Description

Technical Field

[0001] The utility model belongs to the technical field of guide rails, and particularly relates to a dust-proof sealing structure for guide rails. Background Technique

[0002] The guide rail is an important part of mechanical transmission components and is widely used in fields such as aviation manufacturing, machining, and automation equipment. In related technologies, the guide rail is assembled by a slide rail, a slider, balls, a ball retainer, a ball return groove, etc. The main principle is to make the ball column move in a cycle through structures such as the ball return groove and the ball retainer, so as to realize the low-friction linear motion of the slider on the slide rail. During the operation of the guide rail, it will be interfered by a large amount of dust, sand and other impurities in the environment, thus affecting its stability and accuracy. Therefore, when installing the guide rail, due to improper operation, it is easy to cause the dust-proof cap of the guide rail to be installed in place, resulting in the dust-proof cap being tilted, sunken or not installed in place, thus affecting the normal use of the guide rail. Therefore, a dust-proof sealing structure for the guide rail is needed to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a dust-proof sealing structure for a guide rail, which limits and fixes the cylinder and the round cover through a limiting member, makes the round cover fit in the annular groove, and the upper side of the round cover is in the same plane as the upper side of the guide rail body, ensuring the flatness of the upper side of the guide rail and at the same time ensuring the sealing performance of the guide rail, and ensuring the normal use of the guide rail.

[0017] In order to enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be further described below with reference to the drawings and embodiments.

[0018] As Figures 1-3 shown, a dust-proof and sealing structure of a guide rail of the present invention includes a guide rail body 1, a mounting hole 10 is opened on the upper side of the guide rail body 1, a cylinder 11 matching the mounting hole 10 is installed on the upper side of the guide rail body 1, an annular groove 12 matching the mounting hole 10 is opened on the upper side of the guide rail body 1, a round cover 13 matching the annular groove 12 is fixedly arranged on the upper side of the cylinder 11, and a limiting piece is arranged between the cylinder 11 and the conveying guide rail body 1;

[0019] When the utility model is in use, first install the guide rail body 1 at a designated position, then directly insert the cylinder 11 into the installation hole 10. After the user limits and fixes the cylinder 11 through the limiting member, the round cover 13 is attached to the annular groove 12 to cover the installation hole 10, so that a smooth plane is formed between the round cover 13 and the upper side of the guide rail body 1;

[0020] The utility model limits and fixes the cylinder and the round cover through the limiting member, so that the round cover fits in the annular groove, and the upper side of the round cover is in the same plane as the upper side of the guide rail body, ensuring the flatness of the upper side of the guide rail and at the same time ensuring the sealing performance of the guide rail, and ensuring the normal use of the guide rail.

[0021] The limiting member includes a plurality of vertical grooves 14 opened on the side wall of the installation hole 10. The plurality of vertical grooves 14 are arranged in a circumferential manner. A horizontal groove 15 is opened on the lower side of each of the plurality of vertical grooves 14. A clamping groove 16 is opened on one side of each of the plurality of horizontal grooves 15 away from the vertical groove 14. A plurality of clamping blocks 17 matched with the clamping grooves 16 are fixedly arranged on the side wall of the cylinder 11. A plurality of vertical blocks 18 matched with the vertical grooves 14 are fixedly arranged on the side wall of the cylinder 11;

[0022] When the utility model is installed, the user first aligns the plurality of clamping blocks 17 with the vertical grooves 14, then presses the cylinder 11 into the installation hole 10, so that the plurality of clamping blocks 17 are inserted into the vertical grooves 14. After the plurality of clamping blocks 17 abut against the lower side wall of the horizontal groove 15, the user rotates the cylinder 11, and the cylinder 11 drives the clamping blocks 17 to rotate synchronously. After the clamping blocks 17 abut against the side wall of the horizontal groove 15 and at the same time the vertical blocks 18 are located above the vertical grooves 14, the user directly presses the round cover 13 into the installation hole 10. The round cover 13 drives the cylinder 11 to move into the installation hole 19, the clamping blocks 17 are clamped into the clamping grooves 16, and at the same time the vertical blocks 18 are also inserted into the vertical grooves 14, thereby limiting and fixing the cylinder 11 and the round cover 13, preventing the cylinder 11 and the round cover 13 from rotating independently, and ensuring the normal use of the guide rail body 1.

[0023] A plurality of elastic blocks 20 distributed in a circumferential manner are fixedly arranged on the lower side of the cylinder 11. A limiting block 21 is fixedly arranged on one side of each of the plurality of elastic blocks 20 close to the side wall of the installation hole 10. An annular limiting groove 22 matched with the plurality of limiting blocks 21 is opened on the side wall of the installation hole 10;

[0024] When the present utility model is in use, when installing the cylinder 11, when the user inserts the cylinder 11 into the installation hole 10, the user first presses several elastic blocks 20 towards the middle, so that several limiting blocks 21 are inserted into the installation hole 10 at the same time. When the cylinder 11 slides towards the installation hole 10, it drives several elastic blocks 20 and several limiting blocks 21 to move synchronously. After the clamping block 17 and the vertical block 18 are inserted into the clamping groove 16 and the vertical groove 14 respectively, several limiting blocks 21 are clamped into the annular limiting groove 22 under the elastic action of the elastic blocks 20, to limit and fix the cylinder 11 and the round cover 13, prevent the cylinder 11 and the round cover 13 from moving up and down independently, ensure that the round cover 13 always covers the annular groove 12, ensure the sealing performance of the guide rail body 1, and ensure the normal use of the guide rail body 1.

[0025] The height of the clamping block 17 is equal to the height of the horizontal groove 15, and the width of the clamping block 17 is equal to the width of the vertical groove 14; ensure that the clamping block 17 can slide smoothly in the horizontal groove 15 and the vertical groove 14, and ensure the smooth installation of the cylinder 11 and the round cover 13.

[0026] The distance between the clamping block 17 and the adjacent vertical block 18 is equal to the length of the horizontal groove 15; ensure that when the cylinder 11 is rotated, the clamping block 17 and the vertical block 18 are accurately located above the clamping groove 16 and the vertical groove 14, and ensure the installation of the cylinder 11 and the round cover 13.

[0027] The above embodiments only exemplarily illustrate the principle and its effects of the present utility model, rather than being used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model.
