Detailed Description

The present application is described in further detail below with reference to figures 1-8.

The embodiment of the application discloses a picture frame. Referring to fig. 1 and 2, the picture frame comprises a frame 1, a transparent glass 2 adhered to the frame 1, and a rear baffle 3 detachably mounted on one side of the frame 1 far away from the transparent glass 2. The frame 1 comprises an upper beam 11, a lower beam 12 and two parallel arranged support beams 13. The upper beam 11, the lower beam 12 and the two support beams 13 are fixedly bonded to form a rectangular structure.

Referring to fig. 3, a hanging rope 14 is fixed to the top of the upper beam 11. An upper transverse groove 111 is formed in one side wall of the upper cross beam 11 close to the lower cross beam 12 along the length direction of the upper cross beam, and a lower transverse groove 121 is formed in one side wall of the lower cross beam 12 close to the upper cross beam 11 along the length direction of the lower cross beam. A driving roller 4 is rotatably arranged in the upper transverse groove 111 and the lower transverse groove 121, and a conveying belt 5 for pasting paintings 8 is connected and arranged between the two driving rollers 4. A driving assembly 6 for driving the conveyor belt 5 to rotate is arranged in the frame 1. The driving roller 4 is driven to rotate by the driving component 6, so that the paintings 8 stuck on the conveyor belt 5 are replaced.

Referring to fig. 4, the driving assembly 6 includes a worm wheel 61 and a worm 62. The worm wheel 61 and the worm 62 have a self-locking function. The worm wheel 61 is fixedly arranged on the outer wall of one end of the driving roller 4 in the lower transverse groove 121, and the worm 62 is rotatably arranged in the lower transverse groove 121 and meshed with the worm wheel 61. The end of the worm 62 away from the transparent glass 2 passes through the groove wall of the lower transverse groove 121 and extends to the outer surface of the lower beam 12, and the end is flush with the outer surface. Still fixed welding has the rolling disc 621 on the one end outer wall that transparent glass 2 was kept away from to worm 62, offers the counter sink 122 that supplies the rolling disc 621 embedding on the outer wall of bottom end rail 12, and counter sink 122 and the coaxial setting of worm 62, and the degree of depth of counter sink 122 is greater than the thickness of rolling disc 621 for rolling disc 621 can not contact with the wall body, and the hanging of the frame of being convenient for is established. To facilitate the installation of the worm 62, the two long-side groove walls of the lower beam 12 are installed by splicing.

Referring to fig. 5 and 6, an adjusting member 7 for adjusting the tension of the conveyor belt 5 is further installed in the upper cross channel 111. The adjusting member 7 includes an adjusting rod 71 and adjusting nuts 72 threadedly coupled to both ends of the adjusting rod 71. The adjusting rod 71 is arranged in parallel with the driving roller 4 and is located below the driving roller 4. The adjusting rod 71 is also rotatably sleeved with a rolling sleeve 73, and the length of the rolling sleeve 73 is larger than the width of the conveyor belt 5. The two wide side walls of the upper transverse groove 111 are both provided with an adjusting groove 112 for inserting the end of the adjusting rod 71. The length direction of the adjustment groove 112 is the same as the width direction of the upper cross beam 11. When the adjusting rod 71 is positioned at one end of the adjusting groove 112 close to the transparent glass 2, the rolling sleeve 73 is not in contact with the inner side of the conveyor belt 5; when the adjustment lever 71 is located at an end of the adjustment groove 112 remote from the transparent glass 2, the rolling sleeve 73 stretches the conveyor belt 5 to a maximum tension within the adjustment range.

Referring to fig. 7 and 8, a stepped groove 131 for the rear baffle 3 to be embedded is formed in one side of the two support beams 13 away from the transparent glass 2, and the thickness of the rear baffle 3 is smaller than the depth of the stepped groove 131. The border department of backplate 3 installs a plurality of and rotates knot 31, rotates to detain 31 when rotating, and there is frictional force between the backplate 3 for rotate and detain 31 and can not hang down automatically under the action of gravity, and the outside extension of one side cell wall that two ladder grooves 131 kept away from each other has the joint groove 132 that supplies to rotate knot 31 male along frame 1 week side.

The implementation principle of a picture frame in the embodiment of the application is as follows:

when the painting 8 is pasted on the conveying belt 5, the rear baffle 3 is detached, the painting 8 is pasted on the conveying belt 5 in an inverted mode relative to the picture frame, the rotating disc 621 is driven to drive the worm wheel 61 to rotate, and therefore the conveying belt conveys one side, to which the painting 8 is pasted, to one side close to the transparent glass 2; and continuously pasting another painting 8 on the conveyor belt 5, covering the rear baffle 3, and hanging the picture frame on the wall.

When the painting 8 that the change will demonstrate, turn up the bottom of frame a little, the staff drive is located the rolling disc 621 at the frame back for driving roller 4 rotates, and then makes painting 8 convey along conveyer belt 5, and the painting 8 that is located conveyer belt 5 and is close to 3 one sides of backplate can convey to the frame openly, demonstrates, reaches the purpose that conveniently changes the painting 8 that will demonstrate.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
