Abstract

The utility model provides a support frame of bill-board, includes the upper strut pole [2] that the level set up, the lower strut pole [4] that the level set up, rear column [11], the upper end of rear column [11] be connected with upper strut pole [2], the lower tip of rear column [11] be connected with the rear end of base [5], the preceding tip of base [5] be equipped with open mouthful socket [10], lower strut pole [4] insert in socket [10 ]. Because the open-ended socket sets up on the great base of volume, therefore this socket fixed connection is reliable on the base, and the socket can be through the form one shot forming of moulding plastics, can reduce its manufacturing cost.

Description

The bracing frame of billboard

Technical field

The utility model relates to a kind of support that billboard is used that supports.

Background technology

In the prior art, the bracing frame of billboard comprises horizontally disposed upper support bar, horizontally disposed lower support bar, rear column, the upper end of described rear column is connected with upper support bar, the bottom of described rear column is connected with the rearward end of base, the leading section of described base is connected with the lower support frame, its ways of connecting is the socket that the lower support frame is provided with U-shaped, and the leading section of base is inserted in this socket.This connected mode is because the socket of U-shaped is to be arranged on the shaft-like lower support bar, so the U-shaped socket is unreliable with being connected of lower support bar, and the U-shaped socket is easy to come off from lower support bar.And the U socket is arranged at the cost of manufacture that can cause lower support bar on the lower support bar and becomes big.

Summary of the invention

The purpose of this utility model is to provide the bracing frame that be connected reliable billboard of a kind of lower support bar with base.

The technical solution of the utility model is: a kind of bracing frame of billboard, comprise horizontally disposed upper support bar, horizontally disposed lower support bar, rear column, the upper end of described rear column is connected with upper support bar, the bottom of described rear column is connected with the rearward end of base, the leading section of described base is provided with the socket of dehiscing, and described lower support bar is inserted in the described socket.

The utility model compared with prior art has following advantage:

Because the socket of opening is arranged on the bigger base of volume, so this socket is fixedly connected reliable on base, and socket can reduce its production cost by the form one-shot forming of injection moulding.
