Description

Technical Field

[0001] This invention belongs to the field of modular hospital equipment technology, specifically relating to a modular hospital end plate linkage side wall translation and expansion mechanism. Background Technology

[0002] The aforementioned modular shelters are similar to shipping containers, and their standards are also based on container standards. Depending on the needs, different equipment and devices are loaded. Compared to shipping containers, modular shelters offer higher reliability, electromagnetic compatibility, airtightness, and thermal insulation. However, currently, modular shelters lack good expandability; the shelter itself cannot be quickly extended, resulting in low space utilization and failing to meet the needs of various situations. Therefore, most modular shelters are currently equipped with expansion structures to expand their space. Existing military and civilian expandable shelters generally adopt a drawer-type expansion structure, that is, an integral telescopic expansion compartment is set within the shelter body, using electric or hydraulic drive methods to push the expansion compartment outward for expansion. However, since the width of traditional modular containers is the same as that of standard shipping containers, the usable space inside the modular container is quite small. Most of the existing telescopic extension modules are set inside the modular container, and the width of the modular container is strictly limited by the width of the transport vehicle. Therefore, the telescopic extension modules will greatly encroach on the usable space inside the modular container, resulting in weak functionality. At the same time, the assembly of some existing telescopic modular containers on the market requires a lot of work, which is time-consuming and labor-intensive, and the subsequent storage is complicated, with the disadvantage that it is not possible to hide and store them quickly.

[0003] Therefore, it is necessary to make reasonable improvements to the existing modular shelter expansion mechanism. To this end, the applicant has developed a beneficial design, and the technical solution described below arises from this context. Summary of the Invention

[0004] The purpose of this invention is to provide a compact and stable side-wall translational extension mechanism for a container that helps to eliminate the need for an integral telescopic cabin extension structure, thereby effectively reducing the space occupied by the extension structure in the main cabin when the container is folded up, thus improving the functionality of the container and facilitating convenient and efficient deployment and folding.

[0005] The objective of this invention is achieved as follows: a side panel sliding and expanding mechanism for a modular shelter includes a frame, two flaps, multiple power cylinders, an expanding side panel, and a pair of linked end plates. The frame has a pair of longitudinal frame beams on its left and right sides and transverse frame beams on its upper and lower sides. The pair of flaps have identical structures and are respectively hinged to the transverse frame beams on the upper and lower sides of the frame, and both flaps can be retracted to a vertical position or extended outwards to a horizontal position. The multiple power cylinders are connected between the two flaps and the frame. The power cylinder can drive the flap to flip it outward; the extended side plate is vertically arranged, and an extended side plate guide pulley is connected to the upper and lower ends of the long sides of the left and right sides of the extended side plate. Extended guide rails that can slide with the extended side plate guide pulleys are connected to the flap, near the left and right ends respectively; the two linkage end plates are arranged between the transverse frame beams on the upper and lower sides of the frame body, and one long side of each linkage end plate is hinged to the left and right ends of the extended side plate respectively. The linkage end plates are located away from the extended side plate. A linkage end plate pulley is installed at both the upper and lower ends of one long side of the structure. Slide grooves, matching the shape of the linkage end plate pulleys and extending laterally, are formed on the two transverse frame beams. The container end plate linkage side enclosure translational expansion mechanism has a retracted state and an extended state. In the retracted state, both flaps retract to a vertical position, and the expansion guide rail also remains vertical. The expanded side plate is retracted into the space between the two flaps and the frame body, while the two linkage end plates and the expanded side plate remain parallel. The linkage end plate pulleys are located in the slide grooves away from the longitudinal frame beams. At the position; in the unfolded state, the two flaps are flipped to a horizontal state and the extension guide rail is also kept horizontal. The extension side plate guide pulley of the extension side plate can slide on the extension guide rail in the horizontal state and make the extension side plate move away from the frame in the horizontal direction. At the same time, the linkage end plate pulleys of the two sides can slide in the slide groove. When the extension side plate slides to the limited preset position of the extension guide rail, the two sides linkage end plates can maintain a preset vertical angle with the extension side plate, and the linkage end plate pulley is located in the slide groove near the longitudinal frame beam.

[0006] In a specific embodiment of the present invention, the power cylinder includes a power cylinder body and a power cylinder piston rod passing through the power cylinder body, the power cylinder piston rod being capable of reciprocating within the power cylinder body; a longitudinal frame beam connecting seat is fixedly installed on each of the two longitudinal frame beams at a position corresponding to the power cylinder body, and a flap connecting seat is fixedly installed on each of the two flap plates at a position corresponding to the piston rods of the two sides; the tail end of the power cylinder body is pivotally connected to the longitudinal frame beam connecting seat, thereby achieving a hinge between the power cylinder body and the longitudinal frame beams; the end of the power cylinder piston rod away from the power cylinder body is also pivotally connected to the flap connecting seat, thereby achieving a hinge between the power cylinder piston rod and the flap body.

[0007] In another specific embodiment of the present invention, a hinged flap is connected to the long side of the two flaps near the transverse frame beams, and the two flaps and the two transverse frame beams are pivotally connected together by the hinged flap.

[0008] In another specific embodiment of the present invention, an extension side plate positioning plate is connected to the left and right edges of the extension side plate, and an extension side plate hinge is installed on both extension side plate positioning plates. The two linkage end plates are hinged to the extension side plate body through the extension side plate hinge.

[0009] In another specific embodiment of the present invention, the extended guide rail has an internal guide rail guide groove with an opening facing the corresponding extended side plate guide pulley. The guide rail guide groove is adapted to the shape of the extended side plate guide pulley, and the extended side plate guide pulley is slidably connected to the guide rail guide groove.

[0010] In another specific embodiment of the present invention, one end of the extended guide rail along the length direction is pivotally connected to the longitudinal frame beam, while the other end of the extended guide rail along the length direction is also connected to an extended guide rail positioning seat, which is fixedly installed on the flip plate body to realize the connection between the extended guide rail and the flip plate body.

[0011] In a further specific embodiment of the present invention, an extension guide rail limiting groove is also provided on the extension guide rail. The extension guide rail limiting groove extends parallel to the length direction of the extension guide rail body. The extension guide rail positioning seat is connected to the extension guide rail limiting groove by fasteners and can adjust its fixed position within the extension guide rail limiting groove.

[0012] In a further specific embodiment of the present invention, the pair of longitudinal frame beams and the pair of transverse frame beams of the frame body are both tubular truss structures with triangular units.

[0013] In yet another specific embodiment of the present invention, a plurality of extended side panel working windows are provided on the extended side panel.

[0014] The technical advantages of the present invention are as follows: First, the modular cabin end-plate linkage side-wall translational expansion mechanism of the present invention can meet the usage requirements of modular cabins in various occasions, and has the characteristics of good structural stability, smooth and reliable expansion and retraction process, good sealing performance, etc., and facilitates the expansion of its own space; Second, this expansion structure can be set at the end position of the modular cabin body in a parallel structure with one or more of them, and the top and bottom panels of the expansion space are formed by the flip plates on the upper and lower sides, respectively. The expansion side plates and the linkage end plates on both sides can simply and efficiently form the side panels and front and rear panels of the expansion space, thereby realizing the construction of a closed expansion space, and can eliminate the expansion structure of the integral telescopic cabin. It can also significantly reduce the occupation of the internal space of the modular cabin body in the retracted state. The overall structure is simple and compact, and can quickly and conveniently expand the internal space of the modular cabin body to meet various needs. The design meets the needs of the mobile cabin and enhances its functionality. In situations requiring cabin retraction, such as during transport, the cabin can be easily and conveniently folded up to meet the standard dimensions required by transport vehicles and other operations, ensuring safety during work and transportation and adapting to various usage scenarios. Thirdly, the push-panel type extension side panels and the connection between the two side linkage end panels and the frame are simple and reliable, improving user comfort while effectively reducing assembly and installation difficulty. When fully extended, the internal space of the extension structure is completely connected to the internal space of the main cabin without being separated. It can also be quickly and efficiently unfolded, effectively improving comfort. When folding up, simply move the extension side panels inward, and the linkage end panels will fold up accordingly. Folding up the flaps then converts the cabin to its folded state, making operation very convenient and flexible. Attached Figure Description

[0021] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of the present invention should be considered within the scope of protection of the present invention.

[0022] In the following description, all directional (or orientational) concepts involving up, down, left, right, front, and back refer to the position of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be construed as a special limitation on the technical solution provided by this invention.

[0023] Please see Figures 1 to 5 This paper illustrates a side-mounted sliding expansion mechanism for a modular shelter, comprising a frame 1, two flaps 2, multiple power cylinders 3, an expansion side plate 4, and a pair of linked end plates 5. The frame 1 is a rectangular steel frame structure, which effectively ensures the flatness and strength requirements of the shelter. The frame 1 also includes a pair of longitudinal frame beams 11 forming its left and right sides, and transverse frame beams 12 forming its upper and lower sides. Please refer to [link to relevant documentation]. Figure 1 and Figure 2The pair of flaps 2 have identical structures and are respectively hinged to the transverse frame beams 12 on the upper and lower sides of the frame body 1. Both flaps 2 can be retracted to a vertical state or extended outward to a horizontal state. There are four power cylinders 3, which are connected in pairs between the two flaps 2 and the frame body 1. The power cylinders 3 can push the flaps 2 to flip them outward. The extension side plate 4 is vertically arranged, and an extension side plate guide pulley 41 is connected to the upper and lower ends of the long sides of the left and right sides of the extension side plate 4. The flaps 2 are connected to the extension side plate guide pulleys 41 near the left and right ends, respectively, so as to slide with the extension side plate guide pulleys 41. The expansion guide rail 21 is matched; and the two linkage end plates 5 are arranged between the transverse frame beams 12 on the upper and lower sides of the frame body 1, and the long side of one side of the two linkage end plates 5 is respectively hinged to the left and right ends of the expansion side plate 4. A linkage end plate pulley 51 is installed at the upper and lower ends of the long side of the two linkage end plates 5 away from the expansion side plate 4. The two transverse frame beams 12 are respectively formed with a sliding groove 121 that matches the shape of the linkage end plate pulley 51 and extends laterally. The sliding groove 121 is parallel to the length direction of the transverse frame beam 12. The linkage end plate pulley 51 can slide in the sliding groove 121 and guide the retraction and expansion of the linkage end plate 51.

[0024] In this embodiment, the modular cabin end plate linkage side panel translational expansion mechanism has a retracted state and an extended state. In the retracted state, both flaps 2 are retracted to a vertical state, and the extension guide rail 21 is also kept vertical. The extended side plate 4 is retracted into the space between the two flaps 2 and the frame body 1, while the two linkage end plates 5 and the extended side plate 4 remain parallel to each other. The linkage end plate pulley 51 is located in the slide groove 121 away from the longitudinal frame beam 11. In the extended state, the two flaps 2 are flipped to a horizontal state, and the extension guide rail 21 is also kept horizontal. The extended side plate guide pulley 41 of the extended side plate 4 can slide on the horizontal extension guide rail 21, allowing the extended side plate to... 4. The extension side plate moves away from the frame 1 in the horizontal direction. At the same time, the linkage end plate pulleys 51 of the linkage end plates 5 on both sides can slide in the slide groove 121. When the extension side plate 4 slides to the limited preset position of the extension guide rail 21, the linkage end plates 5 on both sides can maintain a preset vertical angle with the extension side plate 4. The linkage end plate pulleys 51 are located in the slide groove 121 near the longitudinal frame beam 11. At this time, the flip plates 2 on the upper and lower sides constitute the top panel and bottom panel of the extension space. The moved extension side plate 4 and the linkage end plates 5 on both sides together constitute the side panel and front and rear panel of the extension space, realizing the final extension of the extension mechanism, completing the increase and expansion of the cabin space, and making full use of both the main cabin and the extension space after the expansion.

[0025] Please continue reading Figure 1 and Figure 2 And can be combined Figure 4 The power cylinder 3 includes a power cylinder body 31 and a power cylinder piston rod 32 passing through the power cylinder body 31. The power cylinder piston rod 32 can reciprocate within the power cylinder body 31. A longitudinal frame beam connecting seat 111 is fixedly installed on each of the two longitudinal frame beams 11 at a position corresponding to the power cylinder body 31. A flap connecting seat 22 is fixedly installed on each of the two flaps 2 at a position corresponding to the power cylinder piston rods 32 on both sides. The tail end of the power cylinder body 31 is pivotally connected to the longitudinal frame beam connecting seat 111, thereby achieving a hinge between the power cylinder body 31 and the longitudinal frame beams 11. The end of the power cylinder piston rod 32 away from the power cylinder body 31 is also pivotally connected to the flap connecting seat 22, thereby achieving a hinge between the power cylinder piston rod 32 and the flap 2 body. The power cylinder 3 can not only provide sufficient support for the flaps 2, but also reduce the weight of the mechanism. When folding or expanding, no high-power electric drive is required.

[0026] Furthermore, a hinged flap 23 is connected to the long side of the two flaps 2 near the transverse frame beam 12, and the two flaps 2 are pivotally connected to the transverse frame beam 12 through the hinged flap 23; and an extension side plate positioning plate 42 is connected to the left and right edges of the extension side plate 4, and an extension side plate hinged flap 43 is installed on the two extension side plate positioning plates 42, and the two linkage end plates 5 are hinged to the extension side plate 4 body through the extension side plate hinged flap 43. In this embodiment, the specific connection method between the linkage end plates 5 on both sides and the extension side plate 4 is not limited in any way, and any structural changes are within the protection scope of this patent, and will not be described in detail here.

[0027] Furthermore, the extended guide rail 21 has an internal guide rail groove 211 with an opening facing the corresponding extended side plate guide pulley 41. The guide rail groove 211 is adapted to the shape of the extended side plate guide pulley 41, and the extended side plate guide pulley 41 slides in cooperation with the guide rail groove 211, and the extended side plate guide pulley 41 can also be in the guide rail groove 211.

[0028] Preferably, one end of the extended guide rail 21 is pivotally connected to the longitudinal frame beam 11 along its length, while an extended guide rail positioning seat 212 is connected to the other end of the extended guide rail 21 along its length. The extended guide rail positioning seat 212 is fixedly installed on the flip plate 2 body to realize the connection between the extended guide rail 21 and the flip plate 2 body.

[0029] Please see Figure 5An extension guide rail limiting groove 213 is also provided on the extension guide rail 21. The extension guide rail limiting groove 213 extends parallel to the length direction of the extension guide rail 21 body. The extension guide rail positioning seat 212 is connected to the extension guide rail limiting groove 213 by fasteners and can adjust its fixed position in the extension guide rail limiting groove 213. By adjusting the position of the extension guide rail positioning seat 212, the extension length of the extension side plate 4 can be controlled, so that the size of the extension space formed by the extension compartment can meet various different usage needs.

[0030] Please continue reading Figure 1 and Figure 2 The pair of longitudinal frame beams 11 and the pair of transverse frame beams 12 of the frame body 1 are both tubular truss structures with triangular units. This structure is stable and reliable and can effectively improve the strength.

[0031] Preferably, a plurality of extended side panel working windows 44 are provided on the extended side panel 4; Figure 1 The diagram shows three windows, which can be opened to enable ventilation and ensure a clear view of the container, meeting its usage needs in specific environments.

[0032] Please see Figures 1 to 5 The applicant briefly describes the working principle of the technical solution provided by this invention: When the end plate linkage side wall translation expansion mechanism is in the retracted state, i.e., stored at one side of the container body, as... Figure 3 As shown, at this time, the extended side plate 4 is positioned close to the frame 1, while the upper and lower flaps 2 are retracted to a vertical position and close to the outer side of the extended side plate 4. The linkage end plates 5 on both sides are folded and pressed against the inner side of the extended side plate 4 in a parallel state. In this retracted state, the extended side plate 4, the two flaps 2 on the upper and lower sides, and the linkage end plates 5 form a simple and compact folding structure. The components are tightly connected, and the footprint is small. When the vehicle is parked and the extension mechanism needs to be extended, the upper and lower flaps 2 must first be flipped open. At this time, the operation control system causes the four power cylinders 3 to start working and push the upper and lower flaps 2 outwards respectively. Figure 2As shown, the upper flap 2 rotates upward 90 degrees to a preset upper position using the flap hinge 23 as the rotation axis and remains horizontal. Similarly, the lower flap 2 rotates downward 90 degrees to a preset lower position using the flap hinge 23 as the rotation axis and remains horizontal. At this time, the upper and lower flaps 2 respectively constitute the top and bottom panels of the extended space. Simultaneously, the extension guide rails 21 on both flaps 2 rotate to a horizontal position, and the extension side plate guide pulleys 41 on the extension side plate 4 can slide on the extension guide rails 21, allowing the extension side plate 4 to move outwards. When the extension side plate guide pulleys 41 slide to the far end of the extension guide rail 21, the extension side plate 4 moves to the preset extension position. During this process, the linkage end plate pulleys 51 of the two linkage end plates 5 hinged to the extension side plate 4 slide within the slide groove 121 and unfold towards the longitudinal frame beam 11. When it moves to the limit end, as... Figure 2 and Figure 4 As shown, at this time, the linkage end plates 5 on both sides and the extension side plates 4 maintain a preset vertical angle and form the front and rear end plates of the extension space. Finally, the extension mechanism can be extended to meet the working requirements inside the container and can demonstrate good sealing performance, achieving quick and efficient operation and improving the efficiency of the extension work. When it is necessary to retract the extension mechanism, simply reverse the operation to move the extension side plates 4 inward and rotate the upper and lower flip plates 2 inward, which is convenient for transportation and storage and is simple and quick to operate.

[0033] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
