DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] See attached Figure 1-3 A hydraulic mechanical processing equipment with a protective mechanism, comprising a hydraulic paper cutter housing 1, the hydraulic paper cutter is a hydraulic machine, a switch type protective mechanism 2 is installed at the cutting opening of the operating platform in the hydraulic paper cutter housing 1, and the switch type protective mechanism 2 includes a gate window and a cutting switch;

[0022] The gate window includes a slide rail 22, a slide frame 24 and a glass 26. The slide rail 22 is in an N-shape as a whole and is fixedly installed on the hydraulic paper cutter housing 1. The slide rail 22 is arranged just above the operating platform in the hydraulic paper cutter housing 1. Guide grooves 221 are arranged on the inner walls on both sides of the slide rail 22. The slide frame 24 is in a rectangular shape as a whole. Both sides of the slide frame 24 are vertically slidably installed in the guide grooves 221 through linear pulleys 27 respectively. The pulley frame in the linear pulley 27 is fixedly connected to the slide frame 24. The pulley in the linear pulley 27 is rollingly installed in the guide groove 221. The glass 26 is fixedly installed in the inner frame of the slide frame 24. That is, when the slide frame 24 moves vertically up and down along the slide rail 22 through two linear pulleys 27, the glass 26 will also move with the slide frame 24. After the slide frame 24 and the glass 26 move down, they are used to cover the cutting opening of the operating platform in the hydraulic paper cutter housing 1, which can effectively prevent the worker's fingers from being put into the cutting opening of the operating platform in the hydraulic paper cutter housing 1.

[0023] A buffer pad 25 is fixedly installed on the lower end surface of the slide 24, and the buffer pad 25 is made of natural rubber. A brake handle 28 is fixedly installed on the outer side of the lower end of the slide 24. The lower end of the brake handle 28 is rotatably connected to the slide 24 through a fixed block 282. The slide 24 is fixedly connected to the fixed block 282, and the fixed block 282 is rotatably connected to the brake handle 28. A pull rope 281 is provided between the slide 24 and the brake handle 28. The two ends of the pull rope 281 are fixedly connected to the slide 24 and the brake handle 28 respectively, and the pull rope 281 is used to limit the rotation angle of the brake handle 28.

[0024] A hanging rod 23 is fixedly installed on the outer end surface of the slide rail 22, and the upper end surface of the hanging rod 23 gradually tilts downward from the outside to the inside, and a clamping block 283 is fixedly installed on the inner end surface of the upper end of the handle 28, and the lower end surface of the clamping block 283 is provided with an inverted V-shaped groove, and the inverted V-shaped groove and the upper end of the hanging rod 23 are meshed with each other. The hanging rod 23 is horizontally arranged, and the worker uses the handle 28 to move the slide 24 and the glass 26 vertically upward along the two guide grooves 221 on both sides. When the worker moves upward over the hanging rod 23 on the outer side of the slide rail 22, the upper end of the handle 28 is manually moved close to the hanging rod 23, and the inverted V-shaped groove of the clamping block 283 on the inner side of the handle 28 is clamped on the upper end surface of the hanging rod 23, which is used to stably place the slide 24 and the glass 26 on the upper end of the cutting opening of the operating platform in the hydraulic paper cutter housing 1, that is, paper can be placed under the slide 24 and the glass 26.

[0025] In this embodiment, the cutting switch is composed of a plurality of static contacts 21 and a plurality of moving contacts 29. The plurality of static contacts 21 are all installed on the operating platform in the hydraulic paper cutter housing 1. The plurality of static contacts 21 are respectively vertically installed directly below the plurality of moving contacts 29. The plurality of moving contacts 29 are all fixedly installed on the lower end of the slide 24. The static contact 21 is composed of a copper column 1 211, a spring 212, a copper column 213 and a brass cover 214. The copper column 1 211 is fixedly connected to the hydraulic paper cutter housing 1. The copper column 213 is coaxially fixedly installed on the upper end of the copper column 1 211. The lower end inner cavity of the brass cover 214 is telescopically installed on the upper end of the copper column 213. The spring 212 is sleeved on the periphery of the copper column 213. The upper and lower ends of the spring 212 are squeezed and installed between the copper column 1 211 and the brass cover 214. The brass cover 214 uses the elastic deformation of the spring 212 to buffer the impact force generated by the falling of the moving contact 29.

[0026] As can be seen from the above, multiple moving contacts 29 can be opened and closed up and down with the slide 24, and are used to connect the circuits in multiple static contacts 21 and multiple moving contacts 29. The cutting switch in the present application is used to replace the switch of the hydraulic paper cutter cutting alloy blade in the prior art, that is, only when the slide 24 and the glass 26 move down to cover the cutting opening of the operating platform in the hydraulic paper cutter housing 1, the multiple static contacts 21 and the multiple moving contacts 29 can contact and connect the hydraulic paper cutter cutting alloy blade circuit, that is, after the cutting opening of the operating platform in the hydraulic paper cutter housing 1 is covered and protected by the glass 26, the alloy blade in the hydraulic paper cutter can operate, thereby effectively preventing workers from putting their fingers into the cutting opening of the operating platform in the hydraulic paper cutter housing 1.

[0027] When the utility model is in use, the worker moves the slide 24 and the glass 26 vertically downward along the two guide grooves 221 on both sides through the handle 28, and moves the glass 26 downward to cover the cutting opening of the operating platform in the hydraulic paper cutter housing 1. After the slide 24 is completely moved downward, the slide 24 can drive the multiple moving contacts 29 to respectively connect with the multiple static contacts 21 on the operating platform, so that the multiple static contacts 21 and the multiple moving contacts 29 can be connected to contact the hydraulic paper cutter cutting alloy blade circuit, that is, the alloy blade in the hydraulic paper cutter can only operate after the cutting opening of the operating platform in the hydraulic paper cutter housing 1 is covered and protected by the glass 26, thereby effectively preventing the worker's fingers from being put into the cutting opening of the operating platform in the hydraulic paper cutter housing 1, and fundamentally preventing the worker's palm from being put into the cutting opening when the hydraulic paper cutter is working, thereby protecting the worker's personal safety.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
