Description

Technical Field

[0001] This utility model relates to the field of support structure technology, and in particular to an easy-to-process detachable support track. Background Technology

[0002] Linear guides, also known as linear tracks, perform reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into various categories. Linear guides are usually composed of guide rails and moving modules. They have a higher rated load than lead screws and can be matched with various power modules to achieve high-precision linear motion under high load conditions.

[0003] A track support frame, with Chinese patent number CN218311987U, utilizes the telescopic setting of the guide rod at the top of the floating support block and the support tube, combined with the elasticity of the compression spring. This ensures good overall movement of the support frame while not hindering the suction cup from adsorbing and fixing the support frame onto the operating table under the action of the vacuum pump. This not only guarantees a good fixation effect for the support frame but also allows for free control of its movement, making it convenient for operators to adjust the working position of the milling cutter according to the specific size of the workpiece.

[0004] Traditional support rails mostly adopt an integrated molding design. The dimensions of integrated support rails are fixed. During transportation, excessively long or large rail structures will increase the difficulty of processing and molding, and also increase the occupancy rate of transportation space. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an easy-to-manufacture, detachable support rail, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an easy-to-process detachable support rail, including a first rail, a second rail detachably connected to the side end of the first rail, slots opened at both ends of the first rail and the second rail, a connecting block inserted into the slot at one end of the two second rails, a plurality of limiting holes are opened at equal intervals on both sides of the slot and the two ends of the connecting block, the limiting holes including a plurality of first screw holes opened on the side wall of the slot, a plurality of second screw holes symmetrically opened at both ends of the connecting block, and the first screw holes and the second screw holes correspondingly overlap, a screw is threaded into each set of limiting holes, and the screw is embedded in the slot, a limiting block is fixedly connected to the end of the screw away from the first screw hole, and the limiting block is embedded in the first screw hole.

[0007] As a further technical solution of this utility model, two sets of grooves are symmetrically opened at the upper and lower ends of the connecting block, and a compression spring is fixedly connected in each set of grooves.

[0008] As a further technical solution of this utility model, a retaining ball is fixedly connected to the end of the compression spring away from the groove, and arc-shaped limiting grooves corresponding to the retaining ball are symmetrically opened on the upper and lower walls of the slot, and the retaining ball engages with the limiting groove.

[0009] As a further technical solution of this utility model, the surface area of ​​the ball being held in the limiting groove is less than half of the surface area of ​​the ball.

[0010] As a further technical solution of this utility model, a sealing ring is fixedly connected to the outer ring of the limiting block, and a protective film is glued to the end of the limiting block away from the screw.

[0011] As a further technical solution of this utility model, the protective film and the limiting block are coated with glue at one end, and release paper is adhered to the surface of the glue.

[0012] As a further technical solution of this utility model, both ends of the connecting block are fixedly connected with wave spring plates, and the two wave spring plates respectively abut against the inner wall of the corresponding slot.

[0013] This utility model provides an easy-to-manufacture, detachable support rail, which has the following advantages compared with the prior art: This design presents an easily manufactured, detachable support rail. The slots at one end of the first and second rails, close to each other, are respectively engaged with the two ends of a connecting block, thus securing the connecting block within the first and second rails. At this point, the first and second rails are joined together. During the process of the connecting block being inserted into its corresponding slot, the retaining balls at both ends of the connecting block are first compressed and retracted into the grooves. Upon entering the slot, the retaining balls, passing through the limiting groove, are automatically engaged into the corresponding limiting groove by the compression spring force, thus pre-locking the connecting block and the slot. After the first and second rails are engaged with the connecting block, the ends of the connecting block... The wave spring sheets abut against the inner walls of the corresponding slots. When the first and second tracks experience slight displacement due to vibration, the wave spring sheets absorb energy through elastic deformation, reducing the impact on the connecting structure. After the multiple first screw holes on the first and second tracks coincide with the multiple second screw holes on the connecting block, the screws with limit blocks are inserted into the corresponding set of limit holes and tightened to fix them. After fixing, the limit blocks are inserted into the first screw holes, without affecting the use of the support tracks. The above technical solution enables the disassembly and assembly of multiple short support tracks, reducing both the processing difficulty and the space occupancy rate during transportation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-2 This utility model provides a technical solution for an easy-to-process detachable support track: it includes a first track 1, a second track 2 detachably connected to the side of the first track 1, slots 3 are provided at both ends of the first track 1 and the second track 2, a connecting block 4 is inserted into the slot 3 at one end of the two second tracks 2, and multiple sets of limiting holes are provided at equal distances between the two side walls of the slot 3 and the two ends of the connecting block 4. The limiting holes include multiple first screw holes 6 provided on the side walls of the slot 3, and multiple second screw holes 7 are symmetrically provided at both ends of the connecting block 4, and the first screw holes 6 and the second screw holes 7 correspond to and overlap each other. A screw 5 is threaded into each set of limiting holes, and the screw 5 is embedded in the slot 3. A limiting block 12 is fixedly connected to the end of the screw 5 away from the first screw hole 6, and the limiting block 12 is embedded in the first screw hole 6. Please see Figure 3 The connecting block 4 has two sets of grooves 9 symmetrically opened at the upper and lower ends. Each set of grooves 9 is fixedly connected to a compression spring 10. The end of the compression spring 10 away from the groove 9 is fixedly connected to a retaining ball 8. The upper and lower walls of the slot 3 are symmetrically opened with arc-shaped limiting grooves 11 corresponding to the retaining ball 8. The retaining ball 8 is engaged with the limiting groove 11. The surface area of ​​the retaining ball 8 in the limiting groove 11 is less than half of the surface area of ​​the retaining ball 8.

[0018] Please see Figures 3-4A sealing ring 13 is fixedly connected to the outer ring of the limiting block 12. A protective film 14 is glued to the end of the limiting block 12 away from the screw 5. Glue is applied to the end of the protective film 14 that is attached to the limiting block 12, and release paper 15 is glued to the surface of the glue. Wave spring plates 16 are fixedly connected to both ends of the connecting block 4, and the two wave spring plates 16 respectively abut against the inner wall of the corresponding slot 3.

[0019] The working principle of this utility model is as follows: The slots 3 of the first track 1 and the second track 2, which are close to each other, are respectively locked onto the two ends of the connecting block 4, thereby locking the connecting block 4 into the first track 1 and the second track 2. At this time, the first track 1 and the second track 2 are in a spliced ​​state. During the process of the connecting block 4 being locked into the corresponding slot 3, the locking balls 8 on the upper and lower ends of the connecting block 4 are first compressed and contracted into the grooves 9. When locked into the slot 3, after passing through the limiting groove 11, the locking balls 8 are automatically locked into the corresponding limiting groove 11 by the elastic force of the compression spring 10. In this way, the connecting block 4 and the slot 3 are pre-locked to prevent misalignment when the first track 1, the second track 2 and the connecting block 4 are fixed with screws 5 later. This would prevent the first screw hole 6 and the second screw hole 7 on each set of limiting holes from not coinciding, and the area of ​​the retaining ball 8 that is inserted into the limiting groove 11 is less than half the surface area of ​​the retaining ball 8. Therefore, when disassembling the connecting block 4, the retaining ball 8 can be pulled out of the limiting groove 11 by force. After the first track 1 and the second track 2 are respectively engaged with the connecting block 4, the wave spring plates 16 at both ends of the connecting block 4 respectively When the first track 1 and the second track 2 experience slight displacement due to vibration, the wave spring sheet 16 absorbs energy through elastic deformation, reducing the impact on the connecting structure. After the multiple first screw holes 6 on the first track 1 and the second track 2 correspond to the multiple second screw holes 7 on the connecting block 4, the screw 5 with the limit block 12 is inserted into the corresponding set of limit holes and tightened to fix it. After fixing, the limit block 12 is inserted into the first screw hole 6, and the surface of the limit block 12 and the inner wall of the first screw hole 6 are sealed. The ring 13 is sealed to prevent water and dust from entering the gap. Finally, a protective film 14 matching the surface of the limit block 12 is used. After peeling off the release paper 15 on the glue-coated side, the protective film 14 is glued to the surface of the limit block 12 to provide isolation and protection. This prevents the slider on the support rail from moving back and forth during operation and causing wear on the surface of the limit block 12. The above technical solution allows for the disassembly and assembly of multiple short support rails, which reduces the processing difficulty and the space occupied during transportation.

[0020] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
