Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical technology, and particularly to a clamping device. Background Art
[0002] The current clamping technology for hydrodynamic treatment devices is mainly as follows: The hand-held insertion body is vertically inserted into the pump port until it reaches the proper position, and then the clamping mechanism is operated a second time to lock and achieve clamping. First, the above-mentioned clamping technology for hydrodynamic treatment devices has the characteristic of complex structure. For example, in order to achieve clamping, a relatively complex crank locking mechanism is adopted, etc., which greatly increases the manufacturing cost of the device. Second, there is inevitably a gap between the limiting wing of the insertion body and the fixed seat in this clamping method. Driven by the reciprocating movement of the internal components of the insertion body, the insertion body usually has the phenomenon of reciprocating impact on the clamping structure, and this phenomenon is often accompanied by noise, seriously polluting the environment of medical institutions. Third, the above structure lacks a certain sense of damping during the operation process. Therefore, it is necessary to design a new insertion body clamping device with a simple structure, provide a certain tactile feedback during the insertion process, reduce the noise caused by reciprocating movement, and achieve reliable clamping after the insertion body is inserted in place. Therefore, there is an urgent need for a new type of clamping device to solve the above problems. Summary of the Invention
[0003] The purpose of the present application is to provide a clamping device to achieve reliable clamping and improve the user experience.
[0004] The purpose of the present application is achieved through the following technical solutions:
[0005] A clamping device includes: a first seat body, a second seat body, an insertion body, a bushing, a first elastic member, and a locking bracket. The second seat body is rotatably inserted into the first seat body in a first axial direction, the insertion body is rotatably inserted into the second seat body in a second axial direction opposite to the first direction. There is a gap between the first seat body and the second seat body in the circumferential direction. The locking bracket, the first elastic member, and the bushing are sequentially arranged in the gap in the first direction, and the locking bracket is threadedly connected to the first seat body;
[0006] Wherein, a limiting structure is provided at the first end of the first seat body, a first limiting block is provided on the insertion body, and the insertion body can rotate in the second seat body so that the limiting structure and the first limiting block are clamped and limited or separated from each other in the first direction.
[0007] In some embodiments of the present application, a first through hole is opened at the first end of the first seat body. The first through hole includes a first selectively passing port. The first limiting block is adapted to the shape of the first selectively passing port. The shape of the first through hole is adapted to the axial projection shapes of the insertion body and the first limiting block, and the limiting structure is arranged on the outer periphery of the first through hole.
[0008] In some embodiments of the present application, a second limiting block is further provided on the insert body. The first through opening includes a second selectively passing opening. The second limiting block is adapted to the shape of the second selectively passing opening, and the second limiting block can be clamped and limited with the limiting structure or separated from each other in the first direction.
[0009] In some embodiments of the present application, a third limiting block is further included. A limiting groove is circumferentially formed on the first seat body. The third limiting block passes through the limiting groove and is fixedly installed on the second seat body. The limiting groove defines a rotation space in the circumferential direction, and the third limiting block can rotate within the rotation space.
[0010] In some embodiments of the present application, the third limiting block is a magnetic member, and the first seat body can be magnetically adsorbed to the third limiting block.
[0011] In some embodiments of the present application, a proximity switch is further included. The proximity switch is installed on one side of the first seat body, and the sensor of the proximity switch faces the limiting groove. The third limiting block rotates within the rotation space to approach or move away from the proximity switch.
[0012] In some embodiments of the present application, the first limiting block and the second limiting block are oppositely arranged on the outer periphery of the insert body, and the projection shapes of the first limiting block and the second limiting block in the first direction are the same.
[0013] In some embodiments of the present application, a first step is provided at the first end of the first seat body, and the projection of the second seat body in the first direction at least partially coincides with the first step.
[0014] In some embodiments of the present application, a second step is further provided on the inner side wall of the first seat body. A convex block is provided on the side wall of the second seat body close to the first seat body. The projection of the convex block in the first direction at least partially coincides with the second step, and the projection of the shaft sleeve in the second direction completely coincides with the convex block.
[0015] In some embodiments of the present application, a second elastic member is provided between the second step and the convex block.
[0016] For the clamping device of the present application, when the insert is inserted into the second seat body, the second seat body can be continuously pressed down in the first seat body, so that the second seat body drives the bushing to press down. The bushing continuously compresses the first elastic member, making its reaction elastic force increase continuously, thereby obtaining an increasingly large damping feel feedback. The threaded connection of the locking bracket can adjust the locking depth to adjust the damping size during the insertion process of the insert and provide a suitable feel. At the same time, the first seat body and the insert are clamped and limited through the limiting structure and the first limiting block. Cooperating with the first elastic member can eliminate the gaps between various parts, reduce vibration and operating noise, and ensure a silent medical environment. As the insert rotates, the limiting structure and the first limiting block can be separated from each other, and under the elastic action of the first elastic member, the insert disengages from the second seat body, thus realizing the separation between the insert and the second seat body.

[0027] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

Therefore, it cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0029] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. It can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] As Figure 1-8 shown, an embodiment of the present application provides a clamping device, including: a first seat body 1, a second seat body 2, an insertion body 3, a bushing 4, a first elastic member 5, and a locking bracket 6. The second seat body 2 is rotatably inserted into the first seat body 1 along the first direction X in the axial direction. The insertion body 3 is rotatably inserted into the second seat body 2 along the second direction Y in the axial direction. The first direction X and the second direction Y are opposite. There is a gap 7 between the first seat body 1 and the second seat body 2 in the circumferential direction. The locking bracket 6, the first elastic member 5, and the bushing 4 are sequentially arranged in the gap 7 along the first direction X, and the locking bracket 6 is threadedly connected to the first seat body 1. Wherein, a limiting structure 101 is provided at the first end of the first seat body 1, and a first limiting block 301 is provided on the insertion body 3. The insertion body 3 can rotate in the second seat body 2 so that the limiting structure 101 and the first limiting block 301 are clamped and limited or separated from each other in the first direction X.
[0031] Based on the above technical solution, for the clamping device of the present application, when the insertion body 3 is inserted into the second seat body 2, the second seat body 2 can be continuously pressed down in the first seat body 1, so that the second seat body 2 drives the bushing 4 to press down. The bushing 4 continuously compresses the first elastic member 5, making its reaction elastic force increase continuously, so as to obtain an increasingly large damping feel feedback. The threaded connection of the locking bracket 6 can adjust the locking depth thereof to adjust the damping size during the insertion process of the insertion body 3 and provide a suitable feel. At the same time, the first seat body 1 and the insertion body 3 are clamped and limited through the limiting structure 101 and the first limiting block 301. Cooperating with the first elastic member 5, the gap 7 between various parts can be eliminated, vibration and running noise can be reduced, and a silent medical environment can be ensured. As the insertion body 3 rotates, the limiting structure 101 and the first limiting block 301 can be separated from each other, and under the elastic action of the first elastic member 5, the insertion body 3 is separated from the second seat body 2, thereby realizing the separation between the insertion body 3 and the second seat body 2.
[0032] In some embodiments of the present application, as Figure 3 , 5 shown in FIG. 6, a first through port 102 is formed at the first end of the first seat body 1. The first through port 102 includes a first selectively passing port 1021. The first limiting block 301 is adapted to the shape of the first selectively passing port 1021. The shape of the first through port 102 is adapted to the axial projection shapes of the insertion body 3 and the first limiting block 301. The limiting structure 101 is arranged on the outer periphery of the first through port 102. The first through port 102 allows the insertion body 3 and the first limiting block 301 to pass through. As the insertion body 3 extends into the second seat body 2, the first limiting block 301 axially exceeds the first selectively passing port 1021, and then the insertion body 3 is rotated, which can drive the first limiting block 301 to rotate. At this time, the insertion body 3 is released. Under the action of the first elastic member 5, the second seat body 2 presses the first limiting block 301 against the limiting structure 101. This clamping method is simple and practical. The shape of the first through port 102 can be an irregular shape, such as an eccentric wheel, etc.
[0033] Specifically, as Figure 5 , 8As shown, a second limiting block 302 is further provided on the insert body 3. The first through port 102 includes a second selectively passing port 1022. The second limiting block 302 is adapted to the shape of the second selectively passing port 1022. The second limiting block 302 can be clamped and limited or separated from the limiting structure 101 in the first direction X. The function of the second limiting block 302 is the same as that of the first limiting block 301, and both can achieve axial clamping, thereby further improving the clamping effect. Moreover, when the shapes of the second limiting block 302 and the first limiting block 301 are different, the purpose of inserting the insert body 3 in a unique angle in the circumferential direction can be achieved; when the shapes of the second limiting block 302 and the first limiting block 301 are the same and are evenly spaced from the first limiting block 301, the insert body 3 can be inserted at multiple angles to achieve the purpose of convenient insertion.
[0034] More specifically, as Figure 1-5 shown, a third limiting block 8 is further included. The first seat body 1 is circumferentially provided with a limiting groove 9. The third limiting block 8 passes through the limiting groove 9 and is fixedly installed on the second seat body 2. The limiting groove 9 defines a rotation space 10 in the circumferential direction. The third limiting block 8 can rotate within the rotation space 10. The third limiting block 8 and the limiting groove 9 are used in cooperation. The limiting groove 9 plays a role in circumferential limiting, so that the third limiting block 8 can only rotate within a certain range. The purpose is to prevent the second seat body 2 from rotating without limit. When it rotates to a position where the first limiting block 301 corresponds to the first selectively passing port 1021 and the second limiting block 302 corresponds to the second selectively passing port 1022, under the action of the first elastic member 5, the insert body 3 will pop out of the second seat body 2, causing the clamping device to fail. Therefore, the third limiting block 8 and the limiting groove 9 are needed to limit the rotation of the second seat body 2. It should be noted that since there is a possibility that the first limiting block 301 and the second limiting block 302 are evenly spaced, this will enable the insert body 3 to be inserted at multiple angles. Therefore, when the insert body 3 can be inserted at multiple angles, the rotation space 10 defined by the limiting groove 9 should be smaller, so that the insert body 3 rotates and clamps between two adjacent insertion positions to prevent the insert body 3 from popping out.
[0035] More specifically, as Figure 1-4 shown, the third limiting block 8 is a magnetic member, and the first seat body 1 can be magnetically adsorbed to the third limiting block 8. The magnetic adsorption between the third limiting block 8 and the first seat body 1 can prevent the circumferential release of the insert body 3 during operation and avoid its rotation and detachment from the second seat body 2 due to vibration or other reasons.
[0036] More specifically, as Figure 1-5As shown, it further includes a proximity switch 11. The proximity switch 11 is installed on one side of the first housing 1, and the sensor of the proximity switch 11 faces the limiting groove 9. The third limiting block 8 rotates within the rotating space 10 to approach or move away from the proximity switch 11. The proximity switch 11 is a position switch that can operate without mechanical direct contact with moving parts. When the third limiting block 8 rotates into place, the proximity switch 11 can sense the third limiting block 8, thereby issuing instructions such as starting work or ending work to the control unit.
[0037] In some embodiments of the present application, as Figure 5 , 8 shown, the first limiting block 301 and the second limiting block 302 are oppositely arranged on the outer periphery of the insert 3, and the projection shapes of the first limiting block 301 and the second limiting block 302 in the first direction X are the same. When the shapes of the first limiting block 301 and the second limiting block 302 are the same, the insert 3 has a higher degree of freedom of passage in the first direction X, that is, the first limiting block 301 can pass through the first selective passage port 1021 or the second selective passage port 1022, and the second limiting block 302 can pass through the first selective passage port 1021 or the second selective passage port 1022, which makes it easier for the insert 3 to be inserted into the second housing 2.
[0038] In some embodiments of the present application, as Figure 3 , 5 shown, the first end of the first housing 1 is provided with a first step 103, and the projection of the second housing 2 in the first direction X at least partially coincides with the first step 103. The first step 103 can play an axial limiting role on the second housing 2. During the process of the second housing 2 being installed into the first housing 1, when the second housing 2 abuts against the first step 103, the second housing 2 can no longer move in the installation direction, that is, the second housing 2 is installed in place.
[0039] Specifically, as Figure 3 , 5 , 7 shown, the inner side wall of the first housing 1 is further provided with a second step 104. The side wall of the second housing 2 close to the first housing 1 is provided with a convex block 201. The projection of the convex block 201 in the first direction X at least partially coincides with the second step 104, and the projection of the bushing 4 in the second direction Y completely coincides with the convex block 201. The second step 104 can cooperate with the convex block 201 to achieve axial limiting of the second housing 2, thereby assisting the first step 103 to further achieve more stable axial limiting of the second housing 2, and by restricting the axial movement of the bushing 4 through the convex block 201, problems such as the bushing 4 falling off can be effectively avoided.
[0040] More specifically, as Figure 3 and 5 shown, a second elastic member 12 is provided between the second step 104 and the bump 201. The second elastic member 12 can play a buffering role, effectively improving safety during the installation of the second seat body 2 or during the operation of the clamping device, and reducing the vibration of the clamping device.
[0041] In summary, for the clamping device of the present application, when the insert 3 is inserted into the second seat body 2, the second seat body 2 can be continuously pressed down in the first seat body 1, so that the second seat body 2 drives the bushing 4 to press down. The bushing 4 continuously compresses the first elastic member 5, making its reaction elastic force larger and larger, so as to obtain an increasingly large damping feel feedback. The threaded connection of the locking bracket 6 can adjust the locking depth to adjust the damping size during the insertion process of the insert 3, providing a suitable feel. At the same time, the first seat body 1 and the insert 3 are clamped and limited by the limiting structure 101 and the first limiting block 301. Cooperating with the first elastic member 5, the gap 7 between each part can be eliminated, reducing vibration and operating noise, and ensuring a quiet medical environment. As the insert 3 rotates, the limiting structure 101 and the first limiting block 301 can be separated from each other, and under the elastic action of the first elastic member 5, the insert 3 is separated from the second seat body 2, thus realizing the separation between the insert 3 and the second seat body 2.
[0042] The above is only the preferred embodiment of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present application.
