Abstract
The utility model discloses a ladder paralleling pull rod. The ladder paralleling pull rod comprises two straight poles and connecting parts between the two straight poles and is characterized in that the connecting parts are 7-shaped; the flanges are arranged at one ends, connected with the straight poles, of the connecting parts; the two sides of each straight poles are coated with the flanges; the other ends of the connecting parts are connected mutually to form the pull rod. The ladder paralleling pull rod disclosed by the utility model has the advantages that the good paralleling and stabling effects of a ladder can be achieved, and the ladder paralleling pull rod is unlikely to bend.
Description
Technical field
The utility model relates to the accessory technical field of double ladder, especially a kind of parallel draw bar for both sides ladder.
Background technology
At present, connect on the market herringbone ladder both sides support bar, make ladder reach parallel pull bar, usually all by two straight-bars, by rivet is hinged, formed, and this connecting rod is in the process of using, do not reach good parallel and stablizing effect, under long use and stressing conditions, pull bar is easy to just bending, to people, brings inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of ladder parallel draw bar, makes ladder reach good parallel and stablizing effect, and is difficult for bending.
The utility model solves the technical scheme that its technical problem adopts: a kind of ladder parallel draw bar, comprise two straight-bars, and the connector between straight-bar and straight-bar, it is characterized in that: described connector is " ┐ " shape, one end that described connector is connected with straight-bar is provided with the flange of coated straight-bar both sides, and the other end of connector is interconnected to form pull bar.
Between described connector and straight-bar, by rivet, be connected.
Between described connector and straight-bar, by Type of Welding, be connected.
Hinged by rivet between described connector and connector.
Align near a side of flange with the connector other end in one end of described straight-bar.
The beneficial effects of the utility model are: a kind of ladder parallel draw bar, can prevent straight-bar flexural deformation when lengthening, and strengthened steadiness and the safety of ladder; One end that connector is connected with straight-bar is provided with the flange of coated straight-bar both sides, makes pull bar more stable, fastening; Aliging near a side of flange with the connector other end in one end of straight-bar, when making both sides straight-bar stretching, guarantees that straight-bar and straight-bar, on same straight line, increase steadiness.
Accompanying drawing explanation
Fig. 1 is the structural representation of ladder parallel draw bar.
Fig. 2 is the structural representation of connector in ladder parallel draw bar.
1. straight-bars in figure, 2. connector, 3. flange, 4. rivet.
The specific embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further described.Should be appreciated that embodiment described herein is only for explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of ladder parallel draw bar, comprises two straight-bars (1), and the connector between straight-bar and straight-bar (2), hinged by rivet (4) between connector and connector.
As shown in Figure 2, connector (2) is " ┌ " shape, one end that connector (2) is connected with straight-bar (1) is provided with the flange (3) of coated straight-bar (1) both sides, the other end of connector (2) is interconnected to form pull bar, aligns near a side of flange (3) with connector (2) other end in one end of straight-bar (1).
Between straight-bar (1) and connector (2), can pass through rivet (4) form hinged or direct welding connects.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, replace and improvement etc. on an equal basis, within all should dropping on protection domain of the present utility model.
