Abstract

A reflecting triangle sign consists of a triangle sign body and a support in the shape of “I”. The support comprises a center pole and four legs connected to two ends of the center pole pivotally, in which each leg is constructed from at least two short rods connected by a pivot, and at least one short rod is counterweight.

Description

TECHNICAL FIELD The present invention relates to a reflective triangular beacon, and particularly to a foldable reflective triangular beacon which has a stable setting position, is easy to manufacture and process, and has a good alert effect. BACKGROUND OF THE INVENTION In the prior art, there are roughly two types of reflective triangle beacons, as shown in Figure 1-3. One of the reflective triangular beacons shown in FIG. 1 is used to set up the bracket 2 of the triangular beacons 1 in a substantially "+" shape, which is formed by two flat irons 21 pivoted through a pivot 22 This kind of bracket 2 has a simple structure, but when the reflective triangle is tilted slightly by the wind, the phenomenon that a flat iron 21 rotates around the pivot axis 22 easily occurs, resulting in the unstable support of the bracket V and reflection. The triangular mark is dumped as a whole, and the effect of alertness cannot be achieved. In the other reflective triangular mark shown in Figs. 2 and 3, the bracket 2 used to set up the triangular mark body 1 is "roughly" shaped by a center. The rod 21 "and four circular supporting rods 22" movably connected to the ends of the center rod 21 ". This bracket 2 must be equipped with weights on the center rod 21" to increase the weight of the bracket 2 ". It can play a solid supporting role to prevent the reflective triangle from falling down in the wind as a whole. However, the addition of counterweights complicates the product structure and makes the manufacturing process cumbersome. Moreover, the contact surface of the circular support rod 22 "with the ground is small. , Low friction, wind The time pole slips with the wind and also affects the alert effect. SUMMARY OF THE INVENTION The main object of the present invention is to provide a reflective triangle with a stable setting position, easy manufacturing and processing, and good alert effect.

A secondary object of the present invention is to provide a reflective triangle which is convenient for folding and unfolding operations.

To achieve the above objective, the solution of the present invention is:

Reflective triangle mark, which is mainly composed of triangle mark body and bracket. The bracket is roughly "I" -shaped. The bracket consists of a central rod and four supporting rods which are pivotally connected at both ends of the central rod. Among them: the supporting rod consists of two sections. The above short rods are pivotally connected, and at least one short rod is a counterweight rod, such as a flat iron.

A flat non-slip foot pad is inserted at the end of the shortest pole of each of the above-mentioned rods. The bottom of the non-slip foot pad has a contact surface in contact with the plane to be erected. The contact surface is a rough surface. The frictional cooperation with the plane to be erected can further prevent the reflective triangle from sliding with the wind as a whole, and ensure the effect of alertness. The above-mentioned movable pivot is connected to two support rods at the same end of the center rod, and an intermeshing gear is formed at the pivot end. With the gear meshing, the two support rods can be interconnected, and the folding and unfolding operations of the bracket are more convenient. Convenience.

The short sections of the above-mentioned support rods are positioned during deployment by means of a positioning structure. For example: The two short sections that are pivotally connected to each other form a mating card seat and a convex block. The positioning and cooperation between the card seat and the convex block make the two short sections to be positioned when the pole is deployed.

After adopting the above structure, the present invention is compared with the prior art, because the bracket is designed in an "I" shape, and a support rod having at least one weight bar (such as a flat iron) is selected instead of a common circular support rod. The setting position of the frame is stable, so that the reflective triangle mark does not fall down when it is exposed to the wind, and the alert effect is good. At the same time, it is not necessary to add weights, and the manufacturing process is easy. If the shortest pole in the outermost section of the support rod is made of flat iron (especially after the addition of flat non-slip foot pads), the contact surface with the ground will increase, and the friction will also increase.

In addition, the present invention forms the mutually meshing gears of the pivotal ends of two adjacent struts. With this gear meshing, the synchronous folding and unfolding of the two struts can be realized, so that the folding and unfolding operations of the bracket are more For convenience.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 4, the reflective triangle mark disclosed in the present invention is mainly composed of a triangle mark body 1 and a bracket 2. The bracket 2 is generally in an “I” shape, and the bracket 2 includes a center rod 21 and a movable pivot The four supporting rods 22 connected to the two ends of the center rod 21 are the key of the present invention: the supporting rod 22 is pivotally connected by two or more short rods, and at least one of the short rods is a counterweight rod, such as a flat iron or other Rod with both counterweight.

The number of short shots can be determined by design. This article uses two sections (as shown in Figures 4 and 8) and three The section (shown in Figure 10) is used as an example.

There are many types of short joints. As shown in Fig. 4, the pivot joint between the two short levers is realized by a pivot base that can rotate with each other in the horizontal plane. As shown in Figs. As shown in FIG. 10 and FIG. 11, the pivot connection between the three short rods is realized by using a pivot base and a pivot shaft that can rotate with each other in the horizontal plane and the vertical plane at the same time.

It should be noted that: in order to make the bracket 2 more stable when deployed, the short sections of the support rod 22 can be positioned during deployment by means of a positioning structure. This positioning structure has many specific forms, for example, the support rod 22 is pivotally connected to each other. The two clips 25 and the projection 26 are formed between the two short rods. The positioning and cooperation between the clips 25 and the projection 26 make the two short rods positioned when the support rod is deployed, as shown in Figure 8, As shown in FIG. 10, this positioning structure is particularly suitable for pivotal positioning in a vertical plane, which allows the bracket 2 to be positioned when it is deployed. The positioning structure is a common structure in the prior art, and is not enumerated here.

In this way, the present invention follows the "I" design of the bracket 2 and replaces the ordinary circular supporting pestle 21 "with a supporting rod 22 having a section of weight bar. Therefore, the setting position of the frame is stable, so that the reflective triangle mark meets the whole The wind does not fall, and the alert effect is good. At the same time, since the weight of the weight greatly increases the weight of the bracket 2, there is no need to add weights, the structure is simple, and the manufacturing process is easy. If the outermost short rod of the rod 22 is short The flat iron is selected, because the contact surface between the flat iron and the ground is significantly increased, and the friction force is also increased. If the wind does not slip, the surveillance effect will be better.

The present invention further inserts a flat non-slip foot pad 23 at the end of the shortest outer part of each of the support rods 22, and as shown in FIGS. 5 and 6, the bottom of the non-slip foot pad 22 has a The contact surface where the planes are in contact. The contact surface is a rough surface. The frictional cooperation between the contact surface and the plane to be erected can further prevent the reflective triangle from sliding along with the wind to ensure the effect of alertness.

In order to facilitate the folding and unfolding of the bracket 2, as shown in FIG. 7, the present invention further pivotally connects the pivot ends of the two support rods 22 at the same end of the center rod 21 to form an intermeshing gear 24, with which the gear 24 meshes It can realize the simultaneous folding and unfolding of two adjacent supporting rods 22, so that the folding and unfolding operations of the bracket 2 are more convenient.
