Abstract
The utility model belongs to the technical field of connection devices of steel tubes, and particularly relates to a steel tube connector for connection of the steel tubes. The steel tube connector is characterized by being composed of steel tube sleeves (1), fixing screws (3) and a central stop rod (4). The central stop rod (4) is arranged in the middle portion of the steel tube sleeves (1), the steel tube sleeves (1) on the two sides of the central stop rod (4) are respectively provided with one fixing screw (3), the fixing screws (3) are fixedly installed in fixing screw holes in the steel tube sleeves (1), and preferentially, thickened steel plates (2) are welded to the portions of the fixing screws (3) on the steel tube sleeves (1). The steel tube connector has the advantages of being convenient to use and maintain, long in service life, low in manufacturing cost, capable of being repeatedly used and high in safety factor, is fixed firmly, does not slide, and is good in economic and social benefit.
Description
One, technical field: the utility model belongs to the linkage technical field of steel pipe, particularly a kind of steel tube connection head connected for steel pipe.
Two, technical background: being connected to many places and all will using of steel pipe, but mainly use on building site scaffolds erecting, existing in the connection of steel pipe, basically the instrument used is the fixed card of centre with the little axle of casting, and use this instrument to carry out when steel pipe connects existing using inconvenience, and application life is short, cost is high, the deficiency that safety factor is low, it is mainly manifested in the little axle fatiguability of casting and damages, when casting little axle after fatigue damage, the fastening means of this steel pipe is just scrapped fully, be that it can not continue to have used again, sometimes it casts the whether fatigue damage of little axle, observe and also be difficult for differentiating by people's eyes, can only measure and could determine by instrument, therefore its installation and use are also inconvenient.
Three, summary of the invention:
The purpose of this utility model is for the prior art above shortcomings, and develop a kind of novel steel tube connection head, this steel tube connection head can overcome the above-mentioned deficiency that prior art is brought effectively, it has easy to use, long service life, cost is low, and the safety factor advantages of higher has economic and social benefit preferably.
Its technical scheme is: see shown in accompanying drawing 1 and accompanying drawing 2, the feature of this steel tube connection head is that it is comprised of steel pipe sleeve (1), standing screw (3), center pin (4) three parts, center pin (4) is located at the middle part in steel pipe sleeve (1), respectively be provided with a standing screw (3) on the steel pipe sleeve (1) on center pin (4) both sides, standing screw (3) is packed in the fixing threaded hole on steel pipe sleeve (1).Because the wall thickness of steel pipe sleeve (1) is thinner, when fixing standing screw (3), intensity is lower, easily come off, locate to weld one and add steel plate (2) therefore be preferably in standing screw (3) on steel pipe sleeve (1), to increase the constant intensity of standing screw (3).Center pin (4) can be soldered or alternate manner be fixed on the middle part in steel pipe sleeve (1).
Steel tube connection head of the present utility model is applicable to use in the connection of all steel pipes, during use, the steel pipe that needs are connected is inserted in an end of steel pipe sleeve (1), and top is to steel pipe sleeve (1) Nei center pin (4), finally be about to steel pipe and be fixed on firmly in steel pipe sleeve (1) tightening standing screw (3), also can fix an other steel pipe in the other end of steel pipe sleeve (1), when fixing each root steel pipe, only need to tighten a standing screw (3) gets final product, its use is very convenient, and standing screw (3) is sturdy and durable, its long service life, fixing of it is also very firm, its safety factor is higher, center pin (4) can make the permanent position of steel pipe for best, be in the center in steel pipe sleeve (1), so its fixed effect the best.
This steel tube connection head can effectively overcome the above-mentioned deficiency that prior art is brought, and it is convenient that it has operation and maintenance, long service life, and cost is low, and repeatedly Reusability, fix firm not landing, and the safety factor advantages of higher, have economic and social benefit preferably.
Four, accompanying drawing explanation:
The main TV structure schematic diagram that Fig. 1 is steel tube connection head.
The standing screw that Fig. 2 is Fig. 1 (3) structure for amplifying schematic diagram.
In Fig. 1: 1, steel pipe sleeve; 2, add steel plate; 3, standing screw; 4 center pins.Below in conjunction with embodiment, be described in detail.
Five, the specific embodiment:
Embodiment 1: Fig. 1 and Fig. 2 can be used as the specific embodiment of the utility model structural representation.The feature of steel tube connection head is that it is by steel pipe sleeve (1), standing screw (3), pin (4) three parts in center form, center pin (4) is located at the middle part in steel pipe sleeve (1), respectively be provided with a standing screw (3) on the steel pipe sleeve (1) on center pin (4) both sides, standing screw (3) is packed in the fixing threaded hole on steel pipe sleeve (1), in order to increase the wall thickness of steel pipe sleeve (1), standing screw (3) on steel pipe sleeve (1) is located to weld one and is added steel plate (2), to increase the constant intensity of standing screw (3), add the degree of depth that steel plate (2) can be increased in the fixing threaded hole on steel pipe sleeve (1).
Claims (2)
1. a steel tube connection head, it is characterized in that it is comprised of steel pipe sleeve (1), standing screw (3), center pin (4) three parts, center pin (4) is located at the middle part in steel pipe sleeve (1), respectively be provided with a standing screw (3) on the steel pipe sleeve (1) on center pin (4) both sides, standing screw (3) is packed in the fixing threaded hole on steel pipe sleeve (1).
