Description

Technical Field

[0001] The utility model relates to the field of glass glue boosting mechanisms, and particularly to a transmission type glass glue boosting mechanism. Background Art

[0002] For prefabricated buildings, traditional silicone and polyurethane sealants have obvious defects. Currently, modified silicone (MS) sealants are more preferred for sealing joints in prefabricated buildings. According to different packaging methods, modified silicone sealants can be divided into bucketed sealants, hard-packaged sealants, and soft-packaged sealants (commonly known as sausage sealants). When applying these different types of sealants, a caulking rod is required. However, due to the unstable glue output and uneven glue output speed of the current caulking rod, it is easy to cause waste and needs to be improved. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a transmission type glass glue boosting mechanism to solve the problems raised in the above background art, which has the advantage of stable glue output.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A transmission type glass glue boosting mechanism includes a housing. A driving mechanism and a transmission mechanism are arranged inside the housing. The driving mechanism includes a first gear, and the first gear meshes with a second gear. The transmission mechanism includes a push rod threadedly connected to the middle of the second gear. Planes symmetrically distributed about the center of the push rod are arranged on the side surface of the push rod. A push head is sleeved at one end of the push rod. A limiting member for restricting the rotation of the push rod is arranged inside the housing.

[0005] By adopting the above technical solution, driving the first gear to drive the second gear to rotate. Under the action of the limiting member, the push rod cannot rotate around its own axis but can only move along its own length direction. After the second gear rotates, it can drive the push rod to move and then drive the push head to move. Due to the drive of the first gear and the second gear, the push head can only move at a constant speed, so that the push head evenly presses one end of the glue stick to achieve uniform glue output. Without the push head, the push rod is likely to pierce through the pushing plastic part at the tail of the glue stick during operation, resulting in glass glue leakage and inability to work.

[0006] As a further scheme of the utility model: A driving rod is connected to the middle of the first gear.

[0007] By adopting the above technical solution, an external electric drill is used to drive the driving rod to rotate, thereby driving the first gear to rotate and transmitting to the second gear, achieving the purpose of facilitating the rotation of the push rod.

[0008] As a further solution of the utility model: the shell includes a first shell and a second shell that are clamped to each other, the first shell includes a through groove for the push rod to pass through, the first shell is provided with a plurality of circular holes distributed about the center of the through groove, the limiting member includes a limiting steel ball in the circular hole, and the limiting steel ball abuts against the plane of the push rod.

[0009] By adopting the above technical solution, the limiting steel ball is restricted by the circular hole and can only be located in the circular hole, and the two limiting steel balls are located on one side of the plane of the push rod, so that the push rod cannot rotate.

[0010] As a further solution of the utility model: both sides of the middle part of the second gear are integrally connected with connecting rings protruding outward, the second gear is provided with a bearing through the connecting ring sleeve, a fixing ring for accommodating the bearing is integrally connected with the side of the first shell facing the second shell, and a receiving groove for accommodating the bearing is provided on the side of the second shell facing the first shell.

[0011] By adopting the above technical solution, the fixing ring and the accommodating groove are used to place the bearing, and the bearing sleeve is arranged outside the connecting ring. The arrangement of the bearing facilitates the rotation of the second gear.

[0012] As a further solution of the utility model: a plurality of fixing rods are integrally connected to a side of the second shell facing away from the first shell, and the push head is provided with fixing grooves for accommodating the fixing rods.

[0013] By adopting the above technical solution, the fixing rod is in the fixing groove, and the cooperation between the two plays a role of pre-fixing the push head.

[0014] As a further solution of the utility model: a plurality of threaded plates are integrally connected to the side of the second shell facing away from the first shell, the second shell is integrally connected to a guide plate on one side of the threaded plate, and an extended circular plate is integrally connected to the side of the threaded plate facing away from the guide plate.

[0015] By adopting the above technical solution, after the tail end of the glue stick is clamped on one side of the second shell, the external screw is fixed to the threaded plate, the glue stick tube wall and the guide plate, and the glue stick is fixed by threaded connection. The setting of the extended circular plate facilitates the threaded connection between the external screw and the threaded plate. If there is no extended circular plate, the screw will easily shift and fall when placed in the hole. The setting of the guide plate can guide the external screw.

[0016] As a further solution of the utility model: a polished rod is arranged at one end of the push rod.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The first gear is driven to drive the second gear to rotate. Under the action of the limiting member, the push rod cannot rotate around its own axis but can only move along its own length direction. After the second gear rotates, it will be able to drive the push rod to move and thus drive the push head to move. Due to the drive of the first gear and the second gear, the push head can only move at a uniform speed, so that the push head evenly squeezes one end of the rubber stick to discharge the glue evenly.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In the embodiments of the present invention,

[0029] Embodiment:

[0030] A transmission type glass glue boosting mechanism, such asFigures 1-7 As shown, it includes a shell, in which a driving mechanism and a transmission mechanism are arranged, the driving mechanism includes a first gear 2, the first gear 2 is meshed with a second gear 3, the transmission mechanism includes a push rod 4 threadedly connected to the middle part of the second gear 3, the side of the push rod 4 is provided with a plane 6 symmetrically distributed about the center of the push rod 4, one end of the push rod 4 is sleeved with a push head 5, and a limit piece for limiting the rotation of the push rod 4 is arranged in the shell.

[0031] A driving rod 7 is connected to the middle of the first gear 2 .

[0032] One end of the push rod 4 is connected with a polished rod 28. The setting of the polished rod 28 can prevent the push rod 4 from moving too far, and the thread length of the push rod 4 is set to adapt to the length of the glue stick, so that after the push rod 4 can be pushed to the top of the glue stick, the polished rod 28 will move to the limit steel ball for idling to avoid operating accidents.

[0033] One end of the push rod 4 is rounded to disperse and buffer the force on the push head 5, making it easy to disassemble the push head. If it is set at a right angle, the push head will be stuck and difficult to disassemble.

[0034] The end surface of the push head 5 is set as an arc surface, which can adapt to the end surface of the plastic part pushed by the glue stick and evenly push the force.

[0035] The shell includes a first shell 8 and a second shell 9 that are clamped together. The first shell 8 includes a through slot 10 for the push rod 4 to pass through. The first shell 8 is provided with a plurality of circular holes 11 distributed about the center of the through slot 10. The limiting member includes a limiting steel ball 1 in the circular hole 11, and the limiting steel ball 1 abuts against the plane 6 of the push rod 4.

[0036] The two sides of the middle part of the second gear 3 are integrally connected with a connecting ring 12 protruding outward, and the second gear 3 is provided with a bearing 13 through the connecting ring 12. The side of the first shell 8 facing the second shell 9 is integrally connected with a fixing ring 14 for accommodating the bearing 13, and the side of the second shell 9 facing the first shell 8 is provided with an accommodating groove 15 for accommodating the bearing 13.

[0037] A plurality of fixing rods 16 are integrally connected to a side of the second housing 9 facing away from the first housing 8 , and a fixing groove 17 for accommodating the fixing rods 16 is provided on the push head 5 .

[0038] The second shell 9 is integrally connected to a plurality of threaded plates 18 on one side facing away from the first shell 8 . The second shell 9 is integrally connected to a guide plate 19 on one side of the threaded plates 18 . The threaded plate 18 is integrally connected to an extension circular plate 20 on one side facing away from the guide plate 19 .

[0039] The driving rod 7 includes a first connecting rod 26 and a second connecting rod 27 which are clamped with each other. One end of the second connecting rod 27 is sleeved with a bearing 13 located inside the first housing 8.

[0040] The first connecting rod 26 is in the shape of a screwdriver bit, so that there are no abnormal protrusions on the whole device, which will not damage the packaging and at the same time reduces the volume and storage space, making it convenient to carry. In addition, if the first connecting rod 26 is lost during subsequent use, it can also be replaced by a common screwdriver bit on the market with a little modification.

[0041] The second gear 3 is provided with a plurality of through holes 25 penetrating through the second gear 3. The arrangement of the through holes 25 can reduce the weight of the second gear 3.

[0042] Working principle:

[0043] The first gear 2 is driven to drive the second gear 3 to rotate. Under the action of the limiting member, the push rod 4 cannot rotate around its own axis but can only move along its own length direction. After the second gear 3 rotates, it will be able to drive the push rod 4 to move, thereby driving the push head 5 to move. Due to the drive of the first gear 2 and the second gear 3, the push head 5 can only move at a uniform speed, so that the push head 5 evenly presses one end of the glue stick to extrude the glue evenly.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
