Description
Technical field
The utility model relates to a kind of perambulator, is specifically related to a kind of folding umbrella-type pram.
Background technology
Children trolley is one of accessory appliances of infant's outdoor activities, can be divided into portable (claiming umbrella-type again) go-cart, light go-cart, two-seater go-cart (using for twins family) and common go-cart.Wherein the umbrella-type go-cart is collapsible, and volume after folding is less, and is easy to carry, thereby use is comparatively general, is a vehicle that most of mothers select.
Usually, umbrella handle vehicle comprises pair of side brackets, the folding rear pole that is connected with the rear portion of described side stand, the folding bottom supporting rod that is connected with the bottom of described side stand, described side stand comprise push rod, with the front-wheel support of the leading section pivotal joint of push rod, with the rear wheel support of the leading section pivotal joint of described push rod, the end of described front-wheel support and after poppet is respectively equipped with roller; Be connected with the left and right side grab rail respectively on described left and right side support, the front end of side handrail bar can be installed preceding grab rail, also service plate can be installed.
In the prior art, the left and right side grab rail all is to draw from the side stand push rod of respective side, and the end and the side stand of grab rail are rotationally connected, and when folding, grab rail can be to the inboard upset of vehicle body, to reduce volume.But the handrail of the connection mode that this is common is drawn by push rod, need on grab rail, draw a strut member and be fixed in front-wheel support, because this handrail is by drawing on the push rod, thus can not hidden this strut member, influence its vehicle frame outward appearance.
Summary of the invention
The utility model purpose provides a kind of preceding handrail and the fixing folding umbrella-type pram of vehicle frame, uses this structure, and the foldable structure of grab rail is more simple, and moulding is more attractive in appearance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of folding umbrella-type pram, comprise pair of side brackets, the rear wheel support that is connected with the rear portion of described side stand, the bottom bar that this rear wheel support is connected with the bottom of described side stand, described side stand comprises push rod, the front-wheel support that is rotationally connected with the leading section of push rod, be hinged with cushion rod between described front-wheel support and the rear wheel support, the end of described front-wheel support and rear wheel support is respectively equipped with roller, a left side, be respectively equipped with a side handrail bar between the described front-wheel support of right both sides and the described cushion rod respective side, the bottom of described side handrail bar and described cushion rod are hinged, the described side handrail bar at nearly described front-wheel support place supports iron plate through one and is connected with described front-wheel support, the two ends of this support iron plate are articulated in respectively on described side handrail bar and the described front-wheel support, constitute four-bar linkage.
In the technique scheme, described front-wheel support is divided into left and right side, between corresponding each side and the described cushion rod side handrail bar is set, with the side handrail bar connection mode of a side wherein is example, described side handrail bar bottom and described cushion rod are hinged, the other end nearby wheel support place one support iron plate is connected with front-wheel support, and the two ends of supporting iron plate are connected with front-wheel support and side handrail bar in the pivotally attached mode, thereby make cushion rod, front-wheel support, support iron plate and side handrail bar constitute four-bar linkage.Structure principle according to four-bar linkage, distance between four binding sites is fixing, thereby in use, under open mode, the angle that the side handrail bar rotates is subjected to the restriction of distance between node, realize the location of offside grab rail with this, have only the front-wheel support of working as and cushion rod inwardly to fold by binding site, thereby the distance between dwindling, according to four-bar linkage structure, support iron plate two ends binding site and rotate, the side handrail bar can inwardly fold, and makes up principle apart from unmodified four connecting rods thereby coincide between the binding site.So, utilize the characteristic offside grab rail of the four-bar linkage location of overturning, realize returning the vehicle to the garage and knock off purpose.
In the technique scheme, also comprise grab rail before, the two ends of this preceding grab rail flexibly connect with the described side handrail boom end of respective side respectively.Described flexible connection can be the engaging inserting mode, or other detouchable connection modes in the prior art, whether installs as required for the user, and is flexible and convenient to use.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, because the side handrail bar directly is connected with cushion rod in the utility model, with support iron plate through one between the front-wheel support and be connected, hinged in conjunction with cushion rod and front-wheel support, constitute four-bar linkage, utilize the structure principle of four-bar linkage, limit the position of side handrail bar under the vehicle frame open mode, have only when changing the position between front-wheel support and the cushion rod, break the location between the binding site, for meeting the immutable principle of distance between points, supporting the iron plate two ends rotates, the side handrail bar can be realized collapse state, with the single-ended location of replacement to live, four-bar linkage location, has changed stressed position, stability is stronger, and firmness is also higher;
2, the connection mode of side handrail bar and front-wheel support is more oversimplified, and after the support iron plate is hidden in front-wheel support, has beautified body frame structure for automotive;
3, and arranged on left and right sides side handrail bar and preceding handrail flexibly connect, and handrail before can installing or remove according to customer requirement uses more flexible, convenient.
