Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example 1:

[0033] Reference Figures 1 to 7 This is the first embodiment of the present invention, which provides a multi-station handrail testing device, including a base plate 100 and a frame 200 mounted on top of it.

[0034] The base plate 100 supports the frame 200, and the frame 200 is used to support the parts required in the testing operation.

[0035] It also includes a test mechanism 300, of which there are four test mechanisms 300. The test mechanisms 300 are located on the outside of the frame 200. Each test mechanism 300 includes a docking ring and a docking post, which are coaxially arranged. The docking ring is fitted to the outside of the docking post.

[0036] When performing routine testing, a vertical rapid docking method can be adopted between the docking ring and the docking column to reduce the difficulty of docking, increase the docking speed, and complete the routine stress testing of the handrail.

[0037] It should be noted that the docking ring and the docking post are respectively provided with matching notches and protrusions.

[0038] Example 2:

[0039] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, it also includes a testing mechanism 300, of which there are four. The testing mechanism 300 is set on the outside of the frame 200 and is used to perform different testing operations on seats of different specifications. The testing mechanism 300 includes a loading pad 310 and a sleeve 320. The loading pad 310 is provided with a ball head 311 inside the sleeve 320, and the ball head 311 can move inside the sleeve 320.

[0041] When it is necessary to adjust the force angle of the handrail, the user can directly move the loading pad 310 to make the ball head 311 move within the sleeve 320. When it moves to the required angle, the ball head 311 is locked and fixed.

[0042] The above-mentioned adjustment and locking method also facilitates the quick installation of the loading pad 310. When disassembly is required, the locking and fixing of the ball head 311 is released, and then the ball head 311 can be pulled out along the sleeve 320.

[0043] It should be noted that the testing mechanism 300 has four points distributed. Depending on the specifications and type of the seating, two corresponding points can be used in combination. The specific combination method can be selected according to actual needs.

[0044] The loading pad 310 comes in a variety of shapes and sizes, allowing for selection based on different types of handrails.

[0045] Two sliding frames are installed on the outside of the frame 200, and two sliding blocks that dock with the sliding frames are provided on the base plate 100.

[0046] like Figure 1 As shown, by using the sliding frame, the user can push the frame 200 to adjust its movement in the front and back directions;

[0047] It should be noted that there are corresponding sliders between the sliding bracket and the sliding base.

[0048] Specifically, the frame 200 is equipped with a vertically adjustable crossbeam 210, and a test cylinder 220 is installed between the crossbeam 210 and the sleeve 320.

[0049] The crossbeam 210 is used to support the test cylinder 220.

[0050] Specifically, four sleeve frames 211 are slidably sleeved on the outer side of the crossbeam 210, and one end of the test cylinder 220 is hinged to the inside of the sleeve frame 211.

[0051] Using the frame 211, when the pressure angle of the test cylinder 220 needs to be adjusted, the user can directly move the test cylinder 220 and lock it in place when it moves to the appropriate position.

[0052] It should be noted that a set of drive wheels is provided between the sleeve 211 and the crossbeam 210 to ensure smooth movement, and an arc-shaped groove is provided on the sleeve 211 to match the angle adjustment of the test cylinder 220.

[0053] Specifically, two adjusting cylinders are installed inside the frame 200, with one end of each adjusting cylinder attached to the outside of the crossbeam 210.

[0054] The adjustable cylinder can drive the crossbeam 210 to move vertically, thereby changing the distance between the loading pad 310 and the handrail;

[0055] It should be noted that the outer side of the crossbeam 210 is fitted with a retractable protective pad, which is a corrugated pipe type structure design, and the protective pad shields and protects the adjusting cylinder.

[0056] Specifically, a semi-circular groove is provided inside the sleeve 320, and a flared groove communicating with the semi-circular groove is provided at one end of the sleeve 320.

[0057] The semi-circular groove design allows it to be adapted to the ball head 311. Combined with the flared groove design, it facilitates the flexible movement of the vertical rod on the ball head 311, reducing the occurrence of jamming while allowing for the adjustment of the loading pad 310 angle.

[0058] Example 3:

[0059] Reference Figures 1-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0060] Specifically, a magnet 321, which is magnetically connected to the ball head 311, is installed in the semi-circular groove. The magnet 321 is in the shape of a semi-circular shell.

[0061] The semi-circular shell-shaped magnet 321 is attracted to the ball head 311 after it has moved into place, thus pre-fixing the ball head 311, reducing installation difficulty and improving installation efficiency.

[0062] It should be noted that the outer side of the ball head 311 is provided with anti-slip texture, which can reduce the occurrence of accidental shaking when locking and fixing it later.

[0063] Specifically, a set of locking handles 230 is provided on the outside of the frame 200, and the set of locking handles 230 is respectively installed on the sliding frame, the sleeve frame 211 and the sleeve 320.

[0064] After adjusting the front and rear positions of the frame 200, the horizontal position of the sleeve 211, the angle of the test cylinder 220, and the angle of the ball head 311, the corresponding locking handles 230 at the corresponding points can be used to complete the corresponding locking and fixing.

[0065] Specifically, the locking handle 230 includes a grip 231, a lead screw 232 and a locking block 233. One end of the lead screw 232 extends into the interior of the grip 231, and the other end of the lead screw 232 is threaded into the interior of the locking block 233.

[0066] When locking is required, the user can rotate the handle 231 to move the lead screw 232 accordingly. Then, the lead screw 232 drives the locking block 233 to move. The locking block 233 is limited by its own position and moves in a straight line to apply pressure and fit with the corresponding area to complete the locking process.

[0067] It should be noted that a sliding groove is provided in the sliding frame, sleeve 211 and sleeve 320 to limit the locking block 233 without affecting its sliding, thereby completing the above-mentioned limiting operation.

[0068] Example 4:

[0069] Reference Figures 6-7 This is the fourth embodiment of the present invention, which is based on the third embodiment described above.

[0070] In the above embodiments, the docking ring and the docking post can also be docked using a locking handle 230, but the connection area does not have a locking block 233 design. A docking surface is provided on the docking post, and a threaded groove matching the lead screw 232 is provided on the docking surface.

[0071] Furthermore, the docking ring and the loading pad 310 are detachably connected.

[0072] Specifically, a set of positioning holes are provided on the top of the base plate 100, and a set of limiting components are installed on the base plate 100 through the positioning holes.

[0073] Users can install the limiting components onto the corresponding positioning holes according to the seat's condition to limit the seat's movement and reduce unexpected shaking during subsequent testing.

[0074] It should be noted that the limiting component includes several locking plates and several pairs of limiting brackets that abut against the outer side of the seat. The locking plates are provided with collars that support and limit the seat casters.

[0075] The installation positions of the card plate and the limit bracket can be selected according to the seat specifications, and the height of the limit bracket itself is adjustable. The adjustment point is locked using the corresponding bolts.

[0076] In use, the limiting frame is installed on the base plate 100 according to the seat condition, and then the seat is placed on the limiting component. The user manually fine-tunes the limiting component to complete the limiting treatment of the seat. Then, according to the position and specifications of the seat, the positions of the frame 200, crossbeam 210 and test cylinder 220 are adjusted. Subsequently, the test cylinder 220 can be driven to drive the loading pad 310 to perform the test operation. During the test, the user can change the position of the ball head 311 and the test cylinder 220 multiple times so that the loading pad 310 and the test cylinder 220 form different angles. The pressure direction of the test cylinder 220 changes accordingly with the force angle on the armrest, so as to perform diversified test operations and obtain different test results.

[0077] During seat replacement testing, the user can drive the locking handle 230 on the sleeve 320 to release the limit on the ball head 311 and complete the quick replacement of the loading pad 310.

[0078] It should be noted that a control box is installed on the outside of the rack 200 to control the electrical components inside the entire device. This type of control technology is a mature existing technology and will not be described in detail here.

[0079] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
