The disc buckle 100 is sleeved on the single top rod 40 through the through hole 111, and the through hole 111 and the single top rod 40 are in clearance fit. The axis of the single ejector rod 40 coincides with the preset axis O, and a plurality of mounting holes 41 are formed in the single ejector rod 40 along the length direction of the single ejector rod 40, the mounting holes 41 are arranged at intervals, and the size of the mounting holes is matched with that of the plug pin 50. The plug 50 extends into the mounting hole 41 and can be abutted against the bottom of the disc buckle 100 to prevent the disc buckle 100 from moving downwards. Since the through hole 111 is in clearance fit with the single top bar 40, when the disc buckle 100 is mounted on the single top bar 40, the disc buckle 100 can move along the length direction of the single top bar 40, so that the position of the disc buckle 100 relative to the single top bar 40 is adjusted to adjust the height of the disc buckle 100. When the scaffold is built, the disc buckles 100 are connected with the horizontal rods which are horizontally arranged, and the two ends of each horizontal rod are respectively arranged on the different disc buckles 100, so that the relative positions of the two adjacent single ejector rods 40 are limited. Therefore, when the scaffold is constructed, the weight of the cross bar is borne by the disc fastener 100, and the disc fastener 100 can be prevented from moving upwards, so that the disc fastener 100 has stability in the length direction of the single post 40 when the scaffold is constructed.

Referring to fig. 2 and 3, some embodiments of the present application provide a support structure 200 including a disc buckle 100 and a single lift pin 40, wherein the disc buckle 100 can move along the length direction of the single lift pin 40 and can fix the disc buckle 100 to the single lift pin 40 at a proper position. The disc buckle 100 includes a main body 10, a fixing member 20, and a locking assembly 30. The main body 10 has a predetermined axis O, the main body 10 has a through hole 111, the through hole 111 penetrates through two ends of the main body 10, and the axis of the through hole 111 coincides with the predetermined axis O. The main body 10 is sleeved on the single ejector rod 40 through the through hole 111, so that the axis of the single ejector rod 40 is also overlapped with the preset axis O, and the through hole 111 is in clearance fit with the single ejector rod 40, so that the movable space 14 is formed between the main body 10 and the single ejector rod 40. The fixing member 20 includes a fixing portion 21 and a connecting portion 22, the connecting portion 22 is disposed on one side of the fixing portion 21, the fixing portion 21 is disposed on one side of the single post rod 40, and at least a portion of the fixing portion 21 extends into the movable space 14 and can abut against the single post rod 40 and the through hole 111 to fill the movable space 14 between the main body 10 and the single post rod 40, so as to tightly clamp the main body 10 and the single post rod 40, and to define a relative position between the main body 10 and the single post rod 40. The locking assembly 30 is located between the main body 10 and the fixing member 20, the locking assembly 30 presses the connecting portion 22 toward the main body 10, and the locking assembly 30 presses the main body 10 toward the connecting portion 22, so that the connecting portion 22 and the main body 10 move toward each other, and the fixing portion 21 can be pushed to extend into the movable space 14, so as to block the fixing portion 21 from separating from the main body 10.

The fixing member 20 extends into the movable space 14 and can abut against the single top bar 40 and the through hole 111, so that the horizontal shaking between the single top bar 40 and the main body 10 caused by the existence of the movable space 14 can be alleviated, and the movable space 14 abuts against the single top bar 40 and the through hole 111 through the fixing member 20 to limit the relative position of the main body 10 and the single top bar 40. This also means that the direction in which the main body 10 moves upward relative to the single lift pin 40 is also defined. In transporting the support structure 200, the main body 10 can be stably transported even without separating the main body 10 from the single lift pins 40, and it is possible to reduce the occurrence of a situation in which the main body 10 slides with respect to the single lift pins 40 or even the main body 10 collides with a transport vehicle, which may be a truck, in transporting the support structure 200. Because the main body 10 does not need to be separated from the single ejector rod 40 during transportation, and the main body 10 does not need to be separated from the single ejector rod 40 specially during scaffold disassembly, the speed of scaffold disassembly can be increased, the main body 10 does not need to be reinstalled and the position of the main body 10 does not need to be adjusted when the scaffold is built next time, and the installation efficiency is high. In addition, since the main body 10 and the single lift pin 40 are fixed by being pressed against each other by the fixing member 20, it is not necessary to limit the position of the main body 10 by the mounting hole 41 of the single lift pin 40, and therefore the main body 10 can be mounted at any position in the longitudinal direction of the single lift pin 40, and the height of the main body 10 mounted on the single lift pin 40 can be adjusted steplessly.

The fixing member 20 may be positioned above the main body 10 and extend into the activity space 14 from the upper side to the lower side to realize the fixing of the main body 10 to the single lift pin 40.

Alternatively, in some embodiments, the fixing member 20 is located below the main body 10 and extends into the activity space 14 from the bottom to the top to realize the fixing of the main body 10 to the single lift pin 40.

Alternatively, in some embodiments, the number of the fixing members 20 is two, and the two fixing members 20 are oppositely arranged along the preset axis O. It is to be understood that the number of the fixing members 20 is not limited to two, but may be one, three, four, etc. When the number of the fixing members 20 is one, the axis of the single knock rod 40 is not coincident with the preset axis O. The number of locking assemblies 30 can be the same as the number of fixing members 20, so that each locking assembly 30 abuts against one fixing member 20, or the number of locking assemblies 30 can be different from the number of fixing members 20, for example, the number of locking assemblies 30 is one, and a plurality of fixing members 20 can be simultaneously pushed to move towards the activity space 14.

The outer surface 212 is disposed obliquely with respect to the inner surface 211, and the outer surface 212 gradually approaches toward the predetermined axis O in a downward and upward direction. When the fixing portion 21 extends into the movable space 14 from the bottom to the top, the inner surface 211 of the fixing portion 21 is attached to the side wall of the single lift rod 40, and the inner wall of the through hole 111 presses against the outer surface 212. Since the outer surface 212 is inclined, when the outer surface 212 contacts the inner wall of the through hole 111, a component force toward the predetermined axis O is generated, thereby increasing a frictional force between the inner surface 211 and the single lift pin 40, and the fixing part 21 is connected to the main body 10 by the locking assembly 30, so that the main body 10 can be stably mounted to the single lift pin 40.

Referring to fig. 7, optionally, in other embodiments, the outer surface 212 and the wall of the through hole 111 are both inclined with respect to the predetermined axis O and have the same slope. Since the slope of the outer surface 212 is consistent with that of the hole wall of the through hole 111, the contact area between the outer surface 212 and the hole wall of the through hole 111 can be increased, thereby improving the stability of the fixing portion 21 and the body 10.

Optionally, in some embodiments, the inner surface 211 is provided with saw teeth 23 (as shown in fig. 4), and the saw teeth 23 contact with the side wall of the single lift pin 40, so as to increase the friction between the side wall of the single lift pin 40 and the inner surface 211 by increasing the surface roughness of the inner surface 211, thereby further increasing the stability of the main body 10 mounted on the single lift pin 40.

Referring to fig. 8, optionally, in some embodiments, a friction layer 24 is disposed between the inner surface 211 and the single top bar 40, and the friction coefficient of the friction layer 24 is greater than that of the inner surface 211, so that the friction force between the friction layer 24 and the sidewall of the single top bar 40 is greater than that between the inner surface 211 and the sidewall of the single top bar 40 under the same conditions. The friction layer 24 can be elastically deformed, when the fixing portion 21 extends toward the movable space 14, the inner surface 211 and the side wall of the single lift pin 40 continuously press the friction layer 24 by the pushing of the outer surface 212, the friction layer 24 is elastically deformed, and pressure is applied to the side wall of the single lift pin 40, so that the friction force between the friction layer 24 and the side wall of the single lift pin 40 is further increased, and the stability of the main body 10 mounted on the single lift pin 40 is improved. Optionally, the friction layer 24 is made of rubber.

The position of the locking assembly 30 can be substantially defined in the horizontal direction by providing the first coupling hole 221 and the second coupling hole 131 to block the locking assembly 30 from being directly separated from the main body 10 and the fixing member 20. The first connection hole 221 and the second connection hole 131 are in clearance fit with the pressing element 31, so that the pressing element 31 can move more smoothly in the first connection hole 221 and the second connection hole 131.

In some embodiments, when the locking assembly 30 defines the relative position of the fixing member 20 and the main body 10, a space is left between the connecting portion 22 and the limiting portion 13. Because the connecting portion 22 and the limiting portion 13 are spaced apart from each other, when the fixing portion 21 is worn and thinned due to repeated use for a long time, the depth of the fixing portion 21 extending into the activity space 14 can be increased, so that the fixing portion 21 can still stably support the side wall of the single post rod 40 and the hole wall of the through hole 111. The locking assembly 30 can also correspondingly adjust the positions of the connecting portion 22 and the limiting portion 13, for example, when the locking assembly 30 is a bolt and a nut, after the depth of the fixing portion 21 extending into the movable space 14 is increased, the position of the nut relative to the bolt can be correspondingly adjusted, so that the locking assembly 30 can stably limit the positions of the main body 10 and the fixing member 20.

In other embodiments, when the locking assembly 30 defines the relative position of the fixing member 20 and the main body 10, the connecting portion 22 contacts the limiting portion 13.

In summary, the supporting structure 200 provided in the embodiment of the present invention utilizes the movable space 14 formed by the clearance fit between the through hole 111 and the single lift rod 40 to extend at least a part of the fixing portion 21 into the movable space 14, and make the fixing portion 21 press against the side wall of the single lift rod 40 and the hole wall of the through hole 111, and then limit the relative position of the main body 10 and the fixing member 20 through the locking assembly 30, so that the disc buckle 100 can be stably fixed on the single lift rod 40, and the position of the disc buckle 100 relative to the single lift rod 40 can be arbitrarily adjusted.

Embodiments of the present application also provide a template frame comprising a support structure and a cross bar. One end of the cross bar is connected with the plate buckle of one support structure, and the other end is connected with the plate buckle of the other support structure, so that a plurality of support structures can be connected with each other to form the template frame.

In addition, those skilled in the art should realize that the above embodiments are illustrative only and not limiting to the present application, and that suitable changes and modifications to the above embodiments are within the scope of the disclosure of the present application as long as they are within the true spirit and scope of the present application.
