Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

Embodiment one, combine the attached fig. 1, 2 and 3, a road and bridge cement mortar caulking device, include a cylinder 1 of the cement mortar caulking gun, characterized by, the said cylinder 1 is fitted with two outside fixedly and regards axis of the cylinder 1 as the symmetrical line, present the square boss 2 that sets up symmetrically, the said square boss 2 has two square through holes 3 that set up vertically side by side from side to side along the axial of the cylinder 1, the lower end opening of the said square through hole 3 is smaller than the upper end opening, and there is a vertical slide bar 4 set up in the hole, the said slide bar 4 bottom is square, the pole body is cylindrical, the top of the slide bar connects a rectangular block 5 at the same time, the side length of the said rectangular block 5 is greater than the diameter of the cylindrical pole body of the slide bar 4, the diameter of the cylindrical pole body is equal to the side length of the square bottom, meanwhile, the side length of the square bottom of the said slide bar 4 is equal to the side length of the opening of the square through hole 3 lower end on the square boss, the rectangular block 5 connected with the upper end is equal to the open side length of the upper end of the square through hole 3, so that the sliding rod 4 can slide in the square through hole 3, the lower bottom surface in the square through hole 3 is connected with the spring 6 sleeved outside the sliding rod 4, the spring 6 is arranged in the square through hole 3, the diameter of the spring is larger than the side length of the lower bottom surface of the square through hole 3 and is smaller than the side length of the rectangular block 5, so that the spring 6 can be compressed or released by the rectangular block 5 when the sliding rod 4 is in different working positions, the lower end of the sliding rod 4 is rotatably connected with the connecting rod 7, a round-head nozzle 17 and a flat-head nozzle 18 are respectively hinged between the two connecting rods 7 at the inner side and between the two groups of connecting rods 7 at the outer side, the nozzle required to be clamped at the bottom of the barrel body 1 according to requirements, the sliding rod 4 clamps the nozzle through a clamping device during operation, the top of the barrel body 1 is rotatably provided with a top cover 13 through thread fit, top cap 13 axial sliding connection push rod 14, push rod 14 stretch into the one end in the barrel 1 be connected with the gliding rubber piston 15 of barrel 1 inside wall cooperation, the other end is connected with handle 16, satisfy and slide in barrel 1 through pulling handle 16 and then drive piston 15, utilize the leakproofness of rubber piston 15 and barrel 1 lateral wall laminating, be convenient for utilize needle tubing principle to satisfy the device and absorb cement mortar into in the barrel 1.

Embodiment two, on the basis of embodiment one, combine figures 1 and 4, chucking device include a rotatory snap ring 8 of connecting outside barrel 1, snap ring 8 lower extreme connect an annular plate 9, annular plate 9 on open and to have the arc structure that is the symmetry and sets up, the arc structure include two sets of arc holes 10 that set up with one heart, arc hole 10 with one side uses with the cooperation between two sets of slide bars 4 of corresponding side respectively, satisfy promptly when assembling slide bar 4 in square through hole 3, the distance of its axis to barrel 1 axis equals with the distance of central line to barrel 1 axis in arc hole 10, arc hole 10 tip open and to have the snap ring 8 of a rotational connection, the annular plate 9 on open and to have the arc structure that is the symmetry and sets up, the arc structure include that two sets of arc holes 10 that set up with one heart, the arc hole 10 tip open and to have

The rectangular hole 10 changes from large to small along the arc direction from the opening diameter in the direction of the rectangular hole 11, so that after the rectangular block 5 enters the gap, the diameter of the arc hole 10 matched with the rectangular block 5 becomes small along with the rotation of the snap ring 8, the rectangular block 5 is bound by the arc hole 10, the rectangular block 5 cannot slide out of the gap, when the rectangular block 5 enters the gap, the spring 6 sleeved on the slide rod 4 is in a natural state, namely the length of the spring is smaller than the distance from the bottom surface of the square through hole 3 to the annular plate 9, but in order to provide sufficient spring force, its minimum length should also be greater than the length of the square boss 2.

In the third embodiment, on the basis of the second embodiment, with reference to fig. 1 and 4, when any nozzle is clamped and sleeved on the cylinder 1, the rectangular block 5 connected with the sliding rod 4 is positioned between the snap ring 8 and the annular plate 9, and simultaneously, the lower end face of the rectangular block 5 is in a tight state with the upper end face of the annular plate 9, at this time, the snap ring 8 is rotated, and the diameter of the opening at the matching position of the arc-shaped hole 10 and the sliding rod 4 is reduced along with the rotation of the snap ring 8, so that the rectangular block 5 cannot be separated from the annular plate 9 due to the stress of the nozzle, and the nozzle is separated from the cylinder 1, and the nozzle can be stored to the side face of the cylinder 1 when not in use, in a specific embodiment, when the inner wall of the nozzle is matched with the circular boss 12, the spring 6 is compressed by the rectangular block 5 of the sliding rod 4 and the lower end face of the square through hole 3, and the sliding rod 4 is far away from the square through hole 3 due to the elastic force of the spring 6, the trend that moves to the snap ring 8 department that is located square through hole 3 top, connecting rod 7 that links to each other with slide bar 4 should also produce the trend of doing the same motion with slide bar 4 this moment, but because the other end of connecting rod 7 at this moment links to each other with the nozzle, and the nozzle is located the relation of barrel 1 side, just make the one end that connecting rod 7 and nozzle link to each other drive the nozzle and produce the pivoted trend, but because the reason that the inner wall of nozzle was blockked by circular boss 12, just make circular boss 12 have the constraint effect to the nozzle, just realized hanging the function of placing on circular boss 12 with the nozzle, when will take off the nozzle, only need to separate the inner wall of nozzle and circular boss 12, just can easily take off.

When the spray nozzle clamping sleeve is used, a nozzle required to be used is taken down from the circular boss 12, the nozzle is pulled to be clamped and sleeved on the cylinder body 1, the position of the rectangular hole 11 in the clamping ring 8 is adjusted in a rotating mode while the sleeve is clamped, and therefore when the nozzle is clamped and sleeved on the cylinder body 1, the sliding rod 4 can pass through the rectangular hole 11

The nozzle penetrates through the annular plate 9, then the clamping ring 8 is rotated to clamp the nozzle, when the material is sucked, the nozzle is placed into the treated cement mortar, the push rod 14 is pulled, the material can be sucked into the barrel 1 by utilizing the needle tube principle, the push rod 14 is pushed to spray the material from the nozzle, if the nozzle needs to be replaced in the use process, the push rod 14 needs to be pushed into the barrel 1 completely to ensure that excessive material does not exist in the barrel 1, so that the phenomenon that the pressure in the barrel 1 is changed when the nozzle is taken down to cause the material to be sprayed out and waste is caused, after the material is emptied, the nozzle can be pulled to be separated from the barrel 1 only by rotating the clamping ring 8 to loosen the constraint on the sliding rod 4, because the nozzle is clamped on the barrel 1 and is clamped by a clamping device, the connecting part of the nozzle and the barrel 1 cannot have an overlarge gap caused by adopting spiral tightening, the problem that the nozzle is difficult to remove after cement mortar is solidified is improved to a great extent.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
