Description

Technical Field

[0001] The utility model relates to the technical field of furniture production, in particular to a furniture impact detection device. Background Technique

[0002] After furniture is produced, it needs to undergo impact detection before it can be sold on the market. By detecting the performance of furniture when it is impacted, its durability and impact resistance can be evaluated. This can help identify potential problems during the use of furniture and ensure that it can withstand the impacts and pressures during normal use.

[0003] Currently, when conducting impact detection on furniture, it is necessary to fix it first to prevent the furniture from shifting during the impact detection process, which may affect the reliability of the detection results. However, the existing detection devices can only fix furniture of specific sizes, with poor applicability. Moreover, when detecting a batch of furniture, it is necessary to place and fix the furniture first, remove it after detection, and then place and fix the next piece of furniture. This process consumes time and affects the continuity and efficiency of the detection. Content of the Utility Model

[0004] The purpose of the utility model is to provide a furniture impact detection device with strong applicability and high efficiency in batch detection.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A furniture impact detection device includes a bottom plate. On both sides of the upper surface of the bottom plate, two U-shaped plates are installed through adjusting mechanisms. Inside the U-shaped plates, there are clamping plates. On the surface of the U-shaped plates, first screws are installed, and the ends of the first screws are rotatably connected to the clamping plates. On both sides in the length direction of the clamping plates, limiting rods are connected. The ends of the limiting rods penetrate to the outside of the U-shaped plates. On the upper surface of the bottom plate, an L-shaped vertical plate is installed through a moving mechanism. The moving mechanism can drive the L-shaped vertical plate to move along the length direction of the bottom plate. On the upper surface of the horizontal plate at the top of the L-shaped vertical plate, a winch is installed. The end of the steel wire rope of the winch is connected to an electromagnet, and an impact head is arranged at the bottom of the electromagnet.

[0007] It can be seen that through the setting of the adjusting mechanism, the distance between the two U-shaped plates can be adjusted, so the purpose of fixing furniture of different sizes can be achieved, with strong applicability. Through the setting of two groups of adjusting mechanisms and two groups of U-shaped plates, the purpose of alternating use can be realized. When the furniture is fixed on one group of U-shaped plates for detection, the staff can disassemble and fix the furniture on the other group of U-shaped plates. After the previous furniture is detected, only need to drive the L-shaped vertical plate to move above the current furniture through the moving mechanism to continue the detection, thus ensuring that the continuity of the detection is not interrupted and improving the efficiency.

[0008] Further, the adjusting mechanism includes a first installation groove formed on the upper surface of the base plate. A second screw rod with a pair of reverse threads is rotatably connected inside the first installation groove. Nut seats are installed on the two reverse threads of the second screw rod, and the end of the nut seat is connected to the bottom of the U-shaped plate.

[0009] When the second screw rod is rotated, due to the arrangement of the reverse threads on its surface, the two nut seats can be driven to move inward or outward simultaneously, achieving the purpose of adjusting the distance between the two U-shaped plates.

[0010] Further, the moving mechanism includes a second installation groove formed on the upper surface of the base plate. A third screw rod is rotatably connected inside the second installation groove, and the L-shaped vertical plate is installed on the third screw rod. A motor is installed on the side surface of the base plate, and the output shaft of the motor is connected to the third screw rod.

[0011] When the motor is started, it drives the third screw rod to rotate, which can drive the L-shaped vertical plate to move along its length direction, achieving the purpose of alternating the use of the two groups of U-shaped plates, ensuring the continuity of detection is not interrupted, and improving efficiency.

[0012] Further, first sliding grooves are formed on both sides of the first installation groove on the upper surface of the base plate. First sliding blocks are arranged inside the first sliding grooves, and the end of the first sliding block is connected to the lower surface of the U-shaped plate.

[0013] Through the arrangement of the first sliding groove and the first sliding block, the limiting effect on the U-shaped plate can be improved, not only improving its smoothness during movement, but also enhancing its structural strength and reducing the impact on the U-shaped plate during the impact detection process.

[0014] Further, a second sliding groove is formed on the outer surface of the vertical plate of the L-shaped vertical plate. A second sliding block is arranged inside the second sliding groove. A connecting rod is connected to the outer surface of the impact head, and the connecting rod is connected to the second sliding block through a bolt.

[0015] Through the arrangement of the second sliding groove, the second sliding block and the connecting rod, a limiting effect can be provided for the impact head, enabling the impact head to perform impact detection on the specified position of the furniture, avoiding deviation. And since the second sliding block and the connecting rod are connected through a bolt, it is convenient to replace the impact head to meet the side view effects of different impact forces.

[0016] Further, rubber pads are arranged on the inner wall of the U-shaped plate and the outer surface of the clamping plate, and anti-slip patterns are formed on the outer surface of the rubber pads.

[0017] Through the arrangement of the rubber pads, the protection effect on the furniture can be improved, avoiding damage to the surface of the furniture. And in combination with the arrangement of the anti-slip patterns, the friction with the furniture can be further increased, improving the fixing effect. Description of the Drawings

Specific embodiments

[0023] The present utility model will be described in detail below with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, a furniture impact detection device includes a base plate 100. Two U-shaped plates 101 are installed on both sides of the upper surface of the base plate 100 through an adjustment mechanism 200. A clamping plate 102 is arranged inside the U-shaped plate 101. A first screw 103 is installed on the surface of the U-shaped plate 101, and the end of the first screw 103 is rotatably connected to the clamping plate 102. Limit rods 108 are connected to both sides in the length direction of the clamping plate 102, and the ends of the limit rods 108 penetrate to the outside of the U-shaped plate 101. An L-shaped vertical plate 104 is installed on the upper surface of the base plate 100 through a moving mechanism 300. The moving mechanism 300 can drive the L-shaped vertical plate 104 to move along the length direction of the base plate 100. A winch 105 is installed on the upper surface of the horizontal plate at the top of the L-shaped vertical plate 104. The end of the steel wire rope of the winch 105 is connected to an electromagnet 106, and an impact head 107 is arranged at the bottom of the electromagnet 106.

[0025] During use, first adjust the distance between the two U-shaped plates 101 through the adjusting mechanism 200. Then, place the feet of furniture such as a chair inside the two U-shaped plates 101. Rotate the first screw 103. Since the clamping plate 102 is limited by the limiting rod 108, it can drive the clamping plate 102 to press tightly against the outer surface of the foot to achieve the purpose of fixation. Then, drive the impact head 107 to rise by the winch 105. Subsequently, cut off the power supply of the electromagnet 106 to release the impact head 107, so that the impact head 107 falls on the furniture for impact detection. And through the setting of two groups of adjusting mechanisms 200 and two groups of U-shaped plates 101, the purpose of alternating use can be achieved. When the furniture is fixed on one group of U-shaped plates 101 for detection, the staff can disassemble and fix the furniture on the other group of U-shaped plates 101. When the previous furniture is completed with detection, only need to drive the L-shaped vertical plate 104 to move above the current furniture through the moving mechanism 300 to continue the detection, thus ensuring that the continuity of the detection is not interrupted and improving the efficiency. It should be noted that the material of the impact head 107 is iron, which can be magnetically adsorbed by the electromagnet 106.

[0026] Specifically, the adjusting mechanism 200 includes a first installation groove 201 opened on the upper surface of the bottom plate 100. A second screw 202 with a pair of reverse threads is rotatably connected inside the first installation groove 201. Nut seats 203 are installed on the two reverse threads of the second screw 202, and the end of the nut seat 203 is connected to the bottom of the U-shaped plate 101. When the second screw 202 is rotated, due to the setting of the reverse threads on its surface, the two nut seats 203 can be driven to move inward or outward simultaneously to achieve the purpose of adjusting the distance between the two U-shaped plates 101.

[0027] Specifically, the moving mechanism 300 includes a second installation groove 301 opened on the upper surface of the bottom plate 100. A third screw 302 is rotatably connected inside the second installation groove 301, and the L-shaped vertical plate 104 is installed on the third screw 302. A motor 303 is installed on the side surface of the bottom plate 100, and the output shaft of the motor 303 is connected to the third screw 302. When the motor 303 is started, it drives the third screw 302 to rotate, which can drive the L-shaped vertical plate 104 to move along its length direction to achieve the purpose of alternating use of the two groups of U-shaped plates 101, ensuring that the continuity of the detection is not interrupted and improving the efficiency.

[0028] Specifically, first chutes 400 are opened on both sides of the first installation groove 201 on the upper surface of the bottom plate 100. First sliders 401 are arranged inside the first chutes 400, and the end of the first slider 401 is connected to the lower surface of the U-shaped plate 101. Through the setting of the first chutes 400 and the first sliders 401, the limiting effect on the U-shaped plate 101 can be improved, not only improving its smoothness during movement, but also improving its structural strength and reducing the influence on the U-shaped plate 101 during the impact detection process.

[0029] Specifically, a second sliding groove 500 is formed on the outer surface of the vertical plate of the L-shaped vertical plate 104. A second sliding block 501 is arranged inside the second sliding groove 500. A connecting rod 502 is connected to the outer surface of the impact head 107. The connecting rod 502 and the second sliding block 501 are connected by bolts. Through the arrangement of the second sliding groove 500, the second sliding block 501 and the connecting rod 502, a limiting effect can be provided for the impact head 107, enabling the impact head 107 to perform impact detection on a specified position of the furniture, avoiding deviation. And because the second sliding block 501 and the connecting rod 502 are connected by bolts, it is convenient to replace the impact head 107 to meet the side view effects of different impact forces.

[0030] Specifically, rubber pads are arranged on the inner wall of the U-shaped plate 101 and the outer surface of the clamping plate 102. Anti-slip lines are formed on the outer surface of the rubber pads. Through the arrangement of the rubber pads, the protection effect on the furniture can be improved, avoiding damage to the surface of the furniture. And in cooperation with the arrangement of the anti-slip lines, the friction with the furniture can be further increased, improving the fixing effect.
