DETAILED DESCRIPTION
[0028] In order to enable those skilled in the art to better understand the technical solutions in the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the utility model.
[0029] It should be noted that the terms "upper" and "lower" indicate directions or positional relationships based on the directions or positional relationships shown in the auxiliary figures, and are only for the purpose of simplifying the description of the present invention, rather than indicating or implying that the device referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention. Specifically, in the present invention, the user's operating surface is the front, the direction toward the ground is the bottom, and conversely, the direction away from the ground is the upper, and other descriptions indicating directions are defined based on "upper" and "lower".
[0030] In various drawings of the present invention, for the convenience of illustration, some dimensions of structures or parts are exaggerated relative to other structural parts, and therefore, are only used to illustrate the basic structure of the subject matter of the present invention.
[0031] The utility model provides a wire-retracting and unreeling device 100 and a fixing structure 200 for the wire-retracting and unreeling device, wherein the wire-retracting and unreeling device 100 is used for storing sensor wires in a refrigeration equipment performance test, and the fixing structure 200 is used for storing the wire-retracting and unreeling device 100 as a whole.
[0032] like Figures 1 to 5 As shown, the wire-retracting and releasing device 100 includes a housing 10, a rotating shaft structure 20, and a locking structure 30. The housing 10 cooperates with the rotating shaft structure 20 and the locking structure 30 to realize the storage and arrangement of cables such as sensor cables. When the sensor cables are needed, the sensor cables are released. It can be understood that the wire-retracting and releasing device 100 of the utility model is also suitable for the storage of other cables.
[0033] The housing 10 includes a shell 11 and a cavity 12 formed in the shell 11 . Part of the structure of the rotating shaft structure 20 is located in the cavity 12 to protect the sensor line from being worn when in the storage state.
[0034] The housing 10 further includes an operating window 13 disposed on the side wall to communicate with the cavity 12 . The minimum radial dimension of the operating window 13 is larger than the dimension of the rotating shaft structure 20 in the cavity 12 , so as to facilitate winding the sensing wire around the rotating shaft structure 20 through the operating window 13 .
[0035] Preferably, if Figure 4 and Figure 5 As shown, a wire structure 15 is provided on the housing 10 , and the wire structure 15 is adjacent to the corresponding position of the window 13 , so as to facilitate guiding the sensing wire to the shaft structure 20 in the cavity 12 , thereby improving the efficiency of winding the sensing wire.
[0036] The wire structure 15 includes a pair of wire plates 151 fixed on the housing 11. A space is formed between the pair of wire plates 151 and the housing for the sensor wire to pass through. In order to prevent the sensor wire from falling out of the space, a limiting portion 152 extending toward the other wire plate 151 is provided at the end of at least one of the wire plates 151.
[0037] Furthermore, if Figures 1 to 4 As shown, the shaft structure 20 includes a shaft 21 for accommodating the sensor line and a turntable 22 fixed on the side of the shaft. The turntable 22 is rotatably connected to the housing 10 to fix the shaft structure 20 on the housing 10, so as to facilitate the rotation of the shaft structure 20 during the process of accommodating the sensor line.
[0038] Specifically, Figure 3 and Figure 4As shown, the length of the rotating shaft 21 is greater than the length of the housing 10. The rotating shaft 21 includes a first section 211 located inside the housing 10 and a second section 212 connected to the first section 211 and located outside the housing 10. The first section 211 is used to accommodate the sensing line, and the second section 212 is located outside the housing 10 to facilitate the rotation of the rotating shaft 21.
[0039] Preferably, in order to make the rotation of the rotating shaft 21 more convenient and labor-saving, the rotating shaft structure 20 also includes a handle 24 installed at one end of the rotating shaft 21. Specifically, the handle 24 is fixed to the end of the second section 212. The handle 24 is located on the outside of the outer shell 10. Specifically, the handle 24 includes an operating rod 241 installed on the outside of the second section 212 along the radial direction of the second section 212. By utilizing the principle of leverage, the rotating shaft 21 is driven to rotate by operating the operating rod 241, which saves time and effort.
[0040] Furthermore, two turntables 22 are provided and spaced apart at both ends of the first section 211 , so as to improve the strength of the combination of the turntable 22 and the housing 10 and improve the overall structural strength of the wire-reeling and -unreeling device 100 .
[0041] Furthermore, the shaft structure 20 further includes a plurality of hooks 23 disposed on the shaft 21 . Before winding the sensing wire, the sensing wire is first hung on the hooks 23 , and then the sensing wire is wound on the first section 211 adjacent to the hooks 23 .
[0042] Preferably, a plurality of the hooks 23 are arranged on the first section 211 at intervals along the radial direction of the first section 211 , and the hooks 23 are located at specific positions and will not affect the area of the winding sensing wire.
[0043] As a preferred embodiment of the present utility model, Figure 3 As shown, the rotating disk 22 of the rotating shaft structure 20 is plugged and fixed with the housing 10, and one of the rotating disk 22 and the housing 10 has a plug-in portion (not shown), and the other has a plug-in slot 14. In this embodiment, the plug-in direction is along the radial direction of the rotating shaft 21 to prevent the plug-in portion from falling off from the plug-in slot 14.
[0044] Preferably, the rotating disk 22 is provided with a plug-in portion, and of course, the plug-in portion can be the rotating disk 22 or a part of the rotating disk 22. The plug-in slot 14 is provided on the housing 10. In order to make the first section 211 of the rotating shaft 21 have a larger area for winding the sensing wire, the plug-in slot 14 is located at both ends of the housing 10 along the axial direction of the rotating shaft 21. In this embodiment, the diameter of the first section 211 is greater than the diameter of the second section 212, so that the outer wall of the plug-in slot 14 just abuts against the outer side of the first section 211, thereby increasing the contact area between the rotating shaft structure 20 and the housing 10 and improving the bonding strength between the rotating shaft structure 20 and the housing 10.
[0045] Of course, the plug-in portion may also be provided on the housing 10 , and the plug-in slot 14 may be formed on the circumferential surface of the turntable 22 , so as to realize the rotational connection between the shaft structure 20 and the housing 10 .
[0046] After the sensor line is stored, the rotating shaft 21 is prevented from rotating in the reverse direction. The utility model fixes the locking structure 30 and the handle 24 on the housing 10 to prevent the rotating shaft 21 from rotating in the reverse direction.
[0047] Specifically, Figures 1 to 4 As shown, the locking structure 30 includes a locking plate 31 fixed to one end of the housing 10 close to the handle 24, and at least one limiting hole 32 provided on the locking plate 31 for the handle 24 to be inserted. The handle 24 is inserted into the limiting hole 322 to prevent the rotating shaft 21 from continuing to rotate or rotating in the opposite direction.
[0048] When the locking disk 31 and the operating rod 241 both extend radially along the rotating shaft 21, in order to facilitate the handle 24 to be inserted into the limiting hole 32, the handle 24 also includes a limiting rod 242 movably connected to the operating rod 241, and the limiting rod 242 is preferably along the axial direction of the rotating shaft 21, that is, the limiting rod 242 is inserted into the limiting hole 32 along its axial direction.
[0049] The operating rod 242 is provided with a connecting hole (not shown) for the limiting rod 242 to pass through. The inner diameter of the connecting hole is slightly larger than the outer diameter of the limiting rod 242, so that the limiting rod 242 can move along the connecting hole to enable the limiting rod 242 to be inserted into or pulled out of the limiting hole. In order to prevent the limiting rod 242 from falling off in the connecting hole, the diameter of the end of the limiting rod 242 is larger than the inner diameter of the connecting hole.
[0050] In order to more conveniently insert the limiting rod 242 into the limiting hole 32, the locking disk 31 includes a sleeve 311 sleeved on the outside of the second section 212 and a spiral disk 312 connected to the end of the sleeve 311. The limiting hole 32 is evenly arranged on the spiral disk 312 along the circumference of the spiral disk 312. The sleeve 311 extends coaxially with the second section 212. The handle 24 is located on the side of the spiral disk 31 away from the first section 211, that is, the length of the second section 212 exceeds the length of the sleeve 311. The operating rod 241 and the housing 10 are respectively located on both sides of the spiral disk 312, and the operating rod 241 extends along the radial direction of the spiral disk 31, so as to facilitate the limiting rod 242 to be inserted into the limiting hole 32.
[0051] It is understandable that the locking plate 31 may also be located on one side of the rotating shaft 21 , which is also within the protection scope of this embodiment.
[0052] As another preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, the wire-retracting and -unwinding device 100 also includes a mounting seat 40 at one end of the housing 10 away from the locking structure 30, so as to facilitate the installation of the wire-retracting and -unwinding device 100 on the fixed structure 200, facilitate the storage of the wire-retracting and -unwinding device 100, and improve the neatness of the site for the refrigeration equipment performance test.
[0053] Preferably, the mounting seat 40 includes a first step 41 and a second step 42 connecting the first step 41 and the outer shell 10, the outer diameter of the first step 41 is larger than the outer diameter of the second step 42, and the wire retracting device 100 is installed on the fixed structure 200 by limiting the first step 41.
[0054] The second step 42 is fitted with the housing 10 by a concave-convex interference fit. One of the second step 42 and the housing 10 has a boss 43, and the other has a groove (not shown). In this embodiment, the boss 43 is provided on the second step 42, and the groove is provided on the housing 10.
[0055] The utility model also provides a fixing structure 200, such as Figure 6 and Figure 7 As shown, the above-mentioned wire-retracting and releasing device 100 is fixed on the fixed structure 200, and the fixed structure 200 is preferably a plate-shaped structure. The fixed structure 200 is provided with a slide groove 201 for the mounting seat 40 to slide, so as to change the position of the wire-retracting and releasing device 100, facilitate the storage of sensor wires of different heights, and improve the applicability of the wire-retracting and releasing device 100.
[0056] like Figure 7As shown, the radial interface of the slide groove 201 is C-shaped, that is, the opening of the slide groove 201 is provided with a pair of limiting plates 2013, the slide groove 201 includes a limiting groove 2011 located inside the fixed structure 200, and a neck groove 2012 connecting the limiting groove 2011 with the outside, the neck groove 2012 is formed between a pair of limiting plates 2013, and when the mounting seat 40 cooperates with the slide groove 201, the first step 41 is located in the limiting groove 2011, and the second step 42 is located in the neck groove 2012, and the limiting plate 2013 is restricted between the mounting seat 40 and the housing 10, thereby improving the bonding strength between the retractable wire device 100 and the fixed structure 200.
[0057] Preferably, the shape of the mounting seat 40 is the same as the cross section of the slide slot 201, which increases the contact area between the mounting seat 40 and the slide slot 201, improves the smoothness of sliding, and increases the bonding strength between the wire retracting and releasing device 100 and the fixed structure 200. In this embodiment, the mounting seat 40 is rectangular.
[0058] In this embodiment, Figure 2 and Figure 4 As shown, the wire retracting and releasing device 100 also includes an abutment structure 50 for preventing the mounting seat 40 from sliding relative to the slide groove 201, the abutment structure 50 includes an extension plate 51 extending from the side wall of the outer shell 20, a through hole 52 penetrating the extension plate 51 along the axial direction of the rotating shaft 21, and an abutment arm 53 movably connected to the extension plate 51 through the through hole 52, the abutment arm 53 is spirally matched with the extension plate 51 to change the distance between the abutment arm 53 and the fixed structure 200.
[0059] Preferably, if Figure 4 As shown, the abutment structure 50 also includes an abutment plate 54 located at the end of the abutment arm 53, and the area of the abutment plate 54 is larger than the area of the abutment arm 53. When the wire reeling device 100 is installed on the fixed structure 200, the abutment plate 54 abuts against the fixed structure 200, thereby increasing the contact area between the abutment structure 50 and the fixed structure 200.
[0060] Of course, the mounting seat 40 and the slideway 201 may also be limited by other means, such as concave-convex matching, which is also within the protection scope of this embodiment.
[0061] In summary, the wire retracting device 100 of the present invention cooperates with the housing 10, the shaft structure 20, and the locking structure 30, and a plurality of hooks 23 are arranged on the shaft 21, so that a plurality of sensor wires can be wound at the same time, thereby reducing the wear of the sensor wires and improving the sense of order in the test site management.
[0062] It should be understood that although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0063] The series of detailed descriptions listed above are only specific descriptions of feasible embodiments of the utility model and are not intended to limit the protection scope of the utility model. Any equivalent embodiments or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
