The mounting seat 110 is provided with a vertical mounting surface, can be attached to and connected with a wall surface, and realizes street-code horizontal mounting. The mount 110 is fixed to the wall body by bolts. The mount 110 is provided at both ends thereof to extend in a lateral direction. The mounting base 110 may have an L shape when viewed in the front-rear direction, or both ends of the mounting base 110 may extend in the lateral direction.

The two ends of the vertical rod 120 extend along the up-down direction, and the lower end of the vertical rod 120 is fixedly connected with the upper surface of the mounting seat 110, for example, by welding or bolting. The number of the vertical rods 120 is two, and the two vertical rods 120 are arranged at a certain interval along the transverse direction.

In this embodiment, the lateral direction is the left-right direction, the vertical direction is the up-down direction, and the longitudinal direction is the front-back direction. The vertical bar 120 may be a square bar. The left side of the mounting base 110 is a vertical mounting surface, and can be fixed on a wall surface or a telegraph pole by bolts.

The two ends of the cross bar 200 extend in the left-right direction, the left end of the cross bar 200 is slidably connected with the left vertical bar 120 up and down, and the right end of the cross bar 200 is slidably connected with the right vertical bar 120 up and down, so that the cross bar 200 can slide up or down relative to the vertical bar 120. The number of the crossbars 200 is at least two, and all the crossbars 200 are spaced apart in the up-down direction.

It will be appreciated that the height distance between two crossbars 200 adjacent one another can be adjusted. The number of the cross bars 200 may be two, three or more, which is not limited herein.

The insulator 300 is sleeved on the cross bar 200, and the central axis of the insulator 300 extends in the left-right direction, so that the cable 800 can be installed on the street sign indicating number in the front-rear direction. It will be appreciated that the insulator 300 may be rotatable about an axis extending in the lateral direction relative to the rail 200 or may be stationary relative to the rail 200, as not limited herein.

The supporting member 700 is disposed between two upper and lower adjacent crossbars 200, the lower surface of the supporting member 700 can be abutted against the lower crossbar 200, and the upper surface of the supporting member 700 can be abutted against the upper crossbar 200. The left and right ends of the cross bar 200 are provided with the supporting members 700, so that the left and right ends of the cross bar 200 can be well supported.

It will be appreciated that since the support 700 is provided, the height interval between the upper and lower adjacent two crossbars 200 has a minimum value, at this time, the upper and lower opposite two insulators 300 have a certain height interval with respect to the upper and lower adjacent two crossbars 200 without contact with each other, and the upper and lower opposite two insulators 300 are commonly formed with the clamping holes 510, and the clamping holes 510 can be used to fix the low voltage cable 800. Specifically, each of the clamping holes 510 is defined by annular wire-laying grooves of each two of the insulators 300 adjacent to each other up and down.

It will be appreciated that in the case where the number of the cross bars 200 is three and one insulator 300 is provided on each cross bar 200, two low voltage cables 800 may be installed in the up-down direction, wherein the lower portion of the annular wire-placing slot can apply a downward pressing action to the low voltage cable 800 below the insulator 300 with the insulator 300 positioned in the middle, and the upper portion of the annular wire-placing slot can apply a supporting action to the low voltage cable 800 above the insulator 300, thereby fully utilizing the annular wire-placing slot of the insulator 300.

If the number of the cross bars 200 is four, three voltage cables 800 may be installed in the up-down direction; if the number of the crossbars 200 is six, five voltage cables 800 may be installed in the up-down direction. Therefore, only one cross rod 200 and the insulators 300 thereon are needed to be added, and a wire clamp is not needed to be configured for each insulator 300, so that the low-voltage cable 800 can be effectively fixed, the overall weight of the street code is effectively reduced, and the phenomenon that the street code is too heavy to cause wall or telegraph pole damage or street code falling easily is avoided.

In some embodiments, the number of insulators 300 per crossbar 200 is one.

In other embodiments, the number of insulators 300 per crossbar 200 is multiple, such as two, three, or more, without limitation. If the number of insulators 300 on each cross bar 200 is four, four cables 800 may be laid in the left-right direction. So configured, the number of low voltage cables 800 that can be installed per crossbar 200 is increased.

In addition, the wall surface of the annular wire placing groove of the insulator 300 can be provided with protruding points, so that acting force between the insulator 300 and the low-voltage cable 800 can be enhanced, and the clamping effect of the insulator 300 on the low-voltage cable 800 is enhanced.

A locking member 400 is provided on the mounting assembly 100, the locking member 400 being capable of being detachably connected to the uppermost rail 200.

It will be appreciated that the crossbar 200 naturally presses down on the low-voltage cable 800 due to the gravity, however, there is a possibility that the crossbar 200 moves up relative to the mounting assembly 100 due to the external force, so that the low-voltage cable 800 on the street yard cannot be firmly fixed.

Therefore, by providing the locking member 400, a downward force is applied to the uppermost cross bar 200, so as to limit the upward movement of the uppermost cross bar 200, and then the lower cross bar 200 cannot move upward, so that the positions of all the cross bars 200 are fixed, the low-voltage cable 800 is tightly clamped by two insulators 300 adjacent to each other up and down, and the fixing effect of the street yard on the low-voltage cable 800 is promoted.

In the street code for installing a low-voltage cable provided in this embodiment, since the plurality of cross bars 200 provided with the insulators 300 are arranged along the up-down direction and slidingly connected with the two vertical bars 120 on the installation component 100, each cross bar 200 can slide up and down relative to the vertical bar 120; after the low-voltage cable 800 is placed in the clamping hole 510 between the upper and lower adjacent insulators 300, the upper and lower adjacent support rods are driven to approach each other, so that the low-voltage cable 800 is tightly clamped, the annular wire placing grooves of the insulators 300 are fully utilized, wire clamps can be saved, the whole weight of the street code is reduced, and the working efficiency is improved.

Moreover, the supporting piece 700 is arranged between the upper and lower adjacent cross bars 200, so that the gravity of the cross bars 200, the insulators 300 and the low-voltage cables above the supporting piece 700 is effectively dispersed, the low-voltage cables 800 below the supporting piece 700 are effectively prevented from being damaged easily due to overlarge stress, and the low-voltage cables 800 on the street yard are well protected.

By providing the locking member 400, the uppermost cross bar 200 is locked, so that the fixing effect on the low voltage cable is prevented from being weakened due to the upward movement of the cross bar 200 under the action of external force.

In some embodiments, the support 700 is pluggable to achieve its connection to the crossbar 200.

Specifically, each of the crossbars 200 is provided with a connection hole 211, the axis of the connection hole 211 extends in the up-down direction, and the connection hole 211 penetrates the upper and lower surfaces of the crossbar 200. The left and right ends of each cross bar 200 are provided with connection holes 211. The two ends of the supporting member 700 extend in the up-down direction, the upper end of the supporting member 700 is provided with a connecting portion 710, the lower end of the supporting member 700 is also provided with a connecting portion 710, in addition, the supporting member 700 is also provided with a limiting portion 720, the limiting portion 720 is located between the upper and lower connecting portions 710, and the outer diameter of the limiting portion 720 is larger than the outer diameters of the two connecting portions 710.

The shape and size of the connection portion 710 are adapted to the connection hole 211. For example, if the connecting hole 211 is a circular hole, the connecting portion 710 is a cylinder; the connection hole 211 is a square hole, and the connection portion 710 is a quadrangular prism. The stopper 720 may have a square or circular shape in a plan view, and is not limited thereto.

In the mounting work of the support 700, the connection portion 710 may be inserted into the connection hole 211 of the cross bar 200 and connected to the inner circumferential wall surface of the connection hole 211. After the upper and lower connection portions 710 of the support 700 are respectively abutted with the connection holes 211 of the upper and lower cross bars 200, the limit portion 720 is located between the upper and lower adjacent cross bars 200, and the lower surface of the limit portion 720 is abutted with the upper surface of the lower cross bar 200, and the upper surface of the limit portion 720 is abutted with the lower surface of the upper cross bar 200.

It can be appreciated that when the upper and lower adjacent insulators 300 clamp the cable 800, the connection portion 710 at the lower end of the support member 700 may be inserted into the connection hole 211 of the lower cross bar 200 downward to pre-mount the support member 700, and then the connection hole 211 of the upper cross bar 200 is correspondingly sleeved on the connection portion 710 at the upper end of the support member 700, so that the difficulty in mounting the support member 700 between the upper and lower adjacent cross bars 200 is reduced, and the limit portion 720 of the support member 700 can exert a sufficient supporting effect on the upper cross bar 200.

Since the thickness (i.e., the dimension in the up-down direction) of the stopper 720 of the supporter 700 defines the minimum distance between the upper and lower adjacent insulators 300. Then, the worker can replace different supporting members 700 according to the actual diameter of the low voltage cable 800, so that two insulators 300 adjacent to each other can tightly clamp the low voltage cable 800, thereby preventing the low voltage cable 800 from being displaced, and the low voltage cable 800 can be prevented from being crushed under the supporting action of the supporting members 700.

Further, the limiting portion 720 is a connecting nut, and one of the connecting portions 710 on the supporting member 700 is provided with external threads, so that the limiting portion 720 can be in threaded connection with one of the connecting portions 710, and the limiting portion 720 is detachable. Then, the worker can replace the limiting part 720 with a different thickness, thereby adjusting the interval between the two insulators 300 adjacent to each other, so as to be suitable for the installation work of the low voltage cable 800 with different diameters, without replacing the whole support 700.

It can be appreciated that if the connecting portion 710 above the supporting member 700 is provided with external threads, an abutment portion may be provided between the upper and lower connecting portions 710, and after the limiting portion 720 is screwed in place, the abutment portion may be contacted, so as to further limit the screwing distance of the limiting portion 720. Of course, if the external thread is provided on the connection portion 710 above the support 700, the outer diameter of the connection portion 710 may be smaller than the outer diameter of the connection portion 710 below the support 700, and thus the connection portion 710 may not be separated from the connection portion 710 below during the downward screwing of the limiting portion 720. If one of the connection portions 710 of the support 700 is provided with external threads, the connection hole 211 is provided as a circular hole having a smooth wall surface.

In some embodiments, one support 700 is provided at each of the left and right ends of the crossbar 200.

In other embodiments, the number of the supporting members 700 is plural, specifically, three, four or more, and all the supporting members 700 are arranged at intervals in the lateral direction. By increasing the plurality of supporting members 700 to increase the contact area between the supporting members 700 and the cross bar 200, the cross bar 200 above the supporting members can be effectively supported, and the gravity of the cross bar 200, the insulator 300 and the low-voltage cable above the supporting members 700 can be further dispersed, so that the situation that the low-voltage cable 800 is crushed is avoided.

In addition, since the cross bar 200 can be detached from the installation component 100, the cross bar 200 is provided with the connection hole 211, so that in order to be more convenient for the construction of the staff, the installation seat 110 can be provided with the hook or the inclined rod, the connection hole 211 of the cross bar 200 can pass through the hook or the inclined rod and obtain the supporting function of the hook or the inclined rod, so that the cross bar 200 can be temporarily stored on the hook or the inclined rod, and the staff can place the plurality of cross bars 200 on the installation component 100 one by one without hanging the cross bars 200 on the body or placing the cross bars on the ground when installing the plurality of low-voltage cables 800 which are arranged up and down. If hooks are used, the hooks may be provided on the lower surface of the mounting base 110.

In some embodiments, the mounting assembly 100 is provided with a clamping block 600, the clamping block 600 is fixedly connected with the mounting seat 110, the clamping block 600 is arranged below the lowest cross bar 200, and the upper surface of the clamping block 600 is provided with an arc-shaped groove. The clamp block 600 is made of an insulating material such as plastic or ceramic, and avoids the problem of short circuit and leakage caused by damage to the outer skin of the low voltage cable 800. Then, the clamp block 600 may be formed with a limiting hole 520 together with the insulator 300 on the lowermost cross bar 200, and the limiting hole 520 can be used to fix the low voltage cable 800.

So set up, can utilize clamp splice 600 to cooperate with insulator 300 below, carry out effective centre gripping to low voltage cable 800, so alright increase the mountable low voltage cable 800 quantity on the street sign indicating number. Then, in the case where only one insulator 300 is provided per cross bar 200, the number of cross bars 200 is consistent with the number of installation of the low voltage cables 800.

Further, the clamp block 600 is detachably connected to the mounting assembly 100 to facilitate the removal and replacement of the clamp block 600 from the mounting assembly 100. In this embodiment, the clamp block 600 is secured to the mounting assembly 100 by bolts. Of course, it is not precluded that the clamp block 600 be mounted to the mounting assembly 100 using a snap-fit connection.

In some embodiments, each of the vertical rods 120 is provided with a clamping groove 121, specifically, the clamping groove 121 penetrates through the upper surface of the vertical rod 120, and the clamping groove 121 is provided on the side surface of the two vertical rods 120, which are close to each other. The card slot 121 may have a square shape or a T shape in a plan view, which is not limited herein.

In the present embodiment, a clamping groove 121 is concavely formed on the right side surface of the vertical rod 120 located on the left side, and a clamping groove 121 is concavely formed on the left side surface of the vertical rod 120 located on the right side. The draw-in groove 121 is square, and the left end and the right-hand member of horizontal pole 200 all are provided with slider 210, and slider 210 is the square form, can with draw-in groove 121 looks adaptation, so can increase slider 210 and support piece 700's area of contact, be favorable to alleviateing the pressure of low voltage cable 800. The sliding block 210 and the cross bar 200 may be connected by bolting or welding. The coupling hole 211 is provided at the slider 210.

Then, the worker may install each cross bar 200 on the installation assembly 100 from top to bottom, so that the sliding blocks 210 at the left and right ends of each cross bar 200 are respectively inserted into the clamping grooves 121 at the left and right sides, and the sliding blocks 210 at the left and right ends of the cross bar 200 are connected with the inner wall surfaces of the clamping grooves 121, so that the cross bar 200 can stably move upwards or downwards.

Because each rail 200 is removable from the mounting assembly 100, a worker can quickly place the portion of the cable 800 that is desired to be clamped directly onto the insulator 300 on the rail 200.

If the clamping groove 121 does not penetrate the upper surface of the vertical rod 120, the worker cannot detach each of the cross rods 200 from the mounting assembly 100, and the worker needs to pass the free end of the low voltage cable 800 through the area between the two insulators 300 adjacent to each other.
