[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] As attached Figures 1 to 6 The folder with built-in elastic member comprises a first folding seat 1, a second folding seat 2 and a locking switch 3. A fastening groove 4 is provided in the first folding seat 1. The fastening groove 4 is shown in the attached Figure 2 A fastening block 5 and a conducting block 6 are movably arranged in the second folding seat 2. The fastening block 5 and the conducting block 6 are shown in the attached Figure 4 as shown in .

[0023] As attached Figure 1 As shown in the figure, when the first folding seat 1 and the second folding seat 2 are relatively connected, the locking switch 3 in the closed state can squeeze the fastening block 5 through the conductive block 6, and press the fastening block 5 into the fastening groove 4, thereby locking the first folding seat 1 and the second folding seat 2, so that the first folding seat 1 and the second folding seat 2 are relatively fixed.

[0024] An elastic pre-stressing member 7 is provided between the conductive block 6 and the fastening block 5. When the first folding seat 1 is relatively connected to the second folding seat 2, and the locking switch 3 is in the open state, the elastic force of the elastic pre-stressing member 7 still pre-stresses the fastening block 5 into the fastening groove 4. A convex button 18 is provided on the fastening block 5 on the side away from the conductive block 6, and the convex button 18 extends out of the second folding seat 2 from the through hole on the second folding seat 2. When the locking switch 3 is in the open state, pressing the convex button 18 can compress the elastic pre-stressing member 7, forming an escape space in the second folding seat 2, so that the fastening block 5 can move toward the escape space, thereby disengaging from the fastening groove 4. If the elastic pre-stressing member 7 is not provided, then when the locking switch 3 is in the open state, the conductive block 6 and the fastening block 5 will separate from each other, and the fastening block 5 and the conductive block 6 are easy to move and collide in the folding seat, making noise, affecting the user's experience. Therefore, it is necessary to provide an elastic pre-stressing member 7 between the conducting block 6 and the fastening block 5 so that when the locking switch 3 is turned on, the elastic pre-stressing member 7 can prevent the conducting block 6 and the fastening block 5 from colliding and making noise.

[0025] The elastic pre-pressed member 7 in the existing folding seat is generally a separate telescopic spring, which is easy to escape during the assembly process and is inconvenient to install. In the present utility model, the elastic pre-pressed member 7 is fixedly connected to the conductive block 6, so that the elastic pre-pressed member 7 and the conductive block 6 are combined into a pre-assembled module. During the assembly process, the elastic pre-pressed member 7 is first fixedly connected to the conductive block 6, and then the elastic pre-pressed member 7 can be assembled together when the conductive block 6 is assembled, thereby optimizing the assembly process of the folding seat.

[0026] As attached Figure 5As shown in , the elastic preload 7 includes two elastic strips 8 at a certain angle, one end of the elastic strip 8 abuts against the fastening block 5, and the angle between the two elastic strips 8 is changed when the elastic preload 7 is elastically deformed. The end of the elastic strip 8 abutting against the fastening block 5 is curled into an arc, and when the angle between the two elastic strips 8 changes, the arc end of the elastic strip 8 can still maintain contact with the fastening block 5. The two elastic strips 8 are connected as a whole, and the two elastic strips 8 are combined into a V shape, and the connection between the two elastic strips 8 is fixed to the conduction block 6 by a fixing bolt 9. The conduction block 6 is provided with a screw hole that matches the fixing bolt 9. The fixing bolt 9 can be used to conveniently fix the elastic preload 7 to the conduction block 6, and the assembly is convenient.

[0027] As attached Figure 5 and 6 As shown in the figure, a tightening piece 11 is provided on the fastening block 5. When the convex button 18 is pressed, the fastening block 5 moves toward the conductive block 6. At this time, the fastening block 5 presses against the conductive block 6 through the tightening piece 11. The tightening piece 11 can limit the minimum distance between the fastening block 5 and the conductive block 6 to avoid damage to the elastic pre-stressing piece 7 due to excessive deformation.

[0028] The fastening block 5 is provided with an adjustment screw hole 10, and the jacking piece 11 is provided with a stud section 12, and the stud section 12 of the jacking piece 11 is threadedly connected in the adjustment screw hole 10. When the jacking piece 11 rotates in the adjustment screw hole 10, the minimum distance between the fastening block 5 and the conductive block 6 is changed. Figure 1 As shown in the figure, when the first folding seat 1 is relatively connected to the second folding seat 2 and the locking switch 3 is in the closed state, the pressing member 11 is correspondingly pressed against the conductive block 6, thereby pressing the fastening block 5 tightly against the fastening groove 4, achieving a better locking effect.

[0029] The fastening block 5 is also provided with a fixing screw hole 19 , which is perpendicular to the adjusting screw hole 10 . A fixing bolt 20 is arranged in the fixing screw hole 19 , and the fixing bolt 20 can prevent the stud section 12 from rotating in the adjusting screw hole 10 .

[0030] The top fastener 11 is provided with a top cap 13 at one end facing the conductive block 6, and the conductive block 6 has a top groove opposite to the top cap 13. A nut section 14 is also provided between the top cap 13 and the stud section 12, and the top fastener 11 can be conveniently screwed through the nut section 14, so as to adjust the minimum distance between the fastening block 5 and the conductive block 6.

[0031] The locking switch 3 is a wrench, and a rotating shaft 15 is arranged on the second folding seat 2. An eccentric shaft 16 is arranged at one end of the wrench. The eccentric shaft 16 is hollow and sleeved on the rotating shaft 15. Figure 3As shown in , when the free end of the wrench is upward, the locking switch 3 is correspondingly in the closed state; when the free end of the wrench is downward, the locking switch 3 is correspondingly in the open state. The conductive block 6 fits with the eccentric shaft 16, and in the process of gradually closing the locking switch 3, that is, in the process of the wrench being pulled from bottom to top, the eccentric shaft 16 rotates around the rotating shaft 15, pushing the conductive block 6 to squeeze the fastening block 5 until the pressing member 11 presses on the conductive block 6, thereby locking the first folding seat 1 and the second folding seat 2.

[0032] As attached Figure 6 As shown in , the side of the conduction block 6 facing the locking switch 3 is provided with an arc groove 17 , and the eccentric shaft 16 is inserted into the arc groove 17 , so that the conduction block 6 fits the eccentric shaft 16 .

[0033] Reference Figure 5 and 6 As shown in the figure, the conduction block 6 is in an inverted L shape, and is composed of an upper horizontal plate portion and a lower vertical plate portion. A sliding groove is provided below the horizontal plate portion, and a sliding block is provided at the upper end of the fastening block 5, so that the conduction block 6 and the fastening block 5 can slide and cooperate. The elastic pre-compression member 7 is correspondingly provided on the side of the vertical plate portion facing the fastening block 5.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
