Description
- 1. Field of the invention
- The present invention relates to a connecting rod structure of a laser sight of a gun, more particularly one, which includes an expanding and fixing sleeve to be capable of coupling a laser sight to any one of various guns with different-diametered joining holes.
- 2. Brief Description of the Prior Art
- Various survival games are exciting, entertaining and getting popular. Players are divided into groups, and compete against each other with BB guns or paint pellet guns in a kind of survival game. In order to be more accurate at shooting with BB guns or paint pellet guns in such a survival game, the players can use the original front sight of their gun or a laser sight, which is usually coupled to the gun in a separable manner by means of a connecting rod.
- A currently existing connecting rod structure of a laser sight of a gun has a threaded portion at a front end, and a truncated-cone shaped insertion portion at a rear end; the laser sight is threadedly joined on the front threaded portion of the connecting rod at a threaded hole thereof while the connecting rod is joined to the gun by means of inserting the truncated-cone shaped insertion portion of the connecting rod in a joining hole of the gun. The above-mentioned connecting rod structure is found to have the following drawbacks:
- 1. The diameter of the truncated-cone shaped insertion portion of the connecting rod can be changed. Therefore, the connecting rod can only be used to couple the laser sight to those guns that have a joining hole matching the truncated-cone shaped insertion portion thereof; in other words, the connecting rod isn't convenient to use.
- 2. The connecting rod and the joining hole of the gun can wear after the connecting rod have been joined to and taken down from the gun many times. Consequently, the connecting rod can no longer be fixedly joined to the joining hole of the gun, and the laser sight can move relative to the gun in use.
- Therefore, it is a main object of the present invention to provide an improvement on a connecting rod structure of a laser sight of a gun to overcome the above problems.
- A connecting rod in accordance with an embodiment of the present invention includes a rod body, and an expanding and fixing sleeve with a truncated-cone shape. The rod body is passed through the sleeve while the sleeve is inserted in a joining hole of the gun. The rod body has a front threaded portion joined to the laser sight, a middle truncated-cone shaped section, and a male threaded portion adjoining the truncated-cone shaped section. The expanding and fixing sleeve has a lengthways extending gap thereon, and a truncated-cone shaped hole receiving the truncated-cone shaped section of the rod body; the taper of the truncated-cone shaped section of the rod body matches that of the truncated-cone shaped hole of the sleeve. The sleeve has a female threaded portion in the truncated-cone shaped hole, which is threadedly engaged with the male threaded portion of the rod body. Therefore, the sleeve can be expanded to closely come into contact with the joining hole of the gun by means of turning the rod body. In other words, the connecting rod can be used to couple the laser sight to any one of various guns with different-diametered joining holes.
- The present invention will be better understood by referring to the accompanying drawings, wherein:
-
FIG. 1 is an exploded perspective view of the present invention, -
FIG. 2 is a perspective view of the present invention, -
FIG. 3 is a partial sectional view of the present invention in use (1), -
FIG. 4 is a partial sectional view of the present invention in use (2), and -
FIG. 5 is a side view of a gun with the connecting rod of a laser sight according to the present invention. - Referring to
FIGS. 1 and 2 , a preferred embodiment of a connecting rod (a) of a laser sight in the present invention consists of arod body 1, an expanding and fixingsleeve 2, and astopping ring 3. - Referring to
FIG. 5 as well, therod body 1 includes a threadedportion 10 at a front end thereof, which is to be connected to a laser sight (b) of a gun; the laser sight (b) has a threaded hole (b1), and the threadedportion 10 of therod body 1 is threadedly inserted in the threaded hole (b1). Therod body 1 includes a contactingblock 11 next to the threadedportion 10 so that the laser sight (b) will be pressed against the contactingblock 11 after therod body 1 is joined to the laser sight (b). - Furthermore, the
rod body 1 has a truncated-coneshaped section 12 next to a rear end thereof while the expanding and fixingsleeve 2 has a truncated-cone shape, and a truncated-cone shaped throughhole 21 to receive the truncated-coneshaped section 12 of therod body 1, as shown inFIG. 3 ; the taper of the truncated-coneshaped section 12 of therod body 1 matches the taper of the truncated-cone shaped throughhole 21 of thesleeve 2. - The expanding and fixing
sleeve 2 has alengthways extending gap 22 thereon, and a female threadedportion 211 in a smaller portion of the truncated-cone shaped throughhole 21 thereof. Furthermore, therod body 1 has a male threadedportion 13 adjoining a rear end of the truncated-coneshaped section 12, and anannular groove 14 on a rearmost portion thereof. - Therefore, when the male threaded
portion 13 of therod body 1 is threadedly passed through the female threadedportion 211 of the truncated-cone shaped throughhole 21 of the expanding and fixingsleeve 2, the truncated-coneshaped section 12 of therod body 1 will be passed into the truncated-cone shaped throughhole 21 of the expanding and fixingsleeve 2. Consequently, the expanding and fixingsleeve 2 will be forced to expand; the diameter of the expanding and fixingsleeve 2 will increase with the distance the truncated-coneshaped section 12 of therod body 1 is passed into the truncated-cone shaped throughhole 21 of the sleeve. - The stopping
ring 3 is C-shaped. In Assembly, therod body 1 is passed through the truncated-cone shaped throughhole 21 of the expanding and fixingsleeve 2, with the male threadedportion 13 thereof being threadedly engaged with the female threadedportion 211 of the expanding and fixingsleeve 2, and with theannular groove 14 being outside the smaller end of thesleeve 2, and thestopping ring 3 is positioned around theannular groove 14 so as to prevent the expanding and fixingsleeve 2 from separating from therod body 1. - In use, referring to
FIGS. 3 and 5 , the connecting rod (a) is inserted in a joining hole (c1) of a gun (c) from the smaller end of the expanding and fixingsleeve 2. Next, therod body 1 is turned so that the male threadedportion 13 thereof moves further into the female threadedportion 211 of the expanding and fixingsleeve 2, and the truncated-coneshaped portion 12 thereof moves inwardly of the truncated-cone shaped throughhole 21 of the expanding and fixingsleeve 2. Therefore, the expanding and fixingsleeve 2 increases its diameter so as to closely come into contact with the inner side of the joining hole (c1) of the gun (c). Next, the threadedportion 10 of therod body 1 of the connecting rod (a) is threadedly inserted in the threaded hole (b1) of the laser sight (b); thus, the laser sight (b) is securely joined on the connecting rod (a). Consequently, the laser sight (b) is firmly coupled to the gun (c) by means of the connecting rod (a). - The diameter of the expanding and fixing
sleeve 2 will decrease if therod body 1 is turned in such a direction that the truncated-cone shapedportion 12 thereof moves outwardly of the expanding and fixingsleeve 2; thus, the connecting rod (a) can be separated from the joining hole (cl) of the gun (c). Therefore, the connecting rod (a) of the present invention can be used to couple the laser sight (b) to any one of various guns with different-diametered joining holes. The joining hole (c1) of the gun (c) and the expanding and fixingsleeve 2 can wear, and the connecting rod (a) can become loose after having been used for a long time. To handle this problem, the user only has to turn therod body 1 so as to further increase the diameter of the expanding and fixingsleeve 2; after the diameter of the expanding and fixingsleeve 2 in increased, the connecting rod (a) can be firmly fixed in the joining hole (c1) of the gun (c) again. - From the above description, it can be seen that the present invention has the following advantages:
- 1. The expanding and fixing sleeve of the connecting rod of the present invention will increase its diameter so as to closely come into contact with a joining hole of a gun when the rod body is turned so that the male threaded portion thereof moves further into the female threaded portion of the expanding and fixing sleeve, and the truncated-cone shaped portion thereof moves inwardly of the truncated-cone shaped hole of the expanding and fixing sleeve. Therefore, the connecting rod of the present invention can be used to couple a laser sight to any one of various guns with different-diametered joining holes.
- 2. The joining hole of the gun and the expanding and fixing sleeve can wear to cause the connecting rod of the present invention to become loose after having been used for a long time; to handle this problem, the user only has to turn the rod body of the connecting rod so as to further increase the diameter of the expanding and fixing sleeve; thus, the connecting rod will be firmly joined on the gun again.
