M322051 VIII. New description: [New technical field] This is a kind of pavilion-type transformer box cover opening and positioning device, especially when the box cover of the pavilion-type transformer is opened upwards, the cover can be securely fixed. For subsequent related work. [Prior Art] According to the '--the pavilion-type transformers are placed in the required space in a considerable volume, and they are installed in the secondary side cover f of the plaque, the tap changer, the double voltage switch and Components such as high-pressure bushings are usually [optional to be covered by a lid that can be opened or closed. However, in the case of the repair of the Wei field wiring, it is necessary to expose the above-mentioned box cover to the main working components as described above. However, in the existing pavilion type pressure swing leg structure, the Wei H button and the lid are basically pivotal joints such as bribes. Therefore, when performing the related operations as described above, the staff usually
The living hinge directly opens the lid of the action shaft, and the main body of the lid and most of the weight f are placed in the face of the Han H rhyme. The cover is opened in a state where the center of gravity is naturally positioned, and it is easy to be violently combined by an external force collision or a strong wind, so that this type of work is easy for the thief to face the surface of the work, and it is necessary to improve. [New content] The main purpose of this creation is to provide a kind of pavilion-type device cover and open positioning device. Inclined cover, 5 M322051 staff caused accidental injury. In order to achieve the goal, the creation-type transformer box body is composed of a front panel, an upper and lower panel and two side panels, and is assembled at the front end of the front panel-box cover, which is common to the front end surface, the two side surfaces and the top surface. Forming the above-mentioned box cover at the intersection of the rear end of the top surface and the upper panel of the box body by a hinge connection; the feature is that at least the corner of the box body and the box cover are respectively provided with a sleeve with a sleeve hole, ^ The above two sleeves are in a split state of the lid to become two different planes at different height positions.
The sleeve of the control box cover; a latch member is inserted into the sleeve hole of the two sleeves to open the positioning. In a preferred embodiment, the latch member is provided with a main body portion that fits the length of the two sleeves in the box cover and extends from the two ends of the main body portion - a long folded edge and a short folded edge. The pavilion is located in the casing hole of the box and the cover. In a possible embodiment, the box body is provided with the sleeve-containing sleeve above the two sides of the front panel at the same time, and the ship is provided with a sleeve with a corresponding sleeve hole in the top_table_difficulty. [Embodiment] ▲, j, and new syllabus and others _ will be clarified by the detailed description of the following examples.
The gantry-type illuminating device shown in Fig. 1 is provided with a box body (i) the phase body (10) is composed of a front panel (11) (see Fig. 3), a rear panel 2), and upper and lower panels (13). , (14) and _ board (15) together form a 6 M322051 transformer housing of the required size. A base (30) of a certain height is disposed at a front end of the front panel (11), and a cover (20) is disposed above the base (30), and the cover (20) is provided by a front end surface (2 1 ) The two sides (2 2 ) and the top surface (23) are combined. In this embodiment, the cover (20) is at the intersection of the rear end of the top surface (23) and the upper panel (13) of the cabinet (1). The entire cover (20) can be closed with the hinge (16) as the axis of motion (as shown in Figure 1) or upward (as shown in Figure 3). Please refer to Figures 2 and 3 for the Lu. The above-mentioned box (1〇) is provided with a secondary side bushing (40), a tap changer (4 1), and a dual voltage switch (4 2) required for such a transformer on the front panel (1 1). And the high-pressure bushing (43), etc. The front cover surface (21) of the cover (20) is provided with a locking piece (24) having a long slot (25) and a rotatable position near the center of the bottom edge. a bolt (2 6); the base (30) is provided with a notch (31) at a position opposite to the locking piece (24) and the bolt (26) for providing a through hole (34) The locking piece (3 • 2) and a screwing part (3 3 ) enable the entire cover (20) to be locked by a lock (3 5) in the state shown in Figures 1 and 2 The hook (36) is locked by the through hole (3 4) to be closed, or can be locked (3 5) After opening, the lid (20) is opened to the open state as shown in Fig. 3. This creation is displayed in the box cover (20) in the open state, and is displayed in at least one corner of the box (10). The opposite corners of the cover (2 〇) are respectively provided with sleeves (17) and (27) including sleeve holes (1 8) and (28), as shown in Figures 4, 5 and 8 In the preferred embodiment, the present invention is provided with a sleeve (1 8 ) with a sleeve hole (1 8 ) on the upper side of the front panel (1 1) of the cabinet (1 1), and a casing cover (2 0 ). The top surface of the top surface (23) is provided with a sleeve (2 7 ) with a sleeve hole (28), so that the two sleeves (17), (27) and the sleeve hole (! 8) (2 8) in the case of the cover (20), the two non-same plane plug-in kits at different height positions; a preset latch (50) is movable to simultaneously insert or disengage the sleeve In the sleeves (18) and (28) of (7), (2), the control box cover (2 〇) is opened or closed. • In the preferred embodiment, the above-mentioned latch member (5) 0) provided with a body portion (5 1) 'to fit the two sleeves (17), (27) in the lid 20) a spacing interval formed when the opening is opened and a long folding edge (52) and a short folding edge (53) are respectively extended from the two ends of the main body portion (5 work), and the entire latch member (50) It can be positioned as the sleeve hole of the phase body (10) and the cover (2 〇) according to the 4th and 5th riding. ), (2 8 ). As shown in Figure 6, the above-mentioned _piece (5 Q) is in the un-state (ie, the lid (2 0 ) is closed), so that its long hem (5 2) is completely inserted into the casing (!7). Set the hole (18), and make its main part (5 i) and short fold (5 3 is in a floating standby state. When the cover (20) is opened and reached (after the point, as shown in Figure 7, The latch member (50) can be pulled up from the sleeve hole (丄8) of the sleeve (17), and the short flange (5 3) can be aligned with the sleeve (2 7) at a rotation angle. After the hole is set (2 8), the complete cover (2 〇) is inserted downward. Conversely, the short fold (5 3) of the latch (5 )) can be removed from the card after the reverse action. (2 0) Closed. 8
M322051 This type of pavilion is equipped with variable pressure n, so that after the lid is opened, it can be quickly and stably positioned safely, and then it can be used for the protection of the workers. It has a secret to the safety of work, and it has the value of industrial use. It proposes a new type of patent application according to law.
