DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. In the following description, a large number of specific details are set forth in order to give a sufficient understanding of the utility model, but the utility model can also be implemented in other manners different from those described herein, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0023] Please refer to Figures 1 to 4 As shown in the drawings, a portable inspection device comprises a cylinder 1, a liquid inlet pipe 2, a piston 3, two fixed plates 4 and a clamping part 5. The cylinder 1 is a hollow circular cylinder for accommodating a sample to be detected. The liquid inlet pipe 2 is connected to one end of the cylinder 1. The piston 3 is slidingly arranged inside the cylinder 1. One end of the piston 3 extends away from the cylinder 1 through the other end of the cylinder 1. In this embodiment, the piston 3 comprises a plug head 31 and a plug rod 32. The plug head 31 is slidingly connected to the inner wall of the cylinder 1. The plug rod 32 is fixedly arranged at the end of the plug head 31 away from the liquid inlet pipe 2. During implementation, the plug rod 32 of the piston 3 is pulled to generate negative pressure in the cylinder 1, so that the sample is drawn into the cylinder 1 from the liquid inlet pipe 2.

[0024] In this embodiment, a plurality of clamping grooves 3221 are recessed on the side wall of the plug rod 32. The plurality of clamping grooves 3221 are uniformly arranged along the axial direction of the plug rod 32. Specifically, the plug rod 32 comprises a fixed column 321 and a plurality of support plates 322 fixedly arranged on the outer side of the fixed column 321. The plurality of support plates 322 are uniformly arranged along the circumferential direction of the fixed column 321. The plurality of clamping grooves 3221 are arranged on the side of the plurality of support plates 322 away from the fixed column 321. The two fixed plates 4 are fixedly arranged at the end of the cylinder 1 away from the liquid inlet pipe 2. The two fixed plates 4 are respectively located on the two sides of the cylinder 1 in the radial direction. The clamping part 5 is one or two. At least one clamping part is slidingly arranged in the fixed plate 4 and used for clamping with the clamping grooves 3221.

[0025] Specifically, the clamping part 5 comprises a sliding block 51, the fixed plate 4 is provided with a through groove 41 communicated with the inside of the barrel 1, and the sliding block 51 is slidingly arranged in the through groove 41. When it is needed to position the plug rod 32, one end of the sliding block 51 extends to the inside of the barrel 1 through the through groove 41 and is clamped with the clamping groove 3221. In this way, the piston 3 cannot slide along the axial direction of the barrel 1, thereby avoiding that the plug rod 32 is extruded by external force in the process of moving the barrel 1, so as to cause the sample in the barrel 1 to leak and cause damage to the sample and cause bacteria to spread.

[0026] As shown in Figures 2 to 4 the sliding block 51 comprises a clamping block 511 close to one side of the barrel 1 and a pressing block 512 away from one side of the barrel 1, the thickness of the clamping block 511 is smaller than the thickness of the pressing block 512, and the clamping block 511 is located on one side of the pressing block 512. The end of the through groove 41 close to the barrel 1 is matched with the clamping block 511, that is, the opening of the end of the through groove 41 close to the barrel 1 is matched with the shape of the clamping block 511. In this way, the clamping block 511 can extend to the inside of the barrel 1 through the through groove 41. The inside of the through groove 41 is provided with a first spring 6, and the first spring 6 is located on one side of the clamping block 511. The two ends of the first spring 6 respectively abut against the pressing block 512 and the side wall of the fixed plate 4 close to the barrel 1, so as to prevent the sliding block 51 from moving towards the barrel 1, thereby avoiding that the sliding block 51 is accidentally clamped with the clamping groove 3221, causing the plug rod 32 to be limited in movement when the sample is drawn.

[0027] Preferably, the fixed plate 4 on both sides of the width direction of the through groove 41 is respectively provided with a positioning block 411, and the sliding block 51 on both sides of the width direction is respectively provided with a sliding groove 513 matched with the positioning block 411. In the implementation process, the sliding block 51 is prevented from being separated from the through groove 41 through the sliding connection of the positioning block 411 and the sliding groove 513, that is, the sliding block 51 is prevented from sliding out of the through groove 41 due to the abutment of the first spring 6.

[0028] The side of the fixed plate 4 close to the liquid inlet pipe 2 is provided with a stop component 7 for limiting the clamping part 5 from sliding away from the barrel 1. In the embodiment, the stop component 7 comprises a rotating plate 71 rotatably arranged on the outer side wall of the fixed plate 4, and a positioning column 72 fixedly arranged on one end of the rotating plate 71. The free end of the positioning column 72 extends to the inside of the through groove 41 through the side wall of the fixed plate 4. The side of the sliding block 51 close to the stop component 7 is recessed with a positioning groove 541. When the clamping block 511 is clamped with the clamping groove 3221, the positioning column 72 corresponds to and is clamped with the positioning groove 541. The other end of the rotating plate 71 is provided with an elastic part for pushing the positioning column 72 to rotate towards the direction close to the through groove 41.

[0029] In implementation, when the staff completes the sample extraction, the pressing block 512 of the sliding block 51 is pressed, and then the clamping block 511 is driven to move towards the direction close to the barrel 1 until the clamping block 511 is clamped in the corresponding clamping groove 3221, at this time, the piston 3 cannot move along the axial direction of the barrel 1, and at the same time, when the clamping block 511 is clamped in the corresponding clamping groove 3221, the positioning groove 541 moves to the position corresponding to the positioning column 72, and the positioning column 72 is always kept rotating towards the direction of the through groove 41 by the pushing of the elastic part, so that the positioning column 72 is clamped in the positioning groove 541 at the same time, thereby avoiding the clamping block 511 from being separated from the clamping groove 3221 due to the movement of the sliding block 51. By arranging the positioning column 72 and the positioning groove 541, the clamping between the clamping block 511 and the clamping groove 3221 is more stable, and the sample in the barrel 1 is prevented from leaking due to the extrusion of the plug rod 32, thereby preventing the damage of the sample and the spread of bacteria.

[0030] Preferably, the elastic part is a second spring 8, the second spring 8 is located between the rotating plate 71 and the fixed plate 4, and the two ends of the second spring 8 are respectively abutted with the other end of the rotating plate 71 and the fixed plate 4, so that the positioning column 72 is always kept rotating towards the direction of the through groove 41 by the elastic force of the second spring 8. When the barrel 1 moves to the preset position and the sample needs to be discharged, the staff needs to press the other end of the rotating plate 71, at this time, the second spring 8 is compressed, the positioning column 72 located at one end of the rotating plate 71 rotates away from the positioning groove 541 until the positioning column 72 is separated from the positioning groove 541, and then the sliding block 51 moves away from the barrel 1 by the elastic force of the first spring 6 until the clamping block 511 is separated from the clamping groove 3221, at this time, the staff can push the piston 3 to move towards the direction close to the liquid inlet pipe 2, so that the sample is discharged from the barrel 1 through the liquid inlet pipe 2.

[0031] In implementation, the staff pulls the piston 3 to suck the sample to be detected into the barrel 1 through the liquid inlet pipe 2, when the sample in the barrel 1 reaches the preset amount, the staff presses the sliding block 51 to move the sliding block 51 towards the barrel 1 until the clamping block 511 of the sliding block 51 is clamped in the corresponding clamping groove 3221, at this time, the positioning column 72 is clamped in the positioning groove 541 at the same time, so that the sliding block 51 cannot slide along the through groove 41, thereby fixing the piston 3, and preventing the sample in the barrel 1 from leaking due to the extrusion of the plug rod 32, thereby preventing the damage of the sample and the spread of bacteria. When the sample needs to be discharged, the staff presses the other end of the rotating plate 71, so that the positioning column 72 is not clamped in the positioning groove 541, and then the sliding block 51 is reset by the elasticity of the first spring 6. It should be noted that since the positioning block 411 and the sliding groove 513 are arranged, the sliding block 51 will not be separated from the through groove 41 when the first spring 6 is reset.

[0032] The above description is merely preferred embodiments of the present application, and obviously, the described embodiments are only a part but not all of the embodiments of the present application. Based upon the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall into the range of protection of the present application.
