Description

TECHNICAL FIELD The present disclosure relates to the technical field of large-screen display and in particular to a modular display screen chassis as well as a display screen. BACKGROUND TECHNOLOGY With the increasing demand for information display, commercial large screens are getting closer to people's daily life, such as displaying advertisement in shopping malls, displaying train and flight information at stations and airports. Meanwhile, with the continuous development of society, people have more and more requirements for the functions of the commercial large screens, such as the requirements for smaller screen spacing, lighter chassis, and easier installation. Indoor display screens, as an important branch of large-screen displays, have developed rapidly in response to the market demand for indoor small-pitch display products, such as cinema screens and storefront screens. Currently, the size and installation method of traditional indoor display screen chassis are rather limited. Customers need a display screen chassis that is compatible with multiple sizes of display screens and can be spliced to form various shapes. SUMMARY OF THE INVENTION A modular display screen chassis includes multiple shells and one or more display modules detachably mounted on the shells. The shells have various preset sizes and each one is provided with a chamfer on its sides for splicing with a chamfer of an adjacent shell at a specific angle. Each of the one or more display modules has a fixed size. Each of the preset sizes is integer multiples of the fixed size. Each of the shells having the plurality of preset sizes corresponds to different numbers of the display modules As a more preferred way, the display modules and the multiple shells are connected by magnetic attraction, and magnetic components are set at corresponding positions of the multiple shells and the display modules. As a more preferred way, the display modules and the multiple shells are connected by a claw structure. The claw structure includes a clamp set on the multiple shells and a corresponding fixed post set on the display modules for connecting with the clamp. As a more preferred way, the clamp includes a base plate, multiple elastic pieces and multiple clamping pieces which are integrally formed with the base plate. A gap between the multiple elastic pieces is configured to accommodate the fixed post, and the multiple elastic pieces are configured to clamp the fixed post. The multiple clamping pieces are configured to fix the clamp with a connecting hole. The multiple elastic pieces configured to clamp the fixed post are used for assembly and disassembly of a panel structure. A center of the base plate is provided with a locating hole. As a more preferred way, the fixed post includes a locating part, a protruding part, and a connecting part, which are integrally molded. The fixed post is connected to the support base through the connecting part. The locating part includes a locating slot adapted to the locating hole. When the fixed post is clamped within the structure of the clamp, the locating part is inserted into the locating hole and a wall of the locating hole restricts a movement of the locating part within the locating slot. The protruding part is in tight contact with the base plate while the multiple elastic pieces restrict a location of the protruding part. As a more preferred way, an angle of the chamfer of the multiple shells is 45°, so that when two shells are fitted together along edges of their chamfers, two adjacent display modules corresponding to the two shells are perpendicular to each other. As a more preferred way, the shells have four sizes, which are respectively 1000 mm×250 mm, 750 mm×250 mm, 500 mm×250 mm and 250 mm×250 mm. The above four sizes of the shells can meet various usage scenarios. As a more preferred way, each of the display modules has a fixed size of 250 mm×250 mm. As a more preferred way, each of the display modules includes a support frame, a circuit board set on the support frame, and a light-emitting unit set on the circuit board. The support frame is detachably connected to the shells, and is used to protect the internal circuit structure of the display modules. In order to solve the above problems, the present disclosure also provides a display screen, including multiple above modular display screen chassis, and the display screen is assembled by splicing adjacent modular display screen chassis two by two. As mentioned above, the modular display screen chassis and display screen of the present disclosure have the following beneficial effects: when the modular display screen chassis of this present disclosure is in use, firstly, the shells of various sizes allow users to choose the appropriate size according to the installation space, improving the applicability of the product and enriching the usage scenarios. Secondly, the sides of the shell are provided with chamfers for assembling with each other at
