Abstract
The utility model relates to a connecting mechanism applied on climbing frames for children, in particular to a safety tube connecting means applied in cross connection of two tubes. The utility model is mainly used to settle the existing technical problems that connecting mechanism tubes and other tubes are fixed by welding after connection and it is not easy to disassemble and install; and the two cross tubes are merely welded and fixed by welding which suffers poor strength, and where a bolt pair is used, hidden safety trouble may exist in the screw cap, and as well as other problems. The utility model comprises a mounting piece (1) provided with a bolt hole, a bolt (2) is provided in the bolt hole. The utility model is characterized in that the diameter of the mounting piece (1) is smaller than the cavity of the tube to be mounted; the height of the mounting piece (1) is greater than the diameter of the cavity of the tube to be installed; the external length of the bolt (2) is greater than the outer diameter of the other tube to be mounted.
Description
Technical field
The utility model relates to a kind of use and climbs bindiny mechanism on the frame children, especially relates to a kind of to using in the bursting tube linkage structure aspect the two pipe interconnections.
Background technique
With trampoline and so on sports equipment is example; basically be the elasticity tension face that between framework, is provided with a tensioned state; the user can carry out various jumping on this elasticity tension face; for making whole elasticity tension mask that required flexible tension force nargin be arranged, this elasticity tension face can be set at the needed height place by foot rest usually.And the elasticity tension face that this type of trampoline ammunition feed is jumped is typically provided with sizable area, so its framework also must be provided with bigger diameter, so can't make with single tubing, must form to take over to engage piecemeal.Chinese patent discloses a kind of trampoline safety fences guard bar joint construction (publication number: CN2571421Y), it is made of the peripheral frame of a location spring face the frame pipe of pegging graft each other in twos, the affixed downwards weak point arm of frame pipe lands with the grafting trampoline and the pipe end that connects of supporting tripods is connected, and affixed another nipple of above-mentioned short arm side is connected with the pipe end that connects of the safe fences guard bar of pegging graft.Affixed short arm and nipple are the hollow tube of deciding diameter, and the pipe end that connects of foot rest and guard bar is then to dwindle pipe end and its grafting in footpath.Short arm and frame pipe and and nipple between all fixing to weld.But the connection between this bindiny mechanism tube and tube all is fixing with welding after pegging graft, and dismounting is all inconvenient; And two pipes arranged in a crossed manner are only fixing by welding, cause insufficient strength.
Summary of the invention
The purpose of this utility model provides a kind of bursting tube linkage structure, and it mainly is that the connection that solves between the existing in prior technology bindiny mechanism tube and tube all is fixing with welding after pegging graft, and dismounting is all inconvenient; And two pipes arranged in a crossed manner are only fixing by welding, cause insufficient strength, and as using the bolt pair, there is the technical problem of potential safety hazard etc. in nut.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Bursting tube linkage structure of the present utility model, include the fixed block of a band screw, bolt is arranged in the screw, its feature at described fixed block diameter less than the tube chamber for the treatment of fixed tube, the height of fixed block is greater than the lumen diameter for the treatment of fixed tube, and the outer length of described bolt is treated the external diameter of fixed tube greater than another.Fixed block is used for fixing vertical tube arranged in a crossed manner and transverse tube, and vertical tube inside can be socketed with the body of fixed block.
As preferably, described fixed block is a tubular type, has through hole on its tube wall, is inserted with bolt in the through hole, and fixed block inside is provided with tapped hole, and an end of bolt is fixed in the tapped hole.Fixed block body hollow, the through hole that has on the body with open mounting hole on vertical tube, transverse tube with coaxial.Vertical tube and transverse tube can be mutually the right angle setting, and the vertical tube end is connected on the pipe shaft of transverse tube.The fixed block body is plugged in the end of vertical tube mounting end, guarantees that mounting hole on its through hole, tapped hole and vertical tube, the transverse tube is on same shaft axis.
As preferably, described fixed block inner card is provided with square nut, and described tapped hole is located in the square nut.The body of fixed block can be provided with step, make that square nut can be stuck in above.One end of fixed block can have and can make square nut insert the opening of body inside.Square nut can be a rectangle.
As preferably, described fixed block inside is provided with axial stiffening rib, and it is coaxial with through hole to have the hole on the stiffening rib.Stiffening rib can guarantee to keep the stability of bolt when long bolt inserts installation; And stiffening rib can be located square nut.
As preferably, described fixed block one end is provided with flange, and the flange diameter is more than or equal to the vertical tube diameter.Flange can seal an end of vertical tube, and anti-sealing, dust enter the body inside of pipe to be installed.
As preferably, the through hole that has on the described fixed block tube wall is two of symmetry.
Therefore, the Placement that the utlity model has between the tube and tube all is fixedly connected by the fixed block of band screw, and dismounting all comparatively makes things convenient for the characteristics of characteristics; Characteristics such as the utility model also has two pipes arranged in a crossed manner by filling in the fixed block of pipe to be installed inside and being connected of bolt, need not to use the nut that exposes, and intensity is stronger, and is simple and reasonable for structure.
