DETAILED DESCRIPTION

[0030] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0031] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0032] The embodiment of the utility model provides a probe matching box. The probe matching box can be used in a variety of fields, including but not limited to medical, industrial, etc. The probe matching box provided by the utility model can be used in ultrasonic diagnostic equipment. The following will be combined with the accompanying drawings to introduce a probe matching box according to an embodiment of the utility model in detail.

[0033] Combined with reference Figures 1 to 5 The sealing device 100 of the probe matching box of the utility model may include a housing 110 and a fastening assembly 120. The housing 110 may form a receiving cavity 130 and may cover the electrical connection end of the outer shell of the probe matching box 200 along a first direction A. The fastening assembly 120 may be arranged on the outer side of the bottom wall of the housing 110 opposite to the first direction A. It can be understood that the first direction A may be the direction in which the housing 110 covers the electrical connection end of the outer shell of the probe matching box 200. Figure 5 The fastening assembly 120 is disposed on the outer side of the bottom wall of the housing 110, and can better provide the squeezing force along the first direction A when the housing 110 is covered on the probe matching box 200 and sealed, so that the sealing effect is more reliable.

[0034] In order to make it easy for the shell 110 to cover the electrical connection end of the outer shell of the probe matching box 200, the shape of the shell 110 can be similar to the shape of the outer shell of the probe matching box 200, and the shell 110 can be generally square box-shaped. Of course, the shell 110 can also be in other shapes. When the fastening assembly 120 is in a fastened state, the shell 110 can squeeze the electrical connection end of the outer shell of the probe matching box 200 along the first direction A, so that the accommodating cavity 130 is in a sealed state. Generally speaking, the outermost edge of the outer shell of the probe matching box 200 in the prior art is smooth and falls on the same plane. At this time, as long as the surface of the shell 110 abutting against it during squeezing is also a plane, the two can be squeezed to achieve a sealing effect; of course, in special circumstances, if the outermost edge of the electrical connection end of the outer shell of the probe matching box 200 is other shapes, as long as the surface of the shell 110 abutting against it during squeezing is set to a shape that matches the former, the two can also be squeezed to achieve a sealing effect. Therefore, the shape of the abutting surface of the two is not limited here, as long as the matching shape that can be squeezed to form a sealing effect is within the protection scope of the utility model.

[0035] In the sealing device 100 of the probe matching box of the utility model, when the fastening assembly 120 is in a fastened state, the housing 110 can press the electrical connection end of the housing of the probe matching box 200 along the first direction A, so that the accommodating cavity 130 is in a sealed state. When applied to the probe matching box 200, the sealing performance of the probe matching box 200 can be improved, so that the probe matching box 200 can be waterproof, so that the probe matching box 200 can be immersed and disinfected after use, avoiding the risk of cross contamination. There can be two fastening assemblies 120, which are respectively located at the left and right ends of the housing 110.

[0036] In one embodiment of the present utility model, Figure 4 and Figure 5, the fastening assembly 120 may include a mounting member 123, a first fastening member 121, and a second fastening member 122. The mounting member 123 may be fixed to the bottom wall of the housing 110, the first fastening member 121 may be rotatably connected to the mounting member 123, and the second fastening member 122 may be rotatably connected to the first fastening member 121 and may be combined with or separated from the probe matching box 200. When the first fastening member 121 rotates, the second fastening member 122 may be driven to move, and the movement direction generated by the second fastening member 122 may include a component parallel to the first direction A, so that the fastening assembly 120 may enter or release the fastening state. The mounting member 123 may be connected to the outer side of the bottom wall of the housing 110 by screws, and the mounting member 123 may also be connected to the outer side of the bottom wall of the housing 110 by other connection methods, such as adhesive connection, rivet connection, or welding, etc. With such arrangement, on the one hand, the mounting member 123 is placed in the external space, thus saving space for the accommodating cavity 130; on the other hand, the first fastener 121 can be directly rotatably connected to the mounting member 123 without the need for connection with other parts, such as sheet metal parts, metal plates, etc., thus saving manufacturing costs.

[0037] In one embodiment of the present utility model, in conjunction with reference to Figure 1 and Figure 4 When the fastening assembly 120 is in the fastened state, the first fastener 121 is at least partially in contact with the outer side of the bottom wall of the housing 110, so that the outer dimensions of the entire sealing device 100 are smaller when in the working state (sealed connection or storage), saving the volume of the product outer packaging. With such a configuration, when the fastening assembly 120 is adjusted to the fastened state, the outer side of the bottom wall of the housing 110 limits the first fastener 121, and the adjustment of the first fastener 121 can be completed.

[0038] In one embodiment of the present utility model, in conjunction with reference to Figure 3 , Figure 4 and Figure 7, the first fastener 121 may include a main body 1211 and an extension 1212. The first fastener 121 may be a gusset plate, the main body 1211 may be the plate body portion of the gusset plate, and the extension 1212 may be the hand-held portion of the gusset plate. The main body 1211 may be rotatably connected to the mounting member 123 via a hinge shaft, for example, the main body 1211 may have a first through hole 1211a, and the pin 124 may pass through the first through hole 1211a to connect the main body 1211 to the mounting member 123, so that the entire first fastener 121 may rotate around the pin 124. In order to enhance the firmness of the connection between the main body 1211 and the mounting member 123, the main body 1211 may have two first through holes 1211a, and the two first through holes 1211a are respectively located at both ends of the main body 1211. The main body 1211 may also have a second through hole 1211b at a position away from the mounting piece 123. There may also be two second through holes 1211b, which may also be located at both ends of the main body 1211 respectively. The second fastener 122 may be a lock buckle that is generally in the shape of a square ring. The shape of the second fastener 122 is related to the shape of the probe matching box 200. The two ends of the lock buckle may respectively pass through the second through holes 1211b at both ends. The passed parts may be flattened to prevent the lock buckle from detaching from the main body 1211. Of course, the passed parts may also be connected with a nut or a tight-fitting part to ensure that the lock buckle is stably connected to the main body 1211. The extension part 1212 may extend from the edge of the main body 1211 and may have at least one bent extension section. When the fastening assembly 120 is in a fastened state, there may be a gap between the bent extension section and the outer side of the bottom wall of the housing 110, so that the user can insert a finger into the gap and hold the extension part 1212 to rotate, thereby driving the main body 1211 to rotate, and then driving the entire first fastener 121 to rotate, and the user can put his hand in the gap and rotate the bent extension section to release the fastening state. With this arrangement, the fastening assembly 120 has a simple structure and is easy to operate.

[0039] In one embodiment of the present invention, the extension portion 1212 may have one or more extension segments. The extension portion 1212 may have an extension segment 1212a, a first bending extension segment 1212b, and a second bending extension segment 1212c. Figure 4 and Figure 5When the fastening assembly 120 is in a fastened state, the extension section 1212a can extend from the edge of the main body 1211 along the second direction, and the second direction is perpendicular to the first direction A. It should be understood that when the first direction A is a vertical direction, the second direction is a horizontal direction. The first bent extension section 1212b can be bent and extended from one end of the extension section 1212a away from the main body 1211, and the end of the first bent extension section 1212b away from the extension section 1212a can be higher than the end connected to the extension section 1212a. The second bent extension section 1212c can be bent and extended from one end of the first bent extension section 1212b away from the extension section 1212a, and the end of the second bent extension section 1212c away from the first bent extension section 1212b can be lower than the end connected to the first bent extension section 1212b. Such a configuration makes it convenient for the user to hold the extension portion 1212 , and when the extension portion 1212 is parallel to the bottom wall of the shell 110 , it avoids the phenomenon that the extension portion 1212 is completely attached to the outer side of the bottom wall of the shell 110 and is inconvenient to grasp.

[0040] In one embodiment of the present invention, refer to Figure 3 The bent extension section may be covered with a protective cover 1213. The protective cover 1213 may be a hose, and the protective cover 1213 may be made of rubber or silicone material, etc. Such a configuration not only prevents the extension 1212 from scratching the bottom wall of the housing 110, but also prevents the user's hand from being scratched when the user holds the extension 1212 and rotates it.

[0041] In one embodiment of the present invention, when the protective cover 1213 is sleeved on the extension portion 1212, it can be elastically deformed according to the shape of the extension portion 1212 after being bent and extended. Of course, the protective cover 1213 can also be manufactured according to the shape of the extension portion 1212 after being bent and extended. Figure 3 and Figure 4 The protective cover 1213 may include a first cover section 1213a and a second cover section 1213b. The second cover section 1213b may be bent and extended from one end of the first cover section 1213a. The first cover section 1213a may be sleeved on the first bent extension section 1212b, and the second cover section 1213b may be sleeved on the second bent extension section 1212c. With such a configuration, the protective cover 1213 may be sleeved on the bent and extended portion of the extension portion 1212, and is not easy to fall off, thereby preventing the bent and extended portion from scratching the outer side of the bottom wall of the housing 110 and preventing the user from being scratched.

[0042] In one embodiment of the present invention, again in conjunction with reference to Figure 3 and Figure 4When the fastening assembly 120 is in a fastened state, the end of the second sleeve section 1213b away from the first sleeve section 1213a and the extension section 1212a can be in the same plane. In this way, the second sleeve section 1213b covers the entire second bent extension section 1212c, preventing the user from being scratched by touching the second bent extension section 1212c when rotating the extension section 1212. Of course, it is not excluded that the end of the first sleeve section 1213a away from the second sleeve section 1213b and the extension section 1212a can be in different planes.

[0043] In one embodiment of the present invention, refer to Figure 5 , a leak detection valve 140 may be further provided on the housing 110. The leak detection valve 140 may have a first state and a second state. When the leak detection valve 140 is in the first state, the accommodating chamber 130 may be connected to the outside; when the leak detection valve 140 is in the second state, the accommodating chamber 130 may not be connected to the outside. Figure 4 , a mounting hole 112 may be provided on the side wall of the housing 110, and a mounting step 1121 may extend from the edge of the mounting hole 112. The leak detection valve 140 may pass through the mounting hole 112 and be fixed on the mounting step 1121, and the passing portion may be connected to the fastener 146. The mounting hole 112 may also be provided on the outer housing 210. With such a configuration, a leak detection may be performed before the probe matching box 200 is cleaned and disinfected to ensure that the sealing of the probe matching box 200 is intact, and to prevent the disinfectant from flowing into the accommodating chamber 130 and damaging the device when the probe matching box 200 is immersed in the disinfectant. Figure 5 and Figure 6 When leak testing the probe matching box 200, a leak detector 400 is required. The leak detector 400 is connected to the leak detection valve 140. At this time, the leak detection valve 140 is in the first state. The leak detector 400 is squeezed to input air into the accommodating chamber 130 to increase the air pressure in the accommodating chamber 130. When the air pressure in the accommodating chamber 130 reaches a certain air pressure value, the entire probe matching box 200 and part of the leak detector 400 are immersed in liquid to observe whether bubbles are generated in the liquid, thereby judging whether the probe matching box 200 is leaking.

[0044] In one embodiment of the present utility model, in conjunction with reference to Figure 5 , Figure 6 and Figure 8, the leak detection valve 140 may include a valve body 141, a valve core 142 and a rotation limiting structure 143. A communication port 1411 may be provided on the valve body 141. The valve core 142 may be rotatably arranged in the valve body 141 through the rotation limiting structure 143. The rotation limiting structure 143 may open or close the communication port 1411 by driving the valve core 142 to move axially during the rotation of the valve core 142 relative to the valve body 141. The valve body 141 may also be provided with a first channel 1412. When the communication port 1411 is opened, the leak detector 400 may input air into the accommodating chamber 130 through the first channel 1412; when the communication port 1411 is closed, the first channel 1412 and the accommodating chamber 130 form a closed space. In this way, the structure of the leak detection valve 140 is simple, and the manufacturing cost is saved. Moreover, through the arrangement of the valve body 141, the valve core 142 and the rotation limiting structure 143, the leak detection valve 140 can be switched between the first state and the second state. A second sealing member 144 may be provided between the valve core 142 and the valve body 141 to enhance the sealing performance of the leak detection valve 140 , thereby enhancing the accuracy of leak detection.

[0045] In one embodiment of the present utility model, in conjunction with reference to Figure 8 and Fig. 9 The rotation limiting structure 143 may include a limiting groove 1431 provided on the valve body 141, and a matching piece 1432 provided on the valve core 142. The matching piece 1432 may have a sliding connection portion 1432a slidably provided in the limiting groove 1431. The limiting groove 1431 may have a first end 1431a and a second end 1431b, and the sliding connection portion 1432a is limited to move between the first end 1431a and the second end 1431b. When the sliding connection portion 1432a is located at the first end 1431a, the leak detection valve 140 is in a first state, and when the sliding connection portion 1432a is located at the second end 1431b, the leak detection valve 140 is in a second state. The matching piece 1432 may be a pin fixed on the valve core 142, or the matching piece 1432 may be formed by protruding from the valve core 142. With such arrangement, the rotation limiting structure 143 has a simple structure, which simplifies the manufacturing process, and the leakage detection function of the leakage detection valve 140 can be realized through a simple structure.

[0046] In one embodiment of the present invention, again in conjunction with reference to Figure 5 , Figure 6 and Figure 8The leak detection valve 140 may include a valve housing 145 sleeved outside the valve body 141, and a limit pin 1451 may protrude from the valve housing 145. The limit pin 1451 and the valve housing 145 may be an integrated structure, the limit pin 1451 and the valve housing 145 may be a split structure, and the limit pin 1451 may be a pin. When the leak detection valve 140 is connected to the leak detector 400, the leak detector 400 may be limited and fixed by the limit pin 1451. The valve housing 145 and the valve body 141 may be fixedly connected by a plurality of screws, and the valve housing 145 and the valve body 141 may also be connected by other connection methods, such as snap connection or welding, etc. In order to enhance the sealing performance of the leak detection valve 140, a third sealing member 148 may also be provided between the valve housing 145 and the valve body 141. The valve housing 145 may have a second channel 1452 in communication with the first channel 1412, and the first channel 1412 may be connected to the accommodating chamber 130 through the second channel 1452. The valve housing 145 may pass through the mounting hole 112, and the valve housing 145 also has a clamping portion 1453 that can clamp the mounting step 1121. The portion of the valve housing 145 that passes through the mounting hole 112 may be tightly fitted with the fastener 146, and the outer wall of the portion of the valve housing 145 that passes through the mounting hole 112 may also have an external thread structure, the fastener 146 may be a nut, and the valve housing 145 may be connected to the nut through the external thread structure. Such a configuration simplifies the manufacturing process and facilitates production and processing. Of course, it is not ruled out that the valve housing 145 and the valve body 141 may be an integrated structure.

[0047] In one embodiment of the present utility model, in conjunction with reference to Figure 6 , Figure 8 and Fig. 9 A connecting sleeve 147 may be provided between the valve body 141 and the valve housing 145. The connecting sleeve 147 may have an extended section 1471 extending from the end of the valve housing 145. A snap-fit ​​groove 1471a may be provided on the extended section 1471. A fourth sealing member 149 may be provided between the connecting sleeve 147 and the valve body 141 to further enhance the sealing performance of the leak detection valve 140. A fixing nail may be provided on the leak detector 400. When the leak detector 400 is connected to the leak detection valve 140, the fixing nail and the snap-fit ​​groove 1471a may be snap-fitted. The fixing nail and the leak detector 400 may be an integrated structure, or the fixing nail and the leak detector 400 may be a split structure, and the fixing nail may be a pin. With such arrangement, the leak detector 400 is connected to the leak detection valve 140, and the connecting sleeve 147 can drive the sliding connection part 1432a to move between the first end 1431a and the second end 1431b of the limiting groove 1431, so that a leak detection operation can be performed, and the leak detection operation is simple.

[0048] Combined with reference Figure 1 and Figure 3According to another aspect of the present invention, a probe matching box 200 is provided, which can be used to match the sealing device 100 of the probe matching box as described above. The probe matching box 200 can have an outer shell 210. The outer shell 210 can have a matching portion 212 on the top wall opposite to the aforementioned electrical connection end. When the fastening assembly 120 is in a fastened state, the fastening assembly 120 can match with the matching portion 212 to make the connection between the two more reliable and tight.

[0049] The outer shell 210 may also have a cable connection terminal 220 connected to the cable. The top wall of the outer shell 210 may also be provided with a knob switch 230. When the knob switch 230 is turned on, the probe matching box 200 can transmit information, and when the knob switch 230 is turned off, the probe matching box 200 can disconnect the information transmission.

[0050] In another embodiment of the present invention, Figure 3 and Figure 5 , the matching portion 212 may include a protrusion 2121 protruding toward the first direction A and a slot 2122 recessed in a direction opposite to the first direction A. When the fastening assembly 120 is in a fastened state, the second fastener 122 may be clamped in the slot 2122, and the protrusion 2121 is located beside the slot 2122 to prevent the second fastener 122 from coming out of the slot 2122. In this way, the second fastener 122 is restricted by the protrusion 2121 and the slot 2122, thereby preventing the second fastener 122 from accidentally coming out of the matching portion 212 when the fastening assembly 120 is in a fastened state. In an embodiment not shown, the matching portion 212 may be a protrusion 2121 protruding toward the first direction A. When the fastening assembly 120 is in a fastened state, the second fastener 122 is restricted by the protrusion 2121, thereby preventing the second fastener 122 from accidentally coming out of the matching portion 212. In an embodiment not shown, the matching portion 212 may be a slot 2122 recessed in a direction opposite to the first direction A, and the second fastener 122 may be locked in the slot 2122, so that the second fastener 122 may be prevented from accidentally disengaging from the matching portion 212 when the fastening assembly 120 is in a fastened state. It is understandable that when the user is ready to adjust the fastening assembly 120 to a fastened state, the second fastener 122 needs to be rotated to a position higher than the protrusion 2121.

[0051] See also Figure 1According to another aspect of the utility model, an ultrasonic diagnostic device is provided, which may include the sealing device 100 of the probe matching box and the probe matching box 200 as described above. The ultrasonic diagnostic device of the utility model includes the sealing device 100 of the probe matching box and the probe matching box 200 as described above. Since the sealing device 100 of the probe matching box and the probe matching box 200 have the beneficial effects as described above, the ultrasonic diagnostic device including the sealing device 100 of the probe matching box and the probe matching box 200 must also have the beneficial effects as described above.

[0052] In another embodiment of the present invention, refer again to Figure 5 , the housing 110 can be connected to the outer housing 210 along the first direction A. The housing 110 can have a first connection end face 111 close to the outer housing 210, and the outer housing 210 can have a second connection end face 211 close to the housing 110, and a first sealing member 300 can be arranged between the first connection end face 111 and the second connection end face 211. When the fastening assembly 120 is in a fastened state, the first sealing member 300 can be squeezed by the outer housing 210 and / or the housing 110, so that the first sealing member 300 is subjected to a force perpendicular to the first connection end face 111 and / or the second connection end face 211 and is in a compressed state. The first connection end face 111 can at least partially form a connection portion 1111 in the first direction A, and when the housing 110 is covered on the outer housing 210, the connection portion 1111 can be close to the outer wall of the outer housing 210, thereby enhancing the stability and sealing of the connection between the outer housing 210 and the housing 110. In order to make the first sealing member 300 better fit with the first connection end face 111 and the second connection end face 211 and produce a better sealing effect, the first sealing member 300 can be a square ring-shaped sealing ring, and of course the first sealing member 300 can also be a circular ring-shaped sealing ring, etc. The first sealing member 300 can be made of rubber material or silicone material, etc. It should be understood that the first sealing member 300 is not necessary, and the first sealing member 300 can also be omitted if the sealing requirements can be met after the housing 110 and the outer housing 210 are connected.

[0053] In another embodiment of the present invention, refer again to Figure 5, the first connection end surface 111 is provided with a mounting groove 1112 in a direction opposite to the first direction A, and the first sealing member 300 is placed in the mounting groove 1112. In an embodiment not shown, the second connection end surface 211 may be provided with a mounting groove in the first direction A, and the first sealing member 300 is placed in the mounting groove. With such a configuration, when the first sealing member 300 is in a compressed state by a force perpendicular to the first connection end surface 111 and / or the second connection end surface 211, it is simultaneously fixed by the two side walls of the mounting groove 1112, thereby preventing the first sealing member 300 from being separated from the first connection end surface 111 and the second connection end surface 211 when in a compressed state.

[0054] Specifically, the fastening assembly 120 is adjusted to a fastened state. First, the shell 110 needs to be covered on the outer shell 210, and the connecting portion 1111 is pressed against the outer wall of the outer shell 210, so that the shell 110 limits the outer shell 210. When limiting, the second fastener 122 can be directly rotated, or the second fastener 122 can be driven by rotating the first fastener 121 to ensure that the second fastener 122 is higher than or equal to the top wall of the outer shell 210. Then, the first fastener 121 is rotated until the first fastener 121 at least partially fits with the outer side of the bottom wall of the shell 110, and the first fastener 121 hugs the shell 110. At this time, the second fastener 122 is pulled downward by the first fastener 121 and hugs the outer shell 210. The outer shell 210 and / or the shell 110 squeeze the first seal 300, so that the first seal 300 is compressed by a force perpendicular to the first connection end face 111 and / or the second connection end face 211.
