[0044] The utility model discloses can carry out multiple change and can have various embodiment, thus want to illustrate each specific embodiment in the drawing and carry out the explanation to it. But this is not to limit the present application in the specific implementation, and should be understood as including all changes, equivalents and even substitutes falling within the idea and technical scope of the present application.

[0045] As Figure 1 The utility model discloses a prevent clamping hand device for double -deck transfer flatcar, install on medical split -type double -deck bed, limit the displacement between inner bed body and outer bed body, it contains first clamping piece 100, second clamping piece 200 and adjustable intermediate connecting piece 300.

[0046] The first clamping piece 100 has the clamping part of adjustable clamping space, and is detachably fixed on the inner bed body 10.

[0047] The second clamping piece 200 has the clamping part of adjustable clamping space, and is detachably fixed on the outer bed body 20.

[0048] The adjustable intermediate connecting piece 300 is the telescopic structure of adjustable length, and one end is fixedly connected with the first clamping piece 100, and the other end is fixedly connected with the second clamping piece 200. The fixed in the paper can be welding, riveting, bonding, screwing and various conventional fixing modes.

[0049] Specifically, as Figure 1 And 2 The first clamping piece 100 (the second clamping piece 200 is consistent with its structure) includes a clamping part 110, a top rod 120 and an adjusting knob 130.

[0050] The clamping part 110 is a U-shaped structure.

[0051] The top rod 120 is a threaded rod structure, penetrates through one side of the clamping part 110, so that one end is located inside the U-shaped structure of the clamping part 110, and the other end is located outside the U-shaped structure of the clamping part 110. One end of the top rod 120 located inside the U-shaped structure has a top block 121, and the other end located outside the U-shaped structure has an adjusting knob 130 (having an internal screw structure matched with the screw rod). During use, the adjusting knob 130 is rotated to cause displacement on the top rod 120, and the top block 120 is driven to gradually approach or move away from the other inside of the U-shaped structure.

[0052] In addition, the clamping part of the clamping purpose in each example above has an anti-skid layer on the side in contact with the inner bed body / outer bed body. The anti-skid layer can be a gasket 121 with anti-skid lines or similar anti-skid structure covered on the surface.

[0053] As Figure 3As shown, it is the structure of a first clamping piece 100 (the second clamping piece 200 is consistent with its structure), which is composed of clamping A piece 110, clamping B piece 120, elastic reset piece 130 and adjusting piece 140;

[0054] Among them, clamping A piece 110 and clamping B piece 120 are connected through elastic reset piece 130, forming a U-shaped or C-shaped or circular or square semi-enclosed / fully enclosed structure, in the process of use, by adjusting the distance between clamping A piece 110 and clamping B piece 120 to achieve the effect of clamping different thicknesses of bedside clamps in it;

[0055] The adjusting piece 140 is a screw rod, which penetrates the elastic reset piece 130 and is fixed at one end with the clamping A piece 110, and the other end penetrates the clamping B piece 120, and the end has a screw adjusting knob 141 (with an internal screw structure matching the screw rod);

[0056] By rotating the adjusting knob 141, it will displace on the adjusting piece 140, driving the clamping A piece and the clamping B piece to gradually approach or move away.

[0057] As shown in Figure 1 and 4 The structure of an adjustable intermediate connecting piece 300, including connecting rod main rod 310 and connecting rod auxiliary rod 320;

[0058] The connecting rod auxiliary rod 320 is detachably sleeved in the connecting rod main rod 310;

[0059] The connecting rod main rod 310 is provided with a positioning hole 311, in order to realize different extension lengths, the positioning hole is provided with a plurality of (groups, for example: the positioning hole is arranged in pairs to improve the fixing effect) along the length direction of the connecting rod main rod 310;

[0060] The connecting rod auxiliary rod 320 is provided with an elastic protruding piece 321 (the spring behind the pressure elastic protruding piece is compressed, the elastic protruding piece is pressed into the space behind it, and when there is no external pressure, the spring behind it makes the elastic protruding piece pop out);

[0061] The size, size and position of the elastic protruding piece 321 and the positioning hole 311 are matched, the elastic protruding piece is protruding without external force, so it is just clamped in the positioning hole, realizing the mutual position fixing of the connecting rod main rod 310 and the connecting rod auxiliary rod 320, when it is needed to be collected or adjusted in length, the elastic protruding piece 321 is pushed from the outside to make it retract, so as to realize the relative position readjustment of the connecting rod main rod 310 and the connecting rod auxiliary rod 320.

[0062] Considering the possibility that the first clamping piece 100 and the second clamping piece 200 are not at the same horizontal angle, the adjustable intermediate connecting piece also has the characteristics of adjustable angle. That is, asFigure 4 As shown, the positioning holes are annularly arranged in different length directions, and there are multiple positioning holes in each length direction. Thus, the effect of both turning and limiting is achieved by rotating the secondary rod to a target angle and then making the elastic protrusions just clamped in the positioning holes corresponding to the angle.

[0063] As shown, another adjustable intermediate connecting piece 300 is provided, which includes a main rod 310, a secondary rod 320, and a sleeve 330. Figure 5

[0064] The secondary rod 320 is detachably sleeved in the main rod 310.

[0065] One end of the main rod 310 and the secondary rod 320 is provided with at least one pair of elastically flexible elastic pieces 311, and the outer surface of the elastic pieces is provided with external threads.

[0066] The sleeve 330 is provided with internal threads matched with the external threads, and is rotatably sleeved on the outer surface of the elastic pieces. Thus, in use, the sleeve is slid on the outer surface of the elastic pieces by rotating the sleeve, so as to tighten the elastic pieces and clamp the secondary rod 320 in the elastic pieces, thereby achieving adjustable limiting of the two. The inner surface of the elastic pieces is further provided with an elastically flexible anti-skid pad 312, so as to increase the sliding resistance between the secondary rod 320 and the elastic pieces.

[0067] Although the above is described based on the embodiments, this is only an example and does not limit the present application. It is clear for those skilled in the art that various modifications and applications not exemplified above can be made within the scope of the essential characteristics of the embodiments. For example, each component specifically shown in the embodiments can be modified and implemented. Moreover, various differences related to such modifications and applications should be interpreted as being included in the scope of the present application defined in the appended claims.​
