External dust and rainwater can easily enter, causing corrosion, pollution, and aging at the joint position, which greatly affects the normal use of the cable. In addition, the installation and subsequent disassembly of the connecting device for maintenance and relocation are relatively cumbersome, with low operating efficiency, affecting the construction progress.

[0003] Therefore, a quick-assembly cable connection device is needed to solve the above problems. Utility Model Content

[0004] The utility model proposes a quick-assembly cable connection device, which performs a sealing treatment on the cable connection position, thereby improving the protection effect of the cable joint position. At the same time, a quick-assembly structure is adopted between the protective shell and the end sealing component, which improves the installation efficiency of the device and makes subsequent maintenance and disassembly more convenient.

[0005] The technical solution of the present utility model is achieved as follows:

[0006] A quick-assembly cable connection device includes a protective shell that is sleeved on the outside of the cable connection position, and both ends of the protective shell are detachably installed with an end sealing assembly, each of the end sealing assemblies includes a limit sleeve, and one end of each limit sleeve is provided with an annular groove that is compatible with the end of the protective shell, and an annular sealing element is provided between each of the annular grooves and the end of the protective shell, and two limit columns are provided at both ends of the outer wall of the protective shell, and two limit grooves for limiting the corresponding limit columns are symmetrically provided on the side walls of the annular groove, and a supporting end surface is provided between the inner wall of each limit sleeve and the corresponding annular groove, and an installation groove is provided on the inner wall of the protective shell, and a reset element is provided between each of the installation grooves and the corresponding supporting end surface, and the other end of each limit sleeve is provided with an end sealing element that is compatible with the outer circumference of the cable.

[0007] As a preferred technical solution, the protective shell includes a first shell and a second shell that are compatible with each other, the first shell includes a first curved outer plate and a first curved inner plate, a number of first connecting plates are fixedly installed between the first curved outer plate and the first curved inner plate, a first protrusion is respectively provided at both ends of the outer wall of the first curved outer plate, and a second protrusion is respectively provided at both ends of the outer wall of the first curved inner plate, the second shell includes a second curved outer plate and a second curved inner plate, a number of second connecting plates are fixedly installed between the second curved outer plate and the second curved inner plate, two first grooves corresponding to the first protrusions are provided on the outer wall of the second curved outer plate, and two second grooves corresponding to the second protrusions are provided on the inner wall of the second curved inner plate.

[0008] As a preferred technical solution, one mounting groove is fixedly mounted on both ends of the inner walls of the first arc-shaped inner plate and the second arc-shaped inner plate.

[0009] As a preferred technical solution, each of the limit grooves includes an arc-shaped guide groove and a positioning groove, each of the positioning grooves is arranged along the axial direction of the corresponding limit sleeve, one end of each of the arc-shaped guide grooves is connected to the end face of the corresponding limit sleeve, and the other end of each of the arc-shaped guide grooves is connected to the end of the corresponding positioning groove.

[0010] As a preferred technical solution, a limiting column is respectively provided on the outer walls at both ends of the first curved outer plate and the second curved outer plate.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] Since the quick-assembly cable connection device includes a protective shell and an end sealing component, when using this device, a limit sleeve is first put on each cable to be connected, the cable is connected, and then the protective shell is put on the cable connection position, and the limit sleeve at one end is moved toward the direction close to the protective shell. The two limit posts at one end of the protective shell move along the arc-shaped guide groove respectively. As the limit sleeve moves, the two limit posts eventually move into the positioning groove, and the end of the protective shell rests on the annular sealing element. Under the action of the reset element, the limit sleeve is subjected to a force in the direction away from the protective shell, and since the limit post is blocked by the side wall of the positioning groove, the protective shell and The locking of the limit sleeve. In the utility model, the cable connection position is sealed by the protective shell and the limit sleeve. At the same time, the setting of the annular sealing element improves the sealing between the end of the protective shell and the limit sleeve. The setting of the end sealing element improves the sealing between the cable and the end of the limit sleeve, reduces the entry of external dust and rainwater, and causes corrosion, pollution, aging, etc. to the joint position, thereby improving the protection effect of the cable joint position. Through the cooperation of the limit column, the limit groove and the reset element, the rapid assembly between the protective shell and the end sealing component is achieved, the installation efficiency of the device is improved, and the later maintenance and disassembly is also more convenient.

[0013] Since the quick-assembly cable connection device includes a protective shell, during the installation of the protective shell, the connected cable is located on the inner side of the first curved inner plate and the second curved inner plate, and then the first protrusion is moved from one end of the second groove to the second groove, and the second protrusion is moved from one end of the second groove to the second groove, so that the quick assembly of the first shell and the second shell can be completed. In the present utility model, the split setting of the protective shell is realized by the mutual cooperation of the first shell and the second shell, and the quick assembly of the first shell and the second shell is realized by the cooperation of the protrusion and the groove, thereby realizing the quick installation of the protective shell. Compared with the hinged method, the cooperation method of the protrusion and the groove makes the first curved outer plate abut against the outer wall of the second curved outer plate, and the second curved inner plate abuts against the outer wall of the first curved inner plate, so that the sealing between the first shell and the second shell is better.

[0014] Since a limit column is respectively provided at both ends of the first curved outer plate and the second curved outer plate, compared with all the limit columns being installed on the first curved outer plate, when each limit column is matched with the corresponding limit groove, the first shell and the second shell are both constrained on the limit sleeve, thereby making the assembly of the protective shell and the limit sleeve more stable.
