Description

Technical Field

[0001] This utility model relates to the field of writing board technology, specifically to a push-pull writing board combined slide. Background Technology

[0002] Writing boards are a common tool in teaching. The most common type of writing board is flat and fixed. With the development of technology, multimedia interactive devices such as slide projectors, projection screens, electronic whiteboards, electronic whiteboard all-in-one machines, and touch TV all-in-one machines are used together, which has led to the development of modular sliding writing boards. The movement and transformation of modular sliding writing boards cannot be separated from modular tracks.

[0003] In existing technologies, the combined track is in an open state during use, and a large amount of dust or particulate impurities accumulate inside the track during use. This dust will cause the writing board to gradually become stiff when pushed and pulled, and will also cause wear and tear on the writing board and the track itself during sliding.

[0026] Figures 1-6In one embodiment of this utility model, a push-pull writing board combination slide includes a slide rail 1 and a writing board 2 slidably mounted above the slide rail 1. Two sets of symmetrically distributed mounting boxes 3 are provided on both sides of the slide rail 1. A cleaning seat 4 is fixedly installed between the mounting box 3 and the slide rail 1. A dustproof mechanism 5 is provided inside the mounting box 3, and a cleaning mechanism 7 is provided inside the cleaning seat 4. The dustproof mechanism 5 includes a winding rod 501 rotatably mounted inside the mounting box 3 and a dustproof belt 503. The dustproof belt 503 is slidably connected to the slide rail 1 and is wound around the winding rod 501. Two sets of symmetrically distributed coil springs 502 are provided on the winding rod 501, and the inner and outer ends of the coil springs 502 are fixedly connected to the winding rod 501 and the mounting box 3, respectively. A pull rod 504 is fixedly installed at the end of the dustproof belt 503 away from the winding rod 501. Two sets of symmetrically distributed fixing rods 505 are provided inside the slide rail 1. Furthermore, the pull rod 504 is slidably sleeved with two sets of fixed rods 505 respectively. A first spring 506 is sleeved on the fixed rod 505. The two ends of the first spring 506 are fixedly connected to the pull rod 504 and the slide rail 1 respectively. Positioning mechanisms 6 for fixing the pull rod 504 are installed on both sides of the writing board 2. The cleaning mechanism 7 includes a cleaning roller 701 rotatably installed in the cleaning seat 4. The cleaning roller 701 is in contact with the upper surface of the dustproof belt 503. The positioning mechanism 6 is used to fix the pull rod 504 on the dustproof belt 503 on both sides of the slide rail 1 to the writing board 2, so that the dustproof belt 503 covers the slide rail 1. During the use of the writing board 2 and the slide rail 1, dust is prevented from accumulating in the slide rail 1, which would eventually affect the normal use of the combined slide rail. At the same time, the cleaning mechanism 7 is used to clean the dust adhering to the surface of the dustproof belt 503 during use.

[0027] In this embodiment, reference Figure 3 and Figure 4 , Figure 5As shown, a second gear 702 is sleeved on the cleaning roller 701, a second rack 703 is slidably installed inside the cleaning seat 4, and the second rack 703 meshes with the second gear 702. A slide rod 704 is fixedly installed inside the cleaning seat 4, and a cleaning brush 707 is slidably installed on the cleaning seat 4, with the cleaning brush 707 in contact with the cleaning roller 701. A cam 706 is rotatably installed on the cleaning seat 4, and the cleaning brush 707 is slidably sleeved with the slide rod 704. Two sets of symmetrically distributed third springs 705 are sleeved on the slide rod 704, and the two ends of the two sets of third springs 705 are fixedly connected to the cleaning brush 707 and the cleaning seat 4, respectively. The cam 706 is in contact with the cleaning brush 707 and interacts with the cleaning roller 707 during the winding process of the dustproof belt 503. The cleaning rollers 701, which are rotatably mounted on one side of the cleaning seat 4, scrape against each other, thus cleaning the dust adhering to the dustproof belt 503. The cylinder on the cleaning seat 4 is periodically activated to drive the sliding of the second rack 703, which, in conjunction with the second gear 702, causes the cleaning rollers 701 to rotate. The side of the cleaning rollers 701 with dust adhering to it corresponds to the cleaning brush 707. The motor inside the cleaning seat 4 drives the cam 706 to rotate, which, in conjunction with the slide rod 704 and the third spring 705, causes the cleaning brush 707 to slide back and forth on the cleaning seat 4, thus cleaning the dust on the cleaning rollers 701. The dust cleaned off the cleaning rollers 701 falls above the mounting box 3 and will not cause secondary pollution to the dustproof belt 503.

[0028] In this embodiment, reference Figure 6As shown, the positioning mechanism 6 includes two sets of slides 601 slidably mounted inside the writing board 2. Each set of slides 601 has a fixed insert rod 602, and the two insert rods 602 are respectively engaged with the pull rod 504. Each set of slides 601 has a fixed first rack 605. A rotating rod 606 is rotatably mounted inside the writing board 2, and a first gear 607 is sleeved on the rotating rod 606. The first gear 607 is located between the two sets of first racks 605, and the first gear 607 meshes with both sets of first racks 605 respectively. A positioning rod 611 is fixedly installed inside the writing board 2. A stop block 603 is fixedly sleeved on each of the two sets of insertion rods 602. A second spring 604 is sleeved on each of the two sets of insertion rods 602, and the two ends of the second spring 604 are fixedly connected to the stop block 603 and the writing board 2, respectively. A first torsion spring 608 is sleeved on the rotating rod 606, and the two ends of the first torsion spring 608 are fixedly connected to the first gear 607 and the writing board 2, respectively. A handle 609 is fixedly installed on the outer first rack 605, and a locking block 6 is fixedly installed on the handle 609. 10. Two sets of symmetrically distributed brackets 612 are sleeved on the positioning rod 611. A second torsion spring 613 is sleeved on the positioning rod 611. The two ends of the second torsion spring 613 are fixedly connected to the brackets 612 and the positioning rod 611, respectively. The two sets of brackets 612 are movably engaged with the locking block 610. Before using the writing board 2 and the slide rail 1, pull the two sets of pull rods 504 on the slide rail 1 toward the writing board 2. The handle 609 in the writing board 2 drives one of the first racks 605 to slide until the locking block 610 is inserted. Between the two sets of card holders 612, during the sliding process of the first rack 605, the first gear 607 is engaged to make the two sets of first racks 605 move synchronously in opposite directions, thereby causing the two sets of slides 601 and the insert rods 602 to move synchronously to both sides. After the pull rod 504 is inserted into the writing board 2, the card holder 612 is released from fixing the card block 610. Under the action of the second spring 604 and the first torsion spring 608, the two sets of insert rods 602 slide synchronously inward and fix the pull rod 504, and the dustproof tape 503 in the mounting box 3 covers the slide rail 1.

[0029] In this embodiment, before using the writing board 2 and the slide rail 1, pull the two sets of pull rods 504 on the slide rail 1 towards the writing board 2. The handle 609 on the writing board 2 drives one set of first racks 605 to slide until the locking block 610 is inserted between the two sets of brackets 612. During the sliding process, the first rack 605 cooperates with the first gear 607 to make the two sets of first racks 605 move synchronously in opposite directions, thereby causing the two sets of slides 601 and the insert rods 602 to move synchronously to both sides. After inserting the pull rod 504 into the writing board 2, release the brackets 612 from fixing the locking block 610. Under the action of the second spring 604 and the first torsion spring 608, the two sets of insert rods 602 slide synchronously inward and fix the pull rod 504. Cover the slide rail 1 with the dustproof tape 503 from the mounting box 3. During the movement of the writing board 2 on the slide rail 1, the dustproof tape 503, in conjunction with the coil spring 502 and the winding rod 501, ... The slide rail 503 slides out or retracts, covering the opening of the slide rail 1 to prevent dust from entering the slide rail 1 during use. At the same time, during the retraction of the dustproof belt 503, it scrapes against the cleaning roller 701 that is rotated on the corresponding side of the cleaning seat 4. The cleaning roller 701 cleans the dust adhering to the dustproof belt 503. The cylinder on the cleaning seat 4 is periodically activated to drive the sliding of the second rack 703, which, together with the second gear 702, makes the cleaning roller 701 rotate. The side of the cleaning roller 701 with dust adhering to it corresponds to the cleaning brush 707. The motor inside the cleaning seat 4 drives the cam 706 to rotate, which, together with the slide rod 704 and the third spring 705, makes the cleaning brush 707 slide back and forth on the cleaning seat 4 to complete the cleaning of the dust on the cleaning roller 701. The dust cleaned off the cleaning roller 701 falls above the mounting box 3 and will not cause secondary pollution to the dustproof belt 503.
