Description

Technical Field

[0001] The utility model relates to the technical field of pressure-resistant testing equipment, in particular to a pressure-resistant testing equipment for producing coated umbrella frames. Background Art

[0002] As the skeleton of an umbrella, the umbrella frame is generally composed of multiple ribs and connectors. Based on traditional umbrella frame materials (such as metal, plastic and fiber, etc.), the coated umbrella frame adopts coating technology to form a thin film on the surface of the umbrella frame. This film is composed of polymers, metal oxides and other materials, and has excellent wear resistance, corrosion resistance and UV resistance. Through this film, compared with traditional umbrella frames, the coated umbrella frame can effectively resist the erosion of the external environment on the surface of the umbrella frame, such as oxidation and corrosion, thereby extending the service life of the umbrella frame, while maintaining the beauty and functionality of the umbrella frame, and can reduce the frequency of replacing umbrellas due to damage to the umbrella frame, thereby reducing the cost of use.

[0003] In order to verify the safety and product quality of the coated umbrella frames, it is necessary to perform a voltage resistance test on the coated umbrella frames, including a voltage resistance test and a pressure resistance test. The voltage resistance test is an important means to verify whether the coated umbrella frames will be damaged or fail when subjected to a certain voltage. The verification test can ensure that the coated umbrella frames will not cause safety accidents due to electrical factors under normal use or extreme conditions, thereby ensuring the safety of users. The pressure resistance test is one of the important indicators for evaluating the quality of the coated umbrella frames. However, in the actual voltage resistance test process of the coated umbrella frames, it is found that in the traditional voltage resistance test process of the coated umbrella frames, the voltage resistance test and the pressure resistance test are usually carried out in steps. As a result, the coated umbrella frames need to be clamped multiple times, which increases the test steps of the coated umbrella frames and reduces the production inspection efficiency of the coated umbrella frames. For this reason, the present application proposes a voltage resistance testing device for the production of coated umbrella frames to solve the above problems. Utility Model Content

[0031] like Figure 1 As shown, an embodiment of the utility model provides a pressure-resistant testing device for the production of coated umbrella frames, including a testing platform 1; a conductive clamp 3 arranged on the top of the testing platform 1, a pair of conductive clamps 3 are provided, used to horizontally clamp the coated umbrella frame and conduct the circuit with the coated umbrella frame; a voltage regulating component 8 arranged on the testing platform 1, used to apply voltage to the pair of conductive clamps 3; an L-shaped fixed arm 4 fixed on the top of the testing platform 1, a hydraulic push rod 5 is vertically installed on the top of the L-shaped fixed arm 4, and the telescopic end of the hydraulic push rod 5 is provided with a pressure detection head 6 for pressing down the coated umbrella frame and measuring the pressure. Through this structural method, by arranging the voltage regulating component 8 and the pressure detection head 6 on the testing platform 1, the coated umbrella frame is conductively clamped by a pair of conductive clamps 3, and the voltage regulating component 8 is used to guide the pressure downward. The electric clamp 3 sequentially transmits the rated AC voltage and the rated DC voltage to simulate the AC voltage environment or DC voltage environment that the coated umbrella frame may encounter in actual use, and observes whether the coated umbrella frame has abnormal phenomena, such as breakdown, flickering, etc., so as to realize the voltage resistance detection of the coated umbrella frame. By starting the hydraulic push rod 5 to push the pressure detection head 6 to continuously apply pressure to the coated umbrella frame, observing the deformation of the coated umbrella frame, and recording the instantaneous pressure when the coated umbrella frame is deformed, the pressure resistance detection of the coated umbrella frame can be realized. The coated umbrella frame pressure resistance detection equipment integrates voltage resistance detection and pressure resistance detection, and can simultaneously realize voltage resistance detection and pressure resistance detection of the coated umbrella frame, without the need to repeatedly clamp the coated umbrella frame, thereby reducing the operation steps and improving the efficiency of production detection of the coated umbrella frame.

The lower surface of the pressure block 23 is set as an arc concave surface, which is used to adapt to the coated umbrella frame with a circular center structure.

[0038] The working principle provided by the utility model is that when in use, the coated umbrella frame is horizontally placed between two pairs of clamping blocks 15, and the electric push rod 16 is used to push the clamping block 15 close to another clamping block 15, and the arc-shaped grooves 19 on the opposite sides of each pair of clamping blocks 15 are used to clamp the two ends of the coated umbrella frame with buckles, and at the same time, the conductive contact piece 20 is in conductive contact with the coated umbrella frame, thereby, the high-voltage generator 9 is connected to the external power supply, and the voltage regulator 10 is cooperated to sequentially transmit the rated AC voltage and the rated DC voltage to the conductive contact piece 20, so as to simulate the AC voltage environment or DC voltage environment that the coated umbrella frame may encounter in actual use, and observe whether the coated umbrella frame has abnormal phenomena, such as breakdown, flickering, etc., so as to realize the voltage resistance detection of the coated umbrella frame. Furthermore, there is no need to repeatedly clamp the coated umbrella frame. The hydraulic push rod 5 is started to push the pressure sensor 22 and the pressure block 23 downward, and pressure is continuously applied to the coated umbrella frame. The deformation of the coated umbrella frame is observed, and the pressure sensor 22 is used to record the pressure applied to the coated umbrella frame. The instantaneous pressure when the coated umbrella frame is deformed can be recorded to realize the pressure resistance detection of the coated umbrella frame.
