Description

Technical Field

[0001] The utility model relates to the technical field of railings, in particular to a metal railing. Background Art

[0002] Railings were called langan in ancient China, also known as hook railings. They are safety facilities on bridges and buildings. Railings play the role of separation and guidance during use. Well-designed railings are very decorative. In the field of landscaping, metal railings are widely used, which can achieve the role of separation and guidance, making the boundaries of the divided areas clear.

[0003] Road guardrails are safety facilities installed in the middle or on both sides of the road, mainly used to guide traffic, prevent vehicles from turning around at will or pedestrians from crossing the road at will, thereby improving driving safety and ensuring pedestrian safety;

[0004] Existing road railings are usually made of metal and are detachable. However, when the railing is hit, it will disintegrate. This structure can absorb part of the impact force when it is hit, thereby reducing damage to vehicles and passengers. At this time, the disintegrated railing will fly everywhere, posing a certain danger to passers-by.

[0005] To this end, a metal railing is proposed. Summary of the invention

[0006] The utility model aims to provide a metal railing which can solve the problem that when the railing disintegrates and scatters everywhere, it is dangerous to passers-by.

[0007] To achieve the above object, the utility model provides the following technical solution: a metal railing, comprising a base, a horizontal bar and a vertical bar, the base is installed on the ground, the vertical bar is arranged on the base, a sleeve is installed on the vertical bar, and the horizontal bar is movably inserted in the sleeve;

[0008] A cavity is opened on the base, a connecting rope is arranged in the cavity, the connecting rope passes through the vertical rod and the horizontal rod, sponges are arranged in the vertical rod and the horizontal rod, the connecting rope passes through the sponge, and a lubrication mechanism cooperating with the connecting rope is arranged on the sleeve.

[0009] Preferably, the connecting rope is "Y"-shaped and is made of elastic material.

[0010] When installing the handrail, first install the base on the ground, then insert the vertical rods on the base, and then insert the cross rods into the sleeves on the two adjacent vertical rods, so that the cross rods can be fixed.

[0011] Since the vertical bars, horizontal bars and base are all plug-in, when the railing is hit, it will disintegrate. At this time, under the action of the connecting rope of elastic material, the vertical bars and horizontal bars that disintegrate and scatter can be restricted by the connecting rope, thereby reducing the flying range of the horizontal bars and vertical bars, and preventing the flying vertical bars and horizontal bars from hitting pedestrians on the roadside.

[0012] When the railing disintegrates, under the action of the lubrication mechanism, lubricating oil can be applied to the sponge. At this time, the lubricating oil is evenly diffused on the sponge, so that the connecting rope can be evenly lubricated. When the edge of the horizontal bar and the edge of the vertical bar contact the connecting rope, the friction force on the connecting rope can be reduced, and the probability of the connecting rope breaking due to wear is reduced, which ensures that the connecting rope can limit the flying range of the horizontal bar and the vertical bar.

[0013] In addition, the connecting rope made of elastic material can absorb the kinetic energy of the horizontal bar and the vertical bar, thereby reducing the impact force of the horizontal bar and the vertical bar.

[0014] Preferably, the lubrication mechanism comprises an oil box fixedly mounted on the inner top wall of the sleeve, the oil box is filled with lubricating oil, a pressure valve is mounted on the bottom wall of the oil box, and a nozzle is mounted on the output end of the pressure valve.

[0015] Preferably, a pressurizing chamber is provided on the connecting rope, and a conduit with a top end extending into the oil box is inserted on the side wall of the pressurizing chamber, and the conduit is used to provide gas to the oil box.

[0016] During installation, insert the vertical rod into the base 10 cm and the horizontal rod into the sleeve 10 cm. When the vertical rod is out of contact with the base and the horizontal rod is out of contact with the sleeve, the connecting rope is in a stretched state and the connecting rope is squeezed. Therefore, when the vertical rod is out of contact with the base and the horizontal rod is out of contact with the sleeve, the oil box sprays oil outward so that the connecting rope can be lubricated before the vertical rod is out of contact with the base and the horizontal rod is out of contact with the sleeve.

[0017] The pressure valve can prevent the lubricating oil in the oil box from dripping naturally, and the spray head can expand the oil spray range to improve the lubrication effect on the sponge and the connecting rope.

[0018] Preferably, heat conducting rods are evenly inserted on the bottom wall of the cavity, and the bottom ends of the heat conducting rods extend outside the base.

[0019] Since the base covers the ground and the heat-conducting rod is arranged on the bottom wall of the base, it can prevent direct sunlight. Under the action of heat exchange, the heat-conducting rod can cool down the oil box to prevent the pressure in the oil box from increasing due to excessive temperature in summer, so that the lubricating oil is automatically discharged, which ensures that the lubricating oil can lubricate the connecting rope in time.

[0020] Preferably, a plug hole is provided on the base, an elastic member is provided in the plug hole, a spoiler cavity is provided on the elastic member, and air holes are provided on the side wall of the spoiler cavity.

[0021] When a vehicle passes by, the ground vibrates, and the elastic part causes the vertical rod to shake. During the shaking of the vertical rod, the elastic part is intermittently squeezed and restored, thereby driving the gas flow in the cavity through the spoiler cavity and the air holes, increasing the contact probability between the low-temperature gas and the oil box, and improving the cooling effect on the oil box.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] By providing a connecting rope, a sponge, and an oil box, the present application can absorb the kinetic energy of the vertical rod and the horizontal rod through the connecting rope made of elastic material when the railing disintegrates, limit the range of the vertical rod and the horizontal rod flying, prevent parts from flying onto the sidewalk, and improve safety.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figures 1 to 4 , the utility model provides a technical solution:

[0033] A metal railing, comprising a base 1, a crossbar 2 and a vertical bar 3, wherein the base 1 is installed on the ground, the vertical bar 3 is arranged on the base 1, a sleeve 4 is installed on the vertical bar 3, and the crossbar 2 is movably inserted in the sleeve 4;

[0034] A cavity 5 is provided on the base 1 , a connecting rope 6 is provided in the cavity 5 , the connecting rope 6 passes through the vertical rod 3 and the horizontal rod 2 , sponges 7 are provided in both the vertical rod 3 and the horizontal rod 2 , the connecting rope 6 passes through the sponge 7 , and a lubrication mechanism cooperating with the connecting rope 6 is provided on the sleeve 4 .

[0035] The connecting rope 6 is "Y"-shaped and is made of elastic material.

[0036] When installing the handrail, firstly install the base 1 on the ground, then insert the vertical rods 3 on the base 1, and then insert the cross rods 2 into the sleeves 4 on two adjacent vertical rods 3, so that the cross rods 2 can be fixed.

[0037] Since the vertical rod 3, the horizontal rod 2 and the base 1 are all plugged in, when the railing is hit, the railing will disintegrate. At this time, under the action of the connecting rope 6 made of elastic material, the vertical rod 3 and the horizontal rod 2 that are disintegrated and scattered can be restricted by the connecting rope 6, thereby reducing the flying range of the horizontal rod 2 and the vertical rod 3, and preventing the flying vertical rod 3 and the horizontal rod 2 from hitting pedestrians on the roadside.

[0038] When the railing is dismantled, under the action of the lubrication mechanism, the lubricating oil 9 can be applied to the sponge 7. At this time, the lubricating oil 9 is evenly diffused on the sponge 7, so that the connecting rope 6 can be evenly lubricated. When the edge of the horizontal bar 2 and the edge of the vertical bar 3 contact the connecting rope 6, the friction force on the connecting rope 6 can be reduced, and the probability of the connecting rope 6 breaking due to wear is reduced, which ensures that the connecting rope 6 can limit the flying range of the horizontal bar 2 and the vertical bar 3.

[0039] Furthermore, the connecting rope 6 made of elastic material can absorb the kinetic energy of the horizontal rod 2 and the vertical rod 3 , thereby reducing the impact force of the horizontal rod 2 and the vertical rod 3 .

[0040] Specifically, Figure 2As shown, the lubrication mechanism includes an oil box 8 fixedly mounted on the inner top wall of the sleeve 4, the oil box 8 is filled with lubricating oil 9, a pressure valve 10 is mounted on the bottom wall of the oil box 8, and a nozzle 11 is mounted on the output end of the pressure valve 10.

[0041] The connecting rope 6 is provided with a pressurizing chamber 12 , and a conduit 13 with a top end extending into the oil box 8 is inserted into the side wall of the pressurizing chamber 12 . The conduit 13 is used to provide gas to the oil box 8 .

[0042] During installation, the vertical rod 3 is inserted into the base 1 by 10 cm, and the horizontal rod 2 is inserted into the sleeve 4 by 10 cm. When the vertical rod 3 is out of contact with the base 1 and the horizontal rod 2 is out of contact with the sleeve 4, the connecting rope 6 is in a stretched state. At this time, the connecting rope 6 is squeezed. Therefore, when the vertical rod 3 is out of contact with the base 1 and the horizontal rod 2 is out of contact with the sleeve 4, the oil box 8 sprays oil outward so that the connecting rope 6 can be lubricated before the vertical rod 3 is out of contact with the base 1 and the horizontal rod 2 is out of contact with the sleeve 4.

[0043] The pressure valve 10 can prevent the lubricating oil 9 in the oil box 8 from dripping naturally, and the spray head 11 can expand the oil spraying range to improve the lubricating effect on the sponge 7 and the connecting rope 6.

[0044] Specifically, Figure 2 As shown, heat conducting rods 14 are evenly inserted on the bottom wall of the cavity 5 , and the bottom ends of the heat conducting rods 14 extend outside the base 1 .

[0045] Since the base 1 covers the ground and the heat-conducting rod 14 is arranged on the bottom wall of the base 1, it can prevent direct sunlight. Under the effect of heat exchange, the heat-conducting rod 14 can cool down the oil box 8 to prevent the pressure in the oil box 8 from increasing due to excessive temperature in summer, so that the lubricating oil 9 is automatically discharged, which ensures that the lubricating oil 9 can lubricate the connecting rope 6 in time.

[0046] Specifically, Figure 2 As shown, the base 1 is provided with an insertion hole, an elastic member 15 is arranged in the insertion hole, a spoiler cavity 16 is arranged on the elastic member 15 , and an air hole 17 is arranged on the side wall of the spoiler cavity 16 .

[0047] When a vehicle passes by, the ground vibrates, and the elastic member 15 causes the vertical rod 3 to shake. During the shaking of the vertical rod 3, the elastic member 15 is intermittently squeezed and restored, thereby driving the gas flow in the cavity 5 through the spoiler cavity 16 and the air hole 17, thereby increasing the contact probability between the low-temperature gas and the oil box 8 and improving the cooling effect on the oil box 8.

[0048] Working principle: When installing the handrail, first install the base 1 on the ground, then insert the vertical rod 3 on the base 1, and then insert the cross bar 2 into the sleeve 4 on the two adjacent vertical rods 3, so that the cross bar 2 can be fixed.

[0049] Since the vertical rod 3, the horizontal rod 2 and the base 1 are all plugged in, when the railing is hit, the railing will disintegrate. At this time, under the action of the connecting rope 6 made of elastic material, the vertical rod 3 and the horizontal rod 2 that are disintegrated and scattered can be restricted by the connecting rope 6, thereby reducing the flying range of the horizontal rod 2 and the vertical rod 3, and preventing the flying vertical rod 3 and the horizontal rod 2 from hitting pedestrians on the roadside.

[0050] When the railing is dismantled, under the action of the lubrication mechanism, the lubricating oil 9 can be applied to the sponge 7. At this time, the lubricating oil 9 is evenly diffused on the sponge 7, so that the connecting rope 6 can be evenly lubricated. When the edge of the horizontal bar 2 and the edge of the vertical bar 3 contact the connecting rope 6, the friction force on the connecting rope 6 can be reduced, and the probability of the connecting rope 6 breaking due to wear is reduced, which ensures that the connecting rope 6 can limit the flying range of the horizontal bar 2 and the vertical bar 3.

[0051] In addition, the elastic connecting rope 6 can absorb the kinetic energy of the horizontal rod 2 and the vertical rod 3, thereby reducing the impact force of the horizontal rod 2 and the vertical rod 3. During installation, the vertical rod 3 is inserted into the base 1 by 10 cm, and the horizontal rod 2 is inserted into the sleeve 4 by 10 cm. During the process of the vertical rod 3 and the base 1 being disconnected, and the horizontal rod 2 and the sleeve 4 being disconnected, the connecting rope 6 is in a stretched state, and the connecting rope 6 is squeezed at this time. Therefore, when the vertical rod 3 and the base 1 are disconnected, and the horizontal rod 2 and the sleeve 4 are disconnected, the oil box 8 sprays oil outwards, so that the connecting rope 6 can be lubricated before the vertical rod 3 and the base 1 are disconnected, and before the horizontal rod 2 and the sleeve 4 are disconnected.

[0052] The pressure valve 10 can prevent the lubricating oil 9 in the oil box 8 from dripping naturally, and the spray head 11 can expand the oil spraying range to improve the lubricating effect on the sponge 7 and the connecting rope 6.

[0053] Since the base 1 covers the ground and the heat-conducting rod 14 is arranged on the bottom wall of the base 1, it can prevent direct sunlight. Under the effect of heat exchange, the heat-conducting rod 14 can cool down the oil box 8 to prevent the pressure in the oil box 8 from increasing due to excessive temperature in summer, so that the lubricating oil 9 is automatically discharged, which ensures that the lubricating oil 9 can lubricate the connecting rope 6 in time.

[0054] When a vehicle passes by, the ground vibrates, and the elastic member 15 causes the vertical rod 3 to shake. During the shaking of the vertical rod 3, the elastic member 15 is intermittently squeezed and restored, thereby driving the gas flow in the cavity 5 through the spoiler cavity 16 and the air hole 17, thereby increasing the contact probability between the low-temperature gas and the oil box 8 and improving the cooling effect on the oil box 8.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
