[0021] The following is combined with Figure 1-7 This application is described in further detail.

[0022] The embodiment of the present application discloses a sample box pull-out structure for a cement curing box for testing.

[0023] Reference Figure 1 A sample box pull-out structure of a cement curing box for testing, comprising a curing box 1 placed on the ground and a curing rack 2 installed in the curing box 1. The curing box 1 is hinged with a door 11, and a closed cement curing environment can be formed inside it. The curing rack 2 is provided with a plurality of pull-out slots 21 in an array on one side close to the door 11, and a sample box 3 for placing cement is slidably arranged in each of the pull-out slots 21. The curing box 1 in the present application can meet the requirements of cultivating multiple cement samples at the same time, thereby improving the curing efficiency.

[0024] Reference Figure 2 and Figure 3 A handle 31 is integrally connected to one side of the sample box 3 close to the box door 11, so that people can hold it and easily add curing materials.

[0025] Preferably, a baffle 32 is integrally connected to the inner side of the sample box 3 along the circumferential direction. When the sample box 3 moves too fast or shakes violently, the baffle 32 can effectively prevent the internal slurry from spilling out in large quantities, thus playing a protective role.

[0026] Referring to Figures 2 and Figure 3 Two supporting pulleys 4 are symmetrically mounted on the two opposite side walls in the vertical direction in the plurality of drawing grooves 21. The two supporting pulleys 4 are respectively in contact with the two sides of the sample box 3 to support the sample box 3 and change the sliding of the sample box 3 into rolling when it is drawn, so as to facilitate the drawing and reduce wear.

[0027] Two L-shaped bars 5 are symmetrically connected to the sample box 3. The tops of the two support pulleys 4 roll against the bottom sides of the two bars 5 that protrude horizontally to the outside of the sample box 3 to avoid direct contact between the support pulley 4 and the sample box 3, which would cause increased wear.

[0028] Reference Figure 4 Furthermore, the bar frame 5 includes an integrally connected transverse portion 51 and a vertical portion 52 located vertically below the transverse portion 51. The vertical portion 52 is fixedly connected to the side wall of the sample box 3 at a side away from the transverse portion 51, and the support pulley 4 is movably abutted against the bottom side of the transverse portion 51. The vertical portion 52 is provided with a slide groove 521 along the length direction of the sample box 3 at a side away from the sample box 3, a slider 6 is slidably arranged in the slide groove 521, and a spring 7 is connected between the side of the slider 6 away from the handle 31 and the side wall of the slide groove 521.

[0029] A limit assembly 8 is provided on the slider 6 to prevent the sample box 3 from accidentally falling out of the drawing slot 21 during the drawing process. At the same time, the structure of the limit assembly 8 and the spring 7 can also provide a buffer for the sample box 3 to prevent the sample box 3 from moving too fast when the tester exerts too much force, thereby preventing the cement slurry in the box from splashing out.

[0030] Reference Figure 4 Specifically, the limiting assembly 8 includes a block 81 rotatably arranged on the slider 6 at a side away from the sample box 3 and a detachable positioning pin 82 penetrating the block 81, and the positioning pin 82 is used to fix the position of the block 81 on the slider 6. The inner side of the block 81 is an arc-shaped structure, and abuts and cooperates with one side of the support pulley 4 along the length direction of the sample box 3 to form a clamping effect.

[0031] The slider 6 is provided with a pin hole 1 61 and a pin hole 2 62, both of which are engaged with the positioning pin 82. The pin hole 1 61 and the pin hole 2 62 correspond to two positions of the positioning pin 82. The positioning pin 82 passes through one side of the block 81 and is inserted into the pin hole 1 61 or the pin hole 2 62 to limit the rotation of the block 81 around the center of the slider 6. The pin hole 1 61 is located at one end of the side of the slider 6 close to the handle 31, and the pin hole 2 62 is located at the opposite end of the same side of the slider 6.

[0032] Reference Figure 5 When the limit pin is located in the pin hole 1 61, the block 81 is located on the side of the slider 6 close to the handle 31. At this time, the block 81 will not restrict the sample box 3 from being taken out, and the inspector can easily remove or install the sample box 3, making it more convenient to clean the sample box 3 and place large maintenance materials.

[0033] Reference Figure 6 When the limit pin is located in the second pin hole 62, the block 81 is located on the side of the slider 6 away from the handle 31. At this time, the block 81 movably abuts against the support pulley 4. When the sample box 3 is pulled out, the block 81 forms a clamping structure with the support pulley 4, and the sample box 3 cannot be smoothly pulled out and removed.

[0034] At the same time, when the inspector pulls the sample box 3 outward, the support pulley 4 presses against the block 81. Since the block 81 is arranged on the slider 6, the spring 7 will give a reverse force to the sample box 3, slowing down the pulling speed of the sample box 3 and improving the buffering effect.

[0035] Reference Figure 4 and Figure 6Furthermore, in order to make the operation more convenient for the inspectors and avoid the complicated operation of inserting the positioning pin 82 back and forth, the positioning pin 82 is designed to be fixedly connected to the clamping block 81. Specifically, the end of the positioning pin 82 close to the sample box 3 is connected with a compression spring 83, and the end of the compression spring 83 away from the positioning pin 82 is connected with a clamping contact point 84 whose size matches that of the pin hole 1 61 and the pin hole 2 62. The clamping contact point 84 is a hemispherical structure, so that when the clamping block 81 is fixed at any position of the pin hole 1 61 and the pin hole 2 62 on the slider 6, a part of the end of the clamping contact point 84 away from the compression spring 83 is located in the pin hole 1 61 or the pin hole 2 62, and the compression spring 83 can completely enter the clamping block 81 when it is contracted.

[0036] When the position of the block 81 needs to be changed, the inspector only needs to press the block 81 to rotate it, which is easy to operate. And because the force exerted by the support pulley 4 on the block 81 is a lateral force, the block 81 will not be easily moved, and the structure is stable.

[0037] At the same time, there is a gap between the bottom of the sample box and the pull-out slot 21. Since the card block 81 is relatively long, when taking out the sample box, the card block 81 and the support pulley 4 can be pressed by hand at the same time to make them rotate synchronously, making the operation of moving the card block 81 easier.

[0038] Reference Figure 7 Preferably, the block 81 is provided with a plurality of rollers 811 rotating along the arc surface near the inner side of the support pulley 4. The plurality of rollers 811 are in contact with the support pulley 4 to convert the friction between the block 81 and the support pulley 4 into rolling, thereby extending the service life of the block 81.

[0039] Reference Figure 6 and Figure 7 Preferably, when the spring 7 is in a normal state, the distance between the slider 6 and the handle 31 is between one half and two thirds of the total length of the sample box 3 toward the end away from the handle 31, so as to ensure that the block 81 can be easily moved while preventing the inspector from generating reverse elastic force too early when pulling the sample box 3, thereby increasing the difficulty of operation for the inspector.

[0040] This structure makes it easier for inspectors to put small-sized curing materials into the sample box 3 .

[0041] The implementation principle of the sample box pull-out structure of the cement curing box for testing in the embodiment of the present application is as follows: In the initial state, the positioning pin 82 is located in the pin hole 1 61, and the sample box 3 can be smoothly and quickly placed in the draw-out slot 21. Then, the block 81 is pushed, and the positioning pin 82 is driven into the pin hole 2 62. At this time, the block 81 is located on the side of the support pulley 4 away from the handle 31. The block 81 abuts against the support pulley 4, and while limiting the activity of the sample box 3, it can also provide a buffer for the drawing action of the sample box 3.

[0042] This structure makes the sample box 3 easy to assemble and disassemble, and has a simple structure and high practicality.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
