Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mahjong machines, and specifically to a card-raising bar roller guide mechanism. Background Art
[0002] The working principle of the mahjong machine is based on magnetic and mechanical automation technology, and is designed to shuffle and distribute mahjong tiles quickly and efficiently. The card raising bar of the existing mahjong machine is usually driven by a cam power structure at the bottom to move up and down, raising the arranged mahjong tiles to a position flush with the tabletop, such as Figure 1 and Figure 2 As shown, four notches 2 are arranged on the table top 1 of the mahjong machine, and the four notches 2 are for four card-raising bars 3 to be raised and lowered. A card-blocking plate 4 is arranged below the notches 2. There is a certain gap between the card-raising bars 3 and the card-blocking plate 4. After long-term use, the internal mechanical structure of the mahjong machine may produce slight deformation due to frequent use and heavy pressure. The card-raising bars 3 will gradually approach the card-blocking plate 4, so that the gap will gradually narrow, and finally the card-raising bars 3 will contact with the card-blocking plate 4, resulting in the card-raising bars 3 not being raised and lowered smoothly, and even the card-raising bars 3 may be stuck during lifting, affecting the normal operation of the mahjong machine. Utility Model Content
[0003] The utility model aims to provide a card-lifting bar roller guide mechanism, which solves the technical problem that the card-lifting bar cannot be lifted smoothly due to the reduced gap between the card-lifting bar and the card-blocking plate after long-term use in the existing mahjong machine.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] A roller guide mechanism for a lifting bar comprises a mounting support, which is fixed at the bottom of the lifting bar, and a support bearing is rotatably mounted at the end of the mounting support, wherein the outer ring of the support bearing protrudes from the side of the lifting bar.
[0006] Furthermore, a long hole is opened on the mounting support, and the mounting support is fixed to the bottom of the brand-raising strip by a plurality of bolts, and the bolts are arranged in the long hole.
[0007] Furthermore, the support bearing is a self-lubricating bearing.
[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model ensures the gap between the card raising bar and the card baffle plate by arranging a support bearing to support the card baffle plate on the mahjong machine, so that the card raising bar can be raised and lowered smoothly. The utility model reduces the direct friction between components and extends the service life of the equipment. Through a simple adjustment mechanism, corresponding fine-tuning can be performed when the equipment is aged or deformed to maintain a good operating state. In addition, the use of support bearings can also reduce vibration and noise, and improve the overall stability and user experience of the mahjong machine. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The accompanying drawings are used to provide a further understanding of the present utility model and constitute a part of the specification. Together with the embodiments of the present utility model, they are used to explain the present utility model and do not constitute a limitation to the present utility model. In the accompanying drawings:
[0010] Figure 1 It is a schematic diagram of the position of the card-lifting strip of the existing mahjong machine on the tabletop;
[0011] Figure 2 It is a diagram showing the positional relationship between the card-lifting strip and the card-blocking plate of the existing mahjong machine;
[0012] Figure 3 It is a schematic structural diagram of a card-lifting strip roller guiding mechanism;

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0015] The present utility model will be further described in detail below in conjunction with the embodiments.
[0016] As Figure 3 and Figure 4 shown, a specific embodiment of a card-lifting strip roller guiding mechanism provided by the present utility model:
[0017] A card-lifting strip roller guiding mechanism includes a mounting support member 100. The mounting support member 100 is fixed to the bottom of the card-lifting strip 3. A support bearing 101 is rotatably mounted at the end of the mounting support member 100. The outer ring of the support bearing 101 protrudes from the side surface of the card-lifting strip 3. After installation, a part of the support bearing 101 is located in the gap between the card-lifting strip 3 and the card-blocking plate. As the card-lifting strip 3 moves up and down, the support bearing 101 contacts the card-blocking plate 4. The setting of the support bearing 101 provides support for the up and down movement of the card-lifting strip 3 and prevents it from getting stuck when contacting the card-blocking plate 4.
[0018] The mounting support member 100 is provided with a long hole 102. The mounting support member 100 is fixed to the bottom of the card-lifting strip 3 by a plurality of bolts 103, and the bolts 103 are arranged in the long hole 102. The provision of the long hole 102 provides space for adjusting the position of the support bearing 101, allowing the card-lifting strip 3 to finely adjust its position relative to the card-blocking plate 4 within a certain range to adapt to minor changes or wear in the internal structure of the mahjong machine.
[0019] It should be noted that in this text, terms such as "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
