Description

Technical Field

[0001] The present invention relates to road traffic signs, and particularly to an installation structure of road traffic signs. Background Art

[0002] Road traffic signs are used to guide and reference road traffic. Common installation structures of road traffic signs include: seamless steel pipes with ground flanges, two groups of hoop fasteners, and sign boards. The seamless steel pipes are fixedly connected to the ground, and the hoop fasteners fixedly connect the sign boards to the seamless steel pipes. On this basis, there are also derived different forms such as the double-column type in which two seamless steel pipes fix one sign board, and the cantilever type in which a horizontal seamless steel pipe extends from the seamless steel pipe for the sign board to be connected. For the fixed connection between the hoop fasteners, seamless steel pipes, and sign boards, generally: two chutes are fixedly connected to the back of the sign board. The chutes are convex, with the notch at the back; the lining and the hoop body of the hoop fastener are connected by two groups of bolts and nuts; the bolts enter the chutes from the notch, and the nuts are in the wider part of the chutes and are restricted from rotating. Tighten the bolts, and at the same time complete the relative fixation between the hoop fastener and the seamless steel pipe and the relative fixation between the hoop fastener and the sign board.

[0003] The up-and-down adjustment of the sign board corresponds to the relative movement of the hoop fastener and the seamless steel pipe, and the left-and-right adjustment of the sign board corresponds to the relative movement of the hoop fastener and the chute. Although such an installation structure is simple in structure, there are also the following problems: Whether it is necessary to adjust the sign board or replace the sign board, the bolts need to be loosened. Once the bolts are loosened, the relative fixation between the hoop fastener and the seamless steel pipe and the relative fixation between the hoop fastener and the sign board will be released, which is equivalent to reinstalling the sign board, resulting in very cumbersome and inconvenient subsequent corresponding operations. Summary of the Invention

[0004] The present application provides an installation structure of road traffic signs, which can solve the problems raised in the background art.

[0005] In the present application, an installation structure of road traffic signs is provided, including: Seamless steel pipes; Sign boards, with two left-and-right facing chutes fixedly connected to the back; Two groups of connection modules, respectively installed in the two chutes; Any one group of connection modules includes: Base; Two abutting blocks, both sliding back and forth on the base; both have limit holes; Two sliders, both sliding left and right on the base; both have left-and-right facing limit grooves; Adjusting part, arranged on the base, used to drive the two sliders to move, so that the two abutting blocks can switch between tightly abutting the inner wall of the rear of the chute and loosening the inner wall of the rear of the chute; Two groups of hoop fasteners, both installed on the seamless steel pipes; Any one group of hoop fasteners includes: Substrate; Two bolts, respectively fixedly connected to the left and right sides of the substrate; both are threaded segments at the back of the substrate; both are connecting segments and nuts at the front of the substrate, the connecting segments pass through the limiting holes, and the nuts are in the limiting grooves, and the limiting holes and limiting grooves are used for: restricting all degrees of freedom of movement of the bolts relative to the base; A hoop body, sleeved on the threaded segments of the two bolts; Two adjusting nuts, respectively connected to the threaded segments of the two bolts.

[0006] In some embodiments, the slider has a blocking portion on one side of the limiting groove; the blocking portion is used for: when moving in a direction away from the abutting block, restricting the nut from leaving the limiting groove.

[0007] In some embodiments, the adjusting portion is a bidirectional lead screw.

[0008] In some embodiments, both the left and right sides of the substrate have limiting outer walls; both the left and right sides of the hoop body have limiting inner walls; when the hoop and the seamless steel pipe are relatively fixed, the limiting inner wall fits against the limiting outer wall on the same side.

[0009] In some embodiments, the base fits against the front inner wall of the sliding groove, and the substrate fits against the rear outer wall of the sliding groove.

[0010] In some embodiments, it further includes: a solar panel, a warning light.

[0011] In summary, in the present application, a road traffic sign installation structure includes: a seamless steel pipe, a sign board surface, two groups of connection modules, and two groups of hoops. A connection module is added between the sliding groove and the hoop. When it is necessary to adjust the position of the sign board surface up and down, loosen the two adjusting nuts, the connection module and the sliding groove remain relatively fixed, and the sign board surface, the two connection modules, and the two hoops move up and down together to adjust the position. When it is necessary to adjust the position of the sign board surface left and right or replace the sign board surface, the driving portion moves the slider in a direction away from the abutting block, and the abutting block switches to loosen the rear inner wall of the sliding groove, so that the connection module and the sliding groove move relatively, the hoop and the seamless steel pipe remain relatively fixed, the sign board surface moves left and right to adjust the position, and the sign board surface can also be removed from the connection module for replacement. The beneficial effects are: when the sign board surface is installed on the seamless steel pipe, it is more convenient to adjust the position; it is also more convenient to replace the sign board surface.

[0016] Please refer to Figure 1 、 Figure 4 and Figure 5 , a road traffic sign installation structure, comprising: a seamless steel pipe 1, a sign panel 2, two sets of connection modules 3, and two sets of clamps 4.

[0017] The seamless steel pipe 1 is used for installing the sign panel 2. For single-column and double-column types, the seamless steel pipe 1 is vertical, and a floor flange 1a is fixedly connected to the bottom end, that is, the seamless steel pipe 1 is fixedly connected to the road surface through the floor flange 1a. For the cantilever type, the seamless steel pipe 1 is horizontal. The single-column type is taken as an example in the accompanying drawings.

[0018] Two sliding grooves 2a are fixedly connected to the back of the sign panel 2. The two sliding grooves 2a face left and right. Correspondingly, the two sliding grooves 2a are arranged one above the other. The cross-section of the sliding groove 2a is a convex shape after rotating 90 degrees, and the notch 2a1 is at the back.

[0019] Please refer to Figure 2 、 Figure 3 and Figure 7 , the two sets of connection modules 3 are respectively installed in the two sliding grooves 2a. Any one set of connection modules 3 includes: a base 31, two abutting blocks 32, two sliders 33, and an adjusting part 34.

[0020] The two abutting blocks 32 are both slidably connected to the base 31 in the front and back directions. More specifically, the abutting block 32 has a stepped hole 32a, and a screw passes through the stepped hole 32a and is threadedly connected to the base 31.

[0021] The two abutting blocks 32 also both have limiting holes 32b. More specifically, the abutting block 32 is in an inverted L shape, the above-mentioned stepped hole 32a is in the vertical part, and the limiting hole 32b is in the horizontal part.

[0022] Both sliding blocks 33 are slidably connected to the base 31 in the left - right direction. Both sliding blocks 33 also have limiting grooves 33b facing left and right.

[0023] The adjusting part 34 is arranged on the base 31. The adjusting part 34 is used to drive the two sliding blocks 33 to move, so that the two abutting blocks 32 can switch between the inner wall 2a3 of the tightening chute 2a and the inner wall 2a3 of the releasing chute 2a. That is to say: the contact surface 33a between the sliding block 33 and the abutting block 32 is inclined. After the contact surface 33a between the sliding block 33 and the abutting block 32 fits, when the sliding block 33 continues to move in the direction closer to the abutting block 32, the sliding block 33 can drive the abutting block 32 to move backward through its own movement; the base 31 fits against the front inner wall 2a2 of the chute 2a, and when the abutting block 32 moves backward, it can abut against the inner wall 2a3 of the rear chute 2a, so that the connecting module 3 and the chute 2a are relatively fixed. Correspondingly, when the sliding block 33 moves in the direction away from the abutting block 32, the abutting block 32 switches to releasing the inner wall 2a3 of the rear chute 2a, so that the connecting module 3 and the chute 2a move relatively.

[0024] In some embodiments, the adjusting part 34 is a bidirectional lead screw. More specifically: the base 31 is concave, the sliding connection positions of the two sliding blocks 33 on the base 31 are horizontal parts, and the rotational connection positions of the bidirectional lead screw on the base 31 are two vertical parts; the two lead screw nuts 34a matching the bidirectional lead screw are respectively fixedly connected to the two sliding blocks 33; the two abutting blocks 32 are arranged in mirror symmetry, and the abutting block 32 also has a through - hole 32c for the bidirectional lead screw to pass through.

[0025] The end of the bidirectional lead screw can have a slot. By inserting a screwdriver into the chute 2a to drive the bidirectional lead screw to rotate, the structure is simple and the operation is convenient.

[0026] Please refer to Figure 2 and Figure 6 Two sets of hoop fasteners 4 are both installed on the seamless steel pipe 1. Any set of hoop fasteners 4 includes: a substrate 41, two bolts 42, a hoop body 43, and two adjusting nuts 44.

[0027] The middle position of the substrate 41 is an arc - shaped notch 41a that fits onto the outer wall of the seamless steel pipe 1, and the left and right positions are both first connecting pieces 41b.

[0028] Two bolts 42 are respectively fixedly connected to the left and right sides of the substrate 41, that is, respectively fixedly connected to two first connecting pieces 41b. Both of the two bolts 42 have threaded segments 421 behind the substrate 41, and both of the two bolts 42 have connecting segments 422 and nuts 423 in front of the substrate 41. The fixed connection method between the bolt 42 and the substrate 41 can be: the diameter of the connecting segment 422 is larger than the major diameter of the threaded segment 421. After the threaded segment 421 passes through the first connecting piece 41b, a connecting nut 4142 is connected. By tightening the connecting nut 4142, the connecting segment 422 and the connecting nut 4142 respectively abut against the front and rear of the first connecting piece 41b.

[0029] The hoop body 43 is in a U shape, and second connecting pieces 43a are bent outward at both ends. The hoop body 43 is sleeved on the threaded segments 421 of the two bolts 42, that is, the two threaded segments 421 also respectively pass through the two second connecting pieces 43a.

[0030] Two adjusting nuts 44 are respectively connected to the threaded segments 421 of the two bolts 42. That is to say: after the hoop body 43 is sleeved on the threaded segments 421 of the two bolts 42, the seamless steel pipe 1 is located between the hoop body 43 and the bushing. By tightening the two adjusting nuts 44, the arc-shaped inner wall 43b of the hoop body 43 and the arc-shaped notch 41a of the substrate 41 respectively abut against the front and rear of the seamless steel pipe 1, so that the hoop 4 and the seamless steel pipe 1 are relatively fixed. Correspondingly, by loosening the two adjusting nuts 44, the hoop 4 and the seamless steel pipe 1 can move relatively.

[0031] In some embodiments, both the left and right sides of the substrate 41 have limiting outer walls 41c. Both the left and right sides of the hoop body 43 have limiting inner walls 43c. In the state where the hoop 4 and the seamless steel pipe 1 are relatively fixed, the limiting inner wall 43c abuts against the limiting outer wall 41c on the same side.

[0032] The hoop body 43 and the substrate 41 can be more stable.

[0033] Please refer to Figure 6 and Figure 7 , the hoop 4 and the connection module 3 are connected by the connecting segment 422 and the nut 423 of the bolt 42. The connecting segment 422 passes through the limiting hole 32b, and the nut 423 is in the limiting groove 33b.

[0034] The limiting hole 32b and the limiting groove 33b are used for: restricting all degrees of freedom of movement of the bolt 42 relative to the base 31. That is to say: there is an interference fit between the connecting segment 422 and the limiting hole 32b, restricting the left and right movement and up and down movement of the bolt 42 relative to the base 31; the limiting groove 33b is in a convex shape, the connecting segment 422 passes through the narrower part of the limiting groove 33b, the nut 423 is in the wider part of the limiting groove 33b, and the thickness of the nut 423 is equal to the dimension of the wider part in the front and rear directions, restricting the front and rear movement of the bolt 42 relative to the base 31.

[0035] Restrict all degrees of freedom of movement of the bolt 42 relative to the base 31, while the bolt 42 does not interfere with the movement of the abutting block 32 relative to the base 31 and the movement of the slider 33 relative to the base 31.

[0036] In addition, between the nut 423 and the limiting groove 33b, it can also be designed to restrict the rotation of the bolt 42 relative to the base 31. More specifically, the nut 423 is rectangular.

[0037] When the hoop 4 is connected to the connection module 3, it can be found that in addition to the above-mentioned "the base 31 fits against the front inner wall 2a2 of the chute 2a, and when the abutting block 32 moves backward, it can abut against the rear inner wall 2a3 of the chute 2a, so that the connection module 3 and the chute 2a are relatively fixed", the fixing method between the connection module 3 and the chute 2a can also be: when the abutting block 32 moves backward and fits into the substrate 41, the abutting block 32 and the substrate 41 respectively abut against the rear inner wall 2a3 and the rear outer wall 2a4 of the chute 2a.

[0038] Please refer to Figure 2 and Figure 3 In some embodiments, the base 31 fits against the front inner wall 2a2 of the chute 2a, and the substrate 41 fits against the rear outer wall 2a4 of the chute 2a.

[0039] That is, it combines two fixing methods between the connection module 3 and the chute 2a, making it more stable. When the abutting block 32 switches to release the rear inner wall 2a3 of the chute 2a, the relative movement between the connection module 3 and the chute 2a is also more stable.

[0040] The movement of the slider 33 towards the direction close to the abutting block 32 is limited. That is, after the abutting block 32 abuts against the rear inner wall 2a3 of the chute 2a, the slider 33 can no longer move closer to the abutting block 32. By designing the length of the limiting groove 33b, the nut 423 and the limiting groove 33b can be ensured not to separate in this direction. However, the movement of the slider 33 away from the abutting block 32 lacks limitation, and the connection module 3 cannot be directly observed inside the chute 2a. During operation, it may be misoperated, causing the nut 423 and the limiting groove 33b to separate.

[0041] Please refer to Figure 7 In some embodiments, the slider 33 has a blocking portion 33c on one side of the limiting groove 33b. The blocking portion 33c is used to: when the slider 33 moves away from the abutting block 32, restrict the nut 423 from leaving the limiting groove 33b.

[0042] A connection module 3 is added between the sliding groove 2a and the hoop 4. When it is necessary to adjust the position of the sign panel 2 vertically, loosen the two adjusting nuts 44. The connection module 3 and the sliding groove 2a remain relatively fixed, and the sign panel 2, the two connection modules 3, and the two hoops 4 move up and down together to adjust the position. When it is necessary to adjust the position of the sign panel 2 horizontally or replace the sign panel 2, the driving part moves the slider 33 in a direction away from the abutting block 32, and the abutting block 32 switches to release the inner wall 2a3 of the sliding groove 2a, so that the connection module 3 and the sliding groove 2a move relative to each other. The hoop 4 and the seamless steel pipe 1 remain relatively fixed, and the sign panel 2 moves horizontally to adjust the position. The sign panel 2 can also be removed from the connection module 3 for replacement.

[0043] Please refer to Figure 8 , in some embodiments, the road traffic sign installation structure further includes: a solar panel 5 and a warning light 6. For the single-column type and the double-column type, both are installed at the top of the seamless steel pipe 1. For the cantilever type, both are installed on the outer wall of the seamless steel pipe 1.

[0044] The solar panel 5 supplies power to the warning light 6. When the environment is relatively dark, the warning light 6 lights up to facilitate noticing the sign panel 2.
