Description

A kind of connection structure of assembly type dry-type transformer case
Technical field
The utility model belong to assembly type dry-type transformer manufacturing field more particularly to a kind of assembly type dry-type transformer The connection structure of shell.
Background technique
With the continuous development of Dry-Transformer Technology, the form for becoming shell is done also by two kinds of forms of integral type and assembly type Gradually change to the assembly type of more flexible multiplicity.Traditional assembling form mostly uses greatly a large amount of bolt or tapping screw to fix It is dry to become shell, it is unfavorable for that assembling is rapidly completed.
Summary of the invention
In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a kind of assembly type dry-type transformer cases Connection structure quickly can be connected and be fastened to the dry framework for becoming shell, reduce the work that difficulty of construction improves working efficiency With.
To achieve the above object, the utility model is achieved through the following technical solutions:
A kind of connection structure of assembly type dry-type transformer case, including left locating piece, right locating piece, positioning pin, fastening Screw, left locating piece, right locating piece are respectively welded on transformer case and transformer body frame, left locating piece, right positioning The mounting hole to match with positioning pin outer diameter, the positioning pin that left locating piece, right locating piece pass through insertion mounting hole are equipped on block Connection, fastening screw are threadedly coupled with left locating piece, right locating piece, and positioning pin both ends are limited by fastening screw.
The connection structure is two or more, and transformer case and transformer body frame pass through more than two connection structures Connection.
The left locating piece, right locating piece are square structure.
The left locating piece or right locating piece is equipped with positioning protrusion, sets on transformer case or transformer body frame There is the through-hole with positioning protrusion grafting.
Compared with prior art, the utility model has the beneficial effects that
The utility model, which is realized, carries out the dry top cover for becoming shell of assembly type and base foundation and transformer body frame Quickly connection and fastening;Reach connection and tight by the interaction of rectangular locating piece, positioning pin and the fastening screw at both ends Gu the effect of assembly type dry-type transformer case, playing the role of, which reduces difficulty of construction, improves working efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the portion the I enlarged drawing of Fig. 1.
Fig. 3 is the structural schematic diagram of right locating piece.
Fig. 4 is the schematic diagram of transformer body frame.
In figure: 1- transformer case 2- fastening screw 3- left locating piece 4- positioning pin 5- right locating piece 6- transformer Main body frame 7- connection structure 8- positioning protrusion 9- square hole.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings of the specification, it should be noted that the utility model Implement embodiment not limited to the following.
See Fig. 1, Fig. 2, a kind of connection structure 7 of assembly type dry-type transformer case, including left locating piece 3, right locating piece 5, positioning pin 4, fastening screw 2, left locating piece 3, right locating piece 5 are respectively welded at transformer case 1 and transformer body frame 6 On, the mounting hole to match with 4 outer diameter of positioning pin, left locating piece 3, right locating piece 5 are equipped in left locating piece 3, right locating piece 5 Positioning pin 4 by being inserted into mounting hole connects, and fastening screw 2 is threadedly coupled with left locating piece 3, right locating piece 5, and 4 liang of positioning pin End is limited by fastening screw 2.See Fig. 3, Fig. 4, for convenience of welding, left locating piece 3 or right locating piece 5 are equipped with positioning protrusion 8, Transformer case 1 or transformer body frame 6 are equipped with the through-hole with 8 grafting of positioning protrusion;For convenience of processing, positioning protrusion 8 To be rectangular, through-hole is square hole 9.
See Fig. 1, which is two or more, and transformer case 1 and transformer body frame 6 pass through two or more The connection structure 7 connection.Left locating piece 3, right locating piece 5 are square structure, to facilitate production, and facilitate installation.
Fig. 1, Fig. 2 are seen, by taking top cover is fixedly connected with transformer body frame 6 as an example, respectively on the top of transformer case 1 Left locating piece 3, right locating piece 5 are welded on lid, transformer body frame 6, when top cover and transformer body frame 6 contact, left and right The mounting hole of locating piece 3,5 is in same axis, and by positioning pin 4 through in mounting hole, left locating piece 3,5 distal end of right locating piece are It is threadedly coupled with fastening screw 2, positioning pin 4 is limited in mounting hole.Top cover is limited with the upper of transformer body frame 6 with this The displacement of lower front and back.More than two companies are set at the top cover of transformer case 1, the lateral connection of transformer body frame 6 Binding structure 7 can be arranged at symmetrical position, and similarly, two to four companies are arranged in the length of each seamed edge of transformer case 1 Binding structure 7, and in such a way that opposite face is arranged symmetrically, it interacts, keeps entire assembly type dry-type transformer case 1 fixed.
The utility model is realized to the dry top cover and base foundation for becoming shell of assembly type, transformer body frame 6 Left and right side frame, front and back side frame are quickly connected and are fastened;Pass through the fastening screw 2 of rectangular locating piece, positioning pin 4 and both ends Interaction achieve the effect that connection and fastening assembly type dry-type transformer case 1, play reduce difficulty of construction improve work The effect of efficiency.
