Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fitness equipment, in particular to a column locking structure of fitness equipment. Background Art
[0002] Fitness equipment is a device or equipment used for physical exercise. It can help people perform various forms of exercise such as strength training, aerobic exercise, and flexibility training. The columns of fitness equipment in the prior art are usually made of a single steel pipe, and are often fixed directly with screws. When they need to be adjusted or disassembled, it is troublesome and inconvenient to use.
[0003] For example, in the prior art, patent publication number CN220151676U discloses a column locking structure for fitness equipment. Compared with the traditional bolt fixing method, this device has the advantages of easy disassembly and assembly, and is adjustable, which effectively facilitates the use of different groups of people and makes it more applicable. By providing a rectangular groove, it enables the connection of multiple round tubes during use, ensuring that horizontal connection can be made during use, effectively improving its use effect.
[0004] However, when the device locks the locking structure on the column, the rotating tube is rotated, and the rotating tube causes the threaded tube to deform so that the threaded tube is clamped on the column for locking. After multiple locking and adjustment, this locking method is likely to cause permanent and non-resilient deformation of the threaded tube. As a result, after the rotating tube is loosened, the threaded tube cannot rebound to its original state, affecting the disassembly and adjustment of the locking structure. Therefore, a column locking structure of fitness equipment is designed to solve the above problem. Utility Model Content
[0005] The purpose of the present utility model is to solve the problems existing in the above-mentioned background technology and to propose a column locking structure for fitness equipment.
[0006] The technical problem to be solved by the present invention is to provide a column locking structure for fitness equipment, which solves the problem in the prior art that the threaded tube of the column locking structure undergoes permanent and non-rebound deformation after repeated use, affecting the subsequent disassembly and adjustment of the locking structure.
[0007] The utility model provides a column locking structure of fitness equipment, comprising a column, a locking assembly and a crossbar, wherein the locking assembly is installed on the column, and the outer surface of the locking assembly is fixedly provided with a crossbar;
[0008] The locking assembly includes a fixed block, an externally threaded through-tube, an internally threaded ring, and a clamping block. An externally threaded through-tube is provided through the bottom of the fixed block, an internally threaded ring is threadedly connected to the externally threaded through-tube, a plurality of through-grooves are provided on the externally threaded through-tube, and a clamping block is embedded in the through-grooves.
[0009] Preferably, the inner diameter of the externally threaded through-tube is equal to the outer diameter of the column, and the externally threaded through-tube is sleeved on the column.
[0010] Preferably, the width and height of the clamping block are respectively the same as the height and width of the through slot.
[0011] Preferably, the inner surface of the clamping block matches the inner surface of the externally threaded through-tube, and the upper outer surface of the clamping block matches the outer surface of the externally threaded through-tube, and the lower outer surface of the clamping block is inclined with the thickness component increasing from top to bottom.
[0012] Preferably, the outer surface of the internal thread ring is provided with an anti-slip strip, and the inner surface of the clamping block is provided with a frosted layer.
[0013] Preferably, a blocking rod is fixedly provided on the upper inner side of the through slot, and a groove is provided above the inner surface of the clamping block.
[0014] Preferably, when the upper side of the outer surface of the clamping block coincides with the outer side surface of the externally threaded through-tube, there is a gap between the upper side of the clamping block and the blocking rod.
[0015] Preferably, when the top of the internal thread ring is attached to the top of the fixing block, the horizontal height of the bottom of the internal thread ring is lower than the horizontal height of the top of the clamping block.
[0016] Compared with the prior art, the present invention has at least the following beneficial effects:
[0017] 1. The utility model is provided with a locking assembly. When the locking assembly is locked on the column, the external threaded through-tube is sleeved on the column, and the external threaded through-tube moves up and down along the column. When the external threaded through-tube is in the position where locking is required, the internal threaded ring is screwed downward until the inner side of the internal threaded ring contacts the inclined surface below the outer surface of the clamping block. The internal threaded ring squeezes the clamping block, so that multiple clamping blocks move toward the column at the same time. The inner surface of the clamping block is tightly attached to the outer surface of the column, thereby achieving the effect of locking the locking assembly on the column.
[0018] 2. The utility model is provided with a groove and a blocking rod, which can prevent the clamping block from passing through the inner side of the through-groove, and the bottom horizontal height of the internal threaded ring is lower than the bottom horizontal height of the clamping block, which can limit the clamping block from escaping from the outside of the through-groove, and prevent the clamping device from escaping from the through-groove when being taken out of the column. When the upper side of the outer surface of the clamping block coincides with the outer side surface of the external threaded through-tube, there is a gap between the upper side of the clamping block and the blocking rod, so that when the internal threaded ring squeezes the clamping block toward the inner side of the through-groove, the blocking rod will not affect the movement of the clamping block, thereby ensuring the clamping and positioning effect of the clamping block on the column.

[0026] Example:
[0027] like Figures 1-4 As shown, an embodiment of the present invention provides a column locking structure for fitness equipment, comprising a column 1, a locking assembly and a crossbar 3. The locking assembly is mounted on the column 1, and the crossbar 3 is fixedly provided on the outer surface of the locking assembly.
[0028] The locking assembly includes a fixed block 2, an externally threaded through-tube 201, an internally threaded ring 202, and a clamping block 203. The bottom of the fixed block 2 is penetrated by an externally threaded through-tube 201, and the internally threaded ring 202 is threadedly connected to the externally threaded through-tube 201. A plurality of through grooves 2011 are provided on the externally threaded through-tube 201, and the clamping block 203 is embedded in the through grooves 2011.
[0029] In this embodiment, the inner diameter of the externally threaded through-tube 201 is equal to the outer diameter of the column 1 , and the externally threaded through-tube 201 is sleeved on the column 1 .
[0030] In this embodiment, the width and height of the clamping block 203 are respectively the same as the height and width of the through-groove 2011 , thereby ensuring that the clamping block is stably located in the through-groove 2011 .
[0031] In this embodiment, the inner surface of the clamping block 203 matches the inner surface of the externally threaded through-tube 201, and the upper portion of the outer surface of the clamping block 203 matches the outer surface of the externally threaded through-tube 201. The lower portion of the outer surface of the clamping block 203 is inclined with the thickness component increasing from top to bottom, which facilitates the internally threaded ring 202 to squeeze the clamping block 203, so that the clamping block 203 clamps the column.
[0032] In this embodiment, the outer surface of the internal thread ring 202 is provided with an anti-slip strip to facilitate the rotation of the internal thread ring 202, and the inner surface of the clamping block 203 is provided with a frosted layer to increase the friction coefficient of the clamping block 203 and increase the friction force after clamping.
[0033] By providing a locking assembly, when the locking assembly is locked on the column 1, the external threaded through-tube 201 is sleeved on the column 1, and the external threaded through-tube 201 moves up and down along the column. When the external threaded through-tube 201 is in the position where it needs to be locked, the internal threaded ring 202 is screwed downward until the inner side of the internal threaded ring 202 contacts the inclined surface below the outer surface of the clamping block 203. The internal threaded ring 202 squeezes the clamping block 203, so that multiple clamping blocks 203 move toward the column 1 at the same time, and the inner surface of the clamping block 203 is tightly attached to the outer surface of the column 1, thereby achieving the effect of locking the locking assembly on the column 1.
[0034] In this embodiment, a blocking rod 2012 is fixedly provided on the upper inner side of the through-slot 2011 , and a groove 2031 is formed on the upper inner surface of the clamping block 203 .
[0035] In this embodiment, when the upper side of the outer surface of the clamping block 203 coincides with the outer side surface of the externally threaded through-tube 201, there is a gap between the upper side of the clamping block 203 and the blocking rod 2012, so that when the internally threaded ring 202 squeezes the clamping block 203 toward the inner side of the through-groove 2011, the blocking rod 2012 will not affect the movement of the clamping block 203.
[0036] In this embodiment, when the top of the internal threaded ring 202 is attached to the top of the fixed block 2, the bottom level of the internal threaded ring 202 is lower than the top level of the clamping block 203. The internal threaded ring 202 can limit the clamping block 203 from escaping from the outside of the through groove 2011.
[0037] By providing the groove 2031 and the blocking rod 2012, the blocking rod 2012 can prevent the clamping block 203 from passing through the inner side of the through groove 2011, and the bottom horizontal height of the internal threaded ring 202 is lower than the bottom horizontal height of the clamping block 203, which can limit the clamping block 203 from escaping from the outside of the through groove 2011, preventing the clamping device from escaping from the through groove 2011 when being taken out of the column 1. When the upper side surface of the clamping block 203 coincides with the outer side surface of the externally threaded through tube 201, there is a gap between the upper side of the clamping block 203 and the blocking rod 2012, so that when the internal threaded ring 202 squeezes the clamping block 203 toward the inner side of the through groove 2011, the blocking rod 2012 will not affect the movement of the clamping block 203, thereby ensuring the clamping and positioning effect of the clamping block 203 on the column 1.
[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
