Combined adjustable angle buffer bed

Abstract

This utility model discloses a combined adjustable angle cushioning bed, relating to the field of cushioning beds. It includes a base with a pre-formed cavity inside, and a cushioning bed base plate is installed inside the cavity. This utility model achieves positional movement by rotating a drive rod, which in turn rotates a linkage rod, causing the linkage rod to rotate within a threaded groove and a connecting groove. When the threaded rod moves away from the connecting groove, pulling the drive rod outward causes the first protrusion to move into the second cavity and not contact the linkage rod. This facilitates the outward pulling of the rubber sheet, allowing it to separate from the mounting frame for replacement. When installing a new rubber sheet, when the first protrusion matches the fitting groove, rotating the drive rod rotates the linkage rod, causing the threaded rod to rotate and move to match the connecting groove, thus completing the installation of the rubber sheet. The combined installation of the rubber sheet and the mounting frame allows for the replacement of damaged rubber sheets, thereby extending the service life of the cushioning bed.

Description

Technical Field

[0001] This utility model relates to the field of buffer beds, specifically to a combined adjustable angle buffer bed. Background Technology

[0002] A buffer bed is an important piece of equipment in mining and engineering projects. As the name suggests, a buffer bed can evenly distribute the weight of materials. It is mainly used to reduce the impact of materials falling on the conveyor belt, thereby protecting the conveyor belt and equipment and improving production efficiency and quality.

[0003] The existing cushioning beds still have the following problems when in use: The rubber sheet of the existing cushioning bed is installed as an integral part of the bed frame, which makes it inconvenient to replace the rubber sheet separately when it is damaged, resulting in poor overall cushioning bed performance.

[0004] Therefore, it is necessary to invent a modular adjustable angle buffer bed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a modular adjustable angle buffer bed to solve the problem mentioned in the background art that the rubber plate of the existing buffer bed is installed as an integral part of the bed body, which makes it inconvenient to replace the rubber plate separately when it is damaged, resulting in poor performance of the entire buffer bed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a combined adjustable angle buffer bed, including a base, the base having a pre-fabricated cavity, and a buffer bed base plate installed inside the cavity, and an installation frame installed on the top of the buffer bed base plate, with a rubber plate movably installed inside the installation frame via an installation component.

[0007] Preferably, the buffer bed base plate consists of three pieces. One buffer bed base plate is fixedly connected to the inner wall of the cavity, while the other two buffer bed base plates are symmetrically inclined with reference to the central axis of the base and are rotatably connected to the cavity. A rotating shaft is fixedly inserted inside the inclined buffer bed base plate, and the rotating shaft is rotatably connected to a pre-reserved rotating groove inside the base, which facilitates the rotation of the two inclined buffer bed base plates for angle adjustment.

[0008] Preferably, a second rotating shaft is arranged parallel to the side of the first rotating shaft. The second rotating shaft is also rotatably connected to the rotating groove reserved inside the base. A snap-fit ​​plate is fixedly fitted on the outer wall of the second rotating shaft, and the arc-shaped end of the snap-fit ​​plate matches the snap-fit ​​groove reserved inside the inclined buffer bed base plate. The matching of the snap-fit ​​plate and the snap-fit ​​groove limits the angle of the inclined buffer bed base plate.

[0009] Preferably, the mounting assembly includes an active rod that is rotatably connected to the mounting frame, and a protrusion fixedly connected to the outer wall of the end of the active rod matches a pre-reserved fitting groove inside the linkage rod that is rotatably connected inside the rubber plate. Furthermore, the threaded rod that is movably fitted outside the linkage rod is threadedly connected to the pre-reserved connecting groove inside the mounting frame and the threaded groove inside the rubber plate, and the linkage rod is rotatably connected to the threaded groove.

[0010] Preferably, the mounting assembly further includes a second protrusion fixedly connected to the end of the linkage rod, and the second protrusion, the linkage rod, and the movable groove reserved inside the threaded rod are movably connected. The movable groove is composed of a columnar groove and a strip groove connected to the columnar groove. The columnar groove and the linkage rod are in sliding fit, and the inner wall of the strip groove is in contact with the outer wall of the second protrusion to achieve sliding fit. Moving the drive rod drives the linkage rod to rotate, causing the threaded rod to rotate and the threaded groove to move and change position, thereby matching and connecting or separating with the connecting groove, so that the rubber plate can be replaced.

[0011] Preferably, the mounting assembly further includes two circular plates fitted with the outer ring of the active rod, and the two circular plates are elastically connected by a spring, and the two circular plates respectively abut against the two ends of the cavity reserved inside the mounting frame.

[0012] Preferably, one of the circular plates is fixedly sleeved on the outer wall of the active rod, and another circular plate is movably sleeved on the outer wall of the active rod. The crossbar fixedly connected to the center of the circular plate is slidably connected to the square groove reserved inside the active rod, making it easier to pull the active rod outward and rotate the active rod.

[0013] Preferably, the mounting assembly further includes a cavity two reserved inside the mounting frame, and the cavity two does not contact the active rod and the protrusion one fixedly connected to the end of the active rod, and the protrusion one can be completely moved into the cavity two, so that the rubber plate can be pulled out and replaced when the protrusion one moves into the cavity two and the threaded rod moves away from the connecting groove.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The present invention allows the rotating of the snap-fit ​​plate to match the arc-shaped end of the snap-fit ​​plate with any snap-fit ​​groove, thereby limiting the tilt angle of the inclined buffer bed base plate. At the same time, the snap-fit ​​plate can also provide support for the inclined buffer bed base plate, thus facilitating the use of the buffer bed.

[0016] 2. By rotating the drive rod, the linkage rod rotates, causing the threaded rod to rotate within the threaded groove and connecting groove, thus moving its position. When the threaded rod moves away from the connecting groove, pulling the drive rod outward causes the first protrusion to move into the second cavity and not contact the linkage rod. At this point, it is convenient to pull the rubber sheet outward, allowing the rubber sheet to separate from the mounting frame for replacement. When installing a new rubber sheet, when the first protrusion matches the fitting groove, rotating the drive rod rotates, causing the linkage rod to rotate. At this point, the threaded rod rotates and moves to match the connecting groove, thus completing the installation of the rubber sheet. The combined installation of the rubber sheet and the mounting frame allows for the replacement of damaged rubber sheets, thereby extending the service life of the buffer bed.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-6 The present invention relates to a modular adjustable angle cushioning bed, comprising a base 1, a cavity 2 prefabricated inside the base 1, a cushioning bed base plate 3 installed inside the cavity 2, and an installation frame 4 installed on top of the cushioning bed base plate 3. A rubber plate 5 is movably installed inside the installation frame 4 via an installation assembly 10.

[0028] There are three buffer bed base plates 3 in total. One buffer bed base plate 3 is fixedly connected to the inner wall of the cavity 2. The other two buffer bed base plates 3 are symmetrically inclined with reference to the central axis of the base 1 and are rotatably connected to the cavity 2. A rotating shaft 6 is fixedly inserted inside the inclined buffer bed base plate 3 and is rotatably connected to the rotating groove reserved inside the base 1, so that the two inclined buffer bed base plates 3 can be rotated to adjust the angle.

[0029] A second rotating shaft 7 is arranged parallel to the side of the first rotating shaft 6. The second rotating shaft 7 is also rotatably connected to the rotating groove reserved inside the base 1. A snap-fit ​​plate 8 is fixedly fitted on the outer wall of the second rotating shaft 7. The arc-shaped end of the snap-fit ​​plate 8 matches the snap-fit ​​groove 9 reserved inside the inclined buffer bed base plate 3. The matching of the snap-fit ​​plate 8 and the snap-fit ​​groove 9 limits the angle of the inclined buffer bed base plate 3.

[0030] When in use, the snap-fit ​​plate 8 is rotated so that the arc-shaped end of the snap-fit ​​plate 8 matches any snap-fit ​​groove 9, thereby limiting the tilt angle of the inclined buffer bed base plate 3. At the same time, the snap-fit ​​plate 8 can also provide support for the inclined buffer bed base plate 3, thus facilitating the use of the buffer bed.

[0031] The mounting assembly 10 includes an active rod 101 that is rotatably connected to the mounting frame 4. A protrusion 102 fixedly connected to the outer wall of the end of the active rod 101 matches the mating groove 103 reserved inside the linkage rod 104 that is rotatably connected inside the rubber plate 5. The threaded rod 106 that is movably fitted outside the linkage rod 104 is threadedly connected to the connecting groove 108 reserved inside the mounting frame 4 and the threaded groove inside the rubber plate 5. The linkage rod 104 is rotatably connected to the threaded groove.

[0032] The mounting assembly 10 also includes a second protrusion 105 fixedly connected to the end of the linkage rod 104. The second protrusion 105 and the linkage rod 104 are movably connected to the movable groove 107 reserved inside the threaded rod 106. The movable groove 107 is composed of a columnar groove and a strip groove connected to the columnar groove. The columnar groove and the linkage rod 104 are in sliding fit, and the inner wall of the strip groove is in contact with the outer wall of the second protrusion 105 to achieve sliding fit.

[0033] The active lever 101 is turned to drive the linkage lever 104 to rotate, which causes the threaded rod 106 to rotate and move and change position with the threaded groove, thereby matching and connecting or separating with the connecting groove 108, making the rubber plate 5 replaceable.

[0034] The mounting assembly 10 also includes two circular plates 109 that are fitted around the outer ring of the active rod 101. The two circular plates 109 are elastically connected by a spring 112. The two circular plates 109 abut against the two ends of the cavity 113 reserved inside the mounting frame 4. One circular plate 109 is fixedly fitted onto the outer wall of the active rod 101, and the other circular plate 109 is movably fitted onto the outer wall of the active rod 101. The crossbar 110 fixedly connected to the center of the circular plate 109 is slidably connected to the square groove 111 reserved inside the active rod 101.

[0035] This makes it smoother to pull the active rod 101 outward and rotate the active rod 101 by means of a dial plate fixedly connected to the end of the active rod 101, and the force applied by the spring 112 to the active rod 101 makes it easier for the protrusion 102 to match the fitting groove 103.

[0036] The mounting assembly 10 also includes a cavity 114 reserved inside the mounting frame 4. The cavity 114 does not contact the drive rod 101 and the protrusion 102 fixedly connected to the end of the drive rod 101. The protrusion 102 can be completely moved into the cavity 114. When the protrusion 102 moves into the cavity 114 and the threaded rod 106 moves away from the connecting groove 108, the rubber plate 5 can be pulled out and replaced.

[0037] When the rubber plate 5 needs to be replaced during use, rotating the drive rod 101 rotates the linkage rod 104, causing the linkage rod 104 to drive the threaded rod 106 to rotate within the threaded groove and connecting groove 108, thus achieving positional movement. The pre-reserved movable groove 107 inside the threaded rod 106 ensures that the linkage rod 104 can still adjust the rotation of the threaded rod 106 when it moves. When the threaded rod 106 moves away from the connecting groove 108, pulling the drive rod 101 outward causes the protrusion 102 to move into the cavity 114 and not contact the linkage rod 104. At this time, it is convenient to pull the rubber plate 5 outward to separate the rubber plate 5 from the mounting frame 4 for replacement. When installing the new rubber plate 5... Pulling the active rod 101 outward causes the protrusion 102 to move into the cavity 114, matching the new rubber plate 5 with the mounting frame 4. The force applied by the spring 112 causes the active rod 101 and the protrusion 102 to abut against the end of the linkage rod 104 with the fitting groove 103. Rotating the active rod 101, when the protrusion 102 and the fitting groove 103 can match, the spring 112 applies a force to match the protrusion 102 and the active rod 101 with the fitting groove 103, and then the active rod 101 can be turned to rotate, driving the linkage rod 104 to rotate. At this time, the threaded rod 106 rotates and moves to match the connecting groove 108, thus completing the installation of the rubber plate 5.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
