Description

Technical Field

[0001] The utility model relates to the technical field of a limit seat, in particular to a limit seat structure of general mechanical equipment. Background Art

[0002] In general mechanical equipment, a limit seat is a device specially designed to limit the travel or position of mechanical moving parts, aiming to prevent the moving parts from exceeding the predetermined range, thereby ensuring the safety and stability of equipment operation.

[0003] When the existing limit seat is in use, a limit block is usually opened on the upper end of the limit seat or a limit block is installed on the upper end of the limit seat to limit the operation of the mechanical moving parts. Since the limit seat has only one limiting method, when the limit groove or the limit block fails, the mechanical moving parts will exceed the operating range, posing a safety hazard. Therefore, it is necessary to provide a limit seat that can realize a secondary limiting structure to limit the mechanical equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a limit seat structure for general mechanical equipment to solve the problem proposed in the above background technology that when the existing limit seat is used, a limit block is usually opened at the upper end of the limit seat or a limit block is installed at the upper end of the limit seat to limit the operation of the mechanical moving parts. Since the limit seat has only one limiting method, when the limit groove or the limit block fails, the mechanical moving parts will exceed the operating range, posing a safety hazard.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a limit seat structure of general mechanical equipment, comprising:

[0007] Limit seat body;

[0008] A movable component, the movable component comprising a placement slot, a movable plate, a first fixed shaft, a second fixed shaft, a slide slot, a telescopic spring and a pressure sensor;

[0009] The placement slot is opened at the central position of the upper end of the limiting seat body, the movable plate is placed inside the placement slot, the first fixed axis is located at the upper end position on one side of the placement slot, the second fixed axis is located at the lower end position on the other side of the placement slot, the sliding slot is opened on one side of the movable plate, the telescopic spring is fixedly connected to one side of the upper end of the movable plate, and the pressure sensor is fixedly connected to one side of the top end inside the placement slot.

[0010] Furthermore, the first fixed shaft and the second fixed shaft extend outward through both ends of the movable plate, and a through hole is provided inside the limit seat body relative to the first fixed shaft and the second fixed shaft.

[0011] Furthermore, the movable plate is in an inclined upward state, and the top end of the telescopic spring is fixedly connected to the bottom end of the pressure sensor.

[0012] Furthermore, the second fixed shaft is located at one end of the slide slot, and the pressure sensor is electrically connected to a power source of an external device.

[0013] Furthermore, it also includes a limiting assembly, which includes a hollow groove, a fixing column, a fixing nut, a slide rail and a limiting plate.

[0014] The hollow groove is opened on both sides of the bottom end of the limit seat body, the fixed column is placed inside the hollow groove, the fixing nut is threadedly connected to the outer surface of one end of the fixed column, the slide rail is fixedly connected to the top end of the fixed column, and the limit plate is fixedly connected to the outer end of the slide rail.

[0015] Furthermore, the outer surface of one end of the fixing column has a threaded structure opened relative to the fixing nut, and the limiting plate is in an inclined inward state.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The utility model sets a movable component. When the moving part of the mechanical equipment moves to the limit position, the moving part of the mechanical equipment drives the movable plate to move downward, the movable plate rotates along the first fixed axis, and drives the second fixed axis to move upward. One end of the movable plate and the second fixed axis move upward to compress the telescopic spring. When the elastic force of the telescopic spring reaches the set value, the pressure sensor controls the external power supply to be turned off, and the upper end of the movable plate exceeds the upper end of the limit seat, so that the moving part of the mechanical equipment can be limited for the second time.

[0018] 2. Based on beneficial effect 1, by setting a limit assembly, the moving parts of the mechanical equipment are blocked by the inwardly placed limit plate, thereby achieving the limiting effect, and when the limit plate is worn, the position of the fixed column can be moved, thereby changing the position of the limit plate, so that the limit plate can still limit the moving parts of the mechanical equipment, and the service life is longer.

[0029] See also Figure 1-2 As shown, this embodiment is a limit seat structure of a general mechanical equipment, including:

[0030] Limit seat body 11;

[0031] The movable assembly includes a placement slot 21, a movable plate 22, a first fixed shaft 23, a second fixed shaft 24, a slide slot 25, a telescopic spring 26 and a pressure sensor 27;

[0032] The placement slot 21 is opened at the central position of the upper end of the limiting seat body 11, the movable plate 22 is placed in the inner position of the placement slot 21, the first fixed shaft 23 is located at the upper end position of one side of the placement slot 21, the second fixed shaft 24 is located at the lower end position of the other side of the placement slot 21, the slide slot 25 is opened at one side of the movable plate 22, the telescopic spring 26 is fixedly connected to one side of the upper end of the movable plate 22, and the pressure sensor 27 is fixedly connected to one side of the top of the placement slot 21;

[0033] The placement groove 21 is used to place the movable plate 22, the movable plate 22 is used for secondary limiting, the first fixed shaft 23 is used to support the movable plate 22, the second fixed shaft 24 is used to limit the rotation of the movable plate 22, the slide groove 25 is used to guide the movement of the second fixed shaft 24, the telescopic spring 26 is used to be compressed under the drive of the movable plate 22, and the pressure sensor 27 is used to measure the elastic force of the telescopic spring 26;

[0034] The first fixed shaft 23 and the second fixed shaft 24 extend outward through both ends of the movable plate 22, and the limiting seat body 11 has a through hole opened relative to the first fixed shaft 23 and the second fixed shaft 24;

[0035] The movable plate 22 can rotate along the first fixed axis 23;

[0036] The movable plate 22 is in an upward tilted state, and the top end of the telescopic spring 26 is fixedly connected to the bottom end of the pressure sensor 27;

[0037] When the movable plate 22 rotates until the lower end of the slide slot 25 contacts the lower end of the second fixed shaft 24, the second fixed shaft 24 blocks the movable plate 22;

[0038] The second fixed shaft 24 is located at one end of the inner portion of the slide slot 25, and the pressure sensor 27 is electrically connected to the power supply of the external device;

[0039] When the elastic force of the telescopic spring 26 measured by the pressure sensor 27 reaches a set value, the external power supply can be controlled to be turned off;

[0040] Working principle: When the moving part of the mechanical equipment moves to the upper end of the movable plate 22, since the movable plate 22 is in an inclined upward state, the moving part of the mechanical equipment drives the movable plate 22 to rotate downward along the first fixed axis 23, and the rotation of the movable plate 22 drives the telescopic spring 26 to be compressed. When the movable plate 22 rotates to contact the bottom end of the slide groove 25 and the bottom end of the second fixed axis 24, the movable plate 22 is fixed by the first fixed axis 23 and the second fixed axis 24, so that the movable plate 22 blocks the moving part of the mechanical equipment for the second time. At this time, the pressure sensor 27 measures that the elastic force of the telescopic spring 26 reaches the set value, and the pressure sensor 27 controls the external power supply to be turned off, so that the movement state of the moving part of the mechanical equipment can be stopped.

[0041] See also Figure 3 As shown, this embodiment is based on the above embodiment and also includes:

[0042] The limiting assembly includes a hollow groove 31 , a fixing column 32 , a fixing nut 33 , a slide rail 34 and a limiting plate 35 .

[0043] The hollow groove 31 is opened at both sides of the bottom end of the limit seat body 11, the fixing column 32 is placed inside the hollow groove 31, the fixing nut 33 is threadedly connected to the outer surface of one end of the fixing column 32, the slide rail 34 is fixedly connected to the top end of the fixing column 32, and the limit plate 35 is fixedly connected to the outer end of the slide rail 34;

[0044] The hollow groove 31 is used to place the fixing column 32, the fixing column 32 is used to support the slide rail 34, the fixing nut 33 is used to limit the fixing column 32, the slide rail 34 is used to support the limiting plate 35, and the limiting plate 35 is used to limit the moving parts of the mechanical equipment;

[0045] The outer surface of one end of the fixing column 32 has a thread structure opened relative to the fixing nut 33, and the limiting plate 35 is in an inclined inward state;

[0046] By moving the fixed column 32 in the inner position of the hollow groove 31, the slide rail 34 and the limit plate 35 can be driven to move;

[0047] Working principle: when it is necessary to limit the movement of the moving parts of the mechanical equipment, the fixing nut 33 is screwed downward so that the fixing nut 33 does not fix the fixing column 32, and then a moving force is applied to the fixing column 32 to make the fixing column 32 move along the direction of the hollow groove 31. The movement of the fixing column 32 drives the slide rail 34 and the limiting plate 35 to move. When the slide rail 34 and the limiting plate 35 move to the desired position, the fixing nut 33 is screwed upward again so that the fixing nut 33 fixes the fixing column 32. When the moving parts of the mechanical equipment move to the position of the limiting plate 35, since the spacing between the limiting plates 35 is smaller than the spacing between the slide rails 34, the moving parts of the mechanical equipment cannot move outward through the limiting plate 35, thereby realizing the limiting function, and when the limiting plate 35 is worn so that its spacing is the same as the spacing of the slide rails 34, the limiting plate 35 is moved by moving the fixing column 32 until the limiting plate 35 whose inner spacing is smaller than the spacing of the slide rails 34 moves to the desired position.
