Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of guardrails, more particularly, relates to a guardrail structure capable of being quickly assembled. BACKGROUND

[0002] Guardrails are widely used in various places, such as construction sites, road isolation, residential areas, commercial areas, and industrial production areas. Guardrails mainly serve the purpose of separation, protection, and warning, effectively ensuring the safety of personnel and goods and preventing accidents.

[0003] Based on the understanding of the application of existing guardrail structures, the following situations exist:

[0004] In the assembly process of existing guardrails, complex tools and cumbersome operation steps are often required, such as welding and tightening a large number of bolts and nuts. This not only consumes a lot of time and labor, but also requires high professional skills of the installers, resulting in low installation efficiency of the guardrails, which cannot meet the needs of some scenarios that require quick setup of protective facilities.

[0005] The fixing method of traditional guardrails often lacks sufficient flexibility and adjustability. When facing guardrail bodies of different thicknesses and sizes, it is difficult to achieve quick and stable fixation, and it cannot well adapt to diversified protection needs. Moreover, during the use of the guardrail, if some parts need to be replaced due to damage, the process of disassembling and installing new parts is difficult due to the limitation of the connection structure, increasing the maintenance cost and time cost. UTILITY MODEL CONTENTS

[0007] The utility model adopts the technical scheme of:

[0008] The utility model provides a kind of quickly assembled guardrail structure, including adapter frame;The top middle position of the adapter frame is fixedly installed with positioning plate, the inside middle position of positioning plate is opened with through hole, and the inside middle position of positioning plate is rotatably connected with screw piece in through hole, the thread of the front and rear ends of screw piece is reversely designed, the rear end of screw piece is provided with handle, the top rear end of adapter frame is rotatably connected with locking bolt, the bottom position of locking bolt is attached with the middle rear position of screw piece, and the top front and rear ends of adapter frame are slidably connected with one clamping frame respectively.

[0009] According to an embodiment of the utility model, the two clamping frames are symmetrically designed, and screw holes are formed in the middle lower positions of the two clamping frames.

[0010] According to an embodiment of the utility model, the inside positions of each clamping frame are provided with clamping grooves, and screw holes are formed in the middle positions of the top of each clamping frame.

[0011] According to an embodiment of the utility model, an adjusting bolt is rotatably connected in each screw hole of each clamping frame, the bottom position of each adjusting bolt is rotatably connected with the middle position of the top of a clamping plate, and the two adjusting bolts are slidably connected in the clamping groove of one clamping frame.

[0012] According to an embodiment of the utility model, the adapter frame is located below the guardrail main body, and the bottom position of the guardrail main body is located inside the grooves of the two clamping frames.

[0013] According to an embodiment of the utility model, mounting grooves are arranged in the middle positions of the left and right sides of the guardrail main body, and the mounting grooves at both ends of the guardrail main body are symmetrically designed.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] By combining the thread connection of the screw piece and the clamping frame and the ingenious design of the reverse threads at the front and rear ends of the screw piece, rotating the handle at the rear end of the screw piece can make the two clamping frames slide towards each other or in opposite directions simultaneously, realizing the quick clamping and loosening of the guardrail main body, without the need for complex tools, greatly shortening the assembly and disassembly time of the guardrail, improving work efficiency, and being particularly suitable for scenes where the guardrail needs to be quickly built and removed.

[0016] The adjusting bolt and the clamping plate arranged on each clamping frame can be flexibly adjusted in height by rotating the adjusting bolt according to the different thicknesses of the guardrail main body, so that the clamping plate closely adheres to the surface of the guardrail main body, ensuring that the guardrail main body is firmly fixed, and being able to adapt to guardrail main bodies of various specifications and meet various protection needs.

[0017] The locking bolt is rotationally connected to the rear upper position of the adapter frame, and after the guardrail body is clamped, the locking bolt is rotated to make the bottom thereof abut against the rear position of the screw rod piece, thereby effectively locking the screw rod piece and preventing the screw rod piece from rotating due to external force and other factors in use, so as to ensure the stability of the connection between the clamping frame and the guardrail body, ensure the safety and reliability of the guardrail, and reduce the security risks even in the case of external impact or long-term use.

[0018] Due to the adoption of the detachable connection structure, when the guardrail body or other components are damaged, the damaged components can be quickly detached and replaced by reversely rotating the screw rod piece, without the need to disassemble the entire guardrail, thereby reducing the maintenance cost and time cost.
