Technical Field

[0001] This utility model relates to the field of chassis handle technology, specifically a dual-handle power handle. Background Technology

[0002] Application number CN2019103171688, entitled "A Server Chassis Handle," describes a server chassis handle belonging to the technical field of server chassis. The handle includes two handles, each comprising a connecting plate and an external pull member. The external pull member is fixed to the front of the connecting plate, and the rear of each connecting plate is fixed to a side panel of the server chassis. Each connecting plate has a positioning protrusion in its middle, which passes through the side panel of the server chassis and engages with the side panel of the server rack. The invention aims to solve the technical problem of inconvenient server chassis pull-out. However, the handle design only has a single assist structure, resulting in an unbalanced module assistance that requires operators to apply significant force to complete these operations, leading to high labor intensity and low efficiency. Summary of the Invention

[0003] In order to overcome the shortcomings of existing technical solutions, this utility model provides a dual-handle power-assisted handle, which can effectively solve the problem of unbalanced module assistance that requires a large force to complete the operation.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a double-handle power handle, including a mounting plate and a frame, wherein two movable handles and a base located between the handles are movably mounted on the mounting plate, and a button is provided on the top of the base, and the handles are locked to the top of the base by the button; The mounting plate has protrusions on its inner side, and the protrusions are located on the top and bottom sides of the mounting plate near the handle. The handle has a notch located on the outer side of the protrusion. The handle has a handle fastening hole as the axis of motion. The back of the handle has a second torsion spring placement groove with a second torsion spring limiting hole that passes through the second torsion spring placement groove. The second torsion spring is fixed in the second torsion spring placement groove. The end of the handle has a button locking hole. The base is provided with a base fastening hole, a first torsion spring placement groove, and a button fastening hole. The base fastening hole is equipped with a fastener, and the first torsion spring placement groove is fixed with a first torsion spring. The button is provided with a flip-out shaft pin hole, and the button is movably connected to the button fastening hole through the flip-out shaft pin. The front end of the button is provided with a locking protrusion.

[0005] Furthermore, the base is provided with at least one positioning post, which is arranged perpendicular to the surface of the base.

[0006] Furthermore, the positioning convex bulge is a slope with the inclined surface facing forward, and the inclination angle of the slope ranges from 15° to 60°.

[0007] Furthermore, the top of the button is provided with a prompt bulge, the height of which ranges from 1mm to 5mm.

[0008] Furthermore, both the first torsion spring and the second torsion spring are helical springs, with the wire diameter of the first torsion spring ranging from 0.5mm to 2mm and the wire diameter of the second torsion spring ranging from 0.3mm to 1.5mm.

[0009] Compared with existing technologies, the beneficial effects of this utility model are: this technical solution adopts a symmetrical design with two handles, ensuring a smooth and uniform extension and closure process of the module assembly through the coordinated action of two thrust points.

[0016] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Example

[0017] like Figure 1-7 As shown, this utility model provides a double-handle type 2 power-assisted handle 2, including a mounting plate 1 and a frame 20. The mounting plate 1 is movably mounted with two movable handles 2 and a base 3 located between the handles 2. A button 4 is provided on the top of the base 3, and the handles 2 are locked to the top of the base 3 by the button 4. The mounting plate 1 has a protrusion 22 on its inner side, and the protrusion 22 is located on the top and bottom sides of the mounting plate 1 near the handle 2. The handle 2 is provided with a notch 21, which is located on the outside of the protrusion 22. The handle 2 is provided with a handle fastening hole 5 as the axis of motion. When the handle 2 is locked, the notch 21 on the handle 2 is engaged with the protrusion 22 on the mounting plate 1, locking the mounting plate 1 and fastening the handle 2, thus limiting the shaking position of the handle 2. The back of the handle 2 is provided with a second torsion spring placement groove 6. The second torsion spring placement groove 6 is provided with a second torsion spring limiting hole 7 that penetrates the second torsion spring placement groove 6. The second torsion spring 9 is fixed in the second torsion spring placement groove 6. The second torsion spring 9 applies elastic force to the handle 2 up and down. The end of the handle 2 is provided with a button locking hole 8, which cooperates with the locking protrusion 18 of the button 4 to lock the handle 2. The base 3 is provided with a base fastening hole 11, a first torsion spring placement groove 12, and a button fastening hole 13. The base fastening hole 11 is equipped with a fastener 15, which fastens the base 3 to the mounting plate 1. The first torsion spring 16 is fixed in the first torsion spring placement groove 12. The button 4 is provided with a flip-out shaft pin hole 17. The button 4 is movably connected to the button fastening hole 13 through the flip-out shaft pin 14, so that the button 4 can rotate in a designated position. The front end of the button 4 is provided with a locking protrusion 18, and the shape and size of the locking protrusion 18 correspond to the button locking hole 8.

[0018] A button locking hole 8 is provided at the end of handle 2, which cooperates with the locking protrusion 18 of button 4 to lock handle 2. This allows handle 2 to be stably fixed on base 3 when not in use, avoiding additional resistance caused by handle 2 shaking. When operation is required, simply press button 4 to disengage the locking protrusion 18 from the button locking hole 8, and handle 2 can move easily under the combined action of the elastic force of the second torsion spring 9 and the external force of the operator, reducing the energy consumed due to the instability of handle 2 shaking.

[0019] The mounting plate 1 has two movable handles 2, which allows the handles 2 to be flexibly adjusted according to the operator's operating habits and direction of force. The operator can hold the handles 2 and apply force in the most comfortable and effortless posture, which improves the convenience and effortlessness of operation.

[0020] See Figure 6 The base 3 is provided with at least one positioning post 10. The positioning post 10 is arranged perpendicular to the surface of the base 3. When the base 3 is installed on the mounting plate 1, the positioning post 10 is inserted into the corresponding positioning hole on the mounting plate 1 to assist the positioning and installation of the base 3 on the mounting plate 1.

[0021] The positioning post 10 is set perpendicular to the surface of the base 3. When the base 3 is installed on the mounting plate 1, the positioning post 10 can be accurately inserted into the corresponding positioning hole on the mounting plate 1, ensuring that the base 3 is accurately positioned on the mounting plate 1, avoiding deviations that may occur due to manual installation, and enabling the base 3 to quickly and accurately reach the predetermined installation position.

[0022] After the positioning pin 10 is inserted into the positioning hole, it increases the connection area and number of connection points between the base 3 and the mounting plate 1 to a certain extent. This increased connection method makes the connection between the base 3 and the mounting plate 1 more stable and able to withstand greater external forces, such as vibration and impact.

[0023] See Figure 7The locking protrusion 18 is a slope with the inclined surface facing forward. The inclination angle of the slope is in the range of 15°-60°, so that the button 4 can achieve a smooth transition through the slope guidance during the locking and unlocking process with the button locking hole 8 of the handle 2.

[0024] When button 4 moves towards the button locking hole 8 of handle 2 to lock, the 15°-60° slope provides a clear guide for button 4. This slope acts like a guide ramp, allowing button 4 to gradually slide into the locking hole, avoiding problems such as jamming or collision when button 4 enters the locking hole, making the locking action smoother and easier.

[0025] See Figure 7 The button 4 has a tactile bulge 19 on its top. The tactile bulge 19 is a triangular prism with a height range of 1mm to 5mm. It is used to provide tactile cues to the user when operating the button 4, so that the user can perceive the position of the button 4 and operate it.

[0026] The height range of 1mm to 5mm provides sufficient protrusion for the indicator bump 19, allowing the user to clearly feel its presence when their finger touches the button 4. This distinct tactile difference contrasts with the smooth surface surrounding the button 4, enabling the user to perceive the button 4's location by touch without needing to look directly at it.

[0027] The first torsion spring 16 and the second torsion spring 9 are both helical springs. The wire diameter of the first torsion spring 16 is in the range of 0.5mm - 2mm, and the wire diameter of the second torsion spring 9 is in the range of 0.3mm - 1.5mm.

[0028] The structure of a coil spring means that the elastic force of a torsion spring is closely related to parameters such as wire diameter, number of coils, and spring diameter. The wire diameter for the first torsion spring 16 is in the range of 0.5mm - 2mm, and the wire diameter for the second torsion spring 9 is in the range of 0.3mm - 1.5mm. By properly selecting the wire diameter and combining it with other parameters, the elastic force generated by the torsion spring can be precisely controlled.

[0029] Handle fastening hole 5: Fastens handle 2 and limits the wobbling position of handle 2.

[0030] Second torsion spring limiting hole 7: limits the rotational position of the second torsion spring 9. Button locking hole 8: locking hole that limits the opening of handle 2 after the structure is closed.

[0031] Second torsion spring placement slot 6; place second torsion spring 9, restricting the position of second torsion spring 9.

[0032] Button fastening hole 13: Insert the flip-out shaft pin 14 to fasten the button 4 so that it rotates in the designated position.

[0033] Base fastening hole 11; insert fastener 15 to fasten base 3.

[0034] Positioning column 10: Installation position of positioning base 3.

[0035] First torsion spring placement slot 12: Positions and limits the position of the first torsion spring 16.

[0036] Flipped pin hole 17: Restricts the movement of fastening button 4 to a specified position.

[0037] Positioning protrusion 18: Restricts the position of handle 2.

[0038] Flip-out pin 14: Secures button 4 to base 3, limiting the movement of button 4.

[0039] First torsion spring 16: applies elastic force to button 4.

[0040] Second torsion spring 9: applies elastic force to handle 2 up and down.

[0041] Structural opening principle: Opening mechanism: Press button 4 → the locking protrusion 18 disengages from the button locking hole 8 of handle 2 → the second torsion spring 9 releases its elasticity → handle 2 pops out → push the frame 20 to move, completing the unlocking. The beveled design ensures smooth unlocking without any jamming.

[0042] Closing the structure: Press handle 2 → Handle 2 engages with the frame 20 → Continue pressing handle 2 → Handle 2 pushes button 4 → The locking protrusion 18 slides into the button locking hole 8 (guided by an inclined surface) → Button 4 locks handle 2 under the action of the first torsion spring 16, completing the closure. The entire process can be operated with one hand, and the prompt protrusion 19 provides tactile feedback.

[0043] Assembly method: 1. Button 4 is inserted into base 3.

[0044] 2. The torsion spring is installed in the middle of button 4.

[0045] 3. Insert the flip-out pin 14, and fasten the button 4 and the first torsion spring 16 onto the base 3.
