DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Embodiment 1: Figures 1 to 7 As shown, a cable fixing and sealing device for a power distribution cabinet described in the present invention includes a mounting portion, a limiting mechanism, a sealing mechanism, a cleaning mechanism and a control mechanism.

[0039] The installation part includes a distribution cabinet case 1 and a containing shell 2, wherein the containing shell 2 is fixedly installed on the inner wall of the distribution cabinet case 1, wherein the inner cavity of the distribution cabinet case 1 is used to install electrical appliances, and a through hole for cable insertion is provided at the bottom of the distribution cabinet case 1, and the cable passes through the containing shell 2 while passing through the distribution cabinet case 1.

[0040] The limiting mechanism includes a mounting frame 22 and a locking rod 9. The locking rod 9 is rotatably mounted on the upper end of the mounting frame 22. One end of the locking rod 9 is tilted, and the middle part is rotatably connected to the mounting frame 22 through a torsion spring.

[0041] When the cable passes through, the inclined end of the locking rod 9 fits against the outer wall of the cable, and the cable is unidirectionally locked by the locking rod 9, and then the cable is fixed after being connected to the electrical appliance in the distribution cabinet chassis 1.

[0042] The sealing mechanism includes a mounting tube 7 and an elastic tube 16. The mounting tube 7 is fixedly mounted on the inner wall of the accommodating shell 2. The elastic tube 16 is fixedly mounted on the inner wall of the mounting tube 7. The inner cavity of the mounting tube 7 is connected to the through hole at the bottom of the distribution cabinet chassis 1 for threading.

[0043] The elastic tube 16 is made of elastic rubber material, and the axial ends are fixedly connected to the inner wall of the elastic tube 16. The middle part of the elastic tube 16 bulges inward, and air is inflated into the gap between the elastic tube 16 and the installation tube 7, thereby controlling the expansion of the elastic tube 16 until the outer wall of the elastic tube 16 fits tightly with the insulating layer outside the cable, thereby achieving sealing after the cable is installed, preventing moisture and rainwater from entering the inner cavity of the distribution cabinet chassis 1 when used outdoors.

[0044] The cleaning mechanism includes a mounting ring 6 and an elastic layer 17, wherein the mounting ring 6 is fixedly mounted on the bottom surface of the accommodating shell 2, wherein the mounting ring 6 is connected to a through hole for threading at the bottom of the distribution cabinet chassis 1, and the elastic layer 17 is arranged inside the mounting ring 6, and the elastic layer 17 is made of a common sponge material. When the cable is inserted, the outer wall of the cable is wiped by the elastic layer 17, thereby removing dust and gravel on the outer wall of the cable, preventing the sand and gravel from scratching the elastic tube 16, and improving the service life of the elastic tube 16.

[0045] The control mechanism includes a control cylinder 10 and a control plug 14. The control plug 14 is slidably installed in the inner cavity of the control cylinder 10, wherein the outer wall of the control plug 14 is sealed and fitted with the inner wall of the control cylinder 10, and the inner cavity of the control cylinder 10 is divided into two chambers by the control plug 14.

[0046] Inside the control tube 10, the deformation of the elastic tube 16 is controlled by the air pressure in the cavity on one side of the control plug 14, and the deformation of the elastic layer 17 is controlled by the air pressure in the cavity on the other side of the control plug 14. By adjusting the sliding direction of the control plug 14, when the cable is inserted, the elastic layer 17 is controlled to expand and the elastic tube 16 is controlled to contract, thereby wiping the outer wall of the cable. After the cable is installed, the elastic tube 16 expands and the elastic layer 17 contracts, thereby achieving sealing of the cable.

[0047] As a preferred embodiment of the present invention, one axial end of the control cylinder 10 is fixedly connected to the outer wall of the mounting cylinder 7, thereby realizing the communication between the inner cavities of the mounting cylinder 7 and the control cylinder 10. When the control plug 14 slides toward one side of the mounting cylinder 7, the expansion of the control elastic cylinder 16 is realized.

[0048] A closing plate 13 is fixedly mounted on one end of the control cylinder 10 away from the mounting cylinder 7 , and a connecting portion 12 is provided on one side of the control plug 14 , through which the control plug 14 is pulled away from the mounting cylinder 7 .

[0049] One side of the control plug 14 is elastically connected to the outer wall of the closing plate 13. A spring is provided on the outer wall of the control plug 14. One side of the spring is connected to the outer wall of the closing plate 13. The elastic force of the spring pushes the control plug 14 so that the control plug 14 has a tendency to slide toward the mounting tube 7 in real time.

[0050] The connecting part 12 passes through the closing plate 13 and is sealedly connected to the closing plate 13 , wherein the connecting part 12 is composed of a rope and a hard rod, the hard rod is connected to the closing plate 13 , and a sliding seal is provided at the connecting position for achieving the closure of the inner cavity of the control cylinder 10 .

[0051] A support cylinder 11 is fixedly mounted on the inner wall of the accommodating shell 2 , and a winding disk 4 is rotatably arranged at one axial end of the support cylinder 11 , wherein the axis of the winding disk 4 coincides with the axis of the support cylinder 11 .

[0052] One end of the connection part 12 away from the control plug 14 is fixedly connected to the radial outer wall of the winding drum 4, and the rope end of the connection part 12 is connected to the outer wall of the winding drum 4. The winding drum 4 is rotated to pull the control plug 14 to slide through the winding connection part 12. At this time, the control plug 14 is away from the mounting tube 7.

[0053] A transmission shaft 20 is rotatably installed on the inner wall of the support cylinder 11, and the axis of the transmission shaft 20 coincides with the axial direction of the support cylinder 11. The radial outer wall of the transmission shaft 20 is connected to the inner wall of the support cylinder 11 through an elastic member, wherein the elastic member is a common torsion spring, one end of the torsion spring is fixedly connected to the radial outer wall of the transmission shaft 20, and the other end of the torsion spring is connected to the inner wall of the support cylinder 11, and the axial end of the transmission shaft 20 is fixedly connected to the axial end of the winding disk 4. After the winding disk 4 is rotated, the winding disk 4 is reset by the elastic force of the torsion spring.

[0054] A transmission gear 19 is fixedly mounted on the radial outer wall of the transmission shaft 20 , wherein the axis of the transmission gear 19 coincides with the axis of the transmission shaft 20 , and rotating the transmission gear 19 drives the transmission shaft 20 to rotate synchronously.

[0055] As a preferred embodiment of the present invention, a control rack 3 is slidably installed on the inner wall of the accommodating shell 2, one end of the control rack 3 extends to the inner wall of the supporting tube 11 and meshes with the transmission gear 19. The sliding control rack 3 drives the transmission gear 19 to rotate, thereby controlling the winding and unwinding of the winding disk 4.

[0056] One end of the control rack 3 extends to the outer wall of the accommodating shell 2. A door panel is installed on the outer wall of the distribution cabinet chassis 1 through a hinge. Before installing the cable, it is necessary to open the door panel first. At this time, the door panel is away from the control rack 3. At this time, the torsion spring controls the transmission shaft 20 to rotate, thereby rotating the winding drum 4. When the winding drum 4 rotates, the control plug 14 is pulled to slide through the connecting part 12. At this time, the elastic layer 17 expands to wipe off the sand and gravel when the cable is inserted.

[0057] After the cable connection is completed, the door panel needs to be closed. As the door panel is closed, the door panel presses against the control rack 3 to slide, which is used to control the reverse rotation of the winding disk 4. At this time, the control plug 14 is pushed to slide by the spring, thereby controlling the elastic tube 16 to expand until the outer wall of the elastic tube 16 fits with the outer wall of the cable, so as to achieve cable sealing.

[0058] An assembly frame for installing electrical appliances is fixedly installed on the inner wall of the distribution cabinet chassis 1, and a guide rod is fixedly installed on the outer wall of the control plug 14. The guide rod passes through the closing plate 13, and the outer wall of the guide rod is slidably fitted with the inner wall of the closing plate 13. By setting the guide rod, the sliding stability of the closing plate 13 is improved.

[0059] As a preferred embodiment of the present invention, an elastic membrane 18 is fixedly installed on the inner wall of the mounting ring 6, wherein the elastic membrane 18 is made of rubber, and both ends of the elastic membrane 18 are in contact with the inner wall of the mounting ring 6 to form a cavity with the inner wall of the mounting ring 6, and air is inflated into the cavity to control the expansion of the mounting ring 6.

[0060] The outer wall of the elastic membrane 18 fits with the inner wall of the elastic layer 17. When the elastic membrane 18 expands, it presses the elastic layer 17, thereby controlling the elastic layer 17 to fit with the cable. After the cable is connected, the gas in the elastic membrane 18 is extracted to control the elastic membrane 18 to shrink. At this time, the elastic layer 17 is separated from the outer wall of the cable to prevent the elastic layer 17 from absorbing water and becoming moldy and corroding the outer wall of the cable.

[0061] A buffer block 5 is fixedly installed on the inner wall of the accommodating shell 2. A cavity is arranged inside the buffer block 5, and the buffer block 5 is connected to the closing plate 13 through a conduit. The buffer block 5 is made of elastic rubber material. The other end of the buffer block 5 is connected to the inner cavity of the elastic membrane 18. The connection between the control cylinder 10 and the inner cavity of the elastic membrane 18 is achieved through the buffer block 5.

[0062] Since the volume of the inner cavity of the elastic membrane 18 is smaller than the volume of the cavity between the elastic tube 16 and the mounting tube 7 , the buffer block 5 is provided to balance the air pressure in the inner cavity of the elastic membrane 18 when the elastic membrane 18 expands.

[0063] A carrying ring 15 is fixedly mounted on the upper end surface of the accommodating housing 2 . The bottom of the carrying ring 15 is fixed to the upper end surface of the mounting tube 7 . The cable passes through the carrying ring 15 when inserted.

A plurality of mounting frames 22 are provided, and the plurality of mounting frames 22 are evenly distributed in a ring shape along the axis of the supporting ring 15, so that when the cable passes through, a plurality of contact points are formed on the outer wall of the cable, thereby improving the stability of the cable fixation.

[0065] A connecting ring 8 is fixedly mounted on the outer wall of the mounting tube 7 , a cavity is provided inside the connecting ring 8 , and a connecting shaft 21 is slidably mounted on the inner wall of the connecting ring 8 , wherein the connecting ring 8 provides an installation and sliding space for the connecting shaft 21 .

[0066] As a preferred embodiment of the present invention, one end of the connecting shaft 21 passes through the connecting ring 8 and extends to the upper end surface of the accommodating shell 2. One end of the locking rod 9 is rotatably connected to the upper end surface of the connecting shaft 21. The connecting shaft 21 is slid to control the sliding of the connecting shaft 21. The connecting shaft 21 is slid upward to press the locking rod 9 so that the other end of the locking rod 9 is in contact with the cable. The connecting shaft 21 is slid downward to pull the locking rod 9 so that the other end of the locking rod 9 is away from the cable.

[0067] The inner cavity of the communication ring 8 is communicated with the inner cavity of the installation tube 7 , so that the inner cavity of the communication ring 8 is communicated with the cavity between the installation tube 7 and the elastic tube 16 .

[0068] A guide cylinder 24 is fixedly mounted on the inner wall of the connecting ring 8 , a transmission plug 23 is slidably mounted on the inner wall of the guide cylinder 24 , and a sealing rubber is arranged on the outside of the transmission plug 23 , thereby achieving a sealed connection between the guide cylinder 24 and the connecting shaft 21 .

[0069] The upper end surface of the transmission plug 23 is fixedly connected to the bottom of the connecting shaft 21, so that when the door panel of the distribution cabinet chassis 1 is closed, the elastic tube 16 is controlled to expand. When the elastic tube 16 expands, the connecting shaft 21 is controlled to slide upward to press the locking rod 9 to fix the cable.
