Description

Technical Field

[0001] The present invention relates to the fields of natural disaster accident rescue, mass casualty treatment during war, infectious disease prevention and control, nuclear, chemical and biological first aid, etc., and particularly relates to a passage cabin. Background Art

[0002] Since the 1990s, China has started to research and apply mobile cabin hospitals, which are mainly used for emergency disaster rescue and are equipped in military medical support institutions, playing an important role in emergency medical rescues such as earthquakes.

[0003] However, so far, the national emergency medical rescue teams and local government medical rescue institutions in China still mainly use vehicle-mounted hospitals. At present, some hospitals used in medical rescues only use box-type vehicles, which are not mobile cabin hospitals in the strict sense and are inconvenient to expand to form a semi-fixed permanent hospital for medical treatment.

[0004] Moreover, traditional mobile cabins cannot form standardized products, and it is difficult to mass-produce them; since the main transportation carrier of mobile cabin hospitals is land transportation, the time required to transport them to the medical treatment site is relatively long, and the medical function of quickly treating the wounded cannot be realized in a short time; the products are lacking in terms of environmental adaptability, etc., and are inconvenient to deploy on-site or often cannot achieve the desired effect.

[0005] Existing passage cabins mainly adopt the combination of non-standard cabins + skeleton tents. The overall expansion and retraction of the passage cabin are rather troublesome, and the heat preservation performance of the skeleton tent is poor. The docking distance between the passage cabin and the functional cabin is not adjustable, resulting in difficulty in modular splicing between the passage cabin and the functional cabin.

[0006] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of implication that this information constitutes prior art already known to those of ordinary skill in the art.

[0077] Multiple shock absorbers are provided between the important equipment inside the cabin and the bottom plate of the cabin body 1. Preferably, four groups of shock absorbers are provided between each piece of equipment and the bottom plate of the shelter. The shock absorber is provided with a longitudinal shock absorption device, such as Figure 19 , Figure 20 shown. The longitudinal shock absorption device includes an upper base body 603 connected to the equipment and a lower base body 605 connected to the bottom plate of the shelter. The upper base body 603 is composed of a cover plate and a cover plate cylinder connected to the cover plate. Inside the cover plate cylinder, a damping rod 606 connected to the cover plate is provided. The damping rod 606 is provided with a damping inclined surface for friction energy dissipation at the free end. The lower base body 605 is composed of a bottom plate, a first bottom plate cylinder and a second bottom plate cylinder connected to the bottom plate. Inside the lower end of the second bottom plate cylinder, a radial stepped blind hole is provided, and a stepped shaft 607 is provided in the hole. The end with a smaller outer diameter of the stepped shaft 607 is far from the hole opening, and a damping spring 608 is sleeved outside it. At the lower position of the other end, a bevel structure adapted to the damping inclined surface is provided, and an arc surface structure adapted to the rod contour of the damping rod 606 is provided on the end surface. A shock absorption spring 602 is embedded inside the cover plate cylinder and the first bottom plate cylinder. The length of the shock absorption spring 602 is greater than the height of the second bottom plate cylinder. During use, when the transport vehicle generates longitudinal bumps, the cover plate of the upper base body 603 is compressed downward by the force, and due to the action of the shock absorption spring 602, the downward impact will be alleviated and energy will be stored. At the same time, the damping spring 608 pushes one end of the stepped shaft 607 to slide relatively along the damping inclined surface of the damping rod 606. After the end of it contacts the rod part of the damping rod 606, the arc surface structure provided at the end of the stepped shaft 607 that is adapted to the rod contour of the damping rod 606 slides along the damping rod 606 for sliding guidance. When the shock absorption spring 602 reaches the maximum compression amount under the action of this impact and rebounds upward, after the end bevel structure of the stepped shaft 607 contacts the damping inclined surface of the damping rod 606, due to the action of the damping spring 608, a frictional force is generated between the damping inclined surface at the bottom of the damping rod 606 and the bevel surface at the end of the stepped shaft 607, and the energy is consumed through frictional work, and at the same time, the upward impact force generated when the shock absorption spring 602 rebounds is alleviated. The number of damping inclined surfaces provided at the bottom of the damping rod 606, the number of stepped shafts 607 and damping springs 608 that cooperate with the damping inclined surface, as well as the bevel angle, height, material friction coefficient, etc. can be specifically selected according to the weight of the equipment and the bump limit to be borne to meet different use requirements.

[0078] The shock absorber is also provided with a transverse shock absorption device, such as Figure 20As shown in the figure, the lateral shock absorber is composed of more than two shock-absorbing tiles 601 arranged under the cover plate. The shock-absorbing tiles 601 are circumferentially distributed around the center of the cover plate. The shock-absorbing tile 601 is an arc-shaped structure with an opening facing outwards. One end of it is fixedly connected to the bottom of the cover plate, and the other end is provided with an arc surface that is adapted to and abuts against the inner wall of the second bottom plate cylinder of the lower base 605 under normal conditions. Preferably, the shock-absorbing tile 601 is made of mild steel. When in use, when the vehicle brakes suddenly or turns, causing lateral bumps, the cover plate of the upper base 603 connected to the equipment will drive the shock-absorbing tile 601 to generate an impact in the corresponding direction. The free end of the arc-shaped shock-absorbing tile 601 will press against the inner wall of the second bottom plate cylinder and deform, thereby absorbing and alleviating the impact force. Since multiple shock-absorbing tiles 601 are circumferentially distributed, the impact force can be alleviated and shock-absorbed in multiple directions, realizing the function of lateral shock protection for precision equipment during transportation.

[0079] The shock absorber is provided with a leveling device, such as Figure 21 As shown in the figure, the leveling device is composed of a height-adjusting cylinder 604, a positioning gear ring 611, and a combination of a slide bar 610 and a slide groove 609. The height-adjusting cylinder 604 is provided with internal threads, and the outer wall of the first bottom plate cylinder of the lower base 605 is provided with external threads that are adapted to and connected to it. The positioning gear ring 611 is arranged on the upper surface of the bottom plate. The slide groove 609 and the slide bar 610 are arranged on the outer wall of the height-adjusting cylinder 604. Among them, the combination of the slide bar 610 and the slide groove 609 is not less than two groups, and at least one group of the circumferential spacing along the positioning gear ring 611 is the sum of an integer multiple of the tooth pitch of the positioning gear ring 611 and half a tooth pitch. The lower end of the slide bar 610 is provided with a tooth-shaped structure adapted to the positioning gear ring 611, and the upper end is provided with sliding pins on both sides. The middle part of the slide groove 609 is an empty groove structure along the axial direction of the height-adjusting cylinder 604. The upper and lower parts of the slide groove 609 are respectively connected to the outer wall of the height-adjusting cylinder 604, and the lower part is an open structure. A space for the sliding pins to move up and down is provided between both sides of the slide groove 609 and the outer wall of the height-adjusting cylinder 604. The slide bar 610 is magnetically connected to the height-adjusting cylinder 604. In this embodiment, two groups of combinations of the slide bar 610 and the slide groove 609 are preferably set. During the use process, when the equipment needs to be adjusted to a higher height, the slide bar 610 magnetically adsorbed on the height-adjusting cylinder 604 can be rotated around the sliding pin and unfolded, and the height-adjusting cylinder 604 can be rotated with the slide bar 610 as a wrench, as Figure 22 As shown in the figure, the height-adjusting cylinder 604 is rotated to the top to shield the function of the shock-absorbing spring 602, and adjusted to an appropriate height position according to specific conditions. Then, the slide bar 610 is moved downward and received into the slide groove 609, and the tooth-shaped structure at the lower end of the slide bar 610 is abutted against the gear ring. Since the circumferential spacing of the two groups of the slide bar 610 and the slide groove 609 is the sum of an integer multiple of the tooth pitch of the positioning gear ring 611 and half a tooth pitch, after the first stop slide bar 6101 and the second stop slide bar 6102 abut against the positioning gear ring 611, as Figure 23, as shown in Figure 24, it abuts against the left tooth surface and the right tooth surface of the corresponding position gear ring respectively. As a special position situation, a single sliding bar 610 can also abut against the gear ring at the left and right surfaces of its tooth profile simultaneously for limit and stop. In this way, the height-adjusting cylinder 604 is stopped by the cooperation of the tooth profile structure at the bottom of the sliding bar 610 and the positioning gear ring 611 in both the clockwise and counterclockwise directions. At the same time, after being received into the sliding groove 609, the first stop sliding bar 6101 and the second stop sliding bar 6102 are magnetically attracted to the outer wall of the height-adjusting cylinder 604. When transfer transportation is required, the height-adjusting cylinder 604 is rotated to the lower part to release the buffer and shock-absorbing function of the shock-absorbing spring 602 again.
