Description

Technical Field

[0001] The utility model relates to the technical field of extraction tools, in particular to a relay extraction tool. Background Art

[0002] Relays are connected to the base. Usually, workers manually extract the relays from the base. Since the relay bases are arranged side by side on the base and are tightly connected between adjacent bases, the distance between adjacent relays is small. Therefore, only the front and rear end faces of the relay are available for workers to hold, resulting in not only high labor intensity for manual extraction of the relay, but also easy damage to the base when the relay is not vertically extracted. Summary of the Invention

[0003] The technical problem to be solved by the utility model is that the labor intensity is high during the extraction process and the base is easily damaged.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a relay extraction tool, including a U-shaped mounting frame, a U-shaped lifting frame vertically and slidably connected to the inner top of the mounting frame, and a clamping block sleeved at the bottom end of the lifting frame. A wedge block is fixedly arranged at the bottom of the inner side wall of the mounting frame, the inclined surface of the wedge block is at the bottom, the top of the clamping block is provided with an inclined surface, the clamping block is slidably arranged relative to the wedge block, the gap between the mounting frame and the relay on the base is less than the sum of the thicknesses of the wedge block and the clamping block, and the inner width of the lifting frame is greater than the width of the relay.

[0005] Preferably, the mounting frame includes horizontally arranged connecting columns and vertical columns fixedly connected to both ends of the connecting columns. The bottom ends of the columns are fixedly connected with adapter blocks, and the bottom surface of the adapter blocks is provided with continuous steps adapted to the top edge of the base.

[0006] Preferably, a connecting rod is fixedly connected between the columns at both ends of the connecting column, and the connecting rod is located at the bottom end of the column.

[0007] Preferably, the columns are located at the edges of the mounting frame.

[0008] Preferably, a spring rod is vertically and fixedly connected to the top end of the lifting frame. The spring rod penetrates through the connecting column, and a spring sleeved outside the spring rod is connected between the connecting column and the lifting frame. A limit block is fixedly arranged at the top end of the spring rod.

[0009] Preferably, a soft package is sleeved on the top of the lifting frame.

[0010] Preferably, a friction plate is arranged on the side wall of the clamping block away from the wedge block.

[0011] The present utility model provides a relay extraction tool. The lifting frame drives the clamping block to move. The clamping block cooperates with the wedge block, and the opposite side walls of the relay are clamped by the clamping block. After clamping, by pulling up the mounting frame, the relay can be pulled out from the base, realizing the rapid clamping of the relay. Moreover, the cooperation between the mounting frame and the base enables the mounting frame to move upward stably, avoiding damage to the base during the relay extraction process.

[0016] As Figure 1 and Figure 2 shown, the present utility model provides a relay extraction tool, including a U-shaped mounting frame, a U-shaped lifting frame 8 vertically and slidably connected to the inner top of the mounting frame, and a clamping block 12 sleeved on the bottom end of the lifting frame 8. A wedge block 7 is fixedly arranged at the bottom of the inner side wall of the mounting frame. The inclined surface of the wedge block 7 is at the bottom. The top of the clamping block 12 is provided with an inclined surface. The clamping block 12 is slidably arranged relative to the wedge block 7. The gap between the mounting frame and the relay 2 on the base 1 is smaller than the sum of the thicknesses of the wedge block 7 and the clamping block 12. The inner width of the lifting frame 8 is greater than the width of the relay 2.

[0017] When extracting the relay 2 on the base 1, the mounting frame is clamped on the base 1. At this time, the clamping block 12 at the bottom of the lifting frame 8 is located below the wedge block 7. After the staff holds the mounting frame, the lifting frame 8 is pulled up by the finger. The lifting frame 8 drives the clamping block 12 to move upward. During the upward movement of the clamping block 12, it will move towards the inner side of the lifting frame 8 and contact the wedge block 7. During the upward movement of the lifting frame 8, the clamping block 12 is in close contact with the outer wall of the relay 2. After the two clamping blocks 12 tightly clamp the relay 2, by pulling up the mounting frame, during the upward movement of the mounting frame, the entire extraction tool moves upward. Since the relay 2 is tightly clamped, the relay 2 is pulled out from the base 1, completing the extraction of the relay 2.

[0018] As Figure 1 and Figure 2As shown in the figure, to ensure the adaptability between the mounting bracket and the base 1 and facilitate the stable buckling of the mounting bracket on the base 1 by the staff. The mounting bracket includes a horizontally arranged connecting column 4 and columns 3 vertically and fixedly connected to both ends of the connecting column 4. The bottom ends of the columns 3 are fixedly connected with adapter blocks 5, and the bottom surface of the adapter blocks 5 is provided with continuous steps adapted to the top edge of the base 1.

[0019] As Figure 1 and Figure 2 shown in the figure, to ensure that the mounting bracket has sufficient strength. A connecting rod 6 is fixedly connected between the columns 3 at both ends of the connecting column 4, and the connecting rod 6 is located at the bottom end of the columns 3.

[0020] As Figure 1 shown in the figure, to prevent the two side-by-side arranged relays 2 from interfering with the connecting rod 6. The columns 3 are located at the edges of the mounting bracket.

[0021] As Figure 1 and Figure 2 shown in the figure, to facilitate the reset of the lifting frame 8. A spring rod 9 is vertically and fixedly connected to the top end of the lifting frame 8. The spring rod 9 penetrates through the connecting column 4. A spring sleeved on the outer side of the spring rod 9 is connected between the connecting column 4 and the lifting frame 8. A limiting block 10 is fixedly arranged at the top end of the spring rod 9. During the process of pulling up the lifting frame 8, the lifting frame 8 compresses the spring on the spring rod 9, and the spring rod 9 is guided through the opening on the connecting column 4. The limiting block 10 is used to prevent the lifting frame 8 from disengaging from the connecting column 4. A supporting block 13 is fixedly connected to the bottom end of the lifting frame 8, and the supporting block 13 is used to support the clamping block 12.

[0022] As Figure 1 and Figure 2 shown in the figure, to improve the comfort of the staff holding the lifting frame 8. A soft package sleeve 11 is sleeved on the top of the lifting frame 8.

[0023] As a preferred embodiment of the present utility model, to enhance the clamping tightness of the clamping block 12 on the relay 2. A friction plate is arranged on the side wall of the clamping block 12 away from the wedge-shaped block 7.
