It also mostly refers to metal plates forged, rolled or cast. Decorative plates are often used in house decoration. During the production process, it is necessary to detect the strength of the decoration plates, so a device for detecting the strength of plates is required.

[0003] In the Chinese patent document with the publication number CN218470438U, a device for detecting the strength of raw materials of building engineering plates is disclosed, including a detection table. A load-bearing box is fixedly connected to the top of the detection table. Bearings are installed at both ends of the inner wall of the load-bearing box. Rotating rods are arranged inside both bearings. Adjusting plates are fixedly connected to the ends of both rotating rods. A movable rod is rotatably connected between the two adjusting plates. The other end of the movable rod is hinged to a connecting seat. A telescopic rod is fixedly connected to the bottom end of the connecting seat. A pressing head is fixedly connected to the bottom end of the telescopic rod. A measuring scale is arranged on the inner wall of the detection table. A scale disk is fixedly connected to the outer wall of the load-bearing box. Through the arrangement of the limiting plate, the limiting rod and the limiting spring, it is convenient to drive the clamping plate to adaptively fix the building plate. Through the arrangement of the limiting spring, it is convenient to adaptively fix and clamp according to the size of the building plate.

[0004] The deficiency of the above disclosed solution is that during use, it is necessary to first move the clamping plates on both sides to fix the plate, and then move the pressing head downward to press the plate. Therefore, the plate cannot be clamped and fixed while the pressing head moves downward, resulting in cumbersome operation steps, low automation degree, and reduced work efficiency. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a device for detecting the strength of building decoration plates. When the pressing head presses the plate, the plate can be fixed at the same time, and the automation degree is high, which can effectively solve the problems in the background technique.

[0010] Further, sliding rods are symmetrically and slidably arranged on the mounting plate, a pressing plate is fixedly arranged at the bottom of the sliding rod, and a second spring is fixedly arranged between the pressing plate and the mounting plate.

[0011] Further, a protective frame is fixedly arranged at the top of the pressing plate, and the protective frame allows the mounting plate to slide therein.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Since a second rack is fixedly arranged at the bottom of each of the two moving plates, the second rack meshes with the second gear, a first rack is fixedly arranged at the bottom of the mounting plate, and the first rack is in contact with and meshes with the first gear when they meet.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1, please refer to Figures 1 - 3 , this embodiment provides a technical solution: a building decoration board strength detection device, including a test bench 1. One side of the top of the test bench 1 is fixedly provided with an L-shaped fixing plate 14. A driving member is fixedly provided on the L-shaped fixing plate 14, and the output end of the driving member is fixedly provided with a mounting plate 3. The driving member is an electric telescopic rod 2. The electric telescopic rod 2 is fixedly installed at the bottom of the horizontal part of the L-shaped fixing plate 14, and the output rod of the electric telescopic rod 2 is fixedly connected to the mounting plate 3. The bottom of the mounting plate 3 is fixedly provided with a pressing head 4 through a connecting rod. The pressing head 4 is a frustum structure. The pressure on the test piece is increased.

[0022] A sliding groove 15 is formed in the top of the detection table 1 along its length direction, and two symmetrically arranged moving plates 10 are slidably arranged in the sliding groove 15. Two sliding shafts 11 are slidably arranged on the top of the moving plate 10, and sliding holes are symmetrically formed in the moving plate 10. The two sliding shafts 11 are respectively horizontally slidably arranged in the corresponding sliding holes. Blocks are fixedly arranged at one ends of the two sliding shafts 11 close to the detection table 1 to prevent the sliding shafts 11 from separating from the corresponding moving plates 10. The same clamping plate 13 is fixedly arranged at one ends of the two sliding shafts 11 away from the blocks. Two first springs 12 are fixedly arranged between the clamping plate 13 and the moving plate 10, and the two first springs 12 are respectively sleeved on the corresponding sliding shafts 11. When the first springs 12 are in the natural state, the blocks are in contact with the moving plates 10.

[0023] A receiving cavity is formed in the detection table 1, and the receiving cavity is communicated with the sliding groove 15. A transmission shaft 7 is horizontally rotatably arranged in the receiving cavity, and a first gear 6 and a second gear 8 are fixedly sleeved on the transmission shaft 7. Rack bars two 9 are fixedly arranged at the bottoms of the two moving plates 10, and the rack bars two 9 are meshed with the second gear 8. A rack bar one 5 is fixedly arranged at the bottom of the mounting plate 3, and an avoidance hole for avoiding the rack bar one 5 is formed in the detection table 1. The avoidance hole is communicated with the receiving cavity, and the rack bar one 5 is in contact and meshed with the first gear 6.

[0024] A measuring scale (not shown in the figure) is fixedly arranged on the top of the detection table 1, and the measuring scale is vertically arranged.

[0025] The working principle of the building decoration board strength detection device provided in this embodiment is as follows:

[0026] Place the board to be detected on the detection table 1 and between the two clamping plates 13. Start the electric telescopic rod 2. The electric telescopic rod 2 extends to drive the mounting plate 3 to move downward. The mounting plate 3 drives the rack bar one 5 and the pressing head 4 to move downward. When the rack bar one 5 passes through the avoidance hole on the detection table 1 and meshes with the first gear 6, the pressing head 4 has not yet contacted the board to be detected. Continue to move the rack bar one 5 and the pressing head 4 downward. The rack bar one 5 drives the first gear 6 to rotate. The first gear 6 drives the transmission shaft 7 to rotate. The transmission shaft 7 drives the second gear 8 to rotate. The second gear 8 drives the two rack bars two 9 to move towards each other. The two rack bars two 9 drive the two moving plates 10 to move towards each other along the sliding groove 15. The two moving plates 10 drive the corresponding clamping plates 13 to move through the sliding shafts 11 respectively.

[0027] When the clamping plate 13 contacts the board to be detected, continue to move the pressing head 4 downward, so that the two moving plates 10 continue to move towards each other. Under the reaction force of the board to be detected on the clamping plate 13, the clamping plate 13 pushes the sliding shaft 11 to horizontally slide on the moving plate 10, and at the same time compresses the first spring 12. The first spring 12 clamps the board to be detected by the clamping plate 13.

[0028] When the indenter 4 touches the plate, the electric telescopic rod 2 is closed. The elongation of the electric telescopic rod 2 is adjusted according to the thickness of the plate to be detected measured by the measuring ruler. Then, the electric telescopic rod 2 reaches the elongation and drives the indenter 4 to press the plate. The hardness value index is determined by the plastic deformation depth of the indentation on the plate. By performing a local anti-hard object test on the decorative plate to be detected, the hardness is detected to judge the strength of the decorative plate.

[0029] After the detection is completed, the electric telescopic rod 2 contracts. The electric telescopic rod 2 drives the indenter 4 and the first rack 5 to move upward. The first rack 5 drives the second gear 8 to rotate, causing the two second racks 9 to move away from each other. The two second racks 9 drive the two moving plates 10 to move away from each other, thereby driving the two clamping plates 13 to release the clamping of the plate.

[0030] Embodiment 2, please refer to Figures 4 - 5 , the difference between the technical solution of this embodiment and that of Embodiment 1 is that: sliding rods 16 are symmetrically and slidably arranged on the mounting plate 3. Through holes are symmetrically formed in the mounting plate 3. The sliding rod 16 includes a vertical rod, and the vertical rod is vertically slidably arranged in the corresponding through hole. The top end of the vertical rod passes upward through the through hole and is fixedly installed with a connecting block to prevent the sliding rod 16 from detaching from the mounting plate 3. A pressing plate 19 is fixedly arranged at the bottom of the vertical rod of the sliding rod 16. A second spring 17 is fixedly arranged between the pressing plate 19 and the mounting plate 3, and the second spring 17 is sleeved on the vertical rod of the corresponding sliding rod 16. When the second spring 17 is in a natural state, the connecting block of the sliding rod 16 is in contact with the top surface of the mounting plate 3.

[0031] A protective frame 18 is fixedly arranged on the top of the pressing plate 19, and the protective frame 18 allows the mounting plate 3 to slide therein. The protective frame 18 prevents the impurities from splashing when the indenter 4 detects the plate.

[0032] The difference in the working principle between this embodiment and Embodiment 1 is that:

[0033] When the electric telescopic rod 2 elongates, it drives the mounting plate 3 to move downward. The mounting plate 3 can slide along the inside of the protective frame 18. The mounting plate 3 drives the pressing plate 19 and the indenter 4 to move downward. The pressing plate 19 first touches the plate to be detected. When the indenter 4 continues to move downward, under the reaction force of the plate to be detected on the pressing plate 19, the pressing plate 19 pushes the sliding rod 16 to slide on the mounting plate 3 upward and simultaneously compresses the second spring 17. The restoring force of the second spring 17 causes the pressing plate 19 to press the plate to be detected tightly to prevent the plate from moving.

[0034] When the indenter 4 contacts the sheet material, the electric telescopic rod 2 is closed. The elongation of the electric telescopic rod 2 is adjusted according to the thickness of the sheet material to be detected measured by the measuring scale. Then, the electric telescopic rod 2 reaches the elongation and drives the indenter 4 to press the sheet material. The hardness value index is determined by the plastic deformation depth of the indentation on the sheet material. The hardness detection is carried out by performing a local anti-hard object test on the decoration sheet material to be detected, so as to judge the strength of the decoration sheet material.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
