Description

Technical Field

[0001] The invention relates to a locking mechanism of a pop-up socket and belongs to the technical field of sockets. Background Art

[0002] Sometimes a pop-up socket structure is used in floor sockets and desktop sockets. The pop-up socket includes a box body, a locking mechanism and a jump frame mechanism. Usually, the jump frame mechanism is locked in the box body by the locking mechanism. When it is necessary to connect electricity, the jump frame mechanism is unlocked by operating the locking mechanism. The jump frame mechanism pops up upward under the action of elastic force, so that the socket module on it is exposed. An existing locking mechanism includes a lock bar and a control button. The lock bar is movably mounted on the face frame of the box body. The control button and the lock bar are matched by the inclined surface. When the control button is pressed downward, the lateral pushing action of the inclined surface drives the lock bar to move and separate from the jump frame mechanism to unlock the jump frame mechanism. The problem with this locking mechanism is that due to the limited movable travel of the control button, it can only drive the lock bar to move within a relatively small travel. In actual use, the lock bar may not be completely and effectively separated from the jump frame mechanism when unlocking, thereby affecting the smooth pop-up of the pop-up mechanism. Summary of the invention

[0003] In this regard, the present invention aims to provide a locking mechanism for a pop-up socket with a reasonable structure. Through the setting of a stroke amplification lever, the control button only needs to move a small stroke to control the larger stroke movement of the lock bar, thereby avoiding the problem that the lock bar cannot be completely separated from the jump frame mechanism when unlocking due to the small active stroke of the control button.

[0004] The technical solution for achieving the purpose of the present invention is:

[0005] A locking mechanism of a pop-up socket comprises a face frame, a lock bar movably arranged at the bottom of the face frame, a first elastic component providing locking elastic force for the lock bar, a control button for controlling the unlocking of the lock bar and a stroke amplification lever arranged between the control button and the lock bar, wherein the face frame is provided with a button hole, the control button is installed in the button hole, a mounting seat is provided at the bottom of the face frame, the stroke amplification lever is rotatably mounted on the mounting seat via a mounting shaft serving as a fulcrum, the stroke amplification lever comprises a power part correspondingly connected to the control button and a resistance part correspondingly connected to the lock bar, the force arm length of the power part is smaller than the force arm length of the resistance part, and when the control button is pressed downward, the lock bar is driven to move in the unlocking direction through the stroke amplification lever and the first elastic component is compressed.

[0006] In the above technical solution, a limiting pressure plate for limiting the installation of the locking strip is fixed to the bottom of the face frame.

[0007] In the above technical solution, the middle part of the lock bar is rotatably installed between the limit pressure plate and the face frame through a pivot shaft, and one end of the lock bar is a locking end and the other end is a driving end, and the driving end is correspondingly connected to the resistance part of the stroke amplification lever.

[0008] In the above technical solution, a driving plate is formed by bending on the locking bar, and the resistance portion abuts against the side surface of the driving plate.

[0009] In the above technical solution, a driving rod is provided at the bottom of the control button, a position on the travel amplification lever corresponding to the bottom end of the driving rod is a slope surface, and the bottom end of the driving rod has an arc angle suitable for contacting the slope surface.

[0010] In the above technical solution, the first elastic component is a helical compression spring, one end of which abuts against the face frame, and the other end of which abuts against the locking bar.

[0011] The above technical solution also includes a second elastic component that provides an upward restoring elastic force for the control button.

[0012] In the above technical solution, the second elastic component is a helical compression spring, one end of which abuts against the mounting seat, and the other end of which abuts against the control button.

[0013] The above technical solution further includes a flexible sealing sheet for closing the gap between the button hole and the control button;

[0014] The flexible sealing sheet includes a key connecting portion located in the key hole and a sealing connecting portion arranged around the key connecting portion, the sealing connecting portion is sealingly connected to the bottom surface of the face frame, and the key connecting portion is sealingly connected to the control key.

[0015] In the above technical solution, the control button includes a button surface cover located on the upper side of the button connecting portion and a button body located on the lower side of the button connecting portion, and the button surface cover is snap-connected to the button body and presses the button connecting portion.

[0016] The present invention has positive effects: a travel amplification lever is provided in the locking mechanism of the present invention, which is used to amplify the active travel of the control button through the travel amplification lever and then act on the lock bar, so that when the jump frame mechanism is unlocked, the lock bar can be driven to produce a larger active travel by pressing the control button, so that the lock bar and the jump frame mechanism can be completely separated, thereby ensuring the effectiveness of unlocking and enabling the jump frame mechanism to pop up smoothly, which has good practicality.

DETAILED DESCRIPTION

[0030] The specific structure of the locking mechanism of the pop-up socket of the present invention is described below in conjunction with the accompanying drawings of the specification:

[0031] A locking mechanism for a pop-up socket, such as Figures 1 to 10 As shown, it includes a face frame 1, a lock bar 2 movably arranged at the bottom of the face frame 1, a first elastic component 3 providing locking elastic force for the lock bar 2, a control button 4 for controlling the unlocking of the lock bar 2 and a stroke amplification lever 5 arranged between the control button 4 and the lock bar 2, the face frame 1 is provided with a button hole 11, the control button 4 is installed in the button hole 11, the bottom of the face frame 1 is provided with a mounting seat 12, the stroke amplification lever 5 is rotatably mounted on the mounting seat 12 through a mounting shaft 51 as a fulcrum, the stroke amplification lever 5 has a power part 52 correspondingly connected to the control button 4 and a resistance part 53 correspondingly connected to the lock bar 2, the force arm length of the power part 52 is smaller than the force arm length of the resistance part 53, when the control button 4 is pressed downward, the lock bar 2 is driven to move in the unlocking direction through the stroke amplification lever 5, and the first Elastic component 3; in the locking mechanism of this embodiment, a stroke amplification lever 5 is provided, which is used to amplify the activity stroke of the control button 4 through the stroke amplification lever 5 and then act on the lock bar 2, so that when the jump frame mechanism (not shown in the figure) is unlocked, the lock bar 2 can be driven to produce a larger activity stroke by pressing the control button 4, so that the lock bar 2 and the jump frame mechanism can be completely separated, thereby ensuring the effectiveness of unlocking and enabling the jump frame mechanism to bounce up smoothly, which has good practicality; specifically, during operation, pressing the control button 4 downwards produces pressure on the power part 52 of the stroke amplification lever 5, so that the stroke amplification lever 5 generates a lateral thrust on the lock bar 2 through the resistance part 53 during the rotation of the stroke amplification lever 5 around the mounting shaft 51, thereby pushing the lock bar 2 to move in the unlocking direction and compressing the first elastic component 3 at the same time. After releasing the pressure applied to the control button 4, the lock bar 2 is movable and reset under the action of the first elastic component 3.

[0032] In a further implementation scheme of this embodiment, a limiting pressure plate 6 for limiting the installation of the locking strip 2 is fixed at the bottom of the face frame 1. The setting of the limiting pressure plate 6 facilitates the limiting installation of the locking strip 2, and the limiting pressure plate 6 is fixed to the face frame 1 with screws.

[0033] In a further implementation of this embodiment, the middle part of the lock bar 2 is rotatably installed between the limit pressure plate 6 and the face frame 1 through the pivot shaft 13, and one end of the lock bar 2 is a locking end 21, and the other end is a driving end 22, and the driving end 22 is correspondingly connected to the resistance part 53 of the travel amplification lever 5; during the unlocking operation, by pressing the control button 2 downward to rotate the travel amplification lever 5, the resistance part 53 on the travel amplification lever 5 generates a force on the driving end 22 to rotate the lock bar 2 around the pivot shaft 13, and then the lock bar 2 is released by separating from the jumping mechanism through the locking end 21. As a modified implementation scheme, the lock bar 2 can also be movably arranged between the limit pressure plate 6 and the face frame 1, and the movable direction of the lock bar 2 is the direction of approaching and moving away from the jumping frame mechanism.

[0034] As a preferred solution of this embodiment, a driving plate 221 is bent on the locking bar 2, and the resistance portion 53 abuts against the side of the driving plate 221. By providing the driving plate 221, the contact surface between the resistance portion 53 and the locking bar 2 is increased, thereby ensuring the effectiveness of force transmission between the two.

[0035] In a further solution of this embodiment, a driving rod 41 is provided at the bottom of the control button 4, and a position on the stroke amplification lever 5 corresponding to the bottom end of the driving rod 41 is a slope surface 54, and the bottom end of the driving rod 41 has an arc angle 411 suitable for contacting with the slope surface 54; in this solution, the arc angle 411 of the driving rod 41 contacts and cooperates with the slope surface 54 on the stroke amplification lever 5, so that the relative movement of the two during the unlocking and locking process is smoother and jamming is avoided.

[0036] In a further solution of the present embodiment, the first elastic component 3 is a helical compression spring, one end of which abuts against the face frame 1, and the other end abuts against the locking bar 2. In order to effectively position the first elastic component 3 and prevent the first elastic component 3 from shifting and causing the restoration elastic force of the locking bar 2 to fail, limiting grooves 23 can be provided at the positions where the first elastic component 3 is connected on the face frame 1 and the locking bar 2, and the corresponding ends of the first elastic component 3 are inserted into the limiting grooves 23 to achieve positioning.

[0037] As a further improvement of this embodiment, the locking mechanism also includes a second elastic component 7 for providing an upward reset elastic force for the control button 4; the second elastic component 7 is a spiral compression spring, one end of which abuts against the mounting seat 12, and the other end abuts against the control button 4, and the second elastic component 7 provides assistance for the upward reset of the control button 4.

[0038] In this embodiment, in order to enhance the waterproof and dustproof effect at the key hole 11, the locking mechanism also includes a flexible sealing sheet 8 that closes the gap between the key hole 11 and the control key 4; the flexible sealing sheet 8 includes a key connection portion 81 in the key hole 11 and a sealing connection portion 82 arranged around the key connection portion 81, the sealing connection portion 82 is sealed and connected to the bottom surface of the face frame 1, and the key connection portion 81 is sealed and connected to the control key 4; the provision of the flexible sealing sheet 8 closes the gap between the control key 4 and the key hole 11, thereby improving the sealing performance of this part. The flexible sealing sheet 8 is preferably made of soft rubber material such as rubber and silicone, and the sealing connection portion 82 can be pressed against the bottom surface of the face frame 1 through the mounting seat, or can be bonded to the bottom surface of the face frame 1 by glue.

[0039] Furthermore, the control button 4 includes a button surface cover 42 located on the upper side of the button connecting part 81 and a button body 43 located on the lower side of the button connecting part 81 (the driving rod 41 is arranged at the bottom of the button body 43), and the button surface cover 42 is connected to the button body 43 by snapping and pressing the button connecting part 81; in this embodiment, the button surface cover 42 and the button body 43 are assembled by split snapping and pressing the button connecting part 81 to achieve a sealed connection.

[0040] See also Figure 5 and Figures 10 to 12As shown, in this embodiment, a buckle 421 is provided on the button cover 42, and a perforation 811 and a buckle hole structure 430 are respectively provided on the button connecting portion 81 and the button body 43 at positions corresponding to the buckle 421. The buckle 421 passes through the perforation 811 and is engaged with the buckle hole structure 430. The buckle hole structure 430 includes a through hole 431 formed on the button body 43 and an elastic tooth 432 connected to the peripheral wall of the through hole 431 and extending downward. A plurality of circumferentially distributed elastic teeth 432 enclose a radially retractable elastic tube 433. The lower end of the buckle 421 has a limit stop 422. After passing through the through hole 431 and the elastic tube 433, the limit stop 422 forms a stopper cooperation with the lower end of the elastic tooth 432. When the limit stop 422 passes through the elastic tube 433, the elastic teeth 432 are pushed outward. After passing through, the elastic teeth 432 shrink inward and the bottom ends thereof abut against and cooperate with the limit stop 422 to thereby achieve a reliable connection, and realize the snap connection between the button body 43 and the button cover 42 while pressing the button connecting portion 81. More specifically, the outer portion of the elastic tube 433 is a conical structure that is thick at the top and thin at the bottom, and the conical structure is suitable for being sleeved with the upper end of the second elastic component 7 that provides an upward reset elastic force for the control button 2. By sleeve-fitting the upper end of the second elastic component 7 with the outer portion of the elastic tube 433, not only the installation and positioning of the second elastic component 7 is achieved, but also the elastic tube 433 can be tightened by the second elastic component 7, thereby enhancing the reliability of the snap connection between the buckle 421 and the buckle hole structure 430.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
