[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a cookware compression strength testing device described in the present invention includes a testing machine 1, a placing mechanism 2 is installed on the testing machine 1, an adjusting mechanism 3 is installed on the placing mechanism 2, a limiting mechanism 4 is installed on the placing mechanism 2, a connecting mechanism 5 is installed on the placing mechanism 2, a protective mechanism 6 is installed on the testing machine 1, and an opening and closing mechanism 7 is installed on the protective mechanism 6.

[0032] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the placement mechanism 2 includes a placement plate 201, and the testing machine 1 is equipped with a placement plate 201. Two symmetrically distributed support blocks 202 are installed on the top of the placement plate 201. The tops of the opposite sides of the two support blocks 202 are rotatably connected with rotating blocks 204 respectively. One side of the rotating block 204 is an arc structure. The installation of the placement plate 201 facilitates the connection of the two support blocks 202. The installation of the two support blocks 202 can support the side wall of the circular cookware, which is beneficial to subsequent strength testing. The two symmetrical rotating blocks 204 are connected to achieve a close fit between the rotating block 204 and the side wall of the cookware, making the cookware placement more stable.

[0033] Specifically, Figure 2 and Figure 3As shown, the support block 202 is a trapezoidal structure, and a plurality of equally spaced protective strips 203 are respectively installed on one side of the two rotating blocks 204. The protective strips 203 are made of rubber material. The installation of the rubber strips is conducive to increasing the friction between the side wall of the pot and the side wall of the rotating block 204, so that the pot is not easy to slide after being placed, thereby achieving a better detection effect.

[0034] Specifically, Figure 3 As shown, the adjustment mechanism 3 includes a slider 304, and two sliders 304 are slidably connected at the inner center line of the placement plate 201, and the tops of the two sliders 304 extend to the outer side of the top of the placement plate 201 respectively, and the tops of the two sliders 304 are respectively connected to the bottoms of the two support blocks 202, and the two support blocks 202 are slidably connected to the top of the placement plate 201 through the two sliders 304, and a bidirectional screw rod 303 is rotatably connected at the inner center line of the placement plate 201, and both ends of the bidirectional screw rod 303 are threadedly connected to the center lines of the two sliders 304, and one end of the bidirectional screw rod 303 extends to the outer side of the placement plate 201, and the installation of the two sliders 304 is conducive to the connection of the two support blocks 202, and by driving the bidirectional screw rod 303, the bidirectional screw rod 303 drives the two sliders 304 to move synchronously in opposite directions under the cooperation of the thread, so that the two support blocks 202 are brought close to or away from each other, which is conducive to the placement of pots with different diameters, increases the detection range, and is more convenient to operate.

[0035] Specifically, Figure 2 , Figure 3 and Figure 4 As shown, a driving disk 302 is installed at one end of the bidirectional screw rod 303, and a plurality of dust covers 301 are slidably connected at the top center line of the placement plate 201.

The installation of the driving disk 302 facilitates the drive control of the bidirectional screw rod 303, and the operation is more convenient and labor-saving. The installation of the plurality of dust covers 301 facilitates the shielding and protection of the sliding space between the support blocks 202 to prevent debris from entering and causing the support blocks 202 to be unable to move.

[0036] Specifically, Figure 2 , Figure 4 and Figure 5As shown, the limiting mechanism 4 includes a card plate 401, a card plate 401 is installed inside one side of the placement plate 201, the card plate 401 is slidably connected to the inside of the placement plate 201 through a resistance spring 404, the card plate 401 is an "L"-shaped structure, and the side wall of one end of the card plate 401 extends to the outside of the placement plate 201, a rubber sleeve 403 is installed on the outside of one end of the bidirectional screw rod 303, and the rubber sleeve 403 is rotatably connected to the inside of the placement plate 201 through the bidirectional screw rod 303, and an anti-skid pad 402 is installed on the other end of the card plate 401. 402 is an arc-shaped structure, and the anti-skid pad 402 is in contact with the side wall of the rubber sleeve 403. Through the contact of the contact spring 404, the card plate 401 drives the anti-skid pad 402 to contact the side wall of the rubber sleeve 403 tightly, making the bidirectional screw rod 303 difficult to rotate, playing a limiting role, making the slider 304 difficult to loosen, by pushing the card plate 401, the card plate 401 gets rid of the elastic force of the contact spring 404 and slides, so that the anti-skid pad 402 is separated from the rubber sleeve 403, facilitating the free rotation of the bidirectional screw rod 303.

[0037] Specifically, Figure 2 and Figure 4 As shown, the connecting mechanism 5 includes a connecting groove 502, and a connecting groove 502 is installed at the center line of the bottom of the placement plate 201. The bottom of the placement plate 201 is engaged with the test machine 1 through the connecting groove 502. The connecting groove 502 and the top side of the test machine 1 are both hexagonal structures. The bottom side wall of the placement plate 201 is threadedly connected with a bolt 501, and one end of the bolt 501 extends to the inner side of the test machine 1. Through the opening of the connecting groove 502, the placement plate 201 and the test machine 1 are detachably connected. Through the tightening of the bolt 501, the bolt 501 is inserted into the inner side of the test machine 1, so that the placement plate 201 and the test machine 1 are firmly and stably connected.

[0038] Specifically, Figure 1 and Figure 6 As shown, the protection mechanism 6 includes a horizontal plate 602, two horizontal plates 602 are vertically connected to the top of the test machine 1, a protection plate 601 is installed on one side of the test machine 1, the top of the protection plate 601 is connected to the two horizontal plates 602, the other ends of the two horizontal plates 602 are vertically connected to two vertical plates 603, and the bottoms of the two vertical plates 603 are respectively connected to the test machine 1. The installation of the horizontal plate 602 facilitates the connection of the protection plate 601, thereby shielding and protecting the back of the test machine 1 to prevent the pot from slipping and flying out. The installation of the two vertical plates 603 facilitates the support and stability of the horizontal plate 602, and facilitates the subsequent installation of the protection rod 701.

[0039] Specifically, Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the opening and closing mechanism 7 includes a movable groove 702, and the movable groove 702 is provided on the opposite sides of the two vertical plates 603, and a plurality of equidistantly distributed protection rods 701 are provided between the two vertical plates 603, and the two ends of the plurality of protection rods 701 are respectively slidably connected to the inside of the movable groove 702, and the two ends of the plurality of protection rods 701 are respectively connected by a pull rope 703, and the top of the pull rope 703 is connected to the top of the vertical plate 603. Through the opening of the movable groove 702, the plurality of protection rods 701 can slide between the two vertical plates 603, and through the connection of the plurality of pull ropes 703, the plurality of protection rods 701 can be equidistantly arranged between the two vertical plates 603, so as to shield and protect the other side of the testing machine 1, and by pushing the protection rods 701 upward in sequence, the plurality of protection rods 701 are shrunk and piled up on the top of the vertical plate 603, so as to facilitate the storage and retrieval of the cookware.

[0040] Specifically, Figure 8 and Fig. 9 As shown, the bottom and top of the two vertical plates 603 are respectively provided with grooves 705, one end of the groove 705 extends to the inside of the movable groove 702, and the two ends of the bottommost protective rod 701 are respectively installed with protrusions 704, and the protrusions 704 are slidably connected with the inside of the protective rod 701 through compression springs 706. One end of the two protrusions 704 extends to the outside of the protective rod 701, and one end of the two protrusions 704 is a hemispherical structure. One end of the two protrusions 704 is respectively in conflict with the inside of the groove 705. By opening the groove 705, the protrusions 704 at both ends of the protective rod 701 are in contact with the concave groove. The groove 705 is in contact with the inside of the protection rod 701, so that the protection rod 701 is limited and not easy to loosen, which plays a role of shielding and protection. By pushing the protection rod 701, the protection rod 701 drives the protrusion 704 to contact the side wall of the groove 705, and the protrusion 704 is freed from the elastic force of the compression spring 706 and contracts, so that the protrusion 704 is separated from the groove 705, which facilitates the sliding of the protection rod 701. The protection rod 701 slides to a certain position on the top of the vertical plate 603, and the protrusions 704 at both ends of the protection rod 701 are in contact with the other two grooves 705, thereby achieving limitation, which is convenient for storing and taking out the cookware.

[0041] When the present invention is in use, firstly, the installation of the placement plate 201 facilitates the connection of the two support blocks 202. The installation of the two support blocks 202 supports the circular side wall of the pot, which facilitates the subsequent strength test. The two symmetrical rotating blocks 204 are connected to achieve a close fit between the rotating blocks 204 and the side wall of the pot, making the placement of the pot more stable. The installation of the rubber strip helps to increase the friction between the side wall of the pot and the side wall of the rotating block 204, making it difficult for the pot to slide after being placed, so that the detection effect is better. The placement plate 201 and the test machine 1 are detachably connected by opening the connecting groove 502. The bolt 501 is inserted into the inner side of the test machine 1 by tightening the bolt 501, so that the placement plate 201 and the test machine 1 are firmly and stably connected. The two sliders 304 are used to connect the two sliders 304. The installation is conducive to connecting the two support blocks 202. By driving the bidirectional screw rod 303, the bidirectional screw rod 303 drives the two sliders 304 to move synchronously in opposite directions under the cooperation of the thread, so that the two support blocks 202 are close to or away from each other, which is conducive to placing pots with different diameters, increasing the detection range, and making the operation more convenient. The installation of the driving disk 302 is conducive to driving and controlling the bidirectional screw rod 303, making the operation more convenient and labor-saving. The installation of multiple dust covers 301 is conducive to shielding and protecting the sliding space between the support blocks 202 to prevent debris from entering and causing the support blocks 202 to be unable to move. Through the resistance of the resistance spring 404, the card plate 401 drives the anti-skid pad 402 to contact tightly with the side wall of the rubber sleeve 403, making the bidirectional screw rod 303 not easy to The rotation plays a role of limiting, so that the slider 304 is not easy to loosen. By pushing the card plate 401, the card plate 401 gets rid of the elastic force of the resistance spring 404 and slides, so that the anti-skid pad 402 is separated from the rubber sleeve 403, which is convenient for the two-way screw rod 303 to rotate freely. Through the installation of the horizontal plate 602, it is convenient to connect the protective plate 601, so as to shield and protect the back of the test machine 1 to prevent the pot from slipping and flying out. Through the installation of the two vertical plates 603, it is convenient to support the horizontal plate 602 stably, and at the same time facilitate the installation of the subsequent protective rod 701. Through the opening of the movable groove 702, multiple protective rods 701 can slide between the two vertical plates 603. Through the connection of multiple pull ropes 703, multiple protective rods 701 can be equidistantly arranged between the two vertical plates 603, so that The other side of the test machine 1 is shielded and protected. By pushing the protection rods 701 upwards in sequence, the multiple protection rods 701 are retracted and piled up on the top of the vertical plate 603, which is convenient for storing and accessing the cookware. By opening the grooves 705, the protrusions 704 at both ends of the protection rod 701 are in conflict with the inside of the grooves 705, so that the protection rod 701 limit is not easy to loosen, which plays a role in shielding and protection. By pushing the protection rod 701, the protection rod 701 drives the protrusion 704 to conflict with the side wall of the groove 705, and the protrusion 704 is freed from the elastic force of the compression spring 706 and shrinks, so that the protrusion 704 is separated from the groove 705, which is convenient for the protection rod 701 to slide. The protection rod 701 slides to a certain position on the top of the vertical plate 603, and the protrusions 704 at both ends of the protection rod 701 conflict with the other two grooves 705.This allows for positioning and facilitates access to the cookware.
