As shown in fig. 1 to 2, in particular to a horizontal lower limb load simulator, which comprises a seat body 1, a pressurizing platform and an electronic scale 2; the pressurizing platform is arranged on the seat body 1 and is connected with a safety belt 4 through a traction belt 3; the electronic scale 2 is connected with the pressurizing platform.

It should be noted that, the seat body 1 in this embodiment may be not only a detection bed, but also an area or a position where a patient such as a floor, a carpet, a floor, etc. can lie directly.

The pressurizing platform is fixed on the seat body 1, the electronic scale 2 is fixed on the pressurizing platform, and when the pressurizing platform is specifically used, a patient wears the safety belt 4, feet contact the electronic scale 2, and the traction belt 3 is straightened, although a doctor operates the pressurizing platform, the feet of the patient are stressed through the electronic scale 2, so that the lower limb load of the patient is realized.

In the above process, the value of the electronic scale 2 is changed continuously due to the fact that the doctor operates the pressurizing platform, the changed value reflects the load condition of the lower limbs of the patient, and when the value reaches the value required by the doctor, the operation of the pressurizing platform is stopped.

When the image scanning is performed using the present embodiment, the traction belt 3 can give the patient a pulling force at all times, so that both feet of the patient are always in contact with the electronic scale 2, thereby enabling the electronic scale 2 to better obtain the simulated load value.

For better use of the present embodiment, the pressurizing platform comprises a positioning seat 5 and a pressurizing mechanism; the positioning seat 5 is connected with the traction belt 3; the pressurizing mechanism is movably connected with the positioning seat 5; the electronic scale 2 is provided in the pressurizing mechanism.

In this embodiment, the positioning seat 5 is connected to the seat body 1, and the connection may be a detachable connection. For convenience of explanation, let the seat body 1 in this embodiment be a detection bed, which has a head end and a tail end.

The positioning seat 5 is generally installed at the tail end of the detection bed, and the pressurizing mechanism is assembled to the positioning seat 5 after the positioning seat 5 is determined.

It should be noted that, when the patient lies on the detection bed, the plane of the electronic scale 2 should be as flush as possible with the foot surfaces of the feet of the patient, so as to avoid the occurrence of loading errors.

In this embodiment, the pressurizing mechanism may be configured to implement pressurizing load by using a mechanism based on pneumatic or hydraulic principle, or may be implemented by using a motor in combination with a purely mechanical mechanism, such as a remote rod mechanism, a rack and pinion mechanism, etc.

Specifically, in this embodiment, the pressurizing mechanism includes a first mounting seat 6, a hand wheel 7, and a threaded rod 8; the threaded rod 8 is in threaded connection with the positioning seat 5, one end of the threaded rod 8 is in rotary connection with the first mounting seat 6, and the other end of the threaded rod 8 is fixedly connected with the hand wheel 7; the electronic scale 2 is arranged on the first mounting seat 6.

The plane of the first mounting seat 6 is parallel to the plane of the electronic scale 2. When the hand wheel 7 rotates, the threaded rod 8 carries the first mounting seat 6 to move relative to the positioning seat 5. When the first mounting seat 6 moves towards the direction approaching the positioning seat 5, the traction belt 3 is tightened, and the load is reduced; when the first mounting seat 6 moves in a direction away from the positioning seat 5, the traction belt 3 is loosened and the load becomes large.

For better use of the present embodiment, the pressing mechanism further comprises a second mounting seat 9, and at least one guide bar 10; the guide rod 10 extends along the axial direction of the threaded rod 8, and the guide rod 10 is in sliding connection with the positioning seat 5; one end of the guide rod 10 is connected with the first mounting seat 6, and the other end is connected with the second mounting seat 9; the threaded rod 8 is in threaded connection with the second mounting seat 9.

In order to balance the movement stress of the first mounting seat 6, two guide rods 10 are symmetrically arranged relative to the threaded rod 8 on a plane taking the detection bed as a projection surface.

Therefore, when the hand wheel 7 is rotated, the first mounting seat 6 carries the electronic scale 2 to stably move along the axial extending direction of the guide rod 10, and in the moving process, the relative rotation of the electronic scale 2 and the soles of the feet of a patient can be avoided, so that the data precision is ensured.

For better use of the present embodiment, a stabilizer bar 11 is further included, the stabilizer bar 11 extending in the axial direction of the threaded rod 8, one end of the stabilizer bar 11 being connected to the electronic scale 2.

In a specific operation, the physician can rotate the hand wheel 7 with one hand and hold the stabilizer bar 11 with the other hand, so as to further improve the operation stability.

That is, the straight line of the threaded rod 8, the straight line of the guide rod 10, and the straight line of the stabilizer rod 11 are parallel to each other. Therefore, the whole structure is neat, and the operation is convenient.

For better use of the present embodiment, both ends of the positioning seat 5 are provided with traction belts 3 for connecting the safety belt 4.

Specifically, the safety belt 4 is a three-point safety belt 4; the seat belt 4 comprises a belt which is connected with the traction belt 3.
