Abstract
A canvas clamping device relates to the technical field of clamps and solves the technical problem of poor reliability of an existing clamp. The clamping device comprises an upper clamping plate and a lower clamping plate, single faces of the upper clamping plate and the lower clamping plate are laminated in the opposite direction, single edges of the upper clamping plate and the lower clamping plate are pivoted through a pivot shaft, two spiral springs are sleeved on the pivot shaft, one end of each spiral spring tightly butts against the upper clamping plate, and the other end of each spiral spring tightly butts against the lower clamping plate. The canvas clamping device is characterized in that a plurality of biting teeth protruding towards the lower clamping plate are arranged on a plate face of the upper clamping plate and facing to one side of the lower clamping plate. The canvas clamping device is suitable for clamping canvas articles.
Description
Technical field
The utility model relates to clamp technology, particularly relates to a kind of technology of painting canvas clamping device.
Background technology
A lot of advertising media all show ad content through the advertisement painting canvas being posted in the mode of showing on the drawing board.
The advertisement painting canvas is posted in the mode of showing on the drawing board mainly contains following several kinds:
1) utilize adhesive tape or glue that the advertisement painting canvas is sticked on and show on the drawing board, this mode can be posted in the advertisement painting canvas reliably shows on the drawing board, but is difficult for taking off after having puted up, and changes and shows that painting canvas is very inconvenient;
2) utilize anchor clamps that the advertisement poster cloth holder is being showed on the drawing board; This mode is changed and is showed that painting canvas is very convenient; But, existing anchor clamps grasp the advertisement painting canvas because all being edges of boards through last lower plate; Its clamping reliability is relatively poor, and the advertisement painting canvas is deviate from between last lower plate easily, causes the advertisement painting canvas from showing that drawing board drops easily.
The utility model content
To the defective that exists in the above-mentioned prior art, the utility model technical problem to be solved provides a kind of painting canvas clamping device of clamping good reliability.
In order to solve the problems of the technologies described above, a kind of painting canvas clamping device that the utility model provided comprises train wheel bridge, lower plate; Said train wheel bridge and lower plate single face subtend are fitted; And train wheel bridge and lower plate are arranged with two helical springs through the monolateral pivot joint of a pivot on the said pivot, each helical spring end is tight against train wheel bridge; The other end is tight against lower plate, it is characterized in that:
Said train wheel bridge is provided with towards the outstanding a plurality of teeth of stinging of lower plate towards the plate face of lower plate one side.
Further, in each side of said train wheel bridge, a side that articulates with lower plate is the pivot joint limit, is positioned at its lateral edges that articulates the limit offside towards the oblique bending of the direction that deviates from lower plate, constitutes the train wheel bridge kink.
Further, said lower plate is provided with a plurality of installing holes.
The painting canvas clamping device that the utility model provides; Because train wheel bridge is provided with towards the outstanding a plurality of teeth of stinging of lower plate towards the plate face of lower plate one side; Can realize multiple spot clamping through respectively stinging tooth to clamping painting canvas hold assembly; Have the clamping high reliability features, the advertisement painting canvas of clamping is not easy between last lower plate, to deviate from, and also is not easy from showing that drawing board drops.
Description of drawings
Fig. 1 is the main TV structure sketch map of the painting canvas clamping device of the utility model embodiment;
Fig. 2 is the side-looking structural representation of the painting canvas clamping device of the utility model embodiment.
The specific embodiment
Embodiment to the utility model describes in further detail below in conjunction with description of drawings, but present embodiment is not limited to the utility model, and analog structure of every employing the utility model and similar variation thereof all should be listed the protection domain of the utility model in.
Like Fig. 1-shown in Figure 2, a kind of painting canvas clamping device that the utility model embodiment is provided comprises train wheel bridge 1, lower plate 2; Said train wheel bridge 1 is fitted with lower plate 2 single face subtends; And train wheel bridge 1 and the 3 monolateral pivot joints of lower plate 2 warps one pivot are arranged with two helical springs 4 on the said pivot 3, an end of each helical spring 4 is tight against train wheel bridge 1; The other end is tight against lower plate 2, it is characterized in that:
Said train wheel bridge 1 is provided with towards the outstanding a plurality of teeth 5 of stinging of lower plate towards the plate face of lower plate 2 one sides.
Among the utility model embodiment, in each side of said train wheel bridge 1, a side that articulates with lower plate 2 is the pivot joint limit, is positioned at its lateral edges that articulates the limit offside towards the oblique bending of the direction that deviates from lower plate 2, constitutes train wheel bridge kink 7.
Among the utility model embodiment, said lower plate is provided with four installing holes.
The utility model embodiment can a plurality ofly be used; Earlier be used to put up the painting canvas clamping device that a plurality of the utility model embodiment are installed on the drawing board of painting canvas during use, each painting canvas clamping device all is fixed on lower plate on the drawing board through four installing holes on the lower plate;
During each painting canvas clamping device clamping painting canvas,, make train wheel bridge overcome two helical spring elastic force earlier to the train wheel bridge kink application of force; Pivot towards deviating from the lower plate direction; Make the train wheel bridge and the subtend face of lower plate separate, then painting canvas is treated that clamping part inserts between the subtend face of train wheel bridge and lower plate, and then remove the power that is applied to the train wheel bridge kink; Train wheel bridge promptly pivots towards the lower plate direction under two helical spring elastic force effects; Make train wheel bridge on lower plate side plate face, sting the tooth painting canvas that links closely, thereby painting canvas is clamped between train wheel bridge and the lower plate, painting canvas is posted on the drawing board reliably.
Claims (3)
1. painting canvas clamping device; Comprise train wheel bridge, lower plate, said train wheel bridge and lower plate single face subtend are fitted, and train wheel bridge and the monolateral pivot joint of lower plate warp one pivot; Be arranged with two helical springs on the said pivot; Each helical spring end is tight against train wheel bridge, and the other end is tight against lower plate, it is characterized in that:
Said train wheel bridge is provided with towards the outstanding a plurality of teeth of stinging of lower plate towards the plate face of lower plate one side.
2. painting canvas clamping device according to claim 1; It is characterized in that: in each side of said train wheel bridge; A side that articulates with lower plate is the pivot joint limit, is positioned at its lateral edges that articulates the limit offside towards the oblique bending of the direction that deviates from lower plate, constitutes the train wheel bridge kink.
