DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0029] like Figure 1-Figure 2 As shown, the utility model proposes a large circular knitting machine protection device, which includes a mounting frame 1, a pair of parallel fixing plates 10 are respectively arranged on the left and right sides of the mounting frame 1, a central axis 11 is arranged between each pair of fixing plates 10, and a protection door 2 is movably arranged on the two central axes (11), and the two protection doors 2 are connected by a locking device 3.

[0030] like Figure 3 As shown, a plurality of mounting holes 12 are provided on both sides of the mounting frame 1 , and bolts 13 are provided in the mounting holes 12 .

[0031] As an optimization solution of the present invention, bolts 13 are arranged through the mounting holes 12 so that the present invention can be fixed to the outside of the large circular knitting machine.

[0032] like Figure 4 As shown, the protective door 2 is provided with a plurality of heat dissipation holes 20 , and the protective door 2 is also provided with a handle 21 .

[0033] As an optimization scheme of the utility model, by setting the heat dissipation hole 20, it can prevent the large circular knitting machine from being damaged due to excessive temperature after working for a long time, so that it can effectively dissipate heat

[0034] like Figure 5 As shown, the holding device 34 includes a top block 340 fixedly arranged at one end of the latch rod 32 , a plurality of holding springs 341 are arranged on the top block 340 , a clamping block 342 is connected to the holding spring 341 , and the clamping block 342 can extend the elastic movement of the latch rod 32 .

[0035] like Figure 6-Figure 10 As shown, in the holding device 34, a top block 340 is arranged at one end of the latch rod 32, and a plurality of holding springs 341 are arranged on the top block 340, and a clamping block 342 is connected to the holding spring 341, and the clamping block 342 is movably arranged on the latch rod 32; the self-locking device 31 includes a fixed block 315 arranged in the installation groove 33, and the fixed block 315 is provided with fixed grooves 314 at the top and bottom, and a limiting rod 313 is arranged in the fixing groove 314, and a support spring 312 is sleeved on the outer side of the limiting rod 313, and a limiting clamping block 311 is abutted on the upper end of the support spring 312, and a limiting groove 310 is provided on the limiting clamping block 311, and the limiting rod 313 is slidably arranged in the limiting groove 310.

[0036] As an optimization scheme of the utility model, by providing a self-locking device 31, automatic locking can be achieved to lock the protective door 2 firmly; by providing a holding device 34, a reverse force is applied to the locking device 3, so that the locking device 3 can close the two protective doors 2 more tightly.

[0037] When in use, firstly, the mounting frame 1 is attached to the body of the circular knitting machine, and then the bolt 13 inside the mounting hole 12 is passed through the mounting hole 12, and finally the device is threadedly connected to the body of the circular knitting machine, so that the device is installed on the surface of the body of the circular knitting machine to protect the body of the circular knitting machine.

[0038] The working principle of the locking device 3 is as follows: the latch rod 32 is inserted into the locking block 30. During this process, the inclined surface of the limit block 311 is squeezed, that is, the limit block 311 is pushed into the installation groove 33. At this time, the support spring 312 is compressed until the limit block 311 passes through the locking block 30, the support spring 312 rebounds and pushes the limit block 311 to rebound and reset, and the end plate of the limit rod 313 is blocked by the limit groove 310. The pop-up limit block 311 limits the latch rod 32 to prevent the latch rod 32 from falling off. Then the holding spring 341 on the top plate at the other end of the latch rod 32 will clamp the block 342 against the locking block 30 on the left side, forming an opposite effect, which will make the fixation more secure.
