Description

Technical Field

[0001] The utility model relates to the technical field of aerial work platforms, in particular to a guardrail upright pole locking structure. Background Art

[0002] Today's aerial work platforms are generally built with various fasteners and steel pipes. The usual pole-type scaffolding is composed of columns, crossbars, guardrails and springboards. Referring to the structure in Chinese invention patent application CN104372935A, fasteners are also required to connect the poles of the upper layer and the poles of the lower layer. The fasteners are generally installed in the form of clamps. This installation method is time-consuming and labor-intensive. Workers also need to install, tighten and lock the fasteners. This installation method is time-consuming and labor-intensive. Utility Model Content

[0003] The utility model aims to solve the problem that it is time-consuming and laborious to connect the existing guardrail uprights of aerial work platforms.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A guardrail upright locking structure includes an upper upright tube and a lower upright tube, and also includes a locking block. A connecting plate is provided on the upper upright tube or the lower upright tube, and a receiving hole is opened on the connecting plate relative to the locking block. The locking block is inserted into the receiving hole. The locking block includes an upper abutment plate, a lower abutment plate and a gradient plate. The upper abutment plate and the lower abutment plate are configured to abut the upper upright tube and the lower upright tube.

[0006] Specifically, the width of the gradient plate gradually decreases from top to bottom, and the width of the accommodating hole is greater than the minimum width of the gradient plate and less than the maximum width of the gradient plate.

[0007] Preferably, the projections of the upper abutment plate and the lower abutment plate at the position of the accommodating hole are both larger than the accommodating hole.

[0008] Preferably, the upper abutment plate and the lower abutment plate are welded to the upper end and the lower end of the gradient plate.

[0009] Preferably, the connecting plate is welded to the upper riser or the lower riser.

[0010] Specifically, the upper abutment plate and the lower abutment plate are provided with connection holes relative to the gradient plate, and the gradient plate is provided with protrusions at positions relative to the connection holes.

[0011] Preferably, V-shaped grooves are provided at positions where the upper abutment plate and the lower abutment plate abut against the upper riser and the lower riser.

[0012] Preferably, a separation gap is provided on a side of the gradient plate close to one end of the lower abutment plate and away from the upper riser or the lower riser.

[0013] By arranging a locking block on the connecting plate, when the upper riser is inserted into the lower riser, the upper abutment plate abuts against the upper riser, and the lower abutment plate abuts against the lower riser. By knocking the upper abutment plate from top to bottom with a heavy object, the entire locking block is knocked downward and moved. However, due to the presence of the gradient plate, the width of the gradient plate relative to the accommodating hole becomes larger and larger until the gradient plate is completely stuck in the accommodating hole. The gradient plate and the accommodating hole have an interference fit, thereby achieving the locking block being stuck on the connecting plate, and then the upper abutment plate and the lower abutment plate are completely stuck on the upper riser and the lower riser, and finally the connection between the upper riser and the lower riser is completed and stuck.

[0014] Because the connecting plate is welded on the upper riser or the lower riser, and the locking block can only be on the connecting plate because of the upper and lower abutment plates, the operator does not need to carry additional fasteners. The connection can be completed by using the matching upper and lower risers. The entire process only requires a tool hammer, and the operation only requires knocking. No other additional operations are required. The use of this locking structure simplifies the installation method and can greatly improve the progress of the project.

[0021] The specific structure and function of the guardrail upright disclosed in this invention are specifically described below.

[0022] Reference Figure 1 As shown, in this embodiment: a guardrail upright locking structure includes an upper vertical pipe 1 and a lower vertical pipe 2, and also includes a locking block 3. A connecting plate 4 is provided on the upper vertical pipe 1 or the lower vertical pipe 2. A receiving hole 41 is opened on the connecting plate 4 relative to the locking block 3. The locking block 3 is inserted into the receiving hole 41. The locking block 3 includes an upper abutment plate 31, a lower abutment plate 33 and a gradient plate 32. The upper abutment plate 31 and the lower abutment plate 33 are configured to abut the upper vertical pipe 1 and the lower vertical pipe 2.

[0023] like Figure 5 As shown, the width of the gradient plate 32 gradually decreases from top to bottom. In order to allow the accommodating hole 41 to clamp the gradient plate 32 , the width of the accommodating hole 41 is greater than the minimum width of the gradient plate 32 and less than the maximum width of the gradient plate 32 .

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, in order to make the connecting plate 4 and the locking block 3 become one and prevent them from falling relative to each other, the projections of the upper support plate 31 and the lower support plate 33 at the position of the accommodating hole 41 are both larger than the accommodating hole 41, and the locking block 3 can slide in the accommodating hole 41 of the connecting plate 4 when not locked. By arranging the locking block 3 on the connecting plate 4, when the upper riser 1 is inserted into the lower riser 2, the upper abutting plate 31 abuts against the upper riser 1, and the lower abutting plate 33 abuts against the lower riser 2. By knocking the upper abutting plate 31 from top to bottom with a heavy object, the entire locking block 3 is knocked downward and moved. However, due to the presence of the gradient plate 32, the width of the gradient plate 32 relative to the accommodating hole 41 becomes larger and larger until the gradient plate 32 is completely stuck in the accommodating hole 41. The gradient plate 32 and the accommodating hole 41 have an interference fit, thereby achieving the locking block 3 being stuck on the connecting plate 4, and then the upper abutting plate 31 and the lower abutting plate 33 are completely stuck on the upper riser 1 and the lower riser 2, and finally the connection between the upper riser 1 and the lower riser 2 is completed and stuck.

[0025] Because the connecting plate 4 is welded to the upper riser 1 or the lower riser 2, and the locking block 3 can only be on the connecting plate 4 due to the upper abutment plate 31 and the lower abutment plate 33, the operator does not need to carry additional fasteners. The connection can be completed by using the matching upper riser 1 and lower riser 2. The entire process only requires a tool hammer to complete, and the operation only requires knocking. No other additional operations are required. The use of this locking structure simplifies the installation method and can greatly improve the progress of the project.

[0026] In order to stabilize the entire locking block 3 , the upper abutment plate 31 and the lower abutment plate 33 are welded to the upper and lower ends of the gradient plate 32 .

[0027] like Figure 1 As shown, the connecting plate 4 is welded to the upper riser 1 or the lower riser 2 .

[0028] In order to facilitate the connection and welding of the gradient plate 32, the upper abutment plate 31 and the lower abutment plate 33, the upper abutment plate 31 and the lower abutment plate 33 are provided with connecting holes 5 relative to the gradient plate 32, and the gradient plate 32 is provided with protrusions 6 at the position relative to the connecting holes 5. The protrusions 6 are inserted into the connecting holes 5, and then the welding operation is performed, which further ensures the position between the gradient plate 32, the upper abutment plate 31 and the lower bottom plate 33, and ensures the consistency of the product.

[0029] like Figure 3 and Figure 4 The upper abutment plate 31 and the lower abutment plate 33 are provided with V-shaped grooves at the positions where they abut against the upper vertical pipe 1 and the lower vertical pipe 2. The V-shaped grooves can make the upper abutment plate 31 and the lower abutment plate 33 fit the upper column and the lower column more closely, and prevent the upper abutment plate 31 and the lower abutment plate 33 from relative lateral displacement with the upper column and the lower column to cause falling off. The V-shaped grooves further enhance the stability of the locking structure.

[0030] like Figure 5 As shown, a separation gap 7 is provided on one side of the gradient plate 32 close to the lower abutment plate 33 and away from the upper riser 1 or the lower riser 2 .

[0031] When locking is not required, the lower support plate 33 is struck from bottom to top with a tool hammer to move the gradient plate 32 upward, thereby causing the gradient plate 32 and the receiving hole 41 to be displaced, so that the gradient plate 32 and the receiving hole 41 are out of the interference state, thereby achieving the release of locking.

[0032] The disengagement gap 7 is provided to facilitate the disengagement of the locking structure from the locking setting. When disengaging upward, the disengagement gap 7 allows the gradient plate 32 to move outward to a greater extent in the accommodating hole 41, further avoiding falling off and getting stuck, and improving the disengagement adaptability of the locking structure.

[0033] The above is only a preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model. In the description of the utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood by specific circumstances.
