Description

Technical Field

[0001] This application relates to the field of non-standard equipment technology, and more specifically, to a positioning device. Background Technology

[0002] In existing technologies, when collecting information from non-standard equipment, the equipment is typically fixed to a transport trolley of compatible length. The trolley is then secured to a flat surface with screws to ensure stability and improve the accuracy of information collection. However, when collecting information from non-standard equipment of varying lengths, the transport trolley must be removed from the flat surface, replaced with a trolley of compatible length, and then secured back to the flat surface with screws. This process of replacing and securing the transport trolley is complex, resulting in low efficiency in collecting information from non-standard equipment. Summary of the Invention

[0003] The main objective of this application is to provide a positioning device to solve the problem mentioned in the background art of the complexity of operating the transport trolley for replacing and fixing non-standard equipment when collecting information on non-standard equipment of different lengths.

[0015] Furthermore, the second engaging portion includes at least two limiting holes, which are respectively disposed on the sidewalls of opposite sides of the slide groove along the second direction. The second locking component includes:

[0016] The limiting rod includes at least two rods, which are respectively installed on opposite sides of the first locking component along the second direction and penetrate the body.

[0017] The elastic limiting part includes at least two elastic limiting parts, which are respectively disposed on opposite sides of the mounting groove along the second direction and abut against the limiting block. The limiting rod can be at least partially engaged in the limiting hole or disengaged from the limiting hole under the elastic force of the elastic limiting part.

[0018] Furthermore, the limiting block includes a first mounting block and a second mounting block interconnected along a third direction, and the elastic limiting part includes:

[0019] A first elastic element is disposed between the inner wall surface of the mounting groove on one side along the second direction and the first mounting block;

[0020] The second elastic element is disposed between the inner wall surface of the mounting groove on the other side along the second direction and the second mounting block.

[0021] Furthermore, a fixing structure is provided between the limiting block and the limiting rod. The limiting rod includes a first limiting rod and a second limiting rod. The fixing structure includes a first fixing groove, a second fixing groove, and at least two fasteners. The first fixing groove and the second fixing groove are respectively provided on opposite sides of the limiting block along the second direction. At least one of the fasteners passes through one side of the first mounting block along the third direction and abuts against one end of the first limiting rod located in the first fixing groove. At least one of the fasteners passes through the other side of the second mounting block along the third direction and abuts against one end of the second limiting rod located in the second fixing groove.

[0022] Furthermore, the limiting block includes a first mounting block and a second mounting block that are connected to each other. The first mounting block and the second mounting block are each provided with a first groove on the side closest to each other. The first groove of the first mounting block and the first groove of the second mounting block constitute the limiting groove.

[0023] Furthermore, a chamfered surface is provided between the inner wall surface of the limiting groove and the side of the limiting block near the limiting protrusion, and a limiting surface parallel to the chamfered surface is provided on the side of the limiting protrusion near the chamfered surface.

[0024] Furthermore, the rod body is provided with connecting grooves on both opposite sides along the second direction, and at least a portion of the rod body located in the connecting groove passes through the limiting groove.

[0026] In this application, the transport component is detachably installed in the groove of the limiting component and can reciprocate along a first direction. A locking component locks the transport component in a first position (the position where information can be collected from the non-standard equipment). The locking component easily locks the transport component to the limiting component, preventing the transport component from shaking and affecting the stability of the non-standard equipment, ensuring the stability of the non-standard equipment fixed to the transport component, and improving the accuracy of information collection from the non-standard equipment. The locking component can also unlock the transport component to a second position (away from the position where information is collected from the non-standard equipment) to replace the non-standard equipment or replace it with a transport component of a length compatible with the non-standard equipment to be collected. When collecting information from non-standard equipment of different lengths, the transport component can be detached from the groove simply by sliding it away from the stop block. After replacing it with a transport component of a length compatible with the non-standard equipment, the replaced transport component is installed in the groove, and when the transport component is moved to the first position abutting against the stop block, the locking component locks it in the first position. The operation of changing transport components is simpler, reducing the time required and improving the efficiency of information collection from non-standard equipment. Furthermore, this positioning device is applicable to transport components of varying lengths and can detect non-standard equipment of different lengths, making it more versatile and flexible.

Detailed Implementation

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0043] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0044] When collecting information from non-standard equipment, the equipment is typically fixed to a transport trolley of compatible length, and then the trolley is secured to a flat surface with screws to ensure stability and improve the accuracy of information collection. However, when collecting information from non-standard equipment of varying lengths, the transport trolley must be removed from the flat surface, replaced with a trolley of compatible length, and then secured back to the flat surface with screws. This process of replacing and securing the transport trolley is complex, resulting in low efficiency in collecting information from non-standard equipment.

[0045] To address the aforementioned technical problems, this embodiment provides a positioning device, such as... Figures 1 to 11 As shown, the positioning device includes a limiting member 1, a transport member 2, and a locking member 3. The limiting member 1 is provided with a sliding groove 11. The length of the sliding groove 11 extends along a first direction, and a stop block 12 is provided at one end of the sliding groove 11 along the first direction. The transport member 2 is detachably installed within the sliding groove 11 and can reciprocate along the first direction. The transport member 2 has a first position where it moves to abut against the stop block 12, and a second position away from the stop block 12. The transport member 2 is used at least for installing non-standard equipment. The locking member 3 is detachably installed between the limiting member 1 and the transport member 2 and is located on the side of the transport member 2 away from the stop block 12. The locking member 3 locks the transport member 2 in the first position or unlocks it to the second position.

[0046] In this embodiment, the transport component 2 is detachably installed in the slide groove 11 of the limiting component 1 and can move along the first direction (e.g., Figure 1The transport component 2 moves back and forth in the direction indicated by arrow X (specifically, the length direction of the slide 11). When the transport component 2 slides along the first direction to abut against the stop block 12, the locking component 3 locks the transport component 2 in the first position abutting against the stop block 12 (this first position is the position where information can be collected from the non-standard equipment). The locking component 3 can easily lock and fix the transport component 2 to the limiting component 1, preventing the transport component 2 from shaking and affecting the stability of the non-standard equipment, ensuring that the non-standard equipment fixed on the transport component 2 remains stable, which is conducive to improving the accuracy of information collection from the non-standard equipment. There is no need for manual fixing of the transport component 2 with screws, etc., which is simple to operate and saves time and effort.

[0047] When the locking member 3 performs the unlocking operation, disengaging the connection between the transport member 2 and the limiting member 1, the transport member 2 can slide to a second position away from the stop block 12. This second position allows for the replacement of non-standard equipment or the replacement of a transport member 2 of a length suitable for the non-standard equipment to be collected. When collecting information from non-standard equipment of different lengths, simply sliding the transport member 2 removes it from the slide groove 11. After replacing it with a transport member 2 of the appropriate length, the replaced transport member 2 is then installed back into the slide groove 11. This simplifies the replacement of the transport member 2, reduces the operation time, and improves the efficiency of information collection from non-standard equipment. Furthermore, this positioning device is applicable to transport members 2 of different lengths and can detect non-standard equipment of varying lengths. This positioning device has a wider range of applications and greater versatility and flexibility.

[0048] Therefore, compared with the existing technology that uses screws to fix the transport component 2, this embodiment uses locking component 3 to lock the transport component 2 in the first position and unlock it to the second position, which is simpler and faster, and has higher efficiency in collecting information from non-standard equipment.

[0049] It is understandable that the transport component 2 can also be used to install other equipment besides non-standard equipment for information collection, and this embodiment does not limit it to a single device.

[0050] In one embodiment, the transport member 2 has a first engaging portion on the side near the locking member 3. The limiting member 1 has a second engaging portion. The locking member 3 includes a body 31, a first locking component, and a second locking component. The body 31 is detachably mounted in the slide groove 11 and can reciprocate along a first direction. The first locking component is mounted on the body 31 and detachably engaged with the first engaging portion. The second locking component is mounted on the body 31 and connected to the first locking component. The second locking component has a locking position where it engages with the second engaging portion under external force and an unlocking position where it is separated from the second engaging portion. The engagement of the first locking component with the first engaging portion achieves stable force transmission. When the external force drives the first locking component to move along the first direction, the force is transmitted to the transport member 2 through the first locking component and the first engaging portion, driving the transport member 2 to move to the first position where it abuts against or moves away from the stop block 12. The first locking component is detachably fastened to the first engaging part, which also facilitates quick and convenient disassembly and installation of the transport component 2, thereby improving the efficiency of information collection from non-standard equipment.

[0051] When the transport component 2 is in the first position, the second locking component, under external force, engages with the second engaging part, locking the transport component 2 in the first position. When the second locking component is in the unlocked position, the connection between the transport component 2 and the limiting component 1 is released, allowing the transport component 2 to move away from the stop block 12 for replacing non-standard equipment or transport components 2 of another size. By controlling the external force, the second locking component can switch between the locked and unlocked positions to control the transport component 2 to be locked in the first position or unlocked to the second position, facilitating faster locking and unlocking of the transport component 2. In addition, by observing the state of the second locking component, it is possible to clearly and intuitively determine whether the transport component 2 is locked, which helps to further ensure the stability of the transport component 2 and reduce information collection errors caused by operational mistakes. The body 31 provides support for the first and second locking components, ensuring their reliability.

[0052] like Figures 3 to 10 As shown, in one embodiment, the first engaging portion includes a engaging groove 21. A mounting groove 311 is provided within the body 31. The first locking component includes a limiting block 321 and a push-pull rod 322. The limiting block 321 is installed within the mounting groove 311, meaning the mounting groove 311 accommodates the limiting block 321, limiting and fixing it to prevent loosening and ensuring stable installation within the mounting groove 311.

[0053] A limiting groove 3217 is provided through the limiting block 321 along a first direction. The push-pull rod 322 includes a rod body 3221, a pulling part 3222, a limiting protrusion 3223, and a locking connector 3224. The rod body 3221 passes through the body 31 along the first direction and is at least partially inserted into the limiting groove 3217. The pulling part 3222 and the locking connector 3224 are located at opposite ends of the rod body 3221 and outside the body 31, respectively. When the operator applies external force to push or pull the pulling part 3222, the external force can be transmitted along the rod body 3221 to the locking connector 3224.

[0054] The snap-fit ​​connector 3224 is inserted into the snap-fit ​​groove 21 and can move and abut against the side wall of the snap-fit ​​groove 21 along the first direction, so as to realize the stable connection between the transport component 2 and the locking component 3, and ensure that the force on the snap-fit ​​connector 3224 is stably transmitted to the snap-fit ​​groove 21 and drives the transport component 2 to move back and forth with the push-pull rod 322.

[0055] The limiting protrusions 3223 include at least two, which are spaced apart along a first direction between the pulling part 3222 and the snap-fit ​​connector 3224 and located on opposite sides of the limiting groove 3217 along the first direction. The distance between the at least two limiting protrusions 3223 along the first direction is greater than the length of the limiting groove 3217 along the first direction, so that the push-pull rod 322 can move relative to the limiting block 321 along the first direction without disengaging from the limiting block 321. When the snap-fit ​​connector 3224 is inserted into the snap-fit ​​groove 21 on the transport component 2, if it is necessary to move the transport component 2 toward the stop block 12 to lock the transport component 2 in the first position by the second locking component, the push-pull rod 322 is pushed so that the snap-fit ​​connector 3224 abuts against the side wall of the snap-fit ​​groove 21 away from the body 31 in the first direction (at this time, the limit block 321 abuts against the limit protrusion 3223 on the rod body 3221 near the pulling part 3222), so that the transport component 2 can move to abut against the stop block 12 under the pushing action of the push-pull rod 322. If it is necessary to remove the transport component 2 from the slide 11, when the connection between the transport component 2 and the limiting component 1 is released by the second locking component to move the transport component 2 to the second position, the push rod 322 is pulled away from the stop block 12 so that the snap connector 3224 abuts against the side wall of the snap groove 21 along the first direction near the body 31 (at this time, the limiting block 321 abuts against the limiting protrusion 3223 on the push rod 322 near the snap connector 3224), so that the snap connector 3224 can drive the transport component 2 to move away from the stop block 12 to the second position. When it is necessary to replace the transport component 2, the snap connector 3224 can be separated from the snap groove 21 to separate the first locking component from the transport component 2.

[0056] Specifically, the snap-fit ​​groove 21 is a T-shaped groove structure provided on the surface of the transport component 2 near the body 31. The T-shaped groove includes an open section 211 and a snap-fit ​​section 212 that are interconnected. The size of the snap-fit ​​connector 3224 is smaller than the size of the snap-fit ​​section 212 and larger than the size of the open section 211, so that the snap-fit ​​connector 3224 can move relative to the snap-fit ​​section 212 and abut against the two side walls of the snap-fit ​​section 212 along the first direction. One end of the rod 3221 near the snap-fit ​​connector 3224 is adapted to the open section 211. When the snap-fit ​​connector 3224 is located inside the snap-fit ​​section 212, the end of the rod 3221 near the snap-fit ​​connector 3224 rests inside the open section 211. When it is necessary to separate the snap-fit ​​connector 3224 from the snap-fit ​​section 212, the rod 3221 is lifted to separate the snap-fit ​​connector 3224 from the snap-fit ​​section 212.

[0057] The limiting groove 3217 can fix the rod 3221 in the limiting block 321. At least two limiting protrusions 3223 are spaced apart along the first direction between the pulling part 3222 and the snap connector 3224 and located on opposite sides of the limiting groove 3217 along the first direction. The at least two limiting protrusions 3223 can restrict the movement of the limiting member 1, so that the limiting block 321 can reciprocate along the first direction with the rod 3221. A cover plate 3112 can be provided on the mounting groove 3111 to seal the mounting groove 3111.

[0058] like Figures 1 to 10 As shown, in one embodiment, the second engaging portion includes a limiting hole 13, and the limiting hole 13 includes at least two holes, along the second direction (e.g., Figure 1 The direction indicated by arrow Y (the second direction is perpendicular to the first direction, specifically the width direction of the limiting member 1) is shown in the figure. At least two limiting holes 13 are respectively provided on the side walls of opposite sides of the slide groove 11. The second locking component includes limiting rods 331 and elastic limiting parts. The limiting rods 331 include at least two rods, which are respectively installed on opposite sides of the first locking component along the second direction and pass through the body 31. The elastic limiting parts include at least two parts, which are respectively provided in the mounting groove 311 on opposite sides along the second direction and abut against the limiting block 312. The limiting rods 331 can be at least partially engaged in the limiting holes 13 or disengaged from the limiting holes under the action of elastic force. The at least two limiting rods 331 are respectively installed on opposite sides of the first locking component along the second direction and pass through the body 31, fixing the limiting rods 331 on the first locking component. When the first locking component is pushed or pulled by external force, the limiting rods 331 move back and forth with the first locking component along the first direction. When the transport component 2 is in the first position, the limiting rod 331 is engaged in the limiting hole 13 under the elastic force of the elastic limiting part, locking the transport component 2 in the first position. When the transport component 2 leaves the first position, the limiting rod 331 disengages from the limiting hole 13 under the elastic force of the elastic limiting part, allowing the transport component 2 to move to the second position.

[0059] Among them, the limiting block 321 includes a third direction (such as...) Figure 1 The direction indicated by arrow Z (the third direction is perpendicular to both the first and second directions, specifically the height direction of the limiting member 1) connects the first mounting block 3214 and the second mounting block 3215. The elastic limiting part includes a first elastic member and a second elastic member. The first elastic member is disposed between the inner wall surface of the mounting groove 311 along the second direction and the first mounting block 3214. The second elastic member is disposed between the inner wall surface of the mounting groove 311 along the other side of the second direction and the second mounting block 3215. A ball bearing 332 is disposed on the side of the limiting rod 331 away from the first locking member along the second direction. Specifically, when the transport member 2 moves to the first position along the first direction, it pushes the pulling part 3222, and the first and second elastic members are in a compressed state and have a tendency to extend. The first and second elastic members cause the first mounting block 3214 and the second mounting block 3215 to have a tendency to move away from the rod 3221. When the transport component 2 moves to the first position, the first and second elastic elements extend and retract, causing the limiting rod 331 to engage within the limiting hole 13, thus maintaining the transport component 2 in the first position and preventing it from sliding, ensuring the stability of the transport component 2. When the transport component 2 leaves the first position, the ball bearing 332 is compressed by the wall of the limiting hole 13, causing the first and second elastic elements to contract. The ball bearing 332 disengages from the limiting hole 13, thereby causing the limiting rod 331 to disengage from the limiting hole 13 under the elastic force of the elastic limiting part.

[0060] The limiting rod 331 can automatically engage with or disengage from the limiting hole 13, so that the second locking component is locked in the first position or unlocked to the second position. During this process, there is no need for manual locking or unlocking. The operator only needs to apply a pushing or pulling force to quickly lock or unlock the transport component 2, which greatly simplifies the fixing operation of the transport component 2 and improves the information collection efficiency of non-standard equipment.

[0061] In this device, multiple limiting holes 13 are respectively provided on the side walls of opposite sides of the slide 11, and the multiple limiting holes are spaced apart along the first direction on the side walls so that the distance between the limiting holes 13 at different positions on the side walls of the slide 11 and the stop block 12 matches the length of the transport component 2. When using transport components 2 of different lengths, the limiting rod 332 can be engaged into the limiting hole 13 to lock the transport component 2 in the first position, which can be applied to transport components 2 of various specifications, thus expanding the applicability of the positioning device. It is understood that the elastic element can be a spring, but it is not limited to this, and this embodiment does not make it the only limitation.

[0062] In one embodiment, a fixing structure is provided between the limiting block 321 and the limiting rod 331. The limiting rod 331 includes a first limiting rod 3311 and a second limiting rod 3312. The fixing structure includes a first fixing groove 3211, a second fixing groove 3212, and at least two fasteners 3213. The first fixing groove 3211 and the second fixing groove 3212 are respectively disposed on opposite sides of the limiting block 321 along a second direction. At least one fastener 3213 is disposed through one side of the first mounting block 3214 along a third direction and abuts against one end of the first limiting rod 3311 located in the first fixing groove 3211, and at least one fastener 3213 is disposed through one side of the first mounting block 3215 along a third direction (e.g., ...). Figure 1 The direction indicated by arrow Z in the diagram is perpendicular to both the first and second directions (specifically, the height direction of the limiting member 1) on the other side and abuts against one end of the second limiting rod 3312 located in the second fixing groove 3212. Fastener 3213 secures the first limiting rod 3311 and the second limiting rod 3312 respectively within the first fixing groove 3211 and the second fixing groove 3212, ensuring that the limiting rod 331 is stably fixed to the limiting block 321, enhancing the connection strength between the limiting block 321 and the limiting rod 331, and effectively preventing the limiting rod 331 from loosening. It also facilitates the assembly and disassembly of the limiting block 321 and the limiting rod 331. The first fixing groove 3211 and the second fixing groove 3212 enable the limiting rod 331 to be quickly and accurately positioned during installation, improving the installation efficiency of the limiting rod 331. Furthermore, since the fasteners 3213 connecting the first limiting rod 3311 and the second limiting rod 3312 are located on opposite sides of the limiting block 321 along a third direction, it avoids opening holes on the same side of the limiting block 321 for fastener 3213 fixation, thus reducing the structural strength of the limiting block 321.

[0063] like Figure 11 As shown, in one embodiment, the limiting block 321 includes a first mounting block 3214 and a second mounting block 3215 connected to each other. Both the first mounting block 3214 and the second mounting block 3215 have a first groove 3216 on their sides closest to each other. The first groove 3216 of the first mounting block 3214 and the first groove 3216 of the second mounting block 3215 form a limiting groove 3217. A push-pull rod 322 is installed in the first groove 3216, providing installation guidance for the push-pull rod 322 and ensuring accurate installation of the push-pull rod 322. The first mounting block 3214 and the second mounting block 3215 are connected to form the limiting block 321, making the structure of the limiting block 321 more compact, which is beneficial to improving the integration of the positioning device and facilitating quick installation of the push-pull rod 322 and the limiting rod 331. Specifically, the first mounting block 3214 and the second mounting block 3215 have the same structure.

[0064] In one embodiment, a chamfered surface 3218 is provided between the inner wall surface of the limiting groove 3217 and the side of the limiting block 321 near the limiting protrusion 3223. A limiting surface 3225 parallel to the chamfered surface 3218 is provided on the side of the limiting protrusion 3223 near the chamfered surface 3218. The chamfered surface 3218 abuts against the limiting surface 3225, increasing the contact area between the limiting protrusion 3223 and the limiting groove 3217, which helps to disperse stress, reduce local stress concentration, ensure that the chamfered surface 3218 is subjected to uniform force, and drive the limiting block 321 to move with the push-pull rod 322, thus ensuring the stability of the limiting block 321 during movement.

[0065] In one embodiment, the rod 3221 has connecting grooves 3226 on both opposite sides along the second direction. At least a portion of the rod 3221 located in the connecting grooves 3226 passes through a limiting groove 3217. A limiting protrusion 3223 is the portion of the rod 3221 offset from the connecting grooves 3226, and a limiting surface 3225 is located on the sidewall of the limiting protrusion 3223 near the connecting grooves 3226. With at least a portion of the rod 3221 passing through the limiting grooves 3217, the rod 3221 can be quickly and accurately positioned to a predetermined location during installation, improving installation efficiency. Simultaneously, the limiting protrusions 3223 on both opposite sides of the connecting grooves 3226 along the first direction limit the rod 3221 within the limiting grooves 3217, ensuring the stability of the rod 3221. In this embodiment, the limiting protrusion 3223 is processed by opening a connecting groove 3226 on the rod body 3221, which is efficient and convenient.

[0066] In one embodiment, the stop block 12 protrudes from the bottom of the slide groove 11. A locking notch 121 is provided on the side of the stop block 12 near the transport component 2, and a locking boss 22, adapted to the locking notch 121, is provided on the side of the transport component 2 near the stop block 12. The locking boss 22 cooperates with the locking notch 121 to ensure the precise positioning of the transport component 2 within the slide groove 11, so that the transport component 2 is in a first position, preventing the transport component 2 from shifting or shaking and affecting the accuracy of information collection. Specifically, the locking protrusion is located on at least one side of the transport component 2 along a first direction and extends out of the transport component 2. The locking protrusion is close to the bottom of the slide groove 11, and the outer wall surface of the locking protrusion abuts against the inner wall surface of the locking notch 121.

[0067] like Figure 11As shown, in one embodiment, the inner wall of the slide groove 11 is further provided with a first slide rail 111, a second slide rail 112, and a third slide rail 113. The first slide rail 111 and the second slide rail 112 are located on opposite sides of the limiting member 1 along the second direction, with the first slide rail 111 located on the upper side of the second slide rail 112 away from the bottom of the slide groove 11. The third slide rail 113 is located on both sides of the bottom of the slide groove 11 along the second direction. The limiting hole 13 is located inside the first slide rail 111, so that the ball 332 connected to the end of the limiting rod 331 of the second locking member can be engaged in or disengaged from the limiting hole 13 during the reciprocating movement along the first slide rail 111. The first slide rail 111 limits the movement trajectory of the ball 332 as it moves with the locking member 3, preventing the ball 332 from disengaging from the first slide rail 111 and thus making it difficult for the ball 332 to engage with the limiting hole 13. This ensures that when the transport member 2 moves to the first position, the ball 332 can smoothly enter the limiting hole 13 to lock the transport member 2 in the first position. Furthermore, the friction generated by the ball 332 during its movement along the first slide rail 111 is relatively small, making the sliding of the ball 332 within the first slide rail 111 smoother. The bottom and sides of the transport member 2 near the bottom of the groove 11 are equipped with pulleys. The pulleys on the sides of the transport member 2 are located within the second slide rail 112, and the pulleys on the bottom of the transport member 2 are located within the third slide rail 113, allowing the transport member 2 to reciprocate along the first direction.

[0068] Along the first direction, a guide surface 114 is also provided at the end of the limiting member 1 away from the stop block 12. Specifically, the guide surface 114 is located at the starting end of the first slide rail 111 and / or the second slide rail 112 away from the stop block 12, and the guide surface 114 is inclined in the second direction away from the third slide rail 113 to expand the sliding space at the starting end of the first slide rail 111 and / or the second slide rail 112. As a result, the pulley on the side of the transport member 2 can slide more accurately and conveniently into the second slide rail 112 along the guide surface 114, and / or the limiting rod 331 of the locking member 3 can also drive the ball 332 at its end to slide more accurately and conveniently into the first slide rail 111 along the guide surface 114, improving the accuracy and convenience of the transport member 2 and the locking member 3 sliding into the slide groove 11.

[0069] The present invention adopts a modular design for the transport component 2, locking component 3, and limiting component 1, which makes it easier to assemble and disassemble the positioning device, and also makes it easier to maintain and replace some parts.

[0070] like Figures 1 to 11As shown, in this embodiment, along the first direction, the locking member 3224 on the locking member 3 engages with the locking groove 21 on the transport member 2, forming a flexible connection between the locking member 3 and the transport member 2. Then, the flexibly connected locking member 3 and transport member 2 are placed in the slide groove 11, pushing the push-pull rod 322 to move horizontally along the first direction. The limiting surface 3225 on the push-pull rod 322 near the slide groove 11 engages with the chamfered surface 3218 on the second mounting block 3215, and the limiting surface 3225 on the push-pull rod 322 away from the slide groove 11 engages with the chamfered surface 3218 on the first mounting block 3214. The push-pull rod 322 drives the limiting rod 331 to move along the first direction. The pulley on the side of the transport member 2 moves within the second slide rail 112, and the pulley on the bottom of the transport member 2 moves within the third slide rail 113. The ball bearing 332 slides into the first slide rail 111 via the guide surface 114. When the engaging boss 22 on the transport component 2 engages with the engaging notch 121 on the stop block 12, the transport component 2 moves into position. At this time, the limiting rod 331 falls into the limiting hole 13 on the first slide rail 111, and the conical surface at the connection between the limiting rod 331 and the ball 332 weds tightly with the limiting hole 13. Under the action of the stop block 12 and the locking component 3, the transport component 2 is clamped and positioned on the limiting component 1. The opposite occurs when the transport component is pulled horizontally in the first direction.

[0071] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0072] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0073] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
