DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0027] like Figures 1 to 5As shown, a cathode ray tube comprises a ray tube 1, a connecting rod 2 fixedly connected to the bottom end of the ray tube 1, a disassembly mechanism 32 is arranged below the ray tube 1, a support and storage mechanism 31 is arranged below the disassembly mechanism 32, the support and storage mechanism 31 comprises a support column 311 arranged at the bottom end of the connecting rod 2, a support chassis 312 is fixedly connected to the bottom end of the support column 311, a fixing block 313 is fixedly connected to the top end of the supporting chassis 312, a first sliding hole is opened on the outer wall of the fixing block 313, a first spring 314 is fixedly connected to the inner wall of the first sliding hole, a sliding rod 315 is fixedly connected to the end of the first spring 314 away from the inner wall of the first sliding hole, and the outer wall of the sliding rod 315 is slidably connected to the inner wall of the first sliding hole. On the inner wall of the first sliding hole, a connecting plate 316 is fixedly connected to the bottom end of the outer wall of the sliding rod 315, a second sliding hole is opened on the outer wall of the support chassis 312, and a supporting sliding rod 317 is slidably connected to the inner wall of the second sliding hole, and the connecting plate 316 is fixedly connected to the top outer wall of the supporting sliding rod 317 at one end away from the sliding rod 315, and an auxiliary supporting plate 318 is fixedly connected to the outer wall of one end of the supporting sliding rod 317, and a rubber protrusion 319 is fixedly connected to the bottom end of the auxiliary supporting plate 318, and a clamping plate 3110 is fixedly connected to the end of the supporting sliding rod 317 away from the auxiliary supporting plate 318, a clamping hole 3111 is opened on the top of the clamping plate 3110, and a clamping protrusion 3112 is fixedly connected to the bottom end of the support column 311.

[0028] Furthermore, the bottom end of the inner wall of the first sliding hole opened on the outer wall of the fixing block 313 is connected to the top end of the inner wall of the second sliding hole opened on the outer wall of the supporting chassis 312, so that the connecting plate 316 can move therein, thereby facilitating the connection and movement between the sliding rod 315 and the supporting sliding rod 317.

[0029] Furthermore, there are four auxiliary support plates 318 , which are evenly and equidistantly distributed on the outer wall of the support chassis 312 , so that the diameter range around the support chassis 312 can be increased, thereby improving the support stability of the support chassis 312 .

[0030] Furthermore, the material of the card protrusion 3112 is rubber material, and the outer wall of the card protrusion 3112 is larger than the inner wall of the card hole 3111. By setting it to rubber material, when the auxiliary support plate 318 is pulled, the card protrusion 3112 can be squeezed, thereby generating a deformation effect, thereby facilitating the card connection operation with the card plate 3110.

[0031] The disassembly and assembly mechanism 32 includes a block 321 fixedly connected to the bottom end of the connecting rod 2, a support block 322 fixedly connected to the outer wall of the support column 311, a third sliding hole is opened on the outer wall of the support block 322, a second spring 323 is fixedly connected to the inner wall of the third sliding hole, the second spring 323 is fixedly connected to a block 324 at one end away from the inner wall of the third sliding hole, a pull rod 325 is fixedly connected to the outer wall of one end of the block 324, and the outer wall of the pull rod 325 movably penetrates the inner wall of the third sliding hole.

[0032] Furthermore, a clamping hole is provided on the outer wall of the clamping block 321, and the inner wall of the clamping hole fits closely with the outer wall of the clamping column 324. A clamping groove is provided on the top of the support column 311, and the inner wall of the clamping groove fits closely with the outer wall of the clamping block 321, thereby ensuring the stability of the clamping between the ray tube 1 and the support column 311.

[0033] Furthermore, a slope is provided at the top of one end of the clamping column 324 away from the pull rod 325 . Through the slope, when the clamping block 321 moves downward, the clamping column 324 can be squeezed, thereby facilitating the clamping installation of the ray tube 1 .

[0034] The implementation principle of a cathode ray tube of this embodiment is as follows: the support chassis 312 can be used to initially support the ray tube 1. When the support range of the support chassis 312 needs to be increased, the auxiliary support plate 318 can be pulled outward. When the auxiliary support plate 318 moves outward, the support slide bar 317 can be driven to move outward. When the support slide bar 317 moves outward, the clamping plate 3110 can be driven to move outward, thereby driving the clamping hole 3111 opened at the top thereof to move outward. At this time, the inner wall of the clamping hole 3111 will squeeze the clamping protrusion 3112, and the squeezed clamping protrusion 3112 will be deformed until it is completely detached. The clamping plate 3110 will then lose its limiting effect and the first spring 314 will rebound to push the slide bar 315 and the connecting plate 316 outward. When the connecting plate 316 moves, it can drive the supporting slide bar 317 and the auxiliary supporting plate 318 to move outward. In this way, the auxiliary supporting plates 318 at all places can be expanded, thereby increasing the supporting diameter range of the supporting chassis 312, thereby improving the supporting stability of the supporting chassis 312. At the same time, the support of the rubber protrusion 319 can increase the friction between the supporting chassis 312 and the supporting surface, thereby further improving the supporting stability of the supporting chassis 312.

[0035] When it is necessary to install the ray tube 1, it is only necessary to insert the clamping block 321 at the bottom into the clamping groove at the top of the supporting column 311. During the insertion of the clamping block 321, the clamping column 324 can be squeezed, and the squeezed clamping column 324 will move to the left and right directions, and at the same time, the second spring 323 will be squeezed until the clamping hole opened on the outer wall of the clamping block 321 moves to the position of the clamping column 324. Then, the second spring 323 rebounds and pushes the clamping column 324 to be clamped on the inner wall of the clamping hole, thereby completing the positioning of the clamping block 321 and completing the installation with the ray tube 1. When disassembling, it is only necessary to pull the pull rod 325 to drive the clamping column 324 to separate from the inner wall of the clamping hole to complete the disassembly. In this way, when the ray tube 1 is not in use, it can be disassembled from the supporting chassis 312 at the bottom, thereby reducing the placement space and facilitating storage.
