Moving end-wall 3 is fixedly connected；
The pressure-bearing moving tube 2 is used to when inflated, it is mobile to 10 direction of shelf body to push moving end-wall 3, and in quilt
When deflation, pull moving end-wall 3 to far from the movement of 10 direction of shelf body.
It should be noted that fixation wall 1 is connected with the fixed bracket in outside, the fixation of position is realized.
In specific implementation, the medial surface (i.e. close to one end of shelf body) of each moving end-wall 3 is provided with clamping spongy layer
4。
In specific implementation, each pressure-bearing moving tube 2 includes hollow outer tube 204 and mobile inner sleeve 205, described
Mobile inner sleeve 205 is nested in outer tube 204；
The outer tube 204 is fixedly connected with fixation wall 1, is specifically as follows: by a fixing bolt foot 202 and being fixed
Wall 1 is fixedly connected；
The outer tube 204 is connected by hollow pipeline with inflator pump 5；
The outboard end of outboard end (one end i.e. far from shelf body 10) and outer tube 204 of the mobile inner sleeve 205
A back-moving spring 203 is fixedly connected between inner wall.Therefore, mobile inner sleeve 205 can be on the one hand avoided to be detached from, another party
Face can retract mobile inner sleeve 205 when pressure-bearing moving tube 2 bleed off pressure in pipe.
In specific implementation, a gas tube 201, the gas tube 201 and institute are provided on the side wall of the outer tube 204
It states 204 inner space of outer tube to be connected, the gas tube 201 is connected by hollow pipeline with inflator pump 5.
In specific implementation, the outer wall of the mobile inner sleeve 205 is fixed with a sealing ring 206.The sealing ring tool
Body is connected using screw thread with the outer wall of mobile inner sleeve 205.
In specific implementation, the inner end of the sealing ring 206 and the outer tube 204 is (i.e. close to the one of shelf body 10
End) between be provided with a sealing telescopic 207；
The outboard end (one end i.e. far from shelf body 10) of the sealing telescopic 207 is interior with the outer tube 204
Side is connected, it is described sealing telescopic 207 inner end be connected with the outboard end of the sealing ring 206, so as to
Mobile inner sleeve 205 and sealing ring 206 thereon movement and free extension, realize good damping, buffering effect.
In specific implementation, the sealing telescopic 207 can be the rubber sleeve of elasticity.
In specific implementation, be provided on the pipeline between the inflator pump 5 and the outer tube 204 charge valve 6 and
Vent valve 7.
It should be noted that for the utility model, when opening charge valve 6 and inflator pump 5, in the effect of inflator pump 5
Under, the air of external high pressure enters multiple pressure-bearing moving tubes 2 by pipeline simultaneously；It is connected with vent valve 7 on pipeline simultaneously, is being put
When air valve 7 is opened, the pressure-air in pressure-bearing moving tube 2 and pipeline can be discharged into atmosphere.
After being filled with pressure-air in mobile pressure-bearing pipe 2, it will push mobile inner sleeve 205 and moving end-wall 3 thereon, clamp
Spongy layer 4 is displaced outwardly together, and then is clamped to the packing case placed in the shelf body of inside, i.e., by two clamping machines
Structure 20 carrys out the packing case on horizontal clamping shelf, so that without laterally between two packing cases of the arbitrary neighborhood placed on shelf
Gap, avoid the bypass problem of air, at this time, cold wind can be allowed to flow through packing case from top to bottom or from the bottom up, kept away
The bypass for having exempted from air, the air for compeling to be used in pre-cooling all flow through venthole at left and right sides of packing case, improve to packing case
The pre- cold efficiency of the cargo of interior placement.It should be noted that back-moving spring 203 extends at this time, sealing telescopic 206 stretches.
When due to opening vent valve 7, so that back-moving spring 203 is shunk when decrease in air pressure in mobile pressure-bearing pipe 2,
And pull mobile inner sleeve 205 and be thereon moving end-wall 3, clamp spongy layer 4 move inward, while seal telescopic 206 contraction,
At this time, the packing case on two clamp systems 20 no longer horizontal clamping shelf, consequently facilitating carrying out pre-cooling behaviour to packing case
After work, user is allowed to move in time packing case.
For the utility model, it is directed to during vertical ventilation differential pressure precooling, on shelf by the periphery air quantity of packing case
Topic of corresponding is designed.The utility model is connected to realize with pressure-bearing moving tube by carrying out inflation/deflation to pressure-bearing moving tube
The moving end-wall of connection and the displacement for clamping spongy layer so that two packing cases of the arbitrary neighborhood placed on shelf it
Between not lateral gap therefore when cold wind is blown from top to bottom or from the bottom up, avoid the bypass of air, force
Air for pre-cooling all flows through the venthole at left and right sides of packing case, improves the pre-cooling to the cargo placed in packing case and imitates
Rate improves the effect of pre-cooling, and the high-efficiency popularization for vertical ventilation differential pressure precooling provides condition.
In conclusion compared with prior art, a kind of novel goods suitable for differential pressure precooling provided by the utility model
Frame, can be when using the Forced Air Pre-cooling Mode of vertical ventilation, horizontal clamping shelf, so that the arbitrary neighborhood placed on shelf
Two packing cases between there is no lateral gap, avoid the bypass problem of air, the air for compeling to be used in pre-cooling all flows through
Venthole at left and right sides of packing case improves the pre- cold efficiency to the cargo placed in packing case, improves the effect of pre-cooling, favorably
In widely applying, it is of great practical significance.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
