Description

Technical Field

[0001] This utility model relates to the field of oil pump technology, and in particular to an automatic preheating device for oil pumps. Background Technology

[0002] An automatic oil pump preheating device is a device used to ensure that the oil pump can start and operate normally in low-temperature environments. It improves the fluidity of engine oil or fuel and reduces its viscosity by preheating the oil pump and its related components, thereby ensuring that the oil pump can smoothly draw and supply oil when starting.

[0003] When installing the automatic preheating device for the oil pump, the device is mainly fixed to the oil pump by means of threaded connection between the threaded pipe on the device and the inner wall of the connector on the oil pump. However, the car will inevitably experience bumps during operation. Prolonged bumps may cause the connection between the threaded pipe and the oil pump to loosen. In severe cases, the preheating device may detach from the oil pump, affecting the normal operation of the oil pump. Utility Model Content

[0004] This utility model proposes an automatic oil pump preheating device to address the problem that automobiles inevitably experience bumps during operation, which over a long period of time may cause the connection between the threaded pipe and the oil pump to loosen, and in severe cases, cause the preheating device to detach from the oil pump, affecting the normal operation of the oil pump.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic preheating device for an oil pump, comprising a housing, a metal heating tube at one end of the housing, one end of the metal heating tube being fixedly connected to the inner wall of the housing, a threaded tube fixedly connected to the outer surface of the housing, a negative terminal fixedly connected to the other end of the housing, an insulating washer sleeved on the outer surface of the negative terminal, a fixing device being provided between the insulating washer and the housing, an auxiliary device being provided on the outer surface of the housing, the auxiliary device comprising two sleeves, one end of the two sleeves being fixedly connected to the outer surface of the housing, the sleeves being positioned between the threaded tube and the negative terminal, a rectangular rod being slidably connected to the inner wall of the sleeves, a clamping plate being fixedly connected to the far ends of the two rectangular rods, an extension block being fixedly connected to one side of the clamping plate, a threaded rod being provided on the inner wall of the extension block, a threaded cylinder being threadedly connected to the outer surface of the threaded rod, a common L-shaped plate being fixedly connected to one end of the two threaded cylinders, and one end of the L-shaped plate being fixedly connected to the outer surface of the housing.

[0006] The effect achieved by the above components is as follows: by setting two clamping plates, under the action of two threaded rods, rotating the threaded rods will cause the threaded rods to extend and retract on the inner wall of the threaded cylinder. During the extension and retraction of the threaded rods, the clamping plates connected to the extension block will move. The clamping plates will cause the rectangular rod to slide synchronously on the inner wall of the sleeve until the two clamping plates completely clamp the outer surface of the oil pump. This can provide auxiliary fixation between the housing and the oil pump, which helps to prevent the connection between the threaded pipe and the oil pump from loosening or separating, and ensures that the oil pump can work normally.

[0007] Preferably, a slider is fixedly connected to one side of the inner wall of the sleeve, and a groove is provided on one side of the rectangular rod, with the outer surface of the slider slidably connected to the inner wall of the groove.

[0008] The effect achieved by the above components is that, by setting up sliders and grooves, when the rectangular rod slides on the inner wall of the sleeve, it will drive the slider to slide synchronously on the inner wall of the groove, which can play a role in limiting and guiding the rectangular rod and the sleeve.

[0009] Preferably, a bearing is fixedly connected to the outer surface of the threaded rod, and the outer surface of the bearing is fixedly connected to the inner wall of the extension block.

[0010] The effect achieved by the above components is that by setting bearings, the friction between the threaded rod and the extension block can be reduced when rotating the threaded rod, making it easier to rotate the threaded rod.

[0011] Preferably, each of the two threaded rods has an operating block fixedly connected to one of its far ends, and the outer surface of the operating block is provided with a protrusion.

[0012] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0013] Preferably, a rubber plate is fixedly connected to one side of each of the two clamping plates that are close to each other, and a groove is uniformly formed on one side of the rubber plate.

[0014] The effect achieved by the above components is that by setting a rubber plate with grooves, the friction on one side of the clamping plate can be increased, thereby making the clamping of the oil pump by the two clamping plates more stable.

[0015] Preferably, the fixing device includes a plug, one side of which is fixedly connected to one side of an insulating pad, the outer surface of the negative end is inserted into the inner wall of the plug, and a ring is fixedly connected to one end of the housing, with the outer surface of the plug inserted into the inner wall of the ring.

[0016] The effect achieved by the above components is as follows: by setting the insert and the ring, the insert is inserted into the inner wall of the ring, and the inner wall of the ring can squeeze the insert, causing the insert to deform, thereby connecting and fixing one end of the housing and the insulating gasket, which helps to prevent the insulating gasket from easily detaching from the negative terminal.

[0017] Preferably, auxiliary blocks are symmetrically fixedly connected to the outer surface of the insulating pad, a pin is fixedly connected to one side of the auxiliary block, and a circular hole block is symmetrically fixedly connected to the outer surface of the ring, with the outer surface of the pin inserted into the inner wall of the circular hole block.

[0018] The effect achieved by the above components is that by setting a pin and a round hole block, inserting the pin into the inner wall of the round hole block can further fix the insulating gasket and the housing.

[0019] Preferably, one end of the pin is fixedly connected to a rubber block, and the cross-section of the rubber block is an isosceles trapezoid.

[0020] The effect achieved by the above components is as follows: by setting a rubber block, one end of the rubber block is smaller, which makes it easier to insert into the inner wall of the round hole block, while the other end of the rubber block is larger, which can limit one end of the pin and help prevent the pin from dislodging from the inner wall of the round hole block.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting two clamping plates, the threaded rods can drive the clamping plates to move under the action of the two threaded rods until the two clamping plates completely clamp the outer surface of the oil pump. This can provide auxiliary fixation between the housing and the oil pump, which helps to prevent the connection between the threaded pipe and the oil pump from loosening or separating, and ensures that the oil pump can work normally.

[0028] Example 1, referring to Figures 1-3 As shown, this embodiment discloses an automatic preheating device for an oil pump, including a housing 1. A metal heating tube 2 is provided at one end of the housing 1, and one end of the metal heating tube 2 is fixedly connected to the inner wall of the housing 1. A threaded tube 3 is fixedly connected to the outer surface of the housing 1. A negative terminal 4 is fixedly connected to the other end of the housing 1. An insulating washer 5 is sleeved on the outer surface of the negative terminal 4. A fixing device 6 is provided between the insulating washer 5 and the housing 1. An auxiliary device 7 is provided on the outer surface of the housing 1. The auxiliary device 7 includes two sleeves 71, one end of which is connected to the outer surface of the housing 1. The outer surface is fixedly connected. Sleeve 71 is set between threaded tube 3 and negative end 4. Rectangular rods 72 are slidably connected to the inner wall of sleeve 71. Clamping plates 73 are fixedly connected to the ends of the two rectangular rods 72 that are far apart. An extension block 74 is fixedly connected to one side of clamping plate 73. Threaded rods 75 are provided on the inner wall of extension block 74. Threaded cylinders 76 are threadedly connected to the outer surface of threaded rods 75. The same L-shaped plate 77 is fixedly connected to one end of the two threaded cylinders 76. One end of the L-shaped plate 77 is fixedly connected to the outer surface of shell 1. The metal heating tube 2 and shell are then connected together. The body 1 is inserted into the oil pump, bringing the metal heating tube 2 close to the injector nozzle. The housing 1 and the oil pump are fixed together by the threaded tube 3. At this time, the negative terminal 4 is connected to the positive terminal of the car's power supply. After the power is turned on, the temperature of the metal heating tube 2 will rise rapidly to a very high temperature. Through heat transfer, the oil pump will reach a high temperature. This preheating will increase the ignition temperature of the fuel, making combustion easier during cold starts and reducing starting difficulties and incomplete combustion. By setting two clamping plates 73, under the action of two threaded rods 75, rotating the threaded rods 75 will cause them to extend and retract on the inner wall of the threaded cylinder 76. During the extension and retraction of the threaded rods 75, the clamping plates 73 connected to the extension block 74 will move. The clamping plates 73 will cause the rectangular rod 72 to slide synchronously on the inner wall of the sleeve 71 until the two clamping plates 73 completely clamp the outer surface of the oil pump. This will provide auxiliary fixation between the housing 1 and the oil pump, which will help prevent the connection between the threaded tube 3 and the oil pump from loosening or detaching, ensuring that the oil pump can work normally.

[0029] Reference Figure 2 and Figure 3As shown, a slider 78 is fixedly connected to one side of the inner wall of the sleeve 71, and a groove 79 is provided on one side of the rectangular rod 72. The outer surface of the slider 78 is slidably connected to the inner wall of the groove 79. By setting the slider 78 and the groove 79, when the rectangular rod 72 slides on the inner wall of the sleeve 71, it will drive the slider 78 to slide synchronously on the inner wall of the groove 79, which can play a role in limiting and guiding the rectangular rod 72 and the sleeve 71. A bearing 710 is fixedly connected to the outer surface of the threaded rod 75. The outer surface of the bearing 710 is fixedly connected to the inner wall of the extension block 74. By setting the bearing 710, the friction between the threaded rod 75 and the extension block 74 can be reduced when rotating the threaded rod 75, making it easier to rotate the threaded rod 75.

[0030] Reference Figure 2 and Figure 3 As shown, each of the two threaded rods 75 has an operating block 711 fixedly connected to its far end. The outer surface of the operating block 711 has protrusions. By setting the operating block 711, rotating the operating block 711 can drive the threaded rod 75 to rotate. At the same time, the protrusions on the outer surface of the operating block 711 can effectively increase the friction of the outer surface of the operating block 711, which has an anti-slip effect when rotating the operating block 711. Each of the two clamping plates 73 has a rubber plate 712 fixedly connected to its close side. The rubber plate 712 has grooves evenly opened on one side. By setting the rubber plate 712 with grooves, the friction on one side of the clamping plate 73 can be increased, thereby making the clamping of the oil pump by the two clamping plates 73 more stable.

[0031] Reference Figure 2 and Figure 4 As shown, the fixing device 6 includes a plug 61, one side of which is fixedly connected to one side of the insulating pad. The outer surface of the negative terminal 4 is inserted into the inner wall of the plug 61. One end of the housing 1 is fixedly connected to a ring 62. The outer surface of the plug 61 is inserted into the inner wall of the ring 62. By setting the plug 61 and the ring 62, the plug 61 is inserted into the inner wall of the ring 62. The inner wall of the ring 62 can squeeze the plug 61, causing the plug 61 to deform. This allows for connection and fixation between one end of the housing 1 and the insulating pad, which helps prevent the insulating pad from easily detaching from the negative terminal 4.

[0032] Reference Figure 2 and Figure 4As shown, auxiliary blocks 63 are symmetrically fixedly connected to the outer surface of the insulating gasket. A pin 64 is fixedly connected to one side of the auxiliary block 63. A circular hole block 65 is symmetrically fixedly connected to the outer surface of the ring 62. The outer surface of the pin 64 is inserted into the inner wall of the circular hole block 65. By setting the pin 64 and the circular hole block 65, the pin 64 can be inserted into the inner wall of the circular hole block 65, which can further fix the insulating gasket and the housing 1. A rubber block 66 is fixedly connected to one end of the pin 64. The cross-section of the rubber block 66 is an isosceles trapezoid. By setting the rubber block 66, one end of the rubber block 66 is smaller, which is convenient to insert into the inner wall of the circular hole block 65. At the same time, the other end of the rubber block 66 is larger, which can limit one end of the pin 64 and help prevent the pin 64 from dislodging from the inner wall of the circular hole block 65.

[0033] Working principle: When auxiliary fixing is required between the housing 1 and the oil pump, rotating the two operating blocks 711 causes the threaded rod 75 to extend and retract on the inner wall of the threaded cylinder 76. During the extension and retraction, the threaded rod 75 will drive the clamping plate 73 connected to the extension block 74 to move. The clamping plate 73 will drive the rectangular rod 72 to slide synchronously on the inner wall of the sleeve 71, and drive the slider 78 to slide synchronously on the inner wall of the groove 79 until the rubber plate 712 on one side of the two clamping plates 73 completely clamps the outer surface of the oil pump. This can provide auxiliary fixing between the housing 1 and the oil pump, which helps to prevent the connection between the threaded pipe 3 and the oil pump from becoming loose or detaching. Inserting the insert block 61 into the inner wall of the ring 62 and inserting the rubber block 66 and the pin 64 into the inner wall of the round hole block 65 can connect and fix one end of the housing 1 and the insulating gasket, which helps to prevent the insulating gasket from easily detaching from the negative terminal 4 and causing it to be easily lost.
