Description

Technical Field

[0001] The present invention relates to the technical field of scaffolding, and in particular to a socket structure of a socket - type scaffolding. Background Art

[0002] The socket - type scaffolding is a common scaffolding for building construction. Its structure is mainly composed of vertical poles, horizontal bars and socket connectors. Through the socket connectors, a stable structure is formed, which can bear large loads. The socket - type scaffolding can also be freely adjusted in height and layout according to construction needs to adapt to various construction environments. When installing the pins of the socket - type scaffolding, in order to ensure safety and stability, a hammer is usually used to tap to enhance the fixation of the pins.

[0003] In the prior art, most of the socket connectors are fixedly connected to the vertical poles by welding and are not detachable. Different - diameter vertical poles need to be matched with different socket connectors, which is very troublesome. In different construction sites, the connection heights of the horizontal bars or diagonal bars to the vertical poles may be different. Since the positions of the socket connectors are fixed, vertical poles with socket connectors of different heights or additional socket connectors need to be added, which is rather inconvenient. Moreover, the socket connectors are inserted into the fastener heads of the horizontal bars or diagonal bars through pins, and there is no further fixing device. When erecting the scaffolding, during the process of workers passing and taking parts, it is very easy for the rod - shaped parts to touch and knock the erected scaffolding. Multiple touches and knocks cause vibrations to the socket pins of the scaffolding, and the pins will become loose under the influence of external forces. At the same time, when the scaffolding shakes during use, the pins will also become loose, thus affecting their fixed state and further reducing the stability of the scaffolding and increasing the risk of collapse. Summary of the Invention

[0004] The purpose of the present invention is to provide a socket structure of a socket - type scaffolding to solve the problems raised in the above - mentioned background art.

The plurality of convex plates correspond to the plurality of avoiding grooves of the adjacent locking blocks one by one, and the convex plates are slidably connected with the corresponding avoiding grooves.

[0011] Further, the convex plates abut against the outer wall of the vertical rod. A plurality of locking screws are threadedly connected along the circumferential direction on the outer side of the annular groove. The ends of the locking screws abut against the corresponding locking blocks. A circular hole is formed through the middle of the driving plate. A plurality of driving rings are fixedly arranged along the circumferential direction on the outer side of the circular hole. The columns are movably connected with the driving rings.

[0012] Further, a rotating member is fixedly arranged at one end of the driving plate far away from the disc.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] In the following description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. The term "connection" only represents the connection between devices and has no special meaning.

[0032] In addition, as long as there is no conflict between the technical fields and installation methods involved in the embodiments of the present invention described below, they can be combined with each other.

[0033] Specific embodiment: Please refer to Figures 1 - 10, A socket structure of a button - and - loop type scaffolding, comprising a support assembly 1, two groups of clamping assemblies 2, and a plurality of locking assemblies 3. The support assembly 1 includes a locking disc 11. The locking disc 11 is arranged in the middle or at the end of the vertical pole 4 in the button - and - loop type scaffolding. The two groups of clamping assemblies 2 are symmetrically arranged at the upper and lower ends of the locking disc 11. Each group of clamping assemblies 2 includes two driving plates 23 arranged at intervals and a plurality of locking blocks 21. The plurality of locking blocks 21 are arranged circumferentially between the two driving plates 23 and are movably connected to the driving plates 23. Adjacent two locking blocks 21 are slidably connected. An accommodation hole 117 is vertically penetrated through the inside of the locking disc 11. The vertical pole 4 is inserted or sleeved in the accommodation hole 117. The locking block 21 abuts against the outer wall of the vertical pole 4. A disc 12 is arranged on the outer side of the middle part of the locking disc 11. The cross - bar 5 in the button - and - loop type scaffolding is inserted into the disc 12 and is tightly connected through the locking assembly 3.

[0034] Furthermore, the voids formed by enclosing the middle parts of the plurality of locking blocks 21 constitute a locking cavity. The vertical pole 4 is inserted into the locking cavity, and the inner wall of the locking cavity abuts against the outer wall of the vertical pole 4. The arranged clamping assembly 2 and the locking disc 11 cooperate, and can be installed on vertical poles 4 with different diameters, having greater applicability. Different numbers of locking discs 11 can also be installed according to the number and position of the cross - bars 5, and cross - bars 5 or diagonal bars at different heights can be connected as needed without the need to replace the vertical pole 4 separately, which is very convenient. If the height of the vertical pole 4 is not enough, the locking disc 11 can also connect two vertical poles 4 together to increase the construction height, and the disassembly is also relatively convenient, greatly improving the construction efficiency.

[0035] Furthermore, the locking assembly 3 includes a plug - pin member 31 and a pressing plate 33. A baffle 312 is fixedly arranged at the upper end of the plug - pin member 31. A plug rod 311 is fixedly connected to the lower surface of the plug. Two opposite outer surfaces of the lower end of the plug rod 311 are respectively provided with clamping slots 314, and the other two opposite outer surfaces of the lower end of the plug rod 311 are respectively provided with positioning slots 313. A jack is penetrated through the middle part of the pressing plate 33. Positioning blocks 336 are fixedly arranged on the surfaces at both ends of the jack. The positioning blocks 336 are inserted into and slidably connected to the positioning slots 313. The pressing plate 33 is inserted into the lower part of the plug rod 311 through the jack and is connected in cooperation with the clamping slots 314 through a pawl 332.

[0036] Furthermore, annular grooves 112 are respectively arranged at the upper and lower ends of the accommodation hole 117. The locking blocks 21 and the driving plates 23 are both arranged in the annular grooves 112. The driving plates 23 are coaxially arranged with the locking disc 11, and the surfaces of the driving plates 23 in contact with the annular grooves 112 are rotatably connected.

[0037] Further, a plurality of grooves 113 are circumferentially formed in the middle of the accommodation hole 117. A pressing block 13 is slidably arranged in the groove 113. Both the upper and lower ends of the pressing block 13 are inclined surfaces, which facilitates the vertical rod 4 to press the pressing block 13 when passing through the locking cavity. An anti-slip rubber is arranged on the surface of the pressing block 13 close to the vertical rod 4. A plurality of sliding grooves 115 are formed on both sides of the groove 113. A plurality of sliding plates 131 are fixedly arranged on both surfaces of the pressing block 13. The plurality of sliding plates 131 correspond to the plurality of sliding grooves 115 one by one, and the sliding plates 131 are slidably connected with the corresponding sliding grooves 115. A plurality of pressing springs 114 are arranged between the inner surface of the pressing block 13 and the bottom of the groove 113. The outer surface of the pressing block 13 abuts against and is slidably connected with the outer wall of the vertical rod 4.

[0038] Further, sliding grooves 116 are formed on both the upper and lower surfaces of the annular groove 112. Columns 214 are fixedly arranged on both the upper and lower surfaces of the locking block 21. Sliders 215 are fixedly arranged at the ends of the columns 214. The sliders 215 are slidably connected with the sliding grooves 116. A plurality of avoiding grooves 213 are spacedly formed on one surface of the locking block 21. A plurality of convex plates 212 are spacedly and fixedly arranged on the other surface. The plurality of convex plates 212 correspond to the plurality of avoiding grooves 213 of the adjacent locking block 21 one by one, and the convex plates 212 are slidably connected with the corresponding avoiding grooves 213. This setting can also increase the anti-slip effect on the surface of the vertical rod 4.

[0039] Further, the convex plate 212 abuts against the outer wall of the vertical rod 4. A plurality of convex blocks 16 are fixedly arranged on the inner wall of the annular groove 112 along the circumference. The convex blocks 16 extend towards the outside of the locking block 21. A threaded hole 161 is formed through the surface of the convex block 16 facing the locking block 21. The axial direction of the threaded hole 161 is parallel to the direction of the corresponding sliding groove 116. A locking screw 18 is connected in the threaded hole 161 by a thread. The end of the locking screw 18 abuts against the corresponding locking block 21. A circular hole 231 is formed through the middle of the driving plate 23. A plurality of driving rings 232 are fixedly arranged on the outside of the circular hole 231 along the circumference. The column 214 is arranged in the driving ring 232 and is movably connected with the driving ring 232. Locking through holes 111 are formed through both the upper and lower surfaces of the annular groove 112. The vertical rod 4 passes through the locking through holes 111 and then enters the locking cavity.

[0040] Further, a rotating member 22 is fixedly arranged at one end of the driving plate 23 away from the disc 12. A plurality of connecting columns 221 are arranged on the surface of the rotating member 22 close to the driving plate 23 along the circumferential direction. A plurality of avoiding holes 118 are penetrated through the outer sides of the upper and lower surfaces of the locking disc 11 along the circumferential direction. The plurality of connecting columns 221 correspond to the plurality of avoiding holes 118 one by one. The connecting column 221 is slidably connected with the corresponding avoiding hole 118. One end of the connecting column 221 close to the disc 12 passes through the avoiding hole 118 and is fixedly connected with the outer walls of the corresponding two driving plates 23. The outer wall of the connecting column 221 is slidably connected with the inner wall of the annular groove 112. By driving the driving plate 23 to rotate through the rotating member 22, and then driving the locking block 21 to move through the driving plate 23, the size of the locking cavity is changed. The moved locking block 21 is tightened by the locking screw 18, so that the locking block 21 can clamp the vertical rod 4 to prevent relative sliding between the locking disc 11 and the vertical rod 4.

[0041] Further, mounting grooves 334 are formed on both surfaces of the insertion hole of the pressing plate 33. An unlocking block 331 is slidably arranged in the mounting groove 334. A sliding hole 333 is penetrated through the upper surface of the mounting groove 334. The upper end of the unlocking block 331 is arranged in the sliding hole 333 and is slidably connected with the sliding hole 333. A pawl 332 is fixedly arranged on one surface of the unlocking block 331 close to the clamping groove 314. A plurality of return springs 335 are arranged between the surface of the unlocking block 331 away from the pawl 332 and the bottom surface of the mounting groove 334. When the pressing plate 33 moves upward, each time the pawl 332 passes through a tooth of the clamping groove 314, the return spring 335 will contract correspondingly. If the pressing plate 33 moves in the reverse direction, the tooth of the clamping groove 314 will block the pawl 332. At this time, by pulling the unlocking block 331 to separate the pawl 332 from the clamping groove 314, the pressing plate 33 can move in the reverse direction. The arranged plug-in member 31 and the pressing plate 33 are mutually matched and clamped, so that the fastener head can be locked to prevent the plug-in member 31 from loosening. At the same time, it can also adapt to fastener heads of different lengths, increase the stability of the scaffold, and reduce the risk of collapse.

[0042] Further, a plurality of first connection holes 121 and a plurality of second connection holes 122 are arranged at intervals along the circumferential direction on the surface of the disc 12. The plurality of first connection holes 121 and the plurality of second connection holes 122 are alternately arranged at intervals in sequence. The fastener head at the end of the cross bar 5 is inserted into the first connection hole 121. The upper surface of the accommodating block abuts against the lower surface of the fastener head. The lower surface of the pressing plate 33 abuts against the upper surface of the fastener head. The second connection hole 122 is used for connecting the inclined rod. The installation method of the fastener head of the inclined rod is the same as that of the cross bar 5. At the same time, in order to prevent relative sliding between the convex plate 212 of the locking block 21 and the surface of the vertical rod 4, a locking groove corresponding to the convex plate 212 can be formed on the surface of the vertical rod 4 to make the connection more stable.

[0043] When a socket structure of a socket - type scaffolding is in use and the locking socket 11 needs to be installed in the middle of the vertical pole 4, the locking socket 11 is passed through the vertical pole 4. When the end of the vertical pole 4 contacts the inclined surface of the abutting block 13, as the vertical pole 4 is inserted, the abutting spring 114 contracts, and the abutting block 13 slides into the groove 113, making the space between multiple abutting blocks 13 larger until the vertical pole 4 passes through. After the locking socket 11 is passed through to the required position, the rotating member 22 is rotated. The rotating member 22 rotates, driving the driving plate 23 to rotate. The driving plate 23 drives the locking block 21 to move until the convex plate 212 of the locking block 21 abuts against the outer wall of the vertical pole 4. Then the locking screw 18 is rotated, and the locking screw 18 moves until the end of the locking screw 18 abuts against the corresponding locking block 21. At this time, the locking socket 11 is firmly connected to the vertical pole 4. Similarly, the locking socket 11 is installed on other vertical poles 4. When it is necessary to connect the cross - bar 5 or the diagonal bar to the vertical pole 4, the fastener head of the cross - bar 5 or the diagonal bar is inserted into the disc 12, and the fastener hole on the fastener head is aligned with the corresponding first connection hole 121 or the second connection hole 122. The plug rod 311 of the plug - pin member 31 passes through the fastener hole and the connection hole, and the lower surface of the baffle 312 abuts against the upper surface of the fastener head. Then the pressing plate 33 is inserted from the lower end of the plug rod 311. The pressing plate 33 slides upward until the upper surface of the pressing plate 33 abuts against the lower surface of the fastener head. The pressing plate 33 is self - locked under the cooperation of the ratchet 332 and the clamping groove 314. The pressing plate 33 and the baffle 312 cooperate to lock the fastener head. At this time, the connection between the cross - bar 5 or the diagonal bar and the vertical pole 4 is completed;

[0044] When the locking socket 11 needs to connect two vertical poles 4, the opposite ends of the two vertical poles 4 are simultaneously inserted into the locking socket 11. The ends of the two vertical poles 4 abut in the middle of the receiving hole 117. Then the rotating member 22 is rotated so that the locking blocks 21 at both ends of the locking socket 11 respectively abut against the outer walls of the corresponding vertical poles 4. The locking screw 18 is rotated to tighten the locking block 21. At this time, the two - section vertical pole 4 is connected. When it is necessary to disassemble the cross - bar 5 or the diagonal bar, only the unlocking block 331 needs to be pushed outwards. The unlocking block 331 drives the ratchet 332 to separate from the clamping groove 314, and the plug rod 311 separates from the pressing plate 33. Then the plug - pin member 31 can be taken out. When disassembling the vertical pole 4, only the abutting screw needs to be rotated in the reverse direction. When the device is in use, the set locking socket 11 can be freely combined on the vertical pole 4, and can be assembled with the cross - bar 5 and the diagonal bar into a scaffolding of different shapes and sizes, more freely adjusting the height and layout of the scaffolding. At the same time, with the cooperation of the clamping assembly 2 and the locking assembly 3, the installation and disassembly of the scaffolding are also faster and more convenient, improving work efficiency.
