Description

Clamp rail

technical field

The utility model relates to the related field of linear sliding rails, in particular to a clamping rail.

Background technique

As far as the linear slideway is concerned, when the slider is about to enter or exit the slideway, it is easy for the rolling elements (such as balls or rollers) to fall out of the slider. Under the holding effect of the clamping rail, it will not be detached arbitrarily.

The current linear slides are roughly divided into two different forms, such as face-to-face (DF) and back-to-back (DB). Different clamping rails are produced, but this will inevitably increase the cost of developing the mold, and it will also take more time to confirm whether it is the corresponding clamping rail during assembly. Relevant patent documents such as TW I263001, TW I441989 or JPA_2002106560 cannot effectively solve the problem that the clamping rails cannot be shared.

In addition, the shortest distance between the first holding surface and the third holding surface is smaller than that between the second holding surface and the second holding surface. The third keeps the shortest distance between faces.

It can be seen from the above that when the clamp rail of the present invention is used with a face-to-face (DF) linear slide rail, the two left and right first holding surfaces and the left and right third holding surfaces provide a holding effect for the rolling elements. When used with a back-to-back (DB) linear slide rail, the clamp rail of the present invention is turned upside down, so that the clamp rail of the present invention utilizes the left and right second holding surfaces and the left and right third holding surfaces. Provides a holding effect to the rolling elements. In other words, the clamp rail of the present invention is suitable for two different types of linear slide rails, so there is no need to develop another set of molds, so as to save the mold development cost and increase the convenience of use.

Detailed ways

The applicant first explains here that in the entire specification, including the embodiments described below and the claims in the scope of the patent application, the terms related to the directionality are based on the directions in the drawings. Next, in the embodiments to be introduced below and the accompanying drawings, the same element numbers represent the same or similar elements or their structural features.

Please refer to FIG. 2 , the clamping rail 10 is symmetrical with respect to a first imaginary plane P1 , and the left and right halves of the clamping rail 10 respectively have a first end wall 12 and a second end wall parallel to the first end wall 12 . 14. A first vertical wall 16, a second vertical wall 18 parallel to the first vertical wall 16 and a third vertical wall 20 parallel to the first vertical wall 16 and the second vertical wall 18, wherein the first end wall 12 and the first vertical wall 16. The spaces are connected together by a first holding wall 22, the first vertical wall 16 and the third vertical wall 20 are connected together by a third holding wall 30, and the second vertical wall 18 and the third vertical wall 20 are connected by a second holding wall The walls 26 are connected together, and the second end wall 14 and the second retaining wall 26 are connected together via the second vertical wall 18 . In addition, the left and right halves of the clamping rail 10 also have a first obliquely extending wall 34 and a second obliquely extending wall 36 respectively. The other ends of the first obliquely extending walls 34 are connected to each other, so that a first V-shaped groove 38 is formed between the two first obliquely extending walls 34, and one end of the two second obliquely extending walls 36 is connected to the two second end walls respectively. 14. The other ends of the two second obliquely extending walls 36 are connected to each other, so that a second V-shaped groove 40 is formed between the two second obliquely extending walls 36, and the first V-shaped groove 38 and the second V-shaped groove 40 are formed. Symmetrical up and down, the first V-shaped groove 38 and the second V-shaped groove 40 can further increase the structural flexibility, so as to facilitate assembly.
