Abstract
The utility model discloses a pin connection technology used in the electric fitting part, and includes a straight-pole shape pin rod. The utility model is characterized in that a convex body whose outer diameter is bigger than that of the pin rod is positioned at the both ends of the pin rod; the attachment point of the convex body and the pin rod is transit with a stair surface which is vertical to the pin rod; the outside of the convex body that is far away from the end of the pin rod is a smooth arc curved surface. When being installed, the convex body or a hat is held, the convex body with arc curved surface is penetrated into a workpiece connection hole with force application, then the arc curved surface leads the overall convex body to another end of the workpiece, and the right angle stair surface transition between the pin rod and the convex body plays the role of self-locking. Therefore, the utility model is simply and reasonably structured, advantageous for manufacturing and fast installment, and the technology has good connection stability.
Description
Technical field
The utility model discloses a kind of connection pin technology that is used on the electric armour clamp parts.
Background technique
People become pin with steel or stainless steel or copper; be applied on electric armour clamp interval rod and the anti-dizziness ball and play interconnect function; this pin has cylindricality pin rod body; one end is provided with the cap body of external diameter greater than this body diameter of pin rod, the other end then be provided with perpendicular to the pin rod body shaft to pin-and-hole, when the connection electric armour clamp; also need the supporting little latch suitable with the pin-and-hole diameter; what have also establishes outside thread in the pin-and-hole inboard of pin rod body, connects with nut again, plays the effect of duplicate protection.The connected element of this connecting means is many, and production process is numerous and diverse, also is unfavorable for on-the-spot quick mounting, and the structure of the Security of its connection simultaneously and little latch, nut has confidential relation.
The model utility content
The utility model purpose is to design a kind ofly to be manufactured simply, is easy to install, the self-locking pin of the reliable electric armour clamp of switching performance.
The utility model comprises straight-bar shape pin rod body, be characterized in being provided with the convex body of external diameter greater than this body diameter of pin rod at the two ends of pin rod body, this convex body and pin rod body joint with perpendicular to the pin rod body shaft to the step surface transition, convex body is smooth arc-shaped curved surface away from the outer end of pin rod body.
During installation, hand-held convex body or hand-held cap body, the convex body that will have arc-shaped curved surface penetrates the workpiece attachment hole application of force slightly, and arc-shaped curved surface just drives whole convex body and arrives the workpiece the other end, and the right angle platform terrace transition between pin rod body and convex body can be played the effect of self-locking.Therefore, the utility model is simple and reasonable for structure, be convenient to make, and is beneficial to quick mounting, and its connection stability is also better.
For cooperating other parts of electric armour clamp to play spacing effect, the utility model also is provided with the cap body in the outer end of a convex body.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is another structural representation of the present utility model.
Among the figure, 1,1 ' pin rod body, 2,2 ' cap body, 3,3 ' convex body, 4,4 ' step surface.
Specific embodiment
Among Fig. 1, the two ends of cylindrical pin rod body 1 are respectively equipped with two convex bodys 3 of external diameter greater than pin rod body 1 external diameter, the outer end of the convex body 3 in left side is provided with the cap body 2 greater than convex body 3 external diameters, 3 of pin rod body 1 and convex bodys are by being connected perpendicular to pin rod body 1 axial step surface 4, and convex body 3 exterior edge faces on right side are arc-shaped curved surface.The external diameter of above-mentioned step surface 4 is greater than the external diameter of pin rod body 1.
Among Fig. 2, cylindrical pin rod body 1 ' two ends be respectively equipped with external diameter greater than two convex bodys 3 of pin rod body 1 ' external diameter ', two convex bodys 3 ' the exterior edge face all be arc-shaped curved surface.
Claims (2)
1, a kind of self-locking pin of electric armour clamp, comprise straight-bar shape pin rod body, it is characterized in that being provided with the convex body of external diameter greater than this body diameter of pin rod at the two ends of pin rod body, this convex body and pin rod body joint with perpendicular to the pin rod body shaft to the step surface transition, convex body is smooth arc-shaped curved surface away from the outer end of pin rod body.
2, according to the claim duty state the self-locking pin, it is characterized in that being provided with the cap body in the outer end of a convex body.
