DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] like Figures 1-5 As shown, the present invention includes a base 1, a winding reel 2 and a barrel 3, wherein the winding side plates 201 on both sides of the winding reel 2 are respectively rotatably connected with the base side plates 101 on both sides of the base 1, and as shown Figure 3 As shown, the winding disc side plate 201 on either side is rotatably connected to the base side plate 101 on the corresponding side through the clockwork box 3. The clockwork box 3 includes a transmission shaft 305, a transmission disc 304, a clockwork seat 303 and a clockwork spring 302. The clockwork seat 303 is fixed on the base side plate 101 on the corresponding side. A clockwork cavity 309 for accommodating the clockwork spring 302 is provided in the clockwork seat 303. The transmission shaft 305 passes through the winding disc side plate 201 and the base side plate 101 on the corresponding side in sequence and is then inserted into the clockwork cavity 309 in the clockwork seat 303. The mainspring 302 is wound around the transmission shaft 305, and one end of the mainspring 302 is fixedly connected to the inner wall of the mainspring cavity 309, and the other end is fixedly connected to the transmission shaft 305. The transmission shaft 305 is provided with a transmission disc 304 at the end away from the mainspring 302, and the transmission disc 304 is fixedly connected to the corresponding reel side plate 201. In this way, when the winding reel 2 rotates, the transmission shaft 305 is driven to rotate through the corresponding reel side plate 201, while the mainspring seat 303 remains stationary, thereby achieving pre-tightening of the mainspring 302. The mainspring 302 is a well-known technology in the art.

[0024] like Figure 1 and Figure 3 As shown, the spring seat 303 is provided with an oil filling end cover 301 on the side away from the corresponding base side plate 101, and the oil filling end cover 301 covers the spring cavity 309 to ensure that it forms a sealed cavity. The oil filling end cover 301 is provided with an oil filling port 310 for filling lubricating oil.

[0025] like Figure 3As shown, the mainspring seat 303 is provided with a connecting disc 308 on the side close to the reel side plate 201, the connecting disc 308 is provided in a limiting groove on the base side plate 101 and is sleeved on the transmission shaft 305, a supporting ring 306 is arranged between the connecting disc 308 and the transmission shaft 305, the connecting disc 308 is matched with the mainspring seat 303 in a stop opening mode, and a sealing ring 307 is arranged between the connecting disc 308 and the mainspring seat 303. The connecting disc 308 ensures that there is enough gap between the reel side plate 201 and the base side plate 101, thereby ensuring smooth rotation of the collection reel 2.

[0026] As shown in the drawings, Figure 3 In the embodiment, the transmission disc 304 is connected with the corresponding reel side plate 201 by bolts, and the transmission disc 304 is connected with the transmission shaft 305 by a key.

[0027] As shown in the drawings, Figure 2 The reel side plate 201 of the collection reel 2 on the side away from the mainspring box 3 is provided with a reel shaft sleeve 203 in the middle, the base 1 on the side away from the mainspring box 3 is provided with a pipe sleeve 103 in the middle, and the pipe sleeve 103 is sleeved on the reel shaft sleeve 203, so as to realize the rotary connection of the corresponding reel side plate 201 and base side plate 101. The reel side plates 201 on both sides of the collection reel 2 are connected by reel connecting columns 202, and as shown in the drawings, Figure 4 The sample suction tube 4 is arranged on each reel connecting column 202 along the circumferential direction. Figure 2 As shown in the drawings, the tail end of the sample suction tube 4 is stretched out of the reel shaft sleeve 203 and connected with related equipment. The pipe sleeve 103 and the reel shaft sleeve 203 are also provided with a connecting disc 308 structure to ensure that there is enough gap between the reel side plate 201 and the base side plate 101 on this side.

[0028] As shown in the drawings, Figures 1-2 In the embodiment, the base 1 is provided with a base bottom plate 102 at the lower end, and the base side plates 101 are vertically arranged on both sides of the base bottom plate 102, and the collection reel 2 is arranged between the two base side plates 101.

[0029] The working principle of the application is as follows:

[0030] When the application is used, the winding reel 2 is rotated to rotate the transmission shaft 305 in the clockwork box 3, and the clockwork seat 303 in the clockwork box 3 is not moved, so that the clockwork 302 in the clockwork cavity 309 is pre-tightened. The operator can observe whether the clockwork 302 reaches the pre-tightening position by disassembling the oil injection end cover 301. When the clockwork 302 reaches the pre-tightening position, the operator passes the sample suction pipe 4 through the reel shaft sleeve 203 and out through the gap between any two reel connecting columns 202, and then winds the sample suction pipe 4 on the reel connecting columns 202 in the circumferential direction layer by layer. When the sample is sucked, the operator pulls out the sample suction pipe 4, and the sample suction pipe 4 rotates the winding reel 2 during the pulling-out process until the sample suction pipe 4 reaches the working length. After the work is completed, the operator releases the sample suction pipe 4, and the winding reel 2 automatically rotates to the original state under the action of the clockwork 302, and rotates and winds the sample suction pipe 4. The clockwork cavity 309 keeps the oil-filled state during the work to improve the corrosion resistance and service life of the clockwork 302.
