Abstract
The utility model discloses a ladder with a safety protection structure. The ladder comprises a ladder body, wherein the ladder body comprises two ladder bodies, wherein each ladder body comprises left and right ladder legs; a fixed shaft is arranged on the left ladder leg of the first ladder body and connected with a connecting rod mechanism; the connecting rod mechanism comprises a first connecting rod; one or more protruding tacks are arranged on the side surface of the first connecting rod; the protruding tacks are blocked into fixed holes formed in a second connecting rod; one or more fixed holes are uniformly formed in the second connecting rod at intervals; a boss is arranged at the head end of the second connecting rod; a neck is formed in the left ladder leg of the second ladder body. The protruding tacks are blocked into the fixed holes, and then the boss is put into the neck; the ladder cannot continuously be opened due to limit of the connecting rod mechanism when the ladder legs expand, and the shape is fixed, so as to prevent a person from falling off from the ladder. The ladder is simple in structure, convenient to fabricate and install, and strong in practicability, and the use safety of the ladder is improved.
Description
Technical field
The utility model relates to a kind of ladder with safety protection structure, belongs to ladder field.
Background technology
Existing staggered form ladder is widely used in different occasions, and this ladder in use, opens support on the ground by four ladder legs of ladder, and people steps down on the pedal between support or in the gripper shoe of a top of the trellis and carries out operation.But this ladder is found through using, there is the deficiency of 2 broad aspect: 1, while using under the environment of ground smoother, because people stands in support top, frictional force between frame bottom and ground is smaller, support can open and become yi word pattern under the effect of people's gravity, and the people who stands in ladder top can drop from eminence, and health is caused serious injury.2, when this ladder is used, side must have 1 to 2 people to hold the ladder, and avoids ladder to slide.Just once met workman drops from ladder the situation of getting off to cause broken feet to applicant.Although have part ladder that the rope of security protection is also installed in side in existing ladder, rope the first insufficient strength is easily disconnected, the second rope is in use bad highly regulates its length according to the use of ladder.
Summary of the invention
The purpose of this utility model is: a kind of ladder with safety protection structure is provided, solves when existing ladder is used and there will be because ladder opens, the problem that while causing people to fall fallen situation and the use of this ladder from eminence, the multiple people of needs could use.
The technical solution of the utility model: a kind of ladder with safety protection structure, include ladder body, this ladder body includes 2 secondary ladders, every secondary ladder includes two ladder legs in left and right, on the left ladder leg of the first ladder, be provided with fixed axis, fixed axis is connected with linkage, described linkage includes first connecting rod, on first connecting rod side, be provided with 1 or 1 above protruding nail, protruding nail snaps in the fixing hole being provided with on second connecting rod, more than 1 or 1 fixing hole is evenly spaced apart and arranged on second connecting rod, second connecting rod head end is provided with 1 lug boss, on the left ladder leg of the second ladder, be provided with draw-in groove.
Above-mentioned a kind of ladder with safety protection structure, is provided with holddown groove on the left ladder leg of described the first ladder.
Above-mentioned a kind of ladder with safety protection structure, is provided with the structure identical with left ladder leg on the right ladder leg of two width ladders of described ladder body.
The beneficial effects of the utility model: when the utility model is used, by the protruding nail of first connecting rod is snapped in the fixing hole of second connecting rod, thereby two connecting rods are fixed, avoided it to occur rotating, then lug boss is put into draw-in groove.When the gravity that is subject to people when ladder leg opens, the restriction that is subject to linkage cannot continue to open, and its shape is fixed, thereby avoids people to drop from ladder top.When ladder does not need to use, linkage is snapped in holddown groove, avoid linkage in ladder moving process to rock everywhere.This utility model is simple in structure, makes, installs more convenient, practical, has improved the safety that ladder is used, and has good use value, and in use procedure, does not need other people to be assisted, and has saved human and material resources.
Accompanying drawing explanation
Structural representation when accompanying drawing 1 is use of the present utility model;
Accompanying drawing 2 is structural representation while not using of the present utility model;
Accompanying drawing 3 is the main TV structure schematic diagram of linkage of the present utility model;
The left ladder leg of Reference numeral: 1-the first ladder, 2-fixed axis, 3-linkage, the left ladder leg of 4-the second ladder, 5-draw-in groove, 6-first connecting rod, 7-second connecting rod, 8-fixing hole, the protruding nail of 9-, 10-lug boss, 11-holddown groove.
The specific embodiment
Embodiment of the present utility model: a kind of ladder with safety protection structure, as shown in accompanying drawing 1-2, include ladder body, this ladder body includes the same ladder of 2 parafacies, on the left ladder leg 1 of the first ladder, be provided with fixed axis 2, fixed axis 2 is connected with linkage 3, and linkage 3 can rotate around fixed axis 2, on the left ladder leg 4 of the second ladder, is provided with draw-in groove 5.
This ladder in use, by the protruding nail 9 on first connecting rod 6 is snapped in the fixing hole 8 on second connecting rod 7, after ladder leg is opened, the lug boss on second connecting rod 7 10 is snapped in the draw-in groove 5 of the left ladder leg 4 of the second ladder, now between first connecting rod 6 and second connecting rod 7, strut and be in line.When the gravity that is subject to people when ladder leg opens to two, this linkage 3 can limit opening of support, fixes the shape of ladder, avoids people to drop from ladder.This ladder is by regulating the angle between ladder leg to obtain different height, because evenly compartment of terrain is provided with multiple fixing holes 8 on second connecting rod 7, only the protruding nail 9 on first connecting rod 6 need to be snapped in the fixing hole 8 of diverse location, just can fix the ladder of differing heights.
On the left ladder leg 1 of the first ladder, be also provided with holddown groove 11, as shown in Figure 2, when ladder does not need to use, linkage 3 put into the holddown groove 11 on the left ladder leg 1 of the first ladder, can avoid ladder to rock in moving process everywhere.
For the safety of using, suggestion is provided with the structure identical with left ladder leg on the right ladder leg of two width ladders, thereby improves the usage safety performance of ladder.And preferably each 2 same covering devices, raising usage safety performance installed on the left and right ladder leg of two width ladders.
