Fig. 2A is a perspective view of the door handle device 3 of the present application applied to a fireproof door panel 2. As shown in fig. 2A, the door panel 2 is used as an escape door, a lock box device 2A exposed from a side of the door panel 2 is disposed in an interlayer of the escape door, and the handle device 3 is transversely disposed at the center of the door panel 2 to actuate a lock bolt 21 in the lock box device 2A, so that the door panel 2 is in a locked state or an unlocked state.

In the present embodiment, the door surface of the door panel 2 is rectangular, so that the moving direction of the door panel 2 is defined as the front and rear direction (as indicated by arrow X), the direction along the short side of the door panel 2 is defined as the left and right direction (as indicated by arrow Y), and the height direction along the door panel 2 is defined as the up and down direction (as indicated by arrow Z). It should be understood that the orientations of the arrow directions X, Y, Z are used for explaining the configuration of the present embodiment, and are not particularly limited.

In addition, one side of the lock box device 2a is linked with the door handle device 3, and the other side is linked with a rotating handle 25, as shown in fig. 2B.

As shown in fig. 3A to 3E, the door handle device 3 includes: a carrying component 3a, a shell component 3b, an acting component 3c and a driving component 3 d.

The bearing component 3a includes a seat 31 and a cover 30 disposed on the seat 31, and a seat cover 31a is disposed on the seat 31, so that the cover 30 covers the seat cover 31 a.

In the embodiment, the seat 31 is a plate fixed on the door panel 2, and the seat 31 and the cover 30 form an accommodating space for accommodating the driving component 3 d.

In addition, the cover 30 is substantially in the shape of a trapezoidal shell, the bottom end of which is fixedly connected to the seat 31, and the right side of which is provided with an opening-shaped mounting portion 300 for connecting (e.g., sleeving) the housing component 3 b.

In addition, the seat cover 31a is arched, and defines a channel (i.e., arched position) in the accommodating space with the seat body 31 to limit the position of the driving component 3d (as shown in fig. 3A) so as to facilitate installation of the driving component 3 d.

In addition, the seat body 31 has an adjusting hole 310, and the seat cover 31a has a supporting point hole 311.

The housing assembly 3b includes a base 33 connected to the mounting portion 300 and a pressing member 32 disposed on the base 33, such that the base 33 and the pressing member 32 serve as a housing of the door handle device 3.

In the embodiment, the base 33 is a groove-shaped strip frame, which is disposed on the door panel 2 and is used for accommodating the acting component 3c and a part of the driving component 3 d. For example, the base 33 has an insertion portion 330 at the edge of the left side wall for inserting into the mounting portion 300 to be engaged with the outer side of the seat cover 31 a.

In addition, the pressing member 32 is a cross bar type handle, which is an integrally formed reinforced structure, and is movably accommodated in the base 33, and the left and right sides of the pressing member 32 have inclined

sides

32a,32b with the same inclination direction, so that the side surface of the pressing member 32 is in a parallelogram shape. For example, the pressing member 32 is inserted into the base 33 from a notch of the base 33, and moves forward and backward (as indicated by arrow X) relative to the base 33, so that a user can actuate the driving component 3d after pressing the pressing member 32.

In addition, a first limiting member 321 and a second limiting member 322 can be respectively disposed on the left and right sides of the slot of the base 33 as required, so as to dispose the pressing member 32 between the first limiting member 321 and the second limiting member 322, thereby facilitating the installation of the pressing member 32. For example, the first limiting member 321 is an arched sheet, and the second limiting member 322 is a flat sheet, so that the first limiting member 321 is inserted into the base 33, the left side of the pressing member 32 is aligned to cover the first limiting member 321, and the second limiting member 322 is located on the notch of the base 33 to cover the oblique side 32b on the right side of the pressing member 32. Preferably, the first limiting member 321 may have a bevel edge 321a corresponding to the bevel edge 32a of the pressing member 32.

In addition, the shell assembly 3b can be configured with a protective shell 33a at the right end of the base 33 as required, as shown in fig. 2A, and the protective shell 33a is fixed on the door panel 2, so that the carrying assembly 3a and the protective shell 33a can erect the left and right ends of the base 33.

The action assembly 3c includes a first action structure 34 linking the pressing member 32 and the driving assembly 3d and a second action structure 35 linking the pressing member 32, and the first action structure 34 and the second action structure 35 are arranged at intervals.

In the present embodiment, the first acting structure 34 is a main acting structure, and as shown in fig. 3B to fig. 3D, it includes a first supporting member 34a and a first pulling member 343 disposed on the first supporting member 34 a. For example, the first supporting member 34a is substantially "L-shaped" and fixed on the bottom of the base 33 (near the carrying component 3a), and the first supporting member 34a is formed with a first inclined groove 340 at the right frame, and the inclined direction and angle of the first supporting member 34a relative to the base 33 correspond to the inclined direction and angle of the

inclined sides

32a,32b of the pressing member 32 relative to the base 33. Specifically, the first inclined groove 340 is configured with a first acting rod 341 for fixedly connecting the pressing member 32, so that the first acting rod 341 moves along the first inclined groove 340 to drive the pressing member 32 to move.

In addition, the first supporting member 34a is disposed with a first fixing rod 342 at the left frame body for fixing the first pulling member 343. For example, the first pulling member 343 is a torsion spring that is coupled to the first supporting member 34a by the first fixing rod 342, and one end 343a (shown in fig. 3C) of the first pulling member 343 is fixed to the first acting rod 341, and the other end 343B (shown in fig. 3B) is fixed to the base 33.

In addition, the second active structure 35 is an auxiliary active structure, as shown in FIG. 3E, and has a configuration substantially the same as that of the first active structure 34, and includes a second support member 35a and a second traction member 353 disposed on the second support member 35 a. For example, the second support 35a is substantially "L-shaped" and fixed to the bottom of the base 33 (away from the supporting component 3a or close to the protective shell 33a), and the second support 35a has a second inclined groove 350 formed at the right frame, and the inclined direction and angle of the second support with respect to the base 33 correspond to the inclined direction and angle of the

inclined sides

32a,32b of the pressing member 32 with respect to the base 33. Specifically, the second inclined groove 350 is used to configure a second action rod 351 for fixedly connecting the pressing member 32, so that the second action rod 351 moves along the second inclined groove 350 to drive the pressing member 32 to move.

In addition, the second supporting member 35a is configured with a second fixing rod 352 at the left frame body for fixing the second pulling member 353. For example, the second pulling member 353 is a torsion spring, which is pivotally connected to the second supporting member 35a via the second fixing rod 352, and one end 353a (as shown in fig. 3E) of the second pulling member 353 is fixed to the second acting rod 351, and the other end 353B (as shown in fig. 3B) is fixed to the base 33.

The driving assembly 3d includes an adapter 36 for linking the first action rod 341, a linkage 37 connected to the adapter 36 in a displaceable manner, and a shift lever 39 connected to the linkage 37.

In this embodiment, the adaptor 36 is a single short strip, one end (e.g., right end) of which is pivotally connected to the first action bar 341 as shown in fig. 3C and 3D, and the other end (e.g., left end) of which is movably connected to the linking member 37.

In addition, the linking member 37 is a double-strip piece, one end of which holds the adaptor 36, and the other end of which is bent to form a hook 37a for pivotally connecting the lever 39. For example, the linking member 37 has a groove 370, through which a driving rod 37B (as shown in fig. 3B) fixed to the adaptor 36 passes, so that the adaptor 36 pulls the linking member 37 by the driving rod 37B, and a limiting member 38 is disposed on the left frame of the first supporting member 34a and is erected around the groove 370 of the linking member 37.

Therefore, when the pressing member 32 is forced to move downward in the direction of the bottom of the base 33, the first action rod 341 is linked to move in the same direction, so that the right end of the adaptor 36 moves in the same direction, and the left end of the adaptor 36 drives the linking member 37 and the driving rod 37b to swing together by the torque of the first traction member 343, so that the arrangement direction of the adaptor 36 is changed from the inclined state to the horizontal state, at this time, the linking member 37 bears the switching action of the adaptor 36 to generate a pulling force F (as shown in fig. 3D), and the movement limiting member 38 prevents the linking member 37 from jumping off, so that the linking member 37 can generate a pulling force F in the horizontal direction (as shown in the arrow direction Y).

In addition, the shift lever 39 is pivoted to the hook 37a and protrudes out of the shift hole 310 of the seat 31 to extend into the lock hole 20 (shown in fig. 2B) of the cassette device 2a, and is swung (in a swing direction W shown in fig. 3C) by the pushing and pulling operation of the linking member 37 to drive the lock bolt 21 to move horizontally (in an arrow direction Y). For example, one end of the shift lever 39 is a swivel (e.g., wheel-shaped) protruding out of the adjusting hole 310 of the seat 31, and the other end of the shift lever 39 is coupled to the supporting point hole 311 of the seat cover 31a via a supporting point lever 390 (as shown in fig. 3B), so that the shift lever 39 swings relative to the seat cover 31 a.

In addition, the driving component 3d can be configured with an elastic element 38a, such as a telescopic spring, sleeved on the linking member 37, one end of which is fixed on the movement limiting member 38, and the other end of which is clamped on the fixing portion 371 (shown in fig. 3C) at the middle section of the linking member 37.

When the door handle device 3 is used, as shown in fig. 2A and 2B, when the user pushes (in the pushing direction P shown in fig. 2A) the pressing member 32, the pressing member 32 is tilted toward the bottom of the base 33 in the oblique direction D shown in fig. 2A by the engagement of the oblique sides 32A,32B of the pressing member 32 and the first oblique groove 340 (and/or the second oblique groove 350), at this time, the adaptor 36 drives the linkage 37 to generate the pulling force F in the horizontal direction Y1 (shown in fig. 2A) to swing the shift lever 39, so that the shift lever 39 shifts (in the shifting direction W1 shown in fig. 2B) the components of the lock box device 2A to retract the lock bolt 21 into the lock box device 2A (in the horizontal direction Y1 shown in fig. 2A), thereby completing the unlocking operation of the door panel 2.

On the other hand, when the user releases the pressing member 32, the elastic element 38a cooperates with the first pulling member 343 (and/or the second pulling member 353) to make the pressing member 32 move obliquely in a direction away from the base 33, and at this time, the adaptor 36 drives the linkage 37 to generate a pushing force in a horizontal direction Y2 (as shown in fig. 2A) to swing the shift lever 39, so that the shift lever 39 shifts (in a shifting direction W2 shown in fig. 2B) the components of the lock box device 2A to make the lock bolt 21 protrude out of the lock box device 2A (in a horizontal direction Y2 shown in fig. 2A).

To sum up, the door handle device 2 of the present application mainly utilizes the design of the bevel edges 32a and 32b of the pressing member 32, so that when the user pushes the pressing member 32 in the direction perpendicular to the door panel 2, the pressing member 32 can move obliquely toward the bottom of the base 33 to drive the shift lever 39 to actuate the lock bolt 21 of the lock box device 2a, compared with the prior art, the components of the acting component 3c and the driving component 3d of the door handle device 2 of the present application can be very simple, thereby not only reducing the manufacturing cost, but also avoiding the problem of unsmooth actuation caused by mechanical matching error.

In addition, the door handle device 2 of this application only needs to connect the first effect structure 34 and the drive subassembly 3d that should act on subassembly 3c, and need not to connect this second effect structure 35, so when the maintenance, only need change this first effect structure 34, and need not whole group's effect subassembly 3c and change, therefore be favorable to quick replacement effect structure.

It should be understood that the second active structure 35 can be omitted from the active component 3c as required, which is more advantageous for saving the manufacturing cost and more advantageous for maintenance.

The above embodiments are merely illustrative of the principles and utilities of the present application and are not intended to limit the application. Modifications and variations can be made to the above-described embodiments by those of ordinary skill in the art without departing from the spirit and scope of the present application. Therefore, the protection scope of the present application should be as set forth in the claims.
