Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a mobile safety belt fastening device. Background Technology
[0002] In construction, equipment maintenance, and high-altitude installation operations, worker safety is a core element in ensuring construction safety. Safety belts, as crucial protective equipment to prevent falls, rely heavily on the stability and reliability of their attachment points to determine their protective effectiveness. However, the application of safety belt attachment devices in current work environments still faces numerous problems, as detailed below: First, the existing clamping structures are mostly of a single specification, which makes it difficult to adapt to carriers of different sizes. In complex working environments, they are prone to problems with unstable fixation, resulting in a significant decrease in clamping stability. Secondly, some construction sites use special hanging devices that are welded or bolted. However, these devices are fixed in position and cannot be adjusted to meet the movement needs of workers. When the work area changes, the devices need to be disassembled and reinstalled, which not only increases the preparation time for the work, but may also damage the carrier structure due to frequent disassembly, affecting the overall stability. Utility Model Content
[0003] The purpose of this invention is to provide a mobile safety belt fastening device that solves the problems of poor adaptability of the existing device's clamping structure and unstable fixation in complex environments, as well as the problem that traditional fixed fastening devices cannot adjust their position as the operator moves, thus balancing clamping stability and usage flexibility.
[0004] To achieve the above objectives, this utility model provides a mobile seat belt fastening device, including a clamping plate, a baffle fixedly connected to the outer side of the clamping plate, a horizontal plate fixedly connected to the inner side of the baffle, a sliding component provided on the inner side of the horizontal plate, and a cover plate provided on the outer side of the sliding component.
[0005] Preferably, the clamping plate body has a U-shaped structure, the upper end face of the clamping plate is provided with a first connecting hole, and two connecting cylinders are respectively installed on the side plate surface of the clamping plate, and the two connecting cylinders are symmetrically arranged between each other.
[0006] Preferably, the inner end face of the connecting cylinder is flush with the inner end face of the clamping plate, the inner wall of the connecting cylinder is threaded, the internal thread of the connecting cylinder is connected to a locking screw, and a pressure plate is installed on the front end surface of the locking screw.
[0007] Preferably, the baffle surface is provided with a second connecting hole, and both the second connecting hole and the first connecting hole are threaded inside, and the second connecting hole and the first connecting hole have the same diameter. Thus, during fixed installation, the clamping plate is placed inside the baffle, so that the second connecting hole and the first connecting hole are concentric, and then the bolts are screwed into the second connecting hole and the first connecting hole to achieve a fixed connection between the baffle and the clamping plate.
[0008] Preferably, the baffle body has a U-shaped structure, and an inclined reinforcing rod is installed at each of the left and right ends of the baffle. The other end of the reinforcing rod is fixedly connected to the upper and lower end surfaces of the horizontal plate by welding.
[0009] Preferably, the sliding assembly includes a transverse sliding groove disposed on the inner side of the cross plate, a sliding plate is slidably fitted in the transverse sliding groove, and a connecting screw is fixedly installed on the outer end of the sliding plate. The number of connecting screws is two, and they are symmetrically arranged.
[0010] Preferably, the surface of the cover plate has two through holes, which are matched with the connecting screw. The connecting screw is engaged in the through holes, and the outer end of the connecting screw is fixedly connected to the cover plate by a nut.
[0011] Preferably, a fixing ring is welded to the middle position of the outer end face of the cover plate, and the safety belt buckle of the worker is engaged in the fixing ring.
[0012] Therefore, the present invention adopts the above-mentioned mobile seat belt fastening device, and the technical effects are as follows: 1) A connecting cylinder is fixedly installed on the surface of the side plate of the clamping plate. The connecting cylinder has a thread inside and a locking screw is connected inside the thread. When the clamping plate is clamped on the carrier, the front pressure plate is pushed to the carrier surface by rotating the locking screw. Since the inner end face of the connecting cylinder is flush with the inner end face of the clamping plate, the pressure plate can fit tightly against the carrier. The friction and extrusion forces firmly fix the entire device on the carrier, preventing the device from shifting or falling off during operation.
[0013] 2) The surface of the baffle has a second connecting hole, and the surface of the clamping plate has a first connecting hole. The bolt passes through the second connecting hole and is threaded into the first connecting hole to fix the baffle and the clamping plate. This can transfer the tensile load of the operator to the fixed carrier. The inclined reinforcing rods at the left and right ends of the baffle are fixedly connected to the horizontal plate respectively. The vertical and horizontal forces borne by the horizontal plate are distributed by the triangular stabilizing structure, which prevents the connection node between the baffle and the horizontal plate from deforming due to excessive force and improves the bending resistance of the overall structure.
[0014] 3) In the sliding assembly, the sliding plate is slidably mounted in the transverse groove of the horizontal plate and can move horizontally along the direction of the transverse groove, driving the connecting screw on the surface to move synchronously. The cover plate is sleeved on the connecting screw through the surface through hole, forming a linkage structure between the sliding plate and the cover plate, realizing the position adjustment of the cover plate on the surface of the horizontal plate. When the cover plate moves to a position that is convenient for the operator to attach, the cover plate is fixed to the outer end surface of the horizontal plate by tightening the nut on the surface of the connecting screw, locking the current position and ensuring the stability of the attachment point.
[0015] 4) The fixing ring on the outer end face of the cover plate serves as a direct attachment component. Workers attach the buckle on the surface of the safety belt to the fixing ring. The load of the human body is transferred to the cover plate through the fixing ring, and then transferred to the fixed carrier through the sliding plate, the cross plate, the baffle and the clamping plate, forming a complete force transmission path to achieve safety protection for workers.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1 like Figure 1 , Figure 2 As shown, this utility model provides a mobile seat belt fastening device, including a clamping plate 1; the main body of the clamping plate 1 is a U-shaped structure, a first connecting hole 101 is opened on the upper end surface of the clamping plate 1, and two connecting cylinders 102 are installed on the side plate surface of the clamping plate 1.
[0022] like Figure 3 , Figure 4 As shown, the inner end face of the connecting cylinder 102 is flush with the inner end face of the clamping plate 1. The inner wall of the connecting cylinder 102 is threaded, and the internal thread of the connecting cylinder 102 is connected to the locking screw 2. A pressure plate 201 is installed on the front end surface of the locking screw 2.
[0023] When in use, after the clamping plate 1 is clamped onto the carrier, the front pressure plate 201 is pushed to press against the carrier surface by rotating the locking screw 2. Since the inner end face of the connecting cylinder 102 is flush with the inner end face of the clamping plate 1, the pressure plate 201 can fit tightly against the carrier. The entire device is firmly fixed on the carrier by friction and extrusion, preventing the device from shifting or falling off during operation.
[0024] A baffle 4 is fixedly connected to the outer side of the clamping plate 1. The surface of the baffle 4 has a second connecting hole 401. Both the second connecting hole 401 and the first connecting hole 101 have threads, and their diameters are the same. During installation, bolts are passed through the second connecting hole 401 and the first connecting hole 101 in sequence to fix the baffle 4 to the outer end face of the horizontal plate 3. In use, fixing the baffle 4 to the clamping plate 1 transfers the tensile load from the operator to the fixed carrier.
[0025] like Figure 5As shown, the main body of the baffle 4 is a U-shaped structure. An inclined reinforcing rod 402 is installed at each of the left and right ends of the baffle 4. The other end of the reinforcing rod 402 is fixedly connected to the upper and lower end faces of the horizontal plate 3. During use, the inclined reinforcing rods 402 at both ends of the baffle 4 are fixedly connected to the horizontal plate 3. The triangular stabilizing structure disperses the vertical and lateral forces borne by the horizontal plate 3, preventing deformation of the connection point between the baffle 4 and the horizontal plate 3 due to excessive force, thus improving the overall structure's resistance to bending.
[0026] The main body of the horizontal plate 3 is a long strip structure. A baffle 4 is welded to the upper and lower ends of the horizontal plate 3. A sliding component is provided on the inner side of the horizontal plate 3. The sliding component includes a transverse sliding groove 301 set on the inner side of the horizontal plate 3. A sliding plate 5 is slidably installed in the transverse sliding groove 301. A connecting screw 501 is fixedly installed on the outer end of the sliding plate 5. There are two connecting screws 501, which are symmetrically arranged.
[0027] The outer side of the sliding component is provided with a cover plate 6, such as Figure 6 As shown, a retaining ring 602 is welded to the middle of the outer end face of the cover plate 6, and the buckle on the surface of the worker's safety belt can be engaged inside the retaining ring 602. Two through holes 601 are formed on the surface of the cover plate 6, and the connecting screw 501 on the outer end face of the sliding plate 5 is engaged in the through holes 601 on the surface of the cover plate 6. The outer end of the connecting screw 501 is fixedly connected to the cover plate 6 by a nut. A retaining ring 602 is welded to the middle of the outer end face of the cover plate 6, and the worker's safety belt buckle is engaged inside the retaining ring 602.
[0028] During use, once the cover plate 6 is moved to a position convenient for the operator to attach, the cover plate 6 is fixed to the outer end surface of the horizontal plate 3 by tightening the nut on the surface of the connecting screw 501, thus locking the current position and ensuring the stability of the attachment point.
[0029] The working principle of this embodiment: In this utility model, the clamping plate 1 adopts a U-shaped main structure, which can be directly clamped onto plate-shaped carriers such as steel structures and wall edges at the work site. The inclusiveness of the U-shaped opening can accommodate fixed foundations of different specifications. A connecting cylinder 102 is fixedly installed on the surface of the side plate of the clamping plate 1. The connecting cylinder 102 has a thread inside and a locking screw 2 is connected inside the thread. When the clamping plate 1 is clamped onto the carrier, the locking screw 2 is rotated to push the front pressure plate 201 to press against the surface of the carrier. Since the inner end face of the connecting cylinder 102 is flush with the inner end face of the clamping plate 1, the pressure plate 201 can fit tightly against the carrier. Through friction and extrusion, the entire device is firmly fixed to the carrier, preventing the device from shifting or falling off during operation.
[0030] A baffle 4 is installed at the top and bottom of the horizontal plate 3. The surface of the baffle 4 has a second connecting hole 401, and the surface of the clamping plate 1 has a first connecting hole 101. Bolts pass through the second connecting hole 401 and are threaded into the first connecting hole 101 to fix the baffle 4 and the clamping plate 1. This can transfer the tensile load of the operator to the fixed carrier. The inclined reinforcing rods 402 at the left and right ends of the baffle 4 are fixedly connected to the horizontal plate 3. The vertical and horizontal forces borne by the horizontal plate 3 are distributed by the triangular stabilizing structure, which prevents the connection node between the baffle 4 and the horizontal plate 3 from deforming due to excessive force and improves the bending resistance of the overall structure.
[0031] The sliding plate 5 is slidably mounted in the transverse groove 301 of the horizontal plate 3, and can move horizontally along the direction of the transverse groove 301, driving the connecting screw 501 on the surface to move synchronously. The cover plate 6 is sleeved on the connecting screw 501 through the surface through hole 601, forming a linkage structure between the sliding plate 5 and the cover plate 6, realizing the position adjustment of the cover plate 6 on the surface of the horizontal plate 3. When the cover plate 6 moves to a position that is convenient for the operator to attach, the nut on the surface of the connecting screw 501 is tightened to fix the cover plate 6 on the outer end surface of the horizontal plate 3, locking the current position and ensuring the stability of the attachment point.
[0032] The fixing ring 602 on the outer end face of the cover plate 6 serves as a direct fastening component. The worker attaches the buckle on the surface of the safety belt into the fixing ring 602. The load of the human body is transferred to the cover plate 6 through the fixing ring 602, and then finally transferred to the fixed carrier through the sliding plate 5, the horizontal plate 3, the baffle 4 and the clamping plate 1, forming a complete force transmission path to achieve safety protection for the worker.
[0033] Therefore, the present invention adopts the above-mentioned mobile safety belt fastening device, which not only solves the problems of poor adaptability of the existing device clamping structure and unstable fixation in complex environments, but also solves the problem that the traditional fixed fastening device cannot adjust its position with the movement of the operator, thus taking into account both clamping stability and usage flexibility.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
