DETAILED DESCRIPTION

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a centered element at the same time. When an element is considered to be "coupled" to another element, it may be directly coupled to the other element or there may be a centered element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method. The terms "distal end" and "proximal end" used herein are directional terms, which are commonly used terms in the field of interventional medical devices, wherein the "distal end" refers to the end away from the operator during surgery, and the "proximal end" refers to the end close to the operator during surgery.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] Combination Figures 1 to 3As shown, a mounting structure of a poke card according to a preferred embodiment of the present invention is schematically shown, which comprises a connecting arm 1, a mounting seat 2 and a locking mechanism 3 arranged on the mounting seat 2; wherein, the connecting arm 1 is generally arranged on the side wall of the poke card, for example, the connecting arm 1 can be arranged on the side wall of the lower shell of the sealing assembly of the poke card 100, the mounting seat 2 is generally connected to the operating arm of the robot, and a base 20 is provided at the bottom of the mounting seat 2, through which a detachable connection or a permanent connection with the operating arm can be achieved, for example, a plurality of bolt holes 201 are provided on the base 20, and a detachable connection with the operating arm is achieved by bolts, or a permanent connection is achieved by welding the base 20 to the operating arm.

[0034] The locking mechanism 3 includes a driving disk 31 and a locking tongue 32. The lower end surface of the driving disk 31 is provided with a spiral groove 311, and the spiral groove 311 expands from the center of the driving disk 31 to the periphery. A connecting column 321 is provided on the locking tongue 32, and a card slot 11 is provided on the connecting arm 1. During assembly, the connecting column 321 is inserted into the spiral groove 311, and the spiral groove 311 can convert the rotational motion of the driving disk 31 into the linear motion of the locking tongue 32. If the driving disk 31 is rotated forward so that the locking tongue 32 is stuck in the card slot 11, the connecting arm 1 can be locked. If the driving disk 31 is rotated reversely so that the locking tongue 32 is disengaged from the card slot 11, the connecting arm 1 can be released.

[0035] For example, two locking tongues 32 can be provided, and a connecting column 321 is provided on each of the two locking tongues 32. The locking tongues 32 are respectively arranged on the left and right sides of the axis of the driving disk 31. The connecting arm 1 has a card slot 11 on both opposite sides. During assembly, the connecting column 321 is inserted into the spiral groove 311, so that the space between the two locking tongues 32 forms a card slot 4.

[0036] When installing the poking card 100, it is only necessary to extend the connecting arm 1 into the bayonet 4, and then rotate the driving disk 31 forward, and the spiral groove 311 of the driving disk 31 will move the connecting column 321, so that the two locking tongues 32 are close to each other, and the opposite end faces of the two locking tongues 32 are respectively inserted into the slots 11 on the two side walls of the connecting arm 1, so that the connecting arm 1 is locked, thereby realizing the rapid positioning and installation of the poking card 100. When removing the poking card 100, it is only necessary to rotate the driving disk 31 in the opposite direction, and the spiral groove 311 of the driving disk 31 will move the connecting column 321, so that the two locking tongues 32 are separated from each other and withdrawn from the slots 11 on the two side walls of the connecting arm 1, and the poking card 100 can be quickly removed from the mounting seat 2; the whole operation is convenient and fast, and the working efficiency of the operation is improved.

[0037] Of course, the two locking tongues 32 do not have to be relatively arranged on the left and right sides of the axis of the driving disk 31. In this case, the two locking tongues 32 have a certain angle (acute angle or obtuse angle) between each other, and the corresponding slots 11 on the side wall of the connecting arm 1 can also be arranged to have a certain angle (acute angle or obtuse angle) between each other to match the positions of the two locking tongues 32; in addition, the number of locking tongues 32 and slots 11 can also be set to one; the arrangement of the locking tongues 32 and slots 11 in these two examples may also require the support and constraint of other structures (such as the inner wall of the mounting cavity 21 of the mounting seat 2) when locking the connecting arm 1 to achieve the purpose of locking the connecting arm 1.

[0038] like Figure 2 As shown, the spiral groove 311 is configured as an Archimedean spiral groove. The advantage of the Archimedean spiral groove is that the travel of the two locking tongues 32 moving synchronously can be kept consistent, so that the bayonet 4 will not shift, thereby ensuring the accuracy of the locking position of the bayonet 4.

[0039] In order to facilitate manual operation to rotate the drive disk 31, the locking mechanism 3 also includes a knob 33, which is fixedly connected to the drive disk 31 via a rotating shaft 5. The drive disk 31 can be rotated relatively easily by rotating the knob 33, so as to control the opening and closing size of the bayonet 4.

[0040] like Figure 1 and Figure 3 As shown, the mounting seat 2 is provided with a mounting cavity 21, the drive disk 31 and the lock tongue 32 are both arranged in the mounting cavity 21, the knob 33 is arranged outside the mounting cavity 21, and an opening 23 is arranged at the bottom of the mounting cavity 21 (the specific arrangement of the opening 23 can be referred to Figure 6 ), a top wall 24 is provided on the top of the installation cavity 21, the bayonet 4 is located directly above the opening 23, the connecting arm 1 can be extended into the bayonet 4 or withdrawn from the bayonet 4 through the opening 23, a shaft hole 25 is provided on the top wall 24, a knob 33 is arranged on the outer side of the top wall 24, and a shaft 5 passes through the shaft hole 25 to fix the driving disk 31 and the knob 33. Such a design layout is more in line with the operator's operating posture, and improves the convenience of assembly and disassembly of the stamping card 100.

[0041] A guide groove 22 is provided in the installation cavity 21 to guide the movement of the lock tongue 32 so that the lock tongue 32 can always move in a straight line, thereby preventing the lock tongue 32 from swinging during the movement and causing jamming, and making the lock tongue 32 move more smoothly.

[0042] Specifically, please combine Figure 1 , Figure 4 and Figure 5As shown, a lock tongue mounting plate 6 is provided in the mounting cavity 21, and the lock tongue mounting plate 6 is located below the driving disk 31. The guide groove 22 is provided on the lock tongue mounting plate 6. The lock tongue 32 includes a guide portion 322, a connecting portion 323 and a locking claw 322. The connecting portion 323 is connected between the guide portion 322 and the locking claw 324. The guide portion 322 and the connecting portion 323 roughly form a "7" shape. The locking claw 324 is provided at the end of the connecting portion 323 to leave a clamping space for clamping the locking connecting arm 1. The guide portion 322 can be perpendicular to the connecting portion 323, and the two can also form an acute angle. The connecting column 321 is provided on the upper end surface of the guide portion 322, and the guide portion 322 is slidably fitted in the guide groove 22.

[0043] Please combine Figure 1 , Figure 4 and Figure 6 As shown, a rear cover 7 is provided at the bottom of the mounting cavity 21, and a receiving cavity 71 is provided in the rear cover 7. An avoidance hole 61 is also provided on the locking tongue mounting plate 6. The connecting portion 323 passes through the avoidance hole 61. The connecting portion 323 and the locking claw 324 of the locking tongue 32 are arranged in the receiving cavity 71, and the opening 23 is arranged at the bottom of the receiving cavity 71. Such an arrangement can improve the compactness of the structure.

[0044] like Figure 7 As shown, the cross-sectional shape of the card slot 11 is a "V" shape. When the locking tongue 32 is inserted into the card slot 11, the connecting arm 1 is locked tighter under the guidance of the inner wall of the card slot 11, thereby avoiding the possibility of shaking of the poking card 10 after the installation is completed due to the gap between the card slot 11 and the locking tongue 32 after the locking tongue 32 is inserted into the card slot 11.

[0045] More preferably, the "V"-shaped slot 11 is composed of an inclined wall 11a and a horizontal wall 11b. There are two ways of splicing here. One is that the inclined wall 11a is placed on the top and the horizontal wall 11b is placed on the bottom. The advantage of this splicing method is that when the lock tongue 32 is inserted into the slot 11, the guiding effect of the inclined wall 11a causes the connecting arm 1 to move into the installation cavity 21, so that the top wall of the connecting arm 1 is close to the lower end surface of the driving disk 31, and the horizontal wall 11a is close to the lock tongue 32, thereby holding the connecting arm 1 tighter, further improving the stability of the installation of the poking card 100; the other is that the inclined wall 11a is placed on the bottom and the horizontal wall 11b is placed on the top. The advantage of this splicing is that when the guiding effect of the inclined wall 11a makes the horizontal wall 11b close to the upper end surface of the lock tongue 32, it will make the connecting arm 1 more difficult to be pulled out of the bayonet 4.

[0046] like Figure 1As shown, in one of the embodiments, the mounting structure of the poking card further includes a locking mechanism 8. The purpose of providing the locking mechanism 8 is to prevent the locking mechanism 3 from being loosened during the operation of the poking card 100 after being locked in place; the locking mechanism 8 includes a locking groove 81, a locking member 82 and an elastic member 83. The elastic member 83 presses the locking member 82 into the locking groove 81 to lock the knob 33. Since the knob 33 is fixedly connected to the driving disk 31 through the rotating shaft 5, locking the knob 33 is equivalent to locking the driving disk 31, thereby effectively solving the problem of the poking card 100 being loosened after being locked. Moreover, since the knob 33 is an exposed member, the design difficulty of the locking mechanism 8 can be reduced, and the structure of the locking mechanism 8 is simplified.

[0047] Specifically, the locking member 82 and the elastic member 83 are both arranged in a mounting groove 84, and the locking member 82 includes a toggle portion 82a and an abutment portion 82b, wherein the toggle portion 82a extends from the upper end of the mounting groove 84, so that the toggle portion 82a can be manually operated to retract the locking member 82 from the locking groove 81 to unlock the knob 33, and the abutment portion extends from the front end of the mounting groove 84, and is inserted into the locking groove under the action of the elastic member 83 to lock the knob.

[0048] For example, the mounting groove 84 can be set on the knob 33, and a snap-fit ​​seat 85 can be set at a position on one side of the mounting seat 2 close to the knob 33, and the locking groove 81 can be set on the snap-fit ​​seat 85. This setting method can realize unlocking or locking the knob 33 with one hand operation.

[0049] For another example, the locking groove 81 can be set on the side wall of the knob 33, and a support seat (not shown) is provided at a position on the side of the mounting seat close to the knob 33, and the mounting groove 84 is provided on the support seat. This arrangement can set multiple locking grooves 81 in the circumferential direction of the knob 33, so as to realize continuous adjustment of the tightness of the locking mechanism 3 locking the stamp 100.

[0050] In addition, if Figure 8 As shown, a first mark 9a can be set on the knob 33, and a second mark 9b can be set on the side of the mounting base 2 close to the knob 33. When the knob 33 is turned to align the first mark 9a with the second mark 9b, it indicates that the locking mechanism 3 is locked in place, thereby improving the accuracy of the operator locking the stamp card 100.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
