[0035] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0036] Please refer to Figure 1 and Figure 2 The conveying and tensioning mechanism 100 and the mahjong machine provided in the embodiment of the utility model can solve the above-mentioned problems, which will be described in detail below.

[0037] The conveying tensioning mechanism 100 includes a tensioning wheel 110, an inner bracket 120, an outer bracket 130 and a spring 140;

[0038] The two ends of the tension wheel 110 are rotatably connected to the inner bracket 120 , the inner bracket 120 is slidably accommodated in the outer bracket 130 , and the spring 140 is accommodated in the outer bracket 130 and abuts between the inner bracket 120 and the outer bracket 130 .

[0039] When in working condition, the tensioning wheel 110 is used to tension the transmission belt, and the inner bracket 120 can drive the tensioning wheel 110 to slide along the outer bracket 130. The outer bracket 130 can directly support the inner bracket 120, or support the inner bracket 120 through the spring 140. When the transmission belt tends to deflect, the spring 140 will be compressed by the inner bracket 120, and the spring 140 can reset itself, reducing the probability of deflection of the tensioning wheel 110 and the transmission belt, thereby reducing the failure rate of the mahjong machine and improving the user experience of the mahjong machine.

[0040] It should be noted that the inner bracket 120 is in a U-shaped structure, and the two ends of the tension wheel 110 are rotatably matched with the two ends of the U-shaped structure of the inner bracket 120. Specifically, the two ends of the tension wheel 110 can be provided with extension columns, and the two ends of the U-shaped structure of the inner bracket 120 are respectively provided with rotation holes, and the rotation holes are provided with bearings, and the bearing sleeves are provided on the extension holes; of course, the tension wheel 110 can also be provided with a second rotation hole along the axial direction, and the second rotation hole can rotatably accommodate a wheel axle, and the two ends of the wheel axle are connected to the two ends of the inner bracket 120.

[0041] Furthermore, the spring 140 is a pagoda spring 140, the top end area of ​​which is smaller than the bottom end area. When deflection occurs, the bottom end has better toughness and can therefore drive the top end to reset faster.

[0042] refer to Figure 1 , Figure 3 and Figure 4 In order to improve the relative sliding smoothness of the inner bracket 120 and the outer bracket 130, the inner bracket 120 and the outer bracket 130 can be respectively formed with a first sliding part 121 and a second sliding part 131, one of the first sliding part 121 and the second sliding part 131 is a slider and the other is a slide groove, and the slider and the slide groove slide together along the extension direction of the spring 140.

[0043] In this embodiment, the first sliding part 121 is a slider, and there are two sliders protruding from the two side walls of the first inner bracket 120; the second sliding part 131 is a slide groove, and there are two slide grooves disposed on the inner walls of both sides of the outer bracket 130. The top of the slide groove is an open structure, so that the slider can be placed into the slide groove from the top thereof.

[0044] Of course, in other embodiments of the present invention, the first sliding part 121 can also be a slide groove, and the second sliding part 131 can also be a slider; or the first sliding part 121 and the second sliding part 131 both include a slide groove and a slider, but it is necessary to ensure that the slide groove in the first sliding part 121 corresponds to the slider in the second sliding part 131, and the slider in the first sliding part 121 corresponds to the slide groove in the second sliding part 131.

[0045] refer to Figure 1 and Figure 2 The conveying tensioning mechanism 100 also includes a buckle 150, which is detachably connected to the upper side of the outer bracket 130. The buckle 150 is provided to buckle and limit the upper side of the outer bracket 130 to prevent the inner bracket 120 from easily sliding out from the top of the outer bracket 130.

[0046] refer to Figure 4 and Figure 5A first positioning portion 132 is formed on the outer bracket 130, and a second positioning portion 151 is formed on the buckle 150. One of the first positioning portion 132 and the second positioning portion 151 is a positioning groove, and the other is a positioning block, and the positioning groove cooperates with the positioning block.

[0047] In this embodiment, the first positioning portion 132 is a positioning block, the second positioning portion 151 is a positioning groove, and the positioning block is protruding from the positioning groove, and the positioning block is used to resist the inner bracket 120. It can be understood that during the connection process between the buckle 150 and the outer bracket 130, the first positioning portion 132 and the second positioning portion 151 can be used to achieve rough positioning of the two, and then the two are locked and connected by a buckle or a threaded structure; when the inner bracket 120 has a movement tendency to separate from the outer bracket 130 from the top, the buckle 150 can limit the inner bracket 120, thereby preventing the inner bracket 120 from separating from the external bracket.

[0048] Of course, in other embodiments of the present invention, the first positioning portion 132 may be a positioning groove, and the second positioning portion 151 may be a positioning block; in addition, the first positioning portion 132 and the second positioning portion 151 may both include a positioning groove and a positioning block, and the positioning groove in the first positioning portion 132 cooperates with the positioning block in the second positioning portion 151, and the positioning block in the first positioning portion 132 cooperates with the positioning groove in the second positioning portion 151.

[0049] refer to Figure 2-Figure 4 Because the spring 140 has a certain amount of movable space on the inner side of the outer bracket 130, in order to prevent the spring 140 from easily detaching from between the outer bracket 130 and the inner bracket 120, a first accommodating groove 122 can be formed on the bottom wall of the inner bracket 120, and the top end of the spring 140 is accommodated in the first accommodating groove 122, and a second accommodating groove 133 is formed on the outer bracket 130, and the bottom end of the spring 140 is accommodated in the second accommodating groove 133, thereby playing a role of accommodating and limiting the two ends of the spring 140 through the first accommodating groove 122 and the second accommodating groove 133.

[0050] Furthermore, in order to further ensure the stability of the spring 140, a limiting column 123 may be formed on the bottom wall of the inner bracket 120, and the top end of the spring 140 is sleeved on the limiting column 123. Specifically, the limiting column 123 protrudes from the bottom wall of the first receiving groove 122, and then the limiting column 123 and the first receiving groove 122 simultaneously limit the inner and outer sides of the top end of the spring 140.

[0051] refer to Figure 2 and Figure 4The outer bracket 130 includes a support plate 1301 and two pillars 1302. The two pillars 1302 are arranged opposite to each other and located on the upper side of the support plate 1301. The inner bracket 120 and the spring 140 are both located on the upper side of the support plate 1301 and between the two pillars 1302. The inner bracket 120 slides with the two pillars 1302.

[0052] Specifically, the two pillars 1302 are arranged along the axial direction of the tensioning wheel 110, the second sliding portion 131 and the first positioning portion 132 are both formed on the pillars 1302, the second sliding portion 131 with a sliding groove structure is formed on the inner walls of the two pillars 1302 close to each other, and the first positioning with a positioning groove structure is not formed on the top surfaces of the two pillars 1302.

[0053] Furthermore, the outer bracket 130 also includes two baffles 1303 arranged opposite to each other. The two baffles 1303 are arranged on the upper side of the support plate 1301 and are located between the two pillars 1302. The top end of the tensioning wheel 110 protrudes from the baffle 1303. By setting the baffle 1303, it is used to shield and protect the inner bracket 120 and the spring 140 below the tensioning wheel 110. On the one hand, it can prevent the mixing of foreign substances that affect the sliding fit between the inner bracket 120 and the outer bracket 130 and the expansion and compression movement of the spring 140. On the other hand, it can limit the inner bracket 120 and the spring 140 to prevent them from falling out of the gap between the two pillars 1302.

[0054] The embodiment of the utility model further provides a mahjong machine, comprising the above-mentioned conveying tensioning mechanism 100, and also comprising a table body and a conveyor belt, wherein the conveying tensioning mechanism 100 and the conveyor belt are both arranged in the table body, and the tensioning wheel 110 is used to tension the conveyor belt. The mahjong machine comprises the conveying tensioning mechanism 100, which has all the functions of the conveying tensioning mechanism 100.

[0055] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
