Abstract

The utility model discloses a clamp force continuous adjustable pinchcock, which comprises a grip, a left clamping body, a right clamping body, a torsion spring, a rack and a swing gear. The grip is sleeved respectively at the end of the right clamping body and the left clamping body; a part is removed respectively from the central part of the right clamping body and the left clamping body to form a groove; the left clamping body, the right clamping body and the torsion spring are connected as a whole by a bolt; the rack and the swing gear are arranged on the left clamping body and the right clamping body; when the clamping body is rotated, the rack and the swing gear can be driven to move relatively for adjustment of the clamping force and self-locking.

Description

The continuous adjustable spring folder of clamping force

The utility model relates to a kind of five metals anchor clamps of clamping object.

Spring clip is a kind of instrument that is used for the clamping object commonly used.Existing spring clip generally adopts nylon or plastics to make, and its structure mainly is made up of clamp and spring two large divisions, and clamping force is provided by used spring force, and clamping force can not be regulated.Like this, under the occasion of the different clamping force of needs, just can't use, perhaps can only just can carry out clamping, so just bring inconvenience to the user by means of other auxiliary.

In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of clamping force spring perch adjustable continuously, that also can use in multiple occasion.

The purpose of this utility model is achieved like this:

The utility model has designed two can load onto tooth bar and pendulum tooth separately, the clamp that is installed together mutually, clamp can rotate mutually, and drives tooth bar and put adjusting and the realization self-locking that tooth moves mutually and carries out clamping force, thereby reaches the purpose that keeps corresponding clamping force clamping object.And, then can unclamp self-locking by stirring the pendulum tooth, open clip, and take out the object in the clip.

Through the utility model after the above-mentioned design, compare with existing spring clip, have the following advantages:

1, be skillfully constructed, rational in infrastructure;

2, multiple functional, because clamping force is not directly to be provided by spring, just the thrust by hand provides, so can be used for the object that the different clamping forces of all kinds of need are carried out clamping.

Specific embodiments of the present utility model is as shown in drawings:

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the structural representation of right clamping body of the present utility model

Fig. 3 is the side view of right clamping body of the present utility model

Fig. 4 is the structural representation of left clamp of the present utility model

Fig. 5 is the side view of left clamp of the present utility model

Fig. 6 is the structural representation of tooth bar of the present utility model

Fig. 7 is the structural representation of pendulum tooth of the present utility model

Below in conjunction with accompanying drawing, specific embodiments of the present utility model is further specified:

The continuous adjustable spring folder of clamping force comprises chuck 1, left clamp 2, right clamping body 3, torsion spring 4, tooth bar 5,7 six parts of pendulum tooth.Chuck 1 is set in the end on the left and

right clamp

2,3, respectively removes a part in the centre of left and right clamp, forms a groove 11, and left clamp 2, right clamping body 3 and torsion spring 4 are connected in one by bolt 10; Torsion spring 4 can make the chuck 1 on the left and right clamp be in normally open.Belly at left and right sides clamp handle part is equipped with groove, and tooth bar 5 is installed in the groove of left clamp 2, and pendulum tooth 7 is installed in the groove of right clamping body 3 by bearing pin 8; The tooth bar 5 that is arranged in the left clamp groove is arc-shaped structure, is provided with above and puts the pawl that tooth 7 profiles of tooth are meshed; On pendulum tooth 7, be provided with torsion spring 9, be in normal engagement to guarantee pendulum tooth 7 with tooth bar 5.Ridge at pendulum tooth 7 is provided with wrench boss 12, pulls boss 12 with finger, and pendulum tooth 7 and tooth bar 5 are broken away from, and opens clip and takes out caught object.Because a part is respectively removed in the centre of left and right sides clamp, and is combined into together by bolt, so clip in use can be because of the stressed deflection that causes.

Worker of the present utility model is achieved like this with mode:

Hold spring clip with the right hand, little firmly clamping is pulled the boss of putting on the tooth 7 12 with thumb, and pendulum tooth 7 and tooth bar 5 are broken away from, and unclamps the right hand, opens clip.Put gripped object into, or clip is moved on the gripping object, clamp clip with the right hand or left hand, clamping force can determine the size of the grip force of hand according to the size of required clamping force, with the needs of the different clamping forces that adapt to various gripped objects.Unclamp the hand of holding clip, pendulum tooth 7 with tooth bar 5 engagements, promptly reaches the purpose of self-locking under the effect of torsion spring 9.
