Self-locking disc-lock scaffolding node connection structure

Abstract

This utility model discloses a self-locking disc-type scaffolding node connection structure, including a scaffolding vertical rod. A connecting disc is sleeved on the surface of the scaffolding vertical rod, and a snap-fit ​​connector is inserted into the surface of the connecting disc. A scaffolding horizontal rod is fixedly connected to the outer end of the snap-fit ​​connector. A self-locking mechanism is provided inside the snap-fit ​​connector, and a limit mechanism and a pushing mechanism are provided at the lower end of the self-locking mechanism. This utility model, by having the scaffolding horizontal rod drive the snap-fit ​​connector to be inserted into the surface of the connecting disc, can limit the inclined surface of the pin to abut against the connecting disc. When compressed, it will retract into the fixed frame. When the inner wall of the snap-fit ​​connector abuts against the surface of the connecting disc, the elastic force of the first spring can push the limit plate and the limit pin to reset and insert into the connecting disc, facilitating quick self-locking between the connecting disc and the snap-fit ​​connector.

Description

Technical Field

[0001] This utility model relates to the field of scaffolding connector technology, and in particular to a self-locking disc-lock scaffolding node connection structure. Background Technology

[0002] Disc-lock scaffolding is a new type of construction scaffolding system. With its unique structural design and connection method, it has been widely used in modern construction. Disc-lock scaffolding is a temporary support system composed of uprights, horizontal bars, diagonal bars and other components connected by discs. It has the characteristics of structural stability and flexible erection.

[0003] Existing disc-lock scaffolding uses pins to secure the discs, which requires a significant amount of time to install multiple discs, reducing installation efficiency. Furthermore, the installation process relies on tools, which is inconvenient. Therefore, we propose a self-locking disc-lock scaffolding node connection structure to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a self-locking disc-lock scaffolding node connection structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The self-locking disc-type scaffolding node connection structure includes a scaffolding vertical rod, a connecting disc sleeved on the surface of the scaffolding vertical rod, and a snap-fit ​​connector inserted into the surface of the connecting disc. A scaffolding horizontal rod is fixedly connected to the outer end of the snap-fit ​​connector. A self-locking mechanism is provided inside the snap-fit ​​connector, and a limit mechanism and a pushing mechanism are provided at the lower end of the self-locking mechanism.

[0007] Preferably, the self-locking mechanism includes a fixed frame, which is fixedly connected above the snap-fit ​​connector. The inner wall of the fixed frame is welded to one end of the first spring, and the other end of the first spring is welded to one side of the limiting plate. A limiting pin is fixedly connected to the other side of the limiting plate.

[0008] Preferably, the inner wall size of the fixed frame is adapted to the surface size of the limiting plate, the limiting plate is fixedly connected to both sides of the limiting plate, and the fixed frame is provided with strip-shaped through grooves adapted to the limiting sliders on both sides.

[0009] Preferably, the card connector has a through hole inside that matches the limiting pin, and the surface of the limiting pin is set as an inclined surface.

[0010] Preferably, the limiting mechanism includes a hinge plate, and the bottom end of the limiting pin is provided with grooves on both sides, and the hinge plate is hinged in the groove. A counterweight is glued to the outside of the hinge plate, and the side of the counterweight is set as an arc surface.

[0011] Preferably, the pushing mechanism includes a second spring, the inner wall of the groove has a recessed hole, and one end of the second spring is welded to the recessed hole. The other side of the second spring is welded to one end of the connecting column, and the other end of the connecting column is fixedly connected to the pushing plate.

[0012] Preferably, there are two symmetrically arranged connecting columns, and both connecting columns are cylindrical.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device inserts the clamping connector onto the surface of the connecting plate by driving the scaffold crossbar. The inclined surface of the limiting pin abuts against the connecting plate. When squeezed, it retracts into the fixed frame. When the inner wall of the clamping connector abuts against the surface of the connecting plate, the elastic force of the first spring can push the limiting plate and the limiting pin to reset and insert into the connecting plate, which facilitates quick self-locking between the connecting plate and the clamping connector.

[0015] 2. During the process of the device penetrating the connecting plate through the limiting pin, the hinge plate is compressed and folds inside the limiting pin. After the limiting pin is penetrated, the elastic force of the second spring allows the connecting column to drive the push plate to push the hinge plate, facilitating the unfolding of the two hinge plates. This makes it easier to limit the limiting pin between itself and the connecting plate, preventing the limiting pin from loosening. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-4 The self-locking disc-type scaffolding node connection structure includes a scaffolding vertical rod 1, a connecting disc 2 sleeved on the surface of the scaffolding vertical rod 1, and a snap-fit ​​connector 3 inserted into the surface of the connecting disc 2. A scaffolding horizontal rod 4 is fixedly connected to the outer end of the snap-fit ​​connector 3. A self-locking mechanism 5 is provided inside the snap-fit ​​connector 3, and a limit mechanism 6 and a pushing mechanism 7 are provided at the lower end of the self-locking mechanism 5. The limit mechanism 6 and the pushing mechanism 7 can prevent the self-locking mechanism 5 from loosening.

[0026] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the self-locking mechanism 5 includes a fixed frame 51. The fixed frame 51 is fixedly connected to the top of the snap-fit ​​connector 3. The inner wall of the fixed frame 51 is welded to one end of the first spring 52. The other end of the first spring 52 is welded to one side of the limiting plate 53. Through the elastic force of the first spring 52, the limiting plate 53 and the limiting pin 54 can be easily pushed to reset. The limiting pin 54 is fixedly connected to the other side of the limiting plate 53. Through the limiting pin 54 passing through the connecting plate 2 and the snap-fit ​​connector 3, the connecting plate 2 and the snap-fit ​​connector 3 can be limited and connected.

[0027] Furthermore, refer to Figure 2 It can be seen that the inner wall size of the fixed frame 51 is adapted to the surface size of the limiting plate 53. The limiting plate 53 adapts to the inner wall of the fixed frame 51, which can play the role of limiting and guiding the limiting pin 54. Limiting sliders 55 are fixedly connected to both sides of the limiting plate 53. The fixed frame 51 has strip-shaped through grooves adapted to the limiting sliders 55 on both sides. When the limiting plate 53 moves along the inside of the fixed frame 51, the limiting sliders 55 can slide along the strip-shaped through grooves, which can play the role of limiting and guiding the limiting plate 53. At the same time, when the connecting plate 2 and the snap-fit ​​connector 3 are disassembled, the limiting sliders 55 can be moved to retract the limiting pin 54 into the fixed frame 51, which facilitates the disassembly between the connecting plate 2 and the snap-fit ​​connector 3.

[0028] Furthermore, refer to Figure 3 and Figure 4It can be seen that the inside of the snap connector 3 is provided with a through hole that matches the limiting pin 54. The limiting pin 54 can be easily passed through the through hole in the snap connector 3. The surface of the limiting pin 54 is set as an inclined surface. When the inclined surface is squeezed, the limiting pin 54 can retract into the fixed frame 51.

[0029] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the limiting mechanism 6 includes a hinge plate 61. The bottom end of the limiting pin 54 has grooves on both sides, and the hinge plate 61 is hinged in the groove. The hinge plate 61 can be easily moved by hinged installation. A counterweight 62 is glued to the outside of the hinge plate 61, and the side of the counterweight 62 is set as an arc surface. The counterweight 62 can increase the counterweight of the hinge plate 61, and the arc surface of the side of the counterweight 62 can guide and prevent jamming.

[0030] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the pushing mechanism 7 includes a second spring 71, a recessed hole is provided on the inner wall of the groove, and one end of the second spring 71 is welded to the recessed hole. The other side of the second spring 71 is welded to one end of the connecting column 72, and the other end of the connecting column 72 is fixedly connected to the pushing plate 73. Through the elastic force of the second spring 71 itself, the connecting column 72 can push the pushing plate 73, which facilitates the unfolding of the two sets of hinge plates 61.

[0031] Furthermore, refer to Figure 3 and Figure 4 It can be seen that there are two symmetrically arranged connecting posts 72, and both connecting posts 72 are cylindrical. By making the connecting posts 72 cylindrical, wear between them and the concave holes can be reduced.

[0032] Working principle: When this utility model is in use, when the scaffolding vertical rod 1 is in use, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4By driving the scaffold crossbar 4 to fit the clamping connector 3 onto the surface of the connecting plate 2, during the insertion process of the clamping connector 3, the inclined surface of the limiting pin 54 can abut against the connecting plate 2. At this time, the limiting pin 54 will retract into the clamping connector 3 and the fixing frame 51. When the surface of the connecting plate 2 abuts against the inner wall of the clamping connector 3, the elastic force of the first spring 52 can cause the limiting plate 53 to drive the limiting pin 54 through the connecting plate 2 and the clamping connector 3. During the penetration process, the hinge plate 61 will retract into the limiting pin 54 due to the pressure of the connecting plate 2 and the clamping connector 3. After the limiting pin 54 has penetrated, the elastic force of the second spring 71 can cause the connecting column 72 to push the pushing plate 73 to reset, so that the hinge plate 61 can be unfolded and the clamping connector 3 can be limited to the surface of the connecting plate 2.

[0033] The above is the complete working principle of this utility model.
