It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

As one aspect of the present disclosure, there is provided a handle, wherein the handle includes a mounting base 100, a clip 200, a clip arm 300, and an operating handle 400, as shown in fig. 1. The locking arm 300 includes a first locking arm 310 and a second locking arm 320, a first end of the first locking arm 310 is connected to the mounting base 100, a second end of the first locking arm 310 is connected to a first end of the second locking arm 320, the locking member 200 is disposed on the first locking arm 310, and the locking member 200 protrudes toward the handle, the first locking arm 310 can be elastically deformed, and the operating handle 400 is connected to the mounting base 100.

The mounting base 100 is configured to be mounted on the panel main body 600 of the dummy panel, and make the first engaging arm 310 protrude from an edge of the panel main body 600 on which the mounting base 100 is mounted, where the first engaging arm 310 can be elastically deformed to drive the engaging member 200 to move toward the mounting base 100 when the second engaging arm 320 receives an external force toward the mounting base 100.

It should be noted that, herein, "external force of the mount 100" means that at least a part of the force is directed toward the mount 100. Here, the "movement of the engaging member 200 toward the mount 100" is also that the movement tendency of the engaging member 200 is closer to the mount 100.

It should be noted that the first engagement arm 310 is made of an elastically deformable material (e.g., plastic). As shown in fig. 2, 3 and 10, the pull handle is mounted on the panel body 600 to form a dummy panel. As shown in fig. 2, a dummy panel provided with the pull handle is inserted into the insert box 700. As shown in fig. 4, the engaging member 200 on the engaging arm 300 is received in the engaging groove 710a of the holder 710 (wherein the holder 710 is disposed in the slot of the socket 700), and the engaging member 200 abuts against the sidewall of the engaging groove 710a, so that the dummy panel is prevented from being removed from the socket 700, and the second end of the second engaging arm 320 is located outside the slot. When the dummy panel is to be removed from the socket, pressure may be applied to the second end of the second engaging arm 320 to disengage the engaging member 200 from the socket (fig. 6 shows the engaging member disengaged from the engaging groove 710 a). At this time, the operator pulls the operation handle 400 to pull the dummy panel out of the socket.

In the present disclosure, whether the second engaging arm 320 is elastically deformable is not particularly limited. As an alternative embodiment, the first engaging arm 310 and the second engaging arm 320 are integrally formed, that is, the second engaging arm 320 is also elastically deformable. Therefore, the engaging arm 300 can be obtained by integrally molding the engaging arm with a plastic material.

It should be noted that, for convenience of processing, the card holder 710 is detachably disposed in the slot of the socket 700. For example, the card holder 710 may be disposed in the slot of the cartridge 700 by fastening a bolt or a fastening screw.

In the locked state of the dummy panel inserted into the insertion box, as shown in fig. 7, when the dummy panel is subjected to an external force to generate an outward movement trend, the side wall of the clamping groove gives a reaction force F to the clamping member 200, and in general, the structural design of the side wall of the clamping groove has a certain inclination, the reaction force F can be decomposed into a component force F1 along the side wall direction of the clamping groove and a force F2 in an outward direction, so as to form a moment for enabling the side wall of the clamping groove to rotate outwards, thereby achieving the effect of locking more and more by the external force under the condition of non-active unlocking and realizing the locking function.

By providing the engaging arm 300 and the engaging member 200, the dummy panel can be reliably fixed in the insertion box, and the dummy panel can be conveniently detached from the insertion box, and the handle is simple in structure.

In the present disclosure, the specific structure of the engaging arm 300 is not particularly limited. In the embodiment shown in fig. 1, 8 and 9, the lever 400 and the engagement arm 300 are located on both sides of the mount 100, respectively. In order to facilitate the operation, reduce the volume of the engaging arm 300, and improve the compactness, optionally, an angle between the first engaging arm 310 and the second engaging arm 320 is an obtuse angle, so that the second end of the second engaging arm 320 is directed to the operation handle 400. The engagement arm 300 has a substantially V-shape.

As shown in fig. 4, when the engaging member 200 is engaged in the socket, the space between the first engaging arm 310 and the socket is small, or even no space exists, and the second engaging arm 320 is located outside the socket. An obtuse angle exists between the second engaging arm 320 and the first engaging arm 310, so that a space between the second end of the second engaging arm 320 and the insertion box is large enough to facilitate application of an operating force to the second engaging arm 320.

In the present disclosure, the angle between the first engaging arm 310 and the second engaging arm 320 is not particularly limited, and alternatively, the angle between the first engaging arm 310 and the second engaging arm 320 may be between 100 ° and 150 °.

In the present disclosure, the arrangement of the operation lever 400 is not particularly limited. In the embodiment shown in fig. 4, 8 and 9, the first end of the lever 400 is fixedly connected to the mounting block 100, and the second end of the lever 400 is a free end.

In the present disclosure, how to apply pressure to the second engaging arm 320 is not particularly limited. For example, in the embodiment shown in fig. 9, pressure may be applied directly by an operator to the second end of the second engagement arm 320. For anti-slip, an anti-slip structure may be provided on the outer surface of the second engagement arm 320. In the present disclosure, the specific type of the anti-slip structure is not particularly limited. For example, the anti-slip structure may include a plurality of anti-slip grooves, and may also include a plurality of anti-slip strips.

In order to facilitate the operation of the operator, as shown in fig. 4, the pull handle further includes a conductive member 500, wherein a first end of the conductive member 500 is connected to a first end of the operating handle 400, a second end of the conductive member 500 extends beyond a second end of the second engaging arm 320, and a portion of an inner surface of the conductive member 500 is opposite to a portion of an outer surface of the second engaging arm 320, so that the conductive member 500 contacts the second end of the second engaging arm 320 at least when the first engaging arm 310 is deformed by the force of the engaging member 200 to move the second end of the second engaging arm 320 away from the mounting seat 100.

In the present disclosure, the provision of the conductive member 500 can restrict the movement of the second engagement arm 320, so that it can be ensured that the engagement member 200 can be engaged in the engagement groove when the dummy panel is mounted in the socket.

As an alternative embodiment, a portion of the inner surface of the conductive member 500 remains in contact with a portion of the outer surface of the second snap arm 320, thereby restricting movement of the second snap arm 320. Of course, the present disclosure is not limited thereto, and for convenience of processing, as shown in fig. 4, a space exists between a portion of the inner surface of the conductive member 500 and a portion of the outer surface of the second engagement arm 320, as long as the second engagement arm 320 can be ensured to contact the second end of the second engagement arm 320 when the second engagement arm 320 moves away from the mount 100.

In the present disclosure, the operation handle 400 can rotate relative to the mounting base 100 and drive the conductive member 500 to move to contact with the second end of the second engaging arm 320, so as to apply an external force to the second end of the second engaging arm 320 toward the mounting base 100, and enable the second end of the second engaging arm 320 to slide along the conductive member under the condition that the second end is subjected to the external force toward the mounting base 100, thereby ensuring that the engaging member 200 is disengaged from the engaging groove.

That is, when the operator pulls the operation handle 400, the second end of the conductive member 500 rotates toward the second end of the second engaging arm 320 until contacting the second end of the second engaging arm 320, and as the operator pulls the operation handle 400 further, the second end of the conductive member 500 applies pressure to the second end of the second engaging arm 320, so that the engaging member 200 is finally disengaged from the engaging groove.

In the present disclosure, the structure of the operation lever 400 is not particularly limited. As an alternative embodiment, the operation handle 400 may be a straight rod. In the embodiment shown in fig. 4, the lever 400 includes a vertical portion having a first end connected to the mount 100 and an inclined portion having a first end connected to a second end of the vertical portion and a second end of the inclined portion facing the mount.

The operator can pull the tilting portion to effect operation of the handle 400. For anti-slip, an anti-slip strip may optionally be provided on the inclined portion.

In order to increase the strength of the second engaging arm 320, and the angle between the second engaging arm 320 and the first engaging arm 310 is not changed, optionally, the engaging arm 300 further includes a first reinforcing rib 330, a portion of the first reinforcing rib 330 is located on an inner surface of the first engaging arm 310, another portion of the first reinforcing rib 330 is located on an inner surface of the second engaging arm 320, and a length of a portion of the first reinforcing rib 330 located on the second engaging arm 320 is greater than a length of a portion of the first reinforcing rib 330 located on the first engaging arm 310.

In order to increase the strength of the conductive member 500, the pull handle may optionally further include a second reinforcing rib 510 provided on the conductive member 500. The second stiffener 510 is located on the surface of the conductive member facing the second snap arm 320.

In the present disclosure, the specific structure of the mount 100 is not particularly limited, as long as the handle can be fixed to the panel body by the engagement seat.

In the embodiment shown in fig. 4, the mounting base 100 includes a mounting portion 130, a first suspension plate 110 and a second suspension plate 120, a first end of the first suspension plate 110 is connected to the mounting portion 130, a second end of the first suspension plate 110 is connected to a first end of the first engagement arm 310, a first end of the second suspension plate 120 is connected to the mounting portion 130, an angle exists between the first suspension plate 110 and the first engagement arm 310, and a second end of the second suspension plate 120 is connected to the operation handle 400. As an alternative embodiment, the second suspension plate 120 is elastically deformable, so that the operation handle 400 can be rotated with respect to the mounting base 100.

The mounting portion 130 is fixed to the panel body, and the first cantilever 110 protrudes from the socket mating surface of the panel body, so that the latch arm 300 is facilitated to rotate clockwise about the first end (a point a in fig. 5) of the first latch arm 310, and the latch 200 is released from the latch slot.

The provision of the second hanger plate 120 can increase the distance between the operation handle 400 and the panel body, facilitating the grasping of the operator. Also, the second hanger plate 120 is easily elastically deformed, so that the conductive member 500 is more easily moved to be in contact with the second engagement arm 320.

In the present disclosure, the specific structure of the mounting portion 130 is also not particularly limited. As shown in fig. 1, the mounting part 130 includes a first mounting plate 131, a second mounting plate 132, and a third mounting plate 133, a first end of the first mounting plate 131 is connected to a first end of the second mounting plate 132, a second end of the first mounting plate 131 is connected to a first end of the third mounting plate 133, a second end of the third mounting plate 133 is connected to a second end of the first mounting plate 131, the first hanger plate 110 is connected to the mounting part 130 at a junction of the first mounting plate 131 and the second mounting plate 132, and the second hanger plate 120 is connected to the mounting part 130 at a junction of the first mounting plate 131 and the third mounting plate 133.

The first, second and third mounting plates 131, 132, 133 enclose a triangular stable structure, so that the structural strength of the mounting part 130 can be improved. In the present disclosure, the first mounting plate 131 is fixed to the panel body.

In the present disclosure, there is no particular limitation on how the first mounting plate 131 is fixed to the panel body. For example, the first mounting plate 131 may be fixed to the panel body by means of an adhesive or the like.

For maintenance, a fastening hole penetrating the first mounting plate 131 in the thickness direction is formed on the first mounting plate 131. Accordingly, a fitting hole is also provided on the panel body, and the first mounting plate 131 may be fixed to the panel body by providing a fastener in the fastening hole and the fitting hole. To facilitate the determination of the position of the handle on the dummy panel, the first mounting plate 131 is optionally formed with a locating pin 134 protruding from the outer surface of the first mounting plate 131 (i.e., the surface of the first mounting plate 131 that is in contact with the dummy panel).

The working principle of the pull handle provided in one aspect of the present disclosure is explained and illustrated with reference to fig. 5 and 6. When the dummy panel is inserted into the receptacle and locked, the second engaging arm 320 is pressed inward by the conductive member 500 under the leverage by pulling the operation handle outward by a human hand, and the second engaging arm 320 is rotated inward by elastic deformation. The elastic deformation of the second engaging arm 320 results from the substantially V-shaped configuration of the engaging member. When unlocking, the conductive piece 500 is first lapped on the b plane of the second clamping arm 320 and transmits pressure, and as the conductive piece 500 is pressed down and deepened, the conductive piece 500 and the second clamping arm 320 relatively slide on the b plane along the direction indicated by the arrow, so that the conductive piece 500 can be always pressed on the second clamping arm 320 and stably transmit pressure. The rotation of the second engaging arm 320 mainly results from the elastic bending deformation of the c-section (i.e., the first engaging arm 310) of the engaging arm 300, which can be approximately regarded as circular motion around the point a, and the second engaging arm 320 rotates around the point a until the engaging member 200 is disengaged from the engaging groove, at which time unlocking is completed, as shown in fig. 6, the dummy panel can be freely inserted and removed, and automatically rebounds to a normal state after the force is removed.

As a second aspect of the present disclosure, as shown in fig. 10, there is provided a dummy panel, where the dummy panel includes a panel body 600 and at least one handle, the panel body 600 includes an outer operation surface 601 and two socket engagement surfaces 602, the two socket engagement surfaces 602 are located at two ends of the outer operation surface 601, respectively, and the handle is disposed at an end of the outer operation surface, where the handle is provided in the first aspect of the present disclosure, the mounting portion 130 is fixed at an end of the outer operation surface 601, and the engaging arm 300 protrudes from the corresponding socket engagement surface 602.

As described above, the snap arms 300 are made of a deformable material (e.g., plastic). The dummy panel provided with the pull handle is inserted into the insert box 700. The engaging member 200 of the engaging arm 300 is received in the slot of the socket 700, and the engaging member 200 abuts against the sidewall of the slot, so that the dummy panel is prevented from being removed from the socket 700, and the second end of the second engaging arm 320 is located outside the slot. When the dummy panel is to be removed from the socket, pressure may be applied to the second end of the second engaging arm 320 to disengage the engaging member 200 from the socket. At this time, the operator pulls the operation handle 400 to pull the dummy panel out of the socket.

As a third aspect of the present disclosure, as shown in fig. 2, there is provided a communication device, where the communication device includes an enclosure 700 and at least one dummy panel, the enclosure includes a plurality of pairs of slots, at least one pair of the slots is provided with the dummy panel, where the dummy panel is the dummy panel provided in the second aspect of the present disclosure, and the enclosure further includes a card holder 710 disposed in the slot, and a clamping groove is formed on the card holder 710. The first clamping arms and the clamping pieces are located in corresponding slots, the clamping pieces are inserted into corresponding clamping grooves and abutted against the side walls of the corresponding clamping grooves, and the second clamping arms are located outside the corresponding slots.

It should be noted that at least one board may also be provided in the communication device, where the board is also provided in the corresponding slot.
