Abstract
Description
Technical Field
[0001] This utility model relates to the field of door slide rail technology, and more specifically, to a manual door slide rail mechanism. Background Technology
[0002] A manual door sliding mechanism is a device used to support the opening and closing of a manually operated door. The sliding rail is the key component of the entire mechanism and is usually made of metal, such as aluminum alloy or stainless steel. It has a specific shape and size, with U-shaped rails and linear rails being the most common. U-shaped rails can limit the movement of the door on both sides, making the door more stable during sliding; linear rails have a simple structure and are easy to install. For example, some wardrobe manual sliding doors often use linear rails.
[0003] In most door sliding mechanisms, there is some space between the pulley and the inner wall of the track during the sliding process. If the manual operation is not done properly, the pulley can easily wobble and vibrate, thus generating noise. In addition, these gaps can also cause poor contact between the pulley and the door sliding mechanism during the sliding process, which will affect the smoothness of the door sliding mechanism and the user experience. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution;
[0006] A manual door sliding mechanism includes a fixed track. A sliding track profile is provided on the front of the fixed track. Locking plate reinforcing plates are fixedly installed on both sides of the sliding track profile. Locking plates are fixedly installed on both locking plate reinforcing plates by bolts. Locking block supports are fixedly installed on both sides of the fixed track by bolts. Locking blocks are installed on both locking block supports. The two locking blocks are respectively matched with two locking blocks. Two upper guide wheel mechanisms and two lower guide wheel mechanisms are installed on the back of the sliding track profile. The upper guide wheel mechanisms and lower guide wheel mechanisms are located inside the fixed track and contact the inner wall of the fixed track.
[0007] As a further description of the above technical solution:
[0008] The upper guide wheel mechanism includes a first eccentric shaft mounted on the slide rail profile, a first bearing fixedly mounted on the first eccentric shaft, a cam fixedly mounted on the outer side of the first bearing, and the top of the cam contacting the inner top wall of the fixed track.
[0009] As a further description of the above technical solution:
[0010] The lower guide wheel mechanism includes a second eccentric shaft mounted on the slide rail profile, a second bearing fixedly mounted on the second eccentric shaft, and a U-shaped wheel fixedly mounted on the outer side of the second bearing, the bottom of the U-shaped wheel contacting the inner bottom wall of the fixed track.
[0011] As a further description of the above technical solution:
[0012] The inner top wall of the fixed track is concave, and the concave shape matches the shape of the cam. The inner bottom wall of the fixed track is convex, and the convex shape matches the concave shape of the U-shaped wheel.
[0013] As a further description of the above technical solution:
[0014] The bottom of the slide rail profile has countersunk screw holes.
[0015] As a further description of the above technical solution:
[0016] Both sides of the slide rail profile are fixedly installed with buffer block supports by screws, and each of the two buffer block supports is fixedly installed with rubber-coated bolts.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;
[0026] Please see Figures 1-4 In this utility model, a manual door slide rail mechanism includes a fixed track 1. A slide rail profile 2 is provided on the front of the fixed track 1. Locking plate reinforcing plates 3 are fixedly installed on both sides of the slide rail profile 2. Locking plates 4 are fixedly installed on both locking plate reinforcing plates 3 by bolts. Locking block supports 5 are fixedly installed on both sides of the fixed track 1 by bolts. Locking blocks 6 are installed on both locking block supports 5. The two locking blocks 6 are respectively matched with the two locking blocks 6. Two upper guide wheel mechanisms 7 and two lower guide wheel mechanisms 8 are installed on the back of the slide rail profile 2. The upper guide wheel mechanisms 7 and lower guide wheel mechanisms 8 are located inside the fixed track 1 and in contact with the inner wall of the fixed track 1.
[0027] In this utility model, by setting two upper guide wheel mechanisms 7 and two lower guide wheel mechanisms 8 on the back of the slide rail profile 2, and by cooperating with the locking blocks 6 on the locking block supports 5 on both sides and the locking pieces 4 on the slide rail profile 2, the movement of the slide rail profile 2 can be restricted to a certain extent when it moves to both ends of the fixed track 1. It can disengage when manually applied, which is convenient for operation. The two upper guide wheel mechanisms 7 and two lower guide wheel mechanisms 8 on the slide rail profile 2 are kept in contact with the top and bottom walls of the inner wall of the fixed track 1 to prevent the slide rail profile 2 from shaking when sliding. The upper guide wheel mechanisms 7 and lower guide wheel mechanisms 8 fill the sliding gap of the fixed track 1 to prevent vibration during the sliding process, and ensure that the slide rail mechanism does not vibrate too much when operating, thus ensuring the quiet operation of the slide rail mechanism.
[0028] Please see Figure 1 and Figure 3 The upper guide wheel mechanism 7 includes a first eccentric shaft 71 mounted on the slide rail profile 2, a first bearing 72 fixedly mounted on the first eccentric shaft 71, a cam 73 fixedly mounted on the outer side of the first bearing 72, and the top of the cam 73 contacting the inner top wall of the fixed track 1.
[0029] In this utility model, the cam 73 is conveniently mounted on the first eccentric shaft 71 through the first bearing 72, which facilitates the slide rail profile 2 to slide on the fixed track 1 through the upper guide wheel mechanism 7.
[0030] Please see Figure 1 and Figure 4 The lower guide wheel mechanism 8 includes a second eccentric shaft 81 mounted on the slide rail profile 2. A second bearing 82 is fixedly mounted on the second eccentric shaft 81. A U-shaped wheel 83 is fixedly mounted on the outer side of the second bearing 82. The bottom of the U-shaped wheel 83 contacts the inner bottom wall of the fixed track 1.
[0031] In this utility model, the U-shaped wheel 83 is conveniently installed on the second eccentric shaft 81 through the second bearing 82, and in conjunction with the guide wheel mechanism 7, the slide rail profile 2 slides stably on the fixed track 1.
[0032] Please see Figure 1 , 3 4, wherein: the inner top wall of the fixed track 1 is concave, the concave shape matches the shape of the cam 73, and the inner bottom wall of the fixed track 1 is convex, the convex shape matches the concave shape of the U-shaped wheel 83.
[0033] In this invention, the irregularly shaped cam 73 and U-shaped wheel 83 can improve their fit with the inner wall of the fixed track 1 and prevent the cam 73 and U-shaped wheel 83 from falling off the fixed track 1, further ensuring the stability of the cam 73 and U-shaped wheel 83 when rolling against the inner wall of the fixed track 1 and improving the noise reduction effect.
[0034] Please see Figure 2 Among them, the bottom of the slide rail profile 2 is provided with countersunk screw holes 9.
[0035] In this utility model, the countersunk screw hole 9 facilitates the placement of countersunk screws, connecting the slide rail profile 2 with the door and other structures for use as a guide rail mechanism.
[0036] Please see Figure 1 Among them, buffer block supports 10 are fixedly installed on both the left and right sides of the slide rail profile 2 by screws, and rubber-coated bolts 11 are fixedly installed on both buffer block supports 10.
[0037] In this utility model, the rubber-coated bolts 11 on the buffer block support 10 can play a buffering role when the slide rail profile 2 slides to the end.
[0038] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
