[0030] 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.

[0031] Reference Figure 1-Figure 2 The utility model provides an embodiment: a reinforcement structure for a steel grid frame, including a mounting ball 1, which is connected and installed by connecting and installing multiple groups of mounting balls 1 with multiple groups of steel rods 2 to form a steel grid frame. The inner wall of the mounting ball 1 is plugged with steel rods 2, and four groups of steel rods 2 are provided. The steel rods 2 are plugged into the mounting ball 1 and then welded so that the steel rods 2 can be fixedly installed on the mounting ball 1. The outer wall of the mounting ball 1 is provided with a protective component 3. The protective component 3 is used to protect the welding points between the steel rods 2 and the mounting ball 1 to prevent rainwater from eroding the welding points, and at the same time, it can prevent the lever 44 from being accidentally touched. The outer wall of the mounting ball 1 is provided with a reinforcing component 4. The reinforcing component 4 is used to facilitate rapid reinforcement of the steel rods 2 and improve the working efficiency of the steel grid frame.

[0032] Reference Figure 2 and Figure 3The protection component 3 includes a protection cover 31, and the protection cover 31 is symmetrically distributed in two groups, which is convenient for protecting the welding points around the installation ball 1. The right side of the protection cover 31 is hinged with a hinge rod 33, and the hinge rod 33 is symmetrically distributed in two groups. Through the movement effect of the two groups of hinge rods 33, the two groups of protection covers 31 are driven to move vertically respectively. The right end of the hinge rod 33 is hinged with a movable ring 34, and the inner wall of the movable ring 34 is slidably connected with a fixed rod 36. Through the sliding effect of the movable ring 34, the two groups of hinge rods 33 are driven to move at the same time. The bottom of the protection cover 31 is fixedly connected with a guide rod 32, and the fixing effect of the guide rod 32 prevents the guide rod 32 from falling off. A guide hole 38 is opened at the top of the installation ball 1.

[0033] Reference Figure 4 and Figure 5 The reinforcement component 4 includes an arc block 41, and the inner wall of the arc block 41 is elastically connected with a clamping block 43 through a spring 42. Through the elastic force of the spring 42, the clamping block 43 always maintains a clamping effect with the clamping groove 45 when not affected by external force, thereby limiting the steel rod 2. The top of the clamping block 43 is fixedly connected with a lever 44. Two groups of clamping blocks 43 and springs 42 are symmetrically distributed on each group of arc blocks 41, and a clamping groove 45 is opened on the outer wall of the steel rod 2.

[0034] Reference Figure 2 and Figure 3 The front inner wall of the movable ring 34 is threadedly connected with a bolt 35. By screwing the bolt 35, the bolt 35 and the threaded hole 37 are threadedly connected or disconnected. A threaded hole 37 is provided on the front of the fixing rod 36. There are two groups of threaded holes 37. The two groups of threaded holes 37 are threadedly connected with the bolt 35 at different positions, thereby limiting the movable ring 34 at different positions. The outer wall of the bolt 35 is threadedly connected with the inner wall of the threaded hole 37. The threaded connection effect of the bolt 35 and the threaded hole 37 allows the fixing rod 36 to limit the movable ring 34.

[0035] Reference Figure 2 The outer periphery of the guide rod 32 is slidably connected to the inner wall of the guide hole 38. The sliding effect of the guide rod 32 guides the protective cover 31 to prevent the protective cover 31 from shifting during movement. The left end of the fixed rod 36 is fixedly connected to the right end of the arc block 41. A fixed rod 36 is provided on one group of the arc blocks 41. The fixing effect of the fixed rod 36 prevents the fixed rod 36 from falling off.

[0036] Reference Figure 4The outer wall of the arc block 41 is fixedly connected to the outer wall of the mounting ball 1. The fixing effect of the arc block 41 prevents the arc block 41 from falling off. One end of the spring 42 is fixedly connected to the inner wall of the arc block 41. The other end of the spring 42 is fixedly connected to the outer wall of the clamping block 43. The fixing effect of the spring 42 keeps the clamping block 43 fixed to prevent the clamping block 43 from falling off.

[0037] Reference Figure 2 There are four groups of arc blocks 41, which are distributed in a circular array along the installation ball 1 as the center. By providing four groups of arc blocks 41, it is convenient to reinforce the four groups of steel rods 2. The outer wall of the lever 44 is slidably connected to the top inner wall of the arc block 41, and the sliding effect of the lever 44 drives the block 43 to slide.

[0038] Reference Figure 4 The outer wall of the block 43 is slidably connected to the inner wall of the arc block 41. Through the sliding effect of the block 43, the block 43 and the slot 45 are engaged or released. The outer wall of the block 43 is engaged with the inner wall of the slot 45. Through the engagement effect of the block 43 and the slot 45, the arc block 41 limits the steel rod 2.

[0039] Working principle: When the steel rod 2 needs to be installed on the mounting ball 1, the staff loosens the bolt 35 so that the fixed rod 36 releases the limiting effect on the movable ring 34, and slides the movable ring 34 to the left along the outer circumference of the fixed rod 36, so that the two groups of hinged rods 33 respectively drive the two groups of protective covers 31 to move vertically and away from each other. By tightening the bolt 35 in the reverse direction and limiting the movable ring 34 at the same time, the two groups of protective covers 31 remain in a fixed open state.

[0040] The staff member moves the lever 44 so that the block 43 squeezes the spring 42 and moves to the inner wall of the arc block 41, and inserts the steel rod 2 into the inner wall of the mounting ball 1. The staff member releases the lever 44 so that the block 43 is engaged with the slot 45 under the elastic force of the spring 42, thereby limiting the position of the steel rod 2 and keeping it fixed. The staff member welds the connection between the steel rod 2 and the mounting ball 1 so that the steel rod 2 remains fixedly installed on the mounting ball 1. In the above manner, four groups of steel rods 2 are all installed on the mounting ball 1.

[0041] When the steel rod 2 is installed, the staff releases the limiting effect of the movable ring 34 and moves the movable ring 34 to the right, so that the hinged rod 33 drives the protective cover 31 to move towards the installation ball 1 until it fits with the outer wall of the installation ball 1. By limiting the movable ring 34, the protective cover 31 remains fixed, and the welding part of the installation ball 1 and the steel rod 2 is protected. At the same time, the lever 44 is protected to prevent others from accidentally touching the lever 44.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
