Abstract

The utility model discloses a spring type shock absorbing handle, which comprises a handle and a front cover. The handle is connected with the front cover via injection-molded soft plastic, a spring is arranged in the soft plastic, and two ends of the spring are respectively connected with the handle and the front cover. Besides, the two ends of the spring include a big end d and a small end s, the big end d of the spring is clamped at the mouth of the handle, the small end s of the spring is fixed at the bottom of a bolt via a nut, and the bolt is connected with a tool. The spring type shock absorbing handle is capable of reducing shock and avoiding failure due to accidental breaking.

Description

The spring damping handle

Technical field

The utility model relates to a kind of auxiliary damping handle, relates in particular to a kind of spring damping handle.

Background technology

The assist handle of existing electric tool is made up of handle, bolt, and its shortcoming is: the function of no vibration damping.For hand-held tool, especially on the hand held electric tool, vibration causes operator's use fatigue easily, therefore, be necessary to improve handle design, reduce vibration, alleviate operator's use fatigue, the minimizing instrument is delivered to the vibration of arm, improves the comfort of instrument, and will have the function that the accident of preventing pulls inefficacy.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of spring damping handle, can effectively reduce vibration, and prevents that the handle accident from pulling inefficacy.

The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of spring damping handle, comprise handle and protecgulum, wherein, flexible glue by injection moulding between described handle and protecgulum links to each other, be provided with spring in the described flexible glue, the two ends of described spring link to each other with handle, protecgulum respectively.

Above-mentioned spring damping handle, wherein, the two ends of described spring are respectively big end d and small end s, and the big end d of described spring is stuck in the handle oral area, and the small end s of described spring is fixed on the bottom of bolt by nut, and described bolt links to each other with instrument.

The utility model contrast prior art has following beneficial effect: the spring damping handle that the utility model provides, by flexible glue and spring are set, can effectively reduce vibration, and prevent that the handle accident from pulling inefficacy between handle and protecgulum.

Description of drawings

Fig. 1 is the utility model vibration dampening handle operation principle schematic diagram;

Fig. 2 is the utility model spring damping handle structural representation.

Among the figure:

1 handle, 2 springs, 3 nuts

4 flexible glues, 5 protecgulums, 6 bolts

7 instruments

The specific embodiment

The utility model will be further described below in conjunction with drawings and Examples.

Fig. 1 is the utility model vibration dampening handle operation principle schematic diagram; Fig. 2 is the utility model spring damping handle structural representation.

See also Fig. 1 and Fig. 2, the spring damping handle that the utility model provides comprises handle 1 and protecgulum 5, and wherein, 5 flexible glues 4 by injection moulding of described handle 1 and protecgulum link to each other, described flexible glue is provided with spring 2 for 4 li, and the two ends of described spring 2 link to each other with handle 1, protecgulum 5 respectively.

The handle that the utility model provides can effectively reduce vibration, and prevents that the handle accident from pulling inefficacy, specifically describes as follows:

1. vibration-damping function:

Add flexible glue in the handle arrangement that the utility model provides and increase cushioning effect.5 flexible glues 4 by injection moulding of handle 1 and protecgulum that operator's hand grips are connected with

spring

2,6 on handle 1 and bolt have flexible glue 4 to separate, play and reduce owing to the vibration e that produces in instrument 7 courses of work is directly delivered to operator's function on hand, the vibration f that the operator is experienced reduces.

2. anti-slip function:

Handle is stressed when excessive, comprise pulling force a, bending force b, torsion c, flexible glue 4 begins to extend torsional deflection, handle 1 begins to become big with the distance of protecgulum 5, by spring 2 bolt 6 and handle 1 are effectively coupled together, prevented that flexible glue 4 from excessively being stretched and cause elasticity connect to lose efficacy (breaking away from or cracking etc. as colloid).

In order further to improve the anti-slip function, spring 2 can select for use one to be big end d, and the other end is the type of small end s, and the big end d of spring is stuck in handle 1 oral area, and small end s is fixed on the bottom of bolt 6 by nut 3.Spring can vibration damping, has also born most pulling force or impulsive force that comes from the outside, and has effectively reduced the stressed of flexible glue 4, plays the effect of avoiding flexible glue 4 excessively to extend and losing efficacy, and has guaranteed that the handle 1 that operator's hand grips is connected reliably with 7 of instruments.

Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.

Claims

1. spring damping handle, comprise handle (1) and protecgulum (5), it is characterized in that, flexible glue (4) by injection moulding between described handle (1) and protecgulum (5) links to each other, described flexible glue (4) lining is provided with spring (2), and the two ends of described spring (2) link to each other with handle (1), protecgulum (5) respectively.

2. spring damping handle as claimed in claim 1, it is characterized in that, the two ends of described spring (2) are respectively big end d and small end s, the big end d of described spring (2) is stuck in handle (1) oral area, the small end s of described spring (2) is fixed on the bottom of bolt (6) by nut (3), and described bolt (6) links to each other with instrument (7).
