Abstract
The utility model relates to a herringbone ladder carrier plate and a herringbone ladder. The herringbone ladder carrier plate comprises a carrier plate body which comprises a top end plate, a first side panel and a second side panel, wherein the first side panel and the second side panel are arranged at two sides of the top end plate; a laminating board capable of being attached and connected to the top end of a ladder rod of the herringbone ladder after the herringbone ladder is opened is arranged below the top end plate. Therefore, the laminating board is completely attached and connected to the top end of the ladder rod of the herringbone ladder after the herringbone ladder is opened, not only is the stability of connection increased, but also two edges can be attached to each other without cutting the top of the main ladder rod to form bevel angles.
Description
Technical field
The utility model belongs to double ladder technical field, is specifically related to a kind of double ladder top board and double ladder.
Background technology
The moulding of double ladder top board, is to determine in use one of the important indicator of integral rigidity quality of this ladder, is also more parts of recruitment relatively in production and processing.In addition, the size after folding also has a certain impact to packing and transportation.Shown in Figure 1, existing double ladder top board is trench structure, and groove inside dimension is wider than main terraced bar, can not with the fine combination of main terraced bar, and the top of main terraced bar also wants bevell just can make the laminating of two limits.
Utility model content
The purpose of this utility model is to solve the problems of the technologies described above and a kind of double ladder top board and double ladder is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of double ladder top board, comprise top board body, described top board body comprises headboard and is positioned at the first side panel of described headboard both sides, the second side panel, the below of described headboard be provided with one for after opening at double ladder can with the terraced masthead end of the described double ladder jointing plate being connected that fits.
Described jointing plate one end is fixedly connected with described the first side panel, the other end be connected in described headboard and described the second side panel to closing place, and form triangular structure with described headboard and described the first side panel.
The downward development length of described the first side panel is greater than the downward development length of described the second side panel.
The purpose of this utility model is also to provide a kind of double ladder, comprises top board, and described top board adopts described double ladder top board.
The utility model by below the headboard at double ladder top board, be provided with one for after opening at double ladder can with the terraced masthead end of the described double ladder jointing plate being connected that fits, thereby can be after double ladder be opened, the terraced masthead end of described jointing plate and described double ladder is fitted and connected completely, not only increased the stability connecting, and the top of main terraced bar does not need bevell just can make two limit laminatings again.
Accompanying drawing explanation
Figure 1 shows that the structural representation of existing double ladder top board;
Figure 2 shows that the structural representation of the double ladder top board that the utility model embodiment provides.
The specific embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Refer to Fig. 1, a kind of double ladder top board, comprise top board body, described top board body comprises headboard 1 and is positioned at the first side panel 1 of described headboard both sides, the second side panel 3, the below of described headboard 1 be provided with one for after opening at double ladder can with the terraced masthead end of the described double ladder jointing plate 4 being connected that fits.
Owing to being provided with described jointing plate, can make three limits and the main terraced bar of top board fit, main terraced bar has also saved a section oblique angle trouble, and labor and material saving, has increased stability.
Further, described jointing plate one end is fixedly connected with described the first side panel, the other end be connected in described headboard and described the second side panel to closing place, and form triangular structure with described headboard and described the first side panel.
Because headboard and jointing plate, the first side panel connect into the trench structure of triangle, the existing double ladder trench structure of ratio of rigidity has improved several times, has improved the integral rigidity of ladder.
Further, the downward development length of described the first side panel is greater than the downward development length of described the second side panel.
The utility model by below the headboard at double ladder top board, be provided with one for after opening at double ladder can with the terraced masthead end of the described double ladder jointing plate being connected that fits, thereby can be after double ladder be opened, the terraced masthead end of described jointing plate and described double ladder is fitted and connected completely, not only increased the stability connecting, and the top of main terraced bar does not need bevell just can make two limit laminatings again.
The purpose of this utility model is also to provide a kind of double ladder, comprises top board, and described top board adopts described double ladder top board.
Due to double ladder top board described in top board employing the utility model embodiment of described double ladder, there is the corresponding technique effect that described double ladder top board brings.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
