Abstract

A universal connector of a safety barrier is a pipe connector used to connect handrails into an integral barrier, which comprises a connector body, the connector body is formed by integrally connecting a left connector arm, a right connector arm and a connector seat, the left connector arm and the right connector arm surround the connector seat to rotate in positive and negative directions, the universal connector and the handrails are assorted to assemble into the barrier, the direction of the universal connector can be changed by rotating the left connector arm and the right connector arm in optional directions according to needs, simultaneously, the direction of the handrails which is integrally connected with the universal connector also can be changed, the existing barrier formed by fixing connectors can not make a turn, and needs increasing the quantity if turning is required, the barrier connected by the universal connectors can make a turn, thereby the barrier can not to be limited by the shape and the position of places, can meet different requirements, is wide in use range, and convenient and flexible in use, additionally, the connector seat is further provided with a knob with threads which can be fixed on a vertical column of the barrier.

Description

The safety barrier universal joint

Technical field

The utility model relates to the union that a kind of each railing that will constitute guardrail connects into whole usefulness, and particularly a kind of rotating union can change the position of guardrail and the safety barrier universal joint that direction is used arbitrarily.

Background technology

Guardrail is mainly as the spacer of separating, separating, use when isolating, and especially at road construction and engineering construction scene, for the protection personal safety does not allow non-constructor enter the construction important place, the special guardrail of placing is noted with the caution reminds people.Especially in power system, need often to safeguard, maintain, rush to repair; sometimes also need hot line job; but the electricity with eyes be cannot see impalpable; do not resemble the engineering construction scene and do not put guardrail; far awayly also just can see and carefully to dodge, so guardrail but is one and plays the requisite facility of safeguard protection in power system.

But the guardrail that existing power system is used all is fixed, make according to shape, size, the position of job site and arrive on-the-spot the installation then, and versatility is very poor, therefore need make the joint and the length railing of polytype and specification and then select for use.The time spent is not collected in storehouse, floor space is difficult for keeping greatly, patches firmly for making the joint railing, also is equipped with by metal material to make the elastic ring that collar and pellet shot from a slingshot constitute on the union end, but the time easily gets rusty with long metal elastic ring rust jail can not rotated, and therefore patches difficulty, it is inconvenient to use.

Patent No. CN02261306.4 " a kind of union that is used for the connection of guardrail railing ", it is connected a railing and and is connected between the railing, the union body that comprises a moulding, one trepanning that matches with the railing end is arranged at the body bottom, end face has an elasticity buckling piece at least, the elasticity buckling piece pushes the jack that into is connected railing, engaging firmly is connected railing with regard to energy fast after releasing power, firm connection, easy for installation, the work efficiency height, profile is salubrious, attractive in appearance, third dimension is strong, but it is fixed that this union is still, can not rotate and can change direction, function singleness uses limitation very big.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of safety barrier universal joint is provided, use with the supporting guardrail that is assembled into of railing, these joint fabrication and installation are simple and convenient, assembling, dismounting are rapidly, fast, do not need instrument, can change the arbitrarily angled and direction of joint as required, the direction and the position of railing thereby change fuses with it, use not to be subjected to the restriction of generality of fabricating yard strong no limitation.

The technical scheme in the invention for solving the above technical problem is that the safety barrier universal joint comprises fittings body, the integral body that described fittings body is connected into by left and right joint arm and plinth, the forward and reverse rotation of described left and right joint arm energy solderless wrapped connection headstock.

Compared with prior art, advantage of the present utility model is: former joint is fixed, can not rotate and to change direction and angle, this universal joint is by a left side, the right connector arm is socketed on the plinth and constitutes, but any direction rotates as required, also changed simultaneously direction and the position that connects into whole railing with it, be not subjected to the place shape, the influence of position, no limitation, the scope of application is wide, and is easy to use, flexibly, dress, tear open conveniently, rapidly, do not need instrument, be connected with threaded knob on the side surface of joint, can be fixed on be connected firmly on the up-and-down rod of guardrail stable, the guardrail that connects into of the universal joint use of can turning round thus.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Left and

right joint arm

1,5 is identical two parts, one side has left and right through hole 6,7 to cooperate with plinth 2, in addition side has left and right blind hole 11,12 to cooperate with an end of horizontal bar bar 13, and left and right through hole and left and right blind hole are orthogonal, as Fig. 1, Fig. 2, shown in Figure 3.

Have through hole 3 to cooperate with the right cylinder 16 of railing in the middle of the plinth 2, both sides be symmetrical left and right ladder post 10,8, and inwall is the ladder blind hole, and there is boss 9 usefulness of the band screw knob 4 that has been threaded the lower front surface centre, as shown in Figure 2.

Left and

right joint arm

1,5 is socketed in respectively to flexibly connect on the left and right ladder post 10,8 in plinth 2 both sides and is integral, as Fig. 1, shown in Figure 3.

Left and right joint arm can rotate in 270 degree scopes clockwise or counterclockwise around the left and right ladder post 10,8 on the plinth 2, change the locality of left and

right joint arm

1,5, thereby change position and the direction that patches horizontal bar bar 13 in the left and right blind hole of left and right joint arm.

In the tight respectively left and right blind hole of inserting on the left and

right joint arm

1,5 11,12 of one end of two horizontal bar bars 13, in the through hole 3 in the middle of the right cylinder 16 insertion plinths 2, again the other end of straight railing 14 two ends by tee junction 15 and horizontal bar bar 13 connected and composed guardrail, as Fig. 5, shown in Figure 6.
