[0002] Guardrails generally consist of columns, handrails, and crossbars, which can play a corresponding blocking and protective role. At present, various metal guardrails formed by connecting steel wire ropes between the columns on both sides are widely used because of their easy installation and good impact resistance. However, due to different protection matters, protective guardrails of different heights and sizes are required, that is, columns of different heights are required for coordinated use, but the assembly height of existing columns is mostly fixed and cannot be adjusted. Therefore, in traditional production, it is necessary to produce columns of several different lengths, but this will result in a large number of columns and a significant increase in the overall inventory of columns, so further improvement is needed.

Detailed implementation manner

[0026] The following further describes the present utility model through specific implementation manners.

[0027] As Figures 1 to 10 shown, a column for facilitating the adjustment of the assembly height according to the present utility model includes a top support piece 1, a plurality of middle columns 2, a bottom plate 3, a steel wire rope 4 and a connection and tensioning mechanism 5. The top support piece 1, the plurality of middle columns 2 and the bottom plate 3 are arranged in sequence from top to bottom. A first splicing structure 6 is provided between the top support piece 1 and the adjacent middle column 2. A second splicing structure 7 is provided between two adjacent middle columns 2. A third splicing structure 8 is provided between the bottom plate 3 and the adjacent middle column 2. The steel wire rope 4 is multiple and penetrates through the top support piece 1, the plurality of middle columns 2 and the bottom plate 3. The steel wire rope 4 fixes and connects the top support piece 1, the plurality of middle columns 2 and the bottom plate 3 into a whole through the connection and tensioning mechanism 5.

[0028] Through the arrangement of the steel wire rope 4 and the connection and tensioning mechanism 5, it is convenient to fixedly connect the top support piece 1, the plurality of middle columns 2 and the bottom plate 3 into a whole. At the same time, with the combined use of the first splicing structure 6, the second splicing structure 7 and the third splicing structure 8, it can better ensure the stability of the connection between the top support piece 1 and the adjacent middle column 2, between two adjacent middle columns 2, and between the bottom plate 3 and the adjacent middle column 2. By setting different numbers of the middle columns 2, columns with different assembly heights can be formed. The assembly height of the column can be flexibly adjusted according to different protection matters to better meet different protection requirements. There is no need to produce multiple columns with different lengths. Only a number of middle columns 2 with the same length need to be produced, which can effectively reduce the types of columns and the overall inventory.

[0029] Correspondingly, the connection and tensioning mechanism 5 includes a lower crimping sleeve 51, an upper crimping sleeve 52, and an adjusting screw 53. The top support piece 1 is provided with a plurality of threaded holes 11 penetrating through its upper and lower ends. The outer surface of the adjusting screw 53 is provided with an external thread 531 and is threadedly connected to the threaded hole 11 through the external thread 531. The adjusting screw 53 is provided with an upper through hole 532 penetrating through its upper and lower ends. The outer surface of the top of the adjusting screw 53 is provided with two symmetrical flat sections 533, thereby facilitating the use of a corresponding clamping tool to clamp on the two flat sections 533 to drive the rotation of the adjusting screw 53. The middle column 2 is provided with a plurality of middle through holes 21 penetrating through its upper and lower ends. The bottom plate 3 is provided with a plurality of lower through holes 31 penetrating through its upper and lower ends. The plurality of threaded holes 11, the plurality of middle through holes 21, and the plurality of lower through holes 31 all correspond to the plurality of steel wires 4 one by one. The bottom end of the steel wire 4 is fixedly crimped with the lower crimping sleeve 51. The top end of the steel wire 4 extends upward and sequentially passes through the lower through hole 31 of the bottom plate 3, the middle through holes 21 of the plurality of middle columns 2, and the upper through hole 532 of the adjusting screw 53 and is fixedly crimped with the upper crimping sleeve 52. The bottom surface of the bottom plate 3 is provided with a receiving cavity 32 for receiving the lower crimping sleeve 51. Thus, during assembly, a corresponding clamping tool can be used to clamp on the two flat sections 533 to drive the rotation of the adjusting screw 53, thereby jacking up the upper crimping sleeve 52 upward to tighten the steel wire 4, so as to fixedly connect the top support piece 1, the plurality of middle columns 2, and the bottom plate 3 into a whole. Its assembly operation is fast, simple, and relatively easy and convenient.

[0030] In addition, a washer 54 is further provided between the adjusting screw 53 and the upper crimping sleeve 52. The washer 54 is sleeved on the steel wire 4. Preferably, the washer 54 is a thin metal ring. When the adjusting screw 53 is rotated, the friction between the adjusting screw 53 and the upper crimping sleeve 52 can be effectively reduced.

[0031] The middle column 2 is provided with a cavity 22 penetrating through its upper and lower ends, and chamfered grooves 23 are formed at the openings at both the upper and lower ends of the middle column 2.

[0032] Correspondingly, the first embedding structure 6 includes a first embedding block 61 and the chamfered groove 23. The first embedding block 61 is adapted to the chamfered groove 23. The first embedding block 61 is fixedly provided on the lower end surface of the top support piece 1. The first embedding block 61 is detachably embedded in the chamfered groove 23 of the adjacent lower middle column 2, thereby making the connection between the top support piece 1 and the adjacent middle column 2 more stable.

[0033] Correspondingly, the second splicing structure 7 includes a second splicing block 71 and the splicing groove 23. The second splicing block 71 includes a connecting plate 711, an upper splicing block 712 and a lower splicing block 713 which are respectively fixed at the upper and lower ends of the connecting plate 711. A first round hole 7111 through which the steel wire rope 4 can pass is provided on the connecting plate 711. The first round holes 7111 are multiple and correspond to the multiple steel wire ropes 4 one by one. Both the upper splicing block 712 and the lower splicing block 713 are adapted to the splicing groove 23. The upper splicing block 712 is detachably embedded in the splicing groove 23 of the adjacent middle column 2 above, and the lower splicing block 713 is detachably embedded in the splicing groove 23 of the adjacent middle column 2 below. Thus, the connection between two adjacent middle columns 2 can be made more stable.

[0034] In addition, at least one spacer 9 is provided between two adjacent middle columns 2. An insertion hole 91 adapted to the upper splicing block 712 and the lower splicing block 713 is provided in the spacer 9. A second round hole 92 through which the steel wire rope 4 can pass is also provided on the spacer 9. The second round holes 92 are multiple and correspond to the multiple steel wire ropes 4 one by one. Correspondingly, the spacer 9 can be inserted on the upper splicing block 712 or the lower splicing block 713 through the insertion hole 91 to ensure the stability during the assembly of the spacer 9. At the same time, by setting different numbers of spacers 9, it is convenient to further finely adjust the overall assembly height of the column.

[0035] Correspondingly, the third splicing structure 8 includes a third splicing block 81 and the splicing groove 23. The third splicing block 81 is adapted to the splicing groove 23. The third splicing block 81 is fixed on the upper end surface of the bottom plate 3. The third splicing block 81 is detachably embedded in the splicing groove 23 of the adjacent middle column 2 above. Thus, the connection between the bottom plate 3 and the adjacent middle column 2 can be made more stable.

[0036] In addition, at least one mounting hole 24 penetrating through two opposite outer surfaces of the middle column 2 is provided, which facilitates the installation of the steel wire rope 4 or the cross bar.

[0037] Preferably, the number of the steel wire ropes 4 is four. The four steel wire ropes 4 are respectively arranged at the four corners of the column, thus better ensuring the stability of the overall assembly of the column. That is, the number of the upper crimping sleeve 52, the lower crimping sleeve 51, the adjusting screw 53, the washer 54, the threaded hole 11, the middle through hole 21, the lower through hole 31, the first round hole 7111 and the second round hole 92 is also four.

[0038] The using method of a column facilitating the adjustment of the assembly height according to the present utility model is as follows:

[0039] Screw four adjusting screws 53 into the four threaded holes 11 of the top support plate 1 respectively;

[0040] Cut four steel wire ropes 4 with appropriate lengths according to the actual height requirements;

[0041] Use corresponding crimping tools to fixedly crimp four lower crimping sleeves 51 to one end of the four steel wire ropes 4 respectively;

[0042] Pass the other ends of the four steel wire ropes 4 simultaneously through the four lower through holes 31 of the bottom plate 3, the four intermediate through holes 21 of the plurality of intermediate columns 2, and the upper through holes 532 of the four adjusting screws 53 on the top support plate 1 in sequence;

[0043] Pre-tighten the steel wire ropes 4, determine the crimping positions of the upper crimping sleeves 52, and then use corresponding crimping tools to fixedly crimp the four upper crimping sleeves 52 to the other ends of the four steel wire ropes 4 respectively;

[0044] Use corresponding clamping tools to clamp on the two flat cutting surfaces 533 of the adjusting screw 53 to drive the adjusting screw 53 to rotate, thereby jacking up the upper crimping sleeve 52 upward to tighten the steel wire rope 4, so as to fixedly connect the top support plate 1, the plurality of intermediate columns 2 and the bottom plate 3 into a whole and form a column with a corresponding assembled height;

[0045] Cut off the excess length at the other end of the steel wire rope 4.

[0046] It should be understood that in the development process of any actual implementation manner, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine task of design, manufacturing and production.

[0047] The above are only several specific implementation manners of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
