Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a front wheel guard for docking a medical tank truck. Background Art
[0002] Clinical surgery will generate a large amount of waste liquid, which is usually carried in plastic soft bags, waste liquid collection bottles or metal buckets. It contains flushing fluid, blood, liquid medicine and tissue substances, which need to be discharged in time. Due to the large amount, movement will cause splashing and may cause infection to personnel. Therefore, there is an automated waste liquid collection device (drainage station) on the market, which automatically collects, automatically docks and cleans, and does not require manual dumping. The working principle is that the drainage station is equipped with a carrier and a set of connectors, which are connected to the water connector of the tanker when docked. The drainage station is fixed in a certain position, and the tanker containing liquid is parked and docked with the drainage station. After power is turned on, it is attracted by a magnet, and the water connector of the drainage station is connected to the water connector of the tanker, as shown in the attached figure. Figure 6 As shown in the prior art, the waste liquid is discharged into the sewer through the pipeline through the water pipe of the drainage station, and then washed with clean water. After the washing is completed, the tank truck and the drainage station are separated manually or by power off.
[0003] The whole operation requires manual pushing of the tank truck to the drainage station, and forcing the left and right door bumpers of the drainage station to open, completing the docking, emptying and cleaning process. After the procedure is completed, the tank truck is withdrawn by the force of the door bumper spring. However, the following problems are prone to occur when the tank truck is docked with the drainage station. Sometimes the electromagnet has residual magnetism, the tank truck is attracted, and the spring force of the door bumper is not enough to bounce the tank truck open. The door bumper is prone to rust and looseness, and the elastic force is reduced, making the door bumper insufficient to bounce the tank truck open, causing repeated docking. Secondly, the door bumper structures on both sides of the drainage station are relatively complex, with many faults and frequent maintenance. Utility Model Content

DETAILED DESCRIPTION
[0023] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.
[0024] Please see attached Figure 1 -Attached Figure 4 As shown, a front wheel shield for docking a medical tanker includes a shield 1 and a shield ear 2 arranged at the front end of the shield 1 and corresponding to the front wheel 61 of the tanker 6, Figure 1 and attached Figure 2 Only the part of the front wheel guard corresponding to the two front wheels 61 of the tanker 6 is drawn. The two front wheels 61 of the tanker 6 refer to the two wheels adjacent to each other on both sides of the water joint of the tanker 6. The number of the cover ears 2 is two and they are respectively covered on the two front wheels 61. The cover ears 2 are made of elastic plastic material, so that when the tanker 6 is docked with the drainage station 7, the cover ears 2 are squeezed to deform the cover ears 2. After the tanker 6 discharges and cleans the program, the electromagnet 71 is powered off, and the tanker 6 is automatically separated by the elastic release of the cover ears 2. There is no need to open the door collision block 72, and there is no need for the docking device structure that floats up and down, so as to reduce the situation of repeated docking between the tanker 6 and the drainage station 7.
[0025] The ear 2 includes an outer baffle plate 21 and a buffer structure arranged in the outer baffle plate 21, wherein the buffer structure includes an arc plate 22 connected to the front end of the outer baffle plate 21 and a buffer cavity 23 formed by sealingly connecting the arc plate 22 and the outer baffle plate 21, wherein a plurality of buffer rings 24 are arranged in the buffer cavity 23, and each buffer ring 24 is provided with a cross rib 28, and the cross rib 28 is used to improve the fastness of the buffer ring and the service life of the ear, and prevent the buffer ring 24 from losing its resilience after long-term extrusion; preferably, at least 4 buffer rings 24 are arranged in the buffer cavity 23, so that one of the buffer rings 24 is directly opposite to the extrusion position, ensuring that the deformation of the ear is basically concentrated in the local area at the front end of the ear, wherein the elastic plastic material used by the ear 2 is TPV material, that is, the outer baffle plate 21, the arc plate 22, the buffer ring 24, and the cross rib 28 are all made of TPV material, so that when the tank truck 6 is docked with the drainage station 7, the buffer ring 24 is squeezed to produce lateral deformation, and energy is accumulated to form the resilience of TPV.
[0026] In the above embodiment, preferably, an embedding groove 4 is further provided in the outer baffle plate 21, and the embedding groove 4 is used to place an infrared communication PCB board 3 that can sense the docking position of the tank truck. The embedding groove 4 can be arranged facing the front of the front wheel guard, so that the infrared sensor on the infrared communication PCB board 3 faces the front of the tank truck 6, and then senses the docking position of the tank truck 6 and the drainage station 7, and the side of the outer baffle plate 21 is provided with a communication port 5 corresponding to the infrared sensor on the infrared communication PCB board 3, and the communication port 5 is in the shape of a trumpet, which is used to expand the radiation range of the infrared sensor so that the signal can be fan-shaped. Figure 5 As shown, the radiation range of the infrared sensor is 60°, which enables the tank truck 6 to successfully dock with the drainage station 7 to the greatest extent.
[0027] Specifically, as attached Figure 5 and attached Figure 6 As shown, in the initial state, the mobile tanker 6 makes the front wheel guard lightly touch the box of the drainage station 7, at this time, the force f0 between the two is 0; then, after the infrared signal scans the drainage station 7, it gives the main control board an instruction, the main control board energizes the electromagnet 71, and the two electromagnets 71 respectively generate attraction, thereby sucking the tanker 6 to park, so that the tanker 6 and the drainage station 7 are firmly locked, and the two sets of water joints on the tanker 6 and the drainage station 7 are connected. At this time, the front wheel guard or cover ear 2 on the front wheel 61 of the tanker 6 is in a squeezed state, and the cover ear 2 made of TPV and the buffer ring 24 in the cover ear 2 are squeezed under the action of the electromagnet attraction to produce lateral deformation, and accumulate energy to form the resilience of TPV. The resilience at this time is greater than the attraction of the residual magnetism after power failure;
[0028] When the discharge and cleaning procedure of the tank truck 6 is completed, the electromagnet 71 is powered off, and the deformation energy of the cover ear 2 after being squeezed is released in the form of rebound force, thereby completely separating the tank truck 6 from the drainage station 7. The entire process no longer requires the door opening block 72, nor does it require an up and down floating docking device structure to automatically separate the tank truck 6 and the drainage station 7. The structure is simple and the function is stable, and there is no need to repair the docking device structure and the door opening block 72.
[0029] In the above embodiment, preferably, a partition plate 25 is provided between two adjacent buffer rings 24 to improve the firmness of the buffer cavity 23 .
[0030] In the above embodiment, preferably, a fixing ring 26 is further provided in the middle of the four buffer rings 24, and a serrated pattern is provided inside the fixing ring 26. The cover ear 2 is mounted on the top of the rotating shaft of the front wheel 61 of the tank truck 6 through the fixing ring 26, and the fixing rings 26 on the two cover ears 2 are respectively mounted on the rotating shafts of the two front wheels 61, and then fixed to the bottom of the tank truck 6 for docking and collision, and the friction between the front wheel guard and the front wheel 61 is increased by the serrated pattern.
[0031] In the above embodiment, preferably, a reinforcing plate 27 for supporting the arc plate 22 and the embedding groove 4 is further provided in the outer baffle plate 21 to improve the stability of the cover ears and at the same time ensure that the deformation of the cover is basically in the local area of the front end of the front wheel cover.
[0032] In the above embodiment, preferably, the side surface of the outer baffle plate 21 adopts an arc structure, the height of one end of the outer baffle plate 21 connected to the sheath 1 is higher than the height of the docking end of the outer baffle plate 21, and the top surface of the outer baffle plate 21 also adopts an arc structure, and the front wheel guard is formed as a whole by injection molding, and its surface adopts an arc structure in order to generate rebound force for docking collision, and secondly, to facilitate demolding, and also to facilitate the infrared communication PCB board 3 embedded therein to transmit signals.
