Description

Technical Field

[0001] The invention relates to the technical field of night vision goggle installation, and in particular to a connecting mechanism for installing a four-tube night vision goggle host. Background Art

[0002] The existing connection mechanism installed on the night vision goggle host is mostly used for the installation and fixation of double-tube night vision goggles. It mainly includes a front and rear adjustment group and a left and right adjustment group. The night vision goggle host is installed by connecting the mirror body with the front and rear adjustment group and the left and right adjustment group. Although the existing night vision goggle host installation mechanism has the functions of pupil distance adjustment, front and rear adjustment, and tilt angle adjustment, its structural form is suitable for the installation of binocular night vision goggles, but not for the installation and disassembly of four-tube night vision goggles. The existing night vision goggle host installation mechanism is fixedly connected to the night vision goggle host and cannot be installed or disassembled at will. The angle of eccentric tilt adjustment is easily affected by external forces, and the eccentric adjustment mechanism is easy to loosen, and a certain tilt angle cannot be fixed at will. Among them, the pupil distance adjustment, front and rear adjustment, and tilt angle adjustment do not have fastening devices, which are easy to cause looseness. They need to be readjusted every time they are used. The adjustment components are used frequently, causing wear of various parts of the mechanism and increased matching clearance. Summary of the invention

[0004] To solve the above problems, one aspect of the present invention provides a connection mechanism for installing a four-tube night vision goggle host, which is used to connect the four-tube night vision goggle host, including: an eye distance adjustment component and a front-to-back adjustment component; the eye distance adjustment component includes: a housing, a pin holder connected to the four-tube night vision goggle host through a dovetail groove; an eccentric rod and a guide rod parallel to each other are installed on the housing; two grooves are opened on the cylindrical surface of the eccentric rod, and an eccentric hole is opened in its axial direction, the eccentric hole passes through the groove, and left and right adjustment screws are installed in the eccentric hole, the left and right adjustment screws leak out at the groove, the pin holder is movably connected with the left and right adjustment screws at the groove, and the guide rod passes through the pin holder; rotating the eccentric rod can make the pin holder rotate with the guide rod as the axis; left and right adjustment hand wheels are arranged at both ends of the left and right adjustment screws. The front-to-back adjustment component includes a front-to-back adjustment bracket installed on the upper end of the housing through a dovetail fit, and a front-to-back adjustment screw and a front-to-back adjustment hand wheel are installed between the housing and the front-to-back adjustment bracket, so that the housing can move forward and backward relative to the front-to-back adjustment housing. The night vision goggle host is provided with a dovetail groove, and the stud seat is provided with a dovetail matching therewith.

[0005] A further technical solution is that the front and rear adjustment bracket includes a cover body part connected to the shell, a clamping joint and a hollow connection part connecting the cover body part and the clamping joint, an electrode seat is arranged on the side of the hollow connection part, the electrode seat penetrates the hollow connection part, and a wire extending to the shell is connected from the inside of the hollow connection part; a contact pin connected to the wire is arranged on the contact pin seat, and a contact pin hole matching with the contact pin is arranged in the dovetail groove on the body of the night vision goggle host, and the positive and negative electrodes of the night vision goggle host are arranged in the contact pin hole. The clamping joint is a connection structure for installing the four-tube night vision goggle host connection mechanism on other components such as a helmet. When the dovetail on the contact pin seat is inserted into the dovetail groove on the night vision goggle host, the contact pin on the contact pin seat can enter the contact pin hole in the dovetail groove on the body of the night vision goggle host, so that the positive and negative electrodes are connected.

[0007] A further technical solution is that two left and right adjustment screws are installed on the eccentric rod, and the left and right adjustment screws are respectively connected to left and right adjustment hand wheels. The left and right adjustment hand wheels are arranged at both ends of the two left and right adjustment screws, and can be fixed on the two left and right adjustment screws by pins respectively, and rotating the left and right adjustment hand wheels can drive the corresponding left and right adjustment screws to rotate.

[0008] A further technical solution is that a thread is provided on the shaft section at one end of the eccentric rod, and a locking handwheel is installed through the thread; rotating the locking handwheel can make the locking handwheel move along the axial direction of the eccentric rod. When the locking handwheel moves along the axial direction of the eccentric rod, it will contact the housing and lock the eccentric rod through friction.

[0009] A further technical solution is that the other end of the eccentric rod is a cylinder, on which a tilting hand wheel is fixedly installed, and the eccentric rod is rotated by rotating the tilting hand wheel.

[0010] A further technical solution is that a positioning wheel is also installed on the eccentric rod, and the positioning wheel is provided with evenly distributed grooves; a spring sheet that cooperates with the positioning wheel is installed on the guide rod, and one end of the spring sheet is placed in the groove of the positioning wheel to stop the rotation of the eccentric rod.

[0011] The principle of the present invention is to use the dovetail matching method to achieve rapid installation and disassembly between the four-tube night vision goggle host and the shell of the connecting mechanism.

[0013] A thread is provided on the shaft section at one end of the eccentric rod, and the locking handwheel installed on the thread section can be rotated to make the locking handwheel move along the axial direction of the eccentric rod. When the locking handwheel moves along the axial direction of the eccentric rod, it will contact the shell and lock the eccentric rod through friction. A tilting handwheel is fixedly installed on the other end of the eccentric rod, and rotating the tilting handwheel causes the eccentric rod to rotate. Because the eccentric hole in the eccentric rod deviates from the axis, when the eccentric rod rotates, the eccentric hole will drive the left and right adjustment screws therein to swing, and then the contact pin seat installed on the left and right adjustment screws will swing. Because the contact pin seat is restricted by the guide rod, the tilt adjustment of the night vision goggle host around the guide rod is finally realized.

[0014] The housing and the front and rear adjustment bracket are installed in a dovetail fit manner, the front and rear adjustment screws are connected to the housing in a multi-threaded manner, and a front and rear adjustment hand wheel is provided at one end of the front and rear adjustment screws. Rotating the hand wheel drives the front and rear adjustment screws to rotate, and the housing can be quickly adjusted forward and backward relative to the front and rear adjustment group.

[0015] A positioning wheel with evenly distributed grooves is installed on the eccentric rod, and a spring sheet matching the positioning wheel is installed on the guide rod. One end of the spring sheet is placed in the groove of the positioning wheel. When the eccentric rod stops rotating, the spring sheet can be stuck in the groove of the positioning wheel to stop the rotation of the eccentric rod.

[0016] The above technical solution of the present invention has the following beneficial technical effects:

[0017] (1) It can realize the rapid installation, disassembly and power supply functions of the left and right night vision goggles. When the night vision goggles fail, they can be disassembled separately for maintenance.

[0018] (2) The tilt angle of the left and right night vision goggle main unit can be adjusted, a certain tilt angle can be fixed at will, and it can be manually locked. It will not loosen when affected by external forces, thereby reducing the frequency of use of the adjustment components, reducing the wear between the parts of the various mechanisms, and increasing the service life.

[0019] (3) It can realize the rapid adjustment of the left and right pupil distances of the night vision goggles separately; and the rapid adjustment function of the front and back of the night vision goggles host. BRIEF DESCRIPTION OF THE DRAWINGS
