Abstract

The utility model discloses a high road surface testing core sample storage box. An upper port and a lower port of a box body are respectively provided with a sealing cover which is screwed with a screw thread. The lower part of an upper cover is connected with a spring of which the lower end is connected with a movable piston. The high road surface testing core sample storage box is especially used for storing tools of a core sample and has simple principle. The utility model solves the problems of the storing of a core sample when the core is taken, prevents the core sample from being squeezed and impacted, and ensures the core sample from being damaged in the process of storing and transporting of the core sample.

Description

Highway pavement test core Storage Box

Technical field

The utility model relates to a kind of highway pavement test core Storage Box.

Background technology

Get in the process of core in the highway engineering test at present, be not specifically designed to the instrument of depositing the core that is taken out, the core of taking-up generally can only be packed very easily with plastic bag.Core often is squeezed and collides in this case, both has been unfavorable for storage, the transportation of core, also is unfavorable for the drying of core simultaneously, has influenced the actual effect of test.

The utility model content

The purpose of this utility model provides a kind of highway pavement test core Storage Box that can guarantee that core is not damaged in storage, transportation.The technical solution of the utility model is: a kind of core Storage Box, on the upper and lower port of box body, the capping that screw thread spins is housed respectively, and below loam cake, be associated with a spring, be associated with a mobile piston in the spring lower end.On the lower cover upper surface, be fixedly connected with a rotor.On the box body wall, breather hole is arranged.Have a pointer groove longitudinally on the wall of box body, be provided with scale in that the pointer groove is other, pointer connects firmly mutually with mobile piston.Last covering handle is housed.Top at the pointer groove is provided with active card.

The utility model has following advantage:

Highway pavement test core Storage Box is the instrument of depositing core that is specifically designed to, and its principle is simple, has solved the problem that core is deposited in the core process of getting, the protection core is avoided extrusion and collision, guaranteed core store, transport cross kind in be not damaged.Simultaneously, the breather hole on its sidewall can promote and help the drying of core; Mobile piston and spring can be regulated the length of box inner height, guarantee that the core of differing heights all can not shaken in box, can make the process of taking out core in the box simple and easy to do again; Pointer and scale can conveniently be measured the length of core exactly when storing; Movable card is distinguished different cores, the inconvenience of avoiding core to obscure causing.By these functions, the core Storage Box is protected the core that is taken out easily and effectively, thereby for engineering test facilitates, improves the efficient of test, the accuracy rate of warranty test.Storage Box itself use engineering plastics, have portable simple in structure, easy to use, durable, light, characteristics such as not fragile and with low cost, be fit to the needs that core is got in the highway engineering test.

Description of drawings

Fig. 1 is the utility model structural representation,

Fig. 2 is the utility model structure cut-away view.

Specific embodiment structure of the present utility model is as shown in Figure 1 and Figure 2:, a kind of core Storage Box, the

capping

2,10 that screw thread spins respectively is housed on the upper and lower port of box body, below loam cake 2, be associated with a spring 4, be associated with a mobile piston 6 in spring 4 lower ends.On lower cover 10 upper surfaces, be fixedly connected with a rotor 13.Breather hole 5 is arranged on the box body wall.Have a pointer groove 14 longitudinally on the wall of box body, be provided with scale 9 in that pointer groove 14 is other, pointer 8 connects firmly mutually with mobile piston 6.Handle 1 is housed on loam cake 2.Be provided with active card 3 on the top of pointer groove 14.The utility model constructional feature:

1, Storage Box integral body is cylindrical, and by loam cake 2 and lower cover 10 sealings, upper and lower covers all adopts spiral upper and lower side, covers the screw that is useful on spinner, and handle 1 is arranged on the loam cake 2 in addition, makes things convenient for carrying and transporting of Storage Box respectively.

2, the bottom of loam cake 2 connects spring 4, the spring bottom connects mobile piston 6, all fixing between spring and loam cake, spring and the mobile piston 6 with check screw 7, after depositing core in the box, can regulate the internal height of Storage Box according to the actual length of core by mobile piston 6 and spring 4, to prevent the core damage that upheaval is caused in box.

3, the lower cover upper end is fixed with lower cover rotor 13, and when tightening the upper and lower covers screw, rotor 13 can be close to core rotation in the box, and avoid friction drive core and mobile piston 6, spring 4 prevent core wearing and tearing and spring torsional deflection.

4, some breather holes 5 are arranged on the Storage Box sidewall, help the aeration-drying of core.

5, the box sidewall is provided with pointer groove 14, moves up and down for pointer 8.Pointer groove 14 is other with scale 9, deposits the height that can accurately indicate core behind the core.

6, on the mobile piston 6 and pointer groove 14 intersections are fixed with pointer 8, can move up and down with moving in pointer groove 14 of mobile piston 6 according to the flexible of spring 4, are used to indicate the core height.

7, the top of outer box wall pointer groove 14 is provided with active card 3, is used to write down core title and relevant data data.Can change at any time with the card of crossing.

Principle of work:

The groundwork principle of core Storage Box is: under the fixing situation of box internal diameter, regulate the interior height of box according to stretching of spring 4, guarantee that core is not collided and damages in the process that stores, transports.Utilize the pointer 8 that is fixed on the mobile piston 6 to indicate the height of core simultaneously, utilize the ventilation of core in the breather hole 5 assurance boxes on the box wall, promote the drying of core.

Using method:

(1) deposit core:

1, the internal diameter of core Storage Box is identical with the normal diameter of the core that is taken out, the box height then is divided into three kinds of 100mm+ h, 150mm+ h, 200mm+ h (shortest length after compressing when wherein h is for length of spring compressed) according to dissimilar cores, can choose suitable model according to the difference of getting core kind.

2, open the loam cake 2 of Storage Box.

3, core is put into Storage Box.

4, screw on the loam cake 2 that is taken off.This moment, lower cover 10 and mobile piston 6 compressed core, and pointer 8 indications are the height of core.

5, on the active card 3 on pointer groove 14 tops, indicate core title and relevant data, be convenient to seek and take, avoid core to obscure.

(2) take out core

Open the lower cover 10 of Storage Box, spring 4 elastic force can help core in the box is taken out.
