Specific embodiments

[0030] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0031] As shown in the attached Figure 1 to the attached Figure 4 As shown: An infusion hose with an anti-disconnection structure includes a hose body 1 and a connecting seat 2. The hose body 1 is provided with a circular connecting piece 11 along the liquid inlet end. A puncture head 12 is vertically installed at the center end of the top of the connecting piece 11. The puncture head 12 is in communication with the hose body 1. In this way, the liquid medicine in the infusion bottle can be introduced into the hose body 1 through the puncture head 12. An inner cavity 21 is formed in the connecting seat 2. The inner cavity 21 is provided with a first opening 22 communicating from the center end to the top surface of the connecting seat 2. A fixing sleeve 3 is fixedly arranged at the first opening 22. The top surface of the fixing sleeve 3 is provided with a circular cavity, and the cavity is adapted to the connecting piece 11. The inner cavity 21 is provided with a second opening 23 communicating from the center end to the bottom surface of the fixing sleeve 3. Subsequently, a third opening 31 is communicated between the bottom surface of the fixing sleeve 3 and the bottom end surface of the cavity. When the connecting piece 11 on the hose body 1 is properly placed in the cavity of the fixing sleeve 3, the other end of the hose body 1 can pass through the third opening 31 and the second opening 23. In this way, the assembly process between the entire hose body 1 and the connecting seat 2 can be realized.

[0032] In the above embodiments, since the connecting piece 11 is arranged at the liquid inlet end of the leather tube body 1, when the leather tube body 1 is assembled with the connecting seat 2, first, the liquid outlet end of the leather tube body 1 is passed through the third opening 31 and the second opening 23, and then the leather tube body 1 is pulled. At this time, the liquid inlet end of the leather tube body 1 can drive the connecting piece 11 to be adaptively clamped into the cavity of the fixing sleeve 3, so that the assembly of the leather tube body 1 and the connecting seat 2 can be completed. And after the assembly, the connecting seat 2 can bear the tensile force together (that is, when the leather tube body 1 is subjected to a downward tensile force).

[0033] Further, to improve the assembly convenience of the leather tube body 1 and the connecting seat 2, the height of the connecting piece 11 is adaptively set with the height of the cavity of the fixing sleeve 3. Through such a design, the top surfaces of the connecting piece 11 and the connecting seat 2 can be flush with each other. After being flush, it is convenient for the user to accurately grasp the puncture head 12, so that when the puncture head 12 is inserted into the infusion bottle, it can be more accurate.

[0034] As Figure 1 and Figure 4 shown, to facilitate the connection of the connecting seat 2 with the infusion bottle, a first clamping block 56 and a second clamping block 65 are slidably arranged at the left side and the right side of the upper end of the top of the connecting seat 2. The first clamping block 56 and the second clamping block 65 are arranged oppositely, and the adjacent ends of the first clamping block 56 and the second clamping block 65 are in an L-shaped structure. At the same time, a semi-circular first clamping groove 57 is opened at the top end of the inner side surface of the first clamping block 56, and a semi-circular second clamping groove 66 is opened at the top end of the inner side surface of the second clamping block 65. The first clamping groove 57 and the second clamping groove 66 are arranged oppositely, and the first clamping groove 57 and the second clamping groove 66 are adapted to the bottle mouth ring structure of the infusion bottle.

[0035] In the above embodiments, by slidably arranging a first clamping block 56 and a second clamping block 65 at the left side and the right side of the top of the connecting seat 2, and clamping grooves adapted to the bottle mouth ring of the infusion bottle are also opened at the first clamping block 56 and the second clamping block 65. In this way, during use, the first clamping block 56 and the second clamping block 65 can be placed on the left and right sides of the infusion bottle, and then the first clamping block 56 and the second clamping block 65 are moved close to the upper part of the bottle mouth ring of the infusion bottle. When the clamping grooves of the first clamping block 56 and the second clamping block 65 clamp the outer wall of the infusion bottle, the L ends of the first clamping block 56 and the second clamping block 65 can be pressed on the upper surface of the bottle mouth ring. At this time, the connecting seat 2 can be suspended below the infusion bottle through the first clamping block 56 and the second hanging block, so that the connecting seat 2 can be fixed at the lower end of the infusion bottle, thereby realizing the stable connection between the leather tube body 1 and the infusion bottle.

[0036] As Figure 1 and Figure 3As shown in the figure, for the convenience of moving the first clamping block 56 and the second clamping block 65, a first transmission mechanism and a second transmission mechanism are provided on the rear side and the front side of the inner wall of the inner cavity 21 respectively. The first transmission mechanism includes a first sliding groove 5, a first sliding strip 51, a first spring 52, a first connecting block 53 and a first sub-connecting block 54. The first sliding groove 5 is linearly opened on the rear side of the inner wall of the inner cavity 21. The first sliding strip 51 is slidably arranged at the right side inside the first sliding groove 5. The first spring 52 is arranged at the left side inside the first sliding groove 5. Then, one end of the first spring 52 is also connected to the first sliding strip 51. The first connecting block 53 is fixedly arranged on the left side of the front surface of the first sliding strip 51 in the front-rear direction, and the first connecting block 53 extends towards the middle of the inner cavity 21. The first sub-connecting block 54 is fixedly arranged on the extension of the first connecting block 53 in the up-down direction. In this way, the first sliding strip 51 can drive the first sub-connecting block 54 to move towards the left side. After the movement, it can be reset according to the elastic force of the first spring 52;

[0037] The second transmission mechanism includes a second sliding groove 6, a second sliding strip 61, a second spring 62, a second connecting block 63 and a second sub-connecting block 64. The second sliding groove 6 is linearly opened on the front side of the inner wall of the inner cavity 21. The second sliding strip 61 is slidably arranged at the left side inside the second sliding groove 6. The second spring 62 is arranged at the right side inside the second sliding groove 6. Then, one end of the second spring 62 is connected to the second sliding strip 61. The second connecting block 63 is fixedly arranged on the right side of the rear surface of the second sliding strip 61 in the front-rear direction, and one end of the second connecting block 63 extends towards the middle of the inner cavity 21. The second sub-connecting block 64 is fixedly arranged on the extension of the second connecting block 63 in the up-down direction. In this way, the second sliding strip 61 can drive the second sub-connecting block 64 to move towards the right side. After the movement, it can be reset according to the elastic force of the second spring 62.

[0038] In addition, communication grooves 55 are respectively opened on the upper surface of the connecting seat 2 along the lower sides of the first clamping block 56 and the second clamping block 65. The communication grooves 55 include a first communication groove 55 and a second communication groove 55. The first communication groove 55 and the second communication groove 55 are both communicated with the inner cavity 21. The first communication groove 55 is arranged opposite to the first sub-connecting block 54, and the upper end of the first sub-connecting block 54 passes through the first communication groove 55 and is fixedly connected to the lower surface of the first clamping block 56. The second communication groove 55 is arranged opposite to the second sub-connecting block 64, and the upper end of the second sub-connecting block 64 passes through the second communication groove 55 and is fixedly connected to the lower surface of the second clamping block 65.

[0039] In the above embodiment, by providing the first transmission mechanism and the second transmission mechanism, when the first transmission mechanism and the second transmission mechanism move together, they can drive the first clamping block 56 and the second clamping block 65 to move outward simultaneously. At the same time, the first spring 52 and the second spring 62 can force the first clamping block 56 and the second clamping block 65 to move inward together, so that it is convenient for the first clamping block 56 and the second clamping block 65 to be stably suspended at the position of the bottle mouth ring of the infusion bottle.

[0040] As Figure 2 and Figure 3 shown, to facilitate the control of the movement of the first transmission mechanism and the second transmission mechanism, a rotating sleeve 4 with an annular structure is rotatably provided on the outer wall of the fixed sleeve 3. The rotating sleeve 4 is located between the first sliding strip 51 and the second sliding strip 61. At the same time, a gear 41 is fixedly provided on the outer wall surface of the rotating sleeve 4. The gear 41 faces the first sliding strip 51 and the second sliding strip 61. Subsequently, a first rack 511 is fixedly provided at the right side of the front surface of the first sliding strip 51. The first rack 511 meshes with the rear surface of the gear 41. And a second rack 611 is fixedly provided at the left side of the rear surface of the second sliding strip 61. The second rack 611 meshes with the front surface of the gear 41. In this way, when in use, the rotating sleeve 4 can be rotated counterclockwise. When the rotating sleeve 4 rotates, it can exert a thrust on the first rack 511 and the second rack 611 through the gear 41, so that the first clamping block 56 and the second clamping block 65 can be controlled to move simultaneously.

[0041] Furthermore, to increase the usability of the rotating sleeve 4, the lower end of the rotating sleeve 4 passes through the second opening 23 and extends downward below the connecting seat 2, so that in use, it is convenient for the user to better hold the rotating sleeve 4.

[0042] The following is the specific working process of the solution of the present utility model:

[0043] First, place the infusion end of the hose body 1 in the cavity of the fixed sleeve 3, then let the infusion end of the hose body 1 pass through the third opening 31 on the fixed sleeve 3, and then let the connecting piece 11 on the hose body 1 be snap-fitted with the cavity on the fixed sleeve 3, so that the assembly of the hose body 1 and the connecting seat 2 is completed. Then manually rotate the rotating sleeve 4 counterclockwise. At this time, the gear 41 on the rotating sleeve 4 will be in meshing contact with the racks on the first sliding strip 51 and the second sliding strip 61, so that the first sliding strip 51 and the second sliding strip 61 can be driven to move outward simultaneously, thereby expanding the first clamping block 56 and the second clamping block 65.

[0044] After the first clamping block 56 and the second clamping block 65 are expanded, the puncture head 12 on the top of the connecting seat 2 is inserted into the rubber stopper at the mouth of the infusion bottle. During the insertion process, the first clamping block 56 and the second clamping block 65 can be moved above the mouth ring of the infusion bottle, and then the rotating sleeve 4 is released. At this time, the first spring 52 and the second spring 62 will force the first sliding bar 51 and the second sliding bar 61 to reset, so that the L ends of the first clamping block 56 and the second clamping block 65 can be pressed on the upper surface of the mouth ring. At this time, the connecting seat 2 can be suspended below the infusion bottle through the first clamping block 56 and the second hanging block. Since the hose body 1 is snap-fitted on the connecting seat 2 through the connecting piece 11, when the hose body 1 is pulled by an external force (such as being pulled downward), a stable anti-disconnection effect can be achieved.

[0045] In addition, since the connecting seat 2 and the hose body 1 are connected in a snap-fit manner, when the hose body 1 is in use, it can be detached from the connecting seat 2. After detachment, it is convenient to install a new hose body 1 for use.

[0046] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed by the present application can still modify the technical solutions described in the foregoing embodiments or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered by the protection scope of the present application.
