Abstract
The utility model relates to an improved connecting member of a ladder, which comprises a ring body. The utility model is characterized in that the ring body is provided with a connecting ring part clamped on a ladder frame, and elastic teeth which can be elastically opened, collected and closed are evenly distributed and arranged on an inner circular part around an inner circle. A connecting sheath of the utility model has the advantages of simple structure and convenient assembly. A ladder treading roller and a ladder frame made of non-metal materials such as plastic materials or glass fibre reinforced plastic materials can be connected tighter and stabler.
Description
Technical field
The utility model belongs to the ladder field, the coupling compoonent of especially terraced frame and ladder riding club.
Background technology
Known ladder connecting piece as disclosed Chinese patent CN01136450.5, has been introduced a kind of glass fibre reinforced plastic insulating stepladder, relates to connecting piece.
And for example disclosed Chinese patent 200420000446.6 relates to can describe the end cover of pillar and stair tread port buckle closure securing member from propping up column wall by articulated elements and end cover, fixedlys connected with stair tread.
Known technology is at the connection defective tightness of the connection fit on of tubular pillar and horizontal riding club, particularly glass fiber reinforced plastic shapes pillar and horizontal riding club and firm.
Summary of the invention
Problem to be solved in the utility model is to overcome the defective that aforementioned techniques exists, and a kind of connection ladder frame of plastic-steel or the use of glass fiber reinforced plastic shapes ladder and coupling compoonent of terraced riding club of more being applicable to is provided.
The utility model solves its technical problem and takes following technical scheme to realize, the coupling compoonent of a kind of improved ladder that provides according to the utility model, comprise a ring body, wherein, described ring body has the connection ring portion of holding on terraced frame, but its inner circular part around the uniform setting elasticity of interior circle open receive and Elastic Teeth.
The utility model solves the also available following technical scheme of its technical problem and further realizes:
The coupling compoonent of aforesaid improved ladder, wherein, the root of described Elastic Teeth is along the elasticity tooth of justifying in the body into ring row, and the tooth portion of Elastic Teeth has the tip of expansible holding in the limiting groove of riding club.
The coupling compoonent of aforesaid improved ladder, wherein, a tensioning that becomes tight fit to be connected with hollow riding club is stifled, combines with ring body coupling.
The coupling compoonent of aforesaid improved ladder, wherein, circle was set to the wheel hub of hollow out in described tensioning was stifled;
The coupling compoonent of aforesaid improved ladder, wherein, described tensioning is stifled be provided with end support that riding club laterally collects together flange.
The utility model compared with prior art has significant advantage and beneficial effect.By above technical scheme as can be known, the utility model has following advantage at least under the structure configuration of excellence:
1. the utility model connection jacket structure is simple, easy to assembly, can make the terraced riding club and tightr, the firm connection of terraced frame of non-metallic material such as plastic material or glass fiber reinforced plastic material.
2. the ladder that has aforementioned coupling compoonent effectively raises steadiness, the safety of ladder, makes lighter and handier, more firm, the more affine audient of ladder; And its structure makes ladder assembling more convenient, goes smoothly.
The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the utility model cross-sectional view;
Fig. 2 is the stifled side-looking structural representation of tensioning in the utility model;
Fig. 3 is the stifled decomposition texture schematic diagram of body and tensioning;
Fig. 4,4a are the utility model and terraced frame and terraced riding club assembling back schematic diagram.
The specific embodiment
Below in conjunction with preferred embodiment, to according to the specific embodiment provided by the invention, feature and effect thereof, describe in detail as after; For simple and purpose clearly, hereinafter appropriate omission the description of known technology, in order to avoid those unnecessary details influences are to the description of the technical program.
See also Fig. 1-4, a kind of coupling compoonent of improved ladder comprises a ring body 1, and wherein, described ring body has the connection ring portion 12 of holding on terraced frame, but its inner circular part around the uniform setting elasticity of interior circle open receive and Elastic Teeth 11; The root 110 of described Elastic Teeth is along the elasticity tooth of justifying in the body into ring row, tooth portion 111 expansibles of Elastic Teeth, and its crown portion cooperates limiting groove 21 cards of riding club to stop riding club laterally to collect together,
One tensioning that becomes tight fit to be connected with hollow riding club is stifled 10, constitutes the coupling assembling that the terraced frame of acting from inside in coordination with forces attacking from outside combines with riding club with the ring body.
Circle was set to the wheel hub 101 of hollow out in described tensioning was stifled; Tensioning is stifled be provided with end support that riding club laterally collects together flange 102; Can tightly bite tap-tap rod 2 with terraced riding club assembling.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
