Specific embodiments

[0024] The following further describes the present utility model through specific embodiments.

[0025] Referring to Figures 1 to 6 As shown, a blood collection specimen conveying device applicable to a limited space includes a conveying frame 1, a rotating gear 2 rotatably arranged on one side of the conveying frame 1, a driven gear 3 oppositely arranged with the rotating gear 2 on the other side of the conveying frame 1, a conveying toothed belt 4 tensioned between the rotating gear 2 and the driven gear 3, a rotating motor 5 arranged on the conveying frame 1 to connect and drive the rotation of the rotating gear 2, and an adjusting mechanism 6 arranged in the conveying frame 1 to connect with the driven gear 3 and adjust the tension of the conveying toothed belt 4.

[0026] The conveying rack 1 includes two oppositely arranged vertical plates 11, an upper receiving plate 12 and a lower receiving plate 13 which are arranged oppositely up and down between the two vertical plates 11, a support frame 14 arranged between the upper receiving plate 1 and the lower receiving plate 13, and two mounting blocks 15 arranged oppositely at both ends of the two vertical plates 11. The arrangement of the support frame 14 can ensure the overall strength of the conveying rack 1, making the conveying device not easily bend and deform. Among them, an installation area 16 for installing the adjusting mechanism 6 is formed between the end of the support frame 14 and the driven gear 3, and an operation hole 17 opposite to the installation area 16 is arranged on the vertical plate 11. Through the operation hole 17, the operation of the adjusting mechanism 6 can be controlled from the outside, realizing the adjustment of the tension of the conveying tooth belt 4. The overall operation is simple and easy to implement. Specifically, the connection between the vertical plate 11 and the mounting block 15 is detachable. The mounting block 15 is formed with two mounting grooves 18 extending downward from its top surface for the two vertical plates 11 to be embedded respectively. The vertical plate 11 is installed in the mounting groove 18 through a bolt assembly. By defining that the two vertical plates 11 are detachably arranged on the two mounting blocks 15, when the conveying device fails, the vertical plate 11 can be removed to repair the conveying device without removing the whole machine.

[0027] The upper receiving plate 12 is provided with an upper positioning groove 121 extending downward from its top surface, and the lower receiving plate 13 is provided with a lower positioning groove 131 extending upward from its bottom surface. The conveying tooth belt 4 is wound around the upper positioning groove 121 and the lower positioning groove 131. The settings of the upper positioning groove 121 and the lower positioning groove 131 can play a role in correcting the deviation of the conveying tooth belt 4 and ensure the stable operation of the conveying tooth belt 4. Specifically, the upper receiving plate 12 is further provided with two guiding and correcting surfaces 122 extending obliquely inward downward from its top surface and communicating with the upper positioning groove 121. Through the settings of the two guiding and correcting surfaces 122, it plays a guiding role for the blood collection specimen to ensure that the blood collection specimen smoothly enters the conveying tooth belt 4.

[0028] The adjusting mechanism 6 includes a fixed block 61 arranged on the top of the lower receiving plate 13, an adjusting plate 62 that can move back and forth relative to the fixed block 61 and is connected to the driven gear 3, and an adjusting member 63 arranged on the fixed block 61 and connected to the adjusting plate 62. Among them, the vertical plate 11 is provided with a moving hole 19 extending along the moving direction of the adjusting plate 62, and both ends of the driven gear 3 are respectively supported between two opposite moving holes 19.

[0029] The driven gear 3 includes a rotating shaft 31 supported between the two moving holes 19 and a driven gear body 32 rotatably arranged on the rotating shaft 31. Among them, the rotating shaft 31 includes a rotating rod 33 and two non-circular support blocks 34 oppositely arranged at both ends of the rotating rod 33 and respectively supported in the two moving holes 19. By arranging the non-circular support blocks 34 that can be supported in the moving holes 19 at both ends of the rotating rod 33, the rotating shaft 31 can move back and forth in the moving holes 19 under the action of the adjusting mechanism 6 but will not rotate with the driven gear body 32, ensuring the normal operation of the driven gear 3.

[0030] The fixed block 61 includes a fixed block body 611 provided on the top of the lower bearing plate 13, and two guiding parts 612 oppositely arranged up and down on the opposite surfaces of the fixed block body 611 and the adjusting plate 62. Two guiding grooves 624 for the two guiding parts 612 to be respectively embedded are formed on the adjusting plate 62. Through the mutual cooperation of the guiding parts 612 and the guiding grooves 624, the adjusting plate 62 can move smoothly back and forth relative to the fixed block 61, so that the tension of the conveying toothed belt 4 can be adjusted without stopping the machine.

[0031] The adjusting plate 62 includes an adjusting plate body 621 opposite to the fixed block 61 and two connecting plate bodies 622 oppositely arranged on both sides of the adjusting plate body 621 and respectively connected to the two ends of the rotating rod 33. Wherein, a connecting groove 623 for the end of the rotating rod 33 to be embedded is formed by the inward extension of the opposite surfaces of the connecting plate body 622 and the rotating rod 33.

[0032] The adjusting member 63 includes an adjusting screw hole 631 provided in the fixed block 61, an adjusting screw 632 matched with the adjusting screw hole 631, and an adjusting nut 633 provided on the adjusting screw 632. Wherein, the front end of the adjusting screw 632 is connected to the adjusting plate 62, and the operation hole 17 is opposite to the adjusting screw 632. During operation, the adjusting screw 632 can be operated through the operation hole 17 to cooperate with the adjusting nut 633 to adjust the tension of the conveying toothed belt 4 to meet the conveying requirements of blood collection specimens. After the adjusting screw 632 completes the adjustment of the tension of the conveying toothed belt, the adjusting nut 633 can be locked and abutted against the fixed block 61 to prevent the adjusting screw 632 from loosening during long-term use, effectively ensuring the reliability of the conveying device.

[0033] By defining the structure of the conveying frame 1, the present application arranges the adjusting mechanism 6 for adjusting the conveying toothed belt 4 inside the conveying frame 1, avoiding interference with other structures, with a beautiful overall structure, being conducive to modular design, convenient for replacement during later maintenance and repair, reducing the working hours and difficulty of equipment maintenance, being applicable to limited or narrow space environments, being able to maximize the use of the existing space, and ensuring the effective transmission of blood collection specimens without increasing additional floor area.

[0034] The above is only a preferred embodiment of the present utility model, and thus cannot limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the content of the specification should still fall within the scope covered by the patent of the present utility model.
