Description

Technical Field

[0001] This application relates to the field of mortar curing box technology, and in particular to a mixed mortar curing box. Background Technology

[0002] The mortar curing box is a device for standard curing of mortar samples. It adopts an intelligent temperature and humidity control system, which accurately commands functions such as heating, humidification and dehumidification. It is suitable for scientific research and quality inspection departments to perform standard curing of mortar specimens.

[0003] In existing technologies, most mixed mortar curing boxes divide the space into multiple curing compartments by installing and fixing partitions within the box. Because the partitions are fixed, the size of the curing compartments is not adjustable, making the curing box unsuitable for mortar samples of varying sizes. Utility Model Content

[0004] To facilitate the adjustment of the partition height and achieve flexible adjustment of the curing space size to accommodate mortar samples of different sizes, this application provides a mixed mortar curing box.

[0005] The mixed mortar curing box provided in this application adopts the following technical solution: A mixed mortar curing box includes a box body and a partition. Pre-installed rods are symmetrically arranged on both sides of the partition. A set of locking blocks is symmetrically arranged on the side of the pre-installed rods away from the partition. The set of locking blocks is slidably connected to the pre-installed rods along directions of mutual proximity or distance. A locking mechanism for driving the locking blocks to slide is provided on the pre-installed rods. A slot is formed on the opposite side of each locking block. Several vertically spaced grooves are symmetrically arranged on both side walls of the box body. These grooves are used to install the pre-installed rods. Each groove includes a locking slot corresponding to a locking block, into which the locking block extends. An integrally formed engaging portion is formed at the opening of the locking slot, extending into and abutting against the slot.

[0006] By adopting the above technical solution, when it is necessary to adjust the height of the partition to change the size of the curing space, a locking mechanism drives a set of two locking blocks closer together, causing the locking grooves on the locking blocks to separate from the locking slots, allowing the pre-installed rod to be removed from the current slot group. Then, the pre-installed rod is moved to the slot group at the target height, the locking blocks are inserted into the locking slots, and the locking mechanism again drives the set of locking blocks away from each other, causing the locking grooves to re-engage with the locking slots and abut against each other, thus fixing the partition at the target height. This facilitates adjustment of the partition height, enabling flexible adjustment of the curing space to accommodate mortar samples of different sizes.

[0007] Preferably, the pre-installed rod has a movable cavity along its length, and two sliding blocks slide and engage with each other along the length of the movable cavity. The sliding blocks correspond one-to-one with the locking blocks, and the locking blocks extend into the movable cavity and are fixedly connected to the corresponding sliding blocks.

[0008] By adopting the above technical solution, the sliding block slides and cooperates with the movable cavity in the movable cavity, providing guidance for the directional movement of the locking block, ensuring that the locking block slides in a preset direction: that is, in a direction that moves closer or further away from each other, preventing the locking block from deviating during the sliding process, and improving the support stability of the locking block for the pre-installed rod.

[0009] Preferably, the locking mechanism includes a spring, one end of which is fixedly connected to the end wall of the movable cavity, and the other end is fixedly connected to the sliding block. The spring drives the sliding block to approach the end wall of the movable cavity.

[0010] By adopting the above technical solution, the spring force drives the sliding block to move towards the end wall of the movable cavity, thereby causing the locking blocks to move away from each other, so that the slot sleeve moves towards the locking part, and the pre-installed rod is stably installed; when it is necessary to disassemble the pre-installed rod, it is only necessary to overcome the spring force to bring the locking blocks closer to each other, and the fixing of the slot and the locking part can be released.

[0011] Preferably, the locking mechanism further includes a winding wheel, a tension rope, and a rotating component. The winding wheel is rotatably disposed in the movable cavity and is located between two sliding blocks. One end of the tension rope is fixedly connected to the sliding block, and the other ends of both tension ropes are fixedly connected to the peripheral wall of the winding wheel. The rotating component is used to drive the winding wheel to rotate.

[0012] By adopting the above technical solution, the rotating component drives the winding wheel to rotate. When the winding wheel rotates, it pulls two tension ropes to simultaneously wind around its own peripheral wall. Each tension rope pulls a sliding block closer to the winding wheel, realizing the mutual approach of the two sliding blocks. This, in turn, drives the locking blocks to approach each other and move away from the locking part, making it easier to remove the pre-installed rod from the slot. When the rotating component is released, under the action of the spring force, the sliding block drives the locking block to reset, causing the winding wheel to rotate in the opposite direction and releasing the tension ropes.

[0013] Preferably, the rotating component is a lever, which is fixedly connected to the winding wheel. The movable cavity has a groove for the lever to extend out of the movable cavity, and the lever abuts against the side wall of the groove.

[0014] By adopting the above technical solution, the operator can directly drive the winding wheel to rotate by moving the lever that extends out of the movable cavity. The operation is simple, and the lever acts as a lever, making it easier to drive the winding wheel to rotate. The lever abuts against the side wall of the groove to limit the excessive rotation of the winding wheel, avoid the tension rope from being too loose and causing deviation, and improve stability.

[0015] Preferably, a reversing wheel corresponding to the tension rope is rotatably arranged inside the movable cavity. The reversing wheel abuts against the tension rope and is used to guide the tension rope into the winding wheel.

[0016] By adopting the above technical solution, the reversing wheel changes the direction of force and travel of the tension rope, making the tension rope more smoothly wound into the winding wheel. If the reversing wheel is not set, then: because the tension rope between the winding wheel and the sliding block is relatively long, when the tension rope winds around the winding wheel, the main body of the tension rope (the part outside the winding wheel) tilts with the winding action. On the one hand, the direction of the tension of the tension rope is no longer parallel to the sliding direction of the sliding block, and the effective force is reduced. On the other hand, the distance that the tension rope pulls the sliding block to slide will be shortened, reducing the effective stroke of the sliding block.

[0017] Preferably, both the winding wheel and the reversing wheel have grooves on their peripheral walls for the insertion of the tension rope.

[0018] By adopting the above technical solution, the rope groove can limit the tension rope, prevent the tension rope from deviating during winding or movement, and prevent it from slipping off the winding wheel or reversing wheel, thus ensuring the stable cooperation between the tension rope and the winding wheel and reversing wheel, and improving the overall reliability of the locking and releasing mechanism.

[0019] Preferably, the pre-installed rod has a slot along its length on the side facing the partition, and the partition is inserted into the slot.

[0020] By adopting the above technical solution, the partition and the pre-installed rods are detachably connected through slots, which makes the following possible: First, when installing the partition, two pre-installed rods can be installed in the corresponding positions first, and then the partition can be inserted, which facilitates the installation of the pre-installed rods; Second, when taking out mortar samples, the partition can be pulled out directly without disassembling the pre-installed rods; Third, when the partition is damaged or needs to be replaced with a partition of a different specification (such as replacing it with a mesh partition with a different mesh size), the partition can be directly removed from the slot for replacement, which is convenient to operate and facilitates maintenance and replacement of parts.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a pre-installed rod, locking block, locking release mechanism, slot, locking groove, snap-fit ​​part, movable cavity, and sliding block, when it is necessary to adjust the height of the partition to change the size of the curing space, the locking release mechanism drives a set of two locking blocks to move closer to each other, so that the slot on the locking block separates from the snap-fit ​​part of the locking groove. The pre-installed rod is taken out from the current slot group. Then the pre-installed rod is moved to the slot group at the target height, the locking block is inserted into the locking groove, and the locking release mechanism drives a set of locking blocks to move away from each other. The slot is re-fitted onto the snap-fit ​​part and abuts against each other, so that the partition is fixed at the target height. This makes it easy to adjust the height of the partition and realize the flexible adjustment of the curing space size to adapt to mortar samples of different sizes. 2. By setting up a spring, winding wheel, tension rope, rotating part, lever, and slot, the lever is turned to drive the winding wheel to rotate. The winding wheel pulls two tension ropes to wind around its own peripheral wall at the same time. Each tension rope pulls a sliding block close to the winding wheel, realizing the mutual approach of the two sliding blocks. This, in turn, drives the locking blocks to approach each other and move away from the locking part, making it easier to remove the pre-installed rod from the slot. When the lever is released, under the action of the spring force, the sliding blocks drive the locking blocks to reset, drive the winding wheel to rotate in the opposite direction, and release the tension rope. 3. By setting up a reversing wheel and rope groove, the reversing wheel changes the direction of force and travel of the tension rope, making the tension rope more smoothly wound into the winding wheel. The rope groove acts as a limit for the tension rope, preventing the tension rope from deviating during winding or movement. The reversing wheel and rope groove guide and constrain the movement of the tension rope, improving the stability of the tension rope. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a mixed mortar curing box. (Refer to...) Figure 1 and Figure 2 It includes a housing 1 and partitions 3. Several partitions 3 are arranged vertically at intervals inside the housing 1. In this embodiment, there are three partitions 3. Pre-installation rods 2 are symmetrically arranged on the left and right sides of the partitions 3. The length direction of the pre-installation rods 2 is parallel to the front and back direction. The side of the pre-installation rods 2 facing the partitions 3 has a slot 23 along its length direction. The partitions 3 are inserted into the slots 23 of the pre-installation rods 2 on both sides.

[0029] Reference Figures 2 to 4 On the side of the pre-installed rod 2 away from the partition plate 3, a set (i.e., two) of locking blocks 21 are symmetrically arranged front and back. The set of locking blocks 21 slides along the direction of mutual approach or distance (i.e., the front-back direction in this embodiment) to connect with the pre-installed rod 2. Specifically, a movable cavity 22 is formed along the length of the pre-installed rod 2. Two sliding blocks 221 slide along the length of the movable cavity 22, with each sliding block 221 corresponding to a locking block 21. A through groove is formed on the side of the pre-installed rod 2 away from the partition plate 3 for the locking blocks 21 to extend into the movable cavity 22. The locking blocks 21 extend into the movable cavity 22 through the through groove and are fixedly connected to the corresponding sliding blocks 221. The sliding engagement of the sliding blocks 221 with the movable cavity 22 provides guidance for the directional movement of the locking blocks 21.

[0030] Reference Figure 3 and Figure 4 The pre-installed rod 2 is equipped with a locking mechanism 4 for driving the locking block 21 to slide. A set of locking blocks 21 has a slot 211 on one side opposite to each other. Several slots are symmetrically arranged vertically on the left and right side walls of the housing 1. The slots are used to install the pre-installed rod 2. Specifically, the slots include a set of locking slots 11 corresponding to the locking block 21. The set (i.e., two) of locking slots 11 are symmetrical front and back. The locking slots 11 allow the locking block 21 to extend into them. The opening of the locking slot 11 has an integrally formed locking part 12, which extends into the locking slot 211 and abuts against the locking slot 211.

[0031] Reference Figure 1 and Figure 3 When the height of the partition 3 needs to be adjusted to change the size of the maintenance space, first pull the partition 3 out of the slots 23 of the pre-installed rods 2 on the left and right sides. Drive the two sliding blocks 221 to move the locking blocks 21 closer together through the locking mechanism 4, so that the slots 211 on the locking blocks 21 separate from the locking parts 12 of the locking grooves 11. Then, the two locking blocks 21 on the pre-installed rods 2 can be removed from the current slot group. Then, move the pre-installed rods 2 to the slot group at the target height, insert the locking blocks 21 into the locking grooves 11, and then drive a set of locking blocks 21 away from each other through the locking mechanism 4. The slots 211 are re-fitted onto the locking parts 12 and abut against each other. Finally, insert the partition 3 into the slots 23 of the pre-installed rods 2 on the left and right sides to fix the partition 3 at the target height.

[0032] To facilitate the sliding of the locking block 21, refer to... Figure 3 and Figure 4The locking and releasing mechanism 4 includes a spring 41, a winding wheel 42, a tension rope 43, and a rotating component. One end of the spring 41 is fixedly connected to the end wall of the movable cavity 22, and the other end is fixedly connected to the sliding block 221. The elastic force released by the spring 41 is a contraction force, which drives the sliding block 221 closer to the end wall of the movable cavity 22. The winding wheel 42 is rotatably disposed in the movable cavity 22, located between the two sliding blocks 221, and the rotation axis of the winding wheel 42 is parallel to the left and right direction. One end of the tension rope 43 is fixedly connected to the end of the sliding block 221 away from the spring 41, and the other ends of both tension ropes 43 are fixedly connected to the peripheral wall of the winding wheel 42. The rotating component is used to drive the winding wheel 42 to rotate so as to wind the tension rope 43. Specifically, the rotating component is a lever 44, which is fixedly connected to the peripheral wall of the winding wheel 42. A slot 222 is provided at the bottom of the movable cavity 22 for the lever 44 to extend out of the movable cavity 22. The lever 44 extends beyond the pre-installed rod 2 and is located below the pre-installed rod 2. The lever 44 abuts against the side wall of the slot 222 to prevent the tension rope 43 from becoming excessively slack and unstable.

[0033] Reference Figure 3 and Figure 4 The operator directly drives the winding wheel 42 to rotate by turning the lever 44 extending from the movable cavity 22. When the winding wheel 42 rotates, it pulls the two tension ropes 43 to simultaneously wind around its own peripheral wall. Each of the two tension ropes 43 pulls a sliding block 221 closer to the winding wheel 42, realizing the mutual approach of the two sliding blocks 221. This, in turn, causes the locking blocks 21 to move closer to each other and away from the locking part 12, making it easier to remove the locking blocks 21 on the pre-installed rod 2 from the slot. When the lever 44 is released, under the action of the spring 41, the sliding blocks 221 drive the locking blocks 21 to reset, and pull the tension ropes 43 to drive the winding wheel 42 to rotate in the opposite direction.

[0034] To further improve the stability of the tension rope 43, refer to Figure 4 A reversing wheel 45, corresponding to the tension rope 43, is rotatably mounted inside the movable cavity 22. The reversing wheel 45 is positioned close to the winding wheel 42, and its rotation axis is parallel to the left-right direction. The reversing wheel 45 abuts against the tension rope 43, ensuring that the portion of the tension rope 43 between the sliding block 221 and the reversing wheel 45 is parallel to the sliding direction of the sliding block 221. The reversing wheel 45 guides the tension rope 43 into the winding wheel 42. Both the winding wheel 42 and the reversing wheel 45 have rope grooves 46 on their peripheral walls for the tension rope 43 to be embedded in. The rope grooves 46 limit the left-right movement of the tension rope 43, preventing it from moving left or right.

[0035] The implementation principle of a mixed mortar curing box according to an embodiment of this application is as follows: When it is necessary to adjust the height of the partition 3 to change the size of the curing space, the partition 3 is first pulled out from the slots 23 of the pre-installed rods 2 on the left and right sides. The lever 44 at the bottom of the pre-installed rod 2 is moved to drive the winding wheel 42 to rotate. The winding wheel 42 pulls two tension ropes 43 to simultaneously wind around its own peripheral wall. Each tension rope 43 pulls a sliding block 221 close to the winding wheel 42, causing the two sliding blocks 221 to move the locking blocks 21 closer to each other. This separates the locking groove 211 on the locking block 21 from the locking groove 11's locking engagement part 12, allowing the two locking blocks 21 on the pre-installed rod 2 to be removed from the current slot group.

[0036] The pre-installed rod 2 is then moved to the groove at the target height. The locking block 21 is inserted into the locking groove 11, and the lever 44 is released. Under the elastic force of the spring 41, the sliding block 221 drives the locking block 21 to reset, and pulls the tension rope 43 to rotate the winding wheel 42 in the opposite direction. The sliding block 221 drives the locking blocks 21 to move away from each other, and the slot 211 re-fits onto the locking part 12 and abuts against it. Finally, the partition 3 is inserted into the slots 23 of the pre-installed rods 2 on both sides, fixing the partition 3 at the target height. This allows for easy adjustment of the height of the partition 3, enabling flexible adjustment of the curing space to accommodate mortar samples of different sizes.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
