[0030] The utility model will be described in further detail below in combination with the drawings.

[0031] Referring to Figure 1 and 3 The counterweight column is generally applicable to furniture, such as tables, stools or telescopic tables and the like, and the counterweight column mainly serves to support the corresponding carrier. Taking a table as an example, the carrier is a table top, and the counterweight column is arranged at the lower end of the table top to support the table top. The counterweight column comprises a stand column 100, the stand column 100 is internally provided with a counterweight cavity, the counterweight cavity is provided with an opening at the upper end of the stand column 100, and a counterweight piece is detachably arranged in the counterweight cavity. The counterweight piece is assembled in the counterweight cavity through the opening. The counterweight piece comprises a counterweight tube 200, an end cap 300, an inner tube 400 and a screw rod 600. The inner tube 400 is arranged inside the counterweight tube 200, and the screw rod 600 is arranged inside the inner tube 400. The axes of the screw rod 600, the inner tube 400 and the counterweight column coincide. One end of the screw rod 600 is connected to the end cap 300, and the other end is connected to the bottom of the counterweight cavity. In this way, the counterweight tube 200 can be limited in the counterweight cavity through the connecting action of the screw rod 600.

[0032] In the embodiment, the end cap 300 is arranged at the upper end of the counterweight column or arranged at both ends. The end cap 300 is provided with an opening 311, and one end of the inner tube 400 can be mounted in the opening 311 of the inner tube 400. The two can be screwed or inserted. The end cap 300 comprises a cover body 310 and an extension foot 320. The outer periphery of the cover body 310 is adapted to the inner wall of the counterweight cavity, and the two can be arranged in interference fit, clearance fit or overfit. The extension foot 320 is inserted against the end of the configuration tube. In this way, the counterweight tube 200 can be stably and tightly limited in the counterweight cavity by the arrangement of the end cap 300, so as to realize the pre-connection of the counterweight tube 200 in the counterweight cavity, thereby facilitating the subsequent fastening and locking after the screw rod 600 is penetrated.

[0033] In the embodiment, the bottom of the counterweight cavity is provided with a bottom plate 500 (the bottom plate 500 is arranged at the end of the stand column 100 away from the opening), a through hole 510 is arranged at the center position of the bottom plate 500, the lower end of the screw rod 600 can be screwed in the through hole 510, or the lower end of the screw rod 600 is connected with the bottom plate 500 after being fastened with the screw rod 600 through a nut, and the upper end of the screw rod 600 is screwed on the end cover 300. Thus, the upper and lower ends of the counterweight pipe 200 are fixed, so that the counterweight pipe 200 is limited in the counterweight cavity.

[0034] Based on the above embodiment, the counterweight pipe 200, the inner pipe 400 and the end cover 300 can be integrally formed, the counterweight pipe 200 can be poured with cement, and then the three are integrally connected, and after the three are integrally formed, the opening is inserted into the inside of the counterweight cavity, and then the screw rod 600 is locked with the bottom plate 500 and the end cover 300 respectively, so that the whole counterweight part is limited in the stand column 100.

[0035] Based on the above embodiment, the counterweight pipe 200, the inner pipe 400 and the end cover 300 can also be connected in a split manner. Specifically, the end of the counterweight pipe 200 corresponds to the position of the extension leg 320 to set an avoiding slot, so that when the counterweight pipe 200 is connected with the end cover 300, the counterweight pipe 200 can be inserted and combined between the avoiding slot and the end cover 300.

[0036] The shape of the avoiding slot is matched with the shape of the extension leg 320. In the embodiment, the cross section of the extension leg 320 is taken as an example of a rectangular structure, and the avoiding slot is a rectangular slot arranged on the inner wall or the outer wall of the counterweight pipe 200. When the rectangular slot is arranged on the inner wall of the counterweight pipe 200, the outer wall of the inner pipe 400 abuts against the inner wall of the extension leg 320 when the end cover 300 is inserted and combined between the extension leg 320 and the extension slot, and the inner wall of the extension leg 320 abuts against the inner wall of the avoiding slot (as shown in FIG. 8). Figure 1

[0037] When the avoiding slot is arranged on the outer wall of the counterweight pipe 200, the extension leg 320 is arranged between the outer wall of the counterweight pipe 200 and the inner wall of the counterweight cavity when the end cover 300 is combined with the counterweight pipe 200.

[0038] Through the detachable connection of the above three parts, when any part is damaged, the corresponding part can be conveniently replaced, and the maintenance cost of the product is effectively reduced.

[0039] ​Based on the above embodiment, the counterweight pipe 200 is a whole pipe, the length of which is similar to the height of the counterweight cavity, in order to conveniently adjust the weight of the counterweight column according to the configuration needs of different products, the counterweight pipe 200 can also be set as multiple, that is, multiple counterweight pipes 200 are stacked and set in the counterweight cavity, so that when the furniture is a stool or other product without too large counterweight, the number of counterweight columns can be changed to conveniently adjust the weight of the whole counterweight column, and when the furniture is a table or other product that needs to increase the counterweight, the number of counterweight columns can be increased to conveniently complete the product counterweight needs, so that the counterweight column is set as multiple, and multiple counterweight columns are stacked in the counterweight cavity to meet the counterweight needs of different products, thereby increasing the practicality and diversity of the actual use of the counterweight column.

[0040] Based on the above embodiment, the counterweight column can be a cement solid, or a metal piece, such as cast iron, carbon steel alloy or other materials with a certain weight.

[0041] Although the preferred embodiments of the present application have been described in detail above, it should be understood that various modifications and changes can be made by those skilled in the art without departing from the spirit and principles of the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
