Description

Technical Field

[0001] The utility model relates to building construction, in particular to a quick and easy adjustment device for a socket-type disc-lock type scaffolding top support. Background Art

[0002] In order to improve the safety of the scaffolding when in use, it is necessary to make the forces on each upright of the scaffolding basically consistent. For this purpose, a scaffolding top support is designed to provide support.

[0003] At present, there are scaffolding supports that can be extended and retracted by means of threaded connections. However, the current adjustment force is not well controlled, and it is easy for some scaffolding supports to extend further and some scaffolding supports to extend less, resulting in unbalanced support. Further improvements are needed for this purpose. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a quick and easy adjustment device for socket-type disc-type scaffolding top supports, which can conveniently adjust the extension degree of each top support of the scaffolding, making the supporting effect more stable and the support of each top support more balanced.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick and easy adjustment device for a socket-type disc-type scaffolding jacking support, comprising a connecting piece for matching the scaffolding connection, a sleeve arranged on the connecting piece, and a jacking support, wherein the jacking support has a screw rod, and the screw rod is inserted into the sleeve;

[0006] The jacking support is provided with a nut, the nut is threadedly connected with the screw rod of the jacking support, and the nut and the sleeve form a circumferential fixed fit;

[0007] The connecting piece is provided with a scale.

[0008] As a further improvement of the present invention, at least one positioning piece is provided on the sleeve, and a groove for the positioning piece to penetrate is provided on the nut at a position corresponding to the positioning piece; the nut is circumferentially fixed to the sleeve through the cooperation between the groove and the positioning piece.

[0009] As a further improvement of the utility model, the connecting member includes a main body for cooperating with the scaffolding for fixed connection, and a plurality of connecting rods connected to the main body; the sleeve is coaxially arranged with the main body and connected to each other through the connecting rods.

[0010] As a further improvement of the utility model, the connecting rod is connected to the sleeve and the main body by welding.

[0011] As a further improvement of the present utility model, the positioning member is a steel bar.

[0012] As a further improvement of the present invention, the connecting rod is a steel bar.

[0013] The beneficial effect of the utility model is that the screw is inserted into the sleeve and does not need to have a threaded connection with the sleeve. It only needs to serve as a guide and support, so it is easy to install and produce. The circumferential fixation of the nut and the sleeve is equivalent to no circumferential rotation between the two. At this time, the screw of the top support can be extended and retracted in conjunction with the nut. The scale on the connecting piece can be used to cooperate with the bottom of the screw for detection, determine the current screw extension distance, and then measure the current extension size of the top support, which is convenient for controlling each top support to extend to the same length, making the support more stable.

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] Reference Figure 1-3 As shown,

[0020] A quick and easy adjustment device for a socket-type disc-type scaffolding top support 3, comprising a connecting piece 1 for matching the scaffolding connection, a sleeve 2 arranged on the connecting piece 1, and a top support 3, wherein the top support 3 has a screw 4, and the screw 4 is inserted into the sleeve 2;

[0021] A nut 5 is provided on the top support 3, and the nut 5 is threadedly connected to the screw rod 4 of the top support 3, and the nut 5 and the sleeve 2 form a circumferential fixed fit;

[0022] A scale 6 is provided on the connecting member 1 .

[0023] In this solution, the screw 4 is inserted into the sleeve 2 and does not need to have a threaded connection with the sleeve 2. It only needs to serve as a guide. The cooperation between the connector 1 and the sleeve 2 is mainly to provide support. By supporting the nut 5, the support 3 can be achieved.

[0024] The circumferential fixation of the nut 5 and the sleeve 2 is equivalent to that there is no circumferential rotation between the two, and at this time, the screw rod 4 of the top support 3 can be extended and retracted in cooperation with the nut 5. The scale 6 on the connector 1 can be used to cooperate with the bottom of the screw rod 4 for detection, to determine the current extension distance of the screw rod 4, and then to measure the current extension size of the top support 3, so as to facilitate the control of each top support 3 to extend to the same length, so that the support effect is more stable.

[0025] Moreover, the structure of this solution is simpler and the processing is convenient.

[0026] In a specific configuration, at least one positioning member 21 is provided on the sleeve 2, and a groove 51 for the positioning member 21 to penetrate is provided on the nut 5 at a position corresponding to the positioning member 21; the nut 5 is circumferentially fixed to the sleeve 2 through the groove 51 and the positioning member 21.

[0027] The cooperation of the positioning member 21 and the groove 51 can make the cooperation between the sleeve 2 and the nut 5 more stable. As shown in the figure, abutment parts are arranged on both sides of the nut 5, and baffles are arranged on both sides of the abutment parts. At this time, the baffles and the abutment parts constitute the groove 51. The positioning member 21 is inserted into the groove 51 to form circumferential positioning, so that the nut 5 will not rotate circumferentially, and the positioning member 21 can also support the nut 5. It is also easy to install. You only need to install the nut 5 on the screw 4 of the jacking 3, and you can install it by just rotating the nut 5, and then insert the screw 4 into the sleeve 2.

[0028] In a further configuration, the connector 1 includes a main body 11 for cooperating with the scaffold for fixed connection, and a plurality of connecting rods 12 connected to the main body 11 ; the sleeve 2 is coaxially arranged with the main body 11 , and connected to each other via the connecting rods 12 .

[0029] The main body 11 is a part used to cooperate with the scaffolding for insertion or fixed connection by bolts, and the connecting rod 12 is a part used to form a certain distance between the sleeve 2 and the main body 11. The connecting rod 12 can be made of steel bars, and the number can be at least 3, which are distributed circumferentially on the main body 11 and welded to the sleeve 2. At this time, the distance between the sleeve 2 and the main body 11 can allow the screw 4 of the jacking support 3 to penetrate, providing space for the screw 4 to retract.

[0030] The scale 6 can be located on the connecting rod 12, and a thin film tape measure can be used. A plurality of connecting rods 12 can be surrounded by a gap, and the position of the internal screw rod 4 can be seen, and then the scale 6 is matched to measure the telescopic length.

[0031] The connecting rod 12 and the sleeve 2 can be welded, and similarly, the connecting rod 12 and the main body 11 can also be welded. The welding strength is high and the processing is convenient.

[0032] The positioning member 21 and the connecting rod 12 can both be made of steel bars, which have simple raw materials and are easy to weld.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
