Description
Technical field
The utility model relates to a kind of van, belongs to the technical field of transport vehicle.
Background technology
Van is established expansion tank in the both sides of envelope usually in addition in order to enlarge the usage space of envelope.The tradition van, comprise envelope, expansion side plate, mobilizable and the described envelope in described expansion side plate lower end links into an integrated entity, and described envelope is respectively equipped with a connecting device with expansion side plate coupling end both sides, and the side plate of expansion tank is generally connected its expansion, gathering by connecting device.When van side plate of the prior art is expanded, connecting device generally is a chain, the chain two ends are connected on side plate and the envelope, and the connecting device of this structure is because chain is a rigid member, there is not retractility, and side plate is when opening, and opening speed is very fast, and chain is not having under the situation of cushion effect, easily because of disconnection produces danger, thereby reduced the safety of van; In addition, when side plate was packed up, because the chain inductility, the gathering of side plate relied on manpower to finish fully, and therefore, side plate draws relatively effort in, and the side plate to gathering do not have auxiliary locking effect.
The utility model content
Above-mentioned defective when expanding for overcoming existing van side plate, the utility model provides a kind of van, and this van has the Joint strenght height, characteristics safe in utilization.
In order to solve the problems of the technologies described above, a kind of van of the utility model, comprise envelope, the expansion side plate, mobilizable and the described envelope in described expansion side plate lower end links into an integrated entity, described envelope is respectively equipped with a connecting device with expansion side plate coupling end both sides, described connecting device comprises body, spring, the rope body, what described body was vertical is fixedly installed on the described compartment, described spring is arranged in the described body, described rope body one end passes described spring, the unrolled suspension ring of described spring and described spring upper end, and with mobilizable the linking into an integrated entity of described rope body, the described rope body other end extends described body captives joint with the side plate of described van and is integral.
Above-mentioned a kind of van, wherein, described body periphery is provided with a wheel shaft, described wheel shaft and described body is rotating links into an integrated entity, described rope body is on described wheel shaft periphery.
Above-mentioned a kind of van, wherein, described body lower end is provided with a roller, the rotating described body lower end that is arranged on of described roller, described rope body is on the periphery of described roller.
The utility model can be realized following effect:
1, because van comprises body, rope body and spring, contractility by spring makes the expansion side plate draw in, expand, when gathering of expansion side plate or expansion, the contractility of spring can play the effect of buffering and damping to the expansion side plate, the safety when having improved the extended operation of expansion side plate; And when the expansion side plate drew in, the elastic force of spring can play certain pulling force, thereby had made things convenient for the gathering of expansion side plate, and the expansion side plate that draws in is played auxiliary locking effect, had increased the Joint strenght of van, and had improved the safety of van.
2, because the body periphery is provided with wheel shaft, the rope body is around the periphery of wheel shaft, and wheel shaft can play directional tagging to the rope body, makes connecting device easy to use.
3, because the body lower end is provided with roller, the rope body is around the periphery of roller, and roller not only can play directional tagging to the rope body, the convenient use, and the body of can also avoiding restricting damages owing to the friction of body, thereby has prolonged the service life of connecting device.
Description of drawings

Fig. 2 is the cutaway view of the A-A of Fig. 1
The specific embodiment
Below in conjunction with accompanying drawing to the utility model with further specifying.
As Fig. 1, shown in 2, in order to solve the problems of the technologies described above, a kind of van of the utility model, comprise envelope 10, expansion side plate 5, described expansion side plate 5 lower ends link into an integrated entity by hinge or the mobilizable and described envelope 10 of other modes, described envelope 10 is respectively equipped with a connecting device with the both sides of expansion side plate 5 coupling ends, connecting device comprises body 2, spring 1, rope body 4, described body 2 vertical being fixedly installed on the described envelope, described spring 1 is arranged in the described body 2, described rope body 4 one ends pass described spring 1, the unrolled suspension ring 11 of described spring 1 and described spring 1 upper end, and with described rope body 4 by latch closure or other modes are mobilizable links into an integrated entity, described rope body 4 other ends extend described body 1 lower end, and captive joint and be integral with expansion side plate 5, suspension ring 11 are fixedly connected on the upper end of body 2.The solid drawn pipe that body 2 adopts corrosion-resistant steel to make usually, rope body 4 is generally the corrosion-resistant steel steel rope because connecting device comprises body 2, rope body 4 and spring 1, contractility by spring 1 makes side plate 5 draw in, expand, when side plate 5 expansions, the contractility of spring 1 can play the effect of buffering and damping to side plate 5; Safety when having improved the side plate extended operation, and under side plate 5 rounding states, spring 1 can play auxiliary locking effect to side plate.
For easy to use, described body 2 peripheries are provided with a wheel shaft 3, described wheel shaft 3 links into an integrated entity by rotating shaft and described body, rotating shaft one end is fixedly connected on the body outer peripheral face, the other end passes the wheel shaft centre hole, and wheel shaft 3 can be rotated relative to body 2, and described rope body 4 is on described wheel shaft periphery, during use, rope body 4 can circumferentially slide along wheel shaft 3.Because body 2 peripheries are provided with wheel shaft 3, wheel shaft 3 can play directional tagging to rope body 4, and it is convenient that connecting device is used.
In order to prolong the service life of connecting device, described body 2 lower ends are provided with a roller 21, the described roller 21 rotating lower ends that are arranged on described body 2, described rope body 4 is on the periphery of described roller 21, roller 21 can be used with wheel shaft 3, promptly restrict body 4 on roller 21 peripheries after again on wheel shaft 3 peripheries; Also roller 21 can be used separately, rope body 4 on roller 21 peripheries after again direct connection on the inside face of side plate 5.Because body 2 lower ends are provided with roller 21, rope body 4 is around the periphery of roller 21, during use, the rope body rotates along the periphery of roller, and roller 21 not only can play directional tagging to rope body 4, the convenient use, because roller 21 outside faces are smoother, and the friction of rope body 4 and roller 21 is rolling friction, can avoid the bottom face of body 2 that rope body 4 is caused damage, prevent to restrict body 4 because of friction is damaged, thereby prolonged the service life of connecting device.
In sum, the utility model compared with prior art owing to adopt steel pipe and spring to make, therefore, compact conformation, safe in utilization, be specially adapted to damping, the buffering of bigger expansion side plate; And under the side plate state, the elastic force by spring also can play auxiliary locking effect to side plate, thereby has improved the safety performance of van greatly.
Here description of the invention and application is illustrative, is not to want that therefore, the present invention is not subjected to the restriction of present embodiment with scope restriction of the present invention in the above-described embodiments, and the technical scheme that any employing equivalence replacement obtains is all in the scope of protection of the invention.
