AI Technical Summary
The existing screw-buckle type tube clamps have certain elasticity during use, which can easily lead to loosening of the thread fit and affect the stability of the clamping.
A screw-button type tube clamp including a fixing frame, a movable frame, a threaded tube, a screw rod, a knob, a blocking mechanism, a limit seat, a connecting rod, a handle and a spring are designed. Through the coordination of the limit seat, connecting rod and handle, the spring force of the spring limits the knob and screw to avoid loosening of the thread. At the same time, the structure of the baffle, limit frame and reset frame is further prevented from loosening caused by sliding of the knob.
It effectively avoids loosening of thread fit, improves the clamping stability of the pipe clamp, and ensures a firm connection between the knob and the screw during use.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screw-type pipe clamps, and particularly relates to a screw-type pipe clamp that is not easy to loosen. Background Technique
[0002] The pipe clamp is sleeved from the bottom of the test tube and clamped at one-third or the upper-middle part of the test tube mouth. After clamping, immediately place the hand on the long handle, and the thumb should not press on the short handle. When removing, also remove it from the lower end and never touch the tube mouth. When heating the test tube, it is necessary to continuously oscillate the test tube to make the heating uniform. In order to improve the clamping force on the test tube, the test tube can be clamped by means of a threaded fit. However, the screw-type pipe clamp in the prior art has a certain elasticity during use, which easily causes the threaded fit to become loose and affects the clamping stability. Therefore, the prior art needs to be improved. Content of the Utility Model

[0004] To achieve the above purpose, the utility model provides the following technical solution: a screw-type pipe clamp that is not easy to loosen, including a fixed frame, an activity frame is hinged inside the fixed frame, a threaded pipe is hinged inside the activity frame, a screw rod is connected inside the threaded pipe through a thread, a knob is fixedly connected to the outer side of the screw rod, a blocking mechanism is arranged on the fixed frame, a toothed ring is fixedly connected to the upper end of the knob, a limit seat is slidably connected inside the fixed frame, a connecting rod is fixedly connected to the outer side of the limit seat, a pull handle is fixedly connected to one end of the connecting rod located outside the fixed frame, and a first spring is arranged on the outer side of the connecting rod.
[0005] Preferably, the connecting rod is slidably connected to the fixed frame, the pull handle contacts the fixed frame, and the pull handle can drive the connecting rod to move.
[0006] Preferably, the toothed ring is movably connected to the fixed frame, the limit seat is clamped with the toothed ring, and the limit seat can limit the knob through the toothed ring.
[0007] Preferably, one end of the first spring is fixedly connected to the limit seat, and the other end of the first spring is fixedly connected to the fixed frame. The first spring can drive the limit seat to automatically reset through the elastic force.
[0008] Preferably, the blocking mechanism includes a baffle plate, the baffle plate is hinged to the outer side of the fixed frame, a limit frame contacts the outer side of the fixed frame, a reset frame is slidably connected inside the fixed frame, a second spring is arranged on the outer side of the rod member of the reset frame, and the reset frame is fixedly connected to the limit frame.

The limiting frame is slidably connected to the baffle. The second spring can drive the reset frame to automatically reset through its elastic force.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] 1. By adding structures such as a limiting seat, a connecting rod, and a handle to the fixed frame, after the knob and the screw are tightened, the elastic force of the first spring can drive the limiting seat to slide into the interior of the toothed ring to limit the knob and the screw. Therefore, during the use of the pipe clamp, the toothed ring can be limited by the limiting seat, effectively preventing the loosening of the thread fit.
[0012] 2. By adding structures such as a baffle, a limiting frame, and a reset frame to the fixed frame, after the pipe clamp is clamped, the baffle can be flipped to the inner side of the limiting frame to limit the screw, thereby preventing the knob from being blocked when the knob slides, and further preventing the pipe clamp from loosening.
