[0005] 2. The more times the bolts are disassembled, the more likely it is that the bolts will break or be decoupled, resulting in the fixed object falling off;

[0006] 3. The machining precision of the bolt holes on the object, the bolt holes on the supporting frame, and the gaskets and other accessories needs to be high to ensure that the bolts are not over-tightened or not tightened enough when tightened.

[0007] 4.

[0057] In the prior art, the support frame is generally fixed and installed with medical equipment by using fastening screws, but there are many defects, which is not conducive to the installation of medical equipment. In view of this, one embodiment of the present application discloses a connecting mechanism, comprising: a connecting seat 100, the connecting seat 100 is provided with a containing groove 101 for installing a medical equipment Q, one side of the containing groove 101 is provided with an insertion groove 102 communicated with the containing groove 101; a driving clamping part is arranged on one side of the connecting seat 100 corresponding to the insertion groove 102, the clamping segment of the driving clamping part can enter or withdraw from the containing groove 101 through the insertion groove 102, and is combined or separated with the medical equipment Q; one end of the driving clamping part is connected with the switch handle 400 capable of locking or separating the medical equipment Q. Thus, any part of the medical equipment that needs to be fixed can be placed in the containing groove, the driving clamping part is driven to rotate by the switch handle, and then the clamping segment of the driving clamping part is locked or separated with the medical equipment, so that the medical equipment can be fixed and disassembled without using disassembly tools, the structure is compact, the operation is convenient, and the use requirement of the medical field is met.

[0058] The above embodiment adopts unilateral driving clamping parts and accommodating grooves to cooperate and fix medical instruments. Considering the stability and balance of the fixed medical instruments, refer to the accompanying drawings Figures 1-3 In another embodiment of the present application, the structure of bilateral driving clamping parts is given, which specifically comprises: a connecting seat 100, the connecting seat 100 is internally provided with an accommodating groove 101 for installing a medical instrument Q, and the two sides of the accommodating groove 101 are both provided with an insertion groove 102 in communication therewith; two groups of the driving clamping parts are arranged on the two sides of the connecting seat 100 corresponding to the insertion grooves 102, the clamping segments of the driving clamping parts on each side can enter or exit the accommodating groove 101 through the insertion groove 102 and combine or separate with the medical instrument Q; one end of each driving clamping part is connected with the switch handle 400 capable of driving it to lock or separate with the medical instrument Q. In this way, any part of the medical instrument that needs to be fixed can be placed into the accommodating groove, and the two groups of driving clamping parts are driven to rotate by the two switch handles, so that the clamping segments of the driving clamping parts on the two sides are respectively locked or separated with the medical instrument on the two sides. Therefore, the fixing and dismounting of the medical instrument can be realized without using dismounting tools, the structure is compact, the operation is convenient, and the use requirements in the medical field are met.

[0059] In the above two embodiments, refer to the accompanying drawings Figure 2 、 5 -7, each group of the driving clamping parts comprises: a driving shaft 200, the driving shaft 200 is provided with at least one cam 201, the number of the cams can be determined according to the size of the installation area of the medical instrument, and two cams 201 are given in the embodiment, and each cam 201 is a whole conjugate cam structure;

[0060] a connecting block 300, and each cam 201 is correspondingly provided with one connecting block 300;

[0061] Wherein, the connecting seat 100 is defined with a connecting area 103 perpendicular to the insertion direction of the insertion groove 102, the driving shaft 200 can rotate in the connecting area 103, the insertion groove 102 communicates the connecting area 103 and the accommodating groove 101, one end of the connecting block 300 is a connecting end 301, the connecting end 301 can move in the connecting area 103, and the other end is a clamping end 302, the clamping end 302 enters or exits the accommodating groove 101 through the insertion groove 102 and combines or separates with the medical instrument Q.

[0062] Advantageously, the top wall and the bottom wall of the connecting seat 100 are arc-shaped, which meets the cooperation requirements with other components, such as the support frame body;

[0063] The height of the clamping end 302 is greater than that of the connecting end 301, and the corners are smoothly connected; refer to the accompanying drawingsFigure 5 Thus, when the clamping end 302 of the connecting block 300 is inserted into or pulled out of the accommodating groove 101, the connecting block 300, the cam 201 and the upper cover 105 and the lower cover 106 are not interfered with each other, thereby ensuring the stability of the movement of the components during the installation and disassembly of the medical instrument.

[0064] Specifically, referring to the accompanying drawings, Figure 4 The clamping end 302 is a horizontal plate, the end of the insertion direction side of which is a transversely arranged quadrangular prism structure, the side away from the insertion direction of which is connected with a vertical connecting plate 303, the bottom of the vertical connecting plate 303 is connected with the connecting end 301, the connecting place is rounded, the side away from the vertical connecting plate 303 of the connecting end 301 is provided with an external baffle 304 which is upwardly protruding and arranged in parallel with the vertical connecting plate 303, the height of the vertical connecting plate 303 is greater than that of the external baffle 304, and the middle part of the connecting end 301 is downwardly penetrated with a groove 305 for accommodating the cam 201.

[0065] It is worth mentioning that the end of the insertion direction of the clamping end 302 adopts the transversely arranged quadrangular prism structure, that is, the cross section of the end of the insertion direction gradually increases from small to large, and the largest cross section coincides with the end of the horizontal plate, thereby playing a guiding and automatic alignment role for the clamping end 302 to enter the insertion groove 102 and providing a structural fault-tolerant design for the sliding fit of the clamping end 302 and the insertion groove 102.

[0066] The two sides of the cam 201 are provided with two inclined angles 202 for limiting the driving shaft 200 and the groove 305, so that the switch handle 400 does not continue to rotate when it is rotated to be perpendicular to the horizontal plane.

[0067] More advantageously, referring to the accompanying drawings, Figure 4 and 5 Since the movement of the clamping end 302 between the insertion groove 102 and the medical instrument Q forms a closed space (i.e. a vacuum is formed during the pulling process), it is inconvenient for the cam 201 to drive the clamping end 302 of the connecting block 300 to enter or pull out, so that the vent hole 306 is arranged on the clamping end 302, so that external gas can enter the inside during the movement, preventing the vacuum from hindering the movement of the connecting block 300; further, the arrangement of the vent hole reduces the contact area of the clamping end 302 and the contact component, thereby reducing the movement friction of the connecting block 300 and facilitating the pushing and pulling movement of the cam 201.

[0068] The existing cam return mode adopts a spring, but in the medical field, especially in the nuclear magnetic environment, materials that interfere with the use cannot be used, and a pair of conjugate cams are also used, one of which realizes the lifting and the other realizes the return, and the two are used in cooperation, but the space arrangement on the medical equipment is limited, and the use of multiple double cam structures is not conducive to the space arrangement. In view of this, in some other embodiments of the present application, referring to the accompanying drawings,Figure 5 The cam 201 has opposite lift curve and return curve on its outer surface, the sum of the distance from the lift curve to the vertical connecting plate 303 and the outer baffle 304 is equal to the sum of the distance from the return curve to the vertical connecting plate 303 and the outer baffle 304, and the outer surface of the cam 201 is always in contact with the vertical connecting plate 303 and the outer baffle 304 in any state. Two inclined angles 202 are arranged near the base circle of the lift curve or the return curve.

[0069] Therefore, the lift and return are realized by one cam, and the two inclined angles on the cam are used for limiting, which improves the space utilization of the device and makes the structure more compact.

[0070] In the above embodiments, the switch handle 400 can be manually or electrically controlled, and the switch handle 400 does not need to be separately provided with a locking part. If manual control is used, a locking part 500 can be added in the above embodiments, one end of the connecting seat 100 close to the switch handle 400 is detachably provided with the locking part 500, and the switch handle 400 can be locked or separated from the locking part 500. The locking part 500 can be cylindrical, and in one specific embodiment, it can be a locking screw; the locking screw can be replaced after wear.

[0071] Specifically, one end of the switch handle 400 is connected to one end of the drive shaft 200 through a set screw 104 and located outside the connecting seat 100, and the other end is provided with a hook 401 close to the locking part 500. The hook 401 is made of high polymer composite material and has good wear resistance, the pulling force between the hook 401 and the locking part 500 is less than 5N and greater than the locking force, so that the pulling force is more conducive to manual operation.

[0072] On the basis of the above embodiments, if two switch handles are used, the width of the hook 401 is half of the width of the switch handle 400, and is arranged on one side of the other end surface of the switch handle 400; thus, the two handles are hung on the locking part and arranged staggered, without interfering with each other, and the two handles can be interchanged, which increases the interchangeability of parts and reduces the manufacturing cost.

[0073] In the above embodiments, referring to the accompanying drawings, Figure 2 The connecting seat 100 can include:

[0074] An upper cover 105, which is an arc-shaped cover and has two first end surfaces arranged in parallel at both ends corresponding to the length direction of the drive shaft 200;

[0075] A lower cover 106, which is an arc-shaped cover, has two second end faces opposite two first end faces, and can be buckled with the upper cover 105;

[0076] A connecting frame 107, which is a rectangular frame, is located between the upper cover 105 and the lower cover 106, and a middle part of the connecting frame 107 forms the accommodating groove 101, and the lower cover 106 is provided with an access hole 1061 corresponding to the accommodating groove 101; and the insertion groove 102 is located on a side wall of the connecting frame 107.

[0077] The first and second reinforcing beams 108 and 109 are respectively fixedly connected between the front and rear end faces of the connecting frame 107 and the two first end faces or the two second end faces; the two ends of the drive shaft 200 are hingedly connected to the hinge holes of the first and second reinforcing beams 108 and 109, and extend out of the first and second end faces; and the connecting area 103 is an area enclosed by the upper cover 105, the lower cover 106, the first and second reinforcing beams 108 and 109, and the connecting frame 107. Figure 3 The locking part 500 passes through the second reinforcing beam 109 and extends outward, and the second reinforcing beam 109 and the connecting frame 107 form a limit, so that the locking part 500 can be directly disassembled and replaced after wearing.

[0078] In the above scheme of the connecting seat 100, the upper cover 105, the lower cover 106, and the first and second reinforcing beams 108 and 109 can be provided as needed, or the structure can be simplified to directly use corresponding mounting parts or equipment housings to accommodate or limit the above other parts.

[0079] Another object of the application discloses a support device, which comprises a support frame body 600, which is arc-shaped and has an accommodating cavity with an opening downward in a middle part; and the connecting mechanism of any one of the above embodiments, wherein the connecting seat 100 of the connecting mechanism is installed in the accommodating cavity, the drive shaft 200 of the connecting mechanism rotates on the support frame body 600, and the switch handle 400 is located outside the support frame body 600. Figure 8 The base of the medical instrument Q is provided with an instrument access groove Q1, and the clamping segment of the drive clamping part of the connecting mechanism can enter or exit the access groove Q1 through the insertion groove 102. 9 Therefore, the connecting seat of the connecting mechanism is installed in the accommodating cavity, the base of the medical instrument is placed in the accommodating groove, the drive clamping part is driven to rotate through the switch handle, and then the clamping segment enters or exits the access groove through the insertion groove, so that the installation and disassembly of the medical instrument and the support frame are realized, the operation is simple, and the use scene requirement is met.

[0080] It is worth mentioning that the integral connecting seat 100 structure can be directly installed on the support frame body 600, or the upper cover 105, the lower cover 106, and the first and second reinforcing beams 108 and 109 can be directly formed by using the shell structure on the support frame body 600 to simplify the structural design.

[0081] In the above embodiment, the manual control switch handle can be extended from one end of the support frame body 600 by using the locking part 500 of the connecting mechanism, and the hook 401 of the switch handle 400 is hung on the locking part 500. One handle switch can be controlled on one side, or two handle switches can be controlled on both sides.

[0082] In the above embodiment, the outer contour surface of the switch handle 400 and the hook 401 does not exceed the upper and lower wall surfaces of the support frame body 600, so that the medical instrument Q does not occupy the external space of the support frame after being installed, and the structure is compact and has good aesthetics.

[0083] In use, referring to FIG. 8, the medical instrument Q is placed on the support frame body 600, and the switch handle 400 is rotated from the lower end to the upper end, and the hook 401 is hung on the locking part 500 of the connecting mechanism, so that the switch handle 400 is locked and cannot be rotated. Figure 8 When the switch handle is rotated from the lower end to the upper end, the locking part can fix the switch handle so that it cannot be rotated. When the switch handle is pressed from the upper end to the lower end, it is separated from the locking part, and at this time the switch handle can be rotated. When the switch handle is locked, it is attached to the outside of the support frame body, which can save space. When the driving shaft is rotated, the cam drives the connecting block to rotate, and the two inclined angles of the cam limit the driving shaft and the connecting block, so that the switch handle cannot continue to rotate when it is rotated to be perpendicular to the horizontal plane, or it cannot rotate when it is rotated to the locking part. When the connecting block is pulled back and forth to slide under the rotation of the driving shaft, the medical instrument base can be fixed or loosened.
