DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-7 The purpose of the utility model is to provide a manual glue dispenser, 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.

[0025] 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.

[0026] A through hole 31 is provided at the short part of the handle 3 and is penetrated by a rod 4. A ratchet 42 is provided on the side of the rod 4 away from the hinge 2. A pipe plug 6 is fixedly connected to the bottom of the rod 4 and can push the material in the material tube 01.

[0027] A movable pawl 5 is also hinged in the through hole 31, and the movable pawl 5 is arranged on a side close to the ratchet 42, and a pawl head 52 is fixedly connected to the movable pawl 5, and the pawl head 52 is engaged with the ratchet 42; specifically, an insertion hole 51 is provided on the handle 3, and a round rod is passed through the insertion hole 51, and the movable pawl 5 is hinged on the round rod, and the movable pawl 5 can rotate around the round rod.

[0028] A torsion spring 501 is provided between the movable pawl 5 and the handle 3. Specifically, the torsion spring 501 is sleeved on the round rod, one end of the torsion spring 501 abuts against the movable pawl 5, and the other end is fixedly connected to the handle 3. Therefore, in a non-use state, the torsion spring 501 can drive the movable pawl 5 to reset. When resetting, one side of the movable pawl 5 abuts against the through hole 31, and the pawl head 52 is clamped in the ratchet tooth 42. At this time, the rod body 4 cannot move upward.

[0029] 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.

[0030] Preferably, a tube plug wide clamp 61 is fixedly connected between the tube plug 6 and the rod body 4; specifically, a tube plug wide clamp 61 is fixedly connected to the top of the tube plug 6, and the tube plug wide clamp 61 is fixedly connected to the rod body 4. The tube plug 6 is made of elastic material, such as rubber material, and the tube plug wide clamp 61 can be made of plastic material. Six arc-shaped teeth are evenly arranged around the top of the tube plug 61, that is, gaps are provided between adjacent arc-shaped teeth, and the arc-shaped teeth expand outward in a direction away from the axis of the tube plug 6. When the tube plug 6 enters the interior of the material tube 01, the arc-shaped teeth on the tube plug wide clamp 61 can expand outward 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 tube plug wide clamp 61 on the inner wall of the material tube 01 is greater than the friction force of the pawl 5 on the push rod 4, so that the push rod 4 and the tube plug 6 will not slide upward and cause failure of pushing the material next time.

[0031] Preferably, a push handle 41 is fixedly connected to the top of the rod body 4. The push handle 41 is a disc-shaped structure. The push handle 41 and the rod body 4 are integrally formed. The push handle 41 with a disc-shaped structure can be easily pressed downward by a user.

[0032] Preferably, eight fastening clamps 11 are fixedly connected to the bottom of the fixed sleeve 1. The fastening clamps 11 are integrally formed with the fixed sleeve 1. The fastening clamps 11 are evenly distributed at the bottom of the fixed sleeve 1, and all the fastening clamps 11 gather toward the axis of the fixed sleeve 1. There are gaps between adjacent fastening clamps 11, which makes it elastic. After the material tube 01 is installed in the fixed sleeve 1, the fastening clamps 11 can squeeze the material tube 01 inward, which makes it difficult for the material tube 01 to slip upward after being installed in the fixed sleeve 1, and it can also adapt to material tubes of different diameters.

[0033] 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 movable pawl 5 in the handle 3 cooperates with the ratchet 42, so that the rod body 4 can only move downward relative to the handle 3. The movable pawl 5 climbs up along the rod body 4 and then resets under the action of the torsion spring 501. Then, the handle 3 is squeezed. Under the cooperation of the movable pawl 5 and the ratchet 42, the handle 3 drives the rod body 4 to move downward. As the handle 3 is squeezed, the material can be squeezed out continuously and evenly by the user.

[0034] Therefore, the glue dispenser can achieve continuous and uniform extrusion and precise glue dispensing; since the ratchet teeth 42 are uniform, quantitative material 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.
