[0019] like Figure 2As shown, the key body includes a key 101 and a key clamp, and the key clamp includes a clamp body 102. The front side of the clamp body 102 is the entrance of the key handle. The left and right sides and the rear side of the clamp body 102 are respectively provided with an elastic wall. When the key handle is inserted into the clamp body 102, the two sides and the rear end of the key handle respectively abut against an elastic wall to achieve the clamping and fixing of the key.
[0020] Specifically, Figure 3 As shown, the key clamp includes a clamp body 102, a left side wall 104, a right side wall 110, a rear wall 114, a left limit plate 105, a right limit plate 109, a rear limit plate 113, a left clamp plate 107, a right clamp plate 108, a rear clamp plate 111, a side telescopic spring 106, and a rear telescopic spring 112. The backs of the left clamp plate 107, the right clamp plate 108, and the rear clamp plate 111 are respectively vertically connected with three push rods, and the push rods pass through the push rod through holes on the left limit plate 105, the right limit plate 109, and the rear limit plate 113. The side telescopic spring 106 is sleeved on the push rod between the left clamp plate 107 and the left side wall 104, and the push rod between the right clamp plate 108 and the right side wall 110, and the rear telescopic spring 112 is sleeved on the push rod between the rear clamp plate 111 and the rear limit plate 113. The left side wall 104, the right side wall 110, and the rear wall 114 are fixedly connected to the clamp body 102 through a pin. A groove 103 is provided on the outer side of the right side wall 110. The left clamp plate 107 and the right clamp plate 108 are provided with opposite inclined surfaces near the key handle entrance side of the clamp body 102. The left clamp plate 107, the right clamp plate 108, and the rear clamp plate 111 are elastically connected through the side telescopic spring 106 and the rear telescopic spring 112 respectively.
[0021] The handle of the key 101 is inserted into the clamp body 102, and the left clamp plate 107, the right clamp plate 108, and the rear clamp plate 111 respectively provide clamping force through the side telescopic spring 106 and the rear telescopic spring 112, so as to clamp and fix the handle of the key 101, and adjust according to the shape of the handle of different keys 101, so as to fix and protect the key and prevent the key from falling off or sliding.
[0022] The switch device includes a button 301, a sliding cam 302, and a locking mechanism 304. When the key body is inserted into the key receiving slot, the locking mechanism 304 is embedded in the groove 103 of the side wall of the key clamp through the wedge-shaped buckle 308 for locking, and the sliding cam 302 is operated by the button 301 to drive the locking mechanism 304 to move, thereby releasing the lock between the key and the switch device.
[0023] Specifically, Figure 4As shown, the key storage slot includes a storage slot 209 of the key body 101, a limit slot 208 of the clamp body 102, and a positioning slot 202 of the switch device. The entrance of the storage slot 209 is connected to the limit slot 208, and the entrance of the limit slot 208 is connected to the positioning slot 202; a button through hole 205 is provided on the outer end surface of the positioning slot 202.
[0024] like Figure 5 As shown, the locking mechanism 304 is a square frame structure, and the wedge-shaped buckle 308 is arranged on the inner side of the left side of the square frame structure. Figure 6 , Figure 7 As shown, the locking mechanism 304 is embedded in the positioning groove 202, and the left side of the frame structure is connected to the positioning surface 203 on one side of the positioning groove 202 through a reset spring 305. A cam groove 212 is provided on the side of the positioning groove 202 opposite to the positioning surface 203, and the sliding cam 302 is arranged in the cam groove 212. The button 301 is fixedly connected to the wide end of the sliding cam 302 through the button through hole 205, and the narrow end of the sliding cam 302 is connected to one end of the cam spring 303 in the cam groove 212; when the button 301 is pressed inward, the narrow-to-wide portion of the sliding cam 302 pushes the locking mechanism 304 to compress the reset spring 305 to move.
[0025] The key storage slot also includes push rod slots 210 symmetrically arranged on both sides of the storage slot 209, and a push rod through hole is provided on the limiting wall 211 at the end of each push rod slot 210. The switch device also includes two push rods 309 and two ejection plates 306. The push rods 309 in each push rod slot 210 are slidably connected to the push rod through hole, and an ejection spring 307 is sleeved on each push rod 309. The end of the push rod located in the limiting slot 208 is connected to the ejection plate 306, and the ejection plate 306 is elastically connected to the limiting wall 211 through the ejection spring 307.
[0026] The assembled key body can be inserted into the key storage slot along the container slot 209. During the insertion process, the key body will be precisely connected with the limit slot 208, the container slot 209 and other slots inside the storage box. The connection between the key body and the storage box is achieved by the wedge-shaped buckle 308 cooperating with the right side wall 110. Figure 8 When the key body is inserted into the storage box, the locking mechanism 304 is laterally displaced in the positioning groove 202 by the elastic force of the return spring 305 on the locking mechanism 304, and the wedge-shaped buckle 308 is inserted into the groove 103 on the right side wall 110 to lock the key body, thereby locking the key body to prevent it from sliding out.
[0027] When the key needs to be taken out, the button 301 is pressed, and the sliding cam 302 is connected to the button 301 through the button through hole 205, pushing the locking mechanism 304 to unlock. The sliding cam 302 drives the locking mechanism to move laterally along the positioning groove 202, compressing the return spring 305, so that the wedge-shaped buckle 308 is separated from the groove 103, and the locked state is released. At this time, the ejection plate 306, under the action of the ejection spring 307, pushes the key body to eject a distance from the storage groove 209, so that it is easy for the user to take it out.
[0028] like Fig. 9 As shown, a plurality of filling blocks 217 and a plurality of fastening pins 221 are evenly spaced along the circumference on the inner bottom surface of the cover 201. Each filling block 217 is used to fill the space at the top of the key storage slot to assist in clamping the key body. The fastening pins 221 are used to be inserted into the vertical holes 207 on the storage box body to fasten the connection between the cover 201 and the storage box body.
[0029] like Figure 4 As shown, a handle 215 is provided in the middle of the annular storage box body, and the user can conveniently extract or move the storage box through the handle. A square hole 216 is provided in the middle of the handle 215, which is convenient for carrying with a rope or for fixing multiple storage boxes together, so as to facilitate long-term carrying and storage. Example
[0030] like Fig.10 As shown, the bottom surface of the storage box is provided with a plurality of tightening grooves 204; Fig.11 As shown, a plurality of tightening buckles 220 that can be locked with the tightening groove 204 are provided on the top surface of the cover 201. Multiple storage boxes can be connected together by tightening buckles 220 and tightening grooves 204 to form a multi-layer storage box to achieve a larger storage capacity. When the user no longer needs multiple storage boxes, the storage boxes can be separated by rotating the tightening buckles 220 for easy disassembly. After disassembly, a single storage box can still provide enough space to meet daily use. Since the storage boxes are stackable and have adjustable space, users can flexibly expand or reduce the storage space according to actual needs to meet the storage needs of different numbers of keys.
[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
