[0024] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] Reference Figure 1-5 The utility model embodiment is a push-pull type medical electron linear accelerator housing, which includes: a connecting frame 1, the left and right ends of the connecting frame 1 are fixedly and slidably connected with contoured side panels 2, the lower surface of the connecting frame 1 and the two contoured side panels 2 are in close contact with the surface of the electron linear accelerator, and the above devices form the basic structure of the housing, the lower surface of the contoured side panel 2 is provided with a mounting cavity 5, the interior of the mounting cavity 5 is fixedly connected with a roller 8, and the existence of the roller 8 improves the convenience when the connecting frame 1 and the contoured side panel 2 are docked, and the surface of the contoured side panel 2 is slidably connected with a baffle 6. When the electron linear accelerator is used, the baffle 6 is clamped with the mounting cavity 5, and a side of the baffle 6 close to the roller 8 is fixedly connected with an arc stopper 14, and the arc stopper 14 is in close contact with the roller 8. The baffle 6 cooperates with the arc stopper 14 to improve the stability of the roller 8 in a static state and prevent the housing from accidentally sliding during use.

[0026] Two partitions 11 are arranged inside the connecting frame 1. Both the connecting frame 1 and the partitions 11 are made of lead. A rubber pad 3 is fixedly connected to one side of the partition 11 close to the contoured side panel 2. The upper surface of the rubber pad 3 is in close contact with the contoured side panel 2. The rubber pad 3 reduces the wear effect between the contoured side panel 2 and the partition 11. An adjusting mechanism 9 is arranged on the opposite side of the two partitions 11 and the front and rear surfaces of the connecting frame 1. The adjusting mechanism 9 is composed of a limiting slide groove 13 and a control panel 12. The existence of the adjusting mechanism 9 makes it convenient for the staff to separate the connecting frame 1 from the contoured side panel 2 from the outside, thereby improving the convenience of disassembling the outer shell.

[0027] A group of positioning components 10 are provided on the surface of the two control panels 12, and each group of positioning components 10 has two. The two positioning components 10 are relatively distributed front and back. The positioning components 10 improve the stability of the partition 11 when it acts. The front and rear surfaces of the connecting frame 1 are clamped with a protective cover 4. The front and rear ends of the control panel 12 and the positioning components 10 are all located inside the protective cover 4. The protective cover 4 prevents the positioning components 10 from being affected by external impurities. A rubber filling block 7 is fixedly connected between the control panel 12 and the left and right inner walls of the limiting slide 13. The rubber filling block 7 improves the sealing effect of the limiting slide 13.

[0028] Working principle: When separating the shell from the electron linear accelerator, first separate the protective cover 4 and the positioning assembly 10, and then separate the baffle 6 from the installation cavity 5. At this time, the control board 12 can be used to separate the contoured side plate 2 from the connection frame 1. When using the electron linear accelerator, the presence of the rubber pad 3 reduces the friction damage between the contoured side plate 2 and the partition 11, thereby avoiding serious damage to the shell components due to vibration and collision, and extending the service life of the shell.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
