Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, for the scaffold with adjustable height disclosed in the present invention, including a sleeve 1, the sleeve 1 includes a pair of first sleeves 11 and a pair of second sleeves 12, and each pair of first sleeves 11 and each pair of second sleeves 12 are connected to each other through a folding member 4. The first sleeve 11 and the second sleeve 12 are connected by the telescopic member 5. A gangboard 7 is laid above the sleeve 1, and the gangboard 7 provides a masonry working surface.

As shown in fig. 2, the sleeve 1 is provided with a height-adjustable lifting mechanism, the lifting mechanism comprises a supporting rod 2 sleeved in the sleeve 1, and the supporting rod 2 can slide up and down inside the sleeve 1, so as to adjust the height of the scaffold. The sleeve 1 is fixedly connected with the support rod 2 through a locking mechanism 3.

As shown in fig. 2, the locking mechanism 3 includes a plurality of pairs of clamping grooves 31 arranged on the support rod 2, wherein a pair of clamping grooves 31 are clamped with clamping blocks 32, one side of the clamping block 32 away from the bottom surface of the clamping groove 31 is fixedly connected with a connecting rod 33, two sliding grooves 34 are arranged in the sleeve 1, the connecting rod 33 is arranged in the sliding groove 34, the clamping block 32 is slidably connected with the sliding grooves 34, and one end of the connecting rod 33 away from the clamping block 32 penetrates through the side wall of the sleeve 1 and is fixedly connected with a fixing block 35. The connecting rod 33 is sleeved with a spring 36, one end of the spring 36 is fixedly connected with the clamping block 32, and the other end of the spring is fixedly connected with the end face of the sliding groove 34. When the spring 36 is in a state of not receiving an external force, the catching block 32 is caught with the catching groove 31.

When the height of the scaffold needs to be adjusted, the fixing block 35 is pulled in the direction far away from the clamping groove 31, the fixing block 35 drives the connecting rod 33 and the clamping block 32 to move in the direction far away from the clamping groove 31 until the clamping block 32 exits from the clamping groove 31, and at the moment, the spring 36 is in a compressed state; move bracing piece 2 to required height about in sleeve pipe 1 afterwards, make joint piece 32 align rather than nearest joint groove 31 simultaneously, loosen fixed block 35, joint piece 32 gets into joint groove 31 and with joint groove 31 joint under the effort of spring 36, supports bracing piece 2 tightly.

As shown in figure 3, the scaffold is foldable for convenient movement and storage. The folding member 4 comprises a rod body 41 rotatably connected to each first sleeve 11 and each second sleeve 12, the rod bodies 41 on the two first sleeves 11 are rotatably connected to each other, and the rod bodies 41 on the two second sleeves 12 are rotatably connected to each other.

When needs are folding with this scaffold, stir the hinged end between the body of rod 41 downwards, stimulate first sleeve 11 and second sleeve 12 simultaneously, make two first sleeve 11 move in opposite directions, two second sleeve 12 also move in opposite directions simultaneously, when pasting tightly respectively between two first sleeve 11 and between two second sleeve 12, this scaffold is folding to be accomplished.

As shown in fig. 3, the scaffold is easily tilted by connecting one folding member 4 between each pair of first sleeves 11 and between each pair of second sleeves 12, and in order to stabilize the connection between two first sleeves 11 and between two second sleeves 12, there are two folding members 4 connected between each pair of first sleeves 11 and between each pair of second sleeves 12.

In order to avoid that the two folding members 4 collide and interfere with each other when folded, the two folding members 4 are located on different sides of the sleeve 1.

As shown in fig. 3, the first casing 11 and the second casing 12 are connected by the telescopic member 5, so that the distance between the first casing 11 and the second casing 12 is adjustable, and the gangway 7 (see fig. 1) with different lengths can be conveniently laid on the casing 1 according to different construction requirements.

The telescopic member 5 comprises a mounting rod 51 fixedly connected with the first sleeve 11, the mounting rod 51 is of a hollow structure, and the mounting rod 51 is located on one side of the first sleeve 11 close to the second sleeve 12. A receiving rod 52 is fixedly connected to one surface of the second sleeve 12 close to the first sleeve 11, and the receiving rod 52 is sleeved with the mounting rod 51. The mounting rod 51 is provided with a first threaded hole 511, the bearing rod 52 is provided with a plurality of second threaded holes 521, and the first threaded hole 511 and one of the second threaded holes 521 are in threaded connection with a bolt 53.

When the length of the laid springboard 7 changes, so that the distance between the first sleeve 11 and the second sleeve 12 needs to be adjusted, the bolt 53 is screwed to separate the bolt 53 from the adapting rod 52 and the mounting rod 51, then the adapting rod 52 is pulled, the adapting rod 52 moves in the mounting rod 51 until the required distance between the first sleeve 11 and the second sleeve 12 is reached, meanwhile, the first threaded hole 511 is aligned with the second threaded hole 521 closest to the first threaded hole, and finally, the bolt 53 is screwed to fixedly connect the adapting rod 52 with the mounting rod 51.

In order to prevent the scaffold from being more stable on the ground, a frustum-shaped stabilizing block 6 is fixedly connected to the bottom surface of the support rod 2. The contact area of the stabilizing block 6 and the ground is larger than the area of the supporting rod 2 which is directly contacted with the ground.

The implementation principle of the embodiment is as follows: when the masonry is built to a certain height and a scaffold needs to be erected, the scaffold is transported to a required place, then the first sleeves 11 and the second sleeves 12 are pulled to unfold the folded scaffold, when the two first sleeves 11 and the two second sleeves 12 are kept horizontal, the scaffold is unfolded completely, and the scaffold is most stable; and finally, paving a springboard 7 on the sleeve 1.

When scaffold height needs to be adjusted, two staff together stimulate two fixed blocks 35 to make joint block 32 withdraw from joint groove 31, move bracing piece 2 to required height in cover pipe 1 up and down afterwards, make joint block 32 align rather than nearest joint groove 31 simultaneously, loosen fixed block 35 at last, make joint block 32 and joint groove 31 joint.

When it is desired to adjust the distance between the first and

second sleeves

11, 12, the bolt 53 is disengaged from the adapter 52 and the mounting rod 51, the adapter 52 is then pulled until the desired distance between the first and

second sleeves

11, 12 is reached, while the first threaded hole 511 is aligned with the second threaded hole 521 closest thereto, and finally the bolt 53 is tightened to fixedly connect the adapter 52 to the mounting rod 51.

After the scaffold is used up, the hinged end between the rod body 41 is stirred downwards, the first sleeve 11 and the second sleeve 12 are pulled simultaneously until the first sleeve 11 and the second sleeve 12 are respectively attached tightly, and the scaffold is folded.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
