Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is an external view of an ultrasonic apparatus, in which fig. 1a is a perspective view of the portable ultrasonic apparatus, fig. 1b is a state of the ultrasonic apparatus after a display LCD is opened, and fig. 1c is a bottom view of the ultrasonic apparatus.
In fig. 1, 4 fixing members 1-a for fixing the ultrasonic device to the cart are provided at the bottom of the ultrasonic device. The fixing member 1-a is provided in the present invention, for example, in a structure having a large hole and a small hole (see an enlarged partial view in fig. 1 c), and is fitted to the shape of the small hooks 3-b, 3-c (fig. 3) of the locking mechanism of the cart, and the small hooks 3-b, 3-c are inserted into the hooking small holes (see fig. 4) from the large hole in accordance with the rotation of the handle 3-a, thereby fixing the ultrasonic device.
Fig. 2 is an external view of a cart for placing a fixed ultrasonic device. The cart has a mounting table on which the ultrasonic device is mounted. For positioning the carriage and the ultrasonic apparatus, for example, 4 stand legs may be provided on the ultrasonic apparatus, and a guide portion and a fitting portion may be provided on a mounting table of the carriage. When the ultrasonic device is placed, the table legs slide forwards along the guide part, and after reaching the embedding part, the table legs are embedded with the embedding part, so that the ultrasonic device is positioned at a preset position. In FIG. 2, 2-a is a window hole provided for the entrance and exit of the hooks 3-b, 3-c.
Fig. 3 is a schematic view of a locking mechanism of the dolly.
In fig. 3, the locking mechanism is provided with a handle 3-a, the handle 3-a is provided with a long hole 3-f, a guide shaft 3-e is arranged in the long hole 3-f, and the guide shaft 3-e is fixed on a rotating shaft 3-d. The handle 3-a is prevented from rotating with respect to the rotating shaft 3-d by the guide shaft 3-e, and is restricted in the moving distance in the axial direction by the elongated hole 3-f. Two small hooks 3-b are arranged on the rotating shaft 3-d, the rotating shaft 3-d is fixed on the same angle, and the connecting shaft 3-g is respectively linked with the two small hooks 3-c for fixing. Therefore, after the ultrasonic device is loaded to a preset position of the special trolley, the handle 3-a is rotated clockwise, the 4 small fixing hooks 3-b and 3-c and the fixing component 1-a at the position 4 of the ultrasonic device are buckled together, and the ultrasonic device is fixed on the special trolley.
In fig. 3, the lock mechanism further has a cam body 4-a and a pressing piece 5-a provided at a position perpendicular to the rotational axis 3-d of the cam body 4-a and pressed against the cam body 4-a by the elastic force of a spring 5-b, and the structure of the cam body 4-a and the pressing piece 5-a will be described later.
Fig. 4 is a schematic view of the locking and unlocking process of the locking mechanism.
With the rotation of the handle 3-a, the small hooks 3-b, 3-c are inserted into the small holes from the large holes of the fixing member 1-a and hooked on the small holes, thereby fixing the ultrasonic device.
Fig. 5a and 5b are schematic views of the structure of the handle and cam of the locking mechanism. Wherein fig. 5b is a schematic view of the cam of fig. 5a rotated to a different angle. On the handle 3-a, a cam is provided, which includes an outer cam 4w and a cam body. The outer cam 4w is an arc body having a radius larger than the rotation shaft 3-d. The cam body is composed of a locking cam 4-b, a releasing cam 4-c and a baffle 4-d. In the cam, the start surface of the locking cam 4-b and the end surface of the releasing cam 4-c are the same surface 4-e, and the start surface of the releasing cam 4-c and the end surface of the locking cam 4-b are the same surface 4-f. The 4-e surface and the 4-f surface respectively form an upper slot and a lower slot with the radial surface of the outer cam 4w opposite to the upper slot and the lower slot. The locking cam 4-b and the releasing cam 4-c are separated by a shutter 4-d at a portion other than the same surface. The guide shaft 3-e moves in the elongated hole 3-f, and the handle 3-a is restricted by the guide shaft 3-e from moving between predetermined positions by the action of the spring 3-h.
Fig. 6a-6c are schematic views of the cam profile when the locking mechanism of the present invention is locked.
If the operator rotates the handle clockwise, the pressing piece 5-a, which is disposed at a position perpendicular to the rotational axis of the cam and abuts against the cam with the spring 5-b, slides along the curved surface of the locking cam 4-b (see fig. 3). After reaching the end surface 4-f of the locking cam 4-b, as shown in fig. 6c, the pressing piece 5-a is stuck in the lower slot, and the handle can not rotate any more, so that the rotation of the small hooks 3-b, 3-c is fixed, and finally the ultrasonic device is locked.
Fig. 7a-7c are schematic views of the cam profile when the locking mechanism of the present invention is unlocked.
If the operator wants to unlock, the handle 3-a is pushed forward (left side of fig. 5) in the locked state, and the guide shaft 3-e is positioned at the right end of the elongated hole 3-f. The presser plate 5-a is thus moved from the end face of the position of the locking cam 4-b to the start face of the releasing cam 4-c, which are located on the same face 4-f as previously described. At this time, if the handle 3-a is rotated counterclockwise, the pressing piece 5-a slides along the curved surface of the release cam 4-c, and the pressing piece 5-a reaches the end surface 4-e of the release cam 4-c, the rotation is stopped (fig. 7c), and the operator can feel that the release is performed. When the operator removes the hand from the handle, the spring 3-g springs the handle 3-a back, and the hooks 3-b, 3-c are disengaged from the fixing member 1-a at the bottom of the ultrasonic device, so that the pressing piece returns to the position of the start surface of the locking cam 4-b.
The cam referred to herein generally means a shape having an arc section, and in the present invention, as a preferred embodiment, the radial radius of the locking cam 4-b is gradually increased from the start surface to the end surface; the radial radius of the release cam 4-c gradually increases from the start surface to the end surface. However, since the start surface of the locking cam 4-b and the end surface of the releasing cam 4-c are the same surface 4-e, and the start surface of the releasing cam 4-c and the end surface of the locking cam 4-b are the same surface 4-f, the radial radii of the locking cam 4-b and the releasing cam 4-c increase in opposite directions. Therefore, the force of the operating handle is gradually increased when the pressing piece 5-a slides along the curved surface of the locking cam 4-b during the locking process, and the force of the operating handle is gradually increased when the pressing piece 5-a slides along the curved surface of the releasing cam 4-b during the unlocking process, thereby improving the operability and reducing the possibility of misoperation.
In addition, since the locking cam 4-b and the releasing cam 4-c are separated by the shutter 4-d at the other portions except the start surface and the end surface, the pressing piece 5-a is prevented from moving between the locking cam 4-b and the releasing cam 4-c when the handle 3-a is rotated, thereby preventing an erroneous operation.
In this embodiment, the lock can be performed by rotating the handle 3-a, and the lock can be released by pushing the handle 3-a forward with force and rotating it in the reverse direction when unlocking, so that the problem of the lock release due to an inadvertent operation by the operator can be reliably prevented. Thereby effectively avoiding the damage to the human body and the ultrasonic device.
Modification example
In the above embodiment, the cam is provided on the handle, and the position of the cam is changed by moving the handle in the direction of the rotational axis.
Fig. 8 shows a structure of a modification.
A cam 6-b movable in the direction of the rotation axis is provided on the rotation shaft 6-a, and the movable range is limited by a long hole and a guide shaft 6-e moving in the long hole. The cam 6-b is movably fitted to the handle 6-f, and the handle is fixed by penetrating the rotation shaft 6-a with the guide shaft 6-e. The cam uses a spring 3-h to keep the start surface of the locking cam 6-b in line with the position of the pressing piece 5-a. The edge 6-g of the cam 6-b now protrudes beyond the handle 6-f.
When the operator rotates the handle 6-f clockwise, the pressing piece 5-a attached to the cam by the action of the spring 5-b perpendicularly to the rotational axis of the cam slides along the curved surface of the cam. Upon reaching the end of the fixed cam 6-b, the handle cannot be rotated any further, while the pressing piece 5-a is embedded in the cam 6-b in order to prevent the handle 6-f from rotating in the counterclockwise direction.
When released, the projection 6-g of the cam 6-b is pressed into a position defined by the guide shaft 6-e in the locked state. By pressing the cam 6-b in, the cam 6-b moves relative to the pressing piece 5-a from the end face of the position of the locking cam 4-b to the start face of the releasing cam 6-d. In this state, the handle 6-d is rotated counterclockwise, and the fixing can be released. The pressing piece 5-a cannot move any more after reaching the end surface of the release cam, and then the cam 6-b is bounced back due to the force of the spring 3-h, so that the pressing piece reaches the position of the start surface of the locking cam 6-c.
The locking mechanism of the trolley can be reliably fixed only by rotating the handle when locking, and when releasing, the handle can not be rotated towards the releasing direction if the operation of pushing the handle and rotating the cam is not carried out, and the cam can not move due to the existence of the arranged baffle plate during the operation process of rotating the handle, thereby preventing the trouble caused by misoperation and careless operation and ensuring the safety.
