Abstract
A device for lengthening a support leg comprises a connecting sleeve and a lengthening rod. A connector on the upper portion of the connecting sleeve is a conical surface, three cut grooves are evenly arranged on the circumference of the conical surface, and a guiding piece which has the same conical degree with the conical surface is mounted in each cut groove. A connector on the lower portion of the connecting sleeve is provided with inner threads and is connected with the lengthening rod with outer threads, and a rubber pad is pasted at the bottom of the lengthening rod. According to the device for lengthening the support leg, the connecting sleeve is connected on the support leg of a table in a sleeved mode, and the guiding pieces in the cut grooves are used for fixing the support leg; the lower portion of the connecting sleeve is connected with the lengthening rod, and therefore the support leg of the table is lengthened. Due to the fact that the connecting sleeve is connected with the lengthening rod through the threads, the length of the lengthened support leg of the table can be adjusted slightly.
Description
Technical field
The present invention relates to the auxiliary lengthening fixed structure of a kind of pin.
Background technology
The table pin of existing dining table, desk just can not be regulated later in formed product, in work and life, sometimes need the height of desk is regulated, this has just brought very large problem to the user, in general the table pin can not stretch again, and generally also there is no need to add the structure of stretching in the process of design.
Summary of the invention
Based on the problems referred to above, the invention provides a kind of device that can the assistant table pin lengthens.
The objective of the invention is to be achieved through the following technical solutions:
A kind of leg length extension device comprises branch sleeve and extension bar, and the upper interface of described branch sleeve is made as the conical surface, and evenly is provided with three groovings on the circumference of the conical surface, and the prerotation vane that equates with the tapering of the conical surface is installed in the described grooving; The bottom interface of described branch sleeve has internal thread, the bottom interface with have externally threaded extension bar and be connected, be bonded with a rubber blanket in the bottom of described extension bar.
The present invention is socketed on the pin by branch sleeve, and is fixed by the prerotation vane in the grooving; The lengthening to the table pin is realized by being connected with extension bar in the bottom of branch sleeve.Be threaded owing to adopts between branch sleeve and the extension bar, can finely tune the length after the lengthening of table pin like this.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the structure chart of the described leg length extension device of the embodiment of the invention.
The specific embodiment
As shown in Figure 1, the described leg length extension device of the embodiment of the invention comprises branch sleeve 1 and extension bar 2, and the upper interface of described branch sleeve 1 is made as the conical surface 3, and on the circumference of the conical surface 3, evenly be provided with three groovings 4, the prerotation vane 5 that equates with the tapering of the conical surface 3 is installed in the described grooving 4; The bottom interface of described branch sleeve 1 has internal thread, the bottom interface with have externally threaded extension bar 2 and be connected, be bonded with a rubber blanket 6 in the bottom of described extension bar 2.
The present invention is socketed on the pin 7 by branch sleeve, and is fixed by the prerotation vane in the grooving; The lengthening to the table pin is realized by being connected with extension bar in the bottom of branch sleeve.Be threaded owing to adopts between branch sleeve and the extension bar, can finely tune the length after the lengthening of table pin like this.
