[0029] The technical scheme of the utility model is further illustrated below in combination with the drawings and through specific embodiments.

[0030] As Figure 1 shown, the embodiment provides a sheath protection sleeve, which comprises a protection sleeve body 100 and an end cap 200, the protection sleeve body 100 is provided with an accommodating groove 110 penetrating along the axial direction thereof for passing the sheath, the accommodating groove 110 is used for accommodating the sheath, the protection sleeve body 100 is provided with a mounting port 120 penetrating along the axial direction, and the mounting port 120 is communicated with the accommodating groove 110; the protection sleeve body 100 can be elastically deformed to bend along the axial direction and restore the elastic deformation.

[0031] By providing the accommodating groove 110 in the protection sleeve body 100, the sheath is accommodated; specifically, the protection sleeve body 100 is further provided with the mounting port 120 penetrating along the axial direction thereof, and the mounting port 120 is communicated with the accommodating groove 110; by providing the mounting port 120, the sheath can enter the accommodating groove 110 from the mounting port 120, and compared with threading, the mounting mode of the mounting port 120 is more convenient, and the mounting process is irrelevant to whether other devices are arranged at the end of the sheath, and more use scenarios can be adapted without destructive disassembly. When the sheath protection sleeve is arranged outside the sheath, the protection sleeve body 100 can be elastically deformed to bend along the axial direction and restore the elastic deformation, thereby effectively protecting the sheath at the connection position and avoiding damage caused by excessive bending of the sheath.

[0032] It is worth noting that the elastic performance of the protection sleeve body 100 can also expand the mounting port 120 to install and dismount the sheath. Exemplarily, the cross section of the accommodating groove 110 is circular to adapt to the sheath with a circular cross section; at this time, the width of the mounting port 120 is smaller than the diameter of the accommodating groove 110. Further, the width of the mounting port 120 is smaller than the outer diameter of the sheath, so that the sheath can be prevented from coming out of the protection sleeve body 100.

[0033] Specifically, the protection sleeve body 100 is provided with a groove 130, the extension direction of the groove 130 is arranged at an angle with the axial direction of the protection sleeve body 100, when the protection sleeve body 100 is deformed and bent, the width of the groove 130 also changes correspondingly, thereby improving the deformation capacity of the protection sleeve body 100. Exemplarily, the extension direction of the groove 130 is perpendicular to the axial direction of the protection sleeve body 100.

[0034] Further, the plurality of grooves 130 are evenly spaced along the axial direction of the protective sleeve body 100, which is conducive to improving the bending deformation capability of the protective sleeve body 100, and the uniform arrangement is conducive to ensuring that the bending trajectory of the protective sleeve body 100 to the armored cable inside is consistent. In addition, the protective sleeve body 100 is provided with grooves 130 in the axial direction, that is, the protective sleeve body 100 can be bent along the length direction, and the longer bendable length can effectively reduce the bending angle, thereby improving the protection effect on the armored cable.

[0035] In the embodiment, one end of the groove 130 is communicated with the mounting port 120, which further improves the increase of the bending performance of the groove 130 to the protective sleeve body 100. Preferably, different ends of adjacent grooves 130 are communicated with the mounting port 120, which is arranged so that the circumferential stress of the protective sleeve body 100 is more uniform, avoiding that the protective sleeve body 100 can only be bent towards one side, thereby making the bending effect of the protective sleeve body 100 along the circumferential direction more consistent, and the protection effect on the armored cable placed inside is better. Exemplarily, the end of the groove 130 away from the communicated end of the mounting port 120 is arranged as a semicircle, which is conducive to reducing stress concentration.

[0036] Specifically, the protective sleeve body 100 is provided with a fillet 140 at the connection position of the groove 130 and the mounting port 120, which avoids scratching the armored cable inside when the protective sleeve body 100 is bent.

[0037] It is worth noting that the width of the plurality of grooves 130 accounts for 0.3-0.7 of the axial length of the protective sleeve body 100, and the width of the groove 130 accounts for too small, which is not conducive to improving the bending performance of the protective sleeve body 100, and the width of the groove 130 accounts for too large, which will reduce the structural strength of the protective sleeve body 100. Exemplarily, the spacing between adjacent grooves 130 is substantially the same as the width of the groove 130, that is, the width of the plurality of grooves 130 accounts for 0.5 of the axial length of the protective sleeve body 100.

[0038] In other embodiments, the end of the groove 130 can also be arranged not to be communicated with the mounting port 120. Exemplarily, the groove 130 is arranged in a snake shape on the protective sleeve body 100, and those skilled in the art can arrange the specific form of the groove 130 according to the needs, which is not limited here.

[0039] Further, the end cap 200 is arranged at one end of the protective sleeve body 100 in the axial direction, the outer diameter of the end cap 200 is larger than the outer diameter of the protective sleeve body 100, and the accommodating groove 110 and the mounting port 120 are both penetrated through the end cap 200. By arranging the end cap 200 with an outer diameter larger than the outer diameter of the protective sleeve body 100, the positioning and installation of the armored cable protection sleeve as a whole are realized.

[0040] Preferably, the protective sleeve body 100 and the end cap 200 are integrally arranged, that is, the armored protective sleeve is integrally arranged, and the connection is more reliable.

[0041] As shown in Figure 2 The embodiment also discloses a handheld laser welding gun provided with the armored protective sleeve according to any one of the above solutions, and the handheld welding gun comprises a welding gun shell 1, and the armored protective sleeve is arranged at the tail of the welding gun shell 1. Specifically, the inside of the welding gun shell 1 can be provided with a clamping groove matched with the end cap 200, so as to realize the positioning and installation between the welding gun shell 1 and the armored protective sleeve.

[0042] The embodiment also discloses a laser processing equipment provided with the armored protective sleeve according to any one of the above solutions, and the armored protective sleeve can effectively protect the armored cable, and the safety in use is higher.

[0043] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific embodiment and application range can be changed, and the content of the specification should not be understood as a limitation of the present application.
