Y-shaped guide rail

Abstract

The utility model discloses a Y-shaped guide rail. The Y-shaped guide rail comprises a guide rail base, a guide rail body perpendicular to the guide rail base and a rail web connecting the guide rail base and the guide rail body. The guide rail is characterized in that a V-shaped groove is formed in the bottom surface of the guide rail base; the depth of the V-shaped groove is smaller than the thickness of the guide rail base. The depth of the V-shaped groove on the bottom surface of the guide rail base is smaller than the thickness of the guide rail base, so that the thickness of the rail web is increased, the situation that the rail web deforms in the machining process of the guide rail, and products are scrapped is avoided, meanwhile, the use strength of the guide rail can be improved, and the weight of the guide rail is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of guide rails, in particular to a Y-shaped guide rail. Background Art

[0002] As more and more high-rise buildings are being built, the demand for high-speed elevators is also gradually increasing. Most elevators are guide rail type, that is, the car runs along a fixed guide rail during operation. The elevator guide rail is the safety rail for the elevator to travel up and down in the shaft, and is one of the main transmission components for the elevator to go up and down. Elevator guide rails are also provided with guide rail structures of various shapes depending on the usage. In the existing technology, the depth of the groove provided at the bottom of the Y-shaped guide rail is greater than the thickness of the guide rail base, which makes the thickness of the rail waist thinner, making the guide rail easily deformed during the production process, thereby causing the guide rail to be scrapped. At the same time, it also reduces the use strength of the guide rail during use, thereby reducing the service life. To this end, a Y-shaped guide rail that can improve the use strength of the guide rail is proposed. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems and to propose a Y-shaped guide rail.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a Y-shaped guide rail, comprising a guide rail base, a guide rail body arranged perpendicular to the guide rail base, and a rail waist connecting the guide rail base and the guide rail body; its characteristic is that the bottom surface of the guide rail base is provided with a V-shaped groove; the depth of the V-shaped groove is less than the thickness of the guide rail base.

[0005] Preferably, the rail waist is provided with rounded corners at the connections with the guide rail base and the guide rail body respectively.

[0006] Preferably, the guide rail base is provided with a plurality of mounting holes for fixing the guide rail base.

[0007] Preferably, the mounting holes are all countersunk holes.

[0008] Preferably, the width of the rail waist is smaller than the width of the guide rail body.

[0009] The beneficial effects of the present invention are as follows: by making the depth of the V-groove on the bottom surface of the guide rail base smaller than the thickness of the guide rail base, the thickness of the rail waist is increased, thereby preventing the rail waist from being deformed during the processing of the guide rail, which would cause the product to be scrapped. At the same time, the use strength of the guide rail can be improved and the weight of the guide rail can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Below we further explain the Y-shaped guide rail described in the utility model with reference to the accompanying drawings.

[0014] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0015] See attached Figure 1-2 As shown, the Y-shaped guide rail in this embodiment includes a guide rail base 1, a guide rail body 2 arranged perpendicular to the guide rail base 1, and a rail waist 3 connecting the guide rail base 1 and the guide rail body 2; it is characterized in that the bottom surface of the guide rail base 1 is provided with a V-shaped groove 101; the depth of the V-shaped groove 101 is less than the thickness of the guide rail base 1; by making the depth of the V-shaped groove 101 on the bottom surface of the guide rail base 1 less than the thickness of the guide rail base 1, the thickness of the rail waist 3 is increased, thereby preventing the rail waist 3 from being deformed during the processing of the guide rail, resulting in the scrapping of the product, and at the same time, the use strength of the guide rail can be improved and the weight of the guide rail can be reduced.

[0016] See attached Figure 1-2 As shown, the rail waist 3 is provided with fillets 4 at the connections with the guide rail base 1 and the guide rail body 2 respectively; the width of the rail waist 3 is smaller than the width of the guide rail body 2.

[0017] See attached Figure 1-2 As shown, the guide rail base 1 is provided with a plurality of mounting holes 102 for fixing the guide rail base 1; the mounting holes 102 are all countersunk holes; by utilizing the countersunk mounting holes 102, it is convenient to fix the guide rail base 1, and at the same time, it also reduces the height of the screws of the guide rail base 1 protruding from the guide rail base 1.

[0018] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the scope of protection of the present invention.
