[0029] Example 1 See also Figures 1 to 9 The present invention provides a block mortar joint control device, comprising a positioning frame 1 for moving on a wall, the positioning frame 1 comprising two L-shaped positioning rods 1-1 arranged opposite to each other, the two ends of the two positioning rods 1-1 are fixedly connected by a screw 1-2, the screw 1-2 is a double-headed screw 1-2, and two nuts are respectively threadedly connected on the threads at both ends of the screw 1-2, and the nuts are located on both sides of the positioning rod 1-1; A control plate 1-3 for controlling the thickness of the mortar joint is respectively arranged on the positioning rods 1-1. The shape of the control plate 1-3 corresponds to the shape of the positioning rods 1-1. The control plate 1-3 includes a horizontal part and a vertical part. The horizontal part is used to control the horizontal mortar joint of the block, and the vertical part is used to control the vertical mortar joint of the block. A sliding rod 1-4 is fixedly arranged on the horizontal part of each positioning rod 1-1, and a mortar spreading mechanism 2 for block plastering is slidably arranged on the sliding rod 1-4.

[0030] A plurality of slots are arranged on the rod body of the positioning rod 1-1, and a fixing unit 1-5 is fixedly arranged at each slot; The cross-sectional shape of the control board 1-3 is L-shaped, and the two ends of the control board 1-3 are fixedly connected by a plurality of reinforcing rods 1-6, each reinforcing rod 1-6 corresponds to one of the slots and is clamped with the fixing unit 1-5; The reinforcing rod 1-6 can improve the structural strength of the control panel 1-3, effectively preventing the control panel 1-3 from tilting or deforming during use. By means of the connection between the reinforcing rod 1-6 and the fixing unit 1-5, the control panel 1-3 can be quickly replaced in different processes. By replacing the control panel 1-3, the width of the mortar joint of the masonry blocks can be adjusted.

[0031] The mortar spreading mechanism 2 comprises a working frame 2-1 slidably connected to the slide bar 1-4, two upright posts 2-2 are fixedly arranged on the working frame 2-1, a slide 2-3 is slidably arranged on the two upright posts 2-2, and a scraper 2-4 for mortar spreading is fixedly arranged on the slide 2-3; A support frame 2-5 is also fixedly arranged on the working frame 2-1, a transfer seat 2-6 is rotatably arranged on the support frame 2-5, a pressure arm 2-7 is slidably arranged on the transfer seat 2-6, one end of the pressure arm 2-7 is rotatably connected to the slide 2-3, and a pressure handle is fixedly arranged on the other end; The working frame 2-1 is also fixedly provided with a limiting unit 2-8 for fixing the pressing arm 2-7, and two fastening units 2-9 for fixing the working frame 2-1, and each fastening unit 2-9 corresponds to one of the sliding rods 1-4.

[0032] When the slide 2-3 is at the lower end of the column 2-2, the mortar on the horizontal blocks can be spread by moving the work frame 2-1, and when the slide 2-3 moves upward along the column 2-2, the scraper 2-4 can spread the mortar on the vertical blocks; First, the user places a certain amount of mortar on the block. Through the sliding of the work frame 2-1, the scraper 2-4 can evenly spread the mortar on the surface of the block. When the scraper 2-4 needs to spread the mortar on the vertical block, the user applies appropriate pressure to the pressure arm 2-7, and the pressure arm 2-7 drives the slide 2-3 to move upward along the column 2-2, thereby spreading the mortar on the vertical block; through the coordinated action of the pressure arm 2-7 and the slide 2-3, the construction workers can quickly and accurately complete the mortar spreading of the vertical blocks, which significantly improves the work efficiency.

[0033] The fastening unit 2-9 includes a mounting plate 2-10 fixedly mounted on the work frame 2-1, a clamping arm 2-11 is rotatably mounted on both sides of the plate body of the mounting plate 2-10, the middle portion of the clamping arm 2-11 is rotatably connected to the mounting plate 2-10, and a clamping plate 2-12 is rotatably mounted on the lower end of the clamping arm 2-11; A control rod 2-13 is rotatably set in the middle of the mounting seat, and the control rod 2-13 is T-shaped. The middle of the horizontal part of the control rod 2-13 is rotatably connected to the mounting seat, and a connecting rod 2-14 is rotatably set at both ends of the horizontal part of the control rod 2-13. The movable end of each connecting rod 2-14 is rotatably connected to the upper end of an adjacent clamping arm 2-11.

[0034] When the user spreads mortar on the vertical blocks, the user first uses a fastening mechanism to fix the work frame 2-1 on the slide bar 1-4 to prevent the work frame 2-1 from loosening or shifting during the construction of the vertical blocks, thereby ensuring the control accuracy of the mortar joints of the vertical blocks; As the horizontal part of the control rod 2-13 rotates, the action of the connecting rod 2-14 causes the lower end of the clamping arm 2-11 to rotate and the clamping plate 2-12 to tightly clamp the sliding rod 1-4.

[0035] The limiting unit 2-8 includes a slide rail 2-15 fixedly arranged on the support frame 2-5, two limiters 2-16 are slidably arranged on the slide rail 2-15, and the two limiters 2-16 are arranged opposite to each other. A driving rod 2-17 is fixedly arranged at the lower end of each limiter 2-16, and a folding edge is fixedly arranged at the upper end of each limiter 2-16. The folding edge can further limit the pressure arm 2-7, thereby improving the use effect of the limiting unit 2-8; An active rod 2-18 is also rotatably arranged on the slide rail 2-15, the middle portion of the active rod 2-18 is rotatably connected to the slide rail 2-15, and both ends are rotatably connected to a connecting rod 2-19 respectively, and the movable end of the connecting rod 2-19 is rotatably connected to a driving rod 2-17 of an adjacent limiter 2-16.

[0036] When the user rotates the active rod 2-18, the active rod 2-18 drives the connecting rod 2-19 to rotate, and then drives the limiter 2-16 to slide along the slide rail 2-15. When the two slide rails 2-15 are far away from each other, the user can spread the mortar on the vertical blocks by pressing the pressure arm 2-7. When the two slide rails 2-15 are close to each other, the two limiters 2-16 limit the position of the pressure arm 2-7. At this time, the slide 2-3 is at the lower end of the column 2-2. By moving the working frame 2-1, the mortar on the horizontal blocks can be spread.

[0037] An active rack 2-20 is fixedly disposed on each stopper 2-16, and two gears 2-21 are rotatably disposed on the slide rail 2-15, and each gear 2-21 is meshed with an adjacent active rack 2-20; Two driven parts 2-22 are also slidably arranged on the slide rail 2-15, and a driven rack 2-23 is fixedly arranged on each driven part 2-22, and the driven rack 2-23 is meshed with the adjacent gear 2-21; Each follower 2-22 is connected to the upper end of the vertical portion of the adjacent control rod 2-13 through a control rod 2-24.

[0038] When the user adjusts the limit unit 2-8, the two limiters 2-16 are moved away from each other by rotating the active rod 2-18. Under the action of the active rack 2-20, the gear 2-21 and the driven rack 2-23, the two driven parts 2-22 move toward the side close to each other. Under the action of the connecting rod 2-14, the operation of the fastening unit 2-9 is realized. In this way, when the user performs vertical mortar paving, the fastening unit 2-9 can fix the slide bar 1-4 to ensure that the working frame 2-1 will not move left and right while the slide 2-3 moves up and down; When the user needs to perform horizontal mortar paving, the active rod 2-18 is rotated in the opposite direction to make the two limiters 2-16 approach each other. At this time, the limit unit 2-8 can limit the position of the pressure arm 2-7, and at this time, the fastening unit 2-9 cancels the fixation of the slide bar 1-4 to ensure that the slide 2-3 will not move up and down when the user is performing horizontal mortar paving, thereby ensuring the control of paving accuracy.

[0039] A handle 2-25 is rotatably arranged on the active rod 2-18, a cross bar 2-26 is fixedly arranged in the middle of the support frame 2-5, and a stop block 2-27 is fixedly arranged in the middle of the cross bar 2-26.

[0040] When the handle 2-25 is on one side of the stop block 2-27, the fastening unit 2-9 fixes the slide bar 1-4 to prevent the working frame 2-1 from moving during operation, and the limiting unit 2-8 removes the restriction on the pressing arm 2-7, so that the pressing arm 2-7 can rotate freely without interference from the limiting unit 2-8; When the handle 2-25 is on the other side of the stop block 2-27, the fastening unit 2-9 cancels the fixation of the slide bar 1-4, the working frame 2-1 can slide along the slide bar 1-4, and the limiting unit 2-8 limits the position of the pressure arm 2-7; When the user realizes the rotation of the active rod 2-18 through the handle 2-25, the user first turns the handle 2-25 to make the handle 2-25 higher than the stop block 2-27, and then turns the handle 2-25 to move the handle 2-25 to the other side of the stop block 2-27.

[0041] The clamping plate 2-12 is V-shaped, the closed end of the clamping plate 2-12 is rotatably connected to the clamping arm 2-11, and the open ends of the clamping plate 2-12 are respectively fixedly provided with rubber pads.

[0042] The V-shaped structure of the splint 2-12 and the use of the rubber pad effectively reduce the friction between the slide bar 1-4 and the splint 2-12. The rubber pad acts as a buffer between the splint 2-12 and the slide bar 1-4, which not only improves the fixing effect, but also reduces the wear that may occur during the long-term use of the equipment, thereby extending the service life of the equipment.

[0043] The fixing unit 1-5 includes a fixing seat 1-7 fixedly arranged on the positioning rod 1-1, a V-shaped fixing clamp 1-8 is fixedly arranged on the fixing seat 1-7, and a roller is rotatably arranged at the opening end of the fixing clamp 1-8.

[0044] Through the deformation of the fixing clamp 1-8, the reinforcement rod 1-6 can be inserted into the fixing clamp 1-8, so that the control board 1-3 and the positioning rod 1-1 are fixedly connected, ensuring that the control board 1-3 remains stable and does not move during the construction process.

[0045] When the present invention is used, the user first places a certain amount of mortar on the block, and the scraper 2-4 can evenly spread the mortar on the surface of the block through the sliding of the working frame 2-1. When the scraper 2-4 needs to spread the mortar on the vertical block, the user applies appropriate pressure to the pressure arm 2-7, and the pressure arm 2-7 drives the slide 2-3 to move upward along the column 2-2, thereby spreading the mortar on the vertical block; through the coordinated action of the pressure arm 2-7 and the slide 2-3, the construction workers can quickly and accurately complete the mortar spreading of the vertical blocks, which significantly improves the work efficiency.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
