An outer cavity 5 is formed between the outer box body 1 and the inner box body 2. An outer through hole 6 and an inner through hole 7 are respectively opened on the side walls of the outer box body 1 and the inner box body 2. The installation inner cavity 4, the inner through hole 7, the outer cavity 5, and the outer through hole 6 are connected in sequence from the inside to the outside. The square ram of the present utility model has a double-layer box structure inside and outside. While the square ram increases rigidity through the support frame 3, it reduces the overall weight, which is beneficial for movement and also conforms to the principle of lightweight. Compared with the square ram with a single-layer box structure that increases rigidity by increasing the wall thickness of the casting in the prior art, under the condition of basically the same weight, the structural rigidity of the square ram with a double-layer box structure of the present utility model is increased by 30%. And the square ram has two cavities, namely the installation inner cavity 4 and the outer cavity 5 inside. The installation inner cavity 4, the inner through hole 7, the outer cavity 5, and the outer through hole 6 are connected in sequence from the inside to the outside. When the internal heat-generating components generate heat, the air flow rises, the relative temperature of the outer cavity 5 is lower, the air flow descends, and the installation inner cavity 4 and the outer cavity 5 are connected, so that convection can be formed, which is beneficial for heat exchange and improves the heat dissipation effect of the square ram.

[0028] In this embodiment, both the outer box body 1 and the inner box body 2 are rectangular parallelepipeds, and the cross-section of the support frame 3 is in the shape of a well, so that the support frame 3 divides the outer cavity 5 into an upper outer cavity 51, a lower outer cavity 52, a left outer cavity 53, a right outer cavity 54, an upper left outer cavity 55, a lower left outer cavity 56, an upper right outer cavity 57, and a lower right outer cavity 58 with the inner box body 2 as the central reference orientation. This structure further improves the rigidity and strength of the overall structure of the square ram and ensures structural stability.

[0029] In this embodiment, the upper left outer cavity 551, the upper outer cavity 51, the upper right outer cavity 57, the right outer cavity 54, the lower right outer cavity 58, the lower outer cavity 52, the lower left outer cavity 56, and the left outer cavity 53 are connected in sequence from beginning to end in the clockwise direction, so that the heat generated by the components installed through the installation inner cavity 4 can be dissipated in all directions towards the periphery, further improving the ventilation and heat dissipation effects.

[0030] In this embodiment, a plurality of connecting plates 8 are provided between the outer box body 1 and the inner box body 2. The outer cavity 5 is divided into a plurality of independent cavities in the length direction by the connecting plates 8. Connecting holes 9 are opened on the connecting plates 8, and the plurality of independent cavities are connected to each other through the connecting holes 9, further improving the connection stability between the outer box body 1 and the inner box body 2 and ensuring the heat dissipation effect at the same time.

[0031] In this embodiment, each connecting plate 8 is provided with four communication holes 9, and the positions of the four communication holes 9 correspond to the upper outer cavity 51, the lower outer cavity 52, the left outer cavity 53, and the right outer cavity 54 respectively, so that the size of the communication holes 9 is larger to ensure the ventilation and heat dissipation effect.

[0032] In this embodiment, the communication holes 9 are in a runway shape, making full use of the area of the connecting plate 8 while ensuring the heat dissipation effect.

[0033] In this embodiment, there are three groups of outer through holes 6, and the three groups of outer through holes 6 are respectively arranged on the side walls of the outer box body 1 corresponding to the upper outer cavity 51, the left outer cavity 53, and the right outer cavity 54.

[0034] In this embodiment, the outer through holes 6 are circular. A rectangular groove 10 is formed outside the side wall of the outer box body 1 corresponding to the periphery of the outer through holes 6. Reinforcing ribs 11 are connected between the four corners of the rectangular groove 10 and the outer wall of the outer through holes 6 to improve the strength and stability.
