Description

Technical Field

[0001] The present application relates to the technical field of clamping fixtures, and in particular to a fixing device and a reagent filling device. Background Art

[0002] Test kits are widely used in the fields of medical and food packaging.

[0039] The embodiments of the present application provide a fixing device and a reagent filling device, which are used to solve the technical problem of unstable force on the reagent box.

[0040] In the embodiments of the present application, Figures 1 to 3 As shown, the fixing device includes a base 1, a connecting component 2, a support member 3, an elastic member 4 and an adsorption platform 5. A positioning hole 11 is provided on the base 1, and the positioning hole 11 passes through the base 1. The connecting component 2 is provided on the base 1, and the support member 3 is provided on the connecting component 2, and the support member 3 is spaced apart from the base 1. One end of the elastic member 4 is provided on the support member 3, and the adsorption platform 5 is provided at one end of the elastic member 4 away from the support member 3, and the adsorption platform 5 extends into the positioning hole 11. Among them, the elastic member 4 can be a spring.

[0041] like Figure 1 As shown, the fixing device of this embodiment can be used to fix the reagent box 7, and the cross-sectional shape of the reagent box 7 is an arc shape. After the fixing device adsorbs and fixes the reagent box 7, the reagent can be injected into the reagent box 7. After that, the reagent box 7 can also be heat-sealed using a heat-sealing film 8.

[0042] like Figure 1 and Figure 4 As shown, the adsorption platform 5 is provided with adsorption holes so as to adsorb the reagent box 7 by vacuuming, thereby fixing the reagent box 7 on the adsorption platform 5. The base 1 is provided with a positioning hole 11, which penetrates the base 1, and the adsorption platform 5 extends into the positioning hole 11. Therefore, after the reagent box 7 is placed in the positioning hole 11, the reagent box 7 can be adsorbed and fixed by the adsorption platform 5, thereby fixing the reagent box 7 in the positioning hole 11. The groove wall of the positioning hole 11 can limit the position of the reagent box 7, so as to position the reagent box 7.

[0043] The connecting component 2 is arranged on the base 1, and the supporting member 3 is arranged on the connecting component 2 to support the supporting member 3 through the connecting component 2. The supporting member 3 is spaced apart from the base 1 so that an elastic member 4 is arranged on the supporting member 3, and the adsorption platform 5 is supported by the elastic member 4 so that the adsorption platform 5 extends into the positioning hole 11. The supporting member 3 may be a plate-like structure.

[0044] A positioning hole 11 is provided on the base 1 of the embodiment of the present application, and the positioning hole 11 passes through the base 1, so that the reagent kit 7 can be placed in the positioning hole 11 and the reagent kit 7 can be positioned by the groove wall of the positioning hole 11; the connecting component 2 is provided on the base 1, the supporting member 3 is provided on the connecting component 2, and the supporting member 3 is spaced apart from the base 1; one end of the elastic member 4 is provided on the supporting member 3, and the adsorption platform 5 is provided on the other end of the elastic member 4, so that the adsorption platform 5 is supported by the elastic member 4 to extend into the positioning hole 11; the adsorption platform 5 is used for vacuum adsorption of the reagent kit 7 placed in the positioning hole 11, so as to fix the reagent kit 7 on the adsorption platform 5; when the external heat sealing plate moves toward the base 1 to heat seal the reagent kit 7, the reagent kit 7 will be subjected to the pressure of the heat sealing plate, and at this time, the reagent kit 7 will compress the elastic member 4 to balance the pressure on the reagent kit 7 through the elastic member 4, thereby improving the stability of the force applied to the reagent kit 7.

[0045] In one embodiment, if Figure 1 , Figure 2 and Figure 4As shown, the adsorption platform 5 includes a seat body portion 51 and an adsorption portion 52. The seat body portion 51 is arranged at one end of the elastic member 4 away from the support member 3. A limiting hole 12 is also arranged on the base 1, and the limiting hole 12 is connected with the positioning hole 11. The orthographic projection of the contour of the positioning hole 11 on the plane where the base 1 is located is located within the orthographic projection of the contour of the limiting hole 12 on the plane where the base 1 is located and the orthographic projection of the seat body portion 51 on the plane where the base 1 is located, and the seat body portion 51 extends into the limiting hole 12. The adsorption portion 52 is arranged at one end of the seat body portion 51 away from the elastic member 4, and the adsorption portion 52 is opposite to the positioning hole 11, and the adsorption portion 52 can extend into the positioning hole 11.

[0046] The seat body 51 extends into the limiting hole 12, so that the groove wall of the limiting hole 12 can guide the seat body 51 to move along the extension direction of the elastic member 4, thereby preventing the seat body 51 from tilting when moving along the extension direction of the elastic member 4. The seat body 51 can also be limited by the groove wall of the limiting hole 12, thereby preventing the seat body 51 from being separated from the limiting hole 12.

[0047] The orthographic projection of the contour of the positioning hole 11 on the plane where the base 1 is located is located within the orthographic projection of the contour of the limiting hole 12 on the plane where the base 1 is located and the orthographic projection of the seat body 51 on the plane where the base 1 is located, so that the seat body 51 can extend into the limiting hole 12 but cannot extend into the positioning hole 11, thereby limiting the position of the seat body 51.

[0048] The adsorption portion 52 faces the positioning hole 11 and can extend into the positioning hole 11 , so that the adsorption portion 52 adsorbs the reagent kit 7 placed in the positioning hole 11 by vacuuming, thereby fixing the reagent kit 7 through the adsorption portion 52 .

[0049] In one embodiment, if Figures 1 to 3 As shown, the notch at one end of the positioning hole 11 away from the limiting hole 12 gradually increases in size in the direction away from the limiting hole 12, so that the inner wall of the notch at one end of the positioning hole 11 away from the limiting hole 12 is inclined. When the reagent box 7 is placed in the positioning hole 11, since the inner wall of the notch of the positioning hole 11 is inclined, the reagent box 7 can be guided by the notch of the positioning hole 11, so that the reagent box 7 slides into the positioning hole 11, thereby improving the efficiency of placing the reagent box 7 in the positioning hole 11.

[0050] In one embodiment, if Figure 1 and Figure 3 As shown, the base 1 is also provided with a tail groove 13, and the end of the tail groove 13 is connected to the positioning hole 11. The tail groove 13 is used to place the heat-sealing film 8, so as to facilitate the external heat-sealing plate to heat-seal the heat-sealing film 8 to the reagent box 7. Avoid the height difference between the heat-sealing film 8 and the reagent box 7, which affects the heat sealing of the reagent box 7.

[0051] In one embodiment, if Figure 1 and Figure 3As shown, the base 1 is also provided with an air blowing port 14, which is located in the tail groove 13. After the heat sealing film 8 is heat-sealed to the reagent box 7, air is inflated into the air blowing port 14 to blow up the heat sealing film 8 placed in the tail groove 13, so as to facilitate the subsequent folding of the heat sealing film 8.

[0052] In one embodiment, if Figure 1 and Figure 4 As shown, the profile of the adsorption portion 52 is an imitation shape, that is, the profile of the adsorption portion 52 is the same as the cross-sectional shape of the reagent box 7, thereby improving the stability of the adsorption portion 52 adsorbing the reagent box 7 to fix the reagent box 7 to the adsorption portion 52.

[0053] In one embodiment, if Figure 1 As shown, the fixing device further includes an adjusting member 6, which is disposed on the connecting assembly 2 and is used to adjust the distance between the supporting member 3 and the base 1. The distance between the supporting member 3 and the base 1 is adjusted by the adjusting member 6, so as to adjust the distance of the elastic member 4 relative to the base 1. The depth of the adsorption platform 5 extending into the positioning hole 11 is further adjusted by the elastic member 4, so as to further improve the stability of the force applied to the reagent box 7 and balance the force applied to the reagent box 7, so as to avoid crushing the reagent box 7.

[0054] In one embodiment, if Figure 1 As shown, the connection assembly 2 includes a guide rod 21 and a stopper 22. One end of the guide rod 21 is arranged on the base 1, and the guide rod 21 is penetrated by the support member 3, and the support member 3 can slide along the axial direction of the guide rod 21. The stopper 22 is arranged at the other end of the guide rod 21, and the adjustment member 6 penetrates the stopper 22, and the adjustment member 6 is threadedly connected to the stopper 22.

[0055] One end of the guide rod 21 is disposed on the base 1, and the other end is provided with a limiter 22, and the guide rod 21 is passed through the support member 3, so that the support member 3 is located between the base 1 and the limiter 22. Since the adjusting member 6 is threadedly connected to the limiter 22, the length of the adjusting member 6 passing through the limiter 22 can be increased by rotating the adjusting member 6. If the length of the adjusting member 6 passing through the limiter 22 increases, the adjusting member 6 will push the support member 3 toward the base 1 to adjust the distance between the support member 3 and the base 1. The guide rod 21 is used to guide the moving direction of the support member 3 to improve the stability of the support member 3 approaching or moving away from the base 1.

[0056] In one embodiment, if Figure 1 As shown, there are multiple positioning holes 11, connecting components 2, supporting members 3, elastic members 4 and adsorption platforms 5. A reagent kit 7 can be placed in each positioning hole 11, so that the reagent kit 7 can be adsorbed by the adsorption platform 5, so that the fixing device can adsorb and fix multiple reagent kits 7, thereby improving the efficiency of filling the reagent kit 7.

[0057] In addition, an embodiment of the present application also provides a reagent filling device, which includes a fixing device. The specific structure of the fixing device refers to the above embodiment. Since the reagent filling device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments.

[0058] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
