Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses an injection molding machine protection curtain, including the steel sheet 2 of the L type of fix with screw on injection molding machine crossbeam 1 bottom surface. The existing injection molding machine is provided with a manipulator, and the mechanical operation is adopted, so that the production efficiency can be improved, and the production cost can be reduced. For preventing that the staff from inadvertently hitting the manipulator, seted up a plurality of mounting holes 21 along steel sheet 2's length direction equidistance on steel sheet 2's surface, all installed a protection chain ring 3 in every mounting hole 21, a plurality of protection chain rings 3 have formed the protection curtain along vertical direction drooping, and the protection curtain warns the staff and need not continue to be close to the injection molding machine, prevents that the staff from hitting the manipulator, improves staff's operational safety nature. The protective chain ring 3 comprises a chain ring unit 31 and a connecting ring 32 for connecting the chain ring unit 31 with the mounting hole 21, the connecting ring 32 is made of stainless steel, the chain ring unit 31 is sequentially connected in series along the vertical direction, and the chain ring unit 31 can be made of plastic.

Referring to fig. 1 and 2, in order to facilitate the worker to mount the protective chain ring 3 into the mounting hole 21, the connection ring 32 includes an upper ring 321 engaged with the mounting hole 21 and a lower ring 322 integrally formed with one end of the upper ring 321, and a connection portion 323 is connected between the upper ring 321 and the lower ring 322, and the connection portion 323 is cylindrical. One end of the connecting portion 323 is hinged to the lower ring 322, and the connecting ring 32 is further provided with a fixing assembly for fixing the connecting portion 323. When the protective chain ring 3 is installed, the connecting part 323 is rotated around the hinged part, so that a gap exists between the connecting part 323 and the upper ring 321, and then the connecting ring 32 is sleeved into the installation hole 21, so that the installation is convenient and quick. Finally, the connecting portion 323 is fixed by a fixing component, so that the connecting portion 323 can not rotate around the hinge, and no gap is left between the connecting portion 323 and the upper ring 321.

Referring to fig. 2 and 3, the fixing assembly includes a first sleeve 4 with an internal thread, which is sleeved on the lower ring 322, and the internal diameter of the first sleeve 4 is equal to the external diameter of the connecting portion 323. The outer wall of the connecting portion 323 near the hinged end is provided with a first thread 41 for engaging with the first sleeve 4. One end of the upper ring 321 close to the connecting part 323 is sleeved with a second sleeve 7 with internal threads, and the outer wall of the connecting part 323 far away from the hinged end is provided with second threads 8 matched with the second sleeve 7. After the attachment of the connection ring 32 is completed, the connection part 323 is rotated around the hinge so that the connection part 323 can be seamlessly abutted with the upper ring 321, the first sleeve 4 is rotated, and the first sleeve 4 is clamped at the hinge of the connection part 323, so that the connection part 323 is limited to rotate around the hinge point. After the first sleeve 4 hoops the hinge joint, the second sleeve 7 is rotated downwards, so that the second sleeve 7 hoops the joint between the upper ring 321 and the connecting portion 323, the connecting portion 323 is further limited to rotate around the hinge joint, and seamless connection between the connecting portion 323 and the upper ring 321 is achieved.

Referring to fig. 2 and 3, in order to facilitate the worker to rotate the first sleeve 4, a rubber pad 42 is sleeved on the circumferential surface of the first sleeve 4, and the rubber pad 42 increases the friction force between the hand of the worker and the first sleeve 4. When the second sleeve 7 is located on the upper ring 321 and the connecting portion 323 is also in the open state, in order to prevent the second sleeve 7 from sliding down along the upper ring 321, a third thread 9 matching with the second sleeve 7 is provided on the circumferential surface of the upper ring 321. The second sleeve 7 is fixed to the upper ring 321 by the cooperation between the third screw thread 9 and the second sleeve 7, preventing the second sleeve 7 from slipping off the upper ring 321.

Referring to fig. 3 and 4, in order to make the connection between the upper ring 321 and the connection portion 323 more tight, a protrusion 5 is connected to one end of the connection portion 323 near the upper ring 321, and the protrusion 5 and the connection portion 323 are integrally formed. One end of the upper ring 321 close to the connecting portion 323 is provided with a groove 6 which is engaged with the bump 5. The top surface of the bump 5 is embedded with a magnetic piece 51, and the inner wall of the groove 6 is embedded with an adsorption piece 61 magnetically attracted with the magnetic piece 51. In this embodiment, the magnetic member 51 is a magnet, and the adsorbing member 61 is an iron sheet. When fixing connecting portion 323, around articulated department swivelling joint portion 323 for in connecting portion 323's the lug 5 inlay card recess 6, because inhale the appeal between 51 and the absorption piece 61 of magnetism, connecting portion 323 is when docking with last ring 321, connect more closely, thereby realize connecting portion 323 and the seamless butt joint of last ring 321, accomplish connecting portion 323's fixed, further restrict connecting portion 323 and rotate around the pin joint.

The implementation principle of the embodiment is as follows: when the protective chain ring 3 is installed, the connecting part 323 is rotated around the hinged part, so that a gap exists between the connecting part 323 and the upper ring 321, and then the connecting ring 32 is sleeved into the installation hole 21, so that the installation is convenient and quick.

Then, the connecting portion 323 is rotated around the hinge joint, so that the protrusion 5 of the connecting portion 323 is inserted into the groove 6, and due to the attraction between the magnetic attraction member 51 and the attraction member 61, the connecting portion 323 is connected more tightly when being butted with the upper ring 321, thereby achieving the primary fixation of the connecting portion 323 and the upper ring 321.

Finally, the first sleeve 4 is rotated, and the first sleeve 4 hoops at the hinge of the connecting part 323, so that the connecting part 323 is limited to rotate continuously around the hinge point. After the first sleeve 4 hoops the hinge joint, the second sleeve 7 is rotated downwards, so that the second sleeve 7 hoops the joint between the upper ring 321 and the connecting portion 323, the connecting portion 323 is further limited to rotate around the hinge joint, and seamless connection between the connecting portion 323 and the upper ring 321 is achieved.

The protective chain ring 3 is vertically dropped to form a protective curtain, the protective curtain warns workers not to continuously approach the injection molding machine, the workers are prevented from colliding the mechanical arm, and the operation safety of the workers is improved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
