An integrated safety fence

Abstract

This application belongs to the field of safety fence technology, and particularly relates to an integrated safety fence, including multiple support posts and a fence box. The application includes a manual release device and a locking device installed inside the posts. The locking tongue of the protruding support post can cooperate with a baffle or similar device to limit and fix the support post. When the release button on the manual release device is pressed, the release button pulls the first wire core, causing the locking tongue inside the locking device to retract into the locking tongue housing, i.e., the locking tongue protruding from the support post retracts into the support post. Furthermore, when the connecting rod needs to be extended, the connecting rod separates from the support post body, and the connecting rod pulls the locking tongue through the second wire core, causing the locking tongue to retract into the locking device. These two methods ensure that there are no obstructing parts around the support post, allowing the support post to move normally. Moreover, the locking device has both automatic and manual retraction functions, making it convenient to use.

Description

Technical Field

[0001] This application belongs to the field of safety fence technology, and in particular relates to an integrated safety fence. Background Technology

[0002] Currently, existing safety fences use two support posts to support a set of connecting rods, resulting in a large number of support posts being used. In addition, the instability of the support posts and the lack of protection, limiting and support for the support posts and connecting rods when not in use also reduce the lifespan of the support posts and connecting rods. How to fix the support posts within the relevant protective devices is also a problem that needs to be solved. Summary of the Invention

[0003] In order to solve the above problems, this application provides an integrated safety fence.

[0004] The purpose of this application is to provide an integrated safety fence. This application includes a manual release device and a locking device installed inside the column. The locking tongue of the protruding support column can cooperate with a baffle or similar device to limit and fix the support column. When the release button on the manual release device is pressed, the release button pulls the first wire core, causing the locking tongue inside the locking device to retract into the locking tongue housing, i.e., the locking tongue protruding from the support column retracts into the support column. When the connecting rod of this application needs to be extended, the connecting rod separates from the support column body, and the connecting rod pulls the locking tongue through the second wire core, causing the locking tongue to retract into the locking device. These two methods ensure that there are no obstructing parts around the support column, allowing the support column to move normally. Furthermore, the locking device has both automatic and manual retraction functions, making it convenient to use.

[0005] To achieve the purpose of this application, the technical solution of this application is as follows:

[0006] An integrated safety fence includes multiple support posts and a fence box. Each support post between the fence box and the last support post is equipped with an upper steering device and an upper fixing plate connected to the upper steering device. A locking device and a manual release device are installed inside the support post. The manual release device is connected to the locking device. Connecting rods are installed between the column bodies of the support posts and between the support posts and the fence box. Two sets of connecting rods are installed on each support post between the fence box and the last support post. One set of connecting rods is hinged to the upper steering device, and the other set of connecting rods is hinged to the upper fixing plate. A limit cable is installed at the upper end of the connecting rod.

[0007] Furthermore, the locking device is installed inside the column, with the front end of the locking device flush with the outer periphery of the column. The manual release device is connected to the locking device, and the first wire core on the release button of the manual release device is connected to the locking tongue of the locking device. When the release button is pressed, the first wire core pulls the locking tongue into the column. One end of the second wire core is fixed to the connecting rod, and the other end of the second wire core is connected to the locking tongue of the locking device. When the connecting rod moves away from the support column, the second wire core pulls the locking tongue into the column.

[0008] Furthermore, the upper steering device includes a first upper sleeve and a first lower sleeve arranged at intervals. The first upper sleeve is installed above the upper fixed plate, and the first lower sleeve is installed below the upper fixed plate. The first upper sleeve and the first lower sleeve are connected together by an upper connecting plate, such that the distance from the upper end face to the lower end face of the upper fixed plate is less than the distance from the lower end face to the upper end face of the first lower sleeve. A first hinge part is hingedly installed on the upper connecting plate and the upper fixed plate.

[0009] Furthermore, the connecting rod includes several sets of hinged rods that are hinged together. The hinged rods are hinged together via a rotating shaft. Each hinged rod set includes two hinged rods, with the hinge point between the two rods being the middle position of the hinged rods. The rotating shaft includes a threaded post, which is installed in the middle of the hinged rods. A wear-resistant sleeve is installed in the middle of the threaded post, so that the wear-resistant sleeve contacts the hinged rod. Threaded seats are installed at both ends of the threaded post, so that the threaded seats fix the wear-resistant baffles on both sides of the wear-resistant sleeve, and the wear-resistant sleeve is fixed at the center position of the threaded post.

[0010] Furthermore, the integrated safety fence includes a lower steering device, which includes a second upper sleeve and a second lower sleeve arranged at intervals. The lower end of the column has a lower fixing plate. A first through groove is opened on the lower connecting plate, and a second through groove is opened on the lower fixing plate. The second upper sleeve is arranged above the lower fixing plate, and the second lower sleeve is arranged below the lower fixing plate. The second upper sleeve and the second lower sleeve are fixedly connected together through the lower connecting plate, such that the distance from the upper end face of the lower fixing plate to the lower end face is less than the distance from the lower end face of the second upper sleeve to the upper end face of the second lower sleeve. The second hinge part is installed in the first through groove and the second through groove, and the connecting rod is hingedly installed on the second hinge part.

[0011] Furthermore, the first hinge part and the second hinge part include a hinge shaft. First, the hinge shaft of the first hinge part is inserted into the hinge hole of the upper connecting plate and the upper fixed plate. Then, the hinge shaft of the second hinge part is inserted into the first through groove of the lower connecting plate and the second through groove of the lower fixed plate. Then, the connecting rod is hingedly installed on the hinge shaft. Finally, the first stop block and the second stop block are installed at both ends of the hinge shaft.

[0012] Furthermore, a fixing seat is installed on the second stop of the first hinge portion. The hinge shaft, the first stop, and the second stop have coaxial through holes. The fixing seat has a screw hole that connects to the fixing hole on the fixing seat. The limiting cable is installed in the fixing hole, and a screw rod is threaded through the through hole. The screw rod is screwed to the screw hole, and the screw rod squeezes the limiting cable into the fixing seat.

[0013] Furthermore, an adjusting seat is installed on the column. The adjusting seat has a channel and a threaded hole communicating with the channel. The second wire core protruding from the column is passed through the channel, and an adjusting bolt is screwed into the threaded hole. Rotating the adjusting bolt causes the adjusting bolt to press the second wire core, thereby controlling the tension of the second wire core.

[0014] Furthermore, the enclosure box includes an inner limiting rod, with outer limiting rods arranged on both sides of the inner limiting rod. The outer limiting rod has a protrusion on the side facing the inner limiting rod. The distance between the lower end face of the inner limiting rod and the upper end face of the bottom plate is greater than the protrusion. When the support column is arranged inside the enclosure box, the support column is located between the inner limiting rod and the outer limiting rod. The first upper sleeve is arranged between the protrusion and the inner limiting rod.

[0015] Furthermore, a support leg is installed at the lower end of the column. The support leg includes a base, on which two sets of first hinge seats are symmetrically arranged. First hinge rods are hinged to the first hinge seats, such that the first hinge rods on the two sets of first hinge seats are symmetrically arranged about the central axis of the base. A second hinge rod is hinged to the other end of the first hinge rod. The two second hinge rods are hinged to the same rotating rod. A hinge sleeve with a hinged fit is installed at the center of the rotating rod. A connecting seat is arranged at the upper end of the hinge sleeve. The connecting seat is located inside the column and has a clearance fit with the inner circumference of the column. A third through groove is opened on the column. Symmetrically arranged connecting screws are installed on the connecting seat. The connecting screws pass through the groove. Alternatively, a first through slot can be made in the third through slot, an extension rod can be installed at the upper end of the connecting seat, and a pull ring can be installed at the top of the extension rod. A connecting port can be opened on the top cover of the top of the column, the length of which is less than that of the pull ring, so that the extension rod can pass through the opening while the pull ring cannot pass through the connecting port. The extension rod has symmetrically arranged connecting screws, which pass through the first through slot. A third hinge rod can be installed on the second hinge rod. When the support column needs to be erected on the ground, a nut is screwed onto the connecting screw, so that the nut fixes the connecting seat to the column. The third hinge rod is opened, so that the third hinge rod is separated from the second hinge rod, and the second and third hinge rods come into contact with the ground.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] 1. This application includes a manual release device and a locking device installed inside the column. The locking tongue of the protruding support column can cooperate with a baffle or the like to limit and fix the support column. When the release button on the manual release device is pressed, the release button will pull the first wire core to pull the locking tongue inside the locking device into the locking tongue housing, that is, the locking tongue of the protruding support column retracts into the support column. In addition, when the connecting rod of this application needs to be unfolded, the connecting rod will separate from the column body of the support column, and the connecting rod will pull the locking tongue through the second wire core, thereby causing the locking tongue to retract into the locking device. These two methods ensure that there are no obstructing parts on the outer periphery of the support column, thus allowing the support column to move normally. Furthermore, the locking device has automatic and manual retraction functions, making it convenient to use.

[0018] 2. In this application, an adjusting bolt is installed on the adjusting seat. The adjusting bolt contacts the second wire core. By rotating the adjusting bolt, the adjusting bolt presses the second wire core, thereby controlling the tension of the second wire core.

[0019] 3. The locking device of this application includes a locking tongue with an inclined surface. When the locking tongue is engaged with the baffle on the fence box, the inclined surface of the locking tongue will abut against the baffle, thereby compressing the locking tongue spring. When the locking tongue is not engaged with the baffle, the compressed locking tongue spring rebounds, thereby causing the locking tongue to pop out and causing the baffle to block the locking tongue, thereby making the support column with the locking device stably fixed inside the fence box.

[0020] 4. The fence box of this application includes an outer limiting rod and an inner limiting rod. The outer limiting rod and the inner limiting rod form a space to restrict the support column, thereby limiting the support column by the fence box. In addition, the fence box of this application is also provided with a protrusion, and the support column is provided with an upper turning device, so that the sleeve of the upper turning device is located between the protrusion and the inner limiting rod, further fixing the support column inside the fence box.

[0021] 5. The connecting rod of this application is formed by several sets of hinged rods that unfold into an "X" shape. The hinged rod sets form a barrier structure. The limiting cable installed at the upper end of the hinged rod sets can block the upper area of ​​the connecting rods, increasing the difficulty of climbing over the hinged rod sets. In addition, the limiting cable can control the maximum length of the unfolded hinged rod sets. The use of the connecting rope can make the hinged rod sets more stably connected together.

[0022] 6. This application installs an upper steering device and a lower steering device on the support column. Both the upper and lower steering devices rotate through a sleeve installed on the column with a gap. A connecting plate connects the sleeves together. In addition, a fixing plate installed on the column can support the sleeves. The connecting plate cooperates with one set of connecting rods, and the fixing plate cooperates with another set of connecting rods. Thus, one support column can support two sets of connecting rods. Under the action of the steering device, the two sets of connecting rods form an angle to surround the construction area, reducing the use of support columns and the space occupied by the safety fence, and making transportation more convenient.

[0023] 7. This application relies on a base as a support foundation, on which a first hinge rod is installed, a second hinge rod is installed on the first hinge rod, and the same hinge shaft is installed on the second hinge rod, so that the second hinge rod can rotate around the hinge point with the assistance of the first hinge rod, thereby enabling the outrigger to have the function of unfolding and retracting.
