Abstract
The utility model relates to a connecting pin for a steel pipe supporting frame of a water pond. The utility model mainly comprises a pin and a water-proof shim. The utility model is characterized in that the lower end of the pin is in a circular head shape, and the lower part of the pin can be divided into two branches, wherein the outside of the two branches is respectively provided with a convex point. The water-proof shim is in a bowl shape, and the pin can thread through the water-proof shim and a connecting circular hole of a steel pipe. Then, two convex points of the pin are mutually butted with the edge at the lower end of the connecting circular hole of the steel pipe. The utility model has the advantages that the structure is provided with the water-proof shim, and the pin can easily be inserted and extracted of the water-proof shim; because the thickness of the branches is enlarged, the pin can not be easily broken and bended; the lower end of the pin is in a circular-head shape, which can prevent from hurting a user.
Description
Technical field
The utility model relates to the connection latch of a kind of pond steel pipe support, particularly a kind of connection latch of pond steel pipe support of PVC material.
Background technique
Rectangle or polygon steel pipe holder PVC pond on the present market, steel pipe support normally is made up of limit pipe, T junction, vertical support pipe, and steel tube surface is generally all passed through and is sprayed paint or the plastic-blasting processing.Wherein the reducing of certain-length is processed at the two ends of limit pipe, and T junction was inserted at the contraction position of limit pipe when limit Guan Zaiyu T junction connected, and inserted latch then, and both are fixed.Latch usually adopts has certain flexible plastics to make, and its profile is similar to rivet, and the lower end of latch is provided with two bifurcateds, between two bifurcateds apart from broad, two branches are stuck and are provided with the round table-like or hook-shaped spacing back-off of a circle, referring to Fig. 7.When inserting steel pipe, latch connects circular hole, the both sides bifurcated of latch curves inwardly and makes latch connect circular hole by steel pipe, both sides bifurcated resilience resetted after latch passed steel pipe connection circular hole, and round table-like or hook-shaped spacing back-off is stuck in steel pipe connection circular hole lower edge and plays spacing effect.But this latch exists following defective: the distance between two bifurcateds of 1 this latch is bigger, makes that two bifurcation ratios are thiner, and the pond fills that T junction and limit pipe have very big shearing force to latch after the water, causes the bifurcated bending easily or fractures; The round platform back-off broads of 2 whole circles, cause latch to insert and extract all compare difficult; 3 latch heads are more sharp-pointed, easily the user damaged; 4 do not have water-tight device, and the water capacity easily flows into the corrosion that steel duct causes steel pipe.
Summary of the invention
In order to overcome the defective in the above-mentioned prior art, the utility model is designed the connection latch of a kind of pond steel pipe support.The cylindrical body latch that mainly comprises a similar rivet of the present utility model, cylindrical diameter matches with the Circularhole diameter that is connected of steel pipe, the top of latch is a circular top cover, its diameter is greater than cylindrical diameter, with a waterproof gasket, it is characterized in that: the lower end of described latch is a rounded shape, and from the centre cylindrical bottom is slit into two bifurcateds, the outside of two bifurcateds respectively is provided with a salient point, the salient point shape can be for circular or oval, the height sum of these two salient points is less than the spacing between two bifurcateds, the spacing of cutting apart between two bifurcateds causes two bifurcated bending deflections and latch can be advisable by the connection circular hole of steel pipe swimmingly with the stressed inside extruding of the salient point that allows two branches to stick, and the spacing between two bifurcateds is 1/10～3/10 of a latch cylinder body diameter.The waterproof gasket of being made by rubber or plastics is a bowl-like shape, external diameter is greater than the connection Circularhole diameter of steel pipe, the centre is provided with the circular hole with the latch coupling, and latch passes waterproof gasket, passes the connection circular hole of steel pipe, and two salient points of latch offset with the lower edge that is connected circular hole of steel pipe.
The utility model has the advantages that this structure is provided with waterproof gasket, the latch bayonet socket changes salient point into and inserts and extract easily, and the thickness of bifurcated increases makes latch not frangibility and bending, and the lower end of latch is that rounded shape is avoided the user is damaged.

Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing:
Referring to Fig. 1, Fig. 2, latch 1 is the cylindrical body of a similar rivet, cylindrical diameter matches with the Circularhole diameter that is connected of steel pipe, the top of latch 1 is a circular top cover 5, its diameter is greater than cylindrical diameter, latch 1 usefulness has certain flexible plastics or other material, latch 1 lower end is a round end 6, the bottom of latch 1 is divided into two bifurcateds 2 from the centre with cylindrical 1/3rd, the outside of two bifurcateds 2 respectively is provided with a salient point 7, and salient point 7 shapes can be circular, oval or other shape.The height sum of these two salient points is less than the spacing between two bifurcateds, the width of the branch scarfing 3 between two bifurcateds 2 can be advisable latch 1 for cause two bifurcated 2 bending deflections with the stressed inside extruding of the salient point that allows two branches to stick swimmingly by the connection circular hole of steel pipe, being generally two spacings between the bifurcated is 1/10～3/10 of latch cylinder body diameter.
Referring to Fig. 3, Fig. 4, Fig. 5, Fig. 6, waterproof gasket 4 is made for soft pvc or suitable material such as other flexible rubber or plastics, waterproof gasket 4 be shaped as bowl-type, external diameter is greater than the Circularhole diameter of steel pipe, there is the circular hole with latch 1 coupling the centre.The waterproof gasket 4 of bowl-type makes the internal surface of bowl-type waterproof gasket tightly be fitted in steel tube surface at the Vertical direction compressive deformation, because the position-limiting action of two salient points 7 on the latch 1 has stoped the bounce-back of bowl-type waterproof gasket 4.Can make 4 pairs of steel pipes 8 of waterproof gasket that the excellent waterproof effect is arranged like this, anti-sealing flows into steel duct from the connection circular hole of steel pipe 8.
When steel pipe 8 when being connected with T junction 9, T junction 9 is inserted at the contraction position of steel pipe 8, insert latch 1 then, latch 1 is subjected to the downward power of Vertical direction, and forces the salient point 7 stressed inside extruding on latch bifurcated 2 outer surfaces to cause two bifurcated 2 bending deflections and make latch 1 can pass through the connection circular hole of steel pipe swimmingly.Two bifurcateds 2 have enough thickness to guarantee under the situation of shearing force that is subjected to steel pipe for a long time and repeatedly plug and are not fractureed.Latch 1 runs through after the insertion steel pipe 8, and two salient point 7 resiliences reset and play spacing fixing effect, prevent latch 1 loose or dislocation.
