Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a three-dimensional frame connected by slide rail supports. Background Art

[0002] With the continuous development of medical equipment, the supporting equipment of medical beds is also constantly upgraded. The upgraded tube needs to be placed in the lead room, centered, and the size of the lead room is, for example, 820x 610x 1500mm. Since the tube is fragile and needs to be replaced frequently, the internal space of the lead room is small and the height does not support manual entry, so it is impossible to manually enter and replace it.

[0003] Moreover, after the replacement, the distance from the focus of the tube to the upper surface of the Ion Chamber is required to be 1000mm. The Ion Chamber refers to the main body of the ionization chamber. Since there is a longitudinal spacing requirement between the focus of the tube and the Ion Chamber, and the shape of the tube is irregular and cannot be directly measured, there are control difficulties. The equipment is required to have a lifting and adjusting function, as well as a pulling function to pull the tube out of the lead room.

[0004] If a new lifting mechanism is added to meet the above requirements, the cost is too high and the cost performance is too low. In addition, the rack must be fixed in the lead room, and the method of pulling out the universal wheel to replace the tube cannot be adopted. Utility Model Content

DETAILED DESCRIPTION

[0026] Please refer to Figure 1 The present embodiment provides a three-dimensional frame 120 connected by slide rail support, including a frame 100, a pulley assembly 200 and a limit assembly 300.

[0027] Please refer to Figure 1 and Figure 5 The frame 100 is provided with a base 110 at the bottom, and the base is fixed at a preset position of the lead room. Regarding the preset position, in some embodiments, a threaded hole is reserved on the floor of the lead room, and the base 110 is connected to the reserved threaded hole of the lead room by screws. After the assembly and debugging of the frame 120 is completed, the whole frame 120 is placed in the lead room.

[0028] Please refer to Figure 1 and Figure 2 The pulley assembly 200 includes a pulley 210 and a slide rail 220. The two slide rails 220 are both mounted on the rack 100. The two slide rails 220 are parallel to each other and are mounted on both sides of the rack. Figure 2 As shown in the figure, two slide rails 220 are installed on both sides of the rack 100, one on the left and one on the right. The trolley 210 is connected to the slide rails 220, and the trolley 210 and the rack 100 can move relative to each other through the slide rails 220.

[0029] like Figure 1 As shown, the ball tube 20 is installed on the pulley 210, and the ball tube 20 is detachably installed on the pulley 210 to realize the replacement of the ball tube 20. The pulley 210 is provided with a ball tube 20 installation position, and the ball tube 20 is detachably installed at the ball tube 20 installation position of the pulley 210. When the ball tube 20 is installed on the pulley 210, the ball tube 20 is moved horizontally on the rack 100 through the passage of the slide rail 220. The ball tube 20 can be pulled out of the lead room, and returned to the lead room after the ball tube 20 is replaced.

[0030] It should be noted that when the ball tube 20 is installed on the pulley 210, specifically in the installation position of the ball tube 20, when the structural dimensions are known, the relative position of the focus of the ball tube and the pulley 210 is in a known state, so that the relative dimensions of the focus of the ball tube and the pulley 210 are known, and the vertical spacing dimension between the focus of the ball tube and the pulley 210 can be known in advance as a preset value.

[0031] Please refer to Figure 1 and Figure 6 The limit assembly 300 includes a mounting plate 310, an adjustment gasket and a limit block 330. The limit assembly 300 is installed on the rack 100, and the limit assembly 300 is located below the pulley 210. The mounting plate 310 is overlapped on the rack 100 to form a corresponding overlap position. The mounting plate 310 and the rack 100 are connected by screws, and the screws are specifically located in the overlap area. Please refer to Figure 1 , showing the adjusting gasket installation position 311, where the adjusting gasket is located. In order to cooperate with the screw at this position, the adjusting gasket is specially provided with a through hole, and the through hole is used for screw insertion. By installing the adjusting gasket between the overlapping part of the mounting plate 310 and the frame 100, when the number of the adjusting gaskets is two or more, they are installed in a stacked manner, so as to adjust the vertical spacing size between the mounting plate 310 and the pulley 210 by controlling the number of the adjusting gaskets.

[0032] The vertical distance between the mounting plate 310 and the focus of the tube can be adjusted by combining the vertical spacing of the tube focus and the pulley 210. Figure 6 A plurality of limit blocks 330 are installed on the upper side of the mounting plate 310. The limit blocks 330 are used to assist the installation of the ionization chamber body. The position of the ionization chamber body on the mounting plate 310 is limited by the limit blocks 330. When the ionization chamber body is placed on the limit assembly 300, the distance between the main body of the pulley 210 and the limit assembly 300 can be measured, and the distance from the upper surface of the ionization chamber body to the focus of the tube can be adjusted by controlling the number of adjusting gaskets, so that the distance is controlled to a predetermined value.

[0033] In summary, the three-dimensionally divided frame 120 of this embodiment perfectly realizes the installation of the ball tube 20 outside the lead room, and realizes the pulling out and replacement of the ball tube 20. The ball tube 20 is replaced outside the lead room, so that the adjustment method of the ball tube 20 during assembly is convenient and easy for workers to operate. In addition, the three-dimensionally divided frame 120 realizes the installation and debugging of the ionization chamber body.

[0034] In order to smoothly realize the setting of the vertical spacing dimension between the focus of the tube and the pulley 210 as a preset value when the tube 20 is located at the tube 20 installation position, the relevant structure is machined to control the accuracy of the structure and ensure the distance dimension from the focus of the tube to the main surface of the pulley 210.

[0035] Machining specifically concerns the pulley assembly 200 .

[0036] The slide rails 220 are fixed by screw installation. The screw installation spaces involved in the slide rails 220 are controlled by machining. The slide rails 220 are debugged and installed to ensure that the two slide rails 220 are parallel to each other and run smoothly.

[0037] In some embodiments, see Figure 2 The slide rail 220 includes a fixed portion 221 and a movable portion 222, and the movable portion 222 and the fixed portion 221 can slide relative to each other. It should be noted that: Figure 2 and Figure 1 Only the general structure of the slide rail 220 is shown. The fixed portion 221 is fixedly connected to the frame 100, and the pulley 210 is fixedly connected to the moving portion 222, so that the relative movement of the pulley 210 and the frame 100 can be smoothly realized, and the setting of the pulley 210 entering and exiting the lead room can be realized under the condition that the frame 100 is fixed in the lead room.

[0038] Please refer to Figures 1 to 4 The trolley 210 includes a trolley main board 211, a left support member 212, a right support member 213 and a rear support member 214. The trolley main board 211 is fixedly connected to the moving parts 222 of the two slide rails 220. Under the condition that the moving parts 222 and the fixed parts 221 can slide relative to each other, the relative movement of the trolley main board 211 and the rack 100 is realized. The left support member 212, the right support member 213 and the rear support member 214 are all fixedly installed on the trolley main board 211. The left support member 212, the right support member 213 and the rear support member 214 form a mounting position for the ball tube 20, and the ball tube 20 is installed on the left support member 212, the right support member 213 and the rear support member 214.

[0039] For details, please refer to Figure 1 and Figure 2 The left support member 212 is provided with an arc-shaped opening groove 212a, and the right support member 213 is also provided with an arc-shaped opening groove 212a. The opening of the arc-shaped opening groove 212a faces upward. When the ball tube 20 is installed, the two axial ends of the ball tube 20 are respectively supported on the left support member 212 and the right support member 213, specifically at the position of the arc-shaped opening groove 212a. The arc shape of the arc-shaped opening groove 212a is in contact with the arc shape of the axial end of the ball tube 20.

[0040] Also, please refer to Figure 1 and Figure 4 The rear support member 214 is provided with a vertical portion 214a, and a screw space is opened in the vertical portion 214a. The vertical portion 214a is fixedly connected to the ball tube 20 by screws, so that the ball tube 20 is smoothly fixed on the pulley 210. When the ball tube 20 needs to be removed, it is only necessary to release the limit between the ball tube 20 and the rear support member 214.

[0041] Please refer to Figure 1 and Figure 4 The rear support member 214 includes a transverse portion, and the vertical portion 214a of the rear support member 214 is connected to the transverse portion. The transverse portion is connected to the pulley main board 211 through screws to achieve fixed installation of the rear support member 214.

[0042] The left support member 212 and the right support member 213 are both mounted on the pulley main plate 211 by screws, and the rear support member 214 is mounted on the pulley main plate 211. Figure 1 , Figure 3 and Figure 4 In some embodiments, the left support member 212 and the right support member 213 are each provided with a plurality of first oblong holes 212b, which are used for screw insertion and installation. The vertical portion 214a is provided with second oblong holes 214b, which are used for screw insertion and installation, specifically for connecting screws between the rear support member 214 and the ball tube 20.

[0043] Please refer to Figure 1 , Figure 3 and Figure 4 , it is limited that the length direction of the first oblong hole 212b and the length direction of the second oblong hole 214b are both set horizontally, and the length direction of the first oblong hole 212b is the same as the length direction of the slide rail 220, and the length direction of the second oblong hole 214b is perpendicular to the length direction of the slide rail 220. Through the cooperation of the first oblong hole 212b and the second oblong hole 214b, the oblong holes have a margin, which can realize the fine adjustment of the movement of the ball tube 20 in the XY bidirectional direction, and prevent the installation position from changing when the ball tube 20 is replaced.

[0044] In some embodiments, see Figure 2 The pulley main board 211 is a flat plate structure, and the pulley main board 211 is arranged in a frame shape. Figure 2 The box form is shown.

[0045] Please refer to Figure 2 The pulley assembly 200 includes two first angle steels 230, the first angle steels 230 are fixedly connected to the moving part 222 of the slide rail 220, and the pulley main plate 211 is connected to the first angle steels 230. As a whole, the pulley main plate 211 is fixedly connected to the moving parts 222 of the two slide rails 220 through the two first angle steels 230.

[0046] In some embodiments, please refer to Figure 1 and Figure 2The pulley assembly 200 includes two second angle steels 240, the second angle steels 240 are connected to the fixing portion 221 of the slide rail 220, and the two second angle steels 240 are respectively connected to the two slide rails 220. The two slide rails 220 arranged in parallel and spaced apart form an opposite side and a diverging side, and the second angle steels 240 are located on the back side of the slide rail 220. Figure 2 As shown, the second angle steel 240 includes a vertical plate and a horizontal plate. The vertical plate of the second angle steel 240 is fixedly connected to the fixing portion 221 of the slide rail 220. The horizontal plate of the second angle steel 240 is installed on the top of the rack 100 by screws, so that the slide rail 220 is smoothly installed on the rack 100.

[0047] The above requires that all the connecting surfaces of the angle steel be smoothed, and the slide rails 220 be debugged and installed to ensure that the two slide rails 220 are parallel to each other and run smoothly.

[0048] The above definition is to overlap the mounting plate 310 on the rack 100. Under the condition that the rack 100 has a base 110, combined with reference Figure 1 , Figure 5 and Figure 6 The mounting plate 310 can be overlapped on the base 110, and the mounting plate 310 and the base 110 are connected by screws, and the screws are installed in the overlap area. A plurality of adjustment gaskets can be stacked between the overlap part of the mounting plate 310 and the base 110.

[0049] Alternatively, a transverse plate may be additionally provided on the rack 100, which is different from the base 110, and the mounting plate 310 may be overlapped and mounted on the transverse plate. However, it is recommended to overlap the mounting plate 310 on the rack 100, which can reduce the types and number of components.

[0050] In some embodiments, see Figure 6 The limit blocks 330 are arranged in an L shape. The limit assembly 300 includes four limit blocks 330. The four limit blocks 330 are respectively installed at the four corners of the mounting plate 310 by screws. The four limit blocks 330 smoothly limit the placement position of the ionization chamber body.

[0051] The limit block 330 can be made of polyoxymethylene resin material, which is also called POM material. Polyoxymethylene resin is soft in texture and can prevent adverse collisions with the ionization chamber body.

[0052] In some embodiments, see Figure 5 The rack 100 includes a base 110, a frame 120 and a corner bracket 130. The frame 120 is made of aluminum profiles. Four bases 110 are fixedly installed at the four corners of the bottom of the frame 120, and the corner bracket 130 is installed at the corner of the frame 120. Figure 5The figure shows that the angle bracket 130 is installed at multiple corner positions, and the angle bracket 130 can be replaced by an L-shaped connector. Accordingly, it is necessary to tap the aluminum profile to smoothly realize the screw connection at various locations.

[0053] Considering that the ionization chamber body is light in weight, the mounting plate 310 of the limiting assembly 300 can be made by bending a thin steel plate.

[0054] The three-dimensional divided frame 120 provided in this embodiment, in addition to the purchased finished products, other steel plate processed parts can be subjected to blue-white zinc plating anti-corrosion treatment, such as the first angle steel 230, the second angle steel 240 and the pulley main board 211.

[0055] Regarding the screw connection between the rack 100 and the lead floor, 8.8-grade M10 hexagon socket head screws may be used, and the screws may be fastened with thread locking glue to ensure that the rack 100 will not be disconnected within the approved load-bearing range.

[0056] Regarding the screw connections at the first angle steel 230 , the second angle steel 240 , the slide rail 220 , etc., hexagonal cylindrical head screws may be used, and the screws may be fastened with thread locking glue.

[0057] According to the actual use requirements, the slide rail 220 needs to be tested to withstand 4 times the load (180kg). In the selection of the slide rail 220, the load-bearing requirements must be met. In order to prevent the slide rail 220 from sliding when stationary, it is also necessary to add a limiter to it, and a lockable slide rail 220 is used.

[0058] Through a 4-fold load operation test, it is ensured that the slide rail 220 is sufficiently safe during operation, so that the ball tube 20 has no risk of falling off whether in a retracted state or when stretched to the maximum stroke.

[0059] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0060] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
