Description

TECHNICAL FIELD

[0001] The utility model relates to lubricating equipment technical field especially relates to a grease gun of can weigh. BACKGROUND

[0002] The grease gun is a kind of manual tool for filling grease to mechanical equipment. It can be equipped with iron gun rod (iron gun head) or hose (flat gun head) oil nozzle. For the oil filling position, it is convenient to use iron gun rod (iron gun head) in the place with spacious space, and it is necessary to use hose (flat gun head) to oil for the concealed oil filling position, winding and cornered place. The grease gun is simple to operate, convenient to carry and widely used, and is the essential tool of the majority of farm hands and maintenance center.

[0003] When using the grease gun to lubricate mechanical equipment, usually, the barrel or bagged grease is sprayed on the position needing lubrication through the gun rod and gun head of the grease gun.

However, in the prior art, the grease gun is usually filled by the feeling of workers, and it is impossible to accurately fill Xg grease. If the grease is filled too much, the internal resistance of the motor will increase, the energy consumption of the motor during operation will increase, the stickiness of the grease will produce additional friction heat, so that the temperature of the motor will rise, which will affect the performance and service life of the motor. This not only does not meet the environmental protection concept of energy saving and emission reduction, but also increases the operating cost of enterprises. If the grease is filled too little, the direct contact between the rotating parts in the motor will be caused, so that a large amount of friction and heat will be generated, which will seriously affect the performance and service life of the motor, and also reduce the working efficiency of the motor.

DETAILED DESCRIPTION

[0033] In order to better understand the above technical solutions, the exemplary embodiments of the utility model will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the utility model are shown in the drawings, it should be understood that the utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided so that the utility model can be more clearly and thoroughly understood, and the scope of the utility model can be completely conveyed to those skilled in the art.

[0034] EMBODIMENT

[0035] The butter gun capable of weighing of the embodiment comprises a gun body 1, a gun head 2, a first gun pipe 3, a second gun pipe 4, a turbine flowmeter 5 and two buckle mechanisms 6.

[0036] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, one end of the first barrel 3 is detachably connected with the oil outlet end of the gun body 1, one end of the second barrel 4 is detachably connected with the gun head 2, and the outer wall of the other end of the first barrel 3 and the other end of the second barrel 4 is respectively provided with two sets of clamping blocks 7, and the two sets of clamping blocks 7 have a spacing therebetween. Two buckle mechanisms 6 are respectively installed at the oil inlet end and the oil outlet end of the turbine flowmeter 5, and the two buckle mechanisms 6 are respectively provided with a clamping end, and the two clamping ends can be respectively placed in the spacing between the two sets of clamping blocks 7. The first barrel 3 and the oil inlet end of the turbine flowmeter 5 and the second barrel 4 and the oil outlet end of the turbine flowmeter 5 are respectively clamped by the two buckle mechanisms 6 and the four sets of clamping blocks 7, so that the turbine flowmeter 5 measures the grease gram weight. By arranging the turbine flowmeter 5, and clamping the turbine flowmeter 5 between the first barrel 3 and the second barrel 4 by the two buckle mechanisms 6 and the two sets of clamping blocks 7, the grease flow through the turbine flowmeter 5 can be measured in real time, so that the operator can accurately add the specified gram weight of grease according to the lubrication demand of the equipment, thereby improving the accuracy of adding grease, avoiding the problems of increased internal resistance of the motor, increased energy consumption and increased temperature caused by adding too much, and also preventing the phenomenon of direct contact and excessive friction of parts caused by insufficient addition, improving the operation efficiency and stability of the equipment, prolonging the service life of the equipment, and reducing the maintenance cost. By arranging the buckle mechanism 6 and the clamping block 7, the turbine flowmeter 5 can be detachably installed between the first barrel 3 and the second barrel 4, realizing the quick installation and disassembly of the turbine flowmeter 5, and improving the flexibility and universality of the grease gun, which is convenient for the operator to maintain the grease gun.

[0037] Further, as shown in the drawings, Figure 5 The turbine flowmeter 5 includes a connecting pipe 51, a turbine 52, a first mounting assembly 53 and a second mounting assembly 54. Two buckle mechanisms 6 are respectively installed at the two ends of the connecting pipe 51, the oil inlet end of the connecting pipe 51 is the oil inlet end of the turbine flowmeter 5, and the oil outlet end of the connecting pipe 51 is the oil outlet end of the turbine flowmeter 5. The first mounting assembly 53 and the second mounting assembly 54 are fixedly installed in the connecting pipe 51 with a spacing, the first mounting assembly 53 is located at the oil inlet end of the turbine flowmeter 5, the second mounting assembly 54 is located at the oil outlet end of the turbine flowmeter 5, the turbine 52 is located between the first mounting assembly 53 and the second mounting assembly 54, and the opposite ends of the turbine 52 and the first mounting assembly 53 and the second mounting assembly 54 are rotatably connected. By arranging the first mounting assembly 53 and the second mounting assembly 54, the turbine 52 can be stably fixed in the connecting pipe 51, and it is ensured that the turbine 52 can rotate smoothly under the action of the flowing grease, which not only improves the sensitivity and response speed of the turbine 52, but also effectively reduces the measurement error caused by mechanical vibration or fluid impact, thereby realizing accurate measurement of the grease addition amount.

[0038] Further, as shown in the drawings, Figure 5As shown, the inner diameter of the two ends of the connecting pipe 51 gradually decreases towards its midpoint, which can effectively accelerate the speed of the butter when passing through the connecting pipe 51, so that the butter can push the turbine 52 to rotate at a higher speed when entering the turbine flow meter 5, thereby improving the sensitivity and accuracy of the turbine flow meter 5 in measuring the weight of the butter. And also can make the butter release from the turbine 52 to the oil outlet end of the connecting pipe 51, so that the flow rate of the butter is slowed down, so that the butter is released from the gun head 2 more smoothly. It should be noted that, as Figure 5 As shown, the diameter of the oil inlet end and the oil outlet end of the connecting pipe 51 is greater than the axis of the connecting pipe 51 where the turbine 52 is located, that is, the diameter of the center of the connecting pipe 51 is smaller than the diameter of the oil inlet end or the oil outlet end of the connecting pipe 51, and the oil inlet end or the oil outlet end of the connecting pipe 51 is tapered to the inner diameter of the center of the connecting pipe 51.

[0039] Further, as Figure 5 As shown, the first mounting assembly 53 includes a conical flow guide 531 and a plurality of connecting pieces 532. The conical flow guide 531 is connected to the inner wall of the connecting pipe 51 through the plurality of connecting pieces 532, and the tip of the conical flow guide 531 is directed towards the oil inlet end of the turbine flow meter 5, for accelerating the flow rate of the butter. By providing the conical flow guide 531, the angle of the turbine 52 can be increased, so that the conical flow guide 531 effectively guides and concentrates the fluid when the butter enters the connecting pipe 51, thereby accelerating the flow rate of the butter, so as to increase the speed of the fluid passing through the turbine 52, so that the turbine flow meter 5 is more sensitive and accurate in measuring the amount of butter filling. The second mounting assembly 54 includes a bearing 541 and a plurality of connecting plates 542, the bearing 541 is connected to the inner wall of the connecting pipe 51 through the plurality of connecting plates 542, and the end of the turbine 52 away from the conical flow guide 531 is rotatably connected with the bearing 541, for fixing the installation of the turbine 52. Preferably, the conical flow guide 531, the turbine 52 and the bearing 541 are coaxially arranged, which can make the rotation of the turbine 52 more stable, and also can make the speed of the butter passing through the conical flow guide 531 faster and more stable.

[0040] Further, as Figure 5As shown, the two buckle mechanisms 6 are structurally identical, each including two sets of buckle assemblies 61. The two sets of buckle assemblies 61 are symmetrically installed at the oil inlet end or the oil outlet end of the connecting pipe 51 along the axis of the connecting pipe 51, and can be located at the interval between the two sets of clamping blocks 7 to cooperate with the two sets of clamping blocks 7 to clamp the connecting pipe 51 with the first barrel 3 and the second barrel 4, achieving quick installation and disassembly of the turbine flowmeter 5 with the first barrel 3 and the second barrel 4, and improving the disassembly efficiency. By symmetrically arranging the two sets of buckle assemblies 61 along the axis of the connecting pipe 51, it can ensure that the clamping between the connecting pipe 51 and the first barrel 3 and the second barrel 4 is more firm, effectively preventing loosening phenomenon caused by the pressure of butter or external vibration, and improving the stability of installation. The opposite ends of the two sets of buckle assemblies 61 are clamping ends.

[0041] Further, as Figure 6As shown, the two sets of snap-fit ​​assemblies 61 have the same structure, each including a snap-fit ​​member 611, a connecting rod 612, an elastic member 613, a fixing plate 614, and a pull ring 615. A groove 511 is provided on the inner wall of the connecting tube 51, and an installation space 512 is provided within the tube wall. The snap-fit ​​member 611 is located within the groove 511, which provides space for movement. This ensures that when the snap-fit ​​member 611 is disengaged from the two sets of snap-fit ​​blocks 7, the outer wall of the snap-fit ​​member 611 that is in contact with the first barrel 3 or the second barrel 4 extends beyond the outer wall of the snap-fit ​​block 7, away from the first barrel 3 or the second barrel 4. This ensures the disassembly of the connecting tube 51 from the first barrel 3 and the second barrel 4 and avoids jamming. Preferably, the groove 511 is an arc-shaped groove 511, and the two grooves 511 on the same side can connect to form an ellipse, so that the two snap-fit ​​members 611 on the same side can enter the groove 511 and engage with the first barrel 3 or the second barrel 4. The snap-fit ​​component 611 can be placed in the gap between the two sets of snap-fit ​​blocks 7, and the two side walls of the snap-fit ​​component 611 can fit against the opposite side walls of the two sets of snap-fit ​​blocks 7. One end of the connecting rod 612 passes through the outer wall of the connecting pipe 51, the installation space 512 and the groove 511 in sequence, and connects to the outer wall of the snap-fit ​​component 611 facing the groove 511. The snap-fit ​​component 611 is the snap-fit ​​end. By setting the pull ring 615, the connecting rod 612 and the snap-fit ​​component 611, it is possible to move the connecting rod 612 and the snap-fit ​​component 611 by simply pulling the pull ring 615, thereby realizing the snap-fit ​​and disengagement of the snap-fit ​​component 611 with the two sets of snap-fit ​​blocks 7, improving the efficiency of disassembly and assembly. Both the elastic element 613 and the fixing plate 614 are located within the installation space 512, and both the elastic element 613 and the fixing plate 614 are sleeved on the outer wall of the connecting rod 612. One end of the elastic element 613 is connected to the fixing plate 614, and the other end is connected to the end of the installation space 512 away from the snap-fit ​​element 611. The elastic element 613 is used to provide a rebound force for the fixing plate 614. When the operator releases the pull ring 615, the elastic element 613 can push the snap-fit ​​element 611 back to the gap between the two sets of snap-fit ​​blocks 7 through its own rebound force, so as to realize the quick snap-fit ​​between the connecting tube 51 and the first gun barrel 3 and the second gun barrel 4. Furthermore, the elastic element 613 can continuously provide pressure to the fixing plate 614, thereby ensuring the tight fit between the snap-fit ​​element 611 and the first gun barrel 3 or the second gun barrel 4, and improving the stability and reliability of the snap-fit ​​between the connecting tube 51 and the first gun barrel 3 and the second gun barrel 4. When the operator pulls the pull ring 615, the connecting rod 612 causes the locking piece 611 to move along the axis of the connecting rod 612 toward the groove 511, thereby disengaging the locking piece 611 from the two sets of locking blocks 7. This allows for quick disassembly of the connecting tube 51 from the first gun barrel 3 and the second gun barrel 4, thus improving the efficiency of disassembly and assembly of the connecting tube 51 from the first gun barrel 3 and the second gun barrel 4. The pull ring 615 is installed at the end of the connecting rod 612 furthest from the locking piece 611.

[0042] Furthermore, such as Figure 2 and Figure 3As shown, each group of clamping blocks 7 is provided with at least two clamping blocks 7, which are symmetrically arranged on the outer wall of the first barrel 3 or the second barrel 4 along the axis of the first barrel 3 or the second barrel 4, so that the clamping piece 611 is more stable when clamped with the clamping block 7, and the first barrel 3 and the second barrel 4 are prevented from being deviated due to the pressure of the butter from the connecting pipe 51, thereby improving the stability and firmness of the clamping.

[0043] Further, as shown, Figure 7 the clamping piece 611 is a semicircular structure, and the opposite ends of the two clamping pieces 611 in the same group of buckle assemblies 61 can be fitted, and the inner contour of the two clamping pieces 611 after fitting is consistent with the outer contour of the first barrel 3 or the second barrel 4, so as to seal the clamping part of the first barrel 3 or the second barrel 4 and the connecting pipe 51, thereby effectively preventing the butter from leaking from the clamping part during high-pressure transmission, and improving the sealing performance. Moreover, by fitting the opposite ends of the two clamping pieces 611 in the same group of buckle assemblies 61, a stable clamping between the connecting pipe 51 and the first barrel 3 and the second barrel 4 can be formed, thereby improving the stability of the clamping and effectively preventing the turbine flowmeter 5 from loosening due to the pressure of the butter or external vibration.

[0044] Further, as shown, Figure 8 the cross section of the clamping piece 611 includes a first transverse section 6111, a second transverse section 6112, two vertical sections 6113 and two inclined sections 6114. The first transverse section 6111 is always located in the groove 511, one end of each of the two vertical sections 6113 is connected to both ends of the first transverse section 6111, the other end of each of the two vertical sections 6113 is connected to one end of each of the two inclined sections 6114, and the other end of each of the two inclined sections 6114 is connected to both ends of the second transverse section 6112. A part of each of the two vertical sections 6113 close to the first transverse section 6111 can be fitted with the two side walls of the groove 511, and the other part can be fitted with the two groups of clamping blocks 7. By always locating the first transverse section 6111 in the groove 511, a part of each of the two vertical sections 6113 close to the first transverse section 6111 can be limited once with the groove 511, and the other part of each of the two vertical sections 6113 can be fitted with the two groups of clamping blocks 7, so that the two vertical sections 6113 can be limited twice with the two groups of clamping blocks 7, thereby preventing the connecting pipe 51 from being separated from the first barrel 3 and the second barrel 4 under the pressure of the butter or external vibration, and improving the connection stability between the connecting pipe 51 and the first barrel 3 and the second barrel 4.

[0045] The two inclined segments 6114 are inclined towards the midpoint of the second transverse segment 6112, which can form a guide structure. When the operator inserts the connecting pipe 51 into the first barrel 3 or the second barrel 4, the inclined segments 6114 can guide the clamping piece 611 to smoothly slide into the space between the two groups of clamping blocks 7, making the operation more smooth and convenient. The length of the first transverse segment 6111 is greater than the length of the second transverse segment 6112, and the second transverse segment 6112 can be in close contact with the outer wall of the first barrel 3 or the second barrel 4, so as to realize sealing at the clamping position of the connecting pipe 51 and the first barrel 3 and the second barrel 4.

[0046] Further, as shown in Figure 7 and Figure 8 , the buckle assembly 61 further comprises a sealing gasket 616. The sealing gasket 616 is also a semicircular structure, and the sealing gasket 616 is installed on the inner wall of the clamping piece 611, i.e. the inner wall where the second transverse segment 6112 is located. The clamping piece 611 is in close contact with the outer wall of the first barrel 3 or the second barrel 4 through the sealing gasket 616, which can form a seal at the clamping position of the connecting pipe 51 and the first barrel 3 and the second barrel 4, improve the sealing performance, effectively prevent the butter from leaking from the connection during high-pressure transmission, and ensure the stability and accuracy of the butter filling process. Preferably, the two side walls of the sealing gasket 616 are flush with the two ends of the second transverse segment 6112, so that the sealing gasket 616 can smoothly enter between the two groups of clamping blocks 7, avoiding jamming.

[0047] Further, a temperature sensor (not shown in the figure) is arranged inside the meter head 55, which can be used to detect the temperature of the butter entering the connecting pipe 51, so as to avoid the change of the viscosity of the butter caused by the change of the temperature, which leads to the different rotation speed of the turbine 52, and improve the measurement accuracy of the turbine flowmeter 5.

[0048] Through the above structure, the installation process of the butter gun capable of measurement of the embodiment is as follows:

[0049] As Figure 1As shown, first, one end of the first barrel 3 is connected with the oil outlet end of the gun body 1, then two pull rings 615 at the oil inlet end of the connecting pipe 51 are pulled at the same time, so that the clamping pieces 611 are driven by the connecting rods 612 to move along the axis of the connecting rods 612 to the direction away from the first barrel 3, at this time, the two elastic pieces 613 are compressed by the action of the two fixed plates 614 respectively, so that the inner wall of the clamping piece 611 towards the first barrel 3 exceeds the outer wall of the clamping block 7 away from the first barrel 3, and the end of the first barrel 3 away from the gun body 1 is inserted into the oil inlet end of the connecting pipe 51. Then the two pull rings 615 are loosened, so that the sealing end and the clamping piece 611 slide into between the two groups of clamping blocks 7 through the inclined section 6114 of the clamping piece 611, and the two vertical sections 6113 of the clamping piece 611 can be attached to the two groups of clamping blocks 7 respectively, in the process, the elastic piece 613 rebounds, and always provides a rebound force to the fixed plate 614, so that the two clamping pieces 611 can be stably attached to the first barrel 3, and the stable clamping of the clamping piece 611 and the first barrel 3 is realized. The oil outlet end of the connecting pipe 51 is also clamped with one end of the second barrel 4 through the above operation, which will not be described here. Finally, the gun head 2 is connected with the other end of the second barrel 4, and the installation of the yellow oil gun is completed. When the yellow oil gun of the embodiment is used to spray yellow oil, the turbine flow meter 5 can measure the yellow oil, so that when the motor and other equipment are filled with yellow oil, a certain amount of yellow oil can be added more accurately, so that the motor and other equipment can run more smoothly.

[0050] It should be noted that the working principle of the turbine flow meter 5 adopted in the embodiment is the working principle of the prior art, that is, how to measure the weight of yellow oil through the rotation of the turbine 52, which will not be described here.
