Description

Technical Field

[0002] The main purpose of the photovoltaic landscape transformer with an assembled shell is to solve the difficulties encountered in the installation, maintenance and transportation of traditional transformers. This device significantly improves the efficiency and maintenance convenience of the transformer by adopting components that are easy to disassemble and reassemble.

[0003] The existing Chinese patent (publication number CN214476775U) discloses a photovoltaic landscape transformer with an assembled shell. By setting a dovetail bar, a fixed rod, a movable rod and an adjustment rod, under the action of the dovetail bar, it is convenient to fix and install the bottom plate, the side plate and the front plate. When the rear plate is inserted from top to bottom into the outside of the fixed bar, the adjustment rod can be driven to rotate under the extrusion effect, so that the movable rod slides and is engaged and connected with the first installation rod and the second installation rod, thereby facilitating the stable splicing of the various parts of the shell and facilitating disassembly and assembly.

Although this fixing method ensures the stability of the structure to a certain extent, too many welding points may cause stress concentration under the influence of external forces or environmental factors for a long time, thereby causing fatigue damage to the welding parts. Especially when the external force acts unevenly, the stability will be greatly reduced. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] This embodiment provides a technical solution, such as Figures 1 to 4 As shown, a photovoltaic landscape transformer with an assembled housing includes a mounting shell 1 and a fan 11 mounted on the mounting shell 1, and a buckle assembly 2 is provided on the mounting shell 1;

[0030] The buckle assembly 2 includes a mounting plate 214; the mounting plate 214 is fixedly connected to the inside of the mounting shell 1, a mounting frame is fixedly connected to the mounting plate 214, a fourth rotating shaft 29 is rotatably connected to the mounting frame on the mounting plate 214, a triangular member 28 is rotatably connected to the fourth rotating shaft 29, a third rotating shaft 27 is rotatably connected to the triangular member 28, a second connecting rod 26 is rotatably connected to the third rotating shaft 27, a first rotating shaft 22 is rotatably connected to the side of the second connecting rod 26 away from the third rotating shaft 27, a buckle 21 is rotatably connected to the first rotating shaft 22, and a clamping column 25 is fixedly connected to the buckle 21;

[0031] When a new mounting shell 1 needs to be installed, the air pump 211 is started, and the air pump 211 then inflates the air cylinder 210 through the ventilation pipe 212, increasing the air pressure therein, so that the rubber piston rod 213 is pushed out under the action of the air pressure, driving the triangular piece 28 to rotate, so that the second connecting rod 26 drives the snap member 21 to rotate on the second rotating shaft 23, so that the snap member 21 drives the clamping column 25 to be clamped into the mounting shell 1 and the clamping groove on the connecting plate 215, thereby realizing the installation of the new mounting shell 1. In addition, by applying a pneumatic drive method, it has a certain shock-absorbing effect, and the device is more stable, which solves the problem that the prior art in the background technology does not have a shock-absorbing structure, and too many welding points may cause stress concentration under the influence of external forces or environmental factors for a long time, thereby causing fatigue damage to the welding parts.

[0032] Further, such as Figure 1 As shown, three third rotating shafts 27 are provided, and the three third rotating shafts 27 are all rotatably connected to the triangular member 28. The third rotating shaft 27 on the side away from the clamping column 25 among the three third rotating shafts 27 is rotatably connected to the rubber piston rod 213. By providing a rubber piston and a gas cylinder 210, when the gas cylinder 210 is inflated, the rubber piston is driven to be pushed out, so that the triangular member 28 rotates, and the buckle 21 can be driven to rotate on the second rotating shaft 23, and the clamping column 25 is driven to be clamped into the clamping groove on the connecting plate 215 and the mounting shell 1;

[0033] The rubber piston rod 213 is slidably connected with the air cylinder 210. By providing the air cylinder 210 and the rubber piston, the rubber piston rod 213 drives the triangular piece 28 to rotate, thereby realizing the transmission of the buckle 21. The rubber piston rod 213 is pneumatically driven, has a certain shock-absorbing effect, and occupies little space.

[0034] The air cylinder 210 is fixedly connected to the mounting shell 1, and is fixedly connected to a ventilation pipe 212.

Figures 1 to 4 As shown, the second rotating shaft 23 is rotatably connected to the buckle 21, and the first connecting rod 24 is rotatably connected to the second rotating shaft 23. A connecting plate 215 is fixedly connected to the first connecting rod 24 on one side away from the second rotating shaft 23. By providing the connecting plate 215, it is convenient to connect the buckles 21 on both sides and the second rotating shaft 23, so that the buckle 21 can rotate, driving the clamping column 25 to clamp in and out of the connecting plate 215 and the clamping groove on the mounting shell 1;

[0036] The mounting shell 1 and the connecting plate 215 are provided with a clamping groove, and the clamping column 25 is clamped in the clamping grooves on the mounting shell 1 and the connecting plate 215. By providing the clamping groove, the clamping column 25 is conveniently clamped to achieve the connection to the housing.

[0037] Working principle:

[0038] like Figure 1-4 As shown: when a new mounting shell 1 needs to be installed, the air pump 211 is started, and the air pump 211 then inflates the air cylinder 210 through the ventilation pipe 212, increasing the air pressure therein, so that the rubber piston rod 213 is pushed out under the action of the air pressure, driving the triangular piece 28 to rotate, so that the second connecting rod 26 drives the snap member 21 to rotate on the second rotating shaft 23, so that the snap member 21 drives the clamping column 25 to be clamped into the mounting shell 1 and the clamping groove on the connecting plate 215, thereby realizing the installation of the new mounting shell 1. In addition, by applying a pneumatic drive method, it has a certain shock-absorbing effect, and the device is more stable, which solves the problem that the prior art in the background technology does not have a shock-absorbing structure, and too many welding points may cause stress concentration under the influence of external forces or environmental factors for a long time, thereby causing fatigue damage to the welding parts.
