Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, and in particular to a linear guide locking device. Background Technology

[0002] A linear guide locking device is a mechanical or hydraulic mechanism used to reliably fix a slider on a linear guide at a target position. Its core function is to prevent the slider from moving unexpectedly due to external forces or inertia when the equipment needs to be precisely positioned or stopped.

[0003] Currently, common locking devices are usually integrated into the slider body. After the slider moves the load to the predetermined position, the operator must follow the slider to that position before manually or with the aid of tools to operate the locking mechanism. This design makes the locking process dependent on the synchronous movement of the operator, which not only increases the operator's workload but also reduces the overall locking efficiency due to the time spent on movement and positioning. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a linear guide rail locking device that integrates the operation part of the locking component into one end of the guide rail component, so that the operator does not need to move with the slider, but can centrally control the slider locking from one end of the guide rail, effectively avoiding the need for personnel to follow back and forth, simplifying the operation process, and helping to improve locking efficiency.

[0006] To achieve the above objectives, the first aspect of this utility model provides a linear guide rail locking device, comprising: a guide rail assembly, a slider assembly, and a locking assembly, wherein the slider assembly is mounted on the top of the guide rail assembly, and the locking assembly includes a pressure adjusting mechanism, a blocking mechanism, and a plurality of elastic plugs, wherein the pressure adjusting mechanism is disposed at one end of the guide rail assembly, the blocking mechanism is disposed inside the guide rail assembly, and the plurality of elastic plugs are respectively disposed at the bottom of the slider assembly.

[0007] In addition, the linear guide rail locking device proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the guide rail assembly includes a fixed base, a connecting frame, and a pipe bracket, wherein the connecting frame is fixedly connected to the top of the fixed base, and the pipe bracket is fixedly connected to the top of the connecting frame.

The upper connecting plate is disposed at the top of the pipe frame, the two lower connecting plates are respectively disposed on both sides of the connecting frame, and the multiple rollers are respectively installed between the upper connecting plate and the lower connecting plate.

[0010] Specifically, the pressure regulating mechanism includes a piston tube, a piston rod, a connecting rod, and a handle. The piston tube is fixedly installed on one end of the inner side of the pipe frame. The piston rod is disposed inside the piston tube, and a piston plate is fixedly connected to one end of the piston rod. The connecting rod is fixedly connected to one end of the fixed base. The handle is slidably connected to the outside of the connecting rod, and the connecting rod is fixedly connected to the piston rod. Positioning holes are provided on the connecting rod and the handle.

[0011] Specifically, the sealing mechanism includes two movable plates and multiple sealing tubes.

[0020] The embodiments of this utility model are described in detail below. Examples of these 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. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The linear guide rail locking device of this utility model is described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown in the figure, a linear guide rail locking device according to an embodiment of the present invention includes: a guide rail assembly, a slider assembly, and a locking assembly.

[0023] The guide rail assembly includes a fixed base, a connecting bracket, and a pipe bracket.

[0024] The connecting bracket is fixedly connected to the top of the fixed base, and the pipe bracket is fixedly connected to the top of the connecting bracket.

[0025] The slider assembly is mounted on top of the guide rail assembly. The slider assembly includes an upper connecting plate, multiple rollers, and two lower connecting plates.

[0026] The upper connecting plate is located at the top of the pipe rack, and the two lower connecting plates are located on both sides of the connecting rack. Multiple rollers are installed between the upper and lower connecting plates.

[0027] The locking assembly includes a pressure regulating mechanism, a sealing mechanism, and multiple resilient plugs.

[0028] The pressure regulating mechanism is located at one end of the guide rail assembly, the sealing mechanism is located inside the guide rail assembly, and multiple elastic plugs are located at the bottom of the slider assembly.

[0029] Specifically, multiple flexible plugs are fixedly installed on the side of the two lower connecting plates near the connecting frame.

[0030] Specifically, operators can use this linear guide locking device to quickly lock the slider assembly.

[0031] The rollers of the slider assembly roll on the outside of the pipe frame, causing the upper and lower connecting plates to slide on the track assembly. The sealing mechanism of the locking assembly can seal the connecting frame to prevent the elastic plug in the lower connecting plate from being inserted into the connector.

[0032] When it is necessary to lock the slider assembly, the operator only needs to control the adjustment component to make the blocking component operate. At this time, the elastic plug on the lower connecting plate is inserted into the connecting frame to lock the slider assembly.

[0033] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the sealing mechanism includes two movable plates and multiple sealing tubes.

[0034] The two movable plates are slidably connected to the inner side of the corresponding connecting frame. Each of the two connecting frames has multiple positioning holes evenly opened on the side near the lower connecting plate. The two movable plates are fixedly connected to the corresponding protrusions that are inserted into the positioning holes on the side near the lower connecting plate.

[0035] It should be noted that the flexible plug can be stably slid into the positioning hole on the connector.

[0036] Multiple sealing tubes are fixedly installed inside the two connecting frames, and sealing shafts corresponding to the inserted sealing tubes are fixedly connected to the two movable plates.

[0037] It should be noted that the sealing shaft and the sealing tube are slidably connected, and a sealing ring is provided between the sealing shaft and the sealing tube, so that the inside of the pipe rack can always remain sealed.

[0038] The pressure regulating mechanism includes a piston tube, a piston rod, a connecting rod, and a handle.

[0039] The piston tube is fixedly installed at one end of the inner side of the pipe rack, the piston rod is located inside the piston tube, and a piston plate is fixedly connected to one end of the piston rod.

[0040] Specifically, multiple vent holes are provided on the inner side of the piston tube near the fixed base, which reduces air resistance when the piston plate slides inside the piston tube.

[0041] The connecting rod is fixedly connected to one end of the fixed base, and the handle is slidably connected to the outside of the connecting rod. The connecting rod is also fixedly connected to the piston rod, and positioning holes are provided on the connecting rod and the handle.

[0042] Specifically, there are two positioning holes on the connecting rod and the handle. By selecting different positioning holes to fix the handle, the pressure inside the locking guide frame can be adjusted.

[0043] Specifically, when the operator needs to lock the slider assembly, he only needs to remove the pin used to lock the positioning rod and the handle, and pull the handle away from the fixed base, so that the piston plate slides in the piston tube. At this time, the air pressure in the guide frame decreases, the pressure on the sealing shaft decreases, so that the supporting force of the protrusion is less than the supporting force of the elastic pin, and the elastic pin is inserted into the positioning hole on the connecting frame, thereby locking the slider assembly.

[0044] When the slider assembly needs to be unlocked, simply push the handle towards the fixed base so that the piston plate slides inside the piston tube. At this time, the air pressure inside the guide frame increases, the pressure on the sealing shaft increases, the protrusion re-inserts into the positioning hole of the connecting frame, and pushes the elastic pin out of the positioning hole. At this time, the slider assembly can move on the guide rail assembly, and the handle and positioning rod are reconnected and locked using the pin.

[0045] It should be noted that the supporting force of the flexible plug is less than the supporting force of the protrusion under high pressure inside the catheter holder.

[0046] In summary, the linear guide rail locking device of this invention, by setting the pressure regulating mechanism at one end of the guide rail, allows the operator to control the locking and releasing of the slider assembly by changing the air pressure in the pipeline through manipulation of the handle, without moving with the slider, without needing to move with the slider. This simplifies the operation process, helps improve locking efficiency in long-stroke applications, and reduces the operator's workload.
