Description

Technical Field

[0001] This utility model relates to the field of roller skate brake accessories, specifically to roller skate brake components and adapters used in roller skate brake structures. Background Technology

[0002] Traditional roller skate braking structures, such as the adjustable roller skate braking structure disclosed in Chinese invention application CN1978017A, include a rubber brake head with a screw. The screw head is embedded in the center of the rubber brake head, and the screw thread extends out of the rubber brake head and screws into a brake nut embedded in the skate's upper. The rubber brake head is a consumable part and often needs to be replaced due to wear after a period of use. However, in this case, the screw head of the rubber brake head is embedded inside the rubber brake head, such as... Figure 1 As shown, the screws of this type of integrated brake head are large-sized screws. When the rubber brake head is replaced, the screws are also discarded, resulting in waste and high replacement costs.

[0003] Therefore, some roller skates use a separate brake head where the screws can be separated from the rubber brake head, such as... Figure 2 As shown, however, if the connecting hole on the brake head is too large, it will affect the mechanical performance of the brake head. Therefore, the screw diameter of this type of split brake head is smaller than that of the screw body of the one-piece brake head. It is only suitable for ice skates with small-diameter connecting screw holes produced by the corresponding manufacturer, and cannot be used on ice skates with one-piece brake heads. Utility Model Content

[0004] The purpose of this utility model is to provide an adapter for use in the braking structure of an ice skate. The adapter includes a cylindrical part and a brim part. The brim part is formed at one end of the cylindrical part and has a diameter larger than that of the cylindrical part. The adapter has a threaded hole that passes through the brim part and the cylindrical part. The threaded hole is used for connecting the brake head. The cylindrical part has an external thread for screwing into a nut installed on the sole of the ice skate.

[0005] Another objective of this utility model is to provide a brake assembly for roller skates, including a brake head, the aforementioned adapter, and a screw for connecting the brake head and the adapter; the brake head is provided with a connecting hole, the brake head abuts against the cap edge of the adapter, and the screw body passes through the connecting hole and is screwed into the threaded hole.

[0006] Furthermore, a limiting structure is provided between the brake head and the adapter to restrict the rotation of the brake head relative to the adapter. The limiting structure includes a limiting protrusion on the cap edge of the adapter and a limiting groove on the brake head, wherein the limiting protrusion falls into the limiting groove.

[0007] The connection hole includes a countersunk portion for screw insertion and for receiving the screw head; the depth of the countersunk portion is greater than the thickness of the screw head.

[0008] The brake head is made of rubber.

[0009] The skate brake assembly also includes a nut for mounting on the sole of the skate for screwing into the cylindrical portion of the adapter; the nut has an internal thread, and the external thread of the cylindrical portion screws into the internal thread of the nut.

[0010] The adapter in this technical solution can be connected to the nut installed on the sole of the skate via the column part. The threaded hole of the adapter is for connecting to the brake head with a small screw, so that the skate can be equipped with the original one-piece brake head or replaced with a split brake head.

[0011] The combined roller skate brake assembly of this technical solution can replace the existing one-piece brake head and be used with roller skates. The brake head and adapter of this roller skate brake assembly are detachably connected by screws. When the brake structure is worn and needs to be replaced, only the brake head part needs to be replaced, which is low-cost, energy-saving and environmentally friendly.

[0012] In addition, the brake assembly can adjust the protrusion height of the brake head to adapt to different types of skates by adjusting the screw depth between the adapter and the skate sole. Attached Figure Description

[0025] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:

[0026] Example 1

[0027] See appendix Figure 3-9 A brake assembly for roller skates includes a brake head 1, an adapter 2, and a screw 3 for connecting the brake head 1 and the adapter 2.

[0028] The adapter 2 includes a cylindrical portion 21 and a brim portion 22; the brim portion 22 is formed at one end of the cylindrical portion 21 and has a diameter larger than that of the cylindrical portion 21; the adapter 2 has a threaded hole 23 penetrating the brim portion 22 and the cylindrical portion 21; the threaded hole 23 is used for connecting the brake head 1; the cylindrical portion 21 has external threads for screwing into a nut 4 installed on the sole of the skate. In this embodiment, the threaded hole 23 is coaxial with the cylindrical portion 21.

[0029] The brake head 1 is provided with a connecting hole 11. The brake head 1 abuts against the cap edge 22 of the adapter 2. The screw 3 passes through the connecting hole 11 and is screwed into the threaded hole 23.

[0030] The combined roller skate brake assembly of this technical solution can replace the existing one-piece brake head and be used with roller skates. The brake head 1 and the adapter 2 of this roller skate brake assembly are detachably connected by screws 3. When the brake structure is worn and needs to be replaced, only the brake head part needs to be replaced, which is low-cost, energy-saving and environmentally friendly.

[0031] In addition, the brake assembly can adjust the protrusion height of the brake head by adjusting the screw depth between the adapter and the skate sole to adapt to different types of skates.

[0032] A limiting structure is provided between the brake head 1 and the adapter 2 to restrict the rotation of the brake head 1 relative to the adapter 2. The limiting structure includes a limiting protrusion 24 on the cap edge 22 of the adapter 2 and a limiting groove 12 on the brake head 1, wherein the limiting protrusion 24 falls into the limiting groove 12. Specifically, the brake head 1 includes a front end through which a screw 3 passes and a rear end through which the screw 3 passes, and the limiting groove 12 is located at the rear end of the brake head 1.

[0033] In this embodiment, the limiting protrusion 24 includes three protrusions, which are spaced apart around the axis of the threaded hole 23; the limiting groove 12 is provided with three corresponding limiting protrusions 24.

[0034] The connecting hole 11 includes a recessed portion 111 for inserting the screw 3 and accommodating the screw head 31, preventing the screw head 3 from being exposed and affecting the contact between the brake head 1 and the ground. The depth of the recessed portion 111 is greater than the thickness of the screw head 31, which can bring the screw 3 closer to the threaded hole 23, thereby shortening the required length of the screw 3. In this embodiment, the screw 3 is a Phillips head screw 3.

[0035] The brake head 1 is made of rubber.

[0036] Example 2

[0037] like Figure 10-13 As shown, an ice skate braking assembly, based on the above embodiment 1, further includes a nut 4 for mounting on the sole 5 of the ice skate for screwing onto the cylindrical portion 21 of the adapter 2; the nut 4 has an internal thread, and the external thread of the cylindrical portion 21 is screwed onto the internal thread of the nut 4.

[0038] During installation, first screw the adapter 2 to the nut 4 fixed to the sole 5 of the skate, then abut the brake head 1 against the cap edge 22 of the adapter 2 so that the limiting protrusion 24 falls into the limiting groove 12 of the brake head 1, and finally insert the screw 3 into the connecting hole 11 of the brake head 1 and screw the screw 3 into the threaded hole 23 of the adapter 2.

[0039] In use, the protruding height of the brake head 1 can be adjusted by adjusting the screw depth between the adapter 2 and the nut 4, such as... Figure 12 As shown.

[0040] Example 3

[0041] An adapter for use in the braking structure of roller skates, see adapter 2 in the above embodiment 1.

[0042] The adapter in this technical solution can be connected to the nut installed on the sole of the skate via the column part. The threaded hole of the adapter is for connecting to the brake head with a small screw, so that the skate can be equipped with the original one-piece brake head or replaced with a split brake head.

[0043] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
