Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1, for the utility model discloses a from embodiment of frame of taking cloth straining function, including frame 10, equipment round pin 20, clamping part 30 and taut portion 40, a frame is constituteed to a plurality of frames 10, and adjacent frame 10 connects through equipment round pin 20, consequently frame 10 both ends are provided with concatenation angle 11, be equipped with pinhole 12 in the concatenation angle 11, it is right that equipment round pin 20 passes through pinhole 12 frame 10 splices, in this embodiment, concatenation angle 11 is 45 jiaos to can utilize four frames 10 to splice into the rectangle frame, simultaneously equipment round pin 20 is 90 straight angle round pin, and the both sides of equipment round pin 20 insert respectively in the concatenation angle 11 of two adjacent frames 10, although can not guarantee the compactness of frame 10 connection this moment, can guarantee that frame 10 connects as complete quadrangle. Further, the tensioning portion 40 is rotatably connected to the back of the frame 10, so that the tensioning portion 40 can rotate around a connection point of the tensioning portion 40 and the frame 10, the clamping portion 30 is hinged to the middle of the tensioning portion 40, at this time, when the tensioning portion 40 rotates, the clamping portion 30 can be driven to move for a certain distance, specifically, the tensioning portion 40 rotates towards the clamping portion 30 and pushes the clamping portion 30 towards the inner side of the frame 10, at this time, the clamping portion 30 clamps the canvas in a loose state, then the tensioning portion 40 rotates in a reverse direction and pulls the clamping portion 30 towards the outer side of the frame 10, in the pulling process, the canvas is gradually tightened, after the frame 10 on four sides performs the operation, the canvas is completely tightened on the picture frame, meanwhile, the frame 10 is also provided with the tensioning limiting portion 50, the tensioning portion 40 drives the canvas to be limited by the tensioning limiting portion 50 after being tightened, and ensures that the canvas keeps in a tight state, in this state, since the four frames 10 of the picture frame are assembled and formed under the positioning of the assembling pins 20, the four frames 10 are simultaneously tensioned inwards by the tension force of the canvas, so that the frames 10 are not loosened, i.e. the canvas is tensioned and the frame is also fastened. Simple structure, simple to operate has saved the cost of inside casing to spare part mode transportation has practiced thrift the cost of transportation, and easily change the canvas, has improved the adaptability of frame.

Referring to fig. 2, which is the structural side view of the frame 10 of the present invention, in this embodiment, the back of the frame 10 is provided with a slot 13, the cross section of the slot 13 is preferably arc-shaped, the tensioning portion 40 includes a tension rod 41, one end of the tension rod 41 is connected with a cylindrical position-limiting part 42, the position-limiting part 42 is inserted into the slot 13, and the tension rod 41 is extended from the arc-shaped opening. The tightening rod 41 can rotate in the range of the arc-shaped opening, the tightening of the tightening rod 41 to the clamping part 30 is not affected, meanwhile, the tightening rod 41 can be inserted into the clamping groove 13 in a proper assembling step according to the structure, on one hand, the position and the quantity of the tightening rod 41 can be conveniently adjusted as required, on the other hand, the clamping part 30 can be enabled to insert the tightening part 40 into the frame 10 from the clamping groove 13 after the clamping of the canvas is completed, and the clamping of the canvas is facilitated. Furthermore, a hook 43 is disposed in the middle of the tightening rod 41, and a bayonet 31 engaged with the hook 43 is disposed on one side of the clamping portion 30. The clamping part 30 is convenient to be separated from the tensioning part 40, and the canvas is further convenient to be clamped.

Because the canvas is planar structure, in this embodiment, clamping part 30 adopts upper plate 32 and 33 formula structures of lower plate, adopts the mode of large tracts of land centre gripping to press from both sides tight the canvas, and the canvas is arranged in between upper plate 32 and the lower plate 33 after, upper plate 32 and lower plate 33 pass through locking mechanism and lock. For the realization to the comprehensive clamp of canvas side tightly, punch holder 32 and lower plate 33 with the interior limit of frame 10 is isometric, makes the canvas side can all be by the centre gripping, simultaneously locking mechanism is provided with a plurality of along its length direction, guarantees the clamp of canvas tightly. In this embodiment, for the convenient clamping to the canvas that realizes, locking mechanism includes spacing post 34 and cam 35, spacing post 34 one end is spacing head, spacing post 34 other end is for passing the free end of punch holder 32 and lower plate 33, cam 35 is connected with this free end rotation through the pin. When the apparatus is in the non-operating state, the small diameter side of the cam 35 abuts against the clamp plate, the canvas is placed between the upper clamp plate 32 and the lower clamp plate 33, and then the cam 35 is rotated to bring the large diameter side of the cam 35 into abutment against the clamp plate to clamp the canvas, and the cam 35 at this time also forms a dead point structure, and the clamped state of the clamp plate cannot be released without artificially rotating the cam 35. The clamping of the canvas can be done by just performing the operation of rotating the cam 35. And the opposite surfaces of the upper clamping plate 32 and the lower clamping plate 33 are provided with mutually meshed anti-slip convex ribs 36, so that the canvas is further prevented from being separated from the clamping of the upper clamping plate 33 and the lower clamping plate 33 under the action of the tightening force. In other embodiments of the present invention, the clamping of the upper and lower clamping plates 33 can be realized by other methods such as fasteners, which are not described herein again.

Referring to fig. 3, after the canvas is clamped, the clamping portion 30 is pulled by the tensioning portion 40 towards the outer edge of the frame 10, and under the condition that the four edges of the canvas are pulled outwards, the canvas is tensioned, and at this time, the tensioning portion 40 needs to be limited to prevent the canvas from returning. In this embodiment, the position is limited by a tightening limiting portion 50, and the tightening limiting portion 50 includes a plurality of limiting grooves 51 arranged along the length direction of the frame 10. The tensioning rod 41 tensions the canvas and then inserts the canvas into the corresponding limiting groove 51, and the limiting groove 51 limits the rotation of the tensioning rod 41, so that the position of the clamping part 30 is determined, and the canvas is tensioned in different degrees. Further, because the tightening rod 41 is not easily inserted into the limiting groove 51, a plurality of limiting plates 52 are slidably disposed in the limiting groove 51. The tightening rod 41 firstly rotates to the position for tightening the canvas, and then the limiting plate 52 in the corresponding limiting groove 51 is moved to enable the tightening rod 41 to be in the position for blocking the tightening rod 41, so that the tightening rod 41 is prevented from rotating, and the tightening rod 41 is limited. I.e. to ensure that the canvas is always in a taut state.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
