Description
Technical Field
The utility model relates to an electric power fitting technical field specifically is a first gold utensil of interior bushing type double ball socket closed bowl.
Background
The socket hanging plate is a connecting fitting used in overhead power lines and substations, and is generally used for connecting insulator fitting strings or connecting a wiring fitting of a stay wire tower with the tower.
As shown in fig. 4, the current lining type closed socket is composed of a ball socket-shaped lining 8 and a hanging plate 9 which are connected into a whole, the shape of the hardware connected with the socket-shaped lining is in a ball head shape, the hardware connected with the hanging plate in a corresponding manner is a connecting plate, when two ball head hardware are required to be connected respectively, two socket-shaped hanging plates are required, the hanging plate ends of the two socket-shaped hanging plates are connected into a whole through an eccentric plate, the two socket-shaped linings are connected with the ball head of the hardware respectively, so that the connection process is complicated, the product structure is complex, and the product cost is increased.
In addition, in order to prevent the ball head from falling off from the ball socket, the conventional socket clevis is usually locked in the socket by a W-shaped pin, an R-shaped pin, a V-shaped pin, an L-shaped pin or an additional hoop. Generally, the ball head is difficult to fall off from the socket of the bowl head. However, after the alternating action of wind power for a long time, some locking pins with weaker pin bodies lose the locking effect due to long-term extrusion deformation or breakage. And some locking pins such as W-shaped pins have complicated structures and are inconvenient to install.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a first gold utensil of bowl is sealed to two ball sockets of interior bushing type can effectively solve the problem among the background art.
The technical scheme for realizing the purpose is as follows: the utility model provides a first gold utensil of welt formula double ball nest closed which characterized in that: including the bowl head inside lining, the upper portion and the lower part of bowl head inside lining are provided with ball socket respectively and hang the groove, the cover of the outer detachable of bowl head inside lining is equipped with the overcoat, and the overcoat is connected as whole through bolt, nut with the middle part of bowl head inside lining.
Furthermore, the bowl head lining is a cylinder provided with a hollow cavity and is formed by the involution of a left side lining and a right side lining which are symmetrically arranged.
Furthermore, the centers of the two ends of the left side lining and the right side lining are provided with center holes communicated with the hollow cavity, the center hole at the upper end and the hollow cavity at the upper part of the bowl head lining, and the center hole at the lower end and the hollow cavity at the lower part of the bowl head lining respectively form a ball socket hanging groove.
Furthermore, the outer sleeve is annular and is matched and sleeved on the bowl head lining.
The utility model has the advantages that:
when two ball head fittings are required to be connected respectively, the two ball heads are directly embedded into ball socket hanging grooves at two ends of the bowl head lining respectively, the outer sleeve is sleeved outside the bowl head lining, the outer sleeve and the bowl head lining are connected through the bolts, and the ball heads are sealed in the ball socket hanging grooves at two ends of the bowl head lining through the outer sleeve, so that various locking pins are omitted.
The utility model discloses a both ends are provided with ball socket respectively and hang the groove, can adapt to the gold utensil connection that both ends are the bulb, have simplified the connection structure that both ends are the bulb gold utensil greatly, have reduced manufacturing cost.
The utility model discloses a two ball sockets on the bowl head inside lining hang the groove symmetry and set up and link up each other, can reduce the weight of whole insulator chain to alleviate the load to the shaft tower, thereby improve the security of transmission line operation.
The utility model discloses a bowl head inside lining is to closing formation by the left side inside lining and the right side inside lining that the symmetry set up, and it is convenient to install.

Detailed Description
As shown in fig. 1, 2, 3, the utility model discloses a bowl head inside lining 1, overcoat 2, bowl head inside lining 1 is the cylinder that is provided with cavity 10, and the left side inside lining 1.1 that sets up by the symmetry and right side inside lining 1.2 are to closing the formation, the both ends center of left side inside lining 1.1 and right side inside lining 1.2 is provided with the centre bore 1.3 that communicates cavity 10, the centre bore 1.3 that is located the upper end constitutes first ball socket hanging groove 3 that the opening faces upwards with bowl head inside lining 1 is located the cavity 10 on upper portion, the centre bore 1.3 that is located the lower extreme constitutes second ball socket hanging groove 4 with bowl head inside lining 1 is located the cavity 10 of lower part, overcoat 2 is the annular, and detachable's suit is on bowl head inside lining 1, seal the first ball socket hanging groove 3 at bowl head inside lining 1 both ends through overcoat 2, in second ball socket hanging groove 4, thereby various fitting pins have been saved.
A through bolt hole 5 which is concentrically arranged is arranged between the middle parts of the bowl head lining 1 and the outer sleeve 2, a bolt 6 penetrates through the bolt hole 5, and the tail end of the bolt 6 is connected with a locking nut 7.
As a further explanation of this embodiment, the outer edges of the upper and lower ends of the bowl head liner 1 and the outer sleeve 2 are both provided with arc chamfers.
When specifically using the installation, arrange the bulb gold utensil of one end in first ball socket hangs groove 3, arrange the bulb gold utensil of the other end in second ball socket hangs groove 4, overlap overcoat 2 at last on bowl head inside lining 1 to connect bowl head inside lining 1, overcoat 2 as whole through bolt 6, lock nut 7, thereby seal the bulb in first ball socket of bowl head inside lining 1 hangs groove 3, second ball socket through overcoat 2 and hang the groove 4.
