Abstract

The invention discloses a single-hand-operated portable single lens bracket which is characterized by comprising a hook (1), an elastic limit ring (2) and a support rod (3). The hook (1) is hooked. The support rod (3) is formed by a downward extension part of the hook (1), and the hook (1) and the support rod (3) are integrally pressed. The support rod (3) extends down, and the tail end of the support rod (3) is bent up opposite to the hook (1) to allow for formation of a turned edge. The middle of the support rod (3) is recessed towards one side of the hook (1). The elastic limit ring (2) is fixed on the upper portion of the support rod (3) in a direction opposite to the hook (1). The single-hand-operated portable single lens bracket allows a single hand to change various single lenses conveniently and simply, and allows multiple lenses to be carried out for photographing. The single-hand-operated portable single lens bracket is simple in structure, easy to process and low in cost.

Description

The anti-camera lens carriage of the portable list of one-handed operation

Technical field

The invention belongs to photographic goods accessory field, relate to the anti-camera lens carriage of the portable list of a kind of one-handed operation, be a kind ofly often to use the anti-lens apparatus of a plurality of lists to carry out camera work at needs, and need often to change the portable equipment of camera lens.

Background technique

Along with growth in the living standard, a lot of people like single anti-photography, and slr camera and camera lens are also more and more used by the ordinary people.When photographing activity, owing to need often to change phtographic lens, and camera lens is all heavier relatively, and replacing is got up very inconvenient, wastes time.Now camera lens bag is more common, but it is as carrying bag tool, and the person that is not suitable for the camera work or fan's door are changed camera lens in the open air fast.The present invention is directed to this characteristics, designed a carriage that can hang over the portable quick replacing camera lens on belt or other backpack strips, can satisfy the quick replacing of a plurality of camera lenses, and one hand just can be operated, very convenient when going out to photograph, be fit to being used in combination of a plurality of camera lenses.Efficient and the quality of photography have been improved.

The most of knapsack for the dress camera lens of existing product of the same type, photography is particular about and is captured, chance and time are very important, and existing knapsack need be put into knapsack on the ground out of doors the time, and then open, change camera lens again, the camera lens that changes is contained in the bag again, wastes a lot of times like this, the best opportunity that may photograph has not just had, and when needs are changed frequently, more apparent very inconvenient and trouble.

Summary of the invention

The object of the present invention is to provide the anti-camera lens carriage of the portable list of a kind of one-handed operation, realize changing fast the effect that camera lens and portable a plurality of camera lens are gone out.

The technical solution that realizes the object of the invention is: the anti-camera lens carriage of the portable list of a kind of one-handed operation comprises hook, elasticity position limit cycle and pressure pin three parts.

The hook formation that hook is made by elastic plate is that the main load-bearing member of total is used for hanging in supporters such as belts.

Link up with downwards that the extension is pressure pin, both are one, do not cut apart.Pressure pin elongation downwards is about 45mm-70mm, and its end forms flange to turning up with the hook opposite direction, gives camera lens with constraint in vertical, holds camera lens, and it can not dropped.The middle part of pressure pin is left the space that holds to hook one side depression in order to the part of giving the camera lens different radii.

Pressure pin upside, hook are fixed flexible position limit cycle in the other direction.The elasticity position limit cycle is divided into two-layer, outer ring and inner ring.Outer ring and inner ring are one, and be big and have certain rigidity sheet material to make by elasticity coefficient.The outer ring is extended outward by pressure pin upper half part both sides and forms circular arc, but does not seal, its two terminal middle bayonet socket more smaller than diameter of lens that leave.The outer ring is terminal continues inside reflexed, forms the equidistant circular arc with its concentric, i.e. inner ring, and the inner ring radius is slightly less than the camera lens radius, is slightly larger than the bayonet socket size.The inner ring end does not seal and closes up, and is leaving free end near the pressure pin place.

During use, by hook total is hung on the belt earlier, again camera lens is pushed to bayonet socket is inner.Because outer ring and inner ring are elastic material, when bayonet socket receives that the camera lens more bigger than its radius pushes, whole elasticity position limit cycle generation deformation, it is big that the bayonet socket size becomes, and camera lens is pushed.After camera lens entered, deformation was recovered in the outer ring, and the reduction of bayonet socket size can outwards not dropped camera lens.Inner ring does not recover deformation fully, and the camera lens double team is lived, and it can not rocked.Camera lens is held by pressure pin under the effect of gravity then.The inverted sequence operation gets final product during camera switching.

The present invention compared with prior art, its remarkable advantage: can change the anti-camera lens of various lists by convenient and simple one hand, and the photography of can portable a plurality of camera lenses going out.Simple in structure, processing easily, cost is low, has the excellent popularization prospect.

Embodiment

Below in conjunction with accompanying drawing the present invention is described in further detail.

The anti-camera lens carriage of the portable list of a kind of one-handed operation comprises hook 1, elasticity position limit cycle 2 and pressure pin 3 three parts; The hook formation that hook 1 is made by the Thin Elastic corrosion resistant plate is that the main load-bearing member of total is used for hanging in belt 5 supporters such as grade; Hook 1 extension downwards is pressure pin 3, and both form in the one compacting; Pressure pin 3 elongation downwards is about 55mm, and its end forms flange to turning up with hook 1 opposite direction, gives camera lens with constraint in vertical, holds camera lens, and it can not dropped; The middle part of pressure pin 3 is left the space that holds to hook 1 one sides depression in order to the part of giving the camera lens different radii; Pressure pin 3 upsides, hook 1 is fixed flexible position limit cycle 2 in the other direction; Elasticity position limit cycle 2 is divided into outer ring 21 and inner ring 22; Outer ring 21 is one with inner ring 22, makes by the Thin Elastic corrosion resistant plate; Outer ring 21 is fixed on pressure pin 3 upper half part, extends outward the formation circular arc from both sides, but does not seal, its two terminal middle bayonet socket 23 more smaller than diameter of lens that leave; The inside reflexed of outer ring 21 terminal continuation, the equidistant circular arc of formation and its concentric, namely inner ring 22, and the inner ring radius is slightly less than the camera lens radius, is slightly larger than bayonet socket 23 sizes; Inner ring 22 ends do not seal and close up, and are leaving free end near pressure pin 3 places; During use, by linking up with 1 total hung on the belt 5 earlier, again with camera lens to bayonet socket 23 inner pushings; Because outer ring 21 and inner ring 22 are elastic material, when bayonet socket 23 received that the camera lens more bigger than its radius pushes, deformation took place in whole elasticity position limit cycle 2, and it is big that bayonet socket 23 sizes become, and camera lens is pushed; After camera lens entered, deformation was recovered in outer ring 21, and the reduction of bayonet socket 23 sizes can outwards not dropped camera lens; Inner ring 22 does not recover deformation fully, and the camera lens double team is lived, and it can not rocked; Camera lens is held by pressure pin 3 under the effect of gravity then; The inverted sequence operation gets final product during camera switching.

Above-described embodiment does not limit the present invention in any way, and every employing is equal to replaces or technological scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
