Description

Technical Field

[0001] This utility model relates to the field of skis, and in particular to a locking device for a folding ski. Background Technology

[0002] In northern my country during winter, ice skating and skiing have become essential winter tourism activities, attracting tourists from all over the world. Among them are many experts, but most people neither ice skate nor ski. Common equipment includes sleds, ice skates, skis, snowmobiles, and ice sleds requiring special tracks, necessitating the construction of specialized venues and related facilities, and requiring significant investment. Snowboards and road skis have long been used for recreational and competitive purposes. Current folding snowboards are typically large, making assembly inconvenient and time-consuming, and their locking mechanisms lack structural stability. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a locking device for folding skis, which solves the issues of inconvenient installation or folding of skis and low stability of the locking device structure.

[0004] The technical solution adopted by this utility model is: a locking device for a folding ski, including a ski body, a handrail frame, and a support frame. The handrail frame and the support frame are rotatably connected to the ski body. It also includes a mounting shell and a snap-fit ​​plate. The mounting shell is provided with a mounting plate, which cooperates with the snap-fit ​​plate to snap the handrail frame. The mounting shell is mounted on the support frame. A connector is provided between the mounting shell and the snap-fit ​​plate. The connector includes a bolt and a nut. A first mounting hole and a second mounting hole are respectively opened on both sides of the mounting shell. The first mounting hole is connected to the nut. The bolt is provided with a smooth part and a threaded part. The bolt passes through the first mounting hole and the second mounting hole and is threadedly connected to the nut by the threaded part. The snap-fit ​​plate is rotatably connected to the smooth part.

[0005] With the above technical solution, when assembling, the user first fixes the mounting shell to the support frame, then rotates the support frame to engage the mounting plate and the snap-fit ​​plate to snap onto the handrail, thus completing the installation; when folding the ski, rotating the snap-fit ​​plate will disengage it from the handrail; the connecting parts between the mounting shell and the snap-fit ​​plate consist of bolts and nuts, and the snap-fit ​​plate is rotatably connected to the smooth part on the bolt. The operation of snapping or disengaging the handrail with this utility model is convenient and quick, and the structural stability is improved.

[0006] Furthermore, the circumferential profile of the nut is not perfectly circular, and the first mounting hole is adapted to the nut.

[0007] With the above technical solution, when installing nuts and bolts, the nuts can be fixed in the first mounting hole, which facilitates bolt installation.

[0008] Furthermore, the edge of the first mounting hole is provided with a bevel, the bevel facing outwards from the snap-fit ​​plate.

[0009] With the above technical solution, when installing the nut, the inclined plane guides the nut, making it easier to install the nut into the first mounting hole.

[0010] Furthermore, the snap-fit ​​plate is provided with an arc-shaped portion, which has elastic deformation capability, and the central angle of the arc-shaped portion is greater than 180°.

[0011] Through the above technical solution, during the snap-fit ​​process between the arc-shaped part and the handrail frame, the arc-shaped part undergoes elastic deformation, making the connection between the arc-shaped part and the handrail frame more stable.

[0012] Furthermore, an arc-shaped plate extends from the mounting plate, and the arc-shaped plate is symmetrically arranged on both sides of the snap-fit ​​plate.

[0013] Through the above technical solution, the curved plate contacts the handrail frame to achieve positioning, which facilitates the snap-fit ​​plate to snap-fit ​​the handrail frame.

[0014] Furthermore, the radius of the circle containing the arc-shaped portion is equal to the radius of the circle containing the arc-shaped plate, and when the snap-fit ​​plate snaps into the handrail frame, the arc-shaped portion and the arc-shaped plate are concentric.

[0015] With the above technical solution, the connection between the handrail frame, the snap-fit ​​plate, and the mounting shell will be more stable.

[0016] Furthermore, the snap-fit ​​plate is provided with a lever, which is located on the arc-shaped portion.

[0017] With the above technical solution, the lever can easily bear force when installing or dismantling the snap-fit ​​plate and the handrail frame, making the installation or dismantling of the snap-fit ​​plate and the handrail frame easier.

[0018] Furthermore, the mounting shell includes an arc-shaped shell, a first side plate, and a second side plate. The mounting shell has elastic deformation capability. The first side plate and the second side plate are located on both sides of the arc-shaped shell, and the gap between the first side plate and the second side plate gradually decreases away from the arc-shaped shell. The inner side of the arc-shaped shell is adapted to the support frame.

[0019] With the above technical solution, when the mounting shell and the support frame are installed, the first side plate and the second side plate can elastically deform, making the connection between the mounting shell and the support frame more secure. Attached Figure Description

[0033] See Figures 1-6 A locking device for a folding ski includes a ski body 1, a handrail frame 2, and a support frame 3. The handrail frame 2 and the support frame 3 are rotatably connected to the ski body 1. The device also includes a mounting shell 4 and a snap-fit ​​plate 5. The mounting shell 4 has a mounting plate 401, which engages with the snap-fit ​​plate 5 to snap the handrail frame 2. The mounting shell 4 is mounted on the support frame 3. A connector 6 is provided between the mounting shell 4 and the snap-fit ​​plate 5. The connector 6 includes a bolt 601 and a nut 602. The mounting shell 4 has a first mounting hole 402 and a second mounting hole 403 on its two sides. The first mounting hole 402 is connected to the nut 602. The bolt 601 has a smooth part 6011 and a threaded part 6012. The bolt 601 passes through the first mounting hole 402 and the second mounting hole 403 and is threadedly connected to the nut 602 using the threaded part 6012. The snap-fit ​​plate 5 is rotatably connected to the smooth part 6011.

[0034] When assembling the skis, the user first fixes the mounting shell 4 to the support frame 3, then rotates the support frame 3 to engage the mounting plate 401 and the snap-fit ​​plate 5 to snap the handrail frame 2, thus completing the installation. When folding the skis, rotating the snap-fit ​​plate 5 will disengage it from the handrail frame 2. The connecting piece 6 between the mounting shell 4 and the snap-fit ​​plate 5 consists of a bolt 601 and a nut 602. The snap-fit ​​plate 5 is rotatably connected to the smooth part 6011 on the bolt 601. The snap-fit ​​and disengagement operation of this utility model with the handrail frame 2 is convenient and quick, and the structural stability is improved.

[0035] See Figure 2 , Figure 3 The circumferential profile of nut 602 is not a perfect circle, and the first mounting hole 402 is adapted to nut 602.

[0036] When the nut 602 and the bolt 601 are installed, the nut 602 can be fixed in the first mounting hole 402, which facilitates the installation of the bolt 601.

[0037] Preferably, both the nut 602 and the first mounting hole 402 are regular hexagons.

[0038] See Figure 3 The edge of the first mounting hole 402 is provided with a bevel 404, which faces the outside of the snap-fit ​​plate 5.

[0039] When installing nut 602, the inclined surface 404 guides nut 602, making it easier for nut 602 to be installed into the first mounting hole 402.

[0040] See Figure 2 , Figure 6 The snap-fit ​​plate 5 is provided with an arc-shaped part 501, which has elastic deformation capability and the central angle of the arc-shaped part 501 is greater than 180°.

[0041] The part where the handrail frame 2 and the arc-shaped part 501 are engaged is cylindrical. During the engagement process between the arc-shaped part 501 and the handrail frame 2, the arc-shaped part 501 undergoes elastic deformation, which connects the arc-shaped part 501 and the handrail frame 2. The arc-shaped part 501 and the handrail frame 2 are not easy to separate, and the connection is more stable.

[0042] The preferred arc portion 501 has a central angle of 190°, and the preferred material of the snap-fit ​​plate 5 is plastic.

[0043] See Figure 2 , Figure 3 An arc-shaped plate 405 extends from the mounting plate 401, and the arc-shaped plate 405 is symmetrically arranged on both sides of the snap-fit ​​plate 5.

[0044] The curved plate 405 contacts the handrail frame 2 to achieve positioning, which facilitates the snap-fit ​​plate 5 to snap-fit ​​the handrail frame 2.

[0045] See Figure 2 The radius of the circle containing the arc-shaped part 501 is equal to the radius of the circle containing the arc-shaped plate 405. When the snap-fit ​​plate 5 is snapped into the handrail frame 2, the arc-shaped part 501 and the arc-shaped plate 405 are concentric.

[0046] The connection between the handrail 2, the snap-fit ​​plate 5, and the mounting shell 4 will be more stable.

[0047] See Figure 2 , Figure 6 The snap-fit ​​plate 5 is provided with a paddle 502, which is located on the arc-shaped part 501.

[0048] When installing or removing the snap-fit ​​plate 5 and the handrail frame 2, the lever 502 facilitates force application, making the installation or removal of the snap-fit ​​plate 5 and the handrail frame 2 easier.

[0049] See Figure 3 , Figure 5 The mounting shell 4 includes an arc-shaped shell 406, a first side plate 407 and a second side plate 408. The mounting shell 4 has elastic deformation capability. The first side plate 407 and the second side plate 408 are located on both sides of the arc-shaped shell 406, and the gap between the first side plate 407 and the second side plate 408 gradually decreases away from the arc-shaped shell 406. The inner side of the arc-shaped shell 406 is adapted to the support frame 3.

[0050] When the mounting shell 4 is installed with the support frame 3, the first side plate 407 and the second side plate 408 can elastically deform, making the connection between the mounting shell 4 and the support frame 3 more secure.

[0051] The preferred material for the mounting shell 4 is plastic.

[0052] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
