Description

Technical Field

[0001] This utility model relates to the field of filing cabinet technology, and in particular to a filing cabinet drawer guide rail support assembly. Background Technology

[0002] A filing cabinet is a type of office furniture used to preserve and store archival materials. Filing cabinets typically refer to cabinets with doors and lids, used to store documents, data, archives, and other items for easy classification, organization, and preservation. They are generally made of wood or metal, and some are even modular, consisting of separate boxes that can be stacked to form a cabinet.

[0003] Existing filing cabinets do not have a real-time limiting function when the drawers are pulled out. The guide rail support components they use are common rails on the market. These rails can only prevent the drawers from sliding out, but cannot limit the drawers. In order to realize the real-time limiting function of the filing cabinet drawers, we propose a filing cabinet drawer guide rail support component. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drawer guide rail support assembly for filing cabinets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drawer slide support assembly for a filing cabinet includes a filing cabinet drawer, a back panel fixedly installed on the outer side of the drawer, and slide support assemblies on both sides of the drawer. A limit assembly is provided on the right side of the slide support assembly. The limit assembly includes a fixed cylinder, a plug-in limit post slidably installed on the inner side of the fixed cylinder, a compression spring fixedly connected between the plug-in limit post and the inner wall of the fixed cylinder, a pull rope fixedly connected to the end of the plug-in limit post, a guide cylinder provided on the side of the fixed cylinder, the guide cylinder passing through to the outer side of the back panel, and a sliding column slidably plugged into the outer end of the guide cylinder.

[0007] Furthermore, the fixed cylinder slides through to the inside of the filing cabinet drawer, and a screw-connected cylinder is screwed to the inner end of the fixed cylinder, with the end of the screw-connected cylinder rotatably connected to the guide cylinder.

[0008] Furthermore, an operating handle is fixedly installed on the outer end of the sliding column.

[0009] Furthermore, the guide rail support assembly includes a track and a retaining rail. The retaining rail is slidably engaged with the outside of the track. Several limiting circular holes are evenly distributed on the side of the track. The end of the fixed cylinder is fixedly connected to the retaining rail. The insertion limiting post slides through to the inside of the retaining rail.

[0010] Furthermore, the outer diameter of the insertion limiting post is adapted to the inner diameter of the limiting circular hole.

[0011] Furthermore, several ball bearings are evenly distributed on the upper and lower sides of the track, a mounting side plate is fixedly connected to the side of the track, and several mounting ear plates are fixedly connected to the side of the rail. The mounting ear plates are screwed to the side of the filing cabinet drawer.

[0012] Furthermore, a handle is fixedly installed on the outer side of the back plate.

[0013] Compared with related technologies, the drawer guide rail support assembly for filing cabinets proposed in this utility model has the following beneficial effects:

[0014] In this utility model, a drawer guide rail support assembly for a filing cabinet utilizes a limiting component. A compression spring within the limiting component provides a restoring force, causing the insertion limiting post to engage with a limiting hole on the side of the rail. This prevents relative sliding between the drawer rail and the rail mounted on the filing cabinet, thus limiting the drawer's position. To release this limitation, the sliding post at the outer end of the guide cylinder is pulled, causing the pull rope to extend outwards. This, in turn, disengages the insertion limiting post from the limiting hole on the side of the rail, allowing relative sliding between the rail and the drawer rail. This releases the drawer's position. The limiting component of this utility model is simple and compact, providing real-time drawer limiting and easy-to-release operation, making it highly practical.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figure 1-7 A filing cabinet drawer guide rail support assembly includes a filing cabinet drawer 1, a handle 3 fixedly installed on the outer side of a back panel 2, a back panel 2 fixedly installed on the outer side of the filing cabinet drawer 1, guide rail support assemblies 4 on both sides of the filing cabinet drawer 1, and a limit assembly 5 on the right guide rail support assembly 4; the limit assembly 5 includes a fixed cylinder 51, a plug-in limit post 53 slidably installed on the inner side of the fixed cylinder 51, a compression spring 52 fixedly connected between the plug-in limit post 53 and the inner wall of the fixed cylinder 51, a pull rope 54 fixedly connected to the end of the plug-in limit post 53, a guide cylinder 56 provided on the side of the fixed cylinder 51, the guide cylinder 56 passing through to the outer side of the back panel 2, and a sliding column 57 slidably plugged into the outer end of the guide cylinder 56.

[0025] In this method, the guide rail support assembly 4 includes a rail 41 and a retaining rail 42. The retaining rail 42 is slidably engaged with the outside of the rail 41. Several limiting circular holes 46 are evenly distributed on the side of the rail 41. The end of the fixing cylinder 51 is fixedly connected to the retaining rail 42. The insertion limiting post 53 slides through to the inside of the retaining rail 42. The outer diameter of the insertion limiting post 53 is adapted to the inner diameter of the limiting circular hole 46.

[0026] With the above-mentioned setup, during use, the rebound force provided by the compression spring 52 can drive the insertion limiting post 53 to insert into the limiting round hole 46 opened on the side of the track 41, thereby realizing the sliding limiting function of the track 41 and the locking rail 42. Since the limiting round holes 46 are evenly distributed along the side of the track 41, no matter where the filing cabinet drawer 1 slides the locking rail 42 to, there is a corresponding limiting round hole 46 that engages with the insertion limiting post 53, so that the filing cabinet drawer 1 can achieve a stable limiting function when it slides out to any position.

[0027] In this configuration, several ball bearings 45 are evenly distributed on the upper and lower sides of the track 41, and a mounting side plate 43 is fixedly connected to the side of the track 41. Several mounting ear plates 44 are fixedly connected to the side of the rail 42, and the mounting ear plates 44 are screwed to the side of the filing cabinet drawer 1.

[0028] By setting the ball bearing 45 as described above, the sliding friction between the track 41 and the guide rail 42 is reduced, thus making the drawer 1 of the filing cabinet smoother when it is pulled out.

[0029] In this method, the fixing cylinder 51 slides through to the inside of the filing cabinet drawer 1, and a screw-connected cylinder 55 is screwed onto the inner end of the fixing cylinder 51. The end of the screw-connected cylinder 55 is rotatably connected to the guide cylinder 56.

[0030] With the above-described configuration, the sliding rail 42 on the side of the filing cabinet drawer 1 has a pre-drilled hole on the inside of the drawer 1 that matches the fixed cylinder 51. Simultaneously, a pre-drilled hole on the back plate 2 that matches the guide cylinder 56 is provided. The fixed cylinder 51, fixedly connected to the sliding rail 42, is then inserted into the pre-drilled hole. Subsequently, the guide cylinder 56 is inserted from the inside of the filing cabinet drawer 1 through the pre-drilled hole on the back plate 2 to the outside. The pull rope 54 inside the fixed cylinder 51 is led out and passed sequentially through the screw-in cylinder 55 rotatably mounted at the end of the guide cylinder 56. The pull rope 54 then passes through the guide cylinder 56. 6. Pass through to the outer end of its guide cylinder 56, and then screw the screw-in cylinder 55 onto the end of the fixed cylinder 51, thus realizing the connection between the guide cylinder 56 and the fixed cylinder 51. Then, pull the pull rope 54 out a section and fix the outer end of the pull rope 54 to the slide column 57. Then, insert the slide column 57 into the guide cylinder 56 to complete the installation. The joint rotatably set at the end of the guide cylinder 56 is the screw-in cylinder 55, which provides convenience for the installation of this limiting component 5, makes this limiting component 5 feasible in actual installation, and enhances its practicality.

[0031] In this configuration, an operating handle 58 is fixedly installed on the outer end of the sliding column 57.

[0032] The above-described configuration of the control dial 58 facilitates the movement of the sliding column 57 via the control dial 58.

[0033] The working principle of the drawer slide support assembly for a filing cabinet provided by this utility model is as follows:

[0034] When in use, to pull out the filing cabinet drawer 1, pull the operating handle 58 to pull the sliding column 57 out to the outer end of the guide cylinder 56. This will cause the pull rope 54 to pull the inner insertion limit post 53 out of the limit hole 46 on the side of the track 41, releasing the relative sliding freedom between the track 41 and the locking rail 42. At this time, the filing cabinet drawer 1 can be pulled out. When it is pulled out to a certain extent, release the operating handle 58. Under the action of the spring 52, the insertion limit post 53 will be inserted into the limit hole 46 on the side of the track 41, realizing the limiting function of the filing cabinet drawer 1 at that position. Unlocking and limiting only require operating the outer operating handle 58, which is convenient for daily use and highly practical.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
