[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a sheet metal structure for an inner protective cover of a gantry milling machine, including a support base 1 and a protective cover 2. The protective cover 2 is disposed on the upper surface of the support base 1, and a clamping mechanism 3 is provided on the inner wall of the protective cover 2.

[0028] There are two clamping mechanisms 3. The two clamping mechanisms 3 include clamping grooves 31, clamping parts 32 and spring-back components 33. There are two clamping grooves 31, which are opened on the upper surface of the support base 1. There are two clamping parts 32, and the outer surfaces of the two clamping parts 32 are in contact with the inner walls of the clamping grooves 31. The spring-back components 33 are disposed on the inner walls of the clamping parts 32.

[0029] The rebound assembly 33 includes a sliding rod 331 and a first spring 332. The sliding rod 331 passes through the inner wall of the clamping member 32. Both ends of the sliding rod 331 are fixedly connected to the inner wall of the protective cover 2. There are two first springs 332. The two first springs 332 are sleeved on the outer surface of the sliding rod 331. One end of the first spring 332 is fixedly connected to the opposite side of the clamping member 32, and the opposite end of the first spring 332 is fixedly connected to the inner wall of the protective cover 2.

[0030] The lower surface of the protective cover 2 has a limiting groove 4, and there are four limiting grooves 4. The inner wall of the four limiting grooves 4 is slidably connected to the outer surface of the clamping part 32.

[0031] Specifically, simply place the protective cover 2 on the support base 1, and the clamping groove 31 will press against the inclined surface of the clamping member 32 and slide into the inside of the clamping groove 31, fitting tightly with the clamping groove 31. The whole process can be completed with one hand without tightening screws or finding tools, and even if the equipment vibrates or ages, the buckle will not loosen.

[0032] Furthermore, first, the clamping member 32 is aligned with the clamping groove 31. Then, the protective cover 2 is placed on the upper surface of the support base 1. At this time, the clamping groove 31 presses the inclined surface of the clamping member 32, causing the clamping member 32 to move to the opposite side along the inner wall of the limiting groove 4 and the outer surface of the sliding rod 331. At the same time, the first spring 332 can push the clamping member 32 to move to the opposite side until the distance between the clamping members 32 is equal to the distance between the clamping grooves 31. Only then can the clamping member 32 enter the interior of the clamping groove 31. At the same time, the clamping member 32 moves back until the outer surface of the clamping member 32 is tightly fitted with the inner wall of the clamping groove 31, thereby fixing the protective cover 2 on the upper surface of the support base 1.

[0033] Example 2

[0034] In the second embodiment of this utility model, a travel component 5 is provided on the upper surface of the clamping member 32. There are four travel components 5, each including a travel post 51, a travel rod 52, and a travel groove 53. The lower end face of the travel post 51 is fixedly connected to the upper surface of the clamping member 32. The travel rod 52 is provided on the outside of the travel post 51. The travel groove 53 is opened on the surface of the travel rod 52. The inner wall of the travel groove 53 is slidably connected to the outer surface of the travel post 51.

[0035] A support column 6 is provided on the inner wall of the stroke rod 52. Both the upper and lower ends of the support column 6 are fixedly connected to the inner wall of the protective cover 2. The outer surface of the support column 6 is rotatably connected to the inner wall of the stroke rod 52 through a bearing.

[0036] The outer surface of the stroke rod 52 is provided with a pressing component 7. There are two pressing components 7, each including a force-receiving wheel 71 and a pressing block 72. There are two force-receiving wheels 71. The inner walls of the two force-receiving wheels 71 are rotatably connected to the inner wall of the stroke rod 52 through a rotating shaft. The outer surface of the pressing block 72 is in contact with the outer surface of the force-receiving wheel 71.

[0037] Specifically, when the extrusion block 72 pushes the force wheel 71, the stroke rod 52 will rotate around the support column 6 as the fulcrum. The stroke groove 53 guides the stroke column 51 to slide like a track, so that the clamping part 32 and the clamping groove 31 fit tightly together. The whole process does not require manual adjustment of the angle, ensuring perfect fit every time.

[0038] Furthermore, in order to make the clamping member 32 fit tightly with the clamping groove 31, the force-receiving wheel 71 is squeezed by the extrusion block 72. The force-receiving wheel 71 drives the stroke rod 52 to rotate around the support column 6 as the rotation center. The stroke rod 52 then squeezes the stroke column 51 through the stroke groove 53 on its surface, causing the stroke column 51 to slide along the inner wall of the stroke groove 53. At the same time, the stroke column 51 drives the clamping member 32 to fit tightly with the clamping groove 31.

[0039] Example 3

[0040] In the third embodiment of this utility model, a pressing component 8 is provided on the upper surface of the extrusion block 72. There are two pressing components 8. The two extrusion components 7 include a pressing plate 81, a sliding groove 82, and a second spring 83. The lower surface of the pressing plate 81 is fixedly connected to the upper surface of the extrusion block 72. The sliding groove 82 is opened on the upper surface of the protective cover 2. The inner wall of the sliding groove 82 is connected to the outer surface of the extrusion block 72. One end of the second spring 83 near the pressing plate 81 is fixedly connected to the outer surface of the pressing plate 81, and the other end of the second spring 83 near the sliding groove 82 is fixedly connected to the inner wall of the sliding groove 82.

[0041] Specifically, simply pull the pressing plate 81 to stop the extrusion block 72 from extruding the force-bearing wheel 71, and at the same time, prevent the clamping part 32 from fitting with the clamping groove 31. At this time, the protective cover 2 can be removed. The process is simple and easy to operate.

[0042] Furthermore, in order to prevent the clamping member 32 from being tightly fitted with the clamping groove 31, the pressing plate 81 is pulled along the inner wall of the slide groove 82 to the opposite side. The pressing plate 81 can squeeze the second spring 83, so that the second spring 83 generates elastic force. The pressing plate 81 can drive the pressing block 72 to stop squeezing the force-bearing wheel 71. At this time, the first spring 332 releases its elastic force, pushing the clamping member 32 away from being tightly fitted with the clamping groove 31.

[0043] Working principle:

[0044] First, align the clamping member 32 with the clamping groove 31. Then, place the protective cover 2 on the upper surface of the support base 1. At this time, the clamping groove 31 presses against the inclined surface of the clamping member 32, causing the clamping member 32 to move along the inner wall of the limiting groove 4 and the outer surface of the sliding rod 331 to the opposite side. Simultaneously, the first spring 332 can push the clamping member 32 to the opposite side until the distance between the clamping members 32 is equal to the distance between the clamping grooves 31, allowing the clamping member 32 to enter the clamping groove 31. At the same time, the second spring 8... 3. Release the elastic force and push the pressing plate 81 to move along the inner wall of the slide groove 82 to the opposite side. The pressing plate 81 can drive the pressing block 72 to press the force wheel 71. The force wheel 71 drives the stroke rod 52 to rotate around the support column 6 as the rotation center. The stroke rod 52 then presses the stroke column 51 through the stroke groove 53 on the surface, so that the stroke column 51 slides along the inner wall of the stroke groove 53. At the same time, the stroke column 51 drives the clamping piece 32 to fit tightly with the clamping groove 31, so as to fix the protective cover 2 on the upper surface of the support base 1.

[0045] When the protective cover 2 needs to be removed, the pressing plate 81 is pulled along the inner wall of the slide groove 82 to the opposite side. The pressing plate 81 can squeeze the second spring 83, so that the second spring 83 generates elastic force. The pressing plate 81 can drive the pressing block 72 to stop squeezing the force wheel 71. The first spring 332 releases its elastic force and pushes the clamping part 32 to not be tightly fitted with the clamping groove 31. At this time, the protective cover 2 can be removed.

[0046] In summary, the combination of clamping mechanism 3, limiting groove 4, stroke component 5, support column 6, pressing component 7 and pressing component 8 solves the problem that installing multiple bolts not only requires repeated adjustments to ensure precise hole alignment, but also requires tightening each bolt individually with tools. With as few as four or five bolts and as many as seven or eight fixing points, the installation of the protective cover for a single piece of equipment often consumes a lot of time.
