Abstract
The utility model relates to a roller seat fixing structure of skates. A roller seat is connected with a pulley wheel by a screw bolt and is fixed by a screw cap, wherein, one end of the bolt body of the screw bolt is a hollow female thread; a tip body is extended from the cap portion of the screw cap; the tip body corresponding to the female thread of the screw bolt is provided with a male thread; the bolt body of the screw bolt is passed and connected with the roller seat and the pulley wheel and screwed with the hollow female thread of the screw bolt by the male thread of the bolt body; a solidly and tightly screwed shaft bolt can be formed.
Description
The utility model is a kind of wheel for roller skates seat holding structure, refers to a kind of wheel seat holding structure that the pivoted axle bolt of pulley is improved especially.
Be used for wearing the axle bolt of pivot pulley on the known ice skate wheel seat, as shown in Figure 3, be to comprise a bolt (A) and a nut (B), wherein, this bolt (A) is the circular gill fungus shape cap portion (A1) that at one end forms big footpath tool cross chase, extend a key than path (A2) by the lower surface of cap portion (A1) again, pin thread (A21) is held and be provided with to key (A2) in addition; And this nut (B) is a polygonal block, its center and tool one perforation (B1), and peritreme forms negative thread (B2); Again, wheel seat (C) is gone up the placement of relative pulley (D) to being provided with shrinkage pool (C1) by nut (B); Mat it, as shown in Figure 4, be embedded in the shrinkage pool (C1) this nut (B) fixing, wear with the key (A2) of bolt (A) again and tie in wheel seat (C) and pulley (D), make the pin thread (A21) of its end be screwed together in perforation (B1) negative thread (B2) of nut (B), causing pulley (D) serves as that axle can rotate smoothly with bolt (A); Bear a people total weight because of ice skate, its weight drops on again on this bolt (A) entirely, and the ice skate dress is slided the situation that collision is arranged often and is taken place, so causing, the shrinkage pool (C1) on this wheel seat (C) can cause distortion crooked, and order axle bolt off-centre, and nut (B) also easily pitches, and pulley (D) is broken away from, and is very dangerous; Because of bolt (A) is to establish pin thread (A21) in the end, make the external diameter of key (A2) reduce relatively in addition, promptly intensity reduces relatively, and easily causes bending, even fracture.
The purpose of this utility model is: a kind of wheel for roller skates seat holding structure is provided, refers to that especially a kind of can making screws togather more closely firmly, shrinkage pool is stressed evenly, the wheel for roller skates seat holding structure that difficult generation distorts.
Task of the present utility model is achieved in that the negative thread that utilizes bolt sky in key one end forms, and the negative thread of relative bolt is established the nut of the corresponding pin thread tip of tool body, use and to utilize this nut to close the interior empty negative thread of bolt after the key that makes bolt is worn knot wheel seat and pulley, closely screw togather and solid axle bolt and form one with the pin thread bolt of tip body.
Because adopt said structure, promptly negative thread is in the bigger bolt of diameter, has avoided the little pin thread in key end to be exposed to the outside, has strengthened bond strength to guarantee its safety firm, durable and the user.
Below with regard to detailed construction of the present utility model and cooperate graphic being described as follows with the assembling situation of wheel carrier, pulley:
Fig. 1 is a three-dimensional exploded view of the present utility model.
Fig. 2 is an assembled sectional view of the present utility model.
Fig. 3 is a structural representation of commonly using product.
Fig. 4 is an assembled sectional view of commonly using product.
At first see also Fig. 1, structure of the present utility model includes wheel seat (1), a bolt (2) and a nut (3) three parts, wherein:
Wheel seat (1) locates to be provided with pivot hole (11) in that pulley (4) is set, and corresponding pivot hole (11) forms circular shrinkage hole (12); Bolt (2) one ends form a cap portion (21), extend a key (22) by cap portion (21) again and form the hollow tube of tool negative thread (23) in other section of key (22); Nut (3) is the tip body (33) that is extended a tool pin thread (32) by cap portion (31).
As shown in Figure 2, pulley (4) is opposite to relative this pivot hole (11) in the wheel seat (1), key (22) with bolt (2) is placed through pivot hole (11) again, pulley (4), mat nut (3) passes circular shrinkage hole (12) with the tip body (33) of its tool pin thread (32) by other side pivot hole (11), negative thread (23) with bolt (2) key (22) screws togather again, and the cap portion (31) that makes nut (3) is embedded in circular shrinkage hole (12) and is closely against bolt (2) key (21) end fixing, simultaneously, the tip body (33) of this nut (3) is screwed together in the hollow tube of bolt (2) key (22), make this key (22) not because of hollow influences its intensity, firm to guarantee it, durable, also tie up user's safety.
Claims (1)
- A kind of wheel for roller skates seat holding structure is to utilize the key of a bolt to wear pivot wheel seat and pulley, and cooperates a nut and key to fix, and wherein this bolt is the cap portion in the big footpath of tool one, and extends a key by cap portion; It is characterized in that: bolt is the hollow tube that key one end forms tool negative thread in; Nut is that the cap end surface extends a tip body, and the negative thread of relative bolt hollow end forms pin thread on the tip external body.
