Description

Technical Field

[0001] The utility model is applicable to the field of extruders and provides a manual extruder. Background Art

[0002] Manual dispensing is a manually operated process used to apply glue at specific locations during product assembly. It is commonly used in product manufacturing in the electronics, automotive, aerospace and other industries for fixing, sealing or insulation.

[0003] Manual dispensing requires attention to the viscosity of the glue, the accuracy of the dispensing position, and the control of the dispensing pressure and speed to ensure that the glue can be effectively fixed in the designated position and achieve the desired effect.

[0004] Currently, the tool used for manual dispensing is a small glue cylinder and a push rod. People use their fingers to press the push rod to squeeze out the glue. This method of dispensing is not easy to operate and lacks precision. It is difficult for unskilled workers to control the dispensing pressure and speed, making it difficult to use. Utility Model Content

[0005] In view of the above-mentioned defects, the purpose of the utility model is to provide a manual extruder, the purpose is to solve the problems raised in the background technology, the device includes a fixed sleeve, a hinged portion is installed on one side of the fixed sleeve, a handle is hinged on the hinged portion, a through hole is provided on the handle, a rod body is sleeved in the through hole, a pipe plug is installed at the bottom of the rod body, and a ratchet is provided on one side of the rod body.

[0006] The handle is provided with a pin shaft groove, and the handle is provided with a spring groove connected to the pin shaft groove. A pin shaft and a spring are respectively installed in the pin shaft groove and the spring groove. The spring abuts against the pin shaft, and the pin shaft cooperates with the ratchet.

[0007] Furthermore, the rod body is fixedly connected to the pipe plug via a pipe plug seat.

[0008] Furthermore, a pipe plug wide card is installed on the pipe plug seat.

[0009] Furthermore, two of the pipe plug wide clamps are provided on the pipe plug seat.

[0010] Furthermore, a torsion spring is installed on the pipe plug seat, and two ends of the torsion spring are provided with bent parts.

[0011] Furthermore, a curved surface is provided on a surface of the through hole away from the ratchet teeth.

[0012] Furthermore, a handle is installed on the top of the rod body.

[0013] Furthermore, a pin shaft dial button is provided on the pin shaft.

[0014] In summary, in actual use, the user needs to first open the handle around the hinge, put the material tube into the fixed sleeve, and then close the handle. At this time, the tube plug at the bottom of the rod body will be inserted into the material tube. On the one hand, the user can press the handle on the top of the rod body to push the material in the material tube out; on the other hand, the user can turn the handle to rotate, and the pin shaft in the handle cooperates with the ratchet so that the rod body can only move downward relative to the handle. The pin shaft climbs up along the rod body over several teeth, and then resets under the action of the torsion spring. Then squeeze the handle, and the handle drives the rod body to move downward under the cooperation of the pin shaft and the ratchet. As the handle is squeezed, the material can be squeezed out continuously and evenly by the user.

[0015] Therefore, the extruder can achieve continuous and uniform extrusion and precise glue dispensing; since the ratchet teeth are uniform, quantitative extrusion can be achieved according to the number of teeth, and unskilled workers can also easily control the glue dispensing pressure and speed. The device is easy to operate and suitable for large-scale use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] See also Figure 1-7 The purpose of the utility model is to provide a manual extruder, including a fixed sleeve 1, the fixed sleeve 1 has upper and lower openings, a material tube 01 can be inserted into the fixed sleeve 1 from the top of the fixed sleeve 1, and the top and bottom of the material tube 01 are respectively provided with a limit ring 011 and a discharge port 012. After the material tube 01 is installed on the fixed sleeve 1, the discharge port 012 faces downward, and the limit ring 011 is stuck on the top of the fixed sleeve 1, and the limit ring 011 prevents the material tube 01 from sliding downward.

[0026] A hinged portion 2 is fixedly connected to the outside of the fixed sleeve 1. The hinged portion 2 and the fixed sleeve 1 are integrally formed. The top of the hinged portion 2 is higher than the top of the material tube 01 installed on the fixed sleeve 1. A handle 3 is hinged to the top of the hinged portion 2. The handle 3 is L-shaped. The short part of the L-shaped handle 3 spans the top of the fixed sleeve 1. The long part of the L-shaped handle 3 is arranged on one side of the fixed sleeve 1 and vertically downward. The long part of the L-shaped handle 3 has an arc to meet the ergonomics of human hand holding, and the handle 3 can rotate along the hinge between itself and the hinged portion 2.

[0027] A through hole 31 is formed in the short part of the handle 3 and is passed through from top to bottom. The rod body 4 is inserted into the through hole. A ratchet 42 is formed on a side of the rod body 4 away from the hinge part 2 .

[0028] The short part of the handle 3 is provided with a pin slot 502 that penetrates the handle 3. The pin slot 502 has an elliptical slot with an arc shape. The use of the elliptical slot with an arc shape can prevent the pin 52 from slipping off the ratchet 42 when the handle 3 is opened to the maximum angle. The pin 52 is inserted into the pin slot 502, and the pin 52 can slide along the pin slot 502. The handle 3 is also provided with a spring slot 501. One end of the spring slot 501 leads to the pin slot 502, and the other parts are arranged inside the handle 3. A spring 51 is placed in the spring slot 501. One end of the spring 51 abuts against the bottom of the spring slot 501, and the other end can extend into the pin slot 502 and abut against the pin 52 in the pin slot 502. Under the push of the spring 51, the pin 52 is always on the side of the pin groove 502 away from the spring groove 501, which is located at the ratchet 42 of the rod body 4; at this time, the pin 52 can cooperate with the ratchet 42 to block the upward movement trend of the rod body 4, and when the rod body 4 moves downward, the pin 52 can press the spring 51 to enable itself to slide in the pin groove 502, and when the rod body 4 moves to the next tooth, the spring 51 resets the pin 52, thereby completing the unidirectional movement of the rod body 4.

[0029] Preferably, both ends of the pin 52 extend out of the handle 3, and both ends of the pin 52 are detachably connected with a pin button 521. Specifically, both ends of the pin 52 may be installed with threads, and the pin button 521 is provided with a screw hole, and the pin 52 and the pin button 521 may be threadedly connected to each other. The function of the pin button 521 is that when the push rod needs to be retracted after the glue is squeezed, the user can also operate the pin 52 by toggling the pin button 521 so that the pin 52 presses the spring 51 so that the pin 52 leaves the ratchet 42 on the push rod, so that the rod body 4 returns to the top.

[0030] Preferably, a curved surface 32 is provided on one side of the through hole 31 away from the ratchet 42. The curved surface 32 is a curved surface formed by a cylinder with the hinge axis of the handle 3 and the hinge part 2 as the axis, and the curved surface 32 can ensure that the rod body 4 remains vertical and not skewed when moving up and down.

[0031] Preferably, a pipe plug seat 61 is fixedly connected to the bottom of the rod body 4, and the pipe plug seat 61 is fixedly connected to the pipe plug 6. Two pipe plug wide clamps 610 are installed on the pipe plug seat 61. The pipe plug wide clamps 610 are elastic, and the pipe plug wide clamps 610 expand outward in a direction away from the axial center line of the pipe plug 6. When the pipe plug 6 enters the interior of the material pipe 01, the pipe plug wide clamps 610 can expand outward to support the inner wall of the material pipe 01, slightly increasing the friction with the material pipe 01, so that when the handle 3 is rotated outward, the friction force of the pipe plug 61 against the inner wall of the material pipe 01 is greater than the friction force of the pin shaft 52 on the push rod 4, so that the push rod 4 and the pipe plug 6 will not slide upward and cause failure of pushing the material next time.

[0032] Preferably, a square hole is provided in the middle of the pipe plug seat 61, and a cross bar 611 is fixedly connected in the square hole. A torsion spring 62 is sleeved on the cross bar 611, and bent portions 621 are provided at both ends of the torsion spring 62. When the torsion spring 62 enters the interior of the material tube 01, the two bent portions 621 of the torsion spring 62 can expand outwards to support the inner wall of the material tube 01, slightly increasing the friction with the material tube 01, so that when the handle 3 is rotated outward, the friction force of the pipe plug 61 against the inner wall of the material tube 01 is greater than the friction force of the pin shaft 52 on the push rod 4, so that the push rod 4 and the pipe plug 6 will not slide upward and cause failure of pushing the material next time.

[0033] Preferably, a push handle 41 is fixedly connected to the top of the rod body 4, and the push handle 41 and the rod body 4 are integrally formed, so that the push handle 41 can be convenient for a user to press downward.

[0034] In summary, in actual use, the user needs to first open the handle 3 around the hinge 2, put the material tube 01 into the fixed sleeve 1, and then close the handle 3. At this time, the pipe plug 6 at the bottom of the rod body 4 will be inserted into the material tube 01. On the one hand, the user can press the handle 41 at the top of the rod body 4 to push out the material in the material tube 01; on the other hand, the user can rotate the handle 3, and the pin 52 in the handle 3 cooperates with the ratchet 42, so that the rod 4 can only move downward relative to the handle 3. The pin 52 climbs up along the rod 4 and then resets under the action of the torsion spring 501. Then, the handle 3 is squeezed. Under the cooperation of the pin 52 and the ratchet 42, the handle 3 drives the rod 4 to move downward. As the handle 3 is squeezed, the material can be squeezed out continuously and evenly by the user.

[0035] Therefore, the extruder can achieve continuous and uniform extrusion and precise glue dispensing; since the ratchet teeth 42 are uniform, quantitative extrusion can be achieved according to the number of teeth, and unskilled workers can also easily control the glue dispensing pressure and speed. The device is easy to operate and suitable for large-scale use.

[0036] Of course, the present invention may have many other embodiments.
