Description

Technical Field

[0001] The utility model relates to the technical field of ton barrel auxiliary tools, in particular to a ton barrel valve tightening machine. Background Art

[0002] Ton barrels are containers mainly used for storing or transporting liquid products. Ton barrels are generally composed of containers and metal frames. The container is generally provided with an inlet at the top and a valve at the bottom. In the production process of ton barrels, the container is generally installed with valves after it is placed in the metal frame. The valve installation generally requires the use of tools. Most of the existing tools cannot arbitrarily match the requirements of different types of valves, so in many cases, traditional pipe clamps are required. Therefore, we propose a special tool that can easily adjust the clamping assembly and can be applied to different types of valves to solve the above problems. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing valve screwing tools can only adapt to a limited number of valve models, and the clamping

[0004] The adjustment is inconvenient. Aiming at the above-mentioned defects of the prior art, a ton barrel valve tightening machine is provided.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A ton barrel valve tightening machine is constructed, comprising a mounting seat, a clamping assembly, a control assembly and a return spring. The clamping assembly is movably arranged in the mounting seat. The operator presses the control assembly to control the clamping assembly to open along a preset path so that the clamping assembly can be sleeved on the valve; when the pressure is released, the clamping assembly closes or approaches along the preset path under the action of the return spring so that the clamping assembly clamps the valve.

[0007] Preferably, the mounting seat is a square box body which is hollow and open at both ends, a handle is fixedly provided on the top of a pair of opposite side walls of the box body, and a first guide hole and a second guide hole are opened on the pair of opposite side walls, and a third guide hole is opened on the other pair of opposite side walls of the box body; wherein the third guide hole is a circular through hole, and the first guide hole and the second guide hole are both strip-shaped through holes; the handle is a gantry structure, and a fourth guide column is provided on the top of the handle.

[0008] Preferably, the clamping assembly comprises two clamping terminals arranged facing each other, the clamping terminal having an arc-shaped clamping surface, a first guide column is provided on the side of the clamping terminal opposite to the clamping surface, and second guide columns are provided on both side surfaces adjacent to the clamping surface.

[0009] Preferably, the first guiding post of the clamping assembly is movably arranged in the third guiding hole, and the second guiding post is movably arranged in the second guiding hole; when the clamping assembly moves along a preset path, the first guiding post slides along the axial direction of the third guiding hole, and the second guiding post slides along the length direction of the second guiding hole.

[0010] Preferably, a plurality of anti-slip protrusions are arranged on the clamping surface. When turning the valve, the anti-slip protrusions hold the valve to prevent relative rotation between the valve and the clamping surface.

[0011] Preferably, the control assembly includes a control handle and a connecting rod. The control handle has a "冂"-shaped structure and is arranged closely on both sides of the handle. The fourth guiding post on the handle passes through the through hole on the control handle. The lower end of each side of the control handle is hinged to the upper end of a connecting rod arranged inside the base through a pin shaft. The pin shaft passes through the first guiding hole and can slide along the length direction of the first guiding hole in the first guiding hole. The lower ends of the two connecting rods on the same side of the control handle are respectively hinged to the second guiding posts on the two clamping terminals, and the included angle between the two connecting rods faces downward of the base.

[0012] Preferably, the return spring includes a first return spring and a second return spring. The first return spring is sleeved on the first guiding post. One end of the first return spring presses against the inner side wall of the mounting seat, and the other end presses against the clamping terminal. The elastic force of the first return spring makes the two clamping terminals keep a moving trend of approaching each other; the second return spring is sleeved on the fourth guiding post. One end of the fourth return spring presses against the upper side of the top of the handle, and the other end presses against the lower side of the top of the control handle. The elastic force of the second return spring makes the control handle keep an upward moving trend. The upward movement of the control handle pulls the included angle between the two connecting rods on the same side to become smaller, thereby making the two clamping terminals keep a moving trend of approaching each other.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The two clamping terminals in the present utility model always keep a moving trend of approaching each other under the action of the return spring. Therefore, when using the device to turn the valve, the clamping terminals can automatically clamp the valve after being sleeved on the valve.

[0015] 2. The control assembly and the clamping assembly in the present utility model can be linked, so that the opening and closing of the clamping assembly can be directly controlled through the control assembly, and the operation is simple.

[0016] 3. The clamping terminal of the utility model can maintain a tendency to move toward each other under the action of the first return spring to clamp the invention located therein; and the unpressed control handle moves upward under the action of the second return spring, so that the control handle pulls the connecting rod and the pin shaft to slide upward along the third guide hole, and then the second guide column is pulled by the connecting rod to move in the second guide hole toward the side close to the third guide hole, that is, the control handle can play an auxiliary role in the clamping state of the clamping terminal;

[0017] 4. When in use, the operator only needs to press the top of the control handle to force the control handle to move downward to automatically open the two clamping terminals, and then the valve can be easily placed between the two clamping terminals. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0026] In order to facilitate the description of the connection relationship between the various components, the handle is defined to be located above the mounting base, and other positions are deduced based on this, as follows: Figure 1 The side of the middle mounting seat where the handle is provided is the upper side, and the opposite side is the lower side.

[0027] like Figure 1-Figure 6 A preferred embodiment of the utility model is provided, a ton barrel valve tightening machine, comprising a mounting seat 100, a clamping assembly 200, a control assembly 300 and a reset spring, wherein the mounting seat 100 is used as a bearing part for setting the clamping assembly 200 and the control assembly 300, the clamping assembly 200 is used to clamp the valve, and when the mounting seat 100 is rotated, the clamping assembly 200 can be driven to tighten the valve, and the control assembly 300 is used to control the clamping assembly 200 to open so that the clamping assembly 200 can be mounted on the valve.

[0028] Among them, the clamping component 200 is movably arranged in the mounting seat 100, the clamping component 200 can slide on a plane parallel to the two end surfaces of the mounting seat 100, and the control component 300 can move up and down in the vertical direction. The operator presses the control component 300 to make the control component 300 move downward, and then controls the clamping component 200 to open along a preset path, so that the clamping component 200 can be mounted on the valve; release the pressure, and the clamping component 200 closes or approaches along the preset path under the action of the return spring (401, 402), so that the clamping component clamps the valve.

[0029] like Figure 1-4 As shown, the mounting seat 100 is a hollow square box body, the upper end and the lower end of the square box body are open so that the square box body is a cylindrical tube with two ends open, a handle 101 is fixedly arranged on the top of a pair of opposite side walls of the box body, and a first guide hole 102 and a second guide hole 103 are opened on the pair of side walls, and a third guide hole 104 is opened on the other pair of opposite side walls of the box body; wherein the third guide hole 104 is a circular through hole, and the first guide hole 102 and the second guide hole 103 are both strip-shaped through holes; the handle 101 is a gantry structure, and a fourth guide column 105 is provided on the top of the handle 101.

[0030] Furthermore, the top of the handle 101 extends toward both sides to form a holding end 1011, and two through holes are opened in the vertical parts of the holding end near both sides of the handle. When turning the valve, the operator can hold the holding end 1011 to rotate the mounting seat, thereby driving the clamping assembly 200 to turn the valve.

[0031] In some embodiments, the clamping assembly 200 includes two clamping terminals 201 arranged opposite to each other. Each clamping terminal 201 has an arc-shaped clamping surface 201a. The valve area is located between the two opposite clamping surfaces. A first guiding post 2011 is provided on the side of the clamping terminal 201 opposite to the clamping surface 201a, and second guiding posts 2012 are provided on the two sides adjacent to the clamping surface 201a. A limiting disk is formed at the end of the first guiding post 2011. The limiting disk can ensure that when the clamping terminal 201 moves along a preset path in the mounting seat 100, the first guiding post 2011 will not disengage from the third guiding hole 104.

[0032] The specific connection relationships between the guiding posts and guiding holes in the foregoing embodiments are as follows: The first guiding post 2011 is movably arranged in the third guiding hole 104, and the second guiding post 2012 is movably arranged in the second guiding hole 103; when the clamping assembly 200 moves along a preset path, the first guiding post 2011 slides along the axial direction of the third guiding hole 104, and the second guiding post 2012 slides along the length direction of the second guiding hole 103.

[0033] To ensure that when the clamping assembly clamps and turns the valve, the valve and the clamping surface 201a will not rotate relative to each other, a number of anti-slip protrusions 201a1 are provided on the clamping surface 201a. When turning the valve, the anti-slip protrusions 201a1 catch the valve, thereby preventing the valve from rotating relative to the clamping surface 201a.

[0034] In this embodiment, the control assembly 300 includes a control handle 301 and a connecting rod 302. The control handle 301 has a "冂"-shaped structure. The two sides of the control handle 301 pass through the through holes on the holding end and are arranged closely against the two sides of the handle 101. The lower ends of the two sides of the control handle 301 extend to the first guiding hole 102. The fourth guiding post 105 on the handle 101 passes through the through hole on the control handle 301. The lower end of each side of the control handle 301 is hinged to the upper end of a connecting rod 302 arranged inside the base through a pin shaft 303. The pin shaft 303 passes through the first guiding hole 102 (here, the pin shaft also has a guiding function, that is, the pin shaft can be used as the third guiding post), and the pin shaft 303 can slide along the length direction of the first guiding hole 102 in the first guiding hole 102. The lower ends of the two connecting rods 302 on the same side of the control handle 301 are respectively hinged to the second guiding posts 2012 on the two clamping terminals 201, and the included angle between the two connecting rods 302 faces downward of the mounting seat. In this way, when the control handle 301 moves downward, the pin shaft 302 slides downward in the first guiding hole 102, and the second guiding posts 2012 on the two clamping terminals 201 move away from each other in the corresponding second guiding holes 103, and the included angle between the two connecting rods 302 becomes larger; conversely, the included angle between the two connecting rods 302 becomes smaller.

[0035] It should be noted that the aforementioned return spring includes a first return spring 401 and a second return spring 402, wherein the first return spring 401 is sleeved on the first guide column 2011, and one end of the first return spring 401 is pressed against the inner wall of the mounting seat 100, and the other end is pressed against the clamping terminal 201, and the elastic force of the first return spring 401 makes the two clamping terminals 201 maintain a movement trend towards each other; the second return spring 402 is sleeved on the fourth guide column 105, and one end of the fourth return spring 402 is pressed against the upper side of the top of the handle 101, and the other end is pressed against the lower side of the top of the control handle 301, and the elastic force of the second return spring 402 makes the control handle maintain an upward movement trend, and the upward movement of the control handle 301 pulls the angle between the two connecting rods 302 on the same side to become smaller, thereby making the two clamping terminals 201 maintain a movement trend towards each other, thereby clamping the valve between the two clamping terminals 201.
