Especially in highway engineering and urban road engineering, they have become indispensable building decoration materials. Brick products mainly include brick floor tiles, brick interlocking bricks and brick colored blocks, etc. Paving the ground with brick interlocking bricks can not only make the ground form various beautiful patterns, but also has the advantages of good anti-slip performance, high load resistance, strong practicability, convenient paving and low price. It is a new paving and road product that has developed rapidly in the world in the past two decades and is very popular among designers and constructors.

[0003] In a brick-paved road surface, since the gap between adjacent bricks is very small, when it is necessary to take out the bricks from the brick-paved road surface, a brick clamp needs to be used. However, the existing brick clamps not only have insufficient clamping force on the bricks, but also have a single brick model that can be clamped, so that the existing brick clamps cannot be widely used for clamping bricks of different models and need to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a portable road brick clamp with good clamping force on bricks and can be widely used for clamping bricks of different models.

[0005] The utility model provides a portable road brick clamp, which includes a main rod, a pair of first connecting pieces, a pair of holding rods, a pair of second connecting pieces and a pair of clamping plates. The two first connecting pieces are fixedly arranged at the bottoms of both ends of the main rod. One end of the holding rod is provided with a hinged handle, and the first connecting piece is hinged to the upper end of the hinged handle; the clamping plate is fixedly arranged at the bottom end of the second connecting piece, and the second connecting piece is hinged to the lower end of the hinged handle. The two holding rods rotate towards the main rod to drive the two clamping plates to move towards each other; the main rod includes a first rod body and a second rod body. Both ends of the first rod body and the second rod body facing each other are provided with screw holes. A screw rod is arranged between the first rod body and the second rod body. A screwing member is fixedly arranged on the screw rod. The screw threads of the screw rod on both sides of the screwing member are in opposite directions. Both ends of the screw rod are respectively threadedly connected to the screw holes of the first rod body and the second rod body.

[0006] Preferably, a first hinge hole is formed on the surface of the hinged handle, a third hinge hole is formed on the surface of the first connecting piece, and a first pin shaft is inserted into the first hinge hole and the third hinge hole.

[0007] Preferably, the first connecting member is composed of two connecting plates, the two connecting plates are respectively fixedly connected to both sides of one end of the main rod, the two connecting plates are perpendicular to the main rod, the third hinge hole is formed on the surface of the connecting plate, and the hinge handle is clamped between the two connecting plates and hinged to the two connecting plates.

[0008] Preferably, a second hinge hole is formed on the surface of the hinge handle, the second hinge hole is located at the bottom end of the first hinge hole, a fourth hinge hole is formed on the surface of the second connecting member, and a second pin shaft is inserted through the second hinge hole and the fourth hinge hole.

[0009] Preferably, the length dimension of the screw rod is set to "L" and satisfies 120mm < L < 160mm; the length dimension of the screwing member is set to "N" and satisfies N = 20mm.

[0010] Preferably, the length dimension of the grip rod is set to "D", the spacing dimension between the main rod and the hinge handle is set to "W", and satisfies 5W < D < 7W.

[0014] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:

[0015] 1. According to the length dimension of the brick to be clamped, hold the screwing member and rotate the screw rod to adjust the length dimensions of the two ends of the screw rod respectively screwed into the screw holes, so as to adjust the spacing between the two clamping plates, so that the spacing between the two clamping plates matches the length dimension of the brick, so as to be able to adapt to the clamping of bricks of different model sizes and have good clamping force on the bricks.

[0016] 2. A limiting plate is horizontally arranged at the top end of the clamping plate. The setting of the limiting plate prevents the top end of the brick from exceeding the top end of the clamping plate, so that the clamping plate and the side surface of the brick have the largest contact area during clamping; and a plurality of tooth marks are formed on the opposite surfaces of the two clamping plates.

Detailed Description of the Embodiment

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the following further details the present utility model with reference to the Figures 1-9 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] Referring to Figure 1 、 Figure 2 and Figure 3 ,a portable road brick clamp, comprising a main rod 1, a pair of first connecting members 2, a pair of holding rods 3, a pair of second connecting members 4 and a pair of clamping plates 5. The first connecting member 2 consists of two connecting plates 21 which are vertically fixed on both sides of one end of the main rod 1, and a third hinge hole 22 is formed by opening on the surface of the connecting plate 21. An articulated handle 31 is formed at one end of the holding rod 3, and a first hinge hole 311 and a second hinge hole 312 are formed by opening on the surface of the articulated handle 31, wherein the first hinge hole 311 is located above the second hinge hole 312. The articulated handle 31 is placed between the two connecting plates 21, and the first hinge hole 311 on the surface of the articulated handle 31 corresponds to the third hinge hole 22 on the surface of the connecting plate 21. A first pin shaft 32 is inserted through the first hinge hole 311 and the third hinge hole 22, thereby realizing the hinge between the holding rod 3 and the main rod 1.

[0030] Referring to Figure 4 、 Figure 5 and Figure 6 ,the clamping plate 5 is vertically and fixedly arranged below the second connecting member 4, and a fourth hinge hole 41 is formed by opening on the surface of the second connecting member 4. The fourth hinge hole 41 on the surface of the second connecting member 4 corresponds to the second hinge hole 312 on the surface of the articulated handle 31, and a second pin shaft 42 is inserted through the second hinge hole 312 and the fourth hinge hole 41, thereby also realizing the hinge between the clamping plate 5 and the holding rod 3. In the normal state, the clamping plate 5 is in a vertical state and the holding rod 3 is in a horizontal state. When it is necessary to use this brick clamp to pick up a brick, the two clamping plates 5 are placed on both sides of the brick, and both hands hold the two holding rods 3 in the direction close to the main rod 1, so that the articulated plate rotates in the direction close to the main rod 1 along the first pin shaft 32, thereby driving the two clamping plates 5 to move in the direction close to each other until the two clamping plates 5 respectively abut against both sides of the brick, thereby completing the clamping of the brick by this brick clamp.

[0031] Referring to Figure 7 ,when clamping, the holding rod 3 is held in the direction of the main rod 1. In order to avoid interference between the end of the holding rod 3 and the main rod 1 due to the too long holding rod 3, which affects the clamping distance between the two clamping plates 5. The length dimension of the holding rod 3 is set to "D", and the distance dimension between the main rod 1 and the articulated handle 31 is set to "W", and it is ensured that the distance dimension W between the main rod 1 and the articulated handle 31 and the length dimension D of the holding rod 3 satisfy 5W < D < 7W, thereby setting the holding rod 3 to a suitable length dimension, that is, avoiding interference between the holding rod 3 and the main rod 1 due to the too long holding rod 3, and also avoiding the laborious clamping due to the too short holding rod 3.

[0032] Referring to Figure 4 andFigure 8 When it is necessary to clamp bricks from the ground, in order to enable the bottom end of the clamping plate 5 to be smoothly clamped into the gap of the bricks, a pointed plate 6 is extended and provided at the bottom end of the clamping plate 5. The thickness dimension of the provided pointed plate 6 gradually decreases from the top end of the pointed plate 6 to the bottom end of the pointed plate 6. Additionally, a limiting plate 7 is horizontally and fixedly provided at the top end of the clamping plate 5. When the brick clamp clamps the bricks, the top end of the bricks abuts against the bottom surface of the limiting plate 7. Through the setting of the limiting plate 7, a limiting effect is exerted on the bricks, preventing the top end of the bricks from exceeding the top of the clamping plate 5 during the clamping process. In order to enable the two clamping plates 5 to clamp the bricks more firmly, a number of tooth marks 51 are formed on the opposite surfaces of the two clamping plates 5. During clamping, the two clamping plates 5 respectively abut against the two side surfaces of the bricks. The opening of the tooth marks 51 on the surface of the clamping plate 5 increases the frictional force between the clamping plate 5 and the surface of the bricks, thereby enabling the brick clamp to clamp the bricks more firmly during the clamping process.

[0033] Refer to Figure 7 and Figure 9 In order to enable the brick clamp to clamp bricks of different sizes, the main rod 1 is set to include a first rod body 11 and a second rod body 12. Thread holes 111 are formed on the opposite surfaces of the first rod body 11 and the second rod body 12. A screw rod 14 is provided between the first rod body 11 and the second rod body 12. A turning member 13 is formed at the middle position of the screw rod 14. The thread directions of the screw rod 14 on both sides of the turning member 13 are opposite. The two ends of the screw rod 14 are respectively threadedly connected to the thread holes 111 of the first rod body 11 and the second rod body 12. The length dimension of the screw rod 14 is set to "L", and the length dimension of the screw rod 14 satisfies 120mm < L < 160mm; the length dimension of the turning member is set to "N", and N = 20mm.

[0034] According to the length dimension of the bricks to be clamped, hold the turning member 13 and rotate the screw rod 14. When the length dimension of the bricks to be clamped is relatively small, rotate the screw rod 14 forward. The two ends of the screw rod 14 are gradually screwed into the thread holes 111 of the first rod body 11 and the second rod body 12, causing the two clamping plates 5 to move towards each other, and the distance between the two clamping plates 5 gradually decreases to adapt to the length dimension of the bricks. When the length dimension of the bricks to be clamped is relatively large, rotate the screw rod 14 in reverse. The two ends of the screw rod 14 are gradually screwed out of the thread holes 111 of the first rod body 11 and the second rod body 12, causing the two clamping plates 5 to move away from each other, and the distance between the two clamping plates 5 gradually increases to adapt to the length dimension of the bricks. Thus, the brick clamp can adapt to the clamping of bricks of different sizes.

[0035] The specific implementation principle of the embodiment of the present application is as follows: when it is necessary to take out the bricks of the brick paving road, according to the length of the brick to be taken out, the screw rod 14 is rotated by holding the twisting member 13, thereby changing the length of the two ends of the screw rod 14 threaded into the screw hole 111, so as to adjust the spacing between the two clamping plates 5 to adapt to the length of the brick. The pointed plates 6 at the bottom ends of the two clamping plates 5 are inserted into the gap between the bricks until the limiting plate 7 at the top of the clamping plate 5 abuts against the upper surface of the brick. The limiting plate 7 is set to prevent the top of the brick from exceeding the top of the clamping plate 5 when clamping, so that the brick clamp can have the maximum contact area between the clamping plate 5 and the brick when clamping.

[0036] Then, hold the two gripping rods 3 and the main rod 1 with both hands, and hold the two gripping rods 3 in the direction close to the main rod 1, so that the two gripping rods 3 rotate in the direction close to the main rod 1, and the rotation of the gripping rods 3 drives the hinge handle 31 to rotate along the first pin 32. Thus, the two clamping plates 5 move in the direction close to each other until the two clamping plates 5 are tightly pressed against the two side surfaces of the brick, so that the brick clamp can be lifted to remove the brick from the brick paving road surface. The plurality of tooth marks 51 on the surface of the clamping plate 5 increase the friction between the clamping plate 5 and the surface of the brick, so that the two clamping plates 5 clamp the brick more firmly.

[0037] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all protected by the utility model.
