[Problems to be solved by the invention]
The cable hanger mounting device of the above-mentioned conventional ultrasonic diagnostic device uses a ball plunger and a screw, so that the number of parts required for mounting is large, and the work at the time of mounting becomes complicated. there were. Further, since the mounting operation needs to be performed from the inside of the apparatus main body, a certain amount of space is required for the mounting portion of the apparatus, and there has been a problem that the apparatus is enlarged. An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a cable hanger mounting device capable of easily mounting a cable hanger to a main body and preventing the cable hanger from coming off.
[0004]
[Means for Solving the Problems]
The present invention relates to a cable hanger mounting device for mounting a cable hanger on a device having a cable, wherein the cable hanger, a bush into which the tip of the cable hanger is inserted, and a mounting hole on the main body side of the device into which the bush is inserted. The tip of the bush, the shape of the bush is wider than the shape of the mounting hole by inserting the cable hanger in a state where the bush is inserted into the mounting hole, and the tip of the cable hanger Engaging, thereby preventing the cable hanger and the bush from falling out of the mounting hole.
[0005]
The tip of the bush has a slit substantially parallel to the center axis of the bush, and a protrusion formed at the bottom of the through hole of the bush, and the tip of the cable hanger includes a groove, a guide, Taper, whereby when the cable hanger is inserted into the bush, the guide taper of the cable hanger pushes and spreads the convex portion of the bush, and the convex portion fits into the groove of the cable hanger. You may.
[0006]
Therefore, according to the present invention, since no ball plunger, screw or the like is used, the number of parts required for mounting is small, and the work at the time of mounting is simple. Further, since there is no need to perform the mounting operation from the inside of the apparatus main body, there is an advantage that no space is required for the mounting portion of the apparatus and the apparatus can be downsized.
[0007]
Further, the central axis of the mounting hole may be inclined toward a fixed position of the cable hanger, so that the cable hanger is always arranged at a fixed position by using its own weight. With this configuration, the cable hanger can always be arranged at a position where it will not obstruct when not in use. Therefore, it is possible to prevent the cable hanger from rotating freely and coming into contact with a wall or the like due to vibration during movement of the product.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
[0009]
FIG. 1 is a perspective view showing a component configuration of a cable hanger according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view showing a cable hanger mounting device. In FIG. 1, a cable hanger 21 is attached via a bush 22 to a mounting hole 23a formed in a main body 23 of the ultrasonic diagnostic apparatus. The bush 22 is made of an abrasion-resistant and slippery material such as a Duracon, and has a flange 22a formed on an upper portion. When the bush 22 is inserted into the mounting hole 23a, the flange 22a is connected to the mounting hole 23a. Stop at the top. Since the insertion length 1 of the bush 22 is longer than the length L of the mounting hole 23a, the tip of the bush 22 protrudes from the mounting hole 23a. In this state, a cable hanger 21 made of a hard rod-like metal such as stainless steel is inserted into the through hole 22a of the bush 22 from above. A guide taper 21a formed at the tip of the cable hanger 21 presses the convex portion 22c of the bush 22. Since the slit 22 d is provided at the tip of the bush 22, the tip of the bush is expanded by the tip of the cable hanger 21. When the cable hanger 21 is further pushed into the bush 22, the upper flange 21 c of the cable hanger 21 hits the upper portion of the bush 22 and stops. In this state, the projection 22c of the bush 22 fits into the groove 21b of the cable hanger 21. Since the diameter 21d of the groove is larger than the diameter 22e of the projection, the outer diameter 22f of the tip of the bush 22 at the time of mounting is larger than the diameter 23b of the mounting hole 23a, and the bush 22 is hard to come out of the mounting hole 23. Since the bush 22 is made of a slippery material having good wear resistance, the cable hanger 21 rotates around the rod-shaped shaft by sliding with the bush 22.
[0010]
In such a structure, since a ball plunger, a screw, and the like are not used, the number of parts required for mounting is small, and the work at the time of mounting is simple. Further, since there is no need to perform the mounting operation from the inside of the apparatus main body, there is an advantage that no space is required for the mounting portion of the apparatus and the apparatus can be downsized.
[0011]
FIG. 3 shows a cable hanger mounting device according to a second embodiment of the present invention. The shaft of the mounting hole 23a of the main body 23 in the first embodiment, that is, the mounting shaft h is connected to the cable on the front side of the main body. It is formed to be inclined toward the fixed position A of the hanger. With such a structure, even when the hook portion 21g of the cable hanger 21 is located at a position other than the fixed position A when the cable hanger 21 is attached (shown by a broken line), the weight of the hook portion 21g is reduced. G generates a rotational torque i on the mounting shaft h, and brings the hook portion 21g to the fixed position A. Therefore, the cable hanger can always be arranged at a position where it does not interfere when not in use.
[0012]
【The invention's effect】
The cable hanger mounting device of the present invention includes a cable hanger, a bush into which the tip of the cable hanger is inserted, and a mounting hole on the main body side of the device into which the bush is inserted. When the cable hanger is inserted into the bush in a state where the bush is inserted into the mounting hole, the bushing has a device that is larger than the shape of the mounting hole and engages with the distal end of the cable hanger. Therefore, according to the present invention, since no ball plunger, screw or the like is used, the number of parts required for mounting is small, and the work at the time of mounting is simple. Further, since there is no need to perform the mounting operation from the inside of the apparatus main body, there is an advantage that no space is required for the mounting portion of the apparatus and the apparatus can be downsized.
[0013]
Further, the axis of the cable hanger mounting hole is inclined toward the fixed position of the cable hanger, so that the cable hanger is configured to always be located at the fixed position by using its own weight. In addition, the cable hanger can always be arranged at a position where it is not in the way when not in use. Therefore, it is possible to obtain an effect of preventing the cable hanger from rotating freely and coming into contact with a wall or the like due to vibration during movement of the product.
