Description

The clamp structure-improved

Technical field

The utility model relates to a kind of clamp, particularly a kind of structure-improved of clamp fast easy and simple to handle.

Background technology

Existing clamp structure, disclose as M284485 number " clamp structure-improved " novel patent case of Taiwan patent announcement, comprise the moving caliper and the fixed caliper that are arranged in respectively on the guide rod, structure with moving caliper is an example, and this moving caliper utilizes the knob of in-line, does just successional/counter-rotating, can on guide rod, do the displacement adjustment, locks to reach/get loose in the use effect of guide rod, and the running key of this continous way is that this knob adopts common screw-rod structure.

Yet, utilize screw-rod structure to impose the mode of continous way rotation, no doubt can make moving caliper obtain the dismounting purpose of expection, but the flight pitch of common screw is little, must rotate many circles in the operation, screw rod just can obviously advance (or retreating), and therefore, not only service speed is slow, and whether moving caliper lock, fully with operator's feel, so, and can't guarantee the quality that locks, and careless slightly, just have influence on processing effect, even cause processing unexpected, indiscreet and negligent must not.

The utility model content

Main purpose of the present utility model is to provide the simple and easy clamp fast of a kind of operation structure-improved.

The clamp structure-improved that provides a kind of locking condition can guarantee locking effect is provided secondary objective of the present utility model.

In order to reach above-mentioned purpose, solution of the present utility model is:

The clamp structure-improved, comprise a fixed caliper and a moving caliper, this fixed caliper fastens on a guide rod, this moving caliper fastens on this guide rod, and with this fixed caliper distance in order to the clamping workpiece of being separated by, the workpiece of the size of this distance clamping different size with the displacement of moving caliper, moving caliper includes: an adjustable cramp main body, has a jaw piece in order to the clipping workpiece, one fastens the guide hole in guide rod, one multistart thread portion, one axle track that is positioned at these central authorities of multistart thread portion and is communicated with this guide hole, this axle track has an axle hole and two reamer that are provided with relatively; And: one adjusts assembly, has that the solid adjustment button, in this multistart thread portion of a spiral shell is placed through this axle track and in order to pushing against the snib of this guide rod one end, and a pin member that is through at the perforation of one of this snib.

Above-mentioned each reamer extends radially outwardly from the axle hole, and is formed with one first most end and one second most end respectively, and the pin member of this adjustment assembly is limited in this reamer; When the adjustment button was locked in this multistart thread portion, the two ends of this pin member were fastened on the respectively first most end of this reamer respectively; When the adjustment button got loose in this multistart thread portion, the two ends of this pin member were fastened on the respectively second most end of this reamer respectively.

After adopting said structure, it is solid in multistart thread portion that the utility model will be adjusted the button spiral shell, when needs lock/get loose adjustment, only need rotate multistart thread portion a little, can order about moving caliper and on guide rod, break away from or lock, operate simple and easy fast, and can guarantee to lock errorless.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

With reference to Fig. 1 and shown in Figure 2, be the structure improved specific embodiment of the utility model clamp, comprise a fixed caliper 100 and a moving caliper 200.

Fixed caliper 100 fastens on a guide rod 300, and this moving caliper 200 fastens on this guide rod 300, and is oppositely arranged with this fixed caliper 100, with clamping one workpiece (not shown).The one section suitable distance of being separated by between moving caliper 200 and the fixed caliper 100 is made as D, when moving caliper 200 during along guide rod 300 displacements, can change the size of distance D, with the workpiece of suitable clamping different size.

Moving caliper 200 comprises adjustable cramp main body 10 and adjustment assembly 20, as shown in Figure 1.

Adjustable cramp main body 10 has a jaw piece 11, in order to the clipping workpiece and fastens the axle track 14 that is positioned at these 13 central authorities of multistart thread portion and is communicated with guide hole 12 in guide hole 12, a multistart thread portion 13, of guide rod 300.This axle track 14 has reamer 142,143, two reamer 142,143 that an axle hole 141 and two relatively is provided with and is from the axle hole 141 extend radially outwardly, and is formed with first respectively and holds 1421,1431 and second to hold 1422,1432 to the greatest extent to the greatest extent.

Adjust assembly 20 and comprise the solid adjustment button 21 in multistart thread portion 13 of spiral shell, be placed through axle track 14 and in order to pushing against the snib 22 of guide rod 300 1 ends, and axle is through at the pin member 23 of the perforation 221 on this snib 22, this pin member 23 is limited in the reamer 142,143.

When the utility model uses, with reference to Fig. 3, be fastened on first of reamer 142,143 respectively at pin member 23 two ends of snib 22 when holding 1421,1431 to the greatest extent when axle is solid, adjust button 21 and be locked in multistart thread portion 13, this moment, moving caliper 200 was locking condition at an end of guide rod 300; To adjust button 21 along clockwise rotating, being fastened on second of reamer 142,143 respectively at pin member 23 two ends of snib 22 holds 1422,1432 to the greatest extent admittedly to make axle, and this moment, moving caliper 200 was the state of getting loose at an end of guide rod 300.

In sum, the utility model clamp structure-improved, multistart thread portion 13 by this moving caliper 200, make when needing to adjust moving caliper 200, rotate 1/4th circles as long as will adjust button 21, just can order about moving caliper 200 and on guide rod 300, break away from or lock, therefore quite simple and easy and convenient in the operation.And, lock and all do the restriction location of diverse location with the state that gets loose according to pin member 23, therefore, it is errorless more can to guarantee to lock, and not only can not increase the inconvenience of operation, more can guarantee the security of work.

The above person of thought, only be an embodiment of the present utility model, can not limit practical range of the present utility model with this, be that all claim and utility model simple equivalent that description is done according to the utility model application change and modify, all should belong in the scope that the utility model patent contains.
