Description

Technical Field

[0001] The utility model relates to the field of road guardrail auxiliary components, in particular to a road guardrail which is easy to assemble. Background Art

[0002] Guardrails are also called safety barriers. Guardrails are mainly used for the protection and preservation of personal safety and equipment facilities in residential areas, highways, commercial areas, public places and other places. Guardrails can be seen everywhere in our lives. Road guardrails are a type of guardrail. Road guardrails are mainly used for isolation of urban traffic arteries, green belts in the middle of highways, bridges and secondary roads.

[0003] At present, when designing road guardrails, they are usually composed of guardrail poles and columns. When assembling at the construction site, bolts are usually used to assemble the guardrail poles and columns together. Since there are many locations where bolts need to be installed, the installation time is long and the assembly is very inconvenient. At the same time, when combining adjacent guardrail sections, both are placed freely on the ground without being connected. This method will cause the guardrail section to have poor stability during use and be easy to tip over. There is also a method in which the two are connected together by tools such as bolts. This method will make it inconvenient to quickly replace the individually damaged guardrail section at a later time. Utility Model Content

Specifically, when the positions of the guardrail post bodies at both sides are fixed, when the locking rods are vertically disengaged from all the locking holes, the guardrail cross bar assembly can be contracted and adjusted to enable the plug plate to be smoothly disengaged from the slot, thereby ensuring that the guardrail post body can be smoothly separated from the guardrail cross bar assembly. At the same time, the guardrail cross bar assembly can be extended to enable the plug plate to be smoothly slidably matched and inserted into the slot, thereby ensuring that the guardrail post body can be smoothly combined with the guardrail cross bar assembly. Specifically, when the lower part of the guardrail post body is assembled and connected with the guardrail base body, since the lower part of the guardrail post body is vertically slidably matched with the matching groove at the beginning,At the same time, the limiting rod and the limiting hole are horizontally slidably matched. At this time, the guardrail post body can be detachably fixed to the top of the guardrail base body by vertically sliding cooperation between the lower part of the guardrail post body and the matching groove of the disassembly and assembly assembly and the limiting rod and the limiting hole are horizontally slidably matched.

When separating the guardrail base body from the guardrail column body, the guardrail column body and the corresponding guardrail crossbar assembly should be separated first, and then the handle only needs to be pulled outward and the limit rod can be disengaged from the limit hole by the way of the spring being stretched. Then, the limit rod can be pulled outward to make the lower part of the guardrail column body slide vertically out of the matching groove and separate the guardrail column body from the guardrail base body.

[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0038] See also Figure 1-Figure 11As shown, the utility model provides a road guardrail that is easy to assemble, including a guardrail post body 2 and a guardrail base body 3. The number of guardrail post bodies 2 of each guardrail section is two and they are respectively erected on both sides. The guardrail post bodies 2 at both sides of each guardrail section are detachably connected with multiple guardrail cross bar assemblies 1 with length telescopic adjustment and locking functions through a combined connection assembly 5. Specifically, the guardrail cross bar assembly 1 includes a guide rod 105 and a sleeve 103. The guide rod 105 is horizontally placed between the guardrail post bodies 2 at both sides. The two ends of the guide rod 105 are coaxially sleeved with sleeves 103 in a coaxial sliding fit manner. The inner ends of the sleeves 103 at the two sides are close to each other and are radially meshed with locking screws 104, and the inner ends of the locking screws 104 can be pressed against the periphery of the guide rod 105. The sleeves at both sides The outer ends of 103 that are away from each other are fixed with a vertically arranged mounting plate 101 through a connecting sleeve 102. Preferably, the sleeve 103 is coaxially interference fit with the corresponding connecting sleeve 102, and the connecting sleeve 102 is welded to the side end face of the corresponding mounting plate 101, and the mounting plate 101 is detachably connected to the corresponding guardrail column body 2 through the combined connecting component 5. The purpose of such a setting is that since the guardrail cross bar assembly 1 has the function of length telescopic adjustment and locking, the guardrail cross bar assembly 1 can be used to improve the flexibility of use of the guardrail cross bar assembly 1 during on-site deployment through the telescopic adjustment method of the guardrail cross bar assembly 1. At the same time, the telescopic adjustment method of the guardrail cross bar assembly 1 also facilitates the smooth sliding fit between the plug plate 505 and the slot 506 and the smooth sliding out of the plug plate 505 from the slot 506, thereby ensuring that the guardrail cross bar assembly 1 and the guardrail column body 2 can successfully complete the combination and disassembly operations.

[0039] See also Figure 1-Figure 5As shown, the combined connection component 5 between the guardrail post body 2 and the guardrail crossbar component 1 is specifically as follows: the combined connection component 5 includes a plug plate 505 and a slot 506, and the mounting plate 101 is horizontally extended and fixed with the plug plate 505 at the side end surface close to the corresponding guardrail post body 2, and the guardrail post body 2 is provided with a plurality of slots 506 in the transverse direction on the outer surface close to the mounting plate 101, and the number of the slots 506 corresponds to the plug plates 505, and the plug plates 505 pass through the corresponding slots 506 in a transverse sliding fit and enter the interior of the guardrail post body 2, and the cross-sectional shapes of the plug plates 505 and the slots 506 along the longitudinal vertical plane are preferably rectangular, so that the plug plates 505 and the slots 506 have a good guiding and correcting design when they slide and fit in the transverse direction, At the same time, it is convenient to vertically open the locking hole 503 at the part where the plug plate 505 extends into the guardrail column body 2. The part of the plug plate 505 located inside the guardrail column body 2 is vertically opened with a locking hole 503, and the locking holes 503 are all through holes. The locking holes 503 of the plug plate 505 corresponding to the same guardrail column body 2 are all vertically coaxially contrasted, and the locking holes 503 corresponding to the same guardrail column body 2 are all penetrated by the same locking rod 504, and the locking rod 504 is coaxially detachably connected with the locking hole 503. The advantage of such a setting is that the guardrail crossbar assembly 1 is connected by the plug plate 5 of the combined connection assembly 5 05 is detachably connected to the guardrail column body 2 in a manner of vertical sliding cooperation with the slot 506 and vertical coaxial cooperation of the locking rod 504 with all the locking holes 503, so that it is convenient to quickly combine the guardrail cross bar assembly 1 and the guardrail column body 2 on site to form a guardrail section for use. At the same time, it is only necessary to make the locking rod 504 disengage from the locking hole 503 so that the plug plate 505 can be laterally disengaged from the slot 506 to separate the guardrail cross bar assembly 1 from the guardrail column body 2, so that it is convenient to separate the guardrail cross bar assembly 1 from the guardrail column body 2 at a later time and then replace the guardrail cross bar assembly 1 or the guardrail column body 2 separately.

[0040] See also Figure 4-Figure 7As shown, disassembly and assembly components 4 are installed on both sides of the top of the guardrail base body 3, and the two guardrail column bodies 2 close to each other in adjacent guardrail sections are detachably connected to the guardrail base body 3 through the disassembly and assembly components 4, so as to connect the two guardrail column bodies 2 close to each other in adjacent guardrail sections through the guardrail base body 3. Specifically, the disassembly and assembly components 4 include limiting holes 405 and matching grooves 404. The lower parts of the two guardrail column bodies 2 close to each other in adjacent guardrail sections are both provided with limiting holes 405 in the transverse direction on the outer end faces away from each other, and the two The limiting holes 405 at the side positions are horizontally coaxially matched, and matching grooves 404 are vertically opened on both sides of the top surface of the guardrail base body 3, and the lower parts of the two guardrail column bodies 2 close to each other in the adjacent guardrail sections correspond to the matching grooves 404 one by one and slide vertically. The end surfaces of both sides of the guardrail base body 3 are horizontally opened with mounting holes 403, and the mounting holes 403 are vertically connected with the corresponding matching grooves 404, and the mounting holes 403 are horizontally coaxially matched with the limiting holes 405 on the same side, and the mounting holes 403 are horizontally slidably matched with the limiting rods 406, and the limiting rods at the positions on both sides The inner ends of the 406 close to each other are lateraly slidably matched with the corresponding limiting holes 405, and the outer ends of the limiting rods 406 at the two sides are coaxially fixed with handles 401, and the part of the limiting rod 406 located between the corresponding handle 401 and the outer end surface of the guardrail base body 3 is coaxially matched with a spring 402, and the two ends of the spring 402 are respectively connected to the corresponding handle 401 and the outer end surface of the guardrail column body 2. The purpose of this arrangement is to vertically slide and match the limiting rod 4 through the lower part of the guardrail column body 2 and the matching groove 404 of the disassembly assembly assembly 4 06 and the limiting hole 405 can slide horizontally to fix the guardrail column body 2 on the top of the guardrail base body 3, so that the guardrail column body 2 and the guardrail base body 3 can be quickly combined together on site to complete the fixation. At the same time, only the limiting rod 406 needs to be pulled out of the limiting hole 405 to make the lower part of the guardrail column body 2 slide vertically out of the matching groove 404 to separate the guardrail column body 2 and the guardrail base body 3 from each other, so that the guardrail column body 2 can be separated from the guardrail base body 3 at a later time and the guardrail column body 2 can be replaced separately.

[0041] See also Figure 1-Figure 7As shown, the guardrail post body 2 and the combined connection assembly 5 are optimized as follows. Specifically, in the guardrail post body 2, the guardrail post body 2 is a hollow post, and the horizontal cross-sectional shape of the guardrail post body 2 is a rectangle, so that the slot 506 can be smoothly opened on the outer end surface of the guardrail post body 2. The top of the guardrail post body 2 is coaxially and detachably installed with a decorative plug 201 for sealing the top opening. Preferably, the lower outer periphery of the decorative plug 201 is frictionally matched with the top inner periphery of the guardrail post body 2, and the decorative plugs 201 of the two guardrail post bodies 2 of adjacent guardrail sections do not contact each other. Such a setting is convenient for increasing the overall aesthetic effect of the guardrail post body 2, and at the same time, it is convenient to hide the locking rod 504 inside the guardrail post body 2 by setting the decorative plug 201.

[0042] Specifically, in the combined connection assembly 5, the locking rod 504 is a screw rod, the locking holes 503 are all threaded through holes, and the locking rod 504 and the locking hole 503 are both detachably connected by coaxial threaded fit. In this case, the locking rod 504 and the locking hole 503 can be quickly assembled and disassembled by twisting the locking rod 504. Alternatively, the locking rod 504 can be a hard rubber cylindrical rod, the locking holes 503 can be smooth circular through holes, and the locking rod 504 and the locking hole 503 can be detachably connected by coaxial tension fit. In this case, the locking rod 504 and the locking hole 503 can be quickly assembled and disassembled by pressing or pulling the locking rod 504 with axial force.

[0043] Further, optionally, the end surfaces of the mounting plate 101 and the guardrail column body 2 that are close to each other are in close contact, so that when the plug plate 505 slides along the slot 506 to the locking hole 503 corresponding to the same guardrail column body 2 and is vertically coaxially compared, it can be clearly prompted by the way that the end surfaces of the mounting plate 101 and the guardrail column body 2 that are close to each other are in close contact. The top of the locking rod 504 is coaxially fixed with an end plate 502, and the end plate 502 is pressed against the top surface of the plug plate 505 at the top position, and the top surface of the end plate 502 is fixedly installed with a pull ring 501 for hand-held force application, preferably the highest position of the pull ring 501 is lower than the lowest position of the decorative plug 201, so that the two do not interfere with each other, and at the same time, the way of setting the pull ring 501 is also convenient to use as a force application point to drive the locking rod 504 and the locking hole 503 to be combined and separated.

[0044] See also Figure 1-Figure 7As shown, the disassembly and assembly assembly 4 and the guardrail base body 3 are optimized as follows. Specifically, in the disassembly and assembly assembly 4, the horizontal cross-sectional shape of the matching groove 404 is rectangular, the matching groove 404 is a blind groove with a depth of not less than 10 cm, and the bottom end surface of the guardrail post body 2 is in close contact with the bottom of the matching groove 404. This arrangement facilitates the guardrail post body 2 to have a good positioning and guiding design when it slides vertically along the matching groove 404, and at the same time facilitates the guardrail post body 2 to extend into the matching groove 404 to a sufficient depth to improve the reliability of the cooperation between the two. In the process of the guardrail post body 2 sliding vertically along the matching groove 404, when the limit hole 405 slides down with the guardrail post body 2 to be coaxial with the limit hole 405, it can be clearly prompted by the way that the bottom end surface of the guardrail post body 2 is in close contact with the bottom of the matching groove 404.

[0045] Specifically in the guardrail base body 3, the bottom surface of the guardrail base body 3 extends horizontally and is fixed with a connecting plate 301 for installation on the road surface, and the front and rear edges of the connecting plate 301 are vertically provided with multiple connecting holes 302. The purpose of this arrangement is to allow the guardrail base body 3 to be installed and fixed to the road surface layout position by adding anchor bolts to the road surface through the connecting holes 302 of the connecting plate 301.

[0046] With the above structure, specifically during the process of assembling and using the guardrail section, initially, the plug plates 505 at both ends of the guardrail crossbar assembly 1 are respectively slidably matched with the slots 506 of the guardrail post body 2 at both sides, and at the same time, the locking rod 504 is coaxially matched with the locking hole 503 of the same guardrail post body 2. At this time, the guardrail crossbar assembly 1 can be detachably connected to the guardrail post body 2 by vertically sliding the plug plates 505 of the combined connection assembly 5 with the slots 506 and vertically coaxially matching the locking rod 504 with all the locking holes 503. The fixed combination of the guardrail crossbar assembly 1 and the guardrail post body 2 is simple and easy to operate, which makes it easy to quickly combine the guardrail crossbar assembly 1 and the guardrail post body 2 on site to form a guardrail section for use, and subsequently When it is necessary to separate the guardrail crossbar assembly 1 from the guardrail post body 2, remove the decorative plug 201, then hold the pull ring 501 at the end and apply force to make the locking rod 504 move vertically out of the locking hole 503, then only after the locking rod 504 is out of the locking hole 503, the plug plate 505 can be horizontally out of the slot 506 to separate the guardrail crossbar assembly 1 from the guardrail post body 2. The separation method of the guardrail crossbar assembly 1 and the guardrail post body 2 is simple and easy to operate, and then it is convenient to separate the guardrail crossbar assembly 1 from the guardrail post body 2 at a later time, and then replace the guardrail crossbar assembly 1 or the guardrail post body 2 separately, and at the same time facilitate the transportation of the guardrail crossbar assembly 1 and the guardrail post body 2. Since the guardrail crossbar assembly 1 has the function of length telescopic adjustment and locking, the specific After loosening the locking screw 104, the outermost end position of the sleeve 103 can be adjusted by sliding the sleeve 103 laterally along the guide rod 105, so as to adjust the overall length of the guardrail crossbar assembly 1. When the adjustment is completed, the locking screw 104 can be tightened to press it against the outer periphery of the guide rod 105 to quickly lock it. In this way, the telescopic adjustment method of the guardrail crossbar assembly 1 can improve the flexibility of the guardrail crossbar assembly 1 during on-site deployment. At the same time, the telescopic adjustment method of the guardrail crossbar assembly 1 also facilitates the smooth sliding cooperation between the plug plate 505 and the slot 506 and the smooth sliding out of the plug plate 505 from the slot 506, thereby ensuring that the guardrail crossbar assembly 1 and the guardrail column body 2 can be smoothly combined and disassembled. Specifically, at both sides When the position of the guardrail post body 2 is fixed, after the locking rod 504 vertically disengages from all the locking holes 503, the guardrail cross bar assembly 1 can be contracted and adjusted to enable the plug plate 505 to smoothly disengage from the slot 506, thereby ensuring that the guardrail post body 2 can be smoothly separated from the guardrail cross bar assembly 1. At the same time, the guardrail cross bar assembly 1 can be extended to enable the plug plate 505 to smoothly slide and fit with the slot 506 and insert, thereby ensuring that the guardrail post body 2 can be smoothly combined with the guardrail cross bar assembly 1. Specifically, when the lower part of the guardrail post body 2 is combined and connected with the guardrail base body 3, at the beginning, the lower part of the guardrail post body 2 is vertically slidably matched with the matching groove 404, and the limiting rod 406 is horizontally slidably matched with the limiting hole 405.At this time, the guardrail post body 2 can be detachably fixed to the top of the guardrail base body 3 by means of vertical sliding cooperation between the lower part of the guardrail post body 2 and the matching groove 404 of the disassembly and assembly assembly 4 and the horizontal sliding cooperation between the limit rod 406 and the limit hole 405. The fixing and combining method of the guardrail post body 2 and the guardrail base body 3 is simple and easy to operate, which makes it easy to quickly combine the guardrail post body 2 and the guardrail base body 3 together on site to complete the fixation. At the same time, it is also easy to realize the connection of adjacent guardrail sections by combining and connecting adjacent guardrail post bodies 2 with the guardrail base body 3. When the guardrail post body 2 and the guardrail base body 3 need to be separated later, First, the guardrail post body 2 and the corresponding guardrail crossbar assembly 1 should be separated, and then the handle 401 only needs to be pulled outward and the limit rod 406 can be disengaged from the limit hole 405 by stretching the spring 402. Then, the limit rod 406 can be pulled outward to make the lower part of the guardrail post body 2 slide vertically out of the matching groove 404 to separate the guardrail post body 2 and the guardrail base body 3 from each other. The separation method of the guardrail post body 2 and the guardrail base body 3 is simple and easy to operate, which makes it convenient to replace the guardrail post body 2 separately after separating the guardrail post body 2 and the guardrail base body 3 at a later time, and at the same time facilitates the transportation of the guardrail post body 2 and the guardrail base body 3.
