Description

Locking device lock mechanism

The present invention relates to a lock structure of a switch device, and particularly relates to a lock structure for loading and unloading an operation part body and a wiring module of a switch device, and particularly relates to a lock structure with good operation and good overall structure. .

It is a well-known technique used in motors, electronics, and automatic control systems to allow an operator to operate a machine or a power on/off state switch or switch indicating device.

Such a switching device, such as the Chinese Patent No. CN 101777446 B "Parts Installation Structure" patent, mainly uses a support body to combine a button (which is an operation portion) and a switch (which is a wiring module); the support body is provided with a through hole For accommodating a button, an annular rotating body is pivoted on the through hole of the support body, and a rotating portion is arranged on the ring body of the rotating body, and a rod protrudes around the rotating body and protrudes into the protection portion on one side of the supporting body. The rod can drive the convex portion of the rotating body to buckle the groove portion of the outer peripheral wall of the button to form a lock, and the button and the support body are combined, and the engaging portion of the rod end and the engaging portion in the protection portion are engaged with each other to position the rod. The engaging portion of the lever can be disengaged from the engaging portion of the protecting portion, and the rod is driven to reversely move the convex portion of the rotating body, and the buttoning of the button groove portion is released to form an unlocking to release the button. In addition, the bottom of the support body is provided with clamping claws for clamping the switch, so that the button can open and close the switch.

However, when the engaging portion of the lever is engaged or disengaged from the engaging portion of the protecting portion, the lever needs to be pulled up and down, and when the lever is pulled up by an external force, the upper portion is The action of the lower pulling is directly transmitted to the inside of the support body via the rod, which easily affects the joint and operational relationship between the support body and the rotating body, and the switching device is prone to a situation in which the opening and closing process is stuck. Moreover, when the rod is pulled up and down, stress concentration occurs in the joint between the swinging rod and the non-swinging rotating body, which directly affects the design and manufacturing conditions of the rotating body and the rod. . For example, if the structure or material of the rotating body or the rod is designed to be soft, the free elastic property of the rod is improved, and although the engaging portion of the rod can be easily and labor-savingly engaged or disengaged from the engaging portion of the protecting portion, Therefore, it is easy to be accidentally touched by an external force, and the engaging portion of the rod is loosened from the engaging portion of the protection portion, resulting in a poor locking function. On the other hand, if the material or structural strength of the rotating body and the rod is increased, the chance of the rod being loosened by the external force may be reduced, but the engaging portion for operating the rod is engaged or disengaged from the engaging portion of the protecting portion. The problem, and the material or structure of the rod is enhanced, usually reducing the elastic deformation ability at the same time, so that the joint between the rod and the rotating body is more likely to cause the rotating body to follow the rod up and down during the pulling operation. In the case of the misalignment, the above-mentioned opening and closing process is stuck, and even the joint is broken due to the problem of stress concentration.

In order to improve the above problem, Taiwan applied for the patent application No. 103,113,953, "Twisting Combination Structure of Switching Device", which discloses a technique of combining a body and a wiring module by using a connecting base.

And the insert block of the pulling body is fastened to the groove of the body to form a lock; if the pressing portion is pressed in the locked state, the deformation and displacement of the restricting portion can be pushed, and the restricting portion is released from the restriction on the ridge. The block of the trigger body is driven to reverse displacement, and the latching of the body groove is released to form an unlock to release the body. In addition, the bottom of the connecting seat is provided with a fastening portion for fastening a plurality of parallel connection modules, and the operation unit drives the wiring assembly to control the open circuit or the passage state of the electrical contacts.

In the embodiment taken, one side of the upper region 13 (or the top) of the connecting seat 1 protrudes with an arm 14 and a restricting portion 15 formed on the arm 14, and a side wall 16 is provided on one side of the bottom surface of the arm 14, and the restricting portion 15 is defined by The bottom surface of the arm 14 protrudes toward the bottom of the connecting base 1 (or the fastening portion 12), and a slope portion 151 and a blocking wall 152 are respectively disposed on opposite sides of the limiting portion 15, and the blocking wall 152 corresponds to the side wall 16, and A fastening groove 17 is formed between the retaining wall and the side wall, and a supporting portion 153 is formed between the starting end of the inclined section 151 and the blocking wall 152.

Referring to Figures 1, 3 and 4, the trigger body 2 is combined in the upper region 13 of the connector block 1. The trigger body 2 includes an annular portion 21 and a trigger portion projecting from the outer peripheral wall of the annular portion 21. And a mouth portion 24 formed on the pulling portion 23, the annular portion 21 is provided with a through hole 20 and a plurality of inserts 22 formed on the inner wall of the through hole 20 for receiving a lever member 25 .

2 and 3, in a preferred embodiment, a middle portion of the lever member 25 is provided with a point portion 251 which is connected to the inner wall of the central portion of the mouth portion 24. a ridge portion 252 and a pressing portion 253, the urging portion 253 is a lever fulcrum, and a lever structure is formed with respect to the ridge portion 252; in the embodiment, the pulsing portion 23 of the pulling body 2, The mouth portion 24 and the lever member 25 can be integrally formed of a plastic material, so that the fulcrum portion 251 has an elastic twisting ability as a swinging fulcrum of the lever member 25, so that the lever member 25 can have the fulcrum portion 251 as a fulcrum, so that both ends thereof The pressing portion 253 and the ridge portion 252 generate a relatively reverse oscillating action. The ridge portion 252 and the pressing portion 253 respectively have an elastic movement range, so that the pressing portion 253 can cause the lever member 25 to pivot with the fulcrum portion 251 as a fulcrum when the person presses the lever portion, and the ridge portion 252 is pulled by the lever type. Swing in the opposite direction.

1 and 2 show that when the pulling body 2 is combined in the connecting seat 1 and the pulling portion 23 and the arm 14 are in a non-corresponding position, the groove 33 of the operating portion body 3 is allowed to pass through the annular portion 21 through hole 20 The insert 22 in the middle allows the body 3 to be combined with the connecting seat 1; at this time, the pulling body 2 is in the unlocking position (or the unmounted position), and is defined as the first position.

5 and 6 show that the pulling portion 23 of the operating trigger body 2 is displaced to the region of the arm 14 close to the side wall 16, so that when the pulling portion 23 and the arm 14 form a corresponding type (or alignment position), the ring is driven. The insert 22 of the portion 21 is moved from the groove 33 of the body 3 into the end groove 34 (please refer to Fig. 1); at this time, the pulling body 2 is in the locked position (or fixed mounting position) and is defined as the second position.

Referring to Figures 1, 2, 5 and 6, when the person operates the trigger portion 23 to move from the first position to the second position, the ridge 252 slides along the inclined portion 151 and the supporting portion 153, causing the lever member 25 to The restricting portion 15 is convexly slid (or the bottom of the connecting seat 1) to elastically oscillate the ridge portion 252, so that the ridge portion 252 directly elastically passes over the convex portion (the supporting portion 153) of the restricting portion 15, and elastically buckles into the retaining wall 152 and the side wall. 16 is defined in the fastening groove 17; therefore, the side of the ridge 252 is elastically blocked by the blocking wall 152, and the pulling portion 23 cannot be operated toward the unlocking direction, and is located on the other side of the ridge 252. The edge of the trigger portion 23 is also blocked by the side wall 16, so that the ridge portion 252 is restrained by the buckle groove 17 to form a lock.

Referring to Fig. 7, in the state in which the above-mentioned locking is formed, when the person presses the pressing portion 253 in the direction of the arm 14, the pressing portion 253 can be urged with the fulcrum portion 251 as a fulcrum to drive the ridge portion 252 toward the restricting portion 15 Elastically swinging in the direction of the bottom (or the bottom of the connecting seat 1), causing the ridge 252 to disengage from the buckle of the locking groove 17 beyond the restricting portion 15; the triggering portion 23 can be pushed from the second position to the first position (such as the first And FIG. 2), unlocking (or releasing the state); at the same time, the pulling body 2 drives the insert 22 to move backward from the end groove 34 to the groove 33, and the insert 22 is released from the groove 33 of the body 3. The buckle body is used to make the body 3 and the connector 1 form a detachable type.

It can be understood that when the ridge portion 252 is elastically oscillated in the protruding direction of the restricting portion 15 in the engaging groove 17 (as shown in FIG. 7), since the ridge portion 252 is swayed along the arc path with the fulcrum portion 251 as a fulcrum, Therefore, when the ridge portion 252 gradually moves toward the protruding direction of the restricting portion 15, there is a tendency to urge the ridge portion 252 to gradually push toward the retaining wall 152. At this time, the ridge portion 252 is blocked by the blocking wall 152 in the opposite direction. A slight elastic bending phenomenon is generated in the direction of the side wall 16; when the ridge portion 252 just exceeds the protruding height of the blocking wall 152, the ridge portion 252 immediately releases the elastic force, and the inclined portion 151 (or the fulcrum portion 251) toward the restricting portion 15 The direction is springed so that the ridge 252 can elastically abut against the retaining portion 153 over the retaining wall 152; thus, the ridge 252 can be effectively prevented, and the elastic buckle is again buckled when the pressing force of the pressing pressing portion 253 is relaxed. The fastener groove 17 defined between the retaining wall 152 and the side wall 16 facilitates easy operation of the trigger portion 23 from the second position to the first position.

By the structure of the limiting portion 15 of the connecting seat 1 and the lever member 25 of the pulling body 2, as long as the single member of the lever member 25 is pushed, the unlocking action of the locking structure can be completed, compared with the conventional switching device. When the lock is unlocked, the lock structure of the two components must be pushed and displaced at the same time, which is obviously labor-saving; and, since the arm 14 of the joint 1 is operated, it is not necessary to expose the Taiwan patent case to open the mouth. The opening and closing of the lock is achieved, so the overall structure is more complete. Accordingly, the problem of the laborious operation and the poor sealing feeling of the overall structure may be caused when the conventional switch device assembly is unloaded.

In addition to this, the fulcrum portion 251 of the lever member 25 is provided between the pressing portion 253 and the ridge portion 252. In a possible embodiment, the fulcrum portion 251 may also be disposed on the lever member 25 at a position adjacent to the ridge portion 252 such that the distance from the pressing portion 253 to the fulcrum portion 251 is greater than the distance from the ridge portion 252 to the fulcrum portion 251. In order to improve the labor saving effect of operating the lever member 25.

In another possible embodiment, the fulcrum portion 251 may also be disposed on the lever member 25 adjacent to the pressing portion 253 such that the distance from the pressing portion 253 to the fulcrum portion 251 is smaller than the ridge portion 252 to the fulcrum portion 251. The distance is increased to increase the angle at which the lever member 25 swings the ridge portion 252, so that the length of the ridge portion 252 and the depth of the buckle groove 17 can be increased, thereby increasing the stability of the ridge portion 252 in the fastening groove 17.

The above description of the present invention and the specific embodiments are merely illustrative and not exhaustive of all possible variations.
