[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] The utility model proposes a scaffold reinforcement structure, comprising: a first vertical rod 1;

[0029] A crossbar support block 2 is welded on the top of the No. 1 vertical bar 1, and the No. 1 vertical bar 1 is used to support the crossbar support block 2. During assembly, the bottom end of the No. 1 vertical bar 1 can be fixed to the ground, and the crossbar support block 2 is used to support the No. 2 vertical bar 3, the No. 1 crossbar locking rack 5 and the No. 2 crossbar locking rack 6, and the crossbar support block 2 cooperates with the No. 1 crossbar locking rack 5 and the No. 2 crossbar locking rack 6 to lock one end of the crossbar 7; a No. 2 vertical bar 3 is rotatably installed in the middle position of the top of the crossbar support block 2, and the No. 2 vertical bar 3 is used to lock the No. 2 vertical bar 3 above the scaffolding. When the gear 4 rotates counterclockwise, the first crossbar locking rack 5 and the second crossbar locking rack 6 can be driven to slide toward the outside of the crossbar support block 2, and then the first crossbar locking rack 5 is locked. When the four cross bars 7 are all engaged, the second vertical bar 3 can be rotated clockwise to drive the gear 4 to rotate synchronously. When the gear 4 rotates clockwise, it can drive the locking rack 5 of the first cross bar and the locking rack 6 of the second cross bar to slide toward the inside of the cross bar support block 2. In this process, the locking rack 5 of the first cross bar and the L-shaped plate at one end of the locking rack 6 of the second cross bar will also pull The rectangular bar at one end of the cross bar 7 is embedded in the guide groove on the inner side of the cross bar support block 2, and one end of the cross bar 7 cannot shake, so that one end of the four cross bars 7 can be fixed; two No. 1 cross bar locking racks 5 and two No. 2 cross bar locking racks 6 are slidably installed on the inner side of the cross bar support block 2, and the L-shaped plates at one end of the No. 1 cross bar locking rack 5 and the No. 2 cross bar locking rack 6 are engaged with the L-shaped plate at one end of the cross bar 7 to lock the cross bar 7; four cross bars 7 are also installed on the outer side of the cross bar support block 2, and the cross bar 7 is used to support the table top used for construction work.

[0030] In the present disclosure, Figure 1 , Figure 2 and Figure 4When the four cross bars 7 are all engaged, the second vertical bar 3 can be rotated clockwise to drive the gear 4 to rotate synchronously. When the gear 4 rotates clockwise, it can drive the first cross bar locking rack 5 and the second cross bar locking rack 6 to slide toward the inside of the cross bar support block 2. In this process, the L-shaped plates at one end of the No. 1 cross bar locking rack 5 and the No. 2 cross bar locking rack 6 will also pull the rectangular rod at one end of the cross bar 7 to embed into the guide groove on the inner side of the cross bar support block 2, and one end of the cross bar 7 cannot shake, so that one end of the four cross bars 7 can be fixed.

[0031] In the present disclosure, Figure 2 , Figure 4 and Figure 5 As shown, four groups of guide grooves for sliding of the No. 1 cross bar locking rack 5 and the No. 2 cross bar locking rack 6 are arranged in a ring shape with the axis of the gear 4 as the center, and the width and height of the guide grooves are equal to the width and height of the rectangular rods on one side of the cross bar 7. Therefore, when the gear 4 is rotated, these No. 1 cross bar locking rack 5 and the No. 2 cross bar locking rack 6 can slide in the guide grooves inside the cross bar support block 2, and are relatively stable when sliding, and the rectangular rods on one side of the cross bar 7 will not shake after being embedded in these guide grooves.

[0032] In the present disclosure, Figure 6 As shown, the tooth grooves on the No. 1 crossbar locking rack 5 and the No. 2 crossbar locking rack 6 are both engaged with the gear 4, and when the gear 4 rotates, it can drive the No. 1 crossbar locking rack 5 and the No. 2 crossbar locking rack 6 to move synchronously. When the gear 4 rotates, the positions of the No. 1 crossbar locking rack 5 and the No. 2 crossbar locking rack 6 can be adjusted, thereby being able to loosen or lock one end of the crossbar 7.

[0033] In the present disclosure, Figure 6 As shown, the No. 1 crossbar locking rack 5 and the No. 2 crossbar locking rack 6 are arranged alternately up and down, and the No. 1 crossbar locking rack 5 is located at the upper position, and the No. 2 crossbar locking rack 6 is located at the lower position. Therefore, the No. 1 crossbar locking rack 5 and the No. 2 crossbar locking rack 6 will not collide when they are driven by the gear 4 to slide synchronously, thereby avoiding conflict.

[0034] In the present disclosure, Figure 1-Figure 4When the first and second cross bar locking racks 5 and 6 slide toward the inside of the cross bar support block 2, the L-shaped plates at one end thereof will pull the rectangular rods at one end of the cross bar 7 into the guide grooves on the inside of the cross bar support block 2, thereby all the ends of the four cross bars 7 can be fixed.

[0035] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6 When the gear 4 rotates counterclockwise, the first and second crossbar locking racks 5 and 6 can be driven to slide toward the outside of the crossbar support block 2, and then the L-shaped plates at one end of the No. 1 crossbar locking rack 5 and the No. 2 crossbar locking rack 6 will extend outward through the openings on the crossbar support block 2, making it easy for the L-shaped plate at one end of the crossbar 7 to engage with the L-shaped plates at one end of the No. 1 crossbar locking rack 5 and the No. 2 crossbar locking rack 6, and the rectangular plates at the bottom of these openings can play an auxiliary supporting role for the No. 1 crossbar locking rack 5 and the No. 2 crossbar locking rack 6 to prevent them from falling outward.

[0036] When the gear 4 rotates counterclockwise, it can drive the locking rack 5 of the No. 1 cross bar 5 and the locking rack 6 of the No. 2 cross bar 6 to slide toward the outside of the cross bar support block 2, and then the L-shaped plates at one end of the locking rack 5 of the No. 1 cross bar 5 and the locking rack 6 of the No. 2 cross bar 6 will extend outward. At this time, the L-shaped plate at one end of the cross bar 7 can be engaged with the L-shaped plate at one end of the locking rack 5 of the No. 1 cross bar or the locking rack 6 of the No. 2 cross bar, and the four cross bars can be connected. After the cross bars 7 are all engaged, the second vertical bar 3 can be rotated clockwise to drive the gear 4 to rotate synchronously. When the gear 4 rotates clockwise, it can drive the first cross bar locking rack 5 and the second cross bar locking rack 6 to slide toward the inside of the cross bar support block 2. In this process, the L-shaped plates at one end of the first cross bar locking rack 5 and the second cross bar locking rack 6 will also pull the rectangular rod at one end of the cross bar 7 to embed into the guide groove on the inner side of the cross bar support block 2, and one end of the cross bar 7 will not be able to shake, so that one end of the four cross bars 7 can be fixed, and the cross bar 7 will not shake during use;

[0037] When it is necessary to disassemble the cross bar 7, the No. 2 vertical bar 3 can be rotated counterclockwise to drive the gear 4 to rotate synchronously. When the gear 4 rotates counterclockwise, it can drive the No. 1 cross bar locking rack 5 and the No. 2 cross bar locking rack 6 to slide toward the outside of the cross bar support block 2, and then the No. 1 cross bar locking rack 5 and the No. 2 cross bar locking rack 6 The L-shaped plate at one end will extend outward. At this time, the L-shaped plate at one end of the cross bar 7 can be separated from the No. 1 cross bar locking rack 5 or the L-shaped plate at one end of the No. 2 cross bar locking rack 6, so that the cross bar 7 can be disassembled.
