Description

Technical Field

[0001] This utility model relates to the field of ladder elbow technology, specifically to an elbow device formed on a segmentable ladder. Background Technology

[0002] The toggle mechanism (also known as a hinge or joint) of a ladder is a key component in ladder design, especially in telescopic or folding ladders. The toggle allows different parts of the ladder to move relative to each other, enabling the ladder to stretch, retract, and fold, and ensuring sufficient strength and stability during use.

[0003] However, the toggle joint device lacks sufficient adjustment precision during use, making it difficult to accurately control the unfolding angle of the ladder. This can lead to instability during ladder use, affecting its normal operation. Furthermore, the toggle joint device cannot achieve quick, convenient, and stable segmentation, failing to meet users' needs for flexible ladder length adjustment in different scenarios.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an elbow device formed on a segmentable ladder to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A toggle device formed on a segmentable ladder includes a segmentable ladder toggle frame, connecting mechanisms on both sides of the segmentable ladder toggle frame, a limiting mechanism on the side of the connecting mechanisms, and auxiliary components installed on the connecting mechanisms and the segmentable ladder toggle frame. The auxiliary components include multiple auxiliary plates fixedly installed on the segmentable ladder toggle frame and the connecting mechanisms by connecting straps. One end of two auxiliary plates is fixed with a snap-fit ​​seat by the connecting strap, and one side of the snap-fit ​​seat snaps into the segmentable ladder toggle frame and the connecting mechanism. One end of the auxiliary plate is connected to an adjusting cylinder, and multiple auxiliary holes are opened above the adjusting cylinder. Adjusting rods pass through the inner walls of the auxiliary holes. Adjusting holes are evenly distributed on the auxiliary plate, and one of the adjusting holes is threadedly connected to one end of the adjusting rod.

[0008] Furthermore, in order to better fold and adjust the segmented ladder, the connecting mechanism includes connecting elbow seats one fixed on both sides of the segmented ladder elbow frame one, a connecting rod passing through the connecting elbow seat one, a connecting elbow seat two passing through the surface of the connecting rod, a segmented ladder elbow frame two connected to one side of the connecting elbow seat two, one end of an auxiliary plate being fixedly installed on the segmented ladder elbow frame two by a connecting strap, and one side of the segmented ladder elbow frame two being snapped into place with a snap-fit ​​seat.

[0009] Furthermore, in order to better restrict the elbow joints of the ladder segment and improve their stability, the restriction mechanism includes a restriction groove and a restriction cavity respectively opened on one side of the ladder segment elbow joint frame 2 and the ladder segment elbow joint frame 1. A restriction plate is snapped into the inner wall of the restriction cavity of the ladder segment elbow joint frame 1, and multiple restriction screws are threaded onto the restriction plate. Multiple connection holes are opened on the inner wall of the restriction groove of the ladder segment elbow joint frame 2, and the inner wall of the connection hole is adapted to one end of the restriction screw.

[0010] Furthermore, in order to better assist in restricting the first and second sections of the ladder elbow, a number of restricting blocks are fixed on one side of the first section of the ladder elbow, and a number of restricting holes are opened on one side of the second section of the ladder elbow, with the inner wall of the restricting hole engaging with one end of the restricting block.

[0011] Furthermore, in order to improve the anti-slip properties of the second and first sections of the ladder joint, multiple anti-slip pads are provided on the second and first sections of the ladder joint, and anti-slip grooves are provided on the anti-slip pads.

[0012] Furthermore, multiple anti-slip sleeves are provided at one end of the second and first sections of the ladder elbow frame, and the anti-slip sleeves are adapted to one end of the second and first sections of the ladder elbow frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting a limiting mechanism in the connecting mechanism, it is easy to quickly limit the elbow of the segmented ladder, prevent unnecessary displacement between the first elbow frame and the second elbow frame of the segmented ladder during use, and avoid instability of the ladder during use. At the same time, the auxiliary mechanism set in the connecting mechanism and the first elbow frame of the segmented ladder can realize fine adjustment of the ladder unfolding angle, thereby effectively solving the problem of insufficient adjustment accuracy.

[0015] (2) By setting the connecting mechanism in the first segment of the ladder elbow frame, the convenience and stability of the segment connection are improved, meeting the user's need for flexible adjustment of the ladder length in different scenarios. At the same time, the anti-slip pads and anti-slip sleeves set in the second segment of the ladder elbow frame and the first segment of the ladder elbow frame can effectively increase the friction between the ladder and the ground or contact surface, prevent the ladder from sliding during use, and further improve the stability and safety of the ladder.

Multiple limiting screws 302 are threaded on the limiting plate 301. There are two limiting screws 302. Multiple connecting holes are opened on the inner wall of the limiting groove of the segmented ladder elbow frame 204. The inner wall of the connecting hole is adapted to one end of the limiting screw 302. There are two connecting holes for connecting with the limiting screw 302.

[0027] One side of the first section of the ladder elbow bracket 1 is fixed with multiple limiting blocks 5, two in number, for stability at the elbow of the ladder.

[0028] Example 2:

[0029] like Figures 1-4As shown, according to an embodiment of the present invention, an elbow joint device formed on a segmentable ladder is provided. An auxiliary component 4 is installed on the connecting mechanism 2 and the segmentable ladder elbow joint frame 1. The auxiliary component 4 includes a plurality of auxiliary plates 401 fixedly installed on the segmentable ladder elbow joint frame 1 and the connecting mechanism 2 by a connecting strap. One end of two auxiliary plates 401 is fixed with a snap-fit ​​seat 404 by a connecting strap. One end of the other two auxiliary plates 401 can rotate or move on the segmentable ladder elbow joint frame 1 and the segmentable ladder elbow joint frame 204.

One side of the segmentable ladder elbow joint frame 204 is snapped into the snap-fit ​​seat 404. One end of the auxiliary plate 401 is connected to an adjusting cylinder 402.

[0030] Multiple auxiliary holes are provided above the regulating cylinder 402. There are two auxiliary holes. An regulating rod 403 passes through the inner wall of the auxiliary hole.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In summary, with the help of the above-mentioned technical solution of this utility model, when it is necessary to extend the ladder section, the operator connects the adjacent ladder sections through the connecting mechanism 2. The first and second ladder joint brackets 204 are hinged through the connecting rod 202. The connecting rod 202 passes through the connecting elbow seat 201 and the connecting elbow seat 203 to form a rotating and unfolded A-shape. Then the operator uses the locking seat 404 to connect the first and second ladder joint brackets 204 respectively. After being removed from the side, it is snapped into the side of the first and second sections of the ladder elbow frame 204. Then, the operator rotates the adjusting rod 403 set on the adjusting cylinder 402. The adjusting rod 403 is aligned with the adjusting hole opened in the auxiliary plate 401, so that the auxiliary plate 401, the adjusting cylinder 402 and the first and second sections of the ladder elbow frame 204 form a triangular stable structure, which can transfer the load to the first and second sections of the ladder elbow frame 204.

[0033] When the ladder needs to be unfolded into a straight line, the operator rotates the first and second sections of the ladder elbow frame 204 around the axis of the connecting rod 202. At this time, the limiting block 5 set on the first section of the ladder elbow frame 204 is embedded in the limiting hole of the second section of the ladder elbow frame 204 to form a preliminary positioning. After unfolding into place, the limiting plate 301 is inserted from the limiting cavity of the first section of the ladder elbow frame 201 into the limiting groove of the second section of the ladder elbow frame 204 to provide shear resistance. The limiting screw 302 set on the limiting plate 301 is rotated so that its end is screwed into the connecting hole of the limiting groove to prevent lateral displacement. The anti-slip sleeve 7 covers the ends of the first and second sections of the ladder elbow frame 204, forming a high friction interface between the first and second sections of the ladder elbow frame 204 and the contact surface.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
