Description

Technical Field

[0001] The invention relates to the technical field of baby crib frames, and in particular to a frame strength testing device for baby crib processing. Background Art

[0002] The frame of a crib is an important part of the crib. It supports the structure of the entire bed and ensures the stability and safety of the crib. The frame of a crib is made of a variety of materials, including solid wood, metal (such as iron, aluminum, etc.) and plastic. Among them, solid wood frames are popular for their natural environmental protection, strong and durable texture; metal frames are light and easy to clean; plastic frames are relatively cheap, but may not be as strong as solid wood and metal frames.

[0003] For the current testing devices, the existing baby crib processing skeleton strength testing device disclosed by patent number "CN215262820U" can fix the baby crib skeletons of different sizes by placing the baby crib skeleton between two buffer plates and using the controller to make the electric telescopic rod drive the support plate and the slider to move, and the baby crib skeletons of different sizes can be squeezed by the sliding slide. However, when this device needs to test multiple baby crib skeletons, the staff needs to frequently install the baby crib skeletons on the two buffer plates. After the test is completed, they need to be disassembled one by one in order to replace the next test product. This repetitive installation and disassembly process not only greatly slows down the test speed and reduces the overall work efficiency, but also significantly increases the operating burden and labor intensity of the staff. Accordingly, the present application proposes a utility model content, a baby crib processing skeleton strength testing device. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a frame strength testing device for baby crib processing.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Embodiment 1:

[0031] Reference Figure 1 , Figure 2 and Figure 3 A frame strength testing device for baby crib processing includes a workbench 1, a support frame 2 fixedly connected to the top surface of the workbench 1, and a support block 11 symmetrically fixedly connected to the top surface of the workbench 1. The top surface of the workbench 1 is symmetrically provided with a slide groove 101. The inner wall of the slide groove 101 is slidably connected with a connecting frame 6. The bottom surface of the connecting frame 6 is equipped with a protrusion that fits with the slide groove 101. Two groups of connecting rods 7 are fixedly connected to the inner surface of the connecting frame 6. The connecting rods 7 are respectively arranged around the inner wall of the connecting frame 6 to support the baby crib frame, so that the middle of the baby crib frame is suspended above the connecting frame 6, which is convenient for the clamping block 18 to clamp the baby crib frame, and also convenient for the second pressure sensor 27 to move to the bottom of the baby crib frame to perform a pressure test on it from the bottom.

[0032] The two sets of connecting rods 7 are fixedly connected to one end away from the connecting frame 6 with a block 8. The block 8 is arranged in an L-shaped structure, and its inner wall is equipped with an anti-wear pad, which not only enhances the friction between the inner wall of the block 8 and the baby crib frame, but also effectively prevents the baby crib frame from accidentally sliding into the inside of the block 8 during the movement of the connecting frame 6.

[0033] Fixed rods 9 are symmetrically installed on both sides of the connecting frame 6, and a tooth plate 10 is fixedly connected in the middle of the fixed rod 9. The diameter of the tooth plate 10 is greater than or equal to the diameter of the first gear 14 plus the second gear 21. Through this design, the tooth plate 10 will contact the first gear 14 and the second gear 21 during the sliding process, ensuring stable meshing transmission.

[0034] A hydraulic rod 5 is symmetrically installed on the top surface of the workbench 1, and the hydraulic rod 5 is fixedly connected to the connecting frame 6. A mounting plate 12 is fixedly connected to the inner wall of the support block 11, and a groove 1201 is provided on the top surface of the mounting plate 12, and a clamping assembly is installed inside the groove 1201, and the clamping assembly is used to clamp the baby bed frame. A support plate 19 is fixedly connected to the inner wall of the support block 11, and a through groove 1901 is provided on the top surface of the support plate 19, and a test assembly is installed inside the through groove 1901. An electric push rod 3 is fixedly connected to the bottom surface of the support frame 2, and a first pressure sensor 4 is installed on the output end of the electric push rod 3. Four bases 28 are installed at the bottom of the workbench 1.

[0035] In this embodiment, the crib frame to be tested is placed on the four blocks 8, and the hydraulic rod 5 is then started to push the connecting frame 6 to slide along the slide groove 101. During the sliding process, the fixing rods 9 and the tooth plates 10 on both sides are driven to move. When the tooth plates 10 move, they drive the clamping assembly to clamp the crib frame, and then the electric push rod 3 drives the first pressure sensor 4 to test the crib frame. After the test is completed, the hydraulic rod 5 drives the connecting rod 7 to return, and the staff can quickly and easily remove the tested crib frame from the block 8, and immediately replace it with a new crib frame for the next round of testing, thereby reducing the steps of repeatedly fixing and disassembling the crib frame for the staff, and improving work efficiency, while also reducing the labor intensity of the staff.

[0036] Embodiment 2:

[0037] Different from the first embodiment, Figure 3 and Figure 4 This embodiment also has the following further contents: the clamping assembly includes a rotating shaft 13 rotatably connected to the side wall of the support block 11, a first gear 14 is fixedly connected to the rotating shaft 13, the first gear 14 is meshed with the tooth plate 10, and a screw 15 is fixedly connected to one end of the rotating shaft 13 away from the support block 11, the screw 15 is rotatably connected to the inner wall of the groove 1201, a nut 16 is threadedly connected to the screw 15, a support rod 17 is fixedly connected to the top surface of the nut 16, and a clamping block 18 is fixedly connected to one end of the support rod 17 away from the nut 16.

[0038] In this embodiment, when the connecting frame 6 moves, the tooth plate 10 on its side wall meshes with the first gear 14, the first gear 14 is rotated by force, and drives the middle rotating shaft 13 to rotate, and the screw rod 15 at the bottom rotates immediately, and drives the nut 16 sleeved on the outside to slide along the groove 1201, and the support rod 17 and the clamping block 18 at the top move along the baby bed frame plate and clamp the baby bed frame in the middle, ensuring the stability of the baby bed frame during the strength test, effectively avoiding the possible sliding of the baby bed frame, thereby ensuring the accuracy and reliability of the test results. After the bed frame test is completed, the connecting frame 6 is reset under the action of the hydraulic rod 5, the tooth plate 10 will mesh with the first gear 14 again, and drive the screw 15 to rotate, and the nut 16 outside it moves along the direction of rotation of the screw 15, and drives the support rod 17 and the clamping block 18 to move backward, loosening the baby bed frame, thereby achieving that the baby bed frame will be firmly clamped by the clamping block 18 after the connecting frame 6 moves to the specified position, and after the test is completed, the connecting frame 6 can automatically loosen the baby bed frame when it resets and slides, thereby completely eliminating the tedious steps of the staff manually fixing the baby bed frame on the clamping block 18.

[0039] Implementation three:

[0040] Reference Figure 5 Compared with the first and second embodiments, the test assembly in this embodiment includes a transmission shaft 20 rotatably connected to the side wall of the support block 11, and a second gear 21 is fixedly connected to the transmission shaft 20. The second gear 21 is meshed with the toothed plate 10, and the first gear 14 and the second gear 21 are staggered on the same horizontal plane. The toothed plate 10 will mesh with the second gear 21 and the first gear 14 in sequence when in the same sliding trajectory to ensure that the first gear 14 and the second gear 21 can be smoothly driven to rotate during the sliding process.

[0041] One end of the transmission shaft 20 away from the support block 11 is fixedly connected to a screw rod 22, and the screw rod 22 is rotatably connected to the inner wall of the through groove 1901. A nut 23 is threadedly connected to the screw rod 22, and a long plate 24 is fixedly connected to the top surface of the nut 23. The end of the long plate 24 away from the nut 23 is fixedly connected to a fixing plate 25, and the top surface of the fixing plate 25 is fixedly connected to an electric telescopic rod 26, and a second pressure sensor 27 is installed on the top of the electric telescopic rod 26.

[0042] In this embodiment, the toothed plate 10 is also meshed with the second gear 21 under the drive of the connecting frame 6. The second gear 21 is rotated under the force, and the transmission shaft 20 in the middle thereof begins to rotate immediately, and drives the screw rod 22 to rotate. The screw nut 23 sleeved on the outside thereof slides in the through groove 1901 immediately, and the long plate 24 and the fixing plate 25 on the top slide toward the bottom of the baby bed frame. When the clamping block 18 clamps the baby bed frame, the second pressure sensor 27 is driven to rise by starting the electric telescopic rod 26, and the strength test of the baby bed frame is performed from bottom to top. This test method can ensure that the bottom surface of the baby bed frame is tested. Perform strength assessment to more fully understand its structural strength and stability. After the bottom surface test is completed, the electric telescopic rod 26 is started again to drive the second pressure sensor 27 to move downward. At this time, the baby bed frame is pressure tested from top to bottom through the first pressure sensor 4. When both sides are tested, the hydraulic rod 5 is started again to drive the connecting frame 6 to move backward and reset. The tooth plate 10 engages with the second gear 21 again, driving the screw rod 22 to rotate, and the nut 23 outside it moves backward immediately, driving the second pressure sensor 27 to move backward to above the support plate 19 to ensure that it will not hinder the reset of the connecting frame 6.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
