Detailed Description
In order to make the technical problem, technical solution and advantageous effects solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to further explain the present invention in detail. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The utility model provides a self-supporting turns over door mechanism down has following advantage: (1) the downward-turning door can be maintained at a specific angle after being completely opened, so that the operation of operators is facilitated; (2) after the downward-turning door is completely opened, the downward-turning door is supported by the triangular stable supporting mechanism, so that the structural stability is good; (3) the operation personnel can use the utility model conveniently.
Referring to fig. 1 to 4, the self-supporting flip-down door mechanism includes a flip-down door panel 1, a chute 2, and a support bar 3.
The handle 5 is fixedly arranged outside the downward-turning door plate 1, so that the operation and the use of a user are facilitated.
The downward-turning door plate 1 is arranged above the sliding chute 2, and the bottom of the downward-turning door plate 1 is rotatably connected with the top of the sliding chute 2 through a downward-turning door rotating shaft 4; one end of the support rod 3 is rotatably connected with the side surface of the downward turning door plate 1 through a support rod rotating shaft 3-1; the other end of the supporting rod 3 is fixedly provided with a fixed shaft 3-2, a sliding block 3-3 is sleeved outside the fixed shaft 3-2, and the sliding block 3-3 can rotate relative to the fixed shaft 3-2; the sliding block 3-3 adopts a bearing in practical application. The slide 3-3 is embedded in the runner 2.
Thus, as shown in FIG. 2, is a schematic view of the self-supporting tilt-down door mechanism in a fully closed state; when the door needs to be opened, an operator holds the handle 5 to rotate the downward turning door panel 1 around the downward turning door rotating shaft 4 to open the door, and in the door opening process, fig. 3 is a schematic view when the door is opened to 90 degrees; fig. 4 is a schematic view when fully open. In the process of opening the door, one end of the support rod 3 rotates relative to the downward turning door plate 1 through the support rod rotating shaft 3-1, the slide block 3-3 at the other end of the support rod 3 slides downwards along the sliding groove 2, when the slide block 3-3 slides downwards along the sliding groove 2, the support rod 3 gradually inclines along with the rotation of the downward turning door plate 1, therefore, the slide block 3-3 also freely rotates around the fixed shaft 3-2 while sliding downwards, until the slide block 3-3 slides to the bottommost part of the sliding groove 2, the downward turning door plate 1 and the support rod 3 stop rotating due to the limiting effect of the bottommost part of the sliding groove 2, and the downward turning door plate 1, the support rod 3 and the sliding groove 2 form a triangular stable support mechanism. As shown in fig. 4, which is a schematic view when the sliding block 3-3 slides to the bottom of the chute 2. Therefore, when the downward turning door plate is completely opened, the downward turning door plate can be maintained to be unchanged at the angle due to the supporting effect of the triangular stable supporting mechanism, and the stability of the door opening is enhanced.
In the application, since the sliding block 3-3 needs to freely rotate around the fixed shaft 3-2 simultaneously in the process of sliding downwards, and meanwhile, the sliding block 3-3 needs to be ensured not to be separated from the sliding chute, referring to fig. 5-7, the left side and the right side of the sliding chute 2 are provided with a left groove 2-1 and a right groove 2-2 which are symmetrical; the two sides of the sliding block 3-3 are respectively embedded into the left groove 2-1 and the right groove 2-2, so that the sliding block 3-3 slides along the left groove 2-1 and the right groove 2-2, and meanwhile, the sliding block 3-3 is limited by the left groove 2-1 and the right groove 2-2, and the sliding block 3-3 is prevented from being separated from the sliding groove 2.
The utility model provides a self-supporting door mechanism that turns over down, refer to FIG. 1, mainly be applied to the lower part cavity and need not open the door, only need the upper portion cavity occasion of opening the door, in this kind of occasion, the ingenious space that has utilized lower part cavity panel of this application, respectively install the spout in the both sides of lower part cavity panel to the door that turns over down that makes the upper portion cavity when opening the door, makes the bottom of bracing piece slide along the spout simultaneously, strengthens the stability of the process of opening the door.
The utility model provides a self-supporting turns over a mechanism down, this mechanism is simple easily to be realized, fine solution other turn over a poor problem of unstability and convenience of structure down.
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 principle of the present invention, and these improvements and decorations should also be viewed as the protection scope of the present invention.
