Description

Technical Field

[0001] The utility model relates to the field of wire drawing machines, in particular to a locking structure for a protective cover of a wire drawing machine. Background Art

[0002] Straight-type wire drawing machine is one of the common metal wire processing equipment. Straight-type wire drawing machine can perform wire drawing processing on high, medium and low carbon steel wire, stainless steel wire, copper wire, alloy copper wire, aluminum alloy wire, etc.

[0003] A Chinese utility model patent discloses a safety locking device for a wire drawing machine protective cover, with the authorization announcement number CN214556323U. The structure of the device is described as comprising a wire drawing machine housing and a protective cover mounted on the wire drawing machine housing, wherein one end of the protective cover is hinged to the wire drawing machine housing, and the other end is fixedly connected to the wire drawing machine housing via an electronic lock. A cylinder is fixedly mounted on the wire drawing machine housing, and the piston rod of the cylinder is connected to the moving rod. The moving rod has a working position and a non-working position on the path where the moving rod is driven by the cylinder to move. The device also comprises a sensor for detecting whether the moving rod is in the working position, and the sensor is electrically connected to the wire drawing machine power supply. The working position of the moving rod is detected by the sensor. If the device is detected to be in the working position, that is, the moving rod is not detected, and the cylinder has no signal transmitted to the wire drawing machine power supply, the device can be started and operated. On the contrary, if the sensor does not detect the moving rod, the cylinder transmits a signal to the wire drawing machine power supply, and the wire drawing machine cannot be started and cannot be turned on, which can effectively prevent potential safety accidents.

[0004] The drawback of the patented wire drawing machine protective cover safety locking device is that the wire drawing machine housing is lifted by a cylinder, which transmits a signal to the wire drawing machine power supply. The wire drawing machine can only start normally after the housing is properly closed. When this structure is used in actual field equipment, when the wire drawing machine housing encounters iron filings, it cannot be closed tightly, causing the wire drawing machine to be unable to start normally, seriously affecting the normal use of the equipment and affecting the production efficiency of the equipment.

[0019] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0020] like Figure 1-4 As shown, the utility model is a locking structure for a wire drawing machine protective cover, comprising: a hook-shaped clip 7, and a special-shaped clip 8 that is opened and closed and locked with the hook-shaped clip 7; the special-shaped clip 8 is rotatably connected to the U-shaped connecting member 10 through a torsion spring 14, and a handle 6 is also connected to the special-shaped clip 8.

[0021] The wire drawing machine protective cover of this embodiment is provided with an openable and closable protective door, which can be opened by horizontal displacement or opened and closed up and down; the hook-shaped clamp 7 is installed on the protective cover, and the special-shaped clamp 8 is installed on the protective door.

[0022] Specifically, the U-shaped connector 10 is connected to the open and closed protective door. A positioning spindle 13 is provided on the U-shaped connector 10. The special-shaped clip 8 is sleeved on the outside of the positioning spindle 13. A torsion spring 14 is provided between the special-shaped clip 8 and the U-shaped connector 10. A knob 9 is connected to the outside of the special-shaped clip 8, and the handle 6 passes through the protective door and is connected to the knob 9.

[0023] In this embodiment, the tension of the torsion spring 14 is relatively small, and the two end legs of the torsion spring 14 are fixedly connected to the special-shaped clamp 8 and the U-shaped connector 10 respectively. When the special-shaped clamp 8 does not need to move and is in a parallel state, the torsion spring 14 is in a conventional unstressed state; when the special-shaped clamp 8 rotates upward, the torsion spring 14 provides a downward pulling force.

[0024] Specifically, when the special-shaped clip 8 conflicts with the outer surface of the hook-shaped clip 7, the special-shaped clip 8 rotates upward along the outer slope of the hook-shaped clip 7. When the special-shaped clip 8 moves to the end of the hook-shaped clip 7, the special-shaped clip 8 is restored by the force of the torsion spring 14, thereby being hooked and locked with the end of the hook-shaped clip 7; when the handle 6 is twisted, the special-shaped clip 8 is driven to rotate through the knob 9, separating it from the hook-shaped clip 7, thereby opening the protective door.

[0025] Furthermore, the hook-shaped clip 7 is connected to the connecting assembly, which includes: an upper positioning plate 1 connected to the protective cover, a supporting bottom plate 2 connected to the upper positioning plate 1, and a supporting block 3 connected to the supporting bottom plate 2; the hook-shaped clip 7 is connected to the lower side of the support block 3 through the bottom connecting plate 5 and the connecting member 4.

[0026] In this embodiment, the upper positioning piece 1, the supporting bottom piece 2, the bottom connecting piece 5, the hook-shaped clamp 7, the special-shaped clamp 8, the U-shaped connecting piece 10, and the positioning ring piece 12 are made of stainless steel or galvanized iron plate stamping parts.

[0027] Furthermore, a positioning ring 12 is connected to the positioning spindle 13 , and a bearing pulley 11 is connected to the positioning ring 12 .

[0028] Working principle: When the special-shaped clip 8 conflicts with the outer side of the hook-shaped clip 7, the special-shaped clip 8 rotates upward along the outer slope of the hook-shaped clip 7. When the special-shaped clip 8 moves to the end of the hook-shaped clip 7, the special-shaped clip 8 is restored by the force of the torsion spring 14, thereby being hooked and locked with the end of the hook-shaped clip 7; when the handle 6 is twisted, the special-shaped clip 8 is driven to rotate through the knob 9, separating it from the hook-shaped clip 7, thereby opening the protective door.
