Description

Technical Field

[0001] The invention mainly relates to the field of road traffic sign manufacturing, and in particular to a combinable frame profile for road traffic signs. Background Art

[0002] With the development of road traffic, beautification of roads, and increased requirements for traffic safety, more and more road traffic luminous signs are being used. In the prior art, some traffic luminous signs use transparent sign panels, with a reflective film with traffic instruction graphics pasted on the front of the sign panel, and a light source board on the back of the sign panel. The front side can serve as a normal indication during the day or a reflective indication at night, and at the same time, when the back side is luminous at night, it can also transmit light so that the front side serves as an indication.

[0003] In the prior art, some traffic luminous signs need to light up not only the middle image and text, but also the image and text part around the border of the sign. To this end, some prior art uses a sign border with a light trough, and the light board in the light trough is used to light up the image and text part around the border of the sign. However, there are the following defects:

[0004] 1. The existing frame structures are too simple and cannot be combined or split. After some ordinary traffic signs have been used for a period of time, they may need to be changed to traffic signs that can light up the edge text. At this time, the original ordinary signs can only be abolished and the sign frames with light troughs can be used to make a new set of traffic signs, which wastes resources very seriously. In addition, the re-production is time-consuming, labor-intensive, and inefficient, and the change cannot be achieved as soon as possible.

[0005] Second, the existing frame is arranged in parallel with the first through hole, the second through hole and the installation groove, and the light bar is placed in the installation groove. The first through hole and the second through hole are closed through holes. Two adjacent frames are connected by a special matching elbow. Both ends of the elbow are provided with two flanges specially matched with the first through hole and the second through hole. When connecting, both flanges are inserted into the first through hole and the second through hole. Since the first through hole and the second through hole are closed through holes, the flanges cannot be seen after insertion. The fixing effect of this structural form is not good. The inserted flange cannot form a stable connection with the frame well. Since the flange cannot be seen, there is no way to find the places where the two are not connected in place (for example, which surfaces are not in contact with each other for tightening, etc.) and make improvements. This makes the connection unstable and easily causes structural problems of traffic signs. Whether it is transported or hoisted at high altitude, it is very easy to loosen or even fall off, which seriously threatens the safety of the operation. And due to the instability of this structure, even if no problems are found during installation, with the outdoor wind and rain of the traffic sign, there is a high risk of falling off, which seriously affects the safety of pedestrians and vehicles on the road.

[0006] 3. The existing frame setting is unreasonable. When the sign needs to be hoisted, the existing technology is to set the hoisting workpiece on the upper frame. First, before the adjacent frames are welded, several holes are punched on the frame, and then several screws are inserted into the closed first through hole and the second through hole through the end of the frame, so that the screws extend out of the hole from bottom to top, and then several lifting rings are threadedly connected with the several screws that extend out. Then the frame is welded to death, which makes it impossible to remove the screws from the frame. There are several problems: first, the punching accuracy requirements are high, the cost is high, and it is time-consuming and labor-intensive. Second, this method prevents the screws from being displaced. During transportation and hoisting, due to the influence of the installation environment or the influence of the transportation equipment, the hoisting point may need to be changed. For example, sometimes it needs to be transported horizontally, and sometimes the sign needs to be tilted at a certain angle for transportation, so that the transportation can be completed quickly. However, since the screws in the existing structure are limited in the hole, it cannot be flexibly adjusted, and it cannot meet the operation requirements well, and the operation risk is greatly increased. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a combinable frame profile for road traffic signs which has a simple and compact structure, can be flexibly assembled and transformed according to needs, has good connection stability and high safety.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A combinable frame profile for road traffic signs, comprising a first profile and a second profile that match each other, wherein the first profile is provided with a light bar installation groove with an upper opening for installing the light bar to illuminate the edge graphic portion of the road traffic sign, and the first profile and the second profile are detachably assembled and connected via a sliding limit mechanism so that when assembled together, they can be used to make a road traffic sign with an edge graphic portion that needs to be illuminated / or when not assembled, only the second profile is used to make a road traffic sign without an edge graphic portion that needs to be illuminated.

[0010] As a further improvement of the present invention, the sliding limiting mechanism includes a second limiting groove axially opened on the side wall of the second profile, and the sliding limiting mechanism also includes a T-shaped limiting strip axially protruding on the side wall of the first profile. The second limiting groove is used to allow the T-shaped limiting strip to be inserted and clamped in the second limiting groove to enable the first profile and the second profile to be assembled and connected, or to allow the road traffic sign hoisting workpiece to be adjustably limited and slid in the second limiting groove when not assembled to facilitate the road traffic sign hoisting operation.

[0011] As a further improvement of the present invention, the first profile includes a base plate, and the base plate is respectively provided with a first side plate and a second side plate facing upward on both sides along the axial direction. The base plate, the first side plate and the second side plate together form a light bar mounting groove, and the outer surface of the first side plate is provided with two upper and lower oppositely arranged bending parts, so as to form a first limiting groove opened along the axial direction on the outer surface of the first side plate. The first limiting groove is used to enable the road traffic sign hoisting workpiece to be movably limited and slid in the first limiting groove when the first profile and the second profile are assembled and connected, so as to facilitate the road traffic sign hoisting operation.

[0012] As a further improvement of the present invention, a first bearing plate is provided at the top end of the first side panel, and a second bearing plate is provided at the top end of the second side panel for bearing a transparent plate for fixing road traffic signs, the distance between the first bearing plate and the second bearing plate is smaller than the inner diameter width of the bottom surface of the light bar mounting groove, and two parallel light bar limiting ribs arranged along the axial direction are provided on the bottom surface of the light bar mounting groove corresponding to the distance between the first bearing plate and the second bearing plate, so as to insert the light bar between the two light bar limiting ribs and then limit and install it in the light bar mounting groove.

[0013] As a further improvement of the present invention, the top surface level of the bent portion at the top of the first side panel is higher than the top surface level of the first supporting plate so that a first step portion is formed between the bent portion and the first supporting plate, so that the top surface of the installed transparent plate and the top surface of the bent portion at the top of the first side panel are on the same horizontal plane.

[0014] As a further improvement of the present invention, a first limiting reinforcement rib protruding into the light strip mounting groove is provided on the bottom surface of the first supporting plate to support the first supporting plate, and a first limiting space is formed between the first limiting reinforcement rib and the first side plate to allow the profile connector to be inserted into the first limiting groove and the first limiting space at the same time and then clamped and limited.

[0015] As a further improvement of the present invention, a back plate mounting plate protruding outward is provided on the other side of the second profile relative to the sliding limit mechanism, so as to support and fix the back plate of the road traffic sign.

[0016] As a further improvement of the present invention, a limiting slide rail for fixing the road traffic sign is provided at the bottom of the second profile, and a second limiting space is formed between the limiting slide rail and the back plate mounting plate for inserting the back plate of the road traffic sign.

[0017] As a further improvement of the present invention, a light source board mounting plate protruding outward is further provided on the second profile above the back plate mounting plate for supporting and fixing the internal light source board of the road traffic sign.

[0018] As a further improvement of the present invention, a second limiting reinforcement rib protruding toward the light source board mounting plate is also provided on the top surface of the back panel mounting plate to support the back panel mounting plate, and a third limiting space is formed between the second limiting reinforcement rib and the light source board mounting plate to clamp and limit the internal light source board after insertion.

[0019] As a further improvement of the present invention, a third supporting plate protruding outward is provided on the second profile above the light source board mounting plate for supporting a panel for fixing road traffic signs, and a second step portion is provided on the third supporting plate for making the top surface of the installed panel and the top surface of the second profile be on the same horizontal plane.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] First, the frame profile of the present invention is divided into two parts, which can be flexibly combined and split according to actual needs. It completely subverts the three-hole design of the prior art of sequentially arranging the first closed hole, the second closed hole and the U-shaped installation groove, and can be flexibly combined and split according to actual needs. It can meet the production requirements of road traffic signs that need to light up the edge graphics and text parts, and can also meet the production requirements of road traffic signs that do not need to light up the edge graphics and text parts, and has strong adaptability.

[0022] Secondly, the frame profile of the present invention, through its combination function, makes it possible to quickly assemble to meet the requirements when it is necessary to change an ordinary traffic sign into a traffic sign with illuminated edge graphics and text, without abolishing the original ordinary sign. This makes full use of existing resources and greatly reduces resource waste. In addition, the time for re-production is short, the labor intensity is low, the work efficiency is high, and the change can be achieved quickly and well.

[0023] Third, the frame profile of the present invention is specially designed so that the plug-in, pull-out, clamping and limiting method is very firm, and the operation is convenient and quick, which can well meet the requirements of combined use.

[0024] Fourth, the frame profile of the present invention completely overturns the existing situation that the lifting workpiece cannot be adjusted and moved by setting the second limiting groove. The lifting screw can slide flexibly in the second limiting groove. When it needs to be fixed, just tighten the lifting ring. When it needs to be adjusted, loosen the lifting ring and slide the lifting screw. The operation is convenient, easy and fast, which can well meet the needs of different lifting operations and greatly reduce the operation risk.

[0025] Fifth, the frame profile of the present invention completely overturns the design of the prior art of inserting a flange into a closed through hole. Instead, through the special scientific design of the second limiting groove, the profile connector is inserted to form a limit, and the connection is firm and stable with high safety. And most importantly, the profile connector can be exposed from the opening of the second limiting groove. This allows the connection degree or damage degree of the two to be observed at any time, and remedial measures can be taken in time; second, it allows the second limiting groove and the inserted profile connector to be welded, with a large welding area and fast welding operation (no need to rotate the profile), which further makes the connection firm and stable with high safety. The practice of punching is completely eliminated, making the installation efficient and the work easier and faster. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 7 As shown, the present invention provides a combinable frame profile for road traffic signs, including a first profile 1 and a second profile 2 that match each other, and the length of the first profile 1 and the second profile 2 ranges from 0.2 meters to 50 meters. The first profile 1 is provided with a light bar installation groove 14 with an upper end opening, which is used to install the light bar to light up the edge graphic part of the road traffic sign. The first profile 1 and the second profile 2 are detachably assembled and connected through a sliding limit mechanism 3, so that when assembled together, they can be used to make a road traffic sign with a graphic part on the edge that needs to be lit up / or when not assembled, only the second profile 2 is used to make a road traffic sign without a graphic part on the edge that needs to be lit up.

[0037] That is, the frame profile of the present invention is divided into two major parts, which can be flexibly combined and split according to actual needs. For example: when it is necessary to make a road traffic sign with an edge graphic part that needs to be illuminated, the first profile 1 and the second profile 2 can be assembled together to form a whole using the sliding limit mechanism 3 to make the frame of the sign, and the light bar mounting groove 14 on the first profile 1 can be used to install the light bar and then light up the edge graphic part of the road traffic sign, which meets the requirements well. Another example: when it is necessary to make an ordinary road traffic sign that does not need to light up the edge graphic part, the first profile 1 and the second profile 2 can be separated using the sliding limit mechanism 3, and then the second profile 2 can be used alone to make a road traffic sign that does not need to light up the edge graphic part, which can also meet the requirements well. Another example: when an ordinary road traffic sign made of the second profile 2 of the present invention needs to be changed into a light-emitting sign capable of lighting up the edge text and graphics of the road traffic sign, there is no need to discard the original sign, but the first profile 1 and the second profile 2 are assembled together by the sliding limit mechanism 3 to form a whole so that the function of lighting up the edge text and graphics is achieved. Then, only the corresponding modification needs to be made to the sign panel to add the edge text and graphics that need to be lit up. The above special scientific design has the following technical advantages:

[0038] First, the frame profile of the present invention completely overturns the prior art design of three holes, namely, the first closed hole, the second closed hole and the U-shaped mounting groove, which are arranged in parallel in sequence. Instead, it can realize flexible combination and splitting according to actual needs. It can meet the production requirements of road traffic signs that need to light up the edge graphics and text parts, and can meet the production requirements of road traffic signs that do not need to light up the edge graphics and text parts, and has strong adaptability.

[0039] Secondly, the frame profile of the present invention, through its combination function, makes it possible to quickly assemble to meet the requirements when it is necessary to change an ordinary traffic sign into a traffic sign with illuminated edge graphics and text, without abolishing the original ordinary sign. This makes full use of existing resources and greatly reduces resource waste. In addition, the time for re-production is short, the labor intensity is low, the work efficiency is high, and the change can be achieved quickly and well.

[0040] Furthermore, in a preferred embodiment, the sliding limit mechanism 3 includes a second limit groove 31 axially provided on the side wall of the second profile 2, and the sliding limit mechanism 3 also includes a T-shaped limit strip 32 axially protruding on the side wall of the first profile 1, and the second limit groove 31 is used to allow the T-shaped limit strip 32 to be inserted and clamped in the second limit groove 31 to allow the first profile 1 and the second profile 2 to be assembled and connected, or to allow the road traffic sign hoisting workpiece to be adjustable and limited and slid in the second limit groove 31 when not assembled, so as to facilitate the road traffic sign hoisting operation. That is, the sliding limit mechanism 3 is composed of the first profile 1 and the second profile 2, which are special and can cooperate with each other. This special structure has the following advantages:

[0041] First, the plug-in and pull-out clamping limit mode is very firm, and the operation is convenient and quick, which can well meet the requirements of combined use. Second, by setting the second limit groove 31, the existing situation that the hoisting workpiece cannot be adjusted and moved is completely overturned. The hoisting screw can flexibly slide in the second limit groove 31 (such as Figure 6 As shown, A is a lifting screw and B is a lifting ring). When it needs to be fixed, just tighten the lifting ring. When it needs to be adjusted, loosen the lifting ring and then slide the lifting screw. It is easy, easy and fast to operate, and can well meet the needs of different lifting operations, and the operation risk is greatly reduced. Third, it completely subverts the design of the flange inserted into the closed through hole in the prior art. Instead, through the special scientific design of the second limiting groove 31, the profile connector is inserted to form a limit, and the connection is firm and stable with high safety. And the most important thing is that the profile connector can be exposed from the opening of the second limiting groove 31. This makes it possible to observe the connection degree or damage degree of the two at any time, and take remedial measures in time; second, it makes it possible to weld the second limiting groove 31 and the inserted profile connector, with a large welding area and fast welding operation (no need to rotate the profile), which further makes the connection firm and stable with high safety. The practice of punching is completely eliminated, which makes the installation efficient and the work easier and faster.

[0042] Further, in a preferred embodiment, the first profile 1 includes a bottom plate 11, and the bottom plate 11 is provided with a first side plate 12 and a second side plate 13 facing upward on both sides along the axial direction, and the bottom plate 11, the first side plate 12 and the second side plate 13 are enclosed to form a light bar installation groove 14, and the outer surface of the first side plate 12 is provided with two upper and lower oppositely arranged bending parts 121, so as to form a first limiting groove 122 opened along the axial direction on the outer surface of the first side plate 12, and the first limiting groove 122 is used to make the road traffic sign hoisting workpiece movably limited and slidable in the first limiting groove 122 when the first profile 1 and the second profile 2 are assembled and connected, so as to facilitate the road traffic sign hoisting operation. This makes it possible to well meet the above-mentioned many technical advantages brought by the limiting grooves, whether the second profile 2 is used alone or the first profile 1 and the second profile 2 are used in combination.

[0043] Furthermore, in a preferred embodiment, a first supporting plate 123 is provided at the top of the first side plate 12, and a second supporting plate 131 is provided at the top of the second side plate 13 for supporting a transparent plate for fixing road traffic signs (as shown in C in the figure). The spacing between the first supporting plate 123 and the second supporting plate 131 is smaller than the inner diameter width of the bottom surface of the light bar mounting groove 14. Two parallel light bar limiting ribs 141 arranged along the axial direction are provided on the bottom surface of the light bar mounting groove 14 corresponding to the spacing between the first supporting plate 123 and the second supporting plate 131, so as to insert the light bar (as shown in D in the figure) between the two light bar limiting ribs 141 and then limit and install it in the light bar mounting groove 14.

[0044] The first bearing plate 123 and the second bearing plate 131 can provide good support for the transparent plate. At the same time, due to the need to set the first bearing plate 123 and the second bearing plate 131, the bottom inner diameter of the light bar installation groove 14 must have a certain width, and through the design of the two light bar limiting ribs 141, the width of the light bar is equal to the spacing between the first bearing plate 123 and the second bearing plate 131, without the need to make the width of the light bar equal to the bottom inner diameter of the light bar installation groove 14, which greatly reduces the width of the light bar and greatly reduces the manufacturing cost. At the same time, the design of the two light bar limiting ribs 141 not only makes it convenient and quick to pull out or insert the light bar, but also can form a good limit for the light bar. No matter how it is transported and hoisted, it will not be displaced, effectively ensuring the light indication effect.

[0045] Furthermore, in a preferred embodiment, the top surface level of the bent portion 121 at the top of the first side plate 12 is higher than the top surface level of the first carrier plate 123, so that a first step portion 124 is formed between the bent portion 121 and the first carrier plate 123, so that the top surface of the installed transparent plate is at the same level as the top surface of the bent portion 121 at the top of the first side plate 12. This facilitates the pasting of the reflective film, making the product smooth and beautiful as a whole.

[0046] Further, in a preferred embodiment, a first limiting reinforcing rib 125 protruding toward the light bar installation groove 14 is provided on the bottom surface of the first bearing plate 123 to support the first bearing plate 123, and a first limiting space 16 is formed between the first limiting reinforcing rib 125 and the first side plate 12, so that the profile connector is inserted into the first limiting groove 122 and the first limiting space 16 at the same time and then clamped and limited. Since the first bearing plate 123 needs to support the transparent plate, the first limiting reinforcing rib 125 is designed to support the first bearing plate 123, so that the product structure is stable. Second, a first limiting space 16 is formed between the first limiting reinforcement rib 125 and the first side plate 12. For example, a profile connector as shown in the figure can be adopted. When an upper part of the profile connector (as shown in G in the figure) is inserted into the first limiting groove 122, another lower part of the profile connector (as shown in H in the figure) can be inserted into the first limiting space 16 at the same time. This upper and lower clamp-shaped design allows the two to be firmly clamped and limited, and further allows the profile connector and the frame profile to support and limit each other, with a larger contact area and a more stable and reliable connection.

[0047] Furthermore, in a preferred embodiment, a back plate mounting plate 21 protruding outward is provided on the other side of the second profile 2 relative to the sliding limit mechanism 3 to support the back plate of the fixed road traffic sign (as shown in E in the figure).

[0048] Furthermore, in a preferred embodiment, a limiting slide rail 4 for fixing the road traffic sign is provided at the bottom of the second profile 2, and a second limiting space 24 is formed between the limiting slide rail 4 and the back plate mounting plate 21 for inserting the back plate of the road traffic sign. Since there may be cutting errors when the back plate is manufactured, the size of the back plate may not be completely accurate, especially when making large-area signs (such as several square meters or even more than ten square meters), errors are inevitable. For this reason, by providing a second limiting space 24 in the shape of a groove, if the actual size of the back plate is larger than the required size, the back plate can be moved into the second limiting space 24 for position adjustment, which further improves the convenience of installation and maintenance.

[0049] Furthermore, in a preferred embodiment, a light source board mounting plate 22 protruding outward is provided on the second profile 2 above the back plate mounting plate 21 to carry and fix the internal light source board of the road traffic sign (as shown in F in the figure). This allows the second profile 2 to have multiple functions, and can cooperate with other components in the sign to fix the internal light source board, and also makes the internal light source board more firmly and stably arranged.

[0050] Furthermore, in a preferred embodiment, a second limiting reinforcement rib 211 is provided on the top surface of the back panel mounting plate 21 and protrudes toward the light source board mounting plate 22 to support the back panel mounting plate 21. A third limiting space 5 is formed between the second limiting reinforcement rib 211 and the light source board mounting plate 22 to clamp and limit the internal light source board after insertion, so that one side of the internal light source board can be fixed without additional fixing parts, thereby reducing the weight of the sign and reducing the production cost.

[0051] Furthermore, in a preferred embodiment, a third bearing plate 23 protruding outward is provided on the second profile 2 above the light source board mounting plate 22 for bearing a panel for fixing a road traffic sign (as shown by K in the figure), and a second step portion 231 is provided on the third bearing plate 23 for making the top surface of the installed panel and the top surface of the second profile 2 be at the same level. This design enables the second profile 2 to provide good support for the panel when used alone, and makes the installation beautiful and smooth.

Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
