Description

Technical Field

[0001] The utility model relates to a quality inspection device for sealing products, in particular to a silicone magnet impact test bench. Background Art

[0002] The description of this part only provides background information related to the disclosure of the utility model, and does not constitute prior art.

[0003] The structure of a domestic gas water heater requires good sealing operation. Generally, at present, a silicone door frame sealing strip (hereinafter referred to as the sealing strip) formed by vulcanizing an amorphous silica material with a three-dimensional network structure is used for sealing. At the same time, in order to facilitate on-site assembly and realize the detachable use of the door body, blind holes are provided on the sealing strip, and magnets are adhesively fixed in the blind holes with glue, so that the sealing strip can be detachably connected to the metal door body.

[0004] However, the sealing strip is made of silicone material. However, since silicone is a porous structure and the surface of the magnet is very smooth after nickel plating, it is very difficult to firmly bond the two. During the transportation, assembly, and disassembly of the components of the gas water heater product, it is very easy to encounter the situation of product vibration or dropping. If the magnet is not firmly bonded, the magnet will fall off from the blind hole, causing the entire sealing strip to lose its sealing function. Therefore, the impact resistance of the magnet bonded to the sealing strip is one of the most important items for evaluating the product quality, and it is necessary to design a test device to conduct relevant tests.

[0005] At present, there is no silicone magnet impact test bench that can solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a silicone magnet impact test bench, which can be repeatedly lifted and impacted through the cooperation of a sliding mechanism and a guide rod, and quickly and efficiently test the adhesion strength between the sealing strip and the magnet.

[0007] In order to achieve the above purpose, the utility model discloses a silicone magnet impact test bench for detecting the adhesion strength between a sealing strip and a magnet. One side of the sealing strip is provided with a blind hole matching the volume of the magnet, and the magnet is adhesively fixed in the blind hole with glue.

[0011] An anti-fall block, which is away from the adsorption plate and is fixedly sleeved on the guide rod toward one side of the top end of the guide rod;

[0012] A fixed plate, the fixed plate is fixed on the bracket, and the fixed plate is provided with an insert plate that can move forward and backward along a direction that is not parallel to the sliding direction of the sliding mechanism;

[0013] Among them, the guide sleeve includes a step portion matching the size of the plug plate. When the sliding mechanism is lifted to a first height, the plug plate can be inserted into the slot and abut against the step portion, so that the sliding mechanism is limited; when the plug plate is moved away from the step portion, the sliding mechanism falls freely until the adsorption plate abuts against the anti-fall block, and the sliding mechanism falls to a second height.

[0014] Furthermore, the fixing plate is provided with a slot, the slot matches the size of the plug-in board, and the plug-in board can be detachably inserted into the slot.

[0016] Furthermore, the anti-fall block is provided with a threaded hole, and a fastener is used to sleeve and fix the anti-fall block at the bottom end of the guide rod through the threaded hole.

[0017] Furthermore, the height difference between the first height and the second height is 260 mm.

[0018] Furthermore, the adsorption plate is made of iron, and the size of the adsorption plate matches the sealing strip.

[0033] See also Figures 1-3 , is a silicone magnet impact test bench of this embodiment, used to detect the adhesion strength between the sealing strip 100 and the magnet 200, wherein one side of the sealing strip 100 is provided with a blind hole matching the volume of the magnet 200, and the magnet 200 is fixed in the blind hole by glue; wherein the silicone magnet impact test bench includes:

[0034] Bracket 1;

[0035] A guide rod 2, the guide rod 2 is vertically arranged, the guide rod 2 has a top end and a bottom end arranged opposite to each other, and the top end of the guide rod 2 is fixed on the bracket 1;

[0036] The sliding mechanism 3 includes a guide sleeve 31 and an adsorption plate 32 which are fixedly connected. The guide sleeve 31 and the adsorption plate 32 are slidably sleeved on the guide rod 2, wherein the guide sleeve 31 is arranged on a side away from the adsorption plate 32 and toward the top end of the guide rod 2, and the adsorption plate 32 is arranged on a side away from the guide sleeve 31 and toward the bottom end of the guide rod 2, and the sealing strip 100 is attached to the side of the adsorption plate 32 away from the guide sleeve 31 through the magnet 200;

[0037] The anti-fall block 4 is fixedly sleeved on the guide rod 2 with one side facing away from the adsorption plate 42 and toward the top of the guide rod 2;

[0038] A fixed plate 5, the fixed plate 5 is fixed on the bracket 1, and a plug plate 6 is provided on the fixed plate 5 and can move forward and backward along a sliding direction that is not parallel to the sliding direction of the sliding mechanism 3;

[0039] Among them, the guide sleeve 31 includes a step portion 311 that matches the size of the plug plate 6. When the sliding mechanism 3 is lifted to the first height, the plug plate 6 can be inserted into the slot and abut against the step portion 311, so that the sliding mechanism 3 is limited; when the plug plate 6 is removed from the step portion 311, the sliding mechanism 3 falls freely until the adsorption plate 32 abuts against the anti-fall block 4, and the sliding mechanism 3 drops to the second height.

[0040] For the above structure, during installation, the operator first needs to prepare a bracket 1 with a preset height, and the height of the bracket 1 should be at least higher than the vertical height of the guide rod 2. At the same time, after fixing one end of the guide rod 2 at the middle position of the top of the bracket 1, the guide sleeve 31 and the adsorption plate 32 of the sliding mechanism 3 are respectively installed on the guide rod 2, and finally the anti-fall block 4 is installed on the end of the guide rod 2. Similarly, the fixing plate 5 is installed at the middle position of the top of the bracket 1 corresponding to the installation position of the guide rod 2, and the height of the fixing plate 5 for inserting the plug 6 can be adjusted so that the plug 6 can contact the step 311 of the guide sleeve 31 after insertion.

[0041] Through the above structure, when in use, the operator only needs to adsorb the sealing strip 100 to be tested on the bottom surface of the adsorption plate 32 of the sliding mechanism 3 through the magnet 200, and then lift the sliding mechanism 3 to the position of the first height, and move the plug plate 6 at the fixed plate 5 to the step portion 311, so that the step portion 311 and the plug plate 6 abut each other, so that the sliding mechanism 3 drives the sealing strip 100 to be tested to be in a static state at the first height. Then, the operator pulls the plug plate 6 away from the step portion 311, so that the sliding mechanism 3 loses the support of the plug plate 6 and starts to fall freely, until the sliding mechanism 3 falls to the bottom surface of the adsorption plate 32 and collides with the anti-fall block 4 at the bottom end of the guide rod 2, and the sliding mechanism 3 is limited. At this time, the sliding mechanism 3 is at the second height. Since the sliding mechanism 3 falls freely and collides with the anti-fall block 4, the vibration generated by the collision shakes the sealing strip 100 off, and generates a large vibration to the magnet 200 on the sealing strip 100. At this time, if the adhesion strength of the magnet 200 in the sealing strip 100 is not enough, the magnet 200 will fall off from the blind hole of the sealing strip 100, and the product will be unqualified. If the adhesion strength of the magnet 200 in the sealing strip 100 is sufficient, the magnet 200 will not fall off from the blind hole of the sealing strip 100, and the product will be qualified.

[0042] During the above-mentioned use process, the operator only needs to place the sealing strip 100 to be detected on the adsorption plate 32 used to adsorb the magnet 200 adhered to the sealing strip 100, and lift the sliding mechanism 3 to the position at the first height. Insert the insertion plate 6 to limit the stepped portion 311, and the preparation work is completed. By directly sliding the insertion plate 6, the impact vibration test is realized. The height difference between the first height and the second height is 260 mm. In some embodiments, it can be stably adjusted according to actual needs. Only the height of the anti-fall block 4 needs to be adjusted. The process is simple, the reproducibility and consistency of the experiment are high, and the test of the adhesion strength between the sealing strip 100 and the magnet 200 can be significantly improved.

[0043] Further, a slot is provided on the fixing plate 5, and the size of the slot matches that of the insertion plate 6. The insertion plate 6 is detachably inserted into the slot. At the same time, a through hole for facilitating the operator to grasp and used to control the sliding of the insertion plate 6 in the slot is provided at a position outside the slot of the insertion plate 6. The contact portion between the insertion plate 6 and the stepped portion 311 is provided with a U-shaped groove matching the contour of the stepped portion. Specifically, the through hole of the insertion plate 6 is set to a diameter equivalent to the thickness of the operator's finger, so as to facilitate the quick pulling of the insertion plate 6 directly by hand. As Figure 2 shown, the contact portion between the insertion plate 6 and the stepped portion 311 is provided with a U-shaped groove, which enables the insertion plate 6 to better limit the stepped portion 311 in the sliding mechanism 3 and prevent the guide sleeve 31 of the sliding mechanism 3 from being skewed when at the first height.

[0044] Further, the anti-fall block 4 has a threaded hole, and the fastener sleeves and fixes the anti-fall block 4 at the bottom end of the guide rod 2 through the threaded hole. Through the setting of the cooperation between the threaded hole and the fastener, the operator can quickly adjust the fixing tightness of the anti-fall block 4. After the fastener is adjusted and loosened, the height of the anti-fall block 4 can be adjusted again, realizing the adjustment of the height difference between the first height and the second height, flexibly changing the vibration amount, and being applicable to a variety of strength test standard ranges.

[0045] Further, the adsorption plate 32 is made of iron, and the size of the adsorption plate 32 matches that of the sealing strip 100. Specifically, in this embodiment, 8 magnets 200 are arranged at intervals on the sealing strip 100 and are arranged around the sealing strip 100 at equal distances. The adsorption plate 32 is also set as a rectangular panel with a geometric shape equivalent to that of the sealing strip 100, which is beneficial for each magnet 200 on the sealing strip 100 to be evenly stressed during the falling process.

[0046] Furthermore, the guide rod 2 is passed through the middle position of the adsorption plate 32. With the above structure, when the adsorption plate 32 falls, the impact area with the anti-falling block 4 is the middle position of the adsorption plate 32, making the overall vibration force on the adsorption plate 32 more balanced. When a plurality of magnets 200 arranged at intervals are provided on the sealing strip 100, each magnet 200 can obtain a substantially equivalent vibration force.

[0047] Furthermore, as Figure 1 shown, a backing plate 33 is further included between the guide sleeve 31 and the adsorption plate 32. The guide sleeve 31, the adsorption plate 32 and the backing plate 33 are fixedly connected by screws and sleeved on the guide rod 2. The purpose is to prevent the position where the guide sleeve 31 contacts the adsorption plate 32 from exerting excessive pressure on the adsorption plate 32, resulting in possible deformation of the adsorption plate 32 after falling impact vibration, so as to extend the service life of this embodiment.

[0048] The content disclosed above is only the preferred feasible embodiment of the present invention, and does not limit the scope of the patent application of the present invention. Therefore, all equivalent technical changes made by using the content of the specification and drawings of the present invention are included in the scope of the patent application of the present invention.

[0049] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments.

[0050] Although the present application is depicted through embodiments, those of ordinary skill in the art know that the present application has many variations and changes without departing from the spirit of the present application. It is hoped that the appended embodiments include these variations and changes without departing from the present application.
