Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cooking equipment, and particularly to an improved structure of an electric oven supporting column. BACKGROUND

[0002] In the field of design and manufacture of cooking devices, the burner is installed on the supporting column, and when the burner needs to rotate, there is a gap between the burner and the supporting column to realize the function of rotating the burner. However, in the actual production and use process, due to the thermal expansion and contraction characteristics of the material itself and the unavoidable tolerance problem in the manufacturing process, a large gap often appears between the burner and the supporting column. These gaps not only seriously affect the appearance of the product, reducing the consumer's preference and acceptance of the product, but also cause the burner to shake during use, greatly reducing the stability of the burner and affecting the accuracy of cooking operations. It may even cause safety hazards and reduce the overall performance and service life of the cooking device. At present, there is no effective and mature solution to the above problems, and the installation structure of the burner and the supporting column needs to be improved and optimized. SUMMARY

[0003] The utility model aims at solving the above technical problem, and provides an improved structure of an electric oven supporting column. The present application solves the problem of gaps between the burner and the supporting column caused by thermal expansion and contraction or manufacturing tolerance.

[0004] An improved structure of an electric oven supporting column includes a burner, a supporting column, a column body, and an elastic member. The burner is installed on the supporting column. The burner has a first housing, and the supporting column has a second housing. The first housing and the second housing have opposite contact surfaces. The lower end of the column body is fixed in the second housing, the middle part passes through the contact surface, and the upper end extends into the first housing. The upper end of the column body is provided with a first abutting plate. The first housing extends towards the column body and has a first abutting part. The upper end of the elastic member abuts on the first abutting plate, and the lower end abuts on the first abutting part. The elastic force of the elastic member acts on the burner to keep the contact surfaces in contact.

[0005] According to the improved structure of the electric oven supporting column, the installed elastic member is in a compressed state. The elastic member exerts a downward pressure on the first abutting part. Since the first abutting part extends from the first housing, the downward pressure is transmitted to the entire burner through the first abutting part. When a gap appears between the contact surfaces of the burner and the supporting column, the downward pressure will cause the burner to move downward along the column body as a whole, so that the contact surfaces of the burner and the supporting column always remain in contact.

[0006] The improved structure of the electric oven support column comprises a stove head, a support column, a column body and a spring. The stove head is arranged on the support column. The stove head has a first shell. The support column has a second shell. The first shell and the second shell have opposite contact surfaces. The lower end of the column body extends into the second shell, passes through the contact surfaces and extends into the first shell. The upper end of the column body is provided with a first abutting plate. The first shell extends to the column body and has a first abutting part. The first abutting plate is pressed on the first abutting part. The lower end of the column body is provided with a second abutting plate. The second shell is provided with a second abutting part. The spring is abutted on the second abutting part at the upper end and is abutted on the second abutting plate at the lower end. The spring exerts a pressure on the stove head to keep the contact surfaces in contact.

[0007] According to the improved structure of the electric oven support column, the spring is compressed after installation. The spring exerts a downward pressure on the second abutting plate. The second abutting plate is arranged at the lower end of the column body. The downward pressure is transmitted to the column body. The first abutting plate at the upper end of the column body is abutted on the first abutting part. The downward pressure is transmitted to the first abutting part through the column body. The downward pressure is transmitted to the whole stove head through the first abutting part. When the contact surfaces between the stove head and the support column have a gap, the downward pressure presses the whole stove head to move downward with the column body. The contact surfaces between the stove head and the support column are kept in contact.

[0008] Further, the spring is sleeved on the outer sidewall of the column body. The spring directly limits the upward and downward movement of the column body.

[0009] Further, the first abutting part comprises a fixed plate and a sleeve. The fixed plate is fixed on the first shell. The sleeve is sleeved on the outer sidewall of the column body. The sleeve directly limits the upward and downward movement of the column body. The fixed plate can transmit the upward and downward movement to the first shell, so that the whole stove head moves upward and downward.

[0010] Further, the outer sidewall of the column body is provided with a limiting part. The sleeve is sleeved between the limiting part and the first abutting plate. The limiting part and the first abutting plate cooperate to limit the sleeve in the axial direction of the column body.

[0011] Further, a guide structure is arranged between the sleeve and the first shell. The guide structure guides the upward and downward movement of the sleeve, avoiding the sleeve from being stuck relative to the column body due to the deflection caused by the restraint of the first shell.

[0012] Further, the column body is a hollow wiring pipe body. The first abutting plate is an annular plate body extending outward from the top end of the column body. The connecting line of the support column and the stove head passes through the column body. The first abutting plate is arranged at the top end of the column body. The first abutting plate can be used to form the downward pressure with the spring and can also protect the outlet of the connecting line at the top end of the column body from being cut by the column body.

[0013] Further, the lower end of the column is provided with a fixing screw, and the second abutting plate is clamped and fixed at the lower end of the column by cooperation of the nut and the fixing screw.

[0014] Further, the column is a hollow wiring pipe, and the second abutting plate is provided with a wiring hole opposite to the hollow wiring pipe, so as to avoid the second abutting plate from shielding the wiring structure formed by the column.

[0015] Further, the second abutting part is provided with a through hole, and the lower end of the column extends through the through hole to be connected and fixed with the second abutting plate below the second abutting part. BRIEF DESCRIPTION OF DRAWINGS

The limiting member 33 is a screw fixed on the outer side wall of the column 3. When the product is assembled, the first abutting part 12 needs to be sleeved on the column 3, and the limiting action of the screw also makes it more convenient to install the first abutting part 12 in the first shell 11 after the first abutting part 12 is sleeved on the column 3.

[0031] As shown in the figure, Figure 3 The sleeve 122 and the first shell 11 are provided with a guide structure, which includes a guide groove 123 on the inner side wall of the sleeve 122 and a guide column 111 extending from the guide groove 123 to the first shell.
