Example 1:

the portable field-operation plateau adjustable sickbed as shown in fig. 1 and 3 comprises a plurality of bed frames 1 and further comprises mounting mechanisms for mounting each bed frame 1, wherein the mounting mechanisms of two adjacent bed frames 1 are in sliding fit, so that the plurality of bed frames 1 can relatively slide to be in an overlapped or parallel state to form a contracted or expanded state of the sickbed.

The working principle is as follows:

in the embodiment, the hospital bed forms a telescopic folding hospital bed through the sliding fit between the mounting mechanisms, when the hospital bed is in a contraction state, the bed frames 1 are overlapped in the vertical direction, and when the hospital bed needs to be unfolded for use, the mounting mechanisms are slid, so that the bed frames 1 relatively slide to the limit positions, and the bed frames 1 are converted into a parallel state.

Example 2:

in this embodiment, based on embodiment 1, the structure of the mounting mechanism and the extension and retraction manner of the hospital bed are further optimized and limited.

As shown in fig. 1-4, comprises three bed frames 1, and a first mounting mechanism 2, a second mounting mechanism 3 and a third mounting mechanism 4 which are respectively used for mounting the three bed frames 1; second installation mechanism 3 is including being located the slide rail 301 of 1 both sides of bed frame respectively, slide rail 301 top surface and bottom surface are equipped with spout and lower spout respectively, first installation mechanism 2 includes the first draw runner 201 that suits with the upper spout, third installation mechanism 4 includes the second draw runner 401 that suits with the lower spout, and when the sick bed expandes and folds, first draw runner 201 and second draw runner 401 slided along opposite direction.

The sickbed in the embodiment is a simple structure formed by three bed frames 1, the middle bed frame 1 and the second mounting mechanism 3 corresponding to the middle bed frame are used as the main part of the sickbed, and the other two bed frames 1 can be unfolded by respectively sliding away from the middle bed frame 1 in opposite directions depending on the arrangement of the mounting mechanisms. Specifically, the first mounting mechanism 2 and the third mounting mechanism 4 are respectively matched with the upper surface and the lower surface of the sliding rail 301 in the second mounting mechanism 3, and the sliding fit between the mounting mechanisms is realized by utilizing the matching of the sliding groove and the sliding strip. It should be noted that, because the first sliding strip 201 and the second sliding strip 401 respectively slide along the upper sliding groove and the lower sliding groove, it can be known that the three bed frames 1 are not necessarily at the same horizontal height, on one hand, the height difference can be compensated by placing mattresses with different thicknesses on the bed frames 1, on the other hand, when the bed frame 1 in the embodiment is fixed with a mattress or elastic cloth and other similar structures to enable the hospital bed to be directly used after being unfolded, although the height difference between the sliding grooves is large, the gap between the bed frames 1 can be reduced as much as possible, and thus after the hospital bed is unfolded, the height difference on the surface of the hospital bed is small and can be ignored.

In this embodiment, preferably, in order to solve the height difference of the rear surface of the unfolded hospital bed caused by the different horizontal heights of the three bed frames 1 when they are overlapped, as shown in fig. 5 to 7, the two ends of the slide rail 301 are movably provided with the positioning blocks 6 respectively adapted to the first slide bar 201 and the second slide bar 401, and when the hospital bed is unfolded, the positioning blocks 6 are respectively matched with the ends of the first slide bar 201 and the second slide bar 401 and move in the vertical direction relative to the slide rail 301 to enable the three bed frames 1 to be located at the same horizontal height. In this embodiment, taking the matching of the first slide bar 201 and the positioning block 6 as an example, and taking the direction shown in fig. 5 as a reference, the positioning block 6 matched with the first slide bar 201 is located at the left end of the slide rail 301 and is flush with the upper chute, the first slide bar 201 slides to the left, until the first slide bar completely slides out of the upper chute, the right end of the first slide bar 201 is just matched with the positioning block 6, at this time, the positioning block 6 moves downwards, so that the left bed frame 1 and the middle bed frame 1 are at the same height, and the matching between the positioning block 6 located at the right side of the slide rail 301 and the second slide bar 401 is the same as the above, except for the difference in the moving direction of the positioning block 6. It should be noted that, in order to limit the positioning block 6 to move downwards or upwards to reach the position where the bed frames 1 are flush, two ends of the slide rail 301 should be respectively provided with a blocking structure for limiting the displacement of the positioning block 6. It should be noted that the present solution is more suitable for the case that the hospital bed can be used directly after being unfolded, therefore, the bed frame 1 in the present solution can refer to the structure including the devices such as the mattress as shown in fig. 8-9. On the basis of the preferred embodiment, when the bed frame 1 is actually configured to include a mattress, so that the hospital bed in the present application can be directly used after being unfolded, according to the use requirements and the scheme that can be realized by the skilled person according to the prior art, a pillow is further disposed on the bed frame 1, and the pillow can adopt an inflatable or foldable sponge type, so that the pillow can also perform volume reduction treatment along with the contraction of the hospital bed, and the hospital bed can also be inflated or deformed for use when in use, thereby ensuring the portability of the hospital bed itself.

In addition, in the present embodiment, in order to optimize the connection between the positioning block 6 and the slide rail 301, as shown in fig. 6, the positioning block 6 and the slide rail 301 are connected by a spring 7, and the axis of the spring 7 is parallel to the moving direction of the positioning block 6. As shown in fig. 6, the spring 7 is disposed on the side of the positioning block 6 that is away from and close to the slide rail 301 during the moving process, which not only ensures the connection between the positioning block 6 and the slide rail 301, but also provides power for driving the positioning block 6 to reset, where the reset is preferably the position where the positioning block 6 and the chute are flush when the hospital bed is in a folded state, and under this condition, when the hospital bed is changed from a retracted state to an extended state, the first slide bar 201 and the second slide bar 401 are matched with the positioning block 6 during the moving process, and after the hospital bed is extended, the positioning block 6 moves to a corresponding position and remains fixed under the pressure of the first mounting mechanism 2 or under the action of the other limiting mechanisms 8.

In the present embodiment, in order to reduce the sliding resistance of the first slide bar 201 and the second slide bar 401 relative to the slide rail 301, as shown in fig. 4, rollers that are surface-fitted to the first slide bar 201 and the second slide bar 401 are respectively disposed in the upper slide groove and the lower slide groove.

Example 3:

on the basis of any one of the above embodiments, the present embodiment is further optimized and defined.

As shown in fig. 3, the first mounting mechanism 2 further includes an extending portion 202 extending along a length direction of the first slide 201, and a holding groove 203 is hollowed out on a surface of the extending portion 202.

Meanwhile, as shown in fig. 1-2, the bed further comprises a supporting mechanism arranged at the bottom of the mounting mechanism, wherein the supporting mechanism comprises a mounting seat fixedly connected with the mounting mechanism and a bed foot 5 hinged to the mounting seat. The bed legs 5 which are hinged are convenient to change along with the contraction or the expansion of the sickbed, and the minimum space occupation of the sickbed when the sickbed is contracted is ensured. Similar to the hinged mounting of the bed legs 5, other accessory mechanisms that are associated with the hospital bed in the present application may also be movably connected to the mounting mechanism in the hospital bed in a hinged manner, for example, a bracket for hanging an infusion bottle may be hinged to the surface of the first mounting mechanism or the surface of the upper extension 202 of the first mounting mechanism, and when the hospital bed is retracted, the bracket is rotated to a position that is attached to the surface of the mounting mechanism, and when the hospital bed is extended for use, the bracket is rotated to a position that is perpendicular to the surface of the mounting mechanism.

In addition, in order to further optimize the connection between the installation mechanisms, the hospital bed is changed from an unfolded state to a folded state, and the hospital bed is ensured to be in the folded state, and when the hospital bed is folded, magnetic attraction mechanisms are arranged at the positions, contacted with the end parts of the first sliding strip 201 and the second sliding strip 401, on the sliding rail 301. The magnetic attraction mechanism in this embodiment is used to keep the first slider 201 and the slide rail 301 and the second slider 401 and the slide rail 301 fixed when the hospital bed is contracted, taking the cooperation of the first slider 201 and the slide rail 301 as an example, when the hospital bed is changed from the expanded state to the contracted state, the one end of the first slider 201 and the one end of the slide rail 301 change from the farthest distance to the mutual contact, the magnetic attraction mechanism in this embodiment is disposed at two positions that are finally in mutual contact, and the fixation between the first slider 201 and the slide rail 301, that is, the fixation between the first mounting mechanism and the second mounting mechanism, is kept by using the mutual attraction force between the magnet and the metal or between the magnet and the magnet.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
