Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to fig. 1 to 4, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

Referring to fig. 1 to 4, the cervical sampler of the present embodiment includes an insertion tube 1 and a power component 2, a sampling component 3 is disposed in an inner cavity formed by the insertion tube 1 and the power component 2, the sampling component 3 includes a sampling rod 31, a first end of the sampling rod 31 is connected to the power component 2, a second end of the sampling rod 31 is connected to a sampling head 32, the insertion tube 1 has an opening 11 communicating with the outside and the inner cavity for the sampling head 32 to reciprocally extend and retract between the inner cavity and the outside; the power part 2 comprises a sleeve 21 with a through hole 211 and a rotary part 22, the inner wall of the sleeve 21 is provided with a thread groove 212, the rotary part 22 comprises a hollow inner sleeve 221 with an inner hole 224 and a rotary part 222 connected with the hollow inner sleeve 221, and the side surface of the hollow inner sleeve 221 is provided with a clamping groove 223 which is arranged along the axial direction and penetrates through the free end of the hollow inner sleeve 221; the hollow inner sleeve 221 is rotatably sleeved in the through hole 211, the first end of the sampling rod 31 is sleeved in the inner hole 224, and the protrusion 311 arranged at the first end of the sampling rod 31 is clamped in the clamping groove 223 and extends into the threaded groove 212; when the rotating portion 222 rotates, the protrusion 311 can rotate along the thread groove 212 and slide along the locking groove 223 to achieve the reciprocating extension and contraction of the sampling head 32 between the inner cavity and the outside.

Preferably, in this embodiment, the sidewall of the through hole 211 has a spiral ridge having a square cross section, and the spiral ridge forms the thread groove 212.

In this embodiment, the sampling rod 31 is rotated by the hollow inner tube 221 and the rotating portion 222, and also moves in the axial direction. The sampling rod 31 performs reciprocating telescopic movement in the opening 11 during the movement. In the case where the sampling rod 31 and the sampling head 33 are accommodated in the inner cavity of the insertion tube 1, the sampling rod 31 is rotated while rotating the rotating portion 222 when necessary and lifted upward in the axial direction by the screw groove 212 during the rotation, so that the sampling head 33 is pushed out for sampling use. It should be understood that in this embodiment, since the protrusion 311 passes through the locking groove 223 and extends into the thread groove 212, the protrusion 311 is forced to spirally slide upwards or downwards along the thread groove 212 during the rotation of the hollow inner sleeve 221, and the protrusion 311 is fixedly connected with the sampling rod 31, so that the sampling rod 31 also rotates and moves upwards or downwards in the axial direction when the protrusion 311 spirally slides. Meanwhile, it should be noted that in the present embodiment, after assembly, due to the limiting effect between the locking groove 223 and the protrusion 311, the sampling rod 31 and the rotating member 22 rotate synchronously, and the axial movement of the sampling rod 31 is driven during the rotation.

In addition, it should be understood that, during assembly, the hollow inner sleeve 221 of the rotary piece 22 is inserted into the through hole 211 of the sleeve 21, then the protrusion 311 of the sampling rod 31 is inserted into the inner hole 224 of the hollow inner sleeve 221 opposite to the slot 223 of the hollow inner sleeve 221 and rotated by a certain angle, so that the assembly of the rotary piece 22 and the sleeve 21 can be realized, and finally the sleeve 21 is connected with the insertion tube 1. The technical structure is relatively simple, the assembly and disassembly are very convenient, and the production and the use are convenient.

Referring to fig. 4, the end of the through hole 211 has a convex ring 213, the circumference of the root of the hollow inner sleeve 221 has a groove 225, the convex ring 213 is clamped in the groove 225 when the hollow inner sleeve 221 is sleeved on the through hole 211, and the convex ring 213 can rotate along the groove 225. By this technique a rotational connection of the hollow inner sleeve 221 and the rotary piece 22 is achieved. Wherein the outer diameter of the hollow inner sleeve 221 is larger than the inner diameter of the convex ring 213. When the hollow inner sleeve 221 is assembled, the hollow inner sleeve 221 is inserted into the through hole 211 of the sleeve 21 through the convex ring 213, the hollow inner sleeve 221 is elastically deformed during the insertion process until the elastic deformation is recovered after the convex ring 213 is matched with the groove 225, and then the hollow inner sleeve 221 is stably matched with the sleeve 21.

In order to ensure the stability of the sampling rod 31 during the spiral movement, the sampling rod 31 has a slip ring 312 on the periphery, and the slip ring 312 is in sliding contact with the inner cavity side wall of the insertion tube 1. I.e. the slide ring 312 slides along the inner lumen of the insertion tube 1 simultaneously as the sampling rod 31 moves in the axial direction, maintaining the stability of the sampling rod 31 in the radial direction.

In this embodiment, the insertion tube 1 and the sleeve 21 are connected by plugging. Specifically, the sleeve 21 is inserted into the inner cavity of the insertion tube 1. By adopting the technical scheme, the insertion tube 1 and the sleeve 21 can be conveniently matched and connected, and convenient disassembly and assembly are realized. Meanwhile, in order to ensure that the insertion pipe 1 is cracked at the position where the insertion pipe is inserted and matched with the sleeve 21 in the repeated insertion process, the peripheral side of the insertion pipe 1 close to the part inserted and matched with the sleeve 21 is provided with an annular holding part 12. The thickness of the insertion tube 1 and the sleeve 21 is actually increased by the annular holding portion 12, which serves as a reinforcement. In order to better grip the annular grip portion 12 and prevent slipping, the annular grip portion 12 has a first protrusion provided on the circumferential side thereof in the axial direction.

Similarly, in order to prevent the hand from slipping when the rotating portion 222 is rotated, the circumferential side of the rotating portion 222 has a second protrusion disposed along the axial direction.

It should be understood that the hollow inner bushing 221 and the rotating portion 222 are an integral structure in this embodiment. It is made of elastic plastic. Of course, in addition to this, the hollow inner sleeve 221 and the rotary part 222 may also be of a split design.

In a word, the technical scheme of the utility model simple structure, convenient operation, the dismouting is also convenient moreover, can satisfy production and user demand.

Variations and modifications to the above-described embodiments may occur to those skilled in the art, in light of the above teachings and teachings. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
