Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a telescopic socket horizontal rod. Background Art

[0002] The socket scaffolding is a new type of construction scaffolding system, which is composed of vertical poles, horizontal bars (socket horizontal bars), diagonal bars and nodes, etc. It adopts pin-type connection and has the characteristics of rapid assembly, high strength, material saving, safety and stability. The horizontal bar of the socket scaffolding is mainly used to support and balance the horizontal part of the entire scaffolding structure. The existing socket horizontal bars mainly include fixed type and telescopic type.

[0003] For example, the Chinese utility model patent with the patent publication number CN211341649U and the publication date of August 25, 2020 discloses a telescopic multi-functional cross bar. The structure includes a sleeve, a first lead screw and a first rotating handle. One end of the sleeve is installed with the first lead screw through threaded connection, and the other end is installed with a fastener. The other end of the first lead screw is installed with a fastener or a keel connector. A rotating through hole is provided on the first lead screw, and the first rotating handle passes through the rotating through hole. The length of the first lead screw is adjusted by rotating the first rotating handle.

[0004] The general structural principle of the telescopic multi-functional cross bar in the utility model patent is as follows: A rotating through hole is provided on the first lead screw, and the first rotating handle extends into the rotating through hole. When the length of the first lead screw is long, it is convenient to quickly rotate the first lead screw. When the first rotating handle is set in the horizontal direction, the outer diameter of the middle part of the first rotating handle is smaller than that of the rest of the part, effectively preventing the first rotating handle from falling off from the rotating through hole of the first lead screw when building the scaffolding. A rotating through hole is provided on the sleeve, and the second rotating handle extends into the rotating through hole to adjust the lengths of the first lead screw and the second lead screw.

[0005] However, in the actual use process of the guiding and deviation-correcting device, there are at least the following two deficiencies, in other words, these are the technical problems to be solved by the present utility model.

[0006] 1. The rotating through hole and the rotating handle are detachably arranged. During transportation, the rotating handle is easy to be lost, and during use, the rotating handle needs to be installed, which is not convenient for quick use.

[0007] 2. The sleeve and the lead screw are only engaged by threads, and during adjustment, there is a harmful phenomenon that the lead screw is easily dropped after being over-rotated.

[0008] Therefore, in summary, there is an urgent need for a new type of socket horizontal rod with a fixed handle and preventing the sleeve and the lead screw from being separated under force. Summary of the Utility Model

[0009] The utility model provides a telescopic disc buckle horizontal rod, which can, by means of arranging a rotating fixing rod unit and a tension spring unit on an internal thread sleeve and a threaded rod, achieve the following: 1. During transportation, the rotating fixing rod unit is fixed on the threaded rod by screwing, and there is no need for prior installation or disassembly during use or disassembly, so it is not easy to be lost, and the operation is convenient and the structure is simple; 2. The tension spring units are respectively connected to the internal thread sleeve and the threaded rod, so that the threaded rod is simultaneously subjected to the pulling force of the tension spring unit during telescoping, avoiding the separation of the internal thread sleeve and the threaded rod. The pulling force of the tension spring unit is affected by the distance that the threaded rod is screwed out, which can, to a certain extent, prompt the user of the telescoping limit of the threaded rod, and can play a buffering role when the threaded rod retracts.

[0010] The technical solution adopted by the utility model to solve the above problems is: a telescopic disc buckle horizontal rod, the structure of which includes a fastener, an internal thread sleeve and a threaded rod, and further includes a rotating fixing rod unit arranged on the threaded rod and a tension spring unit arranged in the internal thread sleeve and used for connecting the threaded rod.

[0013] A further preferred technical solution lies in that: the rotating fixing rod unit further includes a rotating opening arranged on the holding rod and used for inserting the radially extending rod.

[0014] A further preferred technical solution lies in that: the rotating fixing rod unit further includes an anti-drop end block arranged on the radially extending rod and used for blocking and limiting the holding rod.

[0015] A further preferred technical solution lies in that: the rotating fixing rod unit further includes an anti-collision limiting ring sleeved on the radially extending rod and, after the screwing length of the threaded rod is adjusted, used for parallelly arranging the threaded rod and the holding rod by elastically clamping the holding rod.

[0016] A further preferred technical solution lies in that: the tension spring unit includes a tension spring body arranged in the internal thread sleeve and connecting the threaded rod.

[0017] A further preferred technical solution lies in that: the tension spring unit further includes a first spring mounting plate arranged on the threaded rod and a second spring mounting plate arranged in the internal thread sleeve.

[0031] The following is only a preferred embodiment of the present utility model, and does not limit the scope of the present utility model.

[0032] As shown Figures 1-6 shown, a telescopic disc buckle horizontal rod, the structure includes a fastener 11, an inner threaded sleeve 12 and a threaded rod 13, and further includes a rotating fixing rod unit 1 provided on the threaded rod 13, and a tension spring unit 2 provided inside the inner threaded sleeve 12 and used for connecting the threaded rod 13.

[0033] In this embodiment, the fastener 11 is used to be fixed on the disc b, so as to connect and support the vertical rod a. The inner threaded sleeve 12 is arranged at the other end of the fastener 11, and the inner threaded sleeve 12 is connected by the threaded rod 13, so that the inner threaded sleeve 12 and the threaded rod 13 can support the vertical rod a.

[0034] In addition, the rotating fixing rod unit 1 is fixedly arranged on the threaded rod 13 and is used to adjust the telescopic distance of the threaded rod 13, so as to be applicable to the distances between different vertical rods a. Moreover, the rotating fixing rod unit 1 is fixedly arranged on the threaded rod 13, which not only facilitates the adjustment of the telescopic distance of the threaded rod 13, but also will not fall off or be lost during transportation or use, and can be used without installation.

[0035] Finally, the function of the tension spring unit 2 is to increase the connection adhesion between the threaded rod 13 and the inner threaded sleeve 12, prevent the threaded rod 13 from being separated from the inner threaded sleeve 12 after being overly screwed out during adjustment, resulting in the harmful phenomenon of falling off. At the same time, the more the threaded rod 13 is screwed out, the greater the pulling force of the tension spring unit 2, which can, to a certain extent, prompt the user of the telescopic limit of the threaded rod 13.

[0036] The rotating fixing rod unit 1 includes a radially extending rod 101 arranged on the threaded rod 13.

[0037] In this embodiment, the function of the radially extending rod 101 is to adjust the telescopic distance of the threaded rod 13.

[0038] The rotating fixing rod unit 1 further includes a holding rod 102 arranged on the radially extending rod 101.

[0039] In this embodiment, the function of the holding rod 102 is to save effort and reduce the extending distance of the radially extending rod 101, so as to better rotate the threaded rod 13.

[0040] The rotating fixing rod unit 1 further includes a rotating opening 103 arranged on the holding rod 102 and used for inserting the radially extending rod 101.

[0041] In this embodiment, the rotation opening 103 is provided on the holding rod 102, so that the holding rod 102 can rotate left and right on the radial extension rod 101, presenting a horizontally overlapping or vertically misaligned state with the threaded rod 13 from a top-down perspective. When the holding rod 102 needs to adjust the threaded rod 13, the holding rod 102 is vertically misaligned with the threaded rod 13, facilitating knob operation; when transporting or after knob operation, to facilitate transportation and prevent the holding rod 102 from interfering with the surrounding environment, the holding rod 102 is rotated to a state where it horizontally overlaps with the threaded rod 13, which is convenient and efficient to use.

[0042] The rotation fixing rod unit 1 further includes a fall-preventing end block 104 provided on the radial extension rod 101 and used to block and limit the holding rod 102.

[0043] In this embodiment, the function of the fall-preventing end block 104 is to prevent the wear between the rotation opening 103 and the radial extension rod 101 after the holding rod 102 is rotated too frequently, resulting in loosening and falling off of the holding rod 102.

[0044] The rotation fixing rod unit 1 further includes an anti-collision limiting ring 105 sleeved on the radial extension rod 101. After the screwing length of the threaded rod 13 is adjusted, the anti-collision limiting ring 105 elastically clamps the holding rod 102 to horizontally arrange the threaded rod 13 and the holding rod 102.

[0045] In this embodiment, the function of the anti-collision limiting ring 105 is to limit and support the position of the holding rod 102 after rotation, facilitating the user to release force after rotation, making it more convenient to use, and at the same time reducing the situation of spontaneous rotation caused by accidental collision with the surrounding.

[0046] The tension spring unit 2 includes a tension spring body 201 provided in the internally threaded sleeve 12 and connecting the threaded rod 13.

[0047] In this embodiment, one end of the tension spring body 201 is provided in the internally threaded sleeve 12 near the fastener 11, and the other end is connected to the port of the threaded rod 13, so as to facilitate limiting and pulling the threaded rod 13 to prevent it from falling off due to force.

[0048] The tension spring unit 2 further includes a first spring mounting plate 202 provided on the threaded rod 13 and a second spring mounting plate 203 provided in the internally threaded sleeve 12.

[0049] In this embodiment, the first spring mounting plate 202 is used to connect the tension spring body 201 and the threaded rod 13. Similarly, the second spring mounting plate 203 is used to connect the internal thread sleeve 12 and the tension spring body 201.

[0050] The second spring mounting plate 203 is arranged on the fastener 11.

[0051] In this embodiment, the second spring mounting plate 203 can be fixedly arranged on the fastener 11 or clamped on the fastener 11, so as to facilitate the replacement of the tension spring unit 2.

[0052] The telescopic disk buckle horizontal rod further includes a threaded hole 3 arranged on the internal thread sleeve 12, and a locking nut 4 arranged on the threaded hole 3 and used for clamping the threaded rod 13.

[0053] In this embodiment, the threaded hole 3 is arranged on the internal thread sleeve 12, and the threaded rod 13 is fixed by the locking nut 4 to prevent the threaded rod 13 from shifting. The locking nut 4 can be arranged at the upper and lower ends of the internal thread sleeve 12.
