Problems solved by technology

[0002] At present, the bases that cooperate with U-shaped tubes generally only have a U-shaped groove that is matched with the U-shaped tube on the base, but because the bottom of the tube is only placed in the U-shaped groove, the tube cannot be clamped, and the tube is very It is easy to change the length, so that the pipe fittings are out of the U-shaped groove, and the use effect is not good

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0023] A U-shaped tube locking device, such as figure 1 , 7 As shown in 8, it is set on a tube expander and includes a base 1. The head of the base 1 is provided with a U-shaped groove 2 that is matched with the U-shaped tube 8, and the base 1 is provided with a clamp for placing The clamping device 3 of the pipe fitting in the U-shaped groove 2 and matched with the pipe fitting can put the bottom of the U-shaped pipe 8 in the U-shaped groove 2, and the clamping device 3 can clamp the bottom of the U-shaped pipe 8.

[0024] Such as figure 2 , 3 As shown in 6, the clamping device 3 includes a positioning shaft 36 arranged on the base 1, and two symmetrical left and right clamping blocks 31, 32 are hinged on the positioning shaft 36. The heads of the right clamping blocks 31 and 32 are respectively provided with grooves 33 that cooperate with the U-shap...

Abstract

The invention relates to a U-type pipe locking device. The locking device comprises a pedestal, wherein the head of the pedestal is provided with a U-type groove matched with the U-type pipe. The locking device is characterized in that the inside of the pedestal is provided with a clamping device which is capable of clamping a pipe piece placed inside the U-type groove and meshed with the pipe piece; the clamping device comprises a positioning shaft arranged on the pedestal; the positioning shaft is hinged with a left clamping block and a right clamping block which are symmetrical; the heads of the left clamping block and the right clamping block are respectively provided with a groove matched with the U-type pipe; and the tail ends of the left clamping block and the right clamping block are provided with push rod components capable of driving both clamping blocks to open and close. The invention aims to provide the U-type pipe locking device which has simple structure and can conveniently clamp a pipe piece placed inside the U-type groove.

Description

【Technical Field】 [0001] The invention relates to a U-shaped tube locking device, in particular to a U-shaped tube locking device used in a tube expander. 【Background technique】 [0002] At present, the bases matched with U-shaped pipes generally only have a U-shaped groove on the base that matches the U-shaped pipe. However, because the bottom of the pipe is only placed in the U-shaped groove, the pipe cannot be clamped, and the pipe is very It is easy to change the length, make the pipe fitting out of the U-shaped groove, and the use effect is not good. [Content of the invention] [0003] The present invention overcomes the shortcomings of the prior art and provides a U-shaped tube locking device which has a simple structure and is very convenient to clamp and place the tube in the U-shaped groove. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: [0005] A U-shaped tube locking device includes a bas...
