Specifically, the adapter unit 1 in the preferred embodiment is as shown in fig. 1 to 3, and includes a body 101 in a box-like or block-like structure, wherein the bottom of the body 101 is used for matching with the slide rail 3, and the top of the body 101 is used for matching with the object to be launched, so that the body 101 can slide along the slide rail 3 after matching with the object to be launched.

Referring to the illustration in fig. 3, the body 101 in the preferred embodiment is provided with a slider 102 and a slider box 103 in mating relationship. The slider box 103 is mounted in the body 101 through a mounting plate 105, and a slide coaxial with the unlocking mechanism 2 is formed in the slider box 103, so that the slider 102 embedded in the slider box 103 can reciprocate in the axial direction of the unlocking mechanism 2. Accordingly, the slider 102 in the preferred embodiment is provided with a locking pin 104 in the vertical direction as shown in fig. 6 and 7, so that the locking pin 104 can be extended and retracted in the axial direction of the slider 102 in a reciprocating manner when the slider is moved from one end to the other end.

In actual arrangement, one end of the locking pin 104 matches the slider 102, and the other end extends out of the top of the body 101; accordingly, a receiving groove is provided at one side of the object-to-be-emitted matching adapter unit 1 so that the end of the locking pin 104 protruding from the top of the body 101 can be fitted into the receiving groove, thereby achieving locking matching of the two.

More specifically, the slider 102 in the preferred embodiment is a cylindrical structure with openings at the upper and lower sides, and a chute 1021 extending obliquely is opened on the outer peripheral wall surface thereof, and a guide pin 1022 is correspondingly disposed in the chute 1021, such that one end of the guide pin 1022 is connected to the locking pin 104, and the other end is embedded in the chute 1021. One end of the locking pin 104 extends out of the through hole vertically extending on the body 101, so that the horizontal relative position of the locking pin 104 and the body 101 is always kept unchanged; thus, when the slider 102 slides horizontally, the guide pin 1022 can move in the sliding groove 1021, and slide from one end of the sliding groove 1021 to the other end of the sliding groove 1021, because of the vertical height difference between the two ends of the sliding groove 1021. Accordingly, the locking pins 104 can perform a vertical elevating movement following the guide pins 1022 while the guide pins 1022 are slid, thereby completing the elevating control of the locking pins 104.

More specifically, the slider 102 in the preferred embodiment is a square tubular structure as shown in fig. 6, and the sliding grooves 1021 are arranged on two sides of the slider 102 in pairs; accordingly, the guide pins 1022 are also provided in two parts on both sides of the locking pin 104, and are respectively inserted into the corresponding slide grooves 1021 at the ends. Meanwhile, the two sliding grooves 1021 are preferably of a three-stage structure, i.e., end portions located at both ends and having a height difference with each other, and a middle portion located between both ends and extending obliquely, as shown in fig. 6. In addition, the vertical height of the sliding groove 1021 at one end close to the unlocking mechanism 2 is lower than that at the other end, so that when the guide pin 1022 moves from one end away from the unlocking mechanism 2 to one end close to the unlocking mechanism 2, the locking pin 104 can be switched from a state that the end part extends out of the top surface of the body 101 to a state that the end part does not protrude out of the top surface of the body 101, and the locking state and the unlocking state of the locking pin 104 can be switched.

It is understood that, besides the above structural forms, the matching form between the locking pin 104 and the sliding block 102 in the preferred embodiment may be set to another form, for example, a combination form of "screw pair + rack and pinion", in this case, the sliding block 102 is a gear structure sleeved on the outer periphery of the end of the guiding shaft 201, and the two form the screw pair; correspondingly, the end of the locking pin 104 is provided with a toothed plate structure matched with the peripheral "gear" of the sliding block 102, the two are meshed to form a "gear rack" combination form, horizontal sliding is realized by utilizing the rotation of the sliding block 102 relative to the guide shaft 201, and the telescopic control of the locking pin 104 is realized in the process. Of course, in addition to the above forms, the matching form of the locking pin 104 and the slider 102 may be set to other forms as long as the sliding of the slider 102 can drive the telescopic movement of the locking pin 104, and the details are not described herein.

Further, as shown in fig. 3 to 5, the unlocking mechanism 2 in the preferred embodiment includes a guide shaft 201 disposed parallel to the slide rail 3, and a sleeve holder 202 is coaxially disposed corresponding to the guide shaft 201. Wherein one end of the sleeve seat 202 is connected to the body 101, and correspondingly, one end of the guide shaft 201 coaxially penetrates into the sleeve seat 202 and is connected with one end of the slide block 102. In this way, the slide 102 can be driven to move by the reciprocating movement of the guide shaft 201 relative to the sleeve holder 202. In actual implementation, the end of the sleeve mount 202 preferably extends into the body 101 and connects to one side of the slider box 103.

Meanwhile, a limiting protrusion 204 is circumferentially disposed on an outer periphery of an end portion of the guide shaft 201 extending out of the sleeve base 202, and is further preferably in a form of a "convex ring" as shown in fig. 5, for limiting an end portion of the elastic member 203 sleeved on one side of the limiting protrusion 204. In a preferred embodiment, one end of the elastic member 203 abuts on the limiting protrusion 204, and the other end abuts on the end surface of the sleeve seat 202, so that when the guide shaft 201 extends into the sleeve seat 202, the elastic member 203 can correspondingly compress and store energy. By means of the arrangement of the elastic piece 203, the reliability of the initial state of the unlocking mechanism 2 can be guaranteed, and accidental starting of the retained adapter is avoided.

Meanwhile, one end of each baffle is rotatably connected in the embedding groove, and the other end of each baffle rotatably extends out of the notch of the embedding groove, namely the other end of each baffle rotatably extends out of the surface of the guide shaft 201.

It will be appreciated that in actual deployment, the second stop 207 is positioned to extend into the end of the sleeve mount 202; in contrast, two locking grooves are formed in the inner peripheral wall surface of the sleeve holder 202 at intervals in the axial direction, and are used for fitting the free end of the second shutter 207. In the preferred embodiment, two locking slots extend through the inner and outer wall surfaces of the sleeve mount 202, respectively, as shown in FIG. 5.

Also, the two baffles in the preferred embodiment are preferably in the form of "triangular" wedges as shown in fig. 5, and spring return members 209 are provided below the free ends of the two baffles, the spring return members 209 providing an outward force to the respective baffles such that the free ends of the baffles always extend out of the notches of the receiving slots. Of course, when the free end of each baffle is applied with a radially inward force, the elastic force of the elastic restoring piece 209 can be overcome and the whole baffle is accommodated in the embedding groove.

In the preferred embodiment, the spring return 209 is a leaf spring secured beneath both of the baffles, as shown in FIG. 5. Meanwhile, the two baffles in the preferred embodiment are respectively connected in the embedding groove in a rotating way by the shaft pins 208; accordingly, an end portion of the shaft pin 208 connected to the second shutter 207 protrudes from an outer circumferential wall surface of the guide shaft 201, and a guide groove is axially opened on an outer circumference of an end portion of the sleeve holder 202 corresponding to the end portion of the shaft pin 208, so that the end portion of the shaft pin 208 can be correspondingly inserted into the guide groove and move in the guide groove when the guide shaft 201 slides with respect to the sleeve holder 202. By means of the corresponding arrangement of the shaft pin 208 and the guide groove on the sleeve seat 202, the axial extension reliability of the guide shaft 201 can be ensured, and the relative rotation of the guide shaft 201 during extension and retraction can be avoided.
