The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] To solve relevant technical problems, such as Figure 1 to Figure 2 As shown, the embodiment of the utility model provides a built-in auxiliary pull-out structure of a drawer, and the built-in auxiliary pull-out structure includes:

[0039] Connector body 1;

[0040] A handle 2, which is hinged to the side of the connector body 1 through a rotating shaft 10, and includes a first portion 21 and a second portion 22 located on both sides of the rotating shaft 10;

[0041] A first limiting assembly 3 is disposed on a side of the connector body 1, and the first limiting assembly 3 is configured to be operable to fix and release the handle 2 when the handle 2 is in the first position 4;

[0042] The fixing portion 7, the connector body 1 can be pulled out relative to the fixing portion 7, the fixing portion 7 is located on the side of the connector body 1 and corresponds to the second portion 22, and the second portion 22 and the fixing portion 7 are kept against each other during the process of the handle 2 rotating from the second position 5 to the third position 6, so as to pull out the connector body 1;

[0043] When the handle 2 is in the first position 4 , the upper end surface of the handle 2 is lower than or flush with the upper end surface of the connector body 1 .

[0044] In this embodiment, the connector body 1 is used as a high-speed connector in a network device, and includes a plurality of densely arranged pins or sockets. When installing, the pins or sockets are inserted into the corresponding connection ends by pushing forward, and when disassembling, they are pulled back to be separated from the corresponding connection ends. In this embodiment, the handle 2 and the fixing portion 7 are used as a pull-out aid structure when disassembling the connector body 1, and the first limit assembly 3 is used as a structure for fixing the handle 2 before, during, after, and after the connector body 1 is installed.

[0045] In this embodiment, if Figure 2 As shown, before, during and after the connector body 1 is installed, the handle 2 is in the first position 4 and is fixed by the first limit assembly 3. The upper end surface of the handle 2 in the first position 4 is lower than or flush with the upper end surface of the connector body 1, so that the handle 2 can be hidden in the side of the connector body 1 and is not exposed during the use of the connector body 1, thereby improving the aesthetics of the connector body 1.

[0046] In this embodiment, the assisted extraction process of the handle 2 is achieved by rotating the handle 2, so the handle 2 is hinged to the side of the connector body 1 through the rotating shaft 10, and the parts of the handle 2 located on both sides of the rotating shaft 10 are divided into a first part 21 and a second part 22. When the first part 21 of the handle 2 rotates, the second part 22 rotates accordingly. When fixing the handle 2, the first limiting component 3 can be connected to the first part 21 or the second part 22 of the handle 2, or connected to the rotating shaft 10 on the handle 2 to limit the rotation of the handle 2. In this embodiment, there is no restriction on the specific connection part of the first limiting component 3 on the handle 2, and it can be designed according to actual needs. In addition, the specific connection relationship between the first limiting component 3 and the handle 2 is not limited in this embodiment. In some embodiments, the first limiting component 3 and the handle 2 can be connected by a snap-on method, or by a plug-in method, etc.

[0047] When the connector body 1 needs to be pulled out, the first limit assembly 3 can be adjusted to release the handle 2, and then the first portion 21 of the handle 2 can be driven to rotate toward the installation direction of the connector body 1. Figure 1 As shown, after the handle 2 is rotated to the second position 5, the second portion 22 of the handle 2 abuts against the fixed portion 7. In this embodiment, the fixed portion 7 can be fixed on other accessories as a fulcrum for movement and remain motionless, for example, it can be fixed on a frame on which the connector body 1 is installed, etc. When the second portion 22 of the handle 2 abuts against the fixed portion 7, as the handle 2 is further rotated, the fixed portion 7, as a fulcrum for movement, will provide a reaction force to the handle 2, and the reaction force can act on the connector body 1, so that the connector body 1 moves backward as a whole. As the handle 2 is further rotated, the connector body 1 will gradually detach from the connection end, thereby realizing the function of assisting the removal of the connector body 1. In this embodiment, when the handle 2 is rotated to the third position 6, the connector body 1 can be completely detached from the connection end or has moved backward to a position that is convenient for detaching from the connection end.

[0048] After the handle 2 is rotated to the third position 6, the handle 2 can be rotated back to the first position 4 and fixed by the first stop assembly 3. After being fixed, the connector body 1 can be pulled out as a whole. Of course, it can be understood that when the handle 2 is rotated to the third position 6, the connector body 1 is already in a detachable position, so the connector body 1 can also be directly pulled out.

[0049] The utility model achieves the technical effect that when the connector body 1 is pulled out and disengaged forward and backward, the pulling-out assistance structure formed by the handle 2 can be hidden on the side of the connector body 1 after the connector body 1 is installed, thereby solving the problem in the related art that when the connector has the requirement of being pulled out and disengaged forward and backward, the pulling-out assistance structure on the connector is exposed on the connector.

[0050] Since the disengagement of the connector body 1 is achieved by the reaction force exerted on the handle 2 located on the side of the connector body 1 during the rotation process, in order to balance the force on the connector body 1 when disengaging, the handle 2 in this embodiment is arranged on both sides of the connector body 1, and the limit assembly is arranged on both sides of the connector body 1.

[0051] Specifically, during operation, the handles 2 on both sides of the connector body 1 can be rotated simultaneously, so that both sides of the connector body 1 are subjected to a certain reaction force, so that the connector body 1 can be smoothly detached.

[0052] Since the detachment of the connector body 1 is achieved by the second portion 22 of the handle 2 abutting against the fixing portion 7, and the fixing portion 7 provides a reaction force under the continuous rotation of the handle 2. Therefore, in order to enable the reaction force to better act on the detachment of the connector body 1 in the horizontal direction, the reaction force needs to be decomposed in the horizontal direction as much as possible. At the same time, since the first portion 21 of the handle 2 needs to be operated, the first portion 21 needs to have a certain length to provide sufficient force arm requirements, and it is also necessary to make the upper end surface of the handle 2 in the first position 4, flush with or lower than the upper end surface of the connector body 1.

[0053] Therefore, after considering the above factors, if Figure 1 and Figure 2 As shown, in this embodiment, the handle 2 is configured as a crank structure, that is, an obtuse angle is formed between the first portion 21 and the second portion 22 , the rotating shaft 10 is located below the first portion 21 , and the fixing portion 7 is close to or located at the lateral horizontal midline of the connector body 1 .

[0054] Specifically, when the handle 2 in this embodiment is in the first position 4, the first portion 21 is in a horizontal state, and the second portion 22 is tilted downward and expanded relative to the first portion 21. The first portion 21 in a horizontal state can provide a sufficient force arm for the operation process and can also be better hidden on the side of the connector body 1. The second portion 22 in an inclined state can better decompose the reaction force into the horizontal direction after rotating to contact the fixing portion 7 to help the connector body 1 to be disengaged.

[0055] According to the structural design, when the handle 2 is rotated to the third position 6, the connector body 1 also moves backward to a disengageable position. Therefore, in order to limit the handle 2 to the third position 6 and accurately determine that the handle 2 has been rotated to the third position 6, as shown in FIG. Figure 1 and Figure 2 As shown, the extraction assistance structure in this embodiment further includes a second limiting component 8, which is disposed on the side of the connector body 1 and corresponds to the handle 2;

[0056] The second limiting assembly 8 and the first limiting assembly 3 are respectively located on both sides of the handle 2 . The second limiting assembly 8 is used to abut against the handle 2 when the handle 2 rotates to the third position 6 to limit the maximum rotation angle of the handle 2 .

[0057] Specifically, in this embodiment, when the handle 2 rotates from the first position 4 toward the third position 6, the handle 2 will gradually approach the second limit assembly 8. When the handle 2 rotates to the third position 6, the handle 2 will abut against the second limit assembly 8, thereby limiting the further rotation of the handle 2 under the action of the second limit assembly 8, and also reminding the operator that the connector body 1 is in a detachable position. In this embodiment, in order to enable the second limit assembly 8 to play a corresponding role, the second limit assembly 8 can be a protruding structure protruding from the side of the connector body 1, which acts as a corresponding limit structure by abutting against the side of the handle 2. In one embodiment, the second limit assembly 8 is configured as a second limit nail 81.

[0058] In one embodiment of the first limiting component 3, as Figure 1 and Figure 2 As shown, the first limiting assembly 3 includes a handle anti-drop device 31 and an elastic member 33; wherein,

[0059] The first end of the handle anti-detachment device 31 is hinged to the side of the connector body 1, the second end of the handle anti-detachment device 31 is provided with a first limiting structure 34, the first portion 21 of the handle 2 is provided with a second limiting structure 23, and the first limiting structure 34 and the second limiting structure 23 can be engaged with each other;

[0060] The first end of the elastic member 33 is connected to the handle anti-detachment device 31, and the second end of the elastic member 33 is connected to the connector body 1. The elastic member 33 is used to apply a force to the handle anti-detachment device 31 that enables the first limiting structure 34 and the second limiting structure 23 to engage with each other.

[0061] In this embodiment, the handle anti-detachment device 31 fixes and releases the handle 2 by rotating, and fixes the handle 2 by connecting with the first portion 21 of the handle 2. Accordingly, in this embodiment, the second end of the handle anti-detachment device 31 is provided with a first limiting structure 34, and the second portion 22 of the handle 2 is provided with a second limiting structure 23, and the handle 2 is fixed by the mutual engagement of the first limiting structure 34 and the second limiting structure 23.

[0062] In order to enable the handle anti-detachment device 31 to apply sufficient fixing force to the handle 2 so that the handle 2 cannot be easily rotated. In this embodiment, an elastic member 33 is also provided, and the two ends of the elastic member 33 are respectively connected to the handle anti-detachment device 31 and the connector body 1. The elastic member 33 applies a force to the handle anti-detachment device 31 to rotate in the direction of the handle 2, so that the first limiting structure 34 and the second limiting structure 23 can be tightly engaged. At the same time, under the action of the elastic member 33, when the handle anti-detachment device 31 rotates in the direction away from the handle 2, the elastic force applied by the elastic member 33 can also automatically reset the handle anti-detachment device 31.

[0063] In some embodiments of the elastic member 33, the elastic member 33 may be configured as a spring or a tension spring. In this embodiment, the elastic member 33 is preferably a tension spring, and both ends of the tension spring are connected to the connector body 1 and the handle anti-drop device 31 respectively.

[0064] In order to make the handle 2 more stable after being fixed, Figure 2 As shown, the first limit assembly 3 in this embodiment also includes a first limit pin 9, which corresponds to the side of the handle anti-detachment device 31 facing the rotating shaft 10 and is used to limit the maximum rotation angle of the handle anti-detachment device 31 when fixing the handle 2.

[0065] Specifically, in this embodiment, the handle anti-slip device 31 is pressed against the first limiting nail 9 under the action of the elastic member 33, and the first limiting structure 34 and the second limiting structure 23 are engaged with each other. At this time, even if the handle 2 is subjected to downward pressure, the handle anti-slip device 31 cannot be further rotated counterclockwise under the action of the first limiting nail 9, so the handle 2 cannot be further rotated. Under the pulling force of the elastic member 33, the handle anti-slip device 31 cannot be further rotated clockwise, so the handle 2 cannot be further moved, so that the handle 2 can be fixed to the current position, that is, fixed to the first position 4.

[0066] On this basis, in order to further improve the stability of the handle 2 after it is fixed, and to facilitate the engagement of the first limiting structure 34 and the second limiting structure 23 when the handle 2 is fixed, the position of the first limiting nail 9 in this embodiment can not only abut against the side surface of the handle anti-detachment device 31, but also abut against the lower end surface of the first part 21 on the handle 2, that is, when the handle 2 is in the first position 4, the first limiting nail 9 can support the handle 2.

[0067] Specifically, during operation, when the handle 2 rotates to abut against the first limiting pin 9 , it indicates that the handle 2 is in the first position 4 , and at this time, the handle anti-detachment device 31 can be operated to fix the handle 2 in the first position 4 .

[0068] In an implementation of the first limiting structure 34 and the second limiting structure 23, the first limiting structure 34 includes a limiting protrusion, and the second limiting structure 23 includes a limiting groove, and the limiting protrusion and the limiting groove can engage with each other.

[0069] In this embodiment, since the handle 2 and the handle anti-drop device 31 both perform rotational motion, in order to enable the limiting protrusion and the limiting groove to engage more smoothly under the rotational motion environment, the limiting protrusion and the limiting groove both have a certain inclination angle.

[0070] Since the elastic member 33 can exert a force on the handle anti-offset device 31 to make it abut against the first limiting nail 9, when the handle 2 leaves the first position 4, the handle anti-offset device 31 will abut against the first limiting nail 9. In order to facilitate the fixation of the handle 2 after it is rotated back to the first position 4, the limiting protrusion and the first portion 21 of the handle 2 are further improved in this embodiment, so that when the handle 2 is rotated back to the first position 4, the handle anti-offset device 31 can be automatically pushed to rotate and the handle 2 is fixed.

[0071] Specifically, in this embodiment, a first introduction surface is provided on a side of the limiting protrusion facing the first portion 21 , and a second introduction surface that can be tangent to the first introduction surface is provided at an end of the first portion 21 .

[0072] During operation, the second guide surface of the first part 21 first contacts the first guide surface of the limiting protrusion. As the handle 2 rotates further, the second guide surface applies a thrust to the first guide surface, thereby pushing the handle anti-slip device 31 to rotate clockwise by a certain angle to let the handle 2 rotate in, so that the handle 2 can rotate to the first position 4 and abut against the first limiting pin 9. At this time, the first guide surface is staggered with the second guide surface, so the first guide surface no longer applies a thrust to the first guide surface. Under the action of the elastic member 33, the handle anti-slip device 31 automatically resets and causes the limiting protrusion and the limiting groove to bite, completing the fixation of the handle 2. Through this structure, the present embodiment does not need to operate the handle anti-slip device 31 additionally during the fixation process of the handle 2 in the first position 4.

[0073] In order to facilitate the operation of the handle anti-detachment device 31 to release the handle 2, a pressing handle 32 is further provided on the handle anti-detachment device 31 in this embodiment.

[0074] According to another aspect of the utility model, a network device is provided, comprising the above-mentioned built-in auxiliary extraction structure.

[0075] The above description is only the preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement, etc. made shall be included in the protection scope of the utility model.
