Description

Technical Field

[0001] The utility model relates to the field of concrete specimens, in particular to a concrete specimen with an implanted anti-replacement label. Background Art

[0002] In the construction field, in order to supervise the quality of concrete entities, it is necessary to sample the used concrete and then transfer it to the supervision department for testing of concrete specimens. However, before transferring it to the supervision department, it is necessary to reduce the probability of the sampled concrete specimens being replaced.

[0003] Chinese Patent No. CN214067803U discloses an implanted anti-replacement label for concrete specimens, including a concrete specimen body. At the top of the front surface of the concrete specimen body, there is a second installation groove. An installation block is arranged in the second installation groove. At the top and bottom of the back surface of the installation block, embedded rods are fixedly connected. On both sides of the embedded rod, a number of bumps are symmetrically arranged at intervals along its axial direction. A groove is formed on the front surface of the installation block, and a second label is arranged in the groove. A sealing glue is arranged inside the groove and outside the second label. At the bottom of the front surface of the concrete specimen body, a first installation groove is formed. A first label is arranged in the first installation groove. The first label is connected to the installation block through a connecting rod.

[0004] The installation block in the above structure needs to be installed into the concrete specimen body when the concrete specimen body is not solidified. At this time, the embedded rods with a number of bumps arranged on the installation block can be inserted into the concrete specimen body. Then, waiting for the concrete specimen body to solidify can complete the installation of the installation block, thereby reducing the probability of the second label being replaced. However, after installing the installation block with the second label into the concrete specimen body, it still takes some time for the concrete specimen body to solidify. This results in a long gap between installing the installation block with the second label into the concrete specimen body and sending it for inspection, providing a large space for fraud, thus increasing the probability of fraud occurring. Content of the Utility Model

[0005] Aiming at the drawback that after installing the installation block with the second label into the concrete specimen body in the prior art, it still takes some time for the concrete specimen body to solidify, resulting in a long gap between installing the installation block with the second label into the concrete specimen body and sending it for inspection, providing a large space for fraud, thus increasing the probability of fraud occurring, the utility model provides a concrete specimen with an implanted anti-replacement label that can be installed into the concrete specimen after the concrete specimen solidifies.

[0006] To solve the above technical problems, the utility model is solved through the following technical solutions:

[0007] A concrete specimen with an implanted anti-exchange label comprises a solidified concrete body, a label and an internally hollow mounting block, a plug-in component for inserting the label into the mounting block is arranged on the side wall of the mounting block, a mounting structure for mounting the mounting block on the concrete body is arranged between the mounting block and the concrete body, the mounting structure comprises a fixed block arranged below the mounting block, an elastic component for connecting the fixed block and the mounting block and for pushing the mounting block away from the fixed block is arranged between the fixed block and the mounting block, a display groove for installing and displaying the label in the mounting block and a plug-in groove connected to the bottom of the display groove and for the mounting block and the fixed block to be inserted into the display groove from the side is arranged on the concrete body, the height of the plug-in groove is lower than the height of the display groove and higher than the sum of the thickness of the mounting block and the additional fixed block, an anti-exchange component for preventing the fixed block from escaping from the display groove and preventing the mounting block from moving toward the fixed block and escaping from the plug-in groove is arranged on the inner wall of the display groove, and a closing component for closing the plug-in groove when the fixed block is inserted into the display groove is fixedly arranged at one end of the fixed block.

[0008] By adopting the above scheme, the plug-in component arranged on the side wall of the mounting block enables the label to be installed inside the mounting block. When the concrete body solidifies, the mounting block can be squeezed first to move the mounting block toward the fixed block and compress the elastic component. Then, the mounting block and the fixed block can be inserted into the display slot from the plug-in slot. When the mounting block and the fixed block are moved into the display slot, the compressed elastic component will recover, thereby driving the mounting block to move toward the top of the display slot, making it easier for people to observe the label installed in the mounting block. When the mounting block moves to the top of the display slot, the anti-exchange component can be used to limit the downward movement of the mounting block, and at the same time, the fixed block can be prevented from moving downward. The anti-exchange component can be used to limit the position of the fixing block and the mounting block, thereby reducing the probability of the mounting block being removed from the concrete body for replacement and the probability of the label installed in the mounting block from the side wall of the mounting block being replaced. The provided closing component can close the plug-in slot when the mounting block and the fixed block are inserted into the display slot, thereby reducing the possibility of others removing the limit of the fixing block and the mounting block by the anti-exchange component from the plug-in slot, thereby further reducing the probability of the mounting block and the label in the mounting block being replaced. Because the mounting block with the label can be installed in the concrete body after the concrete is fixed, the time gap between the installation of the label and the inspection is reduced, thereby reducing the space for others to falsify and reducing the probability of falsification.

[0009] Preferably, the anti-replacement component includes a storage slot arranged on the side wall of the display slot and a limit block telescopically arranged in the storage slot and partially inserted into between the fixed block and the mounting block when extended; a retraction component is arranged on the limit block to drive the limit block to retract into the storage slot when the fixed block and the mounting block are inserted from the plug-in slot into the display slot; and a reset component is arranged between the limit block and the storage slot to drive the limit block to reset and insert between the fixed block and the mounting block when the pushing component drives the mounting block to move to the opening of the display slot.

[0010] By adopting the above scheme, the set limit block can be retracted into the storage slot by the retracting component during the process of the fixed block and the mounting block being inserted from the plug-in slot into the display slot. When the fixed block and the mounting block are moved from the plug-in slot to the display slot, the pushing component will drive the mounting block away from the fixed block. When the mounting block moves to the opening of the display slot, the mounting block and the limit block are separated from each other, and the limit block will be reset and inserted between the mounting block and the fixed block under the drive of the reset component, thereby reducing the probability of the mounting block and the limit block being removed and reducing the probability of the label in the mounting block being replaced.

[0011] Preferably, the retractable component includes an introduction slope arranged on the limiting block, and the introduction slope increases in inclination from an end close to the plug-in slot to an end away from the plug-in slot.

[0012] With the above solution, the guiding slope on the limit block can drive the limit block to retract into the receiving slot when the fixing block and the mounting block are inserted from the plug-in slot into the display slot, so that the fixing block and the mounting block are completely inserted into the display slot.

[0013] Preferably, the reset component includes a first spring whose two ends are respectively fixed to an end of the limiting block close to the receiving groove and the bottom surface of the receiving groove.

[0014] By adopting the above scheme, the first spring can be set to push the limiting block to partially extend out of the storage slot and be inserted between the mounting block and the fixed block when the mounting block moves into the display slot and the pushing component drives the mounting block to move to the opening of the display slot, thereby limiting the fixed block and reducing the probability of it falling out of the opening of the display slot. At the same time, the mounting block is limited to prevent it from approaching the fixed block and falling out of the plug-in slot, thereby reducing the probability of the mounting block and the label in the mounting block being replaced.

[0015] Preferably, the height of the limiting block is equal to the distance between the mounting block and the fixing block when the mounting block moves to the opening of the display slot.

[0016] By adopting the above scheme, the height of the limit block is set equal to the distance between the display slot and the fixed block when the installation block moves to the opening of the display slot, so that the installation block pushed to the opening of the display slot by the pushing component cannot move in the direction of the fixed block, thereby reducing the probability of the installation block being taken out and replaced from the plug-in slot due to its movement in the direction of the fixed block, and reducing the probability of the label being replaced.

[0017] Preferably, the elastic component comprises a second spring vertically arranged between the fixing block and the mounting block and having two ends respectively fixed to the two. A plurality of second springs are provided and arranged in a rectangular array between the fixing block and the mounting block.

[0018] With the above solution, after the mounting block is inserted from the insertion slot into the display slot, the second spring provided can push the mounting block towards the opening of the display slot.

[0019] Preferably, anti-displacement components are provided on at least one inner wall of the other side walls in the display slot that are not connected to the insertion slot.

[0020] With the above solution, setting anti-displacement components on different inner walls in the display slot can further reduce the probability of the fixing block slipping out of the display slot and the probability of the mounting block moving towards the fixing block and slipping out of the insertion slot.

[0021] Preferably, the sealing component includes a sealing block with one end connected to the fixing block and having the same size as the insertion slot.

[0022] With the above solution, the sealing block with one end connected to the fixing block can seal the insertion slot when the fixing block and the mounting block are inserted from the insertion slot into the display slot, reducing the probability of others releasing the limit of the anti-displacement component on the fixing block and the mounting block from the insertion slot, thereby reducing the probability of the mounting block and the label inside the mounting block being replaced.

[0023] Preferably, the insertion component includes a mounting groove provided on the side wall of the mounting block and communicating with the inside of the mounting block, and the mounting groove is provided in the middle of the side wall of the mounting block.

[0024] With the above solution, the label can be installed in the mounting block for display through the provided mounting groove, and when the mounting groove is provided in the middle of the side wall of the mounting block, the probability of the label slipping out of the mounting groove due to the erection of the mounting groove can be reduced.

[0025] The utility model has a significant technical effect due to the adoption of the above technical scheme: the plug-in component arranged on the side wall of the installation block enables the label to be installed inside the installation block, and when the concrete body solidifies, the installation block can be squeezed first, so that the installation block moves toward the fixed block and the elastic component is compressed, and then the installation block and the fixed block can be inserted into the display groove from the plug-in groove, and when the installation block and the fixed block move into the display groove, the compressed elastic component will recover, thereby driving the installation block to move toward the top of the display groove, so that people can observe the label installed in the installation block, and when the installation block moves to the top of the display groove, the downward movement of the installation block can be prevented by the anti-exchange component. The limit is set, and the upward escapement of the fixed block is limited at the same time, thereby reducing the probability of the installation block being removed from the concrete body for replacement, and reducing the probability of the label installed in the installation block from the side wall of the installation block being replaced. The provided closing component can close the plug-in slot when the installation block and the fixed block are inserted into the display slot, thereby reducing the possibility of others removing the limit of the fixed block and the installation block by the anti-exchange component from the plug-in slot, thereby further reducing the probability of the installation block and the label in the installation block being replaced. Because the installation block with the label can be installed in the concrete body after the concrete is fixed, the time gap between the installation of the label and the inspection is reduced, thereby reducing the space for others to falsify and reducing the probability of falsification.

[0035] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] Example

[0037] A concrete specimen with an embedded anti-substitution tag, reference Figures 1-5 , Figures 7-8 , comprising a solidified concrete body 1, a label 2 and a mounting block 3 with a hollow interior, a plug-in component for inserting the label 2 into the mounting block 3 is arranged on the side wall of the mounting block 3, a mounting structure for mounting the mounting block 3 to the concrete body 1 is arranged between the mounting block 3 and the concrete body 1, the mounting structure comprises a fixing block 4 arranged below the mounting block 3, an elastic component for connecting the fixing block 4 and the mounting block 3 and for pushing the mounting block 3 away from the fixing block 4 is arranged between the fixing block 4 and the mounting block 3, a display groove 5 for installing and displaying the label 2 in the mounting block 3 and a display groove 5 having a bottom portion thereof and a bottom portion thereof and a bottom portion thereof and a bottom portion thereof and a bottom portion thereof are arranged on the concrete body 1. The plugging slot 6 is connected and is used for the mounting block 3 and the fixing block 4 to be inserted into the display slot 5 from the side. The height of the plugging slot 6 is lower than the height of the display slot 5 and higher than the sum of the thicknesses of the mounting block 3 and the fixing block 4. An anti-exchange component is provided on at least one side wall of the other side walls of the display slot 5 that are not connected to the plugging slot 6. The anti-exchange component is used to prevent the fixing block 4 from escaping from the display slot 5 and to prevent the mounting block 3 from moving toward the fixing block 4 and escaping from the plugging slot 6. In this embodiment, two anti-exchange components are symmetrically arranged on the side walls of the display slot 5. A closing component is fixedly arranged at one end of the fixing block 4 to close the plugging slot 6 when the fixing block 4 is inserted into the display slot 5.

[0038] refer to Figures 2-4 , Figure 6, the anti-replacement component includes a storage groove 7 provided on the side wall of the display groove 5 and a limiting block 8 telescopically arranged in the storage groove 7 and partially inserted between the fixed block 4 and the mounting block 3 when extended. The height of the limiting block 8 is equal to the distance between the mounting block 3 and the fixed block 4 when the mounting block 3 moves to the opening of the display groove 5. A retraction component is provided on the limiting block 8 to drive the limiting block 8 to retract into the storage groove 7 when the fixed block 4 and the mounting block 3 are inserted into the display groove 5 from the insertion groove 6. A reset component is provided between the limiting block 8 and the storage groove 7 to drive the limiting block 8 to reset and insert between the fixed block 4 and the mounting block 3 when the pushing component drives the mounting block 3 to move to the opening of the display groove 5. The retraction component includes an introduction inclined surface 9 provided on the limiting block 8, and the introduction inclined surface 9 is inclined and increases from the end close to the insertion groove 6 to the end far from the insertion groove 6. The reset component includes a first spring 1001 whose two ends are respectively fixed to the end of the limiting block 8 close to the storage groove 7 and the bottom surface of the storage groove 7.

[0039] Reference Figures 2-5 , the elastic component includes a second spring 1002 vertically arranged between the fixed block 4 and the mounting block 3 and fixed to both ends respectively. A plurality of second springs 1002 are provided and arranged in a rectangular array between the fixed block 4 and the mounting block 3. The height of the limiting block 8 is equal to the distance between the mounting block 3 and the fixed block 4 when the mounting block 3 moves to the opening of the display groove 5.

[0040] Reference Figure 1 , Figure 5 , the sealing component includes a sealing block 11 with one end connected to the fixed block 4 and the same size as the insertion groove 6. The insertion component includes a mounting groove 12 provided on the side wall of the mounting block 3 and communicating with the inside of the mounting block 3. The mounting groove 12 is provided in the middle of the side wall of the mounting block 3 and the hollow space inside the mounting block 3 is larger than the size of the label 2. After the mounting block 3 and the fixed block 4 are installed in the display groove 5, the limiting block 8 will block the mounting block 3 from moving out of the insertion groove 6 in the direction of the fixed block 4 and the fixed block 4 from moving out of the top of the display groove 5 in the direction of the mounting block 3, making it more difficult to remove and replace the mounting block 3 from the concrete body 1. At this time, if someone wants to fake it, they may start from the mounting groove 12 on the mounting block 3 and directly replace the label 2 inside the mounting block 3. Because the mounting groove 12 is provided in the middle of the side wall of the mounting block 3, it is more difficult to take out the label 2 from inside the mounting block 3 and it takes a longer time. At this time, if someone wants to fake it, they can insert a new label 2 into the mounting block 3 from the mounting groove 12 to cover the original label 2. Because the size of the hollow space inside the mounting block 3 is larger than the size of the label 2, just by shaking the concrete body 1, it can be seen whether there are multiple labels 2 inside the mounting block 3, thus reducing the probability of faking.

[0041] The fixed installation process of the label 2 and the installation block 3: First, pour the concrete slurry into the mold to form a square concrete specimen. Before the concrete slurry solidifies, insert cuboids for forming the display groove 5, the insertion groove 6, and the storage groove 7 into the concrete slurry respectively, and take them out after the concrete slurry solidifies, so as to form the display groove 5, the insertion groove 6, and the storage groove 7 in the concrete body 1. Then, install the first spring 1001 and the limiting block 8 into the storage groove 7. After that, press the installation block 3 to make the installation block 3 move towards the fixed block 4. At this time, the second spring 1002 arranged between the installation block 3 and the fixed block 4 will be compressed. Then, insert the installation block 3 and the fixed block 4 into the display groove 5 from the insertion groove 6 on the side of the concrete body 1. During the insertion process of the installation block 3 and the fixed block 4, they will be in contact with the guiding inclined surface 9 on the limiting block 8, so as to squeeze the limiting block 8 to make the limiting block 8 retract into the storage groove 7. When the installation block 3 and the fixed block 4 are completely inserted into the display groove 5, the first spring 1001 will recover and push the installation block 3 to move towards the top of the display groove 5. When the installation block 3 moves to the top of the display groove 5, the limiting block 8 will lose the extrusion of the installation block 3 on it, and the first spring 1001 will recover and push the limiting block 8 to partially extend out of the storage groove 7 and insert between the installation block 3 and the fixed block 4. At this time, the limiting block 8 will limit the downward movement of the installation block 3, reducing the probability that the installation block 3 and the fixed block 4 are taken out from the insertion groove 6 due to the downward movement of the installation block 3. At the same time, the limiting block 8 will also limit the upward movement of the fixed block 4, reducing the probability that the installation block 3 and the fixed block 4 are disengaged from the top of the display groove 5 due to the upward movement of the fixed block 4. And the sealing block 11 connected to one end of the fixed block 4 can seal the insertion groove 6 when the fixed block 4 is inserted into the display groove 5, so as to prevent others from pushing the limiting block 8 to retract from the insertion groove 6, further reducing the probability that the installation block 3 and the fixed block 4 are removed and replaced from the concrete body 1.
