Description

Technical Field

[0001] This application relates to the field of storage box equipment, and in particular to a storage box for a cement standard consistency and setting time probe. Background Technology

[0002] The standard consistency of cement refers to the amount of water required for cement paste to reach a specified plasticity, i.e., the standard consistency state; it is an indicator of the "fluidity" of cement paste. The setting time of cement refers to the time required for cement to lose its plasticity and harden after being mixed with water; it is divided into initial setting time and final setting time, and is an indicator of the "hardening speed" of cement.

[0003] In related technologies, the standard consistency and setting time of cement can both be measured using the Vicat apparatus method. When determining the standard consistency of cement, a standard consistency test rod is typically inserted into the sample. By adjusting the amount of water added to the cement paste, the depth of the test rod's penetration is adjusted to 6 ± 1 mm; the amount of water used at this point is the standard consistency water quantity. When determining the setting time of cement, a sample is prepared according to the measured standard consistency water quantity and placed in a curing chamber. The initial setting time is measured every 5 to 10 minutes using a setting needle. The time taken to reach the initial setting time when the setting needle penetrates the cement paste to 4 ± 1 mm from the bottom plate is the initial setting time. The final setting time is measured every 15 to 30 minutes using a final setting needle. The time taken to reach the final setting time when the final setting needle leaves a mark on the surface of the cement paste without any annular indentation is the final setting time. To ensure the accuracy of the test results, the standard consistency test rod, initial setting needle, and final setting needle must be checked for integrity before testing. To reduce the risk of damage to standard consistency test rods, initial setting needles, and final setting needles when not in use, they are usually equipped with storage boxes for storing the test rods and cushioning pads for the test rods to fit snugly inside the storage boxes.

[0004] Regarding the aforementioned technologies, the inventors believe that the probe is difficult to remove when placed in the storage box. Utility Model Content

[0005] To address the issue of difficulty in retrieving the probe when it is placed in the storage box, this application provides a storage box for the probe of cement standard consistency and setting time.

[0006] The cement standard consistency and setting time probe storage box provided in this application adopts the following technical solution:

[0007] A cement standard consistency and setting time probe storage box includes a lower box body with a placement cavity and a buffer pad within the placement cavity. The buffer pad has a first arrangement groove for arranging the probe. The bottom surface of the buffer pad is further provided with a mounting groove communicating with the lower surface of the buffer pad. An ejection mechanism for ejecting the probe out of the first arrangement groove is arranged within the mounting groove. The ejection mechanism includes an ejection base plate hinged at one end to the bottom surface of the lower box body, an elastic structure abutting against the movable end of the ejection base plate and used to eject the probe from the first arrangement groove, a locking structure for locking the ejection base plate within the mounting groove, and an unlocking mechanism for unlocking the locking structure.

[0008] By adopting the above technical solution, the setting of the buffer pad and the first arrangement groove helps to reduce the risk of probe bending and damage. When the user takes the probe, he first operates the unlocking mechanism to unlock the locking structure located in the mounting groove. Driven by the elastic structure, the movable end of the bottom plate is lifted upward and the probe is pushed out of the first arrangement groove. At this time, the user can take the probe out of the storage box, thereby improving the problem that the probe is not easy to take out when it is placed in the storage box.

[0009] Optionally, the elastic structure includes a first column sleeve fixed to the bottom surface of the lower box body, a first column slidably installed on the first column sleeve, an abutment portion fixed to the top of the first column and abutting against the ejector base plate, and a support spring sleeved on the outside of the first column sleeve; one end of the support spring abuts against the bottom of the abutment portion and the other end abuts against the inner bottom surface of the lower box body.

[0010] By adopting the above technical solution, the specific structure of the elastic structure is disclosed. A first column sleeve is set on the bottom surface of the lower box body, and a first column is set inside the first column sleeve. A support spring is set outside the first column sleeve, so that the first column always has a vertical lifting tendency, and the abutting part always abuts against the bottom of the ejector plate. This realizes that the movable end of the ejector plate can push the probe out of the first arrangement slot, which helps to improve the problem that the probe is not easy to take out when placed in the storage box.

[0011] Optionally, the abutment portion is a hemispherical structure.

[0012] By adopting the above technical solution, the hemispherical structure has a large surface area, which ensures that the abutting part of the movable end of the ejector plate can always abut against the bottom surface of the ejector plate when it moves up and down.

[0013] Optionally, the locking structure includes a plunger groove formed on the end face of the movable end of the ejector base plate, a spring plunger installed in the plunger groove, and a locking groove formed on the side wall of the lower housing for locking the plunger protrusion of the spring plunger. When the plunger protrusion of the spring plunger is locked in the locking groove, the ejector base plate is located in the mounting groove.

[0014] By adopting the above technical solution, the specific structure of the locking mechanism is disclosed. A spring plunger is provided on the end face of the movable end of the ejector plate, and a locking groove is provided on the inner side wall of the lower box for locking the plunger protrusion of the spring plunger. This realizes that the locking mechanism locks the ejector plate in the mounting groove.

[0015] Optionally, the side wall of the lower housing is provided with a guide groove on the upper side of the locking groove for the plunger protrusion of the spring plunger to slide.

[0016] By adopting the above technical solution, the setting of the guide groove allows the plunger protrusion to slide along the arrangement direction of the guide groove, which helps to reduce the risk of the movable end of the ejector plate moving left and right.

[0017] Optionally, the bottom surface of the locking groove is provided with an unlocking through groove that extends to the outer wall of the lower box and is used for the arrangement of the unlocking mechanism; the unlocking mechanism includes an unlocking member that is slidably arranged in the unlocking through groove and an unlocking spring that drives the unlocking member to always move toward the outer wall of the lower box; the unlocking member has an unlocking part for abutting the spring plunger with a plunger protrusion, a sliding part that is slidably arranged in the unlocking through groove, and a pressing part for the user to press.

[0018] By adopting the above technical solution, an unlocking slot is opened on the outer side wall of the lower box body, extending to the bottom surface of the locking slot, and an unlocking mechanism is provided in the unlocking slot. When the user presses the pressing part of the unlocking component, the unlocking component will move towards the inner side of the lower box body. At this time, the unlocking part of the locking component will enter the locking slot and push the spring plunger out of the locking slot, push out the bottom plate to unlock, and under the drive of the elastic structure, push the probe out of the first arrangement slot, thereby making it convenient for the user to take out the probe from the storage box.

[0019] Optionally, the lower housing has a protective cover rotatably mounted on its outer side wall for closing the unlocking mechanism, and the outer side wall of the lower housing has a mounting portion for rotatably mounting the protective cover.

[0020] By adopting the above technical solution, the protective cover helps to reduce the risk of damage to the unlocking mechanism due to bumps or accidental unlocking of the locking structure.

[0021] Optionally, the protective cover has a first magnetic groove on the side facing the unlocking mechanism and a first magnetic sheet is disposed in the first magnetic groove. The lower box body has a second magnetic groove facing the first magnetic groove and a second magnetic sheet for attracting the first magnetic sheet is installed in the second magnetic groove.

[0022] By adopting the above technical solution, the setting of the first magnetic sheet and the second magnetic sheet realizes the magnetic closing of the protective cover on the outer wall of the lower box, which helps to further reduce the risk of damage to the unlocking mechanism due to bumps or accidental unlocking of the locking structure, and improves the sealing and durability of the unlocking mechanism.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. A cement standard consistency and setting time probe storage box, comprising a lower box body, a buffer pad arranged in the lower box body, and an ejection mechanism for ejecting the probe from the buffer pad. When the user takes out the probe, he first operates the unlocking mechanism to unlock the locking structure located in the mounting groove. Driven by the elastic structure, the movable end of the ejector base plate is lifted upward and the probe is ejected from the first mounting groove. At this time, the user can take out the probe from the storage box, thereby improving the problem that the probe is not easy to take out when placed in the storage box.

[0025] 2. By setting a first column sleeve on the bottom surface of the lower box and setting a first column inside the first column sleeve, and setting a support spring outside the first column sleeve, the first column always has a tendency to rise vertically, and the abutting part always abuts against the bottom of the ejector plate, thereby realizing that the movable end of the ejector plate can push the probe out of the first arrangement slot, which helps to improve the problem that the probe is not easy to take out when placed in the storage box.

[0026] 3. By opening an unlocking slot through the outer wall of the lower box to the bottom of the locking slot and setting an unlocking mechanism in the unlocking slot, when the user presses the pressing part of the unlocking member, the unlocking member will move towards the inner side of the lower box. At this time, the unlocking part of the locking member will enter the locking slot and push the spring plunger out of the locking slot, push out the bottom plate to unlock, and under the drive of the elastic structure, push the probe out of the first arrangement slot, so that the user can easily take out the probe from the storage box.
