A folding treadmill

(一)技术领域(1) Technical field

本发明涉及一种折叠式跑步机。The invention relates to a folding treadmill.

(二)背景技术(2) Background technology

现有的折叠式跑步机均包括底座架、枢接在所述底座架上的跑步板，跑步板与底座架通过气弹簧连接，气弹簧包括缸管和活塞杆，缸管的上端为封闭端下端为开口端，活塞杆由缸管的开口端气密地伸入该的缸管内，缸管的上端枢接在所述跑步板的背面，活塞杆的下端枢接在底座架上，活塞杆具有跑步板上抬至一定角度时缸管的开口端可支撑于其上的支撑部，一般来说活塞杆由上部的小直径部和下部的大直径部组成，大直径部的上端面即构成支撑部。平常不使用跑步机时，将跑步板上抬，抬至活塞杆的支撑部经过缸管的开口端时，缸管的开口端支撑在支撑部上，跑步机处于折叠状态。当需要使用跑步机时，用脚踢一下缸管，活塞杆即可重新套入缸管中。Existing folding treadmills all include a base frame and a running board pivotally connected to the base frame. The running board and the base frame are connected by a gas spring. The gas spring includes a cylinder tube and a piston rod. The upper end of the cylinder tube is a closed end. The lower end is an open end, and the piston rod is airtightly stretched into the cylinder tube from the open end of the cylinder tube. The upper end of the cylinder tube is pivotally connected to the back of the running board, and the lower end of the piston rod is pivotally connected to the base frame. It has a support part on which the open end of the cylinder tube can be supported when the running board is lifted to a certain angle. Generally speaking, the piston rod is composed of a small diameter part on the upper part and a large diameter part on the lower part, and the upper end surface of the large diameter part is formed. support section. When the treadmill is not used normally, the running board is lifted until the support portion of the piston rod passes through the open end of the cylinder tube, the open end of the cylinder tube is supported on the support portion, and the treadmill is in a folded state. When the treadmill needs to be used, the cylinder tube can be kicked once with the foot, and the piston rod can be inserted into the cylinder tube again.

现有的这种折叠式跑步机还存在的缺点是：1.需使用跑步机时，采用脚踢的方式操作气弹簧，容易产生损坏。2.气弹簧上没有保险装置，若不小心碰到缸管，跑步板也会翻折下来，极易产生误操作，特别是好动的小孩如产生误操作的话极易产生危险。The shortcoming that also exists in this existing foldable treadmill is: 1. When needing to use treadmill, adopt the mode of kicking to operate gas spring, easily produce damage. 2. There is no safety device on the gas spring. If you accidentally touch the cylinder tube, the running board will fold down, which is very easy to cause misoperation, especially for active children. If misoperation occurs, it is very easy to cause danger.

(五)具体实施方式(5) Specific implementation methods

下面结合附图和具体实施方式对本发明作进一步详细说明。The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

参照图1、图2、图3、图4、图5、图6、图7、图8，一种折叠式跑步机，包括底座架1、枢接在所述底座架1上的跑步板2，所述的跑步板2与所述的底座架1通过气弹簧连接，所述的气弹簧包括缸管3和活塞杆4，所述缸管3的上端为封闭端下端为开口端，所述的活塞杆4由所述的开口端气密地伸入所述的缸管3内，所述缸管3的上端枢接在所述跑步板2的背面，所述活塞杆4的下端枢接在所述的底座架1上。Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, a folding treadmill comprises a base frame 1, a running board 2 pivotally connected to the base frame 1 , the running board 2 is connected with the base frame 1 through a gas spring, the gas spring includes a cylinder tube 3 and a piston rod 4, the upper end of the cylinder tube 3 is a closed end and the lower end is an open end, the The piston rod 4 is airtightly stretched into the cylinder tube 3 from the open end, the upper end of the cylinder tube 3 is pivotally connected to the back side of the running board 2, and the lower end of the piston rod 4 is pivotally connected On the base frame 1 described above.

参照图6，所述的活塞杆由上部的小直径部5和下部的大直径部6组成，所述大直径部6的上端面构成支撑部7，跑步板2上抬至一定角度时缸管3的开口端可支撑于该支撑部7上。Referring to Figure 6, the piston rod is composed of an upper small-diameter portion 5 and a lower large-diameter portion 6, the upper end surface of the large-diameter portion 6 constitutes a support portion 7, and when the running board 2 is lifted to a certain angle, the cylinder tube The open end of 3 can be supported on the supporting part 7 .

还包括一固定套8，所述的固定套8套设于所述缸管3的下端，由螺丝9固定，固定套的下端略低于缸套的下端。所述固定套8的外侧(即背向跑步板的一侧)铰接有可从所述固定套8的下端卡入所述固定套内的卡钩10，该卡钩10位于所述固定套8的下端。所述卡钩10的上部穿设有拉杆11，所述卡钩10的下部穿设有拉环12，所述的活塞杆4穿设于所述的拉环12内。It also includes a fixed sleeve 8, the fixed sleeve 8 is sleeved on the lower end of the cylinder tube 3 and fixed by screws 9, the lower end of the fixed sleeve is slightly lower than the lower end of the cylinder liner. The outer side of the fixed sleeve 8 (that is, the side facing away from the running board) is hinged with a hook 10 that can be snapped into the fixed sleeve from the lower end of the fixed sleeve 8, and the hook 10 is located on the fixed sleeve 8. the lower end. The upper part of the hook 10 is pierced with a pull rod 11 , and the lower part of the hook 10 is pierced with a pull ring 12 , and the piston rod 4 is pierced in the pull ring 12 .

所述跑步板2的背面设有定位板13，所述拉杆11的上端穿越所述的定位板13而定位。The back side of the running board 2 is provided with a positioning plate 13, and the upper end of the pull rod 11 passes through the positioning plate 13 for positioning.

平常不使用跑步机时，将跑步板2上抬，抬至活塞杆的支撑部7经过缸管3的开口端时，缸管3的开口端支撑在支撑部7上，跑步机处于折叠状态，此时固定套8和活塞杆4之间具有间隙，将卡钩10卡入该间隙内，使活塞杆4得以相对固定，使之无法回退到缸管内，因此不会产生误操作。当需要使用跑步机时，上拉拉杆11，拉杆11拉动卡钩10旋转，使卡钩10退出固定套和活塞杆之间的间隙，继续上拉拉杆11，则拉环12开始与活塞杆4相接触，并拉动活塞杆4回退，当活塞杆4回退至缸管3内后，跑步板即在气弹簧的作用下慢慢向下翻折。When the treadmill is not used normally, the running board 2 is lifted until the support portion 7 of the piston rod passes through the open end of the cylinder tube 3, the open end of the cylinder tube 3 is supported on the support portion 7, and the treadmill is in a folded state. At this time, there is a gap between the fixed sleeve 8 and the piston rod 4, and the hook 10 is snapped into the gap, so that the piston rod 4 can be relatively fixed so that it cannot be retracted into the cylinder tube, so misoperation will not occur. When needing to use the treadmill, pull up the pull rod 11, the pull rod 11 pulls the hook 10 to rotate, makes the grab 10 withdraw from the gap between the fixed sleeve and the piston rod, and continues to pull the pull rod 11, then the pull ring 12 starts to contact with the piston rod 4 Contact each other, and pull the piston rod 4 to retreat. When the piston rod 4 retreats into the cylinder tube 3, the running board is slowly folded down under the action of the gas spring.

若固定套的位置稍靠上，固定套的下端与缸套的下端平齐或固定套的下端略高于缸套的下端，则将跑步板上抬至活塞杆的支撑部经过缸管的开口端时，缸管的开口端支撑在支撑部上，跑步机处于折叠状态，此时缸套和活塞杆之间具有间隙，将卡钩卡入该间隙内，同样可使活塞杆得以相对固定。If the position of the fixed sleeve is slightly higher, the lower end of the fixed sleeve is flush with the lower end of the cylinder liner or the lower end of the fixed sleeve is slightly higher than the lower end of the cylinder liner, then lift the running board until the support part of the piston rod passes through the opening of the cylinder tube At the end, the open end of the cylinder tube is supported on the supporting part, and the treadmill is in the folded state. At this time, there is a gap between the cylinder liner and the piston rod, and the hook is inserted into the gap, which can also make the piston rod relatively fixed.

为了进一步防止误操作，如图7所示，定位板13上开设有定位孔14，设计定位孔14由圆孔和条形孔组成，拉杆11的上部具有挡片15，所述挡片15的尺寸使其能通过所述的圆孔而无法通过所述的条形孔。缸管与活塞杆处于锁定状态时拉杆11位于条形孔内且挡片15位于定位板13的下方，此时由于挡片15的阻挡作用拉杆11无法上拉。需要上拉拉杆时将拉杆11上推至圆孔处，才能将拉杆11往上拉。In order to further prevent misoperation, as shown in Figure 7, a positioning hole 14 is provided on the positioning plate 13, and the positioning hole 14 is designed to be composed of a round hole and a strip hole. The size makes it pass through the round hole but not through the strip hole. When the cylinder tube and the piston rod were in the locked state, the pull rod 11 was located in the strip hole and the catch plate 15 was located under the positioning plate 13. Now, due to the blocking effect of the catch plate 15, the pull rod 11 could not be pulled up. When the pull rod needs to be pulled up, the pull rod 11 can be pushed up to the round hole, so that the pull rod 11 can be pulled up.

当然，活塞杆形成用于支撑缸管的支撑部的结构形式并不局限于上述描述，如图9所示，活塞杆4上设有凸台16，所述的凸台16亦可构成支撑部。Certainly, the structural form that the piston rod forms the supporting part for supporting the cylinder tube is not limited to the above description, as shown in Figure 9, the piston rod 4 is provided with a boss 16, and the boss 16 can also constitute a supporting part .
