DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work belong to the range of protection of the utility model.

[0024] As Figures 1 to 5 The utility model provides a programmable controller with protection device, including programmable controller main body 1, the surface of programmable controller main body 1 is installed with protection assembly 2,

[0025] Protection assembly 2 includes protection plate 21, the surface of programmable controller main body 1 is connected with protection plate 21 slidingly, the surface of programmable controller main body 1 is installed with adjusting block 22 symmetrically, the recess of the surface of protection plate 21 is installed with connecting plate 23, adjusting block 22 is connected in the inside of connecting plate 23 slidingly, and adjusting block 22 extends to the outside of connecting plate 23 and passes through connecting plate 23, the inside of connecting plate 23 is connected with shock absorbing rubber pad 24, adjusting block 22 is pasted with shock absorbing rubber pad 24, and the surface of protection plate 21 is installed with dismounting and replacing assembly 3, so that the vibration of programmable controller main body 1 can be absorbed and handled in the process of being vibrated up and down, the internal element of programmable controller main body 1 is avoided to fall off or be damaged in the vibration process, the normal use of programmable controller main body 1 is influenced, and the shock resistance of programmable controller main body 1 is stronger.

[0026] Specifically, the surface of programmable controller main body 1 is installed with guide block 25 symmetrically, the surface of protection plate 21 is provided with guide groove 26 matched with guide block 25, and guide block 25 is connected in the inside of guide groove 26 slidingly, the cooperation of guide block 25 and guide groove 26 can guide the position of the whole movement of programmable controller main body 1, avoid the position deviation of programmable controller main body 1 in the movement process, and further improve the stability of programmable controller main body 1.

[0027] As Figures 1 to 5As shown, one end of the adjusting block 22 is provided with a damping sleeve plate 27, and the surface of the connecting plate 23 is symmetrically provided with a damping strip 28, which is in sliding connection with the damping sleeve plate 27. The damping strip 28 and the damping sleeve plate 27 can increase the resistance of the adjusting block 22, thereby avoiding the large amplitude of the programmable controller body 1, and further reducing the amplitude of the programmable controller body 1.

[0028] Further, the adjusting blocks 22 are uniformly distributed at the four corners of the programmable controller body 1, for improving the stability of the programmable controller body 1.

[0029] It is worth noting that the shock-absorbing rubber pad 24 is made of silicone rubber material, which is used for electrical insulation treatment of the programmable controller body 1.

[0030] As shown in the figure, Figures 1 to 5 The disassembly and replacement assembly 3 includes a half-threaded rod 31, and the half-threaded rod 31 is in common sliding connection with the through holes on the surfaces of the adjusting blocks 22 and the shock-absorbing rubber pad 24. The surface of the protective plate 21 is provided with a disassembly slot 32 for disassembly, and the inside of the disassembly slot 32 is provided with a nut 33. The half-threaded rod 31 is in threaded connection with the nut 33, and the nut 33 is in contact with the shock-absorbing rubber pad 24, thereby realizing the replacement of the shock-absorbing rubber pad 24. The elastic attenuation of the shock-absorbing rubber pad 24 caused by the long service period does not affect the shock-absorbing effect of the programmable controller body 1.

[0031] It is worth emphasizing that the disassembly slot 32 is located in the groove on the surface of the protective plate 21, thereby facilitating the replacement of the shock-absorbing rubber pad 24 by the operator.

[0032] Working principle and process: when the programmable controller body 1 is shaken up and down, the adjusting block 22 on the programmable controller body 1 slides in the inside of the connecting plate 23, the programmable controller body 1 slides in the inside of the protection plate 21 while being shaken up and down, the adjusting block 22 slides on the surface of the half threaded rod 31 during the sliding process, the half threaded rod 31 can guide the position of the adjusting block 22 sliding up and down, avoid the position deviation of the adjusting block 22 during the sliding process, when the programmable controller body 1 slides in the protection plate 21, the guide block 25 on the programmable controller body 1 slides in the guide groove 26 on the surface of the protection plate 21, the cooperation of the guide block 25 and the guide groove 26 can guide the position of the programmable controller body 1 moving as a whole, avoid the position deviation of the programmable controller body 1 during the moving process, further improve the stability of the programmable controller body 1, the adjusting block 22 extrudes the shock absorbing rubber pad 24 during the moving process, the shock absorbing rubber pad 24 is deformed by the extrusion force, thereby absorbing the force of the programmable controller body 1 shaken up and down, so as to avoid the damage or falling of the elements in the programmable controller body 1 during the shaking process, and because the shock absorbing rubber pad 24 is made of silicone rubber material, it can be electrically insulated, and the shock absorbing rubber pad 24 can automatically reset to the original shape, further improving the effect of the device during use.

[0033] When the adjusting block 22 slides in the connecting plate 23, the adjusting block 22 drives the damping sleeve plate 27 to slide on the surface of the damping strip 28, the damping strip 28 and the damping sleeve plate 27 can increase the resistance of the adjusting block 22, thereby avoiding the large amplitude of the programmable controller body 1 shaken up and down, further reducing the shaking amplitude of the programmable controller body 1.

[0034] When used for a long time, because the shock absorbing rubber pad 24 has a service life, the shock absorbing rubber pad 24 will lose its elasticity with time, so the operator can rotate the nut 33 threaded on the surface of the half threaded rod 31 by disassembling the slot 32, so that the nut 33 is separated from the half threaded rod 31, then pull the shock absorbing rubber pad 24 to separate it from the surface of the half threaded rod 31, thereby realizing the replacement of the shock absorbing rubber pad 24, avoiding the loss of elasticity of the shock absorbing rubber pad 24 due to long service life, affecting the shock absorbing effect of the programmable controller body 1.
