Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The present invention provides Figure 1-7 A weighing device is shown, comprising a weighing structure 100, wherein a load-bearing mechanism 200 is arranged above the weighing structure 100, the load-bearing mechanism 200 comprises a first support plate 201, a movable leg 204 and a load-bearing plate 205, a support leg 203 is symmetrically hinged at the bottom end of the first support plate 201, a second support plate 202 is fixedly arranged above the first support plate 201, a third support plate 207 is fixedly arranged above the second support plate 202, the ends of the bottom ends of the third support plate 207 are fixedly arranged with grooves, the ends of the second support plates 202 are threadedly connected with bolts, the movable legs 204 are movably arranged on the side opposite to the support legs 203, and the movable legs 204 are hinged to the bottom end of the first support plate 201, the load-bearing plate 205 is fixedly arranged above the weighing structure 100, a shift rod 206 is symmetrically arranged between the load-bearing plate 205 and the weighing structure 100, and the load-bearing plate 205 and the shift rod 206 are used for supporting the movable legs 204 after rotation.

[0043] Specific reference Figure 1The weighing structure 100 is a weighing and measuring device in the prior art, such as a weighing counter, a weighing and measuring machine, etc. Since the weighing principle of the weighing structure 100 is a prior art, it will not be described in detail in this embodiment. The second support plate 202 and the first support plate 201 are supported by rods of different diameters, so that the second support plate 202 can be removed from the first support plate 201. The support legs 203 are hinged to the first support plate 201, so that the support legs 203 can play a supporting role for the first support plate 201. When not used for weighing, the support legs 203 are in contact with the ground and are perpendicular to the first support plate 201. The bottom end of the movable leg 204 and the two sides of the load-bearing plate 205 are both arc-shaped, so that when the movable leg 204 rotates toward the load-bearing plate 205, the setting of the arc state of the two parts being squeezed can be used to make the movable leg 204 rotate to the top of the load-bearing plate 205, and at the same time, the movable leg 204 generates a squeezing force on the load-bearing plate 205 , because the load-bearing plate 205 cannot move downward under the support of the weighing structure 100, the force generated by the squeezing of the movable legs 204 and the load-bearing plate 205 will act on the first support plate 201, so that the first support plate 201 generates an upward force, driving the first support plate 201 to move upward, so that the support legs 203 lose the force of supporting the ground, causing the overall support point to act on the bottom of the movable legs 204, thereby, the weighing structure 100 can be used to support the first support plate 201 and The bed supported by the second support plate 202 is weighed, and a shift rod 206 is movably interspersed between the load-bearing plate 205 and the weighing structure 100. The shift rod 206 is arranged in a concave shape, and the bottom end of the shift rod 206 is fixed to the top of the weighing structure 100, and the top end of the shift rod 206 is movably interspersed with the top of the load-bearing plate 205. The length of the exposed load-bearing plate 205 can limit the movable leg 204 in the inclined state after the movable leg 204 rotates to the top of the load-bearing plate 205.

[0044] Among them, a driving mechanism 300 for rotating the movable leg 204 is arranged between the movable leg 204 and the second support plate 202, and the driving mechanism 300 includes a hinged rod 301 and a pull rope 302. The hinged rod 301 is hinged between the second support plate 202 and the movable leg 204, and the middle part of the hinged rod 301 is hinged. The pull rope 302 is fixed to the middle part of the hinged rod 301, and a winding wheel 304 is fixedly arranged at the end of the pull rope 302 away from the hinged rod 301. A motor 305 is arranged at one end of the winding wheel 304 for transmission. The winding wheel 304 is driven by the motor 305 to reel in and unwind the pull rope 302, wherein a guide roller 303 is arranged between the pull rope 302 and the first support plate 201, and the guide roller 303 is used to adjust the force direction of the pull rope 302.

[0045] Specific reference Figure 1The hinged rod 301 is composed of two rod bodies, the opposite ends of the two rod bodies are hinged to each other, and the ends of the two rod bodies that are separated from each other are hinged to the second support plate 202 and the movable leg 204 respectively. One end of the pull rope 302 is fixed to the middle part of the hinged rod 301, and the other end of the pull rope 302 is fixed to the winding wheel 304, and the pull rope 302 can be wound around the outer wall of the winding wheel 304 through the rotation of the winding wheel 304. The guide roller 303 is movably installed at the bottom end of the first support plate 201 to adjust the force direction of the pull rope 302. The winding wheel 304 is movably installed at the top end of the first support plate 201, and the motor 305 is fixedly installed at the top end of the first support plate 201. The motor 305 is electrically connected to the external power supply through an external control switch.

[0046] Embodiment 1: When weighing, the motor 305 is started to drive the winding wheel 304 to rotate. The winding wheel 304 rotates and the pull rope 302 is wound up, so that one end of the pull rope 302 generates a pulling force on the hinged rod 301, so that the middle part of the hinged rod 301 moves toward the middle part of the first support plate 201, and the movable leg 204 is driven to rotate while moving. After the bottom end of the rotating movable leg 204 reaches the side of the load-bearing plate 205, it will squeeze the load-bearing plate 205, so that the first support plate 201 is forced to move up on the basis that the load-bearing plate 205 cannot move downward, until the bottom end of the movable leg 204 squeezes the gear lever 206, and the drive of the motor 305 is stopped. At this time, the second support plate 202 has lifted the bed, thereby completing the weighing of the bed and the patient.

[0047] Embodiment 2, as Figure 7 As shown in, after weighing is completed, when the movable leg 204 is folded and stored, the detachable structure between the two winding wheels 304 is utilized to release the synchronous rotation between the two movable legs 204, and a retractable rod body is movably interlaced between the two winding wheels 304, and the cross-section of the retractable rod body is rectangular, which is convenient for the connection and use between the two winding wheels 304, and the retractable rod body utilizes the interlacing between the protrusion and the through groove, and the protrusion is any one of elastic plastic or other elastic metal structures, which can be separated from the through groove under the pressure of external force, so that the retractable rod body can be contracted, and then can be removed from between the two winding wheels 304, so that the two movable legs 204 can be rotated and folded toward the bottom end of the first support plate 201 successively under the action of external force, thereby reducing the space occupied by the storage of the load-bearing mechanism 200 and improving the convenience of carrying and moving the load-bearing mechanism 200.

[0048] A supporting mechanism 400 is arranged between the first supporting plate 201 and the load-bearing plate 205, and the supporting mechanism 400 includes a first supporting rod 401 and a first sleeve 403.

The first sleeve 403 is a hollow structure, and the top view cross-section of the second support rod 404 is rectangular. Correspondingly, the top of the movable rod 402 is opened The groove is also rectangular, and the third support rod 411 is fixedly arranged on the bottom end of the first support plate 201. The first sleeve 403, the groove at the top of the movable rod 402 and the groove at the top of the first support rod 401 are arranged so that after the second support rod 404 can be stored in the inner cavity of the movable rod 402, the movable rod 402 is moved toward the inner cavity of the first support rod 401 for storage, and the first sleeve 403 is sleeved on the outer wall of the first support rod 401. Then the first support rod 401 is rotated to remove the first support rod 401 from the top of the load-bearing plate 205, and finally the first support rod 401 is placed horizontally between the two gear rods 206, so that the gear rod 206 can be used to maintain the shape of the first support rod 401 and the movable rod 402 after storage, thereby reducing the space occupied by the first support rod 401, the movable rod 402 and other structures when not in use, which facilitates the storage and carrying of the support mechanism 400.

[0050] The support mechanism 400 also includes a first fixed rod 405 and a second fixed rod 406. The first fixed rod 405 is fixedly arranged at the top end of the second support rod 404, and the second fixed rod 406 is sleeved on the top end of the first fixed rod 405. A meshing assembly for rotating the second fixed rod 406 is arranged above the second fixed rod 406. The meshing assembly includes a gear 407, a tooth plate 408 and a push plate 409. The gear 407 is fixedly arranged at the top end of the second fixed rod 406, and the tooth plate 408 is meshed with one side of the gear 407. A first spring 410 is fixedly arranged on one side of the tooth plate 408. The push plate 409 is fixedly arranged on the outer wall of the pull rope 302, and the push plate 409 is squeezed toward the tooth plate 408 as the pull rope 302 is wound.

[0051] Specific reference Figure 2 and Figure 3 The first fixing rod 405 and the second fixing rod 406 are cylindrical. The first fixing rod 405 is fixedly arranged with the top end of the second support rod 404. The second fixing rod 406 is fixedly arranged with the gear 407, and rotates with the rotation of the gear 407. The tooth plate 408 is movably installed inside the first support plate 201 through the first spring 410, and the push plate 409 is fixedly sleeved on the outer wall of one of the pull ropes 302. As the pull rope 302 is wound and unwound, the first fixing rod 405 and the bottom end of the second fixing rod 406 are inserted and connected, and the connection relationship between the two is limited by the limiting mechanism 500, so that when it is needed, When the first fixed rod 405 and the second fixed rod 406 are to be separated, after the load-bearing plate 205 is removed from the weighing structure 100, the motor 305 can be continuously driven so that the pull rope 302 drives the push plate 409 to move toward the tooth plate 408 until the tooth plate 408 is squeezed, causing the tooth plate 408 to move laterally, thereby driving the gear 407 to rotate, and after the rotation, driving the limiting mechanism 500 to release the limiting of the first fixed rod 405 and the second fixed rod 406. Conversely, after the push plate 409 releases the squeezing of the tooth plate 408, the tooth plate 408 can use the elastic support of the first spring 410 to reset its position.

[0052] A limiting mechanism 500 is arranged between the first fixed rod 405 and the second fixed rod 406, and the limiting mechanism 500 includes a limiting rod 501 and a limiting groove 502. The limiting rod 501 is movably arranged on the outer wall of the second fixed rod 406, and the outer wall of the limiting rod 501 is sleeved with a second sleeve 503 for limiting the position of the limiting rod 501. The limiting groove 502 is opened on the outer wall of the first fixed rod 405, and the limiting groove 502 is used for limiting the connection between the first fixed rod 405 and the second fixed rod 406 by interlacing connection with the limiting rod 501. The limiting mechanism 500 also includes a second spring 504 and a rotation groove 505. The second spring 504 is fixedly arranged between the limiting rod 501 and the second sleeve 503. The rotation groove 505 is opened at the top end of the third support rod 411, and the rotation groove 505 is used to provide rotation space for the limiting rod 501 and limit the position of the limiting rod 501.

[0053] Specific reference Figure 4 and Figure 5 The limiting rod 501 is installed on the outer wall of the second fixing rod 406 by means of the second sleeve 503, and the limiting rod 501 can penetrate into the inner cavity of the second fixing rod 406 and be connected with the outer wall of the first fixing rod 405 by means of the elastic support of the second spring 504, so that the second spring 504 can be fixedly sleeved on the outer wall of the limiting rod 501, and the rotation groove 505 is opened, so that the space range of the limiting rod 501 rotation is different. When the first fixing rod 405 and the second fixing rod 406 are inserted, the limiting rod 501 is in the inner cavity of the rotation groove 505 with a large space range, so that the first fixing rod 405 exerts a certain pressure on the limiting rod 501. During extrusion, the limit rod 501 can move toward the inner wall of the rotating groove 505 after being compressed. When the first fixed rod 405 and the second fixed rod 406 are inserted and connected, the limit rod 501 will be at the same horizontal position as the limit groove 502. Then the second fixed rod 406 rotates, driving the limit rod 501 to rotate synchronously. After rotation, the limit rod 501 is squeezed by the inner wall of the rotating groove 505 and moves toward the inner cavity of the limit groove 502, so that it can be embedded in the limit groove 502, and then the first fixed rod 405 and the second fixed rod 406 can be connected with each other under the cooperation of the meshing of the gear 407 and the tooth plate 408. The stability of the connection between the first fixed rod 405 and the second fixed rod 406 is maintained.

[0057] Step 1: Install the support mechanism 400 under the first support plate 201, take out the first support rod 401 from between the two gear rods 206, and after taking it out, connect the first support rod 401 with the top of the load-bearing plate 205, then rotate the first support rod 401 so that the first support rod 401 is limited in position by the shape difference with the inner cavity of the groove at the top of the load-bearing plate 205, move the second support rod 404 and the second fixing rod 406 upward to connect with the third support rod 411, during this process, the tooth plate 408 is squeezed by the push plate 409 to control the limit rod 501 and the limit groove 502 to be in a separated state, after the insertion is completed, drive the motor 305 to control The reel 304 unwinds the pull rope 302, causing the push plate 409 to lose its squeezing force on the tooth plate 408, so that the tooth plate 408 moves laterally under the elastic support of the first spring 410, and drives the gear 407 to rotate, and drives the limit rod 501 to move while rotating, until it stops moving after being interlaced and connected with the limit groove 502. In the above, through the assembly of the support mechanism 400 and the load-bearing mechanism 200, the weighing structure 100 is indirectly related to the load-bearing mechanism 200, and finally the load-bearing mechanism 200 is installed under the bed, so that the third support plate 207 contacts the bottom end of the bed, so that the support leg 203 is squeezed with the ground to maintain the overall stability;

[0058] When weighing, by starting the motor 305, the motor 305 drives the reel 304 to reel the pull rope 302, so that the middle part of the hinged rod 301 moves toward the pull rope 302. During the movement, a pulling force is generated on the movable leg 204, so that the movable leg 204 rotates with the top as the rotation point. During the rotation, the bottom end of the movable leg 204 squeezes the load-bearing plate 205, so that the load-bearing plate 205 generates a downward force by the elastic support between the first support rod 401 and the movable rod 402, and cooperates with the squeezing of the weighing structure 100 below the load-bearing plate 205 and the ground, so that the movable rod 402 drives the first support plate 201 to move upward, and then the third support plate 207 can generate a lifting force on the bed, so that the center of gravity of the bed is on the movable leg 204, thereby using the weighing of the weighing structure 100 to complete the weighing of the patient;

[0059] Step 2: After assembling the supporting mechanism 400 and the first supporting plate 201, the third supporting plate 207 can be removed separately and placed on the bed and under the patient. The distance between the third supporting plate 207 and the second supporting plate 202 can be adjusted by rotating the bolts, so that there is a certain distance between the second supporting plate 202 and the bottom of the bed. When weighing, the first supporting plate 201 is lifted by the rotation of the movable legs 204. When the second supporting plate 202 drives the third supporting plate 207 to rise in position, only the patient will be lifted, and weighing can be performed without lifting the bed.
