[0062] DETAILED DESCRIPTION

[0063] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0064] The present invention provides a lifting vehicle assembly, referring to Figure 5 , Figure 6 as well as Figure 8-Figure 11 , including a track frame 1 and a carrier 2; the carrier 2 is directly connected to the track frame 1, and the carrier 2 can move along the height direction of the track frame 1.

[0065] The track frame 1 includes a frame column 11, and a carrier rail 112 extends from the frame column 11; the frame column 11 can be integrally formed with the carrier rail 112. The carrier 2 is a single-layer structure that accommodates and bears loads. Specifically, the carrier 2 includes a bottom plate 22 and a carrier column 21; the bottom plate 22 is connected to the carrier column 21, and the bottom plate 22 is used to carry people and / or goods; a carrier guide assembly 3 extends from the carrier; the carrier rail 112 is connected to the carrier 2 through the carrier guide assembly 3.

[0066] In a preferred embodiment, Figure 6 and Fig.10 As shown, the side projection of the frame column 11 overlaps with the side projection of the vehicle column 21. Compared with the solution in the prior art that requires a separate car frame, since there is no car frame, the side projection of the frame column can overlap with the side projection of the vehicle column, which means that the track frame and the vehicle column are closer, that is, the vehicle can be deeper. In other words, the present invention increases the area of ​​the vehicle by increasing the depth of the vehicle. Fig. 9 As shown, the carrier column 21 includes a carrier column body 211 and a carrier guide assembly mounting position 212;

[0067] In a preferred embodiment, Fig.10 As shown, the side projection of the carrier guide assembly 3 overlaps with the side projection of the carrier column 21. The carrier guide assembly 3 is a roller structure, specifically, the carrier guide assembly 3 includes a mounting block 31 and a carrier guide roller 32, the number of the carrier guide rollers 32 is 3, and the 3 carrier guide rollers 32 are installed in the carrier guide assembly installation position 212 through the mounting block 31; two of the carrier guide rollers 32 are respectively located on both sides of the carrier guide rail 112, clamping the carrier guide rail 112, and the other guide roller 32 is arranged vertically with the other guide rollers 32, and is against the end face of the carrier guide rail 112, and is attached to the end face of the carrier guide rail.

[0068] In a preferred embodiment, Fig. 9As shown, the vertical projection of the carrier column body 211 is an L-shaped structure, and the carrier column body 211 is provided with a column side opening groove group, a column first side nut groove 214, a carrier guide assembly mounting position 212, a column rear nut groove 215 and a column rear opening groove group in sequence; the column side opening groove group includes a first column side opening groove 213 and a column second side nut groove 216, and the column rear opening groove group includes a column first rear opening groove 217 and a column second rear opening groove 218 arranged parallel to each other. The carrier guide assembly installation position 212 is located at the corner of the L-shaped structure. The carrier guide assembly installation position 212 is also an L-shaped structure, and the L-shaped long side of the carrier guide assembly installation position 212 is an open structure, and the first column side opening groove 213 and the column second side nut groove 216 overlap in the width direction; the column first rear opening groove 217 and the column second rear opening groove 218 overlap in the depth direction; the column side opening groove 213 is used to insert glass or photoelectric safety devices or install fixed brackets; the closed part of the column second rear opening groove 218 is used to install light strips or install fixed brackets, and the open part is used to insert glass; the column first rear opening groove 217 is used to accommodate cables. Since the column first rear opening groove 217 is an open structure, the cable can be pushed into the cavity horizontally. Compared with threading in a closed cavity, the difficulty and working time of installation and maintenance are significantly reduced (because there are multiple large-sized connectors in the prefabricated cable, it is easy to get stuck during the threading process). After the glass is installed in the second rear opening groove 218 of the column, the L-shaped cable trough shield is inserted and pressed into the glass pressure strip, and the cable trough shield is fixed and covers the first rear opening groove 217 of the column. Since the carrier column body 211 has a large cross-sectional area, principal moment of inertia and bending section coefficient, and its cross section is provided with a column second side nut groove 216, column first side nut strip groove 214, carrier guide assembly installation position 212, column rear nut strip groove 215, column second rear opening groove 218, a total of 6 nut strip grooves for side connection (carrier guide assembly installation position 212 has 1 each in the depth and width direction), there are many locking positions and they are reasonably distributed, and the locking is firm, so when it is locked with the car bottom and possibly also the car top, the carrier can directly bear and transmit the load, so a separate car frame is no longer required, and it can be designed as a very compact single-layer structure.

[0069] The number of the frame columns 11 is one or more, and the number of the carrier columns 21 is the same as the number of the frame columns 11. In a preferred embodiment, Figure 5As shown, the track frame 1 also includes a track frame body 10; the carrier 2 also includes a carrier structure 20; the number of frame columns 11 is 2, namely the first frame column and the second frame column, the first frame column and the second frame column are respectively located at the two top ends of the track frame body 10 in the circumferential direction; and the first frame column and the second frame column are symmetrically arranged with each other; the number of carrier columns 21 is 2, namely the first carrier column and the second carrier column, the first carrier column and the second carrier column are respectively located at the two top ends of the carrier structure 20 in the circumferential direction; and the first carrier column and the second carrier column are symmetrically arranged with each other; the first frame column and the first carrier column are connected to each other through a carrier guide assembly 3, and the second frame column and the second carrier column are connected to each other through another carrier guide assembly 3.

[0070] The carrier may be a car or platform structure 6 of an elevator. In a preferred example where the carrier is a car, the first carrier column and the second carrier column are both rear columns of the car structure; the first frame column and the second frame column are both rear columns of the track frame 1. Figure 7 The lifting vehicle may also be a rectangular platform structure 6, and the connection method between the platform structure 6 and the track frame 1 may be any of the following: only one side of the platform is connected to the track frame 1, and the track frame 1 is located at both ends of one side of the platform, and the other side of the platform is a free end; or both sides of the platform are connected to the track frame 1, and the two connection points between the platform and the track frame 1 are in the middle of both sides of the platform.

[0071] like Figure 8 As shown, the vertical projection of the frame column 11 is U-shaped, and the frame column 11 is provided with a counterweight sealing plate groove 101, a light strip groove 102, a counterweight guide wheel groove 103, a first sealing plate or glass installation groove 104, a first splicing nut strip groove 105, a first wire groove 106, a first anti-fastener rotation limiting groove 107, a second wire groove 1061, a second anti-fastener rotation limiting groove 1071, a second splicing nut strip groove 1051, and a second sealing plate or glass installation groove 1041. The counterweight guide wheel groove 103 is a U-shaped structure. Bolt hole guide wire grooves 108 are provided beside the first anti-fastener rotation limiting groove 107 and the second anti-fastener rotation limiting groove 1071. When the frame column 11 is opened along the guide wire to fix the fastener, the bolt head or nut located in the column will be restricted from rotating by the limiting groove, so there is no need to hold it separately. A first installation and splicing positioning hole 109 is opened beside the second wire groove 1061 , and the first installation and splicing positioning hole 109 is communicated with the second wire groove 1061 .

[0072] In the preferred example where the carrier is an elevator car, the carrier structure 20 car includes a wall panel 23 and a car roof, that is, the carrier 2 is a car composed of a carrier column 21, a bottom plate 22, a wall panel 23 and a car roof. In a preferred example, the wall panel 23 is integrally connected to the carrier column 21. At this time, the present invention can be understood as a single-layer load-bearing car box that can withstand eccentric loads and does not have a separate car frame. The carrier guide assembly 3 can extend from the carrier column 21, or from the bottom plate 22, the wall panel 23 or the car roof. In addition, the car can also be suspended by the car roof. In this preferred example, the carrier guide rail 112 is located at two ends of the same side of the car body, and the carrier guide assembly 3 is directly fixed to the top, middle or lower part of the carrier column 21. The elevator also includes a light strip, a counterweight sealing plate 7 and a rear side sealing plate, such as Figure 5 shown.

[0073] like Fig.11 As shown, in the preferred example where the carrier is an elevator car, the lifting carrier assembly further includes a counterweight structure 4, and a counterweight guide assembly 5 is installed on the counterweight structure 4 through a support frame; counterweight guide assemblies 5 are provided at both ends of the counterweight structure 4. Preferably, the counterweight guide assembly 5 includes a counterweight guide roller 51, and the number of the counterweight guide rollers 51 is 2, and the two counterweight guide rollers 51 are arranged perpendicular to each other, one counterweight guide roller 51 is in contact with the bottom of the counterweight guide wheel groove 103 of the track frame 1, and the other counterweight guide roller 51 is in contact with the two sides of the counterweight guide wheel groove 103. In the present invention, since the counterweight guide wheel groove 103 is designed as a U-shaped structure, it can achieve the guidance in the front and rear directions by cooperating with one roller, thereby reducing the requirements of the counterweight guide assembly device on the depth space occupied.

[0074] Compared with the prior art, the present invention omits the backpack frame in order to expand the volume of the car, but the original functions of the backpack frame (such as realizing the up and down movement of the car, bearing and transmitting loads) need to be retained, so the structure of the car needs to be redesigned, which is extremely difficult.

[0075] The lifting vehicle assembly also includes a height-reducing cable fixing structure, wherein the cable includes a steel belt or a steel wire rope, and the height-reducing cable fixing structure is used to connect the steel belt 506 or the steel wire rope in the elevator to the car top.

[0076] The reduced height cable fixing structure can be any one of the following two structures:

[0077] Height reduction cable fixing structure 1:

[0078] like Fig.12 , Fig.13As shown, the height-reducing cable fixing structure utilizes the principle of Euler's formula. Specifically, the height-reducing cable fixing structure includes a round tube crossbeam 501, a rope head rod 502, a fixing device 503, and an inspection device 505; the fixing device 503 is a rope head pressure plate.

[0079] The round tube beam 501 is located inside the elevator car roof and is the crossbeam of the car roof. The steel belt 506 is suspended on the round tube beam 501. The round tube beam 501 is a round tube structure. In a preferred embodiment, since the round tube beam 501 and the rope head rod 502 are subjected to the rotation force of the steel belt, in order to prevent the round tube beam 501 and the rope head rod 502 from rotating, an anti-rotation structure is also provided on the round tube beam 501 and the rope head rod 502.

[0080] In a preferred embodiment, a cable entry guide device 507 is provided on the circular tube cross beam 501 at the entry side of the steel belt 506 to ensure that the position where the steel belt enters the car top is at the center of the car;

[0081] After the steel belt passes around the round tube crossbeam 501 , it passes around the rope end rod 502 to become the end of the steel belt. The rope end pressure plate fixes the steel belt 506 passing around the rope end rod 502 to the car top; specifically, the rope end pressure plate fixes the steel belt 506 passing around the rope end rod 502 to the round tube crossbeam 501 .

[0082] In a preferred embodiment, a cable fixing guide device 508 is provided at the rope head pressure plate to ensure that there is no misalignment between the position where the steel belt is fixed and the position where it enters the car top; the cable entry guide device 507 and the cable fixing guide device 508 can both be the following structures:

[0083] The guide device may be a single plate, on which a groove matching the shape of the steel strip is provided to provide guidance for the steel strip 506. Alternatively, the guide device may be composed of two plate-like parts, the inner plate having a thickness greater than the steel strip size and having a notch for limiting the left and right positions on the crossbeam, and the outer plate being pressed against the inner plate and fixed.

[0084] The height-reducing cable fixing structure also includes operating instructions, which are used to explain the operating methods of installing, inspecting, and maintaining the device; the inspection device and operating instructions can be set on the cable entry guide device 507;

[0085] After the elevator is installed, a line is drawn on the steel belt 506 and the inspection device 505 at the fixed position corresponding to the steel belt 506. During maintenance, the line can be observed to verify whether the steel belt is in the original position; in a preferred example, the inspection device 505 is a C-shaped plate structure.

[0086] Existing elevators usually use a wire rope end assembly or a steel belt end assembly to fix the wire rope or steel belt to the car top crossbeam. This method requires a height space of more than 250 mm, so the fixing structure will protrude from the car top space. In contrast, the fixing parts (such as the rope end rod 502, the fixing device 503, etc.) involved in the height-reducing cable fixing structure of the present invention are all located inside the car top, greatly reducing the requirements for the top floor height of the elevator shaft.

[0087] In a preferred embodiment, in order to increase the angle at which the steel strip wraps around the round tube cross beam 501, the cross beams can be provided in multiple numbers, preferably two, such as Fig.14 As shown, the steel belt is continuously passed around multiple beams and then fixed.

[0088] The principle of the reduced height cable fixing structure is: according to the Euler formula, after the flexible structure such as the rope body passes around the circular wheel, the maximum tension ratio borne by the two ends satisfies T 1 / T2≤e fα In the formula, T1 and T2 are the larger and smaller pulling forces borne by the two ends of the rope when entering and exiting the circular wheel, f is the equivalent friction coefficient between the rope and the circular wheel, and α is the wrap angle of the rope wrapped around the circular wheel. Fig.13 As shown, in the preferred example where the number of the round tube cross beam 501 is 1, the angle α>270° can be 300°; Fig.14 As shown, in the preferred example where the number of the round tube beams 501 is 2, the angles of α in the left and right round tube beams 501 are α1 and α2 respectively; the angle α1 < 180° can be 150°, the angle α2 greater than 180° can be 190°, and e is the base of the natural logarithm. In the present invention, one end of the steel belt bears the elevator car load T1, and after it is wrapped around the round beam on the car top with a wrap angle α, its tension is attenuated to Therefore, a relatively simple method can be adopted to fix the other end so as to suspend the car. Since the conventional rope end fixing device protrudes from the car top, the requirement for the top height of the hoistway is increased, and the adoption of this device can significantly reduce this requirement.

[0089] Height reduction cable fixing structure 2:

[0090] like Figure 15-18 As shown, the height-reducing rope fixing structure includes a rope head fixing assembly, a movable rope head plate 602, a rope head spring device, and an opposite rope head plate 609; the number of the rope head fixing assemblies is the same as the number of steel strips, the number of the movable rope head plate 602 is 1, and the movable rope head plate 602 includes a flat portion 6021 and a raised portion 6022, the raised portion 6022 is located between the two flat portions 6021, and the flat portion 6021 and the raised portion 6022 are located at different heights. A rope head screw hole is provided on the raised portion 6022, and rope head spring holes are symmetrically provided on the two flat portions 6021.

[0091] The rope head fixing assembly includes a rope head 600, a rope head screw 601, a shock absorbing rubber 603, a rubber end seat 604, a rope head nut 605, a locking nut 606, a cotter pin 607, and a pre-installed nut 608;

[0092] like Fig.15 and Fig.17 As shown, the rope head 600 can be installed in the car roof. At this time, the opposite side rope head plate 609 is fixed on the car roof crossbeam of the elevator, that is, the opposite side rope head plate 609 is the rope head upper plate. Fig.16 and Fig.18 As shown, the rope head 600 is installed in the elevator shaft. At this time, the opposite side rope head plate 609 is fixed on the wall 613, that is, the opposite side rope head plate 609 is a fixed rope head plate.

[0093] One side of the rope head 600 is connected to the steel belt 506 to transfer the load, and the other side is fixedly connected to the rope head screw 601. The end of the rope head screw 601 passes through the pre-installed nut 608, the rope head screw hole on the movable rope head plate 602, the shock-absorbing rubber 603 and the rubber end seat 604 in sequence, and then the rope head nut 605, the locking nut 606 and the cotter pin 607 maintain the end position and prevent loosening.

[0094] The rope end spring device is located between the opposite rope end plate 609 and the flush portion 6021 and is symmetrically arranged, and the number thereof is 2 or an even number. Each rope end spring device includes a rope end spring 610, two spring end seats 611, and a pre-tightening bolt 612, wherein the spring end seat 611 located at the upper portion is provided with a threaded hole, and the spring end seat 611 located at the lower portion is provided with a through hole.

[0095] The rope end spring 610 is sleeved on the spring end seat 611, one end of the rope end spring 610 is fixedly connected to the movable rope end plate 602 through a spring end seat 611, and the other end is fixedly connected to the opposite rope end plate 609 through another spring end seat 611. The pre-tightening bolt 612 passes through the rope end spring hole on the movable rope end plate 602, the spring end seat 611, and the rope end spring 610, and is screwed into the threaded hole of the spring end seat 611 fixed to the opposite rope end plate 609;

[0096] In the present invention, in the horizontal direction, the rope head spring 610 with a relatively large height and other fixed components (including the rope head 600, the rope head screw 601, the shock-absorbing rubber 603, the rubber end seat 604, the rope head nut 605, the locking nut 606, and the cotter pin 607) are arranged in a staggered manner, so that the rope head spring 610 does not occupy the height dimension of the fixed component, thereby reducing the overall height of the fixed structure, and further reducing the requirements for the height of the top floor of the elevator shaft. In addition, the surface of the movable rope head plate used to install the rubber and spring is designed as a stepped structure in the height direction (that is, the height of the flat portion 6021 is different from that of the raised portion 6022), which further reduces the overall height of the fixed structure except the rope head 600. Therefore, except for the rope head 600, other fixed structures can be hidden in the car roof, which greatly improves the aesthetics of the car roof.

[0097] In addition, the design that one end of the rope head spring 610 of the present invention is fixedly connected to the movable rope head plate, and the other end is fixedly connected to the opposite rope head plate 609 fixed to the car top makes the position of the movable rope head plate directly correspond to the compression amount of the rope head spring, and is not affected by the compression amount of the rubber shock-absorbing rubber 603, avoiding the interference of rubber nonlinearity and easy aging, so it can be used to accurately detect the elevator car load. In a preferred example, the pre-installed nuts and pre-tightening bolts of the present invention are used to pre-tighten the rope head fixing assembly, the movable rope head plate 602, the rope head spring device, and the opposite rope head plate 609 in the factory and combine them into an assembly. After the rope head load is installed on site, the pre-tightening force of the pre-installed nuts and pre-tightening bolts disappears naturally without removal.

[0098] In a preferred embodiment, the height-reducing cable fixing structure is also provided with a scale for checking the spring compression amount. A detection device for the position of the movable rope head plate can also be provided to measure the rope head load.

[0099] like Figure 19-20 As shown, the lifting vehicle assembly further includes a main engine base 700 capable of lowering the height of the top floor of the elevator shaft. The main engine base 700 is installed in the top structure of the shaft of the elevator.

[0100] The main engine base 700 is used to carry the elevator main engine 701. The main engine base 700 includes a high portion 702, a connecting portion 703 and a main engine base recess 704. The height of the high portion 702 is higher than the main engine base recess 704. The two ends of the connecting portion 703 are respectively connected to the high portion 702 and the main engine base recess 704.

[0101] The elevator main engine 701 is installed on the top surface of the main engine seat recess 704. The width of the main engine seat 700 is smaller than the width of the elevator main engine 701. The bottom surface of the main engine seat recess 704 is the lowest plane in the hoistway top structure that coincides with the car projection surface.

[0102] like Fig.21 , Fig. 22 As shown, the car top 713 of the elevator includes a car top crossbeam 705, a first side beam 706, a second side beam 707 and a decorative panel 710, and the plane where the upper surface of the beam is located is defined as an upper plane 708, and the plane where the lower surface of the beam is located is defined as a lower plane 709. The car top crossbeam 705 is located in the middle of the first side beam 706 and the second side beam 707, and connects the first side beam 706 and the second side beam 707. The car top crossbeam 705 divides the space between the first side beam 706 and the second side beam 707 into a first space 711 and an electrical device installation space 712; the decorative panel 710 covers the electrical device installation space 712. The bottom area of ​​the main frame recess 704 is smaller than the area of ​​the first space 711. The car top crossbeam 705 can be a round tube, square steel or channel steel beam.

[0103] like Fig.19 As shown, when the elevator car moves upward to the extreme position, the lower plane of the main engine seat recess 704 protrudes into the upper plane of the elevator car top. Specifically, the main engine seat recess 704 protrudes into the first space 711 and can be infinitely close to the lower plane 709.

[0104] The matching relationship between the traditional main engine seat and the elevator car top is: when the elevator car moves upward to the extreme position, the lowest plane in the hoistway top structure that coincides with the car projection plane is misaligned in height with the upper plane 708 of the car top, that is, the height of the bottom surface of the existing main engine seat is always higher than the height of the upper plane 708 of the car top.

[0105] Different from the traditional main engine seat, the bottom surface of the main engine seat recess 704 of the present invention can protrude into the upper plane of the elevator car roof. Therefore, when the elevator car moves upward to the limit position, the bottom surface height of the main engine seat in the present invention is lower than the height of the upper plane 708 of the car roof. Therefore, this design can reduce the minimum top floor height requirement of the elevator. In addition, the width of the top structure of the hoistway sinking into the lower plane of the elevator car roof + the width of the two side beams of the car roof is the minimum limit width of the car. The width of the main engine seat recess 704 is smaller than that of the main engine. Therefore, the main engine seat of the present invention can achieve the minimum limit width of the car.

[0106] like Fig.23 As shown, the present invention also includes a frame front column 300, the frame front column 300 includes a column body 301 and a cover plate 302, the column body 301 and the cover plate 302 cooperate with each other, specifically, the cover plate 302 and the column body 301 are toothed structures that fit together, and form overall strength after combination, more specifically, the column body 301 is provided with a first toothed connection surface 3015, and the cover plate 302 is provided with a second toothed connection surface 3021, and the first toothed connection surface 3015 and the second toothed connection surface 3021 cooperate with each other. After the column body 301 and the cover plate 302 are combined, a wire slot cavity 303 is formed inside.

[0107] The column body 301 includes a first bolt hole guide groove 3011, a second bolt hole guide groove 3012, a third anti-fastener rotation limit groove 3013, a fourth anti-fastener rotation limit groove 3014, a second installation and splicing positioning hole 3017, a third splicing nut strip groove 3018, a third sealing plate or glass installation groove 3019 and a protection plate 30191. A screw protection groove 3016 is formed between the protection plate 30191 and the first toothed connection surface 3015. The protection plate 30191 is located between the screw protection groove 3016 and the wire groove cavity 303.

[0108] The cover plate 302 is provided with a third bolt hole guide groove 3022 and a fourth bolt hole guide groove 3023 .

[0109] The working principle of the front column of the frame is as follows: when the fasteners are fixed by opening holes along the bolt hole guide grooves 3011 and 3012, the bolt heads or nuts located in the column will be restricted in rotation by the anti-fastener rotation limit grooves 3013 and 3014, so no additional holding is required; with the help of the third bolt hole guide groove 3022 and the fourth bolt hole guide groove 3023 cooperating bolts, after the cover plate 302 is fixed to the column body 301, the second toothed connecting surface 3021 on the cover plate 302 and the first toothed connecting surface 3015 on the column body 301 protrude and bite each other, and the screw head protruding from the outside of the cover plate 302 into the column body 301 in the direction of the groove cavity 303 is blocked by the protective plate 30191, thereby protecting the cables in the groove cavity.

[0110] like Figure 1 , Figure 5 As shown in the figure, the front column of the frame is an important structural member of the elevator shaft frame. Especially when the strength of its corner part is insufficient, it will cause the front side of the shaft frame to shift easily and reduce the stability of the shaft frame as a whole. At the same time, the front column of the frame is also the installation basis of the landing door and elevator call device of each floor of the elevator. Multiple cables such as door machine drive cable, door lock safety circuit, elevator call cable, etc. need to be arranged along the front column of the frame and pass through the front column at different positions on each floor to enter the door head of the landing door and the elevator call device.

[0111] Fig.24A frame front column of the prior art is shown, and its corner part is a closed cavity with good structural strength. When the shaft wall panel is an opaque material such as a steel plate, an aluminum-plastic plate, or a wooden board, the above-mentioned cable can be arranged along the inner side of the corner part of the frame front column, and a branch cable can be extended on each floor. The branch cable passes through the through hole on the frame front column and enters the door head and the elevator call device. However, with the development of society, more and more villa owners choose to install elevators at home, and require the elevator to use glass as the shaft wall panel, that is, the elevator shaft is a sightseeing shaft; at this time, if the cable is still installed on the inner side of the corner part of the frame front column, the aesthetics of the product will be greatly reduced; for this reason, it is necessary to pre-install the above-mentioned cable in sections in the closed cavity of each section of the frame front column in the factory during the production of the elevator, and leave joints at the upper and lower ends for connecting with the cables in the upper and lower frame front columns. When installing on site, it is necessary to first connect the cable joints and then connect the frame front column, which is not only cumbersome to install, but also difficult to maintain.

[0112] Compared with the traditional frame front column, the frame front column body 301 of the present invention has an open structure wire trough cavity 303, which is very convenient for cable installation and maintenance; at the same time, after the cable installation is completed and the cover 302 is closed, the cover 302 not only covers the wire trough cavity, but also engages with the column body 301 through the tooth structure, thereby ensuring the structural strength.
