Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, and more specifically, to a frameless noise reduction protective cover. Background Technology

[0002] Machine tool guards are important components used to protect machine tools. They can prevent dust, chips, hard sand particles, etc. from entering the tracks, reduce damage to the sliding rail surface caused by hard particulate matter, and reduce the impact of guide rail deformation on machining accuracy.

[0003] Currently, protective covers mainly consist of a retractable accordion sleeve, combined armor plates, and an internal skeleton support plate. The accordion sleeve is flexible, folding and unfolding through creases, allowing it to extend and retract according to usage needs, preventing dust and other impurities from entering the machine tool. Support plates are evenly spaced inside the sleeve, forming the sleeve's skeleton and corresponding to the creases, providing support and ensuring stability during the accordion sleeve's extension and retraction. The combined armor plates are fixed to the accordion sleeve and unfold and fold along with its extension and retraction, providing strength and protecting the machine tool from external damage. However, existing protective covers rely on support plates for internal support. During extension and retraction, the accordion sleeve rubs against the support plate surface, easily generating significant noise and affecting the working environment. Furthermore, the combined armor plates are loosely installed on the accordion sleeve to accommodate its extension and retraction, resulting in insufficient contact between the armor plates after the accordion sleeve is stretched, leading to poor protective performance. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a frameless noise-reducing protective cover. This aims to solve the problem that in existing protective covers, the accordion-style cover is supported by a support plate, which causes friction and contact between the cover and the support plate surface during extension and retraction, easily generating significant noise and affecting the working environment. Furthermore, the modular armor plates are loosely installed on the accordion-style cover to accommodate its extension and retraction, resulting in insufficient contact between the armor plates after the cover is stretched, leading to poor protective performance.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A frameless noise reduction protective cover includes a frame, an accordion telescopic cover is provided inside the frame, and one side of the accordion telescopic cover is fixedly connected to one side wall of the frame. An armor plate is provided on the top of the frame and is fixedly connected to the upper side of the accordion telescopic cover.

[0009] The accordion telescopic cover includes multiple upper connecting parts and multiple sets of folding parts. The multiple upper connecting parts and multiple sets of folding parts are all arranged inside the frame. The outermost set of folding parts is fixedly connected to one side wall of the frame. Each pair of adjacent sets of folding parts is fixedly connected. Each set of folding parts consists of two parts, and each pair of two folding parts is fixedly connected to the bottom end of an upper connecting part.

[0010] The armor plate includes multiple lower connecting parts and multiple protective plates. The multiple lower connecting parts are fixedly connected to multiple upper connecting parts, and the multiple protective plates are fixedly connected to multiple lower connecting parts. The multiple protective plates are all located on the upper side of the frame and are distributed at equal intervals.

[0011] As a preferred embodiment of this utility model, each of the lower connecting parts is provided with a connecting port, and the multiple connecting ports correspond to the multiple upper connecting parts respectively.

[0012] As a preferred embodiment of this utility model, a plurality of connecting strips are fixedly connected inside the bellows telescopic cover, and the plurality of connecting strips are equidistantly distributed. One end of each of the plurality of connecting strips is rotatably connected to a roller, and the plurality of rollers are located on one side of the bellows telescopic cover. A slide rail is fixedly connected inside the frame, and the plurality of rollers are slidably connected inside the slide rail.

[0013] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to one side of the bellows telescopic cover.

[0014] As a preferred embodiment of this utility model, a limiting plate is fixedly connected to the top of the frame, and one end of each of the multiple protective plates is located inside the limiting plate.

[0015] As a preferred embodiment of this utility model, both ends of the frame are fixedly connected to connecting beams, and the two connecting beams are symmetrically distributed.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) In this solution, the bellows telescopic cover protects the machine tool by moving one end within the frame. The bellows telescopic cover consists of multiple upper connecting parts and multiple sets of folding parts. Each pair of adjacent sets of folding parts is fixedly connected, and the connection is strong, which can improve the strength of the bottom folding part of the bellows telescopic cover. The top of each set of folding parts is connected to the lower connecting part through the upper connecting part. The connection between the upper connecting part and the lower connecting part can improve the strength of the top folding part of each pair of folding parts. In this utility model, multiple sets of bellows telescopic covers are fixedly connected, and multiple upper connecting parts and multiple lower connecting parts are fixedly connected. The connection of multiple sets of folding parts, multiple upper connecting parts and multiple lower connecting parts can improve the strength of the folding part of the bellows telescopic cover, so that the bellows telescopic cover has good support and stability without the installation of support plates, ensuring the telescopic effect while reducing the noise generated by telescopic movement.

[0019] (2) In this solution, when the bellows telescopic cover is unfolded to protect the machine tool, multiple sets of folding parts will unfold. Each set of two folding parts will unfold at the bottom of an upper connecting part. During the unfolding of each set of two folding parts, an upper connecting part will be pulled to unfold. Multiple upper connecting parts will press one end of multiple protective plates downward through multiple lower connecting parts, thereby pressing one end of multiple protective plates downward in sequence, ensuring that the multiple protective plates of the armor plate always maintain close contact when unfolding with the bellows telescopic cover, thus improving the protection effect on the machine tool.

[0033] Example:

[0034] Please see Figure 1-8 A frameless noise reduction protective cover includes a frame 1, a bellows telescopic cover 2 is provided inside the frame 1, and one side of the bellows telescopic cover 2 is fixedly connected to one side wall of the frame 1. An armor plate 3 is provided on the top of the frame 1, and the armor plate 3 is fixedly connected to the upper side of the bellows telescopic cover 2.

[0035] The accordion telescopic cover 2 includes multiple upper connecting parts 21 and multiple sets of folding parts 22. The multiple upper connecting parts 21 and multiple sets of folding parts 22 are all disposed inside the frame 1. The outermost set of folding parts 22 is fixedly connected to one side wall of the frame 1. Each pair of adjacent sets of folding parts 22 is fixedly connected. Each set of folding parts 22 consists of two parts, and each pair of two folding parts 22 is fixedly connected to the bottom end of one upper connecting part 21.

[0036] The armor plate 3 includes multiple lower connecting parts 31 and multiple protective plates 32. The multiple lower connecting parts 31 are fixedly connected to multiple upper connecting parts 21, and the multiple protective plates 32 are fixedly connected to multiple lower connecting parts 31. The multiple protective plates 32 are all located on the upper side of the frame 1 and are distributed at equal intervals.

[0037] In this embodiment, the frame 1 is installed at the required protective position of the machine tool, so that the bellows telescopic cover 2 and the armor plate 3 correspond to the machine tool. Each group of two folding parts 22 is fixed to the bottom end of an upper connecting part 21. Each pair of adjacent folding parts 22 are fixedly connected to form a bellows telescopic cover 2. One end of the bellows telescopic cover 2 is fixed inside the frame 1, and the other end can slide inside the frame 1 to realize telescopic protection of the machine tool. During the telescopic process of the bellows telescopic cover 2, through the connection between multiple upper connecting parts 21 and multiple lower connecting parts 31, multiple protective plates 32 can telescopically extend and retract at the top of the frame 1. The multiple protective plates 32 follow the telescopic movement of the bellows telescopic cover 2 to protect the machine tool and prevent the machine tool from being damaged by external forces.

[0038] Specifically, each of the multiple lower connecting parts 31 has a connecting port 4, and the multiple connecting ports 4 correspond to the multiple upper connecting parts 21 respectively.

[0039] In this embodiment, the connector 4 can be used with screws to make the connection between the multiple upper connectors 21 and the multiple lower connectors 31 more stable.

[0040] Specifically, multiple connecting strips 5 are fixedly connected inside the bellows telescopic cover 2, and the multiple connecting strips 5 are evenly distributed. One end of each of the multiple connecting strips 5 is rotatably connected to a roller 6, and the multiple rollers 6 are all located on one side of the bellows telescopic cover 2. A slide rail 7 is fixedly connected inside the frame 1, and the multiple rollers 6 are slidably connected inside the slide rail 7.

[0041] In this embodiment, the accordion telescopic cover 2 will drive multiple connecting bars 5 to move during the telescopic process. The multiple connecting bars 5 cause multiple rollers 6 to slide within the slide rail 7. The sliding of multiple rollers 6 within the slide rail 7 keeps the telescopic cover 2 stable during telescopic movement within the frame 1.

[0042] Specifically, a connecting plate 8 is fixedly connected to one side of the accordion telescopic cover 2.

[0043] In this embodiment, the connecting plate 8 is used to connect the driving device, so that the driving device can move one end of the bellows telescopic cover 2 to achieve telescopic movement.

[0044] Specifically, a limiting plate 9 is fixedly connected to the top of the frame 1, and one end of each of the multiple protective plates 32 is located inside the limiting plate 9.

[0045] In this embodiment, the limiting plate 9 is used to restrict the multiple protective plates 32, so that the multiple protective plates 32 can stably move and retract above the frame 1 along with the accordion telescopic cover 2.

[0046] Specifically, both ends of the frame 1 are fixedly connected to connecting beams 10, and the two connecting beams 10 are symmetrically distributed.

[0047] In this embodiment, two connecting beams 10 are used to install and fix the frame 1, so that the frame 1 is stably aligned with the machine tool. At the same time, the two connecting beams 10 can also improve the strength of the frame 1.

[0048] Working principle: By installing the frame 1 at the position corresponding to the machine tool, when protecting the machine tool, by moving one end of the bellows telescopic cover 2, multiple sets of folding parts 22 and multiple upper connecting parts 21 cooperate to make the bellows telescopic cover 2 slide and unfold inside the frame 1. During the unfolding process, multiple upper connecting parts 21 drive multiple protective plates 32 to move through multiple lower connecting parts 31. Multiple protective plates 32 unfold above the frame 1 with the bellows telescopic cover 2 to protect the machine tool.
