Description

Technical Field

[0001] This invention relates to the field of building scaffolding technology, and more specifically to an adjustable diagonal brace for a disc-lock scaffolding system. Background Technology

[0002] Construction scaffolding is an indispensable facility in construction operations. With the rapid development of the construction industry, the requirements for scaffolding selection and safe use are becoming increasingly stringent. Socket-type disc-lock scaffolding, with its advantages of multiple functions, high efficiency, large load-bearing capacity, safety, reliability, and long service life, has been rapidly promoted and its market share has significantly increased.

[0003] However, compared to steel pipe coupler scaffolding, socket-type disc-lock scaffolding has a variety of product models and sizes for fixing and matching, resulting in an excessive number of accessories and poor product versatility. This, to some extent, restricts the promotion and use of socket-type disc-lock scaffolding. Furthermore, based on actual market conditions and field experience, the diverse specifications and models of existing disc-lock system diagonal braces have led to difficulties in product matching and inconvenience in use, becoming a significant obstacle to its widespread adoption.

[0004] Among them, the diagonal brace is particularly noticeable; see appendix. Figure 1 In existing socket-type scaffolding, the diagonal brace 10 is generally a single piece with connectors at both ends. Different lengths of diagonal braces are used as needed. Since the length of the diagonal brace cannot be adjusted, multiple diagonal braces of different sizes and specifications need to be manufactured, resulting in a cumbersome diagonal brace system that is not convenient for practical application.

[0005] Therefore, how to provide an adjustable diagonal brace for a disc buckle frame system is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] Therefore, the purpose of this invention is to propose an adjustable diagonal brace for a disc-lock scaffolding system, thereby solving the problem of poor versatility of diagonal braces in existing socket-type disc-lock scaffolding.

[0007] The present invention provides an adjustable diagonal bar for a disc buckle frame system, including a first diagonal bar and a second diagonal bar, wherein the first diagonal bar and the second diagonal bar can be connected to increase or decrease their connection length through a connector.

[0008] Furthermore, both the first and second inclined rods are hollow structures, and the diameter of the first inclined rod is larger than the diameter of the second inclined rod; the second inclined rod is inserted into the first inclined rod and is threadedly connected to the first inclined rod, wherein the connecting member is a threaded structure.

[0009] Furthermore, the inner wall of the first inclined rod has multiple threaded sleeves, and the end of the second inclined rod has an end thread that mates with the threaded sleeves.

[0010] Furthermore, each of the threaded sleeves is provided with multiple arc-shaped thread structures at equal intervals in the radial direction of the first inclined rod, and the number of arc-shaped thread structures of the end thread in the radial direction of the second inclined rod matches the number of arc-shaped thread structures of the threaded sleeve.

[0011] Furthermore, a parallelogram structure connects the first diagonal bar and the second diagonal bar. The parallelogram structure can increase or decrease the connection length between the first diagonal bar and the second diagonal bar, wherein the connector is a parallelogram structure.

[0012] Furthermore, one end of the parallelogram structure is hinged to the first diagonal rod to form hinge point one, and the end opposite to it is hinged to the second diagonal rod to form hinge point two. Hinge points three and four are floating hinge points, and a locking mechanism is provided at the floating hinge points.

[0013] Furthermore, the locking mechanism is a locking device one disposed on the hinge axis of hinge point three and / or hinge point four, the locking device one comprising:

[0014] A hinge shaft 1 passes through the end connection holes 1 of the two connecting pieces of the parallelogram structure, and its end is provided with a blocking part larger than the end connection hole 1, and a cavity 1 with one end open is formed inside the cavity 1, and the cavity 1 has a horizontally placed L-shaped groove.

[0015] Spring one, which is installed inside the cavity one;

[0016] A locking rod, one end of which extends into the cavity, and the other end of which is provided with a protrusion that engages with the L-shaped groove for locking.

[0017] The locking lever has a handle attached to the other end.

[0018] Furthermore, the locking mechanism is a second locking device disposed on the hinge axis of hinge point three and / or hinge point four, and the second locking device includes:

[0019] The second hinge shaft passes through the end connection holes of the two connecting pieces of the parallelogram structure, and its end is provided with a blocking part larger than the end connection hole 2. A through channel 1 is formed inside the channel 1, and a channel 2 is arranged perpendicular to its axis in the radial direction of the channel 1.

[0020] The lock cylinder with a handle is movable within the first channel. In the unlocked state, both ends of the lock cylinder with the handle extend out of the first channel. The end away from the handle has a locking block with the same diameter as the first channel. The locking block has an inwardly recessed locking ring groove in the middle, and the locking ring groove can correspond to the second channel after it moves. A second spring is sleeved on the end of the locking block facing the handle.

[0021] A locking block is vertically movable within the second channel. The locking block can be locked in conjunction with the locking ring groove. The top of the locking block has a top rod, and a spring three is sleeved on the top rod. The second channel corresponding to the top of the spring three forms a spring limiting seat.

[0022] A protective cap is threadedly connected to the top of the second channel to cover the top rod.

[0023] Furthermore, the locking mechanism is a locking plate disposed on the hinge shafts of hinge point three and hinge point four, the locking plate having multiple continuous arc-shaped grooves at both ends, and the locking plate being the connecting member.

[0024] Furthermore, the first and second inclined rods are connected to a stabilizing screw at the ends near the parallelogram structure.

[0025] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an adjustable diagonal bar for a disc buckle frame system, which specifically includes the following beneficial effects:

[0026] 1. This invention divides the overall diagonal brace into a first diagonal brace and a second diagonal brace, and connects the first diagonal brace and the second diagonal brace with a connector. The overall length of the diagonal brace can be increased or decreased by the connector to meet the needs of different diagonal brace lengths, thereby improving the versatility of the diagonal brace. It eliminates the need to manufacture multiple diagonal braces of different sizes and specifications, thus improving the ease of use of the diagonal brace.

[0027] 2. The present invention connects the first and second inclined rods by using a threaded structure. Since each threaded sleeve and the end thread are radially segmented threaded structures, the first and second inclined rods can be moved to a suitable length during use. Then, the corresponding threaded sleeve and the end thread are tightened and positioned by rotation, which can meet the use length of the inclined rods for different needs. The position of the threaded sleeve is determined by classification calculation.

[0028] 3. The present invention uses a parallelogram structure to connect the first and second diagonal bars. The tensile length of the parallelogram structure between the first and second diagonal bars can be changed according to the usage, and then locked, so as to meet the usage length of the diagonal bars for different needs.

[0029] 4. After adopting a parallelogram structure for connection, a stabilizing screw is set to further ensure the connection stability of the first and second diagonal rods. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0048] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0049] See appendix Figure 1Because the existing socket-type scaffolding generally uses a single diagonal brace 10 with connecting structures at both ends, different lengths of diagonal braces are used as needed. Since the length of the diagonal brace cannot be adjusted, multiple diagonal braces of different sizes and specifications need to be manufactured, resulting in a cumbersome diagonal brace system that is not convenient for practical application.

[0050] In view of this, this invention discloses an adjustable diagonal brace for a disc buckle frame system, including a first diagonal brace 21 and a second diagonal brace 22. The first diagonal brace 21 and the second diagonal brace 22 can be connected in length by a connector. This solution divides the overall diagonal brace into a first diagonal brace and a second diagonal brace, connects them by a connector, and adjusts the overall length of the diagonal brace by the connector to meet different usage requirements. This improves the versatility of the diagonal brace, eliminates the need to manufacture multiple diagonal braces of different sizes, and enhances its ease of use.

[0051] In a specific embodiment of the present invention, see Appendix Figure 2-4 Both the first inclined rod 21 and the second inclined rod 22 are hollow structures, and the diameter of the first inclined rod 21 is larger than the diameter of the second inclined rod 22; the second inclined rod 22 is inserted into the first inclined rod 21 and is threadedly connected to the first inclined rod 21, wherein the connecting part is a threaded structure 23.

[0052] Specifically, the inner wall of the first inclined rod 21 has multiple threaded sleeves, and the end of the second inclined rod 22 has an end thread that mates with the threaded sleeves.

[0053] More specifically, each of the threaded sleeves is provided with multiple arc-shaped thread structures at equal intervals in the radial direction of the first inclined rod 21, and the number of arc-shaped thread structures of the end thread in the radial direction of the second inclined rod 22 matches the number of arc-shaped thread structures of the threaded sleeve.

[0054] In this embodiment, the first and second inclined rods are connected by a threaded structure. Since each threaded sleeve and end thread is a radially segmented threaded structure, the first and second inclined rods can be moved to a suitable length during use. Then, the corresponding threaded sleeve and end thread are tightened and positioned by rotation, which can meet the usage length of the inclined rods for different needs.

[0055] This embodiment mainly calculates the length of the diagonal bar under different working conditions, and determines the location of the threaded sleeve through classification and design, so as to meet the diverse usage requirements of existing diagonal bars under different working conditions in terms of specifications and models.

[0056] Specifically, the freely extendable length of the diagonal brace is 500-600mm. Through calculation and analysis, the location of the threaded sleeve was determined, which meets the usage requirements of various spacings in the disc buckle support system.

[0057] The second oblique rod diameter can be Ф48, and the first oblique rod diameter can be Ф52. Through length matching calculations, intermittent threads with a width of 15-20mm can be installed in different working conditions (see details). Figure 1-3 The length of the diagonal brace can be changed or fixed by stretching and rotating it. The thread pitch is designed according to different installation conditions.

[0058] The present invention also provides an embodiment, which can be found in the appendix. Figure 5-14 A parallelogram structure 24 connects the first diagonal bar 21 and the second diagonal bar 22. The parallelogram structure 24 can increase or decrease the connection length between the first diagonal bar 21 and the second diagonal bar 22, wherein the connector is a parallelogram structure 24.

[0059] In this embodiment, a parallelogram structure is used to connect the first and second diagonal bars. The tension length of the parallelogram structure between the first and second diagonal bars can be changed according to the usage, and then locked, thus meeting the usage length of the diagonal bars for different needs.

[0060] Advantageously, one end of the parallelogram structure 24 is hinged to the first diagonal rod 21 to form hinge point one, and the opposite end is hinged to the second diagonal rod 22 to form hinge point two. Hinge points three and four are floating hinge points, and a locking mechanism is provided at the floating hinge points. By locking hinge points three and four of the parallelogram structure, the fixation of the parallelogram structure after stretching is ensured.

[0061] The locking mechanism is a locking device 25 installed on the hinge shaft of hinge point three and / or hinge point four.

[0062] See appendix Figure 8 In a specific embodiment, the locking mechanism comprises two locking devices 25 disposed on the hinge shafts at hinge points three and four, each of the locking devices 25 including:

[0063] The hinge shaft 251 passes through the end connection holes of the two connecting pieces of the parallelogram structure 24, and its end is provided with a blocking part larger than the end connection hole (all blocking parts are not shown in the figure). It forms an open cavity 1 inside, and the cavity 1 has a horizontally placed L-shaped groove 2511.

[0064] Spring 252 is installed inside the cavity.

[0065] Locking rod 253, one end of which extends into the cavity, and the other end of which is provided with a protrusion 2531 that engages with the L-shaped groove 2511 for locking.

[0066] The locking lever 254 is connected to the other end of the locking rod 253.

[0067] The protrusion 2531 is located in the L-shaped groove 2511. The L-shaped groove 2511 includes a horizontal groove and a vertical groove. The horizontal groove is a moving groove, and the vertical groove is a locking groove. When the protrusion 2531 is located in the locking groove, it is in the locked state. Rotate the locking handle 254 to rotate the protrusion 2531 to the moving groove, and then move the locking rod 253 outward to release the locked state. The operation is convenient.

[0068] See appendix Figure 13 In one specific embodiment, the locking mechanism comprises two locking devices 26 disposed on the hinge shafts of hinge point three and hinge point four, each of the locking devices 26 comprising:

[0069] The second hinge shaft 261 passes through the end connection holes 2 of the two connecting pieces of the parallelogram structure 24, and its end is provided with a blocking part larger than the end connection hole 2. A through channel 1 is formed inside, and a channel 2 is arranged perpendicular to its axis in the radial direction of the channel 1.

[0070] The lock cylinder 262 with a handle is movable within the first channel. In the unlocked state, both ends of the lock cylinder 262 with the handle extend out of the first channel. The end away from the handle has a locking block with the same diameter as the first channel. The locking block has an inwardly recessed locking ring groove 2621 in the middle, and the locking ring groove 2621 can correspond to the second channel after it moves. A second spring is sleeved on the end of the locking block facing the handle.

[0071] Locking block 263, vertically movable within the second channel, locking block 263 can cooperate with the locking ring groove 2621 for locking, the top of locking block 263 has a top rod 264, a spring three is sleeved on the top rod 264, and the second channel corresponding to the top of the spring three forms a spring limiting seat;

[0072] A protective cap 265 is threadedly connected to the top of the second channel, which is used to cover the top rod 264.

[0073] In the initial state, the locking block 263 is far from the locking ring groove 2621, the third spring is in a compressed state, and the second spring is in a stretched state, which is the unlocked state; when the lock cylinder 262 with the handle is pulled outward, the locking block 263 enters the locking ring groove 2621, the third spring is in a stretched state, and the second spring is in a compressed state, which is the locked state.

[0074] In another embodiment, see Appendix Figure 14The locking mechanism is a locking plate 27 disposed on the hinge shafts of hinge point three and hinge point four. The locking plate 27 has multiple continuous arc-shaped grooves at both ends and is the connecting member.

[0075] In use, pressing the hinge shafts at hinge points three and four will extend the first and second diagonal rods, while pulling them outwards will shorten them, thus meeting different length requirements. The spacing of the arc-shaped grooves on the locking plate is determined based on the desired length of the diagonal rods under different conditions. Specifically, the extension or shortening length of the first and second diagonal rods is calculated by moving each arc-shaped groove. In other words, the arc-shaped grooves are designed to accommodate different diagonal rod lengths under typical usage conditions.

[0076] In the above embodiments, after using a parallelogram structure for connection, to further ensure the connection stability of the first and second diagonal rods, a stabilizing screw 28 is connected to one end of the first diagonal rod 21 and the second diagonal rod 22 near the parallelogram structure 24. The stabilizing screw 28 is connected to the lead screw nut inside the first and second diagonal rods. The length of the connecting piece of the parallelogram structure also needs to be determined and selected according to the actual application, based on the maximum and minimum connection lengths of the entire diagonal rod.
