Description

Technical Field

[0001] This utility model relates to the technical field of signs for safe construction on highways. Background Technology

[0002] During road construction, warning zones, upstream transition zones, and buffer zones should be set up, with a total length of not less than 1.5 km. Within these zones, signs such as "Construction Ahead," "No Overtaking," "Lane Narrowing Ahead," "No Entry," "Guide," and "Speed ​​Limit" should be uniformly set up.

[0003] Existing signs are generally made of aluminum alloy, which is lightweight. Based on the fixing method, existing signs are divided into fixed and mobile types. Fixed signs are generally fixed to a gantry frame or to a column or pole, and the fixing method is generally steel hoops, that is, the sign is directly fixed with steel hoops.

[0004] The problems with using steel hoops to fix signs are: there are gaps between the steel hoops and the gantry and columns, and the bolts that fasten the steel hoops are prone to loosening, especially under wind pressure, which can cause the signs to shift or become displaced. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a road construction sign that solves the problems of unreliable fixation and cumbersome disassembly and assembly of temporary signs during existing road construction.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] A road construction sign includes a sign body, a straight rod, and a fixing part. The fixing part comprises a fastener and a locking component. The fastener consists of a stainless steel plate and symmetrically arranged side wings on both sides of the stainless steel plate. The locking component includes a pull rod, a compression spring, a handle, and a support rod. The pull rod passes vertically through a hole in the stainless steel plate. An elongated hole I is provided at the lower end of the pull rod, and this hole I is movably engaged with an elongated hole II via a steel pin. The elongated hole II is located on the support rod, which has rotational space relative to the pull rod and sliding space relative to the pull rod along its length. The pull rod has a protrusion in the middle, and a compression spring is sleeved on the pull rod between the protrusion and the stainless steel plate. A handle is hinged to the upper end of the pull rod. The hinge point between the handle and the pull rod is eccentric; rotating the handle causes the pull rod to move axially.

[0008] Furthermore, the stainless steel plate has a hexagonal structure with the same outline as the anti-blocking block in its top view, and the side wings are vertically fixed to the edge of the stainless steel plate.

[0009] Furthermore, at least one of the six sides of the stainless steel plate is a curved edge.

[0010] Furthermore, each wing is a prismatic structure composed of two small plates, which is inserted into the inner corner edge of the anti-blocking block cavity.

[0011] Furthermore, a slot is provided on the support rod to engage with the lower edge of the anti-blocking block.

[0012] The beneficial effects of this utility model are:

[0013] The sign can be installed or removed with a single button press using the control handle, making it very convenient and efficient.

[0014] The locking element secures the fixing part and the anti-blocking block through axial tension, and the prism-fitting structure between the anti-blocking block and the fastener effectively solves the problem of sign rotation. Attached Figure Description

[0026] 30 anti-blocking blocks. Detailed Implementation

[0027] Road construction signs are used in road construction. They are designed with the characteristics of road construction in mind, featuring rapid deployment and installation, rapid dismantling and relocation, and reliable installation.

[0028] Considering the characteristics of highways, especially the widely used corrugated guardrail structure, which is included in GB / T 31439.1-2015, the standard for corrugated beam steel guardrails, this embodiment addresses the issue. Specifically, the anti-blocking blocks, typically employing a hexagonal hollow prism structure, are securely connected to the posts and corrugated guardrail panels using bolts. In other words, anti-blocking blocks are ubiquitous. Furthermore, the anti-blocking blocks have a vertically continuous structure. This embodiment, based on the characteristics of anti-blocking blocks, presents a sign and its installation structure specifically designed for the installation of anti-blocking blocks at specific locations.

[0029] refer to Figures 1 to 3 The upper part of the road construction sign is the sign body 00, on which slogans are printed or affixed, such as "Construction Ahead," "No Overtaking," "Lane Narrowing Ahead," "No Entry," "Guide," and "Speed ​​Limit," etc. The middle section is an aluminum alloy straight rod 01. The lower end is the fixing part, specifically referring to the part that allows for quick and reliable connection with the aforementioned anti-blocking block.

[0030] The fixing part includes a fastener 10 and a locking member 20. The fastener consists of a hexagonal stainless steel plate 11 and symmetrically arranged side wings 12 on both sides of the stainless steel plate. Specifically, the hexagonal stainless steel plate has a structure that matches and is slightly larger than the anti-blocking block in its top view, meaning that the stainless steel plate 11 can completely cover and slightly overlap the upper opening of the anti-blocking block. The side wings are welded to both sides of the stainless steel plate. In a specific and effective form, each side wing is composed of two small plates, which are vertically fixed to the edge of the stainless steel plate. The two small plates form a prismatic structure, which is inserted into the inner corner edge of the anti-blocking block's inner cavity. That is, the fastener can be quickly inserted into the anti-blocking block from top to bottom. The dimension of the side wing in the height direction should not be too large, and it is preferable not to contact the connecting bolts.

[0031] Among the fasteners mentioned above, similar to the outline of the anti-blocking block, one of the six edges is an arc-shaped edge 13, which matches the outer outline of the aforementioned column. The anti-blocking block also has one arc-shaped surface.

[0032] On the aforementioned stainless steel plate 11, at non-central positions, there is an aluminum alloy straight rod fixing point and a locking component mounting point. The aluminum alloy straight rod mounting point is used to fix the aforementioned aluminum alloy straight rod, and the fixing method can be welding, threading, riveting, etc.

[0033] The aforementioned locking component mounting points are used to install locking components.

[0034] The locking component 20 consists of a pull rod 21, a compression spring 22, a handle 23, and a support rod 24. The pull rod 21 passes vertically through a circular hole in the stainless steel plate, avoiding the connecting bolts. The lower end of the pull rod has an elongated hole I, which engages with an elongated hole II via a steel pin 25. Elongated hole II is an effective feature on the support rod, allowing for a wide range of rotation and sliding relative to the pull rod along its length, as well as providing space. This sliding capability effectively adjusts the fit between the support rod and the lower edge of the anti-blocking block.

[0035] Furthermore, the support rod 24 is provided with a small-sized slot that engages with the lower edge of the anti-blocking block. There are multiple slots, which can effectively prevent the relative sliding of the support rod.

[0036] The pull rod 21 has a protrusion in the middle, which also serves as a limiting part for the compression spring. The compression spring is restricted in the axial direction by the protrusion and the lower surface of the stainless steel plate.

[0037] A handle 23 is movably connected to the upper end of the pull rod via a round pin. The hinge connection point between the handle and the pull rod is an eccentric structure 231. Specifically, when the handle is rotated, it rotates along the hinge point. During the rotation, the eccentric structure causes the pull rod to move axially. Specifically, the movement is divided into upward movement and downward movement of the pull rod, which are achieved by the forward and reverse rotation of the handle.

[0038] The installation method is as follows:

[0039] refer to Figures 4 to 6 First, fasten the fastener onto the open position of the aforementioned anti-blocking block 30 (the size conforms to national standards). Then, with the support rod and pull rod in the closed state, pass them through the inner cavity of the anti-blocking block. After passing through, use your hand to pry out the support rod at the lower open position of the anti-blocking block and place it in a horizontal position, so that the slot on the support rod is locked into the lower edge of the anti-blocking block. Then, turn the handle. Under the action of the eccentric structure, the pull rod moves upward, compresses the compression spring, and securely fixes the support rod to the anti-blocking block, thereby achieving quick fixation.

[0040] Once fixed, the sign is securely attached to the anti-blocking block by the fixing part. There are a large number of anti-blocking blocks, which can be quickly fixed according to the appropriate position.

[0041] The disassembly method is as follows:

[0042] refer to Figures 4 to 6First, turn the handle in the opposite direction. Under the action of the eccentric structure and the restoring force of the compression spring, the pull rod moves down, which loosens the support rod and the anti-blocking block. After loosening, use your hand to help rotate and slide the support rod and tilt it to close it with the pull rod, so that the mounting part and the anti-blocking block can be separated as a whole.

[0043] As can be seen from the above process, the sign can be disassembled and assembled with a single button operation using the handle, which is very convenient and efficient.

[0044] Furthermore, the locking element secures the fixing part and the anti-blocking block through axial tension, and the prism-fitting structure between the anti-blocking block and the fastener effectively solves the problem of sign rotation.

[0045] This technology enables efficient fixing of signs.

[0046] This embodiment and accompanying drawings are merely descriptions of preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements to the present utility model by those skilled in the art should fall within the protection scope defined by the claims of the present utility model.
