Description

Technical Field

[0001] The invention belongs to the technical field of cooker detection, and in particular relates to a pressure resistance detection device and a detection method for outdoor cookers. Background Art

[0002] Outdoor cookers generally have certain requirements for overall physical properties, so they are usually subjected to compression tests before leaving the factory. Since there are no clear standards for this test item, the testing methods of each manufacturer are different. Most of them use a hydraulic press to directly extrude the surface of the cooker to obtain feedback from the overall shape.

[0003] This detection method is too rough. Referring to the use scenario of outdoor cookers, the cookers are often clamped and stressed in the circumference, so only using direct positive pressure cannot provide a good reference for their performance. At the same time, existing cookers usually have a new material coating on the inner surface, such as a non-stick coating. The existing methods cannot detect whether the coating is cracked under pressure. Summary of the invention

[0004] The object of the present invention is to provide a pressure resistance detection device and a detection method for outdoor cookers to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device and method for detecting the pressure resistance of outdoor cooking utensils, comprising an internal support mechanism and a pressurizing mechanism;

[0006] The inner support mechanism is arranged on a rotating seat, a slide rail is arranged inside the rotating seat, an inner support head is hingedly connected to the bottom of the slide rail by a parallelogram connecting rod structure, a locking connecting rod is hingedly connected to the upper end of the inner support head, a slider is arranged at the end of the locking connecting rod, the slider is slidably connected in the slide groove of the slide rail, and is connected to a driving source to realize up and down sliding, so as to control the opening and contraction of the inner support head;

[0007] The pressurizing mechanism includes a central column, which is a hollow structure. The internal cavity of the central column serves as a detection cavity. A rotating ring is rotatably connected to the outside of the central column. The rotating ring is configured to rotate along the axis of the central column. A clamping portion is provided at the end of the pressurizing mechanism. The clamping portion includes a first ring buckle provided on the rotating ring and a second ring buckle provided on the central column. The second ring buckle is movably connected to the central column. A clamping column is inserted in the first ring buckle and the second ring buckle. The clamping column is fixed to the first ring buckle, and the clamping column is slidably connected to the second ring buckle. There are four groups of combinations of the clamping column, the first ring buckle and the second ring buckle, and the clamping columns are arranged in double rows vertically and horizontally.

[0008] It should be noted in the scheme that two groups of inner support heads are provided, namely the first inner support head and the second inner support head, wherein the outer edge of the second inner support head is provided with a scraper for scraping off the coating on the inner surface of the cookware, and the outer edge of the first inner support head is provided with a conductive sheet, which is connected to a power supply and an electric meter.

[0009] It is further worth noting that the slider of the locking connecting rod on the first inner support head is connected to the first driving rod, and the slider of the locking connecting rod on the second inner support head is connected to the second driving rod. The first driving rod and the second driving rod are both separately connected to the driving source to achieve independent drive.

[0010] It should be further explained that the second driving rod is embedded in the first driving rod and is slidably connected to the first driving rod. The second driving rod is also connected to an inner sliding rod, and the bottom of the inner sliding rod is connected to an internal pressure head. The slide rail is a hollow structure, and the inner sliding rod is slidably connected in the inner cavity of the slide rail.

[0011] As a preferred embodiment, two rotating rings are provided, which are arranged on both sides of the central column, and both rotating rings are provided with a clamping part, which is detachably connected to the rotating ring.

[0012] As a preferred embodiment, a support column and a cylinder are provided on the circumferential side of the rotating ring, and the output end of the cylinder is hinged to the support column to realize driving.

[0013] The present invention also provides a method for detecting the pressure resistance of outdoor cookers, which is characterized by: using the above-mentioned device for detecting the pressure resistance of outdoor cookers, comprising the following steps:

[0014] Apply conductive liquid to the inner surface of the cookware to be tested or directly fill it with conductive liquid;

[0015] Place the cookware to be tested into the central column so that the clamping column contacts the peripheral surface of the cookware to be tested;

[0016] The inner support mechanism is transferred to the cookware to be tested. First, the second driving rod is driven by the driving source so that the second inner support head abuts against the inner surface of the cookware to be tested. Then, the inner support mechanism is controlled to rotate as a whole. The scraper of the second inner support head scrapes a circle of the coating on the inner surface of the cookware to be tested. Then, the first driving rod is driven so that the first inner support head is pressed against the inner surface of the cookware to be tested. Moreover, the conductive sheet of the first inner support head is connected to the position of the scraped coating on the inner surface of the cookware to be tested. At the same time, the inner pressure head abuts against the bottom of the cookware to be tested.

[0017] The rotating ring is driven to rotate, and the clamping column squeezes the cookware to be tested. When the inner surface of the cookware to be tested is pressed and the coating bursts, the conductive liquid contacts the inner material of the cookware to be tested, and the circuit resistance changes, so that the test item is fed back on the electric meter.

[0018] Compared with the prior art, the present invention provides an outdoor cooker compression test device and method, which realizes compression test of circumferential force on cookers and compression test of new material coatings through a pressurizing mechanism and an inner support mechanism.

[0024] See also Figure 1-5 , The present invention provides a pressure resistance detection device and detection method for outdoor cookers, 1. It includes an internal support mechanism 1 and a pressure mechanism 2;

[0025] Reference Figure 1 as well as Figure 3 , Figure 4 As shown: the inner support mechanism 1 is arranged on the rotating seat 10, and a slide rail 13 is arranged in the rotating seat 10. The bottom of the slide rail 13 is hinged with an inner support head 15 using a parallelogram connecting rod structure 16. The upper end of the inner support head 15 is hinged with a locking connecting rod 14. The end of the locking connecting rod 14 is hinged with a slider. The slider is slidably connected in the slide groove of the slide rail 13 and is connected to a driving source 24 to achieve up and down sliding, so as to control the expansion and contraction of the inner support head 15.

[0026] Reference Figure 4 As shown, the inner support head 15 is provided with two groups, namely the first inner support head 151 and the second inner support head 152, wherein the outer edge of the second inner support head 152 is provided with a scraper for scraping off the coating on the inner surface of the cooker, and the outer edge of the first inner support head 151 is provided with a conductive sheet, which is connected to a power supply and an electric meter. Specifically, since the first inner support head 151 is provided with multiple groups in a ring shape, conductive sheets can be provided on two of the groups, and a redundant design can also be performed. The electric meter can be an ohmmeter.

[0027] Continue to refer to Figure 3As shown, the slider of the locking connecting rod 14 on the first inner support head 151 is connected to the first driving rod 11, and the slider of the locking connecting rod 14 on the second inner support head 152 is connected to the second driving rod 12. The first driving rod 11 and the second driving rod 12 are individually connected to the driving source 24 to achieve independent driving. The driving source 24 adopts a structure such as a cylinder or a screw. The advantage of using two sets of driving sources to drive independently is that the functions of the two sets of inner support heads are different. The first inner support head 151 is used to scrape off the coating, so the first inner support head does not need to be too tightly abutted against the inner surface of the cooker. Too tight will easily drive the cooker to rotate together, while the second inner support head 152 needs a certain amount of pressure on the cooker, so a stronger abutting force is required. The independent control method is more flexible and has better fault tolerance.

[0028] The second driving rod 12 is embedded in the first driving rod 11 and is slidably connected to the first driving rod 11. The second driving rod 12 is also connected to an inner sliding rod, and an inner pressure head 17 is connected to the bottom of the inner sliding rod. The slide rail 13 is a hollow structure, and the inner sliding rod is slidably connected in the inner cavity of the slide rail. The overall structural arrangement is more compact and scientific. The height of the inner pressure head 17 can be adjusted on the inner sliding rod, such as by using a threaded connection, or the inner pressure head 17 can be set to an elastic structure, such as connecting a spring to match the size of the cooker, to ensure that when the inner support head is pressed tightly, the inner pressure head 17 is also pressed tightly against the bottom of the cooker at the same time.

[0029] The pressurizing mechanism 2 includes a central column 22, which is a hollow structure. The internal cavity of the central column 22 serves as a detection cavity. A rotating ring 23 is rotatably connected to the outside of the central column 22. The rotating ring 23 is configured to rotate along the axis of the central column 22. A clamping portion 21 is provided at the end of the pressurizing mechanism 2. The clamping portion 21 includes a first ring buckle 27 provided on the rotating ring 23 and a second ring buckle 25 provided on the central column 22. The second ring buckle 25 on the central column 22 is movably hinged to the central column 22. A clamping column 26 is inserted into the first ring buckle 27 and the second ring buckle 25. The clamping column 26 is fixed to the first ring buckle 27, and the clamping column 26 is slidably connected to the second ring buckle 25. There are four groups of combinations of the clamping column 26, the first ring buckle 27 and the second ring buckle 25, and the clamping column 26 is arranged in double rows vertically and horizontally.

[0030] When the rotating ring 23 rotates forward, it pushes the clamping posts 26 to be centered and close to each other, and when it rotates reversely, it pushes the clamping posts 26 to be centered and separated, thereby achieving the function of clamping and applying force to the peripheral surface of the cookware.

[0031] Reference Figure 3As shown, in another preferred embodiment, two rotating rings 23 are provided, which are arranged on both sides of the central column 22, and both rotating rings 23 are provided with a clamping portion 21, and the clamping portion 21 is detachably connected to the rotating ring 23. The peripheral side of the rotating ring 23 is provided with a support column and a cylinder, and the support column connects the two rotating rings 23, and the output end of the cylinder is hinged with the support column to realize driving. In some usage scenarios, only the peripheral surface of the cooker needs to be extruded, and the internal support mechanism is not required. Figure 3 The two groups of pressure mechanisms shown are complete. After use, the clamping column 26 on one side is disassembled and can also be used in conjunction with the inner support mechanism.

[0032] The specific testing method is: there are two testing methods, one is to simply pressurize the circumference of the cooker to feedback its pressure resistance, which can be used Figure 1 or Figure 3 The mechanism is used to extend the cooking utensils, such as pots, buckets and other products, into the pressurizing mechanism, and the rotating ring 23 is rotated to squeeze them, and the pressure resistance is judged by the size of the force applied and the deformation.

[0033] Another way is to test the coating material, including the following steps:

[0034] The inner surface of the cookware to be tested is coated with conductive liquid or directly filled with conductive liquid. It is worth mentioning that the conductive liquid coated or filled cannot cover the height of the position where the inner support head of the inner support mechanism 1 is to abut;

[0035] Place the cookware to be tested into the central column 22 so that the clamping column 26 contacts the peripheral surface of the cookware to be tested;

[0036] The inner support mechanism 1 is transferred to the cookware to be tested. First, the second driving rod 12 is driven by the driving source so that the second inner support head 152 abuts against the inner surface of the cookware to be tested (generally near the upper edge, not in direct contact with the conductive liquid). Then, the inner support mechanism 1 is controlled to rotate as a whole. The scraper of the second inner support head 152 scrapes a circle of the coating on the inner surface of the cookware to be tested to expose the internal conductive material layer, which is a non-conductive layer such as a ceramic coating or a Teflon coating. Then, the first driving rod 11 is driven so that the first inner support head 151 is pressed against the inner surface of the cookware to be tested, and the conductive sheet of the first inner support head 151 is connected to the position on the inner surface of the cookware to be tested where the coating is scraped off. At the same time, the inner pressure head 17 abuts against the bottom of the cookware to be tested.

[0037] The rotating ring 23 is driven to rotate, and the clamping column 26 squeezes the cookware to be tested. The pressurizing mechanism can also synchronously apply an internal supporting force to assist the force. When the inner surface of the cookware to be tested is pressed and the coating bursts, the conductive liquid contacts the inner conductive material of the cookware to be tested, and the circuit resistance changes, so that the test item is fed back on the electric meter.
