Description

Technical Field

[0001] The utility model relates to the technical field of slide rails, in particular to a linear slide rail positioning mechanism. Background Art

[0002] Slide rails, also known as guide rails and slideways, refer to hardware connection components fixed to the cabinet of furniture for the movement of drawers or cabinet panels of furniture in and out. They are suitable for drawer connections of wooden and steel drawers such as cabinets, furniture, document cabinets, bathroom cabinets, etc., and usually include linear slide rails.

[0003] In the application of slide rails, there are various ways to position the slider, such as spring-type positioning, positioning block positioning, etc. Spring-type positioning cannot achieve the expected positioning effect, cannot guarantee the accuracy of the positioning point, and the spring is easily damaged and needs to be replaced frequently. Positioning with a positioning block can only position the slider at a fixed point, and cannot position the slider in real time according to demand, which has obvious defects.

[0004] In the prior art, a Chinese patent with a publication number of CN205298266U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a linear slide positioning mechanism, including a slider, provided with a U-shaped groove opening downward, baffles on both sides of the U-shaped groove, threaded holes and slots are opened on the baffle of the slider, the threaded holes are connected to the slots, and the slider is installed on the linear slide through the U-shaped groove; a pair of locking blocks, one end of the locking block is clamped in the slot, and the other end fits the linear slide; a pair of locking screws, one end of the locking screw is threadedly connected to the threaded hole; a pair of locking wrenches, each of which is connected to one of the locking screws. The linear slide positioning mechanism of the utility model can quickly and conveniently perform real-time positioning of the running mechanism through the slide rail and the positioning mechanism, has a simple structure, is difficult to damage, has low cost, and is easy to use, but there is also a problem that the user needs to manually perform the positioning operation every time the positioning is performed, thereby increasing the user's workload. Utility Model Content

[0005] The purpose of the utility model is to provide a linear slide rail positioning mechanism to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A linear slide positioning mechanism comprises a slide body; a slider is arranged on the periphery of the slide body, connecting rods are fixedly installed inside the sliders at both ends of the slide body, a fixed block is fixedly connected to the bottom of the connecting rod at one end of the slide body, a rotating wheel is rotatably installed on the inner side of the fixed block through a torque speed sensor, the rotating wheel is rollingly connected to the slide body, a first positioning sleeve is fixedly installed inside the slider at the top of the slide body, a second positioning sleeve is fixedly connected inside the slider at the bottom of the slide body, a box is fixedly installed on one end of the slider, the box and the first positioning sleeve are fixedly connected through an upper shunt pipe, and the box and the second The positioning sleeves are fixedly connected by a lower shunt pipe, one end of a slider on one side of the box body is fixedly connected to a controller, a first partition is fixedly installed inside the slider, a second partition is fixedly connected inside the box body at one end of the first partition, a piston plate is slidably installed between the first partition and the second partition, an electric push rod is fixedly installed at one end of the slider, the electric push rod passes through the box body and is fixedly connected to the top of the piston plate, a baffle is slidably installed inside the box body through a first spring, the baffle is fitted with the other end of the first partition, and a clamping plate is slidably installed at one end of the second partition through a second spring, the clamping plate is fitted with the inner wall of the box body.

[0008] By installing a controller, the electric push rod and the torque speed sensor can be controlled, so that the user can use the device conveniently. By installing a torque speed sensor, the speed of the rotating wheel can be detected. When the slider slides on the periphery of the slide rail body, the torque speed sensor detects that the rotating wheel rotates with the slider. After the slider stops sliding, the torque speed sensor detects that the speed of the rotating wheel is zero, and transmits the detection result to the controller. The controller controls the electric push rod to contract, driving the piston plate to move upward, and at the same time generating suction on the card plate and the baffle, so that the card plate and the box body are close to each other. The inner walls are separated, so that external air can be drawn into the interior of the box body, and the electric push rod then drives the piston plate to move downward, and at the same time generates thrust on the card plate and the baffle, so that the card plate fits against the inner wall of the box body again, and the baffle is separated from the first partition, so that air can enter the interior of the first positioning sleeve through the upper diverter pipe, and the air can enter the interior of the second positioning sleeve through the lower diverter pipe. The above actions are repeated many times, so that the first positioning sleeve and the second positioning sleeve can continue to expand until they are completely fitted with the top and bottom of the slide rail body, and the slider is positioned on the periphery of the slide rail body.

[0009] A further improvement of the technical solution of the utility model is that a first anti-slip strip is attached to the bottom of the first positioning sleeve, and the first anti-slip strip is tightly fitted with the top of the slide rail body.

[0010] By adopting the above technical solution, in this solution, the friction between the first positioning sleeve and the slide rail body can be increased by installing the first anti-slip strip, thereby improving the anti-slip effect and the positioning effect of the slider on the periphery of the slide rail body.

[0011] A further improvement of the technical solution of the utility model is that a second anti-slip strip is attached to the bottom of the second positioning sleeve, and the second anti-slip strip is tightly fitted with the bottom of the slide rail body.

[0012] By adopting the above technical solution, in this solution, the friction between the second positioning sleeve and the slide rail body can be increased by installing the second anti-slip strip, thereby improving the anti-slip effect and the positioning effect of the slider on the periphery of the slide rail body.

[0013] A further improvement of the technical solution of the utility model is that both the first positioning sleeve and the second positioning sleeve are made of elastic material.

[0014] The above technical solution is adopted. In this solution, by using elastic materials for the first positioning sleeve and the second positioning sleeve, the first positioning sleeve and the second positioning sleeve can be easily expanded and contracted, thereby facilitating the positioning of the slider and the slide rail body, and facilitating the slider to slide around the periphery of the slide rail body.

[0015] A further improvement of the technical solution of the utility model is that a plurality of rollers are fixedly connected to the top and bottom of the connecting rods on both sides of the fixed block, and each roller is rollingly connected to the slide rail body.

[0016] The above technical solution is adopted. In this solution, the contact area between the connecting rod and the slide rail body can be reduced by installing a roller. At the same time, the roller can roll relative to the slide rail body, thereby reducing the wear between the slide rail body and the connecting rod and extending the service life of the slide rail body and the connecting rod.

[0017] A further improvement of the technical solution of the utility model is that a plurality of limit blocks are fixedly installed on the top and bottom of the baffle, and each limit block is slidably connected to the inside of the box.

[0018] The above technical solution is adopted. In this solution, the sliding track of the baffle plate inside the box body can be guided and limited by installing the limit block, thereby ensuring that the baffle plate can maintain linear movement.

[0019] A further improvement of the technical solution of the utility model is that a plurality of card blocks are fixedly installed on the top and bottom of the card plate, and each card block is slidably connected to the inside of the box.

[0020] The above technical solution is adopted. In this solution, the sliding track of the card plate inside the box body can be guided and limited by installing the card block, thereby ensuring that the card plate can maintain linear movement.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a linear slide positioning mechanism. When the slider stops sliding, the torque speed sensor can detect that the speed of the rotating wheel is zero, and the controller can control the electric push rod to drive the piston plate to move upward and downward, so that the external air can be sucked into the interior of the box body, and the air enters the interior of the first positioning sleeve and the second positioning sleeve through the upper shunt pipe and the lower shunt pipe respectively. After repeating the above actions for many times, the first positioning sleeve and the second positioning sleeve can be continuously expanded and completely fit the surface of the slide body, thereby realizing automatic positioning of the slider on the periphery of the slide body.

[0023] 2. The utility model provides a linear slide rail positioning mechanism, which can improve the anti-slip effect by installing a first anti-slip strip and a second anti-slip strip, and further improve the positioning effect of the slider on the periphery of the slide rail body.

They are fixedly connected by a lower shunt pipe 7, one end of a slider 1 on one side of the box body 3 is fixedly connected to a controller 4, a first partition plate 301 is fixedly installed inside the slider 1, a second partition plate 302 is fixedly connected inside the box body 3 at one end of the first partition plate 301, a piston plate 501 is slidably installed between the first partition plate 301 and the second partition plate 302, an electric push rod 5 is fixedly installed at one end of the slider 1, the electric push rod 5 passes through the box body 3 and is fixedly connected to the top of the piston plate 501, a baffle 12 is slidably installed inside the box body 3 through a first spring 1201, the baffle 12 is fitted with the other end of the first partition plate 301, a clamping plate 13 is slidably installed on one end of the second partition plate 302 through a second spring 1301, and the clamping plate 13 is fitted with the inner wall of the box body 3.

[0037] In this embodiment, the controller 4 is installed to control the electric push rod 5 and the torque speed sensor 11, so that the user can use the device conveniently. The torque speed sensor 11 is installed to detect the rotation speed of the rotating wheel 1001. When the slider 1 slides on the periphery of the slide rail body 2, the torque speed sensor 11 detects that the rotating wheel 1001 rotates with the slider 1. After the slider 1 stops sliding, the torque speed sensor 11 detects that the rotation speed of the rotating wheel 1001 is zero, and transmits the detection result to the controller 4.

The above actions are repeated many times, so that the first positioning sleeve 6 and the second positioning sleeve 14 can continue to expand until they are completely fitted with the top and bottom of the slide rail body 2, and the slider 1 is positioned on the periphery of the slide rail body 2.

[0038] Example 2

[0039] like Figure 2 and Figure 4 As shown, based on Example 1, the utility model provides a technical solution: preferably, a first anti-slip strip 601 is attached to the bottom of the first positioning sleeve 6, and the first anti-slip strip 601 fits tightly with the top of the slide rail body 2, and a second anti-slip strip 1401 is attached to the bottom of the second positioning sleeve 14, and the second anti-slip strip 1401 fits tightly with the bottom of the slide rail body 2, and the first positioning sleeve 6 and the second positioning sleeve 14 are both made of elastic material.

By using elastic materials for the first positioning sleeve 6 and the second positioning sleeve 14, the first positioning sleeve 6 and the second positioning sleeve 14 can be easily expanded and contracted, thereby facilitating the positioning of the slider 1 and the slide rail body 2 and facilitating the sliding of the slider 1 on the periphery of the slide rail body 2.

[0041] Example 3

[0042] like Figure 2 and Figure 3 As shown, based on Example 1, the utility model provides a technical solution: preferably, a plurality of rollers 901 are fixedly connected to the top and bottom of the connecting rods 9 on both sides of the fixed block 10, and each roller 901 is rollingly connected to the slide rail body 2.

[0043] In this embodiment, by installing the roller 901, the contact area between the connecting rod 9 and the slide rail body 2 can be reduced. At the same time, the roller 901 can roll relative to the slide rail body 2, thereby reducing the wear between the slide rail body 2 and the connecting rod 9 and extending the service life of the slide rail body 2 and the connecting rod 9.

[0044] Example 4

[0045] like Figure 2 and Figure 5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a plurality of limit blocks 1202 are fixedly installed on the top and bottom of the baffle 12, and each limit block 1202 is slidably connected to the inside of the box body 3; a plurality of card blocks 1302 are fixedly installed on the top and bottom of the card plate 13, and each card block 1302 is slidably connected to the inside of the box body 3.

[0046] In this embodiment, by installing the limit block 1202, the sliding trajectory of the baffle 12 inside the box body 3 can be guided and limited, thereby ensuring that the baffle 12 can maintain linear movement. By installing the card block 1302, the sliding trajectory of the card plate 13 inside the box body 3 can be guided and limited, thereby ensuring that the card plate 13 can maintain linear movement.

[0047] The following is a detailed description of the working principle of the linear slide positioning mechanism.

[0048] like Figure 1-Figure 6As shown, when the slider 1 slides on the periphery of the slide rail body 2, the torque speed sensor 11 detects that the wheel 1001 rotates with the slider 1, and the electric push rod 5 will not be triggered. After the slider 1 stops sliding, the torque speed sensor 11 detects that the speed of the wheel 1001 is zero, and the controller 4 controls the electric push rod 5 to drive the piston plate 501 to move upward, so that the card plate 13 is separated from the inner wall of the box body 3, thereby sucking external air into the interior of the box body 3, and then using the electric push rod 5 to drive the piston plate 501 to move downward, so that The clamping plate 13 is again fitted with the inner wall of the box body 3, and at the same time the baffle 12 is separated from the first partition plate 301, so that the air enters the interior of the first positioning sleeve 6 through the upper diversion pipe 8, and at the same time the air enters the interior of the second positioning sleeve 14 through the lower diversion pipe 7. After the electric push rod 5 drives the piston plate 501 to move up and down multiple times, the first positioning sleeve 6 and the second positioning sleeve 14 can continue to expand until they are completely fitted with the top and bottom of the slide rail body 2, thereby realizing automatic positioning of the slider 1 on the periphery of the slide rail body 2.

[0049] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
