[0024] A wire harness protection device, referring to Figures 1 - 4 , includes an upper housing 1 and a lower housing 2. The upper housing 1 is recessed inward to form a winding groove 3. A through mounting hole 4 is provided at the bottom of the winding groove 3. A plurality of card slots are provided around the mounting hole 4 at the bottom of the winding groove 3. A positioning post 5 is provided on the lower housing 2. Elastic mounting ears 6 corresponding to the card slots are provided around the circumference of the positioning post 5. An insertion strip 7 is provided on the lower housing 2. A slot for the insertion strip 7 to be inserted is provided on the upper housing 1. After the insertion strip 7 of the lower housing 2 is inserted into the slot, one end of the positioning post 5 passes through the mounting hole 4 while the elastic mounting ear 6 is clamped in the card slot.

[0025] Further, the card slot includes a notch 81 provided at the bottom of the winding groove 3. A clamping block 82 corresponding to the notch 81 is provided on the side wall of the winding groove 3. One end of the elastic mounting ear 6 passes through the notch 81 and its upper end abuts against the clamping block 82.

[0026] Further, the insertion strip 7 is arranged along the length direction of the lower housing 2.

[0027] Further, a first connecting member 11 and a second connecting member 12 are spaced apart on the upper housing 1, and the first connecting member 11, the second connecting member 12, and the upper housing 1 surround to form the slot.

[0028] Further, two winding grooves 3 are provided at intervals along the length direction of the upper housing 1, and a visible window 9 corresponding to the winding groove 3 is provided on the circumferential side of each upper housing 1.

[0029] The working principle of the present utility model is:

[0030] As Figure 4 shown, as Embodiment 1, this application takes the example of having two winding grooves 3 provided on the upper housing 1, with eight mounting ears provided on the lower housing 2, and four card slots are opened at the bottom of each winding groove 3. When the upper housing 1 is mounted on the lower housing 2, one end of the positioning post 5 passes through the mounting hole 4, and each elastic mounting ear 6 is snap - connected to the corresponding card slot. At the same time, the insert bar 7 on the lower housing 2 is inserted into the slot on the upper housing 1. With this design, the installation between the upper housing 1 and the lower housing 2 can be achieved, and the wire harness can be wound around the outer surface of the winding groove 3 (that is, the wire harness is located in the space surrounded by the upper housing 1 and the lower housing 2, as shown by the wire harness 1 - 1 in Figure 2 ), or wound into a roll and placed on the bottom of the winding groove 3. That is to say, when two winding grooves 3 are opened, four rolls of wire harnesses can be stored simultaneously. The wire harnesses placed in the winding groove 3 are convenient for the operator to access, and the wire harnesses wound around the outer surface of the winding groove 3 can be used to store the idle wire harnesses. When it is necessary to access the wire harness wound around the outer surface of the winding groove 3, at this time, only the connection between the mounting ear and the card slot needs to be released, and then the upper housing 1 is moved upward. At the same time as the positioning post 5 on the lower housing 2 disengages from the mounting hole 4, the insert bar 7 on the lower housing 2 also disengages from the slot on the upper housing 1. With this design, the upper housing 1 and the lower housing 2 can be easily disconnected, and then the wire harness wound around the outer surface of the winding groove 3 of the upper housing 1 can be removed and placed in the storage groove, and finally the upper housing 1 is mounted on the lower housing 2.

[0031] In the above - mentioned technical solution, in order to enable the user to quickly identify the model of the wire harness to be used, this application provides a visible window 9 on the upper housing 1. Through the visible window 9, the model or color of the wire harness wound around the outer surface of the winding groove 3 can be quickly seen, so that the corresponding wire harness can be quickly found.

[0032] On the basis of the above - mentioned technology, regarding the connection method between the card slot and the elastic mounting ear 6, as Embodiment 1, four notches 81 can be circumferentially provided around the bottom of each storage groove, and a clamping block 82 is provided on the side wall of each storage groove at the position corresponding to the notch 81. When one end of the elastic mounting ear 6 passes through the notch 81, the upper end of the elastic mounting ear 6 abuts against the clamping block 82, thereby realizing the detachable connection between the card slot and the elastic mounting ear 6.

[0033] As Embodiment 1, regarding the plug-in fit between the plug 7 and the slot of the present application, the plug 7 can be arranged along the length direction of the lower housing 2. The first connecting member 11 and the second connecting member 12 are spaced apart at the lower end of the upper housing 1. That is to say, the first connecting member 11, the second connecting member 12, and the upper housing 1 enclose to form a slot. Then, one end of the plug 7 is inserted into the position between the first connecting member 11 and the second connecting member 12 to achieve the plug-in fit.

[0034] On the basis that the present application is provided with a card slot and an elastic mounting ear between the upper housing and the lower housing to achieve connection, a plurality of card slots are also arranged around the circumference of the mounting hole, and the connection is achieved through a plurality of snap fits; in addition, the present application is provided with a slot on the upper housing and a plug on the lower housing, and the plug-in fit between the plug and the slot further enhances the connection strength between the upper housing and the lower housing. At the same time, the present application is also provided with a plurality of winding grooves at intervals on the box body, which can accommodate a plurality of wound wire harnesses at the same time to prevent the wire harnesses from being entangled with each other, and further protects the service performance of the wire harnesses.

[0035] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present invention without departing from the principle and spirit scope defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention, but the scope of protection is defined by the content of the claims.
