Description

Technical Field

[0001] This utility model relates to the field of safety and insurance equipment technology, specifically to a safety pull rope switch lock cover device. Background Technology

[0002] Conveyor line equipment is a crucial component of tire production. When an abnormal malfunction occurs, the operator pulls the emergency stop rope to halt the equipment immediately and reports it to maintenance personnel. However, maintenance personnel face significant safety hazards during repairs. For example, uninformed personnel attempting to reset the rope switch during maintenance could cause the equipment to malfunction, resulting in unavoidable injury to the personnel attempting to handle the malfunction.

[0003] Therefore, there is an urgent need to design a safety pull-rope switch lock cover for locking and control, thereby reducing safety hazards. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a safety pull-cord switch lock cover device.

[0005] The technical solution of this utility model is: a safety pull cord switch lock cover device, including a cover, a U-shaped rod and a lock. The cover is a square box shape with openings at the bottom and right side. Two vertical support blocks are provided on the inner wall of the front plate of the cover, and a receiving cavity for accommodating the reset button of the safety pull cord switch is formed between the two support blocks. The lower part of the front plate and the back plate of the cover are provided with two first through holes adapted to the U-shaped rod. The two sets of first through holes are arranged opposite to each other. One end of the U-shaped rod is provided with a lock hole for installing the lock.

[0006] When the protective cover is fitted onto the outside of the safety pull rope switch and its rear bracket from top to bottom, the support block contacts the front of the safety pull rope switch, the back plate of the protective cover contacts the bracket, and the reset button of the safety pull rope switch is located inside the receiving cavity and does not contact the front plate of the protective cover; when the U-shaped rod is installed on the protective cover through the two sets of first through holes, its two longitudinal arms are located on the left and right sides of the bracket respectively, and below the safety pull rope switch.

[0007] Preferably, it also includes a through strip, which is adapted to the gap formed between the through strip and the pull rod and the pull rod mounting base, with a limiting member at one end and a lock hole for installing a lock at the other end; the front plate and the back plate of the cover are both provided with a second through hole for inserting the through strip, and the two second through holes are arranged opposite each other.

[0008] Preferably, the limiting member is a limiting plate.

[0009] Preferably, the protective cover, U-shaped rod, and through strip are all made of steel.

[0010] Preferably, the protective cover has an opening on the left side.

[0011] Preferably, the lock is a padlock.

[0012] Preferably, the lock is an industrial safety padlock.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This device has a simple structure, is easy to install, and is highly practical. By locking the safety pull rope switch with a protective cover, U-shaped rod, and lock, it can prevent unauthorized personnel from resetting the safety pull rope switch during maintenance, thus reducing safety hazards. The cooperation between the strip and the protective cover can prevent the safety pull rope switch buckle from returning to its original position, thereby adding an extra layer of safety.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0022] Reference Figure 1-4 As shown, a safety pull cord switch lock cover device includes a cover 7, a U-shaped rod 11, and a lock. The cover 7 is a square box with openings at the bottom and right side. Two vertical support blocks 8 are provided on the inner wall of the front plate of the cover 7, and a receiving cavity for accommodating the reset button 2 of the safety pull cord switch 1 is formed between the two support blocks 8. The lower part of the front plate and the back plate of the cover 7 are provided with two first through holes 9 adapted to the U-shaped rod 11. The two sets of first through holes 9 are arranged opposite to each other. One end of the U-shaped rod 11 is provided with a lock hole 12 for installing the lock.

[0023] When the cover 7 is fitted onto the outside of the safety pull rope switch 1 and its rear bracket 6 from top to bottom, the support block 8 contacts the front of the safety pull rope switch 1, the back plate of the cover 7 contacts the bracket 6, and the reset button 2 of the safety pull rope switch 1 is located in the receiving cavity and does not contact the front plate of the cover 7. At this time, the cover 7 cannot move forward, backward, left, or right. When the U-shaped rod 11 is installed on the cover 7 through the two sets of first through holes 9, its two longitudinal arms are located on the left and right sides of the bracket 6 respectively, and below the safety pull rope switch 1. At this time, the cover 7 cannot be moved up and removed.

[0024] More specifically, the left side of the protective cover 7 has an opening, and the side section of the protective cover 7 is door-shaped.

[0025] Furthermore, the lock in this embodiment is a padlock.

[0026] Before maintenance, the protective cover 7 is fitted from top to bottom onto the outside of the safety pull rope switch 1 and its rear bracket 6. Then, the U-shaped rod 11 is passed through the two sets of first through holes 9 and locked in place at the bottom of the protective cover 7. Finally, the padlock is installed into the lock hole 12 of the U-shaped rod 11. The padlock key is carried by the maintenance personnel, and unauthorized personnel cannot remove this device, thus preventing them from pressing the reset button 2. Example 2

[0027] As a preferred embodiment of this utility model, this embodiment adds a threading strip 13 based on embodiment one, specifically as follows:

[0028] Reference Figure 1-5 As shown, this embodiment also includes a through strip 13, which is adapted to the gap formed between the through strip 13 and the pull rod 4 and the pull rod mounting seat 3. One end of the through strip 13 is provided with a limiting member 14, and the other end is provided with a lock hole 12 for installing a lock. The front plate and the back plate of the cover 7 are both provided with second through holes 10 for inserting the through strip 13, and the two second through holes 10 are arranged opposite each other.

[0029] More specifically, the limiting component 14 is a limiting plate, and the protective cover 7, U-shaped rod 11 and through strip 13 are all made of steel.

[0030] After the protective cover 7 and U-shaped rod 11 are installed, install the through strip 13, allowing it to pass through the gap between the two second through holes 10 and the gap between the pull rod 4 and the pull mount 3. Finally, install the padlock into the lock hole 12 of the through strip 13. The through strip 13 passes through the gap between the pull rod 4 and the pull mount 3, preventing the pull 5 from returning to its original position, thus adding an extra layer of security. Example 3

[0031] As a preferred embodiment of the present invention, this embodiment differs from Embodiment 2 in that the lock in this embodiment is an industrial safety padlock.

[0032] In summary, this device has a simple structure, is easy to install, and is highly practical. By locking the safety pull rope switch 1 with the protective cover 7, U-shaped rod 11, and lock, it can prevent unauthorized personnel from resetting the safety pull rope switch 1 during maintenance, thus reducing safety hazards. Through the cooperation of the through strip 13 and the protective cover 7, the pull buckle 5 of the safety pull rope switch 1 can not be returned to its original position, thereby adding an extra layer of safety.

[0033] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
