Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of safety warning device technology, and more specifically, to a safety warning device for engineering supervision. Background Technology

[0002] Construction supervision refers to a professional service activity in which a qualified supervision unit, entrusted by the client, monitors the construction work of the contractor on behalf of the client, based on nationally approved project construction documents, relevant laws and regulations, construction supervision contracts, and other construction contracts. Construction supervision is a paid engineering consulting service, commissioned by the client. The main basis for supervision is laws, regulations, technical standards, relevant contracts and documents. The principles of supervision are legality, integrity, impartiality, and science. The purpose of supervision is to ensure the quality and safety of construction projects, improve the level of construction, and maximize investment benefits. Construction supervision is conducted at the construction site and requires the use of safety warning devices to alert personnel.

[0003] Existing safety warning devices typically consist of a bracket and a warning sign. The warning sign is installed on the bracket to alert passersby. The bracket is an openable bracket, which supports the warning sign when it is unfolded. However, after the bracket is unfolded, staff need to fix it again to ensure its stability. The operation is cumbersome and it is difficult to quickly fix the bracket after it is unfolded. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a safety warning device for engineering supervision, which solves the technical problem that existing safety warning devices are difficult to quickly fix after the support is deployed.

[0005] According to one aspect, at least one embodiment of this disclosure provides a safety warning device for engineering supervision, including a connecting base, with brackets provided on both sides of the connecting base. The brackets are hinged to the connecting base via hinges, and a warning sign is provided on the outer side of the brackets. The device also includes a housing, a T-shaped limiting plate, a transmission plate, a positioning insert plate, an adjustment mechanism, a trigger-type locking mechanism, a positioning seat, and a trigger element. Two housings are mounted on the upper side of one of the two brackets via support blocks. The two housings are symmetrically arranged. The T-shaped limiting plate is installed in the middle of the inner wall of the housing, and a transmission plate is sleeved on the T-shaped limiting plate. The transmission plate is capable of horizontally moving along the T-shaped limiting plate. The transmission plate is movable, with a positioning plate installed on one side of each side. The positioning plate moves synchronously with the transmission plate. The adjustment mechanism is located inside the housing and is used to adjust the position of the transmission plate on the T-shaped limiting plate. The trigger-type snap-fit ​​mechanism is located on the upper side of the housing and is used to snap-fit ​​and position the adjustment mechanism. Two positioning seats are installed on the upper side of the other of the two brackets via a support block. The positioning seats are used to fix the two brackets after they are unfolded. The trigger is installed on the upper side of the positioning seat and is used to trigger the trigger-type snap-fit ​​mechanism.

[0006] The adjustment mechanism includes an adjustment rod, a movable plate, a transmission component, and a first return spring. The adjustment rod is inserted into the outside of the housing and can move horizontally inside the housing. The movable plate is installed on the inner end of the adjustment rod and moves synchronously with the adjustment rod. The transmission component is installed on the inner side of the movable plate, and the other side of the transmission component is connected to the outer side of the transmission plate. When the movable plate moves horizontally, it can drive the transmission plate to move horizontally along the T-shaped limiting plate through the transmission component. The first return spring is sleeved on the adjustment rod, and its two ends are respectively connected to the housing and the movable plate.

[0007] As a preferred embodiment of the safety warning device for engineering supervision described in this utility model, in order to realize the transmission between the moving plate and the transmission plate, the transmission component is composed of a connecting plate and two hinge seats. The connecting plate is sleeved on the two hinge seats. The outer hinge seat is connected to the moving plate, and the inner hinge seat is connected to the transmission plate.

[0008] The trigger-type latching mechanism includes a trigger assembly and a return assembly. The trigger assembly includes a U-shaped mounting rod, a rotating ring, a locking plate, and a trigger seat. The U-shaped mounting rod is mounted on the upper side of the housing. The rotating ring is sleeved on the U-shaped mounting rod and can rotate on the U-shaped mounting rod. The locking plate is mounted on the lower side of the rotating ring and deflects around the rotating ring as it rotates. The trigger seat is mounted on the upper side of the rotating ring and deflects around the rotating ring as it rotates. The return assembly includes a limiting guide post, a second return spring, and a limiting disc. The limiting guide post is mounted on the upper side of the housing. The trigger seat is sleeved on the limiting guide post and can move along the limiting guide post. The second return spring is sleeved on the limiting guide post, and its two ends are connected to the housing and the trigger seat, respectively. The limiting disc is mounted on the top of the limiting guide post and is used to limit the position of the trigger seat.

[0009] As a preferred embodiment of the safety warning device for engineering supervision described in this utility model, in order to achieve the snap-fit ​​positioning of the housing and the moving plate, a slot is provided on the upper side of both the housing and the moving plate, and the width of the slot is adapted to the width of the plate.

[0010] As a preferred embodiment of the safety warning device for engineering supervision described in this utility model, in order to achieve the insertion and positioning between the housing and the positioning seat, a positioning slot is provided on one side of the two sides of the positioning seat, and the width of the positioning slot is adapted to the width of the positioning plate.

[0011] The trigger includes an arc-shaped rod and a toggle push plate. The arc-shaped rod is mounted on the upper side of the positioning seat, and the toggle push plate is mounted on one side of the arc-shaped rod.

[0012] The beneficial effects of the embodiments disclosed herein are as follows:

[0013] In this disclosure, the automatic insertion and fixing of the two brackets after they are unfolded is achieved through the cooperation of the transmission plate, the positioning plate, the adjustment mechanism, the trigger-type snap-fit ​​mechanism, the positioning seat and the trigger element. This achieves automatic fixing of the two brackets after they are unfolded, eliminating the need for staff to reposition the brackets after they are unfolded, thus improving work efficiency and facilitating the operation of staff.

[0014] In this disclosure, the automatic spring-loaded adjustment mechanism is achieved through the cooperation of the trigger-type snap-fit ​​mechanism and the trigger element, so that the adjustment mechanism can synchronously drive the positioning plate to be inserted into the interior of the positioning seat after the two brackets are unfolded. The trigger-type snap-fit ​​mechanism can also play a snap-fit ​​and limit role on the adjustment mechanism after the two brackets are stored, thereby facilitating the automatic fixation of the two brackets that are unfolded again after being stored.

[0015] Compared with the existing safety warning devices, which have the technical problem of being unable to quickly fix the supports after they are deployed, this safety warning device for engineering supervision can automatically insert and fix the two supports at the same time as they are deployed, without the need for manual re-fixing of the supports. It is easy to operate, greatly reduces the time required to fix the supports, and is more convenient to use. Attached Figure Description

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0029] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-4As shown, this embodiment illustrates a safety warning device for engineering supervision, including a connecting base 1, with brackets 2 on both sides of the connecting base 1. The brackets 2 are hinged to the connecting base 1 via hinges 3. A warning sign 4 is provided on the outer side of the brackets 2. The device also includes a housing 5, a T-shaped limiting plate 6, a transmission plate 7, a positioning insert 8, an adjustment mechanism, a trigger-type locking mechanism, a positioning seat 9, and a trigger element. Addressing the technical problem of existing safety warning devices' difficulty in quickly fixing the brackets after deployment, this embodiment achieves rapid fixation of the two brackets 2 after deployment through the cooperation of the transmission plate 7, positioning insert 8, adjustment mechanism, trigger-type locking mechanism, positioning seat 9, and trigger element. The automatic insertion and fixing mechanism enables automatic fixation of the two brackets 2 after they are unfolded, eliminating the need for staff to reposition the unfolded brackets 2, thus improving work efficiency and facilitating operation. Through the cooperation of the trigger-type snap-fit ​​mechanism and the trigger element, the adjustment mechanism is automatically popped in, allowing the adjustment mechanism to synchronously drive the positioning plate 8 into the positioning seat 9 after the two brackets 2 are unfolded. The trigger-type snap-fit ​​mechanism can also act as a snap-fit ​​limiter for the adjustment mechanism after the two brackets 2 are stored, thus facilitating the automatic fixing of the two brackets 2 that are unfolded again after being stored, improving the convenience of the device and making it easier for staff to operate the device.

[0033] like Figure 1 and Figure 2 As shown, two housings 5 ​​are mounted on the upper side of one of the two brackets 2 via a support block. The two housings 5 ​​are arranged symmetrically, as shown in the figure. Figure 3 and Figure 4As shown, a T-shaped limiting plate 6 is installed in the middle of the inner wall of the housing 5. A transmission plate 7 is sleeved on the T-shaped limiting plate 6. A positioning insert plate 8 is installed on one of the two sides of the transmission plate 7. The adjustment mechanism is located inside the housing 5. The adjustment mechanism includes an adjusting rod 101, a moving plate 102, a transmission component 103, and a first return spring 104. The transmission component 103 consists of a connecting plate and two hinge seats. The connecting plate is sleeved on the two hinge seats. The outer hinge seat is connected to the moving plate 102, and the inner hinge seat is connected to the transmission plate. The housing 5 is connected to a trigger-type locking mechanism located on its upper side. This mechanism includes a trigger assembly and a return assembly. The trigger assembly comprises a U-shaped mounting rod 201, a rotating ring 202, a locking plate 203, and a trigger seat 204. Both the housing 5 and the moving plate 102 have slots on their upper sides. The width of the slots matches the width of the locking plate 203, allowing the locking plate 203 to engage and limit the moving plate 102 through the slots. The return assembly includes a limiting guide post 301, a second return spring 302, and a limiting disc 303. Two positioning seats 9 are installed on the upper side of the other bracket 2 via a support block. A positioning slot is provided on one side of the housing 5 and the positioning seat 9. The width of the positioning slot is adapted to the width of the positioning plate 8. The positioning plate 8 can be inserted and positioned by the positioning slot to the housing 5 and the positioning seat 9. A trigger is installed on the upper side of the positioning seat 9. The trigger includes an arc rod 401 and a push plate 402. Through the cooperation of the transmission plate 7, the positioning plate 8, the adjustment mechanism, the trigger-type snap-fit ​​mechanism, the positioning seat 9 and the trigger, the two brackets 2 can be automatically inserted and fixed after being unfolded. Through the cooperation of the trigger-type snap-fit ​​mechanism and the trigger, the adjustment mechanism can be automatically popped in, so that the adjustment mechanism can drive the positioning plate 8 to be inserted into the interior of the positioning seat 9 synchronously after the two brackets 2 are unfolded. The trigger-type snap-fit ​​mechanism can also play a snap-fit ​​and limit role on the adjustment mechanism after the two brackets 2 are stored, thus facilitating the automatic fixation of the two brackets 2 that are unfolded again after being stored.

[0034] Working principle:

[0035] When the device needs to be unfolded, the staff pushes the two brackets 2 to unfold. The brackets 2 deflect around the hinge 3. During the unfolding process, the positioning seat 9 installed on the brackets 2 drives the trigger element to push the trigger seat 204 to move downward along the limit guide post 301. The trigger seat 204 drives the rotating ring 202 to rotate. The rotating ring 202 drives the clamping plate 203 to deflect. When the two brackets 2 are fully unfolded, the clamping and limiting effect of the clamping plate 203 on the moving plate 102 disappears. The moving plate 102 moves towards the normal phase of the transmission plate 7 under the action of the first return spring 104. The moving plate 102 drives the transmission plate 7 to move towards the normal phase of the positioning seat 9 along the T-shaped limit plate 6 through the transmission element 103. The transmission plate 7 drives the positioning insert 8 to be inserted into the positioning seat 9, thereby realizing the insertion and fixing between the two brackets 2 after the device is unfolded.

[0036] When the device needs to be stored, the operator pulls the adjusting rod 101 to move it outward. The adjusting rod 101 drives the moving plate 102 to move outward. The moving plate 102 drives the transmission plate 7 to move in the opposite direction along the T-shaped limiting plate 6 through the transmission component 103. The transmission plate 7 drives the positioning insert 8 to return to its original position. At this time, the moving plate 102 is directly below the slot opened on the housing 5. Then, the operator folds the two brackets 2 for storage. When the brackets 2 are folded for storage, the force applied by the trigger to the trigger seat 204 disappears. Under the action of the second return spring 302, the trigger seat 204 moves upward along the limiting guide post 301. The trigger seat 204 drives the locking plate 203 to lock the moving plate 102 through the rotating ring 202, thereby realizing the automatic return of the adjusting mechanism and the trigger-type locking mechanism.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
