Stop and stop the structure-improved of castor

Technical field

The utility model is a kind of Castor structure, and espespecially a kind of have an only castor improvement knot of effect of well stoppingStructure.

Background technology

Along with the epoch are progressive, general common people's consumption habit also changes thereupon, conditional from the early stage business hoursGrocery store, just can see the convenience store of a whole day business to modern entrance to a lane, then to measure valency processed,Shopping large-scale sales field easily, and according to the kenel difference in shop own, requiredly when shopping is used for filling articleApparatus is also different, and it is main that bantam shop provides client's hand basket, and large-scale sales field is can fill pushing away of a lot of articleChe Weizhu.

Because innerland, large-scale sales field is enough large, Shopping Space and ornaments relative comfort compared with bantam shop are wideSpacious, therefore spacious shopping aisle can be provided, the use of go-cart implementation is provided, again, peddle large-scale sales fieldGoods is multifarious, and product item and quantity are more and more, and dealer often distinguishes floor by goods and puts, and causes clientNeed to push away go-cart and take on Escalator downstairs, go-cart meeting is because Escalator angle of inclination, and causes before go-cartRear slip, if accidentally, the client's that may wound accident, in view of this prior art all can be in go-cartCastor is provided with the only structure of stopping.

The castor of the prior art only structure of stopping, in castor arranged outside one stops of stopping, when castor sinks into EscalatorIn the ditch line of rabbet joint, outside stop stops with the friction of plural flute surfaces, produce on-slip power; Another prior art isOuter wheel diameter is greater than interior wheel diameter, when foreign steamer sinks into, in the Escalator ditch line of rabbet joint, inside to take turns and can rub with flute surfacesWipe, produce on-slip power.

But, above-mentioned two prior aries, though basic on-slip power is provided, or normal generation go-cart is in electricitySliding condition on staircase, not only causes user's inconvenience, therefore injury more may occur unexpected, and this practicality is newThe designer of type pays close attention to this problem for many years, and therefore through constantly research and improvement, proposition one has well stopsThe only castor structure-improved of effect.

Utility model content

Detailed description of the invention

Understand and realize the utility model for the ease of persons skilled in the art, now describing by reference to the accompanying drawings thisThe embodiment of utility model.

Refer to Fig. 1 to Figure 15, the utility model provides a kind of only structure-improved of castor of stopping, and comprises oneWheel seat 1, this wheel seat 1 is provided with articulated section 11, and this articulated section 11 is provided with perforation 12, and this wheel seat 1 is provided with holding section13, one stops 2 of stopping, this stops 2 of stopping is provided with body 21, neck 22 and butting section 23, and establish these body 21 bottom surfacesHave plural on-slip projection 211, this neck 22 is mounted on this holding section 13, and this butting section 23 is resisted against this engagingPortion's 13 end faces, and a wheel body 3, this wheel body 3 by the first foreign steamer 31, second foreign steamer 32 clampings one are interior takes turns 33 groupsBecome, this first foreign steamer 31, this second foreign steamer 32 are provided with docking section 311,321, and these interior wheel 33 internal diameters are greater than thisThese docking section 311 external diameters of the first foreign steamer 31, this interior wheel 33 is provided with plural on-slip groove 331, and this wheel body 3 is logicalCross screw 4 and nut 5 and be mounted on this articulated section 11.

Refer to Figure 16 and Figure 17, by said structure, establish structure-improved of the present utility model in go-cart group,When go-cart is in the time that level land is used, because the internal diameter of this interior wheel 33 is greater than outside this docking section 311 of this first foreign steamer 31Footpath, this interior wheel 33 can't contact with this stops 2 of stopping, and there is no the only effect of stopping, and this wheel body 3 is rolled smooth and easy,Again, in the time that user pushes this go-cart in this go-cart Special electric staircase wish downstairs, be positioned at outside thisOne foreign steamer 31 and this second foreign steamer 32 peripheries can be sticked in Escalator groove 6, and this interior wheel 33 is because holding up with this electricityLadder groove 6 end faces contact and jack-up, and this on-slip groove 331 of the plural number of this interior wheel 33 is closely sticked in this stops of stoppingThis on-slip projection 211 of 2 plural number, reaches the only effect of stopping, and this wheel body 3 cannot be rotated; By this outside firstWheel 31 and this second foreign steamer 32 are sticked in this Escalator groove 6, and the formation first step is stopped and stopped effect, then profitWith this Escalator groove 6 by these interior wheel 33 jack-up, and then this on-slip groove of plural number 331 that makes this interior wheel 33 with shouldThis on-slip projection 211 of plural number of stops 2 stopped closely engages, and forms the second step only effect of stopping, and stops by this two stepOnly function, what make that this go-cart can be firm stands on this Escalator, does not move forward and backward easily, reaches real peaceComplete and the only effect of stopping.

Again, the utility model is because connecing with this go-cart group, and this wheel seat 1 is further provided with steering bearing 7, can deal withUser's demand, moves this go-cart rotation to direction needing; These interior wheel 33 inside are further provided with steel ring332, strengthen this interior wheel 33 integral rigidity, reach the best only effect of stopping; This first foreign steamer 31 and this secondForeign steamer 32 is further provided with 312,322 groups of recess 312,322, two this recesses and is provided with bearing 8 and dust cap 9,Can make this articulated section 11 and these wheel body 3 contact positions rotate smooth and easy more flexibly; This perforation 12 is further provided with groove121, this screw 4 is further provided with protuberance 41, makes this screw 4 more closely be locked on this articulated section with this nut 5On 11.

Separately, due to the prior art only scarce capacity of stopping, and be difficult for detecting immediately the castor degree of wear, when existingWhen the castor of technology is contacted with the comb plate of this Escalator terminal, can slide backward not because of on-slip power, orThe only ability inequality because the forward and backward castor of go-cart is stopped, causes go-cart to be overturned, and makes user produce puzzlement, cannotSmoothly this go-cart is pushed away to this Escalator, and when the utility model is in the time contacting this comb plate, due to the only energy of stoppingPower is better, can make this go-cart can not slide backward by the reaction force when contacting with this comb plate, userMore can be smoothly push away this Escalator from being about to this go-cart, again, because this go-cart is according to environment for use difference, palpusOn different road surfaces, carry out, if surface gathered water, this on-slip groove 331 of the plural number of this interior wheel 33 has splendidWater-sprinkling can not skid this go-cart in the time carrying out.

Generally, no matter prior art is in the castor side setting stops of stopping, or wheel and this electricity in utilizingStaircase trench contact produces friction on-slip power, is all to utilize plane Skidproof structure to reach and stop to stop effect, and this realityWith novel be protruding by this on-slip groove 331 of plural number of this interior wheel 33 and this on-slip of plural number of this stops 2 of stoppingThe closely three-dimensional Skidproof structure of engaging of piece 211, produces best anti-slip effect.

Although described the utility model by embodiment, those of ordinary skill in the art know, not de-In the situation of spirit of the present utility model and essence, just can make the utility model have many distortion and variation,Scope of the present utility model is limited to the appended claims.
