Obviously, the described embodiments are only part of the preferred embodiments of the utility model, not all of the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0018] The utility model provides a novel box body with a retractable door (such as Figure 1As shown), it includes a box body 1, and a telescopic door 2 is arranged on the upper left side and / or right side of the box body 1. In actual applications, a telescopic door 2 can be arranged on the left side or right side or both sides of the box body 1 according to actual needs. The telescopic door 2 can be freely rotated and telescopically moved left and right relative to the box body 1. The free rotation ability of the telescopic door 2 relative to the box body 1 can be used to open the telescopic door 2, that is, the telescopic door 2 can be changed from a vertical state to a horizontal state. The telescopic door 2 can be pushed into the inside of the box body 1 by the telescopic movement ability of the telescopic door 2 relative to the box body 1, and then the telescopic door 2 can be hidden. After the telescopic door 2 is hidden, the occupied space of the entire box can be reduced, and then it is convenient for the truck to load and unload goods in a smaller space. At the same time, scratches can be avoided. Risk; a slide rail 21 is arranged on the front side edge and the rear side edge of the inner wall of the telescopic door 2, and a slide seat 5 is arranged on the slide rail 21, and the slide seat 5 can slide and position freely relative to the slide rail 21. When the slide seat 5 and the slide rail 21 keep sliding relative to each other, it is convenient to realize the left and right movement of the telescopic door 2. When the slide seat 5 and the slide rail 21 are locked and the slide seat 5 remains stationary, the telescopic door 2 can be locked and fixed in a horizontal state; a gas spring support rod 6 corresponding to the slide seat 5 is hingedly arranged at the lower part of the inner wall of the front box wall 11 and the rear box wall 12 of the box body 1. The gas spring support rod is a prior art product in this technical field, so the detailed structure and working principle of the gas spring support rod are not described in detail here. The fixed end of the gas spring support rod 6 is hingedly connected to the corresponding bottom of the slide seat 5. Specifically, the telescopic end of the gas spring support rod 6 is hingedly connected to the inner side of the corresponding front box wall 11 or rear box wall 12. When installing and positioning the hinge support point of the telescopic end of the gas spring support rod 6, it is necessary to first open the telescopic box door 2 and put it in a horizontal position. Then, the fixed end of the gas spring support rod 6 in the extended state is hingedly connected to the lower part of the slide seat 5. After completion, the telescopic end of the lower part of the gas spring support rod 6 is hingedly connected to the inner side of the front box wall 11 or the rear box wall 12. The elastic function of the gas spring support rod 6 is utilized, so that the labor intensity of opening the telescopic box door 2 can be greatly reduced when it is manually opened.

[0019] On the basis of the above embodiments, the specific implementation method of the telescopic door 2 being able to freely rotate and slide left and right relative to the box body 1 is as follows: a C-shaped slide 13 is arranged on the upper inner wall of the front box wall 11 and the rear box wall 12, and the two C-shaped slides 13 are symmetrically distributed front to back, and a first bearing 21 is fixedly installed on the upper front and rear sides of the telescopic door 2. Specifically, a support shaft is fixedly arranged on the upper front and rear side walls of the telescopic door 2, and the inner ring of the first bearing 21 is fixedly arranged on the support shaft, and the first bearing 21 is clamped in the corresponding C-shaped slide 13. The support shaft is used to realize the free rotation of the outer ring of the first bearing 21 to realize the free rotation of the telescopic door 2 relative to the box body 1, and the free sliding of the first bearing 21 in the C-shaped slide 13 to realize the free sliding of the telescopic door 2 relative to the box body 1.

[0020] On the basis of the above embodiment, in order to improve the convenience of left and right movement of the telescopic box door 2, a support seat is fixedly arranged below the left and right ends of the C-shaped slide 13, and the support seat includes a locking nut 41 and a fixing plate 42. The locking nut 41 is fixedly connected to the fixing plate 42, and a through hole that penetrates the locking nut 41 is arranged on the fixing plate 42. When the support seat is installed, the fixing plate 42 is fixed to the corresponding front box wall 11 and rear box wall 12, and a locking bolt 43 is sleeved on the locking nut 41. A second bearing 44 and a supporting sleeve 45 are sleeved on the locking bolt 43, and the supporting sleeve 45 is adjacent to the fixing plate 41. When the locking bolt 43 is screwed into the locking nut 41, the locking bolt 43 can be continuously rotated to lock the locking nut 41. The nut of the tightening bolt 43 presses the second bearing 44 and the support sleeve 45 tightly against the support plate 42, thereby realizing the positioning of the second bearing 44 and the support sleeve 45. The second bearing 44 is used to assist in supporting the left and right telescopic movement of the telescopic door 2. The telescopic door 2 is fixedly supported by the rotating outer ring of the second bearing 44, thereby greatly reducing the friction force on the telescopic door 2 during the movement, thereby improving the movement flexibility of the telescopic door 2; during the left and right telescopic sliding of the telescopic door 2, the slide rail 22 can move freely in the interval space between the fixed plate 42 and the second bearing 44, and the second bearing 44, the fixed plate 42 and the support sleeve 45 will not hinder the left and right movement of the slide rail 22, thereby ensuring the left and right movement of the telescopic door 2.

[0021] In actual applications, the slide rail 22 can be a built-in dual-axis linear guide, and the slide seat 5 can be a roller locking slider. The built-in dual-axis linear guide and the roller locking slider are both known technical products in the prior art and the combined use scenarios of the two are also widely present. Therefore, the specific structure of the built-in dual-axis linear guide and the roller locking slider and the specific combination relationship of the two will not be described in detail here.

[0022] In the present utility model, "upper", "lower", "front", "back", "left", "right", "inside" and "outside" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0023] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0024] The above description in combination with the accompanying drawings has detailed the preferred implementation modes and embodiments of the utility model, but the utility model is not limited to the above implementation modes and embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the concept of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
