Description

Technical Field

[0001] The present application relates to the technical field of extruders, and in particular to an anti-slip extruder head outer cover. Background Art

[0002] During cable production, an extruder is required to cast an insulating layer on the cable surface to ensure the insulation of the cable.

[0003] When pouring the insulation layer on the surface of the extruder, the cable is passed through the extruder head of the extruder. The extruder pours the melted insulation layer material into the extruder head, so that the insulation layer material flows out of the extruder with the cable. The insulation layer material cools and wraps around the outside of the cable, thereby completing the pouring of the insulation layer of the cable.

[0004] The above-mentioned prior art solutions have the following defects: the existing extruder head outer covers are mostly connected to the extruder threads for easy replacement, and the outer surfaces of the existing extruder head outer covers are mostly smooth. When installing and disassembling the extruder head, the installation or disassembly tools will slip, making the installation and disassembly of the extruder head outer cover time-consuming, labor-intensive and very inconvenient. Utility Model Content

[0005] In order to make the disassembly and installation of the extruder head outer cover more labor-saving, the present application provides an anti-skid extruder head outer cover.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] An anti-skid extruder head outer cover comprises an outer cover body, wherein the outer surface of the outer cover body is provided with a plurality of circular welding spots, and a handle bar is provided on the outer cover surface. The handle bars are provided in a plurality and are arranged in a circular array on the outer circumferential surface of the outer cover body.

[0008] By adopting the above scheme, the circular welding points make the surface of the outer shell body rough, so that the pliers-type tool is less likely to slip when removing or installing the outer shell body. When the pliers-type tool is used to loosely connect the outer shell body to the extruder body, the rotation of the outer cover body can be accelerated by manually turning the handle, so that the installation and disassembly of the outer cover body is more time-saving and labor-saving, and the disassembly and installation of the outer cover of the extruder head is more labor-saving.

[0009] Optionally, a groove is provided on the outer circumferential surface of the outer cover body, the handle bar is hinged in the groove, and the handle bar can be completely placed in the groove.

[0010] By adopting the above technical solution, when the outer cover body does not need to be disassembled or installed, the handle can be placed in the groove, thereby reducing the space occupied by the outer cover body and avoiding the outer cover body from affecting other parts and installation and use.

[0011] Optionally, the outer cover body is slidably connected to a sliding sleeve on the side facing away from the extruder, and a plurality of slots are provided on the sliding sleeve close to the outer cover body. An insert rod is fixedly connected to one end of the handle bar facing away from the hinge, and a spring groove is provided in the groove. A spring is connected in the spring groove, and the other end of the spring is fixedly connected to the handle bar. When the handle bar is completely located in the groove, the spring is in a compressed state.

[0012] By adopting the above technical solution, when the handle bar needs to be used, it is only necessary to move the sliding sleeve away from the outer cover body so that the insertion rod slides into the slot, and then the spring rebounds to pop the handle bar out of the groove, and then the operator can operate the handle bar. When the handle bar needs to be retracted, it is only necessary to press the handle bar into the groove, and then move the sliding sleeve toward the outer cover body to insert the insertion rod into the slot, thereby fixing the handle bar in the groove.

[0013] Optionally, a sliding groove is provided on a side of the outer cover body close to the sliding sleeve, a sliding rod is fixedly connected to a side of the sliding sleeve close to the outer cover body, and the sliding rod is slidably connected in the sliding groove.

[0014] By adopting the above technical solution, the sliding rod moves in the sliding groove to limit the moving direction of the sliding sleeve, so that the sliding sleeve can only move in the direction close to or away from the outer cover body. At the same time, the sliding rod moves in the sliding groove to provide a connection point between the sliding sleeve and the outer cover body.

[0015] Optionally, a limit plate is provided at the notch of the slide groove, and a limit block is fixedly connected to the side of the slide rod away from the slide sleeve.

[0016] By adopting the above technical solution, the limiting plate and the limiting block limit the slide bar from sliding out of the slide groove, thereby preventing the slide sleeve from separating from the outer cover and preventing the slide cover from being easily damaged or lost.

[0017] Optionally, a card slot is opened in the slide groove, an elastic member is arranged in the card slot, a card block is connected to the end of the elastic member, the card block part is located in the card slot, and the card block part is located in the slide groove. When the limit block contacts the card block, the limit block squeezes the card block into the card slot.

[0018] By adopting the above technical solution, when the slide rod slides into the slide groove, the limit block contacts the clamping block, and the limit block presses the clamping block completely into the clamping groove, causing the elastic member to deform. When the limit block passes the clamping block, the elastic member rebounds so that the clamping block clamps the limit block. At this time, the slide rod slides to the deepest part of the slide groove, and the clamping block can limit the movement of the slide sleeve when the handle is not needed. When the slide rod needs to be used, the operator can pull the slide sleeve slightly to make the slide sleeve move away from the outer cover body.

[0019] Optionally, the card block is a card block in the shape of a triangular prism.

[0020] By adopting the above technical solution, the spherical card block can make it easier for the card block to fully enter the card slot when the limit block contacts the card block, and the spherical card block can reduce the wear of the card block and the limit block, thereby extending the service life of the outer cover.

[0021] Optionally, friction patterns are arranged on the outer side of the sliding sleeve.

[0022] By adopting the above technical solution, the occurrence of slipping is reduced when the operator slides the sliding sleeve, so that the operator can slide the sliding sleeve more easily.

[0023] In summary, this application has the following technical effects:

[0024] 1. The installation and removal of the outer cover body are made easier by setting circular welding points and handles;

[0025] 2. By providing a groove and hingedly connecting the handle and the outer cover body, the handle can be placed in the groove to reduce the volume of the outer cover;

[0026] 3. The limit plate and the limit block are provided to prevent the sliding sleeve and the outer cover body from being separated. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] Reference Figure 1 and Figure 2, an anti-skid extruder head outer cover, characterized in that: it includes an outer cover body 1, the inner circumferential surface of the outer cover body 1 is provided with threads, and the outer cover body 1 is threadedly connected to the extruder body 4, a plurality of circular welding points 13 are provided on the outer circumferential surface of the outer cover body 1, and a plurality of handles 2 are provided on the outer circumferential surface of the outer cover body 1, and the plurality of handles 2 are distributed in a circle. When it is necessary to install the outer cover body 1, the handle 2 can be manually operated to thread the outer cover body 1 with the foundation and the body, and then the pliers-type tool can be used to tighten and fix the outer cover body 1 and the extruder body 4. The circular welding points 13 make it difficult for the pliers-type tool to slip when reinforcing the outer cover body 1, increase the friction between the pliers-type tool and the outer cover body 1, not only making the installation of the outer cover body 1 easier, but also making the connection between the outer cover body 1 and the extruder body 4 more secure.

[0035] Reference Figure 1 and Figure 2 A groove 12 in the axial direction of the outer cover body 1 is provided on the outer circumferential surface of the outer cover body 1, and the handle 2 is hinged in the groove 12, and the handle 2 can completely enter the groove 12. After the outer cover is installed or removed, the handle 2 can be placed in the groove 12 to make the outer cover body 1 occupy less space, avoiding interference with the installation and use of other parts on the extruder body 4.

[0036] Reference Figure 2 and Figure 5 An inner slot 311 connected to the plurality of grooves 12 is provided on the side of the outer cover body 1 away from the extruder body 4, the inner slot 11 is connected to the sliding sleeve 3, the sliding sleeve 3 includes a collar 31 and a side ring 32, the collar 31 is sleeved on the outside of the inner slot 11, and the collar 31 is slidably connected to the inner slot 11, the side ring 32 is fixedly connected to the collar 31, the side ring 32 is located on the side of the outer cover body 1 away from the extruder body 4, and a plurality of slots 311 are provided on the side of the collar 31 away from the side ring 32, and the number of the slots 311 is the same as that of the inner slot 11. The number of grooves 12 is the same, and the slot 311 is opposite to the groove 12. The rod 21 is fixedly connected to the end of the handle 2 away from the hinge. When the rod 21 is completely located in the groove 12, the rod 21 can be inserted into the slot 311. A spring slot 121 is provided in the groove 12, and a spring 22 is provided in the spring slot 121. One end of the spring 22 is fixedly connected to the bottom end of the spring slot 121, and the other end of the spring 22 is fixedly connected to the handle 2. When the handle 2 is completely located in the groove 12, the spring 22 is in a compressed state. When it is necessary to install or disassemble the outer cover body 1, the sliding sleeve 3 can be slid away from the outer cover body 1, so that the rod 21 slides out of the slot 311, and then the spring 22 rebounds to lift the handle 2, so that the handle 2 pops out of the groove 12, so that the operator can operate the handle 2 to drive the outer cover body 1 to be screwed in or out of the extruder body 4.

[0037] Reference Figures 2 to 5A friction pattern is provided on the outer circumferential surface of the sleeve ring 31, so that the operator can slide the sleeve 3 more easily. A plurality of slide grooves 14 are provided on the side of the outer cover body 1 away from the extruder body 4. A plurality of slide rods 321 are provided at the side ring 32 facing the slide groove 14. The slide rod 321 is slidably connected in the slide groove 14. A limit plate 141 for limiting the slide rod 321 from sliding out of the slide groove 14 is provided at the notch of the slide groove 14. A limit block 322 is fixedly connected to the side of the slide rod 321 away from the side ring 32. When the slide rod 321 is about to slide out of the slide groove 14, the limit plate 141 clamps the limit block 322, thereby preventing the slide rod 321 from continuing to slide out, thereby preventing the outer cover body 1 from being separated from the sleeve 3, causing the sleeve 3 to be easily lost or damaged. A slot 15 is provided in the chute 14, and the slot 15 is arranged near the bottom of the chute 14. An elastic member 151 is fixedly arranged in the slot 15, and the elastic member 151 is connected with a block 152 in the shape of a triangular prism, and a part of the block 152 is located in the slot 15, and another part of the block 152 is located in the chute 14. When the slide bar 321 slides toward the bottom of the chute 14, the limit block 322 contacts the block 152, and the limit block 322 completely presses the block 152 into the slot 15, so that the elastic member 151 is deformed, and then the limit block 322 passes through the block 152, and the elastic member 151 rebounds so that the block 152 clamps the limit block 322 in the chute 14, thereby preventing the sliding sleeve 3 from sliding out and the handle 2 from bouncing up when the extruder is working. When the sliding sleeve 3 needs to be slid, the operator only needs to apply a little force to make the limit block 322 slide in the chute 14.

[0038] The specific implementation principle of the present application is as follows: when the outer cover body 1 needs to be installed, the outer cover body 1 is first placed at the desired installation location, and then the sleeve 3 is slid away from the outer shell body, so that the insertion rod 21 slides out of the slot 311, and the spring 22 rebounds to pop the handle 2 out of the groove 12. The operator drives the outer cover body 1 to be threadedly connected with the extruder body 4 through the handle 2, and then presses the handle 2 into the groove 12, and slides the sleeve 3 toward the outer cover body 1, so that the insertion rod 21 is inserted into the slot 311, thereby fixing the handle 2 in the groove 12. Then, the operator can also use a pliers tool to make the connection between the outer cover body 1 and the extruder body 4 more tightly, and the circular welding point 13 can increase the friction between the pliers tool and the outer cover body 1, so that the outer cover body 1 can be fixed more tightly. Compared with the existing extruder head outer cover, the extruder head outer cover makes it easier and more convenient for operators to remove and install the outer cover body 1.
