Description

Technical Field

[0001] The present application relates to the technical field of steel bar processing, and in particular to a steel bar thread head marking device. Background Art

[0002] Rebar is the main consumable material in the construction process, and the steel cage assembled from it has become the main support in most building structures. At present, the most widely used technology in construction is the straight threaded steel bar connection technology, which mainly makes threaded heads at the ends of the two steel bars that need to be connected, and then uses sleeves to fix the threaded heads of the two steel bars to achieve the purpose of connection. First, it is necessary to indicate the specified length on the long steel bar thread head and the short steel bar thread head, and then screw the sleeve into the long wire end, and then connect the short wire steel bar to the long wire steel bar end, and finally use a tool to screw the sleeve back onto the short wire steel bar, so that the sleeve is located in the middle of the root steel bar mark to control the precise and stable connection positioning of the threaded sleeve.

[0003] In the prior art, when drawing lines or marking on steel wire heads, the steel wire heads are generally measured manually with a ruler, and then lines are drawn on the steel wire heads using ink to make corresponding marks. This method of measuring with a ruler and then marking is relatively inefficient, and therefore needs further improvement. Utility Model Content

[0004] In order to speed up the efficiency of marking lines on steel wire heads, the present application provides a steel wire head marking device.

[0005] This application provides a steel wire head marking device, which adopts the following technical solutions:

[0006] A device for marking a steel wire head includes a sleeve and a marking piece arranged on the sleeve. The sleeve has a cavity inside. One end surface of the sleeve is provided with a slot connected to the cavity for the steel wire head to be slidably inserted. The outer peripheral wall of the sleeve is provided with a through groove connected to the cavity along its radial direction. The marking piece is used to be inserted into the through hole to mark the steel wire head.

[0007] By adopting the above technical solution, the steel wire head is passed through the sleeve to initially position the steel wire head, and the provided drawing piece is used to draw lines on the steel wire head after passing through the groove. Since the position of the groove is relatively fixed on the sleeve, the time spent on measuring a certain length can be reduced, thereby speeding up the efficiency of drawing lines on the steel wire head and reducing the possibility of errors due to measurement.

[0008] Preferably, a first connecting piece is provided on the sleeve, and the line drawing piece is detachably connected to the sleeve via the first connecting piece.

[0009] By adopting the above technical solution, the line drawing piece can be installed on the sleeve by providing a first connecting piece, which is relatively convenient to use. As the line drawing piece is used up, the first connecting piece is provided to facilitate the disassembly and replacement of the line drawing piece, or to replace the slotted sleeve at different heights, so as to adapt to the steel wire heads that require different lengths of line drawing according to needs.

[0010] Preferably, the line drawing member is a paint spray can, and the nozzle of the paint spray can is aligned with the through groove.

[0011] By adopting the above technical solution, by pressing the nozzle of the spray paint can, the paint in the can body is sprayed through the groove and sprayed onto the steel wire head. Compared with when a paintbrush passes through the groove to draw lines, the paint has a higher degree of coloration under pressure and is relatively fast, thereby further accelerating the efficiency of drawing lines on the steel wire head.

[0012] Preferably, the first connecting member is a snap-on tie wrapped around the paint spray can, and the outer peripheral wall of the sleeve is provided with two through-holes for respectively passing the two ends of the snap-on tie.

[0013] By adopting the above technical solution, since the body of the spray paint can is usually circular, it is relatively easy to install the spray paint can on the sleeve for fixation through the hook and loop cable tie, and since it is a hook and loop cable tie, it is convenient to replace the spray paint can.

[0014] Preferably, an elastic pad is provided on the inner peripheral wall of the snap tie, and anti-slip grooves are provided on the elastic pad.

[0015] By adopting the above technical solution, an elastic pad and anti-slip grooves are provided to enhance the friction between the spray can and the paint can, thereby improving the fixing effect of the spray can and reducing the possibility of relative slippage between the nozzle and the groove when pressing the nozzle to spray.

[0016] Preferably, an adsorption layer is attached to the sleeve near the through groove, and the adsorption layer is used to adsorb paint.

[0017] By adopting the above technical solution, during actual use of the spray paint can, some paint will be sprayed near the groove. In this regard, an adsorption layer is provided to adsorb the paint sprayed near the groove, thereby reducing the difficulty of cleaning the paint sprayed onto the sleeve.

[0018] Preferably, the outer peripheral wall of the sleeve is slidingly connected to the first adjustment plate, the through groove is arranged on the first adjustment plate, the outer peripheral wall of the sleeve is provided with a connecting groove connected to the through groove and the cavity, the connecting groove extends to the end face of the sleeve located in the slot, the sleeve is provided with a limit piece for the sliding of the first adjustment plate, and the sleeve is provided with scale lines along its height direction.

[0019] By adopting the above technical solution, a first adjustment plate is provided, which slides to the corresponding height position marked on the scale line, and is limited by a limiter to fix the height position of the through-groove at this time. The height position of the through-groove can be adjusted, thereby reducing the cost of configuring sleeves with through-grooves at different height positions.

[0020] Preferably, the inner diameter of the sleeve is larger than the diameter of the steel wire head, and the sleeve is detachably connected to a second adjustment plate at the slot, and the two opposite surfaces of the second adjustment plate respectively abut against the inner circumferential wall of the sleeve and the steel wire head.

[0021] By adopting the above technical solution, the inner diameter of the sleeve is usually larger than the diameter of the steel wire head, and a second adjustment plate is detachably connected to it so as to adapt to steel wire heads of different diameters and pass through slots to abut against the bottom inner wall of the sleeve for fixation. By configuring second adjustment plates of different thicknesses, the cost is relatively reduced compared to configuring a sleeve with a same inner diameter.

[0022] Preferably, the upper end surface of the second adjustment plate is fixedly connected to a connecting plate, and the connecting plate is connected to an abutting plate abutting against the outer peripheral wall of the sleeve, and the connecting plate and the abutting plate are both made of elastic rubber.

[0023] By adopting the above technical solution, the connecting plate and the abutting bar are both made of elastic rubber. The elasticity of the rubber itself makes it easy to install the second abutting plate on the sleeve and also facilitate disassembly.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. Pass the steel wire head through the sleeve to initially position the steel wire head, and the provided drawing piece is used to draw the steel wire head after passing through the groove. Since the position of the groove is relatively fixed on the sleeve, the time spent on measuring a certain length can be reduced, thereby speeding up the drawing efficiency of the steel wire head and reducing the possibility of errors due to measurement.

[0026] 2. By providing a first adjustment plate, sliding it to the corresponding height position marked on the scale line, and limiting it through a limiter, the height position of the through-groove at this time is fixed, and the height position of the through-groove can be adjusted, thereby reducing the cost of configuring sleeves with through-grooves at different heights.

[0027] 3. A second adjustment plate is provided to adapt to different diameters of steel wire heads passing through the slots to abut against the bottom inner wall of the sleeve for fixation. By configuring second adjustment plates of different thicknesses, the cost is relatively reduced compared to configuring sleeves with the same inner diameter. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-4 , further details of this application are given.

[0034] The embodiment of the present application discloses a device for marking lines on steel wire heads.

[0035] Example 1:

[0036] A steel wire head drawing device, referring to Figure 1 , including a sleeve 1 and a marking piece 2 arranged on the sleeve 1. In this embodiment, the sleeve 1 has a cavity 11, and one end surface of the sleeve 1 is provided with a slot 12 connected to the cavity 11 for the sliding insertion of the steel wire head, and the outer peripheral wall of the sleeve 1 is provided with a through groove 3 connected to the cavity 11 along its radial direction.

[0037] The line drawing member 2 is used to be inserted into the perforation 14 to mark the end of the steel wire. In this embodiment, the line drawing member 2 is specifically a spray paint can, and the nozzle of the spray paint can is aligned with the perforation groove 3. The sleeve 1 is provided with a first connecting member 13, and the line drawing member 2 is detachably connected to the sleeve 1 through the first connecting member 13. In this embodiment, the first connecting member 13 is a slip-on cable tie. The outer peripheral wall of the sleeve 1 is provided with two perforations 14 for respectively passing the two ends of the slip-on cable tie.

[0038] The working principle of the wire marking device of the embodiment of the present application is as follows: the wire is passed through the sleeve 1 to initially position the wire, and the nozzle of the spray can is pressed to spray the paint in the can through the slot 3 onto the wire. The paint has a high degree of coloration under the pressure spray and is sprayed relatively quickly, thereby further accelerating the efficiency of marking the wire. With use, the paint in the spray can will be exhausted, so a first connecting member 13 is provided to facilitate the removal and replacement of the marking member 2.

[0039] Example 2:

[0040] Reference Figure 2 The difference from Example 1 is that the inner wall of the slip-on cable tie is provided with an elastic pad 4 with anti-slip grooves (not shown). Furthermore, an adsorption layer 5 is attached to the sleeve 1 near the through groove 3. The adsorption layer 5 is used to absorb paint. The adsorption layer 5 can be a sponge and can be fixed to the sleeve 1 with double-sided tape so that it can be replaced when the adsorption reaches a certain level.

[0041] Example 3:

[0042] Reference Figure 3 、 Figure 4 The difference from Example 1 is that the outer peripheral wall of the sleeve 1 is slidably connected to the first adjustment plate 6, the through-slot 3 is provided in the first adjustment plate 6, and the outer peripheral wall of the sleeve 1 is provided with a connecting groove 15 that connects the through-slot 3 and the cavity 11. The connecting groove 15 extends to the end face of the sleeve 1 located in the slot 12. The sleeve 1 is provided with a limiter 61 to limit the sliding of the first adjustment plate 6. In this embodiment, the limiter 61 is specifically a slip-on tie, which is fixedly connected to the first adjustment plate 6 and wrapped around the outer peripheral wall of the sleeve 1. The sleeve 1 is provided with scale lines 16 along its height direction.

[0043] In this embodiment, the inner diameter of the sleeve 1 is larger than the diameter of the steel wire head. The sleeve 1 is detachably connected to a second adjustment plate 7 at the slot 12. The two opposite surfaces of the second adjustment plate 7 abut against the inner peripheral wall of the sleeve 1 and the steel wire head, respectively. The upper end surface of the second adjustment plate 7 is fixedly connected to a connecting plate 71. The connecting plate 71 is connected to an abutting plate 72 that abuts against the outer peripheral wall of the sleeve 1. Both the connecting plate 71 and the abutting plate 72 are made of elastic rubber. It should be noted that the abutting plate 72 can extend to the hook and loop tie to fix it under the binding of the hook and loop tie, thereby reducing the possibility of the second adjustment plate 7 slipping and detaching. At this time, the connecting plate 71 and the abutting plate 72 can be made of plates of other materials such as metal plates, plastic plates or wooden plates.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
