Description

A kind of catapult support

Technical field

The utility model relates to a kind of catapult technology, particularly a kind of catapult support.

Background technology

At present, along with social development, electronic age arrives, and most people is associated with electronic product all day, have ignored outdoor activities to the able-bodied importance of people; But also there is increasing people to start to participate in outdoor activities in order to physical and mental health; Wherein, catapult has become the selection of many people.

Known, traditional catapult is fixing trident shape, and being not easy to very is carried and received.

Summary of the invention

Problem to be solved in the utility model is, provides a kind of catapult support, and structure is simple, be easy to carry and receive.

In order to realize the object solved the problems of the technologies described above, the utility model have employed following technical scheme:

A kind of catapult support, is characterized in that: comprise bow body, bow arm, lock-screw; The described bow body left and right sides is symmetrically arranged with the ladder chute for installing bow arm along the vertical direction, and the bottom land at the upper and lower two ends of ladder chute is provided with the screw coordinated with lock-screw; Described bow arm bottom is provided with and the sliding part bending body ladder chute and match, and the sliding part of bow arm is separately positioned in the ladder chute of the bow body left and right sides, and bow arm upper end is also provided with rubber band installation portion, and bow arm bottom is provided with through screwed hole; Described lock-screw is through the outside being arranged on bow arm after screwed hole, and the flighted length of lock-screw is greater than the degree of depth of screwed hole, bow arm is fixed on the bow body left and right sides, forms catapult support overall.

Concrete, the ladder chute upper port place of described bow body both sides is provided with upper limit position block; Like this, when bend arm along ladder chute upwards time upper limit position block can prevent bow arm slippage from going out ladder chute, be convenient to bend the fixing of arm.

Concrete, the ladder chute lower port place of described bow body both sides is provided with lower position block or lower limit pin for preventing from bending arm slippage.

Concrete, the screw of described bow body upper end ladder chute bottom land at least arranges one; Bow arm can be fixed on different positions like this, meet different needs.

Concrete, the rubber band installation portion of described bow arm upper end is for installing the elastic emission part of catapult.

moreconcrete, described bow body, bow arm, lock-screw are metal material.

moreconcrete, described ladder chute is the wide structure in the little inside of opening, and the sliding part of bow arm is the narrow structure of bottom wide upper portion.

moreconcrete, described rubber band installation portion is the bow arm upper end that there is the through hole of pass through openings side.

Concrete, described bow body is structure wide at the top and narrow at the bottom or upper and lower wide structure.

A kind of catapult support of this patent, in use, unclamped by the lock-screw outside bow arm respectively, the ladder chute along the external side of bow will bend arm upward sliding to operating position; Lock-screw is corresponding with the screw of ladder chute bottom land; Bow arm is fixed by lock-screw outside recycling bow arm respectively, completes the Job readiness of catapult support;

After a procedure, unclamp the lock-screw outside bow arm, bow arm is slided under ladder chute and collects position, tighten lock-screw, complete catapult support and close up.

By adopting technique scheme, the utility model has following beneficial effect: structure is simple, installs easy and simple to handle, saves space, is easy to carry and receives.

Detailed description of the invention

Below in conjunction with accompanying drawing, further explanation is explained to the utility model.But protection domain of the present utility model is not limited to concrete embodiment.

A kind of catapult support of the present utility model, comprises bow body 1, bow arm 2, lock-screw 3; Bow body 1 left and right sides is symmetrically arranged with the ladder chute for installing bow arm 2 along the vertical direction, the bottom land at the upper and lower two ends of ladder chute is provided with the screw coordinated with lock-screw, bow body 1 upper end ladder chute bottom land is provided with two screws, bow arm 2 can be fixed on different positions like this, meet different needs; Bow arm 2 bottom is provided with and the sliding part bending body 1 ladder chute and match, and the sliding part of bow arm 2 is separately positioned in the ladder chute of bow body 1 left and right sides, and bow arm 2 upper end is also provided with rubber band installation portion 6, for installing the elastic emission part of catapult; Bow arm 2 bottom is provided with through screwed hole, and lock-screw 3, through the outside being arranged on bow arm 2 after screwed hole, matches with the screw of ladder chute bottom land, bow arm 2 is fixed on bow body 1 left and right sides, forms catapult support overall.

The ladder chute upper port place of bow body 1 both sides is provided with upper limit position block 4, when bend arm 2 along ladder chute upwards time upper limit position block 4 can prevent bow arm 2 slippage from going out ladder chute, be convenient to bend the fixing of arm 2; The ladder chute lower port place of bow body 1 both sides is provided with the lower limit pin 5 for preventing from bending arm 2 slippage.

In use, respectively the lock-screw 3 outside bow arm 2 is unclamped, arm 2 upward sliding will be bent to operating position along the ladder chute outside bow body 1; Lock-screw 3 is corresponding with the screw of ladder chute bottom land; Bow arm 2 is fixed by lock-screw 3 outside recycling bow arm 2 respectively, completes the Job readiness of catapult support;

After a procedure, unclamp the lock-screw 3 outside bow arm 2, bow arm 2 is slided under ladder chute and collects position, tighten lock-screw 3, complete catapult support and close up.
