[0004] The length of the base in the above patent document is constant. When multiple bases need to be spliced together for use, adhesives or screw-nut fixing parts are required. The viscosity of the adhesive will decrease after a long time, and the screw-nut fixing parts not only need to rely on special tools, but may also rotate automatically after long-term use, resulting in loosening. Summary of the Utility Model

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of clear description and are not used to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationships shall also be regarded as the scope of implementation of the present utility model without substantial change in the technical content.

[0026] Refer to Figures 1 - 7, a steel bar fixing seat for a two-way slab formwork with splicing function, comprising a C-shaped base 1 and a V-shaped bracket 2. Both ends of the bracket 2 are welded to the inner bottom wall of the base 1. U-shaped installation grooves 3 are provided at both the left and right ends of the base 1. A U-shaped plug 4 is horizontally slidably arranged in one of the installation grooves 3. The plug 4 is locked by a locking component. The locking component includes a spring rod 10 and a plug rod 11 fixedly installed on the inner bottom wall of the base 1. A pull plate is fixedly installed at the top end of the spring rod 10. The plug rod 11 is fixedly installed on the lower surface of the pull plate. Two locking grooves 12 for the insertion of the end of the plug rod 11 are provided on the surface of the plug 4. A through port communicating with one of the installation grooves 3 is provided on the inner bottom wall of the base 1. The plug rod 11 passes through the through port.

[0027] Oblique walls 5 are provided at both top ends of the plug 4 near the notch of the installation groove 3. Locking ports 6 are symmetrically provided on the upper surface of the plug 4. Slide rods 7 are symmetrically and vertically arranged in the installation groove 3 away from the plug 4. A triangular locking block 8 is fixedly installed at the bottom end of the slide rod 7. A telescopic spring 9 is sleeved on the slide rod 7. Both ends of the telescopic spring 9 are fixedly connected to the surface of the locking block 8 and the groove wall of the installation groove 3 respectively. Through ports are symmetrically provided on the top wall of the installation groove 3 away from the plug 4. The top ends of the two slide rods 7 correspond to the positions of the two through ports respectively. The two locking blocks 8 are controlled to move vertically together by a connecting component. The connecting component includes a connecting rod 15. Slide openings are symmetrically and vertically provided on the groove walls of the installation groove 3 away from the plug 4. Both ends of the connecting rod 15 pass through the two slide openings respectively and are fixedly connected to the surfaces of the two locking blocks 8.

[0028] In the initial state, the plug 4 is located in the installation groove 3 and is not exposed, which can improve the overall aesthetics of the base 1. When multiple bases 1 need to be spliced, first, control the pull plate to move upward to stretch the spring rod 10, and the bottom end of the plug rod 11 is removed from one of the locking grooves 12, so as to release the locking of the plug 4. Then, control the plug 4 to move out of the installation groove 3 until it moves to a position corresponding to the bottom end of the plug rod 11 and another locking groove 12. At this time, release the pull plate, and the plug rod 11 will quickly move downward and reset under the elastic potential energy of the spring rod 10 and insert into this locking groove 12, thus completing the locking of the plug 4.

[0029] Then, control the insertion block 4 to align with the installation groove 3 opened on the side wall of another base 1 where no insertion block 4 is provided and push it in. During the pushing process, the two inclined walls 5 of the insertion block 4 will respectively slide in contact with the inclined surfaces of the two locking blocks 8 in the installation groove 3. Under the action of the inclined surface pressing, the two locking blocks 8 and the two sliding rods 7 will both move upward, and the two telescopic springs 9 will contract together until the insertion block 4 can no longer move. At this time, the two locking ports 6 on the upper surface of the insertion block 4 will respectively correspond to the positions of the two locking blocks 8, and the pressing force applied by the insertion block 4 to the locking blocks 8 disappears. The two locking blocks 8 will then move downward and reset under the elastic potential energy of the two telescopic springs 9 and respectively enter the two locking ports 6, thus completing the splicing, which is convenient and fast.

[0030] When it is necessary to release the splicing, the connecting rod 15 can be controlled to move upward, so that the two locking blocks 8 move upward together until the two locking blocks 8 are respectively removed from the two locking ports 6.

[0031] A limiting groove 13 is horizontally opened at the bottom of one of the installation grooves 3, and a limiting block 14 is fixedly installed on the lower surface of the insertion block 4. The limiting block 14 is slidably arranged in the limiting groove 13.

[0032] The limiting block 14 can only slide in the limiting groove 13, which can limit the moving distance of the insertion block 4 and prevent the insertion block 4 from being removed from the installation groove 3.

[0033] A limiting component is provided in the base 1. The limiting component is used to limit the upward movement of the connecting rod 15. The limiting component includes an L-shaped limiting plate 16. A rotating shaft is horizontally rotatably installed in the base 1, and the limiting plate 16 is fixedly sleeved on the rotating shaft. Torsion springs 17 are symmetrically sleeved on the rotating shaft, and the two ends of the torsion springs 17 are respectively fixedly connected to the limiting plate 16 and the base 1.

[0034] In the initial state, the limiting plate 16 will be in a vertical state under the elastic potential energy of the torsion spring 17, and its surface will be located above the connecting rod 15. At this time, the connecting rod 15 is blocked by the limiting plate 16 and cannot move upward, so the two sliding rods 7 and the two locking blocks 8 cannot move upward either. This can prevent the two sliding rods 7 from being affected by external forces and driving the two locking blocks 8 to move vertically during the splicing of multiple bases 1, resulting in the two locking blocks 8 being respectively removed from the two locking ports 6 and further causing the splicing to fail.

[0035] When it is necessary to control the two locking blocks 8 to move upward, the limiting plate 16 can be rotated so that the limiting plate 16 rotates to no longer be located above the connecting rod 15. Then, the blocking of the limiting plate 16 on the connecting rod 15 disappears. Then, control the connecting rod 15 to move upward to make the two locking blocks 8 move upward.

[0036] In the present utility model, in the initial state, the insertion block 4 is located within the installation groove 3 and is not exposed, thereby improving the overall aesthetics of the base 1. When multiple bases 1 need to be spliced, first, the locking assembly is unlocked from the insertion block 4. Then, the insertion block 4 is controlled to move out of the installation groove 3. Next, the locking assembly is used to lock the insertion block 4 again. The insertion block 4 is controlled to be aligned with the installation groove 3 provided on the side wall of another base 1 without the insertion block 4 and is pushed in. During the pushing process, the two inclined walls 5 of the insertion block 4 will respectively slide in contact with the inclined surfaces of the two locking blocks 8 within the installation groove 3. Under the action of the inclined surface pressure, both the two locking blocks 8 and the two slide bars 7 will move upward, and the two telescopic springs 9 will contract together until the insertion block 4 can no longer move. At this time, the two locking ports 6 on the upper surface of the insertion block 4 will respectively correspond to the positions of the two locking blocks 8. The pressing force exerted by the insertion block 4 on the locking blocks 8 disappears, and the two locking blocks 8 will move downward and reset under the elastic potential energy of the two telescopic springs 9 and respectively enter the two locking ports 6, thus completing the splicing, which is convenient and fast, avoiding the cumbersome steps of using screw and nut fasteners, and also avoiding the defect that the viscosity decreases after a long time and the splicing part becomes loose when using adhesives.

[0037] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "coupling", "fixation" and the like shall be understood in a broad sense.

[0038] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
