Description

Technical Field

[0001] This utility model belongs to the field of human skeleton models, and specifically relates to a human skeleton model placement rack. Background Technology

[0002] Human skeletal models are an important tool in medical education, helping students better understand the structure of the human skeleton, principles of movement, and treatment of bone injuries. Through these models, students can visually observe the shape of the bones, their connections, and the functions of different parts, thereby deepening their understanding and retention of medical knowledge.

[0003] In medical teaching demonstrations, a support frame is needed to hold the human skeleton model. Existing human skeleton models are supported by hanging rings on the top of the model's head and hooks on the top of the support frame. While this is convenient for the placement and installation of the human skeleton model, the model has too much freedom during the transfer process and is prone to swaying uncontrollably. This can cause the hooks to detach from the hanging rings, resulting in the human skeleton model falling and being damaged. Therefore, a human skeleton model support frame is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a human skeleton model placement rack, which solves the problems in the existing technology.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A human skeleton model placement rack includes a base with at least three casters at the lower end of the base, a support column fixed at the upper end of the base, a lifting rod that can be raised and lowered on the support column, a hook fixed on the lifting rod, a hanging ring attached to the hook, and the hanging ring fixed to the top of the human skeleton model.

[0007] A fixing block is provided on one side of the support column, and a flip-up connecting block is provided on the fixing block. An installation plate is fixed on the connecting block, and two connecting plates that can slide synchronously in opposite directions are provided on the installation plate. A clamp is fixed on each of the two connecting plates. The two clamps are close to each other to clamp the human skeleton model, preventing the skeleton model from shaking and falling during transportation, which would cause damage. In addition, during the teaching demonstration, the connecting block can be controlled to flip downwards to prevent the clamps from interfering with the teaching demonstration of the human skeleton model.

[0008] Furthermore, the lifting rod and the support column are slidably connected in the vertical direction. Two first fixing plates are provided on one side of the support column, and a first screw rod that can rotate is provided between the two first fixing plates. A second fixing plate is provided on one side of the lifting rod, and the first screw rod passes through the second fixing plate in the vertical direction and is threadedly connected to it.

[0009] Furthermore, the thread helix angle of the first lead screw is less than the equivalent friction angle.

[0010] Furthermore, the connecting block is provided with a rotating shaft, which is rotatably connected to the fixed block, and a motor is provided on the fixed block to drive the rotating shaft to rotate.

[0011] Furthermore, both connecting plates are slidably connected to the mounting plate, and two third fixing plates are fixed on the mounting plate. A rotatable second lead screw is provided between the two third fixing plates. The second lead screw is provided with a first external thread and a second external thread with opposite directions and equal pitch. The first external thread and the second external thread pass through the two connecting plates and are threadedly connected to them.

[0012] Furthermore, the thread helix angle of both the first and second external threads is less than the equivalent friction angle.

[0013] Furthermore, both of the clamps are arc-shaped.

[0014] Furthermore, the fixing block can be adjusted by sliding in the vertical direction.

[0015] Furthermore, the fixing block and the support column are slidably connected in the vertical direction. Two fourth fixing plates are provided on the upper part of the support column, and a rotatable third lead screw is provided between the two fourth fixing plates. The third lead screw passes through the fixing block in the vertical direction and is threadedly connected to it.

[0016] Furthermore, the thread helix angle of the third lead screw is less than the equivalent friction angle.

[0017] The beneficial effects of this utility model are:

[0018] 1. By installing a lifting rod that can be raised and lowered on the support column, and attaching hooks to the lifting rings at the top of the skeleton model, human skeleton models of different heights can be lifted for teaching demonstrations. Furthermore, by installing a clamping assembly on one side of the support column, with a flip-up connecting block on the clamping assembly, the flipping adjustment of the clamping plate can be controlled. This ensures that the clamping plate firmly holds the human skeleton model during transport, preventing it from shaking and falling, thus avoiding damage. Additionally, during teaching demonstrations, the connecting block can be flipped downwards to prevent the clamping plate from interfering with the teaching demonstration of the human skeleton model.

[0019] 2. By making the clamping components height-adjustable, it is ensured that the two clamping plates can still clamp the upper body of the human skeleton model after the height of the lifting rod is adjusted, thus ensuring clamping stability. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 As shown, a human skeleton model placement rack includes a base 1, and four casters are provided at the lower end of the base 1 to facilitate the movement of the base 1 and even the placement rack, so as to realize the transfer of the human skeleton model; and the casters are equipped with brakes to facilitate the stopping of the base 1 during teaching demonstrations.

[0029] Of course, the number of casters at the lower end of the base 1 includes, but is not limited to, the four in this embodiment. In some embodiments, the number of casters at the lower end of the base 1 can be three or four or more; as long as it can provide stable support for the base 1 and retain its displacement capability, it is acceptable.

[0030] A support column 2 is fixed to the upper end of the base 1, and a lifting rod 3 that can be raised and lowered is provided on the support column 2. Figure 3As shown, a hook 31 is fixed to the upper end of the lifting rod 3, and a hanging ring 7 is fixed to the top of the human skeleton model. The hook 31 can be hooked to the hanging ring 7, thereby enabling the human skeleton model to be lifted for teaching demonstration.

[0031] In this embodiment, the lifting rod 3 and the support column 2 are slidably connected in the vertical direction, such as... Figure 2 and Figure 3 As shown, two first fixing plates 21 are provided on one side of the support column 2, and a first lead screw 4 is rotatably connected between the two first fixing plates 21. A second fixing plate 32 is provided on one side of the lifting rod 3. The first lead screw 4 passes through the second fixing plate 32 in the vertical direction and is threadedly connected to it. By setting a motor on one of the first fixing plates 21 to drive the first lead screw 4 to rotate, the lifting height of the lifting rod 3 can be adjusted to accommodate human skeleton models of different sizes (for example, the height of male skeleton models and female skeleton models are different, so the height of the lifting rod 3 needs to be adjusted accordingly to hang the skeleton model for display).

[0032] Furthermore, in order to ensure that the height position of the lifting rod 3 remains stable after adjustment, the first lead screw 4 needs to have self-locking properties, that is, the thread helix angle of the first lead screw 4 is less than the equivalent friction angle.

[0033] Of course, the lifting rod 3 can be adjusted by means of structures such as the first lead screw 4 in this embodiment. In some embodiments, the lifting rod 3 can also be directly driven to rise and fall by linear drive components such as cylinders and telescopic rods on the support column 2.

[0034] A clamping component 5 is provided on one side of the support column 2. The clamping component 5 can clamp the upper body of the human skeleton model to prevent the skeleton model from shaking during transportation, which would cause the lifting ring 7 to detach from the hook 31 and thus cause the skeleton model to fall and be damaged.

[0035] like Figure 4 As shown, the clamping assembly 5 includes a fixing block 51 installed on one side of the support column 2. The fixing block 51 is provided with a connecting block 52 that can be flipped and adjusted. The connecting block 52 is fixed with a mounting plate 53. The mounting plate 53 is provided with two connecting plates 54 that can slide synchronously in opposite directions. Each of the two connecting plates 54 is fixed with a clamping plate 55. The two clamping plates 55 move closer to each other synchronously, which can clamp the upper body of the human skeleton model.

[0036] During teaching demonstrations, the connecting block 52 is flipped downwards to avoid interference from the clamping component 5 in displaying the human skeleton. During transport, the connecting block 52 is flipped to a horizontal position, and then the two clamping plates 55 are controlled to move closer together to clamp the skeleton and prevent it from shaking during transport.

[0037] In this embodiment, as Figure 5As shown, a rotating shaft 521 is provided on the connecting block 52. The rotating shaft 521 is rotatably connected to the fixed block 51, and a motor is provided on the fixed block 51 to drive the rotating shaft 521 to rotate, so that the connecting block 52 can be rotated and adjusted around the rotating shaft 521.

[0038] In this embodiment, both connecting plates 54 are slidably connected to the mounting plate 53. Two third fixing plates 531 are fixed on the mounting plate 53, and a second lead screw 56 is rotatably connected between the two third fixing plates 531. Figure 6 As shown, the second lead screw 56 is provided with a first external thread 561 and a second external thread 562 with opposite directions of rotation and equal pitch. The first external thread 561 and the second external thread 562 pass through the two connecting plates 54 and are threadedly connected to them. By setting a motor on one of the third fixing plates 531 to drive the second lead screw 56 to rotate, the synchronous reverse sliding of the two connecting plates 54 can be realized, that is, the synchronous reverse sliding of the two clamping plates 55 can be driven.

[0039] Furthermore, in order to ensure the stability of clamping the human skeleton model, the second lead screw 56 needs to have self-locking properties, that is, the thread helix angle of the first external thread 561 and the second external thread 562 is less than the equivalent friction angle.

[0040] In other embodiments, two connecting plates 54 can be directly driven to slide synchronously in opposite directions by setting two cylinders on the mounting plate 53.

[0041] In addition, the clamps 55 are arc-shaped, and the two clamps 55 are close to each other to hold the upper body of the human skeleton model tightly.

[0042] The fixing block 51 can slide and adjust in the vertical direction, thereby adjusting the clamping height of the two clamping plates 55 to ensure that after the height position of the lifting rod 3 is adjusted, the two clamping plates 55 can still clamp the upper body position of the human skeleton model.

[0043] In this embodiment, the fixing block 51 and the support column 2 are slidably connected in the vertical direction. Two fourth fixing plates 22 are provided on the support column 2. A third lead screw 6 is rotatably connected between the two fourth fixing plates 22. The third lead screw 6 passes through the fixing block 51 in the vertical direction and is threadedly connected to it. By setting a motor on one of the fourth fixing plates 22 to drive the third lead screw 6 to rotate, the height position of the fixing block 51 can be adjusted. Furthermore, the thread helix angle of the third lead screw 6 is less than the equivalent friction angle to ensure that the height position of the fixing block 51 remains stable after adjustment.

[0044] Of course, the methods for adjusting the height of the fixed block 51 include, but are not limited to, the third lead screw 6 and other structures in this embodiment. In some embodiments, the fixed block 51 can also be directly driven to rise and fall by setting linear drive components such as cylinders and telescopic rods on the support column 2.

[0045] Working principle:

[0046] A lifting rod 3 capable of being raised and lowered is installed on the support column 2. A hook 31 is installed on the lifting rod 3 to connect with the hanging ring 7 at the top of the skeleton model, allowing for the hoisting of human skeleton models of different heights for teaching demonstrations. A clamping assembly 5 is installed on one side of the support column 2, with a flip-out connecting block 52 on the clamping assembly 5. This controls the flipping adjustment of the clamping plate 55, ensuring that the clamping plate 55 clamps the human skeleton model tightly during transport, preventing it from shaking and falling, thus avoiding damage. Furthermore, during teaching demonstrations, the connecting block 52 can be flipped downwards to prevent the clamping plate 55 from interfering with the teaching demonstration of the human skeleton model. By making the clamping assembly 5 height-adjustable, it ensures that even after adjusting the height of the lifting rod 3, the two clamping plates 55 can still clamp the upper body of the human skeleton model, guaranteeing clamping stability.
