrail, spring b, lower fixed block and locating dowel pin, when handrail is parallel with bulkhead, spring b is state of nature, when handrail is vertical with bulkhead, spring b compresses and makes rotating shaft b carries, and locating dowel pin injects spacing hole, and rotating shaft b lower end is provided with swing handle.
Preferably, the upper and lower anchor fitting had for the utility model and the fixing of bulkhead are realized by interior heavy screw.
Preferably, the thickness of the upper and lower fixed block had for the utility model is not more than 23mm.
The usefulness of this utility model is: designed by said structure, handrail can be easy to open when needs use and fix, do not need can conveniently fold again when using, car body ultra-wide can not be caused after folding and can be fixed by damping fixing hoop and bulkhead due to handrail, avoid the problem that folding back bar collides with by vibrations and bulkhead, overall utility is strong and cost is low, is very suitable for promoting the use of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the section-drawing of the utility model handrail and damping fixing hoop;
Fig. 3 is the structural representation of anchor fitting on the utility model;
Fig. 4 is the structural representation of anchor fitting under the utility model.
In figure, 1, upper anchor fitting, 2, handrail, 3, damping fixing hoop, 4, lower anchor fitting, 5, upper fixed block, 6, fixed orifice, 7, spring a, 8, rotating shaft a, 9 times fixed blocks, 10 spring b, 11, rotating shaft b, 12, spacing hole, 13, locating dowel pin, 14 swing handles.
Detailed description of the invention
Now by reference to the accompanying drawings detailed description of the invention of the present utility model is described further:
A kind of new type foldable handrail, comprise: upper anchor fitting 1, handrail 2, damping fixing hoop 3 and lower anchor fitting 4, handrail 2 two ends to be fixed on bulkhead by interior heavy screw by upper anchor fitting 1 and lower anchor fitting 4 and can with it for axle rotate, and damping fixing hoop 3 to be arranged on bulkhead and can to clamp handrail 2 when handrail 2 rotates to damping fixing hoop 3 time parallel with bulkhead.Upper anchor fitting 1 comprises: have fixed orifice 6 and thickness is not more than upper fixed block 5, spring a7, the rotating shaft a8 of 23mm, and rotating shaft a8 is successively through handrail 2, spring a7 and upper fixed block 5.Described lower anchor fitting 4 comprises: have fixed orifice 6 and thickness is not more than lower fixed block 9, spring b10, rotating shaft b11, the locating dowel pin 13 of 23mm, spacing hole 12 is provided with bottom lower fixed block 9, rotating shaft b11 is successively through handrail 2, spring b10, lower fixed block 9 and locating dowel pin 13, when handrail 2 is parallel with bulkhead, spring b10 is state of nature, when handrail 2 is vertical with bulkhead, spring b10 compresses and makes rotating shaft b11 carries, locating dowel pin 13 injects spacing hole 12, and rotating shaft b11 lower end is provided with swing handle 14.
The utility model concrete operations and sequence of operation as follows:
When needing to open this stow-away arm rest, rotating handrail 2 is to vertical with bulkhead, and spring b tensioning promotes lower fixed block 9 makes locating dowel pin 13 inject in spacing hole 12, and now handrail 2 is fixed, and facilitates librarian use.
When needing this stow-away arm rest folding, pull swing handle to carry for 14 times, make locating dowel pin 13 depart from spacing hole 12, handrail 2 to parallel with bulkhead, and sticks in damping fixing hoop 3 by rotating handrail 2, and when ensureing that vehicle travels, handrail 2 can not collide with bulkhead because being given a shock.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, done any amendment, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
