Abstract
The utility model discloses a novel caster anchor hook device which comprises spiral hooks, a launcher end connector and a rope hook, wherein the upper part of the launcher end connector forms circular arc camber, and the lower end is provided with a cylindrical hole and the rope hook; and the spiral hooks are fixed on the circular arc camber of the launcher end connector, three spiral hooks are uniformly distributed on the circular arc camber and form a spiral shape, and the spiral lead angle is greater than the equivalent friction angle between the anchor hook and the air. The utility model solves the problems of great resistance and short launching distance of the traditional anchor hook during the launching process, the shape of the hooks on the anchor hook is improved in design, the straight type is changed into the spiral type, the resistance of the anchor hook in the air can be reduced, and the launching distance is increased.
Description
Technical field
The utility model relates to the saving casting device technical field, specifically belongs to a kind of novel saving casting device grasp device.
Background technology
Existing grasp device all is an in-line arrangement; But simple in structurely do not consider that grasp seldom considers the factors such as resistance of air in the process of dishing out; Cause the emission process resistance to increase, make transmitting range can not reach due scope, if want transmitting range far away; Must strengthen the power of emission so, cause use cost increase etc. unfavorable.
The utility model content
The purpose of the utility model provides a kind of novel saving casting device grasp device; Solve the existing problem that grasp resistance in emission process is big, transmitting range is near; Design improves the shape of the crotch on the grasp; Become in-line arrangement spiral, can reduce the aerial resistance of grasp, increase transmitting range.
The technical scheme that the utility model adopts is following:
A kind of novel saving casting device grasp device; Comprise spiral crotch, transmitter end interface and rope hook, interface top, described transmitter end becomes circular arc camber, and the lower end has a cylindrical hole and rope hook; The spiral crotch is fixed on the interface circular arc camber of transmitter end; Described spiral crotch has three crotches to be uniformly distributed on the circular arc camber, and linear in the shape of a spiral formula, and its lead angle is greater than the equivalent friction angle between grasp and the air.
Said spiral crotch and rope hook all are welded to connect with transmitter end interface.
Described three crotch sizes are identical.
Compared with present technology, the beneficial effect of the utility model is following:
The utility model adopts spiral crotch, have simple and compact for structure, be easy to processing; And crotch realizes that through welding procedure it is connected with the impulse flask end interface, and Design and Machining is convenient, can reduce the processing and manufacturing cost of grasp, improves the market competitiveness.Crotch is carried out spiral mentality of designing, can make the resistance force diminishes of grasp in emission process, makes transmitting range become big, reduces the power source that provides in the emission process, reduces use cost, increases economic efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the sketch map of the utility model helix arrangement.
The specific embodiment
Referring to accompanying drawing, a kind of novel saving casting device grasp device comprises spiral crotch 1, transmitter end interface 2 and rope hook 3; Interface 2 tops, transmitter end become circular arc camber; The lower end has a cylindrical hole 4 and rope hook 3, and spiral crotch 1 is fixed on the interface circular arc camber of transmitter end, and spiral crotch 1 has three identical crotches of size to be uniformly distributed on the circular arc camber; And linear in the shape of a spiral formula, its lead angle is greater than the equivalent friction angle between grasp and the air.Spiral crotch 1 all is welded to connect with transmitter end interface 2 with rope hook 3.The saving casting device grasp was put into the transmitter top cylindrical hole 4 of saving casting device grasp earlier before not working, and linked up with lanyard on 3 in rope.When saving casting device in when emission, transmitter and grasp band rope and are launched together, grasp is when hitting the mark and hook target, transmitter separates with grasp.Grasp utilizes the helix principle to reduce air drag in emission, realizes emission at a distance.
