Technical Field

[0001] The utility model relates to the technical field of sanitary ceramic testing, in particular to a sanitary ceramic load testing machine. Background Art

[0002] Sanitary ceramics refer to ceramic utensils used for hygiene and washing. In the production of sanitary ceramics, toilets are an important part of the bathroom, and their quality is directly related to people's quality of life. The commonly used toilet quality inspection standards today mainly include indicators such as appearance, water flow performance, impact resistance, wear resistance, and health and safety.

[0003] To ensure that under normal use, the toilet will not be broken when an adult sits or squats on it, the load-bearing capacity of the toilet is crucial to the product. Once the toilet is broken, ceramic fragments will be produced, causing harm to the human body. Therefore, the load-bearing capacity and impact resistance test of the toilet has become one of the important standards for toilet quality inspection. However, most of the testing machines on the market that detect the load of sanitary ceramics currently use servo motors to provide load force to drive the clamping plate to apply load force to the sanitary ceramic products for testing. However, this type of testing machine that uses servo motors to provide load force has a high failure rate and high production cost. At the same time, the structure of the existing load testing machine for fixing ceramic products is fixed, and cannot meet the requirements for the inspection of ceramic products of various specifications. Therefore, it is urgent to design a sanitary ceramic load testing machine with low failure rate, high cost performance, and capable of meeting the inspection of most product models.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0022] like Figures 1 to 3 As shown, the utility model provides a sanitary ceramic load testing machine, comprising: a support assembly 2, a load assembly 1 spanning the support assembly 2, and a fixed assembly 3 movably arranged on the support assembly 2; the load assembly 1 comprises a door-type frame 11, cylinder lifting modules 12 are arranged on both sides of the door-type frame 11, and a clamping plate 13 is arranged on the lifting ends of the two cylinder lifting modules 12, the clamping plate 13 is arranged above the support assembly 2, and a pressure sensor 14 is arranged on the clamping plate 13, and the cylinder lifting module 12 drives the clamping plate 13 to move up and down to apply different load pressures to the sanitary ceramic product 4 to be tested.

[0023] In this embodiment, a mounting base 111 is provided at the bottom end of the door-shaped frame 11, and the inspector can stably fix the testing machine on the test site by pre-embedded screws. The support assembly 2 is fixedly connected to the load assembly 1. Preferably, the pressure sensor 14 in this embodiment is an S-type tension and compression weighing sensor. In this embodiment, the inspector can choose to install it on the fixing component 3 or directly place it on the supporting component 2 according to the type of sanitary ceramic product to be inspected. If the sanitary ceramic product 4 to be inspected is wall-mounted, it needs to be installed on the fixing component 3 and moved to just below the clamping plate 13. If the sanitary ceramic product 4 to be inspected is a box-type, it only needs to be placed on the supporting platform 2. Moreover, the fixing component 3 movably arranged on the supporting component 2 can also move back and forth according to the specifications of the sanitary ceramic product 4 to be inspected to meet the spatial detection needs of products of different specifications. After fixing the sanitary ceramic product to be inspected, the inspector can slowly rotate the precision pressure regulating valve clockwise (increase) or counterclockwise (decrease) according to the test requirements to control the air source pressure. The pressure sensor 14 can transmit the load data to the distribution box in real time until the distribution box displays the pressure to be tested. At this time, press the "start" button of the distribution box to control the cylinder lifting module 12 to move up and down, driving the clamping plate connected to it to clamp the sanitary ceramic product to be inspected according to the set load pressure, thereby realizing the load resistance detection test. At the same time, this load testing machine is also equipped with timing electrical components, and the time can be adjusted according to the testing needs.

The pressing beam 121 is provided with a tie rod bolt 122 that is detachably connected to the pressing plate 13, and the pressure sensor 14 is installed on the tie rod bolt 122. The setting of the pressing beam 121 can make the load force transmitted to the pressing plate 13 by the two groups of cylinder lifting modules more uniform and stable. At the same time, through the tie rod bolt 122, the inspection personnel can quickly install and replace the pressing plates 13 of different sizes according to the specifications of the sanitary ceramic products to be inspected. The structural design is simple, practical, and easy to operate.

The sliders 150 and the slide rails 151 drive the clamping beam 121 to move up and down, realizing the synchronous movement of the two sets of lifting cylinders 120, and ensuring the stability of the clamping beam 121 sliding up and down.

[0027] Specifically, Figure 1 As shown, in this embodiment, the support assembly 2 includes a support frame 21, and an adjusting foot 22 is provided at the bottom of the support frame 21 to adjust the horizontality of the support assembly 2 on the ground.

Preferably, in this embodiment, a nut can be passed through the pressing members 16 to tighten the lower surface of the support frame 21, thereby transmitting the load force to the door-shaped frame 11 itself, preventing the support frame 21 from being subjected to too much force and damaging the adjusting foot 22, thereby affecting the stability of the placement of the sanitary ceramic product to be tested and affecting the accuracy of the test results.

[0029] Specifically, Figure 2 As shown, in this embodiment, the fixing assembly 3 includes a fixing bracket 31, a mounting plate 32 and a sliding member 33 located at the bottom end of the fixing bracket 31.

The mounting plate 32 is mounted on the fixing bracket 31 perpendicular to the direction of the support plate 23. The mounting plate 32 can be used to fix and install the wall-mounted sanitary ceramic product 4 to be tested. Preferably, in this embodiment, the sliding member 33 is a bolt or a nut. The diameter of the bolt is smaller than the width of the first slide groove 24, and it can slide smoothly along the first slide groove 24.

[0030] Specifically, Figure 2 and Figure 3As shown, in this embodiment, the upper end of the fixed bracket 31 is provided with a second slide groove 310 along the Y-axis direction, and the upper end of the door-shaped frame 11 is provided with a guide member 110 passing through the second slide groove 310, and the fixed bracket 31 slides forward and backward along the first slide groove 24 and the second slide groove 310.

[0031] Specifically, Figures 1 to 3 As shown, in this embodiment, the mounting plate 32 is provided with a plurality of mounting holes 320 for fixing the ceramic product 4 to be tested. The mounting holes are a plurality of oblong holes staggered horizontally and vertically, and the inspector can fix the wall-mounted sanitary ceramic product 4 to be tested on the mounting plate 10 through the plurality of mounting holes 320.

[0032] The working principle of the load testing machine is as follows:

[0033] (1) When a product load test is required, the test personnel shall fix and install the product according to the product type and adjust the required gas source pressure and timing time;

[0034] (2) Press the "Start" button on the distribution box to start the test, control the cylinder lifting module 12 to descend, and slowly press the pressing plate 13 down until it contacts the sanitary ceramic product to be tested until the pressure value does not change;
