Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
As shown in fig. 1 to 7, the buoy for puncture needle according to the embodiment of the present invention includes a first housing cover 1, a second housing cover 4, and a sliding member 2, wherein the first housing cover 1 and the second housing cover 4 are fixedly connected to form a housing, the sliding member 2 penetrates the second housing cover 4 along the length direction of the second housing cover 4 and is movably disposed in the first housing cover 1, and the end of the sliding member 2 and the first end of the first housing cover 1 are used for clamping the puncture needle. The second housing cover 4 serves to limit the position of the slide module 2 so that the slide module 2 is not easily detached from the first housing cover 1.
The buoy also comprises an elastic component, a force application component and a guide component, wherein the force application component drives the sliding component 2 to be far away from the first end of the first shell cover 1 under the guide action of the guide component when receiving external force; an elastic component is arranged in the shell, and under the action of the elastic component, a clamping force can be formed between the end part of the sliding component 2 and the first end of the first shell cover 1.
When the puncture needle 5 is assembled, by applying force to the force application part, the sliding component 2 moves towards the direction far away from the first end of the first shell cover 1 under the action of the belt direction of the guide part, so that a gap is formed between the sliding component 2 and the first shell cover 1, the puncture needle 5 penetrates through the gap, under the action of the elastic part or the friction force, the sliding component 2 and the first shell cover 1 clamp the puncture needle, so that the puncture needle 5 is assembled between the sliding component 2 and the first shell cover 1, and the size of the gap can be adjusted through the force application part, so that the buoy can be used for assembling puncture needles 5 with different diameters.
The first shell cover 1 comprises a base plate and a clamping plate 11, a first end of the clamping plate 11 is connected with an end portion of the base plate, and a second end of the clamping plate 11, serving as a first end of the first shell cover 1, is positioned above the base plate; the sliding assembly 2 is limited, and the risk that the sliding assembly 2 slides out of the sliding groove 13 is reduced; the guide component is a sliding chute 13 which is arranged on the substrate along the length direction of the substrate, the sliding chute 13 is positioned in the middle of the substrate, and the length of the sliding chute 13 is the same as that of the substrate; on the substrate, one or more slots 12 are disposed on both sides of the sliding slot 13 for fixing the second housing cover 4 to the first housing cover 1. The engaging plate 11 is an arc-shaped plate or a folded plate, but is not limited thereto. The number of the card slots 12 on the two sides of the sliding slot 13 is the same, and the card slots 12 are arranged in an axisymmetric manner, for example, when the number of the card slots 12 is 4, the number of the card slots 12 on the two sides of the sliding slot 13 is two on the substrate. With this arrangement, the connection of the second housing cover 4 to the second housing cover 4 can be strengthened, so that the slide module 2 is less likely to deviate from the slide groove 13.
The second housing cover 4 is further provided with a locking hook 41 matched with the locking slot 12, and the second housing cover 4 is fixed on the first housing cover 1 through the matching of the locking slot 12 and the locking hook 41.
A first opening 43 is formed in the top of the second housing cover 4 along the length direction, the first opening 43 is located in the center of the top of the second housing cover 4, a second opening 44 is formed in one end, close to the clamping plate 11, of the second housing cover 4, a stop 42 is arranged at one end, away from the clamping plate 11, of the second housing cover 4, and the stop 42 covers the end portion of the substrate. The stopper 42 may block the sliding assembly 2 from escaping from the chute 13. The second opening 44 may be an arc-shaped opening, and may also be a rectangular or polygonal opening. The shape of the first opening 43 may be oval, circular, rectangular, polygonal, and the like. The length of the first opening 43 can be determined according to actual requirements, and when the diameter of the puncture needle 5 is larger, the size of the gap formed between the first housing cover 1 and the sliding assembly 2 is larger, and the length of the first opening 43 is also larger.
The first end of the sliding component 2 is a force application part, the second end is a locking block 21, and the force application part is connected with the locking block 21 through a sliding body. The sliding body penetrates through the second opening 44 and is movably arranged in the sliding groove 13, and the locking block 21 is positioned outside the second shell cover 4; the force application member is located inside the second housing cover 4 and protrudes out of the first opening 43. The elastic member is a compression spring 3 and is disposed between the urging member and the stopper 42. The force applying member is a handle 22. Namely, one end of the compression spring 3 abuts against the stopper 42, and the other end abuts against the handle 22.
When the buoy of the invention is assembled with the puncture needle 5, a user pushes the handle 22 to move towards one side of the pressure spring 3 (the pressure spring 3 is compressed), the locking block 21 is separated from the clamping plate 11, the sliding body moves towards one side far away from the clamping plate 11 along the sliding groove 13 until the gap between the locking block 21 and the clamping plate 11 is larger than the diameter of the puncture needle 5, the user stops pushing the handle 22, the puncture needle 5 is then inserted through the space, the position of the puncture needle 5 is adjusted, the user releases the handle 22, due to the thrust of the pressure spring 3, the sliding body moves to one side of the puncture needle 5 along the sliding groove 13 until the locking block 21 moves to the puncture needle 5 and stops, due to the thrust of the pressure spring 3, the lock block 21 and the clamping plate 11 clamp the puncture needle 5, when the puncture operation is finished, the user pushes the handle 22 to move towards the compression spring 3, the locking block 21 moves towards the direction far away from the puncture needle 5, and the puncture needle 5 can be taken away from the buoy.
The above-described embodiments should not be construed as limiting the scope of the invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
