Abstract
Description
Technical Field
[0001] This utility model relates to the field of seat technology, and in particular to a tubular connection structure and a seat. Background Technology
[0002] In related technologies, the front and rear frames of racing simulator seats are usually made of standard round tubing and connected and fixed by screws or bolts inserted into corresponding connecting holes. This cannot meet the market's demand for diverse shapes of simulator seat frames. In particular, when the front and rear frames use non-shaped tubing, the connection difficulty is increased. In addition, the use of bolts or screws only supports fixed gear adjustment and cannot meet the needs of fine distance adjustment, thus reducing the user experience. Utility Model Content
[0003] The purpose of this utility model is to provide a pipe connection structure and a seat, which facilitates the connection of irregular pipes and enables fine adjustment.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] A pipe fitting connection structure for connecting a first pipe and a second pipe, wherein the inner diameter of the first pipe is larger than the outer diameter of the second pipe, the pipe fitting connection structure is disposed between the first pipe and the second pipe, and the pipe fitting connection structure includes:
[0006] A locking block, wherein a first through hole is provided on the locking block;
[0007] A sliding block, wherein the sliding block is disposed on one side of the locking block;
[0008] A locking component, one end of which can pass through the first through hole and connect to the sliding block, wherein the outer diameter of the locking component is smaller than the diameter of the first through hole;
[0009] When the locking member rotates, it can pull the sliding block to move relative to the locking block, so that one of the locking block and the sliding block presses against the inner wall of the first tube, and the other of the locking block and the sliding block presses against the outer wall of the second tube.
[0010] In some embodiments, the locking block is provided with a first inclined surface, and the sliding block is provided with a second inclined surface that abuts against the first inclined surface; the sliding block is provided with a screw hole, and one end of the locking member can pass through the first through hole and be screwed into the screw hole.
[0011] In some embodiments, the pipe connection structure further includes a fixing block, which abuts against the side of the locking block away from the sliding block, and the fixing block is provided with a second through hole; one end of the locking member can pass through the second through hole and the first through hole in sequence and be screwed into the screw hole.
[0012] In some embodiments, the locking block is provided with a third inclined surface, which is disposed on opposite sides of the sliding block along with the first inclined surface, and the fixing block is provided with a fourth inclined surface that abuts against the third inclined surface.
[0013] In some embodiments, the first inclined surface and the third inclined surface gradually converge from the bottom to the top of the locking block.
[0014] In some embodiments, the top of the sliding block and the top of the fixing block are provided with a first structure that abuts against a portion of the inner contour of the first tube, and the bottom of the locking block is provided with a second structure that abuts against a portion of the outer contour of the second tube.
[0015] In some embodiments, the fixed block has a protruding edge on the side opposite to the sliding block, and the protruding edge can abut against the end of the first tube.
[0016] In some embodiments, the second perforation is a stepped perforation.
[0017] In some embodiments, the locking element is a bolt;
[0018] Alternatively, the locking element includes a connecting rod and a cam handle, the cam handle being rotatable at a first end of the connecting rod, and the second end of the connecting rod being connectable to the sliding block.
[0019] A seat is also provided, which includes a front frame, a rear frame, and a tubular connection structure as described above. One of the front frame and the rear frame is provided with the first tube, and the other is provided with the second tube. The first tube is inserted into the second tube, and the tubular connection structure is provided between the first tube and the second tube.
[0020] In some embodiments, at least one of the first tube and the second tube is a non-standard tube.
[0021] The beneficial effects of this utility model are:
[0022] By rotating the locking component, the sliding block and the locking component move relative to each other, allowing one of the locking block and the sliding block to press against the inner wall of the first tube, and the other to press against the outer wall of the second tube. The frictional force of the mutual pressing fixes the first and second tubes together, thus eliminating the need to consider the shapes of the first and second tubes when connecting and fixing them, reducing the difficulty of connection. In addition, since the above-mentioned tube connection structure is set between the first and second tubes, when the locking component is rotated in the opposite direction to disengage the locking block and the sliding block from the first and second tubes respectively, the insertion depth of the first and second tubes can be adjusted. After adjustment, the locking component can be rotated again at any position to lock, achieving stepless adjustment and meeting the needs of fine adjustment. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0035] like Figures 1 to 6As shown, this application provides a seat, which may be, but is not limited to, a racing simulator seat. The seat includes a front frame 10 and a rear frame 20, wherein one of the front frame 10 and the rear frame 20 is provided with a first tube 1, and the other is provided with a second tube 2. At least one of the first tube 1 and the second tube 2 can be a shaped tube. It should be noted that shaped tubes are a common description in the prior art, and they can be divided into different types according to the radial cross-section of the tube, without limitation. The inner diameter of the first tube 1 is larger than the outer diameter of the second tube 2, so that the second tube 2 can be inserted into the first tube 1. The seat also includes a tube connection structure, which is designed with... The fitting is placed between the first pipe 1 and the second pipe 2 to connect the first pipe 1 and the second pipe 2 and fix the first pipe 1 and the second pipe 2. The pipe fitting connection structure includes a locking block 3, a sliding block 4 and a locking member 6. The locking block 3 is provided with a first through hole 31, and the sliding block 4 is provided on one side of the locking block 3. One end of the locking member 6 can pass through the first through hole 31 and connect with the sliding block 4. The outer diameter of the locking member 6 is smaller than the diameter of the first through hole 31. When the locking member 6 rotates, it can pull the sliding block 4 to move relative to the locking block 3, so that one of the locking block 3 and the sliding block 4 squeezes the inner wall of the first pipe 1, and the other of the locking block 3 and the sliding block 4 squeezes the outer wall of the second pipe 2.
[0036] By setting the aforementioned pipe connection structure between at least one shaped pipe (first pipe 1) and at least one shaped pipe (second pipe 2), rotating the locking member 6 causes the sliding block 4 and the locking member 6 to move relative to each other. This allows one of the locking block 3 and the sliding block 4 to press against the inner wall of the first pipe 1, while the other presses against the outer wall of the second pipe 2. The frictional force of the mutual pressing then fixes the first pipe 1 and the second pipe 2. Therefore, when connecting and fixing the first pipe 1 and the second pipe 2, there is no need to consider the shape of the first pipe 1 and the second pipe 2, reducing the connection difficulty. Furthermore, since the aforementioned pipe connection structure is set between the first pipe 1 and the second pipe 2, when the locking member 6 is rotated in the opposite direction, causing the locking block 3 and the sliding block 4 to disengage from the first pipe 1 and the second pipe 2 respectively, the insertion depth of the first pipe 1 and the second pipe 2 can be adjusted. After adjustment, the locking member 6 can be rotated again at any position to lock, achieving stepless adjustment and meeting the needs of fine adjustment.
[0037] like Figure 4 As shown, in the current embodiment, the locking block 3 is provided with a first inclined surface 32, the sliding block 4 is provided with a second inclined surface 41 that abuts against the first inclined surface 32, the sliding block 4 is provided with a screw hole 42, one end of the locking member 6 passes through the first through hole 31 and is screwed into the screw hole 42, so that when the locking member 6 is screwed, the locking block 3 and the sliding block 4 are misaligned and abut against the first tube 1 and the second tube 2 respectively, thereby connecting the first tube 1 and the second tube 2.
[0038] In addition, by using the locking element 6 screwed onto the sliding block 4, it is easy to disassemble and replace when maintenance or replacement is required, thereby reducing maintenance costs.
[0039] like Figure 3 As shown, to ensure the stability of the locking block 3 and the sliding block 4, the pipe connection structure also includes a fixing block 5. The fixing block 5 abuts against the side of the locking block 3 away from the sliding block 4. The fixing block 5 is provided with a second through hole 51. The end of the locking member 6 can pass through the second through hole 51 and the first through hole 31 in sequence and be screwed into the screw hole 42. The locking block 3 is provided with a third inclined surface 33. The third inclined surface 33 and the first inclined surface 32 are provided on opposite sides of the sliding block 4. The fixing block 5 has a fourth inclined surface 52 that abuts against the third inclined surface 33. The first inclined surface 32 and the third inclined surface 33 gradually approach each other from the bottom to the top of the locking block 3. Thus, when the locking member 6 is tightened, the sliding block 4 and the fixing block 5 abut against the inner wall of the first pipe 1 respectively, while the locking block 3 presses down against the outer wall of the second pipe 2. The sliding block 4 and the fixing block 5 abut against the two sides of the locking block 3 respectively, making the locking block 3 more stable.
[0040] The locking block 3, sliding block 4, and fixing block 5 can be made of, but are not limited to, plastic or steel.
[0041] like Figure 4 As shown, since the sliding block 4 and the fixed block 5 abut against the inner wall of the first tube 1, the top of the sliding block 4 and the top of the fixed block 5 are provided with a first structure that abuts against a portion of the inner contour of the first tube 1, thereby maintaining stability when abutting. For example, the first structure can be a plane, an arc surface, a groove, or a triangular ridge, etc., which can be different depending on the inner contour of the first tube 1. Similarly, since the locking block 3 abuts against the outer wall of the second tube 2, the bottom of the locking block 3 is provided with a second structure that abuts against a portion of the outer contour of the second tube 2. The second structure can also be a plane, an arc, a groove, or a triangular ridge, etc.
[0042] like Figure 4 As shown, in some embodiments, the fixed block 5 is provided with a protruding edge 53 on the side opposite to the sliding block 4. The protruding edge 53 can abut against the end of the first tube 1. That is, when the fixed block 5 is placed between the first tube 1 and the second tube 2, the protruding edge 53 abuts against the opening of the first tube 1, thereby restricting the movement of the fixed block 5 relative to the first tube 1 and keeping it at the current opening position of the first tube 1, thus maintaining the stability, aesthetics and ease of adjustment of the connection.
[0043] like Figure 3 and Figure 4As shown, in some embodiments, the locking member 6 can be a bolt, so that the bolt shank directly passes through the first through hole 31 and the second through hole 51 and is screwed into the bolt hole 42, and the bolt head abuts against the side of the fixing block 5 away from the sliding block 4; in the current embodiment, the second through hole 51 is a stepped hole, and the large diameter section of the stepped hole is set at the end of the small diameter section of the stepped hole away from the sliding block 4, so that the bolt head of the expansion bolt can be embedded in the stepped hole, making it more aesthetically pleasing, and also reducing the external force acting on the bolt, reducing the possibility of accidental collision.
[0044] like Figure 5 and Figure 6 As shown, in some alternative embodiments, the locking member 6 is provided with a connecting rod 61 and a cam handle 62. The cam handle 62 is rotatably disposed at the first end of the connecting rod 61, and the second end of the connecting rod 61 is connected to the sliding block 4. For example, the second end of the connecting rod 61 can be welded to the sliding block 4; or the second end of the connecting rod 61 can be inserted into the screw hole 42 and press against the sliding block 4; or the second end of the connecting rod 61 can be threaded so that it can be screwed into the screw hole 42 on the sliding block 4. When the cam handle 62 and the connecting rod 61 are in the same straight line, by rotating the cam handle 62, different parts of the cam at the end of the cam handle 62 abut against the fixing block 5, thereby driving the connecting rod 61 to move relative to the locking block 3, and then pulling the sliding block 4 to move relative to the locking block 3, so that the sliding block 4 and the fixing block 5 respectively abut against the inner wall of the first tube 1, while the locking block 3 presses down against the outer wall of the second tube 2. In the current embodiment, a gasket 63 is also fitted on the connecting rod 61. The gasket 63 is disposed between the cam at the end of the cam handle 62 and the fixing block 5, so that the cam handle 62 abuts against the gasket 63, reducing damage to the fixing block 5.
[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
