Abstract

The utility model relates to a wheel frame structure for roller skates, particularly a combined member which can be disassembled and assembled right and left. Staggered inserting tenons are mutually embedded on a fixing seat, and a plurality of screw bolts are used for supporting transverse stress. Due to the separated manufacture in left and right, axial and longitudinal reinforced ribs are arranged in the inside of the parallel wall to form netted stagger. The reinforcing ribs are surrounded around wheel shaft holes of the positioning wheel. Strength of the wheel shaft holes and the parallel wall is increased, and the assembly is convenient.

Description

The wheel for roller skates shelf structure

The utility model relates to a kind of wheel for roller skates shelf structure.

The wheel carrier structure of the straight line roller skate of commonly using is the design that a kind of formula that is formed in one is arranged, as shown in Figure 4, though it is simple for production, assembling rapidly, right its still is subject to the restriction of manufacturing technology and the misgivings of undercapacity arranged, when ice skate slide or jump etc. fast, its shoe rack main body must be born three-dimensional power, it is axial stress, lateral stress, longitudinal stress, wherein with the longitudinal stress maximum, because of in sliding, the gravity of health and the impact that is produced of jumping all vertically are passed to ground through parallel walls, so how to strengthen the overriding concern that longitudinal strength is design, and the method for strengthening intensity has two, one for increasing thickness, but this measure causes waste material, increase cost burden, make the user feel its heaviness, as for moulding the wheel carrier of making shape, because of the too thick meeting of thickness causes shrinking deformation, two for setting up reinforced ribs (as shown in Figure 4), so in using when stressed, and the stress meeting that it bore thereby concentrate on the flank junction, easily breakdown on the contrary, and it is,, in fact horizontal just so producer seldom makes axial rib with reinforcement because of the technical problem of vertical withdrawing pattern, axial stress also is less; Take a broad view of it, the product of commonly using are provided with at horizontal and axial reinforced ribs slightly dislikes less.

The purpose of this utility model is to provide a kind of wheel for roller skates shelf structure, the flank junction stress of its product of commonly using of forgoing is concentrated and the defective of fracture, member is simple, easy to assembly, and minimizing material cost, make that reinforced ribs directly depends on, dimpling is on the parallel walls medial surface, but still can bear its horizontal stroke, axle, vertical three-dimensional stress.

For reaching above-mentioned purpose, wheel carrier of the present utility model is made up of two parallel walls, its upper end is two chimeric holders, and wheel carrier bottom and be provided with axle hole, in order to the location wheel, wherein wheel carrier vertically is divided into halves, parallel walls is unified by per half one, and each parallel walls is provided with the two-layer strip in the holder end face can concavo-convex chimeric staggered plug tenon, and strip long then lower floor in upper strata is short, on the contrary the short then lower floor head in upper strata, the staggered plug tenon of two parallel walls is crisscross arranged, and symmetrical mutually in order to chimeric, and under two holders, set up two coupling holes, closed admittedly with bolt or rivet.

In addition, the utility model parallel walls interior sidewall surface is provided with axially, netted staggered reinforced ribs longitudinally, and around its axle hole also around reinforced ribs is set.

After adopting said structure, because of being provided with netted staggered reinforced ribs on the utility model parallel walls interior sidewall surface, be provided with several bolts between two parallel walls, the staggered plug tenon that adds on the upper fixed seat is chimeric mutually, and the ability that makes the utility model bear horizontal stroke, longitudinal axis three-dimensional stress strengthens; In addition, the utility model member is simple, and assembling is easy, and the cost of material is low.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a stereogram of the present utility model;

Fig. 2 is a three-dimensional exploded view of the present utility model;

Fig. 3 is an embodiment stereogram of the present utility model;

Fig. 4 is a sectional axonometric drawing of commonly using product.

At first see also Fig. 1, shown in 2, the utility model wheel carrier 2 is two groups of staggered plug tenon 25 mutual chimeric fixings that utilized its two holder 22 by the parallel walls 21 of two symmetries, and below two holders 22, set up two coupling holes 26, fasten reinforcement with bolt 4, cooperate four-wheel axis hole 27 to fasten four bolts, 5 location four-wheel 3 again and promptly finish present embodiment (scheming shown in Figure 3), wherein: the holder 22 of wheel carrier 2, the staggered plug tenon 25 of its end face be for the two-layer strip concavo-convex chimeric, strip long then lower floor in upper strata is short, otherwise the short then lower floor head in upper strata, so two sizes that concavo-convex length has that one is long and the other is short alternately arrange mutually, and chimeric holder 22 end faces of another desire and it is symmetrically in order to chimeric; In addition, except that staggered plug tenon 25, and be to strengthen it to bear the intensity of lateral stress, so below two holders 22, set up two coupling holes 26, be able to bolt 4 and fix two parallel walls 21, add four required bar axle center of bottom location wheel 3, equal to add that by staggered plug tenon 25 six roots of sensation bolt bears lateral stress, and lateral stress was just smaller originally, so take a broad view of the transverse strength design of the product of commonly using, design of the present utility model is more than sufficient already, reaches perfectly safe border.

In addition, the re-manufacturing technology aspect, general integrated wheel carrier 2, it is the technology that adopts vertical withdrawing pattern, right this has a shortcoming, promptly be difficult for setting up axial rib 23 with reinforcement at parallel walls 21 inwalls, and the utility model is taken two parallel walls 21 apart manufacturing, utilizes staggered plug tenon 25 chimeric again, can reach quick assembling, and netted reinforced ribs is set in parallel walls 21 inwalls, by axial rib 23, longitudinal rib 24 interconnected forming, and external carbuncle is evenly disperseed towards each reinforced ribs, make wheel carrier safer durable, and around arranging reinforced ribs, generation destroys cracked when passing to wheel carrier 2 with the impulsive force of avoiding bolt that wheel is subjected to around axle hole 27.

Claims

1, a kind of wheel for roller skates shelf structure, wherein wheel carrier is made up of two parallel walls, its upper end is two chimeric holders, and wheel carrier bottom and be provided with axle hole, in order to the location wheel, it is characterized by: wheel carrier vertically is divided into halves, per half one contains a parallel walls, and each parallel walls is provided with the concavo-convex chimeric staggered plug tenon of two-layer strip in the holder end face, strip long then lower floor in upper strata is short, on the contrary the short then lower floor head in upper strata, and the staggered plug tenon of two parallel walls is crisscross arranged, and symmetry is chimeric mutually, and sets up two coupling holes under two holders.
