Description

Technical Field

[0001] This utility model relates to the technical field of bathroom product testing equipment, and in particular to a shower stool damping testing device. Background Technology

[0002] Folding bathroom stools play a vital role in upgrading bathroom safety and making them more age-friendly, effectively improving home safety and comfort for seniors. The bathroom industry is increasingly demanding higher functionality from bathroom stools, with the damping performance of folding products being particularly crucial, directly impacting user experience and safety.

[0003] Existing folding shower stools include a seat and a mounting base for mounting the seat. The mounting base includes a load-bearing bracket installed at the bottom of the seat and a hinge structure for the load-bearing bracket to be movably mounted to the wall. In the hinge structure, a rubber ring that cooperates with the piston rod at the end of the load-bearing bracket provides damping adjustment. To ensure user experience and safety, all shower stools undergo damping performance testing before leaving the factory.

[0004] Currently, the industry commonly uses manual testing or simple mechanical devices for durability assessment. Common testing methods include: ① manual repeated opening and closing tests, relying on the operator's subjective judgment of damping changes; ② free-fall impact tests with counterweights, which can only verify instantaneous load-bearing performance; ③ motor-driven swing arm simulation tests, but lack precise angle control and stopping mechanisms. Among these, manual testing is costly and has poor repeatability (error of ±15%), counterweight tests cannot reflect long-term wear effects, and motor tests suffer from overshoot and are complex to maintain.

[0005] In view of the aforementioned technologies, the inventors believe there is a need to provide a shower bench damping testing device. Utility Model Content

[0006] To test the damping performance of a shower bench, this application provides a shower bench damping testing device.

[0007] This application provides a shower bench damping testing device, which adopts the following technical solution:

[0008] A shower bench damping testing device includes a test frame and a bidirectional drive assembly. The test frame includes a horizontal base and a contoured wall vertically mounted on the horizontal base for mounting the shower bench. The contoured wall has a set of threaded holes for mounting the shower bench damping testing device on a mounting seat for a folding shower bench. The bidirectional drive assembly includes a drive cylinder and a locking seat mounted on the piston rod of the drive cylinder. The bottom end of the drive cylinder is rotatably mounted on the horizontal base. The locking seat has a locking groove for the seat plate to engage and a locking bolt for locking the seat plate in the locking groove.

[0009] By adopting the above technical solution, when the operator uses the above-mentioned shower stool damping test device to conduct a damping test on the shower stool, firstly, the shower stool is installed on the contour wall, then the bidirectional drive component is installed on the horizontal base and connected and fixed to the shower stool through the snap-fit ​​seat of the bidirectional drive component, and finally, the drive cylinder of the bidirectional drive component is started to make the shower stool perform a 90° reciprocating rotational motion, thereby completing the damping test of the shower stool.

[0010] Optionally, the threaded hole group consists of two threaded holes arranged opposite each other, with the axes of both threaded holes being horizontally arranged.

[0011] By adopting the above technical solution, the threaded hole group is set as two threaded holes arranged opposite each other and with their axes horizontal, which makes it easier for the bath stool mounting base to be on the same horizontal line, and can better enable the bath stool to complete the damping performance test.

[0012] Optionally, the horizontal base has a mounting plate and a cylinder mounting seat for rotating the bottom end of the drive cylinder is horizontally slidably mounted on the upper surface of the mounting plate; the sliding direction of the horizontal base is perpendicular to the contour wall, and a locking structure for locking the cylinder mounting seat is also provided between the mounting plate and the cylinder mounting seat.

[0013] By adopting the above technical solution, the mounting plate on the horizontal base allows the cylinder mounting seat to slide horizontally, with the sliding direction perpendicular to the contoured wall, enabling the drive cylinder to be adjusted to fit different sizes of bath stools. The locking structure between the mounting plate and the cylinder mounting seat can lock the cylinder mounting seat in a suitable position, ensuring the stability of the drive cylinder during testing, thereby improving testing accuracy.

[0014] Optionally, the locking structure includes a mounting base plate disposed at the bottom of the cylinder mounting seat, a locking bolt threaded onto the top surface of the mounting plate, and an oblong hole formed in the mounting base plate for accommodating the locking bolt, wherein the length direction of the oblong hole is parallel to the sliding direction of the cylinder mounting seat.

[0015] By adopting the above technical solution, the specific structure of the locking structure is disclosed. This structure uses a slotted hole parallel to the sliding direction of the cylinder mounting seat in the mounting base plate, along with locking bolts on the mounting plate, as the locking mechanism. This facilitates locking the cylinder mounting seat after it has been adjusted to the appropriate position, preventing displacement during testing and ensuring the stability of the device's operation and the accuracy of the test results.

[0016] Optionally, the mounting base plate has two oblong holes, and the two oblong holes are arranged symmetrically; the locking bolts on the mounting plate correspond one-to-one with the oblong holes.

[0017] By adopting the above technical solution, two symmetrically arranged oblong holes are set on the mounting base plate, which correspond one-to-one with the locking bolts on the mounting plate. This enhances the locking effect of the cylinder mounting seat and makes the testing process more stable and accurate.

[0018] Optionally, the bottom side of the snap-fit ​​seat is provided with a locking thread hole for mounting the locking bolt.

[0019] By adopting the above technical solution, a locking thread hole for installing a locking bolt is opened on the bottom side of the snap-fit ​​seat, so that the seat plate is firmly locked in the snap-fit ​​groove of the snap-fit ​​seat by the locking bolt, ensuring that its bidirectional drive component can drive the seat plate to complete the damping performance test.

[0020] Optionally, the number of locking threaded holes in the snap-fit ​​seat is two, and the two locking threaded holes are arranged symmetrically on the left and right.

[0021] By adopting the above technical solution and arranging two symmetrical locking threaded holes to install locking bolts, the base plate can be more stably locked in the snap-fit ​​groove, enhancing the locking effect of the base plate and improving the stability of the base plate installation during the test.

[0022] Optionally, the contoured wall has a mounting plate for mounting a folding bath stool, and both threaded holes are formed in the mounting plate.

[0023] By adopting the above technical solution, the fixing plate provides an installation position for the mounting base of the folding bath stool. The two threaded holes opened in the fixing plate can facilitate the installation of the mounting base on the contour wall, ensuring the stable installation of the bath stool for damping testing.

[0024] Optionally, the contoured wall includes a fixed outer frame, a first fixing plate that slides along the width direction and is installed inside the fixed outer frame, a second fixing plate that slides along the width direction and is installed inside the fixed outer frame, and a driving mechanism installed on the fixed outer frame and driving the first fixing plate and the second fixing plate to slide relative to each other; the first fixing plate has the threaded hole; the second fixing plate has the threaded hole.

[0025] By adopting the above technical solution, the specific structure of the contour-following wall is disclosed. This structure uses a driving mechanism to allow the first and second fixed plates to slide relative to each other, thereby adjusting their distance and accommodating the installation of shower stools of different sizes, thus improving the device's versatility. Furthermore, both the first and second fixed plates are provided with threaded holes, which can be fitted with mounting bolts to install the first and second fixed plates onto the fixed outer frame.

[0026] Optionally, the drive mechanism includes a first lead screw horizontally mounted on the fixed outer frame, a first nut mounted on the first fixed plate, a second nut mounted on the second fixed plate, and a drive handle mounted on the end of the first lead screw; the first lead screw has a first drive section and a second drive section arranged opposite to each other; the first nut cooperates with the first drive section, and the second nut cooperates with the second drive section.

[0027] By adopting the above technical solution, the specific structure of the drive mechanism is disclosed. This structure, through the cooperation of the first lead screw with the first nut and the second nut, and the drive handle provided at the end of the first lead screw, enables the relative sliding of the first fixed plate and the second fixed plate, thereby adapting to different specifications of bath stools and improving the versatility of the testing device.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0039] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail below.

[0040] Example 1:

[0041] This application discloses a shower stool damping testing device for detecting the flipping damping of a folding shower stool 3. (Refer to...) Figure 1 and Figure 2 The folding bath stool 3 includes a seat plate 31 and a mounting base 32 for rotatably mounting the seat plate 31. The seat plate 31 has a rotating part 311 for rotatably engaging with the mounting base 32, and the mounting base 32 has a rotating groove 321 for rotatably arranging the rotating part 311. The rotating part 311 is mounted in the rotating groove 321 via a rotating shaft 33. Damping components 34 are sleeved on the rotating shaft 33 and arranged on both sides of the rotating part 311. The damping components 34 have shoulder structures 341 arranged between the sidewalls of the rotating part 311 and the rotating groove 321, providing damping for the rotation of the seat plate 31. In this embodiment, the durability test performed by the bath stool damping test device tests the durability of the damping components 34 in the folding bath stool 3. Since some features of the bath stool damping test device reference the structure of the folding bath stool 3, the structure of the folding bath stool 3 can be referred to accordingly. Figure 1 and Figure 2 This will not be cited separately below.

[0042] Reference Figure 3 and Figure 4 A shower bench damping testing device includes a test frame 1, a bidirectional drive assembly 2, and a detection assembly mounted on the top of the test frame 1.

[0043] Reference Figure 4 The test frame 1 includes a horizontal base 11 and a contoured wall 12 vertically mounted on the horizontal base 11 for mounting a folding bath stool. The contoured wall 12 has a fixing plate 121 for mounting a mounting base 32 of a folding bath stool 3. The fixing plate 121 has a set of threaded holes 1211 for mounting the mounting base 32 of the folding bath stool 3. The set of threaded holes 1211 consists of two threaded holes 1211 arranged opposite each other. The axes of the two threaded holes 1211 are both horizontally arranged. By setting the set of threaded holes 1211 as two threaded holes 1211 arranged opposite each other with horizontal axes, the mounting base 32 of the bath stool is placed on the same horizontal line, allowing for better completion of damping performance testing of the bath stool.

[0044] Reference Figure 4 The horizontal base 11 has a mounting plate 111 and a cylinder mounting seat 112 for rotating the bottom end of the bidirectional drive assembly 2 is horizontally slidably mounted on its upper surface. The sliding direction of the horizontal base 11 is perpendicular to the contour wall 12. A locking structure for locking the cylinder mounting seat 112 is also provided between the mounting plate 111 and the cylinder mounting seat.

[0045] Reference Figure 4 The locking structure includes a mounting base plate 1121 disposed at the bottom of the cylinder mounting seat 112, a locking bolt 113 threaded onto the top surface of the mounting base plate 1121, and an oblong hole 1122 formed in the mounting base plate 1121 for accommodating the locking bolt 113. The length direction of the oblong hole 1122 is parallel to the sliding direction of the cylinder mounting seat 112. There are two oblong holes 1122 on the mounting base plate 1121, and the two oblong holes 1122 are arranged symmetrically. The locking bolt 113 on the mounting plate 111 corresponds one-to-one with the oblong hole 1122. By forming an oblong hole 1122 parallel to the sliding direction of the cylinder mounting seat 112 in the mounting base plate 1121 and cooperating with the locking bolt 113 on the mounting plate 111 as a locking structure, it is convenient to lock the cylinder mounting seat 112 after it is adjusted to a suitable position, preventing displacement during the test and ensuring the stability of the device operation and the accuracy of the test results.

[0046] Reference Figure 4 and Figure 5The bidirectional drive assembly 2 includes a drive cylinder 21 and a locking seat 22 mounted on the piston rod of the drive cylinder 21. The bottom end of the drive cylinder 21 is rotatably mounted on a cylinder mounting base 112. The locking seat 22 has a locking groove 222 for the seat plate 31 to engage and a locking bolt 223 for locking the seat plate 31 within the locking groove 222. A locking threaded hole 221 for mounting the locking bolt 223 is provided on the bottom side of the locking seat 22. The locking seat 22 has two locking threaded holes 221, which are symmetrically arranged left and right. By arranging the two locking threaded holes 221 on the bottom side of the locking seat 22, the locking bolt 223 will not damage the front surface of the seat plate 31 when locking it.

[0047] Reference Figure 3 and Figure 4 The detection components include an electronic counter mounted on the top of the contour wall 12, a PLC controller mounted on the back of the contour wall 12, and a digital display screen connected to the PLC controller. When the base plate 31 moves to be parallel with the contour wall 12, the base plate 31 obtains a sensing signal by colliding with the end of the electronic counter. The PLC controller counts the signals based on the sensing signals and displays the counted results on the digital display screen.

[0048] The implementation principle of the shower stool damping test device in this application embodiment is as follows: A shower stool damping test device includes a test frame 1 and a bidirectional drive component 2. The shower stool is first installed on the contour wall 12, and then the bidirectional drive component 2 is fixed on the horizontal base 11. The shower stool is then connected and fixed by the snap-fit ​​seat 22 of the bidirectional drive component 2. Finally, the drive cylinder 21 of the bidirectional drive component 2 is started to drive the shower stool to perform a 90° reciprocating rotational motion to complete the damping test of the shower stool.

[0049] Example 2:

[0050] Compared with Example 1, this embodiment is identical to the structure of the shower bench damping test device in Example 1, except for the structure of the contour wall 12.

[0051] Reference Figure 6 In this embodiment, the contoured wall 12 includes a fixed outer frame 122, a first fixing plate 123 slidably mounted inside the fixed outer frame 122 along the width direction, a second fixing plate 124 slidably mounted inside the fixed outer frame 122 along the width direction, and a driving mechanism 125 mounted on the fixed outer frame 122 and driving the first fixing plate 123 and the second fixing plate 124 to slide relative to each other. Both the first fixing plate 123 and the second fixing plate 124 have threaded holes 1211 for use with bolts to install the bath stool onto the contoured wall 12.

[0052] Reference Figure 1 and Figure 6The drive mechanism 125 includes a first lead screw 1251 horizontally mounted on the fixed outer frame 122, a first nut 1252 mounted on the first fixed plate 123, a second nut 1253 mounted on the second fixed plate 124, and a drive handle 1254 mounted on the end of the first lead screw 1251. The first lead screw 1251 has a first drive section 1255 and a second drive section 1256 arranged opposite to each other. The first nut 1252 cooperates with the first drive section 1255, and the second nut 1253 cooperates with the second drive section 1256. When the drive handle 1254 is rotated, the first lead screw 1251 will rotate. Since the first nut 1252 and the second nut 1253 cooperate with different drive sections, the first fixed plate 123 and the second fixed plate 124 will slide relative to each other, thereby adjusting the distance between the two threaded holes 1211 to adapt to the installation requirements of folding bath stools 3 of different specifications.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
