Description

Technical Field

[0001] The present invention relates to the technical field of cable trench cover plate structures, and particularly to an anti-theft cable trench cover plate structure. Background Art

[0002] A cable trench is an underground pipeline used for laying and replacing power or telecommunications cable facilities, and is also an enclosure structure for the laid cable facilities. It has pipeline structure forms such as rectangular, circular, and arched. After the cables are laid, the cable trench needs to be closed by a cover plate to prevent the cables from being damaged.

[0003] An anti-theft cable trench cover plate and cable trench structure with the patent number CN115149486B adopts a structure in which a locking rod is vertically arranged downward on the cover plate and inserted into a cable fixing frame in the lower cable trench for locking and fixing to prevent theft. However, the cover plate of such a cable trench is relatively heavy, and it requires two workers to use hooks to lift the cover at the same time. The cooperation between the locking rod structure in the cover plate and the small hole below is relatively difficult, resulting in a relatively high accuracy requirement for the position where the cover plate needs to be closed. That is, to remove the cover plate from a fixed position, it must also be closed from the fixed position. If there is a slight deviation in the position, the locking rod structure in the cover plate cannot cooperate with the small hole below. For cable maintenance workers, it is very difficult to close it in place, and it is time-consuming and laborious, which is not conducive to the convenient closing operation of the cover plate.

[0004] Therefore, it is necessary to propose an anti-theft cable trench cover plate structure to improve the convenience of closing the cover plate on the basis of anti-theft, so as to facilitate workers to quickly close it. Summary of the Invention

[0005] In order to solve the above problems, the present invention proposes an anti-theft cable trench cover plate structure to improve the convenience of closing the cover plate on the basis of anti-theft, so as to facilitate workers to quickly close it.

[0035] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0036] Please refer to Figures 1-11, the present invention provides an anti-theft cable trench cover structure, including a cable trench 1, n cable fixing frames 2, n - 1 locking components 3, and multiple covers 4. The n cable fixing frames 2 are arranged in sequence and fixedly connected to the two pairs of inner walls of the cable trench 1. The two ends of one locking component 3 are respectively fixedly connected to the tops of two adjacent cable fixing frames 2. A fixing plate 21 is provided on the top of the cable fixing frame 2, and two threaded holes are symmetrically provided on the fixing plate 21. The two ends of one locking component 3 are respectively locked into the threaded holes by screws to be fixed on the fixing plates 21 of two adjacent cable fixing frames 2. The locking component 3 is in contact with the inner wall of the cable trench 1. A placement groove 11 is provided on the cable trench 1. The locking component 3 is provided with at least one engaging portion 31 and at least one unlocking portion 32. The unlocking portion 32 corresponds to the engaging portion 31 one by one. The engaging portion 31 extends into the placement groove 11. The cover 4 is received in the placement groove 11. A horizontal engaging groove 41 is provided at the bottom of the cover 4. The horizontal engaging grooves 41 are respectively engaged with at least one engaging portion 31 to lock the cover 4. In order to ensure that the cover 4 can be firmly covered, it is most appropriate that the number of the engaging portion 31 and the unlocking portion 32 is two respectively, that is, one cover 4 is locked by two locking components 3, that is, engaged through 4 engaging portions 31. A strip-shaped through groove 42 is provided on the cover 4. Among the positions where the horizontal engaging groove 41 can be engaged with all the unlocking portions 32, the unlocking portions 32 are all located at the bottom of the strip-shaped through groove 42. Pressing the unlocking portion 32 through the strip-shaped through groove 42 can drive the engaging portion 31 to unlock the horizontal engaging groove 41. A hook slot 43 is also provided on the cover 4 to facilitate the external hook to be hooked. After the cover 4 is unlocked, the worker can use the external hook to extend into the hook slot 43 to hook the cover 4 and then lift it to pull the cover 4 out of the placement groove 11.

[0037] In this embodiment, n cable fixing brackets 2 and n - 1 locking components 3 are pre - fitted. When the n cable fixing brackets 2 are arranged, they can fix the cables. Both ends of one locking component 3 are fixedly connected to the tops of two adjacent cable fixing brackets 2, so that the locking component 3 is fixed in the cable trench 1 relying on the fixing force of the cable fixing brackets 2 and is directly locked and fixed with the cover plate 4 without the need for additional drilling and fixing in the cable trench 1, which is convenient for installation. When being locked and fixed with the cover plate 4, the engaging portion 31 on the locking component 3 will form an engaging connection with the engaging transverse groove 41 at the bottom of the cover plate 4. Since the engaging transverse groove 41 has a certain length, the engaging transverse groove 41 can cover all the engaging portions 31 for engagement. When covering the cover plate 4, the cover plate 4 needs to be placed in the placement groove 11. Even if the placement position of the cover plate 4 has a deviation to the left or right compared with the position where it was lifted before, as long as it is within the position where the engaging transverse groove 41 can form an engaging connection with all the engaging portions 31, the cover plate 4 can be immediately locked and fixed after being placed in the placement groove 11. For example, the length of the engaging transverse groove 41 is 36 cm, and the straight - line length formed by connecting all the engaging portions 31 is 30 cm, that is, the deviation distance of the cover plate 4 to the left or right can be 6 cm. At the same time, after the cover plate 4 is locked and fixed, the unlocking portion 32 is also located at the bottom of the strip - shaped through - groove 42, that is, the length of the strip - shaped through - groove 42 can also allow a deviation distance of 6 cm for the cover plate 4 to the left or right. When it is necessary to unlock the cover plate 4, an external long rod can be used to pass through the strip - shaped through - groove 42 and press the unlocking portion 32. After the unlocking portion 32 is pressed, it can drive the engaging portion 31 to unlock the engaging transverse groove 41, and finally unlock the cover plate 4, which is convenient and fast;

[0038] In summary, the anti - theft cable trench cover plate structure can effectively prevent theft and at the same time improve the convenience degree when the cover plate is covered, so as to facilitate the workers to cover it quickly.

[0039] In this embodiment, the unlocking portion 32 includes a first fixed housing 321, a sliding column 322, a pressing member 323, a first elastic member 324, and a magnetic attraction positioning assembly 325. The engaging portion 31 is fixedly connected to one side of the first fixed housing 321. The pressing member 323 is sleeved on the sliding column 322. Both the sliding column 322 and the pressing member 323 are longitudinally slidably connected to the first fixed housing 321. One end of the pressing member 323 extends toward the engaging portion 31 and contacts the engaging portion 31. One end of the first elastic member 324 abuts against the bottom of the pressing member 323, and the other end of the first elastic member 324 abuts against the inside of the first fixed housing 321. The magnetic attraction positioning assembly 325 is transversely slidably connected to the first fixed housing 321 and is located below the sliding column 322. The magnetic attraction positioning assembly 325 maintains a preset distance from the sliding column 322. Pressing the sliding column 322 downward can drive the pressing member 323 to slide downward and push the engaging portion 31 to flip outward. Both the sliding column 322 and the pressing member 323 are made of metal materials. After the sliding column 322 is pressed to the end, the bottom of the sliding column 322 forms magnetic attraction fixation with one end of the magnetic attraction positioning assembly 325, so that the engaging portion 31 unlocks the engaging transverse groove 41; when it is necessary to unlock the cover plate 4, an external long rod can be used to pass through the strip-shaped through groove 42 and then press the sliding column 322. During the pressing process of the sliding column 322, the pressing member 323 will gradually slide downward, and at the same time, push the engaging portion 31 to gradually flip toward the outside of the engaging transverse groove 41. After the bottom of the sliding column 322 forms magnetic attraction fixation with one end of the magnetic attraction positioning assembly 325, the engaging portion 31 is inclined at a preset angle with the vertical plane. At this time, the engaging portion 31 unlocks the engaging transverse groove 41, and the first elastic member 324 is compressed to the shortest. At this time, the cover plate 4 can be pulled up and opened. When it is necessary to restore the position of the engaging portion 31, the magnetic attraction positioning assembly 325 needs to be slid in a direction away from the sliding column 322, so that the magnetic attraction effect between one end of the magnetic attraction positioning assembly 325 and the bottom of the sliding column 322 is separated under the misalignment pulling force. After the misalignment separation, the first elastic member 324 is restored under its own elastic force, and at the same time drives the pressing member 323 and the sliding column 322 to slide upward, finally causing the sliding column 322 and the pressing member 323 to return to their original positions. After the pressing member 323 returns to its original position, the engaging portion 31 is no longer pushed by the pressing member 323, and the engaging portion 31 will return to the vertical state under its own elastic force. At this time, the engaging portion 31 has completed the position restoration. After the cover plate 4 is placed down into the placement groove 11, the engaging portion 31 directly engages and connects with the engaging transverse groove 41.

[0040] In this embodiment, a first sliding groove 3211, a second sliding groove 3212, and a receiving groove 3213 are provided in the first fixed housing 321. The first sliding groove 3211 communicates with the second sliding groove 3212, and the second sliding groove 3212 communicates with the receiving groove 3213. One end of the sliding column 322 is received in the receiving groove 3213, and the other end of the sliding column 322 is received in the first sliding groove 3211. The second sliding groove 3212 faces the engaging portion 31. One end of the pressing member 323 is received in the receiving groove 3213, and the other end of the pressing member 323 extends outwards from the second sliding groove 3212 and contacts one side of the engaging portion 31. The first elastic member 324 is received in the receiving groove 3213. The first sliding groove 3211 is used to provide a stable sliding structure for the sliding column 322, the second sliding groove 3212 is used to provide an up-and-down sliding structure for the pressing member 323, and the receiving groove 3213 is used to provide a placement space for the first elastic member 324. When installing the sliding column 322, the pressing member 323, and the first elastic member 324, first sleeve the pressing member 323 on the sliding column 322, then fix one end of the first elastic member 324 to the bottom of the pressing member 323, and then align the sliding column 322 with the first sliding groove 3211 and insert it into the first sliding groove 3211. After the top of the sliding column 322 and the pressing member 323 are both received in the receiving groove 3213, the sliding column 322 can be covered with the limiting cover 326 to enable the smooth installation of the sliding column 322, the pressing member 323, and the first elastic member 324. A through hole 3261 is provided in the middle of the limiting cover 326, and a protruding end 3222 is provided at the top of the sliding column 322. The protruding end 3222 is received in the through hole 3261. When pressing the sliding column 322, the protruding end 3222 can be pressed by an external long rod, so that the protruding end 3222 sinks relative to the through hole 3261. At this time, the sliding column 322 slides towards the first sliding groove 3211, and at the same time drives the pressing member 323 to slide downwards in the second sliding groove 3212.

[0041] In this embodiment, a contact pulley 3231 is provided at one end of the pressing member 323. The contact pulley 3231 is in inclined contact with one side of the engaging portion 31. When the pressing member 323 slides down, the contact pulley 3231 also moves vertically downwards. During the downward movement of the contact pulley 3231, it will push the engaging portion 31 to gradually flip towards the outside of the engaging transverse groove 41 under the condition of the inclined surface of the engaging portion 31 itself.

[0042] In this embodiment, a displacement groove 3214 is provided in the first fixed housing 321. The displacement groove 3214 is located at the bottom of the first sliding groove 3211 and is in communication with the first sliding groove 3211. One end of the magnetic attraction positioning component 325 is received in the displacement groove 3214 and is slidably connected to the groove wall of the displacement groove 3214. The displacement groove 3214 is used to provide a sliding guiding structure for one end of the magnetic attraction positioning component 325. When the engaging portion 31 needs to be restored to its original position, the magnetic attraction positioning component 325 needs to be slid in a direction away from the sliding column 322, that is, the magnetic attraction positioning component 325 needs to be slid backward in the displacement groove 3214, so that the magnetic attraction effect between one end of the magnetic attraction positioning component 325 and the bottom of the sliding column 322 is separated under the condition of misalignment tension.

[0043] In this embodiment, the magnetic attraction positioning component 325 includes a fixed block 3251, a connecting block 3252, a third elastic member 3253, and a handle 3254. One end of the fixed block 3251 is received in the displacement groove 3214. One end of the fixed block 3251 forms a magnetic attraction fixation with the bottom of the sliding column 322. The other end of the fixed block 3251 is fixedly connected to one end of the connecting block 3252. One end of the third elastic member 3253 is fixedly connected to the other end of the connecting block 3252. A third sliding groove 3215 is provided in the first fixed housing 321. The connecting block 3252 is received in the third sliding groove 3215 and is slidably connected to the groove wall of the third sliding groove 3215. The other end of the third elastic member 3253 abuts against the groove wall of the third sliding groove 3215. The handle 3254 is fixedly connected to one side of the connecting block 3252 and extends outside the first fixed housing 321. In order to be able to be pulled smoothly after being connected to the fixed block 3251, the connecting block 3252 is in an L-shaped structure. When the engaging portion 31 needs to be restored to its original position, the handle 3254 can be held by hand to pull the connecting block 3252 backward, so that the connecting block 3252 drives the fixed block 3251 to slide backward. At this time, the third elastic member 3253 is compressed and stores energy, and finally the magnetic attraction effect between the connecting block 3252 and the bottom of the sliding column 322 is separated under the condition of misalignment tension. After the magnetic attraction effect is separated, the fixed block 3251 slides forward under the restoring elastic force of the third elastic member 3253 and finally stays at the bottom of the first sliding groove 3211 to prepare for magnetic attraction when the sliding column 322 is pressed next time.

[0044] In this embodiment, a first magnet 3221 is provided at the bottom of the sliding column 322, and a second magnet 32511 is provided at one end of the fixed block 3251. The second magnet 32511 is located at the bottom of the first sliding groove 3211 and is aligned with the first sliding groove 3211. The first magnet 3221 and the second magnet 32511 are magnetically fixed; when the sliding column 322 slides downward to the end, the first magnet 3221 and the second magnet 32511 are magnetically attracted, and the magnetic attraction force between the first magnet 3221 and the second magnet 32511 is greater than the sum of the elastic force of the first elastic member 324 and the elastic force of the engaging portion 31 itself, so that the sliding column 322 can maintain its position at the end after sliding downward to the end.

[0045] In this embodiment, the hooking portion 31 includes a second fixed shell 311, a hooking member 312, a sliding block 313, and a second elastic member 314. The second fixed shell 311 is fixedly connected to one side of the first fixed shell 321, one end of the hooking member 312 is rotatably connected to the second fixed shell 311, one side of the unlocking portion 32 contacts one side of the hooking member 312, and the other end of the hooking member 312 extends upward and forms a hooking connection with the hooking transverse groove 41. The second fixed shell 311 is provided with an installation cavity 3111, and the sliding block 313 and the second elastic member 314 are both accommodated in the installation cavity 3111. The sliding block 313 forms a longitudinal sliding connection with the inner wall of the installation cavity 3111. The second end of the second elastic member 314 is fixedly connected to the bottom of the sliding block 313, and the other end of the second elastic member 314 is fixedly connected to the bottom of the mounting cavity 3111. The hook member 312 is provided with a prying contact end 3121, and the prying contact end 3121 abuts against the upper surface of the sliding block 313. When the hook portion 31 is hooked with the hooking transverse groove 41, the hook member 312 is vertically arranged under the elastic abutment formed upwardly by the second elastic member 314 to form an elastic force behind the sliding block 313. At this time, the hooking transverse groove 41 is hooked, the cover plate 4 is locked, and the cover plate 4 cannot be pulled up. When it is necessary to release the lock, the protrusion can be lifted by an external long rod. The first and second magnets 3221 and 3251 are pressed against the top of the sliding block 313, and the second magnets 3221 and 3251 are pressed against the top of the sliding block 313, so that the second elastic member 314 is compressed and stored by the downward movement of the sliding block 313, and a magnetic attraction is formed between the first magnet 3221 and the second magnet 32511. After fixation, the hook member 312 has a maximum flipping angle. At this time, the hook member 312 is tilted, and the sliding block 313 continues to apply upward force to the prying contact end 3121 under the elastic force of the second elastic member 314. After the first magnet 3221 and the second magnet 32511 are released from the magnetic attraction, the pressing member 323 slides upward and cancels the thrust on one side of the hook member 312, so that the prying contact end 3121 in the hook member 312 is pushed upward by the sliding block 313 under the restoring elastic force of the second elastic member 314, and then the hook member 312 is restored to a vertical state, and can now be hooked and connected with the hooking transverse groove 41.

[0046] In this embodiment, the engaging member 312 includes a connecting plate 3122 and an engaging plate 3123. The connecting plate 3122 and the engaging plate 3123 are fixedly connected in an L-shaped structure. One end of the connecting plate 3122 is rotatably connected to the second fixed shell 311. The prying contact end 3121 is located between the connecting plate 3122 and the engaging plate 3123. One end of the engaging plate 3123 extends upward and forms an engaging connection with the engaging transverse groove 41. One side of the unlocking portion 32 is in contact with one side of the engaging plate 3123. The connecting plate 3122 is connected to the second fixed shell 311 by means of hinging. When the pressing member 323 slides downward and pushes the engaging plate 3123, the engaging plate 3123 will rotate outward with the hinged position of the connecting plate 3122 as the rotation center, so that the engaging plate 3123 disengages from the engaging transverse groove 41 and is in an inclined state. When the pressing member 323 slides upward and cancels the thrust on the engaging plate 3123, the sliding block 313 pushes the prying contact end 3121 to move upward under the elastic force of the second elastic member 314, so that the engaging plate 3123 rotates inward with the hinged position of the connecting plate 3122 as the rotation center to restore the vertical state.

[0047] In this embodiment, an inclined boss 31231 is provided on one side of the engaging plate 3123. The inclined boss 31231 faces the unlocking portion 32. A transmission inclined surface 301 is provided on the inclined boss 31231. The included angle between the transmission inclined surface 301 and the vertical plane is 12 to 15 degrees. The transmission inclined surface 301 is in contact with the unlocking portion 32. The transmission inclined surface 301 is used to provide a structure for the downward sliding of the pressing member 323 to make the engaging plate 3123 inclined. When the pressing member 323 slides downward, the pressing member 323 pushes the inclined boss 31231 laterally. The lower the pressing member 323 moves, the more inclined the inclined boss 31231 will be under the guiding action of the transmission inclined surface 301 on the pressing member 323, so that the engaging plate 3123 is in an inclined state.

[0048] Of course, the present invention can also have many other embodiments. Based on this embodiment, other embodiments obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present invention.
