[0023] In the disclosed embodiment, a circular deep hole is provided on the right side of the table shell 1, and a transmission rod 5 is embedded in the circular deep hole of the table shell 1. The transmission rod 5 slides to the left or right along the circular deep hole of the table shell 1. The front side of the table shell 1 is provided with two groups of rectangular grooves symmetrically distributed on the left and right. The bottom of each group of rectangular grooves is provided with a long through groove. The long through groove of the table shell 1 is connected to the circular deep hole of the table shell 1. The pushing rod 12 is embedded in the long through groove of the table shell 1. The pushing rod 12 slides left and right along the long through groove of the table shell 1. The upper and lower sides of the two groups of rectangular grooves on the front side of the table shell 1 are provided with circular hole grooves.
[0024] In the embodiment of the present disclosure, there are two groups of locking rods 6, and the two groups of locking rods 6 are respectively slidably connected to the two groups of circular hole grooves on the upper side of the rectangular groove of the table shell 1, so that the locking rods 6 support the mask 2 bonded to the front end to move in the forward and backward directions. An annular groove is provided on the outer side of the locking rod 6 near the rear end, and the lock tongue 9 penetrates into the annular groove of the locking rod 6 to limit and lock the locking rod 6, preventing the compression spring 8 from pushing the ring plate of the support guide rod 7 so that the support guide rod 7 pulls the mask 2 back to close. The locking rod 6 supports the mask 2 to remain in the open state, which is convenient for the external wire to be connected to the terminal 13.
[0025] In the embodiment of the present disclosure, the lock tongue 9 is an L-shaped structure. The upper side surface of the L-shaped structure of the lock tongue 9 is provided with a semicircular arc groove running through the front and back. The lock tongue 9 is embedded in the rectangular groove of the table shell 1. The left side and the right side surface of the lock tongue 9 are respectively attached to the left wall and the right wall of the rectangular groove of the table shell 1. The front side surface of the lock tongue 9 is attached to the rear side surface of the baffle 10. The front side surface of the lock tongue 9 is provided with an oblique through groove. The pushing rod 12 is embedded in the oblique through groove of the lock tongue 9. During the process of the pushing rod 12 moving left and right, the outer side surface of the pushing rod 12 pushes the oblique through groove wall of the lock tongue 9, so that the lock tongue 9 slides up and down along the rear side surface of the baffle 10 and the rectangular groove wall of the table shell 1, allowing the semicircular arc groove of the pushing rod 12 to penetrate into or out of the annular groove of the lock rod 6, completing the locking or unlocking work of the front and rear movement limit of the lock rod 6.
[0026] In the disclosed embodiment, the mask 2 is an inverted L-shaped structure, and twenty-eight groups of through holes are provided on the front side of the L-shaped structure of the mask 2. Each group of through holes of the mask 2 is opposite to the front and back of the terminal 13. The mask 2 covers and shields the terminal 13 to prevent processing dust and dust in the industrial environment from infecting the terminal 13. The mask 2 is made of transparent plastic material, which makes it convenient for maintenance personnel to observe the wiring status of the terminal 13 inside the mask 2.
[0027] In the disclosed embodiment, the number of rubber sleeves 3 is twenty-eight groups. The rubber sleeves 3 are bonded to the through holes of the mask 2. The front end of the rubber sleeves 3 is a necked structure. The external wires are inserted into the inner side of the rubber sleeves 3. The necked ends of the rubber sleeves 3 fit tightly to the outer side insulation surface of the external wires to prevent external fine dust from flying into the inner side of the mask 2 through the through holes of the mask 2.
[0028] The specific usage and function of this embodiment are as follows:
[0029] When the utility model is performing wiring and dust shielding work on the IO terminal block, the shield 2 is first manually pulled to overcome the elastic thrust of the compression spring 8 on the support guide rod 7 ring plate and move forward. The shield 2 pulls the locking rod 6 bonded to the rear side and moves forward synchronously along the circular hole groove of the table shell 1 until the annular groove of the outer side of the locking rod 6 close to the rear end is opposite to the arc-shaped groove on the upper side of the lock tongue 9. At this time, the return spring 11 pulls the transmission rod 5 to move to the right, and the transmission rod 5 drives the pushing rod 12 to move to the right synchronously. The outer surface of the pushing rod 12 squeezes the groove wall of the oblique through groove on the front side of the lock tongue 9, so that the lock tongue 9 moves upward, and the arc-shaped groove of the lock tongue 9 penetrates into the annular groove of the lock rod 6. The lock tongue 9 limits and locks the lock rod 6, and then releases the shield 2. The shield 2 remains fixed in this position and is completed. To open the cover 2, insert the external wire into the inner side of the rubber sleeve 3, pass the external wire through the through hole of the cover 2, and install the wire core at the end of the external wire with the wiring terminal 13. After the wiring installation is completed, manually press the button 4, and the button 4 drives the transmission rod 5 to overcome the elastic force of the return spring 11 and move to the left. The transmission rod 5 drives the pushing rod 12 to move synchronously to the left. The outer surface of the pushing rod 12 squeezes the groove wall of the oblique through groove on the front side of the lock tongue 9. At this time, the lock tongue 9 moves downward, allowing the arc-shaped slot of the lock tongue 9 to disengage from the annular groove of the lock rod 6, and then the compression spring 8 pushes the ring plate of the support guide rod 7 to move backward, and the support guide rod 7 pulls the cover 2 to move backward until the cover 2 is closed on the front side of the table shell 1, so that the cover 2 shields the wiring terminal 13 for dust protection.
