Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses a granny rag lamp house, including box 1, box 1 includes bottom plate 11 and frame material 12, frame material 12 sets up around bottom plate 11, inner chamber 13 has all been left in every frame material 12, articulated being provided with on the frame material 12 is used for coveing the gland 121 of inner chamber 13, gland 121 and frame material 12 articulated position are provided with the coil spring (not drawn in the picture), when the coil spring is in normal condition, gland 121 shields inner chamber 13, when rotating gland 121 and making gland 121 not when sheltering from inner chamber 13, the coil spring is in deformation state.

Referring to fig. 1 and 2, the canvas 2 is detachably arranged in the frame material 12, a first clamping plate 131 and a second clamping plate 132 which are used for clamping the canvas 2 are arranged in the inner cavity 13, the first clamping plate 131 and the second clamping plate 132 are parallel to each other, the first clamping plate 131 is slidably arranged in the inner cavity 13, the second clamping plate 132 is fixedly arranged in the inner cavity 13, and when the canvas 2 is required to be fixed, the canvas 2 is placed between the first clamping plate 131 and the second clamping plate 132.

Referring to fig. 4 and 5, a guide part for limiting the first clamping plate 131 to slide directionally is arranged in the inner cavity 13, the guide part includes a guide bar 135, the guide bar 135 is arranged on the inner wall of the inner cavity 13, the length direction of the guide bar 135 is perpendicular to the first clamping plate 131 and the second clamping plate 132, a guide groove 1311 is formed in the first clamping plate 131, and the guide groove 1311 is matched with the guide bar 135.

Referring to fig. 4 and 5, a driving member for driving the first clamping plate 131 to move toward the second clamping plate 132 is disposed in the inner cavity 13, the driving member includes a threaded rod 133 and a handle 134, the threaded rod 133 vertically penetrates through the first clamping plate 131, one end of the threaded rod 133 penetrating through the first clamping plate 131 is rotatably disposed on the second clamping plate 132, and the handle 134 is disposed on one end of the threaded rod 133 far away from the second clamping plate 132.

Referring to fig. 5, the rubber layer 136 is disposed on the wall of the first clamping plate 131 opposite to the second clamping plate 132, and the rubber layer 136 is provided with anti-slip patterns 1361.

Referring to fig. 2 and 3, a pressing member 1211 is disposed at a position where the pressing cover 121 abuts against the frame 12, the abutting member is made of rubber, and an anti-warping strip 1212 is disposed at an end of the pressing cover 121 away from the end hinged to the frame 12.

The implementation principle of the embodiment is as follows: when the canvas 2 needs to be installed, the pressing cover 121 is turned off, the edge of the canvas 2 is prevented between the first clamping plate 131 and the second clamping plate 132, the threaded rod 133 is screwed in a rotating mode, relative rotation occurs between the first clamping plate 131 and the threaded rod 133, and the first clamping plate 131 moves along the length direction of the threaded rod 133 through the adaptive relation between the guide groove 1311 and the guide strip 135 until the rubber layer 136 on the first clamping plate 131 is tightly abutted to the canvas 2, the four edges of the canvas 2 are all fixed by adopting the appellation operation, so that the clamping of the canvas 2 is realized, and the anti-slip fabric 1361 is arranged on the rubber layer 136, so that the effect of stably fixing the canvas 2 is achieved.

After the canvas 2 is installed, the pressing cover 121 is released, the pressing cover 121 automatically rotates under the action of the coil spring to shield the inner wall, and one end of the pressing cover 121 far away from the coil spring is abutted to the frame material 12; when the surface of the canvas 2 receives a slight external force, for example, when the surface of the canvas 2 is blown by wind, the clamping of the first clamping plate 131 and the second clamping plate 132 to the canvas 2 is easily affected, and the friction between the pressing cover 121 and the canvas 2 can be improved to a certain extent by arranging the abutting piece at the position where the pressing cover 121 abuts against the frame material 12, so that the change of the external force to the position of the canvas 2 is reduced to a certain extent; canvas 2 is when fixed, and the border of canvas 2 is not on same horizontal plane with the central authorities of canvas 2, does not influence the display effect of image on canvas 2 when reaching fixed canvas 2, sets up the anti-warp board on gland 121.

When canvas 2 is dismantled to needs change or other reasons, with gland 121 turning away, then twist threaded rod 133 for second clamping plate 132 is kept away from to first clamping plate 131, thereby can dismantle canvas 2, has easy to assemble and dismantles canvas 2 ground effect.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
