Description
Technical Field
[0001] This utility model relates to the field of cement component technology, specifically to an adjustable-size cement component. Background Technology
[0002] In building construction and municipal engineering, cement components are widely used in supporting structures, fencing, and pipeline protection due to their high strength and durability. Currently, most cement components on the market are prefabricated, fixed-size structures; their dimensions are determined during the production process and cannot be flexibly adjusted to meet the actual needs of on-site construction.
[0003] The existing defects are as follows: On the one hand, the construction party needs to purchase cement components of various specifications in advance according to the size requirements of different projects. This not only increases the initial procurement cost and storage space occupation, but may also lead to idle or short-supply of components due to size estimation errors, affecting the construction progress. On the other hand, when the actual size on site does not match the size of the precast components, it is often necessary to process them by cutting and grinding on site. This process not only consumes manpower and time costs, but also easily damages the internal structural integrity of the cement components, resulting in a decrease in component strength and creating potential structural safety hazards. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable-size cement component to solve the problem mentioned in the background art that some cement components cannot be adjusted in size or are prone to sliding and shifting when the size is adjusted.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-size cement component, comprising an upper cement component, a first sliding strip, and a first T-shaped groove. The upper cement component is hollow inside. A first sliding strip and a second sliding strip are provided on the inner wall side of the upper cement component. The first and second sliding strips are symmetrically distributed on the left and right sides of the inner wall of the upper cement component. A first slider is provided at the bottom of the outer wall of the first sliding strip, and a second slider is provided at the bottom of the outer wall of the second sliding strip. The first sliding strip is engaged with the vertical groove of the first T-shaped groove, and the first slider is engaged with the horizontal groove of the first T-shaped groove. The first T-shaped groove is composed of a vertical groove and a horizontal groove. The second sliding strip is engaged with the vertical groove of the second T-shaped groove, and the second slider is engaged with the horizontal groove of the second T-shaped groove. The first T-shaped groove and the second T-shaped groove are provided on the outer wall side of the cement cylinder. A first limiting block and a second limiting block are provided at the top of the outer wall of the cement cylinder.
[0006] Preferably, a first limiting block is provided at the top of the first T-slot, and a second limiting block is provided at the top of the second T-slot. The first limiting block and the second limiting block have the same structure and size. The first limiting block is convex and has two screw holes at the top of its outer wall, through which bolts are inserted.
[0007] Preferably, the top of the outer wall of the cement cylinder is provided with four screw holes. The first group of two screw holes is provided on the left and right sides of the top of the first T-slot, and the second group of two screw holes is provided on the left and right sides of the top of the second T-slot. The first group of screw holes is engaged with the bolt in the first limiting block, and the second group of screw holes is engaged with the bolt in the second limiting block.
[0008] Preferably, the inner wall of the upper cement component is provided with two large grooves, which are circular grooves, and the two large grooves are symmetrically distributed on the left and right sides of the inner wall of the upper cement component. The outer wall of the upper cement component is provided with two small grooves, which are circular grooves, and the two small grooves are symmetrically distributed on the left and right sides of the outer wall of the upper cement component. The two small grooves penetrate through the outer wall of the upper cement component and are connected to the large grooves.
[0009] Preferably, each of the two small grooves is provided with a locking pin, a limit ring is provided on the outer side of the locking pin, and a handle is installed at the bottom of the outer wall of the locking pin.
[0010] Preferably, the limiting ring is disposed in the large groove, the outer side of the limiting ring is fitted with the inner side of the circular groove, and the handle is placed on the outside of the upper cement component by means of a locking pin.
[0011] Preferably, a lower cement component is provided at the bottom of the outer wall of the cement cylinder, and scale strips are provided on both sides of the outer wall of the cement cylinder. A first-level slot, a second-level slot, and a third-level slot are provided on both the left and right sides of the outer wall of the cement cylinder. The first-level slot, the second-level slot, and the third-level slot are arranged vertically on the side of the outer wall of the cement cylinder, and the distance between the slots is the same, which is 100mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by installing a sliding bar, a sliding block, a T-slot, and a limiting block, achieves directional and stable sliding and anti-detachment limiting for adjusting the size of cement components. This prevents the cement components from detaching from the assembly track during the sliding process, ensures the structural stability of the cement components during adjustment, reduces component damage caused by sliding misalignment, extends service life, and solves the problem that some existing cement components cannot be adjusted in size or are prone to sliding deviation during size adjustment, resulting in cement component sizes not meeting construction requirements or component damage. 2. This utility model, by installing a locking pin, a limiting ring, and a multi-level locking groove, enables precise adjustment of the overall length of the cement component in multiple positions according to actual construction needs. The locking pin and the locking groove achieve stable fixation after adjustment. Moreover, the operation is convenient and efficient, and the multi-position design can adapt to the size requirements of different scenarios. The fixed structure is firm and not easy to loosen, which solves the problem that the size of existing cement components cannot be flexibly adjusted or the fixation is unstable after adjustment, making it difficult to adapt to diverse construction scenarios.

[0018] Please see Figure 4 , Figure 6 and Figure 7 An embodiment of this utility model is provided: an adjustable-size cement component, in which two small grooves 6 are provided with locking pins 8, and a limiting ring 9 is provided on the outer side of the locking pin 8. The limiting ring 9 is provided in the large groove 7, and the outer side of the limiting ring 9 is fitted with the circular inner side of the large groove 7. The handle 10 is placed on the outside of the upper cement component 1 through the locking pins 8. The limiting ring 9 on the outer wall of the locking pin 8 is limited in the large groove 7 to prevent the locking pin 8 from falling out of the small grooves 6. Furthermore, the operator first inserts the locking pin 8 into the cement component 1 through the small groove 6. The locking pin 8 passes through the small groove 6 and enters the large groove 7. The middle and bottom outer walls of the locking pin 8 are provided with threads. The threaded groove on the inner wall of the limiting ring 9 is engaged with the thread in the middle of the locking pin 8, and the limiting ring 9 is fixed in the middle of the locking pin 8. The outer side of the handle 10 is provided with a circular threaded groove. The operator then fixes the handle 10 to the bottom through the thread on the outer wall of the locking pin 8, and then pulls the handles 10 on both sides outward until the locking pin 8 can no longer be observed directly above the cement component 1.
[0019] Please see Figure 2 , Figure 3 and Figure 4 The present invention provides an embodiment of an adjustable-size cement component, wherein a first sliding strip 2 is fitted with the vertical groove of a first T-shaped groove 16, a first sliding block 3 is fitted with the horizontal groove of the first T-shaped groove 16, the first T-shaped groove 16 is composed of a vertical groove and a horizontal groove, a second sliding strip 4 is fitted with the vertical groove of a second T-shaped groove 17, and a second sliding block 5 is fitted with the horizontal groove of the second T-shaped groove 17. The first T-shaped groove 16 and the second T-shaped groove 17 are provided on the outer side of the cement cylinder 12, and a first limiting block 18 and a second limiting block 19 are provided at the top of the outer wall of the cement cylinder 12. Furthermore, after the operator installs the two locking pins 8 on the left and right sides of the upper cement component 1, the operator lifts the upper cement component 1 and aligns the first slider 3 and the second slider 5 on both sides of the inner wall of the upper cement component 1 with the first T-groove 16 and the second T-groove 17 in the cement cylinder 12. Then, the operator slowly lowers the upper cement component 1, so that the first slider 3 on one side of the upper cement component 1 is engaged in the horizontal groove of the first T-groove 16, and the first slide bar 2 is engaged in the vertical groove of the first T-groove 16. At the same time, the second slider 5 on the other side of the cement component is engaged in the horizontal groove of the second T-groove 17, and the second slide bar 4 is engaged in the vertical groove of the second T-groove 17. This causes the upper cement component 1 to slowly move downward along the first T-groove 16 and the second T-groove 17 in the cement cylinder 12 until the upper cement component 1 contacts the top of the outer wall of the lower cement component 11.
[0020] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 An embodiment of this utility model is provided: an adjustable-size cement component, wherein two large grooves 7 are provided on the inner side of the upper cement component 1, and two small grooves 6 are provided on the outer side of the upper cement component 1. The two small grooves 6 penetrate through the outer wall of the upper cement component 1 and are connected to the large grooves 7. Each of the two small grooves 6 is provided with a locking pin 8. A limit ring 9 is provided on the outer side of the locking pin 8, and a handle 10 is installed at the bottom of the outer wall of the locking pin 8. Furthermore, when the bottom of the outer wall of the upper cement component 1 and the top of the outer wall of the lower cement component 11 are in contact with each other, the operator aligns the two screw holes in the first limiting block 18 with the two screw holes at the top of the outer wall of the cement cylinder 12, and screws the bolt 20 into the screw holes to fix the first limiting block 18 directly above the first T-slot 16. The operator then aligns the two screw holes in the second limiting block 19 with the two screw holes at the top of the outer wall of the cement cylinder 12, and tightens the bolt 20 through the screw holes to fix the second limiting block 19 directly above the second T-slot 17. Then the operator presses the handles 10 on both sides of the outer wall of the upper cement component 1 inward to insert the locking pin 8 into the first-level locking groove 13.
[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 The present invention provides an embodiment of an adjustable-size cement component. The cement cylinder 12 has a primary slot 13, a secondary slot 14, and a tertiary slot 15 on both the left and right sides of its outer wall. The primary slot 13, secondary slot 14, and tertiary slot 15 are arranged vertically on the outer side of the cement cylinder 12. The distance between the slots is the same, which is 100mm. When fixing the cement component 1, the locking pin 8 is inserted into the corresponding slot according to different situations. Furthermore, after the operator installs the upper cement component 1 and the lower cement component 11 together, the locking pin 8 is inserted into the first-level locking groove 13, preventing the upper cement component 1 and the lower cement component 11 from sliding relative to each other. At the same time, the bottom of the outer wall of the upper cement component 1 is in contact with the top of the outer wall of the lower cement component 11. The cement cylinder 12 has scale strips on both sides of its outer wall. The two scale strips are respectively located next to the first T-slot 16 and the second T-slot 17, with scale values from 0mm to 200mm. When the cement component needs to be lengthened by 100mm, the operator first pulls the handles 10 on both sides of the outer wall of the upper cement component 1 outwards, pulls the locking pin 8 out of the first-level locking groove 13, then lifts the upper cement component 1, observes that the scale strip reaches a height of 100mm and stops, and presses the handles 10 on both sides inwards, so that the locking pin 8 is locked into the second-level locking groove 14. When the cement component needs to be lengthened by 200mm, the operator first pulls out the handles 10 on both sides of the outer wall of the upper cement component 1, pulls out the locking pin 8 from the first-level locking groove 13, lifts the upper cement component 1, and stops when the scale bar reaches a height of 200mm. Then, the handles 10 on both sides are pressed inward so that the locking pin 8 is locked into the third-level locking groove 15, thus completing the size adjustment of the cement component.
[0022] Working principle: During initial assembly, the operator first fits the upper cement component 1 into the T-groove on the outer wall of the cement cylinder 12 through the inner wall slide bar and slider to ensure that the upper cement component 1 can slide stably along the T-groove. Then, the first limiting block 18 and the second limiting block 19 are fixed to the top of the cement cylinder 12 with bolts 20 to prevent the upper cement component 1 from falling out when it slides. When adjusting the size, the operator first pulls the handle 10, which causes the locking pin 8 to be pulled out of the first-level locking groove 13. The limiting ring 9 on the outer wall of the locking pin 8 is limited in the large groove 7 to prevent the locking pin 8 from falling out of the small groove 6. Then, the upper cement component 1 is lifted upwards. Referring to the scale strip on the outer wall of the cement cylinder 12, the operator stops after reaching the target length. An increase of 100mm corresponds to the second-level locking groove 14, and an increase of 200mm corresponds to the third-level locking groove 15. Finally, the operator presses the handle 10 to make the locking pin 8 engage with the corresponding slot and fix it, thus fixing the upper cement component 1 and the cement cylinder 12, and achieving precise adjustment of the overall component size.
[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
