Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a fence for closing a municipal road surface. Background Art

[0002] During the construction or maintenance of municipal roads, in order to ensure construction safety and smooth traffic, it is necessary to temporarily close the municipal road surface. In order to alert vehicles or pedestrians, the construction party generally uses fences on the municipal road surface to isolate and warn both sides to prevent pedestrians from entering the construction site. Fences are guardrails, which are a kind of railings that surround and block the surroundings. They have the functions of separation, blocking and shielding.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the height of the fence used for closing municipal roads in the prior art is fixed and cannot be adjusted according to different construction environments, and the fence is difficult to disassemble and is not convenient to move and transport. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a fence for closing a municipal road surface.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a fence for closing a municipal road surface, comprising two bases, each of which has a column fixed on the upper surface of the base, and the two columns are jointly provided with a plurality of horizontal bars slidably connected to the columns, and each of the side walls of the columns is provided with a plurality of limit grooves, and each of the horizontal bars is equipped with two groups of limit components for limiting the horizontal bars, and each group of the limit components includes a limit rod that is penetrated and slidably connected to the side wall of the horizontal bar and a pulling block fixed to one end of the limit rod away from the limit groove, and the limit rod is plugged into the limit groove.

[0006] By adopting the above technical solution, when the height of the horizontal rail needs to be adjusted, the staff only needs to disengage the limit rod from the limit groove by pulling the block, and then slide the horizontal rail on the column to a suitable position, and insert the limit rod into the limit grooves of different heights to limit the horizontal rail. This not only can adjust the spacing between the horizontal rails, but also facilitates the adjustment of the height of the fence according to different construction environments. When disassembly is required, the staff only needs to pull the limit rod out of the limit groove and move it upward out of the column, which is convenient for moving and transporting the fence.

[0007] Furthermore, each of the side walls of the horizontal bar is provided with a spring groove, each of the spring grooves is provided with a clamping spring, one end of each of the clamping springs is fixed to the inner wall of the spring groove, and the other end of each of the clamping springs is fixed to the side wall of the pulling block.

[0008] By adopting the above technical solution, the pulling block keeps the limit rod in the plugged state with the limit groove under the elastic force of the pressing spring, thereby reducing the probability of the limit rod detaching from the limit groove and causing the cross bar to move.

[0009] Furthermore, a yielding portion cooperating with the bottom wall of the limiting groove is formed on the lower surface of each limiting rod.

[0010] By adopting the above technical solution, the horizontal rail can squeeze the limit rod into the horizontal rail during the upward movement, eliminating the tedious operation of the staff to manually operate the pulling block, making it convenient to quickly raise the height of the horizontal rail.

[0011] Furthermore, the two side walls of the pulling block are fixed by a handle.

[0012] By adopting the above technical solution, the handle connects the two pulling blocks, so that the staff can pull the pulling blocks on both sides at the same time through the handle, eliminating the tedious operation of controlling the two pulling blocks with both hands, which is conducive to moving the horizontal bar through the handle.

[0013] Furthermore, a limiting block is arranged at the upper end of each of the columns, and a stud threadedly connected to the column is fixed at the bottom of each of the limiting blocks.

[0014] By adopting the above technical solution, when there is no need to remove the horizontal rail, the limit block prevents the horizontal rail from detaching upward from the column. When the horizontal rail needs to be removed, the staff only needs to rotate the limit block to disengage the stud from the column, thereby facilitating the removal of the horizontal rail from the top of the column.

[0015] Furthermore, a plurality of universal wheels are provided at the bottom of each base.

[0016] By adopting the above technical solution, the laborious operation of manually moving the fence is eliminated, and the fence can be easily moved by the universal wheels.

[0017] Furthermore, a slide groove is provided at the bottom of each base, and a universal wheel lifting assembly is installed on each base. Each group of the lifting assemblies includes a threaded rod that is penetrated and threadedly connected to the base, a star-shaped handle fixed to the upper end of the threaded rod, and a mounting plate that is rotatably connected to the lower end of the threaded rod and slidably connected to the inner wall of the slide groove. The universal wheel is fixed to the bottom of the mounting plate.

[0018] By adopting the above technical solution, when the fence is moved to the required position, the staff needs to rotate the threaded rod through the star-shaped handle. Since the threaded rod is rotatably connected to the mounting plate, and the mounting plate is slidably connected to the slide groove, the mounting plate moves upward and the universal wheel enters the slide groove, breaking away from contact with the ground, thereby enhancing the stability of the fence when in use.

[0019] Furthermore, a non-slip pad is fixed to the bottom of each base.

[0020] By adopting the above technical solution, the anti-skid pad is made of rubber material, and its surface has a large friction coefficient. The provision of the anti-skid pad increases the friction force at the bottom of the base and reduces the probability of displacement of the base. In addition, the anti-skid pad also reduces the wear on the bottom of the base.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when the height of the horizontal rail needs to be adjusted, the staff only needs to disengage the limit rod from the limit groove by pulling the block, then slide the horizontal rail on the column to a suitable position, and insert the limit rod into the limit grooves of different heights to limit the horizontal rail. This can not only adjust the spacing between the horizontal rails, but also facilitate the adjustment of the height of the fence according to different construction environments. When disassembly is required, the staff only needs to pull the limit rod out of the limit groove and move it upward out of the column, which is convenient for moving and transporting the fence;

[0023] 2. In the present application, the pull block keeps the limit rod plugged into the limit slot under the elastic force of the tightening spring, which reduces the probability of the limit rod detaching from the limit slot and causing the crossbar to move;

[0024] 3. In the present application, when the fence is moved to the required position, the staff needs to rotate the threaded rod through the star-shaped handle. Since the threaded rod is rotatably connected to the mounting plate, and the mounting plate is slidably connected to the slide groove, the mounting plate moves upward and the universal wheel enters the slide groove, breaking away from contact with the ground, thereby enhancing the stability of the fence when in use.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] like Figure 1-3 As shown, an embodiment of the present application discloses a fence for closing a municipal road surface, including a base 1, a column 2, a horizontal bar 3 and a limiting component 4.

[0031] The base 1 is a rectangular parallelepiped structure, and two bases 1 are provided. The upright posts 2 are vertically arranged rectangular rod-shaped structures, and two upright posts 2 are provided. The two upright posts 2 are respectively fixed on the upper surfaces of the two bases 1, and the side walls of each upright post 2 are provided with a plurality of limit grooves 21. The horizontal bar 3 is a horizontally arranged rectangular rod-shaped structure, and the horizontal bar 3 is sleeved on the two upright posts 2 and slidably connected with the upright posts 2. There are a plurality of horizontal bars 3, and the side walls of each horizontal bar 3 are provided with a spring groove 31.

[0032] The limiting assembly 4 is installed on the horizontal rail 3 and is used to limit the horizontal rail 3. Two sets of limiting assemblies 4 are arranged on each horizontal rail 3, and each set of limiting assemblies 4 includes a limiting rod 41, a pulling block 42 and a tightening spring 43. The limiting rod 41 is a horizontally arranged rectangular rod-shaped structure, which is penetrated and slidably connected to the side wall of the horizontal rail 3, and the limiting rod 41 is plugged and matched with the limiting groove 21. The tightening spring 43 is arranged in the spring groove 31, one end of the tightening spring 43 is fixed to the inner wall of the spring groove 31, and the other end of the tightening spring 43 is fixed to the side wall of the pulling block 42.

[0033] When the height of the cross bar 3 needs to be adjusted, the staff only needs to disengage the limit rod 41 from the limit groove 21 by pulling the block 42, then slide the cross bar 3 on the column 2 to a suitable position, and then release the pulling block 42 to allow the limit rod 41 to be inserted into the limit groove 21 of different heights under the elastic force of the spring, thereby limiting the cross bar 3. Not only can the spacing between the cross bars 3 be adjusted, but it is also convenient to adjust the height of the fence according to different construction environments. When disassembly is required, the staff only needs to pull the limit rod 41 out of the limit groove 21 and then move it upward out of the column 2, which is convenient for moving and transporting the fence. The pulling block 42 keeps the limit rod 41 plugged into the limit groove 21 under the elastic force of the pressing spring 43, reducing the probability of the limit rod 41 detaching from the limit groove 21 and causing the cross bar 3 to move.

[0034] In order to facilitate the rapid increase in the height of the horizontal rail 3, a yielding portion 411 is provided on the lower surface of each limit rod 41 and cooperates with the inner bottom wall of the limit groove 21. The setting of the yielding portion 411 allows the limit rod 41 to be squeezed into the horizontal rail 3 during the upward movement of the horizontal rail 3, eliminating the tedious operation of the staff to manually operate the pulling block 42, thereby facilitating the rapid increase in the height of the horizontal rail 3.

[0035] In order to avoid the tedious operation of controlling the two pulling blocks 42 with two hands, the side walls of the two pulling blocks 42 are fixed by a handle 5, and the handle 5 connects the two pulling blocks 42, so that the staff can pull the pulling blocks 42 on both sides at the same time through the handle 5, thereby avoiding the tedious operation of controlling the two pulling blocks 42 with two hands, which is conducive to moving the horizontal bar 3 through the handle 5.

[0036] In order to limit the horizontal rail 3, a limiting block 6 is provided at the upper end of each column 2, and a stud 7 threadedly connected to the column 2 is fixed at the bottom of each limiting block 6. When there is no need to disassemble the horizontal rail 3, the limiting block 6 prevents the horizontal rail 3 from detaching upward from the column 2. When the horizontal rail 3 needs to be disassembled, the staff only needs to rotate the limiting block 6 to disengage the stud 7 from the column 2, thereby facilitating the removal of the horizontal rail 3 from the top of the column 2.

[0037] In order to facilitate the movement of the fence, a plurality of universal wheels 8 are provided at the bottom of each base 1. The provision of the universal wheels 8 eliminates the laborious operation of manually moving the fence, and facilitates the movement of the fence through the universal wheels 8.

[0038] In order to enhance the stability of the fence when in use, a slide groove 11 is provided at the bottom of each base 1, and a lifting assembly 9 is installed on each base 1 for lifting the universal wheel 8. Each lifting assembly 9 includes a threaded rod 91, a star-shaped handle 925 and a mounting plate 93. The threaded rod 91 is a vertically arranged rod-shaped structure, which is penetrated and arranged on the base 1 and threadedly connected. The star-shaped handle 925 is fixed to the upper end of the threaded rod 91, and the axis of the star-shaped handle 925 coincides with the axis of the threaded rod 91. The mounting plate 93 is a rectangular plate-shaped structure, which is rotatably connected to the lower end of the threaded rod 91, and the mounting plate 93 is slidably connected to the inner wall of the slide groove 11, and the universal wheel 8 is fixed to the bottom of the mounting plate 93. When the fence is moved to the required position, the staff needs to rotate the threaded rod 91 through the star-shaped handle 925. Since the threaded rod 91 is rotatably connected to the mounting plate 93, and the mounting plate 93 is slidably connected to the slide groove 11, the mounting plate 93 moves upward and the universal wheel 8 enters the slide groove 11 and breaks away from the contact with the ground, thereby enhancing the stability of the fence when in use.

[0039] In order to reduce the probability of displacement of the base 1, an anti-skid pad 10 is fixed to the bottom of each base 1. The anti-skid pad 10 is made of rubber material and its surface has a large friction coefficient. The provision of the anti-skid pad 10 increases the friction force at the bottom of the base 1, thereby reducing the probability of displacement of the base 1. In addition, the anti-skid pad 10 also reduces the wear on the bottom of the base 1.

[0040] The operating principle of a municipal road closure fence in the present embodiment is as follows: when the height of the cross bar 3 needs to be adjusted, the staff only needs to disengage the limit rod 41 from the limit groove 21 by pulling the block 42, and then slide the cross bar 3 on the column 2 to a suitable position, and then release the pulling block 42 to allow the limit rod 41 to be inserted into the limit groove 21 of different heights under the elastic force of the spring, thereby limiting the cross bar 3, which can not only adjust the spacing between the cross bars 3, but also facilitate the adjustment of the height of the fence according to different construction environments. When disassembly is required, the staff only needs to pull the limit rod 41 out of the limit groove 21 and then move it upward out of the column 2, which is convenient for moving and transporting the fence. The pulling block 42 keeps the limit rod 41 plugged into the limit groove 21 under the elastic force of the pressing spring 43, reducing the probability of the limit rod 41 detaching from the limit groove 21 and causing the cross bar 3 to move.

[0041] 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.
