Abstract

The utility model provides an advertisement brand support, which comprises a horizontally-arranged upper support bar (5), a horizontally-arranged lower support bar (7), a rear vertical post for connecting the upper support bar (5) and the lower support bar (7), and a base (8) extended backwards along the joint of the rear vertical post and the lower support bar (7). The utility model is characterized in that a length- adjusting apparatus is arranged on the rear vertical post. The utility model has the advantages of adjustment of the distance between the upper support bar and the lower support bar due to the adjustable length of the rear vertical post, practicability in advertisement brands of different length, and wide application.

Description

Bill-board support

Technical field

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

Background technology

In the prior art, the base that bill-board support comprises horizontally disposed upper support bar, horizontally disposed lower support bar, is used to connect the rear column of described upper support bar and lower support bar, extend back along the junction of described rear column and lower support bar is supported entire bracket jointly by base and lower support bar.Be connected with the bottom and upper segment of billboard on upper support bar and the lower support bar respectively, rear column is the rod member that length can not be regulated, it is bent to arc in use, make that billboard is able to be opened, the rear column of this structure can not be applicable to the opening of billboard of different length, and therefore existing bill-board support uses inconvenient.，

Summary of the invention

The purpose of this utility model is to provide a kind of bill-board support that can support the billboard of different length.

The technical solution of the utility model is: a kind of bill-board support, comprise horizontally disposed upper support bar, horizontally disposed lower support bar, be used to connect the rear column of described upper support bar and lower support bar, that backward or the base that extends forward described rear column is provided with length adjustment mechanism along the junction of described rear column and lower support bar.

The utility model compared with prior art has following advantage:

Because the length of rear column can be regulated, so the distance between upper support bar and the lower support bar regulated, and is used to open the billboard of different length, and applicable surface is more extensive.

Description of drawings

Accompanying drawing 1 is a spatial structure view of the present utility model;

Accompanying drawing 2 is a kind of structure cut-open view of rear column;

Accompanying drawing 3 is the another kind of structure cut-open view of rear column; Wherein:

[11] outer loop bar; [2], keeper; [3], bolt; [4], upper pillar stand; [5], upper support bar; [6], billboard; [7], lower support bar; [8], base; [9], interpolation pole cover; [10], interpolation pole; [11], elastic threads; [12], elastic threads cavity; [13], overcoat bar jack; [14], inserting column; [15], spring;

Embodiment

Referring to accompanying drawing 1, a kind of bill-board support, comprise horizontally disposed upper support bar [5], horizontally disposed lower support bar [7], be used to connect the rear column of described upper support bar [5] and lower support bar [7], the base [8] that extends back along the junction of described rear column and lower support bar [7], described rear column is provided with length adjustment mechanism.Described length adjustment mechanism comprises outer loop bar [1], be inserted in interpolation pole [10] in the inner chamber of described outer loop bar [1], be used to lock the locking mechanism of the relative position of described outer loop bar [1] and interpolation pole [10].Referring to accompanying drawing 2, described locking mechanism comprises the bolt [3] that interpolation pole [10] is gone up the keeper [2] of cover, passed keeper [2] and be threaded with it; When tighting a bolt [3], described locking mechanism is under the locking state, and the end of described screw rod withstands on the interpolation pole [10], and then keeper [2] is fixed on the interpolation pole [10].

The upper end of described interpolation pole [10] is fixed with the interpolation pole cover [9] that radially becomes big, and described keeper [2] is positioned at the below of described interpolation pole cover [9].Also be inserted with upper pillar stand [4] on the described interpolation pole cover [9], upper pillar stand [4] can be extracted from interpolation pole cover [9], is convenient to the folding usefulness of rear column.The elastic threads cavity [12] that is axially arranged with perforation of described upper pillar stand [4] and interpolation pole [10], be provided with elastic threads [11] in this elastic threads cavity [12], the two ends of described elastic threads [11] are fixedly attached to respectively on upper pillar stand [4] and the outer loop bar [9], and the upper end of then outer loop bar [1] is pressed on the keeper [2] all the time.And keeper [2] is fixed on the diverse location of interpolation pole [10], can so that the length of the part rear column that is constituted of overcoat bar [1] and interpolation pole [10] regulated.

Referring to accompanying drawing 3, described another kind of locking mechanism comprises the inserting column [14] that interpolation pole [10] upward slides and is provided with, be provided with spring [15] between the inwall of described inserting column [14] and interpolation pole [10], described outer loop bar [1] upper edge short transverse has a plurality of overcoat bar jacks [13], and described inserting column [14] is inserted in the described overcoat bar jack [13].After pressing inserting column [14], can slide relatively between interpolation pole [10] and the outer loop bar [1], then after highly regulating, can select the outer tube jack [13] on the outer loop bar [1], make inserting column [14] be inserted in the corresponding overcoat bar jack [13].

Claims

1, a kind of bill-board support, comprise horizontally disposed upper support bar [5], horizontally disposed lower support bar [7], be used to connect the rear column of described upper support bar [5] and lower support bar [7], that backward or the base [8] that extends forward it is characterized in that: described rear column is provided with length adjustment mechanism along the junction of described rear column and lower support bar [7].

2, bill-board support according to claim 1 is characterized in that: described length adjustment mechanism comprises outer loop bar [1], be inserted in interpolation pole [10] in the inner chamber of described outer loop bar [1], be used to lock the locking mechanism of the relative position of described outer loop bar [1] and interpolation pole [10].
