It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1-3 As shown, the positioning device for stone bonding proposed in this utility model includes a placement frame 1, which is L-shaped; The upper and lower ends of the placement rack 1 are fixedly connected with two vertical rods 2, which are symmetrically distributed. An adjustment plate 4 is slidably connected to each pair of vertical rods 2. The middle of the upper and lower ends of the placement rack 1 is rotatably connected with a first screw 3 that passes through the adjustment plate 4. A rotating plate 5 is hinged to the side of each adjustment plate 4 away from the first screw 3. Two sets of spring telescopic rods 6 are installed on the side of each rotating plate 5 close to the placement rack 1. A guide wheel 7 is installed on the end of each spring telescopic rod 6 away from the rotating plate 5. Each adjusting plate 4 and rotating plate 5 is equipped with a latch 12 on both the left and right sides for locking the rotating plate 5. The latch 12 locks and fixes the rotating plate 5 when it is rotated to be parallel to the adjusting plate 4. Each adjusting plate 4 is fixedly connected to the side near the placement frame 1 with two sets of second pressure rods 13, which are symmetrically distributed. There are two second pressure rods 13 in each set, and each set of second pressure rods 13 is symmetrically distributed on the left and right sides.

[0020] In this utility model, since the two adjusting plates 4 are located at the upper and lower ends of the placement frame 1, that is, they are symmetrically distributed at ninety degrees, the rotating first screw 3 drives the adjusting plate 4 to move towards the side closer to the placement frame 1. When the second pressure rod 13 on the adjusting plate 4 presses against the two vertically placed stones, a vertical force can be applied to the two vertical stones, so that the right-angle bonding joint of the stones can be tightly fitted. The spring telescopic rod 6 and guide wheel 7 on the adjusting plate 4 can provide elastic support for stones placed in parallel or perpendicular pairs. This allows the upper surface of parallel bonded stones to be more flush under the elastic support and contact of the upper spring telescopic rod 6 and guide wheel 7, improving the positioning and bonding effect. When the upper and lower spring telescopic rods 6 and guide wheels 7 support and contact right-angle bonded stones, they can provide initial support and positioning for the stones. In the subsequent positioning and locking process, there is no need to manually support the stones.

[0021] It should be noted that there are two spring telescopic rods 6 in each group, and each group of spring telescopic rods 6 is symmetrically distributed on the rotating plate 5. The spring telescopic rods 6 on the two rotating plates 5 are staggered left and right. The spring telescopic rod 6 consists of a sleeve rod, a sliding rod, and a spring. The sliding rod is fixedly connected to the rotating plate 5, while the sleeve rod is slidably connected to the sliding rod. The spring is fixedly connected between the sleeve rod and the rotating plate 5, so that the spring telescopic rod 6 can retract when it is subjected to resistance. The guide wheel 7 is installed on the end of the sleeve rod near the placement frame 1. After the guide wheel 7 at the end of the spring telescopic rod 6 comes into contact with the placed stone, it can apply a certain supporting force to the stone, so that the stone fits the placement frame 1 more closely, and thus provide initial support and positioning for the stone.

[0022] The adjusting plate 4 has a first threaded hole in the middle, and the first threaded hole is adapted to the thread on the outside of the first screw 3, so that the rotating first screw 3 can drive the adjusting plate 4 to move towards or away from the placement frame 1.

[0023] In an optional embodiment, two crossbars 8 are fixedly connected to both the front and rear sides of the placement frame 1, and an adjustment frame 9 is slidably connected to each pair of crossbars 8. A second screw 10 passing through the adjustment frame 9 is rotatably connected to the right angle of the placement frame 1. The adjustment frame 9 is L-shaped, and two sets of first pressure rods 11 are fixedly connected to the side of the adjustment frame 9 closest to the placement frame 1, and are distributed symmetrically at right angles.

[0024] In this embodiment, by rotating the second screws 10 on the left and right sides, the first pressure rod 11 on the adjusting frame 9 is driven to abut against the left and right sides of the parallel or perpendicular bonded stone to complete the locking and positioning of the bonded stone.

[0025] It should be noted that a second threaded hole is provided at the right angle of the adjusting frame 9, and the second threaded hole is adapted to the thread on the outside of the second screw 10, so that the rotating second screw 10 can drive the adjusting frame 9 to move towards or away from the placement frame 1 for adjustment. The threads on the outside of the first screw 3 and the second screw 10 are both triangular threads, so as to improve the stability of the first screw 3 and the second screw 10 in supporting the adjusting plate 4 and the adjusting frame 9 when they are not rotating.

[0026] The first pressure rod 11 and the second pressure rod 13 are both T-shaped at the end near the placement frame 1, and the T-shaped ends of the first pressure rod 11 and the second pressure rod 13 are both in contact with the inner side of the placement frame 1, so that the first pressure rod 11 and the second pressure rod 13 in contact with the inner side of the placement frame 1 can move stably within the placement frame 1, so that the stone that needs to be positioned after bonding can be stably resisted and squeezed.

[0027] In addition, the end of the vertical rod 2 that passes through the adjusting plate 4 and the end of the horizontal rod 8 that passes through the adjusting frame 9 are both T-shaped. The adjusting plate 4 and the adjusting frame 9 are provided with round holes for the vertical rod 2 and the horizontal rod 8 to slide. Through the round holes for the vertical rod 2 and the horizontal rod 8 to slide, the adjusting plate 4 and the adjusting frame 9 can slide stably on the vertical rod 2 and the horizontal rod 8 respectively, and are blocked by the T-shaped ends of the vertical rod 2 and the horizontal rod 8, so as not to separate from the vertical rod 2 and the horizontal rod 8.

[0028] The working principle in the above embodiments is as follows: Since the two adjusting plates 4 are located at the upper and lower ends of the placement frame 1, that is, they are symmetrically distributed at ninety degrees, when supporting and positioning the parallel bonded stones, the buckles 12 on the lower adjusting plate 4 and the rotating plate 5 can be opened, and then the lower rotating plate 5 can be rotated 180 degrees. Without using the spring telescopic rod 6 and guide wheel 7 on the lower adjusting plate 4, the two parallel bonded stones are placed horizontally inside the placement frame 1, with a certain gap left at the bonding point, and can be resisted by the spring telescopic rod 6 and guide wheel 7 on the upper adjusting plate 4. The first screw 3 at the bottom can be rotated to adjust the adjustment plate 4 at the bottom, which will drive the second pressure rod 13 at the bottom to press against the stone and fit tightly against the inner right angle of the placement frame 1. Then, after applying adhesive to the stone bonding area, the second screw 10 on the left and right sides can be rotated to drive the first pressure rod 11 on the adjustment frame 9 to press against the left and right sides of the stone to complete the locking and positioning of the parallel bonded stone. When vertically bonding stones require support and positioning, the flip plate on the upper adjustment plate 4 needs to be flipped over. The upper spring telescopic rod 6 and guide wheel 7 are not needed. First, place the horizontal stone into the placement frame 1. Then, fix the horizontally placed stone with the second pressure rod 13 on the lower adjustment plate 4. Apply adhesive to the bonding area, then place the vertical stone against the bonding area. Supported by the spring telescopic rod 6 and guide wheel 7 on the lower adjustment plate 4, rotate the second screws 10 on both sides to move the first pressure rod 11 on the adjustment frame 9 to contact the left and right sides of the stone. Finally, rotate the upper first screw 3 to move the adjustment plate 4 towards the side closer to the placement frame 1. When the second pressure rod 13 on the adjustment plate 4 presses against the two vertically placed stones, a vertical force is applied to the two vertical stones, ensuring a tight fit at the right-angle bonding point, thus completing the positioning and locking of the right-angle bonding.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
