DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be apparently and completely described below in conjunction with the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are involved in the protection scope of the utility model.

[0021] Although the baffle has been moved away and opened a certain gap in the prior art, since they move away in opposite directions during the moving away process, the space inside the box is not completely exposed after the baffle is moved away, the opened gap still exists shielding, and all the components inside the box cannot be completely exposed, so that the maintenance personnel can only insert the arm through the gap to carry out maintenance, and at this time, due to the limitation of the gap, the vision of the maintenance personnel is shielded, and all the components needing maintenance, especially some details and difficult-to-contact parts inside the box, cannot be completely viewed and evaluated. Please refer to Figures 1-4 The utility model provides a kind of air-cooled box type condensing unit, including base plate 1, two baffles 2 are symmetrically hinged in front and back of base plate 1, two closing plates 3 are symmetrically hinged in the left and right sides of base plate 1, two closing plates 3 are adapted to two baffles 2, cross plate 4 is fixed on the top of base plate 1, and machine mounting plate 5 is fixed on the top of cross plate 4. Condensing unit is installed on the top of machine mounting plate 5, and air-cooled unit is installed on two baffles 2 and two closing plates 3, or two of them.

[0022] As Figures 2-4As shown, due to the limitation of the gap, the operator's view is blocked when operating, and he cannot clearly see all the components that need to be repaired, especially some details inside the box and parts that are difficult to access. It is still not possible to completely view and evaluate. In order to fully display the unit and provide the best repair angle for the repair personnel, the following settings are made. The operating cavity is formed between the operating plate 5 and the base plate 1, and the inside of the operating cavity is provided with an opening and closing mechanism 6. The opening and closing mechanism 6 includes two sliding plates 61 symmetrically arranged inside the operating cavity. The back side of the two sliding plates 61 is symmetrically hinged with two stop plates one 62. The two ends of the two sliding plates 61 are symmetrically hinged with two movable plates 63. The end of the two movable plates 63 away from the sliding plate 61 is hinged with two stop plates two 64. The inside of the operating cavity is provided with a limiting assembly for enabling the two stop plates two 64 to slide along the inner wall thereof. The limiting assembly includes a sliding block 65 fixed to the bottom of the stop plate two 64. The inner wall of the operating cavity is provided with a sliding groove. The inner cross section of the sliding groove is larger than the outer cross section of the sliding block 65. The sliding groove and the sliding block 65 constitute a sliding structure. The inside of the transverse plate 4 is provided with a power assembly 67 for enabling the two stop plates one 62 and the two stop plates two 64 to displace towards different directions and respectively abut against two baffle plates 2 and two sealing plates 3 to open. The power assembly 67 includes a rectangular slot opened in the inner wall of the transverse plate 4 and penetrating through the front and back thereof. The inner wall of the rectangular slot is fixed with a motor 671. The output end of the motor 671 is fixed with a bidirectional threaded screw rod 672. The two sliding plates 61 are threadedly connected to the outer wall of the bidirectional threaded screw rod 672 and slide left and right along the length direction of the rectangular slot. The four corners of the base plate 1 are provided with a reset assembly 68 for enabling the two stop plates one 62 and the two stop plates two 64 to close when they are away from the two baffle plates 2 and the two sealing plates 3. The reset assembly 68 includes four recesses opened in the four peripheral edges of the base plate 1. The inside of the four recesses is rotatably connected with four turnover shafts 681.

The outer wall of the two ends of the four turnover shafts 681 is symmetrically sleeved with two torsional springs 682. The two ends of the two torsional springs 682 are respectively fixed with the turnover shaft 681 and the recess. When the unit needs to be repaired, first, the starting of the motor 671 can produce a forward and reverse rotation. This rotating action is transmitted to the two sliding plates 61 through the bidirectional threaded screw rod 672 and drives them to slide away from each other, producing a certain displacement. In the sliding process, the sliding plate 61 will push the two stop plates one 62 to contact the two baffle plates 2. At the same time, the away sliding of the two sliding plates 61 directly pushes the two movable plates 63. The movement of the movable plate 63 causes the two stop plates two 64 to move, and the two stop plates one 62 and the two stop plates two 64 form a crosswise opposite movement, abut and twist the two hinged baffle plates 2 and the two sealing plates 3, and twist the torsional spring 682 to open. When the unit is completely opened, the operator can clearly view the inside of the unit, ensuring that the repair and maintenance work can be carried out from the best angle.After the maintenance, the relative movement of the two stop plates 62 and the two stop plates 64 forms a cross, at this time, the two stop plates 2 and the two stop plates 3 are automatically reset and closed by the torsion force of the torsion spring 682.

[0023] As shown in Figures 2-3 The end of each stop plate 62 adjacent to the stop plate 2 is equipped with a ball 66 to reduce friction, the end of each stop plate 64 adjacent to the stop plate 2 is also equipped with a ball 66 to reduce friction, the ball 66 is used to reduce the friction when sliding, so as to improve the stability of the movement and reduce the abrasion, prolong the service life. The opposite side of the stop plate 2 and the opposite side of the stop plate 3 are coated with a wear-resistant layer, the wear-resistant layer is formed by at least three times of coating with polytetrafluoroethylene. The opposite side of the stop plate 2 and the opposite side of the stop plate 3, especially the contact surface with the ball 66, are coated with a wear-resistant layer, the wear-resistant layer is made of polytetrafluoroethylene material and is formed by at least three times of coating, the material has excellent wear resistance and low friction coefficient, so as to effectively reduce the abrasion during long-time operation.

[0024] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the protection scope of the present application.
