Description

Technical Field

[0001] This utility model relates to the field of table tennis table technology, and in particular to a novel table tennis table. Background Technology

[0002] Table tennis is a popular ball sport played on a table. With rising living standards, people are paying more attention to their health, often through exercise, and table tennis has become one of the most common sports, resulting in a huge demand for table tennis tables.

[0003] The most widely used ping-pong tables are currently of the split type, consisting of two relatively square 1525mm x 1370mm tabletops, assembled into a standard 1525mm x 2740mm ping-pong table. Both tabletops are supported by a square tubular support frame to maintain the tabletop at a standard height of 760mm. The support frame consists of four legs and a tabletop support. Currently, the two tabletops are secured by hand-tightened screws with pressure plates on the net frame. However, this method is prone to loosening during use, causing the two tabletops to separate and resulting in a table length exceeding the standard 2740mm. Size and net misalignment can also cause the net to sag, resulting in the net not being sewn to the center line of the table and the net being lower than the standard height of 152mm. Furthermore, most mainstream table tennis tables use a beaded system for the net cord. After tightening the cord, the bead is secured to the net frame's locking mechanism. The bead and cord are usually connected by a key ring, which is very easy to damage and detach. The bead itself is also easily broken. The connection between the bead and the net frame's locking mechanism is not secure, making it prone to slippage. The cord is only positioned by a groove on the inner shaft of the net frame's uprights, making it easy for the cord to slip out. In short, loose and detaching net cords are a common problem with many table tennis table net frames.

[0004] Therefore, we propose a new type of ping-pong table. Utility Model Content

[0005] The main purpose of this utility model is to propose a new type of ping-pong table that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a novel ping-pong table, comprising: Two ping-pong tabletops, each with a table leg fixedly installed at its bottom end, and each with a tabletop square tube fixedly connected to its bottom end, with two slots symmetrically arranged between the two tabletop square tubes; Two space frame components, each of which is respectively disposed in two slots; Two space frame uprights are respectively installed at the top of the space frame assembly; A ball net, which is fixedly connected between two net frame uprights; A tensioning member, which is fixedly mounted on one of the space frame components; The net rope has one end fixedly connected to a net frame pole, and the other end passes through the through hole in the net and another net frame pole in sequence before being fixedly connected to the tensioning rope. The two square tubes on the tabletop are fixedly connected by wing bolts.

[0007] As a further description of the above technical solution, a rope guide tube is fixedly connected to the upper end of one side of the net frame upright where the rope tensioning member is located, for the net rope to pass through.

[0008] As a further description of the above technical solution, the rope tightening component adopts a ratchet locking knob for tightening or loosening the net rope.

[0009] As a further description of the above technical solution, the countertop square tube includes a U-shaped square tube and two connecting square tubes, and both connecting square tubes are provided with through holes.

[0010] As a further description of the above technical solution, the U-shaped square tube is fixedly connected to the two connecting square tubes at right angles. The U-shaped square tube and the two connecting square tubes are integrally formed. The two tabletop square tubes are symmetrically distributed. The slot is the space formed between the connecting square tube on one tabletop square tube and the connecting square tube on the other tabletop square tube. The wing bolt is adapted to the through hole.

[0011] As a further description of the above technical solution, the space frame assembly includes a U-shaped clamping plate, a first fastening screw is threaded to one side of the bottom end of the U-shaped clamping plate, a second fastening screw is threaded to the other side of the bottom end of the U-shaped clamping plate, a rubber pad is fixedly connected to the top of the first fastening screw, a through hole is opened on one side of the U-shaped clamping plate, and a third fastening screw is threaded to the inside of the through hole.

[0012] As a further description of the above technical solution, the U-shaped card plate is adapted to the card slot and is inserted into the card slot to engage with the side of the ping-pong table.

[0013] As a further description of the above technical solution, the upright of the net frame is located at the top of the U-shaped plate, the second fastening screw passes through the U-shaped plate and is threadedly connected to the upright of the net frame, and the third fastening screw passes through the through hole and is threadedly connected to the table tennis table.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Stable tabletop connection: The two tabletop square tubes are fixed by wing bolts and through holes. Compared with the traditional hand-tightening screw and clamp fixing method, after tightening, the two tabletops can be tightly attached and are not easy to separate due to collision, ensuring that the table length meets the standard size.

[0015] 2. Reliable fixation of the net frame: After the U-shaped card plate of the net frame assembly is inserted into the slot, it is pressed against the bottom of the table board by the first fastening screw (with rubber pad), and the third fastening screw is threaded to the table board, so as to achieve double fixation in both the horizontal and vertical directions, and prevent the net frame from loosening and causing the net to tilt.

[0016] 3. The net frame uprights are fixed to the U-shaped clamps by the second fastening screws, which further enhances the stability of the net and prevents the net from falling below the standard height.

[0017] 4. Durable and Tight Net Rope: The ratchet locking knob is used as the tightening component. The net rope is steplessly tightened through the engagement of gears and pawls. Compared with the traditional chain bead buckle method, it is not easy to fall off or break. The tension of the net rope can be precisely adjusted to ensure that the net always remains taut.

[0018] 5. The guide tube guides the net rope through, preventing the net rope from slipping out of the upright groove and improving the reliability of the positioning in the seam. Attached Figure Description

[0024] Please see Figure 1-8 This utility model provides a technical solution: a novel ping-pong table, comprising: Two ping-pong tabletops 1, each with table legs 2 fixedly mounted at its bottom, and each with a tabletop square tube 3 fixedly connected to its bottom. During installation, the two tabletops 1 are placed close together in a mirror image arrangement, as are the two tabletop square tubes 3. Each tabletop square tube 3 comprises a U-shaped square tube 31 and two connecting square tubes 32, which are fixedly connected at right angles and are integrally formed. Each connecting square tube 32 has a through hole 33. One of the tabletops... A groove 4 is formed between the connecting square tube 32 on the square tube 3 and the corresponding connecting square tube 32 on the other tabletop square tube 3. The two tabletop square tubes 3 are fixedly connected by a wing bolt 10. The wing bolt 10 is adapted to the through hole 33. During installation, the two wing bolts 10 are passed through the through holes 33 on the connecting square tubes 32 distributed on both sides of the ping-pong table 1 in turn, and then tightened to make the two ping-pong table 1 stick together tightly and not easily separated due to collision. Two net frame components 5 are respectively set in two slots 4. Each net frame component 5 includes a U-shaped card plate 51, which is adapted to the slot 4. The height of the U-shaped slot of the U-shaped card plate 51 is adapted to the thickness of the table tennis table 1, that is, the U-shaped card plate 51 can be snapped onto the table tennis table 1. The top of each U-shaped card plate 51 is provided with a net frame upright 6. A net 7 is fixedly connected between the two net frame uprights 6. A first fastening screw 52 is threaded to one side of the bottom of the U-shaped card plate 51. A rubber pad 54 is fixedly connected to the top of the first fastening screw 52. A second fastening screw 53 is threaded to the other side of the bottom of the U-shaped card plate 51. The second fastening screw 53 passes through the U-shaped card plate 51 and is threaded to the net frame upright 6. A through hole 55 is opened on one side of the U-shaped card plate 51. A third fastening screw 56 is threaded inside the through hole 55. During installation, first insert the U-shaped clamp 51 into the groove 4 from the side until the U-shaped clamp 51 is engaged with the table tennis table 1. Then, rotate the first fastening screw 52 to raise the rubber pad 54 until the rubber pad 54 is firmly pressed against the bottom of the table tennis table 1. Then, use the third fastening screw 56 to pass through the through hole 55 and connect it to the table tennis table 1 with a thread. This allows the U-shaped clamps 51 of the two net frame components 5 to be restricted into the two grooves 4 formed between the two table surface square tubes 3. The first fastening screw 52 and the third fastening screw 56 achieve horizontal and vertical fixation of the net frame components 5, resulting in better fixation. The net frame upright 6 for installing the net 7 is fixed to the U-shaped clamp 51 by the second fastening screw 53, thus ensuring that the net 7 is not easily knocked off. The tensioning element 8 is used to tighten or loosen the net rope 9. The tensioning element 8 is fixedly installed on one side of one of the U-shaped clamps 51. Net rope 9, one end of which is fixedly connected to a net frame pole 6, and the other end passes through the through hole on the net 7 and another net frame pole 6 in sequence before being fixedly connected to the tensioning rope member 8. A guide tube 11 is fixedly connected to the upper end of one side of the net frame pole 6 where the tensioning rope member 8 is located, for the net rope 9 to pass through.

[0025] To further explain, the tightening mechanism uses a ratchet locking knob, which is a known prior art. This locking knob includes a pawl assembly and a locking cap. The pawl assembly includes a fixed disc, a pawl, and a torsion spring. A first opening is formed on the fixed disc. The lower part of the pawl is rotatably fitted onto the outside of a fixed shaft. The fixed shaft is fixed below the fixed disc and parallel to it. The top of the pawl protrudes through the first opening. A torsion spring is fitted onto the outside of the fixed shaft and is fixedly connected to the pawl. The torsion spring is used to make the pawl tightly adhere to one side of the first opening. The locking cap has a hollow cylindrical structure with an open bottom. The central axis of the locking cap coincides with the central axis of the fixed disc. A gear is provided on the inner side of the top of the locking cap, which engages with the top of the pawl. The specific workflow is as follows: Initial installation position: The pawl engages with the lever switch shaft, allowing it to rotate around the lever switch. The pawl is subjected to the torsion force of the torsion spring and the overall force of the rear compression spring. The first opening is the pawl's working position, and this is the initial position. Tightening the cap: The cap rotates clockwise, causing the inner elastic cantilever to strike the pawl. The pawl disengages from the second opening side and, under the force of the rear compression spring, springs back to the first opening side, where it aligns with the inner gear of the cap. Continuing to rotate downwards (refer to Figures 1 and 2), the inner gear of the cap engages with the pawl, tightening the cap. Unlocking the cap: Pulling the lever switch disengages the pawl from its engaged state. Under the force of the torsion and compression springs, it enters the second opening, completely disengaging the inner gear of the cap. The cap is then rotated counter-clockwise. This constitutes one complete tightening and loosening operation of the knob.

[0026] To further explain, the net rope 9 is fixedly connected to the locking cover on the ratchet locking knob, and the fixing plate is fixedly installed on the U-shaped card plate 51. When the locking cover is turned tightly, it will pull the net rope 9 to keep it taut, so that the net 7 can be kept at an appropriate height and will not collapse due to the loosening of the net rope 9.

[0027] It should be noted that this utility model is a new type of ping-pong table. During installation, the two ping-pong tabletops 1 are first placed close together in a mirror image, aligning the connecting square tubes 32 of the square tubes 3 on both sides of the table surface to form two slots 4. Then, the wing bolts 10 are passed through the through holes 33 of the connecting square tubes 32 on both sides and manually tightened to ensure that the ping-pong tabletops 1 are tightly connected. For the net frame installation, the U-shaped clamping plate 51 is inserted from the side of the slot 4 until it is clamped onto the side of the ping-pong tabletop 1 (the U-shaped groove is adapted to the thickness of the tabletop). The first fastening screw 52 is rotated clockwise to raise the rubber pad 54 and press it tightly against the bottom of the ping-pong tabletop 1, fixing the lateral position of the U-shaped clamping plate 51. Then, the third fastening screw 56 is passed through the through hole 55 of the U-shaped clamping plate 51 and threadedly connected to the ping-pong tabletop 1 to fix the longitudinal position of the U-shaped clamping plate 51. First, place the net frame upright 6 on the top of the U-shaped clamp 51. Then, use the second fastening screw 53 to pass through the U-shaped clamp 51 and thread it onto the net frame upright 6 to fix its position. Next, install the net 7 and net rope 9 by fixing the net 7 between the two net frame uprights 6 (the specific fixing method can use existing conventional connection methods, such as hooks, bolts, etc.). Then, fix one end of the net rope 9 to one side of the net frame upright 6, and pass the other end through the through hole on the net 7 and the other side of the net frame upright 6. Guided by the rope guide tube 11, it connects to the locking cap of the tensioning component 8 (ratchet locking knob). Rotate the locking cap clockwise to tighten the net rope through the engagement of the gear and pawl until the net 7 reaches the appropriate tension. To loosen, pull the lever switch to disengage the pawl from the gear, and then rotate the cap counterclockwise. Compared with existing new ping-pong tables, this utility model solves the problems of easy loosening, net tilting and falling, and loose and falling net ropes in traditional ping-pong tables by optimizing the tabletop connection, net frame fixing and net rope tensioning structure. It has the advantages of stable connection, convenient adjustment and high reliability.
