Fixing frame for safety grating

Abstract

The utility model relates to a fixing frame for safety gratings, and aims to solve the technical problems that safety grating bodies on two sides are difficult to calibrate accurately, deviation is easy to occur and potential safety hazards are increased due to the fact that threaded rods on the two sides are difficult to rotate accurately in the same way through manual screwing of the fixing frame for the safety gratings. A positioning structure is arranged on the inner side of the punching machine body, and a set of adjusting structures are symmetrically arranged on the inner side of the positioning structure. The height of the safety grating body is adjusted by moving the movable plate up and down, and after the height of the safety grating body is adjusted to a proper position, the upper end of the U-shaped inserting rod is inserted into the adjusting hole exposed out of the movable plate and closest to the clamping frame, so that the lower end of the U-shaped inserting rod penetrates through one side of the clamping frame to be directly inserted into the inner side of the movable plate. The movable plate and the safety grating body are effectively limited, then the U-shaped insertion rod is pushed to enter the inner side of the plastic buckle, the U-shaped insertion rod is fixed, and the possibility that the U-shaped insertion rod slips off is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of safety grating installation, in particular to a fixing frame for a safety grating. Background Art

[0002] Safety gratings are photoelectric safety protection devices (also known as safety protectors, punch protectors, infrared safety protection devices, etc.). Generally speaking, safety gratings exist in pairs, divided into transmitting ends and receiving ends. In order to protect the safety of operators, stamping machines generally install safety gratings on the operating table. When the hand touches the light of the safety grating and blocks the reception of light, the stamping machine will stop immediately.

[0003] Patent No. CN220338084U discloses a fixing frame for a safety grating, including a punch body, a mounting plate fixedly installed on both sides of the punch body, a column fixedly installed on the top of the mounting plate, a safety grating body fixedly installed on the side of the column close to the punch body, an adjustment mechanism provided on the column, a mounting sleeve fixedly installed on the side of the safety grating body close to the column, and a clamping mechanism for conveniently installing the safety grating body is provided inside the mounting sleeve. The fixing frame for the safety grating, through the provided clamping mechanism, when installing the safety grating body, only needs to connect the mounting sleeve on the safety grating body to the fixing block, and press the fixing block toward one side of the column, and the mounting sleeve will compress the clamping blocks on both sides until the clamping blocks are clamped into the through hole, and the mounting sleeve can be fixed on the fixing block, and the installation of the safety grating body can be completed conveniently, thereby improving the practicality of the device.

[0004] However, the above-mentioned fixing frame for safety grating still has the following disadvantages:

[0005] Although the above device can adjust the installation height of the safety grating body by turning the threaded rod to drive the threaded slider to move the safety grating body up and down, it is difficult to rotate the threaded rods on both sides with the same precision by manual twisting, which makes it difficult to accurately calibrate the safety grating bodies on both sides, which is prone to deviation and increases safety hazards. In view of this, we propose a fixing bracket for the safety grating. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art, meet practical needs, and provide a fixing bracket for a safety grating to solve the technical problem that it is difficult to perform the same precise rotation of the threaded rods on both sides by manual screwing of the above-mentioned device, thereby making it difficult to accurately calibrate the safety grating bodies on both sides, prone to deviations, and increasing safety hazards.

[0007] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a fixing frame for a safety grating, comprising a punch body, a positioning structure is provided inside the punch body, and a group of adjustment structures are symmetrically provided inside the positioning structure;

[0008] The adjustment structure includes a bracket, which is fixed to the surface of the positioning structure. A movable plate is clamped inside the bracket, and a plurality of adjustment holes are evenly opened on one side surface of the movable plate. A safety grating body is fixedly connected to the surface of the movable plate, and a connecting rod is fixedly connected to the surface of the bracket. A plastic buckle is fixedly connected to the end of the connecting rod away from the bracket, and a U-shaped plug rod is clamped inside the plastic buckle.

[0009] Preferably, the safety grating body forms a snap-fit ​​structure with the card frame through a movable plate, and the outer wall of the movable plate is in contact with the inner wall of the card frame.

[0010] Preferably, the spacing between adjacent adjustment holes is the same as the spacing between the two ends of the U-shaped insertion rod, and the ends of the U-shaped insertion rod can be matched and engaged in the adjustment holes.

[0011] Preferably, the outer wall of the U-shaped rod fits with the inner wall of the plastic buckle, and one end of the U-shaped rod passes through one side of the bracket.

A limiting groove is provided on the inner side of the left positioning frame, a limiting plate is engaged inside the limiting groove, and a right positioning frame is fixedly connected to the end of the limiting plate away from the limiting groove. The left positioning frame and the right positioning frame are both connected to the punch body by bolts.

[0013] Preferably, the left positioning frame and the right positioning frame are both Z-shaped, and the right positioning frame forms a sliding engagement structure through a limiting plate and a limiting groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model adjusts the height of the safety grating body by moving the movable plate up and down. After adjusting to the appropriate position, the upper end of the U-shaped rod is inserted into the adjustment hole exposed on the movable plate and closest to the bracket, so that the lower end of the U-shaped rod can pass through one side of the bracket and directly insert into the inner side of the movable plate, effectively limiting the movable plate and the safety grating body, and then pushing the U-shaped rod into the inner side of the plastic buckle to fix the U-shaped rod and reduce the possibility of the U-shaped rod slipping.
