[0001] The utility model relates to the technical field of compressive strength testing of snap boxes, in particular to a compressive strength testing device for snap boxes. Background Technique

[0002] Packing boxes are mainly for facilitating transportation, loading and unloading, and storage. Generally, wooden boxes and corrugated solid wood pallets are used, and there are also those using tin barrels or galvanized iron barrels. A snap box means that the box body and the box cover of the packing box are connected by a snap type, which is convenient for accessing items.

[0003] During production, snap boxes need to be able to withstand a certain amount of pressure during transportation, so a compressive strength testing device for snap boxes is required. However, for the existing compressive strength testing devices, when conducting impact tests on snap boxes, generally a single instantaneous impact test is carried out on the snap boxes to test the maximum impact force that the snap boxes can withstand. However, the impacts that snap boxes receive during transportation are generally continuous impacts. Therefore, only conducting a single impact cannot detect various compressive properties of the snap boxes. For this reason, a compressive strength testing device for snap boxes is proposed. Content of the Utility Model

[0004] In view of the above problems of the existing compressive strength testing devices, when conducting impact tests on snap boxes, generally a single instantaneous impact test is carried out on the snap boxes, the present utility model is proposed.

[0005] To solve the above technical problems, the present utility model provides the following technical solution: A compressive strength testing device for snap boxes, which includes a support platform and a fixed top frame. The lower end of the fixed top frame is fixed to the upper surface of the support platform. A ring plate is arranged between the support platform and the fixed top frame. The outer ring surface of the ring plate is fixedly sleeved with a sleeve disc. The outer surface of the sleeve disc is fixedly sleeved with an external toothed ring.

[0006] Preferably, the stepped structure includes a stepped plate. One end of the stepped plate is elastically rotatably connected to the ring plate. A top rod is arranged below the stepped plate. A top ring is arranged below the ring plate. The lower end of the top rod is fixed to the upper surface of the top ring. The upper surface of the sleeve disc is rotatably penetrated by a plurality of threaded rods. The outer ring surface of the top ring is threadedly sleeved on the outer surface of the threaded rods.

[0007] Preferably, a bevel block is arranged on one side of the stepped plate away from the lower ejector rod, and the bevel block is fixed to the upper surface of the ring plate.

[0024] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0025] Referring to Figure 1-6 , as an embodiment of the present utility model, a compression test device for a snap box is provided. This compression test device for a snap box includes a support platform 1 and a fixed top frame 2. The lower end of the fixed top frame 2 is fixed to the upper surface of the support platform 1. A ring plate 8 is arranged between the support platform 1 and the fixed top frame 2. The outer ring surface of the ring plate 8 is fixedly sleeved with a sleeve disc 3. The outer surface of the sleeve disc 3 is fixedly sleeved with an external gear ring 7. The outer surface of the external gear ring 7 is rotatably sleeved with a notch ring frame 6. The upper end of the notch ring frame 6 is fixed to the upper end of the fixed top frame 2. A power transmission structure 4 is meshed with the outer ring surface of the external gear ring 7. The power transmission structure 4 is connected to the fixed top frame 2. The power transmission structure 4 includes a motor 41 and a meshing gear 42. The meshing gear 42 is meshed with the outer ring surface of the external gear ring 7. The meshing gear 42 is fixedly sleeved on the output end of the motor 41. The motor 41 is connected to the fixed top frame 2. The motor 41 provides a rotational force to the ring plate 8 through the meshing of the meshing gear 42 with the external gear ring 7.

[0026] A plurality of uniformly distributed stepped structures 5 are installed on the upper surface of the annular plate 8. A prism rod 9 is arranged at the inner ring axis of the annular plate 8. A hammering structure 11 is fixed at one end of the prism rod 9 located below the annular plate 8. The upper end of the fixed top frame 2 is slidably sleeved on the upper end of the prism rod 9. A plurality of contact rods 10 are arranged at equal distances above the annular plate 8. The number of the stepped structures 5 is an integer multiple of the number of the contact rods 10. The lower end of the contact rod 10 has a rounded corner. The upper end of the contact rod 10 is fixed to the prism rod 9. A pressure spring 12 is sleeved on one end of the prism rod 9 located above the fixed top frame 2. Both ends of the pressure spring 12 are fixed to the upper end of the prism rod 9 and the upper surface of the fixed top frame 2 respectively. The pressure spring 12 has a tendency to drive the prism rod 9 to move downward, so that the contact rod 10 contacts the annular plate 8. At this time, the prism rod 9 hammers the buckle box above the support table 1 through the hammering structure 11.

[0027] The stepped structure 5 includes a stepped plate 51. One end of the stepped plate 51 is elastically and rotatably connected to the annular plate 8. The stepped plate 51 has a tendency to approach the annular plate 8. A top rod 53 is arranged below the stepped plate 51. A top ring 52 is arranged below the annular plate 8. The lower end of the top rod 53 is fixed to the upper surface of the top ring 52. A plurality of threaded rods 54 penetrate through the upper surface of the sleeve disc 3 in a rotating manner. The outer ring surface of the top ring 52 is threadedly sleeved on the outer surface of the threaded rod 54. A small gear 56 is fixedly sleeved at one end of the threaded rod 54 located above the sleeve disc 3. An internal gear ring 57 is rotatably inserted into the upper surface of the sleeve disc 3. The small gear 56 meshes with the inner ring surface of the internal gear ring 57. Rotating the internal gear ring 57 can drive a plurality of small gears 56 to rotate synchronously, so that the top ring 52 changes the height of the top rod 53 by meshing with a plurality of threaded rods 54, and further changes the inclined height of the stepped plate 51, controls the falling height of the contact rod 10, and changes the hammering force of the hammering structure 11 on the buckle box.

[0028] An inclined block 55 is arranged on one side of the stepped plate 51 away from the lower top rod 53. The inclined block 55 is fixed to the upper surface of the annular plate 8. The upper surface of the inclined block 55 is an inclined surface. The upper end of the inclined block 55 is located above the stepped plate 51. The arrangement of the inclined block 55 facilitates the movement of the contact rod 10 from the annular plate 8 to the stepped plate 51.

[0029] During use, place the buckle box to be detected on the support table 1. The pressure spring 12 drives the contact rod 10 to have a downward movement tendency through the ridge rod 9, so that the contact rod 10 can contact the ring plate 8 and the stepped plate 51. The motor 41 drives the meshing gear 42 to mesh with the external tooth ring 7, and drives the ring plate 8 to rotate through the sleeve disc 3. When the ring plate 8 rotates, the contact rod 10 continuously moves onto the stepped plate 51 to drive the pressure spring 12 to deform. Then, after the contact rod 10 separates from the upper end of the stepped plate 51, the pressure spring 12 drives the contact rod 10 to quickly move downward to contact the ring plate 8 through the ridge rod 9. When the ridge rod 9 moves downward, it drives the hammering structure 11 to hammer the buckle box. During the continuous rotation of the ring plate 8, the contact rod 10 continuously moves from the ring plate 8 to the stepped plate 51, and then falls from the upper end of the stepped plate 51, so that the hammering structure 11 continuously hammers the buckle box below, for the continuous compressive capacity test of the buckle box.
