Abstract
The utility model relates to a duplex bulb for a transmission line, which belongs to ball bowl type hardware fitting of the transmission line. A coupling head is a U-shaped double coupling head composed of connectors (1), (2). The utility model has the advantages that a hanging plate connected to an opening of the utility model has balanced stress and is difficult to crack, etc. The utility model is especially suitable for erecting transmission lines in areas with bad natural environment and climatic conditions.
Description
The utility model relates to the ball bowl like gold utensil in the transmission line, especially is connected in the bulb between link plate and the insulator.
Bulb of the prior art, its coupling head is the simply connected link, as shown in Figure 3, it can only be nested with U type link and connect in that insulator string is short need not adorn link plate the time with link, when when adjusting insulator string length and under U type link, be hinged with link plate, if still adopt the simply connected link and the other end Bolt Connection of link plate, link plate just can only single face and link be abutted against, easily cause link plate two sides discontinuity equalization, rupture because of shearing force is excessive.
The purpose of this utility model provide in order to overcome above-mentioned the deficiencies in the prior art part just a kind of with can guarantee that the link plate two sides is stressed evenly after link plate connects, the ball bowl like gold utensil of easy fracture not.
The purpose of this utility model is achieved by the following technical solution.
It is that the U type duplex joint that become by two joint groups is made in coupling head; Opening distance between two is 20-35mm.
Because coupling head is the U type duplex joint that two joint groups become, when being connected with link plate, link plate is inserted in the opening between two, attachment bolt is passed successively in the connecting hole of duplex joint and link plate and the two is connected, the duplex joint is connected in the two sides of link plate symmetrically, make link plate two sides stress equalization, not easy fracture.
Below in conjunction with drawings and Examples the utility model is further elaborated.
Fig. 1 is a front view of the present utility model,
Fig. 2 is a left view of the present utility model,
Fig. 3 is the front view of prior art simply connected bulb,
Fig. 4 is the left view of prior art simply connected bulb,
At first as shown in Figure 1 and Figure 2, go out the duplex bulb with the whole forging of carbon constructional quality steel, coupling head is forged into the U type duplex joint that become by 1,2 liang of joint group, the opening between two coupling heads 1,2 is apart from being 25mm.During assembling, link plate is inserted in the opening between 1,2, pass the connecting hole of duplex joint and link plate termination successively, be equipped with nut 6 again and closed pin 7 gets final product with connecting bolt.The utility model has machinery and serviceability preferably through evidence, is specially adapted to use when the more abominable area of natural environment and weather conditions erects power transmission lines.
Claims (2)
1, transmission line duplex bulb, by coupling head (1), (2), connecting rod (3) bulb (4), attachment bolt (5), nut (6) are formed, and it is characterized in that the U type duplex joint that coupling head is served as reasons (1), (2) two joint groups become.
2, duplex bulb according to claim 1 is characterized in that, the opening between two coupling heads (1), (2) is apart from C=20-35mm.
