Abstract
A painting rolling canister is a major part for a portable advertisement painting container, the utility model discloses a painting rolling canister with automatic lock function, the utility model adopts a clockwork spring as an energy saving unit, the automatic lock function is provided by tightening the clockwork spring. When taking the painting roll from the case, the energy storage unit will not release, the painting change is very convenient. Comparing with painting rolling canisters known in the art, the utility model is very convenient and simple, the cooperation accuracy requirement is low and the production cost is less. The utility model is widely applicable to different housing materials, which is a value component for exhibition components.
Description
Affiliated technical field
The utility model relates to a kind of later-model exhibition apparatus parts.
Background technology
A kind of portable advertisement poster holder is arranged in the market, and a variety of although outward appearance has, its major part is exactly a volume scroll holder, a very big torsion spring is housed as energy-storage travelling wave tube in the volume scroll holder, by the torsion of torsion spring one width of cloth advertisement poster is rolled.Its shortcoming is that the torsion spring that screws can loosen moment in order to change picture the volume scroll holder when taking off from shell, and noise is frightful, bothers very much and will screw torsion spring again, and is extremely inconvenient.
The purpose of this utility model provides a kind of volume scroll holder that auto-lock function is arranged, and when this volume scroll holder was taken off from shell, energy-storage travelling wave tube can not release energy.It is very convenient to change picture.
Summary of the invention
The technical solution of the utility model is such: be with clockwork spring as energy-storage travelling wave tube, when screwing clockwork spring, by one group of click monodirectional locking, ratchet can have certain moving axially.Behind shell that the volume scroll holder is packed into, the polygon shaft on the shell is with the ratchet jacking, and pawl-and-gearing breaks away from, and the volume scroll holder can rotate in the enclosure, and the advertisement poster that is installed on it can freely pull out or roll.
The utility model is compared with existing volume scroll holder, and is easy to use, and parts are simpler, and quality of fit requires lower, and productive costs is not high, and is very wide to the applicability of different shells, is of great value exhibition apparatus parts.
Description of drawings
Fig. 1 is the volume scroll holder exploded view in the utility model.
Fig. 2 is the embodiment in the utility model.
With reference to accompanying drawing 1,2: cover A (1) top is cast with several ratchets (2), is equivalent to a ratchet.The ratchet that several pairings are arranged on the ratchet (3), its one is cast with helical teeth (12), passes the hole among the cover A (1), and the other end heads on spring (5), is placed in the axis hole in the going barrel (6), and certain moving axially can be arranged.(4) one on clockwork spring is fixed on seam (10) lining on the ratchet (3), and the other end is buckled in the lining, U-shaped hole (9) on going barrel (6) limit.Be fixed on of stack shell (7) after their assemblings, cover B (8) is fixed on the other end of stack shell (7).When inserting polygonal hole (16) clickwise of ratchet (3) lining with special key, because the effect of ratchet, clockwork spring only can not screw and can loosen this moment.Baffle plate (11) is enclosed within on the ratchet (3), and its effect is to prevent that clockwork spring (4) from blocking ratchet (3).
The specific embodiment
With reference to accompanying drawing 2: pack in the shell (13) when the volume scroll holder volume that screws clockwork spring being gone up advertisement poster (15), axle insertion axle sleeve (14) lining on the cover B (8), helical teeth (12) on the ratchet (3) and polygon shaft (17) are gone up the guiding of corresponding helical teeth by the inclined-plane, make polygonal hole (16) can entangle polygon shaft (17) smoothly, ratchet on the ratchet (3) and the ratchet (2) of casting on cover A (1) break away from, and the volume scroll holder just can rotate in the enclosure.Advertisement poster (15) thus can freely pull out or roll.When changing picture and will roll up scroll holder and take out in shell, spring (5) heads on ratchet (3) and moves axially, ratchet on the ratchet (3) and casting ratchet (2) engagement on cover A (1), and the volume scroll holder is in self-locking state again.Shell (13) etc. all is an ordinary skill, no longer describes in detail herein.
In the present embodiment, the external diameter of stack shell (7) is 40mm, makes with aluminum alloy.The specification of clockwork spring (4) is 0.20mm*22mm*3000mm, makes with the high-quality spring steel plate.Ratchet (2) is pressed circumference 12 five equilibriums, tooth depth 3mm, and polygonal hole (13) is a hexagon, casts with plastics.
Claims (3)
1. volume scroll holder that auto-lock function is arranged, it is characterized in that cover A (1) top is cast with ratchet (2), the ratchet that pairing is arranged on the ratchet (3), (3) holes of passing among the cover A (1) of ratchet, the other end heads on spring (5), be placed in the axis hole in the going barrel (6), (4) one on clockwork spring is fixed on seam (10) lining on the ratchet (3), the other end is buckled in the lining, U-shaped hole (9) on going barrel (6) limit, be fixed on of stack shell (7) after their assemblings, cover B (8) is fixed on the other end of stack shell (7).
2. a kind of volume scroll holder that auto-lock function is arranged according to claim 1 is characterized in that polygonal hole (16) is arranged on the ratchet (3).
3. a kind of volume scroll holder that auto-lock function is arranged according to claim 1 is characterized in that of ratchet (3) has helical teeth (12).
