Description

Installation mechanism, protector and medical imaging equipment

Technical Field

The invention relates to the technical field of medical instruments, in particular to an installation mechanism, a protection device and medical imaging equipment.

Background

Medical imaging equipment such as CT (Computed Tomography) utilizes a housing and a frame to cooperate to form a protective space for protecting components (e.g., electrical components such as detection components, control components, and circuit boards). The housing includes a plurality of shells that cooperate with one another to form a unitary body. At present, two adjacent outer covers need to be closely connected to achieve the dustproof and waterproof protection effect. And for convenient maintenance, be convenient for open the guard space, partial dustcoat is for rotating the connection setting to utilize locking mechanism to lock and open. The enclosure can be flipped up relative to the top enclosure as before, thereby opening the protected space.

Because the outer covers are closely connected, when the outer covers are opened, the side walls of the outer covers are easy to scrape and touch the side walls of the adjacent outer covers in the rotating process of the outer covers. In order to avoid the scraping phenomenon, the traditional solution needs to arrange an independent avoiding mechanism at the position where collision is easy to occur. Due to the arrangement of the avoiding mechanism, the outer cover needs to be pulled outwards firstly and then rotates in the unlocking process; the locking process is reversed. This results in an excessively cumbersome operation of opening and closing the housing.

Brief description of the drawingsthe accompanying drawings, which form a part hereof, are provided to provide a further understanding of the present application, and are included to explain an illustrative embodiment of the present application and a description thereof and are not to be construed as limiting the present application.

In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings needed to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present application, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without creative efforts.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the scope of the disclosure, are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application.

The conventional medical imaging apparatus, as a common medical instrument, occupies an important position in the field of in vitro diagnosis, and also brings a lot of help for medical progress. The brand of the medical imaging equipment is various at present, so that a plurality of products can be selected by hospitals, the favor of the hospitals can be obtained, and the competitiveness of the products is improved and more emphasized by medical imaging equipment manufacturers. Among medical imaging equipment products with similar functions or performances, the more beautiful the appearance of the medical imaging equipment is, the more popular the medical imaging equipment is in hospitals. Therefore, how to improve the aesthetic feeling of the appearance of the medical imaging equipment becomes a problem that manufacturers of the medical imaging equipment attach more and more importance to the aesthetic feeling.

At present, the shell of the medical imaging equipment is often matched with a rack to form a protection space of an element, and in order to conveniently open the protection spaces of different parts, the shell is generally formed by splicing a plurality of outer covers, and when maintenance is carried out, only the outer cover corresponding to the protection space needs to be opened. For the aesthetic appearance and the protection effect of the medical imaging device, the two adjacent outer covers need to be tightly connected. However, because the outer covers are tightly connected, when the outer covers are opened, the side walls of the outer covers are easy to scrape against the side walls of the adjacent outer covers in the rotating process of the outer covers. In order to avoid scraping and colliding, the traditional solution scheme needs to be provided with an independent avoiding mechanism at a position where collision easily occurs, so that the opening and closing operations of the outer cover are too complex, and the improvement of user experience is not facilitated.

Therefore, there is a need for a mounting mechanism for mounting a housing, which can simplify the opening and closing operations of the housing and is beneficial to improving the user experience.

As shown in fig. 1 to 3, in one embodiment, the mounting mechanism includes a fixed member 100, a connecting member 200, a sliding member 300, a rotating member 400 and a transmission unit 500, wherein the connecting member 200 is fixedly connected to the fixed member 100, the sliding member 300 is slidably connected to the connecting member 200, and the sliding member 300 has a first position disposed close to the fixed member 100 and a second position disposed far from the fixed member 100; the rotating member 400 is rotatably connected with the sliding member 300, the rotating member 400 has a first rotating position and a second rotating position, and the transmission unit 500 is disposed between the rotating member 400 and the sliding member 300; when the rotating member 400 rotates from the second rotating position to the first rotating position, the rotating member 400 can drive the sliding member 300 to move to the first position through the transmission unit 500; when the rotation member 400 is in the first rotation position, the transmission unit 500 is in a locked state such that the slider 300 is fixed in the first position; when the rotation member 400 rotates from the first rotation position to the second rotation position, the transmission unit 500 is in the unlocked state, and the slider 300 can be automatically reset from the first position to the second position.

Thus, the sliding member 300 is automatically reset, so that the sliding member 300 can automatically move from the first position to the second position, and the transmission unit 500 is driven to reset. At this time, the rotating member 400 is disposed on the sliding member 300, so that in the process of rotating the rotating member 400 from the first rotating position to the second rotating position, an avoiding space is formed away from the fixing member 100 to avoid interference, and further, the avoiding space can be generated only by rotating the rotating member 400, thereby reducing the operation steps and simplifying the operation process; meanwhile, the rotation member 400 is engaged with the transmission unit 500 to lock and unlock the sliding member 300.

It should be noted that the "automatic reset" that the sliding member 300 can be automatically reset from the first position to the second position "may be implemented by any existing technology that meets the use requirement, such as elastic reset (spring, elastic sheet, elastic glue, air spring, etc.), gravity automatic reset (counterweight mechanism, etc.), or magnetic automatic reset (magnet, electromagnet, etc.).

In addition, the "sliding member 300" may directly or indirectly achieve "automatic reset", that is, the reset member may be disposed between the sliding member 300 and the fixed member 100, or between the "transmission unit 500" and the sliding member 300, the fixed member 100, or the rotating member 400, and the "transmission unit 500" is automatically reset to drive the "sliding member 300" to reset.

It should be noted that the "transmission unit 500" may be implemented in various manners as long as it can convert the rotation power of the rotation member 400 into the force for driving the sliding member 300 to move to the first position and lock the sliding member 300 at the first position; after the rotating power of the rotating member 400 is removed, the sliding member 300 may be reset, including but not limited to a sliding block transmission, a rack and pinion 530 transmission, a lead screw 560 nut 550 transmission, and the like. And the transmission cooperation manner of the "transmission unit 500" and the "sliding member 300" or the "rotating member 400" may be various as long as the above-mentioned force conversion can be realized.

Further, the "transmission unit 500 is in the locked state" means that the transmission unit 500 does not perform transmission, thereby restricting the return movement of the slider 300. The "transmission unit 500 is in the unlocked state" means that the transmission unit 500 can perform transmission without restricting the reset movement of the slider 300.

For a better understanding of the mounting mechanism of the present application, a medical imaging device is described that employs the mounting mechanism.

As shown in fig. 1 to 3 and 12 to 14, in one embodiment, a medical imaging apparatus is provided, which includes a protection device 10 and a frame 20; the guard 10 includes the mounting mechanism 12 and the first housing 14 described above. Wherein, the top of the frame 20 is provided with a second housing 22, the mounting mechanism 12 is installed on the inner side wall of the first housing 14 through the rotating member 400, and the fixing member 100 is fixedly connected with the frame 20 or the second housing 22, so that the first housing 14 is installed on the side of the frame 20 through the fixing member 100; and the rotary member 400 is in the first rotary position, the top side of the first housing 14 is in sealing engagement with one side of the second housing 22.

When the medical imaging device is used, when the first housing 14 needs to be opened, only the first housing 14 needs to be rotated, and the rotating member 400 is driven by the first housing 14 to rotate from the first rotating position to the second rotating position (as shown in fig. 14 to 17 or 18); at this time, the transmission unit 500 is unlocked, and then the sliding member 300 can be automatically reset from the first position to the second position, the sliding member 300 drives the rotating member 400 to move away from the fixing member 100, and then the first outer cover 14 can move away from the second outer cover 22, so that an avoidance space is formed between the side wall of the first outer cover 14 and the side wall of the second outer cover 22, and the avoidance space is expanded as the sliding member 300 continues to move towards the second position, thereby further preventing the first outer cover 14 and the second outer cover 22 from being scraped; meanwhile, in the process of resetting the sliding member 300, the transmission unit 500 can be driven to reset. When the first outer cover 14 needs to be closed, the first outer cover 14 is rotated in the reverse direction, the rotating member 400 is driven by the first outer cover 14 to rotate from the second rotating position to the first rotating position, the rotating member 400 drives the sliding member 300 to move towards the first position through the transmission unit 500, until the rotating member 400 rotates to the first rotating position (as shown in fig. 14 and 15), the transmission unit 500 is locked, and the sliding member 300 is fixed at the first position; in this process, the sliding member 300 drives the rotating member 400 to move close to the fixing member 100, and the side wall of the first housing 14 gradually approaches the side wall of the second housing 22 until the two are tightly attached to each other, thereby completing the closing of the first housing 14.

Thus, the medical imaging device employs the mounting mechanism 12, so that the opening and closing operations of the first housing 14 are simple, and an avoidance space can be generated only by unlocking the first housing 14 and then rotating the first housing 14 without interfering with the second housing 22; when the first housing 14 is closed, the first housing 14 can be closed by rotating the first housing 14 in the opposite direction, and the first housing 14 can be tightly attached to the second housing 22. And the operation process does not have the operation of pulling outwards or pushing inwards the first outer cover 14, so that the interference with the movement of the locking mechanism is avoided, and the reliability is higher.

As shown in fig. 12 and 13, when the first housing 14 is a front housing and the second housing 22 is a top housing, the close fit of the two will greatly affect the appearance of the medical imaging apparatus. By using the mounting mechanism 12 of the present application, the first housing 14 and the second housing 22 can be connected tightly, so that the high-grade feeling is increased, and a good waterproof and dustproof effect can be achieved. Meanwhile, when the medical imaging device is a CT machine, the first housing 14 and the second housing 22 are tightly connected to effectively isolate the radiation generated in the protective space, thereby reducing the radiation pollution.

It should be noted that the "second rotation position" is relatively flexible to be selected as long as the slide 300 can be reset to the second position, which includes, but is not limited to, the position shown in fig. 17, the position shown in fig. 18, and any position between the position shown in fig. 17 and the position shown in fig. 18, that is, the "second rotation position" can be selected within a rotation range.

The position shown in fig. 16 and 17 is the "second rotation position" of the rotation member 400, and when the rotation member 400 rotates to the second rotation position (as shown in fig. 16 and 17), the rotation may be continued so that the first cover 14 is opened to the position shown in fig. 18.

It should be noted that the rotating member 400 and the first housing 14 may be mounted in various ways as long as the fixed connection therebetween can be achieved.

In addition, in the embodiment, the fixing member 100 is fixedly connected to the second outer cover 22, and the fixing manner of the fixing member and the second outer cover may be various, and is not limited herein.

On the basis of the above embodiments, as shown in fig. 3 to 6, in an embodiment, the transmission unit 500 includes a transmission member 510 and a connection shaft 520, the transmission member 510 is slidably connected to the sliding member 300, the transmission member 510 is provided with a first sliding rail 512, the connection shaft 520 is slidably engaged with the first sliding rail 512, and the connection shaft 520 is rotatably connected to the connection member 200; the rotating member 400 is in driving engagement with the transmission member 510. When the rotating member 400 rotates from the second rotating position to the first rotating position, the rotating member 400 can drive the sliding member 300 to move to the first position through the transmission member 510; when the rotating member 400 is at the first rotating position, the transmission member 510 is in a locked state, so that the sliding member 300 is fixed at the first position; when the rotating member 400 rotates from the first rotating position to the second rotating position, the transmission member 510 is in the unlocked state, and the sliding member 300 can automatically return from the first position to the second position and drive the transmission member 510 to return.

Thus, a slider transmission manner is formed by the transmission member 510 and the connection shaft 520, that is, the transmission member 510 moves to drive the connection shaft 520 to change the position on the first slide rail 512, so that the shortest distance between the connection member 200 and the transmission member 510 changes, and the rotation power of the rotation member 400 can be converted into the force for driving the movement of the sliding member 300. Specifically, when the first outer cover 14 needs to be closed, rotating the first outer cover 14 drives the rotating member 400 to rotate, so that the rotating member 400 rotates from the second rotating position to the first rotating position; at this time, the rotating member 400 drives the transmission member 510 to move, and the transmission member 510 moves to drive the connecting shaft 520 to change the position on the first sliding rail 512, so that the shortest distance between the connecting member 200 and the transmission member 510 is reduced, and the sliding member 300 is further driven to move toward the first position. When the rotating member 400 is at the first rotating position, the rotating member 400 is not rotating, so that the transmission member 510 is not moving to be at the locking position, and further the sliding member 300 is locked at the first position, thereby achieving the closing of the first housing 14. When the first outer cover 14 needs to be opened, the first outer cover 14 is rotated, the first outer cover 14 drives the rotating member 400 to rotate, the rotating member 400 drives or cancels the pressing on the rotating member 510, so that the driving member 510 can move, further, the sliding member 300 moves from the first position to the second position under the action of the restoring force, the rotating member 400 and the first outer cover 14 are driven to move away from the second outer cover 22, and the driving member 510 moves under the driving of the sliding member 300, so that the position of the connecting shaft 520 on the first sliding rail 512 is changed, and the shortest distance between the connecting member 200 and the driving member 510 is changed.

It should be noted that there are many transmission matching manners of the "transmission member 510" and the "rotation member 400", as long as the transmission member 510 can be driven to move, which includes but is not limited to "connect", "abut", "engage", and the like.

In an embodiment, as shown in fig. 3 and fig. 6, the rotating member 400 is provided with a matching protrusion 410 capable of pressing against the transmission member 510, and the rotating member 400 drives the transmission member 510 to move through the matching protrusion 410; when the rotating member 400 is at the first rotating position, the engaging protrusion 410 presses against the transmission member 510, so that the transmission member 510 is in a locked state. Thus, when the rotating member 400 rotates from the second rotating position to the first rotating position, the predetermined position is reached, the engaging protrusion 410 can press the transmission member 510, and the rotating member 400 continues to rotate to the first rotating position to drive the engaging protrusion 410 to press the transmission member 510 to move, so that the sliding member 300 can move to the first position. When the rotating member 400 rotates from the first rotating position to the second rotating position, i.e. during the process of opening the first housing 14, the engaging protrusion 410 moves along with the rotating member 400 and gradually releases the pressing force on the transmission member 510, so that the sliding member 300 can gradually rotate to the second position; when the engaging protrusion 410 returns to the predetermined position, the engaging protrusion 410 continues to rotate along with the rotating member 400, and the engaging protrusion 410 can be separated from the transmission member 510, so that the transmission member 510 does not interfere with the rotation of the rotating member 400, which is beneficial to ensuring the smooth opening of the first housing 14.

On the basis of any one of the embodiments of the transmission member 510, as shown in fig. 4 and fig. 6, in one embodiment, the sliding member 300 is provided with a second sliding rail 310 slidably connected to the connecting member 200 and a third sliding rail 310 slidably connected to the transmission member 510, and the second sliding rail 310 and the third sliding rail 310 are disposed to intersect each other. In this way, the second slide rail 310 and the third slide rail 310 cooperate to form a cross guide rail, which facilitates converting the movement of the transmission member 510 into the movement of the slider 300.

It should be noted that the specific implementation forms of the "first slide rail 512", the "second slide rail 310" and the "third slide rail 310" may be implemented by various conventional technologies, including but not limited to a strip-shaped groove, a strip-shaped convex body, and the like.

Of course, in other embodiments, the transmission unit 500 may also implement transmission cooperation between the sliding member 300 and the rotating member 400 in other manners.

As shown in fig. 9, in an embodiment, the transmission unit 500 includes a rack 530 and a transmission gear 540 engaged with the rack 530 for transmission, the rack 530 is fixedly connected to the sliding member 300, and the rotation member 400 drives the transmission gear 540 to rotate. Thus, the rotating member 400 can directly or indirectly drive the transmission gear 540 to rotate, and directly engages with the transmission gear 540 to drive the rack 530 to move, or indirectly drive the rack 530 to move, and further the rotating member 400 can be rotated to drive the sliding member 300 to move through the transmission unit 500, that is, the first outer cover 14 can be opened to rotate, and the top side of the first outer cover 14 can be separated from the second outer cover 22, so that the scraping phenomenon is avoided.

Alternatively, as shown in fig. 10 and 11, in another embodiment, the transmission unit 500 includes a nut 550 and a lead screw 560 in screw transmission engagement with the nut 550, the nut 550 is fixedly connected to the sliding member 300, and the rotating member 400 drives the lead screw 560 to rotate through a bevel gear assembly 570 or a worm gear assembly 580. Thus, the rotating member 400 can indirectly drive the screw rod 560 to rotate through the bevel gear assembly 570 or the worm gear assembly 580, and through the matching between the screw rod 560 and the nut 550, the sliding member 300 can move along the axial direction of the screw rod 560, and further the rotating member 400 can be rotated to drive the sliding member 300 to move through the transmission unit 500, that is, the first outer cover 14 can be opened to rotate, and meanwhile, the top side of the first outer cover 14 is separated from the second outer cover 22, so that the scraping phenomenon is avoided.

On the basis of any of the above embodiments, as shown in fig. 1 and fig. 6, in an embodiment, the sliding member 300 is fixedly provided with a sliding strip 600, and the sliding strip 600 is slidably connected with the fixing member 100. Therefore, the sliding strip 600 is in sliding connection with the fixing piece 100, so that the distance sliding connection between the sliding piece 300 and the fixing piece 100 is realized, the stress reliability of the sliding piece 300 is improved through the fixing piece 100, the force transmitted to the fixing piece 100 by the first outer cover 14 through the sliding piece 300 is borne, the stress between the connecting piece 200 and the sliding piece 300 is reduced, the friction force or interference generated when the sliding piece 300 is matched with the fixing piece 100 can be reduced, and the sliding matching between the sliding piece 300 and the connecting piece 200 is ensured to be smooth.

It should be noted that the "sliding member 300" and the "sliding bar 600" may be integrally formed, or may be separately manufactured and then combined together to implement a specific implementation form, which is not limited herein.

In addition, the "rotational connection" between the "rotating member 400" and the "sliding member 300" includes direct and indirect rotational connections, and the specific implementation manner thereof can be flexibly selected, and is not limited herein.

Specifically, in the present embodiment, the sliding member 300 is detachably and fixedly connected to the slide bar 600, and the rotating member 400 is directly and rotatably connected to the slide bar 600, so that the rotating member 400 is indirectly and rotatably connected to the sliding member 300.

On the basis of the above embodiments, as shown in fig. 6 to 8, in an embodiment, the fixing member 100 includes a first sidewall 110 and a second sidewall 120 spaced apart from the first sidewall 110 to form the sliding slot 130, two sets of roller units 610 are disposed on the sliding strip 600 at intervals, one set of roller units 610 disposed close to the fixing member 100 abuts against the first sidewall 110, the other set of roller units 610 disposed far away from the fixing member 100 abuts against the second sidewall 120, and the roller units 610 include at least one roller. Thus, two sets of roller assemblies are arranged at intervals and respectively abut against the first side wall 110 and the second side wall 120, so that the slide bar 600 and the fixing piece 100 are stressed uniformly, the sliding piece 300 moves more stably, and the first outer cover 14 is ensured to be high in moving precision in the opening and closing processes.

In addition to any of the above embodiments, as shown in fig. 1 and fig. 18, in an embodiment, the mounting mechanism 12 further includes an elastic restoring member 700, and the elastic restoring member 700 is disposed between the sliding member 300 and the fixing member 100, for automatically restoring the sliding member 300 from the first position to the second position. Thus, the elastic reset piece 700 is arranged between the sliding piece 300 and the fixed piece 100, so that the automatic reset force directly acts on the sliding piece 300, and the automatic reset reliability of the sliding piece 300 is ensured.

One end of the elastic restoring member 700 is fixed to the stationary member 100, and the other end of the elastic restoring member 700 is directly or indirectly fixed to the slider 300.

By combining the slide bar 600, the other end of the elastic restoring member 700 is fixed on the slide bar 600, so as to fix the distance between the elastic restoring member 700 and the slider 300.
