Abstract
The utility model relates to a self-locking device, which comprises an L-shaped main body, wherein the L-shaped main body comprises a position limiting rod and a hook rod; the upper part of the position limiting rod is connected with a position limiting shaft on the right side of the position limiting rod through a tension spring; the position limiting shaft is arranged on a door frame above the hook rod; the lower end of the position limiting rod is connected with the left end of the hook rod; a V-shaped hook is arranged at the right end of the hook rod; the distance between the V-shaped hook and the door frame is larger than the thickness of a door plate; a rotating shaft is arranged at the connecting part of the position limiting rod and the hook rod; the L-shaped main body is movably connected with the door frame through the rotating shaft; and a rubber pad is arranged on the right side of the door frame. The self-locking device has the beneficial effects that the structure is simple, the manufacturing cost is low, the mounting and the use are facilitated, manual operation is not needed in the locking process, and the problem that as a cage door is provided without a locking device in the building construction process, a plate tilting gate is likely to be automatically opened in the running process of a cage of an elevator due to errors of working staff, and goods or the working staff in the cage can fall off the cage to result in safety accidents is solved.
Description
Technical field
The utility model relates to a kind of self-locking device.
Background technology
Construction elevator is a kind of lifting appliance that vertically transports staff and material in the building construction process, mainly is made up of guide rail bracket, cage and transmission device.The cage door of hoist is to be made up of the lever gear door of the first half and the plate-turning door of Lower Half.Owing to have construction elevator cage door now mechanical locking device is not set in the course of work; In the elevator craning cage running; Exist and to cause plate-turning door to open automatically because of staff's error, the potential safety hazard that causes article in the cage or personnel to fall in the cage.
The utility model content
The purpose of the utility model provides a kind of self-locking device; Solve existing construction elevator cage door mechanical locking device is not set; In the elevator craning cage running; Exist and to cause plate-turning door to open automatically because of staff's error, the potential safety hazard that causes article in the cage or personnel to fall in the cage.
The purpose of the utility model is to realize through following technical scheme:
A kind of self-locking device; Comprise L shaped main body, said L shaped main body comprises gag lever post and hook bar, and gag lever post top is connected with right-hand limit shaft of gag lever post through back-moving spring; Limit shaft is arranged on the doorframe of hook bar top; The gag lever post lower end is connected with hook bar left end, and hook bar right-hand member is provided with the V-arrangement hook, and the distance between V-arrangement hook and the doorframe is greater than the thickness of door-plate; Said gag lever post is provided with turning cylinder with the junction of hook bar, and said L shaped main body flexibly connects through turning cylinder and doorframe.Said doorframe right side is provided with rubber pad.
The beneficial effect of the utility model is: simple in structure; Low cost of manufacture; Easy to install, in the locking process, need not manually-operated, solved that the cage door does not have locking device in the building construction process; In the elevator craning cage running, cause plate-turning door to open automatically, cause in the cage article or staff to fall in the cage and produce the problem of security incident because of staff error.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the described a kind of self-locking device of the utility model embodiment.
Among the figure:
1, L shaped main body; 101, gag lever post; 102, hook bar; 1021, V-arrangement hook; 2, back-moving spring; 3, limit shaft; 4, doorframe; 5, door-plate; 6, turning cylinder; 7, rubber pad.
The specific embodiment
As shown in Figure 1, the described a kind of self-locking device of the utility model embodiment comprises L shaped main body 1; Said L shaped main body 1 comprises gag lever post 101 and hook bar 102; Gag lever post 101 tops are connected with the gag lever post 101 right-hand limit shafts 3 through back-moving spring 2, and limit shaft 3 is arranged on the doorframe 4 of hook bar 102 tops, and gag lever post 101 lower ends are connected with hook bar 102 left ends; Hook bar 102 right-hand members are provided with V-arrangement hook 1021, and the distance between V-arrangement hook 1021 and the doorframe 4 is greater than the thickness of door-plate 5; Said gag lever post 101 is provided with turning cylinder 6 with the junction of hook bar 102, and said L shaped main body 1 flexibly connects through turning cylinder 6 and doorframe 4.Said doorframe 4 right sides are provided with rubber pad 7.
The described self-locking device of the utility model embodiment flexibly connects through turning cylinder 6 and doorframe 4; 2 pairs of gag lever posts 101 of back-moving spring apply pulling force to the right; The V-arrangement hook 1021 of hook bar 102 right-hand members is moved down, and carry out spacing through 3 pairs of V-arrangement hooks 1021 of gag lever post 101 and limit shaft.When door-plate 5 cut out, the collision through the 5 pairs of V-arrangements of door-plate hook 1021 made door-plate 5 enter into V-arrangement and links up with 1021 inboards, by V-arrangement hook 1021 door-plate 5 is hooked, thus door-plate 5 machineries are locked; When opening door-plate 5, the V-arrangement hook 1021 of linking up with bar 102 right-hand members is upwarped and door-plate 5 disengagings, can reach convenient purpose of opening door-plate 5 through moving gag lever post 101.In order to cushion and make door-plate 5 to contact more closely with doorframe 4 to the door-plate 5 and the collision of doorframe 4, doorframe 4 right sides are provided with rubber pad 7.
The described self-locking device of the utility model embodiment is simple in structure; Low cost of manufacture; Easy to install, in the locking process, need not manually-operated, solved that the cage door does not have locking device in the building construction process; In the elevator craning cage running, cause plate-turning door to open automatically, cause in the cage article or staff to fall in the cage and produce the problem of security incident because of staff error.Being specially adapted to construction elevator cage plate-turning door installs and uses.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection domain of the utility model.
