Description

Technical Field

[0001] The present invention relates to the field of special vehicles, and in particular to a connection device for a communication vehicle. Background Art

[0002] With the advancement of modern science and technology, special vehicles such as communication vehicles have been widely used in various fields. Communication vehicles are widely used in cities and outdoor environments; they not only have functions such as mobile bearing, but are also widely used in various fields such as detection, transportation, and rescue, using their own communication functions and various auxiliary function equipment to perform various tasks. Faced with complex environments, there is also considerable room for improvement in the research of special vehicles.

[0003] In actual engineering practice, there are the following problems:

[0004] 1. The communication vehicles in the prior art are generally equipped with communication cabinets for carrying various communication equipment such as radio stations, etc. At the same time, facing the complex environment such as the plateau environment, they are equipped with oxygen generators, etc. However, the equipment is different from civilian equipment that can be placed arbitrarily. The space in the vehicle is limited, and generally needs to be placed in a centralized manner, such as in an electrical cabinet; and the power supply connectors in the vehicle are often placed in a centralized manner, so most of the electrical equipment is placed in a centralized manner. The cabinet generally has a cabinet door. During the centralized placement process, there is a grid space in the cabinet door for placing the oxygen generator or similar components. The oxygen generator outputs oxygen through a connecting pipe, and a hole is opened on the cabinet door for the connecting pipe to extend.

[0005] In actual use, since the communication cabinet of the communication vehicle is not specially manufactured to accommodate the oxygen concentrator, and the oxygen concentrator is not a standard mandatory component but a subsequent purchase, the above-mentioned openings are often opened slightly larger to accommodate more types of functional equipment. Therefore, the diameter of the opening is not compatible with the diameter of the oxygen concentrator connecting pipe, and the opening size cannot be suitable for oxygen concentrators of various specifications or multiple types of functional equipment.

[0006] 2. As mentioned above, even if the above-mentioned connecting pipe is adapted to the hole on the cabinet door through intermediate adapting connectors such as nozzles and joints provided on the cabinet door, the structure and size of the nozzles will often lead to unexpected spatial interference between the connecting pipe, joints and nozzles during the cabinet door opening process.

[0007] 3. The cabinet doors that are commonly known to the public often include handles or grip grooves to adapt to the hand shape, making it easy to grasp and open and close; however, additional processing of the structure is required.

[0008] Fourth, the connecting pipe as mentioned above is not directly connected to the end nozzle, but is connected in the middle through a joint, and the joint is often rigid and heavy, requiring an additional supporting structure. The fulcrum of this supporting structure is set on the cabinet door, which has the defect of affecting the flexibility and space of the cabinet door.

[0009] V. The joint as described above not only needs to be supported, but also needs to be fixed through a fixing structure to prevent swinging in the front-back, left-right directions. The existing technologies for dealing with this include clamps, but the forms of the clamps are single and cannot clamp different structural environments more flexibly. Summary of the Invention

[0010] To overcome the above problems, the present invention proposes a solution to simultaneously solve the above-mentioned multiple problems.

[0011] The technical solution adopted by the present invention to solve its technical problems is: A connection device for a communication vehicle, used to connect with the air outlet of an oxygen generator, where the oxygen generator is placed in an electrical cabinet. The connection device includes a connecting pipe, a joint, a clamping and supporting module, and a nozzle; the electrical cabinet includes a cabinet door, and a cabinet hole is opened on the cabinet door. The cabinet hole is opened at the opening end of the cabinet door and is located in the upper right corner of the cabinet door. The nozzle includes a spray pipe, a sleeve, a stepped portion, and a handle rod. The clamping and supporting module includes a support plate and a clamping member. The clamping member includes an arc portion, a lower connecting plate, a horizontal plate, and an upper connecting plate; the lower end of the arc portion is connected to the lower connecting plate, the upper end of the arc portion is connected to the horizontal plate, the right end of the horizontal plate is connected to the upper connecting plate, and the upper connecting plate extends vertically;

[0012] One end of the connecting pipe is connected to the air outlet, and the other end is connected to one end of the joint. The other end of the joint abuts against the nozzle; the joint is fixed by the clamping and supporting module. The support plate is connected to the inner side of the right wall of the electrical cabinet. The length of the support plate extending out of the right wall is less than the diameter of the joint. When the joint is fixed, the support plate supports below the joint, the arc portion abuts against the joint, the lower connecting plate is connected to the support plate through a connecting member, and the upper connecting plate is also connected to the right wall through a connecting member;

[0013] The diameter of the spray pipe is larger than that of the sleeve. The spray pipe and the sleeve are connected through the stepped portion, and the handle rod is connected to the stepped portion. The handle rod is located inside the spray pipe; the other end of the joint abuts against the stepped portion, the sleeve is located inside the joint, and there is a gap between the sleeve and the joint. The diameter of the sleeve is smaller than that of the joint; the spray pipe is threadedly connected to the cabinet hole to conveniently adjust the positional relationship between the nozzle and the cabinet door; when the cabinet door rotates and opens, there is no interference between the sleeve and the joint.

[0014] Preferably, the length of the sleeve is less than the length of the spray pipe.

[0015] Preferably, the length of the sleeve is less than the thickness of the cabinet door.

[0016] Preferably, the cabinet door rotates and opens.

[0017] Preferably, after the joint is fixed, there is a gap between the cross plate and the joint.

[0018] Preferably, the axis of the handle rod coincides with the center line of the sleeve.

[0019] Preferably, a sealing ring band is provided on the step portion.

[0020] Preferably, the joint abuts against the sealing ring band.

[0021] Preferably, the connection between the handle rod and the step portion is a detachable connection.

[0022] Preferably, after the handle rod is removed, a filter net is detachably installed in the spray pipe.

[0023] The beneficial effects of the present invention are as follows:

[0024] First, in response to the first point raised in the background art, the nozzle with a double-sleeve structure is connected to the joint. The large and small sleeves in the double-sleeve structure are connected to each other. A step portion is provided between the large and small sleeves. The small sleeve extends into the connector, and the joint abuts against the step portion. The size of the large sleeve is adapted to the cabinet door hole and is connected to the cabinet door hole, so as to adapt the sizes of the output pipe and the joint to the size of the cabinet door hole.

[0025] Second, in response to the second point raised in the background art, the cabinet door hole is provided at the rotation opening end of the cabinet door, and there is a radial gap between the small sleeve and the joint after being sleeved; due to being provided at the opening end and the short length of the small sleeve, even if the cabinet door is opened a small distance, the rotation angle of the cabinet door is small, and correspondingly, the rotation angles of the cabinet door hole and the nozzle are also small. Therefore, the short small sleeve in the nozzle deflects less and does not interfere with the joint.

[0026] Third, in response to the third point raised in the background art, there is no need to additionally process the holding groove on the cabinet door. The handle rod can be directly connected to the inner side of the step portion between the large and small sleeves, reducing the processing difficulty and processing steps of the handle structure.

[0027] Fourth, in response to the fourth point raised in the background art, although the cabinet door is a component directly related to the joint and the support structure, the design concept is changed, and the support structure is provided on the cabinet wall. For the cabinet wall with the property of a fixing member, it is reasonable to add an additional structure. Therefore, there is no need to set an additional structure on the cabinet door to reduce the redundant structure of the cabinet door and make the flexibility and space of the cabinet door during movement better.

[0028] Fifth, in response to the fifth point raised in the background art, a fixture with a single chuck is provided to adapt to the right-angle installation environment formed by the support structure and the cabinet wall, and at the same time, the length of the support structure is appropriately shortened to facilitate docking with the single chuck or adjusting the clamping size.

[0029] Note: The above designs are not in any particular order, and each one makes the present invention distinct and significantly advanced compared to the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
