Description
Technical field
The utility model relates to outdoor goods technical field, particularly a kind of gapless web member central contact pin-jointed structure of foldable tent frame girder truss.
Background technology
Tent determines that its product structure must possess the folder function that can realize overall shrinkage and expansion because of the feature that it uses out of doors.Commercial tent then should possess usage space and highly enough large commercial function simultaneously.
Existing commercial foldable tent is primarily of tent rack and tarpaulin component composition.Tent rack (hereinafter referred to as paulin frame) is then general to be made up of column, foldable truss Liang He center top mechanism section assembly.
The foldable truss beam assembly of paulin frame is made up of two movable web member group activity pivot joints.Web member is rectangle pipe material component, and its lengthwise centers and two ends have three pivoted holes.Often organize web member group to consist of centre bore activity pivot joint two web members, two groups of web member groups then consist of the pivoted hole of its one end and two three-dimensional joint pivot.
The column assembly of paulin frame is the support component of tent.Generally filled by outer tube and interior pipe box and form, interior pipe is fixedly connected with column pin and stands on ground, and outer tube can along interior pipe lifting moving.The anchor tip of band pivoted hole is housed on outer tube top, and appropriate place, below is provided with slip joint planar development extreme position locating hole.Outside pipe suit is with the slip joint that can move up and down along outer tube of pivoted hole, when slip joint move to outer tube preset planar development extreme position locating hole time, the resilient pin established in it will realize in automatic patchhole this slip joint planar development extreme position location.
Complete paulin frame should have four (or more) column assembly, stand on ground configuration by square vertices (or more summit, edge point).Each folding girder truss assembly passes through anchor tip and the pivot joint of slip joint pivoted hole of its non-pivot end pivoted hole and adjacent two column assemblies, forms the whole peripheral frame of paulin frame thus.When the slip joint on column be in column tube lowermost position put time, paulin frame is in contraction state, and when level pulls four column assemblies, slip joint rises along outer tube, until after being positioned planar development extreme position locating hole, paulin frame realizes plane and launches completely.The height that then can realize paulin frame when promoting the outer tube of four column assemblies after hood frame planar development again regulates.
The center ceiling mechanism assembly of paulin frame is made up of center ceiling mechanism and the pivot joint of four web member groups.Three-dimensional joint middle point vertical direction pivoted hole pivot joint on the other end pivoted hole of web member group and corresponding girder truss assembly, thus realize the function servo-actuated with paulin frame peripheral frame.
In prior art, the web member of foldable tent frame girder truss connects the mode all adopting center pivoted hole to be flexibly connected.Often organize the scissor movable composition of composition one.For preventing phase mutual friction between two web members, collision, between web member, in addition pad isolation to make to keep this stable gap between web member, thus must ensure that girder truss has the function of freely launching and shrinking.In existing technology, between web member, isolation is general adopts flat shim structure.Because flat shim thickness immobilizes, therefore its thickness must be less than the mounting distance between web member, otherwise can cause tent rack bite, blunt when the motion launched and shrink, and the serious tent rack that also can make cannot use.Therefore in the prior art, web member pivotal fit must be that wide arc gap coordinates.Just because of this wide arc gap coordinates the defect making this foldable tent general show off existence and stability difference.For improving this defect, improve foldable tent and launch stability, this case produces thus.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of foldable tent frame girder truss web member central contact pin-jointed structure to be rigidly connected by wide arc gap and change into the connection of gapless elasticity, thus improve the pin-jointed structure that tent rack launches stability in use.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A gapless web member central contact pin-jointed structure for foldable tent frame girder truss, adopts a ripple pad to carry out web member isolation between two web members; Produce elasticity after described ripple pad has compression thus make contact point structure have gapless, low friction resilient pivot joint feature.
Further, ripple pad is a concentric ring washer, the annular entity of pad is formed around this axis rotation sweep by the rectangle plane of pad axis by one, during scanning, rectangle plane two long limits scan out the axial pressure-bearing curved surface of two, pad, minor face scans out pad outer circumference surface and endoporus internal face, during scanning, minor face away from axis a sinusoidal path up-down vibration should scan on pad outer circumference surface, sine curve cycle on full circle cylinder is three cycles, and amplitude appropriate rationally should be greater than the clearance distance between the first web member and the second web member; Described ripple pad should, macromolecular material manufacture that good rigidly, friction factor low high by intensity.
Further, the first protective pad watt, the second protective pad watt, the first web member, the second web member, the first connector and the first connector is also comprised.
The beneficial effect of the web member contact point structure of tent rack girder truss of the present utility model is:
In the web member central contact pin-jointed structure of described foldable tent frame girder truss, ripple pad is adopted to isolate between first web member, the second web member, because ripple pad gross thickness is greater than the distance between two web members, so when web member combination group is in confined state.Ripple pad is in compressive state and has elasticity.Simultaneously because ripple pad one side only has three crests, only have three uniform straight lines with web member contact surface.Due to the described macromolecular material manufacture that ripple pad is high by intensity, good rigidly, friction factor are low, therefore, in described central contact pin-jointed structure, frictional resistance has dropped to minimum.
In sum, the web member central contact structure of tent rack girder truss of the present utility model has gapless, low friction resilient pivot joint feature.Should have equally easy and flexible can launch and shrink with the foldable tent frame of this anatomical connectivity general assembly, have again the feature that sound construction is stable.
