Description

Technical Field

[0001] The present invention relates to an improved structure of a locking device; in particular, it relates to a technology of arranging an operating part combined with an elastic member on an actuating body to improve the operating smoothness (or convenience) of the existing structure. Background Art

[0002] The application of a locking device or a similar device installed on the cover structure of a computer / electronic device, server chassis, etc., to provide a person with the ability to open / close the computer / electronic device or control the cover structure to lock and close the chassis body to prevent the internal components or parts of the chassis from being exposed, or to operate the cover structure to open so that the person can configure, repair, etc. the internal components of the chassis, is already a prior art.

[0003] A type of latch device generally includes a housing, an actuating handle and a sliding plate; a push button is provided at one end of the housing. The actuating handle has a pivot end that cooperates with a spring and is pivoted to the other end of the housing; the other end of the actuating handle is pivoted to a connecting rod, and a protrusion is provided at the other end of the actuating handle to allow the protrusion to be embedded in the push button to form a locked state. When a person operates the push button to release the protrusion, the spring pushes the actuating handle to open, driving the sliding plate to move and the connecting rod to prop up the actuating handle.

[0004] The prior art has also disclosed a latch device including a housing, an actuating handle and a sliding plate. This latch device includes a housing and a combination of an actuating body, a linkage frame and a sliding body mounted on the housing. The actuating body has a free end and a pivot end that cooperates with an elastic device to pivotally connect the housing, so that the actuating body can form a reciprocating motion; the free end of the actuating body is provided with an opening area for setting a swingable operating part. And, the linkage frame has a first end pivotally connected to the free end (or operating part) of the actuating body and a second end connected to the sliding body; when a person presses the operating part (swings), the actuating body is allowed to move from a closed position to an open position, thereby driving the linkage frame and the sliding body to move.

[0005] One problem with the combination of existing latch devices in terms of structure and operational application is that the direction in which the operator presses the operating portion is opposite to the direction in which the actuating handle (or actuating body) swings open, which relatively affects the smoothness or convenience of the operation, which is not what we expect.

[0006] Representatively speaking, these references show the skills in structural combination design and application of latch devices or similar locking mechanisms; if the structural combination of the latch (or lock) device and the actuating handle is redesigned to make its structure different from the existing one, its usage form can be changed from the old method; in essence, its application effect will also be increased.

[0007] We have found that an ideal latching device or locking device must be able to overcome or improve the above-mentioned issues and should include the following design considerations: 1. Under the condition that the structure has smooth operation (or smoothness), the structural form of the existing structure in which the movement direction of the operating part is opposite to the opening direction must be improved.

[0008] 2. Further consideration is given to providing an improved structure, which is beneficial to assisting the actuating body (and / or linkage frame, sliding body) to move in the opening direction (smoothly) during the operation process.

[0009] However, these topics are not taught or specifically disclosed in the above-mentioned references. Summary of the invention

[0010] The main purpose of the present invention is to provide an improved structure of a locking device, including a housing and an actuating body, a linkage frame, and a sliding body mounted on the housing. The actuating body has a free end and a pivot end that cooperates with an elastic device to pivotally connect the housing, so that the actuating body can form a reciprocating motion; the free end of the actuating body is provided with two cantilevers and an opening area between the cantilevers, and the opening area is used to set an operating part and an auxiliary operating part to generate an elastic member that reciprocates in the axial direction of the actuating body. In addition, the linkage frame has a first end pivotally connected to the free end (or operating part) of the actuating body and a second end connected to the sliding body; and when a person pulls (and pushes) the operating part to move, the auxiliary actuating body moves from a closed position to an open position, thereby driving the linkage frame and the sliding body to move, thereby improving the situation in which the movement direction of the operating part of the existing structure is opposite to the opening direction, affecting the smoothness (or convenience) of the operation.

[0011] According to the improved structure of the locking device of the present invention, the operating part includes a base for operation, a main area and a secondary area located at both ends of the base; the operating part or the main area is provided with a secondary assembly part (a concave hole structure or a convex part structure) for assembling or accommodating the elastic member; and the secondary area is provided with a positioning part (a hook-shaped structure). Corresponding to the positioning part, the shell is formed with a secondary positioning part (a notch structure); when the actuating body is in the closed position (or the actuating body is closed in the shell), the positioning part is allowed to be combined with the secondary positioning part, so that the actuating body is buckled or embedded on the shell to form a fixed shape.

[0019] See also Figure 1 , 2 and Figure 3 The improved structure of the lock device of the present invention comprises a combination of a housing, an actuator, a linkage frame, and a sliding body, which are generally represented by reference numbers 10, 20, 30, and 40. The housing 10 has a bottom wall 11, two side walls 12 extending in a direction parallel to the axis of the housing 10, a main end wall 13 and a secondary end wall 14 connected to the side walls 12 and perpendicular to the axis of the housing 10, and together define an open chamber 15 of the housing 10 to accommodate the actuator 20, the linkage frame 30, and the sliding body 40.

[0020] In the following description, if upper, above, lower, below, right, left, side, etc. are mentioned, the direction shown in the figure is used as a reference direction.

[0021] The figure shows that the side wall 12 of the housing 10 is provided with an elongated hole 16, the main end wall 13 is formed with a notch 18 structure, and the secondary end wall 14 is provided with a secondary positioning portion 19 with a notch structure. In addition, the inner edge of the side wall 12 of the housing 10 is provided with a flange structure 12a, which can assist in regulating the sliding body 40 to form a smooth sliding movement in the chamber 15 of the housing 10.

[0022] In the embodiment adopted, the actuator 20 is a plate structure, defining an axial direction X, a free end 21 and a pivot end 22 of the housing 10 pivotally connected to the elastic device 50, so that the actuator 20 can form a reciprocating (swinging) motion (or simple harmonic motion).

[0023] In detail, the pivot end 22 of the actuating body 20 is provided with an axial connection portion 23 and recesses 24 located at both ends of the axial connection portion 23, which are used to assemble (or position) the elastic device 50. The elastic device 50 is in the form of a torsion spring, and has a ring portion 53, a first section 51 connected to the ring portion 53, a second section 52, and an extension section 54 (perpendicularly) connected to the second section 52. In addition, the axial connection portion 23 is combined with a shaft 70, and the shaft 70 is inserted into the ring portion 53 of the elastic device 50 and the shaft hole 17 formed on the side wall 12 of the housing 10; the first section 51 of the elastic device 50 is against the bottom wall 11 of the housing 10, and the second section 52 is against the actuating body 20 (or the recess 24), so that the actuating body 20 is formed with the shaft 70 (and / or the shaft hole 17, the axial connection portion 23) as the rotation center, and forms a reciprocating (or swinging) state.

[0024] The figure also depicts that the free end 21 of the actuator 20 is provided with two (parallel) protruding cantilevers 25 and an opening area 26 located between the two cantilevers 25. The cantilevers 25 are formed with a groove 25a to facilitate the operation of a person (fingers). In addition, the inner edge of the cantilever 25 is parallel to the axis direction X of the actuator 20 and is provided with a track 95; the free end 21 or the tail of the cantilever 25 is provided with a pin hole 27, corresponding to the form of a pivot pin 77.

[0025] In the embodiment, the actuating body 20 is provided with an assembly portion 96 in the area inside the opening area 26 (or away from the tail of the cantilever 25) for assembling (or positioning) an elastic member 55; the assembly portion 96 may be formed in the form of a convex pile or a concave hole structure. In addition, the opening area 26 is used to set the operating portion 80 and an elastic member 55 that assists the operating portion 80 to generate reciprocating motion in the axial direction X of the actuating body 20.

[0026] In detail, the operating part 80 includes a base 83 for operation, a main area 81 and a secondary area 82 located at both ends of the base 83; the base 83 is a concave structure (and / or grooves 87 connecting the concave structures are formed on both sides of the base 83, corresponding to the groove 25a of the cantilever 25), so as to facilitate the personnel to pull (or push) the operating part 80 to move. Corresponding to the track 95 of the cantilever 25, the side of the operating part 80 is provided with a secondary track 85. Combined with the above-mentioned track 95, the auxiliary operating part 80 can move back and forth (linearly) more smoothly along the axis direction X, and ensure that the operating part 80 can be located in the correct position of the opening area 26 (or between the two cantilevers 25) during the movement of the actuator 20.

[0027] In addition, the operating portion 80 or the main area 81 is provided with a sub-assembly portion 86 (a recessed structure or a convex structure) for combining or accommodating the elastic member 55; the sub-area 82 is provided with a positioning portion 84 in a hook-shaped structure; when the actuator 20 is in the closed position (or the actuator 20 is closed in the shell 10), the positioning portion 84 is allowed to combine (or lock) with the sub-positioning portion 19, so that the actuator 20 (or the operating portion 80) is embedded or snapped on the shell 10 to form a fixed shape.

[0028] In a feasible embodiment, the elastic member 55 is in the form of a coil spring (or other elastic structure), having a first area 56 positioned (or combined) on the assembly portion 96 and a second area 58 accommodated (or pressed) in the secondary assembly portion 86, so as to achieve the function of enabling the operating portion 80 to generate reciprocating motion and keeping the positioning portion 84 and the secondary positioning portion 19 locked.

[0029] The figure shows that the linkage frame 30 is defined by a first end 31 and a second end 32; the first end 31 is provided with a pin hole 37, which is pivotally connected to the above-mentioned shaft pin 77, so that the first end 31 of the linkage frame 30 forms a free end 21 of the pivotally connected actuating body 20 in a freely rotatable (or swinging) state.

[0030] In the embodiment, the second end 32 of the linkage frame 30 is provided with a shaft connection portion 33 for pivoting a shaft column 73, so that the second end 32 of the linkage frame 30 can move or rotate freely. In addition, the shaft column 73 combines the shaft connection portion 33 of the linkage frame 30 and also pivots the sliding body 40.

[0031] The figure depicts a sliding body 40 in a plate structure, which is mounted on the housing 10 (or the chamber 15) to form a freely movable form. The sliding body 40 is defined with a main end 43 and a secondary end 44; between the main end 43 and the secondary end 44, a combination part 41 in a convex plate structure and an axial hole 42 formed on the combination part 41 are provided.

[0032] Therefore, the shaft column 73 combines the shaft connection portion 33 of the linkage frame 30 and the shaft hole 42 of the combination portion 41 of the sliding body 40; and the shaft column 73 (both ends) is pivotally connected to the long hole 16 of the housing 10. When a person operates (or pulls) the operating portion 80 to move along the axial direction X, the actuating body 20 is allowed to move from a closed position to an open position, thereby driving the linkage frame 30 to move, and the shaft column 73 moves along the long hole 16, driving the sliding body 40 to move; improving the situation in which the operation (pressing) direction of the existing structure is opposite to the opening direction, affecting the smoothness (or convenience) of the operation.

[0033] The closed position refers to the position where the actuating body 20 is retracted in the housing 10 (or the chamber 15 ); the open position refers to the position where the actuating body 20 (or the free end 21 ) moves away from the housing 10 .

[0034] It is understood that the opening or closing movement range (or angle) of the actuator 20 in the shell 10 can be controlled by the distance between the axle connection portion 33 of the linkage frame 30 and the pin hole 37, the movement distance of the sliding body 40 (and / or the length of the elongated hole 16, the movement distance of the shaft column 73).

[0035] Please refer to Figure 3 The actuating body 20 is provided with a recess 28 and a limiting portion 29 formed on the recess 28 between the free end 21 and the pivot end 22; and the recess 28 is equipped with a locking mechanism 60. The locking mechanism 60 includes a combination of a rotating body 61 received in the recess 28 and a locking plate 62 pivotally connected to the rotating body 61.

[0036] The figure depicts that the swivel 61 is formed with a secondary limiting portion 63 and a base portion 64 in a convex shaft structure; and the lock plate 62 can be (integrally) combined with a wing portion 66, and the wing portion 66 has a connecting portion 65 in a hole-like structure. In addition, after the lock mechanism 60 is installed in the recess 28, the base portion 64 (protruding) is allowed to pivotally connect the connecting portion 65; when a person operates the swivel 61 to rotate, the limiting portion 29 of the actuator 20 blocks the secondary limiting portion 63, so as to regulate the rotation angle or rotation range of the swivel 61.

[0037] In the embodiment adopted, corresponding to the structure of the lock mechanism 60, the linkage frame 30 is provided with a locking hole 36 between the first end 31 and the second end 32 to allow the locking plate 62 (or the wing 66) to pass through. The locking hole 36 is formed by forming an annular protrusion 39 on a through hole 38.

[0038] It is understood that when the lock mechanism 60 is in the locked state, the wing 66 is clamped on the locking hole 36 (or the annular protrusion 39), so that the actuator 20, the linkage frame 30 and the sliding body 40 are closed and fixed to the housing 10 (or the chamber 15). When a person rotates the swivel 61, the locked state of the wing 66 and the locking hole 36 of the linkage frame 30 is released, and the unlocked state is formed.

[0039] Figure 4 The figure shows that the positioning portion 84 of the operating portion 80 is combined or snapped into the auxiliary positioning portion 19 of the shell 10, thereby keeping the actuator 20, the linkage frame 30 and the sliding body 40 closed in the shell 10 (or the chamber 15), and making the elastic device 50 form a state of accumulating energy.

[0040] Please refer to Figure 5 When a person (finger) pulls the operating part 80 toward the left side of the figure through the base 83 and moves it along the axis direction X, the operating part 80 pushes the elastic member 55 to store energy, and the positioning part 84 leaves the auxiliary positioning part 19 of the housing 10. Therefore, the elastic device 50 releases the stored energy, pushes the actuating body 20 to move toward the open position, and drives the linkage frame 30 to move; for example, Figure 6 The situation depicted.

[0041] The figure also shows that the actuating body 20 causes the second end 32 of the linkage frame 30 to drive the shaft column 73 to move along the elongated hole 16 and causes the sliding body 40 to move between the main end wall 13 (or the notch 18 thereof) and the secondary end wall 14 of the housing 10 .

[0042] It should be noted that the direction of the applied force (or acting force) generated when a person pulls the operating part 80 to move along the axial direction X takes into account the following issues: 1. The direction of the applied force (or acting force) is the same as the (horizontal) force direction of the actuating body 20 moving in the opening direction, thereby facilitating the opening (or opening) movement of the actuating body 20 (and / or the linkage frame 30, the sliding body 40).

[0043] 2. The base 83 of the operating portion 80 forms a concave structure to conform to human operating ergonomics (or the pulling / force of a person's fingers), and also facilitates the opening (or unlocking) movement of the actuator 20 (and / or the linkage frame 30).

[0044] In a feasible embodiment, when the actuator 20 is closed in the housing 10, a portion of the main end 43 of the sliding body 40 protrudes out of the notch 18 of the main end wall 13 of the housing 10. When the actuator 20 is in the open position, the secondary end 44 of the sliding body 40 is relatively driven to protrude out of the secondary end wall 14 of the housing 10.

[0045] Typically, the improved structure of the locking device has the following advantages compared to the prior art: 1. The housing 10, the actuating body 20, the linkage frame 30, the sliding body 40 and the related component structures have been redesigned. For example, the free end 21 of the actuating body 20 is provided with two cantilevers 25 and an opening area 26, which are equipped with an operating part 80; the cantilever 25 is provided with a track 95, and the opening area 26 is provided with an assembly part 96, which is used to combine or position the elastic member 55; a secondary track 85 is provided to cooperate with the operating part 80 to make the operating part 80 move along the axial direction X, and the operating part 80 is provided with a secondary assembly part 86 for accommodating the elastic member 55; the secondary area 82 of the operating part 80 is provided with a positioning part 84, which is engaged with the secondary positioning part 19 of the secondary end wall 14 of the housing 10 to control the actuating body 20, the linkage frame 30 and other components to close to the housing 10 or allow the actuating body 20 to drive the linkage frame 30, the sliding body 40 and other parts to move, which is obviously different from the conventional users, and also changes the structure or combination relationship of the existing structural latch device, so that its use and operation form are different from the old method.

[0046] 2. In particular, under the condition that the structure has smooth operation (or smoothness), the matching structure of the actuating body 20 and the operating part 80 significantly improves the structural form of the existing structure in which the operating direction is opposite to the opening direction. In addition, it further provides a situation that is conducive to achieving the function of assisting the actuating body 20 (and / or the linkage frame 30, the sliding body 40) to move (smoothly) in the opening direction during the operation process and the convenience of operation.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
