Abstract
Description
Technical Field
[0001] This utility model relates to the field of road sign technology, specifically to a temporary road sign. Background Technology
[0002] Temporary road signs are mainly used at construction sites, temporary parking lots, markets, open-air concerts, exhibitions, and other venues. Existing temporary road signs have the following drawbacks: 1. They often use simple fixing methods, such as directly inserting them into the ground or supporting them with simple brackets. These are prone to swaying, tilting, or even toppling when exposed to strong winds, vehicle collisions, or other external forces. 2. Some existing temporary road signs have complex structures, requiring specialized tools and considerable time for installation and dismantling. Others are difficult to disassemble due to easily damaged connecting parts. 3. Road signs that are not securely fixed or have loose connections are prone to rotation or displacement, leading to incorrect directional indication. Utility Model Content
[0003] To overcome the above-mentioned shortcomings in the prior art, this utility model provides a temporary road sign with a stable structure and convenient direction adjustment.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] A temporary road sign includes a post and several road signs, each road sign having a connecting sleeve at one end. The connecting sleeves of the road signs are stacked and fitted onto the post.
[0006] A first retaining ring and a second retaining ring are provided. The first retaining ring is pinned to the column to support each of the connecting sleeves. The second retaining ring is threaded to the top of the column to hold each of the connecting sleeves. Each of the connecting sleeves and the first retaining ring are provided with a mutually cooperating locking mechanism.
[0007] Preferably, the column is provided with several pin holes, so that the pin connection position of the first retaining ring is adjustable.
[0008] In any of the above embodiments, it is preferred that the lower part of the first retaining ring is provided with a groove for receiving the end of the pin of the first retaining ring to be engaged with the retaining pin.
[0009] In any of the above embodiments, it is preferred that a rain cover is provided on the outer wall of each connecting sleeve near the bottom and on the outer wall of the second retaining ring near the bottom, and each rain cover extends downward to at least the bottom of the connecting sleeve and the second retaining ring.
[0010] In any of the above embodiments, a preferred embodiment is that a sliding sleeve is slidably connected to the outer wall of the second retaining ring, the bottom of the sliding sleeve is in contact with the connecting sleeve, and a spring is provided between the upper part of the sliding sleeve and the second retaining ring.
[0011] In any of the above solutions, it is preferred that the structure of the locking mechanism is a locking tooth or a locking groove and a locking block that cooperate with each other.
[0012] Preferably, in any of the above solutions, the body of each road sign and the connecting sleeve are provided with tie rods.
[0013] In any of the above embodiments, it is preferred that the bottom of the column is provided with rollers.
[0014] In any of the above solutions, it is preferred that the roller is a fusible wheel or a swivel caster.
[0015] This utility model discloses a temporary road sign, comprising a post and several road signs. Each road sign has a connecting sleeve at one end. The connecting sleeves of the road signs are stacked and fitted onto the post. A first retaining ring and a second retaining ring prevent axial movement between the connecting sleeves and the post. Under the constraint of the locking mechanism between the connecting sleeves and between the first retaining ring and the connecting sleeves, relative rotation between the road signs and the post is prevented. Therefore, it has the beneficial effect of structural stability.
[0016] When adjusting the direction of the road signs, the connecting sleeves can be moved axially along the column by loosening the second retaining ring, which can free them from the constraints of the locking mechanisms and thus adjust the direction of each road sign. Therefore, it has the beneficial effect of convenient direction adjustment. Attached Figure Description

[0030] Example 1:
[0031] like Figure 1 , 4 In the illustrated embodiment, the column 103 serves to install various functional components. The column 103 can be made of stainless steel pipe, iron pipe, aluminum alloy pipe, or other profiles. When iron pipe is used, to prevent corrosion of the surface of the column 103, the outer wall can be treated with galvanizing, painting, or other anti-corrosion methods. In use, one optional form of connection between the column 103 and the ground is that a mounting plate is installed at the bottom of the column 103, and the mounting plate is fixed to the ground with anchor bolts. Another optional form of connection between the column 103 and the ground is that the bottom of the column 103 is equipped with rollers 104, which facilitate the movement of the temporary road sign. To prevent errors in the directional indication of the road sign 102 due to changes in the relative position between the column 103 and the ground, the rollers 104 are either casters with braking functions or swivel casters.
[0032] One end of each road sign 102 is connected to the outer wall of the connecting sleeve 106 by welding or snap-fit. Each road sign 102 is fitted onto the post 103 via the connecting sleeve 106.
[0033] The first retaining ring 105 is fixedly connected to the column 103 via a pin connection, and serves to support the stacked connecting sleeves 106. The second retaining ring 101 is threaded onto the top of the column 103, and serves to hold the connecting sleeves 106 in place. The action of the first and second retaining rings 105 and 101 prevents the connecting sleeves 106 from axially moving relative to the column 103.
[0034] Each connecting sleeve 106 and each connecting sleeve 105 is provided with a cooperating locking mechanism. One optional form of each locking mechanism is a cooperating locking tooth. Another optional form is a cooperating locking groove and a locking block. These locking mechanisms prevent relative rotation between the connecting sleeve 106 and the column 103.
[0035] In use, first fix the position of the post 103 to the ground, then pin the first retaining ring 105 to the post 103. According to the location of each target object, place the connecting sleeve 106 of each road sign 102 on top of the first retaining ring 105 and secure it using the locking mechanism. Finally, connect the second retaining ring 101 to the top of the post 103, so that the bottom of the second retaining ring 101 abuts against the stacked connecting sleeves 106.
[0036] Example 2:
[0037] Based on Example 1, such as Figure 4In the embodiment shown, in order to make the number of road signs 102 placed at the post 103 adjustable, a number of pin holes are provided at the post 103. The position of each pin hole should be set to ensure that when the first retaining ring 105 is connected to each pin hole, the distance between the upper part of the first retaining ring 105 and the lower part of the second retaining ring 101 is an integer multiple of the height of a single connecting sleeve 106. In specific use, the relative position of the connection between the first retaining ring 105 and the post 103 is adjusted according to the number of connecting sleeves 106.
[0038] Example 3:
[0039] Based on Example 1 or 2, such as Figure 4 In the illustrated embodiment, to facilitate the quick connection between the first retaining ring 105 and each pin hole, a groove 109 is provided at the lower part of the first retaining ring 105 to hold the end of the pin that is pinned to the first retaining ring 105. When the first retaining ring 105 and the pin hole are pinned together, the pin is inserted into the corresponding pin hole. Since it is not necessary to align the pin hole at the first retaining ring 105 with the pin hole at the column 103, the insertion of the pin becomes easier. After the pin is inserted into the pin hole at the column 103, the first retaining ring 105 is moved down, so that both ends of the pin are engaged in the groove 109 at the bottom of the first retaining ring 105. At the same time, under the constraint of the groove 109, the pin is also prevented from moving radially along the column 103.
[0040] Example 4:
[0041] Based on any of the embodiments 1-3, such as Figure 6 , 7 In the illustrated embodiment, to prevent rainwater from seeping in through the gaps between the second retaining ring 101 and the connecting sleeve 106, the gaps between adjacent connecting sleeves 106, and the gap between the first retaining ring 105 and the connecting sleeve 106 during outdoor use, thus preventing rust, a rain cover 111 is provided on the outer wall of each connecting sleeve 106 near the bottom and on the outer wall of the second retaining ring 101 near the bottom. Each rain cover 111 extends downwards at least to the bottom of the connecting sleeve 106 and the second retaining ring 101. The rain cover 111 can be connected to the outer wall of the second retaining ring 101 near the bottom and the outer wall of the connecting sleeve 106 near the bottom by bonding or welding.
[0042] Example 5:
[0043] Based on any of the embodiments 1-3, such as Figure 2 , 3In the illustrated embodiment, when the temporary road sign is applied to construction sites, exhibitions, or other scenarios, and the location of the sign is adjusted (e.g., changes in the location of construction materials or the layout of the exhibition area) or the placement of the temporary road sign changes, a sliding sleeve 107 is slidably connected to the outer wall of the second retaining ring 101 in order to quickly adjust the road sign 102. The bottom of the sliding sleeve 107 contacts the connecting sleeve 106. The two ends of the spring 108, which is located between the upper part of the sliding sleeve 107 and the second retaining ring 101, are fixedly connected to the upper part of the sliding sleeve 107 and the second retaining ring 101, respectively.
[0044] In use, under the action of the spring 108, the sliding sleeve 107 presses against the connecting sleeve 106 of each road sign 102, thereby preventing relative rotation between each road sign 102 and the column 103. When it is necessary to adjust the indicating direction of each road sign 102, simply push the sliding sleeve 107 upward, so that the connecting sleeve 106 of each road sign 102 can move along the axis of the column 103, thereby getting rid of the restraint of the locking mechanism between each connecting sleeve 106 and between the first retaining ring 105 and the connecting sleeve 106, so that the indicating direction of each road sign 102 can be adjusted.
[0045] Example 6:
[0046] Based on any of the embodiments 1-5, such as Figure 5 In the embodiment shown, in order to prevent stress concentration at the connection point between the body of each road sign 102 and the connecting sleeve 106, which could lead to breakage of the connection point, a tie rod 110 is provided between the body of each road sign 102 and the connecting sleeve 106.
[0047] The above-described embodiments are merely preferred embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be covered within the protection scope of this utility model.
