Description

Technical Field

[0001] The utility model belongs to the technical field of X-ray blocking equipment, and in particular relates to an X-ray baffle mechanism. Background Art

[0002] X-rays are electromagnetic waves with a very short wavelength, ranging from 10nm to 0.1nm. They have great penetrating power, can sensitize photographic films, make certain substances fluoresce, and can free gases. They have a strong destructive effect on body cells. X-rays are widely used in clinical diagnosis and treatment. The wavelength of X-rays used in diagnosis is 0.08-0.31 angstroms (angstroms A=10-8cm). For example: X-ray chest fluoroscopy, photography, abdominal plain film and other examinations. The existing X-ray baffle drives the tungsten baffle to move up and down through the electromagnet attraction, which is used to block the X-ray radiation on the beam channel during the rear-end maintenance of the X-ray equipment.

[0003] In the existing X-ray baffle structure, the electromagnet is of the power-off attraction type. When the electromagnet encounters a fault or power failure, the block driven by the electromagnet blocks the beam channel. Since the reset spring is prone to abnormal force after long-term use, it is easy to cause the tungsten block to fail to stably reach the corresponding position, which is not convenient for subsequent overall blocking of X-rays. Therefore, an X-ray baffle mechanism is needed to assist in solving this problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] This specific embodiment is an X-ray baffle mechanism, such as Figure 1 and Figure 2As shown, the X-ray baffle mechanism includes a mounting box 1, the interior of the mounting box 1 is hollow to form a accommodating cavity, a mounting tube is arranged on one side of the mounting box 1, a through cavity for X-rays to pass through is arranged at the mounting tube corresponding to the mounting tube of the mounting box 1, and a ray hole 5, a sealing plate 2 is fixed to the other side of the mounting box 1 by bolts, a mounting seat 3 is installed on the sealing plate 2 for the outer side of the mounting box 1, and a conductive plug 4 is installed on the mounting seat 3.

[0027] Reference Figure 2 and Figure 3 As shown, a fixing seat 15 is installed in the accommodating cavity by bolts, and the fixing seat 15 is an L-shaped plate structure. The fixing seat 15 is installed with a blocking component 6, and the blocking component 6 includes a mounting platform 7 installed on the fixing seat 15, and an electromagnetic adsorption component 8 is installed at the top of the mounting platform 7. A mounting rod is arranged at the top of the electromagnetic adsorption component 8, and a blocking plate 13 for auxiliary shielding is installed at the top of the mounting rod. A tungsten block 131 is embedded and installed at the blocking plate 13 corresponding to the ray hole 5, and an ejection spring 14 supported by the auxiliary mounting rod is installed on the mounting rod.

[0028] The above-mentioned electromagnetic adsorption component 8 includes an installation box 9 installed in the installation platform 7. The interior of the installation box 9 is hollow and forms a magnetic absorption cavity. The magnetic absorption cavity is respectively provided with a first electromagnetic block 10 and a second electromagnetic block 11 from top to bottom. The mounting rod is fixed at the top of the first electromagnetic block 10. Through the set electromagnetic adsorption component 8, it can be ensured that the position of the ray hole 5 can be stably opened for work when the power is on, and it can be ensured that the ray hole 5 can be stably blocked when the power is off.

[0029] A limit plate 12 is installed in the accommodating cavity inside the installation box 1 by bolts, and the cross section of the limit plate 12 is L-shaped. One end of the blocking plate 13 extends into the limit plate 12, and a scale plate 121 is embedded and installed on the outer edge of the limit plate 12, and scale lines are engraved on the scale plate 121.

[0030] By setting the limit plate 12, it can be ensured that the blocking plate 13 can be stably fitted on the installation box 1 during the up and down movement, and rotational misalignment of the blocking plate 13 can be avoided as much as possible. By setting the scale plate 121, the overall adjustment position of the blocking plate 13 can be effectively determined during the overall height adjustment of the blocking assembly 6.

[0031] Reference Figure 3 and Figure 4As shown, a fine-tuning bin is provided on the fixed seat 15, and an adjusting component 16 for assisting in fine-tuning the height of the blocking component 6 is installed in the fine-tuning bin. The adjusting component 16 includes a worm gear 19 rotatably embedded in the fine-tuning bin, and an adjusting rod 20 is vertically fixed at the bottom center of the blocking component 6. The adjusting rod 20 is penetrated and installed on the worm gear 19, and the worm gear 19 and the adjusting rod 20 are threadedly matched. A worm 18 is penetrated and installed on the fixed seat 15, and the worm 18 and the worm wheel 19 are matched for transmission. A fixing rod is laterally protruding in the fine-tuning bin, and the worm 18 extends into the fixing rod, and an adjusting bolt 17 is fixed to one end of the worm 18.

[0032] By means of the adjustment assembly 16 arranged on the fixing seat 15, the adjustment bolt 17 is rotated, and the adjustment bolt 17 drives the worm 18 to rotate, and the worm 18 cooperates with the worm wheel 19 to rotate the worm wheel 19 as a whole, and the worm wheel 19 is threadedly matched with the adjustment rod 20, so that the adjustment rod 20 moves as a whole, and then the overall height of the blocking assembly 6 is finely adjusted to ensure that the tungsten block 131 is stably fitted on the ray hole 5, and the ray hole 5 is stably covered at the corresponding position, and when the ejection spring 14 is subjected to abnormal force, the blocking plate 13 can be conveniently adjusted to improve the overall applicability of the device.

[0034] Working principle:

[0035] When it is necessary to fine-tune the height of the blocking plate 13, the adjusting bolt 17 is rotated, and the adjusting bolt 17 drives the worm 18 to rotate. The worm 18 and the worm wheel 19 cooperate with each other to rotate the worm wheel 19 as a whole. The worm wheel 19 and the adjusting rod 20 are threadedly matched, so that the adjusting rod 20 moves as a whole, and then the overall height of the blocking assembly 6 is fine-tuned to ensure that the tungsten block 131 is stably fitted on the ray hole 5 and the ray hole 5 is stably covered.

[0036] During operation, the first electromagnetic block 10 and the second electromagnetic block 11 are powered on, and the first electromagnetic block 10 and the second electromagnetic block 11 are attracted to each other and the first electromagnetic block 10 is lowered as a whole. In the process of the first electromagnetic block 10 being lowered, the mounting rod is driven to be lowered as a whole, and the blocking plate 13 is moved downward as a whole. In the process of the blocking plate 13 being lowered, the ejection spring 14 is driven to be compressed as a whole, so that the tungsten block 131 is disengaged from the ray hole 5, and then the X-rays can be emitted through the ray hole 5. When the power is off, the first electromagnetic block 10 and the second electromagnetic block 11 have no magnetic force due to the power off, and under the action of the ejection spring 14, the blocking plate 13 is driven to cover the ray hole 5, thereby blocking the X-rays.
