Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an anti-falling mechanism for a tube holding component of an X-ray machine. Background Art
[0002] An X-ray machine is a device that can generate X-rays. Mobile X-ray machines are indispensable mobile medical equipment in hospitals. Mobile DR is needed in emergency rooms and wards to take X-rays of patients. Therefore, a mobile DR device that is flexible, powerful in taking X-rays, and can move freely in narrow wards is what hospitals need. Existing mobile X-ray anti-fall devices are roughly divided into: double wire rope ratchet pawl structure, trapezoidal screw plus safety nut structure, and block rack structure. However, these structures are complex and costly, and are difficult to implement in some space-constrained situations, and are difficult to meet the structural requirements of modern X-ray machines. Utility Model Content
[0003] In order to solve the technical problems existing in the prior art, the utility model provides an anti-falling mechanism for a tube holding assembly of an X-ray machine, which relies on a reasonable mechanical layout to prevent the tube holding mechanism from falling, has a simple structure and high safety performance.
[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an anti-fall mechanism for a tube holding assembly of an X-ray machine, comprising a vertically arranged column, a tower wheel is installed on the top of the column, a height scale is pasted on the bottom of the column, the height scale is arranged along the height direction of the column, and the height scale is used to indicate the height of the tube holding mechanism.
[0005] A plurality of guide rails are arranged on the column along the height direction of the column, and the guide rails are fixed on the column by a plurality of locking nails.
[0006] A barrel holding mechanism is mounted on the column, and a plurality of slide grooves are arranged in the barrel holding mechanism. The number of the slide grooves is the same as the number of the guide rails. Each slide groove is correspondingly installed on the guide rail. The slide groove matches the guide rail, and the guide rail plays a guiding role in the linear motion of the barrel holding mechanism.
[0007] The utility model also includes an anti-falling plate, which is composed of an upper connecting plate and a lower connecting plate. A bending portion is formed at the connection between the upper connecting plate and the lower connecting plate, and a 120-degree angle is formed between the upper connecting plate and the lower connecting plate. The bending portion is rotatably mounted on the cylinder holding mechanism through a rotating shaft, and the anti-falling plate can rotate around the rotating shaft at a certain angle. The top of the upper connecting plate is connected to one end of the wire rope, and the other end of the wire rope is wound around the tower wheel. The bottom of the lower connecting plate is arranged with anti-slip grooves.
[0008] The utility model also comprises a strip brake plate, which is fixed on the column through a plurality of anti-fall screws. The anti-fall screws can limit the extreme falling position of the holding tube assembly, so as to achieve double protection.
[0009] The utility model also includes a spring, one end of which is connected to the upper connecting plate by a positioning screw, and the other end of the spring is sleeved on a core shaft, which is arranged perpendicular to the rotating shaft and is threadedly connected to the barrel holding mechanism. Under normal circumstances, the spring is in a compressed state. Once the wire rope breaks, the spring springs outward and releases its elastic force, and the anti-falling plate rotates around the rotating shaft under the action of the spring. The anti-slip pattern at the bottom of the lower connecting plate abuts against the strip brake plate to prevent the barrel holding mechanism from falling.
[0010] Among them, the bottom end of the wire rope passes through the rope hole of the anti-fall plate and is locked by a wire lock buckle. The wire lock buckle is composed of two wire pressure plates, and the two wire pressure plates are locked by bolts and nuts.
[0011] A top cap is installed on the top of the column, and the tower wheel is placed in the top cap to protect the tower wheel structure.
[0012] Compared with the prior art, the utility model has the following beneficial effects: the weight of the cylinder holding mechanism is balanced by the steel wire rope and the spring. When the steel wire rope breaks due to long-term use or accidental breakage, the spring originally in the compressed state springs outward, and the anti-falling plate rotates around the rotating shaft. Due to the eccentric structure of the anti-falling plate, the anti-slip pattern at the bottom of the anti-falling plate presses against the strip brake plate and locks, and the cylinder holding mechanism will not continue to fall, thus preventing accidents. The anti-falling mechanism has a simple structure, and the anti-falling plate, strip brake plate and spring are all placed on the original X-ray machine mechanism, without the need to expand the mechanism range too much. The structure is simple, the installation is convenient, the cost is low, and the operation is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Along the height direction of the column 1 , a plurality of guide rails 4 are arranged on the column 1 , and the guide rails 4 are fixed on the column 1 by a plurality of locking pins 5 .
[0021] A tube-holding mechanism 6 is mounted on the column 1, and a plurality of slide grooves are arranged inside the tube-holding mechanism 6. The number of the slide grooves is the same as the number of the guide rails 4. Each slide groove is correspondingly installed on the guide rail 4. The slide groove matches the guide rail 4. The guide rail 4 guides the linear motion of the tube-holding mechanism 6. The tube-holding mechanism 6 can reciprocate up and down along the guide rail 4.
[0022] like Figure 4 As shown, the utility model also includes an anti-falling plate 7, which is composed of an upper connecting plate 71 and a lower connecting plate 72. A bending portion 73 is formed at the connection between the upper connecting plate 71 and the lower connecting plate 72, and a 120-degree angle is formed between the upper connecting plate 71 and the lower connecting plate 72. The bending portion 73 is rotatably mounted on the cylinder holding mechanism 6 through a rotating shaft, and the anti-falling plate 7 can rotate around the rotating shaft by a certain angle. The top of the upper connecting plate 71 is connected to one end of the wire rope 8, and the other end of the wire rope 8 is wound around the tower wheel 2. The bottom of the lower connecting plate 72 is arranged with anti-slip grooves.
[0023] The utility model also includes a strip brake plate 10, the outer side of which is arranged with anti-slip grooves. The strip brake plate 10 is fixed to the column 1 by a plurality of anti-fall screws 11. The anti-fall screws 11 can limit the extreme falling position of the clamping tube assembly to achieve double protection and minimize the probability of injury to the patient as much as possible.
[0024] The utility model also includes a spring 9, one end of which is connected to the upper connecting plate 71 by a positioning screw, and the other end of the spring 9 is sleeved on a core shaft, which is arranged perpendicular to the rotating shaft, and the core shaft is threadedly connected to the tube holding mechanism 6; under normal circumstances, the spring 9 is in a compressed state. Once the wire rope 8 breaks, the spring 9 bounces outward and releases the elastic force, and the anti-fall plate 7 rotates around the rotating shaft under the action of the spring 9, and the anti-slip pattern at the bottom of the lower connecting plate 72 abuts against the strip brake plate 10 to prevent the tube holding mechanism 6 from falling.
