Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a portable connecting piece of a scaffold. Background Art

[0002] Scaffolding refers to a temporary structure built on a construction site or other engineering site to support and facilitate workers in construction operations. Scaffolding can provide a stable platform so that workers can work at heights, such as wall building, plastering, demolition, maintenance, decoration and other operations. The cup-shaped multifunctional scaffolding is a new type of scaffolding with broad development prospects.

[0003] The Chinese patent with publication number CN218894385U discloses a scaffolding connector. After the annular fixing seat is set on the main pole, the screw is turned to drive the block to slide in the slide groove and abut against the outer wall of the main pole to complete the installation of the scaffolding connector. Similarly, the number and height spacing of the scaffolding connector can be determined according to actual conditions.

[0004] In the above-mentioned patent, it is necessary to tighten multiple screws in sequence to drive the abutment block to abut the outer side of the main rod to achieve fixed installation, and multiple screws need to be screwed when removing, which is cumbersome to operate. For the installation of the scaffolding, it is usually necessary to assemble a large number of connecting parts, resulting in a lot of time and energy required to complete the installation and subsequent removal of the scaffolding, which is inefficient, and the tightening degree of the four screws is difficult to be fully synchronized, thereby reducing the fixing effect and affecting the stability and safety of the connection structure. Utility Model Content

[0005] The utility model aims to provide a portable scaffolding connector which has high disassembly and assembly efficiency and good fixing effect during installation.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0007] A portable connector for scaffolding includes an annular fixing seat, an inner cavity is provided inside the annular fixing seat, a circular ring is rotatably installed inside the inner cavity, a plurality of wedge blocks are installed on the inner wall of the circular ring, a plurality of through grooves extending to the inner ring of the annular fixing seat are provided on the inner wall of the inner cavity, a guide rod is provided inside the through groove, and the plurality of guide rods correspond to the plurality of wedge blocks one by one, and an abutment block is installed at one end of the guide rod away from the wedge blocks. The outer surface of the circular ring is provided with teeth, a rotating rod is rotatably connected inside the inner cavity, and the upper end of the rotating rod extends to the outer side of the annular fixing seat, a toothed ring is sleeved on the outer surface of the rotating rod, and the toothed ring is meshed with the teeth. A shell is installed on the outer surface of the annular fixing seat, and a self-locking mechanism is provided between the interior of the shell and the outer surface of the rotating rod located outside the annular fixing seat. Four connecting seats are installed in a circumferential array on the outer surface of the annular fixing seat, a mounting seat is provided outside the connecting seat, and a connecting mechanism is provided inside the mounting seat.

[0008] It can be seen that after the annular fixing seat is put on the outside of the main rod, it is only necessary to twist the rotating rod to drive the circular ring to rotate, so that each wedge block squeezes the corresponding guide rod at the same time, and then drives multiple abutment blocks to abut on the outer surface of the main rod at the same time, and through the setting of the self-locking mechanism, the rotating rod is locked to prevent it from reversing, thereby achieving the purpose of fixed installation. Since only one operation of twisting the rotating rod is required, the speed of installation and removal can be greatly improved, and the time and energy of workers can be reduced during the installation and removal of the scaffolding, thereby improving the work efficiency, and multiple abutment blocks can maintain synchronized abutment force, thereby improving the fixing effect and ensuring the stability and safety of the connecting structure. In addition, the number of wedge blocks, guide rods and abutment blocks can be set to different groups to meet different usage conditions, and they are very portable during installation and removal.

[0009] Furthermore, the self-locking mechanism includes a telescopic rod installed on the inner wall of the housing, a top plate installed at the end of the telescopic rod, a spring sleeved on the outer surface of the telescopic rod, and the two ends of the spring respectively abut against the inner wall and the top plate of the housing. A connecting rod is connected to the outer surface of the top plate, and the end of the connecting rod passes through the outer side of the housing, and a movable arc-shaped tooth is installed at the end of the connecting rod, and a plurality of fixed arc-shaped teeth are evenly installed on the outer surface of the rotating rod, and the movable arc-shaped teeth are meshed and connected with the fixed arc-shaped teeth.

[0010] When the rotating rod is rotated counterclockwise to drive the wedge block to squeeze the guide rod, the arc surface of the fixed arc tooth and the arc surface of the movable arc tooth squeeze each other, and the force generated by the squeezing drives the movable arc tooth to drive the connecting rod to move in the direction of the telescopic rod and compress the spring, so that the rotating rod can complete the counterclockwise rotation. When the rotating rod reverses, the plane of the fixed arc tooth and the plane of the movable arc tooth abut against each other, thereby preventing the rotating rod from rotating in the opposite direction. Therefore, the purpose of automatic locking can be achieved, so that the abutment block always remains in abutment with the main rod, completing rapid fixation.

[0011] Furthermore, a through groove is provided on the outer surface of the shell, and a plug hole is provided on a side of the top plate facing the through groove.

[0012] When the scaffolding needs to be dismantled, a tool can be inserted into the through slot and inserted into the socket to drive the compression telescopic rod, thereby separating the movable arc teeth from the fixed arc teeth. At this time, the rotating rod can be rotated in the opposite direction to separate the abutment block from the main rod, thereby achieving the purpose of rapid dismantling.

[0013] Furthermore, a slot is provided on one side of the connecting seat facing the mounting seat, an insert is installed on one side of the mounting seat facing the connecting seat, a screw hole is provided on the outer surface of the insert, a bolt is installed on the outer surface of the connecting seat, and the bolt is adapted to the screw hole.

[0014] By providing the slots and the inserts, the connecting mechanism can be easily replaced when it is damaged, thereby eliminating the need to replace the entire connecting piece and reducing the cost of use.

[0015] Furthermore, a ball is provided at one end of the guide rod away from the abutment block, and the ball abuts against the wedge block.

[0016] By setting the ball, the friction resistance can be reduced and the smoothness can be improved when the ball is pressed against the shell.

[0017] Furthermore, a rubber pad is arranged on the outer surface of the abutment block, and an anti-slip pattern is formed on the outer surface of the rubber pad.

[0018] By providing the rubber pad and the anti-skid pattern, the friction with the outer surface of the main rod can be increased, thereby improving the fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The utility model is described in detail below with reference to the accompanying drawings.

The outer surface of the circular ring 102 is provided with teeth 106, a rotating rod 107 is rotatably connected inside the inner cavity 101, and the upper end of the rotating rod 107 extends to the outside of the annular fixing seat 100, a tooth ring 108 is sleeved on the outer surface of the rotating rod 107, and the tooth ring 108 is meshed with the teeth 106. The outer surface of the annular fixing seat 100 is provided with a housing 109, and a self-locking mechanism 200 is provided between the inside of the housing 109 and the outer surface of the rotating rod 107 located outside the annular fixing seat 100. Four connecting seats 110 are provided in a circumferential array on the outer surface of the annular fixing seat 100, and a mounting seat 111 is provided outside the connecting seat 110, and a connecting mechanism 112 is provided inside the mounting seat 111.

[0026] When in use, the annular fixing seat 100 is first sleeved on the outer side of the main rod, and then the rotating rod 107 is rotated counterclockwise. Through the meshing relationship between the tooth ring 108 and the tooth teeth 106, the circular ring 102 can be driven to rotate clockwise, and the wedge block 103 can squeeze the guide rod 104, driving the guide rod 104 to drive the abutment block 105 to move in the direction of the main rod until multiple abutment blocks 105 abut against the outer surface of the main rod at the same time, thereby realizing the rapid installation of the connecting piece, and through the setting of the self-locking mechanism 200, the rotating rod 107 can be locked after the abutment block 105 abuts against the outer surface of the main rod to prevent it from reversing, thereby ensuring the stability and safety of the installation, and the number and setting of the wedge block 103, the guide rod 104 and the abutment block 105 are six, seven, eight or other groups. The more the number of groups is set, the greater the contact area with the outer surface of the main rod, thereby improving the fixing effect to meet different usage requirements, and no matter how many groups are set, it is very portable and convenient to use during installation and removal.

[0027] Specifically, the self-locking mechanism 200 includes a telescopic rod 201 installed on the inner wall of the housing 109, a top plate 202 is installed at the end of the telescopic rod 201, a spring 203 is sleeved on the outer surface of the telescopic rod 201, and the two ends of the spring 203 are respectively in contact with the inner wall of the housing 109 and the top plate 202. A connecting rod 204 is connected to the outer surface of the top plate 202, and the end of the connecting rod 204 passes through the outer side of the housing 109, and a movable arc-shaped tooth 205 is installed at the end of the connecting rod 204. A plurality of fixed arc-shaped teeth 206 are evenly installed on the outer surface of the rotating rod 107, and the movable arc-shaped teeth 205 are meshed and connected with the fixed arc-shaped teeth 206. When the rotating rod 107 is rotated counterclockwise to drive the wedge block 103 to squeeze the guide rod 104, the arc surface of the fixed arc-shaped teeth 206 and the arc surface of the movable arc-shaped teeth 205 squeeze each other. The force generated by extrusion drives the movable arc-shaped tooth 205 to drive the connecting rod 204 to move in the direction of the telescopic rod 201 and compress the spring 203, so that the rotating rod 107 can complete the counterclockwise rotation. When the rotating rod 107 reverses, the plane of the fixed arc-shaped tooth 206 and the plane of the movable arc-shaped tooth 205 abut against each other, thereby preventing the rotating rod 107 from rotating in the opposite direction. Therefore, the purpose of automatic locking can be achieved, so that the abutment block 105 always remains in abutment with the main rod, completing rapid fixation.

[0028] Specifically, a through groove 300 is provided on the outer surface of the shell 109, and a socket 301 is provided on the side of the top plate 202 facing the through groove 300. When the scaffolding needs to be dismantled, a tool can be used to extend from the through groove 300 and inserted into the socket 301 to drive the compression telescopic rod 201, thereby separating the movable arc teeth 205 from the fixed arc teeth 206. At this time, the rotating rod 107 can be rotated in the opposite direction, thereby separating the abutment block 105 from the main rod, thereby achieving the purpose of rapid dismantling. The tool can be a screwdriver or other slender objects.

[0029] Specifically, a slot 400 is provided on a side of the connecting seat 110 facing the mounting seat 111, an insert block 401 is installed on the side of the mounting seat 111 facing the connecting seat 110, a screw hole 402 is provided on the outer surface of the insert block 401, a bolt 403 is installed on the outer surface of the connecting seat 110, and the bolt 403 is adapted to the screw hole 402. Through the arrangement of the slot 400 and the insert block 401, when the connecting mechanism 112 is damaged, it can be conveniently replaced, thereby eliminating the need to replace the entire connecting component, thereby reducing the cost of use.

[0030] Specifically, a ball 500 is provided at one end of the guide rod 104 away from the abutment block 105 , and the ball 500 abuts against the wedge block 103 . The arrangement of the ball 500 can reduce friction resistance and improve smoothness when the ball 500 is pressed against the housing 109 .

[0031] Specifically, the outer surface of the abutment block 105 is provided with a rubber pad, and the outer surface of the rubber pad is provided with anti-skid grooves.
