[0015] Compared with the prior art, the present invention provides a medical detection sampling device, which has the following beneficial effects: 1.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example 1: See Figure 1-Figure 4 , Figure 7 The present invention provides a technical solution: a medical detection sampling device, comprising a sampling mechanism 1, the sampling mechanism 1 comprises a sampler 101, a fixing ring 102 is fixedly sleeved on the bottom outer surface of the sampler 101, a first connecting shaft 103 is fixedly connected to the bottom outer wall of the fixing ring 102, an auxiliary mechanism 3 is arranged at the bottom of the fixing ring 102, a groove 119 is provided on the bottom outer surface of the sampler 101, a sampling probe 120 is arranged on the side of the sampler 101 close to the groove 119, a second connecting shaft 108 is fixedly connected to the top outer wall of the sampler 101, a visual scale 104 is provided on the outer surface of the sampler 101, a first fixing shaft 105 is fixedly connected to the inner wall of the sampler 101, a first fixing rod 107 is fixedly connected to the outer surface of the sampler 101, a sliding groove 109 is provided on the outer surface of the sampler 101, and also comprises: The adjusting mechanism 2 comprises a second sliding frame 201 which is slidably connected to the inner wall of the sampler 101, a force block 202 is arranged on the outer wall of the second sliding frame 201, an outer wall of the force block 202 on one side close to the second sliding frame 201 is fixedly connected to a third connecting shaft 203, an outer wall of the third connecting shaft 203 on one end away from the force block 202 is fixedly connected to a sliding block 204, an outer wall of the force block 202 on one side close to the second sliding frame 201 is fixedly connected to a second spring 206, an end of the second spring 206 away from the force block 202 is fixedly connected to the second sliding frame 201, and the inner wall of the sliding block 204 is connected to the second sliding frame 201 by a rotating shaft. The flip rod 205 is rotatably connected. When the height of the second sliding frame 201 needs to be adjusted, the force block 202 will push the sliding block 204 toward the sampler 101 with the help of the third connecting shaft 203. During this process, the pushing action of the force block 202 causes it to produce an extrusion effect on the second spring 206. At the same time, the sliding block 204 will drive one end of the flip rod 205 to flip toward the side of the sampler 101 through the rotating shaft, thereby allowing the second sliding frame 201 to slide along the outer surface of the first fixed shaft 105, and finally achieving the adjustment of the height of the second sliding frame 201.

[0025] The inner wall of the sampler 101 is slidably connected to a piston 116, and the top outer wall of the piston 116 is fixedly connected to a second fixing rod 113. The end of the second fixing rod 113 away from the piston 116 passes through the sampler 101 and is fixedly connected to a pressure rod 111. The piston 116 fits tightly with the inner wall of the sampler 101 during the pushing process. When performing the sampling operation, the sampling probe 120 is first placed in the liquid to be sampled, and then the pressure rod 111 is pulled to cause the piston 116 to slide on the inner wall of the sampler 101, thereby creating a negative pressure environment at the end of the sampler 101 adjacent to the sampling probe 120, and then the liquid is sucked into the sampler 101 to complete the sampling operation.

[0026] The top outer surface of the pressure rod 111 is provided with a water injection port 112, the outer surface of the second fixed rod 113 is provided with a through hole 114, the outer wall of the pressure rod 111 close to the second fixed rod 113 is fixedly connected with a second fixed shaft 115, the outer wall of the second fixed shaft 115 away from the pressure rod 111 is fixedly connected with a sliding ring 121, the inner wall of the sliding ring 121 is slidably connected with the outer surface of the first fixed shaft 105, the second fixed shaft 115 is used to improve the stability of the pressure rod 111 during movement, the sliding ring 121 and the piston 116 are at the same height, when the need to clean the inside of the sampler 101 is faced, the cleaning liquid needs to be introduced into the internal space of the sampler 101 through the water injection port 112. In this process, the cleaning liquid will be ejected outward from the inside of the second fixed rod 113 through the through hole 114, and with the help of this ejection effect, the inside of the sampler 101 is fully flushed to achieve the purpose of cleaning its inside.

[0027] The inner wall of the sampler 101 is provided with a first drainage hole 106, the top outer surface of the sampler 101 is provided with a second drainage hole 110, the top of the sampler 101 is provided with a first sliding frame 117, the inner wall of the first sliding frame 117 away from the sampler 101 is slidably connected to the second connecting shaft 108, the outer wall of the first sliding frame 117 close to the sampler 101 is fixedly connected to the first spring 118, the end of the first spring 118 away from the first sliding frame 117 is fixedly connected to the sampler 101, and when the sampler 101 is closed, the sampler 101 is opened. When the sampler 101 is flushed, the sampler 101 is first placed upside down. At this time, the first sliding frame 117 slides toward the pressure rod 111 under the action of gravity. This process creates an extrusion effect on the first spring 118, and the cleaning liquid used in the flushing process is smoothly discharged through the pre-set first drain hole 106 and second drain hole 110, thereby completing the flushing and drainage operation of the sampler 101 and ensuring that the inside of the sampler 101 can be effectively cleaned.

[0028] The auxiliary mechanism 3 includes a force-bearing plate 301 slidably connected to the first connecting shaft 103, the top outer wall of the force-bearing plate 301 is fixedly connected to a third spring 302, one end of the third spring 302 away from the force-bearing plate 301 is fixedly connected to the fixing ring 102, the third spring 302 is used for resetting the force-bearing plate 301, the first connecting shaft 103 is used to improve the stability of the force-bearing plate 301 during movement, the inner wall of the force-bearing plate 301 is rotatably connected to a rotating rod 303 through a rotating shaft, and the inner wall of the end of the rotating rod 303 away from the force-bearing plate 301 is rotatably connected to an auxiliary block 304 through a rotating shaft. When the head 120 needs to be replaced, the force plate 301 needs to be pressed, and the force plate 301 will move toward the side where the sampler 101 is located along the direction of the first connecting shaft 103. In the process of the force plate 301 gradually approaching the sampler 101, the third spring 302 will be squeezed. At the same time, the force plate 301, with the help of the linkage effect of the rotating rod 303, pushes the auxiliary block 304 to slide on the inner wall of the groove 119 in the direction close to the first connecting shaft 103, thereby releasing the restriction state of the auxiliary block 304 on the sampling probe 120, so as to successfully complete the replacement operation of the sampling probe 120.

[0029] Example 2: Please refer to Figure 5-Figure 6 , Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: the inner wall of one end of the flip rod 205 away from the sliding block 204 is slidably connected to the outer surface of the first fixed shaft 105, the bottom outer wall of the second sliding frame 201 is fixedly connected with an elastic component 207, and the outer wall of the second sliding frame 201 close to the visual scale 104 is fixedly connected with a cross bar 208, and the elastic component 207 is used to limit the sliding height of the sliding ring 121. When the flip rod 205 contacts the outer surface of the sampler 101, the movement of the second sliding frame 201 will be restricted and stopped. After the position of the second sliding frame 201 is fixed, the cross bar 208 can assist the operator to read the value displayed by the visual scale 104 more accurately.
