[0007] Further, anti-slip feet are provided at the four corners of the bottom plate.
[0008] The above-mentioned heavy object impact test device for suitcases is further provided with limit triggers, which are respectively located on the upper side and the lower side of the electric lead screw.
[0009] Further, the motor of the electric lead screw is arranged at the 1 / 3 height of the profile bracket.
[0010] Further, the side wall of the guide cylinder is provided with an opening, and the size of the opening is larger than the outer dimension of the weights, which is convenient for directly placing the weights into the guide cylinder from the side during the test.
[0011] Further, the test surface of the weight is spherical; weights of different specifications can be selected according to the quality grade requirements, such as 2.5 kg, 3 kg, 4 kg, 5 kg, and 7.5 kg.
[0012] Advantages of the utility model:
[0013] The luggage heavy object impact test device provided by the utility model uses a combination of weights and electromagnets to simulate the actual use situation of the luggage being repeatedly impacted by heavy objects, and observes the loss results.
[0014] The utility model is a fully automated device, which only requires single-person operation to quickly perform multiple tests, with high efficiency, simple operation, and good adaptability.
[0015] The technical solution of the utility model will be illustrated by way of examples in conjunction with the accompanying drawings and embodiments. Description of the drawings

[0021] 11 Upper limit trigger Detailed implementation manners
[0022] The specific embodiments described herein are only used to explain the technical solution of this patent, rather than limiting the disclosed technical solution. Additionally, it should be noted that for the sake of convenience of description, only parts related to the technical solution of this application are shown in the drawings, rather than all the structures.
[0023] Before discussing the exemplary embodiments in more detail, it should be mentioned that if the structures of the device components and / or modules mentioned in the embodiments are not described in detail, they are understandable to those skilled in the art according to the existing disclosed technologies or commercially available products.
[0024] Reference Figure 1, the heavy object impact test device for luggage provided by this embodiment includes a bottom plate 1, a profile bracket 2, an electric screw rod 3, a vertical guide rail 4, a vertical slider 5, a fixing bracket 6, a guide cylinder 7, a weight 8, an electromagnet 9 and an electric control cabinet 10. The profile bracket 2 is vertically fixed on the bottom plate 1, and the electric screw rod 3 is vertically arranged on the profile bracket 2; the vertical guide rail 4 is fixed on the profile bracket 2, on both sides of the electric screw rod 3; the vertical slider 5 is arranged on the vertical guide rail 4; the middle of the fixing bracket 6 is fixed on the steering nut of the electric screw rod 3, and both ends of the fixing bracket 6 are respectively fixed on the vertical slider 5; the guide cylinder 7 is vertically arranged on the fixing bracket 6, the electromagnet 9 is arranged on the top of the guide cylinder 7, the weight 8 is placed in the guide cylinder 7 during testing, and the electric control cabinet 10 is used to control the motor of the electric screw rod 3 and the electromagnet 9.
[0025] To better maintain the stability of the entire device when impacting the sample, the preferred solution is to set anti-slip feet 101 at all four corners of the bottom plate 1.
[0026] To avoid malfunctions caused by over-range, a limit trigger 11 can be set at the upper side position of the electric screw rod 3. After rising to the limit height, the motor stops running; at the same time, a limit trigger is also set on one side of the lower position, and the motor stops when descending to the limit.
[0027] Considering the setting of the sizes of various types of luggage and the impact height in the market, the motor of the electric screw rod 3 is preferably located at the 1 / 3 height of the profile bracket 2.
[0028] To facilitate placing the weight into the guide cylinder from the side, an opening 701 can also be set on the side wall of the guide cylinder 7, and the size of the opening 701 should be larger than the outer dimension of the weight.
[0029] The weight 8 can be configured with different specifications of weights according to the quality grade requirements, such as 2.5 kg, 3 kg, 4 kg, 5 kg and 7.5 kg grades. The test surface of the weight 8 is generally spherical.
[0030] When using the heavy object impact test device for luggage provided by the above embodiment, during testing,
[0031] First, place the luggage sample on the bottom plate, and then operate the screw rod to lower or raise the guide cylinder to the test impact height.
[0032] Power on the electromagnet, and then attract the weight to the electromagnet.
[0033] Start the test. The electromagnet is powered off, and the weight freely falls in the guide cylinder and impacts the luggage below. The electromagnet is powered on again, and the weight is adsorbed; then the electromagnet is powered off for the second time, and the weight falls to impact the sample. According to the set number of test times, impact repeatedly.
[0034] The electric lead screw can adjust the impact height according to the sample size and requirements, so it can test various suitcases with different specifications on the market. At the same time, weights can be selected according to various quality grade requirements, and the impact times, heights, etc. can be set.
[0035] The suitcase heavy object impact testing device provided by the above embodiments can test multiple samples simultaneously by one person, with high efficiency. According to the experimental test results, the data repeatability is also very good, meeting the requirements of quality inspection and evaluation.
