Abstract

The utility model relates to a gripper, which comprises a tongs body, a holding part and a lower fastener, wherein the tongs body is provided with a protruding part; the holding part is movably arranged on the tongs body; and the lower fastener is provided with a containing space, and the lower fastener is arranged at the lower end of the tongs body. The upper end of the tongs body is fixedly provided with a pin, and the pin is movably connected with the holding part. The tongs body with the protruding part is arranged in the gripper, so the ligature between the holding part of the gripper and the center of gravity of the gripper and the ligature between the gripped point of the gripped body and the center of gravity of the gripped body can not form a straight line when the gripper is used for gripping. After the gripped body is gripped, a downward force is exerted on the gripped body due to the effect of the gravity, the force enables the two lines have a requirement of tending to coincide, but the structural design of the protruding part of the gripper makes the trend incapable of being realized, so the gripped body is firmly clamped in the gripper, and the purpose of gripping a clean water barrel by the gripper is realized.

Description

A kind of gripping apparatus

Technical field

The utility model relates to the lifting instrument of physical construction, relates in particular to a kind of gripping apparatus.

Background technology

Along with improving constantly of people's living standard and health environment-friendly consciousness, domestic water and potable water are strict to be distinguished.Quote water to supply at a fixed location, be carried in the family by bottled water and drink on the water dispenser.Present 5 gallons of water-purifying tanks of general-duty have on the market extensively been adopted and have obtained client's approval by water dispenser producer.

But the water-purifying tank that fills with water purification weighs 20 kilograms for every barrel, and the bucket wall of water-purifying tank does not have suitable grasping part, and the water-purifying tank that fills with water purification is transported to and needs carrying in the family, thereby has brought very big inconvenience to daily life.Simultaneously, existing carrying does not have instrument and can use, and mainly with portable water-purifying tank neck, both hands are clasped, and the back of the body is chosen several modes pickaback.Significantly, above-mentioned method for carrying safety factor is low excessively, and handling efficiency is low.A kind of not only convenient but efficiently the water-purifying tank gripping apparatus become active demand at home undoubtedly.

The problem that prior art exists, this case designer relies on the industry experience for many years of being engaged in, and the active research improvement is so there has been a kind of gripping apparatus of the utility model.

The utility model content

The utility model is in the prior art, and the mode safety factor of traditional carrying water-purifying tank is low, and the low inferior defective of handling efficiency, and a kind of gripping apparatus is provided.

In order to address the above problem, the utility model provides a kind of gripping apparatus, and described gripping apparatus comprises: comprising: the handgrip body, and described handgrip body has protrusion; Grip part, described grip part are movably arranged on the described handgrip body; Following fastener has by first storage tank and second storage tank and encloses the accommodation space that forms, and described fastener down is arranged on described handgrip body lower end.Described handgrip body upper end fixedly installs pin, and described pin flexibly connects with the grip part that is set in the described pin outside.

Optionally, described down fastener and described handgrip body adopt integrated mode to prepare.

Optionally, described pin is fixed as one described handgrip body and described fastener down.

Optionally, described handgrip body adopts ferrous material or the preparation of aluminum alloy.

Optionally, described accommodation space is according to waiting to grasp mechanical planform design.

The utility model is by being provided with the handgrip body with protrusion in gripping apparatus, make that when using gripping apparatus and grasp work the line of the grip part of described gripping apparatus and gripping apparatus center of gravity and quilt are grabbed body can't be become straight line by the place of grabbing and the line of being grabbed between the thing center of gravity.When being grabbed after thing picked up, because action of gravity is grabbed thing a downward power is arranged, this power makes foregoing two lines that a requirement that is tending towards overlapping be arranged, and because gripping apparatus design-calculated structure can't realize this trend, so just make and grabbed thing and be stuck in firmly in the gripping apparatus, realized that the utilization gripping apparatus catches the purpose of water-purifying tank.And then it is convenient to make that water-purifying tank grasps, and handling efficiency improves.
