At the same time, the positioning column 5-1 of the damping block 5 is clearance-fitted and inserted into the positioning hole II2-2 of the movable top plate 2; the front cantilever 4-2 of the torsion spring 4 contacts the lower plane of the movable top plate 2. At this time, the movable top plate 2, the connecting shaft 3, the damping block 5 and the torsion spring 4 form a whole.

[0030] The whole composed of the movable top plate 2, the connecting shaft 3, the damping block 5 and the torsion spring 4 is pressed into the fixed top plate 1, the connecting shaft 3 is installed in the shaft positioning hole Ⅰ1-2 of the fixed top plate 1 with transition fit, the rear cantilever 4-1 of the torsion spring 4 contacts the baffle 1-3 of the fixed top plate to realize the pre-compression of the torsion spring 4; the outer sides of the two damping blocks 5 are transitionally matched with the inner sides of the side plates 1-5 at both ends of the fixed top plate 1 to complete the assembly of the hidden support frame. At this time, the upper end surface of the fixed top plate 1 is flush with the upper end surface of the movable top plate 2.

[0031] The damping block 5 is made of POM material, which has good strength and self-lubrication properties. When the movable top plate 2 returns to its original state, the damping feeling is increased to prevent safety hazards caused by the rapid recovery of the movable top plate 2 due to the action of the torsion spring 4, and also makes the overall device present a sense of luxury.

[0032] like Fig.10 As shown, the fixed decorative plate 6 is processed according to the shape of the top of the main frame of the portable device, the movable hole 6-1 is processed at one end of the fixed decorative plate 6 by laser cutting according to the shape of the movable top plate 2, and the movable decorative plate 7 is processed according to the movable hole 6-1 of the decorative plate 6. The movable decorative plate 7 can be inserted into the movable hole 6-1 on the fixed decorative plate 6 with a clearance fit.

[0033] A method for using a hidden handle for railway portable equipment, which is operated as follows:

[0034] The first step is preparation: according to the structure of the main frame 8 of the portable device, several threaded holes Ⅰ1-6 are processed on the side plate of the fixed top plate 1 of the hidden handle, and the fixed top plate 1 is installed in the main frame of the portable device through the threaded holes Ⅰ1-6; the fixed decorative plate 6 is fixedly installed on the upper end of the main frame of the portable device, and the fixed top plate 1 is connected to the fixed decorative plate 6 through the threaded holes Ⅱ1-7 on the upper end surface; the movable decorative plate 7 is installed on the movable top plate 2 through the threaded holes Ⅲ2-4 on the top of the movable top plate 2, and the clearance fits in the movable hole 6-1. At this point, the fixed decorative plate 6 and the movable decorative plate 7 form a plane, and the entire hidden support frame is hidden inside the portable device, such as Fig. 9 As shown;

[0035] Step 2: Lock: Figure 4 , Figure 5 , Figure 6 As shown, when carrying a portable device, a hidden support frame needs to be used. At this time, the movable decorative plate 7 is pressed downward, and the movable top plate 2 is subjected to indirect pressure, driving the positioning column 5-1 of the damping block 5 to rotate downward around the connecting shaft 3. When the positioning protrusion 5-2 of the damping block 5 sinks into the positioning hole Ⅰ1-1 of the fixed top plate 1, the movable top plate 2 and the damping block 5 complete self-locking. At this time, the movable top plate 2 sinks into the fixed top plate 1, and the front end 1-4 of the fixed top plate 1 is lifted to lift the device;

[0036] Step 3: Recovery: Figure 7 , Figure 1 , Figure 8 As shown, after use is completed, the front end of the movable top plate 2 is pulled outward, the positioning protrusion 5-2 of the damping block 5 is disengaged from the positioning hole Ⅰ1-1 of the fixed top plate 1, and the front arm 4-2 of the torsion spring 4 lifts the lower end surface of the movable top plate 2. The movable top plate 2 and the damping block 5 rotate around the connecting shaft 3. The friction between the outer side of the damping block 5 and the inner side of the side plate 1-5 of the fixed top plate 1 realizes the damping feeling of the support frame. When the stop tongue 2-1 of the movable top plate 2 contacts the lower plane of the front end 1-4 of the fixed top plate 1, the rotation stops, and the hidden support frame returns to its initial state, and the portable device is also restored accordingly.
