[0032] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0033] like Figure 1-Figure 6 As shown, the present invention provides a cable closing sleeve and a method of using the same. The device comprises: a sleeve 1 2 and a sleeve 2 3. A guide groove 6 is arranged on the outer circumference of one end of the sleeve 1 2. A connecting sleeve 4 is installed on the outer circumference of one end of the sleeve 2 3. The guide groove 6 and the connecting sleeve 4 are adaptively matched. The sleeve 1 2 and the sleeve 2 3 are connected by the engagement of the guide groove 6 and the connecting sleeve 4. A plurality of holes are symmetrically arranged on the outer surfaces of one side of the sleeve 1 2 and the sleeve 2 3. A constraint base 13 is arranged in the holes. The constraint base 13 on the sleeve 1 2 is connected to the constraint base 2 141. The constraint base 13 on the sleeve 2 3 is connected to the constraint base 1 14. The constraint base 14 and the constraint base 2 141 are engaged and connected to fix the sleeve 1 2 and the sleeve 2 3. The inner surfaces of the cavities of the sleeve 1 2 and the sleeve 2 3 pass through the cable to protect the cable.

[0034] Preferably, both sleeve 1 2 and sleeve 2 3 can be provided with a constraint base 14 at one end and a constraint base 2 141 at the other end, so as to realize continuous clamping of multiple sleeves and quickly adjust the sleeve length according to the cable length.

[0035] An expansion pad groove 61 is arranged on the outer peripheral surface in the center of the guide groove 6 and lip-shaped rubber ring grooves 62 are arranged on both sides. A lip-shaped rubber ring 7 is arranged at the position of the lip-shaped rubber ring groove 62 of the sleeve 1 2. An expansion pad 9 is installed at the position of the expansion pad groove 61 on the inner peripheral surface of the connecting sleeve 4 after the sleeve 2 3 is engaged with the sleeve 1 2.

[0036] like Figure 5 and Figure 6 As shown, the expansion pad 9 is a circular structure and gas is arranged inside. The outer surface of the expansion pad 9 is fixedly connected to the inner circumference of the connecting sleeve 4. The expansion pad 9 is connected to the gas transmission channel 10 passing through the outer surface of the connecting sleeve 4. At the same time, the outer wall of the connecting sleeve 4 is provided with an opener and a closeer 11 which is communicated with the gas transmission channel 10. The increase and decrease of the gas in the expansion pad 9 can be controlled by opening and closing the opener and the closeer 11. The opener and the closeer 11 is provided with a pressure transmitter 19, which can monitor the pressure of the expansion pad 9 and improve safety. At the same time, a sealing glue 18 is provided at the connection between the opener and the outer circumference of the connecting sleeve 4 to improve the impermeability and connection stability.

[0037] Preferably, a protective shell can be provided at the position of the shutter 11 on the connecting sleeve 4 to protect the shutter 11 .

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, the constraint base 13 includes: a constraint sleeve 132, a constraint sleeve 133 and a constraint sheet 134. The constraint sleeve 132 and the constraint sheet 134 are fixedly connected at the center of one side, and the constraint sleeve 133 and the constraint sheet 134 are fixedly connected at the center of the other side. The constraint sleeve 132 and the constraint sleeve 133 are in the same straight line. The constraint sleeve 133 is provided with a guide groove 135 inside. The guide groove 135 is provided with an inner thread. The constraint sheet 134 is provided with a central thread and the constraint sleeve 133 is provided with a guide groove 135.

At the same time, the four corners of the constraint plate 134 are provided with limit openings 136. Bolts pass through the limit openings 132 to fix the constraint plates 134 to the ends of sleeve 1 2 and sleeve 2 3 respectively. The constraint base 13 is embedded in sleeve 1 2 and sleeve 2 3. The constraint base 13 does not extend from the ends of sleeve 1 2 and sleeve 2 3, so that sleeve 1 2 and sleeve 2 3 are more tightly connected.

[0039] The constraint base 14 is arranged in the constraint base 13 on the sleeve 23, and the constraint base 14 includes: a guide bar 142 and a connecting plate 143, wherein the outer surface of the guide bar 142 is provided with an outer thread, and the outer thread on the guide bar 142 is adaptively matched with the inner thread on the guide groove 135, and the guide bar 142 is screwed with the guide groove 135 through the inner and outer threads, so that the constraint base 13 and the constraint base 14 are fixedly connected, and the other end of the guide bar 142 is fixedly connected with the connecting plate 143, and the connecting plate 143 is larger than the guide groove. The size of 135 is slightly larger, so that the guide strip 142 stops rotating automatically when it rotates to a certain extent, which is convenient for the staff to operate. The other end of the connecting plate 143 is connected to the connecting strip 146. A female buckle 144 is arranged at the end of the connecting strip 146. The female buckle 144 is a cylindrical sleeve with a plurality of linear grooves evenly arranged in the circumferential direction. The outer peripheral surface of the end of the female buckle 144 has a protrusion that can clamp the male buckle 145. Through the limitation of the connecting plate 143, when the guide strip 142 stops rotating, the female buckle 144 will extend out from the end of the sleeve 23.

[0040] The constraint base 13 on the sleeve 1 is provided with a constraint base 141, and the constraint base 141 includes: a guide bar 142 and a connection plate 143, the outer surface of the guide bar 142 is provided with an outer thread, the outer thread on the guide bar 142 and the inner thread of the guide groove 135 on the constraint base 13 are adaptively matched, the guide bar 142 is screwed with the guide groove 135 through the inner and outer threads, so that the constraint base 13 and the constraint base 141 are fixedly connected, and the other end of the guide bar 142 is fixedly connected with the connection plate 143, and the connection plate 143 is larger than the guide groove. The size of 135 is slightly larger, so that the guide strip 142 stops rotating automatically when it rotates to a certain extent, which is convenient for the staff to operate. The other end of the connecting plate 143 is connected to the connecting strip 146. A male buckle 145 is set at the end of the connecting strip 146. The male buckle 145 is a hemispherical structure. The plane side of the male buckle 145 is fixedly connected to the connecting strip 146. The radius of the male buckle 145 is slightly larger than that of the female buckle 144. Through the limitation of the connecting plate 143, when the guide strip 142 stops rotating, the male buckle 145 is embedded in the sleeve 2 and does not extend from the end of the sleeve 2.

[0041] Under the limitation of the connecting plate 143, the female buckle 144 will extend out from the end of the sleeve 2 3, and the male buckle 145 will be embedded in the sleeve 1 2. When the male buckle 145 is inserted into the inner cavity of the female buckle 144, the protruding part of the female buckle 144 will extend into the constraint sleeve 1 132 on the constraint base 13 where the male buckle 145 is located, so that the sleeve 1 2 and the sleeve 2 3 are tightly fitted without any gap.

[0042] In a specific embodiment, the side of sleeve 12 with constraint base 2 141 moves toward the side of sleeve 2 3 with constraint base 14, until the male buckle 145 fits with the female buckle 144. Because the male buckle 145 is hemispherical, the male buckle 145 slides toward the inner cavity of the female buckle 144 until the male buckle 145 is inserted into the female buckle 144 for snap connection. The protrusion at the end of the female buckle 144 clamps the male buckle 145 to improve the stability of the connection. Sleeve 1 2 and sleeve 2 3 fit tightly, realizing simple and quick snap connection between sleeve 1 2 and sleeve 2, facilitating quick adjustment of the sleeve length according to the cable length, and improving the efficiency of cable sleeve setting.

[0043] like Figure 5 As shown, the outer circumferential surface of one end of sleeve 2 3 is fixedly connected to the connecting sleeve 4 by bolts, so that the connecting sleeve 4 is fixed on the outer wall of sleeve 2 3 and extends from the end of sleeve 2 3. Sleeve 2 3 is provided with a rubber ring 16 installed at one end of the connecting sleeve 4. At the same time, a rubber pad 17 is installed on the end of sleeve 1 2 connected to sleeve 2 3 to improve the sealing after connection. The two lip-shaped rubber rings 7 on the guide groove 6 and the inner wall of the connecting sleeve 4 are sealed to prevent penetration.

[0044] Preferably, a sealing glue 18 may be provided on the inner surface of the connection between the sleeve 1 2 and the sleeve 2 3 for sealing, so as to further improve the sealing property and the anti-seepage property.

[0045] The present invention also provides a method for using the cable sealing sleeve, comprising the following steps:

[0046] Step 1: Fix the connecting sleeve 4 to the outer peripheral surface of the end of the sleeve 2 3 by bolts;

[0047] Step 2: The sleeve 1 2 passes through the connecting sleeve 4, and the sleeve 1 2 and the sleeve 2 3 are fixed by the clamping connection of the male buckle 145 and the female buckle 144;

[0048] Step 2.1: The side of the sleeve 1 2 with the constraint base 2 141 moves toward the side of the sleeve 2 3 with the constraint base 1 14 until the male buckle 145 fits with the female buckle 144;

[0049] Step 2.2: Continue to move the male buckle 145 toward the inner cavity of the female buckle 144 until the male buckle 145 is inserted into the female buckle 144 for snap connection;

[0050] Step 2.3: The protrusion at the end of the female buckle 144 clamps and fixes the male buckle 145;

[0051] Step 3: Open the shutter 11 to add gas to the inside of the expansion pad 9, so that the expansion pad 9 becomes larger and fits tightly against the inner circumference of the connecting sleeve 4;

[0052] Step 4: Close the shutter 11 and pass the cable through the middle of sleeve 1 2 and sleeve 2 3.

[0053] The beneficial effect of the present invention lies in that, compared with the prior art, the present invention fixes sleeve one and sleeve two by snapping together a male buckle and a female buckle, and the female buckle slightly protrudes from the end of sleeve two, so that after the male buckle and the female buckle are snapped together, sleeve one and sleeve two are still tightly fitted, and the first layer of anti-seepage sealing is performed, and the connecting sleeve is fixed on the outer peripheral surface of the end of sleeve two, and the lip-shaped rubber ring on sleeve one is pressed in by the inner wall of the connecting sleeve to perform the second layer of anti-seepage sealing, and the rubber ring at the end of sleeve two is sealed with the rubber pad on sleeve one to perform the third layer of anti-seepage sealing, and at the same time, sealing glue is provided on the inner surface of the connection between sleeve one and sleeve two to perform the fourth layer of anti-seepage sealing, and the increase of gas in the expansion pad is controlled by the opening and closing of the opener and the closeer, so that the expansion pad becomes larger and fits tightly with the connecting sleeve to perform the fifth layer of anti-seepage sealing, and the sealing effect of the sleeve is greatly improved through the multi-layer anti-seepage sealing, thereby preventing the cable from being corroded by moisture.

[0054] At the same time, the device realizes convenient and quick connection between sleeve one and sleeve two through the clamping connection of the female buckle and the male buckle, which is convenient for the staff to adjust the length of the sleeve according to the cable length, improves the efficiency of cable sleeve setting, and improves versatility.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
