Description

Technical Field

[0001] The utility model relates to the technical field of rails, in particular to a walking guide rail structure which is easy to install. Background Art

[0002] A walking guide is a device, usually made of metal or other materials, with longitudinal grooves or ridges, used to bear, fix, guide and reduce friction of moving devices or equipment; this device is also called a slide rail, linear guide or linear slide, and is particularly suitable for occasions requiring linear reciprocating motion; compared with linear bearings, walking guides can carry higher rated loads and can withstand a certain torque, so they can achieve high-precision linear motion under high load conditions. They are widely used in industrial production, elevators, pulleys and other fields. When installing linear guides, a gap of 0.03-0.05mm needs to be reserved at the interface between the guide rails to prevent axial elongation caused by thermal expansion of the guide rails. Because the gap is too small, installers are usually required to prepare feeler gauges in advance during installation, so that they can use the feeler gauge gap for detection during installation to avoid excessive gaps that affect the normal walking of the slider at the guide rail joint, and at the same time avoid too small gaps. During use, the guide rails undergo thermal expansion, resulting in axial elongation, affecting the walking accuracy of the slider on the guide rail.

[0003] For example, the patent with announcement number CN218894881U discloses a linear guide rail, including a slide rail, a slider and a dustproof device. The slide rail extends along a first direction, and the slider is movably mounted on the slide rail. Along the first direction, the slider includes a first end cap and a second end cap that are arranged opposite to each other, and the dustproof device includes a first dustproof member and a second dustproof member connected to the first end cap. Along the second direction, the first dustproof member is in flexible contact with one side of the slide rail, and the second direction is perpendicular to the first direction. Along the second direction, the second dustproof member is in flexible contact with the side of the slide rail that is away from the first dustproof member. Along the second direction, at least one of the first dustproof member and the second dustproof member can adjust the connection position with the first end cap to adjust the distance between the first dustproof member and the second dustproof member in the second direction, thereby reducing the risk of reduced dustproof effect due to wear of the first dustproof member and the second dustproof member, and also allowing the first dustproof member and the second dustproof member to be suitable for sliders of different sizes.

[0004] However, the walking guide rail in the above technology still has the following problems:

[0005] Although the above technology can adapt to the use of sliders of different sizes through the detachable dustproof parts, since a gap is reserved between the guide rails during installation to prevent axial elongation caused by thermal expansion, some dust may fall into the tiny gap at the joint of the guide rails during use. When the guide rails expand thermally, the dust in the gap will squeeze the joint, causing axial displacement of the two spliced ​​guide rails, and then causing displacement of the guide rail joint, affecting the normal movement of the slider at the guide rail joint, and even causing jamming. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a walking guide rail structure that is easy to install, such as: performing dust-proof treatment on the guide rail joint gap to prevent dust from falling into the joint gap, ensuring that axial elongation does not occur when the guide rail expands thermally, and ensuring the stability of the slider walking on the guide rail.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a walking guide rail structure that is easy to install, comprising two guide rail bodies, the upper surface of the same end of the two guide rail bodies is penetrated with an installation groove, the middle position of the other end of the two guide rail bodies is fixedly connected with a reserved piece, the other sides of the two reserved pieces are fixedly connected with a mounting block, the mounting blocks are slidably connected to adjacent mounting grooves, and the adjacent ends of the two guide rail bodies are connected to two dust rings, and the two dust rings are respectively located on both sides of the reserved piece.

[0008] Furthermore, two sides of the reserved piece are slidably connected to two sides of an adjacent mounting groove, and the mounting block can move laterally in the mounting groove by a distance not less than the thickness of the reserved piece.

[0009] Furthermore, a communicating blocking groove is provided at the top of the installation groove, a blocking piece is fixedly connected to the top of the installation block, and the blocking piece is slidably connected to the blocking groove.

[0010] Furthermore, a cavity is provided inside the dustproof ring.

[0011] Furthermore, the blocking piece is a rubber piece.

[0012] Furthermore, the thickness of the reserved sheet is between 0.03 and 0.05 mm.

[0013] Furthermore, the thickness of the dustproof ring is equal to the thickness of the reserved sheet.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] This easy-to-install walking guide rail structure can achieve quick connection and positioning between the two guide rail bodies through the connection between the mounting block and the mounting groove, reducing the positioning and alignment operation time during guide rail installation. At the same time, a reserved piece is used to leave a splicing gap between the two guide rail bodies to avoid axial elongation caused by thermal expansion of the guide rail. At the same time, a dust ring is used to seal the reserved splicing gap to prevent external dust from entering the splicing gap, causing the splicing gap to be blocked, and then causing axial elongation when the guide rail expands thermally.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figure 1 - Figure 6 A walking guide rail structure that is easy to install includes two guide rail bodies 1. The upper surfaces of the same ends of the two guide rail bodies 1 are penetrated with installation grooves 101. The middle positions of the other ends of the two guide rail bodies 1 are fixedly connected with reserved pieces 2. The other sides of the two reserved pieces 2 are fixedly connected with installation blocks 3. The installation blocks 3 are slidably connected to adjacent installation grooves 101. Two dust rings 4 are connected to the adjacent ends of the two guide rail bodies 1, and the two dust rings 4 are respectively located on both sides of the reserved pieces 2.

[0025] like Figure 1 - Figure 6 As shown, a walking guide rail structure that is easy to install in the utility model is similar to the existing walking guide rail structure, such as a linear guide rail disclosed in the patent with announcement number CN218894881U. The main improvement of the utility model is to achieve rapid installation between the guide rails and improve the use effect after installation. Figures 1 to 6 As shown, when the walking guide structure that is easy to install in the utility model is used, the mounting block 3 at the end of the guide rail body 1 is close to the mounting groove 101 at the end of another guide rail body 1 to be spliced, and then the mounting block 3 is inserted into the mounting groove 101. At this time, the reserved piece 2 can leave a certain splicing gap between the two mutually spliced ​​guide rail bodies 1, and the dust ring 4 can block the reserved splicing gap, so as to prevent external dust from entering the splicing gap during use, and always keep the splicing gap free of debris. When the guide rail body 1 undergoes thermal expansion and produces a certain axial elongation, the guide rail body 1 The end portion is extended and close to the end portion of another adjacent guide rail body 1. Due to the existence of the splicing gap, deformation of the track formed by splicing can be avoided. When the end portion of the guide rail body 1 is extended due to thermal expansion, the reserved piece 2 and the mounting block 3 will slide back and forth in the mounting groove 101 without affecting the thermal expansion and elongation of the guide rail body 1. At the same time, the end portion of the guide rail body 1 will squeeze the dust ring 4 to flatten it. It should be particularly noted that after the dust ring 4 is flattened by the thermal expansion of the guide rail body 1, the dust ring 4 can be restored to its original state while waiting for the guide rail body 1 to cool and recover, thereby always sealing the splicing gap.

[0026] like Figure 1 - Figure 6 As shown, the two sides of the reserved sheet 2 are slidably connected to the two sides of the adjacent mounting groove 101, and the mounting block 3 can move laterally in the mounting groove 101 by a distance not less than the thickness of the reserved sheet 2. When the guide rail body 1 undergoes axial expansion due to thermal expansion, the reserved sheet 2 and the mounting block 3 will slide axially in the mounting groove 101. At this time, the axial sliding distance of the mounting block 3 in the mounting groove 101 needs to ensure that the reserved sheet 2 completely enters the mounting groove 101, avoiding the reserved sheet 2 and the mounting block 3 from being squeezed against the inner wall of the mounting groove 101, so that the reserved splicing gap can meet the distance of axial expansion due to thermal expansion.

[0027] like Figure 1 - Figure 6As shown, a connected blocking groove 102 is provided at the top of the installation groove 101, and a blocking piece 5 is fixedly connected to the top of the installation block 3, and the blocking piece 5 is slidably connected to the blocking groove 102. Since the installation block 3 needs to maintain a certain sliding distance in the installation groove 101, there must be a certain gap in the installation groove 101. At this time, the upper part of the installation groove 101 can be blocked by the blocking piece 5, so as to prevent dust from entering the installation groove 101 and affecting the axial extension of the guide rail body 1. At the same time, through the design of the blocking groove 102, the blocking piece 5 is located in the blocking groove 102, so as to prevent the blocking piece 5 from obstructing the sliding block sliding on the guide rail body 1.

[0028] like Figure 3 As shown, a cavity 401 is provided inside the dust ring 4. The cavity 401 is provided inside the dust ring 4 to further reduce the thickness of the dust ring 4 entity, so that the dust ring 4 can become thinner when compressed, and when the dust ring 4 is flattened, the splicing gap can be more compensated.

[0029] like Figure 1 - Figure 6 As shown, the blocking piece 5 is a rubber piece. When the rubber piece is used to make the blocking piece 5, when the mounting block 3 moves and slides in the mounting groove 101, the blocking piece 5 can always keep blocking the mounting groove 101 through the characteristics of extrusion deformation.

[0030] like Figure 1 - Figure 6 As shown, the thickness of the reserved sheet 2 is between 0.03 and 0.05 mm. The thickness of the reserved sheet 2 is designed to be between 0.03 and 0.05 mm to meet the axial elongation distance that may occur when the guide rail body 1 is thermally expanded. The thickness of the reserved sheet 2 can also be adjusted according to the thermal expansion deformation amplitude of different guide rail body 1 materials to meet the axial deformation compensation generated by different materials during thermal expansion.

[0031] like Figure 1 - Figure 6 As shown, the thickness of the dust ring 4 is equal to the thickness of the reserved sheet 2. When the guide rail body 1 does not undergo thermal expansion, the two guide rail bodies 1 are separated by the dust ring 4, thereby leaving a splicing gap in the middle. At this time, the thickness of the reserved sheet 2 is equal to that of the dust ring 4, which can prevent the dust ring 4 from hindering the splicing operation when the two guide rail bodies 1 are spliced ​​together.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
