Description

Technical Field

[0001] The utility model relates to the field of horizontal bars, in particular to a horizontal bar fixing seat. Background Art

[0002] Chinese patent document CN220237654U discloses an indoor horizontal bar with a more secure installation, including a main body, telescopic rods that can move along the axial direction are inserted at both ends of the main body, and support components are arranged at the ends of the telescopic rods. The support component includes a mounting seat and a sliding seat, and a sloped protrusion is formed on the side where the sliding seat is connected to the mounting seat, and a supporting slope is formed on the mounting seat, and the supporting slope is wedge-shaped with a small top and a large bottom; the support component also includes an anti-slip part, the upper end of the anti-slip part is rotatably connected to the sliding seat through a first rotating shaft, and the middle part of the anti-slip part is rotatably connected to the mounting seat through a second rotating shaft, and an abutment part is formed on one side of the anti-slip part. When the sliding seat moves downward relative to the mounting seat, the anti-slip part is linked to increase the friction force of the abutment part against the wall.

[0003] In the above scheme, the anti-slip part is respectively connected to the first rotating shaft and the second rotating shaft, utilizing the lever principle. However, it can be seen from the drawings in the specification that the first rotating shaft has no movable space, and the anti-slip part cannot be driven to realize the lever principle when the sliding seat moves downward. It is almost impossible to apply force toward the wall to the anti-slip part, and the supporting force of the horizontal bar cannot be enhanced. Utility Model Content

[0004] The utility model aims to provide a horizontal bar fixing seat with firmer support.

[0005] The purpose of the utility model is achieved through the following technologies:

[0006] A horizontal bar fixing seat is arranged at the end of the horizontal bar body and is used to support the horizontal bar body on a mounting surface. The seat comprises a main seat body, a sub-seat body, a connecting rod and a first elastic member. The rear end of the main seat body is connected to the end of the horizontal bar body, the front end of the main seat body is formed with a main fixing surface that can be fitted with the mounting surface, the front end of the sub-seat body is formed with a sub-fixing surface that can be fitted with the mounting surface, one end of the connecting rod is rotatably connected to the main seat body, and the other end is rotatably connected to the sub-seat body. The first elastic member is used to drive the sub-seat body to fit on the mounting surface. When the main seat body is subjected to a downward force, the force can apply a force toward the mounting surface to the sub-seat body through the connecting rod.

[0007] When the user uses the horizontal bar for exercise, the downward force applied will push the main seat body slightly downward or make the main seat body tend to move downward. Through the connecting rod, this force will push the auxiliary seat body toward the installation surface, thereby increasing the supporting force of the auxiliary seat body and making the horizontal bar more stable. If a large weight presses down on the horizontal bar, the main seat body may partially separate from the installation surface as the horizontal bar body is deformed. At this time, since the connecting rod is rotatably connected to the main seat body and the auxiliary seat body, the auxiliary seat body will not separate from the installation surface. Even if the main seat body loses its supporting force, the auxiliary seat body will still press against the installation surface for support, which is safer. The first elastic member can provide a pre-tightening force to the auxiliary seat body during installation so that the auxiliary seat body can remain firmly attached to the installation surface.

[0008] The connection point between the connecting rod and the main seat body is higher than the connection point between the connecting rod and the auxiliary seat body, so that when the main seat body is driven to move slightly downward or has a tendency to move downward, the connecting rod can well apply a force toward the mounting surface to the auxiliary seat body. If the connection point between the connecting rod and the main seat body is lower than the connection point between the connecting rod and the auxiliary seat body, the force driving the main seat body downward may cause it to fall off and fail to achieve the supporting effect.

[0009] When the horizontal bar body is installed and not in use, the angle between the connecting rod and the horizontal line is 10-35 degrees. Setting the angle of the connecting rod in this range can better realize the main seat body applying force toward the installation surface to the auxiliary seat body through the connecting rod. If the angle is less than 10 degrees, the force driving the main seat body downward may cause the connection point between the connecting rod and the main seat body to be lower than the connection point between the connecting rod and the auxiliary seat body, causing the connecting rod to provide an oblique upward force to the auxiliary seat body, reducing the supporting force of the auxiliary seat body, and making it easy to slip; if the angle is greater than 35 degrees, the force applied by the main seat body to the auxiliary seat body toward the installation surface through the connecting rod is too small, resulting in too little supporting force for the auxiliary seat body, making it easy to slip.

[0010] The main seat body includes a fixed support block and a movable support block, the front end of the fixed support block is provided with the main fixed surface, the movable support block can be slidably arranged at the rear end of the fixed support block up and down, the movable support block is connected with the end of the horizontal bar body, the fixed support block is provided with a first inclined surface inclined from top to bottom and backward, the movable support block is provided with a second inclined surface abutting the first inclined surface, the connecting rod is rotatably connected with the movable support block, when the movable support block is subjected to a downward force from the horizontal bar body, since the first inclined surface is inclined from top to bottom and backward, the cooperation of the first inclined surface and the second inclined surface can enable the movable support block to apply a force toward the mounting surface to the fixed support block, so that the supporting force of the fixed support block is stronger, so that the greater the downward force of the horizontal bar, the stronger the supporting force of the fixed support block toward the mounting surface.

[0011] A second elastic member is provided between the fixed support block and the movable support block to drive the movable support block to slide upward. The second elastic member drives the movable support block upward to prevent the movable support block from sliding downward during installation, thereby facilitating the installation of the product.

[0012] The first elastic member is a first compression spring compressed between the movable supporting block and the auxiliary seat body.

[0013] The second elastic member is a second compression spring compressed between the movable support block and the fixed support block.

[0014] The movable support block is movably connected to the fixed support block by screws. The fixed support block is provided with an elongated hole extending up and down. The screw passes through the elongated hole and is locked and connected to the movable support block. The elongated hole can provide space for the screw to move up and down, so that the movable support block can move up and down relative to the fixed support block without being blocked within a certain range.

[0015] The fixed support block is formed with a sliding groove extending up and down, and the movable support block can be movably arranged on the sliding groove up and down, and the sliding groove allows the movable support block to slide smoothly.

[0016] The two connecting rods are arranged in parallel and opposite to each other. The two connecting rods are more reasonable in structure and have higher strength.

[0017] The connecting rod is rotatably connected to the sub-base body through a first pivot shaft. The sub-base body includes a main body and a rear cover. The rear cover is arranged on the main body. An installation groove adapted to the first pivot shaft is arranged between the main body and the rear cover. The rear cover is formed with a clearance gap for the connecting rod to pass through. In this way, during installation, the connecting rod can be connected to the main body first, the first pivot shaft is arranged in the installation groove, and then the rear cover is covered for easy installation.

[0018] The auxiliary fixing surface includes a first block and two second blocks symmetrically arranged on both sides of the first block. Arranging the auxiliary fixing surface into the first block and the second block can increase the contact area between the auxiliary seat body and the installation surface and enhance the supporting force.

[0019] The main seat body is provided with a support part. When the horizontal bar body is bent under force and drives the main seat body to rotate around the connection point between the connecting rod and the main seat body, the support part can be pressed tightly against the rear end of the auxiliary seat body to apply a force toward the installation surface to the auxiliary seat body. In this way, when the main seat body loses supporting force during rotation, a force toward the installation surface can still be applied to the auxiliary seat body, thereby ensuring the supporting force and providing higher safety.

[0032] Reference Figures 1 to 11 As shown, a horizontal bar fixing seat is arranged at the end of the horizontal bar body 4 for supporting the horizontal bar body 4 on the installation surface, including a main seat body 1, a sub-seat body 2, a connecting rod 3, a first elastic member 24 and a second elastic member 14, the main seat body 1 includes a fixed support block 11 and a movable support block 12, the front end of the fixed support block 11 is provided with a first buffer pad 13, the first buffer pad 13 constitutes a main fixed surface A that fits the installation surface, the rear end of the fixed support block 11 is formed with a slide groove 112 for the movable support block 12 to move, the movable support block 12 can be slidably arranged at the rear end of the fixed support block 11, and the rear end of the movable support block 12 is formed with a connecting hole 122, the horizontal bar body The end of 4 is inserted into the connecting hole 122 and connected with the movable support block 12. The fixed support block 11 is provided with a first inclined surface 111 inclined from top to bottom and backward, and the movable support block 12 is provided with a second inclined surface 121 which is in contact with the first inclined surface 111. When the movable support block 12 is subjected to the downward force from the horizontal bar body 4, since the first inclined surface 111 is inclined from top to bottom and backward, the first inclined surface 111 cooperates with the second inclined surface 121 to enable the movable support block 12 to apply a force toward the installation surface to the fixed support block 11, so that the supporting force of the fixed support block 11 is stronger, so that the greater the downward force of the horizontal bar, the stronger the supporting force of the fixed support block 11 toward the installation surface.

[0033] The movable support block 12 is movably connected to the fixed support block 11 through a first screw 114. The fixed support block 11 is provided with an elongated hole 113 extending up and down. The first screw 114 passes through the elongated hole 113 and is locked and connected to the movable support block 12. The elongated hole 113 can provide space for the first screw 114 to move up and down, so that the movable support block 12 can move up and down relative to the fixed support block 11 without being blocked within a certain range. A second elastic member 14 is provided between the fixed support block 11 and the movable support block 12 to drive the movable support block 12 to slide upward. The second elastic member 14 is a second compression spring compressed between the movable support block 12 and the fixed support block 11. The second compression spring drives the movable support block 12 upward to prevent the movable support block 12 from sliding downward during installation, thereby facilitating the installation of the product.

[0034] Symmetrical side holes 123 are formed on both sides of the movable support block 12. One end of the connecting rod 3 is rotatably connected to the movable support block 12 through a second pivot shaft 31 that cooperates with the side hole 123, and the other end is rotatably connected to the sub-base body 2 through a first pivot shaft 32. The second pivot shaft 31 is two bolts inserted into the side holes 123. During installation, the first pivot shaft 32 is first connected to the sub-base body 2, and then the two bolts are passed through the connecting rod 3 and the side holes 123. This makes installation convenient. The first elastic member 24 is a first compression spring compressed between the movable support block 12 and the sub-base body 2. The first compression spring is used to drive the sub-base body 2 to fit onto the mounting surface. When the main base body 1 is subjected to a downward force, the force can apply a force toward the mounting surface to the sub-base body 2 through the connecting rod 3.

[0035] The connection point between the connecting rod 3 and the main seat body 1 is higher than the connection point between the connecting rod 3 and the auxiliary seat body 2. In this way, when the main seat body 1 is driven to move slightly downward or has a tendency to move downward, the connecting rod 3 can well apply a force toward the mounting surface to the auxiliary seat body 2. If the connection point between the connecting rod 3 and the main seat body 1 is lower than the connection point between the connecting rod 3 and the auxiliary seat body 2, the force driving the main seat body 1 downward may cause it to fall off and fail to achieve the supporting effect.

[0036] After the horizontal bar body 4 is installed and not in use, the angle R between the connecting rod 3 and the horizontal line is 10-35 degrees. Setting the angle of the connecting rod 3 in this interval can better realize that the main seat body 1 applies a force toward the installation surface to the auxiliary seat body 2 through the connecting rod 3. If the angle is less than 10 degrees, the force driving the main seat body 1 downward may cause the connection point between the connecting rod 3 and the main seat body 1 to be lower than the connection point between the connecting rod 3 and the auxiliary seat body 2, resulting in the connecting rod 3 providing an oblique upward force to the auxiliary seat body 2, and the supporting force of the auxiliary seat body 2 is reduced, which is easy to slip off; if the angle is greater than 35 degrees, the main seat body 1 applies too little force toward the installation surface to the auxiliary seat body 2 through the connecting rod 3, resulting in too little supporting force of the auxiliary seat body 2, which is easy to slip off. In this embodiment, the angle R is set to 24 degrees, which is a more preferred angle for realizing the utility model. It includes two connecting rods 3 arranged parallel and oppositely at both ends of the movable support block 12. The two connecting rods 3 are more reasonable in structure and have higher strength.

[0037] The sub-base body 2 includes a main body 21 and a rear cover 22. The rear cover 22 is arranged on the main body 21. A mounting groove 213 adapted to the first pivot shaft 32 and a slot 214 for partially inserting the connecting rod 3 are arranged between the main body 21 and the rear cover 22. The rear cover 22 is formed with a clearance notch 221 for the connecting rod 3 to pass through. In this way, when installing, the connecting rod 3 can be first inserted into the main body 21 for connection, the first pivot shaft 32 is placed in the mounting groove 213, and then the rear cover 22 is covered. Finally, the rear cover 22 and the main body 21 are locked by a second screw (not shown in the figure) for easy installation. A spring mounting seat 222 is formed on the rear cover 22. One end of the first elastic member 24 is arranged on the spring mounting seat 222, and the other end is pressed against the movable support block 12 to facilitate the positioning of the first elastic member 24. A second buffer pad 23 is provided at the front end of the main body 21. The second buffer pad 23 constitutes a secondary fixing surface B that fits the mounting surface. The secondary fixing surface B includes a first block B1 and a second block B2 symmetrically arranged on both sides of the first block B1. The arrangement of the first block B1 and the second block B2 can increase the contact area between the secondary seat body 2 and the mounting surface and enhance the supporting force.

[0038] A support portion 25 is formed at the lower front end of the movable support block 12. When the horizontal bar body 4 is subjected to a large force and bends, driving the main seat body 1 to rotate around the connection point between the connecting rod 3 and the main seat body 1, the support portion 25 can be pressed against the rear end of the auxiliary seat body 2 to apply a force toward the installation surface to the auxiliary seat body 2. In this way, when the main seat body 1 rotates and loses the supporting force, a force toward the installation surface can still be applied to the auxiliary seat body 2, thereby ensuring the supporting force and providing higher safety.

[0039] When the user uses the horizontal bar for exercise, the downward force applied to the horizontal bar body 4 will slightly push the movable support block 12 of the main seat body 1 downward or make the movable support block 12 tend to move downward. Through the connecting rod 3, this force will push the auxiliary seat body 2 toward the installation surface, thereby increasing the supporting force of the auxiliary seat body 2 and making the horizontal bar more stable. Fig.10and Fig.11 As shown, if a large weight presses down on the horizontal bar, the movable support block 12 will be pushed downward by the downward force of the horizontal bar body 4, and the fixed support block 11 may be partially separated from the mounting surface. At this time, since the connecting rod 3 is rotatably connected to the main seat body 1 and the auxiliary seat body 2, the auxiliary seat body 2 will not separate from the mounting surface. Even if the main seat body 1 loses its supporting force, the auxiliary seat body 2 will still be pressed against the mounting surface for support, which is safer. The first elastic member 24 can provide a pre-tightening force to the auxiliary seat body 2 during installation, so that the auxiliary seat body 2 can remain firmly attached to the mounting surface.

[0040] Installation process: First, set the second elastic member 14 on the movable support block 12, align the first inclined surface 111 and the second inclined surface 121, align the front end of the movable support block 12 with the slide groove 112, and then pass the first screw 114 through the long hole 113 of the fixed support block 11 to lock the movable support block 12. Secondly, the first pivot shaft 32 passes through the connecting rod 3, and the front end of the connecting rod 3 is inserted into the slot 214 of the auxiliary seat body 2. The first pivot shaft 32 is also inserted into the installation groove 213, and one end of the first elastic member 24 is set on the spring mounting of the rear cover 22 of the auxiliary seat body 2. On the mounting seat 222, the movable support block 12 is connected to the auxiliary seat body 2 and the first elastic member 24 is compressed. The auxiliary seat body 2 will be driven toward the mounting surface by the first elastic member 24. At this time, the other end of the connecting rod 3 is aligned with the two side holes 123 of the movable support block 12, and the second pivot shaft 31 passes through the connecting rod 3 and the two side holes 123. Then, the main body 21 and the rear cover 22 of the auxiliary seat body 2 are locked by the second screw to realize the connection between the main seat body 1 and the auxiliary seat body 2. Finally, the horizontal bar body 4 is inserted into the connecting hole 122 of the movable support block 12 to tighten the horizontal bar fixing seat against the mounting surface.

[0041] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
