Description

knob

The present invention relates to a knob.

The conventional knob can be screwed on a screw, the screw can be fixed on a first part and can movably pass through a second part, and the screw can be pressed against the first part by rotating the knob to move relative to the screw. The two parts are relatively close to the first part, so that the tightness of the first part and the second part can be adjusted.

However, the aforementioned adjustment method is easily affected by the operating force of the operator. For example, if the operating force is too large, the first part, the second part or the object sandwiched between the first part and the second part may be easily damaged; if the operating force is too small, the first part may be damaged. There are problems such as insufficient urgency with the second component and poor assembly stability, which need to be improved urgently.

Therefore, it is necessary to provide a novel and progressive knob to solve the above problems.

The main purpose of the present invention is to provide a knob, which has a prompting effect and can provide an appropriate resistance strength.

In order to achieve the above object, the present invention provides a knob, comprising: a casing including at least one reference part; a rotating member defining an axial direction, and is disposed on the casing so as to be relatively movable along the axial direction without relative rotation, It includes a threaded portion for screwing on a screw rod; and an indexing mechanism, which is arranged on the casing so as to interfere with the rotating member in the axial direction, and includes at least one indexing portion; wherein, when the casing rotates, the rotating member is driven to face each other. When the screw moves and abuts against an object, the rotating member axially interferes with the index mechanism and drives at least one index portion to correspond to at least one reference portion.

When the threaded portion 21 is screwed to the screw 2 and the rotating member 20 has not yet contacted the object 3, the color block and the viewing window are dislocated, as shown in FIG. 4; when the housing 10 continues to rotate, the When the rotating member 20 compresses the elastic member 40 and abuts against the object 3 , the annular surface 22 pushes against the socket portion 34 to move the linking member 32 toward a side away from the viewing window, and then the pin member 335 drives the swinging member 33 to swing, and the color block is exposed to the outside corresponding to the visible window, as shown in FIG. In other embodiments, the at least one indicator portion may also be in other forms such as numbers, scales, plural color blocks, patterns, and the like.

The knob 1 further includes a locking mechanism 50. The locking mechanism 50 includes a lock 51 disposed on the housing 10 and a restricting member 52 rotatably connected to the rotating member 20. The lock 51 can be driven by a key. Move relative to the restricting piece 52 between a locking position and an unlocking position; when the locking piece 51 is in the locking position, the locking piece 51 and the restricting piece 52 do not interfere in a rotation direction of the restricting piece 52 , the The housing 10 cannot drive the rotating member 20 to rotate; when the lock 51 is in the unlocked position, the lock 51 and the restricting member 52 abut in the rotation direction, and the housing 10 can drive the rotating member 20 to rotate, thereby The knob 1 has the anti-theft function.

The housing 10 further includes a set of holes 13 , and the restricting member 52 is rotatably disposed in the set of holes 13 and sleeved on the rotating member 20 . In detail, the outer peripheral wall of the restricting member 52 has an annular groove radially inwardly recessed 521, the housing 10 further includes a latching member 14 radially protruding from the sleeve hole 13, the latching member 14 is partially embedded in the annular groove 521, and the latching member 14 is, for example but not limited to, a latch, Steel balls, C buckles, O-rings, etc., can all block the restricting member 52 in the axial direction A. As shown in FIG. The restricting member 52 includes an inserting portion 522 extending along the axial direction A, the inserting portion 522 includes at least a first abutting surface 523 extending parallel to the axial direction A, and the rotating member 20 is inserted into the inserting The portion 522 also includes at least one second abutting surface 23 abutting against the at least one first abutting surface 523 , so that the restricting member 52 can rotate synchronously with the rotating member 20 , and the structure is simple and easy to process and assemble. The restricting member 52 includes a first locking portion 524 , and the lock 51 includes a second locking portion 511 and a dodging portion 512 . In this embodiment, the first latching portion 524 includes a plurality of arcuate concave surfaces 524a disposed around the outer peripheral wall of the restricting member 52, and the second latching portion 511 includes an arcuate convex surface 511a corresponding to one of the arcuate concave surfaces 524a. The dodging portion 512 includes a flat section 512a; when the lock 51 is in the locking position, the dodging portion 512 faces the first latching portion 524, and the lock 51 does not interfere with the rotating member 20; when the lock 51 is in the unlocking position , the first latching portion 524 is engaged with the second latching portion 511 , as shown in FIG. 6 , the housing 10 and the rotating member 20 can be stably linked.
