[0069] For ease of description, when the stretcher extension platform is installed on the stretcher 200, the movement from the tail of the stretcher toward the headrest is defined as forward movement, and the movement from the headrest toward the tail of the stretcher is defined as backward movement.

[0070] like Figure 1 As shown, the stretcher extension platform described in this embodiment includes: an extension platform support 1, which has two hanging plate frames 11, each hanging plate frame 11 corresponding to a base 12. The bottom of each hanging plate frame 11 is mounted on the corresponding base 12 via a corresponding sliding mechanism, so that the extension platform support 1 can move forward or backward relative to the two bases 12 via the two sliding mechanisms; a position locking mechanism is provided between each hanging plate frame 11 and the corresponding base 12 to lock the hanging plate frame 11 in a set position on the corresponding base 12.

[0071] like Figure 1 and Figure 2 As shown, the aforementioned extended platform support 1 consists of a top plate 14 and two hanging brackets 11 connected to both sides of the top plate 14, forming an inverted concave structure. When the extended platform is fixed to the stretcher 100 via the connector assembly 200, as... Figure 9 As shown, at this time, the space between the two hanging brackets 11 allows the patient lying on the stretcher 100 to comfortably position their legs. When it is necessary to lay the patient on the stretcher 100, the extended platform bracket 1 is moved towards the rear of the stretcher relative to the two bases 12 via two sliding mechanisms, that is, moved backward, which makes room for the patient to lie down. After the patient lies down, the extended platform bracket 1 can be moved in the opposite direction, that is, moved forward.

[0072] The position locking mechanism is structured as follows: a positioning hole is provided at a set position on the top surface of the base 12; depending on actual use, the extension platform bracket 1 has one forward movement to the desired position and one backward movement to the desired position, i.e., at least two set positions are required, therefore there are at least two positioning holes: a front positioning hole 124 and a rear positioning hole 125, as shown below.

[0074] The rear end of the hanging plate frame 11 has a ring-shaped handle 13; a positioning pin shaft 37 extends into the second vertical passage 34, one end of a connecting rope 38 is fixedly connected to the top of the positioning pin shaft 37, the other end of the connecting rope 38 sequentially passes through the second vertical passage 34, the first vertical passage 33, the corner passage 32, the horizontal passage 31, a through hole in the ring-shaped handle 13, and is fixedly connected to a pull handle 39; a compression spring 36 is sleeved on the connecting rope 38 in the second vertical passage 34, and the two ends of the compression spring 36 are respectively abutted against the step surface 331 and the top surface of the positioning pin shaft 37.

[0075] More preferably, a guide shaft 35 is fixedly arranged in the corner passage 32, the connecting rope 38 in the corner passage 32 is lapped on the outer circumferential contour of the guide shaft 35, the guide shaft 35 plays an arc guiding role when the connecting rope 38 changes from a horizontal motion track to a vertical direction motion track, and in addition, can reduce the abrasion of the connecting rope 38 at this position.

[0076] More preferably, the pull handle 39 is preferably a T-shaped pull handle 39 composed of a connecting part 391 and a gripping part 392, and the T-shaped pull handle 39 is convenient for medical staff to more reliably grip.

[0077] More preferably, the horizontal passage 31 is composed of a first horizontal passage 311 and a second horizontal passage 312, the end of the connecting rope 38 sequentially passes through the second vertical passage 34, the first vertical passage 33, the corner passage 32, the first horizontal passage 311, the second horizontal passage 312, a through hole in the ring-shaped handle 13, and is fixedly connected to the pull handle 39; the passage opening size of the first horizontal passage 311 is greater than that of the second horizontal passage 312, so that the connecting rope 38 does not touch the hole wall of the first horizontal passage 311, and the abrasion is reduced.

[0078] The present embodiment takes the locking of the bracket 1 position moved forward to a set position as an example for illustration, and in operation, the medical staff always holds the ring-shaped handle 13 and pulls the pull handle 39, so that the bottom of the positioning pin shaft 37 does not contact the base 12, as shown in Figure 6As shown, the extension platform bracket 1 is pushed to move forward relative to the base 12 through the sliding mechanism. When the extension platform bracket 1 moves to the position where the positioning pin shaft 37 is just above the front positioning hole 124, the medical staff releases the pull handle 39. At this time, the positioning pin shaft 37 extends into the front positioning hole 124 below the positioning pin shaft 37 under the elastic force of the compression spring 36, as shown in Figure 7 At the same time, the connecting rope 38 pulls the pull handle 39 to the inner ring side wall of the annular handle 13 at the through hole to lock the position of the extension platform bracket 1. At this time, the extension platform bracket 1 and the base 12 cannot move relative to each other.

[0079] The operation principle of locking the position of the extension platform bracket 1 moved backward to the set position is the same as the above-mentioned principle and operation method of locking the position of the extension platform bracket 1 moved forward to the set position. Only the moving direction of the extension platform bracket 1 is different.

[0080] As shown in Figure 8 In this embodiment, the structure of the sliding mechanism is that a slide rail 121 placed horizontally in front and back is fixedly arranged on the side wall corresponding to the base 12, and a sliding block is fixedly arranged on the bottom side wall corresponding to the hanging bracket 11 and movably arranged on the slide rail 121. The front stop block 122 and the rear stop block 123 are arranged on the side wall of the base at the slide rail 121. The area of the slide rail 121 between the front stop block 122 and the rear stop block 123 is the sliding block movement area.

[0081] The sliding block can be a long strip-shaped sliding block. At this time, the position of the front positioning hole 124 is such that when the extension platform bracket 1 moves to the position where the corresponding sliding block is located at the corresponding front stop block 122 and is blocked by the front stop block 122 and cannot continue to move forward, the positioning pin shaft 37 on the corresponding hanging bracket 11 is just above the front positioning hole 124. If the pull handle 39 is not subjected to the outward pulling force, the positioning pin shaft 37 can extend into the front positioning hole 124 under the elastic force of the compression spring 36. The position of the rear positioning hole 125 is such that when the extension platform bracket 1 moves to the position where the corresponding sliding block is located at the corresponding rear stop block 123 and is blocked by the rear stop block 123 and cannot continue to move backward, the positioning pin shaft 37 on the corresponding hanging bracket 11 is just above the rear positioning hole 125. If the pull handle 39 is not subjected to the outward pulling force, the positioning pin shaft 37 can extend into the rear positioning hole 125 under the elastic force of the compression spring 36.

[0082] The slider can also be composed of at least two segmented sliders, which are distributed at intervals. This embodiment takes the slider composed of two segmented sliders as an example for illustration. The segmented slider located at the front is defined as the front segmented slider 111, and the segmented slider located at the rear is defined as the rear segmented slider 112. At this time, the position of the front positioning hole 124 is such that when the expansion platform support 1 is moved to the corresponding front segmented slider 111 against the corresponding front stop block 122 through the two sliding mechanisms, the positioning pin shaft 37 on the corresponding hanging plate support 11 can extend into the front positioning hole 124 under the elastic force of the compression spring 36; the position of the rear positioning hole 125 is such that when the expansion platform support 1 is moved to the corresponding rear segmented slider 112 against the corresponding rear stop block 123 through the two sliding mechanisms, the positioning pin shaft 37 on the corresponding hanging plate support 11 can extend into the rear positioning hole 125 under the elastic force of the compression spring 36.

When the active element 5 swings around the corresponding hinge, the stop block 511 on the active element 5 can protrude out of the top surface 21 of the bracket body or retract into the corresponding mounting hole 23.

[0088] Here, each hinge seat 50 can be a pair of hinge supports, and the active element 5 is located between the two hinge supports and is hinged by a hinge pin. There can be two hinge pins, one on each side wall of the active element 5, and in this case, the inner side walls of the corresponding two hinge supports are pin holes. There can also be two hinge pins, one on each inner side wall of the two hinge supports, and in this case, the two side walls of the active element 5 are pin holes. There can also be one hinge pin, and a through pin hole is formed in the active element 5, and the hinge pin is inserted into the pin hole. The specific form of the hinge is not required and can be selected as appropriate.

[0089] In the embodiment, as shown in the figure, Figure 11 The active element 5 has a first swing arm 51 and a second swing arm 52, and the first swing arm 51 and the second swing arm 52 are located on both sides of the hinge of the active element 5. The first swing arm 51 has a limiting plate 53, and the stop block 511 is the end of the first swing arm 51.

[0090] A first installation groove 512 is formed in the bottom surface of the first swing arm 51, and a first spring 7 is placed in the first installation groove 512. The bottom plate 201 is encapsulated in the bottom of the bracket body, and in this case, the first spring 7 has a certain pre-tightening force. Under the action of the elastic force of the first spring 7, the two ends of the first spring 7 abut against the groove bottom of the first installation groove 512 and the bottom plate 201, respectively, and the limiting plate 53 abuts against the groove bottom of the mounting groove at the corresponding mounting hole 23, so that the stop block 511 protrudes out of the top surface 21 of the bracket body.

[0091] The bottom plate 201 can be directly fixed on the bottom surface 25 of the support body by screws. Of course, a bottom plate embedding groove 20 can be formed on the bottom surface 25 of the support body, and the bottom plate 201 can be embedded in the bottom plate embedding groove 20 and then fixed by screws, so that the bottom surface of the bottom plate 201 and the bottom surface 25 of the support body are substantially in the same plane. Figure 11 As shown in the figure, the bottom plate 201 is embedded in the bottom plate embedding groove 20 and then fixed by screws, so that the bottom surface of the bottom plate 201 and the bottom surface 25 of the support body are substantially in the same plane.

[0092] The device quick switching support 2 can be fastened on a required carrier, such as a stretcher expansion platform, a mounting bracket of an ambulance, or the like, by a bolt or screw fixing mode.

[0093] When the limiting plate 53 is pressed against the bottom of the mounting groove at the corresponding mounting hole 23 under the elastic force of the first spring 7, the part of the stop block 511 protruding out of the top surface 21 of the support body has an inclined guide plane 513. More preferably, in this state, the part of the stop block 511 protruding out of the top surface 21 of the support body has a horizontal three-prism structure, and of the two prism faces exposed on the three-prism structure, one is the inclined guide plane 513, and the other is a vertical blocking face 514.

[0094] At least one guide block 4 is arranged on the top surface 21 of the support body, and the guide block 4 has a side wall guide groove 41.

[0095] When the device quick switching support has only one mounting hole 23 and one guide block 4, the side wall guide groove 41 on the guide block 4 has two parts distributed on the two sides of the guide block 4. In this case, the device to be installed, for example, an injection pump, can be provided with a protruding stop bar and a mounting block, which can be an integrated structure or separate and independent from each other. The mounting block has two strip-shaped sliding blocks capable of being inserted into the side wall guide groove 41, respectively. The injection pump is pushed into the top surface 21 of the support body through the cooperation of the strip-shaped sliding blocks and the side wall guide groove 41, and the pushing direction is defined as the forward direction. When the stop bar contacts the guide plane 513 after being pushed into the support body, the stop bar moves relative to the guide plane 513 with the continuous forward pushing of the injection pump, and an downward force is applied to the stop block 511, forcing the stop block 511 to retract downward into the corresponding mounting hole 23. When the stop bar passes the guide plane 513, the guide plane 513 is no longer pressed by the stop bar, so that the stop block 51 is forced to extend upward out of the mounting hole 23 under the elastic force of the first spring 7 and is blocked at the stop bar. At this time, the injection pump cannot retreat, thus achieving the purpose of locking the device stably on the device quick switching support 2. After being fixed, the device will not shake or loosen, and the fixing is very firm.

[0096] The embodiment can further be provided with at least one guide slot 22 on the top surface 21 of the bracket body. A guide strip is additionally provided on the equipment to be installed and cooperates with the guide slot 22. The equipment can be quickly positioned and located by cooperation of the guide strip and the guide slot 22.

[0097] The optimal scheme is to design the bracket body as a cuboid structure. The number of the mounting holes 23, the guide slots 22 and the guide blocks 4 is two, and the two mounting holes 23, the two guide slots 22 and the two guide blocks 4 are symmetrically distributed relative to the center line of the long side of the bracket body. The two guide slots 22 are located inside the two mounting holes 23, and the two guide blocks 4 are located inside the two guide slots 22. The side wall guide slot 41 on the guide block 4 is provided with one slot, and the two side wall guide slots 41 on the two guide blocks 4 can be oppositely arranged or oppositely arranged. The working principle is the same as that of the above-mentioned mounting hole 23 and guide block 4. Here, it is not repeated. Embodiment three

[0098] The embodiment is designed for the stop block position adjusting mechanism on the basis of embodiment two.

[0099] As shown in Figure 11 , when the limiting plate 53 is abutted on the bottom of the mounting slot corresponding to the mounting hole 23 under the elastic force of the first spring 7, at this time, the bottom surface 521 of the second swing arm is an upwardly inclined guide plane from the corresponding hinge to the end 522 of the second swing arm. The guide plane and the bottom plate 201 form a triangular space 54.

[0100] As shown in Figure 11 and Figure 12 , the structure of the stop block position adjusting mechanism in the embodiment is that an adjusting hole 24 is formed in the side wall of the bracket body, and the adjusting hole 24 penetrates the side wall of the mounting slot. An active adjusting member 6 is arranged in the mounting slot, and the active adjusting member 6 has a pressing plate 62 penetrating the adjusting hole 24 and at least one push rod 61. The number of the push rod 61 is consistent with the number of the active member 5 and one-to-one corresponds in position. The end of the push rod 61 has an inclined inclined plane or an arc-shaped curved surface 611.

[0101] The working principle of the above-mentioned stop block position adjusting mechanism is as follows:

[0102] When the push plate 62 is pushed inwards, the end of each push rod 61 will extend into the triangular space 54 between the corresponding movable member 6 and the bottom plate 201. After the inclined plane or arc surface 611 of the end of the push rod 61 contacts the guide plane, when the push plate 62 is continuously pushed inwards, each push rod 61 will force the corresponding second swing arm 52 to swing upwards around the corresponding hinge, and at the same time, the corresponding first swing arm 51 will swing downwards around the corresponding hinge against the elastic force of the first spring 7, so that the stopper 511 on each movable member 5 will retract into the mounting hole 23 synchronously.

[0103] Conversely, when the push plate 62 is pulled outwards, each push rod 61 will gradually move towards the opening direction of the corresponding triangular space 54, until the inclined plane or arc surface 611 of the end of the push rod 61 no longer contacts the guide plane, at which time each push rod 61 will no longer interfere with the corresponding movable member 5, and each movable member 5 will swing upwards around the corresponding hinge under the elastic force of the corresponding first spring 7, so that the corresponding stopper 511 will return to the position protruding out of the top surface 21 of the bracket body.

[0104] In order to guide the moving direction of the movable adjusting member 6, the mounting slot in the embodiment is designed as a structure composed of a first mounting slot 27 and at least one second mounting slot 26, and each second mounting slot 26 is provided with one movable member 5 and the corresponding hinge seat 50, and the second mounting slot 26 is communicated with the first mounting slot 27 through a guide slot 28.

[0105] The movable adjusting member 6 is located in the first mounting slot 27, the adjusting hole 24 penetrates the side wall of the first mounting slot 27, and each push rod 61 is respectively inserted into the corresponding guide slot 28, at which time each guide slot 28 plays a role of guiding the corresponding push rod 62.

[0106] In the embodiment, a reset mechanism can also be provided, which enables the push plate 62 to automatically return to protrude out of the side wall of the bracket body after the pressing force is released, such as Figure 12As shown, the structure of the reset mechanism in this embodiment is that a second installation groove 29 is formed on the bracket body, the second installation groove 29 penetrates the side wall of the first installation groove 27, a second spring 8 is placed in the second installation groove 29, the second spring 8 has a certain pre-tightening force, when the pressing plate 62 is not under the pressing force, the two ends of the second spring 8 are respectively against the side wall of the second installation groove 29 and the movable adjusting piece 6, the movable adjusting piece 6 is against the side wall of the installation groove 27 on the side of the adjusting hole 24, and the pressing plate 62 protrudes out of the side wall of the bracket body, at this time, each push rod 62 does not interfere with the corresponding movable piece 5, and the corresponding stop block 511 on each movable piece 5 is located at the position protruding out of the top surface 21 of the bracket body. When a pressing force that can overcome the second spring 8 is applied to the pressing plate 62, each push rod 61 will force the corresponding second swing arm 52 to swing upward around the corresponding hinge, at this time, the corresponding first swing arm 51 will swing downward around the corresponding hinge against the elastic force of the first spring 8, so that the stop block 511 on the movable piece 5 is retracted into the installation hole 23 at the same time, at this time, the device can be quickly and smoothly unlocked and removed from the device quick adapter bracket.
