UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a production line straight line moving workstation car, which has the effects of convenient route switching and time and labor saving.

[0006] The above technical purpose of the utility model is realized through the following technical scheme: a production line straight line moving workstation car, which comprises a car frame main body, a plurality of rollers rotatably arranged at the bottom of the car frame main body, a plurality of positioning support parts arranged on the car frame main body, a hinge seat rotatably connected to the car frame main body through a first rotating shaft, wherein the hinge seat comprises a power input part and a power output part arranged eccentrically with the first rotating shaft, a driving handle fixedly connected to the power input part, a guide rod arranged on the car frame main body and capable of being lifted and switched between a use state and a storage state, a pull rod connected between the power output part and the guide rod, one end of the pull rod being hingedly connected to the power output part, the other end of the pull rod being hingedly connected to the upper end of the guide rod, and an elastic piece arranged between the guide rod and the car frame main body and always having a tendency to move the guide rod towards the storage state.

[0007] By adopting the above technical solution, the drive handle is lifted upwards, causing the hinge seat to rotate upwards around the first pivot axis. This allows the lifting force to be transmitted from the power input end of the hinge seat to the power output end. The power output end then applies an upward pulling force to the pull rod, causing the upper end of the pull rod to rotate upwards synchronously with the hinge seat. Consequently, the pull rod lifts the guide rod relative to the frame body to the retracted state. At the same time, the elastic element provides an upward pushing assist force to the guide rod, making the upward retraction process of the guide rod easier. Similarly, pressing the drive handle downwards causes the guide rod to slide downwards into the use state. When it is necessary to switch routes, switching the guide rod to the retracted state allows it to disengage from the corresponding guide rail on the ground. Then, by pushing the frame body, the frame body can be easily moved to another route using the rollers. Pressing the drive handle downwards then causes the guide rod to re-insert into the guide rail on the corresponding route. Route switching is easy and convenient, saving effort and providing the effect of convenient route switching and time-saving and labor-saving operation.

[0008] A further feature of this invention is that the top of the guide rod is provided with a rotating connection part, one end of the pull rod near the hinge seat is rotatably connected to the power output part through a second rotating shaft, and the other end of the pull rod away from the hinge seat is rotatably connected to the rotating connection part through a third rotating shaft. When the guide rod is in use, the central axes of the guide rod and the first rotating shaft, the second rotating shaft, and the third rotating shaft are all on the same horizontal plane.

[0009] By adopting the above technical solution, when the guide rod is in use, the upward supporting force on the guide rod is directly applied to the first rotating shaft through the pull rod and the hinge seat, which improves the support stability of the guide rod in use and can effectively prevent the guide rod from accidentally switching to the storage state during its movement within the corresponding guide rail.

[0010] A further feature of this invention is that the frame body includes a mounting base, the mounting base is provided with a guide sleeve, the guide rod is guided through the guide sleeve, and the hinge seat is rotatably connected to the mounting base via the first rotating shaft.

[0011] By adopting the above technical solution, the addition of the guide sleeve allows the guide rod to move vertically up and down relative to the main body of the frame, which helps to improve the consistency of the guide rod's lifting and lowering direction.

[0012] A further feature of this invention is that a bearing is fitted onto the end of the guide rod furthest from the pull rod.

[0013] By adopting the above technical solution, the addition of bearings enables the lower end of the guide rod to roll against the inner wall of the guide rail on the corresponding route through the bearings, thereby improving the smoothness of the guide rod sliding in the corresponding guide rail and effectively reducing the noise generated when the present invention moves.

[0014] A further feature of this invention is that a baffle is fixedly provided at one end of the guide rod near the pull rod, the elastic element is sleeved on the guide rod, and the upper end of the elastic element abuts against the baffle, while the lower end of the elastic element abuts against the guide sleeve.

[0015] A further feature of this invention is that: two mounting seats are provided, the two mounting seats are symmetrically arranged on the vehicle frame body, and the drive handle includes a handle part and a connecting part, one end of the handle part is fixedly connected to the middle part of the connecting part, and both ends of the connecting part are respectively fixedly connected to the corresponding hinge seats on the two mounting seats.

[0016] By adopting the above technical solution and using multiple sets of guide rods in coordination, the consistency of the movement direction of the frame body can be improved, preventing the frame body from rotating around the guide rod when using a single guide rod. At the same time, a single drive handle can control multiple guide rods to switch synchronously between the use state and the storage state, improving the convenience of operation.

[0017] A further feature of this invention is that the frame body is provided with a crossbeam, and the mounting seat is fixedly connected to the crossbeam by fasteners.

[0018] A further feature of this invention is that the guide rod is vertically positioned in the middle of the main body of the vehicle frame.

[0019] By adopting the above technical solution, it is beneficial to balance the uniformity of the force distribution on the main body of the frame at both ends of the guide rod.

[0020] A further feature of this invention is that the mounting base is provided with at least two guide sleeves, a plurality of the guide sleeves are coaxially arranged, and the guide rod is movably inserted through the plurality of the guide sleeves.

[0021] By adopting the above technical solution, multiple guide sleeves cooperate with each other, further improving the consistency of the vertical lifting direction of the guide rod relative to the main body of the frame.

[0022] A further feature of this invention is that: a receiving groove is provided at the bottom of the guide rod, a spring and a ball are provided in the receiving groove, at least part of the ball is exposed at the opening end of the receiving groove, a push block is provided between the spring and the ball, the push block is slidably disposed in the receiving groove, the push block is provided with a rotating groove corresponding to the ball, and the spring always has a tendency to push the push block against the ball.

[0023] By adopting the above technical solution, when the bottom of the guide rod contacts the bottom of the guide rail, if the contact surface at the bottom of the guide rail is uneven, the spring can cause the ball to bounce up and down through the action of the push block, thereby ensuring that the bottom of the guide rod and the track surface always maintain rolling contact, thus reducing the risk of jamming when the main body of the frame moves.

[0024] In summary, this utility model has the following beneficial effects:

[0025] The vehicle employs a chassis with several positioning support sections. A hinge seat is rotatably connected to the chassis via a first rotating shaft. The hinge seat includes a power input section and a power output section eccentrically positioned to the first rotating shaft. A drive handle is fixedly connected to the power input section. A guide rod is also raised and lowered on the chassis, allowing it to switch between a used state and a stored state relative to the chassis. A pull rod connects the power output section and the guide rod, with one end hinged to the power output section and the other end hinged to the upper end of the guide rod. An elastic element is provided between the guide rod and the chassis. During operation, lifting the drive handle causes the hinge seat to rotate upwards around the first rotating shaft, transmitting the lifting force from the power input end to the power output end. The power output end then provides an upward force to the pull rod. The pulling force causes the upper end of the pull rod to flip upwards synchronously with the hinge seat, thereby lifting the guide rod relative to the frame body to the retracted state. At the same time, the elastic element provides an upward pushing assistance force to the guide rod, making the upward retraction process easier. Similarly, pressing down the drive handle moves the guide rod downwards to the use state. When changing routes, switching the guide rod to the retracted state disengages it from the corresponding guide rail on the ground. Then, by pushing the frame body, the rollers can be easily moved to another route. Pressing down the drive handle then inserts the guide rod back into the guide rail on the corresponding route. Route switching is easy and convenient, saving time and effort. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings. Specific Implementation Example 1

[0035] A linear motion worktable trolley for a production line, such as Figures 1-2 As shown, the vehicle includes a frame body 1, several rollers 11 rotatably mounted on the bottom of the frame body 1, several positioning support parts 12 on the frame body 1, and a hinge seat 2 rotatably connected to the frame body 1 via a first rotating shaft 20. The hinge seat 2 includes a power input part 21 and a power output part 22 eccentrically arranged with the first rotating shaft 20. A drive handle 3 is fixedly connected to the power input part 21. A guide rod 5 is also raised and lowered on the frame body 1, and the guide rod 5 can be raised and lowered relative to the frame body 1 in the use state and the storage state. The system allows for switching between lifting and lowering. A pull rod 4 connects the power output unit 22 and the guide rod 5. One end of the pull rod 4 is hinged to the power output unit 22, and the other end is hinged to the upper end of the guide rod 5. An elastic element 6 is provided between the guide rod 5 and the frame body 1. The elastic element 6 always tends to move the guide rod 5 towards the retracted state. A rotating connection part 5132 is provided at the top of the guide rod 5. The end of the pull rod 4 near the hinge seat 2 is rotatably connected to the power output unit 22 through a second rotating shaft 52, and the end of the pull rod 4 away from the hinge seat 2 is connected to... The guide rod 5 is rotatably connected to the rotating connection part 5132 via the third rotating shaft 53. When the guide rod 5 is in use, the central axes of the guide rod 5, the first rotating shaft 20, the second rotating shaft 52, and the third rotating shaft 53 are all on the same horizontal plane. When the guide rod 5 is in use, the upward supporting force on the guide rod 5 is directly applied to the first rotating shaft 20 through the pull rod 4 and the hinge seat 2, which improves the support stability of the guide rod 5 in use and can effectively prevent the guide rod 5 from accidentally switching to the storage state during movement within the corresponding guide rail. A bearing 54 is sleeved on the end of the guide rod 5 away from the pull rod 4. The addition of the bearing 54 allows the lower end of the guide rod 5 to roll and cooperate with the inner wall of the guide rail on the corresponding route through the bearing 54, improving the smoothness of the guide rod 5 sliding in the corresponding guide rail and effectively reducing the noise generated when the utility model moves. In addition, in this embodiment, a retaining rod 7 is connected between the first rotating shaft 20 and the second rotating shaft 52. The addition of the retaining rod 7 further improves the stability of the lifting and lowering movement of the guide rod 5.

[0036] like Figures 1-3 As shown, the frame body 1 includes a mounting base 13, which is provided with a guide sleeve 131. The guide rod 5 is guided and passes through the guide sleeve 131, and the hinge seat 2 is rotatably connected to the mounting base 13 via the first rotating shaft 20. The addition of the guide sleeve 131 allows the guide rod 5 to only move vertically up and down relative to the frame body 1, which helps to improve the consistency of the direction of the guide rod 5's vertical movement. A baffle 55 is fixedly provided at one end of the guide rod 5 near the pull rod 4. An elastic element 6 is sleeved on the guide rod 5, with the upper end of the elastic element 6 abutting against the baffle 55 and the lower end of the elastic element 6 abutting against the guide sleeve 131. There are two mounting bases 13, which are symmetrically arranged on the frame body 1. The drive handle 3 includes a handle part 31 and a connecting part 32. One end of the handle part 31 is fixedly connected to the middle of the connecting part 32. The two ends of the connecting part 32 are respectively fixedly connected to the corresponding hinge seats 2 on the two mounting seats 13. By using multiple sets of guide rods 5 in cooperation, the consistency of the movement direction of the frame body 1 can be improved, and the situation where the frame body 1 rotates around the guide rod 5 is prevented when using a single guide rod 5. At the same time, one drive handle 3 can control multiple guide rods 5 to switch between the use state and the storage state simultaneously, improving the convenience of operation. The frame body 1 is provided with a crossbeam 14, and the mounting seat 13 is fixedly connected to the crossbeam 14 by fasteners 141. The guide rod 5 is vertically set in the middle of the frame body 1, which is conducive to balancing the uniformity of the force distribution of the frame body 1 at both ends of the guide rod 5.

[0037] The basic working principle of this utility model is as follows: A plurality of positioning support parts 12 are provided on the frame body 1. A hinge seat 2 is rotatably connected to the frame body 1 via a first rotating shaft 20. The hinge seat 2 includes a power input part 21 and a power output part 22 eccentrically arranged with respect to the first rotating shaft 20. A drive handle 3 is fixedly connected to the power input part 21. A guide rod 5 is also raised and lowered on the frame body 1. The guide rod 5 can be raised and lowered relative to the frame body 1 between a use state and a storage state. A pull rod 4 is connected between the power output part 22 and the guide rod 5. One end of the pull rod 4 is hinged to the power output part 22, and the other end of the pull rod 4 is hinged to the upper end of the guide rod 5. An elastic element 6 is provided between the guide rod 5 and the frame body 1. During operation, by raising the drive handle 3 upward, the drive handle 3 causes the hinge seat 2 to rotate upward around the first rotating shaft 20, so that the lifting force is transmitted from the power input end of the hinge seat 2 to the power output end. At the power output end, an upward pulling force is applied to the pull rod 4, causing the upper end of the pull rod 4 to flip upward synchronously with the hinge seat 2. This causes the pull rod 4 to lift the guide rod 5 relative to the frame body 1 to a retracted state. Simultaneously, the elastic element 6 provides an upward pushing assist force to the guide rod 5, making the upward retraction process of the guide rod 5 easier. Similarly, pressing down the drive handle 3 causes the guide rod 5 to slide downward to the usable state. When it is necessary to switch routes, by switching the guide rod 5 to the retracted state, the guide rod 5 can be disengaged from the corresponding guide rail on the ground. Then, by pushing the frame body 1, the frame body 1 can be easily moved to another route using the roller 11. Pressing down the drive handle 3 causes the guide rod 5 to re-insert into the guide rail on the corresponding route. Route switching is easy and convenient, saving effort and providing the effect of convenient route switching and time-saving and labor-saving operation. Specific Implementation Example 2

[0039] A linear motion worktable trolley for a production line, such as Figures 4-6 As shown, the difference between this embodiment and specific embodiment one is that: the mounting base 13 is provided with at least two guide sleeves 131, and several guide sleeves 131 are coaxially arranged, and the guide rod 5 is movably inserted into several guide sleeves 131. The multiple guide sleeves 131 cooperate with each other, further improving the consistency of the vertical lifting direction of the guide rod 5 relative to the frame body 1; the bottom of the guide rod 5 is provided with a receiving groove 56, and a spring 561 and a ball 563 are provided in the receiving groove 56. The ball 563 is at least partially exposed at the opening end of the receiving groove 56, and the spring 561 and the ball 563 are connected. A push block 562 is provided, which is slidably disposed in the receiving groove 56. The push block 562 has a rotating groove 5621 corresponding to the ball 563. The spring 561 always has the tendency to push the push block 562 against the ball 563. When the bottom of the guide rod 5 contacts the bottom of the guide rail, if the contact surface at the bottom of the guide rail is uneven, the spring 561 can cause the ball 563 to jump up and down through the push block 562, thereby ensuring that the bottom of the guide rod 5 always maintains rolling contact with the rail surface, thereby reducing the risk of jamming when the frame body 1 moves.

[0040] The other structures of this embodiment are the same as those of Specific Embodiment 1, and will not be described again here.

[0041] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
