Detailed Description

The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

The utility model provides a powder sampler, as shown in fig. 1-5, including sampler barrel 1, 1 lower extreme fixedly connected with grab handle 2 of sampler barrel is equipped with the sample structure in the sampler barrel 1, the sample structure is including dwang 6, dwang 6 one end is connected with handle 5, and the other end of dwang 6 is equipped with fixed axle 12, and the front end fixedly connected with sampling spoon 9 of fixed axle 12, the middle-end fixedly connected with cam 7 of dwang 6, 1 inner wall of sampler barrel are equipped with the driving column 8 with cam 7's inside groove sliding connection, 1 lower extreme of sampler barrel is equipped with and connects appearance box 3 corresponding with sampling spoon 9, and the bottom that connects appearance box 3 is equipped with hourglass material hole 11.

When the utility model is used, one end of the sampling tube 1 is close to the powder, the grab handle 2 is held by one hand, the handle 5 is pushed by the other hand, the handle 5 drives the rotating rod 6 to move forwards, the rotating rod 6 synchronously drives the cam 7 and the sampling spoon 9 to move forwards, in the process that the cam 7 moves forwards, the inner groove of the cam 7 is meshed with the driving column 8, under the limit of the driving column 8, the cam 7 rotates in the process of moving forwards, the cam 7 drives the rotating rod 6 to rotate in turn, in the process that the rotating rod 6 drives the sampling spoon 9 to push forwards, because the opening of the sampling spoon 9 in the initial state is downward, the pushing distance of the handle 5 just meets the requirement that the sampling spoon 9 rotates 90 degrees, at the moment, the opening of the sampling spoon 9 is upward, because the cam 7 is provided with a straight groove connected with a curved groove, the sampling spoon 9 always keeps sliding forward with the opening upward, the sampling spoon 9 is used for sampling the powder, after the sample is accomplished, loosen handle 5, because the straight flute and the 12 meshes mutually of fixed axle of cam 7, consequently in sample spoon 9 keeps mouthful getting into sampling tube 1 up, the groove of cranking of cam 7 and the 12 meshes mutually of fixed axle this moment, cam 7 rotates and drives sample spoon 9 and rotates 90 degrees, and the mouth of sample spoon 9 is at this moment down completely, pours the powder into all in connecing appearance box 3, by the hourglass material hole 11 entering sampling bottle of connecing appearance box 3.

As shown in figures 1 and 2, one end of the sampling tube 1 is provided with a limiting column 10 which is rotatably connected with the rotating rod 6, and a return spring 4 which is sleeved and connected with the rotating rod 6 is arranged between the limiting column 10 and the handle 5.

Preferably, in the process that the rotating rod 6 slides forwards while rotating, the limiting column 10 plays a role in limiting and supporting the rotating rod 6, and on the other hand, the resetting spring 4 plays a role in blocking, so that the resetting spring 4 can be normally compressed, and the resetting spring 4 plays a role in resetting the rotation of the sampling spoon 9.

As shown in fig. 2 and 4, one end of the rotating rod 6 is fixedly connected with a sliding column 14, and the sliding column 14 is rotatably connected with the inner wall of the handle 5.

Preferably, when the handle 5 is pushed forward, the function of the sliding column 14 is to ensure that the handle 5 can be pushed forward normally without affecting the rotation of the rotating rod 6, because the rotating rod 6 needs to be rotated.

As shown in figure 2, the inner wall of the front end of the sampling tube 1 is provided with a baffle 13 matched with the sampling spoon 9, and the inner wall of the baffle 13 is rotatably connected with the rotating rod 6.

Preferably, baffle 13 plays spacing effect to sampling spoon 9, prevents that sampling spoon 9 from leading to sampling spoon 9 too much to remove to the rear end of sampler barrel 1 because reset spring 4's restoring force effect for the powder can't accurately fall into in connecing appearance box 3, and can also block the powder of powder and volatilize to the rear end of sampler barrel 1, influence life.

As shown in fig. 1 and 2, the handle 2 is provided with a plurality of anti-slip grooves.

Preferably, the anti-skid groove plays a role in anti-skid and wear-resistant for the hand.

The utility model discloses a working process does: when the utility model is used, one end of the sampling tube 1 is close to the powder, the grab handle 2 is held by one hand, the handle 5 is pushed by the other hand, the handle 5 drives the push rod to move forwards, the push rod synchronously drives the cam 7 and the sampling spoon 9 to move forwards, in the forward movement process of the cam 7, the inner groove of the cam 7 is meshed with the driving column 8, under the limit of the driving column 8, the cam 7 rotates in the forward movement process, the cam 7 drives the rotating rod 6 to rotate in reverse, the rotating rod 6 drives the sampling spoon 9 to rotate in the forward movement process, because the opening of the sampling spoon 9 is downward in the initial state, the distance which can be pushed by the handle 5 just meets the requirement that the sampling spoon 9 rotates 90 degrees, at the moment, the opening of the sampling spoon 9 is upward, because the straight groove connected with the curved groove is arranged on the cam 7, the sampling spoon 9 always keeps the opening sliding forward upward, the sampling spoon 9 is used for sampling the powder, after the sample is accomplished, loosen handle 5, because the straight flute and the 12 meshes mutually of fixed axle of cam 7, consequently in sample spoon 9 keeps mouthful getting into sampling tube 1 up, the groove of cranking of cam 7 and the 12 meshes mutually of fixed axle this moment, cam 7 rotates and drives sample spoon 9 and rotates 90 degrees, and the mouth of sample spoon 9 is at this moment down completely, pours the powder into all in connecing appearance box 3, by the hourglass material hole 11 entering sampling bottle of connecing appearance box 3.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or scope of the invention as defined in the appended claims.
