DETAILED DESCRIPTION

[0032] The present application will now be described more fully hereinafter with reference to the accompanying drawings, in which currently preferred embodiments of the application are shown. The application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and fully convey the scope of the application to those skilled in the art.

[0033] A small connecting reinforcing device for an assembled wall and a support member, such as Figure 1 and Figure 2As shown, including the first mounting member 1, the second mounting member 2, the fixing lug 3 and the adjusting mechanism 4, the first mounting member 1 is common two, the first mounting member 1 is used for mounting on the fabricated wall, the first mounting member 1 rear is rotatably connected with the second mounting member 2 for connecting the support member, the first mounting member 1 and the second mounting member 2 left and right sides are connected with the fixing lug 3 for fixed installation, the first mounting member 1 is equipped with the adjusting mechanism 4 for quickly adjusting the rotation support angle of the second mounting member 2.

[0034] It should be noted that when installing the support member on the fabricated wall, the support member needs to be supported and installed by connecting the reinforcing device, first, the first mounting member 1 is installed on the fabricated wall through the fixing lug 3 by bolt, then the support angle of the second mounting member 2 is adjusted by controlling the adjusting mechanism 4, so that the top of the second mounting member 2 can be fitted with the bottom of the support member, finally the fixing lug 3 on the second mounting member 2 is installed by using bolt, so that the second mounting member 2 is connected and fixed with the support member.

[0035] As shown in Figure 1 and Figure 3 The adjusting mechanism 4 includes a lead screw 41, a first sliding member 42, a connecting rod 43 and a second sliding member 44, the first mounting member 1 is rotatably connected with the lead screw 41, the front side of the lead screw 41 is hexagonal prism structure, which is convenient for construction personnel to use tools to quickly adjust the lead screw 41, the first sliding member 42 is threadedly connected with the lead screw 41, the first sliding member 42 is slidably connected with the adjacent first mounting member 1, the first sliding member 42 is guided by the first mounting member 1 during sliding, the second sliding member 44 is slidably connected with the second mounting member 2, the second sliding member 44 is guided by the second mounting member 2 during sliding, the connecting rod 43 is rotatably connected between the first sliding member 42 and the second sliding member 44.

[0036] It needs to be explained that, due to the different specifications of the shape of the bottom of the support, when the support is installed on the fabricated wall, the angle between the support and the fabricated wall exists in the specification difference, and the traditional installation accessory is difficult to directly adapt to the change of the angle, at this time, the screw rod 41 can be rotated according to the angle between the support and the fabricated wall, so that the screw rod 41 drives the first sliding piece 42 to slide, the sliding of the first sliding piece 42 drives the connecting rod 43 to rotate, and then the second sliding piece 44 slides, and the second mounting piece 2 is supported and rotated through the second sliding piece 44, so that the second mounting piece 2 starts to adjust the angle, and then the second mounting piece 2 can quickly fit the bottom of the support to complete the adaptive reinforcement connection. It needs to be specially pointed out that, when the device is carried, the bottom of the second mounting piece 2 can be made to fit the top of the adjacent first mounting piece 1 through the rotation of the screw rod 41 to complete the folding, which is convenient for carrying and transporting. In summary, the first sliding piece 42 slides through the rotation of the screw rod 41, so that the connecting rod 43 drives the second sliding piece 44 to slide, and the second mounting piece 2 quickly adjusts the angle, and then adapts to the angle between the support and the fabricated wall, realizes the effect of quick reinforcement connection, and at the same time, adjusting the screw rod 41 can make the first mounting piece 1 and the second mounting piece 2 completely fit, which is convenient for carrying and transporting.

[0037] As Figure 1 , Figure 4 , Figure 5 and Figure 6 It also includes an extension mechanism 5, the extension mechanism 5 includes a mounting frame 51, an extension piece 52, a first rack 53, a mounting seat 54, a first spur gear 55, a rotating shaft 56, an inner wheel 57, an outer wheel 58, a scroll spring 59, a first fixing piece 510 and a pull rope 511, there are two mounting frames 51, two extension pieces 52 for extending the support width are symmetrically connected on the mounting frame 51 in an upper and lower manner, the non-adjacent sides of the two upper extension pieces 52 are respectively connected with the inner sides of the second mounting pieces 2, the non-adjacent sides of the two lower extension pieces 52 are respectively connected with the inner sides of the first mounting pieces 1, the first racks 53 are connected to the inner sides of the rear parts of the first mounting pieces 1, the mounting seats 54 are bolted to the left and right two front sides of the lower mounting frame 51, the rotating shafts 56 are rotatably connected between the mounting seats 54 and the mounting frame 51, the first spur gears 55 are connected to the rear sides of the rotating shafts 56 and mesh with the adjacent first racks 53, the inner wheels 57 are rotatably connected to the rotating shafts 56, the outer wheels 58 are rotatably connected to the inner wheels 57, the scroll springs 59 are connected between the inner wheels 57 and the adjacent outer wheels 58, and the inner wheels 57 can drive the outer wheels 58 to rotate synchronously after rotating a certain angle, the first fixing pieces 510 are bolted to the left and right two front sides of the upper mounting frame 51, the pull ropes 511 are connected between the first fixing pieces 510 and the adjacent outer wheels 58, and the lower parts of the pull ropes 511 are wound around the corresponding outer wheels 58.

[0038] It should be noted that in order to improve the support stability of the device to the support piece, and at the same time increase the support area, the first mounting piece 1 and the second mounting piece 2 can be extended by the extension mechanism 5, thereby increasing the support area of the first mounting piece 1 and the second mounting piece 2 while improving the stability of the support. In operation, by directly pulling the first mounting piece 1 and the second mounting piece 2 to slide to the side away from each other, the corresponding extension piece 52 can be driven to slide and extend in the corresponding mounting frame 51, thereby increasing the spacing between the second mounting pieces 2. At the same time, the spacing part is supported by the mounting frame 51 and the extension piece 52 to enhance the support of the support piece, and to avoid the lack of support at the bottom of the support piece in the spacing part. It should be particularly noted that during the carrying process of the device, the second mounting piece 2 is first required to be attached to the first mounting piece 1 by rotating the lead screw 41, but eventually there may still be a gap between the first mounting piece 1 and the second mounting piece 2. At this time, the first mounting piece 1 and the second mounting piece 2 can be slid to the side close to each other to close, so that the first mounting piece 1 drives the corresponding first rack 53 to move to the side close to each other. The first rack 53 will be in contact and engaged with the corresponding first spur gear 55 during movement, and the first rack 53 will drive the first spur gear 55 to rotate during continuous movement, thereby causing the shaft 56 to drive the inner wheel 57 to rotate. The inner wheel 57 will cause the volute spring 59 to deform under stress during rotation, and the outer wheel 58 will rotate synchronously after the inner wheel 57 rotates by a certain angle, thereby winding the pull rope 511. At this time, the pull rope 511 will pull the first fixing piece 510 downward, thereby causing the mounting frames 51 to move close to each other, and allowing the first mounting piece 1 and the second mounting piece 2 to completely adhere to each other. As described above, by pulling the first mounting piece 1 and the second mounting piece 2, the extension piece 52 is extended to both sides under the guidance of the mounting frame 51, thereby increasing the support area of the first mounting piece 1 and the second mounting piece 2 and improving the support effect. At the same time, during the carrying process of the device, the first mounting piece 1 and the second mounting piece 2 are pushed close to each other, so that the first rack 53 drives the first spur gear 55 to rotate, thereby causing the inner wheel 57 to drive the outer wheel 58 to rotate and wind the pull rope 511. Finally, the mounting frames 51 are attached to each other, thereby completely adhering the first mounting piece 1 and the second mounting piece 2 to each other, improving the convenience of carrying.

[0039] As Figure 1 and Figure 7As shown, the first synchronization mechanism 6 comprises a bevel gear set 61, a connecting shaft 62, a bearing seat 63, a mounting frame 64 and a handle 65, the mounting frame 64 is connected to the front side of the mounting frame 51 by bolts, the handle 65 is rotatably connected to the front side of the mounting frame 64, the handle 65 is provided with a non-slip sleeve for convenient operation by the construction personnel, the bearing seat 63 is connected to the front side of the first mounting member 1 by bolts, the connecting shaft 62 which passes through the bearing seat 63 is slidably connected to the inside of the handle 65, the connecting shaft 62 is rotatably connected to the adjacent bearing seat 63, the bevel gear set 61 is connected between the connecting shaft 62 and the adjacent lead screw 41, the bevel gear set 61 is composed of two bevel gears which cooperate with each other, one bevel gear is connected to the front end of the corresponding lead screw 41, and the other bevel gear is connected to the non-adjacent end of the connecting shaft 62, and the adjacent bevel gears are meshed with each other.

[0040] It should be noted that when the construction personnel need to adjust the rotation of the lead screw 41, in order to avoid the inconsistency of the rotation angle of the two lead screws 41, the handle 65 can be directly rotated, so that the handle 65 drives the connecting shaft 62 to rotate, and then the bevel gear set 61 is rotated, and when the bevel gear set 61 starts to rotate, the lead screw 41 is synchronously rotated, thereby avoiding the inconsistency of the rotation angle of the two lead screws 41. It should be particularly noted that when the first mounting member 1 moves away from each other, the connecting shaft 62 will slide away from each other under the drive of the bearing seat 63, thereby adapting to the distance between the first mounting member 1. In summary, by rotating the handle 65, the connecting shaft 62 is rotated, thereby driving the corresponding lead screw 41 to rotate synchronously, thereby avoiding the inconsistency of the rotation angle of the lead screw 41 during rotation, and the angle between the second mounting member 2 and the first mounting member 1 is consistent.

[0041] As shown in Figure 1 , Figure 8 and Figure 9 , the second synchronization mechanism 7 comprises a fixed shaft 71, a second spur gear 72 and a second rack 73, the fixed shaft 71 is connected to the rear side of the mounting frame 51, the second spur gear 72 is rotatably connected to the fixed shaft 71, and the second rack 73 is connected to the rear side of the extension member 52 and is meshed with the second spur gear 72.

[0042] It should be noted that when the extension pieces 52 slide towards each other, as the extension piece 52 on one side starts to move, it drives the corresponding second rack 73 to move, so that the second spur gear 72 starts to rotate, and then the second rack 73 on the other side moves towards the side, and then the extension piece 52 realizes synchronous contraction movement. In summary, through the sliding of the extension piece 52 on one side, the synchronous contraction movement of the extension pieces 52 on both sides can be realized under the cooperation of the second spur gear 72 and the second rack 73, the adjustment efficiency is improved, and the inconsistent adjustment of the extension width on both sides is avoided.

[0043] As shown in Figure 1 and Figure 10 Further include a protection mechanism 8, the protection mechanism 8 includes a second fixing piece 81 and a protection frame 82, the first mounting piece 1 front is connected with the second fixing piece 81 through the bolt, and the second fixing piece 81 is rotatably connected with the protection frame 82 for shielding the components.

[0044] It should be noted that in order to avoid the damage of the bevel gear set 61 on the front side of the first mounting piece 1, the components are shielded by the protection frame 82 in the daily state, and when the components need to be overhauled and debugged, the protection frame 82 is rotated to the side not adjacent to open.

[0045] As shown in Figure 1 and Figure 11 Further include a locking mechanism 9, the locking mechanism 9 includes a fixed column 91, a third mounting piece 92 and a clamping piece 93, the second fixing piece 81 front side is connected with the fixed column 91, the second mounting piece 2 front side is connected with the third mounting piece 92, the third mounting piece 92 is rotatably connected with the clamping piece 93 for locking the adjacent fixed column 91, and the lower part of the clamping piece 93 is arc structure.

[0046] It should be noted that when the first mounting piece 1 and the second mounting piece 2 are attached, the clamping piece 93 can be rotated to make the clamping piece 93 and the corresponding fixed column 91 clamped, so that the first mounting piece 1 and the second mounting piece 2 are locked, and the stability between the first mounting piece 1 and the second mounting piece 2 is improved.
