At the same time, the spring 5 is used to connect the movable connecting piece 4 and the movable seat 3 respectively. When the movable connecting piece 4 moves away from the movable seat 3 to expose the cavity of the casing 1, the spring 5 will be deformed to form an elastic restoring force. As long as the operation on the cover 2 is released, the elastic force of the spring 5 can drive the movable connecting piece 4 together with the cover 2 to return to the original position. The cooperation of the limiting portion 31 and the guiding portion 41 can well ensure that the movable connecting piece 4 can only move stably along the plane of the movable seat 3. Therefore, it can be ensured that the operating cover 2 can be opened and closed by moving the cavity of the casing 1, thereby eliminating the need for the traditional inconvenient cover assembly and disassembly operation method. At the same time, the cover 2 can remain movably connected to the casing 1 to avoid separation, resulting in the defect that the cover is easily lost or damaged when opened and cannot be closed again. Moreover, the cover 2, the movable connecting piece 4, the mounting seat 3 and the casing 1 of the present scheme can be conveniently assembled and connected according to the actual structure or application requirements, making the production process very convenient.

[0022] refer to Figure 3 and 4The limiting portion 31 is a C-shaped groove protruding on one side of the movable seat 3 corresponding to the movable connecting member 4. The limiting portion 31 has two radial notches facing each other, and the two limiting portions 31 are respectively located on both sides of the movable seat 3. The guiding portion 41 is a sliding edge distributed on both sides of the movable connecting member 4 and correspondingly matched with the limiting portion 31. When the movable connecting member 4 is movably connected to the movable seat 3, the guiding portions 41 on both sides of the movable connecting member 4 slide axially along the C-shaped groove of the limiting portion 31 accordingly. At this time, the movable The two sides of the movable connecting member 4 are clamped by the movable seat 3, and the guide portion 41 on each side is clamped by the limiting portion 31, thereby limiting the movable connecting member 4 to move only along the surface of the movable seat 3 and only in one direction along the axial direction of the limiting portion 31. At the same time, the spring 5 connects the movable connecting member 4 and the movable seat 3 respectively, so the movable connecting member 4 cannot be easily separated from the movable seat 3. Conventionally, the limiting portion 31 and the guide portion 41 can also be common matching slide rail and slider structures, or matching track groove and slider structures.

[0023] refer to Figure 1-4 The limiting portion 31 is a C-shaped groove extending along a straight line, and the guiding portion 41 is also a straight edge corresponding to the limiting portion 31, and the length of the guiding portion 41 is greater than the length of the limiting portion 31. Therefore, the cooperation between the limiting portion 31 and the guiding portion 41 ultimately allows the cover body 2 to move back and forth in only one direction and in a straight line through the movable connecting member 4. Since the limiting portion 31 and the guiding portion 41 are long and straight, the two can remain stable without deflection during relative movement. Moreover, the guiding portion 41 is relatively long, which makes it easier for the movable connecting member 4 to connect and install with the movable seat 3 during assembly. At the same time, the cover body 2 also blocks the guiding portion 41 and the limiting portion 31 at the same time due to its large area structure, thereby maintaining the external aesthetics of the product. In addition, the limiting portion 31 and the guiding portion 41 can also be respectively matched to be arranged in a shape extending along a curve, thereby realizing non-unidirectional planar movement of the cover body.

[0024] refer to Figure 3 and 4 A slide groove member 32 is further provided between the limiting portion 31 and the guide portion 41. The slide groove member 32 is matchedly placed in the limiting portion 31, and the slide groove member 32 is provided with a sliding clamping groove matching and slidingly connecting the guide portion 41. The slide groove member 32 is preferably made of a material with a low friction coefficient, thereby reducing the sliding friction. The slide groove member 32 can further reduce the active gap when the movable connecting member 4 is movably connected to the movable seat 3, thereby minimizing the shaking of the cover body 2 caused thereby, and can reduce the processing accuracy of the movable seat 3, thereby helping to reduce production difficulty and improve efficiency.

[0025] refer to Figure 1 and 3A limiting recess 11 matching the movable seat 3 is provided on the front side surface of the casing 1, and the end surfaces of the leading and trailing ends of the slide member 32 correspond to the inner wall surface of the limiting recess 11, and when the movable seat 3 is connected to the casing 1, the position of the sliding clamping groove of the slide member 32 is higher than the front side surface of the casing 1. Therefore, when the movable seat 3 is installed on the slide member 32, the limiting recess 11 simultaneously limits the movable seat 3 and the slide member 32, and at the same time has a conflict or interference with the movable connecting member 4, ensuring the fixation and stability of each component.

[0026] refer to Figure 1 and 2 A straight bar protrusion 13 parallel to the limiting portion 31 is provided on the front side of the casing 1, and a straight groove 21 matching the straight bar protrusion 13 is provided on the rear side of the cover body 2. When the straight bar protrusion 13 is placed in the straight groove 21, the cover body 2 can directly obtain a movable limit on the casing 1 in the same direction as the moving direction, thereby making the movement of the cover body 2 more stable and further preventing the movable connecting member 4 and the movable seat 3 from being subjected to the deflection torque that may be generated when the cover body 2 is manually operated.

[0027] refer to Figure 1-4 The spring 5 is a torsion spring, and the spring 5 is located between the rear side of the movable connecting piece 4 and the front side of the movable seat 3. The two ends of the spring 5 are respectively connected to the rear side of the movable connecting piece 4 and the front side of the movable seat 3. The torsion spring can save space well and is arranged on the rear side of the movable connecting piece 4 and the front side of the movable seat 3, thereby saving structural space and reducing the space occupied by this structure on the product. Moreover, the torsion spring can realize unidirectional or multi-directional planar movement, while ordinary linear telescopic springs are generally only used for unidirectional linear motion connections, and additional structures are required to realize multi-directional planar motion, such as simultaneous rotation and movement on a plane. At the same time, the linear telescopic spring also needs to occupy more space.

[0028] refer to Figure 2-4 Both ends of the spring 5 are provided with rings 51, the rear side surface of the movable connecting piece 4 is provided with a front cylindrical protrusion 42 matching the ring 51, and the front side surface of the movable seat 3 is provided with a rear cylindrical protrusion 33 matching the ring 51. When connected, the spring 5 is connected through the ring 51 so that the two ends can rotate around the front cylindrical protrusion 42 or the rear cylindrical protrusion 33 respectively, and will not be stuck so that the torsion spring cannot apply force correctly. At the same time, when assembling the movable connecting piece 4 and the movable seat 3, you only need to connect the springs 5 ​​separately and then combine the connecting piece 4 and the movable seat 3 along the limiting portion 31 and the guide portion 41.

[0029] refer to Figure 1-4A positioning protrusion 22 is provided on the rear side surface of the cover body 2, and the movable connecting member 4 is provided with a positioning hole 43 corresponding to the positioning protrusion 22. A positioning boss 12 is provided on the casing 1, and the movable seat 3 is provided with an alignment hole 34 matching the alignment boss 12. Therefore, when assembling, when the movable connecting member 4 is connected to the cover body 2, or when the movable seat 3 is connected to the casing 1, they can be positioned and aligned respectively first, and then fixedly connected by means of snap connection, screw connection, clamping, etc.

[0030] refer to Figure 1-4 The movable connecting member 4 and the movable seat 3 are made of metal sheets. The movable connecting member 4 is provided with a connecting hole 44 for connecting with the cover body 2 by bolts or screws. The movable seat 3 is provided with a screw hole 35 for connecting with the casing 1 by bolts or screws. The movable connecting member 4 and the movable seat 3 made of metal sheets have better structural strength and durability. When assembling, the cover body 2 and the movable connecting member 4 can be connected in sequence first, and then the spring 5, the movable connecting member 4 and the movable seat 3 can be connected into a module, and then the casing 1 can be penetrated with bolts or screws from the rear side of the casing 1 and connected to the movable seat 3.
