Detailed Description
The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 5, the utility model provides a curved back of the chair closing device, it is including the base plate 1 that is the L type, the upside of 1 left end of base plate is provided with hang plate 2 from the upper right side down dip ground, the right-hand member of hang plate 2 is provided with the cylinder 3 with the perpendicular setting of hang plate 2, press back of the chair rod with the back of the chair strip through the cylinder, thereby it is compact and the gap is little to press, the upper end of base plate 1 is provided with type piece 5, be located the baffle 8 on type piece 5 right side, the upper end of type piece 5 vertically is provided with two backing plates 6 that are used for placing the back of the chair, two backing plates can support the back of the chair and make things convenient for the cylinder to press in the left orientation of the crooked back of the chair, the left end of baffle 8 is provided with and can support piece 7 on the back of the chair right side, support the piece can support the back of the chair right side, the baffle can bear the effort of supporting the piece transmission and come.
The end part of the piston rod of the cylinder 3 is provided with a rubber sleeve 4 which can be abutted against the left side of the chair back. The chair back damage can be protected through the butt joint of the rubber sleeve and the chair back, so that the product quality is influenced.
The molding block 5 is contacted with the abutting block 7 and the baffle 8. The arrangement can ensure that the molding block also bears the force transmitted by the resisting block, and the resisting block is greatly stressed.
The contour line at the upper end of the profile block 5 is formed by connecting a middle arc line with transverse lines at the left side and the right side. The contour line of the middle is close to the contour line of the chair back, when the chair back is longitudinally placed on the two base plates, the arc contour of the chair back is tangent to the axis of the piston rod of the air cylinder, so that when the air cylinder drives the rubber sleeve to incline and press down, the left side of the chair back is stressed uniformly, and the chair back strip can be better pressed tightly.
The left end face of the supporting block 7 is formed by connecting an inclined plane at the upper side with a vertical plane at the lower side, the vertical plane can facilitate a worker to fix the supporting block on the baffle, and the inclined plane can be attached to a rod at the right side of the chair back. The inclined plane is attached to the right stick of the chair back, and when the rubber sleeve is pressed down, the stress area of the abutting block is large, and the condition of uneven stress cannot occur.
The department of bending of base plate 1 is provided with stiffener 9, and the stiffener can strengthen the structural strength of the department of bending of base plate, prevents that the department of bending from warping crooked, is provided with strengthening rib 10 between base plate 1 and the baffle 8, and the strengthening rib can support the back of the chair and act on the power of supporting piece, baffle.
The base plate, the inclined plate and the baffle plate are made of iron, and the profile block, the backing plate and the abutting block are made of wood.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
