SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the present invention is to provide a rapid sampling device for food detection, so as to solve the technical problems in the background art.

The technical scheme of the utility model is as follows:

the utility model provides a food detects quick sampling device, includes sampling needle and sample cover, and the sampling needle top is provided with the handle, along the sampling needle with the same one-side spaced apart a plurality of notches that are equipped with to homonymy one-to-one notch top all opens the sample window on the sample cover, the seal section width that the notch corresponds is greater than the sample window.

Furthermore, the circular arcs corresponding to the cross sections of the notch and the sampling window are smaller than a semicircle.

Further, sample cover both ends are the opening, and most advanced is established to the sample needle bottom, and sample cover bottom is provided with the oblique section of splitting with most advanced transition, is provided with the thrust collar that corresponds sample cover top at the sample needle root.

Furthermore, a positioning structure is arranged between the sampling sleeve and the sampling needle.

Further, location structure is including the snap ring that is located the handle bottom and articulate the buckle at sample cover top outer wall, and the bayonet socket is all seted up corresponding notch side and relative notch side to the snap ring, and the buckle articulates one side that corresponds sample window side or relative sample window through the hank seat, and the bayonet socket internal fixation can be gone into to the buckle.

The utility model has the advantages that:

when the packaged food, such as rice, wheat, flour and the like, is sampled, the sampling sleeve is sleeved on the sampling needle, the sampling window and the notch are staggered by rotating the sampling sleeve, then the sampling sleeve is inserted into a package or a container, the sampling sleeve is rotated until the sampling window corresponds to the notch, then the sampling sleeve is rapidly shaken up and down, at the moment, the samples enter the notch through the sampling window respectively to finish sample collection at different depths, then the samples are drawn out, the sampling device is horizontally placed above a paper surface, the notch of the sampling needle faces downwards, the sampling window faces upwards, the sampling sleeve is horizontally removed, and the samples fall onto the paper surface respectively. Can once only realize the sample collection of multilayer degree of depth, and insert or take out the in-process and can not take the sample of non-collection degree of depth, only need the closed section width that the notch corresponds to be greater than the sample window and can rotate the back and seal completely, in the actual operation the circular arc that notch and sample window cross section correspond all be less than the semicircle can.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1-4:

the utility model provides a food detects quick sampling device, includes sampling needle 1 and sample cover 4, and 1 top of sampling needle is provided with handle 2, along 1 same one side spaced apart of sampling needle be equipped with a plurality of notch 11 to sample window 41 has all been opened at 11 tops of homonymy one-to-one notch on sample cover 4, the closed section width that notch 11 corresponds is greater than sample window 41.

The working principle is as follows: to the food of packing, for example, the rice, the wheat, when the powder face etc. is sampled, establish 4 covers of sampling on sampling needle 1, rotatory sampling cover 4 makes sampling window 41 misplace with notch 11, later insert in packing or the container, rotatory sampling cover 4 corresponds with notch 11 to sampling window 41, then shake about rapidly, the sample is gathered through the sample of accomplishing the different degree of depth in sampling window 41 entering notch 11 respectively this moment, later take out, place the sampling device level in the paper top, notch 11 of sampling needle 1 is down, sampling window 41 is up this moment, sampling cover 4 is removed to the level, the sample will fall into on the paper respectively. The utility model can realize the sample collection of multilayer depth at one time, and can not bring the sample of non-collection depth in the process of inserting or extracting, the closed section corresponding to the notch 11 is wider than the sampling window 41, the sample can be completely closed after rotating, and the arcs corresponding to the cross sections of the notch 11 and the sampling window 41 are both smaller than a semicircle in the actual operation.
