Description

Industrial heavy-load telescopic guide rail limited by limiting pin

Technical Field

The utility model belongs to the technical field of guide rail equipment, and relates to an industrial heavy-load telescopic guide rail limited by a limiting pin.

Background

The limiting function of the conventional industrial heavy-duty telescopic guide rail on the market is realized by the collision of limiting blocks on the inner rail and the outer rail with the end face of the bottom of the retainer. Because the interval of keeping the bottom very little in ware bottom and the outer rail, in order to make the stopper on the inner rail can with keep ware bottom end face effectively collide, the stopper installation back on the inner rail is very close to the bottom in the outer rail, consequently in the use, just the bottom in the outer rail is strikeed easily to the slight atress deformation of inner rail or skew, and the noise produces, bottom surface in the outer rail of scratch, influences the result of use.

Disclosure of Invention

Aiming at the problems, the utility model provides an industrial heavy-load telescopic guide rail limited by a limiting pin, which can effectively avoid collision of an inner rail and an outer rail during telescopic motion.

According to the technical scheme of the utility model: an industrial heavy-load telescopic guide rail limited by a limiting pin comprises an outer rail, an inner rail and the outer rail are connected in a sliding fit mode, a steel ball is mounted in a V-shaped channel formed between the inner rail and the outer rail, and the steel ball is limited and fixed through a retainer; the method is characterized in that: two ends of the inner bottom of the outer rail are respectively riveted with a limiting block so as to limit the retainer;

and limiting pins are arranged on the side surfaces of the two ends of the inner rail in the length direction.

As a further improvement of the utility model, two ends of the inner bottom surface of the outer rail in the length direction are respectively riveted with two limit blocks, and the two limit blocks limit the end surface of the retainer.

As a further improvement of the utility model, each end of the inner rail in the length direction is respectively provided with a limit pin, and the limit pin limits the retainer.

As a further improvement of the utility model, the holder is made of steel plate.

The utility model has the technical effects that: the product of the utility model has simple, reasonable and ingenious structure, and is purposefully improved aiming at the problem that the inner rail possibly slips off from the outer rail when the existing heavy-duty slide rail works. The inner rail and the outer rail of the utility model can play a limiting role when moving in two directions relatively.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings.

In fig. 1 to 4, the device comprises a limit pin 1, an outer rail 2, a steel ball 3, a retainer 4, a limit block 5, an inner rail 6 and the like.

As shown in fig. 1 to 4, the utility model relates to an industrial heavy-load telescopic guide rail, which comprises an outer rail 2, an inner rail 6 is connected with the outer rail 2 in a sliding fit manner, a steel ball 3 is arranged in a V-shaped channel formed between the inner rail 6 and the outer rail 2, the steel ball 3 is limited and fixed by a retainer 4, and the inner rail 6 and the outer rail 2 realize reciprocating telescopic motion through rolling of the steel ball 3; in order to prevent the steel balls 3 and the holder 4 from falling out, a limit part must be used to limit the travel of the rail.

The structure for limiting the inner rail 6 and the retainer 4 is as follows: the stopper 5 is riveted respectively at outer rail 2's interior bottom both ends to keep ware 4 spacing, make keep ware 4 only can move between two stoppers 5, guaranteed to keep ware 4 and steel ball 3 can not run out outer rail.

In order to ensure that the inner rail 6 cannot slip off from the outer rail 2, the side surfaces of the two ends of the inner rail 6 in the length direction are provided with limit pins 1. When the inner rail 6 moves to the limit position, the limit pin 1 collides with the end faces at the two sides of the retainer 4, and the inner rail 6 is limited from sliding outwards.

In concrete practice, two stopper 5 are riveted respectively at outer rail 2's interior bottom surface length direction both ends, and two stopper 5 carry on spacingly to the terminal surface that keeps ware 4, keep ware 4 to adopt the steel sheet to make, keep ware 4 evenly arranges steel ball 3.

It will be appreciated that in particular practice, one stop pin 1 is provided at each end of the inner rail 6 in the length direction, the stop pin 1 defining a stop for the retainer 4.

The product of the utility model has reasonable and ingenious structure, and can effectively avoid the inner rail 6 from slipping relative to the outer rail 2 in practice, thereby ensuring the stable and reliable operation of the sliding rail.
