[0005] The utility model discloses a picosecond laser appearance upper cover opening and closing and locking structure, which improves the stability and reliability of the upper cover when opening during use.

[0006] Further, the positioning plate has two and is symmetrically arranged on the lower sides of the upper cover.

[0007] Further, the guide groove has a plurality of.

[0008] Further, the guide groove includes a clamping groove and a step part, the clamping groove is matched with the positioning block, the upper cover is positioned and prevented from moving, the step part is matched with the positioning block, the clamping groove is matched with the positioning block when the upper cover moves on the step part, and the step part is used for supporting the upper cover when the upper cover and the shell body are separated.

[0009] Further, the clamping groove and the positioning block have an included angle of 40-60° in the horizontal direction.

[0010] Further, the shell is further provided with a locking portion for locking the upper cover. The locking portion can be any one of a compression ring, a screw port, a buckle or magnetic attraction. The reliable locking function of the locking portion effectively prevents accidental opening of the upper cover, improving the safety and reliability of the product. BRIEF DESCRIPTION OF DRAWINGS

[0014] In order to further understand the content of the utility model, the utility model will be described in detail below in combination with the drawings. EMBODIMENT

[0015] The embodiment provides a picosecond laser instrument shell as shown in Figure 1 and 2 The picosecond laser instrument shell comprises a shell 1 and an upper cover 2 arranged on the shell 1, and a positioning plate 3 is further arranged below the upper cover 2, a guide groove 4 is arranged on the positioning plate 3, and the guide groove 4 is matched with a positioning block 5 arranged on the shell 1. The positioning plate 3 in the embodiment has two and is symmetrically designed on the lower sides of the upper cover 2. On the positioning plate 3, the designed guide groove 4 has a plurality of.

[0016] The guide groove 4 in the embodiment comprises a clamping groove 6 and a step portion 7, the clamping groove 6 has an included angle of 40-60 ° in the horizontal direction, preferably 45 °. The positioning block 5 also has an included angle of 40-60 ° in the horizontal direction, preferably 45 °, and the clamping groove 6 and the positioning block 5 are matched with an inclination, so that when the shell 1 and the upper cover 2 are clamped or separated, as long as a force is given to the upper cover 2 in the horizontal direction, the upper cover 2 and the shell 1 can be easily clamped or separated.

[0017] When the upper cover 2 is moved, the clamping groove 6 and the positioning block 5 can be positioned and prevented from moving; when the step portion 7 and the positioning block 5 are matched, the upper cover 2 is moved on the step portion 7, so that the clamping groove 6 and the positioning block 5 are easily matched. When the upper cover 2 and the shell 1 are separated, the upper cover 2 is used to support the upper cover 2, so that the upper cover 2 and the shell 1 are separated from the clamping, and the upper cover 2 can be easily lifted.

[0018] The shell 1 is further provided with a locking portion 8 for locking the upper cover. The locking portion 8 can be any one of a press ring, a screw ring, a buckle or magnetic attraction. The reliable locking function of the locking portion 8 effectively prevents the accidental opening of the upper cover 2, and improves the safety and reliability of the product.

[0019] In actual application, when the user needs to open the upper cover 2, the locking portion 8 is first loosened, and then the upper cover 2 is gently pushed, so that the guide groove 4 guides the upper cover 2 to be smoothly opened. When the upper cover 2 is closed, the guide groove 4 also automatically guides the upper cover 2 to fall to the locking position, and the upper cover 2 is locked on the base by the locking portion 8, so that the upper cover 2 cannot be accidentally opened.

[0020] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
