Abstract
Description
Technical Field
[0001] This utility model relates to the field of cabinet positioning accessories, and more specifically, to a cabinet pin positioning device. Background Technology
[0002] Currently, most server racks on the market use hinges or hinges to connect the cabinet doors to the cabinet body. In daily use and maintenance, technicians and users need to frequently open and close the cabinet doors. In order to prevent the cabinet doors from swinging randomly due to accidental collisions when opened, or even hitting adjacent equipment or walls, it is necessary to effectively position or limit the opening angle of the cabinet doors when they are open for a long time.
[0003] However, some cabinet door opening angle limiters on the market have relatively complex structures, such as using cylinders to limit the opening angle of the cabinet door. The production cost of this type of cabinet door opening angle limiter is relatively high, and it needs to be lubricated regularly during use, which also results in high maintenance costs.
[0004] Some simple cabinet door opening angle limiters, such as those that use a locking pin that is manually controlled to extend or retract, can only open the cabinet door to a certain angle before manually controlling the pin to descend and position the door. While these door opening angle limiters are simple in structure and low in cost, they cannot automatically control the opening angle of the cabinet door. They require manual opening of the door to a suitable angle before controlling the locking pin to extend and fix the door. This makes the cabinet appear relatively low-end overall.
[0005] Therefore, it is necessary to propose a cabinet pin positioning device to solve the above problems. Utility Model Content
[0006] To overcome at least one of the defects (deficiencies) of the prior art described above, this utility model provides a cabinet pin positioning device.
[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a cabinet pin positioning device, comprising a positioning mounting base, a positioning pin, a return spring and a positioner;
[0008] The positioning mounting base is provided with a first positioning post and a second positioning post respectively. The positioning pin is provided with a positioning hole, a first pin connecting strip hole and a second pin connecting strip hole respectively. A pin separator plate is provided between the first pin connecting strip hole and the second pin connecting strip hole.
[0009] The positioning pin is sleeved inside the positioning mounting base, and the first positioning post on the positioning mounting base passes through the first pin through the connecting strip hole, and the second positioning post on the positioning mounting base passes through the second pin through the connecting strip hole.
[0010] The two ends of the return spring are respectively disposed on the first positioning post and the pin separator plate;
[0011] The locator is mounted on the positioning mounting base. When the positioning pin extends from the bottom of the positioning mounting base, the locator passes through the positioning hole on the positioning pin. When the positioning pin is pulled up, the locator passes through the first pin connecting slot on the positioning pin. By fitting the positioning pin onto the positioning mounting base, and with the first positioning post on the positioning mounting base passing through the first pin connecting slot on the positioning pin, and the second positioning post on the positioning mounting base passing through the second pin connecting slot on the positioning pin, the positioning pin can reciprocate on the positioning mounting base as needed. In the normal state of the positioning pin, the return spring allows the end of the positioning pin to extend out of the positioning mounting base. When the positioning pin is pulled upward, it compresses the return spring, causing the end of the positioning pin to retract into the interior of the positioning mounting base. The locator, based on the state of the positioning pin in the positioning mounting base, passes through the positioning hole or the first pin connecting slot on the positioning pin, thereby restricting the state of the positioning pin in the positioning mounting base.
[0012] Furthermore, the positioner includes a positioning seat, a positioning locking pin, a locking pin return spring, a locking pin handle, and a limiting protrusion;
[0013] The positioning seat is mounted on the positioning mounting base, and the positioning seat is provided with a limiting inner groove and a through hole for the positioning locking pin to pass through;
[0014] The locking pin handle is located at the end of the positioning locking pin, the limiting protrusion is located at the front end of the positioning locking pin, the positioning locking pin return spring is sleeved on the positioning locking pin, one end of the positioning locking pin return spring abuts against the locking pin handle, and the other end is pressed against the positioning seat.
[0015] When the positioning locking pin passes through the through hole and is engaged in the first pin connecting strip hole or the positioning card hole, the locking pin handle is flipped and placed in the limiting inner groove, and the limiting protrusion abuts against the edge of the positioning card hole or the first pin connecting strip hole.
[0016] The locking pin handle is connected to a pull ring. Since the positioning seat is set on the positioning mounting seat, and the positioning seat has a limiting inner groove and a through hole for the positioning locking pin to pass through, after the positioning locking pin passes through the through hole on the positioning seat, it will pass through the first pin connecting strip hole or positioning card hole on the positioning pin again according to the state of the positioning pin on the positioning mounting seat, thereby locking the state of the positioning pin. The limiting protrusion can abut against the edge of the first pin connecting strip hole or positioning card hole after the positioning locking pin is rotated, thereby fastening it at the edge of the first pin connecting strip hole or positioning card hole. After the positioning locking pin is rotated, the locking pin handle can be locked in the limiting inner groove of the positioning seat. When the locking pin handle is locked in the limiting inner groove, the locking pin handle can be pulled open by the pull ring, which facilitates the separation of the locking pin handle from the limiting inner groove, thereby adjusting the positioning state.
[0017] Furthermore, the positioning hole is provided with a keyway through hole and a first keyway engaging slot, and the first pin connecting strip hole is provided with a second keyway engaging slot. When the front end of the positioning locking pin passes through the positioning hole, the limiting protrusion on the positioning locking pin passes through the keyway through hole. When the locking pin handle is flipped and placed in the limiting inner groove, the limiting protrusion on the positioning locking pin is engaged in the first keyway engaging slot of the positioning hole after flipping. When the front end of the positioning locking pin passes through the first pin connecting strip hole, the limiting protrusion on the positioning locking pin passes through the first pin connecting strip hole. When the locking pin handle is flipped... When the pin is rotated and placed in the limiting groove, the limiting protrusion on the positioning pin is engaged in the second keyway engaging slot of the first pin connecting strip hole after being rotated. The keyway through hole facilitates the passage of the limiting protrusion at the front end of the positioning pin. Since the length of the first pin connecting strip hole is relatively long, the limiting protrusion at the front end of the positioning pin can pass through smoothly. The first keyway engaging slot on the positioning hole and the second keyway engaging slot on the first pin connecting strip hole facilitate the mutual engaging of the limiting protrusion at the front end of the positioning pin after being rotated, thereby realizing the fixation of the positioning pin by the positioning device.
[0018] Furthermore, a limiting strip is provided on the positioning mounting base between the first positioning post and the second positioning post. By setting the limiting strip, the movable width of the left and right sides of the return spring can be narrowed, thereby reducing the amplitude of the return spring swinging to the left and right sides during compression.
[0019] Furthermore, there are two limiting strips, which are symmetrically arranged. In practical applications, the number of limiting strips can be set as needed, and these are all alternative solutions that are easy for those skilled in the art to conceive of.
[0020] Furthermore, both the first positioning post and the pin partition plate are provided with limiting posts. One end of the return spring is connected to the limiting post on the first positioning post, and the other end of the return spring is connected to the limiting post on the pin partition plate. By providing limiting posts on both the first positioning post and the pin partition plate, the two ends of the return spring can be fixed, preventing the return spring from shifting during compression or stretching. This is simple and practical.
[0021] Furthermore, the first positioning post and the limiting post are integrated into one piece, and the pin separator and the limiting post are integrated into one piece. This integrated structure effectively simplifies the overall structure of the cabinet pin positioning device.
[0022] Furthermore, the positioning mounting base includes a first positioning mounting base component and a second positioning mounting base component;
[0023] The first segment of the positioning mounting base is provided with a positioning retaining ring, and the first positioning post and the second positioning post are both provided on the second segment of the positioning mounting base. When the second segment of the positioning mounting base is welded to the first segment of the positioning mounting base, the first positioning post and the second positioning post are respectively pressed against the positioning retaining ring on the first segment of the positioning mounting base. Since the positioning mounting base is composed of the first segment and the second segment of the positioning mounting base fixedly connected to each other, it is convenient to install the positioning pin. In practical applications, the first segment and the second segment of the positioning mounting base can be installed and fixed by welding or clamping. Since the first segment of the positioning mounting base is provided with a positioning retaining ring, the first positioning post and the second positioning post can be easily installed on the positioning retaining ring of the first segment of the positioning mounting base.
[0024] Furthermore, the positioning pin is provided with a pull rope hole. With the pull rope hole, a pull rope can be tied to the pull rope hole during use, so as to make it easy to lift the positioning pin by pulling the rope.
[0025] Furthermore, the positioning mounting base, positioning pin, positioner, first positioning post, second positioning post, and pin separator are all made of alloy material. In practical applications, the positioning mounting base, positioning pin, positioner, first positioning post, second positioning post, and pin separator can also be made of other materials, which are all alternative solutions that are easy for those skilled in the art to conceive of.
[0026] Compared with the prior art, the beneficial effects of this utility model's technical solution are:
[0027] The cabinet pin positioning device disclosed in this utility model involves fitting a positioning pin onto a positioning mounting base. A first positioning pin on the positioning mounting base passes through a first pin-connecting slot on the positioning pin, and a second positioning pin on the positioning mounting base passes through a second pin-connecting slot on the positioning pin. Therefore, the positioning pin can reciprocate on the positioning mounting base as needed. In the normal state of the positioning pin, a return spring allows the end of the positioning pin to extend out of the positioning mounting base. When the positioning pin is pulled upwards, it compresses the return spring, causing the end of the positioning pin to retract into the positioning mounting base. The positioner, based on the state of the positioning pin in the positioning mounting base, passes through a positioning locking hole or a first pin-connecting slot on the positioning pin, thereby restricting the state of the positioning pin in the positioning mounting base.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0039] like Figure 1-2As shown, a cabinet pin positioning device includes a positioning mounting base 1, a positioning pin 2, a return spring 3, and a positioner 4. The positioning mounting base 1 is provided with a first positioning post 5 and a second positioning post 6. The positioning pin 2 is provided with a positioning locking hole 7, a first pin connecting strip hole 8, and a second pin connecting strip hole 9. A pin separator 10 is provided between the first pin connecting strip hole 8 and the second pin connecting strip hole 9. The positioning pin 2 is sleeved inside the positioning mounting base 1. The first positioning post 5 on the positioning mounting base 1 passes through the first pin connecting strip hole 8, and the second positioning post 6 on the positioning mounting base 1 passes through the second pin connecting strip hole 9. The two ends of the return spring 3 are respectively located on the first positioning post 5 and the pin separator 10. The positioner 4 is located on the positioning mounting base 1. When the positioning pin 2 extends out from the bottom of the positioning mounting base 1, the positioner 4 passes through the positioning locking hole 7 on the positioning pin 2. When the positioning pin 2 is pulled up... The positioner 4 passes through the first pin-connecting slot 8 on the positioning pin 2. By fitting the positioning pin 2 onto the positioning mounting base 1, and with the first positioning post 5 on the positioning mounting base 1 passing through the first pin-connecting slot 8 on the positioning pin 2, and the second positioning post 6 on the positioning mounting base 1 passing through the second pin-connecting slot 9 on the positioning pin 2, the positioning pin 2 can reciprocate on the positioning mounting base 1 as needed. In the normal state of the positioning pin 2, the return spring 3 can extend the end of the positioning pin 2 out of the positioning mounting base 1. When the positioning pin 2 is pulled upward, it will compress the return spring 3, at which time the end of the positioning pin 2 will retract into the interior of the positioning mounting base 1. The positioner 4 then passes through the positioning locking hole 7 or the first pin-connecting slot 8 on the positioning pin 2 according to the state of the positioning pin 2 in the positioning mounting base 1, thereby restricting the state of the positioning pin 2 in the positioning mounting base 1.
[0040] like Figure 3-6As shown, the positioner 4 includes a positioning seat 11, a positioning locking pin 12, a locking pin return spring 13, a locking pin handle 14, and a limiting protrusion 15. The positioning seat 11 is mounted on the positioning mounting base 1, and the positioning seat 11 has a limiting inner groove 16 and a through hole 17 for the positioning locking pin 12 to pass through. The locking pin handle 14 is located at the end of the positioning locking pin 12, the limiting protrusion 15 is located at the front end of the positioning locking pin 12, and the positioning locking pin return spring 13 is sleeved on the positioning locking pin 12. One end of the positioning locking pin return spring 13 abuts against the locking pin handle 14, and the other end is pressed against the positioning seat 11. When the positioning locking pin 12 passes through the through hole 17 and is engaged in the first pin connecting strip hole 8 or the positioning card hole 7, the locking pin handle 14 flips over and is positioned in the limiting inner groove 16. The limiting protrusion 15 abuts against the edge of the positioning card hole 7 or the first pin connecting strip hole 8. A pull ring 18 is connected to the locking pin handle 14. Since the positioning seat 11 is mounted on the positioning mounting base... The positioning base 11 is provided with a limiting inner groove 16 and a through hole 17 for the positioning locking pin 12 to pass through. Therefore, after the positioning locking pin 12 passes through the through hole 17 on the positioning base 11, it will pass through the first pin connecting strip hole 8 or the positioning card hole 7 on the positioning pin 2 again according to the state of the positioning pin 2 on the positioning mounting base 1, thereby locking the state of the positioning pin 2. The limiting protrusion 15 can abut against the edge of the first pin connecting strip hole 8 or the positioning card hole 7 after the positioning locking pin 12 is rotated, thereby fastening it at the edge of the first pin connecting strip hole 8 or the positioning card hole 7. After the positioning locking pin 12 is rotated, the locking pin handle 14 can be locked in the limiting inner groove 16 of the positioning base 11. When the locking pin handle 14 is locked in the limiting inner groove 16, the locking pin handle 14 can be pulled open by the pull ring 18, so that the locking pin handle 14 can be separated from the limiting inner groove 16, thereby adjusting the positioning state.
[0041] In this utility model, a keyway through hole 19 and a first keyway engaging groove 20 are provided on the positioning hole 7, and a second keyway engaging groove 21 is provided on the first pin connecting strip hole 8. When the front end of the positioning locking pin 12 passes through the positioning hole 7, the limiting protrusion 15 on the positioning locking pin 12 passes through the keyway through hole 19. When the locking pin handle 14 is flipped and placed in the limiting inner groove 16, the limiting protrusion 15 on the positioning locking pin 12 is engaged in the first keyway engaging groove 20 of the positioning hole 7 after flipping. When the front end of the positioning locking pin 12 passes through the first pin connecting strip hole 8, the limiting protrusion 15 on the positioning locking pin 12 passes through the first pin connecting strip hole 8. When the locking pin handle 14 is flipped and placed in the limiting inner groove 16, the limiting protrusion 15 on the positioning locking pin 12 is engaged in the first keyway engaging groove 20 of the positioning hole 7 after flipping. When placed in the limiting groove 16, the limiting protrusion 15 on the positioning locking pin 12 is engaged in the second keyway engaging groove 21 of the first pin connecting strip hole 8 after being flipped. The setting of the keyway through hole 19 facilitates the passage of the limiting protrusion 15 at the front end of the positioning locking pin 12. Since the length of the first pin connecting strip hole 8 is relatively long, the limiting protrusion 15 at the front end of the positioning locking pin 12 can pass through smoothly. The first keyway engaging groove 20 on the positioning hole 7 and the second keyway engaging groove 21 on the first pin connecting strip hole 8 facilitate the mutual engaging of the limiting protrusion 15 at the front end of the positioning locking pin 12 after being flipped, thereby realizing the fixation of the positioning pin 2 by the positioning device 4.
[0042] In this utility model, a limiting strip 22 is provided on the positioning mounting base 1 between the first positioning post 5 and the second positioning post 6. By setting the limiting strip 22, the movable width of the left and right sides of the return spring 3 can be narrowed, thereby reducing the amplitude of the return spring 3 swinging to the left and right sides during compression. There are two limiting strips 22, symmetrically arranged. In practical applications, the number of limiting strips 22 can be set as needed; these are all alternative solutions easily conceived by those skilled in the art. Limiting posts 23 are provided on both the first positioning post 5 and the pin separator 10, and the return spring... One end of the spring 3 is connected to the limiting post 23 on the first positioning post 5, and the other end of the return spring 3 is connected to the limiting post 23 on the pin partition plate 10. By providing limiting posts 23 on both the first positioning post 5 and the pin partition plate 10, both ends of the return spring 3 can be fixed, preventing the return spring 3 from shifting during compression or stretching. This is simple and practical. In this utility model, the first positioning post 5 and the limiting post 23 are an integral structure, and the pin partition plate 10 and the limiting post are an integral structure. The integral structure can effectively simplify the overall structure of the cabinet pin positioning device.
[0043] like Figure 7-8As shown, the positioning mounting base 1 includes a first positioning mounting base 24 and a second positioning mounting base 25. The first positioning mounting base 24 is provided with a positioning retaining ring 26. A first positioning post 5 and a second positioning post 6 are both disposed on the second positioning mounting base 25. When the second positioning mounting base 25 is welded to the first positioning mounting base 24, the first positioning post 5 and the second positioning post 6 respectively press against the positioning retaining ring 26 on the first positioning mounting base 24. Since the positioning mounting base 1 is fixedly connected by the first positioning mounting base 24 and the second positioning mounting base 25... The components are connected in a way that facilitates the installation of the positioning pin 2. In practical applications, the first part 24 and the second part 25 of the positioning mounting base can be installed and fixed by welding or clamping. Since the first part 24 of the positioning mounting base is provided with a positioning retaining ring 26, the first positioning post 5 and the second positioning post 6 can be easily installed on the positioning retaining ring 26 of the first part 24 of the positioning mounting base. In practical applications, the positioner 4 can be set in the first part 24 or the second part 25 of the positioning mounting base as needed, and their functions are the same.
[0044] The positioning pin 2 is provided with a pull rope hole 27. The pull rope hole 27 allows a pull rope to be tied to it during use, making it easy to lift the positioning pin 2 by pulling the rope. In this utility model, the positioning mounting base 1, positioning pin 2, positioning device 4, first positioning post 5, second positioning post 6, and pin partition plate 10 are all made of alloy material. In practical applications, the positioning mounting base 1, positioning pin 2, positioning device 4, first positioning post 5, second positioning post 6, and pin partition plate 10 can also be made of other materials, which are all alternative solutions that are easy for those skilled in the art to conceive of.
[0045] Example
[0046] In use, the positioning mounting base is placed on the cabinet door, and mounting holes are provided at the bottom of the cabinet. Because the bottom of the cabinet exerts a pressing force on the positioning pin, the positioning pin retracts into the positioning mounting base. When the positioning pin on the cabinet door rotates to the mounting hole at the bottom of the cabinet, the end of the positioning pin extends and locks into the mounting hole. At this time, in order to achieve secondary locking, the locator can be controlled to pass through the positioning locking hole on the positioning pin, so that the positioning pin is locked. To unlock, the locator must be unlocked first, and then the positioning pin is pulled up so that the cabinet door can be driven to rotate again.
[0047] When it is not necessary to limit the opening angle of the cabinet door, the positioning pin can be pulled up. At this time, the end of the positioning pin is flush with the bottom of the positioning mounting base or hidden inside the positioning mounting base. When the positioning pin is pulled up, the positioner passes through the first pin connecting strip hole on the positioning pin, thereby positioning the positioning pin in the positioning mounting base. In addition, since the positioning base is set on the positioning mounting base, and the positioning base is provided with a limiting inner groove and a through hole for the positioning locking pin to pass through, after the positioning locking pin passes through the through hole, it can rotate and lock into the limiting inner groove of the positioning base. The limiting protrusion at the front end of the positioning locking pin can abut against the edge of the first pin connecting strip hole or the positioning locking hole after the positioning locking pin rotates, thereby fastening it at the edge of the first pin connecting strip hole or the positioning locking hole. In this utility model, a pull ring is connected to the locking pin handle. When the locking pin handle is locked in the limiting inner groove, the locking pin handle can be pulled open by the pull ring, which facilitates the separation of the locking pin handle from the limiting inner groove, thereby adjusting the positioning state.
[0048] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting this patent. Clearly, the above embodiments of this utility model are merely examples to clearly illustrate the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
