Description

[0001] The present application relates to the technical field of endoscopes, in particular to a rotating shaft anti-loose structure, a display device and an endoscope system. BACKGROUND

[0002] An endoscope system is a commonly used medical instrument. When in use, an endoscope is inserted into a patient's body through a natural orifice or a surgically formed incision. After the endoscope is introduced into an organ to be detected, a doctor can directly view the image of the lesion of the relevant part on the display screen of the main machine, so as to make a medical diagnosis.

[0003] In order to obtain a clear and intuitive image of the lesion site and improve the accuracy of the diagnosis of the lesion, an operator sometimes needs to adjust the angle of the display screen to obtain the best image observation angle. Currently, the display screen with adjustable angle is generally installed and fixed by an adjustable support. Whether the fixing of the rotating shaft of the adjustable support is firm determines the stability of the display screen during the turning process. Generally, the rotating shaft is directly fixed with the support during design. However, during the turning process of the display screen, the rotating torque borne by the support is large, and after a certain period of use, the rotating shaft will gradually loosen, thereby easily causing the display screen to vibrate and other adverse phenomena, affecting the operation and use of the display screen.

The end of the sleeve portion 42 in the length direction of the rotating shaft 20 is provided with an end plate 421, the end plate 421 is provided with a fixing hole 422 matched with the outer circumferential surface of the rotating shaft 20, and one end of the rotating shaft 20 is arranged in the fixing hole 422 and is attached to the hole wall of the fixing hole 422. In this way, the sleeve portion 42 can wrap one end of the rotating shaft 20 through the fixing hole 422, and the fixing area and the force point of the rotating shaft 20 are increased, so as to be able to share the torque generated by the rotating shaft 20 when the rotating support 30 is turned over.

[0045] Further, in combination with FIG. 4 and FIG. 5, the support 12 comprises a first support plate 121 and a second support plate 122, the first support plate 121 is connected with the fixing seat 11 and adheres to the inner wall of the end plate 421, the second support plate 122 adheres to the outer wall of the end plate 421, the mounting hole is arranged on the second support plate 122, the anti-loose structure of the rotating shaft further comprises a connecting piece, the connecting piece is arranged through the first support plate 121, the end plate 421 and the second support plate 122 and fixes the first support plate 121, the end plate 421 and the second support plate 122. In this way, the support 12 is connected and fixed with the sleeve part 42, further increasing the stability of the fixing support 10 and the auxiliary sleeve 40. Exemplarily, the connecting piece can be a fall-resistant screw. Further, the first support plate 121 and the fixing seat 11 can be an integrally formed structure, for example, the first support plate 121 and the fixing seat 11 can be integrally bent and formed by sheet metal parts.

[0046] Continuing to refer to FIG. 8, the outer wall of the end plate 421 is provided with a receiving groove 423, and the second support plate 122 is embedded in the receiving groove 423, so that the sleeve part 42 can also wrap around the outer periphery of the second support plate 122, thereby further improving the connection stability of the sleeve part 42 and the second support plate 122. The number of supports 12 is two, the two supports 12 are arranged at intervals on the fixing seat 11, the number of rotating shafts 20 is two, the two rotating shafts 20 are arranged one by one through the mounting holes of the two supports 12, the rotating bracket 30 comprises two legs 31, the two legs 31 are arranged one by one in corresponding with the two rotating shafts 20, and the two ends of the auxiliary sleeve 40 are arranged one by one on the two rotating shafts 20. In this way, it is ensured that the display screen 50 is balanced when rotating, and the stability of the display screen 50 is further improved.

[0047] Referring to FIG. 5, the rotating bracket 30 is rotatably sleeved on the rotating shaft 20, and the anti-loose structure of the rotating shaft further comprises a limiting baffle 61, a friction pad 62 and a locking nut 63.

The friction pad 62 can be pressed against the rotating bracket 30 by the locking nut 63, and the display screen 50 can be suspended at any angle by using the friction between the friction pad 62 and the rotating bracket 30. When it is necessary to adjust the angle of the display screen 50, the display screen 50 or the rotating bracket 30 is rotated by force, and when the force applied to the display screen 50 or the rotating bracket 30 is greater than the friction between the friction pad 62 and the rotating bracket 30, the display screen 50 can be rotated, thereby adjusting the angle of the display screen 50. Exemplarily, the number of friction pads 62 is multiple, and the multiple friction pads 62 are arranged along the axial direction of the rotating shaft 20, thereby improving the stability of the locking rotating bracket 30.
