Answer: B, C, D.
Answer analysis: When we explore the characteristics of rental products, we are mainly concerned with how these products are convenient to rent, transport, install, and maintain. Now, let's analyze each option one by one to determine whether they reflect the typical characteristics of rental products.
A. Die-cast box design: Die-cast box design is usually related to the sturdiness, sealing, or appearance of the product, but it does not directly reflect the convenience or flexibility of the rental product. The die-cast box may enhance the durability of the product, but it is not a unique feature of rental products. Therefore, although option A may be a product design advantage, it is not a core feature of the rental product.
B. The box can be installed with a quick lock: This feature is directly related to the convenience and efficiency of the rental product. The quick lock installation means that the box (which may refer to the container or packaging for loading the rental equipment) can be quickly and easily installed and removed, which is particularly important for scenarios where the rental equipment needs to be frequently moved and reinstalled. This meets the needs of rental products that need to be quickly deployed and recovered.
C. Power and signal connections use quick plugs: The design of the quick plug is also to improve the efficiency and convenience of equipment connection. In rental scenarios, equipment may need to quickly connect and disconnect power and signal cables in different locations and environments. The design of the quick-connect plug greatly simplifies this process and improves work efficiency, which is an important feature of rental products.
D. Can be installed in a hanging or seated manner: This feature reflects the installation flexibility of the product. Rental products often need to be installed and used in different environments, so providing multiple installation methods (such as hanging or seated) can meet the needs of different scenarios, which is also a reflection of the flexibility and convenience of rental products.
In summary, options B, C, and D all reflect the core characteristics of rental products, namely convenience, flexibility, and efficiency. Although option A may be an advantage in product design, it does not directly reflect the characteristics of rental products.
Therefore, options B, C, and D belong to the characteristics of rental products.
