TECHNICAL FIELD
[0001] The utility model relates to the technical field of protective cover, specifically to a half -closed protective cover with telescopic mechanism. BACKGROUND
[0002] A protective cover is a device used to protect equipment, personnel, or the environment from specific risks or hazards, usually made of metal, plastic, or other materials. It can be a physical barrier to prevent objects from flying out or entering a certain area, or a material used to absorb or block specific types of energy (such as light, sound, electromagnetic waves, etc.). A half -closed protective cover is a partially closed protective device that does not completely close a certain area, but provides some degree of protection. In industrial equipment, a half -closed protective cover can protect operators from mechanical parts while allowing operators to perform necessary operations or observe the running status of the equipment.
[0003] The lack of corresponding structure between the protective cover and the equipment makes the protective cover and the equipment not contact and collide, resulting in damage. For example, the patent with publication number CN219438718U discloses a protective cover, which is provided with a glass cover, and the bottom of the glass cover is provided with a U-shaped frame. The glass cover is attached to a glass plate on one side, and the bottom of the glass plate is provided with a connecting frame. The glass plate is attached to the glass cover on one side, and the connecting frame is connected to the U-shaped frame on one side. The top of the glass cover is provided with a connecting assembly, and the end of the connecting assembly away from the glass cover is rotatably connected to the top of the glass plate. First fixing assemblies are installed on the front and rear sides of the glass cover inside and below the glass plate, so that the equipment and the glass cover will not contact each other when they move, which avoids damage to the equipment, glass cover and glass plate.
[0004] The rope is connected to the equipment, which avoids damage to the equipment, glass cover and glass plate. However, in the prior art, the protective cover is usually manually folded or pulled to achieve telescopic extension, which cannot be fixed after telescopic extension, so that the telescopic part may not be stable, and thus may be extended or retracted, which affects the protective effect. Therefore, in order to solve the above problems, a half -closed protective cover with telescopic mechanism is proposed. SUMMARY
[0005] The utility model discloses a half -closed protective cover with telescopic mechanism to solve the problem that the telescopic part can not be fixed well after the telescopic operation of the protective cover, which can not be stable enough and can be extended or retracted easily, thereby affecting the protection effect.
[0006] In order to realize the above object, the utility model provides the following technical scheme: a half -closed protective cover with telescopic mechanism, including cover body, the cover body includes the mounting seat, the surface of mounting seat is provided with first protective cover, the inboard of first protective cover is swinged in connection with second protective cover, the inboard of second protective cover is swinged in connection with third protective cover;

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The first limiting rod can engage and disengage with different first limiting slots, enabling the movement and fixation of the second protective cover. The second limiting rod can engage and disengage with different second limiting slots, enabling the movement and fixation of the third protective cover. Furthermore, the second and third protective covers can be extended as needed, facilitating their fixation in the required positions. This ensures that the second and third protective covers are not easily moved after extension and retraction, guaranteeing the overall stability of the protective cover's extension and retraction, and thus improving the protective effect.
[0015] 2. The positioning rod and positioning groove provide positioning for the mounting base and the first protective cover during installation, ensuring installation accuracy and making installation more convenient. Simultaneously, the insertion rod moves within the movable groove, and in conjunction with the elasticity of the third spring, allows the insertion rod to engage and disengage with the slot, thereby enabling the fixing and unfixing of the positioning rod and the mounting base. This facilitates the installation and disassembly of the mounting base and the first protective cover, making the use of the first protective cover easier. Attached Figure Description
