Description

Foldable bag support frame

Technical Field

The utility model relates to an articles for daily use, more specifically say, the utility model relates to a collapsible sack support frame for sack such as disposal bag, storing bag props mouth and supports, and article are deposited to the convenient to use sack.

Background

At present, no special tool for opening and supporting the bag exists in the market, the using scene is similar to that of the garbage can in which the garbage bag is sleeved, and the garbage can has the defects that the requirement on the size of the garbage bag is strict, the special garbage bag is generally used, and the garbage can is not convenient to clean; the market also has the support of hanging the disposal bag, but it can only use the disposal bag of taking the handle, can not strut the disposal bag completely moreover, also has great restriction to the disposal bag size scope. Along with the national requirement on garbage classification treatment, the use amount of the garbage can and the garbage bags is increased, and meanwhile, the plastic bags for shopping cannot be used for placing garbage in the garbage can due to different sizes, so that resource waste is caused.

Disclosure of Invention

It is an object of the present invention to solve at least the above problems and to provide at least the advantages which will be described later.

In order to realize according to the utility model discloses these purposes and other advantages, provide a collapsible sack support frame, specifically say exactly can prop the shelf of sack, richen the use scene of sack and improve the result of use of sack.

The utility model discloses at least, include following beneficial effect:

the utility model discloses a secondary usage rate and the result of use of sack are being improved to reduce wasting of resources and environmental pollution, the plastic bag use amount is very big in people's life, and the vast majority uses just to be abandoned after once, and the lower leading cause of rate of utilization is that sack size specification differs, is not convenient for put in the garbage bin and is done the disposal bag secondary and use, and the garbage bin is dirty also not convenient for wash. The utility model discloses just from above considering, through installing at folding epaxial belleville spring, make collapsible sack support frame have beta structure and rotation damping function, can keep collapsible sack support frame structure unchangeable when no exogenic action to have certain holding power, with the opening size of the collapsible sack support frame of free adjustment, the sack that adapts to the installation equidimension uses. The sack is unsettled and cover collapsible sack support frame upside frame after the installation, can discover at the very first time that the sack has or not to lose hourglass, and simple structure also is more convenient for wash, and the fungible traditional garbage bin also can be used as the appurtenance of bagging-off simultaneously, but collapsible structure also carries the storage more conveniently.

The utility model provides a collapsible bag support frame, overall structure includes: the foldable bag support frame is characterized in that the foldable bag support frame is in a cross shape in an opening state and is in a 1-shaped shape in a folding state, the relative rotating friction force of the inner support and the outer support is increased through the pressure exerted by a belleville spring on the folding shaft, the folding damping of the foldable bag support frame is formed, the foldable bag support frame has the holding force for keeping the opening and closing angle, when a bag is installed, the opening of the foldable bag support frame is larger than that of the bag, one side of the bag is firstly overturned and hung on the support on one side, the opening of the foldable bag support frame is compressed, the other side of the bag is overturned and sleeved on the support on the other side of the foldable bag support frame, the bag opening is outwards supported under the combined action of the damping of the foldable bag support frame and the frame deformation resilience, and the friction force between the bag and the foldable bag support frame is increased to prevent the bag from falling off when articles are supported.

The corner of inner support and outer support is the lobe structure, and when the sack overturns to hang on collapsible sack support frame, the lobe part makes sack distortion, plays the effect of shrink sack, improves the firmness that the sack hung, avoids bearing the dress heavy object to make sack and collapsible sack support frame break away from, only need during folding with inner support and outer support around folding the axle rotate fold together can, can realize folding fast open, not the time spent can with the utility model discloses hang after folding and receive the storage, also portable uses in the open air.

Other advantages, objects, and features of the invention will be set forth in part in the description which follows.
