Description

The safe cut-off switch of sports equipment

Technical field

The utility model relates to a kind of safe cut-off switch of sports equipment, specifically, is meant a kind of main conduction to be placed within the device with member, thereby prevents that it is impaired or damage, with the effective prolongation safe cut-off switch in its useful life.

Background technology

As everyone knows; usually with power-actuated various sports equipments, can add an emergency safety cut-off switch in the appropriate location of power path mostly, so that when danger takes place; can with the simplest and easy and the most rapidly mode with dump, and then the protection user and around personnel's safety.

At present, in special-purpose safety switch, the most widely used is a kind of so-called safety outage pin, and its use principle is to utilize the insertion of a tip body to form conducting state and extract the formation off state out, to reach the security purpose of expection.

With regard to common traditional design, the tip body that uses is the insulator of being made by plastic material, conventional safety outage pin is the insertion that utilizes this insulation tip body, makes each power supply contact join realizing conducting, and makes each power supply contact escape and realize opening circuit after extraction; But this structure Design is the inside that all power supply contacts all is arranged on housing, therefore, if in case the significant points of this insulation tip body ruptures, then fracture location will be stayed enclosure interior forever, even cause the user to extract this insulation tip body out, but still can't bring into play the cut-out function of its expection, thereby the safety that seriously jeopardizes the user.

Therefore, aforesaid traditional type tip body taken place for above-mentioned reasons several can't normal power down fault, and injure user's serious accident, so there is the practitioner that it is improved, its evolutionary approach is that intermediary's electric conductor and tip body are combined as a whole, thereby makes after tip body is drawn out of, because intermediary's electric conductor also can be drawn out of together, cause two power supply contacts of enclosure interior to contact, thereby can more safely use.

But; actual operating position shows; electric conductor is detached out housing together with tip body owing to wherein be situated between; therefore regular meeting causes the wearing and tearing and the distortion of intermediary's electric conductor because user's preservation is improper; and then have a strong impact on its power turn-on effect and power supply stability, therefore also need further to be improved.

The utility model content

The inventor is in view of existing conventional like product imperfect part in design, then rely on it skillfully to be engaged in the practical experience of the industry for many years, the exploitation of actively concentrating on studies, thus the utility model is come out.

Therefore, the topmost purpose of the utility model is, with with the constant enclosure interior that is arranged on of intermediary's electric conductor as basic design main shaft, and suitable interlock and block resistance between the cooperation associated components, thereby provide a kind of safe cut-off switch, avoiding the possible damage situations of intermediary's electric conductor, and can guarantee the following normal performance of the effect of opening circuit expected.

The safe cut-off switch that the utility model provides is two power connections are cooperated elastic component and firmly to be contained in the housing, and keep a suitable spacing, and be provided with a hollow spacing zone with respect to the ccontaining position of tip body and sliding sleeve at housing, thereby the ccontaining one conducting sliding sleeve that driven by tip body, and make this sliding sleeve only can in spacing zone, slide and can't deviate from housing.

Use safe cut-off switch provided by the invention, when inserting in the spacing zone of housing and drive sliding sleeve, moves tip body to the power connection direction, after making sliding sleeve touch two power connections, can form the conducting state of circuit, and when tip body to motion in the other direction and when driving sliding sleeve and withdrawing from the contacting of power connection, just can reach the purpose of the safety outage of expection.

Embodiment

Below in conjunction with specific embodiment, the utility model is described in further detail.Should be understood that following examples only are used to the utility model is described but not are used to limit scope of the present utility model.

Embodiment 1, safe cut-off switch

For being illustrated more clearly in design of the present utility model, the inventor specially removes the enclosing cover (figure does not show) of housing 10, so that can know the basic configuration of understanding its inner each associated components.

Consult Fig. 1-4 (for the diagram of a preferred embodiment of the present utility model), by Fig. 1-4 as can be known, the safe cut-off switch that the utility model provides comprises:

One housing 10 firmly disposes two power connections 11, and two elastic components 12 that are held in these two power connections, 11 outsides usually, and makes 11 of above-mentioned power connections keep a suitable spacing; Relative inner edge surface at two power connections 11 is provided with conduction contact block 13 again; Simultaneously, this two power connection 11 also has to be emerging in and exposes end 14 beyond the housing 10, to be used to link power path, at the ccontaining position with respect to tip body 30 and sliding sleeve 20, also is provided with the spacing zone 15 of a hollow form;

One sliding sleeve 20 is made by conducting metal, is contained in the spacing zone 15 of housing 10, is bonding state slidably, but can't deviates from housing 10;

One tip body 30 is an insulator, can be inserted in the spacing zone 15 of housing 10 by the outside, so that become the circuit turn-on state, or is drawn out of and becomes off state.

Therefore, assembling by above-mentioned member, insert the spacing zone 15 of housing 10 when tip body 30, driving sliding sleeve 20 moves to power connection 11 directions, and after making sliding sleeve 20 touch two contact blocks 13, just can form the conducting state of circuit, and when tip body 30 to motion in the other direction and when driving sliding sleeve 20 and withdrawing from (shown in Fig. 5,6), just can reach the safety trip purpose of expection with the contacting of contact block 13.

Shown in Fig. 7,8, why tip body 30 can drive the displacement of sliding sleeve 20, mainly is to utilize its ring short slot 31 set in corresponding end to be engaged in the set indent holding section 21 of sliding sleeve 20 inner correspondence positions, makes both can engage interlock mutually; And why the spacing zone 15 of housing 10 can be retained in sliding sleeve 20 its inside, then is to utilize in the set anti-hook portion 16 of the nearly open end of this spacing zone 15 inner edge, so that this sliding sleeve 20 when being moved to this anti-hook portion 16, can be forced to and tip body 30 breaks away from.

Therefore, by above rigorous design, the utility model can be eliminated the various serious drawback of conventional products in design and use, thereby has safe guarantee and longer useful life.
