Description

Technical Field

[0001] The utility model relates to the technical field of roller skates, in particular to an improved double-triangle roller skate. Background Art

[0002] As people pursue a more leisure and sports lifestyle, roller skating or inline skating has gradually become more popular. Although traditional roller skates or inline skates have made some progress in terms of functionality and comfort, they still have some shortcomings in adapting to different foot shapes and sizes.

[0003] For example, authorization publication number CN221061696U discloses a pair of roller skates for learning to walk that facilitate wheel locking. The roller skates include an adjustment device comprising an adjustment plate and a bolt. The adjustment plate is disposed on the top surface of the foot support seat. The adjustment plate is provided with a plurality of first sliding grooves extending vertically therethrough, each extending along the length of the foot support seat. The foot support seat is provided with a plurality of latching pins that cooperate with the first sliding grooves. The adjustment plate is provided with a threaded clamping block on the bottom surface, and the threaded clamping block can be movably extended forward and backward into the interior of the second support block. The bolt is inserted into and clamped within the interior of the second support block and is threadedly connected to the threaded clamping block. The head of the bolt is exposed outside the second support block. Two circular rings are provided at intervals on the shank of the bolt, forming an annular clamping cavity between the two circular rings. A U-shaped protrusion is formed on the inner sidewall of the second support block for engaging with the annular clamping cavity.

[0004] During adjustment, an adjusting plate needs to be provided inside the shoe body. By driving the bolt, the adjusting plate moves linearly along the length direction of the foot support plate, thereby achieving the technical effect of adjusting the length of the skates. However, this method of providing an adjusting device inside the shoe body and adjusting the size of the skates by extending and retracting the adjusting device inside the shoe body cannot adjust the length of the skate body, which results in a smaller foot wearing a larger shoe being uncomfortable due to the mismatch between the shoe and the foot.

[0005] Therefore, it is necessary to make further improvements to the existing technology. Utility Model Content

[0031] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the utility model.

[0032] like Figure 1-Figure 5 As shown, an improved double triangle roller skate includes a shoe body 1, a toe 2, an adjusting screw 3, a threaded fixing member 4, a pulley bracket 5 and a pulley 6;

[0033] A pulley bracket 5 is fixedly mounted on the bottom of the shoe body 1, and pulleys 6 are rotatably mounted on the bottom of the pulley bracket 5. Specifically, there are four pulleys 6, two of which are mounted front-to-back between the two side walls of the pulley bracket 5, and the other two pulleys 6 are mounted on either side of the rear end of the pulley bracket 5. More specifically, each pulley 6 is provided with a transmission rod 7, each of which is connected to the pulley bracket 5. This arrangement creates a triangular arrangement of the four pulleys 6, ensuring the roller skates maintain balance and are suitable for beginners.

[0034] like Figure 3-Figure 4 As shown, in this embodiment, a locking device 8 for locking the pulley 6 is further provided at the bottom of the pulley bracket 5 .

[0035] like Figure 4 As shown, "L-shaped" sliding grooves 21 are symmetrically opened on the left and right sides of the bottom of the toe 2. The end of the shoe body 1 close to the toe 2 can be inserted into the sliding groove 21 and slide back and forth in the sliding groove 21; through the above-mentioned arrangement, the toe 2 and the shoe body 1 can adjust the length of the entire roller skate after sliding in coordination.

[0036] like Figure 3 As shown, guide columns 11 are respectively provided on the left and right sides of the front end of the shoe body 1 and the rear end of the shoe body 1, and guide grooves 22 for the guide columns 11 to slide are respectively provided on the left and right sides of the front end of the toe 2 and the rear end of the toe 2, so that the sliding of the toe 2 and the shoe body 1 is smoother through the cooperation and guidance of the guide columns 11 and the guide grooves 22.

[0037] like Figure 2-Figure 4As shown, the threaded fixing part 4 is fixed to the rear end of the toe cap 2, and the adjusting screw 3 can pass through the rear side of the shoe body 1 and be threadedly connected to the threaded fixing part 4. By rotating the adjusting screw 3, the toe cap 2 can be driven closer to or farther away from the shoe body 1 to adjust the size of the roller skates; specifically, when the toe cap 2 is closer to the shoe body 1, the length of the roller skates is reduced; when the toe cap 2 is farther away from the shoe body 1, the length of the roller skates is increased.

[0038] The threaded fastener 4 is fixed to the toe cap with rivets, allowing for the use of either plastic or metal depending on the size of the roller skate. In this embodiment, when the roller skate is smaller, a plastic or metal threaded fastener 4 can be used during processing; when the roller skate is larger, a metal threaded fastener 4 can be used to meet structural strength requirements.

[0039] like Figure 5 As shown, the threaded fixing member 4 includes an integrally formed fixing plate 41 and a threaded member 42. The threaded member 42 relatively protrudes from the lower end surface of the fixing plate 41. A threaded hole 43 is formed through one side of the threaded member 42, through which the adjusting screw 3 passes. In this embodiment, the threaded fixing member 4 is disposed on the toe cap 2, wherein the adjusting screw 3 extends into the threaded hole 43 and forms a threaded connection with the threaded fixing member 4. When the adjusting screw 3 rotates, one end of the adjusting screw 3 drives the threaded fixing member 4 and the toe cap 2 to slide, thereby adjusting the size of the roller skates by sliding the toe cap 2.

[0040] like Figure 2 As shown, a movable groove 12 is provided at the rear end of the shoe body 1, and the threaded member 42 can extend into the movable groove 12 and slide in the movable groove 12 by the drive of the adjusting screw 3. Through the above arrangement, the threaded fixing member 4 can slide in a directional manner in the movable groove 12.

[0041] like Figure 5 As shown, a mounting groove 23 for matching and mounting a fixing plate 41 is provided at the rear end of the toe cap 2, and a first through hole 24 for passing a screw member 42 is provided in the mounting groove 23. In this embodiment, the mounting groove 23 is used for positioning and mounting the screw fixing member 4.

[0042] like Figure 5 As shown, first mounting holes 44 are respectively defined on the front and rear sides of the fixing plate 41, and second mounting holes 25 corresponding to the first mounting holes 44 are respectively defined in the mounting groove 23. In this embodiment, screws can be provided between the first mounting holes 44 and the second mounting holes 25 to securely connect the fixing plate 41 to the toe cap 2.

[0043] like Figure 2-Figure 5As shown, the guide groove 22 includes a first guide groove 220 that is arranged at the rear end of the toe cap 2 and symmetrically arranged on both sides thereof, and a strip groove 410 corresponding to the first guide groove 220 is symmetrically opened on the left and right sides of the fixing plate 41; the guide column 11 includes a first guide column 110 that is arranged at the rear end of the shoe body 1 and symmetrically arranged, and the first guide column 110 can pass through the first guide groove 220 and the strip groove 410 corresponding thereto. Through the above-mentioned arrangement, the two first guide columns 110 are respectively inserted into the first guide groove 220 and the strip groove 410, so that when the toe cap 2 slides, it can form a directional movement through the cooperation of the first guide column 110, the first guide groove 220 and the strip groove 410; at the same time, when the first guide column 110, the first guide groove 220 and the strip groove 410 are arranged on both sides, the toe cap 2 is more balanced when sliding.

[0044] like Figure 2-Figure 5 As shown, the guide groove 22 further includes a second guide groove 221 provided at the front end of the toe cap 2, and the guide post 11 further includes a second guide post 111 provided at the front end of the shoe body 1 and corresponding to the second guide groove 221.
