It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] like Figures 1 to 7 As shown, the present invention provides a clamping tool for laying refractory bricks, including an outer box 1. A handle 2 is fixedly connected to the top of the outer box 1. A push rod 3 is movably connected to the bottom of the handle 2. A first inclined block 4 is fixedly connected to the top of the push rod 3. Second inclined blocks 5 located at the left and right ends of the first inclined block 4 are movably connected to the inside of the handle 2. A first connecting rod 6 is hinged to the opposite ends of the two second inclined blocks 5. A second connecting rod 7 is hinged to the bottom end of the first connecting rod 6. A movable plate 8 is movably connected to the inside of the outer box 1. A limit rod 9 is fixedly connected to the bottom of the movable plate 8. A rotating assembly 10 is provided inside the outer box 1.

[0036] The rotating assembly 10 comprises a cylindrical cam 1001 movably connected inside the outer box 1, and a surrounding guide groove 1002 is formed on the inner wall of the cylindrical cam 1001;

[0037] The outer wall of the cylindrical cam 1001 is fixedly connected with a gear 11, the inside of the outer box 1 is movably connected with a first toothed plate 12 and a second toothed plate 13, the bottom of each of the first toothed plate 12 and the second toothed plate 13 is provided with a clamping assembly 14, and the front and rear sides of the outer wall of the outer box 1 are both provided with a scale 15.

[0038] By pressing the push rod 3, the first inclined block 4 is used to extrude the two second inclined blocks 5 to move towards each other, then the second inclined blocks 5 are used to push the first connecting rod 6 to rotate around the shaft, the second connecting rod 7 is used to drive the moving plate 8 and the limiting rod 9 to move downwards, when the limiting rod 9 moves downwards, the protrusions on the outer wall of the limiting rod 9 slide along the track of the guide groove 1002, so as to drive the cylindrical cam 1001 and the gear 11 outside the cylindrical cam 1001 to rotate clockwise, then the gear 11 is used to mesh with the first toothed plate 12 and the second toothed plate 13, so as to drive the first toothed plate 12 and the second toothed plate 13 to move towards each other, and then the two clamping plates 1401 are used to move towards each other, when the gasket 1402 abuts against the outer wall of the firebrick, the handle 2 is lifted upwards at the same time when the push rod 3 is pressed, so as to achieve the effect of clamping the firebricks with different lengths in a certain length range.

[0039] Necessary: the contact surfaces of the first inclined block 4 and the two second inclined blocks 5 have sufficient width, and the handle 2 also has a cavity with sufficient height and width, in order to ensure the accuracy of the movement of the first inclined block 4 and the two second inclined blocks 5 towards each other, the contact surfaces of the first inclined block 4 and the two second inclined blocks 5 can guide each other, for example, the first inclined block 4 includes a straight protrusion at the contact surface, and the two second inclined blocks 5 correspondingly include straight grooves matched with the straight protrusion;

[0040] The first inclined block 4 moves in the vertical direction, and the two second inclined blocks 5 move in the horizontal direction;

[0041] The first connecting rod 6 is connected to a shaft, and the first connecting rod 6 can rotate around the shaft;

[0042] It should be emphasized that, in order to ensure that the second inclined block 5 pushes the first connecting rod 6 to rotate around the shaft, and the second connecting rod 7 drives the moving plate 8 to move downwards, the hinge mode of the second inclined block 5 and the first connecting rod 6 needs to ensure that the first connecting rod 6 rotates while the second inclined block 5 does not move up and down, for example, the hinge mode is that the first connecting rod 6 has a sliding groove, and the hinge piece of the second inclined block 5 and the first connecting rod 6 can slide in the sliding groove; correspondingly, the hinge mode of the first connecting rod 6 and the second connecting rod 7 needs to ensure that the first connecting rod 6 rotates while the second connecting rod 7 does not move horizontally, for example, the hinge mode is that the first connecting rod 6 has a second sliding groove, and the second hinge piece of the first connecting rod 6 and the second connecting rod 7 can slide in the second sliding groove;

[0043] The protrusions of the outer wall of the limiting rod 9 need to match the track of the guide groove 1002 to ensure that the protrusions can smoothly slide in the guide groove 1002.

[0044] As shown in Figures 1 to 4 , the clamping assembly 14 comprises clamping plates 1401, the opposite sides of each of the two clamping plates 1401 are fixedly connected with gaskets 1402 made of rubber material, and the front and rear ends of the top of each clamping plate 1401 are fixedly connected with pointers 1403.

[0045] By adopting the above scheme: the gaskets 1402 are made of rubber material, which can play a certain buffering role because the rubber material has elasticity, and when the device clamps the firebrick, the gaskets 1402 can buffer the extrusion force of the device on the firebrick, thereby preventing the firebrick from being damaged, and at the same time, the surface of the rubber material has a certain friction, so that the clamping force of the clamping plate 1401 on the firebrick can be improved, thereby preventing the firebrick from sliding or falling off during clamping.

[0046] As shown in Figures 1 to 5 , the top of the clamping plate 1401 is fixedly connected with a round rod, the bottom of the outer box 1 is provided with a straight slot for limiting the round rod, the bottom of the outer box 1 is provided with a protrusion, the clamping plate 1401 penetrates through the outer wall of the outer box 1 and extends to the outside of the outer box 1, the opposite sides of the two pointers 1403 are in abutment with the outer wall of the outer box 1, the bottom end of the push rod 3 penetrates through the outer wall of the handle 2 and extends to the outside of the handle 2, the push rod 3 is T-shaped, the two ends of the first inclined block 4 are inclined, the opposite ends of the two second inclined blocks 5 are inclined, the opposite ends of the two second inclined blocks 5 are in abutment with the two ends of the first inclined block 4, and the first inclined block 4 is moved upward to press the two second inclined blocks 5 to move in opposite directions, the second connecting rod 7 extends to the inside of the outer box 1, and the bottom ends of the two second connecting rods 7 are fixedly connected with the moving plate 8.

[0047] By adopting the above scheme: through the design of the pointers 1403, the clamping plate 1401 moves while driving the pointers 1403 to move in the same direction, when the gaskets 1402 are in abutment with the outer wall of the firebrick, the two pointers 1403 are moved to the predetermined position, and then the length of the clamped firebrick can be obtained through the scale of the two pointers 1403 on the scale 15, thereby improving the efficiency of construction.

[0048] As shown in Figures 3 to 4 , Figures 6 to 7As shown, the protrusions of the outer wall of the limiting rod 9 are movably clamped in the inner part of the guide groove 1002, when the limiting rod 9 moves downward, the protrusions slide along the track of the guide groove 1002, and drive the cylindrical cam 1001 to rotate clockwise; the outer part of the limiting rod 9 movably sleeves the spring 1003, the two ends of the spring 1003 are fixedly connected with the moving plate 8 and the cylindrical cam 1001 respectively, the spring 1003 is used for pressing the moving plate 8, and the moving plate 8 keeps the tendency of upward movement, and the opposite sides of the first toothed plate 12 and the second toothed plate 13 are all engaged with the gear 11, when the gear 11 rotates counterclockwise, the first toothed plate 12 and the second toothed plate 13 move towards each other.

[0049] By the spring 1003 supporting the moving plate 8, when the refractory bricks are carried to the predetermined position, the operator releases the pressing on the push rod 3, so that the first inclined block 4 releases the pressing on the two second inclined blocks 5, at this time, the moving plate 8 drives the limiting rod 9 to move upward under the action of the spring 1003, the limiting rod 9 moves upward, at the same time, the cylindrical cam 1001 and the gear 11 outside the cylindrical cam 1001 are driven to rotate reversely through the guide groove 1002, so as to drive the first toothed plate 12 and the second toothed plate 13 to move reversely, then the two clamping plates 1401 move reversely, and the clamping on the refractory bricks is released, at the same time, the moving plate 8 drives the second connecting rod 7 to move upward, then the second connecting rod 7 drives the two second inclined blocks 5 to move towards each other through the first connecting rod 6, and then the push rod 3 and the first inclined block 4 are reset under the action of the external force, which is convenient for the operator to use next time.

[0050] It is worth noting here that the middle scale of the scale 15 is zero, and the numbers are marked in sequence from left to right and right to left with the middle zero as the center, then the two pointers 1403 move towards each other, and the length of the clamped refractory brick can be obtained by calculating the value.

[0051] The working principle and use process of the present application are as follows: the operator places the device above the refractory bricks to be clamped, then the outer box 1 abuts against the top of the refractory bricks, the operator presses the push rod 3 towards the inside of the handle 2, so as to drive the first inclined block 4 to move upward, at the same time, the first inclined block 4 presses the two second inclined blocks 5 to move reversely, then the second inclined blocks 5 drive the second connecting rod 7 to move downward through the first connecting rod 6, and then the second connecting rod 7 drives the limiting rod 9 to move downward through the moving plate 8, at the same time, the protrusions on the two sides of the limiting rod 9 slide along the track of the guide groove 1002, so as to drive the cylindrical cam 1001 to rotate;

[0052] When the cylindrical cam 1001 rotates, the gear 11 outside the cylindrical cam 1001 rotates clockwise, and then the gear 11 drives the first toothed plate 12 and the second toothed plate 13 to move towards each other through meshing, thereby moving the two clamping assemblies 14 towards each other; when the gaskets 1402 abut against the outer wall of the firebrick, the operator continues to press the push rod 3, so that the gaskets 1402 generate frictional resistance on the outer wall of the firebrick, and then the operator holds the push rod 3 and lifts the handle 2 upwards, thereby clamping and carrying the firebrick;

[0053] When the clamping plates 1401 move, the pointers 1403 at the top of the clamping plates 1401 move towards the same direction; when the two gaskets 1402 abut against the outer wall of the firebrick, the pointers 1403 move to the corresponding scale values on the scale 15, and then the operator calculates the value between the two pointers 1403 to obtain the length of the clamped firebrick.

[0054] The gear 11 outside the cylindrical cam 1001 reversely rotates, thereby driving the first toothed plate 12 and the second toothed plate 13 to move in opposite directions; then the two clamping plates 1401 move in opposite directions and release the clamping of the firebrick; the moving plate 8 moves upwards, thereby driving the second connecting rod 7 to move upwards; then the second connecting rod 7 drives the second inclined block 5 to move towards each other through the first connecting rod 6, thereby resetting the push rod 3 and the first inclined block 4 under the action of an external force, which is convenient for the operator to use next time.
