Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a belt pulley protection casing with adjustable, including mounting panel 1 and the protecting crust 2 that is used for protecting the belt pulley, mounting panel 1 is the cuboid board that is on a parallel with vertical plane, and the vertical fixation is equipped with back shaft 44 in the middle of the mounting panel 1, and back shaft 44 passes in the middle of the bottom surface of protecting crust 2 perpendicularly to rotate with protecting crust 2 and be connected.

Referring to fig. 1, the protective casing 2 is a waist-shaped casing with a single side opened, and the protective casing 2 includes a waist-shaped bottom panel 25 parallel to a vertical plane, arc panels 26 fixedly connected to both sides of the bottom panel 25, and two plane panels 27 connected to the arc panels 26. The protective shell 2 is uniformly divided into three shell units 24 in the length direction, and the three shell units comprise a left shell 21, a middle shell 22 and a right shell 23 from left to right in sequence.

Referring to fig. 1, the left housing 21 is slidably fitted over the outer side of the middle housing 22 along the long side direction of the protective case 2, and the right housing 23 is slidably fitted over the inner side of the middle housing 22 along the long side direction of the protective case 2. The plane plates 27 of the three shell units 24 are all provided with adjusting grooves 31, and the adjusting grooves 31 are waist-shaped through grooves parallel to the long edges of the protective shell 2. When the left shell 21 and the right shell 23 slide along the middle shell, the adjusting grooves 31 of the two adjacent shell units 24 can be completely overlapped. The adjustment groove 31 is provided with a slide lock 3. The slide lock member 3 includes a slide lock nut 33 and a slide lock screw 32, and the slide lock screw 32 penetrates through the adjacent two housing units 24 to press the two housing units 24 between the slide lock nut 33 and the slide lock screw 32. The bottom panel 25 of the left shell 21 and the bottom panel 25 of the right shell 23 are provided with sliding slots 34 parallel to the direction of the adjusting slot 31, and the width of the sliding slots 34 is equal to the length of the rotating slot 41.

When the length of the shell 2 needs to be adjusted, the sliding lock nut 33 is rotated reversely, so that the left shell 21 and the right shell 23 slide in the middle shell 22 along the direction of the adjusting groove 31, and the sliding lock nut 33 is tightly abutted against the inner wall of the middle shell 22 after the length is adjusted. When the left and

right housings

21 and 23 slide along the middle housing 22, the rotation lock nut 43 moves in the slide groove 34. After the length of the casing 2 is determined, the slide lock nut 33 is turned to abut against the inner wall of the middle case 22, and the slide lock nut 33 and the slide lock screw 32 fix the left and

right cases

21 and 23 to the middle case 22.

Referring to fig. 1 and 3, the support shaft 44 is coupled to the middle housing 22. The bottom panel 25 of the middle shell 22 is provided with two circular arc-shaped rotating grooves 41, and the centers of the two rotating grooves 41 are on the axis of the supporting shaft 44. Two bracket grooves 45 with initial positions coincident with the rotating grooves 41 are formed in the bracket plate 1.

When the angle needs to be adjusted, the locking nut 43 is rotated in the reverse direction, so that the protective shell 2 rotates around the supporting shaft 44, and after the angle is adjusted, the locking nut 43 is tightly pressed against the inner wall of the middle shell 22.

Referring to fig. 1 and 2, a support plate 5 is fixedly installed at the bottom of the support plate 1, the support plate 5 is a rectangular plate parallel to the horizontal plane, and a pulley assembly 74 is fixedly connected to the bottom surface of the support plate 5. The pulley assembly 74 comprises an expansion link 6, a pulley bracket 71 and pulleys 7, wherein the expansion link 6 is vertically and fixedly connected to the bottom surface of the support plate 5 near four top corners. The telescopic bar 6 includes a fixed bar 61 and a sliding bar 62. One end of the fixing rod 61 is fixed at one end of the bottom surface of the supporting plate 5 and is provided with an accommodating groove 64 along the vertical direction, and the sliding rod 62 slides along the accommodating groove 64 in the vertical direction. The side wall of the fixed rod 61 is provided with a lifting locking screw 63, and the lifting locking screw 63 passes through the side wall of the fixed rod 61 and abuts against the outer wall of the sliding rod 62.

Before the use, when the height of protection casing was confirmed, rotatory lift locking screw 63 supported lift locking screw 63 tightly at the slide bar 62 outer wall. The friction between the sliding rod 62 and the fixing rod 61 is increased to determine the height of the shield case 2. When the height of the pulley is different from that of the shield, and the height of the shield needs to be adjusted, the lifting locking screw 63 is rotated reversely, the friction force between the sliding rod 62 and the fixing rod 61 is reduced, and the position of the sliding rod 62 in the accommodating groove 64 can be adjusted up and down.

Referring to fig. 2, the roller bracket 71 is fixedly connected to the bottom of the sliding rod 62, the two roller brackets 71 are parallel to the side wall of the bracket plate 1, and the roller 7 is rotatably connected to the roller 71 bracket. A fixing screw 72 and a fixing nut 73 screwed to the outside of the fixing screw 72 are rotatably connected to the center of the roller 7. The fixing screw 72 passes through the roller bracket 71 and the roller 7 in sequence, and the roller bracket 71 is pressed against the side wall of the roller 7 through the cooperation of the fixing screw 72 and the fixing nut 73.

When the position of the protective cover needs to be fixed, the fixing nut 73 is rotated to enable the fixing nut 73 to abut against the roller bracket 71, the outer side of the roller bracket 71 is pressed by the fixing nut 73 to abut against two side walls of the roller 7, and therefore friction force between the roller 7 and the roller bracket 71 is increased, and the roller 7 can be static relative to the ground. When it is desired to move the position of the shield, the fixing nut 73 is rotated in the reverse direction. The frictional force between the roller 7 and the roller bracket 71 is reduced and the roller 7 rolls with respect to the ground.
