Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to a reinforcement device for an automobile engine cylinder cover. Background Art
[0002] The engine cylinder head is mounted on the upper surface of the cylinder block via fixing bolts, sealing the cylinder block from above and forming a combustion chamber. The automobile engine cylinder head is made of cast iron. The automobile engine generates a large amount of heat during operation, and the cylinder head reaches a certain temperature as the engine runs longer. When the engine stops, the temperature drops, and the temperature of the cylinder head also drops. When the vehicle is driven on bumpy roads for a long time, vibrations are transmitted to the various fasteners. This can easily cause the fixing bolts of the cylinder head to loosen and back out when the engine is in an alternating high-temperature and cold environment, as well as in a long-term bumpy road environment. This can cause a loose seal between the engine block and the cylinder head, posing a certain safety hazard. It is also difficult to strengthen and fix the cylinder head, so we have proposed a reinforcement device for automobile engine cylinder heads to address the above-mentioned issues. Utility Model Content
[0003] The main purpose of the utility model is to provide a vehicle engine cylinder head reinforcement device, which can effectively solve the problems in the background technology.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] The top of the bolt sleeve has a hole, and the bottom of the bolt sleeve has a hole, and the bottom of the bolt sleeve has a hole, and the bottom of the bolt sleeve has a hole.
[0006] Preferably, the bottom of the sleeve contacts the top of the backing plate, and the bottom of the backing plate contacts the top of the bolt.
[0007] Preferably, the L-shaped rods are respectively inserted into the inner diameters of the sockets at matching positions, and the outer diameters of the L-shaped rods are respectively matched with the inner diameters of the sockets.
[0008] Preferably, the end of the insertion rod away from the sleeve is inserted into the inside of the through hole, and the outer diameter of the insertion rod matches the inner diameter of the through hole.
[0009] Preferably, shift rods are fixed on both sides of the outer wall of the insertion rod away from one end of the sleeve.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] When the bolt passes through the bolt barrel and is threadedly connected to the thread grooves of the cylinder head seat and the cylinder block seat, the backing plate is placed above the bolt in the bolt barrel, the insertion rod is compressed into the sleeve and embedded in the bolt barrel, the position of the L-shaped rod is aligned with the position of the insertion hole, the position of the insertion rod is aligned with the position of the through hole, and the insertion rod is popped out by the tension of the spring until the L-shaped rod is inserted into the inside of the insertion hole to limit the sleeve, and the insertion rod is inserted into the inside of the through hole to limit the insertion rod. Subsequently, due to the contact between the sleeve and the top of the backing plate, and the contact between the bottom of the backing plate and the top of the bolt, when the thread is withdrawn due to the ambient temperature problem or the bumpy driving problem, the bolt can form a certain limit capacity to it, so that it cannot move up, making the connection between the cylinder block seat and the cylinder head seat more stable, thereby achieving the reinforcement effect of preventing thread withdrawal;
[0012] When disassembly is required, a pair of needle-nose pliers can be used to insert the angle between the sleeve and the two L-shaped rods, and move and compress it toward the position of the insertion rod. A thin rod component can be inserted from the outside of the perforation to push the insertion rod into the bolt barrel, or another pair of needle-nose pliers can be used to insert the angle between the insertion rod and the push rod and compress and move it toward the position of the sleeve, so that the sleeve and the insertion rod can be taken out of the bolt barrel. Then, the bolt can be disassembled after the pad is taken out of the bolt barrel. The operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1-4 As shown, a vehicle engine cylinder head reinforcement device includes a cylinder block seat 1, a cylinder head seat 2 is provided above the cylinder block seat 1, and thread grooves 4 are bored on the cylinder block seat 1 and the cylinder head seat 2 at matching positions. A bolt barrel 3 is fixed to the top of the cylinder head seat 2 at the thread groove 4 position, and a bolt 5 is inserted through the interior of the bolt barrel 3. One end of the bolt 5 passes through the bolt barrel 3 and is respectively inserted into the thread grooves 4 of the cylinder block seat 1 and the cylinder head seat 2 and is threadedly connected thereto. A backing plate 6 is embedded in the interior of the bolt barrel 3 at the position above the bolt 5. A sleeve 7 is provided at one end above the pad 6, and an insertion rod 8 is provided at the other end above the pad 6. One end of the insertion rod 8 is inserted into the interior of the sleeve 7, and a spring 9 is embedded and fixed at the end of the sleeve 7 away from the insertion rod 8. The spring 9 is fixed to the end of the insertion rod 8 inserted into the sleeve 7. L-shaped rods 10 are fixed on both sides of the outer wall of the sleeve 7 away from the insertion rod 8. The inner side wall of the bolt barrel 3 at the position of the L-shaped rod 10 is drilled with a hole 31, and the side wall of the bolt barrel 3 at the position of the insertion rod 8 is drilled with a through hole 32.
[0020] Specifically, the bottom of the sleeve 7 contacts the top of the pad 6, the bottom of the pad 6 contacts the top of the bolt 5, the L-shaped rods 10 are respectively inserted into the inside of the sockets 31 with matching positions, and the outer diameters of the L-shaped rods 10 match the inner diameters of the sockets 31, and the end of the insertion rod 8 away from the sleeve 7 is inserted into the inside of the through hole 32, and the outer diameter of the insertion rod 8 matches the inner diameter of the through hole 32, so that the pad 6 can stably limit the bolt 5.
[0021] Specifically, levers 11 are fixed on both sides of the outer wall of the insertion rod 8 away from the sleeve 7 to facilitate disassembly.
[0022] Working principle:
[0023] After the bolt 5 passes through the bolt barrel 3 and is threadedly connected to the thread groove 4 of the cylinder head seat 2 and the cylinder block seat 1, the backing plate 6 is placed above the bolt 5 in the bolt barrel 3, and the insertion rod 8 is compressed into the sleeve 7 and embedded in the bolt barrel 3, and the position of the L-shaped rod 10 is aligned with the position of the insertion hole 31, and the position of the insertion rod 8 is aligned with the position of the through hole 32. The insertion rod 8 pops out due to the tension of the spring 9 until the L-shaped rod 10 is inserted into the inside of the insertion hole 31, so that the sleeve 7 is limited, and the insertion rod 8 is inserted into the inside of the through hole 32, so that the insertion rod 8 is limited. Subsequently, since the sleeve 7 contacts the top of the backing plate 6 and the bottom of the backing plate 6 contacts the top of the bolt 5, when the ambient temperature problem or the driving bump problem causes the rotation and thread backing, the bolt 5 can form a certain limit capacity for it, so that it cannot move up, making the connection between the cylinder block seat 1 and the cylinder head seat 2 more stable, thereby achieving the reinforcement effect of preventing thread backing;
[0024] When disassembly is required, a pair of needle-nose pliers can be used to insert the angle between the sleeve 7 and the two L-shaped rods 10, so that it can be moved and compressed toward the position of the insertion rod 8, and a thin rod component can be inserted from the outside of the through-hole 32 to push the insertion rod 8 into the bolt barrel 3, or another pair of needle-nose pliers can be used to insert the angle between the insertion rod 8 and the lever 11 and compress and move it toward the position of the sleeve 7, so that the sleeve 7 and the insertion rod 8 can be taken out of the bolt barrel 3, and then the bolt 5 can be disassembled after the pad 6 is taken out of the bolt barrel 3. The operation is simple and convenient.
