DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0032] Reference Figures 1 to 9 As shown, the embodiment of the utility model provides a spring locking device on an optical element carrier, comprising:

[0033] The limiting body 100 includes a U-shaped member 110, and the inner wall of the top of the U-shaped member 110 is provided with a protrusion 120 protruding inwardly;

[0034] The lock body 200 includes a main body 210, a telescopic assembly 220 and two lock tongues 230; the main body 210 includes a front plate 211, a back plate 212, a left plate 213, a right plate 214, an upper cover 215 and a lower cover 216; a mounting cavity 217 is provided in the main body 210, and side holes 218 are symmetrically provided on the left plate 213 and the right plate 214; an opening 219 is provided on the top of the main body 210; the telescopic assembly 220 includes a telescopic member 221 and a ejector pin 222 connected to the bottom end of the telescopic member 221, and the bottom of the telescopic assembly 220 extends from the opening 219 into the mounting cavity 217; and the ejector pin 222 is located in the mounting cavity 217; the telescopic assembly The member 220 drives the ejector pin 222 to extend and retract in the installation cavity 217; two locking tongues 230 are symmetrically arranged in the installation cavity 217, and the locking tongue 230 includes a body 231 and a clamping portion 232 connected to the outside of the body 231; the body 231 is rotatably connected to the front plate 211 and the back plate 212, the rotation axis of the body 231 is perpendicular to the back plate 212, and the locking tongue 230 rotates around its rotation axis in a plane parallel to the back plate 212; the ejector pin 222 is located between the two locking tongues 230, and the ejector pin 222 extends and retracts up and down to drive the body 231 to rotate so that the clamping portion 232 is retracted from the side hole 218 into the installation cavity 217 or extends out of the body 210;

[0035] The main body 210 is located in the U-shaped member 110 , and the clamping portion 232 extends out and is clamped on the bottom of the protrusion 120 .

[0036] Specifically, the present embodiment is provided with a telescopic assembly 220, and the top of the telescopic assembly 220 is docked with the manipulator to realize automatic driving of the telescopic assembly 220 to telescope so that the ejector pin 222 moves up and down, thereby driving the clamping portion 232 of the lock tongue 230 to extend and lock with the protrusion 120 of the limiting body 100 or driving the clamping portion 232 of the lock tongue 230 to retract and unlock with the limiting body 100. It can be seen that the present application can dock with the manipulator to realize automatic locking and unlocking, and the structure is stable and reliable. In addition, the limiting body 100 and the lock body 200 in the present embodiment are frame structures that are not easily damaged, which ensures the sealing of the carrier while further realizing the stability and reliability of its cooperation with the manipulator.

[0037] Furthermore, the bottom of the ejector pin 222 is V-shaped, and two side surfaces of the V-shape cooperate with the two locking tongues 230 respectively.

[0038] Specifically, the V-shaped design in this embodiment reduces the space occupied by the installation cavity 217 while ensuring that the ejector pin 222 can drive the two locking tongues 230 to extend or retract synchronously after cooperating with the two locking tongues 230, so that the operation is more stable and reliable.

[0039] Furthermore, the lock body 200 further includes two reset members 240, which are arranged one by one with the lock tongue 230. The ejector pin 222 moves upward, and the body 231 is driven by the reset member 240 to rotate and retract. The reset member 240 is a torsion spring; the body 231 is rotatably connected with the front plate 211 and the back plate 212 through a pin shaft, and the torsion spring is sleeved on the pin shaft and located at one end of the body 231; one end of the torsion spring is mounted on the side wall of the installation cavity 217. In some embodiments, a pin hole is provided on the body 210, and one end of the torsion spring is inserted into the pin hole, so as to realize the connection between the body 210 and the torsion spring. The other end of the torsion spring is connected to the body 210. For example, the torsion spring is sleeved on the front side of the pin shaft, and one end of the torsion spring is mounted on the inner wall of the front plate 211; for another example, the torsion spring is sleeved on the back side of the pin shaft, and one end of the torsion spring is mounted on the inner wall of the back plate 212.

[0040] Specifically, the reset member 240 in this embodiment enables the locking tongue 230 to be automatically reset and retracted, and has a simple structure and stable operation.

[0041] Furthermore, a locking tongue roller 233 is rotatably connected to a position in the body 231 of the locking tongue 230 that cooperates with the ejector pin 222 , and a rotation axis of the locking tongue roller 233 is parallel to the rotation axis of the locking tongue 230 .

[0042] Specifically, the locking tongue roller 233 in this embodiment enables the ejector pin 222 and the locking tongue 230 to have rolling friction, thereby reducing wear.

[0043] Furthermore, a guide wheel 121 is rotatably connected to the protrusion 120 , and a rotation axis of the guide wheel 121 extends forward and backward.

[0044] Specifically, the guide wheel 121 in this embodiment rotates relative to the limiting body 100 , so that when the lock body 200 is buckled into the limiting body 100 , the guide wheel 121 plays an auxiliary guiding role.

[0045] Furthermore, the front plate 211 and the back plate 212 are symmetrically provided with ejector slide rails 223 extending up and down, and the ejector 222 and the ejector slide rails 223 form a sliding pair.

[0046] Specifically, the ejector slide rail 223 in this embodiment serves as a guide for the ejector 222 to move up and down.

[0047] Furthermore, the telescopic component 220 is an elastic pressing component, and the ejector pin 222 is moved downward and extended and moved upward and reset by pressing the top of the elastic pressing component. The elastic pressing component in this embodiment is the same as the structure of elastic pressing to extend and retract the ballpoint pen. The specific structure can refer to the press-and-pop structure of the press-type writing pen, and will not be described in detail here. The top of the telescopic component 220 is a pressing handle 224, which is located outside the main body 210.

[0048] When the present application is in the folded state: the pressing handle 224 is pressed to drive the ejector pin 222 to be ejected along the ejector slide rail 223, and the ejector pin 222 squeezes the lock tongue rollers 233 on both sides of the ejector pin 222 to make the lock tongue 230 extend out of the lock body 200, and the reset member 240 is compressed synchronously to make it enter the compressed energy storage state, and at the same time, the elastic pressing component enters the locked state and is locked, so that the ejector pin 222 cannot move backward to keep the lock tongue 230 in the extended state, so that the spring lock device enters the locked state.

[0049] When the present application is in the locked state: press the pressing handle 224 again, the elastic pressing component moves downward to disengage the locked state, and after releasing the pressing handle 224, the ejector pin 222 moves upward under the action of the reset member 240, so that the ejector pin 222 also disengages from the lock tongue roller and moves upward to 233, and the lock tongue 230 is retracted into the lock body 200 under the action of the reset member 240, and the spring locking device enters the retracted state.

[0050] Furthermore, the U-shaped member 110 includes a bottom plate 111 and side components 112 connected to the left and right sides of the bottom plate 111 ; the protrusion 120 is disposed on the inner wall of the top of the side component 112 .

[0051] Further, the lock body 200 is provided with a plurality of first fixing pin holes 250; the limiting body 100 is provided with a plurality of second fixing pin holes 130. The carrier includes a carrier top cover and a carrier bottom plate. The carrier top cover and the carrier bottom plate need to be sealed and buckled by a plurality of spring locking devices. The first fixing pin hole 250 of the lock body 200 is connected to the carrier top cover by bolts; the second fixing pin hole 130 of the limiting body 100 is connected to the carrier bottom plate by bolts.

[0052] When the lock body 200 is buckled into the limiting body 100, by pressing the pressing handle 224 on the top of the lock body 200, the lock tongue 230 of the lock body 200 pops out and snaps into the bottom of the guide wheel 121 of the limiting body 100, so that the spring lock device completes the locking state.

[0053] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
