[0028] Referring now to specific embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Although the present invention will be described in conjunction with specific embodiments, it will be understood that it is not intended to limit the present invention to the described embodiments. Rather, it is intended to cover variations, modifications, and equivalents included within the spirit and scope of the present invention as defined by the appended claims. It should be noted that the method steps described herein can be implemented by any functional block or functional arrangement, and any functional block or functional arrangement can be implemented as a physical entity or a logical entity, or a combination of both.
[0029] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] Note: The examples described below are merely specific examples and are not intended to limit the embodiments of this utility model to the specific steps, values, conditions, data, order, etc. Those skilled in the art can utilize the concept of this utility model to construct more embodiments not mentioned herein by reading this specification.
[0031] Most of the mechanisms / structures used in the industry to open the door are pull-up and pull-down opening methods, which are relatively simple and require a lot of space in front of and above the instrument. They can even affect the operator's operating experience during instrument use and make it inconvenient to use. Therefore, a rotating push-pull mechanism is needed to solve the above problems.
[0032] To solve the problems existing in the installation of the aforementioned warehouse door, this utility model proposes a rotary push-pull mechanism.
[0033] Please see Figure 1 and Figure 2 The rotary push-pull mechanism includes a push-pull assembly, a rotary assembly mounted on the push-pull assembly, and a door 1 connected to the rotary assembly. The rotary assembly includes two rotating shafts 3 disposed on one side of the door 1. The two rotating shafts 3 are fixedly disposed on the door 1 with a left-right distance. The side of the two rotating shafts that are far apart from each other is rotatably connected to the push-pull assembly.
[0034] like Figure 1 and Figure 2 As shown, the overall structure mainly consists of a push-pull assembly, a rotating assembly, and a door 1. The door 1 and the push-pull assembly are connected by the rotating assembly. The push-pull assembly and the rotating assembly are both arranged on the left and right sides of the door 1, and are symmetrically arranged. When the door 1 and the push-pull assembly are in an L-shaped structure, they are perpendicular to each other, so that the height space required for the door 1 does not need to be too high or large, which is convenient for use. When the door 1 and the push-pull assembly are in a straight line, the door 1 can slide upward with the push-pull assembly, realizing the function of rotating the door 1 upward and pushing it into the instrument, which is convenient for spatial use.
[0035] Specifically, the rotating component adopts a rotating shaft 3, which includes a housing and an internal rotating shaft. The housing is connected to the door 1, and the rotating shaft is connected to the push-pull component.
[0036] Please see Figure 1 , Figure 3 and Figure 4 The pivot component 3 is configured as a damping pivot.
[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the damping shaft itself has damping, which can prevent the compartment door 1 from rotating automatically.
[0038] Please see Figures 1-4The push-pull assembly includes two linear guide rails 5 and a connecting block 4 connected to the linear guide rails 5. The connecting block 4 is rotatably mounted on one side of the rotating shaft 3. The distance between the two linear guide rails 5 is set to form a channel, and the door 1 moves within the channel.
[0039] like Figures 1-4 As shown, the two linear guide rails 5 are spaced apart to form a channel, and the door 1 slides between the two linear rails. The door 1 is rotated on the two linear rails through the rotating shaft 3, so that the door 1 can be in two states (vertical state and linear state), realizing the function of rotating the door 1 upward and pushing it into the instrument.
[0040] Please see Figure 1 and Figure 2 A slider 6 is provided at the connection point between the connecting block 4 and the linear guide rail 5. The slider 6 slides inside the linear guide rail 5, and one side of the slider 6 is connected to the connecting block 4.
[0041] like Figure 1 and Figure 2 As shown, the slider 6 has a T-shaped structure, and the groove inside the linear track is adapted to the slider 6, so that the connecting block 4 can slide inside the linear track through the slider 6.
[0042] Please continue reading. Figure 1 and Figure 2 A plug block 7 is fixedly installed at one end of the groove of the linear guide rail 5, and two limit blocks 2 are fixedly installed on one side of the door 1 at the position corresponding to the linear guide rail 5.
[0043] like Figure 1 and Figure 2 As shown, the plug 7 installed at one end of the linear track can block the slider 6 when it slides to this position, and when the door 1 moves, the limit block 2 hits the linear guide rail 5 after it moves to the limit position to prevent the door 1 from detaching.
[0044] Please continue reading. Figure 1 and Figure 2 Multiple threaded holes are provided on one side of the linear guide 5.
[0045] like Figure 1 and Figure 2 As shown, this makes it easy to install the linear track on other devices.
[0046] Please see Figures 1-4 Two limit blocks 2 and two rotating shafts 3 are set at the four corners on one side of the door 1.
[0047] When using this utility model, if the compartment door 1 is perpendicular to the push-pull assembly, the compartment door 1 does not require a large height or much space. When the compartment door 1 and the push-pull assembly are in a straight line, the compartment door 1 can rotate upward and be pushed into the instrument, which is convenient for use in space.
