Description

Technical Field

[0001] The utility model relates to the technical field of highway engineering, in particular to a protective device. Background Art

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. During the construction of highway projects, isolation and protection devices are generally required on the periphery to protect the location under construction, so that non-staff cannot easily enter the area.

[0003] In the prior art, there is a safety protection device for highway engineering construction with patent number CN217106446U, which includes a base plate, a plurality of first guardrails equidistantly distributed on the top of the base plate and arranged vertically, and a first fixed plate is fixedly connected to the bottom of the first guardrail and arranged horizontally. By setting a rotating groove, one end of the second rotating rod rotates in the rotating groove, thereby improving the rotation effect of the second rotating rod, improving work efficiency, and increasing practicality. However, the existing safety protection device for highway engineering construction has the problem of not being able to increase the contact area with the ground when it is used, so that the existing safety protection device for highway engineering construction is unstable when in use and is prone to tipping over. Therefore, a protection device is proposed. Utility Model Content

[0004] In view of this, the embodiment of the utility model hopes to provide a protective device to solve or alleviate the technical problems existing in the prior art. By installing a second telescopic component, the contact area between the device and the ground can be increased after the second telescopic component is extended and retracted. Because the contact area between the device and the ground is increased, the device is more stable during use and is not prone to tipping over.

[0005] The technical solution of the utility model embodiment is achieved as follows:

[0006] A protective device comprises a base plate, two rotating components are rotatably arranged on both sides of the base plate, the rotating components comprise a rotating plate, a first telescopic component rotatably arranged at one end of the rotating plate, and two second telescopic components, the first telescopic component comprises a rotating shell, a plurality of threaded tubes threadedly arranged in sequence, a first fixed block is fixedly installed on the top of each threaded tube, a fixing strip is detachably fixedly connected between the two first fixed blocks, the second telescopic component comprises two first shells and a second shell fixed to each other, a telescopic square rod slidably arranged in the first shell and the second shell, a first spring is fixedly installed between the telescopic square rod and the first shell, a second fixed block is fixedly installed on one end of the telescopic square rod, and a fixing plate is fixedly installed on one side of the two rotating components.

[0007] Preferably: the two ends of the base plate are respectively rotatably cooperated with the sides where the two rotating components are close to each other, and the two first telescopic components are located on the sides where the two rotating components are far away from each other. The first telescopic components can be folded after being installed, so that the volume of the device is smaller after the first telescopic components are folded, which makes it easier to move and transport the device.

[0008] Preferably: two limit latches are provided for sliding cooperation at the bottom of the two rotating plates, and a second spring is fixedly installed between the two limit latches and the two rotating plates. When the first telescopic component is folded to the lower side of the rotating plate, the limit latch is pulled open at this time, and the first telescopic component is folded into the upper side of the limit latch. At this time, the force pulling the limit latch is released, and the limit latch slides under the drive of the second spring. After the limit latch slides, the first telescopic component is limited, so that the first telescopic component is not easy to unfold again after being folded.

[0009] Preferably: the two second telescopic components are located on both sides of the first telescopic component, and the bottoms of multiple threaded tubes that are threadedly arranged in sequence are fixedly installed inside the rotating shell. The installation of the second telescopic component can increase the supporting area of ​​the device, thereby making the device more stable when used.

[0010] Preferably: four sliding protrusions are arranged on the circumferential side of the telescopic square rod, a guide hole corresponding to the telescopic square rod is opened on one side of the second shell, the second fixed block is located on the side away from the first shell, and a torsion spring is fixedly installed between the first shell and the rotating plate. The installation of the torsion spring can push the second telescopic assembly, thereby facilitating the support of the device after the second telescopic assembly is unfolded.

[0011] Preferably: a through hole is provided on the fixing plate for accommodating one end of the telescopic square rod, and the two fixing plates are located on a side close to the base plate. The through hole is provided so that after the telescopic square rod rotates into the through hole, it is not easy to unfold again, affecting the folding of the device.

[0012] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0013] 1. The utility model can increase the contact area between the device and the ground after the second telescopic component is extended and retracted by installing the second telescopic component. Because the contact area between the device and the ground is increased, the device is more stable during use and is not prone to tipping over.

[0014] 2. The utility model installs the first telescopic component so that the device can be contracted. Because the device can be contracted, the first telescopic component makes the device smaller after contraction. Because the device is smaller after contraction, the device is easier to carry and transport.

DETAILED DESCRIPTION

[0023] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, an embodiment of the utility model provides a protective device, including: a base plate 1, two rotating components 2 are rotatably provided on both sides of the base plate 1, the rotating component 2 includes a rotating plate 3, a first telescopic component 4 rotatably provided at one end of the rotating plate 3, and two second telescopic components 5, the first telescopic component 4 includes a rotating shell 6, a plurality of threaded tubes 7 threadedly provided in sequence, a first fixed block 8 is fixedly installed on the top of each threaded tube 7, a fixing strip 9 is detachably fixedly connected between the two first fixed blocks 8, the second telescopic component 5 includes two first shells 10 and a second shell 11 fixed to each other, a telescopic square rod 12 slidably provided in the first shell 10 and the second shell 11, a first spring 13 fixedly provided between the telescopic square rod 12 and the first shell 10, a second fixed block 14 is fixedly provided at one end of the telescopic square rod 12, and a fixing plate 15 is fixedly provided on one side of the two rotating components 2.

[0026] In this embodiment, specifically: the two ends of the base plate 1 are respectively rotatably matched with the sides of the two rotating components 2 that are close to each other, and the two first telescopic components 4 are located on the sides of the two rotating components 2 that are away from each other. The installation of the rotating components 2 facilitates the folding of the device.

[0027] In the present embodiment, specifically: two limit pins 16 are provided for sliding cooperation at the bottom of the two rotating plates 3, and a second spring 17 is fixedly installed between the two limit pins 16 and the two rotating plates 3. The installation of the limit pins 16 can limit the first telescopic component 4 after folding, so that the first telescopic component 4 is not easy to unfold again after being limited, thereby affecting the transportation of the device.

[0028] In this embodiment, specifically: the two second telescopic components 5 are located on both sides of the first telescopic component 4, and the bottoms of the multiple threaded tubes 7 that are threadedly arranged in sequence are fixedly installed inside the rotating shell 6. When the multiple threaded tubes 7 need to be telescoped, one of the threaded tubes 7 is rotated at this time, so that the threaded tube 7 rises, and then the fixing bar 9 is fixed on the first fixing block 8, so that the fixed fixing bar 9 can play a certain protective role.

[0029] In this embodiment, specifically: four sliding protrusions are arranged on the circumferential side of the telescopic square rod 12, a guide hole corresponding to the telescopic square rod 12 is opened on one side of the second shell 11, the second fixed block 14 is located on the side away from the first shell 10, and a torsion spring 18 is fixedly installed between the first shell 10 and the rotating plate 3. When the device needs to be fixed on the ground, bolts are driven into the second fixed block 14 to complete the fixation of the device.

[0030] In this embodiment, specifically: a through hole 1501 is opened on the fixed plate 15 for accommodating one end of the telescopic square rod 12, and the two fixed plates 15 are located on the side close to the base plate 1. The telescopic square rod 12 can be installed to extend outward, so that the contact area between the device and the ground is increased after the telescopic square rod 12 is extended outward, so that the device is more stable when used.

[0031] When the utility model is in operation, when the second telescopic component 5 needs to be unfolded, the device unfolds as follows: Figure 1 As shown, the device is before being unfolded, and the second telescopic component 5 is located at the lower side of the rotating plate 3, and one end of the telescopic square rod 12 is inserted into the fixed plate 15. When it is necessary to unfold, the telescopic square rod 12 is pressed, and the telescopic square rod 12 squeezes the first spring 13, and the telescopic square rod 12 is rotated. The rotation of the telescopic square rod 12 drives the first shell 10, the second shell 11, the first spring 13, and the telescopic square rod 12 to rotate. When the telescopic square rod 12 rotates, the contact area between the device and the ground increases. Because the contact area between the device and the ground increases, the high device is more stable after being placed on the ground.

[0032] When the first telescopic component 4 needs to be retracted, the multiple threaded tubes 7 and the fixing strip 9 that are threadedly arranged in sequence are disassembled and separated, and the multiple threaded tubes 7 are rotated, and the multiple threaded tubes 7 are retracted, and the rotating shell 6 is rotated. After the rotating shell 6 is rotated, the rotating shell 6 is located at the lower side of the rotating component 2, and the two rotating components 2 are rotated, and the device is folded and retracted, and the volume of the device is reduced.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
