Description

Technical Field

[0001] The utility model relates to the technical field of angiography equipment, in particular to an anti-collision device for angiography equipment. Background Art

[0002] The detector assembly is the main component required for angiography imaging. When the patient needs angiography, the detector assembly needs to move frequently. During the movement, it will touch the patient or the bed. The detector assembly installation structure generally has a certain anti-collision function. During angiography, when the detector assembly moves to the required position, it touches the patient or the bed board and the anti-collision function is activated, which is a protection function for the detector assembly and the patient.

[0003] The traditional anti-collision device structure is a spring connecting the sensing shell of the detector assembly. The spring needs to overcome the deadweight of the sensing shell of the anti-collision device. The required elastic force of the spring is relatively large, resulting in the anti-collision device having problems such as large triggering force and insensitive triggering. Utility Model Content

[0004] 1. Technical issues

[0005] The utility model aims to provide an anti-collision device for angiography equipment, so as to solve the problem in the prior art that the triggering of the induction housing is not sensitive and a large triggering force is required.

[0017] (III) Beneficial effects

[0018] By adjusting the position of the counterweight on the balance link, the sensing housing forms a balanced state relative to the base within a certain distance range. When the entire anti-collision device approaches the detection part or collides with other objects, the balance is destroyed due to the external force generated by the sensing housing, so that the sensing housing can move relative to the base, which is convenient for quickly triggering the internal sensor through the sensing housing to achieve the stopping or retraction of the entire anti-collision device.

[0019] Since a lever-type balance is formed between the counterweight and the sensing housing, the sensing housing can be sensitively moved toward the base when the balance is broken even by a very small external force, thereby improving the sensitivity of detection;

[0020] Moreover, when the sensing shell is subjected to force, the balance will be destroyed. The force direction of the sensing shell is not limited to a specific direction, which improves the consistency of different force directions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figure 1-Figure 3 As shown, in the embodiment of the utility model, an anti-collision device for angiography equipment is proposed, which is applied to the detector in the angiography equipment. After the anti-collision device contacts the human body or other objects, a feedback signal is generated to stop or retract, thereby realizing the purpose of positioning or protecting the detector. Specifically, it includes a base 2 and a sensing shell 1, at least one balancing mechanism and an elastic reset component are arranged between the sensing shell 1 and the base 2; the balancing mechanism includes a first connecting seat 8 fixedly connected to the base 2 and a second connecting seat 9 fixed to the sensing shell 1, a transverse connecting rod 4 is rotatably installed on the first connecting seat 8, a counterweight 3 is slidably installed on one end of the transverse connecting rod 4, and a longitudinal connecting rod 5 is connected to the other end of the transverse connecting rod 4, and the longitudinal connecting rod 5 is connected to the second connecting seat 9, and the elastic reset component is connected to the first connecting seat 8 and the second connecting seat 9; the transverse connecting rod 4 is used as a lever, one end of which is adjusted by sliding the counterweight 3, and the other end is connected to the sensing shell 1 through the longitudinal connecting rod 5, and the relative position of the counterweight 3 is adjusted to keep the sensing shell 1 balanced at a certain distance relative to the base 2, that is, by adjusting the position of the counterweight 3, the spacing of the sensing shell 1 relative to the base 2 when it is in a balanced state can be adjusted; after the sensing shell 1 is subjected to an external force, it will become unbalanced and move toward the base 2, so as to trigger the pre-installed sensor inside, thereby realizing signal feedback. Since the sensing housing 1 is in balance with the counterweight 3 when in a balanced state, once the sensing housing 1 is subjected to a force, it can move sensitively, and can achieve stopping and collision prevention in time, and the sensitivity is improved.

[0028] After the imbalance occurs, the induction housing 1 is reset by the elastic reset component during reset and the counterweight 3 and the induction housing 1 are balanced again after a certain period of time.

[0029] Specifically, a transverse adjustment hole 10 is opened on the transverse connecting rod 4, and a locking piece 11 for fastening the counterweight 3 is installed on the transverse adjustment hole 10. The counterweight 3 is locked after the position is moved by the relative movement of the locking piece 11 in the transverse adjustment hole 10. At the same time, the position of the counterweight 3 is adjusted to achieve a new balance when the spacing distance between the sensing housing 1 and the base 2 changes.

[0030] In order to guide the counterweight block 3 when it slides on the cross-link 4, a sliding groove 12 is opened on the counterweight block 3, and the cross-link 4 slides in cooperation with the sliding groove 12. Through the sliding cooperation between the sliding groove 12 and the cross-link 4, a guiding effect is formed on the counterweight block 3 during the sliding process, thereby ensuring the stable sliding of the counterweight block 3.

[0031] At the same time, an inclined surface structure 13 is provided on the end of the counterweight block 3 away from the first connecting seat 8. The inclined surface structure 13 allows the counterweight block 3 to play an evasive role during assembly to avoid contact and collision with other components.

[0032] Specifically, each time an unbalanced state is generated between the sensing housing 1 and the counterweight 3, a quick reset is required, and the initial state of the sensing housing 1 is adjusted by an elastic reset component, wherein the elastic reset component includes a slide rod 6 slidably mounted on the first connecting seat 8, the lower end of the slide rod 6 passes through the end of the second connecting seat 9 and is provided with a locking block 18, and a spring 7 is sleeved on the slide rod 6. After the first connecting seat 8 and the second connecting seat 9 are connected by the slide rod 6, when the sensing housing 1 moves relative to the base 2, the second connecting seat 9 and the slide rod 6 can also slide relative to the first connecting seat 8, and the reverse force generated by the compression of the spring 7 is used to push the sensing housing 1 in the opposite direction to achieve reset. During the reset process, since the spring 7 has no elastic force after reset, the sensing housing 1 is reset to the initial position to form a new balanced state with the counterweight 3, and the reset process is completed.

[0033] At the same time, a guide portion 14 extending toward the second connecting seat 9 is provided on the first connecting seat 8, and an adjusting nut 15 is threadedly connected to the guide portion 14. The spring 7 abuts against the adjusting nut 15. The sliding of the slide rod 6 is guided by the guide portion 14 to achieve a longer distance of sliding, thereby ensuring stability. At the same time, the compression length of the spring 7 is adjusted by the adjusting nut 15, so as to match the distance adjustment between the sensing housing 1 and the base 2 after the counterweight block 3 is adjusted.

[0034] At the same time, a mounting hole coaxial with the guide portion 14 and a guide sleeve 16 arranged in the mounting hole are opened on the first connecting seat 8. The guide sleeve 16 is provided to facilitate the installation of the slide rod 6 and consider the limitation of the head of the slide rod 6.

[0035] At the same time, a limiting groove 17 for limiting the rotation of the locking block 18 is provided on the second connecting seat 9. The cross-section of the locking block 18 is polygonal. A non-rotating fit is formed between the locking block 18 and the limiting groove 17, so that when the sliding rod 6 is adjusted, the locking block 18 does not need to be limited by additional tools.

[0036] Specifically, a gasket 19 is provided between the head of the slide rod 6 and the guide sleeve 16 and between the locking block 18 and the limiting groove 17. The gasket 19 is sleeved on the slide rod 6. The gasket 19 is used to buffer the relative collision positions to form protection.
