Problems solved by technology

It has the following problems: 1. The rotating shaft connecting the caster and the trolley frame does not pass through the center of the caster, which causes the trolley to be adjusted in the forward and backward direction first, and then to the left and right. Adjust the position of the trolley internally; 2. The brakes on multiple casters need to be locked one by one to realize the fixation of the trolley. The locking action is complicated, and it is not easy to step on the brakes in a small space; 3. In the flatness When moving on poor ground, the trolley will generate large vibrations, which is not good for the equipment on the trolley

Embodiment 1

[0026] like figure 1 The caster shown includes a support base 1, and the middle part of the support base 1 is provided with a vertically penetrating installation hole 2, and a rolling ball 3 is provided in the installation hole 2, and the diameter of the rolling ball 3 is slightly smaller than that of the installation hole 2. Aperture, the thickness of the support seat 1 is about 1 / 3 of the diameter of the ball 3, and the lower part of the support seat 1 is provided with a limit stop edge 4 for preventing the ball 3 from falling out of the lower end of the installation hole 2. The limit stop edge 4 It is annular and arranged coaxially with the mounting hole 2 , the diameter of the hole surrounded by the limit stop edge 4 is smaller than the diameter of the rolling ball 3 , and the ball center of the rolling ball 3 is higher than the limit stop edge 4 .

[0027] like figure 1 As shown, the supporting seat 1 is provided with a connecting seat 5 acting on the rolling ball 3 to p...

Embodiment 2

[0033] The structural principle of this embodiment is basically the same as that of Embodiment 1, the difference is that there are a number of vertically arranged connecting holes 6 on the connecting base 5, and the number of connecting holes 6 is fixed on the supporting base 1. Corresponding to the connecting column 7, the connecting column 7 is pierced in the corresponding connecting hole 6, and the upper end of the connecting column 7 is provided with a limit flange 8 whose outer diameter is larger than that of the connecting hole 6. Wherein, the connecting holes 6 are distributed in a circular array along the centerline of the mounting holes 2 .

Embodiment 3

[0035] like image 3 The shown endoscope trolley includes a trolley frame 14, the bottom of the trolley frame 14 is provided with four casters as described in Embodiment 1 or Embodiment 2, and between each caster and the trolley frame 14 A damper 15 attenuates the vibration and acts as a shock absorber.

[0036] like image 3 As shown, a power supply 16 is provided on the trolley frame 14, and the power supply 16 is an uninterruptible power supply 16 (UPS), which can provide power for equipment placed on the trolley, such as an image processor and a cold light source, and simultaneously provide power for the drive in the casters. Components provide power. A locking / unlocking button is provided on the trolley frame 14 for controlling the driving components in the casters.

[0037] When the lock / unlock button is stepped on to the unlocked position, the power supply 16 supplies power to the first electromagnetic coil 9 and the second electromagnetic coil 10, and the magnetic f...

Abstract

The invention provides a caster and an endoscope trolley, belonging to the technical field of medical instruments. The utility model solves the problem that the existing trolley has adjustment displacement when turning and is unfavorable for adjusting the position of the trolley in a narrow space. The caster includes a support seat, which has a vertical installation hole, and a rolling ball is arranged in the installation hole, and the lower part of the support seat is provided with a limit stop for preventing the ball from falling out of the lower end of the installation hole. , the support seat is provided with a connecting seat acting on the rolling ball to prevent the rolling ball from coming out of the upper end of the mounting hole, and the lower part of the rolling ball protrudes from the lower end of the mounting hole under the action of the connecting seat; the endoscope trolley Includes trolley frame and casters as mentioned above. The casters in the invention can be turned immediately, so that the trolley does not produce adjustment displacement when turning; locking and unlocking can be completed with only one operation action; and the shock absorption effect is good.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to a caster and an endoscope trolley. Background technique [0002] The trolley is used to carry medical equipment and is widely used in the medical field. The Chinese patent discloses a novel trolley [authorized announcement number is CN203220441U], comprising a trolley frame, the bottom of the trolley frame is provided with casters, and the casters are provided with brakes. It has the following problems: 1. The rotating shaft connecting the caster and the trolley frame does not pass through the center of the caster, which causes the trolley to be adjusted in the forward and backward direction first, and then to the left and right. It is not conducive to the adjustment of the trolley in a small space Adjust the position of the trolley internally; 2. It is necessary to lock the brakes on multiple casters one by one to realize the fixation of the trolley. The locking action ...
