[0039] The technology of mammography machines is developing rapidly. During the clinical use of the compression plate of a mammography machine, it needs to be frequently replaced. At the same time, the compressor design requires a safe decompression method to be able to release the pressure of the compressor manually in case of power failure or system failure. Currently in the market, the compression plate is often installed by using screws or knobs for replacement, which is complex in operation and low in usage efficiency. Moreover, the release device of the compression plate uses a button-linkage device for release, which is difficult to operate and prone to jamming.

[0040] To solve the above problems, the present utility model proposes a release device for the compression plate of a mammography machine, aiming to provide a compression plate for a mammography machine that is quick to replace, easy to operate, and not prone to jamming. Figures 1 to 4 It is a schematic structural diagram of an embodiment provided by a release device for the compression plate of a mammography machine according to the present utility model.

[0041] Please refer to Figures 1 to 3, the present utility model proposes a release device 1000 for a mammography compression plate 1, which includes a compression plate 1, a seat structure 2, a release structure 3 and a handle 4; one side of the seat structure 2 is set as an installation end face 11, and the compression plate 1 is installed on the installation end face 11; a receiving cavity 21 is provided inside the seat structure 2; the release structure 3 is received in the receiving cavity 21, and a part extends outwards from the receiving cavity 21 to the outside of the seat structure 2 to form a driving part 31; the release structure 3 has a movement stroke for pressing or loosening the compression plate 1: the handle 4 is provided with a connecting arm 41, which is connected to the driving part 31 to drive the release structure 3 to press or loosen the compression plate 1.

[0042] In the technical solution of the present utility model, the compression plate 1 is installed on the seat structure 2, the seat structure 2 is provided with a receiving cavity 21, the release structure 3 is received in the receiving cavity 21, the release structure 3 is provided with a driving part 31 extending outwards from the receiving cavity 21 to the outside of the seat structure 2, and is connected through the connecting arm 41 of the handle 4. When the handle 4 is rotated, the release structure 3 is driven to press or loosen the compression plate 1. The structure is simple, the operation is easy, and it is not easy to lock.

[0043] Further, please refer to Figure 2 , the seat structure 2 includes a first seat body 22 and a second seat body 23. The first seat body 22 is recessed with a receiving groove 221, and the second seat body 23 covers the notch of the receiving groove 221 and is installed with the first seat body 22. It can be understood that the seat structure 2 can be an integral structure or a split structure. If it is an integral structure, the processing difficulty of the receiving cavity 21 will be very high, and thus the product economic cost. Therefore, in this embodiment, the seat structure 2 is set as a split structure. Specifically, the seat structure 2 is composed of the first seat body 22 and the second seat body 23. The first seat body 22 is recessed with the receiving groove 221, and the second seat body 23 is installed with the first seat body 22 relative to the notch of the receiving groove 221, so that the receiving groove 221 forms the receiving cavity 21.

[0044] Further, please refer to Figure 2, two mounting plates 222 are protruded along the length direction of the pressing plate 1 on the first seat body 22, and are clamped and abutted against the two side walls along the length direction of the second seat body 23. It can be understood that, in order to ensure the reliability of the installation of the first seat body 22 and the second seat body 23, and further ensure the sealing degree of the accommodating cavity 21, the two mounting plates 222 are protruded along the length direction of the pressing plate 1 on the first seat body 22, and are clamped and abutted against the two side walls along the length direction of the second seat body 23; further, for easy disassembly and assembly, magnetic materials that attract each other can be provided on the two mounting plates 222 of the first seat body 22 and the side walls of the second seat body 23 that are clamped. Of course, for the reliability of installation, the first seat body 22 and the second seat body 23 are bolted together with set screws on the mounting plates 222, and the connection is more reliable.

[0045] In addition, please refer to Figure 2 , the release structure 3 includes a rotating shaft 32, which is accommodated in the accommodating cavity 21, extends along the length direction of the pressing plate 1, and at least one end extends out of the seat body structure 2 to form the driving part 31. It can be understood that, in order to enable the handle 4 to drive the release structure 3 through the driving part 31, therefore, the release structure 3 includes the rotating shaft 32, which is accommodated in the accommodating cavity 21, extends along the length direction of the pressing plate 1, and at least one end extends out of the seat body structure 2 to form the driving part 31. Further, in order to better drive the rotation of the rotating shaft 32, so that the release structure 3 has a movement stroke of pressing or loosening the pressing plate 1, both ends of the rotating shaft 32 extend from the accommodating cavity 21 to the outside of the seat body structure 2, and the handle 4 extends along the length direction of the pressing plate 1, and two connecting arms 41 are formed by bending the two ends in the same direction, respectively connecting the driving part 31, so as to better drive the release structure 3, reduce the torque of the rotating shaft 32, and protect the service life of the rotating shaft 32.

[0046] Further, please refer to Figure 2 、 Figure 5 and Figure 6, the release structure 3 further includes at least one limiting boss 33 protruding in the accommodation cavity 21 along the height direction of the pressing plate 1; the rotating shaft 32 is recessed with a mating plane 321 relative to the limiting boss 33. To enable the pressing plate 1 to have the function of being pressed by the release structure 3, specifically, the release structure 3 further includes at least one such limiting boss 33 protruding in the accommodation cavity 21 along the height direction of the pressing plate 1; the rotating shaft 32 is recessed with the mating plane 321 relative to the limiting boss 33. When the handle 4 rotates the rotating shaft 32 through the driving part 31 until the mating plane 321 abuts against the top surface of the limiting boss 33, the pressing plate 1 cannot be turned upwards at this time. At this time, the pressing plate 1 is in a pressed state; when the handle 4 rotates the rotating shaft 32 through the driving part 31 until the mating plane 321 abuts against the side wall surface of the limiting boss 33, the pressing plate 1 can be turned upwards at this time. Thus, the pressing plate 1 is in a released state.

[0047] Further, please refer to Figure 2 , Figure 5 and Figure 6 , the release device 1000 of the breast machine pressing plate 1 further includes a fixing structure 5 for fixing when the release structure 3 presses the pressing plate 1, including a convex column 51 and a ball groove 52, one of which is arranged on the rotating shaft 32 and the other is arranged at the bottom of the accommodation groove 221. It can be understood that when the handle 4 rotates the rotating shaft 32 through the driving part 31 until the mating plane 321 abuts against the top surface of the limiting boss 33, the pressing plate 1 cannot be turned upwards at this time. At this time, the pressing plate 1 is in a pressed state; however, if the operator releases the handle 4 once, the release structure 3 loses the pressing effect on the pressing plate 1, which is very inconvenient during use. Thus, the release device 1000 of the breast machine pressing plate 1 further includes the fixing structure 5 for fixing when the release structure 3 presses the pressing plate 1. The fixing structure 5 includes the convex column 51 and the ball groove 52, one of which is arranged on the rotating shaft 32 and the other is arranged at the bottom of the accommodation groove 221. When the mating plane 321 of the rotating shaft 32 abuts against the top surface of the limiting boss 33, the free end of the convex column 51 is embedded in the ball groove 52, so as to press the pressing plate 1 by the release structure 3. Thus, the pressing plate 1 cannot rotate and further enters a locked state.

[0048] Further, the convex post 51 and the ball groove 52 are set as a fixing group, and a plurality of the fixing groups are provided and arranged at intervals. When the pressing plate 1 is in the locked state, the free end of the convex post 51 is embedded in the ball groove 52, so that the pressing plate 1 cannot be turned towards the handle 4. In order to better limit the turning of the pressing plate 1 and keep it in the locked state, the convex post 51 and the ball groove 52 are set as a fixing group, and a plurality of the fixing groups are provided and arranged at intervals. Through the limitation of multiple fixing groups, it is more difficult for the pressing plate 1 to turn, and the locked state is better.

[0049] In addition, please refer to Figure 2 , the releasing device 1000 of the breast machine pressing plate 1 further includes an installation structure 6, and the installation structure 6 includes at least one installation post 61; a through hole 11 penetrates through a side wall of the pressing plate 1 opposite to the installation end face 11, and a first groove 24 is recessed in the installation end face 11 opposite to the through hole 11; the installation post 61 penetrates from the through hole 11 into the first groove 24, with a part of it accommodated in the through hole 11 and another part accommodated in the first groove 24. It can be understood that, in order to install the pressing plate 1 on the installation end face 11, in some embodiments, bolt installation can be used. However, in many cases, the pressing plate 1 needs to be disassembled and replaced according to the usage requirements, and the bolt installation method is not conducive to loading and unloading. Therefore, in another embodiment, specifically, the releasing device 1000 of the breast machine pressing plate 1 further includes the installation structure 6, and the installation structure 6 includes at least one installation post 61; a through hole 11 penetrates through a side wall of the pressing plate 1 opposite to the installation end face 11, and a first groove 24 is recessed in the installation end face 11 opposite to the through hole 11; the installation post 61 penetrates from the through hole 11 into the first groove 24, with a part of it accommodated in the through hole 11 and another part accommodated in the first groove 24. By adopting such an installation method to install the pressing plate 1 on the installation end face 11, when disassembly is required, only the installation post 61 needs to be inserted through the through hole 11 into the position of the first groove 24 on the installation end face 11, so that the pressing plate 1 is connected to the seat structure 2.

[0050] Further, please refer to Figure 2, the compression plate 1 release device 1000 of the mammography machine further includes a limiting structure 7, and the limiting structure 7 includes a ball plunger 71: a circumferential annular groove 611 is recessed on the circumference of the part of the mounting post 61 accommodated in the first groove 24; on the side wall of the seat body structure 2 along the length direction of the compression plate 1, a second groove 25 is recessed opposite to the first groove 24, the ball plunger 71 is accommodated in the second groove, and the end is embedded in the annular groove 611. It can be understood that the compression plate 1 is mounted on the mounting end face 11 by using the mounting post 61. However, the compression plate 1 has a tendency to move out of the mounting post 61 in the width direction thereof. Therefore, the compression plate 1 release device 1000 of the mammography machine further includes a limiting structure 7 for restricting the mounting post 61 from moving out of the through hole 11 of the compression plate 1 and the first groove 24 of the seat body structure 2; in this embodiment, a circumferential annular groove 611 is recessed on the circumference of the part of the mounting post 61 accommodated in the first groove 24, and a second groove 25 is recessed on the side wall end face of the seat body structure 2 opposite to the first groove 24 on the mounting end face 11, and the second groove 25 communicates with the first groove 24; the limiting structure 7 includes the ball plunger 71, and the ball plunger 71 is inserted into the first groove 24 through the second groove 25, so that the ball plunger 71 is inserted into the annular groove 611 of the mounting post 61, thereby restricting the compression plate 1 from moving out of the mounting end face 11 in the width direction thereof.

[0051] In addition, please refer to Figure 2 and Figure 4 , it further includes a guiding structure 8, which is arranged between the mounting end face 11 and the compression plate 1; the guiding structure 8 includes a guiding boss 81 and a guiding groove 82, and one of them is arranged on the mounting end face 11 and the other is arranged on the compression plate 1. It can be understood that in order to mount the compression plate 1 on the mounting end face 11 in a relatively unique posture, the compression plate 1 release device 1000 of the mammography machine further includes the guiding structure 8, which is arranged between the mounting end face 11 and the compression plate 1; the guiding structure 8 includes the guiding boss 81 and the guiding groove 82, and one of them is arranged on the mounting end face 11 and the other is arranged on the compression plate 1. Through the process of inserting the guiding boss 81 into the guiding groove 82, the compression plate 1 is mounted on the mounting end face 11 in a relatively unique posture; in this embodiment, the guiding groove 82 is arranged on the mounting end face 11, and most of the guiding bosses 81 are arranged on the compression plate 1.

[0052] The above are only the preferred embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
