Description

Technical Field

[0001] This invention relates to a chassis, and more specifically, to a cubic oxygen generator with a stable braking chassis. Background Technology

[0002] Cubic oxygen concentrators are widely used in public or semi-public environments such as community health service centers, community elderly care institutions, and rehabilitation stations. They typically need to be moved frequently between treatment rooms, observation rooms, rehabilitation activity areas, and different functional rooms to serve multiple patients or elderly people. Due to the large flow of people and varying ground conditions in community settings, oxygen concentrators need to maintain stability for extended periods during oxygen supply operations to prevent accidental displacement caused by personnel collisions, slight ground tilts, cable pulling, or equipment vibrations. This places higher demands on the mobility and braking reliability of the chassis.

[0003] Currently, most common mobile chassis use casters. After the equipment is moved into place, the operator usually only locks the casters or relies on a single support to contact the ground. This makes the chassis prone to slipping or deflection when subjected to external impacts or vibrations in the community public environment, affecting the continuity of oxygen supply and the safety of use.

[0004] Some improvement solutions involve installing a liftable brake plate under the chassis to increase friction by contacting the ground. However, after the brake plate is lowered, it is prone to rebound due to equipment vibration, accidental contact by personnel, or ground reaction force, lacking reliable mechanical locking. At the same time, the existing structure's brake plate lifting, wheel axle locking, and other actions often require separate operation or lack linkage, making it easy to make mistakes in the operation sequence, making it difficult to form multiple stable braking, and also unable to guarantee that the braking state can be maintained for a long time in the variable environment of the community. Summary of the Invention

[0005] The purpose of this invention is to provide a cubic oxygen generator with a stable braking and walking chassis to solve the problems mentioned in the background art.

[0006] To address the above problems, the present invention aims to provide a cubic oxygen concentrator with a stable braking and walking chassis, comprising an oxygen concentrator unit, two omnidirectional wheels and two directional wheels, which are respectively fixedly installed at the four corners of the lower surface of the oxygen concentrator unit. A connecting shaft is coaxially fixed between the two directional wheels. A beam plate, a U-shaped frame and a brake plate are sequentially arranged below the oxygen concentrator unit. The beam plate is horizontally slidably installed on the lower surface of the oxygen concentrator unit via a slide rail slider structure. Two clamping mechanisms are provided at the end of the beam plate near the connecting shaft. A lifting mechanism for driving the brake plate to move vertically is provided at the bottom of the beam plate. Four limiting mechanisms for locking the position of the brake plate are provided on the outer wall of the U-shaped frame. When the U-shaped frame moves horizontally away from the connecting shaft, the U-shaped frame drives the beam plate to move synchronously, thereby causing the beam plate to drive the clamping mechanism and the lifting mechanism to move. The clamping mechanism clamps and fixes the connecting shaft, and the lifting mechanism drives the brake plate to move downward. When the brake plate moves to the lower position, the limiting mechanisms restrict the brake plate from moving upward.

[0007] As a further improvement to this technical solution, the U-shaped frame is horizontally slidably installed on the oxygen generator equipment through several U-shaped guide frames. The U-shaped frame is provided with guide grooves, and the bottom of the beam plate is fixedly installed with protrusions, which are slidably installed in the guide grooves.

[0008] As a further improvement to this technical solution, the lifting mechanism includes two hinge rods hinged to the lower surface of the beam plate. The two hinge rods are inclined and parallel to each other, and the other end of the hinge rods is hinged to the upper surface of the brake plate.

[0009] As a further improvement to this technical solution, sleeves are fixedly installed at the four corners of the upper surface of the brake plate, and guide posts are fixedly installed at the corresponding positions of the lower surface of the oxygen generator equipment. The sleeves are slidably sleeved on the corresponding guide posts, and a fixed wedge block is integrally formed on the top of the outer circumference of the sleeve.

[0010] As a further improvement to this technical solution, the four limiting mechanisms correspond one-to-one with the four sleeves. Each limiting mechanism includes two positioning blocks fixedly installed on the lower surface of the oxygen generator. Two guide rods are fixedly installed between the two positioning blocks, and a slide is slidably mounted on the two guide rods.

[0011] As a further improvement to this technical solution, a movable wedge is integrally formed at the lower end of the slide, and a stop block is fixedly installed at the end of the movable wedge away from the corresponding fixed wedge. A lever is fixedly installed on the U-shaped frame at the position corresponding to each limiting mechanism, and the lever is located on the side of the stop block close to the movable wedge.

[0012] As a further improvement to this technical solution, a spring is sleeved on the guide rod, and the two ends of the spring abut against the slide and one of the positioning blocks respectively. The spring is used to push the slide closer to the fixed wedge block.

[0013] As a further improvement to this technical solution, the clamping mechanism includes a positioning seat fixedly installed on the lower surface of the oxygen generator equipment. Two clamping rods are hinged to the side of the positioning seat away from the beam plate. A rubber block is fixedly installed at the other end of the clamping rod. An arc-shaped groove is machined on the side of the two rubber blocks that are close to each other.

[0014] As a further improvement to this technical solution, a movable rod is slidably provided on the positioning seat. One end of the movable rod is fixedly connected to the beam plate through a bracket, and a moving block is fixedly installed on the other end of the movable rod. An inclined rod is hinged to the moving block at the position corresponding to the two clamping rods, and the other end of the inclined rod is hinged to the middle section of the corresponding clamping rod.

[0015] As a further improvement to this technical solution, an extension plate is fixedly installed on the side of the U-shaped frame away from the clamping mechanism. Two positioning holes are opened on the extension plate. A fixing block is fixedly installed on the lower surface of the oxygen generator. A pin is slidably inserted through the fixing block. The upper end of the pin is integrally formed with an end.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This cubic oxygen concentrator with a stable braking chassis, during braking, the U-shaped frame drives the beam plate to move via the guide groove and protrusion. On one hand, the beam plate, through the movable rod, moving block, and inclined rod, causes two clamping rods to drive the rubber block to grip the connecting shaft, restricting the rotation of the connecting shaft and the directional wheel, forming the first layer of wheel axle braking. On the other hand, through the inclined hinge rod, the brake plate is pushed vertically downward along the guide column and sleeve and pressed against the ground, using the friction between the brake plate and the ground to form the second layer of braking. After the brake plate moves to the lower position, the fixed wedge block on the sleeve slides over the moving wedge block. The moving wedge block is reset under the action of the spring and stops above the fixed wedge block. With the help of the lever, slide, and stop block, the brake plate is locked to prevent the brake plate from rebounding. Then, the pin is inserted into the brake positioning hole to maintain the braking state. The above structure sequentially realizes the gripping of the connecting shaft, the brake plate contacting the ground friction, and the brake plate position locking, so that the chassis has multiple stable braking effects, ensuring the stability and reliability of the cubic oxygen concentrator during use.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] Please see Figures 1-10As shown, the purpose of this embodiment is to provide a cubic oxygen concentrator with a stable braking chassis. The device includes an oxygen concentrator 1, two omnidirectional wheels 11 and two directional wheels 12. The two omnidirectional wheels 11 and the two directional wheels 12 are respectively fixedly installed at the four corners of the lower surface of the oxygen concentrator 1, that is, each of the four corners of the oxygen concentrator 1 is provided with a walking wheel. A connecting shaft 13 is coaxially fixed between the two directional wheels 12. When in use, the omnidirectional wheels 11 and the directional wheels 12 contact the ground, thereby facilitating the movement of the cubic oxygen concentrator.

[0021] Below the oxygen concentrator 1, a beam plate 4, a U-shaped frame 5, and a brake plate 2 are arranged sequentially. The beam plate 4 is horizontally slidably mounted on the lower surface of the oxygen concentrator 1 via a slide rail slider structure. The U-shaped frame 5 is horizontally slidably mounted on the oxygen concentrator 1 via several U-shaped guide frames 53, thereby enabling both the beam plate 4 and the U-shaped frame 5 to move horizontally. The U-shaped guide frames 53 are fixed to the bottom of the oxygen concentrator 1 and have guide grooves 52. A protrusion 42 is fixedly installed on the bottom of the beam plate 4 and slides on the guide plate. In the groove 52, the transmission cooperation between the beam plate 4 and the U-shaped frame 5 is realized. Two clamping mechanisms 6 are provided at the end of the beam plate 4 near the connecting shaft 13. The clamping mechanism 6 is used to clamp and fix the connecting shaft 13, thereby playing the first step of braking. The bottom of the beam plate 4 is provided with a lifting mechanism for driving the brake plate 2 to move in the vertical direction, so as to drive the brake plate 2 down to contact the ground. The outer wall of the U-shaped frame 5 is provided with four limiting mechanisms 7 for locking the position of the brake plate 2, so as to prevent the brake plate 2 from rebounding after it moves down to the position.

[0022] During braking, when the U-shaped frame 5 moves horizontally away from the connecting shaft 13, it pushes the protrusion 42 through the side wall of the guide groove 52, causing the U-shaped frame 5 to move synchronously with the beam plate 4. This causes the beam plate 4 to move the clamping mechanism 6 and the lifting mechanism. The clamping mechanism 6 clamps and fixes the connecting shaft 13, thereby restricting the rotation of the connecting shaft 13 and the two directional wheels 12, thus achieving the first step of braking. The lifting mechanism drives the brake plate 2 to move downward. When the brake plate 2 moves to the lower position, it contacts the ground. The second step of braking is achieved through the friction between the brake plate 2 and the ground. At the same time, the limiting mechanism 7 locks the position of the brake plate 2, restricting the upward movement of the brake plate 2, thereby ensuring a stable and reliable braking effect.

[0023] The following details the structure of the lifting mechanism, referring to... Figure 4The lifting mechanism includes two hinge rods 41 hinged to the lower surface of the beam plate 4. The two hinge rods 41 are inclined and parallel to each other. The other end of the hinge rods 41 is hinged to the upper surface of the brake plate 2. Sleeves 21 are fixedly installed at the four corners of the upper surface of the brake plate 2. Guide columns 14 are fixedly installed at the corresponding positions of each sleeve 21 on the lower surface of the oxygen generator equipment 1. The sleeve 21 is slidably sleeved on the corresponding guide column 14. A fixed wedge block 22 is integrally formed on the top of the outer circumference of the sleeve 21. Through the cooperation between the sleeve 21 and the guide column 14, the brake plate 2 is restricted to move only in the vertical direction.

[0024] The four limiting mechanisms 7 correspond one-to-one with the four sleeves 21. The structure of the limiting mechanisms 7 is described in detail below, please refer to... Figure 6 , Figure 9 and Figure 10 The limiting mechanism 7 includes two positioning blocks 71 fixedly installed on the lower surface of the oxygen generator 1. Two guide rods 72 are fixedly installed between the two positioning blocks 71. A slide 73 is slidably mounted on the two guide rods 72. A movable wedge 74 is integrally formed at the lower end of the slide 73. The movable wedge 74 and the corresponding fixed wedge 22 are both machined with inclined surfaces on the side that are close to each other. A stop block 75 is fixedly installed at the end of the movable wedge 74 away from the corresponding fixed wedge 22. A lever 54 is fixedly installed on the U-shaped frame 5 at the position corresponding to each limiting mechanism 7. The lever 54 is located on the side of the stop block 75 close to the movable wedge 74. A spring 76 is mounted on the guide rod 72. The two ends of the spring 76 abut against the slide 73 and one of the positioning blocks 71 respectively. The spring 76 is used to push the slide 73 closer to the fixed wedge 22.

[0025] The following details the structure of the clamping mechanism 6, referring to... Figure 5 The clamping mechanism 6 includes a positioning seat 61 fixedly installed on the lower surface of the oxygen generator 1. Two clamping rods 62 are hinged to the side of the positioning seat 61 away from the beam plate 4. Rubber blocks 63 are fixedly installed at the other end of the clamping rods 62. Arc-shaped grooves are machined on the side of the two rubber blocks 63 that are close to each other. The arc-shaped grooves are used to fit with the outer peripheral surface of the connecting shaft 13 to increase the contact area and friction during clamping. A movable rod 64 is slidably installed through the positioning seat 61. One end of the movable rod 64 is fixedly connected to the beam plate 4 through a bracket. A moving block 65 is fixedly installed at the other end of the movable rod 64. An inclined rod 66 is hinged to the moving block 65 at the position corresponding to the two clamping rods 62. The other end of the inclined rod 66 is hinged to the middle section of the corresponding clamping rod 62.

[0026] In addition, an extension plate 51 is fixedly installed on the side of the U-shaped frame 5 away from the clamping mechanism 6. The other end of the extension plate 51 extends to the outside of the oxygen generator equipment 1 and is fixedly installed with a handle so that the operator can push and pull the U-shaped frame 5 from the outside of the chassis. Two positioning holes 511 are opened on the extension plate 51. The positioning hole 511 closer to the U-shaped frame 5 corresponds to the moving state, and the positioning hole 511 farther away from the U-shaped frame 5 corresponds to the braking state. A fixing block 3 is fixedly installed on the lower surface of the oxygen generator equipment 1. A pin 31 is slidably inserted through the fixing block 3. The upper end of the pin 31 is integrally formed with an end head 32. When the pin 31 is inserted into different positioning holes 511, the U-shaped frame 5 and the extension plate 51 can be locked in the corresponding moving position or braking position to prevent the U-shaped frame 5 from malfunctioning under vibration or external force.

[0027] When the chassis is in a moving state, the pin 31 is inserted into the positioning hole 511 corresponding to the moving state, and the end 32 abuts against the upper surface of the fixing block 3, thereby locking the position of the extension plate 51, the handle, and the U-shaped frame 5. At this time, the brake plate 2 is at its highest point, and there is a certain gap between it and the ground, which will not obstruct movement. The clamping mechanism 6 does not clamp the connecting shaft 13, and the connecting shaft 13 and the two directional wheels 12 can rotate freely. Therefore, the chassis and the cubic oxygen generator can move freely. After moving the cubic oxygen generator to the predetermined position, the operator pulls the pin 31 out of the current positioning hole 511 and then pulls the handle. The handle drives the U-shaped frame 5 to move synchronously through the extension plate 51. As the U-shaped frame 5 moves away from the connecting shaft 13, the sidewall of the guide groove 52 abuts against the protrusion 42, thereby pushing the protrusion 42 and the beam plate 4 to move synchronously. During this process, the beam plate 4 converts the horizontal movement into vertical movement through the inclined hinge rod 41, causing the brake plate 2 to move downward in the vertical direction. On the other hand, it drives the movable rod 64 to move synchronously. The movable rod 64 drives the moving block 65 to move. The moving block 65 drives the two clamping rods 62 to rotate and approach each other through the two inclined rods 66. The clamping rods 62 drive the rubber blocks 63 to move synchronously, so that the arc grooves on the two rubber blocks 63 are tightly abutted against the connecting shaft 13, thereby achieving the clamping and braking of the connecting shaft 13.

[0028] During the downward movement of brake plate 2, brake plate 2 drives all sleeves 21 to move synchronously downward along guide post 14. When the fixed wedge block 22 on sleeve 21 contacts the corresponding moving wedge block 74, the inclined surface of the fixed wedge block 22 slides relative to the inclined surface of the moving wedge block 74, thereby converting part of the vertical downward movement into horizontal thrust, pushing the moving wedge block 74 and slide 73 towards the compression spring 76, making way for the downward movement of brake plate 2. When brake plate 2 touches the ground, the fixed wedge block 22 moves below the moving wedge block 74. At this time, the moving wedge block 74 is no longer pushed laterally by the fixed wedge block 22. The spring 76 returns to its original position under the action of its rebound force, causing the moving wedge 74 to move above the corresponding fixed wedge 22. Thus, the moving wedge 74 blocks the fixed wedge 22 from moving upward, thereby locking the position of the brake plate 2 and preventing the brake plate 2 from rebounding due to external force or vibration in the braking state. This keeps the brake plate 2 in contact with the ground and enhances the braking capability of the chassis. At this time, the positioning hole 511 corresponding to the braking state moves directly below the pin 31. The operator inserts the pin 31 into the positioning hole 511 to switch the chassis to the braking state and maintain it, ensuring the stable use of the cubic oxygen generator.

[0029] When it is necessary to release the brake to move the cubic oxygen generator again, the operator pulls the pin 31 out of the current positioning hole 511, and then holds the handle to move the extension plate 51 and the U-shaped frame 5 toward the connecting shaft 13. During this process, the U-shaped frame 5 drives all the levers 54 to move synchronously. The levers 54 first push the stop block 75, causing the stop block 75 to drive the slide 73 and the moving wedge block 74 to move synchronously. The spring 76 is compressed and elastically contracts, and the moving wedge block 74 exits the locked position above the fixed wedge block 22. The U-shaped frame 5 continues to move, and drives the guide groove 52 on it to move synchronously. When the moving wedge block 74 After the wedge block 22 is completely disengaged, the side wall of the guide groove 52 pushes the protrusion 42, causing the beam plate 4 to move. This sequence of actions ensures that the locking mechanism 7 on the brake plate 2 is released first, and then the lifting mechanism and the clamping mechanism 6 are reset by the reverse movement of the beam plate 4. The inclined hinge rod 41 moves the brake plate 2 up off the ground, and at the same time the movable rod 64 moves the moving block 65. The moving block 65 drives the two clamping rods 62 to open through the inclined rod 66, and the rubber block 63 releases the connecting shaft 13, thereby restoring the free rotation of the connecting shaft 13 and the directional wheel 12, and returning the chassis to a movable state.
