Description

Technical Field

[0001] The present application relates to the technical field of safety gratings, and in particular to a grating adjustment fixture. Background Art

[0002] In modern factories, humans and machines work together, and in potentially dangerous operating environments, such as those involving mold processing and metal cutting equipment, personal injury to operators is a common occurrence. Safety light barriers are an advanced technology used to protect operators around various hazardous mechanical equipment. By placing a pair of safety light barriers on either side of the danger zone's boundary, with one side providing the light-emitting side and the other the light-receiving side, when a person or obstruction attempts to cross the danger zone's boundary, blocking the infrared light path, the light-receiving side cannot receive normal light signals. At this point, the light barrier indicator turns off, and the operating system stops functioning, reducing the risk of injury to operators from mechanical equipment.

[0003] In actual operation, due to the influence of the operating environment or the vibration generated by the equipment during operation, the alignment of the two sides of the safety grating will deviate, causing the safety grating to malfunction. When the two sides of the safety grating deviate, the maintenance engineer needs to return the grating to its original position. The current method of resetting the safety grating mostly relies on manual bending to return it to its original position.

[0004] The above-mentioned existing technical solutions have the following defects: the grating is generally installed in a groove and is fixed relatively tightly, making it difficult to bend. During adjustment, the grating installation groove is relatively narrow, making manual adjustment inconvenient. Utility Model Content

[0005] In order to facilitate the staff to reset the grating and shorten the time of grating reset, the present application provides a grating adjustment fixture.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] The grating adjustment fixture includes a fixing rod, one end of which is fixedly connected to a first clamping block, a second clamping block is sleeved on the fixing rod, the second clamping block slides on the fixing rod, a first slider is formed on the second clamping block, a through hole is opened on the fixing rod, the first slider is embedded in and slides in the through hole, an outer wall of the fixing rod is processed to form an external thread, the external thread is a one-side thread and the thread is a quarter turn, a fixing sleeve is sleeved on the fixing rod, and the inner wall of the fixing sleeve is processed to form an internal thread that matches the external thread.

[0008] By adopting the above technical solution, the fixing sleeve is rotated to move the external thread away from the internal thread, so that the fixing sleeve can slide on the peripheral wall of the fixing rod, and the fixing sleeve is pulled to drive the second clamping block to move along the length direction of the fixing rod to a position away from the first clamping block, which is convenient for the staff to set the clamp sleeve on the peripheral wall of the grating bar to be adjusted. The first slider can ensure the smooth sliding of the second clamping block on the fixing rod, while keeping the second clamping block opposite to the first clamping block, which is convenient for the staff to clamp the clamp on the peripheral wall of the grating bar to be adjusted, and the staff to reset the grating, thereby shortening the time for resetting the grating.

[0009] Optionally, a limiting ring is provided on the peripheral wall of the fixing rod, one side of the limiting ring is fixed to the second clamping block, and the other side is rotatably connected to one end of the fixing sleeve. A limiting slider is formed on the limiting ring, and the limiting slider is embedded in and slides in the through hole. An elastic part is provided in the fixing rod, and one end of the elastic part abuts against the limiting slider.

[0010] By adopting the above technical solution, the elastic part can push the limit ring to drive the second clamping block to move toward the first clamping block, making it convenient for the staff to clamp the clamp on the peripheral wall of the grating bar to be adjusted, and convenient for the staff to move the position of the safety grating by pulling the fixing rod. The limit slider can increase the stability of the limit ring in moving on the fixing rod, ensure the accurate cooperation between the limit block and the limit groove, and facilitate the staff to use the clamp.

[0011] Optionally, a mounting block is formed on the first clamping block, and a laser line projector is installed on the mounting block.

[0012] By adopting the above technical solution, the staff can move the grating bar to be adjusted by pulling the fixed rod. At the same time, the light emitted by the laser projector will indicate the direction of the transmitter or receiver of the grating bar to be adjusted, which is convenient for the staff to reset the grating and shortens the time for grating reset.

[0013] Optionally, the laser line projector is detachably connected to the mounting block.

[0014] By adopting the above technical solution, it is convenient for the staff to adjust the direction of the light emitted by the laser line projector according to the fixture and the position of the grating to be adjusted, and it is also convenient for the staff to disassemble and maintain the laser line projector.

[0015] Optionally, a limiting groove is formed on the limiting ring, and a limiting block that matches the limiting groove is formed on the fixing sleeve, and the limiting block slides in the limiting groove.

[0016] By adopting the above technical solution, the limit block rotates in the limit groove, which can ensure the accurate matching of the internal thread and the external thread. At the same time, it is convenient for the staff to check the matching status of the internal thread and the external thread, and it is convenient for the staff to use the clamp to adjust the position of the grating bar to be adjusted.

[0017] Optionally, silicone pads are bonded to the opposite sides of the first clamping block and the second clamping block.

[0018] By adopting the above technical solution, the friction between the first clamping block and the second clamping block and the grating bar to be adjusted can be increased, ensuring that the clamp can firmly clamp the grating bar to be adjusted, while reducing the risk of damaging the grating bar when the first clamping block and the second clamping block clamp the grating bar to be adjusted, making it easier for staff to reset the grating.

[0019] Optionally, one end of the first clamping block and the second clamping block are both processed to form a bending portion, and the bending directions of the two bending portions are the same.

[0020] By adopting the above technical solution, the stability of the clamp in clamping the grating strip to be adjusted can be increased, ensuring that the clamp can firmly clamp the grating strip when the grating strip is moved by the moving clamp, making it easier for the staff to reset the grating.

[0021] Optionally, anti-slip grooves are formed on the fixing sleeve.

[0022] By adopting the above technical solution, the friction force when the staff holds the fixing sleeve can be increased, which makes it easier for the staff to rotate the fixing sleeve and use the clamp.

[0023] In summary, this application has the following technical effects:

[0024] 1. The provision of a fixing rod, a fixing sleeve, an external thread, and an internal thread facilitates the worker to place the clamp sleeve on the peripheral wall of the grating strip to be adjusted, facilitates the worker to clamp and fix the clamp on the peripheral wall of the grating strip to be adjusted, facilitates the worker to move the position of the safety grating by pulling the fixing rod, facilitates the worker to reset the grating, and shortens the grating reset time;

[0025] 2. By setting up a laser line projector, the staff can move the grating strip to be adjusted by pulling the fixed rod.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below with reference to the accompanying drawings.

[0032] The embodiment of the present application discloses a grating adjustment fixture, referring to Figure 1 and Figure 2 The clamp includes a fixing rod 1, a first clamping block 2 is welded to one end of the fixing rod 1, and a mounting block 21 is formed on the top surface of the first clamping block 2. Two mounting blocks 21 are arranged at intervals along the length direction of the first clamping block 2, and a laser line projector 4 is commonly clamped on the two first clamping blocks 2. A through hole 11 is opened at a section of the fixing rod 1 away from the first clamping block 2. The through hole 11 is opened along the length direction of the fixing rod 1 to the end of the fixing rod 1 away from the first clamping block 2, and a second clamping block 3 is sleeved on a section of the fixing rod 1 with the through hole 11. Silicone pads 5 are bonded to the opposite sides of the first clamping block 2 and the second clamping block 3. The ends of the first clamping block 2 and the second clamping block 3 away from the fixing rod 1 are both processed to form bending portions, and the bending directions of the bending portions of the first clamping block 2 and the second clamping block 3 are the same.

[0033] Reference Figure 2 and Figure 3 The second clamping block 3 is processed and formed with a first slider 31 that cooperates with the through hole 11. The first slider 31 is provided with two and is respectively embedded in and slides in the hole openings at both ends of the through hole 11. A section of the fixed rod 1 with a through hole 11 is provided with a limiting ring 6. The limiting ring 6 is located on the side of the second clamping block 3 away from the first clamping block 2 and is welded to the side wall of the second clamping block 3. A limiting slider 61 that cooperates with the through hole 11 is processed and formed on the limiting ring 6. The limiting slider 61 is provided with two and is respectively embedded in and slides in the hole openings at both ends of the through hole 11. An elastic member 7 is provided in the fixed rod 1. In this embodiment, the elastic member 7 is a spring. The elastic member 7 is located between the limiting slider 61 and the end of the fixed rod 1 away from the first clamping block 2.

[0034] Reference Figure 2 and Figure 3The fixing rod 1 is provided with a through hole 11 and a section is processed to form an external thread 12. The external thread 12 is a one-side thread and the thread is a quarter turn. The external thread 12 is arranged at intervals of two sections along the circumferential wall of the fixing rod 1. The fixing rod 1 is provided with a through hole 11 and a circumferential wall of a section is provided with a fixing sleeve 8. One end of the fixing sleeve 8 close to the limiting ring 6 is rotatably connected to the side of the limiting ring 6 close to the fixing sleeve 8. The outer wall of the fixing sleeve 8 is processed to form anti-slip grooves 81, and the inner wall of the fixing sleeve 8 is processed to form an internal thread 82 that cooperates with the external thread 12. The internal thread 82 is arranged at intervals of two sections along the inner wall of the fixing sleeve 8 and corresponds one to one with the external thread 12. The limiting ring 6 is provided with an arc-shaped limiting groove 62 toward the side of the fixing sleeve 8. The fixing sleeve 8 is processed to form a limiting block 83 at one end close to the limiting ring 6, and the limiting block 83 is slidably set in the limiting groove 62.

[0035] When using this clamp, rotate the fixing sleeve 8 to make the external thread 12 away from the internal thread 82, so that the fixing sleeve 8 can slide on the peripheral wall of the fixing rod 1, and pull the fixing sleeve 8 to drive the second clamping block 3 to move along the length direction of the fixing rod 1 away from the first clamping block 2, so that the staff can set the clamp sleeve on the peripheral wall of the grating bar to be adjusted, and then push the fixing sleeve 8 to drive the second clamping block 3 to move along the fixing rod 1 toward the first clamping block 2. The first slider 31 can ensure that the second clamping block 3 slides smoothly on the fixing rod 1, while keeping the second clamping block 3 and the first clamping block 2 facing each other. The elastic member 7 can push the limiting ring 6 to drive the second clamping block 3 to move toward the first clamping block 2, so that the staff can clamp the clamp tightly on the peripheral wall of the grating bar to be adjusted, and the staff can move the position of the safety grating by pulling the fixing rod 1.

[0036] When the second clamping block 3 and the first clamping block 2 respectively abut against the two side walls of the grating strip to be adjusted, the fixing sleeve 8 is rotated to make the external thread 12 cooperate with the internal thread 82. The anti-slip groove 81 on the outer wall of the fixing sleeve 8 can increase the friction when the staff holds the fixing sleeve 8, which is convenient for the staff to rotate the fixing sleeve 8 and convenient for the staff to use the clamp. The rotation of the external thread 12 and the internal thread 82 will push the fixing sleeve 8 and the second clamping block 3 to move in the direction of the first clamping block 2, so that the first clamping block 2 and the second clamping block 3 respectively clamp the side walls of the grating strip to be adjusted. At this time, the limit block 83 rotates in the limit groove 62, which can ensure that the internal thread 82 and the external thread 12 are accurately matched. At the same time, it is convenient for the staff to check the matching state of the internal thread 82 and the external thread 12, so that the staff can use the clamp to adjust the position of the grating strip to be adjusted. The limit slider 61 can increase the stability of the limit ring 6 moving on the fixing rod 1, ensure that the limit block 83 and the limit groove 62 are accurately matched, and it is convenient for the staff to use the clamp.

[0037] After blocking the transmitter or receiver of another fixed grating bar, turn on the laser line projector 4. The light emitted by the laser line projector 4 will illuminate the ground and the vicinity of the fixed grating bar. The staff will move the grating bar to be adjusted by pulling the fixed rod 1. At the same time, the light emitted by the laser line projector 4 will indicate the direction of the transmitter or receiver of the grating bar to be adjusted, which is convenient for the staff to reset the grating and shortens the time for resetting the grating.

[0038] The laser line projector 4 is clamped on the mounting block 21 , which makes it easy for the staff to adjust the direction of the light emitted by the laser line projector 4 according to the fixture and the grating position to be adjusted, and also makes it easy for the staff to disassemble and maintain the laser line projector 4 .

[0039] The silicone pad 5 can increase the friction between the first clamp 2 and the second clamp 3 and the grating bar to be adjusted, ensuring that the clamp can firmly clamp the grating bar to be adjusted, while reducing the risk of damaging the grating bar when the first clamp 2 and the second clamp 3 clamp the grating bar to be adjusted, making it easier for the staff to reset the grating.

[0040] The bent portions of the first clamping block 2 and the second clamping block 3 can increase the stability of the clamp in clamping the grating strip to be adjusted, ensuring that the clamp can firmly clamp the grating strip when the grating strip is moved by moving the clamp, making it easier for the staff to reset the grating.

[0041] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
