Abstract
A connection structure of a front ladder frame and a rear ladder frame comprises a front ladder frame fixing support arranged on the front ladder frame, a rear ladder frame fixing support arranged on the rear ladder frame, hinge shafts and sliding hinge screws, wherein the front ladder frame fixing support and the rear ladder frame fixing support are movably hinged through the hinge shafts. One ends of the sliding hinge screws are connected with the rear ladder frame fixing support, and the other ends of the sliding hinge screws are arranged in a sliding groove of the front ladder frame fixing support and can slide along the sliding groove; or one ends of the sliding hinge screws are connected with the front ladder frame fixing support, and the other ends of the sliding hinge screws are arranged in a sliding groove of the rear ladder frame fixing support and can slide along the sliding groove. Due to the sliding hinge screws, the number of contact points between the front ladder frame and the rear ladder frame is increased, the ladder is good in stability when bearing force in the direction of the hinge shaft, and the connection position of the front ladder frame and the rear ladder frame is ensured to be firm. In addition, the connection structure of the front ladder frame and the rear ladder frame can rotate freely, does not deform after long time use, and greatly improves use safety.
Description
Technical field
The utility model relates to a kind of syndeton of preceding terraced frame with the terraced frame in back of ladder.
Background technology
The preceding terraced frame of the various ladder of releasing on the market at present and the terraced frame in back; The connecting hole of terraced frame and the terraced frame in back before generally directly running through with rotating shaft; With this two is coupled together, preceding terraced frame can rotate freely with the terraced frame in back around the shaft, thereby the expansion of realization ladder uses and gathering is deposited.But when current terraced frame was connected with the terraced frame in back side by side, the design length of rotating shaft this moment is for the longest, and was stressed for the poorest, and can force the connecting hole distortion of rotating shaft or preceding/terraced frame in back along with the propelling of time, and then influenced the safe in utilization of ladder.
Summary of the invention
The purpose of the utility model is exactly the deficiency that overcomes prior art, propose a kind of before terraced frame with the back terraced frame syndeton, can not be out of shape along with the propelling of time, improve the safety in utilization of ladder greatly.
For realizing above-mentioned purpose; The syndeton of terraced frame and the terraced frame in back before the utility model is a kind of; Comprise terraced frame before being located at preceding terraced frame fixed mount, be located at back terraced frame fixed mount, hinge and the slip anchor of the terraced frame in back, said before terraced frame fixed mount be movably hinged through hinge and the terraced frame fixed mount in back, said slip anchor one end is connected with back terraced frame fixed mount; Before being located at, the other end also can slide in the chute of terraced frame fixed mount along this chute; Perhaps, said slip anchor one end is connected with preceding terraced frame fixed mount, also can slide along this chute in the chute of terraced frame fixed mount after the other end is located at.
Closed or semi-enclosed frame cover before terraced frame fixed mount can be and is enclosed within before said on the terraced frame, the terraced frame fixed mount in said back can be the closed or semi-enclosed frame cover that is enclosed within on the terraced frame in back.Terraced frame before terraced frame fixed mount can be fixed at through rivet before being somebody's turn to do, the terraced frame fixed mount in this back can be fixed at the terraced frame in back through rivet.
In one embodiment, before said terraced frame fixed mount be movably hinged through hinge and the terraced frame fixed mount in back hinge axis hole that the hinge axis hole that is provided with for preceding terraced frame fixed mount and the terraced frame fixed mount in back be provided be enclosed within respectively hinge two ends and can be around this hinge rotation.
In one embodiment, the sliding end of said slip anchor is provided with chute and cooperates the bayonet socket that slides, the preferred groove of this bayonet socket.
Tie point between the terraced frame fixed mount of preceding terraced frame fixed mount of the utility model and back has two places, and the one, connect also and can rotate through hinge around hinge, the 2nd, connect through the slip anchor, realize the spacing of hinge direction.
The utility model is owing to designed the slip anchor; So increased the contact point between the terraced frame of preceding terraced frame and back; Make ladder stability when receiving the power of hinge direction better, terraced frame is firm with the junction of the terraced frame in back before guaranteeing, and free to rotate; Can not be out of shape, improve the safety in utilization of ladder widely along with the propelling of time.

The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
Extremely shown in Figure 8 like Fig. 1; The syndeton of terraced frame and the terraced frame in back before the utility model embodiment is a kind of; Comprise terraced frame 1 before being located at preceding terraced frame fixed mount 6, be located at back terraced frame fixed mount 7, hinge 9 and the slip anchor 8 of the terraced frame 5 in back, preceding terraced frame fixed mount 6 is the closed frame cover on the terraced frame 1 before being enclosed within, the terraced frame fixed mount 7 in back is for being enclosed within the closed frame cover on the terraced frame 5 in back; Before terraced frame fixed mount 6 be fixed at through rivet 3 before terraced frame 1, the back terraced frame fixed mount 7 through rivet 3 be fixed at the back terraced frame 5.Before terraced frame fixed mount 6 be movably hinged through hinge 9 and the terraced frame fixed mount 7 in back, specifically: the hinge axis hole 71 that the hinge axis hole 61 that preceding terraced frame fixed mount 6 is provided with and the terraced frame fixed mount 7 in back are provided be enclosed within respectively hinge 9 two ends and can be around these hinge 9 rotations.Slip anchor 8 one ends are fixedly connected with the terraced frame fixed mount 7 in back, also can slide along this chute 62 in the chute 62 of terraced frame fixed mount 6 before the other end is located at, and the sliding end of this slip anchor 8 is provided with chute 62 and cooperates the bayonet socket 81 that slides, and this bayonet socket 81 is a groove.
Shown in figure 10; The direction of arrow is exactly the force direction that receives of hinge 9 owing to designed slip anchor 8, so before closely contact between the terraced frame fixed mount 7 of terraced frame fixed mount 6 and back; The axis of hinge 9 and slip anchor 8 remains vertical with the contact surface of preceding terraced frame fixed mount 6 and the terraced frame fixed mount 7 in back; Its stress is ideal, makes ladder contact surface when launching and draw in stable, has increased the stability of ladder.
As shown in Figure 8, the preceding terraced frame fixed mount 6 of the utility model embodiment is closed frame cover with the terraced frame fixed mount 7 in back, and is as shown in Figure 9 certainly, and the preceding terraced frame fixed mount 6 of the utility model can be semi-enclosed frame cover with the terraced frame fixed mount 7 in back.
Slip anchor 8 one ends of the utility model embodiment are connected with the terraced frame fixed mount 7 in back, also can slide along this chute 62 in the chute 62 of terraced frame fixed mount 6 before the other end is located at.Certainly, also can be designed to: slip anchor 8 one ends are connected with preceding terraced frame fixed mount 6, also can slide along this chute in the chute of terraced frame fixed mount 7 after the other end is located at.Action effect is the same.
