Description

Technical Field

[0001] The utility model belongs to the technical field of automatic doors, and in particular relates to a noise reduction guide rail structure and an automatic door. Background Art

[0002] A guide rail is a device with grooves or ridges made of metal or other materials that can bear, fix, guide and reduce friction of moving devices or equipment. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine parts, special equipment, instruments, etc. Guide rails are also called slide rails, linear guides, and linear slides. They are used in linear reciprocating motion occasions and have higher rated loads than linear bearings. At the same time, they can bear a certain torque and can achieve high-precision linear motion under high load conditions.

[0003] For example, the Chinese patent document with publication number CN203978107U discloses a composite guide rail for an automatic door machine, comprising a guide rail, a bracket, two fixing parts and a buffer part, the bracket is provided with two mounting grooves, the buffer part is placed in parallel in the mounting groove of the bracket, and then the guide rail is movably mounted on the mounting groove of the bracket through two fixing parts, the two fixing parts are respectively sleeved on the two ends of the bracket and the guide rail, and the guide rail is positioned parallel to the bracket; each fixing part comprises a fixing element and a fastening element, the fixing element is sleeved on the ends of the bracket and the guide rail, the fastening element is movably mounted on the bracket, and the guide rail is movably mounted in parallel on the mounting groove of the bracket through the cooperation of the fixing element and the fastening element.

[0004] In the technical solution of the above patent document, due to the lack of structural design of the guide rails, brackets, buffers and fixings, integration cannot be achieved. Therefore, these components are separated when leaving the factory and during transportation. After receiving these components, the on-site automatic door construction personnel assemble them together, and fix them by tightly fitting the guide rails, buffers and brackets with the fixings, and then further tighten the guide rails and buffers by relying on gravity and the pressure of the pulley after installing the pulley. This method requires close matching of the dimensions between the guide rails, fixings, buffers and brackets, and also increases the difficulty of the construction personnel's work. In addition, since the guide rails are long and thin, it is very easy to cause the track to bend and deform during transportation, making the track unusable. Utility Model Content

[0005] The utility model aims to provide a noise-reducing guide rail structure to solve the problems that the existing guide rails, buffers and brackets have high dimensional precision, which makes them difficult to install, and the guide rails are easily bent and deformed when transported alone, making them unusable.

[0006] To achieve the above-mentioned purpose, an embodiment of the utility model provides a noise reduction guide rail structure, including a guide rail mounting body, a buffer component and a track, the guide rail mounting body is provided with a mounting surface, the mounting surface has a limiting side wall extending upward, the two limiting side walls form a limiting groove, the buffer component is laid in the limiting groove, the track is arranged in the limiting groove, steps are provided on both sides of the track, the upper end of the limiting side wall is bent inwardly to form a limiting portion limited to the top side of the step.

[0007] Furthermore, both sides of the buffer component are wrapped and folded upward to form an upper buffer portion wrapped around the top side of the step position, and the limiting portion presses the upper buffer portion at the step position.

[0008] Furthermore, a hanging portion extends from one side of the guide rail mounting body, and the mounting surface is arranged on the top side of the hanging portion.

[0009] Furthermore, the buffer component is a soft rubber pad.

[0010] The above one or more technical solutions in the noise reduction guide rail structure provided by the embodiment of the utility model have at least the following technical effects:

[0011] Since the two limiting side walls extending upward from the installation surface of the guide rail installation body form a limiting groove, the buffer is laid directly in the limiting groove from above the limiting groove, and the track is arranged in the limiting groove and placed on the buffer. The assembly steps are simple, and the preliminary matching of the guide rail installation body, the buffer and the track is achieved. In addition, there are steps on both sides of the track, and the upper ends of the limiting side walls are bent inward to form a limiting portion limited to the top side of the track step, so that the track and the buffer fit tightly and are fixed in the limiting groove. The difficulty of installing the track, the buffer and the guide rail installation body is greatly reduced. The guide rail installation body, the buffer and the track are integrated, so that the track is embedded in the guide rail installation body and the buffer to obtain structural protection, and the risk of bending and deformation of the track during transportation is reduced. At the same time, the on-site splicing process of the construction personnel is reduced, the construction difficulty of the construction personnel is reduced, and the construction quality of the automatic door track is guaranteed.

[0012] An automatic door comprises a noise reduction guide rail structure and a sliding door. A pulley assembly is provided on the top side of the sliding door, and the pulley assembly is rollingly supported on the track.

[0013] The above one or more technical solutions in the automatic door provided by the embodiment of the utility model have at least the following technical effects:

In addition, according to the size of the automatic door fixing seat, the two ends of the noise reduction rail structure are cut as a whole, and then the noise reduction rail structure is set on the automatic door fixing seat. It does not require high-precision dimensional processing to meet the installation requirements of automatic doors of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figures 1 to 5The noise reduction guide rail structure 100 in this embodiment includes a guide rail installation body 110, a buffer member 120 and a track 130. The guide rail installation body 110 is provided with a mounting surface 111. The mounting surface 111 extends upward with a limiting side wall 112. The two limiting side walls 112 form a limiting groove 113. The buffer member 120 is laid in the limiting groove 113. The track 130 is arranged in the limiting groove 113. Step positions 131 are provided on both sides of the track 130. The upper end of the limiting side wall 112 is bent inward to form a limiting portion 114 limited to the top side of the step 131.
