When the workstation 30 is used, the workstation 30 and the support seat 11 are quickly and stably installed through the connecting assembly 20 and the support assembly, so that the risk to an operator due to instable installation or installation error of the workstation 30 is avoided; when the workstation 30 is not used, the clamping pin 22 is withdrawn from the clamping groove 112, and the workstation 30 is further withdrawn from the supporting seat 11, so that the volume of the medical imaging device can be reduced.

It can be understood that the specific shapes of the limiting hole 111 and the locking groove 112 are not limited in this embodiment, for example, the limiting hole 111 may be a circular hole, a polygonal hole, an elliptical hole, or an irregular hole, and in addition, the limiting hole 111 may be a through hole or a blind hole; the detent groove 112 may be a circular groove, a rectangular groove, or the like. In addition, the limiting pin 21 can move in the limiting hole 111, the radial dimension of the limiting hole 111 is larger than that of the limiting pin 21, the radial dimension refers to the maximum radial dimension of the limiting hole 111, and when the limiting hole 111 is a circular hole, the diameter is the diameter; the radial dimension of the limit pin 21 is the same.

Preferably, the cross section of the limiting hole 111 along the axial direction is substantially trapezoidal, and the limiting hole 111 is bowl-shaped or trumpet-shaped as a whole, so that the limiting pin 21 is convenient to deflect after being inserted. Specifically, the radial dimension (i.e., the aperture or the opening degree) of the stopper hole 111 gradually increases in a direction approaching the detent groove 112, and the aperture of the stopper hole 111 gradually increases in a direction from left to right, taking fig. 2 as an example.

Specifically, the axial directions of at least two limiting holes 111 may be parallel to each other, and both may be parallel to the plane where the surface of the supporting seat 11 is located; the axial directions of at least two limiting holes 111 may be parallel to each other, and the axial direction of at least one limiting hole 111 and the supporting seat 11 are arranged at an angle, that is, at least one limiting hole 111 is arranged obliquely relative to the supporting seat 11; the axial directions of the at least two limiting holes 111 may be parallel to the plane of the surface of the supporting base 11, and the axial directions of the at least two limiting holes 111 are mutually inclined. For example, in fig. 2, two limiting holes 111 are located at two adjacent corners of the supporting seat 11, and the axial directions of the two limiting holes 111 are parallel to each other, although the axial directions of the two limiting holes 111 in fig. 1 may also be inclined toward each other.

In other embodiments, the axial direction of the at least one position-limiting hole 111 may be perpendicular to the supporting base 11, that is, the position-limiting hole 111 extends along the vertical direction of the supporting base 11, and at this time, the position-limiting pin 21 may be arranged in a bent shape or a curved shape; or the limiting hole 111 has an opening (or notch) along the radial direction, and the opening is communicated with one end of the limiting hole 111 for the extending-in of the limiting pin 21, so that the limiting pin 21 can be accommodated in the opening after deflection. For example, the position-limiting hole 111 is perpendicular to the supporting base 11, the position-limiting pin 21 is V-shaped (the opening of the V is larger) or L-shaped, one section of the V or L is inserted into the position-limiting hole 111, and the other section is located outside the position-limiting hole 111.

With this arrangement, it is possible to prevent the locking pin 12 from being withdrawn from the latching groove 112 due to an insufficient length of the locking pin 12 within the latching groove 112.

Further, the position limiting assembly 10 further includes an elastic element 13, one end of the elastic element 13 is fixed on the support base 11, and the other end of the elastic element is connected to the locking pin 12, for applying an elastic force along the radial direction of the locking groove 112 to the locking pin 12, so that a part of the locking pin 12 is located within the range of the locking groove 112. In an exemplary embodiment, the elastic member 13 is a spring, and one end of the spring is connected to the supporting seat 11 through a top thread 15.

Furthermore, the end of the locking pin 12 close to the locking groove 112 is wedge-shaped, the inclined plane of the wedge-shape deviates from the locking groove 112, and the inclined plane of the wedge-shape is used for abutting against the locking pin 22. Actually, workstation 30 drives the deflection of gag pin 21 along spacing hole 111 under the effect of gravity, and through the one end that disposes lock round pin 12 is the wedge, workstation 30 drives screens round pin 22 under the effect of gravity and continues to move down to screens round pin 22 and wedge-shaped inclined plane and lean on, exerts pressure to the inclined plane afterwards, makes lock round pin 12 withdraw from the scope of screens groove 112 gradually, thereby makes lock round pin 12 get into screens groove 112, and thereafter wedge-shaped inclined plane is owing to not having the pressure that screens round pin 22 exerted, and lock round pin 12 resets to at least partly in the scope of screens groove 112. It should be noted that the wedge-shaped inclined plane described herein includes, but is not limited to, an inclined plane as a whole, and may also be formed by connecting a plurality of small planes in sequence, and the angle between two adjacent small planes may be, for example, ± 15 °.

Optionally, the limiting assembly 10 further includes an unlocking block 14, and the unlocking block 14 is fixedly connected to the locking pin 12 and configured to move along the supporting seat 11 to drive the locking pin 12 to move. Further, the unlocking block 14 comprises a pressing part, so that an operator can push the unlocking block 14 to move after pressing the pressing part, and then the locking pin 12 is driven to move. As for the specific structure of the pressing portion, it can be formed by a part of the unlocking block 14 protruding outward, for example, a part of the unlocking block 14 is formed by protruding along a vertical direction of the supporting seat 11 (shown in fig. 4), and it can be a part of the unlocking block 14 protruding along a direction parallel to the supporting seat 11, or a part of the unlocking block 14 protruding along a direction inclined to the supporting seat 11.
