DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 The utility model provides a technical solution: a pier column reinforcement cage positioning and fixing device that is easy to adjust, including: an installation shell 1, a pier column reinforcement cage base 2, a worm 3, a worm wheel 4, a sawtooth 5, a drive ring 6, a limit block 7, a fixing block 8, a hinged rod 9, an extrusion block 10, a rubber pad 11, a mounting block 12, a threaded rod 13, a sleeve 14, a protrusion 15, an outer connecting block 16, an inner connecting block 17, a clamping block 18 and a spring 19.

[0029] When using the easily adjustable pier column reinforcement cage positioning and fixing device, first Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the mounting housing 1 is sleeved and mounted on the outer side of the pier column reinforcement cage base 2, the outer end of the worm 3 penetrates and extends out of the outer side of the mounting housing 1, and the side of the worm 3 is meshedly connected with the worm wheel 4, and the worm 3 and the worm wheel 4 are both rotatably connected in the internal cavity of the mounting housing 1, the sawtooth 5 is fixedly mounted on the inner side of the driving ring 6, and the sawtooth 5 is meshed with the worm wheel 4 for transmission, the driving ring 6 is rotatably connected to the inside of the mounting housing 1, the limit block 7 is fixedly mounted on the outer side of the driving ring 6, and the limit block 7 is arranged in an annular shape at equal angles along the center point of the mounting housing 1;

[0030] The installation shell 1 is sleeved on the outside of the pier column reinforcement cage base 2 and its position is adjusted, and then the worm 3 is rotated to rotate the worm wheel 4. The worm wheel 4 rotates and meshes with the saw teeth 5, thereby driving the driving ring 6 to rotate inside the installation shell 1. The driving ring 6 drives the limit block 7 on its outside to slide in the groove opened inside the installation shell 1, thereby limiting the stable rotation of the driving ring 6. Two groups of worm 3 and worm wheel 4 are arranged along the central axis of the installation shell 1 to improve the stability of the position of the driving ring 6. The worms 3 on both sides need to cooperate to rotate the driving ring 6, so that the driving ring 6 is not easily moved due to accidental touch;

[0031] The limit block 7 and the fixed block 8 are arranged in a group, and the fixed block 8 is fixedly installed on the inner side of the installation shell 1, the outer side of the fixed block 8 is rotatably connected with a hinge rod 9, and the other end of the hinge rod 9 is rotatably connected with an extrusion block 10, the outer end of the extrusion block 10 extends into the interior of the installation shell 1, and the extrusion block 10 is slidably connected to the inner side of the installation shell 1, and a rubber pad 11 is fixedly installed on the inner end surface of the extrusion block 10, and the extrusion block 10 and the rubber pad 11 are both arranged in an arc-shaped structure;

[0032] When the driving ring 6 rotates, it drives the fixed block 8 to move. The fixed block 8 pushes the hinge rod 9 to swing. The other end of the hinge rod 9 pushes the extrusion block 10 to move towards the direction of the pier reinforcement cage matrix 2 until the rubber pad 11 fits on the outside of the pier reinforcement cage matrix 2 and then stops rotating the worm 3. At this time, the pier reinforcement cage matrix 2 is firmly fixed and positioned in the middle of the installation housing 1, which is convenient for the normal use of the pier reinforcement cage matrix 2 and avoids the adverse effects caused by its displacement.

[0033] As Figure 1 , Figure 3 and Figure 4 shown, the installation block 12 is fixedly installed inside the installation housing 1, and both the threaded rod 13 and the sleeve 14 are installed inside the installation block 12. A convex block 15 is fixedly installed on the outside of the sleeve 14, and both the sleeve 14 and the convex block 15 are slidably connected inside the installation block 12. The threaded rod 13 is rotatably connected to the inside of the sleeve 14, and an outer connecting block 16 and an inner connecting block 17 are respectively fixedly installed at the outer end of the sleeve 14;

[0034] The installation housing 1 is respectively fixedly sleeved on the outside of two sections of the pier reinforcement cage matrix 2. Then, rotate the two threaded rods 13 to make the sleeve 14 slowly slide out from inside the installation housing 1. The convex block 15 restricts the moving direction of the sleeve 14 to remain stable. At this time, the outer connecting block 16 and the inner connecting block 17 are in contact;

[0035] The structure of the outer connecting block 16 is in a "C" - shaped structure, and the inner connecting block 17 is slidably connected inside the outer connecting block 16. The clamping block 18 is slidably connected inside the inner connecting block 17, and the clamping blocks 18 are symmetrically arranged inside the inner connecting block 17. The clamping blocks 18 are connected by a spring 19. The outer end of the clamping block 18 is snap - connected to the outer connecting block 16, and the front end of the clamping block 18 extends to the outside of the inner connecting block 17;

[0036] Press the front sides of the two clamping blocks 18 to make the clamping blocks 18 move towards each other. The spring 19 undergoes elastic deformation. When the inner connecting block 17 enters the inside of the outer connecting block 16, release the clamping blocks 18. Under the elastic action of the spring 19, the clamping blocks 18 snap - fit into the inside of the outer connecting block 16, completing the connection between the outer connecting block 16 and the inner connecting block 17, further completing the connection between two adjacent installation housings 1, restricting the positions of the two pier reinforcement cage matrices 2 to be on the same horizontal line, facilitating the installation of the pier reinforcement cage matrix 2 and the pier reinforcement cage matrix 2, avoiding their displacement, and facilitating stable use.
