[0014] The present invention provides a radio frequency signal transmitter with a signal interference prevention function. It has the following beneficial effects:

[0015] (1) In the radio frequency signal transmitter with anti-signal interference function, the surface where the corrugation contacts the storage shell is separated, and the surface where the door-shaped plate contacts the card slot is separated when the corrugation continues to move. By holding the pull-out rod tightly, the limit imposed by the carrying tube is automatically released, which is convenient for the staff to quickly pull out the signal generating mechanism for signal debugging, thereby effectively improving work efficiency. The door-shaped plate increases the resistance encountered by the pull-out rod when it moves, so that the speed of the pull-out rod moving is slowed down under the influence of the resistance. By applying resistance, the speed of the pull-out rod moving is effectively controlled, ensuring the safety of the signal transmitting mechanism when it moves, thereby ensuring the stability of signal transmission.

[0016] (2) In the radio frequency signal transmitter with anti-signal interference function, the reaction force applied by the second spring gradually decreases, so that the clamping force applied by the rubber plate to the plug gradually decreases. The plug is automatically clamped by the clamping rod to prevent the plug from being loosened when the connection with the socket is accidentally pulled, ensuring that the signal transmitting mechanism will not be powered off due to accidental touch during operation. The arc surface three collides with the inclined surface two of the second blocking block to generate vibration, and continuous vibration is generated through the intermittent vibration of the abutment plate and the blocking block, effectively preventing the cross plate from getting stuck during movement, thereby improving the overall smoothness.

[0017] (3) The radio frequency signal transmitter with anti-signal interference function has a limit groove and a contact surface with the spherical surface separated, so that the limit imposed on the round rod by the limit block is released. The limit imposed on the round rod is released first through standardized operation. Otherwise, when the staff pulls out the signal transmitting mechanism, the plug is clamped and separated from the socket, thereby improving the standardization of operation. The mounting frame drives the limit block to move, so that the round rod cannot contact the limit block. According to different situations, the staff can actively turn off the use of the limit block, effectively improving the applicability of the limit block. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 8, one embodiment of the present invention is: a radio frequency signal transmitter with a signal interference prevention function, comprising a storage shell 1, a signal transmitting mechanism 2 is arranged inside the storage shell 1, a socket is arranged on the signal transmitting mechanism 2, a plug 3 is clamped in the socket, an air permeable plate 4 is fixedly penetrated through the inner wall of the storage shell 1, a placement groove is provided on a side of the storage shell 1 close to the plug 3, and a loading and unloading device is also included; wherein the loading and unloading device comprises a carrying tube 5, a pull rod 6, a first spring 7, a fixing plate 8, a contact plate 9, a door-shaped plate 10 and a first spring sheet 11, the carrying tube 5 is fixedly penetrated through the inner and outer walls of the storage shell 1, the pull rod 6 is slidably installed on the inner wall of the carrying tube 5, the first spring 7 is arranged between the pull rod 6 and the carrying tube 5, the fixing plate 8 is fixedly installed on the circumferential surface of the pull rod 6, and the fixing plate 8 is fixedly installed on the circumferential surface of the pull rod 6. The side of the fixed plate 8 away from the pull-out rod 6 is fixedly installed on the surface of the signal transmitting mechanism 2, the contact plate 9 is fixedly installed on the circumferential surface of the pull-out rod 6, the door-shaped plate 10 slides through the inner and outer walls of the pull-out rod 6 away from the signal transmitting mechanism 2, and the No. 1 spring plate 11 is arranged between the door-shaped plate 10 and the pull-out rod 6. A rectangular groove is provided on the side of the carrying tube 5 close to the signal transmitting mechanism 2, the fixed plate 8 contacts the inner wall of the rectangular groove, the contact plate 9 contacts the inner wall of the rectangular groove, and a card slot is provided on the side of the carrying tube 5 close to the door-shaped plate 10, and the door-shaped plate 10 contacts the inner wall of the card slot. By holding the pull-out rod 6 tightly, the limit imposed by the carrying tube 5 is automatically released, ensuring that the staff can carry out the extraction work when they are ready, and at the same time quickly extracting the signal generating mechanism 2 to effectively improve the debugging efficiency.

[0029] A corrugation 1 is provided at one end of the door-shaped plate 10 close to the carrying tube 5. The corrugation 1 contacts the inner wall of the storage shell 1. The resistance applied by the corrugation 1 effectively controls the moving speed of the pull-out rod 6, thereby preventing the signal transmitting mechanism 2 from moving too fast and causing a collision after the staff releases the pull-out rod 6, thereby ensuring the stability of the signal transmission.

[0030] The other end of the door-shaped plate 10 away from the carrying tube 5 is provided with an arc surface, and the side of the contact plate 9 away from the carrying tube 5 is provided with an inclined surface. By providing the arc surface on the door-shaped plate 10, it is ensured that the operator can easily press the door-shaped plate 10 to move toward the pull rod 6, which helps to improve the stability of use.

[0031] When the present embodiment is working, when adjusting the signal transmission channel, the staff member holds the pull rod 6 tightly, so that the staff member's hand contacts the arc surface 1, and the door-shaped plate 10 is moved toward the signal transmitting mechanism 2 by the thrust applied by the staff member's hand. The door-shaped plate 10 squeezes the No. 1 spring piece 11 during the movement, and the No. 1 spring piece 11 is squeezed and deformed. At the same time, the surface of the corrugation 1 in contact with the storage shell 1 is separated during the movement, and the door-shaped plate 10 continues to move and separates from the surface in contact with the slot, so that the limit imposed by the carrying tube 5 on the pull rod 6 is released, and the deformed No. 1 spring 7 is restored under the action of its own elasticity. The No. 1 spring 7 applies a thrust to the pull rod 6 during the restoration process, and the pull rod 6 is affected by the thrust and moves in the direction away from the carrying tube 5. The movement of the pull rod 6 drives the contact plate 9 to move in the direction away from the storage shell 1. At the same time, the movement of the pull rod 6 drives the fixed plate 8 to move in the direction away from the storage shell 1, and the movement of the fixed plate 8 drives the signal generating mechanism 2 to move in the direction away from the storage shell 1, and the signal generating mechanism 2 moves The plug 3 is driven to move in the direction of the carrying tube 5, and the limit imposed by the carrying tube 5 is automatically released by holding the pull rod 6, and then the signal transmitting mechanism 2 is pushed by the restoring force of the No. 1 spring 7, so that the staff can quickly draw out the signal generating mechanism 2 for debugging. During the movement of the signal transmitting mechanism 2, when the staff releases the pull rod 6, the deformed No. 1 spring piece 11 is restored under the action of its own elasticity. The No. 1 spring piece 11 applies a reaction force to the door plate 10 during the restoration process. The door plate 10 is affected by the reaction force and moves away from the signal transmitting mechanism 2. The corrugation 1 contacts the inner wall of the carrying tube 5 during the movement. The corrugation 1 continues to move and generates friction between the carrying tube 5. The door plate 10 increases the resistance encountered by the pull rod 6 when it moves under the action of the friction force, so that the speed of the pull rod 6 is slowed down under the influence of the resistance. The speed of the pull rod 6 is effectively controlled by the resistance applied by the corrugation 1, so as to ensure the safety of the signal transmitting mechanism 2 during movement, thereby ensuring the stability of signal transmission.

A rubber plate is fixedly mounted on the end of the clamping rod 124 away from the cross plate 122, and the rubber plate is in contact with the circumferential surface of the plug 3. The plug 3 in the storage state is stably clamped by the clamping rod 124, which effectively prevents the connection between the plug 3 and the socket from loosening when the plug 3 is accidentally pulled, thereby improving the ability of the signal transmitting mechanism 2 to cope with emergencies during operation.

[0033] The push plate 127 itself is elastic, and a curved surface 3 is provided on one side of the push plate 127 close to the blocking block 128. A spiral spring is arranged between the push plate 127 and the connecting block 126. By arranging the spiral spring between the push plate 127 and the connecting block 126, it is ensured that the push plate 127 can be smoothly reset to the initial position after rotation to prepare for the next work.

[0034] A second inclined surface is provided on one side of the blocking block 128 close to the abutment plate 127, and a spherical surface is provided on the end of the round rod 129 away from the cross plate 122.

The L-shaped rod 136 is fixedly mounted on the side of the push plate 135 close to the mounting frame 131, the docking frame 137 is fixedly mounted on the side of the loading plate 121 away from the storage shell 1, and a limiting groove is provided on the side of the limiting block 133 away from the pulling rod 132, and the limiting groove contacts the spherical surface one, and a slope three is provided on the side of the limiting block 133 close to the round rod 129. The limit of the round rod 133 is first released through standardized operation, otherwise the plug 3 will be clamped and separated from the socket when the staff pulls out the signal transmitting mechanism 2, thereby improving the standardization of the operation.

[0036] A circular hole is opened on one side of the carrying frame 131 close to the L-shaped rod 136, and the L-shaped rod 136 contacts the inner wall of the circular hole, and the L-shaped rod 136 contacts the inner wall of the docking frame 137. According to different situations, the staff can actively close the use of the limit block 133, effectively improving the applicability of the limit block 133.

[0037] When the present embodiment is working, the inclined surface 1 of the contact plate 9 is separated from the surface in contact with the arc surface 2 during the movement, and the pressure applied by the contact plate 9 to the cross plate 122 is gradually reduced, so that the deformed Z-shaped piece 123 is restored under the action of its own elasticity, and the restoration of the Z-shaped piece 123 drives the cross plate 122 to move in the direction away from the plug 3, and the movement of the cross plate 122 drives the round rod 129 to move in the direction away from the plug 3. At the same time, the cross plate 122 reduces the pressure applied to the No. 2 spring 125 during the movement, so that the deformed No. 2 spring 125 is restored under the action of its own elasticity, and the reaction force applied to the clamping rod 124 is gradually reduced when the No. 2 spring 125 is restored, so that the clamping force applied by the rubber plate to the plug 3 is gradually reduced, and after the restoration of the No. 2 spring 125 is completed, the cross plate 122 moves to drive the clamping rod 124 to move in the direction away from the plug 3, and the surface of the rubber plate on the clamping rod 124 in contact with the plug 3 is separated during the movement, and the plug 3 in the storage state is clamped by the clamping rod 124 The second inclined surface 127 and the second inclined surface 128 of the second blocking block 128 are in contact with each other during the movement, and the second inclined surface 128 is in contact with the third curved surface 127 of the second blocking block 128. The second inclined surface 127 is in contact with the third curved surface 127 of the second blocking block 128, and the second inclined surface 128 is in contact with the third curved surface 127 of the second blocking block 128.

[0038] When the round rod 129 moves toward the plug 3, the spherical surface 1 contacts the inclined surface 3 during the movement, so that the round rod 129 continues to move and applies a thrust to the limit block 133. The limit block 133 is affected by the thrust and moves in a direction away from the round rod 129. The movement of the limit block 133 drives the pulling rod 132 to move in a direction away from the round rod 129. At the same time, the limit block 133 squeezes the second spring piece 134 during the movement. When the spherical surface 1 moves to the predetermined position, the surface in contact with the limit block 133 is separated, so that the thrust applied by the round rod 129 to the limit block 133 The second spring piece 134 is gradually reduced, and the deformed second spring piece 134 is restored to drive the limit block 133 to move toward the round rod 124. The limit groove of the limit block 133 contacts the spherical surface during the movement, so that the limit block 133 limits the movement of the cross plate 122. Before extracting the signal transmitting mechanism 2, the staff needs to perform a specified operation to release the limit of the cross plate 122, and manually hold the pull rod 132 to move away from the mounting frame 131. The movement of the pull rod 132 drives the limit block 133 to move toward the mounting frame 131, and the limit block 133 During the movement, the second spring piece 134 is squeezed, and the limiting groove is separated from the contact surface of the spherical surface during the movement, so that the limiting block 133 is released from the round rod 133. The limiting of the round rod 133 is first released through standard operation, otherwise the plug 3 is clamped and separated from the socket when the staff pulls out the signal transmitting mechanism 2, thereby improving the standardization of the operation. When the staff operates alone, it is necessary to actively turn off the function of the limiting block 133 and push the push plate 135 to move in the direction of the pulling rod 132. The push plate 135 moves to drive the L-shaped rod 136 Move in the direction of the pulling rod 132, and the L-shaped rod 136 is separated from the inner wall of the docking frame 137 during the movement, so that the limit imposed by the docking frame 137 on the carrying frame 131 is released, and the carrying frame 131 is pulled to move in the direction away from the loading plate 121. The movement of the carrying frame 131 drives the limit block 133 to move in the direction away from the round rod 129, so that the round rod 129 cannot contact the limit block 133 during the movement. According to different situations, the staff can actively turn off the use of the limit block 133, which effectively improves the applicability of the limit block 133.
