Technical Field

[0001] This utility model relates to the field of electrical equipment maintenance, and in particular to a safety belt holder for electrical equipment maintenance. Background Technology

[0002] In modern industrial production, the maintenance of electrical equipment is a crucial step in ensuring its normal operation and preventing malfunctions. However, since electrical equipment is usually installed on steel supports at high altitudes, and maintenance work often involves working at heights, safety belt hangers are required to suspend safety belts during the maintenance process.

[0003] Existing safety belt brackets typically employ simple hook or clamping structures, limiting their applicability. For instance, the steel supports for electrical equipment are often welded from various steel profiles such as H-beams and channel steel. These brackets are often not interchangeable, requiring different brackets to be used depending on the specific equipment support type, increasing usage costs and management complexity. Furthermore, in some complex equipment support environments, it may be necessary to install brackets between two steel profiles or at specific locations on a particular steel profile. Traditional brackets struggle to achieve this flexible installation method, necessitating optimization and improvement. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "inner," "outer," "vertical," "circumferential," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] In the description of this utility model, "first feature" and "second feature" may include one or more of the indicated features. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the indicated features.

[0034] like Figures 1-6 The electrical equipment maintenance safety belt bracket shown includes: a claw, a drive component, and a hanging rod 3.

[0035] like Figure 1 and Figure 2 As shown, there are two grippers arranged opposite each other, one on the left and one on the right. The two grippers are a fixed gripper 1 and a movable gripper 2. The fixed gripper 1 is equipped with a hanging rod 3. The driving component is connected to the movable gripper 2 to drive the movable gripper 2 to move closer to or away from the fixed gripper 1, thereby facilitating the clamping and fixing of this device.

[0036] like Figure 2 , Figure 3 and Figure 4As shown, each claw includes a base plate 5 and a detachable locking plate 6 disposed at the front end of the base plate 5. The left and right sides of the front end of the base plate 5 are respectively provided with first locking portions, and the locking plate 6 is provided with a second locking portion that can be detachably locked with the first locking portions. When the second locking portion is engaged with the first locking portion on the left, the claw is an L-shaped claw with the opening facing the left. When the second locking portion is engaged with the first locking portion on the right, the claw is an L-shaped claw with the opening facing the right.

[0037] Specifically, in this solution, the base plate 5 and the card plate 6 on each claw can be detached and combined. The card plate 6 can be installed on the left or right side of the base, thereby forming two types of claws: one is an L-shaped claw with the opening facing the left, and the other is an L-shaped claw with the opening facing the right.

[0038] So during use, such as Figure 1 and Figure 2 As shown, when the movable claw 2 becomes an L-shaped claw with its opening facing left, and the fixed claw 1 becomes an L-shaped claw with its opening facing right, both claws are outward-expanding claws. In this case, when the driving component drives the movable claw 2 away from the fixed claw 1, the two claws can abut between the two channel steels or H-beams of the electrical equipment bracket, thereby achieving the fixation of the device.

[0039] like Figure 4 As shown, when the movable claw 2 becomes an L-shaped claw with its opening facing right, and the fixed claw 1 becomes an L-shaped claw with its opening facing left, both claws are inward-facing. In this case, when the driving component drives the movable claw 2 to approach the fixed claw 1, the two claws can be engaged with a channel steel or H-beam of the electrical equipment bracket, thereby fixing the device.

[0040] Therefore, by changing the structural shape of the two claws, this device can be fixed by either abutting between two steel sections or by clamping onto a steel section, depending on the actual situation. The fixing method is flexible and can meet a variety of fixing needs. Moreover, the overall structure of this device is simple, highly portable, and easy to use.

[0041] In a further configuration, the hanging rod 3 may be equipped with several seat belt loops 4 to facilitate the suspension of the seat belt. The hanging rod 3 is located on the base plate 5 of the fixed claw 1 and is situated on the side of the base plate 5 of the fixed claw 1 away from the movable claw 2, thereby avoiding interference with the adjustment of the distance between the two claws.

[0042] In some implementations, such as Figure 2 and Figure 3As shown, the first engaging part is a slot 7, with slots 7 extending vertically on both the left and right sides of the front end of the base plate 5. The second engaging part is a rail 8, with a rail 8 extending vertically on the plate 6. The rail 8 vertically engages with the slot 7 and forms a damped engagement. Damped engagement here refers to a certain damping friction between the rail 8 and the slot 7. This damping friction does not affect the normal engagement of the rail 8 and the slot 7, but requires increased force during assembly and disassembly. When the rail 8 and the slot 7 are engaged, the presence of this damping friction prevents them from easily separating and causing the plate 6 to detach from the base plate 5, thereby improving safety.

[0043] In practical applications, the inner wall of the slot 7 is fixedly provided with an elastic anti-slip pad 9. The rail 8 is inserted into the slot 7 and squeezes the anti-slip pad 9. The squeezed elastic anti-slip pad 9 can provide damping friction to ensure that the claws will not loosen during use.

[0044] In some implementations, such as Figure 5 and Figure 6 As shown, the driving component includes a screw shaft 10 and a nut 11. The screw shaft 10 is fixedly connected to the base plate 5 of the fixed claw 1. The base plate 5 of the movable claw 2 has a shaft hole, through which the screw shaft 10 passes and is threadedly connected to the nut 11. An annular anti-detachment rail 13 is provided on one side of the nut 11 near the base plate 5 of the movable claw 2. A corresponding annular anti-detachment groove 12 is provided on the base plate 5 of the movable claw 2. The anti-detachment rail 13 and the anti-detachment groove 12 are rotatably engaged. The anti-detachment rail 13 is a trapezoidal rail with a trapezoidal cross-section, the anti-detachment groove 12 is a trapezoidal groove with a trapezoidal cross-section, and the nut 11 is a hand-tightening nut 11 with a handle.

[0045] Since the nut 11 and the base plate 5 of the movable claw 2 are rotatably engaged by the anti-detachment rail 13 and the anti-detachment groove 12, that is, the anti-detachment rail 13 can rotate within the anti-detachment groove 12 but cannot disengage from the anti-detachment groove 12, when the nut 11 is turned, the nut 11 moves along the axial direction of the screw shaft 10, which can drive the base plate 5 of the movable claw 2 to move. At the same time, the base plate 5 will not affect the rotation of the nut 11. This structure is simple and easy to use.

[0046] In summary, this device has the following characteristics:

[0047] 1. The device has a simple overall structure with few components, making it easy to carry and use, and suitable for rapid deployment in various electrical equipment maintenance scenarios;

[0048] 2. This device is fixed to the steel frame of the electrical equipment by using two claws. Since the base plate 5 and the clamping plate 6 of each claw can be disassembled and reassembled to switch the claw to an outward expansion form or an inward retraction form, it can adapt to various fixing requirements by switching the form of the claw and cooperating with the driving component. Whether it is against two steel sections or clamped on a certain steel section, it can achieve a stable fixation. The structure is simple, the fixing is flexible, and the practicality is strong.

[0049] Although some embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention are all within the scope of protection of the claims of the present invention.
