Description

Technical Field

[0001] The present application relates to the field of clamp equipment, and in particular to a clamping device suitable for a portable oxygen tank. Background Art

[0002] Portable oxygen tanks are widely used in medical emergency, outdoor activities and special environments (such as plateau hypoxia) to supply oxygen. Their lightness and portability make them an essential tool in rescue and emergency situations. Portable oxygen tanks are usually made of steel or aluminum, filled with compressed oxygen, and provide a stable oxygen supply through a regulating valve and mask.

[0003] In the prior art, portable oxygen tanks need to be moved from one production line to the next production line for assembly or testing during the production process. This requires the portable oxygen tank to be grasped and clamped by a clamping device so that the portable oxygen tank can move stably and reliably; however, the existing clamping device usually includes two jaws, which clamp together on both sides of the oxygen tank to fix the oxygen tank. Each jaw is usually driven by a motor or cylinder. When an error occurs, such as a motor failure or a control system error, resulting in different clamping forces between the two jaws, or an error occurs during the assembly process, resulting in an unbalanced torque, the oxygen tank cannot be reliably grasped or may slip. In particular, when the entire device clamps the oxygen tank and needs to move, if the mechanical equipment suddenly shakes, stagnates, etc., it is more likely to cause the oxygen tank to fall off, causing safety hazards and low production efficiency. Utility Model Content

[0004] To this end, the present application provides a clamping device suitable for a portable oxygen tank to solve the problem of unreliable clamping of the portable oxygen tank during the production process in the prior art.

[0024] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0026] refer to Figure 1-7 The present application discloses a clamping device suitable for a portable oxygen tank, comprising a frame, a bracket 1 connected to the frame, a screw rod 3 rotatably connected to the bracket 1, a motor 6 connected to the bracket 1 and used to drive the screw rod 3 to rotate, and two clamping members 2 respectively threadedly connected to the two ends of the screw rod 3, the outer peripheral walls of the two ends of the screw rod 3 are symmetrically formed with two threaded sections 31 with opposite rotation directions along the length extension direction of the screw rod 3, the two clamping members 2 and the two threaded sections 31 correspond one to one, the clamping member 2 comprises a clamping arm 21 with one end threadedly matched with the threaded section 31, a clamping plate 22 connected to the end of the clamping arm 21 away from the threaded section 31, an arc-shaped clamping surface 221 is formed on the side of the clamping plate 22 away from the clamping arm 21, the arc-shaped clamping surfaces 221 of the two clamping plates 22 are used to respectively abut against two opposite side surfaces of the portable oxygen tank so that the two clamping plates 22 clamp the portable oxygen tank, and the two clamping plates 22 are symmetrically arranged along the center point of the length extension direction of the screw rod 3.

[0027] The motor 6 drives the screw 3 to rotate. The two ends of the screw 3 are respectively two threaded segments 31 with opposite rotation directions. The two clamping arms 21 are respectively threadedly connected to the two threaded segments 31, and the two clamping members 2 (clamping arms 21) are connected to the same screw 3. The two clamping plates 22 are symmetrically arranged along the center point of the length extension direction of the screw 3. This design ensures that when the motor 6 drives the screw 3 to rotate, the two clamping members 2 can be synchronously and evenly close to or away from the center point, thereby avoiding the problem of uneven clamping force. Through this structural design, the motor 6 drives the two clamping plates 22 to approach or move away from each other through the screw 3, thereby achieving reliable clamping of the portable oxygen tank. The two arc-shaped clamping surfaces 221 can fit tightly to the outer surface of the portable oxygen tank, provide stable support and clamping force, and effectively avoid the risk of the oxygen tank slipping during transportation, thereby improving the reliability and safety of the device.

[0028] In addition, the applicant needs to add that this application only involves technical improvements to the clamping device, while the structures involved in the handling and transfer include transportation lines (conveyor belts, etc.), positioning devices, and handling manipulators, etc.; in the actual production process, portable oxygen tanks are usually handled and assembled through automated assembly lines. The conveyor belt is the main part of the transportation line, usually composed of rollers, chains, belts, etc., which can smoothly and continuously transport the oxygen tank to the designated position. During the transmission process, the positioning device includes a positioning baffle, a sensor, etc., which is used to accurately control the docking position of the oxygen tank; the clamping device involved in this application is usually used in conjunction with a handling manipulator. After receiving the oxygen tank on the conveyor belt, the manipulator stably grasps the oxygen tank through the clamping device and transports it to the designated processing position or the next conveyor belt. The movement path and grasping action of the manipulator are usually precisely controlled by a pre-programmed control system to ensure the stability and reliability of the handling process; the transportation line, positioning device, and handling manipulator are all prior art, and this application will not repeat them.

[0029] The bracket 1 includes a support 11 connected to the frame, two support plates 12 respectively connected to the two ends of the support 11, the two ends of the screw rod 3 are respectively rotatably connected to the support plates 12, the clamping arm 21 includes a moving slider 211 threadedly connected to the threaded section 31, and an arm rod 212 connected to the moving slider 211, the clamping plate 22 is connected to one end of the arm rod 212 away from the moving slider 211, the length extension direction of the screw rod 3 is parallel to the top surface of the support 11, and the bottom surface of the moving slider 211 is against the top surface of the support 11.

[0030] The motor 6 drives the movable slider 211 to move along the length extension direction of the screw rod 3 through the screw rod 3. Since the bottom surface of the movable slider 211 abuts against the top surface of the support 11, this design effectively limits the rotation of the movable slider 211, so that the movable slider 211 can only move along the length extension direction of the screw rod 3.

[0031] The screw rod 3 includes a first section 32 with one end rotatably connected to the support plate 12 and a second section 33 with one end rotatably connected to the other support plate 12. The end of the first section 32 away from the support plate 12 is connected to the end of the second section 33 away from the support plate 12 via a coupling 34.

[0032] The first section 32 and the second section 33 are connected by a coupling 34, so that the screw rod 3 can be split into two sections. This design facilitates installation and maintenance, because when the screw rod 3 needs to be replaced or repaired, only one section can be disassembled without disassembling the entire screw rod 3. The use of the coupling 34 ensures the coaxiality and synchronization of the two sections of the screw rod 3, and ensures the stability and consistency of the overall structure.

[0033] In some embodiments, the screw rod 3 may be an integral structure.

[0034] One end of the arm 212 away from the movable slider 211 is connected to the support plate 213, and a plurality of first hole grooves 222 are provided on the side of the clamping plate 22 away from the arc-shaped clamping surface 221. A plurality of second hole grooves 2131 matching the first hole grooves 222 are provided on the side of the support plate 213 away from the arm 212. The plurality of first hole grooves 222 correspond one to one with the plurality of second hole grooves 2131. A positioning rod 5 is connected to the bottom of the first hole groove 222, and the other end of the positioning rod 5 extends to the second hole groove 2131. A clearance hole 2132 is provided at the bottom of the second hole groove 2131 for facilitating the insertion of the positioning rod 5. The positioning rod 5 is sleeved with a cylindrical spring 4, and one end of the cylindrical spring 4 abuts against the bottom of the first hole groove 222, and the other end abuts against the bottom of the second hole groove 2131.

[0035] The design of the cylindrical spring 4 can provide buffering and shock absorption for the clamping plate 22, avoiding rigid contact between the clamping plate 22 and the support plate 213, thereby reducing the impact of mechanical stress and friction on the structure. This buffering effect not only improves the durability and reliability of the clamping device, but also provides a more stable clamping force when clamping a portable oxygen tank, preventing the oxygen tank from being clamped too much or too little; the positioning rod 5 plays a role in limiting the cylindrical spring 4 in the entire structure. The positioning rod 5 runs through the first hole groove 222 and the second hole groove 2131. The positioning rod 5 is designed to avoid position interference through the design of the clearance hole 2132.

[0036] In some embodiments, the plurality of first slots 222 is 4, and the 4 first slots 222 are distributed at the four corners of the clamping plate 22. In this way, the cylindrical spring 4 can be more stably distributed on the entire clamping plate 22, providing uniform buffering and supporting effects therefor.

[0037] The bottom of the first hole groove 222 is provided with a threaded hole threadedly connected to one end of the positioning rod 5. The design of the threaded hole allows the positioning rod 5 to be easily disassembled and replaced. When maintenance or replacement is required, the positioning rod 5 can be removed from the threaded hole by simply rotating it.

[0038] The motor 6 is a reduction motor.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
