Description

Technical Field

[0001] The utility model relates to the technical field of electronic tags, in particular to a fixed electronic tag reader / writer. Background Art

[0002] An RFID reader / writer is a device that can read and write RFID tag information. It is typically used in scenarios such as supply chain management, inventory tracking, production line automation, airline baggage handling, and security tracking to improve the efficiency and accuracy of data collection. A fixed RFID reader / writer is a fixed-mounted RFID reader / writer.

[0030] Reference Figures 1-4 , is an embodiment of the present utility model, which provides a fixed electronic tag reader / writer, comprising:

[0031] The main body 100 includes a reader body 101 and a plug-in block 102 fixedly connected to the rear side of the reader body 101. The plug-in block 102 has a pin hole 102a formed on its side wall.

[0032] The shock-absorbing mounting assembly 200 includes a mounting plate 201, a housing 202, a shock-absorbing spring 203, a movable slat 204, a connecting post 205, and a mounting block 206. The mounting plate 201 is disposed on the rear side of the reader / writer body 101. The housing 202 is fixedly connected to the mounting plate 201. The movable slat 204 is movably disposed within the housing 202. Six groups of shock-absorbing springs 203 are equidistantly disposed around the movable slat 204 between the movable slat 204 and the housing 202. Both ends of the six groups of shock-absorbing springs 203 are respectively fixedly connected to the housing 202 and the movable slat 204. The connecting post 205 is fixedly connected to the top of the movable slat 204. The top of the housing 202 is provided with an opening through which the connecting post 205 passes. The mounting block 206 is fixedly connected to the top of the connecting post 205. The top of the mounting block 206 is provided with a slot 206a that fits with the plug-in block 102. The plug-in block 102 is inserted into the slot 206a.

[0033] The locking mechanism 300 is arranged on one side of the mounting block 206 and is used to cooperate with the pin hole 102a to lock the plug-in block 102. The locking mechanism 300 includes a locking pin 301, a return spring 302 and a connecting plate 303. A through hole that fits the locking pin 301 is opened at a position of the mounting block 206 opposite the pin hole 102a. The locking pin 301 passes through the through hole and is inserted into the pin hole 102a. The connecting plate 303 is arranged on the outside of the mounting block 206 and is fixedly connected to the locking pin 301. The return spring 302 is sleeved on the outside of the locking pin 301. The two ends of the return spring 302 are respectively fixedly connected to the locking pin 301 and the connecting plate 303;

[0034] Among them, the top of the movable slat 204 fits with the top inner wall of the shell 202, and the bottom of the mounting block 206 fits with the top of the shell 202, so as to prevent the reader body 101 from shaking and ensure the stability of the device structure. The sizes of the movable slat 204 and the mounting block 206 are both larger than the size of the opening of the shell 202, and the size of the connecting column 205 is smaller than the size of the opening of the shell 202.

[0035] In addition, the locking pin 301 is also equipped with a pull ring 304, which is fixedly connected to the end of the locking pin 301 away from the mounting block 206. The pull ring 304 is used to facilitate pulling the locking pin 301. The size of the locking pin 301 matches the size of the pin hole 102a, which can prevent the plug-in block 102 from shaking. The surface of the locking pin 301 is smooth, which helps reduce friction and facilitates the insertion and removal of the locking pin 301.

[0036] It should be noted that the outer edge of the pin hole 102a has a chamfer, and the end of the locking pin 301 close to the plug-in block 102 has a chamfer. The chamfer is used to facilitate the insertion and removal of the locking pin 301 and reduce the precision requirements of components. The axes of the movable slat 204, the connecting column 205 and the mounting block 206 are arranged to coincide with each other. The surfaces of the shell 202, the movable slat 204 and the mounting block 206 are rough, which is conducive to improving the stability of the device.

[0037] Working Principle: When the reader / writer body 101 is hit, the impact causes the reader / writer body 101 and the plug-in block 102 to deflect. The plug-in block 102 drives the mounting block 206 to deflect, and the mounting block 206 drives the movable slat 204 to deflect via the connecting column 205. When the movable slat 204 deflects, the groups of shock-absorbing springs 203 on the deflected side are compressed, while the remaining shock-absorbing springs 203 extend. The six groups of shock-absorbing springs 203 work together to cushion the impact and prevent damage to the reader / writer body 101. After the impact, the six groups of shock-absorbing springs 203 work together to quickly stabilize the movable slat 204.

[0038] When the reader / writer body 101 needs to be disassembled and maintained, the locking pin 301 is pulled outward through the pull ring 304 to disengage the locking pin 301 from the pin hole 102a. At this time, the plug-in block 102 can be pulled out of the slot 206a, and the reader / writer body 101 can be pulled out. After taking out the reader / writer body 101, the pull ring 304 is released, and the reset spring 302 pulls the locking pin 301 to reset through the connecting plate 303.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
